DETAILED DESCRIPTION OF THE EMBODIMENTS
In what follows, embodiments of the present invention will be described with reference to the drawings.
(First Embodiment) [0018] FIG. 1 is a schematic view illustrating a configuration of an electronic device 1 comprising a driving unit of a needle according to a first embodiment. The electronic device 1 according to the first embodiment is, for example, a "smart watch" (which is also referred to as "connected watch") with a wireless communication function ("wireless"). For example, the electronic device 1 is actuated according to the control commands of an external device. Moreover, the electronic device 1 can be an electronic timepiece that can execute a program received from the external device, such as a terminal 20. Moreover, the electronic device 1 can be an electronic timepiece that accesses a network with a relay device, such as a base station or router, and downloads the program.
The electronic device 1 comprises, for example, an oscillation circuit 2, an actuating part 3, a main control part 4, a first needle driving unit 5, and a communication part 10. Moreover, , the electronic device 1 comprises a strap (mounting portion) BL (see Fig. 4 to be described later) portable to the arm, wrist or the like. Moreover, the electronic device 1 communicates with the terminal 20, and sends and receives information. The terminal 20 is, for example, a smartphone (multifunctional mobile phone), a tablet, a personal computer, a portable game console, a home network device, an embedded system or the like.
The oscillation circuit 2, the actuating part 3, and the communication part 10 are connected to the main control part 4. The main control part 4 is arranged on a support (substrate) which is different of the support 51, on which the first needle driving unit 5 - which will be described later - is disposed, and is connected to the first needle driving unit 5 via a number "n" ("n" being an arbitrary number ) of transmission circuits WR. The number of transmission circuits WR can be modified according to the type of signal to be transmitted at the output to the first driving motor unit 5 from the main control part 4. According to this embodiment, an example will be described, by way of example an example in which 6 (n = 6) transmission circuits WR are connected to the main control part 4 and to the first driving unit of a needle 5. The transmission circuit WR is an example of a "connecting part" .
The oscillation circuit 2 comprises, for example, a crystal resonator of 32.768 kHz, and divides the signal generated by the crystal resonator, generates a reference signal for measuring the time in the main control part 4, and outputs the reference signal at the output to the main control part 4.
The actuating portion 3 is, for example, a push button or rotary. In the case where the actuating part 3 is actuated (for example, by means of a rotation operation or a pressing action) by a user, the actuating part 3 delivers an actuating signal which corresponds to the operation of the main control part 4. The actuation signal may comprise, for example, a control of adjustment of the position of each hand (setting the time), a start control command of a chronograph, an end of measure chronograph command, a chronograph reset command, or the setting of an alarm.
The communication part 10 sends and receives the command or the information between the communication part 10 and the terminal 20, for example, using the technology according to the standard "wireless fidelity" (Wi-Fi) or Bluetooth ( registered trademark), low energy (LE) (hereinafter referred to as BLE). The command received from the terminal 20 comprises, for example, a command for manipulating the needle by moving it forward or back by one second, a command for driving the needle at a predetermined angle in the forward direction (in the direction of clockwise), a command for driving the needle at a predetermined angle in the opposite direction (counterclockwise), a command to count down by one second (ie say manipulate the needle by "-1 second") using the current time as a reference, a command to actuate the needle continuously, or a command to stop the manipulation of the needle by + 1 or -1 second.
The communication part 10 delivers the information received from the terminal 20 at the output to the main control part 4. Moreover, the communication part 10 sends the information delivered by the canceled main part 4 to the device external, such as the terminal 20. The information output by the main control part 4 may include, for example, a response to the information received from the terminal 20, information indicating the number of units contained in the electronic device 1, information indicating the number of needles provided on the electronic device 1, etc.
The main control part 4 controls the operating mode of the electronic device 1 by executing the program stored in the storage part (not illustrated) using a processor, such as a central processing unit (CPU ). Moreover, the CPU is a unit that is thought of as a concept including a microcomputer processing unit (MPU) or a microcomputer (MCU), and any of the functions, actions, and effects realized in the context of this invention can also be using such elements.
The main control part 4 obtains a control output by the communication part 10, and controls the corresponding transmission circuit WR as a function of the command obtained. In the case where the main control part 4 obtains an instruction to manipulate the needle of a second, in a transmission circuit WRa, the main control part 4 changes the level of the signal by passing it from a level lying below a threshold value (in what follows, we will refer to this level as the low level (L)) at a level equal to or greater than this threshold value (in what follows, we refer to this level as the high level (H)) for a predetermined period of time. On the other hand, the main control part 4 can change the signal level by going from the high level H to the low level B for a predetermined period of time. In any case, by detecting whether the level exceeds the predetermined threshold value or not, any change from low level L to high level H or change from high level H to low level L is detected.
In the case where the main control part 4 obtains the instruction to drive the needle at a predetermined angle forward (in the direction of clockwise), the main control part 4 changes the level of the transmission circuit WRb from low level L to high level H for a predetermined period of time. In the case where the main control part 4 obtains the instruction to drive the needle at a predetermined angle in the opposite direction (counterclockwise), the main control part 4 changes the level. of the transmission circuit WRc from the low level L to the high level H. In the case where the main control part 4 obtains the instruction to perform a countdown of one second (manipulate the needle by less than one second) in taking the current time as a reference, the main control part 4 changes the level of the transmission circuit WRd from the low level L to the high level H. In the case where the main control part 4 obtains the instruction to operate the pointer continuously, the main control part 4 changes the level of the transmission circuit WRe from the low level L to the high level H for a predetermined duration. In the case where the main control part 4 obtains the instruction to stop the manipulation of the needle by plus or minus one second, the main control part 4 changes the level of the transmission circuit WRf from the low level L to the level H. Furthermore, in this embodiment, the signal outputted to the control portion 56 by the main control portion 4 is also referred to as an instruction signal. Moreover, according to this embodiment, any of the instruction signals outputted by the transmission circuits WRa to WRf, is a "first instruction signal", at least one of the instruction signals. remaining is a "second instructional signal".
Thus, according to this embodiment, the main control part 4 controls the first driving unit of a needle 5 only by changing the signal level of the corresponding transmission circuit WR from the low level L to the high level H in accordance with FIG. the command instruction sent by the terminal 20 which constitutes the external device.
Furthermore, in the instruction signal, a signal parameter, such as an amplitude (signal level), a pulse, a pulse width, a duty cycle, a frequency, or the number pulses may vary in each transmission circuit WR, or the signal parameters may be the same regardless of the type of transmission circuit WR on which they are delivered. The signal parameter in the instruction signal is an index that indicates an example of "pulse characteristics". Moreover, without being limited to a rectangular pulse signal, the pulse signal can be triangular, sawtooth, sinusoidal, or take the form of a single pulse (as for example when measuring the pulse ).
Moreover, in the case where the communication portion 10 receives information continuously from the terminal 20, the main control part 4 outputs the instruction signal output to the transmission circuit WR in order of reception.
The first needle driving unit 5 comprises the support 51, an inlet 52, an oscillation circuit 54, a storage part 55, the control part 56, a first motor 57, and a first needle 58. Furthermore, it can also be envisaged, according to another aspect of the invention, that the first needle 58 can be fixed outside the first needle motor unit 5.
The support 51 comprises the substrate, a base plate which constitutes a base, and a receiving plate which removes a component disposed on the base plate from the opposite side, another housing part, a bearing on which a rotary shaft of the first motor 57 is linked, or the like. The substrate is disposed on the base plate, and on the substrate, a wiring, the input 52, the oscillation circuit 54, the storage part 55, the control part 56, the first motor 57, a gear which is a gear train transmitting engine torque, etc. are arranged. One unit is assembled by attaching the components using the receiving plate. Furthermore, on the base plate is disposed an electrode which serves as a terminal connection - which will be described later - and the electrode plays the role of creating an electronic component inside and outside the body. unit electrically connected to each other.
The input 52 is a communication interface of the control part 56. The input 52 comprises a first port 52a which is connected to the transmission circuit WRa, a second port 52b which is connected to the transmission circuit WRb, a third port 52c which is connected to the transmission circuit WRc, a fourth port 52d which is connected to the transmission circuit WRd, a fifth port 52e which is connected to the transmission circuit WRe, and a sixth port 52f which is connected to the transmission circuit WRf transmission. According to the example illustrated in FIG. 1, each port of the input 52 is arranged such that it is separated from the support 51 where the control portion 56 is installed, but the present invention is not limited to such a configuation. Each port of the input 52 may be configured as a socket on a physical layer within the control portion 56, or may be an input or output port of a virtual signal, which is consisting of each take of the physical layer and the transmission circuit WR. On the other hand, all the ports between the first port 52a and the sixth port 52f are examples of "first entry", and another port is an example of "second entry".
The oscillation circuit 54 comprises, for example, the crystal resonator of 32.768 kHz, and divides (with a division factor of 1 / n) the signal generated by the crystal resonator, generates the reference signal for driving the first needle, and outputting a reference signal generated at the control portion 56. For example, the oscillation circuit 54 generates the reference signal of 1 Hz (n = 1). Moreover, the oscillation circuit 54 receives the commands from the control part 56, changes the division factor, and generates the reference signal. For example, the oscillation circuit 54 changes division factor, and generates a reference signal of 64 Hz (n = 64). In addition, the reference signal is similar to a clock signal.
The first motor 57 is a stepping motor, and is rotated as a function of the drive signal output by the control part 56. The first needle 58 kept rotatable by the rotary shaft ( not shown) of the first motor 57. The first needle 58 is supported by a bearing included in the carrier 51, and is rotated relative to the carrier 51 in accordance with the rotation and driving of the first motor 57.
The storage portion 55 can be performed using a non-volatile storage means, such as a ROM (ROM) or a flash memory. The storage portion 55 contains the program executed by the processor, and furthermore may also contain a drive signal correspondence table 55a which will be described later, a drive signal generating table 55b SIG_E, etc. The drive signal correspondence table 55a and the drive signal generating table 55b SIG_E are examples of a "look-up table".
The control part 56 can be made using hardware, such as a wide integration integrated circuit (LSI), a specific application integrated circuit (ÂSIC), or a programmable gate array ( FPGA). With reference to the drive signal correspondence table 55a housed in the storage portion 55, the control portion 56 generates the drive signal to drive the first motor 57 in accordance with the type of input port 52 in which the instruction signal is introduced from the main control part 4. Moreover, the control part 56 outputs the drive signal generated to the first motor 57.
Furthermore, the control portion 56 outputs a drive signal at the time of raising or lowering, that is to say respectively the rise and fall of the signal delivered by the party. main control 4. The control part 56 compares the predetermined threshold value with the signal, detects a signal increase or a signal decrease based on the result of this comparison, and delivers the drive signal at the time of this detection .
FIG. 2 is a view illustrating an exemplary drive signal map table 55a stored by the storage portion 55. As illustrated in this example, in the drive signal correspondence table 55a, each port type is correlated with an operative pattern of the needle and the drive signal for driving the needle according to this operative pattern. For example, in the first port 52a, a "one-second needle manipulation" operating pattern is correlated with a SIG_A drive signal. In other words, the drive signal correspondence table 55a is a table in which the correspondence relation between the control operation of the first port 52a, which constitutes the input, and the first hand 58, is saved. and the drive signal of the first motor 57 which drives the first needle 58.
In what follows, we describe the operation of the control portion 56 in the case where the instruction signal is introduced in each of the ports. In the case where the instruction signal introduced at the input of the first port 52a, the control part 56 generates the drive signal SIG_A to manipulate the first needle 58 in the clockwise direction every second, in using the frequency (for example, 1 Hz) of the reference signal generated by the oscillation circuit 54. Moreover, the control part 56 outputs the drive signal SIG_A generated to the first motor 57, and results in rotating the first needle 58 clockwise 6 degrees every second.
Furthermore, in the case where the instruction signal is introduced at the second port 52b, the control part 56 generates a drive signal SIGJ3 to rotate the first needle 58 in the direction of the needles. a watch at a predetermined angle (e.g., 60 degrees) using the frequency of the reference signal generated by the oscillation circuit 54. Furthermore, the control portion 56 outputs the drive signal SIG_B generated at the first motor 57, and rotates the first needle 58 in a clockwise direction at a predetermined angle.
Furthermore, in the case where the instruction signal is introduced at the third port 52c, the control portion 56 generates a drive signal SIG_C to rotate the first needle 58 in the opposite direction of the needles d a watch at a predetermined angle (e.g., 60 degrees) using the frequency of the reference signal generated by the oscillation circuit 54. Furthermore, the control portion 56 outputs the drive signal SIG_C generated at the first motor 57, and rotates the first needle 58 counterclockwise at a predetermined angle.
Furthermore, in the case where the instruction signal is introduced at the fourth port 52d, the control portion 56 generates a drive signal SIG_D to manipulate the first needle 58 in the opposite direction of the needles. a watch every second using the frequency of the reference signal generated by the oscillation circuit 54. Furthermore, the control portion 56 outputs the drive signal SIG_D generated to the first motor 57, and drives in rotation the first needle 58 counter-clockwise 6 degrees every second.
Furthermore, in the case where the instruction signal is introduced at the fifth port 52e, the control portion 56 changes the division factor of the oscillation circuit 54 and generates a drive signal SIG_E to perform a continuous operation with respect to the first needle 58 using the frequency (e.g., 64 Hz) of the reference signal that is generated by the oscillation circuit 54, whose division factor has been changed.
The predetermined continuous operation may consist, for example, in a series of operations performed by the needle independently of the measurement of time. Since the instruction signal is introduced into the fifth port 52e by the main control part 4 so that the terminal 20 receives a message or notification to the user of a reminder or the like using the electronic device 1, the control portion 56 can perform the series of operations of the needle which is unrelated to the measurement of time, and can attract the user's attention by rotating the needle in the direction of the clockwise or anti-clockwise by several degrees for several seconds, or by rotating the needle irregularly. The actuation of the needle is effected by delivering, continuously or intermittently, a series of drive signals which can each control the contents of the first motor 57. For example, the control part 56 generates the series of signals drive with reference to the drive signal SIG_E of the generation table 55b saved in the storage part 55.
Furthermore, in the case where the instruction signal is introduced at the sixth port 52f, the control portion 56 generates a drive signal SIG_F to stop the operation of the manipulation of the first needle 58 in clockwise or anticlockwise each second using the frequency of the reference signal generated by the oscillation circuit 54. Furthermore, the control portion 56 outputs the signal SIG_F drive generated at the first motor 57, and stops the drive of the first needle 58.
FIG. 3 is a view illustrating an example of generation table 55b SIG_E drive signal stored in the storage portion 55. As shown in FIG. 3, each control item illustrating control contents is correlated with a slot number (in Fig. 3, "slot number") and frequency. The slot number indicates a processing order. In the control section you can find, for example, a drive speed (in Fig. 3, the needle drive speed) of the needle, the direction of rotation of the needle (in fig. 3, the direction of rotation), the angle of rotation of the needle (in Fig. 3, the angle of rotation), the position in which the actuation in rotation of the needle is started (on the figures, the starting position), and information (in Fig. 3, the possibility of a back and forth motion) indicating whether the direction of rotation can be reversed and whether the rotation is performed according to a regular rotation angle. The control items are each correlated respectively with a slot number, and the control portion 56 generates the drive signal according to the contents of the control items for each slot number. At this time, the control portion 56 generates the drive signal at a given frequency (e.g., 64 Hz), correlated with the control topic. Furthermore, the control part 56 sequentially outputs N drive signals which are respectively correlated to each slot number 1 to N, for example, to the first motor 57 according to an order starting from the smallest of the corresponding slot numbers. An assembly formed of a series of N drive signals corresponds to the drive signal SIG_E. In other words, the drive signal generating table 55b SIG_E is a table in which is stored a correspondence relation between an actuating operation of the first hand 58 and a driving force for driving the first motor 57 in accordance with this operation operation.
FIG. 4 is a view illustrating an example of a continuous operation of the first needle 58 rotated by the drive signal SIGJE. The drive signal SIG_E (a series of drive signals) generated using the drive signal generating table 55b SIG_E, for example, is a signal for controlling the first motor 57 so that the first hand 58 moves back and forth according to a predetermined rotation angle of amplitude 9 (for example, at an amplitude ranging from 10 hours to 2 hours on the dial), as illustrated in FIG. 4. The control part 56 delivers the drive signal SIG_E to the first motor 57, and controls the driving of the first needle 58 as illustrated in FIG. 4. On the other hand, the control part 56 can control the first needle 58 in a clockwise direction in an irregular drive, for example 30 degrees, 60 degrees, then again 30 degrees, etc., as than other continuous mode of operation for the first needle 58.
FIG. 5 is a state diagram illustrating an exemplary processing flow of the control portion 56 according to the first embodiment. The processing of the state diagram may, for example, be carried out repeatedly in a cycle of 1 Hz.
First, the control portion 56 successively obtains instruction signal levels from the first to the fourth ports. On the other hand, the control portion 56 obtains the instruction signal level in an order from the first port to the fourth port. Then, the control portion 56 determines whether the instruction signal level of any of the ports, i.e., the first to the fourth port, has reached the high level H (step S 100). In the case where the level of the instruction signal of one of the first to the fourth port is at the high level H (step S 100; YES), then the control portion 56 determines whether the instruction signal level of another port different from that whose instruction signal level is at the level H, also has the level H (step S 102).
In the case where it has been determined that the instruction signal level of none of the ports taken between the first and fourth ports has reached the high level H (step S 100; NO), or if it is determined that the instruction signal level of two or more ports is high, has reached the H level (step S 102; YES), the control portion 56 ends the processing of the state diagram without generating drive signal. On the other hand, in the case where the control part 56 and the main control part 4 are provided with a seventh port (not shown), the control part 56, for example, can deliver an error signal to the part control master 4 as a response to the command instruction.
However, in the case where it is determined that the instruction signal level of only one of the ports is at the high level H (step S 102; NO), then the control portion 56 generates a signal d GIS drive which corresponds to the port in which the instruction signal has been introduced, with reference to the drive signal correspondence table 55a (step S 104).
Then, the control portion 56 delivers the GIS drive signal generated at the output to the first motor 57 (step S 106). Once this is done, the processing of the state diagram is completed.
FIG. 6 is a state diagram illustrating another example of a processing flow of the control portion 56 according to the first embodiment. The processing of the state diagram can be repeated, for example, in cycles of 1 Hz.
First of all, the control part 56 determines whether the level of the instruction signal of the fifth terminal port 52e has reached yes or no the high level H (step S 200). In the case where the level of the instruction signal of the fifth port 52e is at the level H (step S 200; YES), then the control portion 56 determines whether the level of the instruction signal of another port different from the fifth Terminal port 52e in which the instruction signal is introduced is at level H (step S 202).
In the case where the level of the instruction signal of the fifth port 52e is not at the level H (step S 200; NO), or in the case where the level of the instruction signal of the plurality of ports is at the H level (step S 202; YES), the control portion 56 terminates the processing of the state diagram.
Nevertheless, in the case where only the level of the instruction signal of the fifth port 52e is at the level H (step S 202; NO), the control part 56 changes the division factor of the oscillation circuit 54 ( step S 204). Then, the control portion 56 generates N drive signals (drive signal SIG_E) which is respectively correlated to each of the slot numbers 1 to N, using the frequency of the reference signal generated by the oscillation circuit 54 whose division factor has been changed (step S 206).
Next, the control portion 56 outputs N generated drive signals as a SIGJE drive signal to the first motor 57 in an order ranging from the smallest slot number to the largest, or vice versa ( step S 208). After that, the processing of the state diagram is completed.
Moreover, according to the example illustrated in FIG. 6, the drive signal is generated when the level of the signal introduced at the control portion 56 changes from the low level to the high level, but the control portion 56 can generate the driving force when the signal level entry is changed from high to low.
FIG. 7 is a view illustrating an exemplary drive signal output from the control portion 56. In FIG. 7, a horizontal axis illustrates, for example, an instant "t", and a vertical axis illustrates, for example, a signal level. For example, the control portion 56 outputs a signal of several triangular shapes repeated in a cycle of 1 Hz frequency, which constitutes the drive signal SIG_A. Furthermore, the control portion 56 outputs a single triangular signal, also repeated in a cycle of 1 Hz frequency as a drive signal SIG_B · Furthermore, the control portion 56 outputs a signal of which the polarity is inverted with respect to the drive signal SIGJ3, constituting the drive signal SIG_C. Moreover, the control part 56 outputs a signal in which the polarity is inverted with respect to the drive signal SIG_A, forming the drive signal SIG_D. Furthermore, the control portion 56 outputs the drive signal SIG_E, whose drive signals generated in accordance with the control contents of each slot are continuous with respect to each other. On the other hand, the control part 56 outputs the drive signal SIG_F as a signal obtained by making the signal level of the drive signal SIG_A or the drive signal SIG_D at the low level L (for example, 0 ) during the entire period of time considered.
According to the first embodiment described above, by providing the input 52 with a plurality of ports in which the instruction signal is introduced from the main control part 4, and the control part 56 which outputting the drive signal which corresponds to the type of port in which the instruction signal is introduced, to the first motor 57, it is possible, in the case where the instruction signal is introduced in any of the plurality of ports, to ensure that the instruction signal outputted to the control part 56 included in the first needle driving unit 5 of the main control part 4 takes the form of a simple signal , and in order to determine the port (transmission circuit WR) of an instruction signal output destination in accordance with the information of the terminal 20, it is possible to easily control the driving of the needle of the timepiece by the stepper motor.
Furthermore, according to the first embodiment, the program which is used by the processor of the main control part 4 can be implemented as a simple program which determines the port (transmission circuit WR) of the instruction signal. according to the information sent by the terminal 20, and outputs the instruction signal to the first driving unit of a needle 5 via the transmission circuit WR and the port. Therefore, it is not necessary for the creator of the program to interpret engine characteristics of a drive signal generation method, and for example, it is sufficient to create only a simple program in which the main part control 4 only outputs the instruction signal to any of the ports selected between the first 52a and the sixth 52f. Therefore, according to the first embodiment, it is possible to reduce the load relative to the creation of the program.

Furthermore, the actuation and operation of each unit described above are given by way of example, without the present invention limiting them.
The main control part 4 controls the corresponding transmission circuit WR according to the command instruction received by the terminal 20. At this time, the main control part 4 changes the signal parameter of the signal instruction which is transmitted on the transmission circuit WR, and assigns a target value (control target) controlled by the control part 56 within each motor of the first needle driving unit 5A, the second driving unit of the needle 6, and the third needle drive unit 7, and the notification portion 89 of the additional unit 8. The main control portion 4 assigns the number of control targets, for example, in accordance with the number of signal pulses. instruction that is outputted during a predetermined period of time.
The control part 56 determines the control target based on the signal parameter of the instruction signal which is transmitted on the transmission circuit WR when the main control part 4 controls the transmission circuit WR.
FIG. 9 is a view schematically illustrating an exemplary method of determining the control target by the control portion 56. In FIG. 9, the horizontal axis illustrates, for example, the time "t", and the vertical axis illustrates, for example, a signal level. As illustrated in FIG. 9, for example, in the case where the number of pulses of the instruction signal which is outputted during a predetermined period of time is equal to 1, the control portion 56 drives the first motor 57A of the first power unit needle 5A, and in the case where the number of pulses of the instruction signal is equal to 2, the control portion 56 drives the second motor 57B of the first needle driving unit 5A. On the other hand, in the case where the number of pulses of the instruction signal is equal to 3, the control part 56 drives the third motor 67 of the second needle motor unit 6, and in the case where the number of instruction signal pulses is 4, the control portion 56 drives the fourth motor 77 of the third needle motor unit 7. Moreover, in the case where the pulse width of the instruction signal is equal to or greater than the norm (for example, 2 times), then the control part 56 causes the notification part 89.
Moreover, a method of allocating the control target (different engines, and the notification portion 89) is an example, and the control target can be assigned by the frequency or the duty cycle. Fig. 10 is a view schematically illustrating another example of a method of determining the control target by the control portion 56. In FIG. 10, the horizontal axis illustrates, for example, the time "t", and the vertical axis illustrates, for example, the signal level. As illustrated in FIG. 10, for example, in the case where the duty ratio (= A / B) is equal to or greater than a predetermined value (for example, 0.5), the control portion 56 can drive the first motor 57A by outputting the signal of drive to the first motor 57A, and in the case where the duty cycle (= A / B) is less than a predetermined value, the control portion 56 can drive the second motor 57B by outputting the drive signal to the second 57B engine.
Moreover, according to the example described above, a single control target is allocated according to the instruction signal; nevertheless the present invention is not limited to such an example. For example, in the case where the instruction signal is a signal which indicates a predetermined number of bits (for example 3 bits), the pulse rise is detected for each cycle using the moment of the rise of the first pulse as reference, and the number of canceled targets can be assigned by binary codes where the rise of the pulse is equal to "1" and the descent equal to "0". For example, in the case where the binary code represented by the instruction signal is "011", the control part 56 drives 3 control targets simultaneously.
In the case where the plurality of control targets are assigned simultaneously, the control portion 56 can output the drive signal to all control targets. For example, in the case where the first motor 57A, the second motor 57B, and the third motor 67 are assigned to the instruction signal introduced into the first port 52a, the control part 56 outputs the drive signal SIG_A which corresponds to the first port 52a to the 3 command targets. Thus, the electronic device 1 drives the first needle 58A, the second needle 58B, and the third needle 68 by the same operation.
FIG. 11 is a state diagram illustrating an exemplary processing flow of the control portion 56 according to the second embodiment. The processing of the state diagram can be done repeatedly, for example, at a frequency of 1 Hz.
First of all, the control part 56 can perform processing steps similar to the processing steps S 100 to S 104 of the state diagram illustrated in FIG. 5 described above. Then, the control portion 56 determines a control target that outputs the generated GIS drive signal based on the signal parameter of the instruction signal (step S 308). Then, the control portion 56 performs a similar processing step in the processing step S 106 of the state diagram illustrated in FIG. 5 previously described. Once this is done, the processing of the state diagram is completed.
FIG. 12 is a state diagram illustrating another example of a processing flow of the control portion 56 according to the second embodiment. The processing of the state diagram can be done repeatedly, for example, at a frequency of 1 Hz.
First of all, the control part 56 can perform processing steps similar to the processing steps S 200 to S 206 of the state diagram illustrated in FIG. 6 previously described. Then, the control portion 56 determines a control target that outputs the generated SIGJE drive signal based on the signal parameter of the instruction signal (step S 410). Then, the control portion 56 performs a similar processing step in the processing step S 208 of the state diagram illustrated in FIG. 6 previously described. Once this is done, the processing of the state diagram is completed.
Moreover, according to the example illustrated in FIGS. 11 and 12, the drive signal is generated when the level of the input signal introduced into the control portion 56 changes from low to high, however, the control portion 56 could also generate the drive signal. when the input signal level changes from high to low.
Moreover, in the case where the instruction signal level of the first port 52a is the high level H, the control portion 56 outputs the drive signal SIG_A to the third motor 67 of the second power unit. needle 6, and controls the third needle 68 for one-second needle manipulation. At this time, the control portion 56 controls the third hand 68, counts the number of seconds based on the reference signal, and can control the first hand 58A of the first hand drive unit 5A when 60 seconds have elapsed. elongated to drive the needle for one second.
According to the second embodiment described above, similarly to the first embodiment, the instruction signal outputted to the control part 56 included in the first needle driving unit 5A from the main part of control 4 can be a simple signal, the port (transmission circuit WR) of the output destination of the instruction signal is determined according to the information of the terminal 20, and thus, it is possible to control and control easily the driving the timepiece needle by the stepper motor.
Furthermore, according to the second embodiment, according to the instruction signal outputted by the main control part 4, the control part 56 can drive the control target (the engine or the notification part). other units connected to the first needle drive unit 5A. Therefore, according to the second embodiment, it is possible to satisfy the size reduction constraints of the unit, and simultaneously to ensure good control of the operation of the unit in the case where it is complicated. .
Furthermore, according to the second embodiment, in the case where the electronic device 1 is equipped with a plurality of units, since the control part 56 generates and outputs the drive signal for each unit. , it is possible to reduce the processing load of the main control part 4 which performs the communications processing with the terminal 20.
[0092] (Example of a second modified embodiment) In the following, an example of a second modified embodiment will be described. According to this second modified embodiment, according to the port whose instruction signal level is controlled at the level H, the control target to which the drive signal is output is determined in advance. The correspondence relation between each port and the control target can be stored as a drive signal correspondence table 55a in advance, or can be determined based on the command instruction sent by the terminal 20 .
The control part 56 determines the unit of the output destination of the drive signal generated with reference to the correspondence table 55a with the drive signal located in the storage part 55.
FIG. 13 is a view illustrating an example of a training signal correspondence table 55a stored in the storage portion 55 according to the second embodiment. As illustrated in FIG. 13, in the drive signal correspondence table 55a of the second embodiment, for each port type, the operation pattern of the needle, the drive signal, and the signal output destination of training are correlated with each other. For example, in the first port 52a, "the handling of the one-second hand", which is the operating reason for operation, the drive signal SIG_A, and the "first needle driving unit" which is the output destination, are correlated to each other.
In what follows, we will describe the operation of the control part 56 in the case where the instruction signal is introduced into each port. As illustrated in FIG. 3, the drive signals SIG_A and SIG_B are output to the control target (the first motor 57A and the second motor 57B) arranged on the first drive motor unit 5A, while the drive signal SIG_C is outputted to the control target (third motor 67) arranged on the second driving motor unit 6, the driving signal SIG_D is output to the control target (fourth motor 77) arranged on the third driving unit 7, the SIGJE drive signal is output to the control target (notification portion 89) arranged on the additional unit 8, and the drive signal SIG_F is output to the control target (The first motor 57A and the second motor 57B) arranged on the first driving motor unit 5A. The notification part 89 generates the audible alarm in accordance with the drive signal SIG_E, and notifies the user of the reception of the mail by the terminal 20 or the presence or the absence of a reminder.
Furthermore, the control part 56 can also output the same drive signal with respect to other units, in addition to the unit determined with reference to the drive signal correspondence table 55a. . For example, the control portion 56 outputs the drive signals SIG_A and SIG_B to the control target (the first motor 57A and the second motor 57B) arranged on the first drive motor unit 5A, and can output output the drive signals SIG_A and SIG_B to the control target (third motor 67) arranged on the second driving motor unit 6, and the control target (fourth motor 77) arranged on the third driving motor unit 7 .

Furthermore, each port of the input 52B may be provided with a tap on the physical layer inside the control part 56, may consist of an input and output port of a virtual signal consisting of each take of the physical layer and the transmission circuit WR. Furthermore, the transmission circuit CLK is a clock output provided from the main control part 4. In other words, according to this embodiment and as illustrated in FIG. 14, the first needle driving unit 5B is not equipped with the oscillation circuit, and the clock which is output from the main control part 4 is obtained and used.
The first motor 57A, the second motor 57B, and the third motor 57C are, for example, stepper motors. The first motor 57A, the second motor 57B, and the third motor 57C are rotated based on the drive signal output from the control portion 56. The first needle 58A is rotatably held by the bearing included in FIG. the support 51 B, and driven in rotation relative to the support 51B in accordance with the rotation and driving of the first motor 57A. The second needle 58B is kept mobile in rotation by the bearing included in the support 51 B, and rotated relative to the support 51B in accordance with the rotation and driving of the second motor 57B. Furthermore, a third needle 58C is held rotatably by the bearing in the support 51 B, and rotated relative to the support 51B in accordance with the rotation and drive of the third motor 57C. For example, the first needle 58A is a second hand, the second hand 58B is a minute hand, and the third hand 58C is an hour hand. On the other hand, there are also cases according to an aspect of the present invention wherein the first needle 58A, the second needle 58B, and the third needle 58C are made attached to the outside of the first needle motor unit 5B.
The control part 56 determines the unit of the output destination of the generated drive signal, for example with reference to the drive signal correspondence table 55a disposed in the storage part 55.
Furthermore, according to this embodiment, the first needle driving unit 5B is not equipped with the oscillation circuit, and it is supplied with the clock signal from the main control part 4.
[0106] FIG. 15 is a view illustrating an exemplary drive signal correspondence table 55a saved in the storage portion 55 according to the third embodiment. As illustrated in FIG. 15, in the drive signal correspondence table 55a, there is a correlation between each port type, the operational operating pattern of the hand, the training signal, and the output destination of the training signal. . For example, in the first port 52a, "a normal rotation of the first hand" which is the operating operational reason, the drive signal SIG_A, and the first motor which is the output destination, are mutually correlated, and at the level of the fourth terminal port 52d, "a rotation in the opposite direction of the second hand" which is the operational reason for operation, the drive signal SIG_D, and the second motor which is the output destination, are mutually correlated the one to another.
In what follows, we will describe the operation of the control part 56 in the case where the instruction signal is introduced into each port.
As illustrated in FIG. 15, the drive signals SIG_A and SIG_B are supplied to the first motor 57A which is the control target. The drive signals SIG_C and SIG_D are output to the second motor 57B which is the control target. The drive signals SIG_E and SIG_F are output to the third motor 57C which is the control target.
In this way, in the first needle driving unit 5B of this embodiment, the input 52B comprises the first port 52a (first input) in which the signal which normally drives in rotation (first operation) the first motor 57A is introduced, the second port 52b (second input) in which the signal drives in rotation in the opposite direction (second operation) the first motor 57A is introduced, the third port 52c (third input) in which the signal which normally drives in rotation (third operation) the second motor 57B is introduced, the fourth port 52d (fourth input) in which the signal which rotates in the reverse direction (fourth operation) the second motor 57B is introduced, the fifth port 52nd (fifth input) in which the signal which normally drives in rotation (fifth operation) the third motor 57C is introduced, and the sixth port 52f (sixth in in which the reverse drive signal (sixth operation) of the third motor 57C is introduced.

Furthermore, the control portion 56 generates the drive signal in accordance with the signal outputted by the main control part 4, and outputs the drive signal generated from the first motor 57A to the corresponding third motor 57C. . For example, in the case where the main control part 4 changes the level of the transmission circuit WRb from the low level to the high level, the control part 56 drives the first motor 57A in rotation in the opposite direction. On the other hand, the drive signal which normally drives the first motor 57A in rotation is a first drive signal, and the drive signal which rotates the first motor 57A in the opposite direction is a second drive signal. The drive signal that rotates the second motor 57B is a third drive signal, and the drive signal that rotates the second motor 57B in the opposite direction is a fourth drive signal. The drive signal that normally drives the third motor 57C to rotate is a fifth drive signal, and the drive signal that rotates the third motor 57C in the opposite direction is a sixth drive signal. On the other hand, the instruction signal which normally drives the first motor 57A in rotation is a first instruction signal, and the instruction signal which rotates the first motor 57A in the opposite direction is a second instruction signal. The instruction signal which normally drives the second motor 57B in rotation is a third instruction signal, and the instruction signal which rotates the second motor 57B in the opposite direction is a second instruction signal. The instruction signal which normally drives the third motor 57C in rotation is a fifth instruction signal, and the instruction signal which rotates the third motor 57C in the opposite direction is a sixth instruction signal. The storage part 55 saves the correspondence relation between each of the inputs 52 (the nth entry, where "n" is an integer ranging from 1 to 6), each drive signal, and the output destination, as illustrated in FIG. fig. 15.
In what follows, we will describe an example of a relationship between the clock input introduced into the control portion 56 and the drive signal.
[0112] FIG. 16 is a view illustrating an example of the relationship between the clock signal input to the control portion 56 and the drive signal, according to this embodiment. In fig. 16, the horizontal axis shows the time, and the vertical axis shows a signal level. Moreover, the signal form g11 is a form of SIG_CLK clock signal outputted by the main control part 4. The signal form g12 is a signal form corresponding to the signal delivered to the transmission circuit WRa by the party main control 4, and the signal form g13 is a form of drive signal SIG_A. A signal form g14 is a signal form corresponding to the signal outputted to the transmission circuit WRb by the main control part 4, and a signal form g15 is a form of a training signal SIG_B · [0113] Has a instant "t1", identical for the signal form g11 and the signal form g12, which corresponds to the moment when the clock signal SIG_CLK rises, the control part 56 compares the level of the transmission circuit output with the transmission circuit WRa by the main control part 4 with the predetermined threshold value, and detects that the signal level has changed from the low level to the high level. Moreover, at this moment "t1", after the main control part 4 has made the determination of the signal level, the control part 56 outputs the drive signal SIG_A to the first motor 57A, similarly to the form signal g13. Moreover, in the example illustrated in FIG. 16, the drive signal SIG_A is outputted between the instant "t1" and the instant "t2"; however the drive signal SIG_A could be a signal which drives the first needle 58A at a predetermined angle. Moreover, the example illustrated in FIG. 15 is an example that the number of normal rotations is 1; however, this number of normal rotations is not limited to this number and could be a number corresponding to a particular usage.
At the instant "t3", at the time of raising the clock signal SIG_CLK similarly to the signal form g11 and the signal form g14, the control part 56 compares the level of the transmission circuit delivered at the output to the transmission circuit WRb by the main control part 4 with the predetermined threshold value, and detects that the signal level has changed from the low level to the high level. Moreover, at this moment "t3", after the main control part 4 has made the determination of the signal level, the control part 56 outputs the drive signal SIG_B to the first motor 57A, similarly to the shape signal g15. Moreover, according to the example illustrated in FIG. 16, the drive signal SIG_A is outputted between times "t3" and "t4", but the drive signal SIG_B could be a signal that drives the first needle 58A at a predetermined angle. Moreover, the example illustrated in FIG. 15 is an example in which the number of inverse rotations is 1; however, this number of inverse rotations is not limited to this number and could correspond to a number corresponding to a particular use.
Moreover, according to the example illustrated in FIG. 16, the drive signal is generated when the input signal level introduced into the control portion 56 changes from the low level to the high level, but the control portion 56 could also generate the drive signal when the input signal goes inversely from high level to low level.
For example, at the instant "t4", at the time of the descent of the clock signal SIG_CLK, similarly to the signal form g11 and the signal form g14, the control part 56 compares the level of the circuit transmission circuit outputted to the transmission circuit WRb by the main control part 4 with the predetermined threshold value, and can detect that the level of the signal changes from the high level to the low level. On the other hand, at the instant "t4", after the main control part 4 has made this signal level determination, the control part 56 can output the drive signal SIG_B at the output to the first motor 57A, similarly to the signal form g16.
Moreover, when the SIG_CLK clock signal output by the main control part 4 continues to be high or low for a period of time which is equal to or greater than a predetermined period of time , the control part 56 determines that the input of the clock signal is stopped. In the case where it is determined that the input of the clock signal is stopped, the control part 56 switches each part of the first needle driving unit 5B into a power saving mode (standby mode). . On the other hand, when the clock signal SIG_CLK is again at the high level or at the low level, the control part 56 commands these parts to go out of the standby mode.
In other words, the main control part 4 can switch the first needle driving unit 5B into the energy saving mode by stopping the clock signal supplied to the control part 56.
In the following, we will describe an example of treatment of the control part 56.
FIG. 17 is a state diagram illustrating an example flow of the processing of the control portion 56 according to this embodiment. The processing of the state diagram is carried out repeatedly, for example, at a frequency of 1 Hz (that is to say in cycles of 1 Hz).
First, the control portion 56 detects the level of each instruction signal from the first port 52a to the sixth port 52f (step S 500).
Then, the control part 56 compares the signal level of each detected port with the predetermined threshold value, and determines whether or not the instruction signal output by the main control part 4 has changed in accordance with to the result of the comparison (step S 501).
In the case where it is determined that the instruction signal output by the main control part 4 has not changed (step S 501; NO), the control part 56 returns to the step of S 500 treatment.
In the case where it is determined that the instruction signal output by the main control part 4 has been changed (step S 501; YES), the control part 56 generates the drive signal with reference to the correspondence table stored in the storage part 55, with respect to the engine which corresponds to the terminal port whose level has changed. Then, the control part 56 outputs the drive signal generated in the engine which corresponds to the terminal port with reference to the table saved in the storage part 55 (step S 502).
In the foregoing, various embodiments have been described for the present invention, but the present invention is not limited thereto, and it is possible to add various changes in a range that does not go beyond the scope of the present invention. the present invention.
Moreover, the use of the present invention can be changed in different ways. For example, a smartphone (electronic device) carried by a user or the like may receive information relating to a vehicle speed, a rotational speed, or a remaining fuel level from a transceiver BLE apparatus driven by a machine internal combustion engine or engine and is loaded onto a vehicle, and can send a command to display the vehicle speed, rotational speed, or the amount of fuel remaining to an integrated circuit (IC) control (control part ) of the needle drive unit from a microcomputer (main control part) of the smart watch (also known as connected watch). Thus, the needle of the needle driving unit can display information relating to the speed of the vehicle or the like. Furthermore, it is also possible to directly mount the needle drive unit on an onboard type measuring instrument display part (within a panel of the instrument or the like).
