    Traffic light {SIGNALLING BEACON}
    [2] Known signal signs are equipped with illuminated spotlights, which are used to indicate temporary switching areas in public work areas, road workshops.
    [3] Generally, such beacon lights are powered from a generator, which are connected to each other by electric wires. Such beacon systems have a significant drawback of providing external power to the beacons. Conventional generators are quite large and cause difficulty in moving the generator. On the other hand, if a break occurs in any of the wires, either by itself or by other factors, the problem is that all of the signal lights in the set are powered off.
    [4] Other known beacon systems employ a battery for each beacon. This is to avoid the problem of wire shorts, but the battery has to be replaced regularly, which incurs significant costs. Moreover, each signal beacon must be individually switched on and off manually, which lacks control of the on / off switching, resulting in significant waste of time.
    [5] William Lane International Patent WO-9313984-A discloses a lighting system for an airport runway to assist in landing of an aircraft. The lighting system consists of an illumination spotlight, a battery, a solar cell and an antenna for detecting signal reception and switching the lamp. Moreover, the system is equipped with a photosensitive switch to ensure that the spotlight is not turned on during the day.
    [6] In International Patent WO-9205612-A of Ital Solar S.P.A, a lighting system for an airport is disclosed. The system consists of one or more photo-voltage modules, a battery, a charge regulator, a current supply and control module, one or more lighting spotlights, and a control and remote control unit. The current supply and control module is equipped with a microprocessor that controls the internal electrical behavior and the transmitter.
    [7] The Spanish patent No. 9400035 of Jose Jorva Gonzalez discloses a conical signal lamp which consists of an illuminated spotlight mounted in a hollow housing, the housing being fitted with a battery with a switching device. The conical traffic light also consists of a device for picking up solar cells and electromagnetic radiation. The switching device switches the spotlight when the pick-up device receives electromagnetic radiation emitted by the transmitter over a long distance.
    [8] All of the foregoing prior patents have serious disadvantages which will be described later.
    [9] Firstly, the devices of the prior patent have a significant disadvantage that they cannot be stored inoperable due to their structural or other functional reasons. This drawback means making it difficult to transport and install the devices.
    [10] Secondly, none of the above described devices can be extinguished on their own, which is consumable for all devices, which can lead to battery discharge even though small when not used, thus reducing independence.
    [11] On the other hand, due to the structure of the solar cell, the above-described devices have a problem in that the energy efficiency is very weak in relation to the required energy characteristics.
    [12] Finally, the devices of the preceding patents mentioned above are not universal, which means that they can only be used for a specific purpose and cannot be used for other purposes such as road markings or fences.
    [1] FIELD OF THE INVENTION The present invention relates to radio frequency controlled signal signs having a lighting spotlight and a photocell for powering internal circuitry.
    [34] 1 is an exploded perspective view of a signal sign that is the object of the present invention.
    [35] FIG. 2 is a block diagram of the signal indicator circuit of FIG. 1.
    [36] FIG. 3 shows an electronic circuit and a receiver-decoder circuit for controlling the lighting indicator of the signal indicator of FIG. 1.
    [37] 4 is an electronic circuit diagram of a transmitter-encoder as a signal marker of the present invention.
    [13] It is an object of the present invention to eliminate the disadvantages of the prior art described above and to provide a signal beacon with the advantages described below.
    [14] The signal beacon of the present invention is characterized in that the control circuit of the lighting indicator comprises a timer, a logic circuit for polarization of the lighting indicator and the timer, and a connection device for switching off the energy accumulator in case of storage.
    [15] In this way the signal beacon can be switched off automatically without storage at nominal energy consumption and is universal.
    [16] The photovoltaic cell is preferably composed of 16 identical cell elements connected in series to have a total surface area of at least 100 square meters, preferably 120 square meters.
    [17] Good energy efficiency is obtained with the power supply having the above structure, thereby providing a signal indicator lamp having more sufficient self-reliance for correct operation.
    [18] In accordance with a feature of the invention, the transmitter-radio frequency encoder circuit consists of an antenna, a transmitter, an encoder (encoder0, a plurality of microswitches and a drive resistor).
    [19] The transmitter-encoder circuit generates 9-bit rasters transmitted at radio frequency and contains data necessary for circuitry to control the operation of signal markers and the like.
    [20] The receiver-decoder circuit is preferably composed of an antenna, a receiver, a decoder, a plurality of switches and drive registers.
    [21] With this structure, a 9-bit raster transmitted at radio frequency is obtained by the transmitter-encoder and decoded so that it can be interpreted by the control circuit.
    [22] The illumination indicator is preferably composed of at least one brightly lit diode.
    [23] Depending on the use of the signal beacon of the present invention, the number and position of the light emitting diodes provided can be changed.
    [24] Moreover, the signal indicator lamp includes a support on which an energy accumulator is mounted.
    [25] The structure of the support can be adjusted differently to provide the versatility described above. Thus, it is possible to use signal signs in other states, such as at the ground, fence, or at the center dividing line of a road.
    [26] According to the present invention, the signal indicator lamp may include a radio detector inside the support.
    [27] The radio detector makes it possible to control the speed of the vehicle when a signal sign is used on the road.
    [28] In addition, the energy storage device is preferably a lead acid battery.
    [29] In addition, the frequency band of the signal transmitted by the transmitter-encoder circuit is 25-1,000 MHz, and it is important to have a potential of less than 10 mW.
    [30] In this way, it is possible to use a low-potential equipment for a limited use, which means that a signal sign can be used without permission in the frequency band.
    [31] The signal beacon has a rod, one end of which contacts the connecting device and the other end of which is the free end.
    [32] When the signal beacon is stored, the rod is activated by the cover of the signal beacon and does not operate the switch directly under the cover, thus interrupting the power supply to the signal beacon circuit.
    [33] DETAILED DESCRIPTION Hereinafter, an embodiment of the present invention will be described in more detail with reference to the accompanying drawings which are schematically shown for illustrative purposes only.
    [38] As shown in Fig. 1, the signal beacon 1 of the present invention includes a cover 2 for protecting the interior of the signal beacon, a photoelectric cell 3, and a signal beacon (as shown in Fig. 3). Printed circuit board 4 with associated circuits, diaphragm 5, casing 6, battery 7 for powering signal beacon 1 and supports 8 for signal beacon 1 It consists of.
    [39] The support 8 of the signal beacon 1 shown in this figure is conical in shape cut off at the top. In the present embodiment, the signal indicator lamp 1 can be used to generate a signal, for example, when it can occur on the road. The signal beacon 1 may be, for example, used as a boundary fence of a watch, a protective fence used on a road, or another type of support so as to be used in a central lane of a road.
    [40] Thanks to the versatility of the signal beacon 1 of the present invention, a signal beacon can be used wherever signal generation is required.
    [41] 2 shows a circuit block diagram of the signal beacon 1. The circuit comprises a photocell 3, a protection diode 10, a battery 7 for storing energy generated by the photocell 3, an electronic control and receiver-decoder circuit 4, and a plurality of lighting indicators 13. )
    [42] The photovoltaic cell 3 has an area of 120 square meters divided into 16 parts connected in series to obtain a circuit current of 200 mA and an open circuit strength of 9.2 V under standard lighting conditions. With this structure, an output value of a cell of 9 V and 200 mA can be obtained to obtain a good luminance of 800 W / square meter. All these data give better energy efficiency than is needed for use.
    [43] The protection diode 10 is a Schottky diode exhibiting a Vf of 0.32V.
    [44] The battery 7 is a 6 V, 5 Ah lead acid battery. It is also possible to use 6V, 4Ah batteries, but in this case the independence of the signal indicator 1 is reduced.
    [45] The illumination indicator 13 consists of six sets of high intensity light emitting diodes (LEDs). The color of the light emitting diode can vary, but red (635 nm), orange (618 nm), yellow (588 nm), lime green (570 nm) and green (560 nm) are noticeable. Such light emitting diodes exhibit luminous intensity between 10 and 25 cd when operating at a current of 20 mA.
    [46] As shown in Fig. 3, the electronic control circuit 14 with the illumination indicator 13 operates at a frequency of 1 Hz with a 91.5% operating cycle, so that the light-emitting diode 13 flashes and is stabilized periodically every second. With a CMOS 555 (15), the flash duration is 80 ms when the timer output is low potential. The control circuit 14 also includes a block 16 that performs the logic function of polarizing the timer 15 and the light emitting diode 13. The block 16 is constructed based on 74HC00, where only two 4 NAND ports 17 are used. The various inputs of the block 16 are the (bright light) light signal 18 and the tail light mode signal 19 and the signals 20 which mean no ambient light.
    [47] Signals 18 and 19 are obtained via radio frequency from transmitter-coder circuit 22, while signal 20 is the output voltage of photovoltaic cell 3 (signal 20 when cell 3 is in an illuminated state) ) Is high potential, i.e., while signal 20 is low, i.e., when cell 3 is off. The table below shows the (light / off) status of the light emitting diodes that make up part of the light indicator (13) according to the value of the input logic variable in block (16).
    [48] The electronic control circuit 14 includes a micro switch 23 such as an SPTD micro switch operated by a lever. The switch 23 is automatically operated by a rod (not shown in the figure) and has a function of turning off the power supply to the signal indicator lamp when the signal indicator lamp is stored. The rod is in contact with the switch 23 on the one hand and free on the other and is actuated by the lid 2 of the beacon 1 when storing the beacon.
    [49] The voltage input 24 is connected to the positive terminal of the battery 7 while the remaining elements form part of the configuration of the timer 15 and require precise operation without analysis.
    [50] The receiver-decoder control circuit 21 shown in FIG. 3 is adapted to receive and decode the signal transmitted by the electronic transmitter-encoder circuit 22. The control circuit is composed of an antenna 25, a receiving circuit 26, a decoder 27, a plurality of microswitches 28 and a driving register 29.
    [51] The antenna 25 is basically unipolar and the choice of radio-controlled operating range and simplicity of design should be taken into account.
    [52] Receiver 26 allows a wideband pulse modulation design as the RFM, ASH receiver, of the RX1005. The receiver has very low power consumption and does not require any permission and has great versatility in encoding / decoding information.
    [53] The decoder 27 is a motor-roller MC45027, and can interpret the information supplied by the electronic transmitter-encoder circuit 22 as an integrated circuit of CMOS low power consumption. The information consists of a 9-bit raster, the first 5-bits of which are address bits, allowing trinary encoding of 243 different addresses and binary encoding of 32, and 4 remaining bits. Are data bits, one of which is for signal 18 and the other for signal 19.
    [54] The microswitch 28 is used to assign an address (with one bit for one microswitch) to the five bits described above, while the drive register 29 is at a high level for each of the decoder address inputs 27. Or allow selection among low levels.
    [55] 4 shows an electronic transmitter-encoder circuit 22. The circuit performs signal coding and transmission to the signal beacon 1 at radio frequency. The circuit 22 is composed of an antenna 30, a small transmitter 31, and an encoder 32.
    [56] The antenna 30 is made by selecting a feature in consideration of its size as a single pole, radio control operation range, and design convenience.
    [57] The small transmitter 31 used is tuned to a 433.92 MHz transmission frequency and does not require a license in Europe as it conforms to current European regulations for this use frequency band. The transmitter generates an on-off key (OOK) modulated signal from the rasters received from the encoder 32 described above.
    [58] Encoder 32 generates 9-bit rasters that transmitter 11 uses for modulation. The first five bits correspond to the value assigned to the first five input pins of encoder 32 as bits of the address, while the remaining four bits are data bits. Of course, only two of the four bits are needed for the signals 18, 19. The elements shown in the figure are designed to achieve a 14 ms bit period to provide a baud rate of 72 bps.
    [59] The address formed by the first five bits of the rasters is specified by an assembly comprising microswitch 33 and drive registers 34 to select a high or low level for each of the encoder 32 address inputs. Allow. Therefore, a total of 32 different addresses can be identified with this binary encoding.
    [60] Description of the operation of the signal indicator (1) of the present invention is as follows.
    [61] When the signal beacon 1 is placed in the required place, the signal beacon is turned on if necessary. For this purpose, the photovoltaic cell 3 must generate energy and store it in the battery 7. In the electronic encoder-transmitter circuit 22, the encoder 32 generates a 9-bit raster (the first five bits are determined by the microswitch 33 and the drive register 43 as address bits and the remaining four Bits are data bits), the raster being transmitted wirelessly by means of the transmitter 31 at a transmission frequency of 433.92 MHz via the antenna. The raster is received by the receiver 26 and then interpreted by the decoder 27 the information encoded by the raster in the electronic transmitter-encoder circuit 22. To accomplish this, microswitch 28 and drive registers 29 provide five address bits, such as the five address bits of the raster generated by the transmitter-encoder circuit 22 described above.
    [62] Subsequently, the decoder generates signals 18 and 19, which are transmitted to the electronic control circuit 14 of the signal beacon 1. The signals 18, 19 are received by the block 16 together with a signal 20, which is obtained directly from the output voltage of the photovoltaic cell 3, indicating the presence or absence of light, which block the timer 15 and The light emitting diodes 13 are polarized to switch on / off the signal beacon 1 according to the received signal. In the case where the light emitting diode 13 emits light, the signal indicator lamp 1 is turned on for a light emitting period of 80 ms every second.
    [63] According to a preferred embodiment of the present invention, the signal beacon 1 also has a radar device inside the support 8 to obtain a vehicle for controlling the speed of the vehicle traveling along the road to control the vehicle speed. If the vehicle speed is greater than the allowable speed, the radar can automatically take a picture of the vehicle and present it to the driver as evidence.
    [64] Specific embodiments of the present invention are for reference only, and the signal sign of the present invention may be variously changed and modified for technically equivalent detailed structures without departing from the scope of the claims defined in the appended claims.
