Fundamentals
In general, if an error occurs while a home appliance is working, a user will request technical support from a call center, and then take steps to handle it on their own, or ask a technician to be sent to handle the issue.
However, such user response may not accurately inform the service center of the erroneous symptoms of the home appliance, so the service center cannot provide an appropriate response.
In order for a user to accurately explain the erroneous state of a home appliance to a call center, a scheme was recently considered that converts a symptom of a refrigerator into a predetermined pattern of a signaling sound, emits it, and transmits it to the center service through a telephone.
However, the signaling sound transferred in this way only contains information about the current state of the home appliance, but no information about the operation history performed so far.
In particular, among household appliances, refrigerators generally remain in operation once the power is turned on, and thus, the cause of current malfunction of a refrigerator is intimately involved with the state in which the refrigerator has been operated so far, as well as the current status of it.
Consequently, the conventional scheme, in which only current status information is emitted as a signaling sound, fails to accurately diagnose the status of a household appliance. ABSTRACT
One objective is to provide a household appliance, a household appliance diagnostic apparatus and a method thereof, which can convert and output product information to diagnose the status of a domestic appliance, and can capture the emission signal to thereby diagnose the status of the home appliance, so that it can be diagnosed in the event of a home appliance failure, and the failure can be responded to.
A home appliance, according to the description, includes a memory configured to store data generated in accordance with an operating state, a selection unit configured to receive a diagnostic execution command, a display unit configured to output an operating state , and a controller configured to generate product information based on the data stored in memory when the diagnostic execution command is entered via the selection unit, and to convert the product information into at least one code, and to issue the hair. minus one code by means of a signal via the display unit.
Furthermore, a diagnostic apparatus includes a camera configured to capture a signal displayed on a home appliance, such as an image signal, a first image processing unit configured to convert the image signal captured by the camera into image data for a plurality of frames of the image signal, a second image processing unit configured to analyze the image data of the first image processing unit for the plurality of frames, recognizing a code included in a frame, and extracting the data associated with the code, a processing unit configured to convert data extracted by the second image processing unit into product information, a diagnostic unit configured to diagnose the home appliance based on product information and generate a diagnostic result, and a controller configured to trigger the camera when a diagnosis mode is performed so that the image signal is captured. and to carry out the control so that the diagnosis result is generated.
In addition, a method of outputting a signal from a home appliance includes collecting diagnostic data to generate product information when an intelligent diagnosis command is entered, encoding the product information and converting the product information into at least a code in accordance with the previously stored code data, and outputting the coded product information by means of a display unit as a signal for a predetermined time.
In addition, a method of diagnosing a diagnostic apparatus includes capturing a signal emission from a display unit of a home appliance, such as a video, when a diagnosis mode is performed, detecting a code through data analysis. signal image, analyzing a frame of the image data to perform an error check and determine a valid frame, recognizing a code included in the valid frame to extract data, performing data conversion and extracting product information, and diagnosing the corresponding home appliance to the product information and outputting a diagnosis result.
Consequently, the household appliance, household appliance diagnostic apparatus, and method thereof can diagnose equipment failures, regardless of the surrounding environments, by converting stored product information to issue a predetermined form of a code, capturing the code. and diagnosing the home appliance, thus increasing convenience.
In addition, more accurate diagnosis of the operational state of the home appliance and quick response to a fault can be accomplished so that the efficiency of the service system is improved and user satisfaction is increased. BRIEF DESCRIPTION OF THE FIGURES

Advantages and aspects of home appliances, home appliance apparatus and methods of achieving the same are evident from the exemplary embodiments described in detail below in connection with the accompanying figures. However, the present invention is not limited to the described embodiments, and can be carried out in various ways. Exemplary embodiments are provided herein merely to fully describe the present invention.
The same reference denotations refer to the same components throughout the specification.
Fig. 1 is a view illustrating a diagnostic system including a home appliance and a diagnostic apparatus in accordance with an embodiment of the present invention.
Referring to Fig. 1, the diagnostic system, according to an embodiment of the present invention, includes at least one home appliance 100, 101, or 102, a diagnostic apparatus 200, and a diagnostic server 300.
The home appliance stores, as product information, data generated or detected during operation, converts the data and outputs the product information in the form of a predetermined code.
The diagnostic apparatus 200 captures and analyzes the product information issued by the domestic appliance in code form and extracts the product information from the captured data, thus diagnosing the domestic appliance.
At this time, the diagnostic apparatus 200 diagnoses the home appliance, and specifically, receives the diagnostic data from the diagnosis server 300 so as to diagnose the home appliance and transmit a diagnosis result to the diagnostic server 300.
Furthermore, the diagnostic apparatus 200 can send a request to diagnose the home appliance by transmitting product information to the diagnosis server 300. In such a case, the diagnostic apparatus 200 receives and outputs the diagnosis result from the diagnosis server 300 .
The diagnosis server 300 transmits data for diagnosis in response to a request from the diagnostic apparatus 200 and receives a diagnosis result. In some cases, the diagnosis server 300 may receive product information from the home appliance, in response to a request from the diagnostic apparatus, diagnose the home appliance, and transmit a diagnosis result to the diagnostic apparatus 200.
Below, by way of example, the home appliance is a refrigerator.
In the event that refrigerator 100 fails or refrigerator 100 does not operate normally due to an environmental factor of the place where refrigerator 100 is installed or user misoperation, a predetermined warning sound is emitted from refrigerator 100. User recognizes the sound and take appropriate action, and if necessary, contact a call center to inquire about the action. At this point, a call center operator provides a corresponding measure to the user.
Additionally, the user can also take some measures based on the manual of the diagnostic apparatus. If an intelligent diagnosis mode of the diagnostic apparatus is selected, a guide to handle any household appliance error is issued to the diagnostic apparatus.
The user can try to take measures to manipulate the refrigerator 100 according to the treatment method provided by the operator or the guide of the diagnostic apparatus, or can set a diagnosis mode in the refrigerator so that the status of the refrigerator can be diagnosed through the apparatus. diagnosis or call center.
The user sets the diagnosis mode in the refrigerator according to the guide and approaches the diagnostic apparatus 200 to a display unit 141 of the refrigerator, and then captures an emission from the display unit 141 of the refrigerator through a capture mode of the diagnostic apparatus .
In one example, if the diagnosis mode is set, the refrigerator encodes the stored product information and continuously issues a predetermined signal via the display unit 141. The user picks up the signal output from the display unit 141 of the refrigerator as a video through the diagnostic apparatus 200.
If the user brings the diagnostic apparatus 200 closer to the display unit 141 of the refrigerator, the diagnostic apparatus 200 recognizes the display unit 141 of the refrigerator and picks up the signal that is emitted from the display unit 141 and which continuously varies as a video and stores the video.
The cooler 100 may include a selection unit that allows the user to select to perform a diagnosis mode. The selection unit can include a button, a dial, a tactile switch, and a touch pad.
If entering a user-diagnostic mode by manipulating the select unit, the cooler 100 converts the product information into a predetermined signal and outputs the converted signal. The signal, as described above, is output through the display unit 141 and captured by the diagnostic apparatus 200, and the product information is extracted by the diagnostic apparatus analyzing the signal. The diagnostic apparatus can diagnose the refrigerator by extracting the product information from the video or if a date is needed for diagnosis, it can send a data request to a call center. Additionally, if the diagnosis is impossible in the diagnostic apparatus, the product information can be transmitted to a call center in order to carry out a diagnosis. The call center is connected to a communication network and can diagnose the refrigerator based on product information received from the diagnostic apparatus 200.
The diagnostic apparatus 200 can input a diagnostic result into the display unit, and/or transmit the diagnostic result to call center 300, and/or transmit the diagnostic result via email or via the user's cell phone. Additionally, if the refrigerator diagnosis is performed at the call center, the call center diagnoses the refrigerator according to the product information received from the diagnostic apparatus and transmits a diagnostic result to the diagnostic apparatus. In some cases, the diagnostic result can be transmitted to the user's email or cell phone. At this time, if the diagnostic result shows that repair is needed, the call center can send a technician to a technician and transmit the diagnostic result to the terminal technician's terminal.
Fig. 2 is a view illustrating an example where a signal is emitted from a home appliance and the signal is input into a diagnostic apparatus in accordance with an embodiment of the present invention.
Referring to Fig. 2, the display unit 141 of refrigerator 100 outputs information such as a set freezing temperature 141a, a set temperature of refrigeration 141c, and an operating mode of refrigerator 141b.
Once a diagnosis mode is set via the refrigerator selection unit 100, a refrigerator controller 160 converts and encodes the stored product information and outputs it via the display unit 141.
If the intelligent diagnosis mode is in progress, and the diagnostic apparatus 200 is approached from the display unit 141 as shown, and the diagnostic apparatus 200 picks up the display unit 141 of the refrigerator 100 through the camera 220 of the diagnostic apparatus 200.
The diagnostic apparatus 200 recognizes the signal output from the display unit 141 and captures the signal as a video, analyzes the captured image to extract the signal emission from the refrigerator, and extracts the product information from the signal, thus performing diagnostics on the refrigerator.
Fig. 3 is a block diagram illustrating a configuration of a home appliance in accordance with an embodiment of the present invention.
Chiller 100 completes a circulation cycle including compression, expansion, evaporation and condensation while a chiller circulates along chiller pipes. During such a circulation cycle, the cooler undergoes a phase change, whereby heat exchange is effected between the cooler and the surrounding air so that freezing or refrigeration takes place. For this purpose, the cooler 100 includes a compressor (not shown) to compress the cooler, an expansion valve (not shown) to expand the cooler, a heat exchanger (not shown) that functions as an evaporator to evaporate the cooler, and another heat exchanger (not shown) that serves as a condenser to condense the cooler.
A door of refrigerator 100 includes a control panel to control the operation of refrigerator 100 and allow the status of refrigerator 100 to be output by display unit 141 as a screen and/or sound.
The control panel includes the display unit 141 which displays and displays status information or fault information of the refrigerator 100 with a light emitting means such as an LED, LCD or organic EL, a sound emitting means such as as a horn or loudspeaker, which emits a sound, and an input unit 142 implemented as a mechanical button or capacitive/resistant touch button through which various operational commands can be entered by the user.
Referring to Fig. 3, refrigerator 100 includes a unit 142, a display unit 141, an insert/send controller 143, a memory 172, a detection unit 190, a modulator 182, a compressor 183, a fan of refrigerator compartment 184, a freezer compartment fan 186, a defrost heater 188, a condenser fan 189, a sound emitting unit 150, and a controller 160 that controls the general operation of the refrigerator.
The sensing unit 190 may include a refrigerator compartment temperature detector 191 which senses the temperature of the refrigerator compartment 120, a freezer compartment temperature detector 192 which senses the temperature of the freezer compartment 130, a defrost detector 193 which detects the surface temperature of the evaporator to determine whether it performs a defrost operation, a refrigerator compartment fan motor detector 194 which detects whether the refrigerator compartment fan compartment fan 184 operates normally, a refrigerator compartment fan motor detector 194 freezer compartment fan 195 which detects whether freezer compartment fan 186 operates normally, and a condenser fan motor detector 196 which detects whether a condenser fan 189, to radiate heat generated by the condenser when heat exchange. with the cooler is carried out, it operates normally.
Controller 160 analyzes the operational status of refrigerator 100 based on information collected through various detectors constituting detection unit 190, and insertion/emission controller 143 controls the status information detected by detection unit 190 to be displayed via the display unit 141.
The insert/send controller 143 alternates between the display unit 141 and the insert unit 142 provided on the control panel 140 and the controller 160. The insert/send controller 143 transfers various control commands entered by the user through the input unit. insertion 142 for controller 160, enables signals, characters and/or images, such as icons, to be displayed via display unit 141 in response to input control commands, or when information detected by detection unit 190 is transferred to the controller 160, it enables the status information to be displayed through the display unit 141 based on the transferred information.
Inserter unit 142 includes at least one input means that inputs a predetermined signal or data to refrigerator 100 through user manipulation and may include a manipulation unit 144 that receives various control commands for operating refrigerator 100 and a unit selection 145 which receives a command to perform a diagnosis mode to diagnose the refrigerator 100.
The selection unit 145 includes at least one input means, and when a diagnostic execution command mode is input, it applies the command to the controller 160 so that product information is encoded and output as a predetermined signal through the input unit. display 141.
At this point, the selection unit 145 can be constituted as a predetermined insertion means separate from the manipulation unit 144, but it is not limited thereto. For example, a specific insertion means constituting the manipulation unit 144 generally functions as the manipulation unit 144, but may be configured to perform a function as the selection unit 145 depending on a predetermined pressure pattern, such as for example , when held down for a predetermined time or longer, or repeatedly pressed within a predetermined time.
In the refrigerator 100 in accordance with an embodiment of the present invention, the inserter unit 142 includes a lock button that performs a key lock function that allows the user to lock the manipulation unit 144 and a compartment temperature adjustment knob. of the freezer to adjust the temperature of the refrigerator compartment 120.
At this time, if a diagnosis mode is set through the use of the lock button and the temperature adjustment knob, the refrigerator enters a lock mode, for example by pressing the lock button with the refrigerator door 122 remaining open , and then enters a diagnosis mode only when the freezer compartment temperature adjustment button is pressed before a predetermined time elapses. This can prevent the refrigerator from going into diagnostic mode unnecessarily due to an error in the manipulation of the manipulation unit 144, so that the diagnosis mode is only initialized when it appears evident that the user intends to diagnose the refrigerator 100.
Memory 172 stores product information. As described above, product information includes operational information detected and accumulated through detection unit 190 for a predetermined period of time while cooler 100 operates.
Here, the product information may include at least one of product identification, configuration information, operational information, and error detecting information.
Product identification is information to identify the type of target to be diagnosed using the diagnostic apparatus 200. The diagnostic apparatus 200 to be described below can be configured to perform diagnostics on various household appliances, such as a washing machine, an air conditioner , or a stove as well as a refrigerator, and the product identification may include information about the target for diagnosis performed by the diagnostic apparatus 200.
The setup information is user information input to set functions of the refrigerator 100. Examples of the setup information may include a freezer compartment set temperature, a refrigerator compartment target temperature, a refrigerator set temperature, the temperature Freezer compartment target, if you select quick freeze, high speed freeze, or express freeze setting to quickly lower the freezer compartment temperature in a short time, if a refrigerator being diagnosed includes a dispenser for removing water or ice , whether an air purifier mode is set to purify the air in the refrigerator compartment or freezer compartment, whether a test mode has been set to refrigerator test operation, and whether a display mode is set to display in a store.
Operational information is information for an operational state of refrigerator 100 and may include time information in a period of time during which product information has accumulated in memory 172, number of opening times of the door compartment that has been accumulated during a set time period, freezer compartment opening time that has been accumulated over a set period of time, an average temperature, maximum temperature and/or minimum temperature detected by the freezer compartment temperature detector for a set period of time, time refrigerator compartment activation time that has accumulated during a set period of time, number of refrigerator compartment door opening times that has accumulated during a set period of time, refrigerator compartment door opening time that has accumulated during an established period of time, an average temperature, te maximum temperature, and/or minimum temperature detected by the refrigerator compartment temperature detector for an established period of time, activation time of the refrigerator compartment fan that has been accumulated during an established period of time, an average temperature, maximum temperature and /or minimum temperature detected by an outdoor air temperature detector for an established period of time, the maximum temperature, an average temperature, maximum temperature, and/or minimum temperature detected by the defrost detector freezer compartment for an established period of time , an average temperature, maximum temperature and/or minimum temperature detected by the defrost detector refrigerator compartment for a set period of time, a freezer compartment defrost time and/or most recently performed defrost refrigerator compartment defrost time before a diagnosis is made, a defrost period of the most recently performed defrost freezer compartment before a diagnostic is performed, and an accumulated compressor start time over a set period of time.
Error detection information is information regarding whether various components making up the cooler operate normally. Error detection information may include information on whether water supply to an ice maker is performed normally, whether a water absorber or ice absorber provided in the dispenser 125 to withdraw water or ice when the user presses operates normally, various detection units, such as the freezer compartment temperature detector 192, the refrigerator compartment temperature detector 191, the outside air temperature detector 199, the freezer compartment defrost detector, and the freezer compartment defrost detector. refrigerator compartment operate normally, and if a drive device, such as a freezer compartment fan or a refrigerator compartment fan, operates normally.
When a signal is input from the selection unit 145 in accordance with entering the diagnosis mode, the controller 160 accesses the product information stored in the memory 172, generates a control signal in a predetermined format, and converts the signal from control in a predetermined code of the signal. Additionally, the controller 160 enables the converted control signal to be output through the display unit 141 in accordance with the manipulation of the selection unit 145.
Controller 160 includes a main controller 161 which controls the flow of emission or data entry to/from the refrigerator and generates a control command in accordance with data entry from detection unit 190 such that refrigerator 100 operates and a encoding unit 162 which converts product information into a control signal of the predetermined format according to an insert of the selection unit 145 and encodes the control signal.
When the selection unit 145 is inserted and entry into the diagnosis mode is made, the main controller 161 enables a start tone to be emitted through the tone emitting unit 150 to inform that the diagnosis mode is initialized and enables data predetermined to be displayed through the display unit 141 to inform that the diagnosis mode is performed. At this time, the insert/send controller 143 may take turns between the main controller 161 and the display unit 141 as described above.
Additionally, the main controller 161 enables a control signal generated in the encoding unit 162 to be encoded and output as a predetermined signal through the display unit 141 and controls the display unit 141 so that a predetermined display is outputted before and after of the signal is emitted or controls the sounding unit 150 so that an alert sound is emitted. However, the alert sound, in some cases, can be omitted. In this example, the main controller 161 enables an initialization code to be issued before the signal is issued and enables a termination code to be issued after the signal is issued.
Upon entering the diagnosis mode, the main controller 161 can stop the handling unit 144, except for the selection unit 145 and power button, from operating. As described above, how, in this mode, the entry into the diagnosis mode is initiated when a specific manipulation key, that is, the temperature adjustment button of the freezer compartment temperature remains pressed for a predetermined time, with manipulation keys blocked By the lock button, the operations of the power button and keys other than the temperature adjustment knob of the freezer compartment temperature whose functions were restricted, are limited before the lock button is released.
Encoding unit 162 accesses product information stored in memory 172 and encodes the product information according to a designated scheme, and adds a preamble and an error checking bit to the data signal to thereby generate a predetermined format of the data signal. control. Encoding unit 162 generates a control signal comprising a plurality of symbols by encoding product information.
Additionally, the encoding unit 162 splits the control signal to a predetermined size when generating the control signal, thus constituting a packet with a plurality of frames. Additionally, the encoding unit 162 can configure an IFS (Inter-Frame Space) between frames of the control signal.
Here, product information is data made up of the combination of 0's and 1's, and is a digital signal readable by controller 160. Controller 160 sorts product information data, allows specific data for refrigerator operation to be included, divides or sums to a predetermined size to thereby generate a control signal having a designated pattern, encodes the control signal, and applies the control signal to the display unit 141.
At this point, “encoding” generally denotes emitting a signal having a form that appears insignificant and is a process of performing encryption according to a predetermined rule. Encrypting is performing matching and converting a specific code format of a control signal in the cooler on a per-bit or per-byte basis. The diagnostic apparatus may include data associated with encryption and conversely output product information from the encrypted signal.
The sound emitting unit 150 can emit an alert sound or an effect sound corresponding to a status information of the refrigerator, upon entering the diagnosis mode, it emits an initialization sound to inform that the diagnosis mode has started to correspond with to a control command from the main controller 161, and when the emission of a sound including the product information is initialized and terminated, it emits predetermined alert sounds, respectively.
The display unit 141 displays, on the screen, the information entered by the selection unit 145 and the manipulation unit 144, operational information about the state of the refrigerator 100, and information according to the completion of the operation of the refrigerator in response to a command controller of the main controller 161. Additionally, the display unit 141 displays on the screen fault information regarding the refrigerator malfunction when the malfunction occurs.
Additionally, the display unit 141 displays a predetermined signal obtained by encoding the product information, which is output from the encoding unit, when the diagnosis mode is initialized in response to a control command from the main controller 161. At this time , the display unit 141 can use a plurality of 7 segments. According to the number of 7 segments used, the method of decoding the product information may also vary. In case an LCD is used, a predetermined form of a code can be issued.
Figs. 4(a) - 4(b) illustrate a structure of a control signal generated by decoding product information stored in a home appliance in accordance with an embodiment of the present invention.
As illustrated in Fig. 4a, the encoding unit 162 configures a packet with a plurality of frames. Encoding unit 162 adds a product identity and version information to the product information which is diagnostic data. This is done in an application layer. The overall packet size is, by way of example, 60 bytes, with 1 byte of version information, 7 bytes of product identification, and 52 bytes of product information.
At this point, version information is a version of the diagnosis algorithm and version information for the diagnosis algorithm or the entire diagnosis system and means of information in the name of the protocol corresponding to it.
For example, in case, as shown in Fig. 4b, the version is denoted as 0x01, the protocol name means ‘Intelligent Diagnosis for Chiller V1.0’. Product identification is an identifier to identify a product, and diagnostic data is product information to diagnose a refrigerator failure.
The version and product identification are directly entered by controller 160. On the other hand, diagnosis data, ie product information, is stored in memory 172. Consequently, if an intelligent diagnosis is performed, controller 160 loads the data stored in memory 172 and preliminary data the product information, ie diagnostic data.
Fig. 5 is a flowchart illustrating a method of outputting product information from a home appliance in accordance with an embodiment of the present invention.
Referring to Fig. 5, refrigerator controller 160 stores, during operation (S410), data measured by a plurality of detectors, data analysis result, or operational setting data in memory 172 (S420).
If a command to enter diagnosis mode is inputted by input to selection unit 145 of input unit 142 (S430), controller 160 performs a diagnosis mode. At this time, while the diagnosis mode is in progress, the main controller 161 disregards an input from the controller 160 and issues an alert in at least one form among letter, an image and an emoticon for support entry into the diagnosis mode through the unit. display 141. In some cases, a predetermined alert sound may sound.
Encoding unit 162 accesses data stored in memory 172 and collects diagnostic data to thereby generate product information (S440).
Additionally, the encoding unit 162 encodes the product information into a control signal comprising a plurality of frames in accordance with a designated format (S450) and encodes the control signal in accordance with established data on a per bit or per byte basis. . For example, for the control signal to be '0011', decoding is performed such that a code in the form of 'C' is emitted or for the control signal to be '1010', decoding is carried out such that a code with a shape 'I' is issued.
The main controller 161 issues an initialization code before outputting a signal converted from the product information via the display unit 141 so as to inform that the signal is to be output (S460).
A predetermined time after the initialization code is issued, the main controller 161 outputs via the display unit 141 a predetermined signal obtained by decoding the product information and converted by the encoding unit 162 (S470). At this time, the emission signal can be continuously changed and emitted for a predetermined time.
If the signal output is complete, the main controller 161 issues a termination code (S480).
At this time, the initialization code and the termination code can consist of a specific message, a picture or a special letter, and a code is used which is assigned in advance through data exchange with the diagnostic apparatus.
If the domestic appliance, that is, the refrigerator, completes the signal emission, the main controller 161 releases the diagnosis mode and operates normally.
Additionally, as described above in connection with Fig. 2, the diagnostic apparatus picks up a signal emission from the display unit of the home appliance for a predetermined time and performs signal image analysis to extract product information, thereby diagnosing the appliance domestic.
Fig. 6 is a view illustrating the configuration of a display unit that outputs product information in a home appliance in accordance with an embodiment of the present invention.
Referring to Fig. 6, the display unit 141, which outputs coded product information as a predetermined signal, uses 7 segments, for example.
Display unit 141 may include a plurality of 7 segments each of which has 7 light emitting units configured to represent a predetermined shape of a single character or numeral. In response to a control signal from the controller 160, each of the light-emitting units, that is, first for fourteen light-emitting units (0 to 6, A to G) lights on or off, so that a specific code for the display unit 141.
As described above in connection with Fig. 2, a cooling temperature and a freezing temperature and one can each be displayed, and thus any or all can be used to output a signal.
Below, an example is described where a two-digit code is issued.
Figs. 7(a) - 7(d) are views illustrating an example of outputting product information on the display unit of Fig. 6.
Referring to Figs. 7(a) - 7(d), the controller 160 issues a coded signal to the display unit 141 as a two-digit code and enables them to be issued for a predetermined time and enables them to be continuously changed.
The main controller 161 sequentially outputs signals converted by the encoding unit 162 to the display unit 141 according to an order at a predetermined time interval.
Thus, an encoded signal is output during a predetermined time, while changing at a predetermined time interval as shown in Figs. 7a,b,c, and d. As shown in Fig. 7a, the first, third, fourth, fifth, sixth and seventh light emitting units 0, 2, 3, 4, 5, and 6 and the eighth, ninth, eleventh, eleventh, twelfth , thirteenth light emitting units A, B, D, E, F, and G are lit so that the first code is emission, and in a predetermined time. As shown in Fig. 7b, the fifth light emitting unit 4 and the tenth light emitting unit C and D are lit so that the second code is emitted.
At a predetermined time, as shown in Fig. 7c, a code is issued, and then, as shown in Fig. 7d, a code is issued. For example, the display unit 141 may emit with codes changing 15 times per second.
Fig. 8 is a block diagram illustrating the configuration of a diagnostic apparatus in accordance with an embodiment of the present invention. Referring to Fig. 8, diagnostic apparatus 200 includes a display unit 240, an input unit 245, a communication unit 290, a data unit 280, a camera 220, the first image processing unit 250, the second image processing unit 260, data processing unit 270, diagnostic unit 230, and controller 210 which controls the general operation of the diagnostic apparatus.
The display unit 240 displays various information including a diagnosis progress status or diagnostic result for the diagnostic apparatus. Display unit 240 also outputs an image preview screen captured through camera 220.
Data unit 280 stores diagnostic logic and diagnostic data items for diagnosing the home appliance. A data structure stored in data unit 280 may include a table that stores at least one diagnostic logic (hereinafter 'diagnostic logic table') and a table that stores at least one diagnostic data item (hereinafter , 'diagnostic data table). Diagnosis logic table and diagnosis data table can be managed separately depending on a target for diagnosis.
For example, diagnostic apparatus 200 is not necessarily configured to diagnose just the refrigerator and can be configured to diagnose household appliances in addition to the refrigerator. In such a case, the diagnosis logic table can separately store a washing machine diagnosis logic to diagnose a washing machine and a refrigerator diagnosis logic to diagnose a refrigerator. Likewise, the diagnosis data table can separately store data items needed to diagnose a washing machine and data items needed to diagnose a refrigerator.
Additionally, if a signal output to the display unit of the home appliance is captured as an image, the data unit 280 stores image processing data to analyze frames for the image and extract a code from the image and code data to extract the product information from the code, and diagnostic data result.
Data unit 280 may include a recording medium, such as flash RAM, ROM, or NAND, as a storage device for recording captured image data.
Camera 220 captures a surrounding image with lenses and an image detector in a capture mode. An image frame captured by the camera 220 can be displayed in the display unit 240. The image frame captured by the camera 220 can be stored in the data unit 280 as image data by the first image processing unit 250 or it can be transmitted to the outside through the communication unit 290.
As described above in connection with Fig. 2, the camera 220 can capture the display unit 141 of the home appliance, e.g., a refrigerator, as a video. At this time, as illustrated in Figs. 7(a) - 7(d), since the codes are changed at a predetermined time interval in the refrigerator display unit 141, a video is captured in which the codes are continuously changing and a predetermined code is captured in each frame of image.
First image processing unit 250 processes an image frame, such as a still image or video, received from camera 220. First image processing unit 250 generates a still image or video from an insert image frame and stores in data unit 280.
The second image processing unit 260 analyzes the image frame from the video generated by the first image processing unit 250 and recognizes a code from the image frame, thereby extracting the code. The second image processing unit 260 recognizes the home appliance display unit from the image frame, extracts the signal emitted from the display unit, i.e. the code, on a per frame basis, chooses a valid frame, and extracts the code.
The captured video includes a plurality of image frames, each of which includes a code. As various frame shapes are provided, such as a frame where the code shape has been clearly captured, a frame where a code is about to be changed, or a frame where the same code as the previous frame has been captured, the second image processing unit 260 selects a valid frame by recognizing the code captured in each image frame.
The second image processing unit 260 analyzes a plurality of codes extracted from a second image processing unit 260 and performs inverse transformation based on the code data stored in the data unit 280 to thereby extract product information from the home appliance from of the plurality of codes. At this time, the second image processing unit 260 extracts a control signal from the plurality of codes and decodes the control signal according to a designated conversion scheme, thus extracting the product information.
The diagnostic unit 230 analyzes the product information extracted by a second image processing unit 260 according to a diagnostic logic and diagnostic data to thus diagnose the state of the domestic appliance. The diagnostic unit 230 generates diagnostic results including whether there is a fault, cause of the fault, and a measure to be taken and a measure to be taken for the fault, and sends the diagnostic results to the controller 210.
As a large amount of product information is included in the signal emitted from the home appliance, the diagnostic unit 230 analyzes each data item included in the product information and diagnoses the home appliance depending on the correlation between the data items.
At this time, as the product information can include product identification information, the diagnostic unit 230 can identify the target type for diagnosis through the product information extracted through the data processing unit 270, and consequently can access items of data used to diagnose the refrigerator and a refrigerator diagnostic logic according to the diagnostic target of the data unit 280, thus performing a diagnosis.
Controller 210 can output a diagnostic result to display unit 240, and depending on the settings, can transmit the diagnostic result to a call center 300 via communication unit 290 or can transmit the diagnostic result to a destination registered in the information of the user, for example, the user's email account or the user's terminal.
Additionally, if additional data is needed in the diagnosis of the home appliance by the diagnostic unit 230, the controller 210 may send a data request to a call center 300 via the communication unit 290. In some cases, when determining that it is impossible to the diagnostic unit 230 performs a diagnosis, the controller 210 can transmit information extracted from the product to a call center through the communication unit 290 in order to send a diagnosis request to the call center. At this time, if a diagnostic result is received from the call center's diagnosis server server, the diagnostic result is output to display unit 240, and/or is transmitted to the user's e-mail account or user's terminal.
If the extracted product information includes an error, that is, if the product extraction information is abnormal, in response to a request from the data processing unit 270, the controller 210 may enable an alert requesting re-issuance of a signal to be emitted via display 240 in at least one form of a letter, an image, an emoticon, and a special sign.
Fig. 9 is a flowchart illustrating a method of inputting product information by a diagnostic apparatus in accordance with an embodiment of the present invention.
Referring to Fig. 9, the controller 210 of the diagnostic apparatus triggers the camera 220 when it receives a command to execute the diagnosis for the domestic appliance in accordance with manipulation of the insertion unit 245.
At this time, the user approaches the diagnostic apparatus to the display unit of the home appliance so that the display unit of the home appliance is captured as described above in connection with Fig. 2.
If camera 220 is triggered, display unit 240 outputs an image insert via camera 220 as a viewing screen (S510).
The input of image data through camera 220 is processed by the first image processing unit 250 (S520), and the second image processing unit 260 analyzes the image data processed by the first image processing unit 250 on a basis per frame to look for an initialization code (S530).
At this time, the first image processing unit 250 processes an image captured through the camera 220, i.e. an image signal input from the camera image detector, through a predetermined code. The second image processing unit 260 analyzes the image data processed by the first image processing unit 250 on a per-frame basis and looks for a specific code. At this time, the image data processed by the first image processing unit 250 is temporarily stored.
If among the image frames inserted in the previous state, one includes an initialization code (S540), the second image processing unit 260 applies the initialization signal to the controller 210, and the controller 210 controls the camera 220 in accordance with the initialization signal entered to initialize video capture (S550).
At this time, the first image processing unit 250 discards the image data in the previous state before temporarily storing it, and if the initialization signal is inserted so that the video capture is started, it processes the insertion of data from image from camera 220 and stores the processed image data in data unit 280.
If video capture starts, the second image processing unit 260 analyzes each frame of the image data entered from the first image processing unit 250 and recognizes a predetermined signal emission through the display unit of the home appliance, or that is, coded product information.
The second image processing unit 260 sorts frames having captured codes to establish a valid frame, and discards the other frames.
Additionally, as video capture begins, the second image processing unit 260 searches for a termination code between known codes by performing per-frame analysis on the image data processed by the first image processing unit 250 (S560).
If there is a frame including the terminate code, the second image processing unit 260 applies a terminate signal to controller 210, and controller 210 then applies a terminate capture command to camera 220 to thereby stop capturing ( S580).
If the capture is completed, the first image processing unit 250 finally stores the image data (S590).
Here, the initialization code and the termination code are codes respectively indicating the initialization and termination of outputting product information when the product information is encoded and outputted as a predetermined signal in a home appliance, and are preset codes. The second image processing unit 260 analyzes the frames and recognizes the codes, and detects a preset start code or stop code among the recognized codes and sends an start signal or stop signal to the controller 210.
The diagnostic apparatus may not only recognize the initialization code and the completion code of the insert image to thereby capture encrypted product information as described above, but in some cases, it may also recognize only one of the initialization code and the code. to initialize or end the video capture. Additionally, the diagnostic apparatus may initiate or terminate video capture in response to a key input from the input unit 245.
Fig. 10 is a flowchart illustrating a method of processing product information of a diagnostic apparatus in accordance with an embodiment of the present invention.
Referring to Fig. 10, if product information is encoded and output as a predetermined signal in a home appliance, the diagnostic apparatus as described above picks up a signal output from the display unit of the home appliance as a video.
The first image processing unit 250 performs image processing on outputting the image signal on outputting the image signal from the camera 220 on a per frame basis, and the second image processing unit 260 recognizes a code included in each frame for select a valid frame (S620).
At this time, case, according to a frame rate being captured and a speed at which the home appliance signal is changed, the same code is captured and included in a plurality of frames or by detecting each code of a capturing frame the moment a code is changed, the second image processing unit 260 deletes frames including codes impossible to recognize and duplicates frames capturing the same code and chooses frames including possible codes to recognize as valid frames.
The second image processing unit 260 recognizes a code of a valid frame and calculates a signal value corresponding to the code based on the code data stored in the data unit 280, thereby detecting the data (S630).
If code recognition is completed on the plurality of image data frames, the data processing unit 270 combines and decodes the data extracted by the second image processing unit 260 (S650) to thereby extract the product information (S660) .
The diagnosis unit 230 diagnoses the home appliance on the basis of the product information extracted by the data processing unit 270 and generates a diagnostic result.
Controller 210 outputs the diagnostic result to display unit 240 and/or transmits the diagnostic result via communication unit 290 to a call center and/or user terminal.
Fig. 11 is a flowchart illustrating a method of processing an image frame of a diagnostic apparatus in accordance with an embodiment of the present invention. As described above, a method of recognizing image data frame codes and choosing a valid frame is as follows.
Referring to Fig. 11, the second image processing unit 260 checks a serial number of an image data frame (S710). If the frame serial number is a normal serial number, according to a predetermined order, an error check is performed on the frame (S720).
In response to a result of the frame error check, the second image processing unit 260 determines whether the frame is normal (S730), and if the frame is normal, adjusts the frame as a valid frame (S810).
On the other hand, if the result of the frame error checking shows that the frame is abnormal, that is, if an error occurs, it is identified if an additional serial number is present (S740), and in case of no serial number addition is present, the frame is set as a valid frame (S810).
At this time, if no additional serial numbers are present and an error occurs, the frame is determined to be a bad frame (S820).
If the frame serial number is abnormal, it is determined whether the frame serial number is a previous serial number (S760).
If the frame serial number is an earlier serial number, it is determined whether the frame is a blank frame (S770), and if the frame serial number is an earlier serial number and the frame is a blank frame , the frame is processed as a valid frame (S810). If the frame serial number is a previous serial number and the frame is not a blank frame, validation is checked (S780).
It is determined whether the frame is valid, and if the frame is valid, the frame is set as a valid frame (S810), or otherwise as a bad frame (S820).
If the frame serial number is abnormal and not a previous serial number, it is determined whether the frame is a bad frame (S790). If the frame is a bad frame, the frame is adjusted with a bad frame and, unless the frame is a bad frame, if the frame is a white frame it is checked (S770), and according to a check result , the frame is set as a valid frame (S810) or the frame validation is checked (S780).
As described previously, the frame is set as a valid frame or a bad frame through validation checking.
After frame validation is determined, the bad frame is discarded (S830), and a code included in a valid frame is recognized and the product information is extracted, and based on the product information, the diagnostic apparatus is diagnosed.
