In other words, it is impossible for conventional electronic devices to detect more subunits than the number of CPU terminals.

  In addition, in the electronic device capable of displaying an error by itself, unlike the techniques of Patent Documents 1 and 2, since the user can visually recognize the error display, it is also possible to request repair of the electronic device manufacturer or the like. However, since it is impossible for the user to distinguish between an error that requires repair and an error that does not, repair requests and inquiries to the support desk increase.

The essential obstacles are extracted from the data, and their analysis becomes easy. As a result, the reliability of the electronic device can be improved.

  An electronic device according to the present invention is a device including a plurality of subunits and a main unit that controls each subunit. For example, various devices including AV devices such as a television set, an AV recorder, and an AV player are included. Is mentioned. Hereinafter, the present invention will be described by taking a television device as an example. However, the present invention can be similarly applied to other electronic devices, and can be similarly applied to a television device other than the illustrated configuration.

  FIG. 1 is a diagram illustrating a configuration example of a television apparatus according to an embodiment of the present invention, where 1 is the television apparatus. The television apparatus 1 illustrated in FIG. 1 includes a main unit 12 that controls the whole, and further includes a digital broadcasting unit 11, an interface (IF) unit 13, a panel control unit 14, an inverter unit 15, a display 16, and a backlight 17. Is provided. Here, the IF unit 13 includes a communication unit 13c for communicating with a service center and the like, and a light receiving unit 13d for receiving an operation signal emitted from a remote controller.

  The display 16 is a liquid crystal panel or the like and is controlled by the panel control unit 14. The backlight 17 is a fluorescent tube or the like and is controlled by the inverter unit 15. The display 16 and the panel control unit 14 constitute a display unit, and the backlight 17 and the inverter unit 15 constitute a backlight unit. Thus, the television apparatus 1 includes the digital broadcast unit 11, the IF unit 13, the display unit, and the backlight unit as subunits controlled by the main unit 12.

  Each subunit includes an abnormality detection means (not shown) for detecting an abnormality, and a wireless transmission means for wirelessly transmitting information on the detection result of the abnormality detection means to the main unit 12. Here, as described with the display unit and the backlight unit as sub-units respectively, an abnormality such as an overtemperature of the display 16 continuing for a predetermined period can be detected on the panel control unit 14 side. Abnormalities such as lamp burnout can be detected on the inverter unit 15 side. That is, the abnormality detection unit and the wireless transmission unit will be described as being provided in each of the units 11 and 13 to 15.

  The abnormality detecting means may be installed at a necessary place on the circuit of each unit 11, 13-15. The abnormality detection means usually has different detection targets and detection methods depending on the units 11 and 13 to 15 on which the abnormality detection means is mounted. As an abnormality, an abnormality detected by various sensors such as a temperature sensor, an abnormality detected by the presence / absence of a current, a current value, a voltage value, etc., an abnormality detected by exceeding a use time (for example, a use time of a fluorescent tube), Alternatively, there may be a program (firmware) operation stop abnormality, exception processing abnormality, or the like.

  The wireless transmission means is connected to each of the installed abnormality detection means. Note that one wireless transmission unit may be connected to the plurality of abnormality detection units, but at least one wireless transmission unit is installed in one unit.

  In FIG. 1, such a wireless transmission means is exemplified by an IC tag. An IC tag is a tag that performs short-range wireless communication using an electromagnetic field or radio wave, such as an RF tag using RFID (Radio Frequency IDentification) technology, and normally an IC chip and an antenna that store a unique ID in a memory It consists of and.

  In the example of FIG. 1, the digital broadcast unit 11 has first to third IC tags 11a to 11c, the IF unit 13 has seventh and eighth IC tags 13a and 13b, and the panel control unit 14 has ninth and tenth ICs. The tags 14a and 14b are provided, and the inverter unit 15 is provided with eleventh and twelfth IC tags 15a and 15b, respectively. Here, only an example in which a plurality of IC tags are provided for each one subunit is shown, but only one IC tag may be provided for one unit.

  The main unit 12 includes a CPU 12a and wireless reception means (illustrated by the receiving unit 12b) that wirelessly receives information transmitted by the wireless transmission means. Here, the “CPU” includes a unit called MPU (Micro Processing Unit) as a concept.

  Similarly to the subunit, the main unit 12 also includes an abnormality detection unit that detects an abnormality, and a wireless transmission unit that wirelessly transmits information on the detection result of the abnormality detection unit to the receiving unit 12b of the main unit 12. Are preferably provided. Information transmitted by the wireless transmission means on the main unit 12 side is also received by the receiving unit 12b. The details of the abnormality detection means and the wireless transmission means are as described for the units 11 and 13 to 15. As an example of the wireless transmission means of the main unit 12, FIG. 1 shows an example in which three IC tags 12c to 12d are provided.

  In addition, at least one of the plurality of subunits mounted on the television device 1 is a subunit with a notification function having notification means. The notifying means is means for notifying guidance, which will be described later. In the example of FIG. 1, the display unit including the panel control unit 14 and the display 16 will be described as corresponding to the subunit with the notification function. Note that a speaker unit capable of notifying the guidance by voice output can be applied as a subunit with a notification function so that the CPU 12a transmits a notification instruction to the speaker unit. Thereby, the user can know the content of notification by voice. Further, the communication unit 13c in the IF unit 13 may be applied as a sub-unit with a notification function so that the CPU 12a transmits a notification instruction to the communication unit 13c. In this case, the notification instruction corresponds to an instruction to transmit a sentence of notification contents to a user's e-mail address registered in advance, so that the user can obtain the notification contents with his / her mobile phone or PC. In addition, when a serious abnormality that may cause a fire is detected, a notification is made via the network to an address registered in advance as the manufacturer or distributor of the television apparatus 1 to enhance safety. Can do.

  FIG. 2 is a diagram for explaining the difference between the main unit in the television apparatus of FIG. 1 and the main unit in the conventional television apparatus. Here, FIG. 2A is a diagram illustrating a configuration of the main unit in the television apparatus of FIG. 1, and FIG. 2B is a diagram illustrating a configuration of the main unit in the conventional television apparatus.

  In the present invention, as shown in FIG. 2A, the CPU 12a described above has one input terminal for inputting information received by the receiving unit 12b. The CPU 12a determines a failure occurring in the television device 1 based on information (information regarding abnormality) input to the input terminal. Here, the failure includes a “temporary failure” that can be recovered by a simple operation such as restarting the television apparatus 1 and a “failure” that requires repair.

  As described above, in the television apparatus 1, even if the CPU 12a of the main unit 12 is not provided with an abnormality detection result input terminal for the total number of abnormality detection means provided in all the subunits, ) Information can be obtained from one wireless receiving means, and failure determination can be performed. In other words, in the television apparatus 1, it is possible to detect abnormality in subunits equal to or more than the number of terminals for inputting abnormality detection results of the CPU 12a.

  On the other hand, in the conventional system, the CPU performs error detection by monitoring the input state of each terminal, and depending on the type of error, it is necessary to use a dedicated terminal. For example, conventional temperature error detection is in the input state of the AD terminal, conventional synchronization error detection is in the input state of the INT (interrupt) terminal or timer terminal (T terminal), and conventional power supply error detection is in the input state of the INT terminal. , Each can be detected. When three terminals are provided as shown in FIG. 2B, the CPU 30 can input the occurrence of the temperature error, the occurrence of the synchronization error, and the occurrence of the power supply error from three locations (that is, each of them). It is possible to detect the occurrence of errors at three locations). And in CPU30, when those terminals are used for another use, it is necessary to add a terminal only for detection. As described above, the conventional CPU 30 has a limit on the number of errors that can be detected due to restrictions on the number of terminals. Therefore, when adding a subunit to an electronic device due to a design change or system upgrade accompanying a model change or minor change, the same CPU 30 is left as it is. It may be necessary to replace the CPU with a terminal that cannot be used and has many terminals.

  In the present invention, the CPU 12a instructs the subunit with a notification function to notify the guidance for eliminating the determined failure. In the case of the example of FIG. 1, the CPU 12 a sends an instruction to the panel control unit 14.

  The guidance is presented to the user by display and / or voice output in order to eliminate the failure, that is, to eliminate and restore the failure that causes the abnormality detected in each unit. The failure and the method for eliminating the failure differ depending on the location of the abnormality and the combination of the locations of the abnormality. Therefore, the CPU 12a stores a failure information list in the internal memory 12f (or connected memory), refers to the failure information list, and according to information (information regarding abnormality) input to the input terminal, A different guidance is selected and a notification instruction is given to the panel control unit 14. Since the information related to the abnormality is input to the CPU 12a according to the unit in which the abnormality is detected (in this example, one or more of the abnormality detection means installed in the units 11 to 15 is detected), the guidance is abnormal. The guidance corresponding to the detection location is selected. In this way, the television apparatus 1 can notify the user of guidance for eliminating the failure. The failure information list will be described later with an example.

  In the case of a failure that cannot be reported by the sub unit with the notification function (in this example, the display unit), or a failure that cannot be displayed on the display 16 in this example, the CPU 12a, for example, communicates with the IF unit 13. A notification instruction may be sent to the unit 13c or a second subunit with a notification function such as a video output terminal (not shown). Thereby, even if the notification on the display 16 cannot be made, the user can know the guidance by the output from the video output terminal or the e-mail to the PC / mobile phone.

  The above-described failure information list and guidance selection will be exemplified with reference to FIG. FIG. 3 is a diagram showing an example of a reference table (failure information list) for executing a guidance display instruction by the CPU in the television apparatus of FIG. 1, in which 20 is a failure information list.

  Here, it is assumed that the IC tag mounted on each unit is an active type. That is, an example is given in which each IC tag transmits information by itself when the occurrence of an abnormality (detection of abnormality by the corresponding abnormality detection means) is a trigger (information output condition), and the receiving unit 12b is an IC tag reader. Further, each IC tag transmits a unique ID as information.

  Of each IC tag, the IC tag that has received an abnormality detection by the abnormality detecting means voluntarily transmits a unique ID at the time of detection. The receiving unit 12b, which is an IC tag reader, receives this ID and transmits it to the CPU 12a. That is, the receiving unit 12b in this example becomes an ID receiving circuit connected to the CPU 12a, and only transmits the ID received from the IC tag to the CPU 12a. On the other hand, the CPU 12a receives this ID, but receiving the ID means receiving abnormal information from the IC tag. The CPU 12a refers to the failure information list 20 in the memory 12f, and searches for the corresponding guidance using the received one or more IDs as a search key. The CPU 12a selects the retrieved guidance and instructs the panel control unit 14 to display on the display 16. The guidance preferably includes time information when the ID is received.

  For example, when the received ID is only ID = 1, the CPU 12a refers to the failure information list 20, selects a guidance such as “A error, please do”, and displays the selected guidance. The display unit (actually the panel control unit 14) is instructed. The panel control unit 14 displays the guidance on the display 16, and the user visually recognizes the guidance, and according to the guidance, the work for eliminating the obstacle (for example, the operation of restarting the television apparatus 1, the manufacturer of the television apparatus 1, etc.) Request for repair). As illustrated in FIG. 3, the failure information list 20 is a list that returns different guidance depending on whether ID = 1, ID = 2, and ID = 1,2. Accordingly, guidance according to the received ID can be returned.

  In this way, if the abnormality is notified by the ID, the abnormality detection process can be unified and the process can be simplified. Further, in the case of ID, the failure information list for the ID is stored in the memory 12f, and it is only necessary to perform processing corresponding to the failure information list by the notified ID. All you need to do is add the ID you want to increase and the corresponding guidance.

  In addition, the CPU 12a uses the internal memory 12f (or connected memory) as a failure history list together with the occurrence date and time of failure at the time of failure determination so that the CPU 12a can refer to the failure analysis that may be performed at a later date. It is preferable to memorize. The failure state includes not only information (ID received by abnormality detection) corresponding to the search key for selecting the guidance of the failure information list 20 but also the user setting of the television device 1 at that time. Is preferred. By reading out such a failure history list, it is possible to check the status of the television apparatus 1 at the time of the failure and the usage status of the user when the failure is reached, so the main unit and many subunits are provided. Even in the configuration, the fault location can be easily identified. Therefore, it is possible to prevent repeated repairs due to failure to identify the faulty part or replacement in units, thereby improving the efficiency of repairs and reducing the cost of service.

  Next, processing when the determined failure is a temporary failure that can be resolved by the user (including guidance notification), and processing when the determined failure is a failure that cannot be resolved without requesting repair ( (Including guidance notification).

  In the case of a temporary failure, a failure information list 20 is created so that information indicating an operation for solving the failure is notified as a guidance, and a case where a temporary failure actually occurs is handled. It is good to notify the guidance to do. For example, guidance such as “Please restart (power OFF / ON).” Or “Please unplug the power outlet and plug it in again.” May be notified. Taking the abnormality detection in the digital broadcast unit 11 as an example, the failure that can be handled by the user includes a case where a temperature sensor installed around the tuner detects a predetermined temperature or more. In such a case, a message prompting confirmation of whether the vent is not blocked may be displayed as guidance. Further, the panel control unit 14 may display the same guidance when a temperature equal to or higher than the threshold value has passed for a predetermined time by the temperature sensor.

  On the other hand, the case of a failure refers to a case where a fatal error has occurred and cannot be restored by user support and only a repair is requested. For example, taking the digital broadcast unit 11 as an example, this is the case where the CPU 12a receives an ID detected by an abnormality detection means installed in the power supply unit of the tuner and transmitted from the corresponding IC tag.

  In such a case, the CPU 12a provides information on the contact information of the manufacturer (such as a support center of the manufacturer) or the seller of the television apparatus 1 as guidance to the sub unit with the notification function (in this example, to the panel control unit 14). Instruct to inform. Examples of the contact information include a telephone number, an address, and an e-mail address. In addition, it is preferable to simultaneously notify an error number or the like transmitted when contacting the manufacturer or the seller. Such contact information may also be displayed in the case of a temporary failure.

  As in the example of FIG. 1, when one of the plurality of subunits mounted on the television apparatus 1 is a communication unit, the CPU 12a not only provides a notification instruction but also sends a communication center 13c to the support center. It is preferable to instruct to make a report. In the example of FIG. 1, the IF unit 13 is regarded as a subunit, but the communication unit 13c is also provided with an IC tag 13b and can be regarded as a subunit.

  More specifically, in the case of a failure, that is, when there is only a repair method for eliminating the determined failure, the CPU 12a informs the communication unit 13c of information about the failure and the user of the television apparatus 1 An instruction is given to notify the destination-identifiable information to an address registered in advance as the support center of the television apparatus 1 via the network. In addition, when notifying the support center, the guidance may include that the notification has been made.

  Here, the support center is set by the manufacturer or distributor of the television apparatus 1, and the address may be an IP address or an e-mail address. Further, the information that can specify the contact information of the user refers to device specifying information, a user contact information registered in advance in the television device 1, or the like. In the case of device identification information, if the manufacturer or distributor has information that associates the manufacturer or distributor with the contact information of the user (address or telephone number or e-mail address, etc.), the user contact information can be specified. .

  In addition, although the example in which the notification to the support center via the communication unit 13c is executed only for the “failure” that cannot be dealt with by the user has been shown, Good.

  In addition, the temporary failure and the failure are described separately, but depending on the type of abnormality, it may not be possible to determine whether the failure is a temporary failure or a failure at a time. In such a case, it may be determined that a failure has occurred when the same ID is received after the user has made an operation according to the guidance. Whether or not the same failure (that is, the received IDs are the same) can be determined by the CPU 12a referring to the failure history list in the memory 12f, and the guidance is also different for the first time and for the second and subsequent times. The information list 20 may be prepared.

  For example, in the first guidance, “XX error. Please turn the power on again.” Is displayed. From the second time on, “XX error. Repair is required. The service center has been notified. "Please wait for a while until you get in touch." In another example, the first guidance displays “△△ is abnormal. Please unplug the outlet.” Etc., and after the second, “△△ is abnormal. Repair is required. Notify the service center. "Please wait for a while until you get in touch." From the second time onward, at the same time as this guidance, the service center is notified such as "A failure has occurred at the user's home. ◇ ◇ Abnormal. Please contact phone number xxx-xxx-xxx." That's fine.

  With reference to FIG. 4, the flow of processing in the television device 1 as described above will be described with an example. FIG. 4 is a flowchart for explaining a processing example of guidance display and notification in the television apparatus of FIG.

  First, an abnormality detection signal is input from the abnormality detection means to the IC tag (step S1). Next, the IC tag related to the abnormality detection transmits the ID, and the receiving unit 12b receives the ID (step S2). Subsequently, the receiving unit 12b transmits the ID to the CPU 12a, and the CPU 12a receives the ID (step S3), and adds the ID to the failure history list in the memory 12f together with the reception time (step S4). Then, the CPU 12a reads the failure information list 20 from the memory 12f (step S5), and searches for guidance corresponding to the received ID (step S6). Subsequently, the CPU 12a determines whether the read guidance can be displayed on the display unit, that is, whether the failure corresponding to the received ID is a failure indicating that the display unit cannot be displayed. (Step S7).

  If YES in step S7 (display is possible), the CPU 12a sends an instruction to display guidance on the screen to the panel control unit 14, and the display 16 displays the guidance and notifies the user (step S8). On the other hand, if NO (cannot be displayed) in step S7, the CPU 12a instructs other means (in this case, the communication unit 13c) to notify the guidance, and the communication unit 13c transmits the notification contents by e-mail or the like. (Step S9). After step S8 / S9, the CPU 12a determines whether or not the fault needs to be notified to the service center based on the received ID (step S10). In the case of NO in step S10, the processing is terminated. Only in the case of YES (if necessary), the communication unit 13c is instructed to notify the failure information, the occurrence time (the reception time described above), and the user contact information. And the communication unit 13c performs notification according to the instruction (step S11).

  The active IC tag that generates only the unique ID has been described above. However, in the above example, the CPU 12a can obtain only an abnormal place. Depending on the location of the anomaly detection means, there are some that can identify the type of anomaly only at the location of the anomaly, but there are cases where this is not the case.

  Therefore, two or more IC tags may be provided for one abnormality detection unit, and the abnormality detection unit may be configured to vary the IC tag that transmits the detection result according to the type of abnormality. By adopting such a configuration, even if the IC tag transmits only the ID at the time of abnormality, the CPU 12a receives the ID via the receiving unit 12b and is detected from the previously stored failure information list 20. The type of abnormalities can be determined. In addition, regarding how to classify the type of abnormality, when the abnormality detection means has an abnormality (temporary failure) that can be handled by the user, the detection result is output to one IC tag and the user cannot respond. When such an abnormality (failure) occurs, the detection result may be output to the other IC tag.

  The case where the wireless transmission unit is an active IC tag that emits only an ID (unique ID) has been described above as an example. However, in the present invention, an active IC tag that transmits abnormality information indicating the type of abnormality together with a unique ID may be employed as the wireless transmission means.

  Such an IC tag has a memory, and may be configured to store abnormality information indicating presence / absence of abnormality or abnormality information indicating presence / absence and type of abnormality. The IC tag can be configured to rewrite the abnormality information in the memory when an abnormality is detected by the abnormality detection means, and to transmit the unique ID and the abnormality information wirelessly when the abnormality is rewritten. That's fine.

  The processing of the CPU 12a that has received the unique ID and abnormality information from such an IC tag is basically the same as the processing of only the unique ID, but the contents of the failure information list 20 and the search method are different. When the abnormality information is only the presence / absence of abnormality, for example, after the CPU 12a extracts only the ID indicating abnormality, the failure information list 20 similar to FIG. 3 is used by using the abnormality presence ID as a search key. The guidance may be selected. On the other hand, when the abnormality information indicates the presence or absence of abnormality and the type of abnormality, it is necessary to prepare a failure information list different from the failure information list 20 of FIG. For example, after the CPU 12a extracts only the ID indicating that there is an abnormality, the failure information list in which the abnormality type (and ID) and the guidance are associated with each other is referred to using the abnormality type (and ID with abnormality) as a search key. And guidance selection.

  Further, although an example has been described in which the IC tag that stores abnormality information and can be rewritten is an active type, in the present invention, a rewritable passive IC tag may be used. An example using a passive IC tag will be described with reference to FIG. FIG. 5 is a diagram illustrating a configuration example of a television apparatus according to another embodiment of the present invention. The television device 1 illustrated in FIG. 5 is different from the television device 1 of FIG. 1 in that each IC tag is a passive type, and the description of the overlapping parts is omitted.

  In the case of a passive IC tag, when the light receiving unit 13d receives a signal (abnormal information transmission request signal) generated as a result of pressing a dedicated key on the remote controller, the CPU 12a passes this signal through the light receiving unit 13d. Receive. When receiving the abnormal information transmission request signal, the CPU 12a instructs the receiving unit 12b, which is an IC tag reader, to read information, and the receiving unit 12b emits a radio wave for reading the information. In response to this, each IC tag transmits a unique ID and abnormality information, which can be received by the receiving unit 12b. Similarly, when the CPU 12a sends an abnormality information transmission request to the receiving unit 12b, which is an IC tag reader, at a predetermined timing such as periodically or when the power is turned on, the receiving unit 12b similarly receives the unique ID of each IC tag. And abnormal information can be received. As described above, the information output condition from the IC tag in this example includes a request from the remote controller via the CPU 12a and the IC tag reader, a request from the CPU 12a via the IC tag reader, and the like. Further, a configuration may be adopted in which an abnormality information transmission request is issued directly from the remote controller to the IC tag.

  In this way, when receiving a transmission request from the outside (such as an IC tag reader or a remote controller), each IC tag transmits a unique ID and abnormality information all at once (reply) as indicated by a dotted arrow in FIG. ) The receiving unit 12b, which is an IC tag reader, sequentially receives the ID and abnormality information transmitted at the same time and transmits them to the CPU 12a.

  When the CPU 12a obtains the ID and abnormality information for the IC tag mounted on the television device 1, the CPU 12a refers to the failure information list, reads the guidance for solving the failure, and notifies the subunit with the notification function. Give instructions. As a result, guidance notification according to a failure can be performed even if a passive IC tag is used. Note that even a passive IC tag requires a power source for rewriting abnormality information in the memory.
