Description

  The present invention relates to an information terminal device of an electric device system that notifies a user of an abnormality or failure of an electric device through an information terminal device that can be connected to a network, and a program thereof.

  Conventionally, this type of information terminal device and its program notify that an abnormality has occurred in the information terminal device when an abnormality or failure occurs in the electrical equipment, and the information terminal device is provided with the information terminal device that receives the notification. A notification screen for notifying the occurrence of an abnormality is displayed on the notifying unit, so that troubles of electrical equipment can be notified even at a remote location. In addition, even if the abnormality that has occurred so far has been resolved, the refrigerator will notify that the abnormality has been resolved, and when receiving the notification, the information terminal device will erase the screen that has been informed so far and perform normal processing. (For example, refer to Patent Document 1).

  FIG. 10 shows a conventional electric device (here, a refrigerator) described in Patent Document 1 and a device (abnormality detection device) for notifying an abnormality of the electric device. As shown in FIG. 10, the refrigerator 100 includes at least a fan motor (fan motor 101) that circulates cool air in the refrigerator, and an abnormality detection device 102 that detects abnormality of the refrigerator and notifies the refrigerator. The abnormality detection device 102 includes a current detection unit 103 and a notification unit 104.

On the other hand, an electrical equipment network is provided in which electrical equipment (such as a refrigerator, a washing machine, and an air conditioner) installed in each home is connected to an information terminal device and each electrical device is centrally controlled from the information terminal device. . In such a case, when an abnormality of the refrigerator 100 is detected by the abnormality detection device 103, the notification of the abnormality is made to the information terminal device while the notification is given by the notification unit 104, and the refrigerator 100 notifies the information terminal device that an abnormality has occurred. A service is provided in which an information terminal device notifies the occurrence of an abnormality.
Japanese Patent Laid-Open No. 10-259981

  However, in the above-described conventional configuration, when the electric equipment system including at least the information terminal device and the refrigerator 100 is restored after a power failure, that is, after the power is not supplied to the information terminal device and the refrigerator 100, the power supply is resumed. In this case, the information terminal device is equipped with a secondary battery that supplies power in the event of a power failure, while the program running on the information terminal device is not temporarily suspended. When the power failure occurs, the refrigerator 100 is not equipped with a power supply such as a secondary battery that supplies power at the time of the power failure, so the program operating in the refrigerator 100 stops. Then, when the power failure is restored and power is supplied again, the refrigerator 100 clears the current state and restarts the program. If an abnormality occurs again, the refrigerator 100 detects the abnormality and notifies the notification unit 104. Announcement of abnormalities in and notification to the information terminal device.

And a second network 250 connected to the information terminal device 200, and a server 300 connected to the second network 250.

  In the present embodiment, the refrigerator 100 is mainly described as an electric device. However, the network includes an air conditioner 120 and a washing machine 130 as the electric device. Note that the electric device is not limited to the refrigerator 100, and may be a home appliance or facility device such as an air conditioner 120, a washing machine 130, a microwave oven, or a water heater.

  As the first network 150, the electric device 100 and the information terminal device 200 in the same house use a wireless medium, and the electric device 100 and the information terminal device 200 are provided with wireless communication units 151 and 152, respectively. Specifically, an Echonet (R) home wireless network is assumed. In addition, although radio | wireless was used for the communication medium, you may be wired, such as power line communication which superimposes data on an electric wire or a power supply line.

  Assuming that the second network 250 is the Internet or a public line network, the server 300 installed outside the house and the information terminal device 200 are connected via the second network 250.

  In FIG. 2, the refrigerator 100 includes a power supply unit 111 that supplies power necessary for operation (mainly to cool foods and the like), a transmission / reception unit 112 that can be connected to the first network, and an abnormality detection that detects an abnormality. Control in which the information terminal device 200 is notified of an abnormality via the transmission / reception unit 112 when the unit 113, the notification unit 114, and the abnormality detection unit 113 detect an abnormality, and the notification unit 114 notifies the abnormality occurrence Unit 115 and storage unit 116. For all abnormalities occurring in the refrigerator 100 (abnormalities detected by the abnormality detection unit 113), a code (abnormal code) is assigned for each abnormality, and the storage unit 116 stores the generated abnormality in association with the abnormal code. ing. The notification unit 114 displays the abnormal code. In addition, about abnormality notification in the refrigerator 100 main body, you may make it reproduce | regenerate an audio | voice and a buzzer sound by the control part 115. FIG. In addition, when the abnormality detected by the abnormality detection unit 113 is resolved, the control unit 115 transmits a notification of abnormality cancellation to the information terminal device 200 via the transmission / reception unit 112 and notifies the notification unit 114 of the notification. finish.

  The information terminal device 200 includes a first transmission / reception unit 201 that can be connected to the first network, a second transmission / reception unit 202 that can be connected to the second network, and power necessary for operation. A power supply unit 203 to be supplied; a battery supply unit 204 that supplies power to the information terminal device 200 when power from the power supply unit 203 is interrupted; a power supply monitoring unit 205 that monitors at least the voltage of the power supply unit 203; An abnormality occurred in the refrigerator 100 received by the first transmission / reception unit 201 via the second transmission / reception unit 202 when the abnormality notification is received from the unit 206 and the refrigerator 100 via the first transmission / reception unit 201 The control unit 207 and the information that are transmitted to the server 300, receive the information transmitted from the server 300 and notify the user, and notify the notification unit 206. When the power supply source of the terminal device 200 is the power supply unit 203, a first state acquisition unit that acquires the state of the refrigerator 100 periodically (once every hour in the present embodiment) via the first transmission / reception unit It is comprised by 208.

  In the present embodiment, the power supply unit 203 converts the household power supply (AC100V) into a voltage (DC12V) necessary for the operation of the information terminal device 200 and supplies power. The monitoring unit 205 switches the power supply to the battery supply unit 204 when the voltage of the power supply unit 203 being monitored falls below a specified voltage value due to a power failure or the like, and power is supplied from the power supply unit 203 upon recovery from the power failure. If the specified voltage value is exceeded, the power source 203 is switched again.

  In the present embodiment, the notification unit 206 assumes a liquid crystal display (241 in FIG. 1) that displays a screen, and notifies the user of the information terminal device 200 of predetermined information on the screen. Further, the control unit 207 cancels the notification (notification) of the occurrence of the abnormality that has been notified by the notification unit 206 when the abnormality that has occurred in the refrigerator 100 is resolved and the information of the abnormality elimination is received from the refrigerator via the first transmission / reception unit. (In this embodiment, the abnormality notification screen is deleted).

  The server 300 includes at least a transmission / reception unit 301 that can be connected to the second network, and an abnormality notification information storage unit 302 that stores abnormality notification information notified by the information terminal device 200. It is assumed that the abnormality notification information storage unit 302 stores a word to be notified by the information terminal device 200 for each abnormality that occurs in the refrigerator 100.

  Next, the operation of the information terminal device 200 of the present embodiment will be described using the flowchart of FIG. In FIG. 4, the first transmission / reception unit 201 receives a notification of occurrence of an abnormality from the refrigerator 100 (S301) (more specifically, the abnormality detection unit 113 detects an abnormality in the refrigerator 100, and the control unit 115 transmits the transmission / reception unit 112 via the transmission / reception unit 112). And the first transmission / reception unit 201 receives the notification). If it does so, the control part 207 will inquire the abnormality code which generate | occur | produced with respect to the refrigerator 100, if this abnormality notification is received via the 1st transmission / reception part 201 (S302). When receiving the response to the inquiry in step (S302) (the abnormal code of the currently occurring abnormality) from the refrigerator 100 (S303), the control unit 207 is the abnormal code that is already reported by the notification unit 206. (S304), when an abnormal code that is not being notified is received, the abnormal code is transmitted via the second transmission / reception unit 202, and the server 300 is inquired for a word to be notified by the notification unit 206 (S305). And the 2nd transmission / reception part 202 receives the wording notified by the alerting | reporting part 206 from the server 300 (S306).

  As shown in FIG. 5A, the information transmitted to the server 300 in step (S305) is transmitted together with the abnormality code, the manufacturer code of the refrigerator 100 in which the abnormality has occurred, and the commodity code indicating the product number. The server 300 searches the abnormality notification information storage unit 302 for a word to be notified by the information terminal device 200 based on the transmitted abnormality code, manufacturer code, and product code, and transmits a corresponding word. In addition, the information received from the server 300 in step (S306) is the text corresponding to the transmitted information (abnormal code, manufacturer code, product code) described above and the length of the text. FIG. 5B shows the data.

  Next, the control unit 207 determines whether or not the length is 0 based on the length information received in step (S306) (S307), and the length of the word is 0 (or less than a predetermined value). ), The notification unit 206 does not notify the abnormality. When the number is 1 (or a predetermined value) or more, the message acquired by the notification unit 206 is notified (S308). If the processing from step (S304) to step (S308) is repeated for the number of times generated (S309), the user can be notified of the occurrence of an abnormality.

  FIG. 6 shows an example of a screen notified by the notification unit 206. The reason for canceling the notification of the abnormality that has occurred is that if the notification unit 206 informs the user of an abnormality that is not a problem as the original operation of the refrigerator 100 (for example, an abnormality of a device that is installed auxiliary at the beginning of sales), (This notification is not performed by the notification unit 114 of the refrigerator 100). In the present embodiment, the notification unit 206 determines whether or not to notify by the length of the wording, but information indicating whether or not to notify from the server 300 may be transmitted (for example, (The word information, the word length information, and the flag information indicating display / non-display are transmitted from the server 300).

  With the configuration as described above, when the information terminal device 200 notifies the abnormality that has occurred in the refrigerator 100, the abnormality that has occurred can be confirmed without being near the refrigerator 100, and the history of the abnormality that has occurred in the server 300 is managed. Therefore, by confirming the history information, the manufacturer of the refrigerator 100 can confirm the abnormality occurrence state, and the content notified by the notification unit 206 can be changed even after the refrigerator 100 is sold. .

  The information notified by the notification unit 206 is provided with a storage unit that stores the notification content in advance, so that the storage unit is read when an abnormality occurs, and predetermined information is notified by the notification unit 206. It doesn't matter.

  In addition, when the occurrence abnormality is resolved in the refrigerator 100 and the first transmission / reception unit receives a notification of the abnormality elimination, the abnormality notification notified by the notification unit 206 is stopped. However, when a power failure occurs before receiving the notification of abnormality cancellation, and the voltage value supplied from the power supply unit 203 by the power supply monitoring unit 205 becomes smaller than the specified value (S310), the power supply monitoring unit 205 The supply source is changed to the battery supply unit 204 (S311), the control unit 207 deletes the abnormality notification screen being notified by the notification unit 206 (S312), and the current notification unit 206 performs the processing of step (S312). By repeating the number of abnormalities being notified (S313), the abnormality notification screen can be deleted. On the other hand, in the refrigerator 100, when a power failure occurs, the power supply is cut off from the power supply unit 111, and thus the program of the operating refrigerator 100 is terminated.

  Furthermore, when the power failure is restored and the power supply from the power supply unit 203 is restarted again in the information terminal device 200, the power supply monitoring unit 205 detects that the voltage value supplied from the power supply unit 203 has become larger than the specified value ( In step S314, the power supply monitoring unit 205 changes the power supply source from the battery supply unit 204 to the power supply unit 203 (S315). On the other hand, in the refrigerator 100, the program that has been terminated because the power supply from the power supply unit 111 is resumed is started. At that time, the refrigerator 100 starts in an initialized state (a state in which no abnormality has occurred). However, since the program is started in the initialized state in the refrigerator 100 even though the abnormality has occurred, when the power failure is recovered from the occurrence of the power failure, the information terminal device 200 is resolved if the abnormality is resolved in the absence of anything. However, the notification of abnormality in the notification unit 114 ends.

  For this reason, even when the door opening abnormality (abnormality code: U10 in FIG. 3) is occurring and the power failure is recovered from the power failure, the abnormality notification state does not conflict between the refrigerator 100 and the information terminal device 200 (here The door opening abnormality is an abnormality that occurs only when the door is open for a certain period of time (N minutes or longer). That is, the same can be said for the abnormality that takes time to detect the abnormality regardless of the door opening abnormality.

  On the other hand, when an abnormality A (abnormal code: H01 in FIG. 3) occurs before the power failure and the power failure is restored (it does not take time to detect this abnormality), the refrigerator 100 once resolves the abnormality with the restoration of the power failure. Since the abnormality A is detected by the abnormality detection unit 113 after that, the abnormality notification is transmitted to the information terminal device 200, so the information terminal device 200 receives it via the first transmission / reception unit 201. If so (S316), the processing from step (S302) to step (S309) is performed.

  At the time of power failure recovery, communication between the information terminal device 200 and the electric equipment (air conditioner 120, washing machine 130) connected to the information terminal device 200 in addition to the refrigerator 100 is frequently performed. The first transmission / reception unit 201 may not be able to receive the abnormality occurrence notification. Therefore, at normal times (when the power supply source is the power supply unit 203) periodically (for example, once an hour) (S316), the first state acquisition unit 208 queries the refrigerator 100 for an abnormal state (S318). If it is in an abnormal state (S319), the processing from step (S302) to step (S309) is performed.

  In addition, when the information terminal device reports an abnormality (or failure) and recovers from a power failure, the information terminal device may transmit information indicating the abnormality content to the device side. The device side receives this information and detects the abnormal content with priority and in a short period of time. For example, the detection during opening of the refrigerator door is normally 20 seconds. Refrigerator that has been informed that the door is open before the power failure and that has received the information from the information terminal device at the time of power failure recovery, detects the opening of the door as 10 seconds, half of the normal time, and reports the abnormality in a short time. For example.

  In this way, the information terminal device that includes the battery supply unit and operates even during a power failure can be used as a backup for information during a power failure. The user can know the operating status / abnormal status of each home appliance before the power outage by using the information terminal device, and if necessary, the information terminal device can be operated to recover from the power failure. -It is also possible to perform a fault detection reservation operation.

  As described above, in the present embodiment, it is possible to prevent the abnormality notification state between the refrigerator 100 and the information terminal device 200 from being different by deleting the abnormality occurrence notification screen that is being notified when a power failure occurs.

In the present embodiment, the information terminal device 200 performs the following processing.
1. The first state acquisition unit 208 is provided, and the notification screen that has been informed so far when a power failure occurs or when a power failure is restored is deleted.
2. The refrigerator 100 is periodically inquired of the abnormal state.

However, the following process 3 may be newly performed without performing processes 1 and 2.
3. A second state acquisition unit that inquires the refrigerator 100 about the abnormal state once or multiple times only when the power failure is restored, and inquires whether or not the abnormality has occurred and whether or not the abnormality has been solved, and is newly generated. If there is an abnormality, the control unit 207 causes the notification unit 206 to notify the abnormality notification screen. If there is an abnormality that has been resolved, the control unit 207 deletes the abnormality notification screen.

(Embodiment 2)
7 to 9 are diagrams showing a second embodiment of the information terminal device according to the present invention. FIG. 7 is a functional block diagram showing the function of each component device of the system.

  In FIG. 7, the refrigerator 100 is provided with a storage unit 116 and an input unit 117 as compared with the first embodiment, and the information terminal device 200 can communicate with the refrigerator 100 and other electric devices (such as an air conditioner 120 and a washing machine 130). It is assumed that a device registration unit 209, a storage unit 210, an input unit 211, and a first setting information acquisition unit 212 are provided. The storage unit 116 stores screen setting information indicating whether or not to delete the abnormality notification screen when a power failure occurs or when the power failure is restored, and predetermined information set by the information terminal device 200.

  A device registration process that enables the device registration unit 209 to communicate with an electrical device (for example, the refrigerator 100) will be described.

  First, when both devices are set to the device registration processing mode so that the electric device 100 can communicate with the information terminal device 200, the device registration unit 209 assigns to the refrigerator 100 an identifier for identifying whether the electric device is communicable with itself. Allocate via one transceiver. The control unit 115 of the refrigerator 100 is stored in the storage unit 116. Thereafter, the transmitting / receiving unit 112 adds the allocated identifier to the information to be transmitted and transmits the information to the information terminal device 200.

  Further, the first transmission / reception unit 201 of the information terminal device 200 also determines whether or not the device is to be communicated based on this identifier (in the present embodiment, the refrigerator 100 necessarily communicates with the information terminal device 200). The determination of the identifier in the first transmission / reception unit 201 is not described).

  It should be noted that the reason why both devices enter the registration processing mode is that this processing is performed by inputting presets in the input units (117, 211) provided in both devices. When the registration processing mode is entered, the first setting information acquisition unit 212 acquires screen setting information stored in the storage unit 116 of the refrigerator from the refrigerator 100 and stores the information in the storage unit 210 of the information terminal device 200. .

  FIG. 8 shows screen setting information stored in the storage unit 210 (stored in the storage unit 116 of the refrigerator 100). As shown in FIG. 8, flag information indicating whether or not to delete the screen when a power failure occurs during the notification of the notification screen regarding the abnormality is stored in correspondence with the abnormality code.

  Next, processing for deleting the screen that is being notified to the notification unit 206 based on the screen setting information acquired during the device registration processing in the present embodiment will be described using the flowchart of FIG. Since the operation flow of the information terminal device 200 of the present embodiment is a part of the first embodiment changed, FIG. 9 shows only the changed portion. Note that the changed portion is replaced with the flow of FIG. 9 in the process of step S312 of FIG.

  When the power monitoring unit 205 changes the power supply source to the battery supply unit 204 in step (S311) of FIG. 3, the control unit 207 reads the screen setting information from the storage unit 210 (S312a), and the abnormality is about to be erased. It is determined whether or not the flag information of the screen setting information is deleted (S312b), and if it is deleted, the abnormality notification screen is deleted (S312c). This may be performed for the number of abnormalities being notified by the notification unit 206. In addition, although demonstrated also in Embodiment 1, you may make it perform the above processes at the time of a power failure restoration.

If only the device registration is stored in the storage unit 210 as in the present embodiment, the capacity of the storage unit 210 can be reduced.

  Note that this screen setting information is not acquired from the refrigerator 100 but may be acquired from the server 300 at the time of device registration (in this case, the information terminal device 200 includes a second setting information acquisition unit). Suppose). Then, the screen setting information can be changed even after the refrigerator 100 is sold. Further, whether or not to delete the notification screen at the time of power failure with respect to the abnormalities together with the words to be notified in the first embodiment when the notification to be notified by the notification unit 206 is acquired from the server 300 (step (S306) in FIG. 4) If it is made to acquire flag information which shows and memorize | stores in the memory | storage part 210, since it becomes unnecessary to memorize | store all the screen setting information which generate | occur | produces in the refrigerator 100 in the memory | storage part 210, the capacity | capacitance of the memory | storage part 210 can be made still smaller. (In this case, the information terminal device 200 includes a third setting information acquisition unit).

  In addition, the means described in the present embodiment cooperates hardware resources such as a CPU (or microcomputer), RAM, ROM, storage / recording device, electrical / information device including I / O, a computer, a server, and the like. You may implement with the form of a program. In the form of a program, new functions can be distributed / updated and installed easily by recording them on a recording medium such as magnetic media or optical media or distributing them using a communication line such as the Internet.

  As described above, in the information terminal device and the program according to the present invention, the abnormality information notified by the refrigerator and the abnormality information notified by the notification unit of the information terminal device connected by the home appliance network are restored to the power failure. Since it can be matched sometimes, it is useful not only for the refrigerator but also for notifying the occurrence of abnormality in home appliances such as air conditioners and washing machines. Moreover, it is useful not only for abnormalities but also for reporting the status of home appliances.
