Has become possible. Under such circumstances, a technique for confirming the state of each home appliance from a remote location away from the home appliance is desired.

On the other hand, in a computer system or the like, a notification function for notifying a user of the arrival of information such as an incoming mail or a notification from an accessed site is realized. For example, when an OS or an application detects an incoming mail, it notifies the user of the incoming mail through a user interface. When the OS of the computer system can provide the security information of the OS, the OS of the computer system notifies the user of the security information through the user interface. If the user permits when accessing the site, the browser application receives information such as new information from the site and notifies the user through the user interface.

However, since these notification functions are realized as functions of the OS and applications, it is necessary to implement as many as the number of notification targets. That is, it is technically complicated and difficult to implement in a wide variety of home appliances that are supposed to be used in the home.

As shown in FIG. 3, the air conditioner 12 includes its own identification information d0, a message d1, and a home appliance category d2 to which the air conditioner 12 belongs. The message d1 is information provided to the user such as an operating state, an operating state, and an error state detected by the state detection unit 102. The message d1 may be stored as a fixed phrase in a storage unit (not shown) in advance. In this case, the notification data generation unit 112 selects the corresponding standard message based on the operation state, operation state, error state, etc. detected by the state detection unit 102, and creates the notification data. Further, the message d1 may be a pre-encoded message. In this case, the message d1 contains only the code. The home appliance category d2 is information used by the event queue server 20 as reference information for determining the priority of notification data. The home appliance category d2 is defined by classifying, for example, the event generating device 10, and examples thereof include a washing machine 11, an air conditioner 12, a refrigerator 13, a television 14, and an electronic lock 15. That is, in the example shown in FIG. 3, the notification data of the content of the message "maintenance is completed" is shown for the home electric appliance of the identification information "13" belonging to the home electric appliance category "air conditioner".

The refrigerator 13 also has the same configuration as the air conditioner 12. That is, the refrigerator 13 includes a state detection unit 103, a notification data generation unit 113, and a notification data transmission unit 123. The state detection unit 103, the notification data generation unit 113, and the notification data transmission unit 123 have functions common to the state detection unit 102, the notification data generation unit 112, and the notification data transmission unit 122, respectively. In the case of the refrigerator 13, the operation information detected by the state detection unit 103 includes the power on / off state, the operation information includes the temperature inside the refrigerator and maintenance information, and the error information includes the presence / absence of an operation error.

(Configuration of event queue server 20)
As shown in FIG. 2, the event queue server 20 includes a notification data acquisition unit 200, an event queue management unit 210, an event queue database (DB) 220, an event data provision unit 230, a priority information database (DB) 240, and a priority. The granting unit 250 is provided.

The notification data acquisition unit 200 is an interface for acquiring notification data from an event generating device such as an air conditioner 12 or a refrigerator 13. The notification data acquisition unit 200 may receive the notification data sent by the push method from the air conditioner 12 or the refrigerator 13, or may read the notification data from the notification data acquisition unit 200 to the air conditioner 12 or the refrigerator 13 by the polling method.

The event queue management unit 210 stores the notification data acquired by the notification data acquisition unit 200 in the event queue database 220. The event queue management unit 210 and the event queue database 220 manage notification events as a listed event queue.

The event data providing unit 230 is an interface that provides an event queue such as an air conditioner 12 or a refrigerator 13 managed by the event queue database 220 to the display device 32 as event data. The event data providing unit 230 may provide the event queue stored in the event queue database 220 to the display device 32 by a push method, or may provide the event queue by a polling method in response to a request from the display device 32. May be good.

The priority information database 240 stores a definition table, a determination standard, and the like that define the priority displayed by the display device 32 for each of the notification data sent from the air conditioner 12 and the refrigerator 13. For example, among the event generating devices 10, there are home appliances (for example, electronic locks) whose event data to be transmitted always has a high priority, and home appliances categories (for example, air conditioners) that require time to recover in the event of a failure. .. The priority information database 240 stores a definition rule that defines the priority of such notification data. For example, an event that requires an external repair request is defined as priority 1, and an event belonging to the electronic lock category is defined as priority 2. The priority assigning unit 250 has a function of assigning priority information indicating a priority or the like to the event queue stored in the event queue database 220 based on the definition rule stored in the priority information database 250. .. That is, the event queue stored in the event queue database 220 is formed with priority information attached to each notification data.

FIG. 4 is an example of an event queue in which the event queue database 220 is accumulated. As shown in FIG. 4, the event queue includes elements such as a queue number d3, a priority d4, a display expiration date d5, an expiration date d6, identification information d0, a message d1, and a home appliance category d2.

The queue number d3 is a notification event number assigned in the order in which the notification events arrive at the event queue database 220 from the air conditioner 12 and the refrigerator 13. In FIG. 4, the notification data arrives in the order of the queue numbers d3 101, 102, 103 from the top. The priority d4 is information attached to each of the notification data and indicating the priority to be displayed. In the example shown in FIG. 4, they are represented by numbers such as 1, 2, 3, ... In descending order of priority. The display deadline d5 is information indicating the time (for example, expressed in seconds) for displaying the message d1 included in the corresponding notification data. The expiration date d6 is information indicating the time (for example, expressed in seconds) that the notification data should be stored as an event queue after arriving at the event queue database 220. In the example shown in FIG. 4, the queue number is "101", the message "normal operation" is received from the event generating device of the home appliance category "electronic lock" with the identification information "15", and the queue number "101". The event has a priority of "3", the display period is "5 seconds", and the time to be left in the event queue is "300 seconds" from the arrival.

The same applies to the notification data corresponding to other queue numbers. In the event queue shown in FIG. 4, the event of the home appliance category “refrigerator” of the identification information “13” that reaches the event queue database 220 third has the priority “1”. This indicates that the notification data from the refrigerator 13 arrives at the event queue database 220 later than the notification data received from the electronic lock 15. On the other hand, the priority of the notification data of the electronic lock 15 is "3", which is lower than the priority of the notification data from the refrigerator 13 "1". That is, it indicates that the event of the queue number "103" has a higher priority than the event of the queue number "101" and the event of the queue number "103" should be notified to the user in preference to other notification data. ..

(Configuration of notification display device 30)
As shown in FIG. 2, the display device 32 includes an event data acquisition unit 300, a state detection unit 310, an event data database 320, a display management unit 330, a display information generation unit 340, and a display unit 350.

The event data acquisition unit 300 is an interface for acquiring event data from the event queue database 220. The event data acquisition unit 300 may receive the event data sent from the event queue database 220 by the push method, or may periodically acquire the latest event data from the event queue database 220 by the polling method. The received event data is stored in the event data database 320.

The state detection unit 310 is a sensor that detects its own operating state. Based on the event data received from the event queue database 220, the display device 32 provides the user with information including the event data when the display device 32 is in a state where the information can be provided. For example, the state detection unit 310 detects that the display device 32 is in the power-off state, the maintenance mode state, and the like.

The event data database 320 stores event data acquired by the event data acquisition unit 300. The display management unit 330 is a calculation block that determines whether or not the event data accumulated in the event data database 320 is provided to the user according to the detection result of the state detection unit 310.

The display information generation unit 340 adds the event data accumulated in the event data database 320 to the video information and the like displayed by the display device 32. Specifically, the display information generation unit 340 adds event data to the video information by imposing a message at a specific position on the screen display in the video information.

The display unit 350 is a visual interface of the display device 32, and is a display typified by, for example, a liquid crystal display device. The display unit 350 displays an image / video based on video information, event data added by the display information generation unit 340, and the like.

FIG. 5 shows an example of how the display unit 350 displays event data. As shown in FIG. 5, the display unit 350 of the embodiment has a message display D1 indicating the message d1 included in the event data at a predetermined position of the display screen D0 (in the example shown in FIG. 5, the lower right corner of the display screen D0). , The category display D2 indicating the home appliance category d2 is displayed. In the example shown in FIG. 5, the message d1 "Error NO1 has occurred in the refrigerator" with the queue number d3 of "103" is displayed on the message display D1, and the "refrigerator" of the corresponding home appliance category d2 is displayed as a category. It is displayed as an icon on D2.

(Operation of event queue server)
Subsequently, the operation of the event queue server 20 will be described with reference to FIG. In the example described below, it is assumed that the notification data of the air conditioner 12 is provided to the user as the event generating device 10.

The notification data transmission unit 122 of the air conditioner 12 sends notification data as shown in FIG. 3, including "12" as the identification information d0, "maintenance completed" as the message d1, and "air conditioner" as the home appliance category d2. Upon sending to the queue server 20, the notification data acquisition unit 200 receives the notification data, and the event queue management unit 210 stores the received notification data in the event queue database 220 (S400).

As shown in FIG. 4, the event queue management unit 210 assigns "104" as a new queue number to the notification data from the air conditioner 12 acquired by the notification data acquisition unit 200 (S402).

Subsequently, the event queue management unit 210 determines whether the notification data from the air conditioner 12 acquired by the notification data acquisition unit 200 includes priority information (S404).

When the determination result notification data does not include the priority information (No in S404), the priority assigning unit 250 determines the priority of the notification data (S406). Examples of the criteria for determining the priority include a table in which the home appliance category d2 stored in the priority information database 240 is compared with the priority, a table in which the keyword included in the message d1 is compared with the priority, and the like. To. In the example shown in FIG. 3, since the notification data from the air conditioner 12 does not include the priority information, the priority assigning unit 250 determines the priority.

When the priority is determined, the priority assigning unit 250 adds priority information to the event queue stored in the event queue database 220 (S408). In the example shown in FIG. 4, the priority d4 "2" is added to the air conditioner having the identification information "12" of the queue number "104". In addition to the priority d4, the priority giving unit 250 may add the display deadline d5 and the expiration date d6 to the event queue as priority information. In the example shown in FIG. 4, the priority assigning unit 250 adds the display deadline d5 as “600 seconds” and the expiration date d6 as “3600 seconds” for the air conditioner having the identification information “12” of the queue number “104”. There is. The criteria for determining the display expiration date and the expiration date can be stored in advance in the priority information database 240.

The event queue management unit 210 generates an event queue to which priority information is added (S410). At this time, the event queue management unit 210 monitors the expiration date d6 included in the event queue, and deletes the notification data of the queue number whose expiration date d6 has passed since the notification data arrived. In the example shown in FIG. 4, the data having the queue number d3 of "101" is deleted from the event queue when 3600 seconds have elapsed from the arrival.

When the event queue is generated, the event data providing unit 230 provides the event queue stored in the event queue database 220 to the display device 32 as event data (S412).

As a result of the determination by the event queue management unit 210, when the notification data includes priority information (Yes in S404), the event queue management unit 210 generates an event queue (S410). For example, when the notification data emitted by the air conditioner 12 already contains priority information, the priority addition by the priority assigning unit 250 is omitted, and the already included priority information is used as it is in the event queue.

As described above, since the event queue server 20 and the home appliance network 1 of this embodiment add priority information to the notification data sent from the event generating device 10, the display device 32 controls the display using the priority information. Can be realized.

(Operation of notification display device)
Subsequently, the operation of the display device 32 will be described with reference to FIG. 7. In the example described below, it is assumed that the event data shown in FIG. 4, which includes the notification data of the air conditioner 12 as the event generating device 10, is provided from the event queue server 20.

The event data acquisition unit 300 periodically acquires event data from the event queue server 20 (S500). The event data may be acquired by receiving the data sent from the event queue server 20 by the push method, or may be acquired by the event data acquisition unit 300 by the polling method periodically. The event data acquisition unit 300 stores the acquired event data as an event queue in the event data database 320.

The state detection unit 310 detects the state of the display device 32 and sends the detection result to the display management unit 330 (S502). The display management unit 330 determines whether the display device 32 can provide information to the user (S504).

When it is impossible to provide information (No in S504) such as when the determination result display device 32 is not operating, the event data acquisition unit 300 waits for the next event data reception (S500).

If information can be provided (Yes in S504), such as when the determination result display device 32 is operating, the display management unit 330 determines whether the event queue is stored in the event data database 320 (S506).

When the event queue exists in the event data database 320 (Yes in S506), the display management unit 330 reads the event queue from the event data database 320 and reads the data of the queue number having the highest priority among the priority information (Yes). S508). In the example shown in FIG. 4, the queue number d3 is "103", the identification information d0 is "13", and the home appliance category d2 is "refrigerator", and the priority d4 of the notification data is "1". 330 selects the message d1 "Error NO1 has occurred in the refrigerator" of the queue number "103" and the home appliance category d2 "Air conditioner" as information to be provided.

The display information generation unit 340 adds the information of the message d1 and the home appliance category d2 selected by the display management unit 330 to the information displayed by the video information display device 32, and generates the display information displayed by the display unit 350. (S510). In the example shown in FIG. 5, the display information generation unit 340 superimposes the message "Error NO1 has occurred in the refrigerator" and the icon data corresponding to the home appliance category d2 "air conditioner" at a predetermined position on the display screen D0. Display information has been generated.

The display unit 350 displays the display information generated by the display information generation unit 340 on the display screen D0 (S512).

In the example of this embodiment, the display device 32 is limited in the number of messages that can be included in the display information, and can display only one message for the queue number. Therefore, only the information having the highest priority (or the information having the highest priority and the lowest value of the queue number) among the information included in the event queue is selected and displayed on the display unit 350. The display management unit 330 monitors the display deadline d5 included in the event queue (S514), and until the display time of the message d1 by the display unit 360 elapses the time indicated by the display deadline d5 (No of S514). , The display unit 350 maintains the display of the display information (S512).

When the display time of the message d1 by the display unit 350 has elapsed (Yes in S514), the display management unit 330 causes the display information generation unit 330 to stop displaying the message d1 and the home appliance category d2. (S516).

When the display of the displayed message d1 and the home appliance category d2 is stopped, the display management unit 330 deletes the information of the queue number for which the display has been stopped and changes the order of priority in the event queue (S518).

The display management unit 330 determines whether the event queue is stored in the event data database 320 (S506), and repeats the process until the information of all the queue numbers is displayed and deleted (S508 to S518).

If the event queue does not exist in the event data database 320 (No in S506), the operation ends.

As described above, the notification display device 30 and the home appliance network 1 of the embodiment provide the user with the notification data from the event generating device 10 by using the event queue to which the priority information indicating the priority order to be provided to the user is added. Therefore, even if notification data having different priorities are issued from a plurality of event generating devices, information can be provided to the user in an appropriate order.

In the display device 32 of the embodiment described above, the number of messages that can be included in the display information that can be displayed is limited, and only one message for the queue number can be displayed. Not limited to. It is possible to display a plurality of messages and display messages related to a plurality of queue numbers. In this case, the display management unit 330 selects a plurality of notification data based on the priority of the priority information, the value of the queue number, and the like.

In the embodiment described above, the notification display device 30 has been described as being a display device 32 typified by a television or the like, but the present invention is not limited thereto. Even if the notification display device 30 is, for example, a set-top box 31, the same effect can be obtained with the same configuration. In the case of the set-top box 31, the display unit 350 may be omitted and the display information generation unit 340 may be configured.

Further, in the embodiment described above, the embodiment has been described as constituting the embodiment by hardware elements, but the embodiment is not limited thereto. The embodiment may be realized by using a computer device. In this case, computer software that realizes the functions of the embodiment described above may be prepared, installed in a computer device, and executed.
