  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as embodiments) will be described in detail with reference to the accompanying drawings. In the subsequent drawings, the same numbers or symbols are assigned to the same elements throughout the description of the embodiments. In the functional configuration diagram, an arrow between functional blocks represents a data flow direction or a process flow direction.

(Basic concept)
FIG. 1 is a diagram showing a basic concept of a life watching system (hereinafter referred to as the present system) according to an embodiment of the present invention. In this system, a plurality of outlet adapters (hereinafter simply referred to as “adapter”) are installed between an electrical product at home such as an elderly living alone or a handicapped person and a wall outlet. A means for detecting on / off of a connected electrical product is embedded in the adapter, and information on the on / off status of the electrical product is notified to an external server via a home communication control device. It is like that. The indoor communication means between the adapter and the communication control device preferably uses power line communication (PLC), but other communication means such as Wi-Fi (registered trademark) may be used.

  In the database of the server, for each watcher (Hana and Gen in the example shown in the figure), multiple electrical appliances connected to multiple adapters in their homes and the on / off status of those electrical appliances Based on the detection information, a table for notifying a registered watcher's terminal (notification destination) according to notification conditions set in advance on the watcher side is stored. Here, the electrical product connected to the adapter does not require a special mechanism.

  The above notification conditions are registered in advance in the server by a watcher (family, helper, etc.), and can be easily changed depending on the life pattern of the watchee, seasonal variations, and the like. For example, if the watcher is “Hana”, the server will detect that the microwave or rice cooker has been turned off for 12 hours or more, or the air conditioner has been left for 48 hours or more. Is automatically sent to the watcher's terminal. The watcher knows that Hana is making daily meals using a microwave and rice cooker every day, so when both the microwave and rice cooker are off for more than 12 hours It is speculated that some sort of change is happening to Hana. In addition, if Hana knows that she has a habit of sleeping with the air conditioner turned off even in the summer, it is presumed that something unusual happened to Hana when the air conditioner was left on for more than 48 hours. Is done. However, on a hot day, it is possible to sleep with the air-conditioner on, so it cannot be judged as abnormal alone.

  Therefore, it is desirable that there are a plurality (at least three or more) of electrical appliances, that is, adapters, used for determining whether there is an abnormality or not in a state different from normal. Since the adapter itself is inexpensive, it may be considered that some administrative agencies distribute some adapters to the guardian's house. Of course, it is not necessary to use all of the distributed adapters, and the adapters need only be connected to electrical appliances that are useful for determining the watchful life of the watched person.

  There are many other appliances that can be used to determine watching, in addition to the above microwave ovens, rice cookers, and air conditioners. Information appliances such as electric kettles, televisions, refrigerators, and microwave ovens are already known. In either case, it is determined whether or not the electrical product itself is in an abnormal state or in a state different from normal (hereinafter referred to as an abnormal state). On the other hand, in this system, since an abnormal situation or the like is detected by the adapter and the server, it is not necessary to change the setting of each electrical product even if the watcher's life pattern changes.

  Since the electrical products that are useful for the monitoring of daily life vary from person to person and also vary depending on the season, region, etc., it is not preferable to leave such judgments uniformly to the electrical products as described above. It is important that the person can set the case flexibly. For example, “Gen-san” in the example in the figure is an old-fashioned person, a potter, and a person who rarely uses electrical products such as air conditioners and microwave ovens. For this reason, it is known that only electric scissors (hereinafter “lokuro”) are used. In such a case, this system can be used to watch over even a special item such as Rokuro. In addition, Gen has a personality that does not leave unused electrical appliances connected to the outlet. For example, he uses a fan in the summer and a kotatsu in the winter to connect to the outlet in the same room. However, even in such a case, if this system is used, only the notification condition is changed, so that it can be flexibly handled.

(Functional configuration)
FIG. 2 is a diagram illustrating an example of a functional configuration of the life watching system according to the embodiment of the present invention. Although only one adapter 20 is shown here in the watched person's home, in reality, a plurality (about 3 to 10) of adapters 20 are installed. The adapter 20 includes one or a plurality of outlet receptacles 21 (21A, 21B, etc.) for inserting a power plug of an electrical product, and a current amount detector 22 (22A, 22B, etc.) that detects the amount of current flowing through each outlet receptacle. ) And an outlet 23 in the wall.

  The current amount detection unit 22 is an ammeter that detects whether the current to the electrical product connected to the corresponding outlet receptacle 21 is on or off. Here, the off state does not necessarily mean that the flowing current is zero, and it is also determined that the current is off even when a weak current not more than a predetermined reference value (threshold value) is flowing. This is because, in order to shorten the start-up time when the power switch is turned on, many electric products continue to pass a standby current even when “the power is off”. Since the predetermined reference value of the weak current varies depending on the electric product, a plurality of adapters having different reference values for determining that the power is off may be prepared.

  The current amount detection unit 22 is an electrical product on / off detection means, and the detected electrical product on / off signal is connected to the PLC communication control via the power line via the wall outlet via the detected time. Sent to the device 30. PLC is a communication technology that uses a power line as a communication line, and is also called power line communication, power line carrier communication, power line communication, or PLT (Power Line Telecommunication). Since the PLC is a well-known technology, the description thereof is omitted here, but as described above, other communication means such as Wi-Fi (registered trademark) may be used instead of the PLC. The adapter 20 may have a function of measuring and outputting the amount of power consumed by the connected electrical product as an option for energy saving.

  The on / off information of the electrical product detected by the adapter 20 is finally obtained for each adapter (for each connected electrical product) via a public communication network such as the Internet or a dedicated line network in a nursing facility. Is transmitted to the server 40 (also referred to as a life watching server). As an example, the functional configuration of the server 40 includes an adapter registration unit 41, an adapter information DB 42, a reception unit 43, a notification condition determination unit 44, and a notification transmission unit 45.

  The adapter registration unit 41 is given a unique identifier (adapter ID) for each adapter 20 (more precisely, for each outlet receptacle 21 of the adapter), and is used as an alternative to the identifier of the electrical product connected to the adapter 20. It is done. However, since the adapter 20 does not have a function of identifying the type of connected electrical product, it is necessary for the watcher to manage which electrical product is connected (associated) to which adapter 20.

  The adapter registration unit 41 has a function of associating the adapter 20 with an electrical product and a function of setting a notification condition. The notification condition is to determine the abnormal situation of the watcher's house by recording the on / off information of the electrical product associated with the adapter 20, and notify the watcher's terminal (hereinafter, watcher terminal 50). The conditions for this are determined. The notification condition can be freely set on the watcher side, and details thereof will be described later.

  The adapter information DB 42 includes, for each adapter ID, an adapter registration table 42a that holds information for registering connected electrical products, and an adapter status table 42b that stores on / off information of electrical products detected by the adapter together with detection times. Storing. The adapter information DB 42 also stores a notification condition setting table 42c that holds notification conditions set by the watcher by the adapter registration unit 41. These tables will be described with reference to the tables shown in FIGS. Further, a specific example of the notification condition setting method will be described with reference to FIGS.

  The receiving unit 43 functions as a means for receiving the on / off information of the electrical product connected to each adapter 20 from the plurality of adapters 20 through the PLC communication control device 30 of the watched person's house together with the adapter ID. .

  The notification condition determination unit 44 has a function of determining whether or not the set notification condition is satisfied, and generating a message corresponding to the determination result in the watcher terminal 50 when it is determined that the notification condition is satisfied. The notification transmission unit 45 has a function of actually transmitting the message generated as a result of the determination by the notification condition determination unit 44 to the watcher terminal 50. A specific example of the notification at this time will be described with reference to FIG.

  FIG. 3 is a diagram showing a specific example of the adapter registration table 42a and the adapter state table 42b stored in the adapter information DB 42 according to the embodiment of the present invention. The adapter registration table 42a is a table for associating an adapter with an electrical product. In the illustrated example, a washlet is associated with the adapter 1, a fan is associated with the adapter 2, and a rocker is associated with the adapter 3. The adapter registration table 42a stores information on a set date (associated date) and whether the adapter is used as a notification condition. The set date is used for the adapter that has passed the predetermined period to notify the watcher of a message that periodically reviews the connection state.

  The adapter state table 42b is a table in which the time when the electrical appliance of each adapter is turned on, the time when it is turned off, and the ON time are recorded every day, and is recorded for each adapter for each pair of power on / off. The As the TOTAL ON time (or TOTAL OFF time), the total ON time (or OFF time) of the day is recorded and used for determining the notification condition. The adapter whose TOTAL OFF time remains off for a long period of time may not be connected to an electrical product, and therefore is also used to send a message to the watcher for periodic review.

  FIG. 4 is a diagram showing a specific example of the notification condition setting table 42c stored in the adapter information DB 42 according to the embodiment of the present invention. As shown in the figure, the notification condition setting table 42c stores a detection target electrical product, a notification destination, and a notification condition for each watched person. The detection target electrical product is an electrical product that is connected to the adapter and whose “Use for notification condition” column in the adapter registration table 42a in the previous figure is designated as “Yes”. Simply connecting to an adapter does not make it an electrical product to be detected. In the notification destination, the contact information (telephone number, mail address, etc.) of the watcher is stored. The notification condition stores a conditional expression including a power-on time or a power-off time of the detection target electrical product. For example, Hana ’s notification condition, “((1) ON + (2) ON) = 0hr / 24hr + (3) ON ≧ 48hr” is zero when the microwave or rice cooker is on for 24 hours Or when the air conditioner is on continuously for 48 hours or more. The notification condition input method will be described later.

  In this way, by holding the tables of FIGS. 3 and 4 in the server 40, the association between the adapter and the electrical product, the monitoring of the adapter state, the selection of the electrical product to be detected, and the conditions for notifying the watcher are established. It can be set flexibly.

  The above-described functional configuration of the present system is merely an example, and one functional block (database and function processing unit) may be divided, or a plurality of functional blocks may be configured as one functional block. Each function processing unit reads a computer program stored in a storage device such as a ROM (Read Only Memory), flash memory, SSD (Solid State Drive), or hard disk by a CPU (Central Processing Unit) built in the device This is realized by a computer program executed by the CPU. That is, each function processing unit reads and writes necessary data such as a table from a database (DB; Data Base or a storage area on a memory) stored in a storage device, and in some cases, related hardware It is realized by controlling hardware (for example, input / output device, display device, communication interface device), etc. The database (DB) in the embodiment of the present invention may be a commercial database, but is simply a table or file. The internal structure of the database itself does not matter.

(Screen example)
FIG. 5 is a diagram showing an example of a setting confirmation screen of the watching service registration screen according to the embodiment of the present invention. In the following description, it is assumed that a dedicated application for this system is installed in the watcher terminal 50. Hereinafter, the service provided by this system is referred to as a watch-over service.

  The setting confirmation screen 100 shown in the figure is a setting confirmation screen for confirming the setting after the setting by the watcher is completed. In this example, in Gen's house, the electrical appliances connected to adapter ID1, adapter ID3, and adapter ID4 are set as the home appliances to be detected, and the adapter ID1 is a toilet washlet, and adapter ID3 is a work room lock. The ID of the living room is set to be connected to the adapter ID4. Also, the installation location of the adapter may be registered in advance as shown in FIG.

  As shown in the figure, the conditional expression of the notification condition in the notification condition setting table 42c in the previous figure is converted into a natural language, and on the setting confirmation screen 100, the notification condition 105 is “Washlet operation frequency is 10 times / day, Or “Loco is off for 48 hours or more” is displayed. A plurality of notification conditions can be registered. In this example, “notification of fan operation number of 0 times 3 days” is registered as notification condition 106 which is another notification condition. Since the notification condition 106 can only be used in the summer, a notification condition 107 (“Kotatsu is ON for 48 hours or more”) is prepared for the winter. Gen said that he has a habit of switching between the electric fan and the kotatsu in the same outlet in the living room in summer and winter. However, the notification condition 105 that can be used regardless of the season is currently active (indicated by shading). In this way, by registering a plurality of notification conditions, the optimal notification conditions can be switched with one touch in accordance with the season, weather, region, etc. and the lifestyle of the watched person.

  Next, FIG. 6 is a diagram illustrating an example of an adapter setting screen of the watching service registration screen. The adapter setting screen 110 is a screen for associating an adapter, an electrical product connected to the adapter, and an installation location of the electrical product. In the electrical product association table 111, installation locations and connected electrical products are registered for all adapters installed in the outlets. As shown in the figure, a general electrical product icon list 112 is classified into general household appliances, seasonal household appliances, and healthy household appliances, and is displayed for each type.

The setter associates the adapter with the electric product simply by selecting the icon of the electric product actually used from the electric product icon list 112 and dragging and dropping the icon onto the electric product association table 111. be able to. In the example of the figure, a state in which a washlet is associated with the adapter ID1 installed at the outlet of the toilet is shown. However, it is assumed that a special electric product such as an electric locomotive is input by a setter in the connected electric product column of the electric product association table 111 by characters. For this input, voice input may be used in addition to key input.

  Further, the association between the adapter and the installation location can be easily performed by dragging and dropping the installation location icon list 113 to the electrical product association table 111. In this way, by using an operation screen having a GUI (Graphical User Interface) interface, the adapter, the electrical product connected to the adapter, and the installation location can be easily associated with each other.

  Further, FIG. 7 is a diagram showing an example of a notification condition setting screen of the watching service registration screen. The notification condition setting screen 120 shown in the figure is a screen for setting notification conditions for making a determination of notifying the watcher after setting the adapter setting screen 110 in the previous figure. On this screen, the previously set electrical product association table 111 is displayed. However, here, for convenience, connected electrical products associated with the adapter are numbered with parentheses.

  In the notification condition setting area 121 on the right side of the figure, notification conditions can be easily input as shown. The notification condition input here is encoded, converted into a conditional expression as shown in the notification condition of FIG. 4 and stored.

  FIG. 8 is a diagram illustrating an example of the watching service notification screen. The watching service notification screen 200 shown in the figure is a screen that displays the notification content transmitted to the watcher side. As already described, when the notification condition determination unit 44 of the server 40 determines that the adapter state recorded in the adapter state table 42b satisfies the conditions set in the notification condition of the notification condition setting table 42c. In addition, the notification content is monitored and transmitted to the person terminal 50 via the notification transmission unit 45. In the example of the figure, two notification conditions are satisfied at the same time. This notification may be transmitted not only to the watcher terminal 50 as text information but also to a registered telephone number by voice. Further, a button (phone icon in the figure) for making a call to the watched person's house immediately from this screen may be provided.

  In the above explanation, the main purpose is to monitor the abnormal situation of the watched person's house and notify the watcher side, but it is not abnormal, but it is also possible to monitor the watched person's going out and returning home. it can. For example, if you register a combination of electrical products (adapter) that normally turns off when you go out and turn it on when you go home, and set the notification conditions separately, the watcher can go out and go home Can be easily notified.

  Electric appliances suitable for such purposes include room lighting, televisions, air conditioners, electric fans, washing machines, and the like. Room lighting is an effective means of detecting going out, but outlets for room lighting are often embedded in the ceiling. For this reason, the installation of the adapter requires work. However, according to the present system, it is possible to detect that the watched person has gone out or returned home with a combination of on / off information of other electrical products. For example, if the TV or radio is switched off within a predetermined time (for a short period of time) except for bedtime, and the air conditioner or fan, or the electric kotatsu or electric stove is switched off, the user goes out. It can be determined that the possibility is high. The opposite is true when returning home. If the mobile phone or smart phone charger or watched person is a woman, a hair dryer or hair curler can be used for detection when going out. Such notification of going out and returning home does not have to be performed every time, but only going out and returning date and time for a certain period may be notified collectively. By doing in this way, the life pattern of a watched person can be grasped | ascertained with more information.

(Effect of embodiment)
According to an embodiment of the present invention, it is possible to provide a lifestyle monitoring system that does not require replacement of an electrical product, can be applied to various electrical products, and can flexibly cope with changes in the life pattern of a watched person. Can do. If PLC or Wi-Fi (registered trademark) communication means are installed, it is only necessary to install a plurality of adapters in the outlets of each room in the home and connect the electrical products to be detected to those adapters. .
