  A notification control method according to an aspect of the present invention is a notification control method used in a monitoring system that monitors a resident of a house and performs notification under a certain condition, and is installed in the house detected by a sensor. In the acquisition step according to the acquisition step of acquiring the stove information indicating the state of the stove and the position information indicating the location of the resident, and predetermined timing information indicating the correspondence between each of the plurality of positions and the notification timing And a control step for controlling so that notification is performed at a notification timing according to the location of the occupant when the stove is ignited based on the acquired stove information and position information. is there. The watching system is composed of one or more devices that can acquire the detection result of the sensor by communication. An object of control related to notification is, for example, a device (a terminal device, a device constituting a watching system, or the like) having a notification function (display function or the like). As a result, the notification timing can be changed depending on the location of the resident being watched over by the watch system, so appropriate timing information should be set so as not to place an excessive burden on the resident's family, guardian, etc. It may be possible to make a notification. The family is a person related to the resident and is not limited to the person living with the resident.

  In the control step, the control is performed by transmitting broadcast information at the broadcast timing so that a specific terminal device having a function of broadcasting information corresponding to the broadcast information received can be received. Also good. Thereby, for example, in a terminal device held by the family of a resident who is a watching target, notification is made at an appropriate timing according to the location of the resident.

  The notification control method may further include an update step of updating the content of the timing information by reflecting an operation on the terminal device that has received the notification information. Thereby, for example, the family of the resident to be watched over can operate the terminal device and update the timing information so that notification is made at an appropriate timing.

  Further, in the control step, the notification information is transmitted in such a manner that the notification information indicates a location of the resident at the notification timing, and the notification control method further includes: And a position display step for displaying the location of the resident based on the notification information. Thereby, for example, the family of the resident to be watched over can understand the location of the resident by the terminal device and can take appropriate measures (for example, telephone contact) as necessary.

  The notification control method may further include an image display step of displaying an image serving as a user interface for making a call to the resident in the terminal device. Thereby, for example, the family of the resident to be watched over can make a telephone contact quickly and easily as necessary using the terminal device.

  The position information acquired in the acquisition step is information determined based on a detection result of whether or not the resident is present in the room by sensors installed in each of the plurality of rooms in the house. Yes, the timing information includes a notification timing corresponding to a position of one of the plurality of rooms, which is later than a notification timing corresponding to a position of another room farther from the stove than the one room. It is information determined to indicate timing, and in the control step, when the resident is located in the one room when the stove is lit, it is more than when the resident is located in the other room. Alternatively, the control may be performed so that the notification is performed later. As a result, if the resident is in a room near the stove, the notification will be delayed because it is more likely to wait for the heating on the stove to finish than if it is in a far room, so confirmation of the family etc. It becomes possible to reduce the burden.

  Further, the position information acquired in the acquisition step is based on a detection result of whether or not the resident is present in the room by sensors installed in each of a plurality of rooms including a toilet in the house. In the control step, when the stove is lit, when the resident is in the toilet, the notification is not performed earlier than when the resident is in a room other than the toilet. The control may be performed as described above. As a result, if the resident is in the toilet, it will normally move to another room in a short time (for example, return to the original location), so it will not be notified earlier than other rooms. It is possible to reduce the burden of confirmation.

  Further, the position information acquired in the acquisition step is whether or not the resident is present in the room by a sensor installed in each of a plurality of rooms including a room in which the stove in the house is installed. It is information determined based on the detection result, the notification timing in the timing information is represented by an elapsed time from when the resident is no longer in the room where the stove is installed after ignition of the stove, In the control step, the stove is installed after the stove is ignited according to the notification time set in the timing information corresponding to the position corresponding to the location of the resident indicated by the position information. The control shall be made so that the notification is made when the resident is no longer in the room. It may be. As a result, when there is a resident in the vicinity of the stove, no notification is given, and the burden of confirmation for the family or the like can be reduced.

  The notification timing in the timing information is represented by an elapsed time from when the stove ignited, and in the control step, the timing corresponds to a position corresponding to the resident location indicated by the position information. The control may be performed such that the notification is performed when the elapsed time related to the notification timing defined in the information has elapsed since the stove ignited. Thereby, it becomes possible to notify according to the time since the stove ignited.

  Further, in the control step, the notification is performed in a manner representing one level of the plurality of levels, in which the high possibility of occurrence of a situation requiring confirmation for watching the resident is divided into a plurality of levels. The control is performed, and the timing information indicates a correspondence between the position and the notification timing for each of the plurality of levels, and the notification timing for each level corresponding to the same position is set to the high possibility of corresponding to the level. The higher the level, the slower the information may be. As a result, every time there is a high possibility that a situation that requires confirmation to watch over the residents will be notified, family members and others are likely to have a situation that requires confirmation. It is possible to take appropriate measures in consideration of

  Further, in the control step, the control of notification according to the timing information may be performed only for notification of a level different from the already notified level. Thereby, since notification is made in stages, it becomes possible for families and the like to take appropriate measures based on the stages.

  The monitoring system according to one aspect of the present invention is a monitoring system that monitors a resident of a house and performs notification under a certain condition, and corresponds to one or a plurality of sensors, a plurality of positions, and a notification timing. A storage unit for storing predetermined timing information indicating the position, the stove information detected by the sensor and indicating the status of the stove installed in the house, and the position information indicating the location of the resident In accordance with the acquisition unit and the timing information, based on the stove information and the position information acquired by the acquisition unit, when the stove is ignited, the notification is performed at the notification timing according to the location of the resident It is a watching system including the control part which controls as described above. Thereby, since the notification timing can be changed depending on the location of the resident, it may be possible to appropriately notify the resident's family and the like so as not to place an excessive burden.

  Further, the control program according to an aspect of the present invention is a control program for causing a computer in a monitoring system to watch a resident of a house and perform notification under a certain condition to execute a predetermined process. The acquisition step of acquiring the stove information indicating the state of the stove installed in the house and the position information indicating the location of the resident detected by the sensor, and the correspondence between each of the plurality of positions and the notification timing are shown. According to predetermined timing information, based on the stove information and position information acquired in the acquisition step, when the stove is ignited, notification is performed at a notification timing according to the location of the resident. A control program including control steps for controlling the control. With the computer installed with this control program, it is possible to realize appropriate notification that does not place an excessive burden on the resident's family or the like.

Accordingly, the numerical values, shapes, materials, components, component arrangement and connection forms, steps (steps) and order of steps, and the like shown in the following embodiments are examples and limit the present invention. is not. Among the constituent elements in the following embodiments, constituent elements that are not described in the independent claims can be arbitrarily added. Each figure is a mimetic diagram and is not necessarily illustrated strictly.

(Embodiment 1)
Hereinafter, a watching system 10 according to an embodiment of the present invention will be described.

(Constitution)
FIG. 1 is a system configuration diagram showing a watching system 10 according to the first embodiment.

  As shown in FIG. 1, the watching system 10 includes a server 100, a bridge 200, a terminal device 300, and networks 31 and 32.

  The monitoring system 10 analyzes the detection results of the sensors A to D in the house 20 to determine the timing of notification according to the room where the resident is present when the stove 21 installed in the house 20 is in an ignition state. The system for performing the notification control. For example, the resident of the house 20 is an elderly person living alone or living alone in the daytime. In this example, the watching system 10 watches the elderly person, and when an abnormality occurs in the elderly person's life, the family of the elderly person, etc. Notification is performed via the terminal device 300 such as a portable terminal owned by. The alert alerts the elderly family and others. Although only one terminal device 300 is shown in FIG. 1, a plurality of terminal devices 300 may exist. The stove 21 is, for example, a gas stove, but the heat source may be a fuel other than gas fuel, electricity, or the like. In the stove 21 that is heated by electricity, for example, a state in which water is heated to a boiling level is treated as an ignition state, and other states are treated as a fire extinguishing state.

  The sensor A is a sensor that detects whether or not a resident is present in the kitchen in which the stove 21 of the house 20 is installed, and transmits the detection result to the bridge 200 at a predetermined period (for example, 1 second). The sensor A is, for example, an infrared human sensor installed in a kitchen, but may be another sensor. For example, when a resident is present in the kitchen, the sensor A detects the resident and transmits an active state as a detection result. When the resident is not present in the kitchen, the sensor A is inactive (inactive as a detection result). ) Send status. Similar to the sensor A, the sensors B and C are human sensors installed in a living room and a toilet, for example. Sensor B detects whether or not a resident is present in the living room, and sensor C detects whether or not a resident is present in the toilet, and transmits the detection result to bridge 200. Here, the description will be made assuming that the living room 20 is a room close to the kitchen (for example, the living room is a room adjacent to the kitchen).

  The sensor D is installed near the stove 21 of the house 20, detects whether the stove 21 is in an ignition state (that is, a fire extinguishing state), and transmits the detection result to the bridge 200 at a predetermined period (for example, 1 second). It is a sensor. The sensor D is, for example, a thermal sensor, and when the stove 21 has a circuit for ignition control, a sensor configured to detect whether or not it is in an ignition state based on a control signal of the circuit. It may be. For example, the sensor D transmits an active state as a detection result when the stove is in an ignition state, and transmits an inactive state as a detection result when the stove is in a non-ignition state (fire extinguishing state). .

  The bridge 200 is a relay device that can communicate with each of the sensors A to D, receives a detection result transmitted from each sensor, and transfers the detection result to the server 100 via the network 31. The network 31 is a wide area network (WAN) including the Internet. The bridge 200 may include a router function, and may be configured to be connected to the network 31 via an external router device. For example, a sensor ID for identifying the sensor is added to the detection result transmitted from each sensor to the bridge 200. Hereinafter, the sensor IDs of the sensors A, B, C, and D are assumed to be A, B, C, and D, respectively.

  The server 100 is a computer that acquires detection results of the sensors A to D from the bridge 200 via the network 31, analyzes the detection results, and performs control for notification as necessary. The server 100 includes, for example, a memory, a storage device such as a hard disk device, a clocking mechanism such as a clock counter, a communication circuit, and a CPU (Central Processing Unit). This memory is a ROM (Read Only Memory) that holds programs and data in advance, a RAM (Random Access Memory) that is used to store data when the program is executed, and includes a non-volatile memory, for example. May be. The CPU controls each part of the computer by executing a control program stored in the memory, and performs notification control processing according to the notification control method. Through the notification control process, the server 100 determines notification timing as necessary, and transmits notification information to the terminal device 300 via the network 32 at the determined notification timing. The notification information is, for example, a character string, an image, or other information indicating that there is a possibility that a situation that needs to be confirmed in watching the resident of the house 20 has occurred.

  The terminal device 300 is a computer such as a smartphone, a mobile phone, or a tablet that includes a storage device such as a display and a memory, a communication circuit, and a CPU. The terminal device 300 has a function of receiving notification information from the server 100 via the network 32 and displaying information on a display based on the notification information.

  FIG. 2 is a functional block diagram of the server 100. The server 100 acquires the detection results of the sensors A to D of the house 20 from the bridge 200, determines the notification timing according to the room where the occupant is present when the stove 21 is in an ignition state, and provides notification information. Broadcast control is performed by transmitting to the terminal device 300. For this notification control, the server 100 includes an acquisition unit 110, a storage unit 120, a control unit 130, and an update unit 140 in terms of functions as shown in FIG.

  The acquisition unit 110 is realized by a CPU that executes a control program, a memory, a communication circuit, and the like. The acquisition unit 110 is detected by each sensor, and the position indicating the stove information indicating the state of the stove installed in the house 20 (whether it is in an ignition state) and the location (for example, the room where the occupant is located) of the house 20 It has a function to acquire information. Specifically, the acquisition unit 110 acquires the stove information and the position information by receiving detection results and sensor IDs of the sensors A to D of the house 20 from the bridge 200. The acquisition unit 110 transmits the acquired stove information and position information to the control unit 130. FIG. 3 is a diagram illustrating a sensor state change history. The sensor state change history includes, for the detection results transmitted from the sensors A to D as an example and received by the acquisition unit 110, the time when the detection result has changed, the sensor ID, and the change state that is the detection result after the change in order of time. Represents. In the example of FIG. 3, the resident of the house 20 enters the kitchen from 12:34 to boil hot water, ignites the stove, moves from the kitchen to the living room, and when the hot water is boiled (12:40) It shows the case where the stove is turned off again after returning to the kitchen. The acquisition unit 110 has an area for storing the last detection result of each sensor in the memory, and when the detection result from each sensor changes, the contents of the area are updated to indicate the change state. FIG. 4 is a diagram illustrating an example of the contents of a memory area in which the acquisition unit 110 stores the last detection result (that is, the current state) of each sensor as a sensor state. The example of FIG. 4 shows the sensor state at 12:41 of the example of FIG. The stove information is indicated by the current state of the sensor D. The position information is indicated by the detection results (that is, the current state) of sensors A to C installed in each of a plurality of rooms in the house 20 (each of the kitchen, the living room, and the toilet in this example). This information specifies whether the resident is located. The sensor state illustrated in FIG. 4 represents stove information indicating that it is not an ignition state, and position information indicating that the resident is in the kitchen.

  The storage unit 120 includes a storage area such as a memory, and stores predetermined timing information 40 indicating the correspondence between the position and the notification timing. The timing information 40 is information that is referred to in order to determine the timing at which the control unit 130 notifies during the ignition of the stove, that is, the timing at which the notification information is transmitted to the terminal device 300. Notification is made when a predetermined time corresponding to the position of the resident of the house 20 during ignition of the stove has elapsed. FIG. 5 is a diagram showing a configuration and example contents of the timing information 40. As shown in the figure, the timing information 40 is configured by associating a position 42 and a notification elapsed time 43 for each notification level 41. The notification level 41 indicates the high possibility of occurrence of a situation that requires confirmation when watching the resident in the watching system 10, and is expressed in one of three levels: “high”, “medium”, and “low”. Is done. The position 42 is represented by any of the kitchen, living room, toilet, and other rooms of the house 20. The notification elapsed time 43 indicates the elapsed time from the ignition of the stove to the notification timing. For example, the timing information 40 is set so that the notification timing is earlier than the kitchen at each notification level, as shown in the example of the content of FIG. That is, in the timing information 40, the notification timing corresponding to the position of one of the plurality of rooms is set to a timing later than the notification timing corresponding to the position of another room farther from the stove than the one room. As shown. In addition, when a resident is present in the toilet, it is determined that notification is not performed because it should return to another room in a short time. In addition, the timing information 40 is determined such that, for example, the notification timing at the same position is delayed as the notification level has a high possibility of occurrence of a situation that requires confirmation when watching the resident. Note that the notification information transmitted to the terminal device 300 may include information indicating the notification level, and the terminal device 300 may be controlled to perform notification in a manner representing the notification level. The timing information 40 is stored in the server 100 by, for example, collecting information from the family of the resident who is the target of the monitoring system and inputting the information through the input means by an administrator, an operator, or the like of the server 100. Yes. Note that the timing information 40 may be configured by a value determined in advance at the time of design without depending on an input by an administrator or the like.

  The storage unit 120 further stores notification destination information 50 indicating a notification destination such as an e-mail address and a telephone number in order to notify the terminal device 300 owned by a family, a guardian, or the like of a resident of the house 20. FIG. 6 is a diagram illustrating a configuration and content example of the notification destination information 50. As shown in the figure, the notification destination information 50 is information indicating the notification destination 52 for each terminal device holder 51. The terminal device owner 51 is a person who becomes a notification destination when there is a possibility that confirmation is required in order to watch over the resident of the house 20, and the notification destination 52 is a terminal such as the mail address of the person. This is information used to transmit broadcast information so that the device 300 can receive it. The notification destination information 50 is stored in the server 100 when, for example, an administrator, an operator, or the like of the server 100 inputs the information via the input unit in the same manner as the timing information 40.

  The control unit 130 is realized by a CPU that executes a control program, a clock mechanism, a communication circuit, and the like. The control unit 130 uses the stove information, the position information, the timing information 40, and the notification destination information 50 to perform notification according to the location of the resident (room where the resident resides) when the stove 21 is in an ignition state. It has a function of determining timing and transmitting notification information to the terminal device 300. For example, when the resident is in the kitchen when the stove 21 is lit, the notification timing is later than when the resident is in the living room (a room away from the stove 21 than the kitchen). Further, when the stove 21 is lit, no notification is given when the resident is in the toilet. In addition, when the resident is in the toilet, the control may be performed so that the notification is not performed earlier than when the resident is in a room (kitchen, living room, etc.) other than the toilet. The control unit 130 may perform notification control according to the timing information only for notification of a notification level that is different from the already notified notification level. For example, the control unit 130 may perform notification only in the order in which the notification level increases from “low” to “high” while the stove 21 is in the ignition state. When the notification of the notification level “low” is recognized, the owner of the terminal device 300 prepares for the notification of a higher notification level that should be received next, for example, occasionally checking the display of the terminal device 300 Measures can be taken. In addition, when the notification of the notification level “medium” is recognized, the owner of the terminal device 300 checks the display of the terminal device 300, for example, more frequently in preparation for the notification with the higher notification level that should be received next. Preparatory measures can be taken. Then, when the notification of the notification level “high” is recognized, the owner of the terminal device 300, for example, contacts the resident of the house 20 to be watched to check whether there is any danger or the like. It becomes possible to do. Note that the monitoring system 10 does not particularly prohibit the owner of the terminal device 300 from calling the resident to be monitored when the notification level is “low” or “medium”. Depending on the judgment of the owner, it is assumed that even if the notification level is “low” or “medium”, the resident is contacted by telephone.

  The update unit 140 is realized by a CPU that executes a control program, a communication circuit, and the like, and updates the contents of the timing information 40 stored in the storage unit 120 by reflecting an operation on the terminal device 300 that has received the notification information. It has a function. Specifically, when the terminal device 300 receives an operation and transmits information corresponding to the operation, the updating unit 140 receives the transmitted information and updates the timing information 40 according to the information.

  FIG. 7 is a functional block diagram of the terminal device 300. The terminal device 300 receives the notification information transmitted by the server 100 directly or indirectly, and displays the information on the display based on the notification information. A unit 320 and an operation receiving unit 330.

  The communication unit 310 is realized by a communication circuit or the like, and has a function of receiving notification information transmitted from the server 100 and transmitting information to the server 100 according to an operation accepted by the operation accepting unit 330.

  The display unit 320 is realized by a CPU and a display that execute a display control program and the like, and has a function of displaying a notification level and the like on the display based on the notification information. That is, the display unit 320 performs display in a manner corresponding to the notification level when the notification information indicates the notification level.

  The operation receiving unit 330 has a function of receiving an operation by the owner of the terminal device 300 for changing the notification timing and transmitting information corresponding to the operation to the server 100 via the communication unit 310. Note that the update unit 140 of the server 100 updates the timing information 40 in accordance with information according to this operation.

(Operation)
Hereinafter, the operation of the watching system 10 having the above-described configuration will be described.

  The sensors A to D in the house 20 transmit the detection result and the sensor ID to the bridge 200 at a predetermined cycle. The bridge 200 receives the detection result and the sensor ID and transfers them to the server 100.

  The server 100 performs the notification control process shown in FIG.

  FIG. 8 is a flowchart showing notification control processing by the server 100. The notification control process will be described below with reference to FIG.

  When the acquisition unit 110 of the server 100 receives the detection result and sensor ID of each sensor from the bridge 200, the acquisition unit 110 holds the sensor state (see FIG. 4), acquires the stove information and the position information, and transmits them to the control unit 130. (Step S11). Then, the processes in steps S11 to S19 are repeatedly executed.

  When the stove 21 changes from the fire extinguishing state to the ignition state with reference to the stove information, the control unit 130 to which the stove information and the position information are transmitted clears the record of the notified notification level (step S13). Measurement of elapsed time is started (step S14).

  Subsequently, the control unit 130 refers to the stove information and determines whether or not the stove 21 is in a fire extinguishing state (step S15). When not in the fire extinguishing state, that is, in the ignition state, the control unit 130 refers to the position information and the timing information 40, and the elapsed time for notification corresponding to the position of the resident has passed for the notification level higher than the notified level. It is determined whether or not (step S16). By clearing in step S13, the level that has already been notified is not recorded at first, and therefore the elapse of the notification elapsed time 43 corresponding to the notification level 41 of the timing information 40 being “low” is determined. Once the notification about the “low” notification level is made, only the notification level higher than “low” is notified.

  If it is determined in step S16 that the notification elapsed time corresponding to the resident's position has passed for a notification level higher than the notified level, the control unit 130 performs notification information transmission processing in the terminal device 300. Control is performed so as to be notified (step S17). Following the processing in step S17, the control unit 130 temporarily records the notified level in a memory or the like (step S18). Next, the control part 130 performs the timing information update process for updating the timing information 40 according to operation of the terminal device 300 (step S19).

  FIG. 9 is a flowchart showing specific contents of the above-described notification information transmission process (step S17).

  As shown in the figure, as notification information transmission processing, the control unit 130 first identifies notification information that is content to be transmitted in correspondence with the notification level (step S21). The control unit 130 may identify the notification information by newly generating the notification information or may select one of a plurality of pieces of information generated in advance as the notification information. In addition to indicating the notification level, the notification information may include content indicating the location of the resident based on the position information.

  Subsequently, the control unit 130 refers to the notification destination information 50, selects a notification destination that has not yet been notified (transmission of notification information) (step S22), and sets the selected notification destination (for example, a mail address). Broadcast information is transmitted (step S23). The transmission of the notification information is made so that the terminal device 300 can receive it. For example, if there is an access from the terminal device 300, the notification information is transmitted to a mail server having a function of transmitting mail to the terminal device 300. Note that the transmission of the notification information in step S23 may be direct transmission to the terminal device 300, for example, in addition to transmission to a server such as a mail server. The control unit 130 repeats the processing in steps S22 and S23 as long as there is a notification destination that has not yet been notified (step S24), and ends the notification information transmission processing. In terminal device 300 that receives the transmitted notification information, information to be notified (notification level, resident location, etc.) is displayed on the display based on the notification information. Further, when the terminal device 300 receives an operation to change the setting related to the notification level, the terminal device 300 transmits an instruction to change the notification level including the content to be changed to the server 100 (for example, returns as a mail).

  In the terminal device 300 that has received the notification information, the display unit 320 serves as a position display step for displaying the location of the resident based on the notification information, and a user interface for calling the resident. An image display step for displaying an image or the like is executed.

  FIG. 10 is a flowchart showing the specific contents of the above-described timing information update process (step S19).

  As shown in the figure, as the timing information update process, when the control unit 130 receives a notification level change instruction from the terminal device (step S31), the control unit 130 has the changed content indicated by the change instruction. The contents of the notification level 41, the position 42, and the notification elapsed time 43 of the timing information 40, which are the basis for determining the notification timing at which notification is performed in step S17, are changed (step S32).

  Hereinafter, the operation of the monitoring system 10 described above will be described with a specific example assuming movement of a resident of the house 20 at the time of stove ignition.

  FIG. 11 is a diagram illustrating a communication sequence in the sensors A to D, the bridge 200, the server 100, and the terminal device 300. Although the sensors A to D periodically transmit the detection results, the drawing shows only the case where the detection results have changed for the sake of convenience. Here, description will be made assuming that the timing information 40 is the content illustrated in FIG.

  First, the server 100 receives that the sensor A is in an active state indicating that a resident is present in the kitchen via the bridge 200 (sequence SEQ1). Then, the server 100 receives via the bridge 200 that the sensor B and the sensor C are in an inactive state where the occupant is not detected, and the sensor D is in an inactive state indicating that the stove is in a fire extinguishing state (sequence). SEQ2-4). Since the acquisition unit 110 of the server 100 sequentially acquires the sensor state by the notification control process (see FIG. 8) (step S11), at the time immediately after the sequence SEQ4, the server 100 is illustrated in FIG. The sensor status of the content is stored.

  Thereafter, when the resident ignites the stove, the detection result that the sensor D is in the active state is transmitted to the bridge 200, and the bridge 200 transfers the detection result to the server 100 (sequence SEQ5). Since the stove has changed to the ignition state (step S12), the control unit 130 of the server 100 clears the notified level record (step S12) and starts measuring the elapsed time by the time measuring mechanism (step S14).

  If the stove remains in the ignition state and the resident leaves the kitchen and moves to the living room, the sensor A transmits an inactive state indicating that no resident is present in the kitchen as a detection result (sequence SEQ6). ). Sensor B transmits as a detection result that it is in an active state indicating that a resident is present in the living room (sequence SEQ7). The server 100 receives the detection results transmitted in the sequences SEQ6 and SEQ7 from the bridge 200, and updates the sensor state stored in the memory area (step S11). At the time immediately after the sequence SEQ7, it is understood from the sensor state that the stove information is in the ignition state and the position information is located in the living room.

  If 10 minutes have passed since the stove was ignited while the resident was in the living room, the control unit 130 of the server 100 refers to the timing information (FIG. 5), and at the notification level “low” in the living room. It is determined that 10 minutes, which is the elapsed time for notification, has elapsed (step S16). That is, it is determined that the notification timing has arrived, and notification information transmission processing is performed (step S17). Thereby, notification information indicating that the notification level is “low” is specified, and the notification information is transmitted to terminal device 300 in accordance with notification destination information 50 (sequence SEQ8). Here, the notification information includes a notification level and position information (information indicating the position of the resident at the notification timing).

  In the terminal device 300, the notification information is received by the communication unit 310, and the contents (notification level, resident position, etc.) according to the notification information are displayed on the display by the display unit 320. FIG. 12 is a diagram showing an example of a screen displayed on the display of the terminal device 300 corresponding to the sequence SEQ8. As shown in the figure, the terminal device 300 notifies (displays) that the level that requires confirmation for watching is “low” level on the screen including the watching information display 91a. On the screen of FIG. 12, buttons 92 a and 92 b for an operation of whether to change the notification timing are displayed. When receiving an operation for changing the notification timing, the operation receiving unit 330 of the terminal device 300 performs an operation related to a timing information change instruction as illustrated in FIG. 13 following the screen illustrated in FIG. 12. Display the screen to accept. In addition to the display 92 indicating that the operation for changing the notification timing can be performed, this screen represents the change contents of the notification timing, and buttons 93a to 93d for performing an operation for changing, and an operation for not performing the change. A button 93e is included. When the change instruction is operated, terminal apparatus 300 transmits information related to the change instruction to server 100 through communication unit 310 (sequence SEQ9). When the information related to the change instruction is received, the update unit 140 in the server 100 updates the timing information 40 according to the information related to the change instruction.

  The monitoring system 10 that operates as described above suppresses frequent notifications when a resident moves to a room near the stove for a short time and waits while listening to the state of the stove. Moreover, according to the monitoring system 10, by performing notification at an appropriate timing, the person who has received the notification can contact the resident by telephone or the like. For this reason, it is possible to suppress a situation in which the resident moves to a room far away from the stove and does not return to the kitchen for a long time while the stove is lit.

(Other embodiments, etc.)
As described above, the monitoring system 10 including the server 100 has been described according to the first embodiment. However, the above-described embodiment is merely an example, and it is needless to say that various modifications, additions, omissions, and the like are possible.

  The server 100 of the monitoring system 10 may change, add, or omit the content of the notification information transmitted to the terminal device 300. For example, the notification information indicates the notification level but does not indicate the position of the resident. good. In this case, for example, a screen as illustrated in FIG. 14 can be displayed on the display of the terminal device 300 corresponding to the sequence SEQ8 described above. The screen shown in the figure shows that the degree of confirmation required for watching is “low” level by the watching information display 91b. Note that, unlike the screen shown in FIG. 12, the screen shown in FIG. 14 does not include a button for an operation for changing the notification timing. As in the example of the screen illustrated in FIG. 14, the terminal device 300 may not particularly accept an operation for changing the notification timing. Thus, if the notification timing change instruction is not given from the terminal device 300, the updating unit 140 of the server 100 is unnecessary. The notification information may include a part of timing information 40 (for example, an elapsed time for notification) related to the notification timing, and correspondingly, the terminal device 300 displays a part of the timing information 40. It is also good.

  Corresponding to the sequence SEQ8 described above, the terminal device 300 may display a screen illustrated in FIG. 15 on the display. The screen shown in FIG. 15 makes it possible to select whether or not to make a telephone contact by using the watch information display 91c and the buttons 92c and 92d. In this case, when the button 92c is selected, the terminal device 300 displays a screen including a display 94 for inquiring about a telephone number of a call destination and buttons 95a and 95b indicating telephone number options, as illustrated in FIG. It may be displayed. The terminal device 300 displays the buttons 95a and 95b with reference to a telephone book or the like registered in advance in an internal storage device. For example, when the button 95a is selected, the terminal device 300 performs a telephone call.

  In the first embodiment, the server 100 performs the process (notification control) related to the monitoring of the resident for one house 20, but the server performs the notification control regarding the monitoring of the resident of each of the plurality of houses 20. 100 may do. That is, the bridges 200 of each of the plurality of houses 20 can be connected to one server 100, and the server 100 determines the location of each house 20 during ignition of the stove of the resident of the house according to the sensor in the house. The corresponding notification control may be performed. When the resident of each of the plurality of houses is to be watched over, the server 100 receives identification information that can be used for identifying the house from the bridge 200 of each house, and searches and extracts information necessary for each house. In order to facilitate the processing, the information in the storage unit 120 may be stored as a database in association with the identification information.

  Moreover, the watching system 10 shown in Embodiment 1 is good also as what is comprised including each sensors, such as sensor AD.

  In the first embodiment, an example in which sensors such as human sensors are installed in the kitchen, living room, and toilet of the house 20 is shown. However, the resident is located in a room other than the kitchen, living room, and toilet, or in other places. You may install sensors, such as a human sensor for detecting. In this case, the position information acquired by the acquisition unit 110 of the server 100 described above is information that can indicate that a resident is present in a room other than the kitchen, the living room, and the toilet. The acquisition unit 110 indicates the position of the resident detected by a system that identifies the location of the resident by wireless communication with a communication device carried by the resident of the house (a system that functions as one sensor). The position information may be acquired.

  The stove 21 may have a function of automatically extinguishing when the ignition state continues for a predetermined long time (for example, 1 hour) or longer. Alternatively, when the server 100 detects that the ignition state has continued for a predetermined long time (for example, 1 hour), a control signal instructing fire extinguishing may be transmitted to the mechanism that extinguishes the stove 21. Note that the notification elapsed time in the timing information shown in FIG. 5 is shorter than the predetermined long time.

  In the first embodiment, the server 100 performs the notification only in the order in which the notification level increases from “low” to “high” while the stove is in the ignition state. However, the notification level that is the same as or lower than the notification level already notified by the server 100 may be performed. Further, in the server 100, the notification may be performed only when the notification level is equal to or higher than a certain value (for example, “medium” and “high”), and the certain value may be set arbitrarily.

  Further, instead of displaying the information on the display based on the notification information, the terminal device 300 may output the information by voice through a speaker, or may output the information by printing. Moreover, the terminal device 300 may emit light when receiving notification information.

  Further, the terminal device that receives the notification information from the server 100 and displays the information according to the notification information, such as the terminal device 300 shown in the first embodiment, is a resident (for example, a resident of the house 20 to be watched over). It may be a terminal device owned by an elderly person) or a neighbor of the house 20. In addition to the terminal device 300, a lighting device installed inside the house 20 or outside the house 20 can be used as a device that receives the notification information from the server 100 and performs notification. In this lighting device, for example, the notification level is “high” in accordance with the notification level included in the notification information (a level indicating the possibility of occurrence of a situation that requires confirmation for watching the resident). For example, the emission color may be switched to red for “middle” or yellow for “medium”.

  The network 31 shown in the first embodiment may be a local area network (LAN). The server 100 may be located inside or outside the house 20. The server 100 executes a notification control method to control a device having a notification function to perform notification, and also performs notification control of the portion that the server 100 has a notification function (such as a display). You may control and alert | report by a method.

  In addition, the sensor state change history (see FIG. 3) is stored in a storage device such as a memory by associating the acquisition time with the timing mechanism for the detection results of each sensor received by the acquisition unit 110 shown in the first embodiment. It is also good. The stored sensor state change history can be used for detailed analysis of the detection result of each sensor.

  Further, in the first embodiment, measurement of elapsed time is started when the stove 21 is changed from the fire extinguishing state to the ignition state by the notification control process (FIG. 8), and notification is made when the notification elapsed time 43 has elapsed. did. Instead of when the stove changes to the ignition state, the elapsed time measurement start condition is changed, for example, when the resident is no longer in the room where the stove is installed after the stove is in the ignition state (the stove is installed Or if the resident is away from the room. In this case, the elapsed time related to the notification timing set in the timing information 40 corresponding to the location of the resident indicated by the location information is present in the room where the stove is installed after the stove is ignited. Broadcast information is transmitted when it has passed since it disappeared. Thus, even if the notification timing is expressed by the timing information 40 (elapsed time 43 for notification) as the elapsed time since the stove was ignited, the resident is located in the room where the stove was installed after the stove was ignited. It may be expressed by the elapsed time from the time when it stops.

  Further, the bridge 200 shown in the first embodiment may transfer data to the server 100 only when the detection result from each sensor has changed. The bridge 200 may transfer the detection result to the server 100 by adding time information indicating the reception time of the detection result from each sensor. Thereby, even if the order received by the server 100 of each detection result is different from the transmission order due to the influence of the condition of the communication path, the sensor state is properly grasped by arranging the order based on the time information. It becomes possible.

  In addition, in the timing information update process (step S19) shown in the first embodiment, the learning result is reflected and the timing is appropriately reflected by finding a certain tendency in the operation for updating by the terminal device 300 by machine learning. Information 40 may be set to optimize the notification timing. For example, if the sensor E detects the location in a room where work is concentrated, the notification level is set to “low” in 10 minutes in advance for the room corresponding to the sensor E. In the case where the person who has received the notification changes to 15 minutes or the like at a certain high frequency, the setting can be changed to 15 minutes by machine learning.

  Moreover, although Embodiment 1 demonstrated using the example where the monitoring system 10 is used in order to watch an elderly person, the resident of the house used as a watching target is not restricted to weak people, such as an elderly person, The person who is not a weak person It may be any person.

  Further, the execution order of the processing procedure (the procedure shown in FIGS. 8 to 10 and the like) by the server 100 is not necessarily limited to the order as described above, and the execution order is changed or a part thereof is omitted. You can do it. Further, all or part of the processing procedure (the procedure shown in FIGS. 8 to 10, etc.) may be realized by hardware or may be realized by using software. Note that the processing by software is realized by a CPU included in a computer executing a control program stored in a memory. Further, the control program may be recorded on a recording medium and distributed or distributed. For example, by installing the distributed control program in a computer and causing the CPU to execute it, it is possible to cause the computer to perform all or part of the processing procedures shown in FIGS.

  Further, a part of the processing (notification control processing or the like) by the server 100 described above may be shared by an external device (for example, another server or the like) that can communicate with the server 100.

  In addition, embodiments realized by arbitrarily combining the constituent elements and functions described in the above-described embodiments are also included in the scope of the present invention.

  The present invention can be used in a system for watching a person using a stove.
