Mode for Carrying Out the Invention

[0015] Configuration FIG. 1 is a diagram showing an example of the configuration of the monitoring system 10 according to the embodiment. The monitoring system 10 provides a monitoring service for monitoring abnormalities such as intrusion into a monitoring target area where a target person is located, and a watching service for watching the situation of a target person such as an elderly person.

[0016] The monitoring system 10 includes a plurality of sensors 100, a controller 200, a setting unit 300, a server device 400, and a plurality of terminal devices 600. The plurality of sensors 100, the controller 200, and the setting unit 300 are installed in a monitoring target area such as a residence of a target person and are connected via a communication network 11 such as a LAN (Local Area Network). The server device 400 is installed in a monitoring center operated by a business operator that provides a monitoring service and a watching service. The plurality of terminal devices 600 are each used by a target person and a watcher. The controller 200, the server device 400, and the terminal devices 600 are connected via a communication network 12 including the Internet and a mobile communication network.

[0017] The plurality of sensors 100 detect the situation of the target person in the monitoring target area and output detection information indicating the detection result. Further, at least a part of the plurality of sensors 100 detects an intruder into the monitoring target area and outputs detection information. When the monitoring target area is a residence, the plurality of sensors 100 include sensors 100 installed indoors in the residence (hereinafter also referred to as "indoor sensors 100") and sensors 100 installed outdoors in the residence (hereinafter also referred to as "outdoor sensors 100"). The indoor sensors 100 are installed, for example, at openings such as entrance doors and windows, at flow line parts such as passages in the residence, and in living rooms. The outdoor sensors 100 are installed, for example, in a garden and on a gate. In one example, the plurality of sensors 100 include window / door sensors, human presence sensors, TOF (Time Of Flight) sensors, ultrasonic (millimeter wave, microwave) sensors, and lighting / home appliance operation detection sensors.

[0018] The window / door sensor is installed at openings such as the front door, windows, and door leaves, and detects the opening of opening and closing bodies such as doors and windows. Examples of window / door sensors include a sensor that detects the opening of a door by detecting a change in magnetic field, and a sensor that detects the opening of a door by turning on / off a tamper switch. The human presence sensor, also called a space sensor, is installed in traffic flow areas and living rooms and detects the presence of people. Examples of human presence sensors include a sensor that detects the presence of people based on fluctuations in heat rays, a sensor that detects the presence of people by sound waves or high frequencies, a sensor that detects the presence of people from an input image, and a sensor that detects the presence of people when the incident light from a light projecting unit is blocked. In addition to the uses of human presence sensors, TOF (Time Of Flight) sensors and ultrasonic sensors are installed in traffic flow areas and living rooms and detect the postures of target persons. The lighting / home appliance operation detection sensor detects operations on home appliances. The lighting / home appliance operation detection sensor may be provided on a home appliance and detect an operation performed using an operation button of the home appliance. Alternatively, the lighting / home appliance operation detection sensor may be installed at a location where it can receive an operation signal transmitted from a remote controller to a home appliance, and detect an operation on the home appliance based on this operation signal. Examples of home appliances include television receivers, lighting equipment, air conditioners, heating appliances, fans, electric kettles, radios, water supply, gas, and electricity. For example, when it is detected that the television has been operated, the movement (situation) of the target person turning on the television in the living room can be detected from the location where the television is installed (such as the living room) and the time of operation. Further, as a sensor for monitoring purposes, a sensor that detects the usage amounts of lifelines such as water supply, gas, and electricity may be used.

[0019] The controller 200 monitors for intrusion into the monitored area where the subject is located using the sensor 100. The controller 200 is an example of the "security device" according to the present invention. For example, when an intruder is detected by the sensor 100, the controller 200 notifies the server device 400 that an intruder has entered the monitored area. The controller 200 has three security modes: an unmanned security mode, a manned security mode, and a release mode. Further, the controller 200 performs processing for watching over the subject. For example, when the period during which no detection information is output from the sensor 100 continues for a predetermined time, the controller 200 notifies the server device 400 that the subject has not moved for a predetermined time. These notifications are realized, for example, by transmitting an abnormal signal.

[0020] The unmanned security mode is a security mode for monitoring the entire monitored area. The unmanned security mode is used when the subject goes out and the monitored area is unmanned. In the unmanned security mode, when detection information of the sensor used for intrusion monitoring among the plurality of sensors 100 is output, an abnormal signal is transmitted from the controller 200 to the server device 400. When the unmanned security mode is set, for the sensor 100 that monitors the subject's leaving route, it is preferable to start detecting an intruder after a predetermined time has elapsed since the unmanned security mode was set, so as not to misdetect the subject going out as an intruder.

[0021] The manned alert mode is a security mode that monitors a part of the monitored area. The manned alert mode is used when a subject is present in the monitored area and an intruder is monitored in a part where the subject is not present. For example, in the manned alert mode, a predetermined outer perimeter area such as a front door, a window, a gate, or the outside of a residence is monitored to detect an intrusion into the monitored area from the outside. Alternatively, an area designated by an operation of a subject out of a plurality of areas included in the monitored area may be monitored. In the manned alert mode, when detection information is output from a sensor 100 used for intrusion monitoring installed in the outer perimeter area or a designated area (e.g., the second floor), an abnormality signal is transmitted from the controller 200 to the server device 400. On the other hand, even if detection information is output from a sensor 100 installed in a place other than the outer perimeter area or the designated area, this detection information is ignored, and an abnormality signal is not transmitted from the controller 200 to the server device 400. In the following description, the manned alert mode and the unmanned alert mode are collectively referred to as "alert mode".

[0022] The release mode is a security mode that does not monitor the monitored area. The release mode is used when there is a target person in the monitored area and there is no need to monitor for an intruder. In the release mode, monitoring for an intruder in the monitored area is not performed, and even if detection information is output from the sensor 100, this detection information is ignored and no abnormality signal is sent from the controller 200 to the server device 400.

[0023] The setting unit 300 accepts an operation to set the security mode of the controller 200. For example, the setting unit 300 is installed at the entrance of a residence, and is used to set the security mode when going out or returning home.

[0024] When the server device 400 receives an abnormal signal from the controller 200, it outputs information about the monitoring target area and the target person, thereby prompting the controller of the monitoring sensor to confirm with the target person or the security guard who rushes to the monitoring target area to take appropriate action. In addition, as part of the monitoring service or the watching service, the server device 400 can review and consider whether the security mode is being appropriately used, and provides information indicating the usage status of the security mode to at least one of the terminal device 600 used by the watcher and the terminal device 600 used by the target person.

[0025] The terminal device 600 is used for the target person or the watcher to view various information related to the monitoring service or the watching service. Examples of the terminal device 600 include a smartphone, a mobile phone, a personal computer, a tablet terminal, and a wearable terminal.

[0026] FIG. 2 is a diagram showing an example of the configuration of the controller 200. The controller 200 includes a control unit 201, a storage unit 202, a communication unit 203, an operation unit 204, a display unit 205, and a sounding unit 206. Each part of the controller 200 is connected via a bus.

[0027] The control unit 201 is a processor that controls each part of the device itself and performs various processes. For example, the control unit 201 includes a CPU (Central Processing Unit). The storage unit 202 is a memory that stores programs and various data for realizing the functions of the device itself. The data stored in the storage unit 202 includes information indicating the currently set security mode and an authentication code required for the security mode setting operation. For example, the storage unit 202 includes at least one of a ROM (Read Only Memory), a RAM (Random Access Memory), an HDD (Hard Disk Drive), and an SSD (Solid State Drive). The communication unit 203 is a communication interface for connecting the device itself to the communication networks 11 and 12. The communication unit 203 is used to communicate with other devices connected via the communication network 11 or 12.

[0028] The operation unit 204 receives various operations on the own device. The operations received by the operation unit 204 include an operation for setting the security mode and an operation for reading an authentication code from an authentication medium. For example, the operation unit 204 includes a touch sensor that receives operations on the screen of the display unit 205, an operation button that receives the setting of the security mode, and a reading device that reads an authentication code from an authentication medium such as an IC card held by the target person. The display unit 205 displays various information. The information displayed by the display unit 205 includes the currently set security mode, the state of the sensor 100, and information indicating the installation location of the sensor 100. For example, the display unit 205 includes a liquid crystal display. Further, the display unit 205 may be configured as a touch panel in combination with the touch sensor. The sounding unit 206 outputs various sounds such as a sound for notifying the occurrence of an abnormality and a message voice. For example, the sounding unit 206 includes a speaker.

[0029] The control unit 201 functions as an acquisition means 211, a setting means 212, and a transmission means 213. These functions are realized by the control unit 201 executing a program stored in the storage unit 202, the control unit 201 performing calculations or controlling each part of the controller 200.

[0030] When an operation for setting the security mode is performed using the setting unit 300, the acquisition means 211 acquires operation information indicating this operation.

[0031] The setting means 212 sets one of a plurality of security modes according to the operation of the target person. When an operation for setting the security mode is performed using the operation unit 204, the setting means 212 sets the security mode corresponding to this operation. When an operation for setting the security mode is performed using the setting unit 300, the setting means 212 sets the security mode corresponding to the operation information acquired by the acquisition means 211.

[0032] The transmission means 213 transmits the security mode information indicating the security mode set by the setting means 212 to the server device 400. The security mode information includes information indicating the type of the set security mode and the setting date and time of the security mode.

[0033] FIG. 3 is a diagram showing an example of the configuration of the server device 400. The server device 400 includes a control unit 401, a storage unit 402, and a communication unit 403. Each part of the server device 400 is connected via a bus. The control unit 401, the storage unit 402, and the communication unit 403 are basically the same as the control unit 201, the storage unit 202, and the communication unit 203 of the controller 200, respectively. However, the communication unit 403 is a communication interface for connecting the own device to the communication network 12 and is used to communicate with other devices connected via the communication network 12.

[0034] The control unit 401 functions as an acquisition means 411, a calculation means 412, and a transmission means 413. These functions are realized by the control unit 401 executing a program stored in the storage unit 402, performing calculations by the control unit 401, or controlling each part of the server device 400.

[0035] The acquisition means 411 acquires the security mode information from the controller 200. This security mode information constitutes the setting history of the security mode.

[0036] The calculation means 412 calculates the total usage time of each security mode in a predetermined period using the setting history of the security mode. This usage time refers to the time when the security mode was set.

[0037] The transmission means 413 transmits the integrated information indicating the total usage time of each security mode calculated by the calculation means 412 and the security mode information acquired by the acquisition means 411 to the terminal device 600. The integrated information includes information indicating the predetermined period and the total usage time of each security mode. The security mode information includes information indicating the type of the set security mode and the setting date and time of the security mode.

[0038] FIG. 4 is a diagram showing an example of the configuration of the terminal device 600. The terminal device 600 includes a control unit 601, a storage unit 602, a communication unit 603, an operation unit 604, and a display unit 605. Each unit of the terminal device 600 is connected via a bus. The control unit 601, the storage unit 602, the communication unit 603, the operation unit 604, and the display unit 605 are basically the same as the control unit 201, the storage unit 202, the communication unit 403 of the server device 400, the operation unit 204, and the display unit 205 of the controller 200, respectively. However, an application program for realizing the functions of the terminal device 600 is stored in the storage unit 602. The operation unit 604 includes, for example, a touch sensor that receives operations on the screen of the display unit 605 and operation buttons that receive various operations. The terminal device 600 is an example of the "computer" according to the present invention, and the application program stored in the storage unit 602 is an example of the "program" according to the present invention. The display unit 605 is an example of the "display means" according to the present invention.

[0039] The control unit 601 functions as an acquisition unit 611 and a display control unit 612. These functions are realized by the control unit 601 executing a program stored in the storage unit 602, causing the control unit 601 to perform calculations or control each unit of the terminal device 600.

[0040] The acquisition unit 611 acquires integrated information and security mode information from the server device 400.

[0041] The display control unit 612 uses the integrated information and the security mode information acquired by the acquisition unit 611 to display on the display unit 605 information corresponding to the total usage time of each security mode and the time zone in which each security mode was set.

[0042] Operation FIG. 5 is a sequence chart showing an example of an operation for providing information indicating the usage status of the security mode. In one example, this operation is started at a predetermined time interval. Note that the terminal device 600 may be the terminal device 600 used by the caregiver, or the terminal device 600 used by the subject, or both the terminal device 600 used by the caregiver and the terminal device 600 used by the subject.

[0043] In step S11, the setting means 212 of the controller 200 determines whether or not the security mode has been changed. For example, if an operation to change the security mode is not performed by the subject, the determination in step S11 becomes NO. In this case, the process ends. On the other hand, if an operation to change the security mode is performed by the subject and the setting means 212 changes the security mode in response to this operation, the determination in step S11 becomes YES. In this case, the process proceeds to step S12.

[0044] In step S12, the transmission means 213 of the controller 200 transmits the security mode information to the server device 400. For example, when the security mode is changed from the manned security mode to the unmanned security mode at 10:00 on December 1, 20XX, the security mode information includes information indicating the type of "unmanned security mode" and the set date and time of "December 1, 20XX, 10:00". The acquisition means 411 of the server device 400 receives the security mode information from the controller 200.

[0045] In step S13, the acquisition means 411 of the server device 400 stores the received security mode information in the storage unit 402. In this way, each time the security mode is changed, the security mode information received from the controller 200 is stored in the storage unit 402. A setting history of the security mode is configured by a plurality of pieces of security mode information stored in the storage unit 402.

[0046] In step S14, the calculation means 412 of the server device 400 performs an integration process of calculating the total usage time for a predetermined period for each security mode using the setting history of the security mode stored in the storage unit 402. Here, it is assumed that the predetermined period is one day. The setting history of the security mode stored in the storage unit 402 includes the setting date and time of each security mode. From the setting date and time of each security mode, the time zone during which each security mode was set can be obtained. For example, if the manned security mode was set from 0:00 to 9:00 and from 18:00 to 24:00 on December 1, 20XX, the total usage time of the manned security mode on this day is 9 hours from 0:00 to 9:00 plus 6 hours from 18:00 to 24:00, which is 15 hours. Also, if the unmanned security mode was set from 9:00 to 15:00 on December 1, 20XX, the total usage time of the unmanned security mode on this day is 6 hours from 9:00 to 15:00. Furthermore, if the release mode was set from 15:00 to 18:00 on December 1, 20XX, the total usage time of the release mode on this day is 3 hours from 15:00 to 18:00.

[0047] In step S15, the transmission means 413 of the server device 400 transmits integration information indicating the result of the integration process in step S14 and security mode information for a predetermined period stored in the storage unit 402 to the terminal device 600. The integration information includes information indicating the predetermined period and the total usage time for each security mode within that predetermined period. The security mode information for the predetermined period includes information indicating the type of security mode set during the predetermined period and the setting date and time of that security mode. The acquisition means 611 of the terminal device 600 receives the integration information and the security mode information from the server device 400.

[0048] In step S16, the display control means 612 of the terminal device 600 uses the received integration information and security mode information to display on the display unit 605 information corresponding to the total usage time for each security mode during the predetermined period and the time zone during which each security mode was set.

[0049] FIG. 6 is a diagram showing an example of a screen 650 displayed on the display unit 605. The screen 650 includes a screen 650A on a daily basis and a screen 650B on a weekly basis. These screens 650A and 650B are switched according to an operation using the operation unit 604. For example, in response to an operation of switching the switch 690 included in the screen 650A, the screen is switched from the screen 650A to the screen 650B. Similarly, in response to an operation of switching the switch 690 included in the screen 650B, the screen is switched from the screen 650B to the screen 650A.

[0050] The screen 650A includes a graph 651 which is a figure representing the total usage time for each security mode. The graph 651 is a 100% stacked bar graph representing the ratio of the total usage time of each security mode in a day. The vertical axis of the graph 651 indicates the time of a day. The bars 652, 653, and 654 represent the ratio of the total usage time of the manned security mode, the ratio of the total usage time of the unmanned security mode, and the ratio of the total usage time of the release mode, respectively. The bars 652 to 654 are displayed separately by making the color, shade, or pattern different. The bars 652, 653, and 654 are an example of the "element" according to the present invention. In the graph 651, the bar 653 is stacked first, and the bars 652 and 654 are stacked in order on the bar 653. That is, the bar 653 representing the total usage time of the unmanned security mode is arranged first. That is, from the origin of the graph 651, the bars 653 and 652 representing the total usage time are displayed in the order of the unmanned security mode and the manned security mode.

[0051] Here, it is assumed that the target day of the screen 650A is December 1, 20XX. For example, when the total usage time of the manned security mode on December 1, 20XX is 15 hours, the bar 652 has a length corresponding to the ratio of this total usage time in a day. Also, when the total usage time of the unmanned security mode on December 1, 20XX is 6 hours, the bar 653 has a length corresponding to the ratio of this total usage time in a day. Further, when the total usage time of the release mode on December 1, 20XX is 3 hours, the bar 654 has a length corresponding to the ratio of this total usage time in a day.

[0052] By looking at Graph 651, the caregiver or the person being monitored can understand the percentage of the total usage time for each security mode occupied in a day. Also, by looking at Bars 652 and 653 together, the caregiver or the person being monitored can understand the total usage time of the alert mode occupied in a day. For example, if the percentage of the total usage time of the release mode is high, it means that the security mode is not being used properly. On the other hand, if the percentage of the total usage time of the release mode is low and the percentage of the total usage time of the alert mode is high, it means that the security mode is being used properly. From Graph 651, the caregiver or the person being monitored can visually recognize the percentage of the total usage time of the security mode set in a day for each security mode, and can immediately confirm whether the alert mode was set and the monitoring service was utilized.

[0053] Also, the screen 650A includes a donut-shaped chart 655 representing the time zones in which each security mode was set. Chart 655 is a type of graph. In the example described above, from 0:00 to 9:00 on December 1, 20XX, the manned security mode was set, from 9:00 to 15:00 the unmanned security mode was set, from 15:00 to 18:00 the release mode was set, and from 18:00 to 24:00 the manned security mode was set. In this case, along the time axis of the circumference, elements 656 representing the manned security mode are displayed in the time zones from 0:00 to 9:00 and from 18:00 to 24:00, element 657 representing the unmanned security mode is displayed in the time zone from 9:00 to 15:00, and element 658 representing the release mode is displayed in the time zone from 15:00 to 18:00. That is, these elements 656 to 658 are displayed in chronological order. Elements 656 to 658 are displayed separately by differentiating colors, shades of colors, or patterns.

[0054] By looking at the chart 655, the person watching over or the subject can see the time periods during which each security mode was set. For example, after checking the total usage time of the deactivation mode in the graph 651, by looking at the chart 655, the person watching over or the subject can see at what time of day the deactivation mode was actually set. Also, for example, if the time period during which the deactivation mode was set is a time period during which the subject moves around inside and outside the house, this means that the security mode is being used appropriately. On the other hand, if the time period during which the deactivation mode was set is a time period during which the subject stays in the same place and does not move much, such as when the subject is sleeping, this means that the security mode is not being used appropriately.

[0055] Screen 650B displays graphs 651 for each day of the week arranged horizontally. Screen 650B may also display a reference line 659 indicating a reference value of usage time of the security modes, including the manned security mode and the unmanned security mode. The total usage time of the security modes is obtained by adding the total usage time of the manned security mode and the total usage time of the unmanned security mode. This reference value is a guide to whether or not the security mode is being used appropriately. For example, if the total usage time of the security mode is equal to or greater than the reference value, it means that the security mode is being used appropriately. The reference value may be set in advance, or may be changed daily depending on the type of security mode set.

[0056] For example, if the security modes set on a certain day do not include the manned alert mode, a first reference value determined in advance is used as the reference value for that day. On the other hand, if the security modes set on a certain day include the manned alert mode, a second reference value smaller than the first reference value is used as the reference value for that day. This is because, when the manned alert mode is set, the subject is considered to have a high level of crime prevention awareness, and therefore, even if the total usage time of the alert mode is shorter than when the manned alert mode is not set, the security mode is considered to be used appropriately.

[0057] In the above-described step S15, the integrated information and the security mode information may be transmitted in a push type from the server device 400, or may be transmitted in a pull type in response to a request from the terminal device 600. In one example, when an application program for providing a monitoring service function is activated in the terminal device 600, a request for acquiring the integrated information and the security mode information is sent from the terminal device 600 to the server device 400, and in response to this acquisition request, these pieces of information are transmitted from the server device 400 to the terminal device 600.

[0058] Also, when a real-time information acquisition request is made from the terminal device 600 in the case of being transmitted in a pull type in response to a request from the terminal device 600, the period from the start time to the current time of a predetermined period becomes the predetermined period. For example, when a real-time information acquisition request is made at 15:00 on December 1, 20XX, the total usage time of each security mode from 0:00 to 15:00 on December 1, 20XX is calculated and transmitted from the server device 400 to the terminal device 600. In this case, the graph 651 for December 1, 20XX represents the ratio of the total usage time of each security mode in the time from 0:00 to 15:00. Also, the chart 655 for December 1, 20XX represents the time zones in which each security mode was set in the period from 0:00 to 15:00. For time zones after 15:00, no elements representing the security mode are displayed.

[0059] According to the above-described embodiment, since the graph 651 representing the total usage time of each security mode is displayed, it is possible to visually and easily review whether the plurality of security modes are being used appropriately. Further, in addition to the graph 651, a chart 655 representing the time zone in which each security mode was set is displayed, so that by looking at these together, it is possible to more detailedly confirm whether the plurality of security modes are being used appropriately. Furthermore, by displaying the graph 651 representing the ratio of the total usage time of each security mode in a day, the ratio of the total usage time of each security mode in a day can be easily visually recognized. Furthermore, in the graph 651, since the bar 653 representing the total usage time of the unmanned security mode is arranged first, it is possible to easily compare the ratio of the total usage time of the unmanned security mode on each day of the week, particularly in the screen 650B on a weekly basis.

[0060] Modification Example The present invention is not limited to the above-described embodiment. The above-described embodiment may be modified and implemented as follows. At this time, two or more of the following modification examples may be used in combination.

[0061] Modification Example 1 In the above-described embodiment, the graph representing the total usage time of each security mode is not limited to the graph 651. The graph representing the total usage time of each security mode may be any type of graph as long as it can show the total usage time of each security mode or the ratio of the usage time of each security mode in a day.

[0062] FIG. 7 is a diagram showing an example of a graph 660 representing the total usage time of each security mode according to this modification. The graph 660 is a pie chart representing the ratio of the total usage time of each security mode in a day. The circumference of the graph 660 indicates the time of a day. Elements 661, 662, and 663 represent the ratio of the total usage time of the manned security mode, the ratio of the total usage time of the unmanned security mode, and the ratio of the total usage time of the release mode, respectively, and have sizes corresponding to the ratios of the total usage time of each. The elements 661 to 663 are separately displayed by differentiating colors, shades of colors, or patterns. In the graph 660, the elements 662, 661, and 663 are arranged in order clockwise starting from 0. That is, the element 662 representing the ratio of the total usage time of the unmanned security mode is arranged first when viewed from the origin. By looking at the graph 660, the caregiver or the subject can know the ratio of the total usage time of each security mode in a day. Also, the graph 660 may be displayed in place of the graph 651 in the screen 650B on a weekly basis as well.

[0063] FIG. 8 is a diagram showing an example of a graph 670 representing the usage time of each security mode according to this modification. The graph 670 is a grouped bar graph. The vertical axis (not shown) of the grouped bar graph indicates time. The bars 671, 672, and 673 represent the total usage time of the manned security mode, the total usage time of the unmanned security mode, and the total usage time of the release mode, respectively, and have lengths corresponding to the total usage time of each. The bars 671 to 673 are separately displayed by differentiating colors, shades of colors, or patterns. In the graph 670, the bars 672, 671, and 673 are arranged in order from the left. That is, the bar 672 representing the total usage time of the unmanned security mode is arranged first when viewed from the origin. By looking at the graph 670, the caregiver or the subject can know the total usage time of each security mode.

[0064] Modification 2 In the above-described embodiment, the graph 651 and the chart 655 may not be included in one screen. For example, the graph 651 and the chart 655 may be included in different screens, and each screen may be displayed in response to an operation to switch between the screens. In addition, in the graph 651 shown in FIG. 6, the bar 653 representing the unmanned alert mode may not necessarily be arranged first when viewed from the origin. For example, the bar 652 representing the attended alert mode or the bar 654 representing the released mode may be arranged first when viewed from the origin. Similarly, in the graph 660 shown in FIG. 7, the element 661 or 663 may be arranged first when viewed from the origin, and in the graph 670 shown in FIG. 8, the bar 671 or 673 may be arranged first when viewed from the origin.

[0065] Variation 3 In the above-described embodiment, information according to the detection result of the sensor 100 may be added to at least one of the graph 651 and the chart 655. In one example, the detection result or attribute information of the sensor 100 during the time period when the deactivation mode was set may be added to the graph 651 and the chart 655. In this example, the server device 400 extracts detection information included in the time period when the deactivation mode was set for the detection time from the detection information received from the sensor 100. The detection information extracted by the server device 400 is transmitted to the terminal device 600 and displayed together with the total usage time of each security mode and the time period when each security mode was set.

[0066] For example, if a window sensor detects an open window during a time period when the release mode was set, additional information indicating that the window is open may be added to bar 654 representing the total percentage of the usage time of the release mode in graph 651 shown in Fig. 6. Also, additional information indicating that the window is open may be added to element 658 representing the release mode in chart 655 shown in Fig. 6. By looking at this additional information, the watcher or the subject can tell whether the setting of the release mode was appropriate or not.

[0067] In another example, time periods with low activity levels of the subject among the time periods when the release mode was set may be displayed on graph 651 and chart 655 as time periods for improvement candidates. In this example, the server device 400 determines the activity level of the subject in a predetermined period for each time period using the detection information received from the sensor 100. For example, the server device 400 determines a larger activity level as the number of times the activity of the subject is detected by the sensor 100 is greater. Subsequently, the server device 400 identifies, as a time period for an improvement candidate, a time period in which the activity level of the subject is equal to or less than a predetermined activity level among the time periods when the release mode was set. For example, when the release mode was set from 15:00 to 18:00 on December 1, 20XX, if the activity level of the subject in the time period from 17:00 to 18:00 among this time period is equal to or less than the predetermined activity level, the time period from 17:00 to 18:00 is identified as a time period for an improvement candidate. Improvement information indicating the time period for an improvement candidate identified by the server device 400 is transmitted to the terminal device 600 and is displayed together with the total usage time of each security mode and the time periods when each security mode was set.

[0068] For example, in graph 651 shown in FIG. 6, a portion corresponding to the length of the time period for an improvement candidate may be highlighted among bars 654 representing the ratio of the total usage time of the release mode. Also, in chart 655 shown in FIG. 6, a portion corresponding to the time period for an improvement candidate may be highlighted among elements 658 representing the release mode. This highlighting is realized, for example, by varying colors, color densities, or patterns. By looking at this highlighting, the caregiver or the subject can understand that for a part of the time periods when the release mode was set in the past, another security mode, for example, the manned security mode, should have been set.

[0069] Also, the reference value of the usage time in the warning mode may be the time obtained by adding the length of the time period of the improvement candidate to the total actual usage time in the warning mode. For example, if the total actual usage time in the manned warning mode on December 1, 20XX is 15 hours, the total actual usage time in the unmanned warning mode is 6 hours, and the length of the time period of the improvement candidate is 1 hour, the reference value is 22 hours, which is the total of these times. In this case, on the graph 651 for December 1, 20XX on the screen 650B shown in FIG. 6, a reference line 659 indicating the reference value of 22 hours is displayed. By looking at this reference line 659, the caregiver or the subject can know the total time when the warning mode should have been set.

[0070] Note that the time period of the improvement candidate may be specified using AI (Artificial Intelligence). For example, the server device 400 generates a machine learning model in advance by machine learning the detection information of the sensor 100 and the appropriate security mode. The server device 400 inputs the detection information of the sensor 100 during a predetermined period into this machine learning model to determine the appropriate security mode for each time period during the predetermined period. Then, the server device 400 may compare the appropriate security mode determined for each time period with the actually set security mode, and specify the time period in which these security modes are different as the time period of the improvement candidate.

[0071] Alternatively, an appropriate security mode may be predetermined for each time period, and the server device 400 may set the time period in which the actually set security mode is different from the predetermined security mode as the time period of the improvement candidate. For example, a manned warning mode may be predetermined as an appropriate security mode for the late-night time period. In this case, if a security mode other than the manned warning mode is set in the late-night time period, the portion where the security mode other than the manned warning mode is set is specified as the time period of the improvement candidate.

[0072] According to this modification example, it is possible to more detailedly check whether a plurality of security modes are being appropriately used.

[0073] Modification Example 4 In the above-described embodiments, the reference value of the usage time of the warning mode may be changed according to the usage time of the manned warning mode. For example, the longer the usage time of the manned warning mode, the smaller the reference value may be.

[0074] Modification Example 5 In the above-described embodiments, when the total usage time of the warning mode has not reached the reference value, at least one of the total usage time of the release mode and the time period during which the release mode was set may be highlighted. For example, when the total usage time of the warning mode has not reached the reference value, in the graph 651 shown in FIG. 6, the bar 654 representing the ratio of the total usage time of the release mode may be highlighted. Also, in the chart 655 shown in FIG. 6, the element 658 representing the release mode may be highlighted. This highlighting is realized, for example, by varying colors, color densities, or patterns. Note that when the total usage time of the warning mode has reached the reference value, no highlighting is performed. According to this display, it is possible to notify that there is room for improvement in the setting of the release mode when the total usage time of the warning mode has not reached the reference value.

[0075] Modification Example 6 In the above-described embodiments, the value calculated using the setting history of the security mode in the server device 400 is not limited to the total usage time of each security mode. For example, using the setting history of the security mode, statistical quantities other than the total, such as the average value, maximum value, and minimum value of the usage time of each security mode, may be calculated. In this case, the statistical quantity calculated in the server device 400 is transmitted to the terminal device 600 and displayed in the terminal device 600.

[0076] Modification Example 7 In the above-described embodiments, the total usage time for each security mode and the time zones in which each security mode was set may be displayed without using a graph. For example, numerical values of the ratios of the total usage time for each security mode may be displayed. Also, for the time zones in which each security mode was set, a table may be used with the horizontal axis representing each time zone of the day and the vertical axis representing the security modes, and the security modes set for each time zone may be displayed in chronological order.

[0077] Modification Example 8 In the above-described embodiments, the server device 400 may generate web screens corresponding to the screens 650A and 650B and provide them to the terminal device 600.

[0078] Modification Example 9 In the above-described embodiments, the functions of one device may be distributed among a plurality of devices, or one device may collectively have the functions of a plurality of devices. For example, the controller 200 had both the function of monitoring for intrusion into the monitored area and the function of watching over the target person. However, instead of the controller 200, a first controller having the function of monitoring for intrusion into the monitored area and a second controller having the function of watching over the target person may be used.

[0079] Modification Example 10 In the above-described embodiments, the main body of the functions of the monitoring system 10 is an example and is not limited to this example. The functions of the server device 400 may be possessed by the controller 200 or the terminal device 600. That is, the processing performed by the server device 400 may be performed by the controller 200 or the terminal device 600. In one example, at least a part of the acquisition means 411, calculation means 412, and transmission means 413 of the server device 400 may be possessed by the controller 200 or the terminal device 600.

[0080] Modification Example 11 In the above-described embodiments, the operation of the monitoring system 10 is not limited to the above-described examples. The processing procedures of the monitoring system 10 may be rearranged as long as there is no contradiction. Also, some of the processing procedures of the monitoring system 10 may be omitted.

[0081] Modification Example 12 Another aspect of the present invention may provide a method having steps of processing performed in at least any one of the monitoring system 10, the sensor 100, the controller 200, the setting unit 300, the server device 400, and the terminal device 600. Still another aspect of the present invention may provide a program executed in the sensor 100, the controller 200, the setting unit 300, the server device 400, or the terminal device 600. This program may be provided by being stored in a computer-readable recording medium, or may be provided by being downloaded via the Internet or the like.
