[0004] In the technology described in Patent Document 1, etc., sensor information is sent to a pre-registered mobile terminal. However, when the subject goes out or goes to bed, the subject's activity is not detected by the sensor, so the person watching over the subject cannot know the subject's situation by looking at only the sensor information.

[0005] An object of the present invention is to enable a subject's situation to be recognized in more detail even when the subject is not very active. [Means for solving the problem]

[0006] One aspect of the present invention is a monitoring system that monitors for intrusions into a monitored area where a subject is located based on a security mode and provides information indicating the subject's activity status, comprising a setting means for setting the security mode, a detection means provided in the monitored area for detecting movement of the subject, a measurement means for measuring the subject's activity level in accordance with the detection results of the detection means, and a display means for displaying in chronological order the activity level and the security mode for a predetermined period of time, corresponding them to each time zone based on the measured activity level and the setting history of the security mode.

[0007] The display means may display a graphic representing the amount of activity for each time period and the security mode on the same time axis.

[0008] The display means may color each of the time periods in accordance with a combination of the magnitude of the activity level and the type of security mode, and display the activity level and the security mode as a single band-shaped graphic along the time axis.

[0009] The security mode is a plurality of security modes including at least an alert mode in which the monitored area is monitored and a deactivated mode in which the monitored area is not monitored, and the display means may not display the deactivated mode but may display the time period during which the alert mode was set.

[0010] The alert mode may include an unmanned alert mode that monitors the entire monitored area and a manned alert mode that monitors a portion of the monitored area, and the display means may display the time period during which the unmanned alert mode was set without displaying the manned alert mode.

[0011] The detection means may be a plurality of detection means that detect the movement of the subject, and the display means may display information regarding the detection means that detected the movement that is a factor in the amount of activity during the selected time period among a plurality of time periods in response to an operation of selecting any one of a plurality of time periods.

[0012] The detection means may be a plurality of detection means that detect the movement of the subject, and the measurement means may measure the amount of activity based on at least one of the number of times that at least any one of the plurality of detection means detects the movement, the type of the detection means, and the installation location of the detection means.

[0013] Another aspect of the present invention provides a server device that communicates with a terminal device carried by a person watching over a subject, and a security device that monitors for intrusions into a monitored area in which the subject is located based on a security mode and provides information indicating the subject's activity status, characterized in that the server device comprises an acquisition means for acquiring security mode information indicating the security mode set from the security device and the detection results of a detection means for detecting the movement of the subject, a measurement means for measuring the subject's activity level in accordance with the detection results, and a transmission means for transmitting time series data of the activity level and the security mode information for a specified period of time to the terminal device so that the activity level and the set security mode for the specified period of time are displayed in chronological order in correspondence with each other for each time zone.

[0014] Yet another aspect of the present invention provides a terminal device included in a monitoring system that monitors for intrusions into a monitored area in which a subject is located based on a security mode and provides information indicating the subject's activity status, characterized in that the terminal device comprises: an acquisition means for acquiring security mode information indicating the set security mode and the subject's activity level measured in accordance with the detection results of a detection means for detecting the movement of the subject; and a display means for displaying in chronological order the activity level and the security mode for a predetermined period of time, based on the security mode setting history and the activity level indicated by the security mode information, in association with each other for each time period.

[0015] Yet another aspect of the present invention provides a program for causing a computer included in a monitoring system that monitors for intrusions into a monitored area in which a subject is located based on a security mode and provides information indicating the subject's activity status to execute the steps of acquiring security mode information indicating the set security mode and the subject's activity level measured in accordance with the detection results of a detection means that detects the subject's movement, and displaying the activity level and the security mode in chronological order for a predetermined period of time based on the security mode setting history and the activity level indicated by the security mode information.

[0018] composition FIG. 1 is a diagram showing an example of the configuration of a monitoring system 10 according to an embodiment. The monitoring system 10 provides a monitoring service that monitors abnormalities such as intrusions into a monitoring target area where a subject is located, and a monitoring service that monitors the condition of a subject such as an elderly person. In this monitoring service, information indicating the activity status measured in the subject's daily life without placing a burden on the subject is provided to a watcher such as a family member living apart from the subject. This allows the watcher to recognize the subject's condition and to watch over the subject in a relaxed manner.

[0019] The monitoring system 10 includes a plurality of sensors 100, a controller 200, a setting unit 300, a server device 400, and terminal devices 500 and 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 subject, 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 that provides monitoring services and monitoring services. The terminal device 500 is carried and used by the subject. The terminal device 600 is carried and used by a watcher. The controller 200, the server device 400, the terminal device 500, and the terminal device 600 are connected via a communication network 12 including the Internet and a mobile communication network.

[0020] The multiple sensors 100 detect the activity (movement) of a subject in the monitored area and output detection information indicating the detection result. The multiple sensors 100 are an example of the "detection means" according to the present invention. At least a part of the multiple sensors 100 detects an intruder into the monitored area and outputs detection information. When the monitored area is a residence, the multiple sensors 100 include a sensor 100 installed inside the residence (hereinafter also referred to as the "indoor sensor 100") and a sensor 100 installed outside the residence (hereinafter also referred to as the "outdoor sensor 100"). The indoor sensor 100 is installed, for example, at an opening such as a front door or a window, a traffic line such as a passageway in the residence, or a living room. The outdoor sensor 100 is installed, for example, in a garden or a gate. In one example, the multiple sensors 100 include a window / door sensor, a human sensor, a Time Of Flight (TOF) sensor, an ultrasonic (millimeter wave, microwave) sensor, and a lighting / home appliance / infrastructure operation detection sensor.

[0021] Window / door sensors are installed in openings such as entrance doors, windows, and gates to detect the opening of doors and windows, and are used for both monitoring and intrusion monitoring. Examples of window / door sensors include sensors that detect the opening of doors by detecting changes in magnetic fields, and sensors that detect the opening of doors by turning on / off a tamper switch. Human presence sensors, also called spatial sensors, are installed in traffic lines and rooms to detect the presence of people, and are used for both monitoring and intrusion monitoring. Examples of human presence sensors include sensors that detect the presence of people by fluctuations in heat rays emitted by the human body, sensors that detect the presence of people by sound waves or high frequencies, sensors that detect the presence of people by processing images captured by surveillance cameras, and sensors that detect the presence of people by blocking the incoming light from a light projector. Time-of-Flight (TOF) sensors and ultrasonic sensors are installed in traffic lines and rooms to detect the posture of the target person, in addition to their use as human presence sensors. The lighting / home appliance operation detection sensor is a sensor that detects an operation on a home appliance, and is used for monitoring purposes. The lighting / home appliance operation detection sensor may be provided in a home appliance and detect an operation performed using an operation button on the home appliance. Alternatively, the lighting / home appliance / infrastructure operation detection sensor may be provided in a location where an operation signal transmitted from a remote controller to the home appliance can be received, and may detect an operation on the home appliance based on this operation signal. Examples of home appliances include television receivers, lighting equipment, air conditioners, heaters, electric fans, electric kettles, and radios. For example, when it is detected that a television has been operated, it is possible to detect the activity (movement) of a subject who turned on the television in the living room from the location where the television is installed (such as the living room) and the time of the operation. Furthermore, as a sensor for monitoring purposes, a sensor that detects the usage of lifelines such as water, gas, and electricity, or an environmental sensor (such as a sensor that detects illuminance and carbon dioxide concentration in the air) may be used.

[0022] The controller 200 monitors for intrusion into a monitored area where a target person is located using the sensor 100. For example, when an intruder is detected by the sensor 100, the controller 200 notifies the server device 400 that the intruder has intruded into the monitored area. The controller 200 is an example of a "security device" according to the present invention. The controller 200 has three security modes: an unmanned security mode, an attended security mode, and a released mode.

[0023] The unmanned alert mode is a security mode that monitors the entire monitored area. The unmanned alert mode is used when the subject goes out and the monitored area is unmanned. In the unmanned alert mode, when detection information is output from any of the sensors for intrusion monitoring among the multiple sensors 100, an abnormality signal is transmitted from the controller 200 to the server device 400. Note that, when the unmanned alert mode is set, it is preferable that the sensor 100 monitoring the subject's exit route starts detecting an intruder after a predetermined time has elapsed since the unmanned alert mode was set, so as not to erroneously detect the subject who goes out as an intruder.

[0024] 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 by a sensor for intrusion monitoring to detect an intrusion from the outside into the monitored area. Alternatively, an area (such as the second floor) designated by the subject's operation among 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 installed in the outer perimeter area or the designated area, 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.

[0025] 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.

[0026] Since these security modes have different uses, the location of the target can be determined from the security mode setting. For example, if the unmanned security mode is set, it can be determined that the target is out. On the other hand, if the manned security mode is set, it can be determined that the target is in a part of the monitored area that is not being monitored.

[0027] 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.

[0028] When the server device 400 receives an abnormality signal from the controller 200, it outputs information on the area to be monitored and the subject, thereby prompting the monitoring sensor controller to check on the subject and the security guard rushing to the area to be monitored to deal with the situation. The server device 400 also measures the amount of activity of the subject according to the detection result of the sensor 100, and provides the terminal device 500 with information indicating the amount of activity and the security mode set in the controller 200. This information is used as information indicating the activity status of the subject.

[0029] The terminal device 500 is used by a subject to view various types of information related to a monitoring service or a watching service. Examples of the terminal device 500 include a smartphone, a mobile phone, a personal computer, a tablet terminal, and a wearable terminal.

[0030] The terminal device 600 is used by the watcher to view various information related to the monitoring service and the watch service, such as information showing the activity status of the target person. Examples of the terminal device 600 include a smartphone, a mobile phone, a personal computer, a tablet terminal, and a wearable terminal.

[0031] 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 sound unit 206. The various units of the controller 200 are connected to each other via a bus.

[0032] The control unit 201 is a processor that controls each part of the device 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 implementing the functions of the device. The data stored in the storage unit 202 includes information indicating the currently set security mode, an authentication code required for setting the security mode, and detection information of the sensor 100. For example, the storage unit 202 includes at least one of a ROM (Read Only Memory), a RAM (Random Access Memory), a HDD (Hard Disk Drive), and an SSD (Solid State Drive). The communication unit 203 is a communication interface for connecting the device to the communication networks 11 and 12. The communication unit 203 is used to communicate with other devices connected via the communication networks 11 or 12. The detection information of the sensor 100 may not be stored in the storage unit 202, but may be transmitted to the server device 400 every time the sensor 100 detects the sensor.

[0033] The operation unit 204 accepts various operations for the device itself. The operations accepted by the operation unit 204 include an operation for setting a security mode and an operation for reading an authentication code from an authentication medium. For example, the operation unit 204 includes a touch sensor for accepting an operation on the screen of the display unit 205, an operation button for accepting a setting of the security mode, and a reading device for reading an authentication code from an authentication medium such as an IC card carried by the subject. The display unit 205 displays various information. The information displayed by the display unit 205 includes information indicating the currently set security mode, the state of the sensor 100, and the installation location of the sensor 100. For example, the display unit 205 includes a liquid crystal display. The display unit 205 may also be configured as a touch panel in combination with a touch sensor. The sound unit 206 outputs various sounds such as a sound notifying the occurrence of an abnormality and a message voice. For example, the sound unit 206 includes a speaker.

[0034] The control unit 201 functions as an acquiring unit 211, a setting unit 212, and a transmitting unit 213. These functions are realized by the control unit 201 executing a program stored in the storage unit 202, and the control unit 201 performing calculations or controlling each unit of the controller 200.

[0035] The acquiring means 211 acquires the detection information output from the sensor 100. Furthermore, when an operation to set the security mode is performed using the setting unit 300, the acquiring means 211 acquires operation information indicating this operation.

[0036] The setting means 212 sets one of a plurality of security modes in response to an operation by a target person. When an operation to set a security mode is performed using the operation unit 204, the setting means 212 sets a security mode in response to this operation, and when an operation to set a security mode is performed using the setting unit 300, the setting means 212 sets a security mode in response to the operation information acquired by the acquisition means 211.

[0037] The transmitting means 213 transmits to the server device 400 the detection information of the sensor 100 acquired by the acquiring means 211 and security mode information indicating the security mode set by the setting means 212. The detection information includes information indicating the type of sensor 100, the date and time when the sensor 100 detected the detection target, and the installation location of the sensor 100. The security mode information includes information indicating the type of security mode that has been set and the date and time when that security mode was set.

[0038] 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. The units of the server device 400 are 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 device itself to the communication network 12, and is used to communicate with other devices connected via the communication network 12.

[0039] The control unit 401 functions as an acquisition unit 411, a measurement unit 412, and a transmission unit 413. These functions are realized by the control unit 401 executing a program stored in the storage unit 402, and the control unit 401 performing calculations or controlling each unit of the server device 400.

[0040] The acquisition means 411 acquires the detection information of the sensor 100 and the security mode information from the controller 200 .

[0041] The measuring means 412 measures the activity amount of the subject for each time period according to the detection information acquired by the acquiring means 411. The measurement here also includes determining the degree of the activity amount of the subject. In one example, the measuring means 412 measures a larger activity amount based on the detection information stored in the storage unit 402, the more times the sensor 100 detects the subject's activity. In other words, the measuring means 412 measures a smaller activity amount based on the detection information stored in the storage unit 402, the less times the sensor 100 detects the subject's activity. Note that the measuring means 412 determines that there is no activity amount when the sensor 100 does not detect the subject's activity.

[0042] The transmitting means 413 transmits activity amount information indicating the amount of activity measured by the measuring means 412 and security mode information acquired by the acquiring means 411 to the terminal device 600. The activity amount information includes information indicating the time period when the activity amount was measured and the amount of activity (time series data of the activity amount). The security mode information includes information indicating the type of security mode that has been set and the date and time when the security mode was set (time series data of the security mode).

[0043] 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. The units of the terminal device 600 are 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, the operation unit 204, and the display unit 205 of the controller 200, respectively. However, the storage unit 602 stores an application program for realizing the functions of the terminal device 600. The terminal device 600 is an example of a "computer" according to the present invention, and the application program is an example of a "program" according to the present invention. The display unit 605 is an example of a "display means" according to the present invention. The terminal device 500 may have a configuration similar to that of the terminal device 600.

[0044] 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, and the control unit 601 performing calculations or controlling each unit of the terminal device 600.

[0045] The acquisition means 611 acquires the activity amount information and the security mode information from the server device 400 .

[0046] The display control means 612 displays on the display unit 605 the subject's activity level for each time period during a specified period and the set security mode based on the activity level information acquired by the acquisition means 611 and the security mode setting history indicated by the security mode information acquired by the acquisition means 611.

[0047] operation 5 is a sequence chart showing an example of an operation related to a monitoring service. This operation is started at a predetermined time interval.

[0048] In step S11, the setting means 212 of the controller 200 judges whether the security mode has been changed. For example, if the subject has not performed an operation to change the security mode, the judgment in step S11 is NO. In this case, the process skips steps S12 and S13 described below and proceeds to step S14. On the other hand, if the subject has performed an operation to change the security mode and the setting means 212 has changed the security mode in response to this operation, the judgment in step S11 is YES. In this case, the process proceeds to step S12.

[0049] In step S12, the transmitting means 213 of the controller 200 transmits the security mode information to the server device 400. For example, if the manned security mode is changed to the unmanned security mode at 10:00 on Dec. 1, 20XX, the security mode information includes information indicating the type "unmanned security mode" and the set date and time "10:00 on Dec. 1, 20XX." The acquiring means 411 of the server device 400 receives the security mode information from the controller 200.

[0050] 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 manner, every time the security mode is changed, the security mode information received from the controller 200 is stored in the storage unit 402, whereby the security mode setting history of the controller 200 is stored in the storage unit 402.

[0051] In step S14, the acquisition means 411 of the controller 200 judges whether or not the subject's activity has been detected by the sensor 100. For example, if no detection information is output from any of the multiple sensors 100, the judgment in step S14 is NO. In this case, the operation ends without performing the subsequent processing. On the other hand, if detection information is output from at least one of the multiple sensors 100 and the acquisition means 211 acquires the detection information from the sensor 100, the judgment in step S14 is YES. In this case, the process proceeds to step S15.

[0052] In step S15, the transmitting means 213 of the controller 200 transmits the detection information acquired from the sensor 100 to the server device 400. For example, if a door sensor installed on the front door detects the opening of the front door at 14:00 on Dec. 1, 20XX, and the detection information is acquired from the sensor 100, the detection information includes information indicating the type "window / door sensor", the detection date and time "14:00 on Dec. 1, 20XX", and the installation location "front door". The acquiring means 411 of the server device 400 receives the detection information from the controller 200.

[0053] In step S16, the acquisition means 411 of the server device 400 stores the received detection information in the storage unit 402. In this manner, every time the activity of the subject is detected, the detection information received from the controller 200 is stored in the storage unit 402, whereby the storage unit 402 stores a detection history of the activity of the subject.

[0054] In step S17, the measuring means 412 of the server device 400 measures the subject's activity amount for each time period using the detection information stored in the storage unit 402. Specifically, the measuring means 412 extracts, for each time period, detection information whose detection date and time is included in that time period from the storage unit 402. Next, the measuring means 412 counts the number of times that the subject's activity is detected by the sensor 100 during that time period (hereinafter referred to as the "detection count") using the extracted detection information. Then, the measuring means 412 measures the subject's activity amount by comparing the counted detection count with a preset threshold value.

[0055] The measuring means 412 measures the amount of activity as "large" when the number of detections is equal to or greater than the threshold for "large" activity. The measuring means 412 measures the amount of activity as "medium" when the number of detections is equal to or greater than the threshold for "medium" activity and less than the threshold for "large" activity. The measuring means 412 measures the amount of activity as "small" when the number of detections is equal to or greater than the threshold for "small" activity and less than the threshold for "medium" activity. The measuring means 412 measures the amount of activity as "none" when the number of detections is less than the threshold for "small" activity.

[0056] Here, a time period is a time period divided into 12 equal parts in a day, and each time period is two hours long. The threshold for a "high" activity level is 10 times, the threshold for a "medium" activity level is 4 times, and the threshold for a "low" activity level is 2 times. For example, if the window sensor detects three times, the human sensor detects one time, and the door sensor detects one time between 14:00 and 16:00 on December 1, 20XX, the total number of detections by these sensors is 5 times. Since this total number of detections is between 4 and 10 times, a "medium" activity level is measured.

[0057] In step S18, the transmitting means 413 of the server device 400 transmits the activity amount information indicating the amount of activity measured in step S17 and the security mode information stored in the storage unit 402 to the terminal device 600. At this time, the activity amount information and the security mode information are transmitted in association with each other for each time period. When multiple security modes are set in one time period, the security mode with the longest set time among those security modes may be used as the security mode set in that time period. In this case, only the security mode information indicating the security mode with the longest set time may be transmitted, and security mode information indicating the other security modes may not be transmitted. In addition, the activity amount information and the security mode information may be transmitted separately. For example, the security mode information is transmitted with information indicating the security mode set in one day regardless of the time period divided into 12 equal parts, and the activity amount information is transmitted with information on the activity amount in each of the time periods divided into 12 equal parts.

[0058] For example, if the amount of activity for the time period "10:00 to 14:00 on Dec. 1, 20XX" is "none" and the security mode set for this time period, i.e. the security mode whose set date and time is for this time period, is the "unmanned security mode," then activity amount information indicating the time period "10:00 to 14:00 on Dec. 1, 20XX" and the amount of activity "none" and security mode information indicating the "unmanned security mode" are transmitted in association with each other. The acquisition means 611 of the terminal device 600 receives the activity amount information and security mode information from the server device 400.

[0059] In step S19, the display control means 612 of the terminal device 600 displays the activity amount of the subject for each time period in a predetermined period (such as one day) and the set security mode on the display unit 605 based on the received activity amount information and the setting history of the activity mode indicated by the received security mode information. That is, time series data indicating the magnitude of the activity amount in the predetermined period and time series data of the set security mode in the predetermined period are displayed in association with each other for each time period.

[0060] 6 is a diagram showing an example of a screen 650 displayed on the display unit 605. The screen 650 includes a day-by-day screen 650A and a week-by-week screen 650B. These screens 650A and 650B can be switched in response to an operation using the operation unit 604.

[0061] The screen 650A includes a graph 651, which is a figure showing the subject's activity level for each time period in a day. The vertical axis of the graph 651 indicates the time from 0:00 to 24:00. The graph 651 displays a bar-shaped figure colored differently so that the amount of activity in each time period in a day can be distinguished. The bar 652 indicates the amount of activity by the shade of color. The highest first density indicates a "large" amount of activity. The second highest second density indicates a "medium" amount of activity. The third highest third density indicates a "small" amount of activity. Note that when the amount of activity is "no", the bar 652 is hidden. That is, a bar-shaped graph is displayed from 0:00 to 24:00, and the time periods with "no" activity are colored with no activity (hidden), and the time periods with an amount of activity are colored with activity (shading or diagonal line pattern).

[0062] Here, it is assumed that the target date of screen 650A is December 1, 20XX. For example, if the amount of activity from "10:00 to 14:00 on December 1, 20XX" is "none", the bar 652 is not displayed in the time slot of "10:00 a.m. to 14:00". If the amount of activity from "14:00 to 16:00 on December 1, 20XX" is "medium", the bar 652 having a second density is displayed in the time slot of "14:00 to 16:00". This display indicates that no activity of the subject was detected from 10:00 to 14:00 on December 1, 20XX, and that the subject was engaged in a medium amount of activity from 14:00 to 16:00.

[0063] Furthermore, on screen 650A, bars 653 representing security modes associated with each time period are superimposed on graph 651, which is a bar-shaped figure. That is, on graph 651, the security modes set for each time period are displayed in different colors in a distinguishable manner. Bars 653 representing security modes have the same shape as bars 652 representing the amount of activity, but are displayed in a distinguishable manner from bars 652. Bars 653 representing security modes are displayed on the time axis of graph 651, and therefore bars 652 constituting graph 651 and bars 653 representing the set security modes are displayed on the same time axis.

[0064] On screen 650A, only bar 653 representing the unmanned security mode among the multiple security modes is displayed, and bar 653 representing the attended security mode and bar 653 representing the canceled mode are not displayed. In other words, only the time period during which the unmanned security mode was set among the three security modes is displayed. In this example, bar 653 representing the unmanned security mode has a diagonal line pattern.

[0065] For example, if the unmanned alert mode is set from 10:00 to 14:00 on December 1, 20XX, a bar 653 with a diagonal line pattern is displayed during the time period from 10:00 to 14:00. This display indicates that the subject was out from 10:00 to 14:00 on December 1, 20XX. This allows the watcher to know that the subject was out during the time period when the subject's activity was not detected, and therefore eliminates the need to check whether the subject was out during this time period. In other words, the graph 651 displays a band-shaped figure along the time axis from 0:00 to 24:00, and in this figure, the time period with "no" activity is colored as "no" (not displayed), and the time period with activity and the time period with the unmanned alert mode set is colored as "present" (shading or diagonal line pattern). Note that the bar 653 representing modes other than the unmanned alert mode may be displayed on the graph 651, and for example, the security mode may be colored (red: unmanned alert mode, blue: attended alert mode, gray: released mode, etc.) and the activity may be colored as shading.

[0066] Screen 650B shows the subject's activity level for one week. Screen 650B displays graphs 651 showing the activity level for each day of the week arranged horizontally. Note that when displayed on screen 650B, graph 651 is reduced in the horizontal direction. Screen 650B may also display line 654 showing the current time on the time axis.

[0067] According to the above-described embodiment, if the unmanned alert mode is set during a time period when the subject's activity level is "no", the bar 653 indicating the unmanned alert mode is displayed, so the watcher knows that the subject was out during this time period. Therefore, even if the subject is not very active, the watcher can recognize the subject's situation in more detail. As a result, the watcher can perform high-quality watching with less burden. In addition, the bar 652 indicating the subject's activity level and the bar 653 indicating the set security mode are displayed on the same time axis, so the subject's activity level during the same time period and the set security mode can be visually recognized together.

[0068] Variations The present invention is not limited to the above-described embodiment. The above-described embodiment may be modified as in the following examples. In this case, two or more of the following modifications may be used in combination.

[0069] Variation 1 In the above-described embodiment, the activity amount of the subject and the security mode may be displayed side by side without being superimposed. FIG. 7 is a diagram showing an example of a daily screen 660A according to this modification. The screen 660A includes a graph 651 showing the activity amount of the subject in one day, similar to the screen 650A shown in FIG. 6. However, the bar 653 showing the set security mode is not superimposed on the graph 651. The screen 660A displays the bars 653 showing all the set security modes side by side with the graph 651. Unlike the screen 650A shown in FIG. 6, the screen 660A displays not only the bar 653 showing the unmanned security mode, but also the bar 653 showing the manned security mode and the bar 653 showing the release mode. The bar 653 is painted differently depending on the security mode. For example, the bar 653 has a different color, a different shade of color, or a different pattern depending on the security mode. The same display may also be performed on a weekly screen.

[0070] This display also allows the watcher to know that the subject was out during the time period when the subject's activity was not detected, so there is no need to check whether the subject was out during this time period. In addition, according to this modified example, even if a security mode other than the unmanned security mode was set during the time period when the subject's activity was not detected, the security mode set during this time period can be known. If the subject's activity is not detected during the time period when the subject is usually active and the manned security mode or the released mode is set, it is possible that some abnormality has occurred in the subject, so measures such as checking the subject's safety can be taken. In addition, if the released mode is set and there are many time periods when the amount of activity is low, the watcher can call on the subject to set the manned security mode.

[0071] Variation 2 In the above-described embodiment, the security mode is not always displayed, and may be displayed in response to the operation of the watcher. FIG. 8 is a diagram showing an example of a daily screen 670A according to this modified example. The screen 670A includes a graph 651 showing the amount of activity of the subject in one day, similar to the screen 650A shown in FIG. 6. However, the bar 653 showing the set security mode is not superimposed on the graph 651. When the watcher performs an operation to select a time period in which the amount of activity is "no" on the graph 651, the bar 653 showing the security mode set in that time period is displayed in response to this operation. The operation to select the time period may be, for example, an operation to touch an area corresponding to that time period on a touch panel. Alternatively, if the operation unit 604 includes a keyboard and a mouse, the operation to select the time period may be an operation to hover the mouse over the area corresponding to that time period or an operation to click on the area corresponding to that time period. The same display may also be performed on a weekly screen. According to this modified example, the amount of activity of the subject is easier to see than when the bar 653 showing the security mode is always displayed.

[0072] Variation 3 In the above-mentioned embodiment, the security mode may not be displayed at all times, but may be displayed as a pop-up in response to the operation of the watcher. FIG. 9 is a diagram showing an example of a daily screen 680A according to this modified example. The screen 680A includes a graph 651 showing the amount of activity of the subject in one day, similar to the screen 650A shown in FIG. 6. However, the bar 653 showing the set security mode is not superimposed on the graph 651. When the watcher performs an operation to select a time period in which the amount of activity is "no" on the graph 651, similar to the above-mentioned modified example 2, a balloon image 681 is displayed at a position where the selected time period and the starting point overlap in response to this operation. The selected time period and the security mode set for that time period are written in letters, numbers, or symbols on the balloon image 681. Also, a similar display may be performed on a weekly screen. According to this modified example, the amount of activity of the subject is easier to see than when the bar 653 showing the security mode is always displayed.

[0073] Variation 4 In the above-described embodiment, together with the activity amount of the subject, detection information (detection result or attribute information) regarding the sensor 100 that detected the activity that is a factor of the activity amount may be displayed. FIG. 10 is a diagram showing an example of a screen 690A on a daily basis according to this modified example. The screen 690A includes a graph 651 that shows the activity amount of the subject in one day, similar to the screen 650A shown in FIG. 6. However, the bar 653 that shows the set security mode does not need to be superimposed on the graph 651. For example, when the watcher performs an operation to select a time period from 8:00 to 10:00, in which the activity amount is "high", on the graph 651, the sensor 100 that detected the activity that is a factor of the activity amount in this time period, in other words, the sensor 100 that detected the activity that had a large effect on the measurement of the activity amount, is specified. In one example, the sensor 100 with the largest number of detections or the sensor 100 with a predetermined number of detections or more is specified. Then, a balloon image 691 is displayed at a position where the selected time period and the starting point overlap.

[0074] The detection result or attribute information of the specified sensor 100 is written in the balloon image 691 using characters, numbers, or symbols. The detection result of the sensor 100 includes a value detected by the sensor 100. The attribute information of the sensor 100 includes the type and installation location of the sensor 100. For example, if the cause of the "high" activity amount from 8:00 to 10:00 is detection by a human sensor installed in the living room and detection by a window sensor installed in the living room, a text message "detected by the human sensor in the living room and the window sensor in the living room" is written on the balloon image 691. This text message includes a character string "living room" indicating the installation location of the human sensor and the window sensor, and a character string "human sensor" and "window sensor" indicating the types of the human sensor and the window sensor. According to this modified example, the cause of the activity amount can be recognized along with the activity amount of the subject.

[0075] Variation 5 In the above-described embodiment, the bars 653 representing all the set security modes may be superimposed on the graph 651. Unlike the screen 650A shown in FIG. 6, not only the bar 653 representing the unmanned security mode, but also the bar 653 representing the manned security mode and the bar 653 representing the release mode are superimposed. In this modification, the bar 653 has a different color depending on the security mode. When the bars 652 and 653 are superimposed, it is preferable to synthesize the bars 652 and 653 so that both the shading of the bar 652 and the color of the bar 653 are visible. The same display may also be performed on a weekly screen. According to this display, the activity amount of the subject and the set security mode can be easily visually recognized for each time period. Also, the bar 653 representing the unmanned security mode and the bar 653 representing the manned security mode are superimposed on the graph 651, and the bar 653 representing the release mode may not be displayed. Here, the unmanned security mode and the manned security mode are collectively referred to as the security mode. In this way, the time period during which the deactivation mode was set may not be displayed, and only the time period during which the alert mode was set may be displayed.

[0076] Variation 6 In the above-described embodiment, the graph 651 is not limited to one that represents the amount of activity by the shade of color. The graph 651 may represent the amount of activity by different colors based on a feature other than the shade of color. For example, the graph 651 may represent the amount of activity by varying the color of the bar 652, or may represent the amount of activity by varying the pattern of the bar 652. Similarly, the bar 653 is not limited to one that represents the security mode by varying the pattern. As long as the bar 653 is displayed in a manner that can be distinguished from the bar 652 representing the amount of activity, the security mode may be represented by varying the shade of color of the bar 653, or the security mode may be represented by varying the color of the bar 653.

[0077] Variation 7 In the above-described embodiment, the unit of time for measuring the amount of activity may be longer than the unit of time used to display the graph 651. Here, it is assumed that the unit of time used to display the graph 651 is two hours. For example, when measuring the amount of activity in a time period from 10:00 to 12:00, the amount of activity is measured using detection information with the detection date and time being from 9:30 to 12:30. The amount of activity measured in this manner is displayed as the amount of activity from 10:00 to 12:00. In another example, when the difference in the amount of activity of the subject in adjacent time periods is equal to or greater than a threshold, the amount of activity of the subject may be changed in stages. For example, when the amount of activity from 6:00 to 8:00 is "small" and the amount of activity from 8:00 to 10:00 is "large," the density of the portion corresponding to the time period from 7:30 to 8:30 in the bar 652 representing the amount of activity from 6:00 to 8:00 and the bar 652 representing the amount of activity from 8:00 to 10:00 may be changed to a second density representing the amount of activity "medium." According to this modified example, the amount of activity of the subject can be displayed without unnatural changes.

[0078] Variation 8 In the above-mentioned embodiment, the graph representing the amount of activity is not limited to the graph 651 consisting of a bar 652. The graph representing the amount of activity may be a circular graph or a graph of another shape, as long as the amount of activity in each time period is represented by coloring the components. Furthermore, the method of displaying the amount of activity is not limited to displaying by a graph. For example, the amount of activity of the subject in a predetermined period and the set security mode may be displayed in a table format. In one example, the table is composed of rows of time periods, columns of activity amounts, and columns of security modes. In the row of each time period, a character string indicating the amount of activity in that time period is written in the cell corresponding to the column of activity amounts, and a character string indicating the security mode set in that time period is written in the cell corresponding to the column of security modes. This display also allows the subject's situation to be recognized in more detail even when the subject is not very active.

[0079] Variation 9 In the above-described embodiment, the amount of activity may be measured based on the number of detections of the sensor 100 and the type of the sensor 100. In one example, the number of detections of the sensor 100 may be weighted according to the type of the sensor 100. This is because the activity detected by the sensor 100 varies depending on the type of the sensor 100, and therefore, even if the number of detections is the same, the amount of activity of the subject may differ. For example, a human sensor detects the movement of the subject even if the subject moves even slightly, so when the activity of the subject is detected by the human sensor, the activity of the subject is considered to be low. Therefore, the number of detections of the human sensor may be weighted using a weighting factor smaller than 1. In one example, the number of detections of the human sensor is weighted using a weighting factor of "0.5". In this case, the number of detections of the human sensor is one every time the human sensor detects two times.

[0080] On the other hand, since the window / door sensor detects the subject's active action of opening the door, when the window / door sensor detects the subject's activity, the subject's activity is considered to be greater than when the human presence sensor detects the subject's activity. Therefore, the number of detections by the window / door sensor is not weighted. Therefore, the number of detections by the human presence sensor is one for each detection by the window / door sensor. In addition, for the sensor 100 that detects an activity that is considered to be a high activity, the number of detections may be weighted using a weighting coefficient greater than 1.

[0081] According to this modification, the number of detections by the type of sensor 100 that detects activities with a high amount of activity is greater than the actual number of detections, and the number of detections by the type of sensor 100 that detects activities with a low amount of activity is less than the actual number of detections. This allows a more accurate measurement of the amount of activity even if there is a difference in the amount of activity detected by the type of sensor 100.

[0082] In this modification, instead of weighting the number of detections by the sensor 100, a threshold value used to measure the subject's activity amount may be changed depending on the type of the sensor 100. For example, instead of weighting using a weighting coefficient greater than 1, the threshold value may be changed to be smaller. When the threshold value is smaller, a larger activity amount is more likely to be measured. On the other hand, instead of weighting using a weighting coefficient smaller than 1, the threshold value may be changed to be larger. When the threshold value is larger, a smaller activity amount is more likely to be measured.

[0083] Variation 10 In the above-described embodiment, the amount of activity may be measured based on the number of detections by the sensor 100 and the installation location of the sensor 100. In one example, the number of detections by the sensor 100 may be weighted depending on the installation location of the sensor 100. This is because there are cases where the subject's activity can be estimated to be high depending on the installation location of the sensor 100 that detected the subject's activity.

[0084] For example, since the outdoor sensor 100 detects the activity of a subject who goes outside, when the outdoor sensor 100 detects the activity of the subject, the activity of the subject is considered to be high. Therefore, the number of detections by the outdoor sensor 100 may be weighted using a weighting factor greater than 1. In one example, the number of detections by the outdoor sensor 100 is weighted using a weighting factor of "2". In this case, the number of detections by the outdoor sensor 100 is two for each detection by the outdoor sensor 100. However, when the security mode is an unmanned security mode or when the door sensor detects the opening of the front door, the subject detected by the outdoor sensor 100 may be a person other than the subject. Therefore, in such cases, weighting is not performed.

[0085] In addition, when multiple sensors 100 installed in different rooms each detect the subject's activity within a predetermined time, the number of detections of any of these sensors 100 may be weighted using a weighting factor greater than 1. In one example, when a sensor 100 installed on the first floor and a sensor 100 installed on the second floor each detect the subject's activity within 5 minutes, the number of detections of the sensor 100 installed on the first floor is weighted using a weighting factor of "2". In this case, the number of detections of the sensor 100 installed on the first floor is two if the sensor 100 installed on the first floor detects once. In addition, when the distance between the installation locations of multiple sensors 100 that detect the subject's activity within a predetermined time is large, it is considered that the subject moves a lot. In this case, the weighting factor may be large.

[0086] Conversely, when the same sensor 100 detects the subject's activity consecutively, it means that the subject's activity is low. For example, when the same window sensor detects the opening and closing of a window within 5 minutes, it indicates that the subject opened the window and then immediately closed it, so the subject's activity is considered to be low. Therefore, when the same sensor 100 detects the subject's activity consecutively, the number of detections of this sensor 100 may be weighted using a weighting factor smaller than 1. In one example, the number of detections of the sensor 100 that continuously detects the subject's activity is weighted using a weighting factor of "0.5". In this case, the number of detections of this sensor 100 is 1 for every 2 detections by this sensor 100.

[0087] According to this modification, when the subject's activity is estimated to be high depending on the installation location of the sensor 100 that detected the subject's activity, the measured activity amount is large. Conversely, when the subject's activity is estimated to be low depending on the installation location of the sensor 100 that detected the subject's activity, the measured activity amount is small. Therefore, it is possible to measure the activity amount more accurately.

[0088] In this modified example, instead of weighting the number of detections by the sensor 100, a threshold value used to measure the subject's activity amount may be changed depending on the installation location of the sensor 100. For example, instead of weighting using a weighting coefficient greater than 1, the threshold value may be changed to be smaller. When the threshold value is smaller, a larger activity amount is more likely to be measured. On the other hand, instead of weighting using a weighting coefficient smaller than 1, the threshold value may be changed to be larger. When the threshold value is larger, a smaller activity amount is more likely to be measured.

[0089] Furthermore, the above-described embodiments and modifications may be combined to weight the number of detections by the sensor 100 depending on the type of the sensor 100 and the installation location.

[0090] Variation 11 In the above-described embodiment, the activity amount corresponding to the posture of the subject detected by the sensor 100 may be measured. Specifically, the measuring means 412 measures a second activity amount for each time period according to the posture of the subject detected by the TOF sensor or the ultrasonic sensor, separately from the activity amount (hereinafter referred to as the "first activity amount") measured in the above-described embodiment. Specifically, for each time period, the measuring means 412 extracts, from the storage unit 402, detection information of the TOF sensor and the ultrasonic sensor whose detection date and time are included in the time period. Next, the measuring means 412 counts the number of detections of the posture of the subject by the TOF sensor or the ultrasonic sensor in the time period for each type of posture, using the extracted detection information. In this example, the types of posture include standing, sitting, and lying. Next, the measuring means 412 calculates the ratio of the number of detections of the standing posture to the number of detections of all postures. Then, the measuring means 412 measures the second activity amount of the subject by comparing the calculated ratio with a preset threshold value.

[0091] Here, the threshold value used for measuring the second activity amount is 15%. For example, when the postures of the subject detected in a certain time period are only sitting or lying, the ratio of the number of times the subject is detected in the standing position is 0%, and the activity amount is measured as "small". On the other hand, when postures including the standing position of the subject are detected in a certain time period, and the ratio of the number of times the subject is detected in the standing position among the number of times all postures are detected is greater than 0% and less than 15%, the activity amount is measured as "medium". Also, when postures including the standing position of the subject are detected in a certain time period, and the ratio of the number of times the subject is detected in the standing position among the number of times all postures are detected is 15% or more, the activity amount is measured as "large".

[0092] Also, the final activity amount may be measured by a combination of the first activity amount and the second activity amount. In one example, when the first activity amount and the second activity amount are the same, the activity amount is measured as the final activity amount. On the other hand, when the first activity amount and the second activity amount are different, and either one is "large", the final activity amount may be measured as "large". Also, when the first activity amount and the second activity amount are different, and either one is "small", the final activity amount may be measured as "small". Furthermore, only the second activity amount may be used instead of the first activity amount. According to this modified example, the activity amount of the subject can be measured more accurately by taking into account the posture of the subject.

[0093] Furthermore, when the second activity amount is measured, the detection result or attribute information of the sensor 100 that detected the activity that is the cause of the second activity amount may be displayed together with the activity amount of the subject. In one example, in the screen 690A shown in FIG. 10, when the cause of the second activity amount being "high" from 8:00 to 10:00 is the detection of a standing posture by a TOF sensor or an ultrasonic sensor installed in the living room, a text message "The user was walking around in the living room" may be written on the balloon image 691. In another example, when the cause of the second activity amount being "low" in a certain time period is the detection of a sitting posture by a TOF sensor or an ultrasonic sensor installed in the living room, a text message "The user was sitting and resting in the living room" may be written on the balloon image displayed in response to an operation of selecting this time period.

[0094] Variation 12 In the above-described embodiment, the activity amount of the subject may be measured based on the number of detections by the sensor 100 having the highest number of detections in each time period. Here, the threshold for the "high" activity amount is 5 times, the threshold for the "medium" activity amount is 2 times, and the threshold for the "low" activity amount is 1 time. For example, if the number of detections by the window sensor is 3 times, the number of detections by the human sensor is 1 time, and the number of detections by the door sensor is 1 time from 14:00 to 16:00 on December 1, 20XX, the sensor 100 having the highest number of detections is the window sensor. In this case, the number of detections by the window sensor is 2 times or more and less than 5 times, so the activity amount is measured as "medium".

[0095] Variation 13 In the above-described embodiment, the information used to measure the amount of activity is not limited to the detection information of the sensor 100. For example, the number of operations of the security mode may be used in addition to the detection information of the sensor 100. Changing the security mode means that the subject is likely to perform an activity such as moving. Therefore, it can be said that the greater the number of operations of the security mode, the greater the amount of activity of the subject. This number of operations of the security mode is calculated based on the security mode information. This number of operations of the security mode may include not only the number of operations to change the security mode, but also the number of cancellation operations to invalidate the detection information of the corresponding sensor 100 when the subject wants to open a window or front door in the manned security mode, for example.

[0096] Variation 14 In the above-mentioned embodiment, the functions of one device may be distributed among a plurality of devices, or the functions of a plurality of devices may be collectively included in one device. For example, the controller 200 has both a function of monitoring intrusions into the monitored area and a function of watching over the subject. However, instead of the controller 200, a first controller having a function of monitoring intrusions into the monitored area and a second controller having a function of watching over the subject may be used.

[0097] Variation 15 In the above-described embodiment, the activity amount and security mode of the subject may be displayed without using a graph. For example, the activity amount and security mode for each time period may be displayed in chronological order using a table with the horizontal axis representing each time period of the day (0:00 to 24:00) and the vertical axis representing the activity amount and security mode.

[0098] Variation 16 In the above-described embodiment, the subject of the function of the watching over monitoring system 10 is an example, and is not limited to this example. The function of the server device 400 may be included in the controller 200 or the terminal device 600. In other words, the process 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, the measurement means 412, and the transmission means 413 of the server device 400 may be included in the controller 200 or the terminal device 600.

[0099] Variation 17 In the above-described embodiment, the operation of the monitoring system 10 is not limited to the above-described example. The order of the processing steps of the monitoring system 10 may be changed as long as there is no contradiction. In addition, some of the processing steps of the monitoring system 10 may be omitted.
