Japanese Unexamined Patent Publication No. 2007-179378

When an alarm is issued, this type of safety monitoring system has a large effect on the surroundings, and the accuracy of safety judgment is important. For example, if it is determined that an abnormality has occurred based on the sensor information, even if the person being watched over (the person being watched over) does not actually have a problem, the person watching over will be notified of the occurrence of the abnormality. The watcher must take some action. On the other hand, if there is a problem with the person to be monitored for safety, it is required to reliably notify the occurrence of the abnormality, so it is difficult to make it difficult to determine that the abnormality has occurred based on the sensor information.

An object of the present invention is to provide a server device and a program capable of accurately determining the situation of a person to be watched (watched person).

The server device according to the present embodiment is installed in a house where a safety watcher lives, and is housed in a battery box of a battery-powered device that operates according to a predetermined life behavior of the watcher, and is a battery-powered device. It is connected to the battery-powered communication device that detects the operation of the above via the Internet network, and is connected to the first portable information communication terminal owned by the guardian via the Internet network and the public telephone network. It is connected to a second portable information communication terminal owned by the watcher who watches over the watcher via the Internet network. When the battery-type communication device detects the operation of the battery-powered communication device, the first type of life behavior data transmitted from the battery-type communication device is received via the Internet network, and the watcher is the first portable type. A receiver that receives the second type of life behavior data transmitted from the first portable information communication terminal when a specific operation is performed on the information communication terminal via the Internet network, and the first type of life behavior data. The state in which the battery-powered device does not operate and no specific operation is performed on the first portable information communication terminal continues based on the presence / absence of reception and the reception / absence of the second type of living behavior data. An estimation unit that estimates the length of time spent as non-living activity time, and when the non-living activity time reaches a preset safety confirmation time, a call is made to the first portable information communication terminal via a public telephone network. When the transmission unit that makes a call and the time when the first portable information communication terminal does not receive power for a telephone call reaches a predetermined time limit, a message indicating that the second portable information communication terminal does not receive power is sent. When the first portable information communication terminal receives power for a call and the first portable information communication terminal performs a predetermined button operation, the second portable information communication terminal is watched over. When a message indicating that an abnormal situation has occurred is sent to the user, the first portable information communication terminal receives power for a call, and the first portable information communication terminal does not operate a predetermined button. The second portable information communication terminal is provided with a transmission unit that does not transmit any message.

The safety monitoring service provided by the safety monitoring server device according to the present embodiment determines an abnormal situation of the target person based on the living behavior of the watched person (hereinafter referred to as the target person) who is watching the safety, and the determination result. Is transmitted to a portable information communication terminal such as a smartphone owned by a watcher (hereinafter referred to as a watcher) who watches over the target person or an information processing terminal of a security company contracted by the watcher as needed. As a result, for example, a user who is a watcher who uses the safety watch service can always watch whether or not an abnormality has occurred in the parents who are the target of the safety watch.

Hereinafter, the safety monitoring server device according to the present embodiment will be described with reference to the drawings. In the following description, components having substantially the same function and configuration are designated by the same reference numerals, and duplicate explanations will be given only when necessary.

As shown in FIG. 1, the safety monitoring system includes a safety monitoring server device 11 for providing a safety monitoring service. A portable information communication terminal 21 having a call function such as a smartphone owned by the target person and a portable information communication terminal such as a smartphone owned by the watcher with respect to the safety monitoring server device 11 via the Internet network 13. 29 is connected. Hereinafter, the portable information communication terminal 21 owned by the target person is distinguished as the target person terminal 21 and the portable information communication terminal 29 owned by the watcher as the watcher terminal 29. The battery-type communication device 23 is wirelessly connected to the safety monitoring server device 11 via the target person terminal 21. The subject terminal 21 and the battery-powered communication device 23 (23-1, 23-2) are wirelessly connected under the Bluetooth® standard as a short-range wireless communication standard.

An application program (target person application) on the target person side related to the safety monitoring service is installed on the target person terminal 21. The target app is always running in the background. The application determines that any of a plurality of specific operations set in advance for the target person terminal 21 has been performed by the target person, and generates life behavior data (type 2) each time, and the server device 11 Send to. The living behavior data includes an operation identification code, an operation time, and a target person terminal ID for identifying the target person terminal 21.

Specifically, the application program installed on the target person terminal 21 detects, for example, an operation of unlocking the target person terminal 21 (unlocking operation) as a specific operation on the target person terminal 21, and the detected life. A code indicating the action type "unlock operation" is generated together with the operation time (time code) and the terminal ID, and the living action data is transmitted to the safety monitoring server device 11. In addition, the application program installed on the target person terminal 21 detects an operation (charging operation) for charging the target person terminal 21 as a specific operation for the target person terminal 21, and sets the detected life behavior type "charging operation". Living behavior data is generated from the indicated code, operation time (time code), and terminal ID, and is transmitted to the safety monitoring server device 11. Further, the target person terminal 21 detects that the number of steps counted by the target person terminal 21 has reached a preset predetermined number, and detects a code indicating the type of the detected daily activity "walked a predetermined number of steps". Living behavior data is generated from the time (time code) and the terminal ID, and is transmitted to the safety monitoring server device 11. Further, the target person terminal 21 receives the life behavior data generated by the battery-powered device 25 from the battery-type communication device 23 and transfers it to the safety monitoring server device 11.

In the above, when any one of the three life actions of the target person (“unlock operation”, “charging operation”, and “walking a predetermined number of steps”) is performed, the target person terminal 21 outputs the life behavior data. Although it is said that the data is transmitted to the safety monitoring server device 11, the number and types of daily activities are not limited to the above. By increasing the number of daily activities, it is possible to improve the accuracy of detecting the presence or absence of abnormalities in the subject. Further, the specific operation is not limited to the "unlock operation" and the "charging operation". For example, the start operation of the specific application software installed on the target person terminal 21 and the power on / off operation. And so on.

The plurality of battery-type communication devices 23 attached to the TV remote controller or the like in the house where the target person resides are not limited to the form of connecting to the Internet network 13 via the target person terminal 21, and the battery-type communication device 23 is not limited to the form. May be in the form of directly connecting to the Internet network 13. Further, the target person terminal 21 does not function as a gateway of the battery-type communication device 23, but a wireless communication device that functions as a gateway may be installed in the target person's house. Further, although FIG. 1 shows two battery-powered communication devices 23-1 and 23-2, any number of battery-powered communication devices can be installed in the house where the subject resides.

The battery-type communication device 23 (23-1, 23-2) has a shape and size conforming to the battery standard, and a plurality of batteries used or installed indoors or outdoors in the house where the subject resides. It is installed in the battery box of the drive device 25 (25-1, 25-2), respectively. The battery-powered device 25-1 shown in FIG. 1 shows an example of a device provided with a manual operation unit, and the battery-powered device 25-2 shows an example of a device provided with a sensor or a switch such as a motion sensor. ing. Battery-powered devices 25-1 equipped with a manual operation unit include, for example, remote controls for televisions, air conditioners, interior lights, battery-ignited stoves (gas ranges), battery-powered sphygmomanometers, electric toothbrushes, and fire alarms. , Neprise, etc. Examples of the battery-powered device 25-2 equipped with a sensor include an fragrance agent provided with a function of automatically spraying according to sensor detection, a refrigerator in which opening and closing of a door is detected by a sensor or a switch, a gate and a front door. There are sensor lights arranged in the passage between the doors, and motion sensors distributed indoors and outdoors.

The battery-type communication device 23 has a shape and size conforming to the battery standard. For example, the battery-type communication device 23-1 is configured as an AA type, and the battery-type communication device 23-2 is configured as a single type. The shape, size, etc. of the battery-type communication devices 23-1 and 23-2 are arbitrary depending on the type of battery used in the battery-powered device 25. Hereinafter, the configuration of the battery-type communication device 23-1 having the same appearance as that of the AA battery will be described. The description of the battery-type communication device 23-2 will be omitted on the assumption that the same electronic circuit as the battery-type communication device 23-1 is mounted only on the size of the housing 41 different from that of the battery-type communication device 23-1.

As shown in FIGS. 2A and 2B, the battery-type communication device 23-1 has a cylindrical housing 41 having a height and a diameter conforming to the AA battery standard. The outer positive electrode terminal 43 and the outer negative electrode terminal 44 are attached to the front and rear end faces of the housing 41 according to the AA battery standard. Inside the housing 41, a battery storage unit 42 for storing a smaller standard AAA battery (internal battery) is provided. The inner positive electrode terminal 45 and the inner negative electrode terminal 46 connected to the positive and negative terminals of the stored battery of the battery storage unit 42 are connected to the outer positive electrode terminal 43 and the outer negative electrode terminal 44, respectively.

The cylindrical central axis of the battery housing portion 42 is offset in the radial direction with respect to the cylindrical central axis of the housing 41. This offset ensures a small amount of space inside the housing 41. The electronic circuit board 47 that realizes various functions of the battery-type communication device 23-1 is housed in this small space. The peripheral surface portion of the housing 41 on the side opposite to the electronic circuit board 47 is cut out in an oval shape. The length of this notch is equal to or slightly shorter than that of the AAA battery, and the width is slightly wider than the width of the AAA battery. As a result, the AAA internal battery can be inserted and removed from the battery housing portion 42 through the notch.

FIG. 3 is an equivalent circuit diagram of an electronic circuit mounted on the electronic circuit board 47 of the battery-type communication device 23-1. FIG. 3 shows an example in which the battery-type communication device 23-1 is attached to the television remote controller 25-1 (battery-powered device 25-1). The inner positive electrode terminal 45 and the outer positive electrode terminal 43 are electrically connected, and the inner negative electrode terminal 46 and the outer negative electrode terminal 44 are also electrically connected. When a manual operation button such as a channel of the TV remote controller 25-1 is pressed, the internal current value of the electronic circuit board 47, here the current value between the inner negative electrode terminal 46 and the outer negative electrode terminal 44, fluctuates according to the load fluctuation. To do. In order to detect this internal current, a detection resistor 401 that converts the internal current into a voltage is provided. The voltage across the detection resistor 401 (detection voltage) is applied to the input terminal (inverting input terminal) of the comparator 407. The positive electrode voltage of the internal battery 48 is divided by the voltage dividing resistors 402 and 403 and applied as a reference voltage to the other input terminals (non-inverting input terminals) of the comparator 407. The comparator 407 compares the detected voltage with respect to the reference voltage. When a manual operation button such as a channel of the TV remote controller 25-1 is pressed, the detection voltage fluctuates. The voltage dividing resistors 402 and 403 are adjusted so as to detect that the comparison result of the comparator 407 changes according to the fluctuation of the detected voltage and the manual operation button is pressed. The DCDC converter 404 uses the battery voltage of the internal battery 48 housed in the battery housing 42 to generate the power supply voltage Vdd of the comparator 407 and the RFIC 405.

When it is detected from the comparison result of the comparator 407 that a manual operation button such as a channel of the TV remote controller 25-1 is pressed, the RFIC 405 has an identification number for identifying the battery-type communication device 23-1 (hereinafter, battery-type communication). Life behavior data (type 1) including the device ID) and the time code indicating the operation time for the TV remote controller 25-1 is transmitted to the target person terminal 21 via the antenna 406. The time code may be added by the target person terminal 21 or may be added by the safety monitoring server device 11. At this time, as a time code, a time between the transmission time or the operation time of the living behavior data and the transmission time may be added instead of the operation time for the TV remote controller 25-1. The living behavior data may include voltage data indicating a detection voltage (battery voltage) detected during manual operation.

As described above, in the battery-powered device 25-1 (television remote controller) provided with the manual operation unit, the battery-powered communication device 23-1 generates and transmits life behavior data when the manual operation button is pressed. .. Further, the battery-powered device 25-2 is a sensor light provided with a sensor, and the battery-powered communication device 23-2 is mounted on the battery-powered device 25-2. The battery-powered communication device 23-2 detects fluctuations in the internal voltage or internal current of the battery-powered device 25-2 that operates according to sensor detection, detects the operation of the battery-powered device 25-2, and uses this as an opportunity to live a life. The behavior data is generated and transmitted to the server device 11 via the target person terminal 21. By attaching the battery-powered communication devices 23-1 and 23-2 to the plurality of battery-powered devices 25-1 and 25-2 that operate in accordance with various living behaviors in this way, a wide range of living behaviors can be detected. be able to.

FIG. 4 shows a functional block of the safety monitoring server device 11. A server program related to the safety monitoring service for realizing these functions (means) in the safety monitoring server device 11 as a computer is installed. The safety monitoring server device 11 is equipped with a processor such as a CPU (Central Processing Unit), a memory for storing programs and data, a non-volatile storage device such as an HDD or SSD, and various hardware constituting a computer such as a communication device. .. The processor controls various hardware by executing a program corresponding to each function stored in the memory, and realizes a function corresponding to each function block shown in FIG.

The safety monitoring server device 11 includes a control unit 111, a life behavior data reception unit 113, a life behavior data storage unit 115, a telephone transmission unit 117, a notification unit 118, a timer unit 119, a timer control unit 121, a management table storage unit 123, and an hour. It has a chart creation unit 125 and an automatic voice data storage unit 126.

A plurality of life behavior data (type 1) transmitted from a plurality of battery-type communication devices 23 via the target person terminal 21, and a plurality of lifestyles transmitted from the target person terminal 21 as a trigger of a plurality of types of specific operations. When any one of the behavior data (type 2) was used in parallel with the behavior data (type 2) without any restrictions such as priorities, the subject executed the behavior. It is important to judge that. Based on the living behavior data, the control unit 111 executes a safety watching process for notifying the watching person (watching person terminal 29) of the response status to the safety confirmation of the target person as necessary.
The control unit 111 generates behaviors (living behaviors) that the subject should originally occur in his / her life, depending on whether or not the first type of living behavior data is received and whether or not the second type of living behavior data is received. The non-living behavior time is estimated as the "elapsed time since the last living behavior was executed", and when the estimated non-living behavior time reaches a preset time (safety confirmation time), the subject has an abnormality. It is determined that there is a possibility that an abnormal situation has occurred (process for determining the possibility of an abnormal situation occurring), and the target person (target person terminal 21) is confirmed by telephone to confirm the safety via the public network 14. Based on the response status of the target person to the safety confirmation notification (telephone call), it is determined whether notification to the watcher (watcher terminal 29) is necessary, and it is determined that notification is necessary. When this happens, a safety confirmation notice is typically sent to the watcher (watcher terminal 29) by a message such as an email.

The response of the target person to the safety confirmation call is, for example, "no power reception", "power reception without a predetermined operation (for example, pushing dial" 1 ")" and "predetermined operation" for the target person terminal 21. There is "power received by". In the present embodiment, for example, in the case of "no power reception" and "power reception by a predetermined operation", it is determined that it is necessary to send a safety confirmation notice to the watcher.

The living behavior data receiving unit 113 receives the living behavior data from the target person terminal 21. The living behavior data received by the living behavior data receiving unit 113 is registered in the living behavior data storage unit 115 in chronological order.

The living behavior data storage unit 115 stores the living behavior data received by the living behavior data receiving unit 113. In the living behavior data storage unit 115, the living behavior data is managed for each subject. As shown in FIG. 5, the living behavior data storage unit 115 stores a living behavior history table in which the date and time are associated with the living behavior type. One record in the life behavior history table shows one life behavior of the subject. The living behavior type identifies the living behavior of the target person, and includes "unlocking operation", "charging operation", "walking a predetermined number of steps", "TV remote control operation", "sensor light operation", and the like. ..

In the living behavior history table, the time when the target person's non-living behavior time reaches the safety confirmation time, the time when the confirmation notification is sent to the target person, the time when the target person receives the power for the confirmation notification, and after receiving the power. The response content of the above and the transmission time at which the safety confirmation notification is sent to the watcher may be managed.

When the non-living activity time reaches the safety confirmation time, the telephone calling unit 117 confirms the safety of the target person (target person terminal 21) based on the target person's telephone number set in the management table (described later). To make a call for, and receive a response from the target person terminal 21 to this call. The telephone transmission unit 117 notifies the target person of voice guidance using the voice data stored in the automatic voice data storage unit 126 by telephone transmission, and prompts the target person to take measures to confirm his / her safety.

When it is determined that the safety confirmation is necessary, the notification unit 118 transmits the safety confirmation notification to the watcher (watcher terminal 29) based on the watcher notification destination set in the management table. Further, the notification unit 118 transmits the time chart data to the target person terminal 21 and the watcher terminal 29 in response to the request for acquisition of the time chart from the target person terminal 21 and the watcher terminal 29.

The timer unit 119 is for measuring the time, for example, a predetermined time (safety confirmation) for determining the situation of the target person based on the living behavior data received by the living behavior data receiving unit 113. It is used when measuring time).

The timer control unit 121 controls the start and reset of the time measurement by the timer unit 119.

The management table storage unit 123 stores a management table in which various data necessary for using the safety monitoring service are registered. For example, in the management table, information about the battery-type communication device 23 housed in the battery box of the battery-powered device 25 used in the target person's house, information about the telephone address to the target person, and the notification destination to the watcher Contains information about. For example, the management data is created based on the registration data input by the target person or the watcher who has accessed the registration page provided by the safety watching service using the target person terminal 21 or the watcher terminal 29.

FIG. 6 shows an example of the management table. For example, in the management table, with respect to the user ID that uses the safety monitoring service, the target person terminal ID for identifying the target person terminal 21, the battery-type communication device ID for identifying the battery-type communication device 23, and the like. The name of the battery-powered device 25 to which the battery-type communication device 23 is mounted (battery-powered device name), and the telephone number used in the public network 14 of the target person terminal 21 owned by the target person (target person's telephone number). , The watcher's contact information indicating the watcher's contact information (telephone number of watcher terminal 29, e-mail address, user ID of SNS (Social Networking Service), etc.), and the safety of the target person is determined to be necessary. The reference time (safety confirmation time), the time to wait for the target person to receive power when making a call to the target person for safety confirmation (power reception limit time), and the time zone during which the target person can be called. The data related to the indicated telephone valid time zone is registered in association with each other.

By referring to the management table, the control unit 111 can identify the target person by the target person terminal ID included in the life behavior data received by the life behavior data receiving unit 113. Further, by referring to the management table, the control unit 111 can determine which battery-powered device 25 has operated based on the battery-type communication device ID included in the living behavior data. Further, the control unit 111 can determine the living behavior of the target person by the living behavior type or the battery-type communication device ID included in the living behavior data.

The number of watcher notification destinations is not limited to one, and may be multiple. Further, the target person's telephone number is typically the telephone number of the target person's terminal 21, but may be the telephone number of a fixed telephone installed in the house. Further, it is not necessary to use the battery-type communication device 23 corresponding to all the battery-type communication device IDs registered in the management table for the safety monitoring process. For example, the device to be used is selected according to the instruction from the watcher terminal 29. You may be able to do it. In this case, it is assumed that the data indicating the device used for the safety monitoring process is associated with the battery-type communication device ID in the management table. As a result, a battery-powered communication device (battery-powered device) that can detect the behavior of the target person can be appropriately used, and when the behavior pattern of the target person changes (for example, not watching TV), the battery Even if the drive-type device 25 fails, it can be flexibly dealt with. This contributes to improving the accuracy of determining the occurrence of an abnormality in the subject.

The time chart creation unit 125 creates a time chart (time chart) based on the life behavior data stored in the life behavior data storage unit 115. The time chart data created by the time chart creation unit 125 is transmitted to the target person terminal 21 and the watcher terminal 29 in response to the time chart acquisition request from the target person terminal 21 and the watcher terminal 29. To. As a result, the timetable diagram as shown in FIG. 7 is displayed on the target person terminal 21 and the watcher terminal 29.

As shown in FIG. 7, the time chart shows the life behavior history of the subject collected by the subject terminal 21. The life activity history includes the operation history of the battery-powered device (TV remote controller) 25-1, the operation history of the battery-powered device (sensor light) 25-2, the unlock operation history of the target person terminal 21, and the target person terminal 21. The charging operation history and the step count history of the target person holding the target person terminal 21 are included. In each history, "○" is written at the position corresponding to the time when the activity of daily living was performed. As a result, the watcher can confirm what kind of life behavior the subject performed at what time. By being able to confirm the living behavior of the subject, the watcher can catch a sign that an abnormality will occur in the subject. For example, if the TV remote controller 25-1 is operated for a long time during the normal sleeping hours, the watcher can predict that something is wrong with the subject and is actually safe. Before the abnormality is detected by the monitoring service, it is possible to take measures such as taking the subject to the hospital. In the time chart shown in FIG. 7, the date to be displayed on the time chart can be changed by tapping the calendar button. The display form of the time table shown in FIG. 7 is an example, and other display forms can be used. For example, the time chart may include information regarding the transmission time of the confirmation notification to the target person, the content of the response to the confirmation notification, and the transmission of the safety confirmation notification to the watcher. As a result, the watcher can retroactively confirm when the above-mentioned event occurred, and even though no abnormality has occurred, the situation in which the non-living action time reaches the safety confirmation time is repeated. At this time, the watcher can easily change the battery-powered device 25 to which the battery-powered communication device 23 is mounted, and can easily update the safety confirmation time to a longer time. This contributes to improving the accuracy of determining whether or not the subject has an abnormality.

Next, the operation of the safety monitoring server device 11 according to the present embodiment will be described. FIG. 8 shows a safety monitoring processing procedure by the safety monitoring server device 11 according to the present embodiment. In using the safety monitoring service, it is assumed that the target person application is running on the target person terminal 21. Further, it is assumed that the watcher logs in to the safety watch service using the user ID and various information managed in the management table shown in FIG. 6 is registered.

The control unit 111 starts the safety monitoring process of the target person when the start button on the service screen of the safety monitoring service displayed on the watcher terminal 29 is tapped by the watcher. The control unit 111 refers to the management table, sets the safety confirmation time associated with the user ID, and instructs the timer control unit 121 to start the timer unit 119 (step S1). As a result, the measurement of the elapsed time is started. The time measured by the timer unit 119 is the time during which the subject is not performing a living behavior (non-living behavior time), and is, for example, the elapsed time since the last reception of the living behavior data.

The control unit 111 waits for the reception of the living behavior data until the elapsed time reaches the safety confirmation time (step S2; No, step S4; No). When the living behavior data is received before the elapsed time reaches the safety confirmation time (step S2; Yes), the control unit 111 instructs the timer control unit 121 to reset the elapsed time. The timer control unit 121 resets the time measurement by the timer unit 119 in response to an instruction from the control unit 111 (step S3). Then, the process returns to step S1, and the control unit 111 instructs the timer control unit 121 to start measuring the elapsed time. The timer control unit 121 starts the time measurement by the timer unit 119 in response to the instruction from the control unit 111.

In this way, if the living behavior data can be received before the elapsed time reaches the safety confirmation time, the subject is keeping his / her daily life calm, that is, the subject has no abnormality. I can judge. Unless the elapsed time reaches the safety confirmation time, the confirmation notification will not be sent to the target person, and the confirmation required notification will not be sent to the watcher.

If the living behavior data is not received before the elapsed time (non-living behavior time) reaches the safety confirmation time (step S4; Yes), the control unit 111 may have an abnormality in the subject. Is determined. The control unit 111 instructs the timer control unit 121 to reset and stop the time measurement. The timer control unit 121 resets the time measurement by the timer unit 119 and waits for the start of the time measurement by the timer unit 119 in response to the instruction from the control unit 111 (step S5).

When the elapsed time reaches the safety confirmation time (current time) is not the telephone valid time zone (telephone callable time zone) set for the target person in advance (step S6; No), the control unit 111 , The notification destination of the watcher is specified by referring to the management table, and the notification unit 118 sends a message to the watcher (watcher terminal 29) to notify that the elapsed time has reached the safety confirmation time. (Step S7). The telephone valid time zone is set in advance by the target person or the watcher, for example, in the midnight time zone during sleep when it is difficult to answer the telephone, or in the time zone when the person goes out regularly. By setting a valid phone time zone, it is possible to avoid the situation where the call is unnecessarily woken up by the phone for confirmation notification and the situation where the call is received when it is difficult to answer the phone while on the go, and the mental stress of the target person. Can be suppressed. However, there is a possibility that an abnormality has actually occurred in the target person even outside the telephone valid time zone. Therefore, the target person is not called to confirm the safety, but the watcher is notified that the elapsed time has reached the safety confirmation time. The watcher can pay attention to the situation of the target person by receiving the message sent from the safety watching server device 11 notifying the possibility of abnormality of the target person at the watcher terminal 29. For example, the watcher may take measures such as calling the target person or visiting the target person if the target person has complained of the problem for some time, and the target person has not complained of any particular problem. In that case, it is sufficient to continue to wait for the notification from the safety monitoring service without taking any action.

When the elapsed time reaches the safety confirmation time (current time) is the telephone valid time zone set for the target person (step S6; Yes), the control unit 111 refers to the management table and refers to the management table. The telephone number of the target person is specified, and the telephone calling unit 117 causes the target person (target person terminal 21) to make a telephone call for confirming the safety (step S8).

When the telephone transmission unit 117 receives power from the telephone transmission to the target person terminal 21 (step S9; Yes), the telephone transmission unit 117 uses the voice data stored in the automatic voice data storage unit 126, for example, "This is watching over. It is a service. I am calling because I could not confirm the use of the watching device for a certain period of time. If there is no problem, please hang up as it is. If you have any problems, press the dial button "1". If you press it, we will contact the family members who are watching over you. ”(Step S10), prompting the target person to take action to confirm their safety.

Here, when the communication is disconnected by the target person without pressing the dial button "1" for the target person terminal 21 (step S11; No), the telephone calling unit 117 is disconnected from the control unit 111. Notify that. The control unit 111 determines that no abnormality has occurred in the target person by disconnecting the telephone call for safety confirmation without performing a predetermined operation due to receiving power, and it is necessary for the watcher. The process is returned to step S2 without transmitting the safety confirmation notification, and the safety monitoring process for the target person is continued.

On the other hand, when the target person presses the dial button "1" on the target person terminal 21 (step S11; Yes), the telephone call unit 117 detects that the dial button "1" has been operated. Notify the control unit 111. The control unit 111 determines that an abnormality has occurred in the target person due to the predetermined operation being performed with power received, identifies the notification destination of the watcher by referring to the management table, and the notification unit 118 informs the person. The watcher (watcher terminal 29) is made to send a message for notifying that an abnormality has occurred (step S12).

In the above description, the operation of pressing the dial button "1" is taken as an example of the predetermined operation after receiving the power for the telephone call for confirming the safety, but other operations can also be used. .. In addition, a plurality of predetermined operations may be set so that the content of the problem occurring in the target person can be notified by the difference in the operation. In this case, it is possible to include the content of the abnormality occurring in the target person in the message sent to the watcher. When the watcher receives the message sent from the safety watching server device 11 notifying the abnormality of the target person at the watcher terminal 29, the watcher immediately responds to the target person (contacts to various places, the target person's house). You can make a visit to).

When there is no power received for the telephone call for confirming the safety of the target person (target person terminal 21) (step S9; No), the telephone caller unit 117 manages the elapsed time from the telephone call. Waiting for power reception until the power reception limit time set in the table is reached (step S13; No). If there is no power reception even after the power reception limit time is reached (step S13; Yes), the telephone transmission unit 117 determines that there is no power reception and notifies the control unit 111 of "no power reception".

The control unit 111 determines that the target person cannot receive power due to an abnormality caused by the determination of "no power reception", and refers to the management table to notify the watcher. After identifying, the notification unit 118 causes the watcher (watcher terminal 29) to send a message for notifying that there is no power reception (step S14). The watcher receives a message sent from the safety watching server device 11 notifying that the target person does not receive power at the watcher terminal 29, and immediately responds to the target person (contacting various places, target). You can make a visit to a person's house, etc.).

If the control unit 111 is set to continue the safety monitoring process after transmitting the safety confirmation notification (step S15; Yes), the control unit 111 returns the process to step S2 and continues the safety monitoring process of the target person. To continue. The setting of whether to continue the safety watching process can be appropriately changed according to an instruction from the watcher terminal 29 operated by the watcher.

If the control unit 111 is set not to continue the safety monitoring process after transmitting the safety confirmation notification (step S15; No), the control unit 111 ends the safety monitoring process of the target person. When the safety monitoring process is completed, the safety monitoring server device 11 restarts the safety monitoring process in response to an instruction from, for example, the watcher terminal 29.

In this way, the safety monitoring server device 11 determines whether the target person has operated the battery-powered device 25 used in the target person's house, or has performed a specific operation on the target person terminal 21. Determines the presence or absence of abnormalities in the subject based on multiple types of daily living behavior, such as whether or not he / she carried 21 and walked, and if there is a possibility that an abnormality has occurred in the subject, notify the watcher to that effect. be able to. Since the presence or absence of abnormal occurrence of the subject is judged based on multiple types of daily living behaviors, the accuracy is higher than the judgment based on a single living behavior.

In addition, whether or not the living behavior data (type 2) that can be acquired only by the target person terminal 21 is received and the living behavior data (first type) that can be acquired by the battery-type communication device 23 mounted on the battery-powered device 25 in the house. By estimating the time when the target person is not living, the target person is in the house but does not have the target person terminal 21 or the target person is in the house by combining with the presence / absence of reception of type 1). It is possible to flexibly respond to the case where the target person is in the terminal 21 but is not operating the target person terminal 21 or the target person is not in the house. By having a plurality of devices from which the living behavior data is acquired in this way, it is possible to improve the accuracy of determining whether or not the subject has an abnormality.

In addition, the safety monitoring server device 11 makes a phone call for confirming the safety of the target person when the living behavior of the target person cannot be confirmed, and responds to the call for confirming the safety of the target person. Since it is determined whether or not an abnormality has occurred, the situation of the target person can be surely grasped. The safety monitoring server device 11 notifies the target person of a message according to the response status of the target person to the telephone for confirming the safety of the target person if there is a possibility that the target person has an abnormality. You can definitely watch over the person, check the content of the message, and respond.

When using the safety monitoring service provided by the safety monitoring server device 11, prepare a portable information communication terminal 21 to be possessed by the target person and a battery-type communication device 23 to be attached to the battery-powered device 25 in the house. Just do it. Currently, the penetration rate of portable information and communication terminals such as smartphones is high, and in practice, a battery-powered communication device 23 is prepared and simply attached to a battery-powered device 25 such as a remote controller or a sensor light already in the house. Good. Therefore, the watcher does not need to purchase and install a special device such as a surveillance camera, and can reduce the trouble and cost of introducing the service. In addition, since life behavior data is collected using portable information and communication devices that the target person uses on a daily basis and battery-powered devices such as remote controls, the target person only has to perform daily life behavior. Often, the subject's mental stress on being watched can be relieved compared to the case where a surveillance camera is installed.
