Description

The present invention relates to a watching device and a watching method.

As a means of watching over accidents caused by wandering of elderly people or lost children, there is a method of having a device for transmitting location information wirelessly. In this method, it is necessary for the person to be watched over to surely wear the device, but when using a smartphone or the like, there is a risk that the device may be forgotten to be carried or the device may be dropped. On the other hand, the method of wrapping the device around the body with a band or the like with an emphasis on surely wearing the device may cause the watching subject to feel uncomfortable. For this reason, we have devised ways to ensure that the device is worn and that the person being watched over can continue to carry it without being aware of it, so that it can be made smaller and thinner so that it can be attached to things around us without discomfort. It has been done.

For example, Patent Document 1 discloses an invention of an insole including a personal information storage unit, a current position acquisition unit, a transmission unit, a vibration power generation unit, and a power storage unit. When the person to be watched wears this insole and the observer receives the data transmitted from the insole, the whereabouts of the person to be watched can be identified.

Japanese Patent No. 5978477

However, the watching method using the insole of Patent Document 1 has a problem that even if another person who is not the person to be watched wears the insole, it cannot be understood. For example, if another person mistakenly wears it or intentionally wears it on another person, the location information of that person may be disclosed to an unintended person or the spoofing may be overlooked. In addition, since the person continues to recognize that the person is being watched over by another person, there is also the problem that it is delayed to notice that the true location of the person being watched over is unknown.

The present invention has been made in view of the above problems, and provides a watching system capable of determining whether or not a watching person is a legitimate watching target person without causing discomfort to the watching target person. It is an object.

In order to solve the above problems, the monitoring device includes a wearing terminal management means, a reference walking data acquisition means, a walking data receiving means, and a wearer validity determination means. The wearing terminal management means acquires correspondence information between the person to be watched and the wearing terminal worn by the person to be watched. The reference walking data acquisition means acquires reference walking data that serves as a reference for walking data representing the walking characteristics of the person being watched over. The walking data receiving means receives the walking data transmitted from the wearing terminal. The wearer legitimacy determination means collates the received walking data with the reference walking data to determine whether the wearer of the wearing terminal is a legitimate watch target person.

The effect of the present invention is to be able to provide a watching system capable of determining whether or not the watching person is a legitimate watching target person without causing discomfort to the watching target person.

In the above configuration, it is possible to determine whether the wearer of the wearable terminal is a legitimate watch target person or another person by using the walking data acquired by the wearable terminal. Therefore, if the wearing terminal can be worn without discomfort, the person to be watched can watch over without feeling uncomfortable.

(Second embodiment)
FIG. 2 is a block diagram showing the monitoring system 1000 of the present embodiment. The watching system 1000 has a wearing terminal 100 and a watching server 200. The watching server 200 corresponds to the watching device 10 of the first embodiment.

The wearing terminal 100 has a wearing terminal identification information storage unit 110, a walking data acquisition unit 120, a position information acquisition unit 130, and a wearing terminal data transmission unit 140. The wearing terminal identification information storage unit 110 stores the identification information of the wearing terminal. The walking data acquisition unit 120 acquires walking data of the wearer wearing the wearing terminal. The walking data is data such as changes in acceleration and vibration measured when the wearer of the wearing terminal 100 walks. Since the walking data shows characteristics unique to the individual, it is possible to identify the individual using the walking data. Although the description of the individual identification method is omitted here, a method of analyzing walking data (vibration measurement data associated with walking) to identify a pedestrian is disclosed in, for example, International Publication No. 2017/188418. .. The position information acquisition unit 130 acquires the position information of the wearing terminal 100. Specifically, the position of the wearing terminal 100 is determined by receiving radio waves from satellites and communication base stations. The wearing terminal data transmitting unit 140 transmits the wearing terminal data including walking data and position information in association with the wearing terminal identification information to the monitoring server 200, for example, by radio.

The monitoring server 200 includes a wearing terminal management unit 210, a reference walking data acquisition unit 220, a wearing terminal data receiving unit 230, a walking data collation unit 240, a position information monitoring unit 250, and an unauthorized wearing notification unit 260. are doing.

The wearing terminal management unit 210 acquires the identification information of the wearing terminal and the association information with the person to be watched over. This association information may be stored in the wearing terminal management unit 210, or may be acquired from an external storage device or the like. The reference walking data acquisition unit 220 acquires the reference walking data that serves as a reference for the walking data of the person to be watched over. This reference walking data may be stored in the reference walking data acquisition unit 220, or may be acquired from an external storage device or the like. The wearing terminal data receiving unit 230 receives the wearing terminal data. The walking data collation unit 240 collates the received walking data with the reference walking data of the watching target person, and determines whether the wearing person is the watching target person associated with the wearing terminal.

The position information monitoring unit 250 monitors the position information of the wearing terminal 100. Then, when it is determined that the wearer is the person to be watched over, the position information of the wearable terminal is transmitted to the monitor terminal 300, which is a legitimate information receiving terminal registered in advance. The observer holding the observer terminal 300 is, for example, a facility staff member or a family member. On the other hand, if the wearer is not the person to be watched over, that is, the wearer is an illegal wearer, the position information is not transmitted to the monitor terminal 300, and the illegal wear notification unit 260 displays or voices the illegal wearer. Notify that it is worn. Targets to be notified are, for example, facility managers and security guards. The hardware of the wearing terminal 100 can be, for example, a portable communication device having a communication function, a processor, a memory, etc., and the hardware of the watching server 200 can be, for example, a computer having a communication function.

FIG. 3 is a table showing an example of the reference walking data table acquired by the reference walking data acquisition unit 210. In this example, the wearing terminal ID (column A), the person to be watched (column B), the reference walking feature (column C), the observer (column D), the observer address (column E), etc. are displayed in the reference walking data table. Information is retained. ID is an abbreviation for Identifier and identification information. The reference walking data is obtained by measuring the transition of acceleration when the watching target person walks and converting the standard walking trajectory and operating speed of the watching target person into data. The observer is, for example, a staff member of a facility to which the person to be watched belongs, a family member, or the like, who may disclose the personal information of the person to be watched. The contact information (e-mail address, etc.) is registered in advance as a legitimate contact information. In addition, the address / age / blood type / medical history and the like are stored in the column of other information.

FIG. 4 is a table showing an example of a storage table for the position information of the wearing terminal 100. The position information can be recalled later by recording it in the position information monitoring unit 250 together with the wearing terminal ID and the time in another table.

FIG. 5 is a flowchart showing the operation of the watching server 200. First, the reference walking data acquisition unit 210 reads out the reference walking data of the watching target person associated with the wearing terminal ID (S101). Next, the wearing terminal data receiving unit 220 receives the wearing terminal data (S102). The wearing terminal data includes the wearing terminal ID, walking data, and position information. The order of S101 and S102 may be reversed. Next, the position information monitoring unit 250 stores the position information of the wearing terminal 100 (S103). Next, the walking data collation unit 250 collates the received walking data with the reference walking data of the person to be watched (S104). The collation can be performed, for example, by repeating the acquisition of the walking data and the collation of the walking data and the reference walking data a predetermined number of times, and checking whether or not the condition of the predetermined similarity is satisfied. Here, if it is determined that the two match (S105_Yes), it is determined that the wearer is a legitimate watch target person, and the position information is transmitted to the observer terminal (S106). On the other hand, if the walking data of the wearer does not match (S105_No), the possibility of unauthorized wearing is monitored and the server 200 notifies the user (S107). This notification can be made so that only the facility manager and security guards can see it, for example.

As described above, according to the present embodiment, it is possible to determine whether the wearer of the wearing terminal is the correct person to be watched over, and to notify the observer of the position information only when the wearer is correct.

(Third Embodiment)
FIG. 6 is a block diagram showing the monitoring system 1001 of the present embodiment. The monitoring server 201 of the present embodiment has a similar walking data search unit 270 and an unauthorized wearing candidate output unit 280 in addition to the monitoring server 200 of the second embodiment. Further, a related party standard walking data acquisition unit 210a for acquiring standard walking data of related parties such as the staff of the facility to which the watching target person belongs and the family of the watching target person is provided.

In the watching system 1001, when the wearer of the wearing terminal 100 is not the watching target person corresponding to the wearing terminal ID, there is no other watching target person or a related person who mistakenly wears the wearing terminal 100. Can be searched.

If the received walking data does not match the reference walking data corresponding to the wearing terminal ID, it means that someone other than the corresponding watching target person is wearing the wearing terminal 100. At this time, the similar walking data search unit 270 reads out the reference walking data of another watching target person from the reference walking data acquisition unit 210, and searches for something that matches the received walking data. Here, if there is no match, the reference walking data acquired by the related party reference walking data acquisition unit 210a is searched for matching the received walking data. Then, when a match is found, the corresponding other watch target person or related person is determined to be an illegally attached candidate, and is output from the illegally attached candidate output unit by means such as display and printing. .. The above-mentioned match determination can be performed, for example, by satisfying a predetermined criterion for the degree of similarity.

FIG. 7 is a flowchart showing the operation of the watching server 201. In this flowchart, the operations of S101 and S102 in FIG. 5 are omitted. First, the position information monitoring unit stores the received position information in association with the wearing terminal ID (S201). Next, the walking data collation unit collates the received walking data with the reference walking data of the watching target person corresponding to the wearing terminal ID (S202). Here, when the walking data and the reference walking data match (S203_Yes), it is assumed that the wearer of the wearing terminal 100 is a legitimate watching target person, and the position information of the wearing terminal 100 is registered. It is transmitted to the monitored monitor terminal (S204).

On the other hand, when the received walking data and the reference walking data corresponding to the wearing terminal ID do not match (S203_No), the similar walking data search unit searches for other matching reference walking data. At this time, the data of the reference walking data acquisition unit and the related person reference walking data acquisition unit are searched (S205). Here, if a match is found (S206_Yes), the corresponding other watch target person or related person is output as an unauthorized installation candidate (S207). On the other hand, when there is no matching reference walking data (S206_No), since the wearer is unknown, only the possibility of unauthorized wearing is notified (S208).

According to the above operation, there is a high possibility that the candidate who is illegally attached can be quickly identified when the attached terminal is illegally attached. And, it is possible to accelerate the discovery of the correct watching target person.

(Fourth Embodiment)
FIG. 8 is a block diagram showing the monitoring system 1002 of the present embodiment. The wearing terminal 102 has a beacon 150 and a walking data acquisition / transmission control unit 160 in addition to the configuration of the wearing terminal 100 of the third embodiment. Further, the watching server 202 has a beacon information acquisition unit 290 and a wearing terminal operation control unit 292 in addition to the configuration of the watching server 201 of the third embodiment.

FIG. 9 is a schematic view showing that a plurality of watching target persons wearing the wearing terminal 102 exist in the facility area 2000, and the watching server 202 performs these watching. Beacon receivers 2100 are arranged in various places in the facility area. Beacon here means a position identification technology using low power consumption short-range radio. Then, here, it is assumed that the wearing terminal 102 periodically transmits a beacon signal, and the position of the wearing terminal 102 can be specified by receiving this signal at the beacon receiver 2100 installed in the facility area 2000. Further, when the wearing terminal 102 goes out of the facility area 2000, the beacon signal transmitted from the wearing terminal 102 does not reach the beacon receiver 2100.

The beacon information acquisition unit 290 of the monitoring server 202 acquires the beacon information from the beacon receiver in the facility area and identifies the position of the wearing terminal 102 which is the transmission source. The monitoring server 202 cannot acquire the beacon information from the wearing terminal 102 outside the facility area 2000, but as in the second and third embodiments, the watching server 202 receives the wearing terminal data to receive the wearing terminal 102. The position of can be specified. When it is determined from the received walking data that the wearer of the wearing terminal 102 is a legitimate watching target person, the watching server 202 uses the communication network 3000 as in the second and third embodiments. , The position information of the person to be watched over is transmitted to the observer terminal 300. In the example of FIG. 9, a plurality of observer terminals 300 (300--1, 300-2, ...) Are drawn.

The wearing terminal control unit 292 of the monitoring server 202 causes the walking data acquisition / transmission control unit 160 to stop the acquisition and transmission of walking data while the wearing terminal 102 is in the facility area 2000 and the beacon information can be acquired. Send a command. The walking data acquisition / transmission control unit 160 that receives this command controls the wearing terminal 102 so as to stop the acquisition and transmission of walking data. On the other hand, when the wearing terminal 102 goes out of the facility area 2000 and the beacon receiver 2100 cannot receive the beacon signal, the watching server 202 also cannot receive the beacon information. When the beacon information cannot be received, the wearing terminal operation control unit 292 transmits a command to the walking data acquisition / transmission control unit 160 to acquire and transmit the walking data. The walking data acquisition / transmission control unit 160 that receives this command controls the wearing terminal 102 to start acquiring and transmitting walking data. The radio waves used by the wearing terminal operation control unit 292 and the walking data acquisition / transmission control unit 160 for communication are stronger than the beacon and can reach outside the facility area 2000. Further, when the beacon signal received by the beacon receiver 2100 becomes weak, an alarm notifying the beacon signal may be notified to the monitoring server 202, and the walking data acquisition control may be started as a trigger.

In the example of FIG. 9, a plurality of persons to be watched wear the wearing terminals 102-1, 102-2, ..., And the wearing terminals 102-2 are outside the facility area 2000. The wearer wearing the wearing terminal 102 corresponds to, for example, an elderly person wandering around.

The above series of operations can be summarized as follows. When the wearer wearing the wearing terminal 102-2 leaves the facility area 2000, the beacon receiver 2100 cannot receive the beacon signal. Then, the watching server 202 determines that the wearer of the wearing terminal 102-2 has left the facility area 2000, that is, has started wandering. Then, the wearing terminal operation control unit 292 instructs the wearing terminal 102-2 to acquire the walking data and start transmitting the wearing terminal data. As a result, acquisition and transmission of walking data of the wearing terminal 102-2 and monitoring of position information are started. This monitoring is repeated until the wearing terminal 102-2 returns to the facility area 2000 and the beacon information is reacquired by the monitoring server 202. Then, while receiving the wearing terminal data, as in the second and third embodiments, an operation of determining whether the wearer is a legitimate watching target person and a person who illegally wears the wearing terminal. Search for. According to the above operation, while the wearing terminal is in the facility area, the wearing terminal does not acquire the position information, the walking data, the transmission of the wearing terminal data, etc., so that the power consumption of the wearing terminal is reduced. You can save. The watching system of the present embodiment is suitable for elderly care, child watching, worker / prisoner management, and the like.
