DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a tag carrying monitoring device, a tag carrying monitoring system, and a tag carrying monitoring method according to the present invention will be described in detail below with reference to the accompanying drawings.

<Overview of tag mobile monitoring system>
An overview of a tag carrying monitoring system including a tag carrying monitoring device according to this embodiment will be explained. FIG. 1 is an explanatory diagram for explaining an overview of a tag carrying monitoring system 100 including a tag carrying monitoring device 1 according to the present embodiment. The tag carrying monitoring system 100 according to the present embodiment allows a person to be monitored M, such as an elderly person who needs to be watched over, to carry a wireless tag 10, and when the person to be monitored M goes out, the movement line of the person to be monitored is tracked. It is a monitoring system.

As a premise of the tag-carrying monitoring system 100, the wireless tag 10 transmits a wireless signal containing identification information of its own tag. Outdoors, a communication terminal 50 such as a smartphone with a reception function located near the wireless tag 10 or a fixedly placed communication terminal 60 receives the wireless signal from the wireless tag 10 .

The communication terminal 50 is, for example, a communication terminal owned by a passerby A. Upon receiving the wireless signal from the wireless tag 10, the communication terminal 50 notifies the management server 30 of the location information of the monitored person M, including the identification information of the wireless tag 10 and the location information of the communication terminal 50, etc. The management server 30 notifies the communication terminal 40 of the person B related to the monitored person M of the location information or flow line information of the monitored person M, as necessary.

For the fixedly placed communication terminal 60, the management server 30 stores and manages the position information of the communication terminal 60 in advance, and when the communication terminal 60 receives the radio wave from the wireless tag 10, it receives the identification information of the wireless tag 10. The identification number of the communication terminal 60 itself is transmitted to the management server 30, the management server 30 reads out the stored location information of the communication terminal 60, and notifies the person B of the location information or flow line information. In this way, in the case of the fixedly arranged communication terminal 60, the location is fixed, so the location information is not transmitted each time.

The wireless tag 10 transmits a wireless signal using, for example, BLE (Bluetooth (registered trademark) Low Energy), which is a short-range wireless technology with low power consumption. On the other hand, the communication terminal 50 and the fixed communication terminal have a function of receiving a BLE wireless signal. Furthermore, the communication terminal 50 has a self-positioning function such as GPS.

As shown in FIG. 1, in the tag carrying monitoring system 100, a tag carrying monitoring device 1, a management server 30, a communication terminal 40, and a plurality of communication terminals 40 are connected to a network N. The tag carrying monitoring device 1 determines whether or not the monitored person M residing in the house H is carrying the wireless tag 10, and if the person is not carrying the wireless tag 10, the tag carrying monitoring device 1 issues a warning message urging the person to carry the wireless tag 10. conduct.

The tag carrying monitoring device 1 includes a controller 20, to which a wireless tag detection section 11, a person detection section 12, and an entrance/exit person detection section 13 are wirelessly connected. The wireless tag detection unit 11 is placed in the living space E of the house H, receives wireless signals from nearby wireless tags 10, estimates the distance to the wireless tag 10 based on the received field strength of the wireless signal, and detects the distance to the wireless tag 10 based on the received field strength of the wireless signal. Based on the change in distance, it is detected whether the wireless tag 10 has moved or not, and a detection signal corresponding to the detection result is transmitted to the controller 20 (S11). Further, the human detection unit 12 such as a human sensor detects whether or not a person in the living space E has moved, and transmits a detection signal corresponding to the detection result to the controller 20 (S12).

If the controller 20 does not detect movement of the wireless tag 10 and detects movement of a person, it determines that the person to be monitored M is not carrying the wireless tag 10 (S13). If the controller 20 determines that the person to be monitored M is not carrying the wireless tag 10, the controller 20 issues a warning to the person to be monitored M to carry the wireless tag 10 by, for example, a voice message via the speaker 14. Arousal guidance is provided (S14). Note that this guidance is repeated until the person to be monitored M carries the wireless tag 10. With this guidance, the monitored person M can reduce the situation in which he/she forgets to carry the wireless tag 10 at least when going out.

Despite this guidance, when the wireless tag 10 is not carried, the entrance/exit person detection unit 13 such as a human sensor placed at the entrance/exit DR of an entrance detects the movement of the person, and the person detection unit 12 If no movement of a person is detected for a predetermined period of time, it is determined that the person to be monitored M has gone out without carrying the wireless tag 10 (S15). Thereafter, the controller 20 notifies the management server 30 that the person to be monitored M has gone out without carrying a wireless tag (S16). The management server 30 identifies the person B related to the person to be monitored M who has received the notification (S17), and notifies the communication terminal 40 of the person B that the person to be monitored M has gone out without carrying a wireless tag. For example, the notification is sent by email (S18). As a result, the person concerned B can quickly learn of the fact that the person to be monitored M has gone out without carrying a wireless tag, and can take prompt action. For convenience of explanation, a case has been shown in which the person concerned B is notified that the person to be monitored M has gone out without carrying a wireless tag; however, the present invention is not limited to this, and the person to be monitored M If the person in possession of the communication terminal 40 is in possession of the communication terminal 40, the person to be monitored M himself may also be notified.

Note that the wireless tag detection unit 11 receives the above-mentioned BLE wireless signal, and the BLE wireless signal includes “TxPower” which is the transmission power of the wireless tag 10. By referring to this "TxPower" value, it is possible to measure RSSI (Received Signal Strength Indication), which is the received electric field strength. Since the received electric field strength attenuates in proportion to the square of the distance, the wireless tag detection unit 11 can estimate the distance to the wireless tag 10. The wireless tag detection unit 11 detects that the wireless tag 10 has moved when the change in the estimated distance is greater than or equal to a predetermined value.

For example, when the distance between the wireless tag detection unit 11 and the wireless tag 10 doubles, the received electric field strength decreases by 6 dB. Conversely, if the received field strength can be measured with an accuracy of 0.1 dB, a distance variation of about 1.5% of the distance between the wireless tag detection unit 11 and the wireless tag 10 can be detected.

The person detection unit 12 and the entrance/exit person detection unit 13 are, for example, human sensors that acquire infrared images and detect movement of people based on changes in the thermal images. However, instead of using infrared light, other techniques such as ultrasound can also be used.

<Configuration of tag mobile monitoring device>

Note that the wireless tag detection section 11, the person detection section 12, and the entrance/exit person detection section 13 may be communicatively connected to the controller 20 via a wireless relay device (not shown).

The storage unit 25 is a secondary storage medium such as a nonvolatile memory or a hard disk device, and stores monitored person information D1 and the like. The monitored person information D1 is data that links the identification information of the wireless tag 10 and the monitored person. This monitored person information D1 is referred to when the controller 20 notifies the management server 30 that the wireless tag 10 is not being carried when going out.

The control unit 26 is a control device that controls the entire controller 20, and includes a determination unit 26a, a guide unit 26b, and a notification processing unit 26c. In reality, the control unit 26 stores programs corresponding to these functional units in a storage device such as a nonvolatile memory, loads these programs into memory, and executes them on the CPU. This will cause the process to run.

The determination unit 26a determines that the monitored person M is not carrying the wireless tag 10 when the wireless tag detection unit 11 does not detect movement of the wireless tag 10 and the person detection unit 12 detects movement of a person. It is determined that Further, after determining that the person to be monitored M is not carrying the wireless tag 10, the determining unit 26a determines that the entrance/exit person detection unit 13 detects a person, and the person detection unit 12 detects movement of the person for a predetermined period of time. If not, it is determined that the person to be monitored M has gone out without carrying the wireless tag 10.

If the determining unit 26a determines that the person is not carrying the wireless tag 10, the guide unit 26b causes the person to be monitored M to perform audio guidance urging the person M to carry the wireless tag 10 via the speaker 23.

When the notification processing unit 26c determines that the monitored person M has gone out without carrying the wireless tag 10, the notification processing unit 26c performs a process of notifying the management server 30 to that effect.

Note that the wireless tag detection unit 11 receives a wireless signal from the wireless tag 10, and transmits information (for example, identification information and transmission power) indicated by the received wireless signal and/or the received electric field strength measured by the wireless tag detection unit 11 to the controller. 20, and the movement of the wireless tag 10 may be detected on the controller 20 side. In particular, when using a plurality of wireless tag detection units 11, which will be described later, movement of the wireless tag 10 is detected on the controller 20 side.

<Management server configuration>
FIG. 3 is a block diagram showing the configuration of the management server 30. As shown in FIG. 3, the management server 30 includes an input section 31, a display section 32, a communication section 33, a storage section 34, and a control section 35.

The storage unit 34 is a secondary storage medium such as a nonvolatile memory or a hard disk device, and stores related party information D2 and the like. The related person information D2 is data that links the person to be monitored M who carries the wireless tag 10 and the related person B, and includes the e-mail address of the related person B and the like. This related party information D2 is referenced when sending an e-mail of the notification contents to the communication terminal 40 of the related party B when the controller 20 sends a notification to the management server 30 that the wireless tag 10 is not being carried. .

The control unit 35 is a control device that controls the entire management server 30, and includes a notification processing unit 35a. In reality, the control unit 35 stores a program corresponding to this functional unit in a storage device such as a non-volatile memory, loads this program into memory, and executes it on the CPU to process the corresponding process. will be executed.

When the monitored person M receives a notification from the tag carrying monitoring device 1 that the monitored person M goes out without carrying the wireless tag 10, the notification processing unit 35a sends the monitored person M to the communication terminal 40 of the person B related to the monitored person M. sends a notification email to the effect that the person has gone out without carrying the wireless tag 10.

<Processing procedure for detecting non-carrying of wireless tag by controller>
Next, a procedure for detecting that the wireless tag 10 is not carried by the controller 20 will be described. FIG. 4 is a flowchart showing a processing procedure for detecting that the wireless tag 10 is not carried by the controller 20. As shown in FIG. 4, the wireless tag detection section 11 detects the movement of the wireless tag 10, and the person detection section 12 detects the movement of the person (step S110).

After that, the controller 20 determines whether the wireless tag 10 has moved within a certain period of time (step S120). If the wireless tag 10 moves within a certain period of time (step S120: No), the process moves to step S110, and then the determination process of step S120 is repeated.

On the other hand, if the wireless tag 10 has not moved within a certain period of time (step S120: Yes), then it is determined whether the wireless tag 10 has not moved and the movement of a person has been detected. (Step S130). If the wireless tag 10 does not move and movement of a person is not detected (step S130: No), the process moves to step S110.

If the wireless tag 10 does not move and the movement of the person is detected (step S130: Yes), the determination unit 26a determines that the person to be monitored M is not carrying the wireless tag 10 (step S140). . The guide unit 26b then issues a warning to the person to be monitored M to carry the wireless tag 10 (step S150).

Thereafter, a person is detected at the entrance/exit DR, and it is determined whether the person detection unit 12 is in a state in which no person is detected for a predetermined period of time (step S160). If a person is detected at the entrance/exit DR and the person detection unit 12 does not detect a person for a predetermined period of time (step S160: Yes), the notification processing unit 26c determines that the person to be monitored M is not carrying the wireless tag 10. The user notifies the management server 30 that he/she is out (step S170), and ends this process. On the other hand, if a person is detected at the entrance/exit DR and the person detection unit 12 detects the person within a predetermined period (step S160: No), this process ends. Note that the above process is repeatedly performed at predetermined time intervals.

<Notification process of going out without carrying a wireless tag>
FIG. 5 is a sequence diagram illustrating the procedure for notifying the user of leaving the house without carrying the wireless tag. As shown in FIG. 5, when the tag carrying monitoring device 1 detects that the wireless tag is not being carried while going out, it notifies the management server 30 that the wireless tag is not being carried while going out (step S210).

The management server 30, which has received the notification that the wireless tag is not carried, refers to the person concerned information D2 and identifies the person concerned B based on the person to be monitored information D1 of the person to be monitored M in the notification (step S220). Thereafter, an e-mail is sent to the communication terminal 40 of the identified party B to notify him/her that he/she is not carrying the wireless tag (step S230). Thereafter, the communication terminal 40 receives this email (step S240), and the person concerned B learns that the person to be monitored M has gone out without carrying the wireless tag 10.

In this embodiment, based on the movement detection of the wireless tag 10 by the wireless tag detection unit 11 and the movement detection of the person by the person detection unit 12, it is determined whether the person to be monitored M is not carrying a wireless tag, and Since a warning is provided to encourage the user to carry the wireless tag 10, it is possible to have the monitored person M carry the wireless tag 10 with a simple configuration, and to reduce the number of times the person goes out without carrying the wireless tag 10.

Furthermore, even if the monitored person M goes out without carrying the wireless tag 10, the person B related to the monitored person M can be promptly notified, so safety measures for the monitored person M can be quickly taken. Can be done.

<Modification 1>
In the above embodiment, one wireless tag detection unit 11 is used to detect whether or not the wireless tag 10 has moved based on a change in distance based on the received electric field strength. In the first modification, a plurality of wireless tag detection units 11 are used to improve the accuracy of detecting movement of the wireless tag 10.

FIG. 6 is an explanatory diagram illustrating movement detection of the wireless tag 10 according to the first modification. As shown in FIG. 6, this modification 1 includes two wireless tag detection sections 11a and 11b corresponding to the wireless tag detection section 11. Each of the wireless tag detection units 11a and 11b receives a wireless signal from the wireless tag 10, and measures the distance based on the received electric field strength.

In FIG. 6, the distances from the wireless tag 10 measured by the wireless tag detection units 11a and 11b are shown by equidistance lines. When the distance measured by the wireless tag detection section 11a is d1a and the distance measured by the wireless tag detection section 11b is d1b, it is possible to detect that the wireless tag 10 is present at the intersection position P1. Thereafter, if the distance measured by the wireless tag detection section 11a is d2a and the distance measured by the wireless tag detection section 11b is d2b, it is possible to detect that the wireless tag 10 is present at the intersection position P2. Therefore, when changing from position P1 to position P2, it is detected that the wireless tag 10 has moved. In this case, the distance traveled can also be determined on two-dimensional coordinates.

<Modification 2>
In the above embodiment, one wireless tag detection unit 11 is used to detect whether or not the wireless tag 10 has moved based on a change in distance based on the received electric field strength. In this second modification, the wireless tag detection unit 11 is provided with a scanning unit 41 that scans a directional antenna, and the movement of the wireless tag 10 is detected with high accuracy by determining the received electric field strength of the wireless signal from the scanned wireless tag 10. I try to do that.

FIG. 7 is an explanatory diagram illustrating movement detection of the wireless tag 10 according to the second modification. As shown in FIG. 7, the wireless tag detection section 11 includes a scanning section 41. The scanning unit 41 is equipped with a directional antenna, and the wireless tag detection unit 11 identifies the position of the wireless tag 10 based on the direction in which the received electric field strength is maximum during scanning and the distance determined from the maximum received electric field strength. For example, when the wireless tag 10 moves from position P1 to position P2, the wireless tag detection unit 11 detects the movement of the wireless tag 10.

Note that the scan range is preferably three-dimensional. Further, the scanning method may be mechanical scanning or electrical scanning.

<Modification 3>
By the way, the human detection unit 12 may also detect the motion of a person who does not move but only moves his/her limbs. , there is a possibility that the movement of the person is detected, but the movement of the wireless tag 10 is not detected. In this case, it is determined that the person to be monitored M is not carrying the wireless tag 10. Then, the guide section 26b continuously provides guidance to remind the user to carry the wireless tag 10.

Therefore, in the present modification example 3, when there is guidance from the guidance section 26b, a response section is provided that responds to the guidance to the effect that the monitored person M is carrying the wireless tag 10. . For example, as shown in FIG. 8, the wireless tag 10 is provided with a response button 10a as a response section. When the monitored person M presses the response button 10a, the wireless tag 10 transmits the response signal included in the BLE wireless signal. Upon receiving this response signal, the controller 20 determines that the wireless tag 10 is being carried by the person to be monitored M, and then stops continuous guidance by the guide section 26b for a certain period of time. This can prevent continuous guidance due to erroneous detection of non-carrying.

FIG. 9 is a flowchart showing a processing procedure for detecting that the wireless tag 10 is not carried when the response button 10a according to the third modification is used. As shown in FIG. 9, in this modified example 3, the processing of steps S180 and S190 is added to the processing of the embodiment shown in FIG. Note that the processing in steps S110 to S170 is the same as the processing shown in FIG.

In step S160 of FIG. 9, if a person is detected at the entrance/exit DR and no person is detected for a predetermined period (step S160: No), the controller 20 does not end this process and presses the response button 10a. It is determined whether there is a response to the press (step S180). If there is no response (step S180: No), this process ends.

On the other hand, if there is a response (step S180: Yes), it is further determined whether a certain period of time has passed since the response (step S190). If the fixed period has not elapsed (step S190: No), this determination process is repeated, and if the certain period has elapsed (step S190: Yes), this process ends. That is, if there is a response in the determination process of step S190, even if it is detected that the wireless tag 10 is not carried, the guidance process will not be performed for a certain period of time.

Note that the response section is not limited to the response button 10a, but may be a touch panel button provided on the wireless tag 10, for example. Further, the response section may be provided in the controller 20 or may be an independent response section. Furthermore, the response unit may have a voice recognition function and recognize a response message received by the microphone as a response. That is, a microphone is provided in addition to the speaker 23, and a voice recognition function for messages received by the microphone is provided on the controller 20 or on the cloud via the controller 20.

Incidentally, in the above embodiments and modified examples, an infrared human sensor is used as an example of the human detection unit 12, but the human detection unit 12 is not limited to this, and the human detection unit 12 uses a microphone array of an AI speaker to detect a person. Movement may also be detected. Since the microphone array can detect the direction and volume of audio, it can detect the movement (position) of a person. Since the AI speaker can ask questions to the person to be monitored M through the speaker, the position of the person can be detected more reliably through the discussion with the person to be monitored. Note that the AI speaker can perform voice authentication of the person to be monitored M by voice recognition, and can detect reliable movement of the person to be monitored M. Even if there are multiple people to be monitored in a room, the direction of movement can be determined for each person by calling out to each person and recognizing the speaker from the voice uttered by each person. can be tracked.

In addition, a trained model that outputs the probability that a person is moving is generated using machine learning such as deep learning, and sensor values such as a human sensor are input to this trained model, and the values are output from the trained model. It is also possible to improve accuracy by determining whether a person is moving or not based on probability (score). This is to exclude the fluctuation of curtains, movement of animals, etc. For example, when using deep learning, a large amount of teacher data consisting of sensor values such as a human sensor and correct answer data is prepared, and a multilayer neural network is caused to perform supervised learning using this teacher data. Sensor values such as a human sensor are input to the learned model generated in this way, and the probability (score) that a person is moving is output from the learned model.

Further, the wireless tag 10 is attached to the body such as the wrist, and may be equipped with a vital sensor that detects the body temperature, blood pressure, etc. of the person to be monitored M. The wireless tag 10 can manage the health of the monitored person M by including vital data detected by the vital sensor in a wireless signal and transmitting it.

Furthermore, the wireless tag 10 may be provided with an emergency button. When the monitored person M becomes unwell, by pressing the emergency button on the wireless tag 10 carried by the monitored person M, emergency information is included in a wireless signal and transmitted to the controller 20, and the network N is transmitted. The management server 30 or medical institution is notified via the notification. Thereby, emergency measures for the person to be monitored M can be taken quickly.

Note that when the wireless tag detection unit 11 measures the distance based on the received electric field strength, if the received electric field strength varies and is unstable, the average value of multiple received electric field strengths may be used.

In addition, when information such as emergency earthquake early warnings, tsunami information, special warnings, etc. announced by various government agencies such as the Japan Meteorological Agency, disaster information, evacuation information, etc. announced by local governments is distributed all at once by a telecommunications carrier via area mail. The controller 20 is configured to receive the area mail, increase the frequency of mobile monitoring of the wireless tag by the person to be monitored, and transmit this information from the controller 20 to the wireless tag so that it is displayed or output as audio on the wireless tag. You can also.

Furthermore, each configuration illustrated in the above embodiments is a functional schematic, and does not necessarily need to be physically configured as illustrated. In other words, the form of dispersion/integration of each device is not limited to the one shown in the diagram, but all or part of it can be functionally or physically distributed/integrated in arbitrary units depending on various loads and usage conditions. Can be configured.

The tag carrying monitoring device, the tag carrying monitoring system, and the tag carrying monitoring method according to the present invention are useful for issuing a warning to the monitored person to carry a wireless tag in a living room with a simple configuration.
