DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] DETAILED 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.

[0018] <Overview of the tag carrying monitoring system> An overview of a tag carrying monitoring system including a tag carrying monitoring device according to this embodiment will be described. 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 this embodiment. The tag carrying monitoring system 100 according to this embodiment is a system in which a wireless tag 10 is attached to a monitored person M who needs to be watched over and monitored, such as an elderly person, and the monitored person M's movement route when he or she goes out is monitored.

[0019] As a premise of the tag portable monitoring system 100, a wireless tag 10 transmits a wireless signal including its own tag identification information. Outdoors, a communication terminal 50 such as a smartphone having a receiving function and located near the wireless tag 10 or a fixed communication terminal 60 receives the wireless signal from the wireless tag 10.

[0020] The communication terminal 50 is, for example, a communication terminal carried by a passerby A. When the communication terminal 50 receives a wireless signal from the wireless tag 10, it 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 carried by a related person B of the monitored person M of the location information or movement line information of the monitored person M as necessary.

[0021] For fixedly placed communication terminals 60, management server 30 stores and manages the location information of communication terminals 60 in advance, and when communication terminals 60 receive radio waves from wireless tag 10, they transmit the identification information of wireless tag 10 and the identification number of communication terminal 60 itself to management server 30, and management server 30 reads out the stored location information of communication terminal 60 and notifies related party B of the location information or flow line information. In this way, in the case of fixedly placed communication terminals 60, location information is not transmitted each time because the location is fixed.

[0022] The wireless tag 10 is, for example, a low-power short-range wireless technology, such as Bluetooth (BLE) On the other hand, the communication terminal 50 and the fixed communication The communication terminal 50 has a function of receiving a BLE wireless signal. The communication terminal 50 also has a self-location measurement function such as a GPS.

[0023] 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 a monitored person M residing in a house H carries a wireless tag 10, and if not, provides a warning message encouraging the person to carry the wireless tag 10.

[0024] The tag carrying monitoring device 1 has a controller 20, to which a wireless tag detection unit 11, a human detection unit 12, and an entrance / exit human detection unit 13 are wirelessly connected. The wireless tag detection unit 11 is placed in a living space E of a house H, receives a wireless signal from a nearby wireless tag 10, estimates the distance to the wireless tag 10 based on the received electric field strength of the wireless signal, detects whether the wireless tag 10 has moved based on a change in this distance, and transmits a detection signal corresponding to the detection result to the controller 20 (S11). In addition, the human detection unit 12, such as a human sensor, detects whether a person in the living space E has moved, and transmits a detection signal corresponding to the detection result to the controller 20 (S12).

[0025] If the controller 20 does not detect the movement of the wireless tag 10 but detects the movement of a person, it determines that the monitored person M is not carrying the wireless tag 10 (S13). If the controller 20 determines that the monitored person M is not carrying the wireless tag 10, it issues a guidance to the monitored person M, for example, by a voice message via the speaker 14, to encourage the monitored person M to carry the wireless tag 10 (S14). This guidance is repeated until the monitored person M carries the wireless tag 10. This guidance can reduce the situation where the monitored person M forgets to carry the wireless tag 10, at least when going out.

[0026] Despite this notification, when the wireless tag 10 is not carried, if the entrance / exit human detection unit 13, such as a human sensor arranged at the entrance / exit DR, detects the movement of a person, and the human detection unit 12 does not detect the movement of a person for a predetermined period of time, it is determined that the monitored person M has gone out without carrying the wireless tag 10 (S15). After that, the controller 20 notifies the management server 30 that the monitored person M has gone out without carrying the wireless tag (S16). The management server 30 identifies the related person B of the monitored person M who received the notification (S17), and notifies the communication terminal 40 of the related person B, for example, by email, that the monitored person M has gone out without carrying the wireless tag (S18). This allows the related person B to quickly know the fact that the monitored person M has gone out without carrying the wireless tag, and to quickly deal with the situation. For ease of explanation, we have shown a case in which the relevant person B is notified that the monitored person M has gone out without carrying a wireless tag, but the present invention is not limited to this, and if the monitored person M is carrying a communication terminal 40, the monitored person M himself may also be notified.

[0027] The wireless tag detection unit 11 receives the above-mentioned BLE wireless signal, which includes "TxPower" that is the transmission power of the wireless tag 10. By referring to the value of this "TxPower", 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 equal to or greater than a predetermined value.

[0028] For example, when the distance between the wireless tag detection unit 11 and the wireless tag 10 is doubled, the received electric field strength drops by 6 dB. Conversely, if the received electric 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.

[0029] The human detection unit 12 and the entrance / exit human detection unit 13 are, for example, human sensors that acquire infrared images and detect human movement based on changes in the thermal images. However, instead of using infrared rays, other technologies such as ultrasonic waves can also be used.

[0030] <Configuration of the tag portable monitoring device> Next, the configuration of the tag carrying monitoring device 1 will be described. Fig. 2 is a block diagram showing the configuration of the tag carrying monitoring device 1. As shown in Fig. 2, the tag carrying monitoring device 1 has a wireless tag 10, a wireless tag detection unit 11, a human detection unit 12, an entrance / exit human detection unit 13, and a controller 20. Each of these units has already been described, so their description will be omitted here. In addition, the controller 20 has an input unit 21, a display unit 22, a speaker 23, a communication unit 24, a memory unit 25, and a control unit 26.

[0031] The input unit 21 is an input device such as a keyboard or a mouse, and the display unit 22 is a display device such as a liquid crystal panel or a display device. The speaker 23 is an output device that issues voice guidance to the monitored person M to alert him / her to carry the wireless tag 10. The communication unit 24 is a communication device for communicating with various devices such as the wireless tag detection unit 11, the human detection unit 12, the entrance / exit human detection unit 13, and the management server 30 via the network N. The wireless tag detection unit 11, the human detection unit 12, and the entrance / exit human detection unit 13 may be communicatively connected to the controller 20 via a wireless relay device (not shown).

[0032] The storage unit 25 is a secondary storage medium such as a non-volatile memory or a hard disk drive, and stores monitored person information D1, etc. The monitored person information D1 is data linking the identification information of the wireless tag 10 with the monitored person. This monitored person information D1 is referenced when the controller 20 notifies the management server 30 that the wireless tag 10 has gone out without being carried.

[0033] The control unit 26 is a control device that controls the entire controller 20, and includes a determination unit 26a, a guidance unit 26b, and a notification processing unit 26c. In practice, the control unit 26 stores programs corresponding to these functional units in a storage device such as a non-volatile memory, and loads these programs into the memory and executes them on the CPU, thereby executing the corresponding processes.

[0034] When the wireless tag detection unit 11 does not detect the movement of the wireless tag 10 and the human detection unit 12 detects the movement of a person, the determination unit 26a determines that the monitored person M is not carrying the wireless tag 10. Furthermore, when the entrance / exit human detection unit 13 detects a person and the human detection unit 12 does not detect the movement of a person for a predetermined period after determining that the monitored person M is not carrying the wireless tag 10, the determination unit 26a determines that the monitored person M has gone out without carrying the wireless tag 10.

[0035] When the determining unit 26a determines that the wireless tag 10 is not being carried, the guiding unit 26b causes the speaker 23 to provide audio guidance encouraging the monitored person M to carry the wireless tag 10.

[0036] When it is determined that the monitored person M has gone out without carrying the wireless tag 10, the notification processing unit 26c performs processing to notify the management server 30 of that fact.

[0037] The wireless tag detection unit 11 may receive a wireless signal from the wireless tag 10 and transmit information indicated by the received wireless signal (e.g., identification information and transmission power) 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 a plurality of wireless tag detection units 11, which will be described later, are used, the movement of the wireless tag 10 is detected on the controller 20 side.

[0038] <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 unit 31, a display unit 32, a communication unit 33, a storage unit 34, and a control unit 35.

[0039] The input unit 31 is an input device such as a keyboard or a mouse, and the display unit 32 is a display device such as a liquid crystal panel or a display device. The communication unit 33 is a communication device for communicating with various devices such as the tag carrying monitoring device 1 and the communication terminals 40 and 50 via the network N.

[0040] The storage unit 34 is a secondary storage medium such as a non-volatile memory or a hard disk drive, and stores related person information D2, etc. The related person information D2 is data linking the monitored person M who carries the wireless tag 10 with the related person B, and includes the email address of the related person B, etc. When the controller 20 notifies the management server 30 that the monitored person M has gone out without carrying the wireless tag 10, the related person information D2 is referenced when sending the notification content to the communication terminal 40 of the related person B by email.

[0041] The control unit 35 is a control device that controls the entire management server 30, and has a notification processing unit 35a. In practice, the control unit 35 stores a program corresponding to this functional unit in a storage device such as a non-volatile memory, and loads this program into memory and executes it on the CPU, thereby executing the corresponding process.

[0042] When the notification processing unit 35a receives a notification from the tag carrying monitoring device 1 that the monitored person M has gone out without carrying the wireless tag 10, it sends a notification email to the communication terminal 40 of a related person B of the monitored person M to inform them that the monitored person M has gone out without carrying the wireless tag 10.

[0043] <Processing procedure for detecting non-carrying of wireless tags by the controller> Next, a description will be given of the procedure for detecting non-carrying of the wireless tag 10 by the controller 20. Fig. 4 is a flowchart showing the procedure for detecting non-carrying of the wireless tag 10 by the controller 20. As shown in Fig. 4, the wireless tag detection unit 11 detects the movement of the wireless tag 10, and the human detection unit 12 detects the movement of a person (step S110).

[0044] After that, the controller 20 judges whether the wireless tag 10 has moved within a certain time (step S120). If the wireless tag 10 has moved within the certain time (step S120: No), the controller 20 proceeds to step S110, and then repeats the judgment process of step S120.

[0045] On the other hand, if the wireless tag 10 has not moved within the certain period of time (step S120: Yes), it is then determined whether the wireless tag 10 has not moved and whether a person's movement has been detected (step S130). If the wireless tag 10 has not moved and a person's movement has not been detected (step S130: No), the process proceeds to step S110.

[0046] If the wireless tag 10 does not move and movement of a person is detected (step S130: Yes), the determination unit 26a determines that the monitored person M does not carry the wireless tag 10 (step S140). Then, the guidance unit 26b provides a warning to the monitored person M to encourage him or her to carry the wireless tag 10 (step S150).

[0047] Thereafter, it is determined whether a person is detected at the entrance / exit DR and the human detection unit 12 has not detected a person for a predetermined period of time (step S160). If a person is detected at the entrance / exit DR and the human detection unit 12 has not detected a person for a predetermined period of time (step S160: Yes), the notification processing unit 26c notifies the management server 30 that the monitored person M has gone out without carrying the wireless tag 10 (step S170) and ends this process. On the other hand, if a person is detected at the entrance / exit DR and the human detection unit 12 has detected a person within the predetermined period of time (step S160: No), this process ends. The above process is repeated at predetermined time intervals.

[0048] <Notification process for when you go out without carrying a radio tag> 5 is a sequence diagram showing a notification process procedure for notifying the user that a wireless tag has not been carried. As shown in FIG. 5, when the tag carrying monitoring device 1 detects that a user has gone out without carrying a wireless tag, the tag carrying monitoring device 1 notifies the management server 30 that a user has gone out without carrying a wireless tag (step S210).

[0049] The management server 30, which has received the notification that the person being monitored has gone out without carrying a wireless tag, refers to the person involved information D2 and identifies the person involved B based on the monitored person information D1 of the monitored person M in the notification (step S220). Then, an email notifying the identified person involved B of the going out without carrying a wireless tag is sent to the communication terminal 40 of the person involved B (step S230). Then, the communication terminal 40 receives this email (step S240), and the person involved B learns that the monitored person M has gone out without carrying a wireless tag 10.

[0050] In this embodiment, it is determined whether the monitored person M is not carrying a wireless tag based on the detection of movement of the wireless tag 10 by the wireless tag detection unit 11 and the detection of human movement by the human detection unit 12, and a warning message is provided to the monitored person M to encourage him or her to carry the wireless tag 10.Therefore, with a simple configuration, it is possible to have the monitored person M carry the wireless tag 10 and reduce the number of times that he or she goes out without carrying the wireless tag 10.

[0051] In addition, even if the monitored person M goes out without carrying the wireless tag 10, the person concerned B of the monitored person M can be quickly notified, so that safety measures for the monitored person M can be taken quickly.

[0052] <Variation 1> In the above embodiment, one wireless tag detection unit 11 is used to detect whether the wireless tag 10 has moved based on a change in distance based on the received electric field strength. In the present modified example 1, multiple wireless tag detection units 11 are used to improve the accuracy of detecting the movement of the wireless tag 10.

[0053] Fig. 6 is an explanatory diagram for explaining detection of movement of the wireless tag 10 according to the present modified example 1. As shown in Fig. 6, the present modified example 1 has two wireless tag detection units 11a and 11b corresponding to the wireless tag detection unit 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.

[0054] In Fig. 6, the distances to the wireless tag 10 measured by the wireless tag detection units 11a and 11b are shown by equal distance lines. When the distance measured by the wireless tag detection unit 11a is d1a and the distance measured by the wireless tag detection unit 11b is d1b, it can be detected that the wireless tag 10 exists at the position P1 of the intersection. Thereafter, when the distance measured by the wireless tag detection unit 11a is d2a and the distance measured by the wireless tag detection unit 11b is d2b, it can be detected that the wireless tag 10 exists at the position P2 of the intersection. Therefore, when the position changes from P1 to P2, it is detected that the wireless tag 10 has moved. In this case, the distance that has moved can also be found on a two-dimensional coordinate system.

[0055] <Variation 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 the present modified example 2, a scanning unit 41 that scans a directional antenna is provided in the wireless tag detection unit 11, and the received electric field strength of the wireless signal from the scanned wireless tag 10 is obtained to accurately detect the movement of the wireless tag 10.

[0056] Fig. 7 is an explanatory diagram for explaining detection of movement of the wireless tag 10 according to the present modified example 2. As shown in Fig. 7, the wireless tag detection unit 11 has a scanning unit 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 calculated from the maximum received electric field strength. For example, when the position P1 of the wireless tag 10 moves to a position P2, the wireless tag detection unit 11 detects the movement of the wireless tag 10.

[0057] The scanning range is preferably three-dimensional. The scanning method may be mechanical scanning or electrical scanning.

[0058] <Variation 3> Incidentally, since the human detection unit 12 may detect movements such as the movement of the limbs of a person without moving, when the monitored person M carrying the wireless tag 10 does not move significantly but only moves his / her body, there is a possibility that the human movement will be detected but the movement of the wireless tag 10 will not be detected. In this case, it is determined that the monitored person M is not carrying the wireless tag 10. The guidance unit 26b will then continuously provide guidance to call attention to the carrying of the wireless tag 10.

[0059] Therefore, in the present third modification, when guidance is given by the guidance unit 26b, a response unit is provided that responds to this guidance by the monitored person M that the wireless tag 10 is being carried. For example, as shown in FIG. 8, a response button 10a is provided as the response unit in the wireless tag 10. When the monitored person M presses the response button 10a, the wireless tag 10 transmits a response signal by including it in a BLE wireless signal. Upon receiving this response signal, the controller 20 determines that the wireless tag 10 is being carried by the monitored person M, and thereafter stops continuous guidance by the guidance unit 26b for a certain period of time. This makes it possible to prevent continuous guidance due to erroneous detection that the tag is not being carried.

[0060] Fig. 9 is a flowchart showing the procedure of the non-carrying detection process for the wireless tag 10 when the response button 10a according to the modified example 3 is used. As shown in Fig. 9, in the modified example 3, the processes of steps S180 and S190 are added to the process of the embodiment shown in Fig. 4. The processes of steps S110 to S170 are the same as those shown in Fig. 4.

[0061] 9, if a person is detected at the entrance / exit DR and the state is not one in which no person has been detected for a predetermined period of time (step S160: No), the controller 20 does not end this process, but determines whether or not there has been a response by pressing the response button 10a (step S180). If there is no response (step S180: No), this process ends.

[0062] On the other hand, if there is a response (step S180: Yes), it is further determined whether or not a certain period of time has passed since the response (step S190). If the certain period of time has not passed (step S190: No), this determination process is repeated, and if the certain period of time has passed (step S190: Yes), this process is terminated. In other words, if there is a response by the determination process of step S190, even if it is detected that the wireless tag 10 is not being carried, the guidance process is not performed for a certain period of time.

[0063] The response unit is not limited to the response button 10a, and may be, for example, a touch panel button provided on the wireless tag 10. The response unit may be provided in the controller 20, or may be an independent response unit. Furthermore, the response unit may have a voice recognition function and recognize a response message received by a microphone as a response. That is, a microphone is provided in addition to the speaker 23, and a voice recognition function for a message received by the microphone is provided on the controller 20 or on a cloud via the controller 20.

[0064] In the above embodiment and modified example, an infrared human sensor is used as an example of the human detection unit 12, but the human detection unit 12 may detect the movement of a person using a microphone array of an AI speaker. The microphone array can detect the direction and volume of a voice, so that the movement (position) of a person can be detected. The AI ​​speaker can ask questions to the monitored person M through the speaker, so that the position of a person can be detected more reliably by a question and answer session with the monitored person. The AI ​​speaker can perform voice authentication of the monitored person M through voice recognition, so that the movement of the monitored person M can be detected reliably. Even if there are multiple monitored people in a room, the movement direction of each monitored person can be tracked by calling each monitored person and performing speaker recognition from the voices uttered by each monitored person.

[0065] In addition, a trained model that outputs the probability that a person is moving can be generated by machine learning such as deep learning, and sensor values ​​such as a human presence sensor can be input to this trained model to determine whether a person is moving or not based on the probability (score) output from the trained model, thereby improving accuracy. This is to exclude swaying curtains, animal movement, etc. For example, when using deep learning, a large amount of teacher data consisting of sensor values ​​such as a human presence sensor and correct answer data is prepared, and the multilayer neural network is made to perform supervised learning using this teacher data. Sensor values ​​such as a human presence sensor are input to the trained model generated in this way, and the trained model outputs the probability (score) that a person is moving.

[0066] 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, and the like of the monitored person M. The wireless tag 10 can manage the health of the monitored person M by transmitting vital data detected by the vital sensor in a wireless signal.

[0067] Furthermore, an emergency button may be provided on the wireless tag 10. When the monitored person M becomes ill, the monitored person M presses the emergency button on the wireless tag 10 carried by the monitored person M, and emergency information is transmitted in a wireless signal to the controller 20, which is then notified to the management server 30 or a medical institution via the network N. This allows emergency measures to be promptly taken for the monitored person M.

[0068] 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 the received electric field strength measured multiple times may be used.

[0069] In addition, when information such as emergency earthquake alerts, tsunami information, and special warnings issued by various government agencies such as the Japan Meteorological Agency, and disaster information and evacuation information issued by local governments are distributed simultaneously by telecommunications carriers via area mail, the controller 20 can receive the area mail and increase the frequency with which the monitored person carries and monitors the wireless tag, and can also be configured to transmit this information from the controller 20 to the wireless tag and display or output it as audio on the wireless tag.

[0070] In addition, each configuration illustrated in the above embodiment is merely a functional schematic, and does not necessarily have to be physically configured as illustrated. In other words, the form of distribution and integration of each device is not limited to that illustrated, and all or part of the devices can be functionally or physically distributed and integrated in any unit according to various loads, usage conditions, etc. [Industrial Applicability]
