Description

  The present invention relates to an outing monitoring system for monitoring the outing of the transmission source of a radio wave by a transmitted radio wave.

  A system has been proposed in which a sensor that detects the state of the body is attached to a protected person such as an elderly person, and the detection result of the sensor is periodically transmitted to the home server using the electric energy generated by the power generation unit. (For example, see Patent Document 1).

  Certainly, it is important to understand the physical condition of the person to be protected, especially when there is physical anxiety, but if there is a cranial nerve anxiety such as dementia, the behavior of the person to be protected is understood. It becomes important to do.

  Therefore, the protected person who is indoors keeps the transmitter, and the communication terminal owned by the guardian who is indoors and the transmitter held by the protected person always communicate, and the protected person A system has been developed in which when the intensity of the radio wave from the transmitter falls below a threshold value, it is assumed that the guardian who should be indoors is away from the guardian by a predetermined distance, that is, has gone out. In addition, when receiving radio waves from a protected person's transmitter on a third party's mobile terminal, etc. outdoors, a system that notifies the position information of the recipient to the server and grasps the position of the protected person Have also been developed (see, for example, Patent Documents 2 and 3).

JP 2004-220539 A JP 2002-271835 A Japanese Patent Laying-Open No. 2015-022751

  However, in order to always transmit from the transmitter of the person to be protected, the power source of the transmitter must be always turned on, and a battery is used as the power source of the transmitter. Even if the battery used here is a primary battery or a secondary battery, it is charged from a commercial power source. If the primary battery needs to be replaced or charged from a commercial power source, or if the battery runs out, Even if the protected person is indoors, it is considered that he / she has gone out, or the position of the protected person cannot be grasped outdoors.

  The above explanation has been given by taking as an example a person who has cranial nerve anxiety as a person to be protected, but even an infant may go out alone. Furthermore, pets such as dogs and cats may steal their eyes and go out. As described above, there are various targets as the monitoring target for going out.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide an outing monitoring system that monitors outing without worrying about battery exhaustion, replacement of a primary battery, or charging from a commercial power source.

The outing monitoring system of the present invention that solves the above-mentioned object is
A power generation unit;
A transmission unit that transmits radio waves using electrical energy generated by the power generation unit;
A receiving unit installed at an entrance and receiving a radio wave from the transmitting unit;
The at least one notification execution condition for executing notification that the radio wave received by the receiving unit is equal to or higher than a threshold value, and a notification unit for executing the notification when the notification execution condition is satisfied It is characterized by having.

  According to the outing monitoring system of the present invention, a power generation unit is used as a power source, and radio waves are transmitted using electric energy generated by the power generation unit. There is no need to charge from the power supply. In addition, since the notification unit executes the notification based on one of the notification execution conditions that the radio wave intensity is equal to or higher than a threshold value, the transmission unit does not need to constantly transmit radio waves, and the power generation unit generates power. What is necessary is just to transmit a radio wave when it comes to be able to transmit a radio wave with the made electric energy, and the structure which combined the said electric power generation part and the said transmission part functions as a sensor. And when the said sensor passes the entrance / exit in which the said receiving part was installed, the electromagnetic wave received by the said receiving part will become the radio field intensity more than a threshold value, and the said alerting | reporting will be performed by the said alerting | reporting part. In this way, the outing monitoring system of the present invention can accurately monitor the outing by detecting that the sensor passes through the entrance / exit, and by the radio wave transmitted from a place away from the entrance / exit. It is possible to reduce false detection that the notification is executed.

  In addition, the said receiving part and the said alerting | reporting part may be separate, and may be integral. In the case of separate bodies, communication may be performed between the reception unit and the notification unit, and both may be located apart from each other.

  In addition, since the notification unit is installed in a room where a guardian or the like is indoors, the notification directly reaches the room where the guardian or the like is present.

  Further, the notification unit may perform notification by light, may perform notification by vibration (vibration), or may perform notification by sound. In addition, notification by display using a display device such as a liquid crystal display device may be executed.

  Further, the power generation unit may be of an electromagnetic induction type that generates power by vibration, may be of an electrostatic type, or converts an applied force into a voltage, that is, It may be one that generates electric power when pressure is applied, or one that generates electric power upon receiving an impact (for example, a piezoelectric element).

  Further, the transmission unit transmits radio waves when it can transmit radio waves by the electric energy generated by the power generation unit, and does not transmit radio waves unless generated by the power generation unit. is there.

  Moreover, the aspect provided with the electrical storage part which accumulate | stores the electrical energy produced | generated by the said electric power generation part may be sufficient. Examples of the power storage unit include a lithium ion capacitor and a lithium ion secondary battery.

In the monitoring system of the present invention,
The aspect characterized by the said power generation part and the said transmission part being provided in footwear may be sufficient.

  According to this aspect, the power generation unit and the transmission unit do not normally get in the way of the person to be protected, and the power generation unit generates power when walking with the footwear on, and when going out with the footwear on. Radio waves are transmitted. For this reason, when it is going to go out by putting on footwear, that is, when it is necessary, the electric power is generated and the radio wave is transmitted, and it is not necessary for the protected person to keep the power generation unit and the transmission unit. Also, the power generation part and the transmission part are provided in footwear (outdoor footwear) that has the habit of wearing outdoors, that is, the habit of wearing when going out, so that the doorway passes through the entrance / exit even though it is indoors. Can be greatly reduced.

The footwear includes a sensor that detects a change that occurs when the footwear is worn,
The transmission unit also transmits detection information indicating that the sensor has detected the change using electric energy generated by the power generation unit,
The receiving unit also receives the detection information,
The notification unit may execute the notification as one of the notification execution conditions that the reception unit receives the detection information.

  In this way, even if a guardian or a third party moves the footwear by cleaning or the like, even if power is generated by the power generation unit, it can be prevented from being detected as going out. Can do.

  The sensor may be, for example, a pressure sensor that detects a change in pressure that occurs when the sensor is worn, or a temperature sensor that detects a human body temperature. Moreover, if the sensor is a pressure sensor, it is preferable from the viewpoint of detection accuracy and the like that it is attached to the heel portion of the footwear. Further, the sensor may detect the change by electric energy generated by the power generation unit.

And a plurality of the transmission units.
Each of the plurality of transmitting units transmits unique identification information to the receiving unit,
The receiving unit is to identify and receive from which of the plurality of transmitting units the radio wave,
The notification unit may execute the notification for each of the plurality of transmission units.

In the monitoring system of the present invention,
The transmitter is separate from the transmitter, and includes a second transmitter that transmits the second radio wave,
The transmitting unit transmits the first radio wave;
That the notification unit receives the second radio wave received from the second transmission unit with a radio field intensity less than a second threshold is one of the notification execution conditions when the notification execution condition is satisfied. Even if the first radio wave has a radio field intensity greater than or equal to the threshold value, the notification is not performed if the second radio wave also has a radio field intensity greater than or equal to the second threshold value. The aspect characterized by this may be sufficient.

  According to this aspect, for example, when the guardian who possesses the transmission unit and the guardian who possesses the second transmission unit pass through the doorway together, the notification is not executed. From the viewpoint of the guardian, he / she knows that the guardian is going out because he / she is attending, and the notification is unnecessary. In this aspect, it is possible to reduce the execution of such extra notification.

  Note that the radio wave intensity less than the second threshold includes that the second radio wave is not transmitted (the radio wave intensity is 0).

  Further, the threshold value and the second threshold value may be the same value threshold value or different value threshold values.

In the monitoring system of the present invention,
An external communication terminal that exists outside the doorway and can receive radio waves from the transmitter;
Including a server capable of communicating with the external communication terminal;
When the external communication terminal receives a radio wave from the transmission unit, the external communication terminal transmits position information indicating a position of the external communication terminal when the radio wave is received to the server. It is also possible to use this mode.

  Even after the protected person possessing the power generation unit and the transmitting unit has gone out, the protected person can be searched for by accessing the server.

  The position information may include information representing time, but the server may store the time when the position information is received together with the position information.

In the monitoring system of the present invention,
A terminal different from the external communication terminal, including an internal communication terminal capable of communicating with the server;
When the position information is transmitted, the server may transmit discovery information indicating that the position information has been transmitted to the internal communication terminal.

  The internal communication terminal is owned by the guardian, and even after the protected person has gone out, the discovery information is transmitted to the internal communication terminal. The search for the protected person can be performed by accessing the server from the internal communication terminal.

  The discovery information may include the location information, or may simply indicate that the server has received the location information.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a diagram showing footwear constituting a part of the outing monitoring system of the present invention.

  A footwear 10 shown in FIG. 1 is a shoe having a footwear base 11 and an upper 19. A power generation unit 15 and a wireless transmission unit 16 are provided on the inner side of the outsole 111 in the footwear 11 and serving as the heel portion 13. The power generation unit 15 is of an electromagnetic induction type that generates power by vibrating. That is, the power generation unit 15 is provided with a power generation unit 151 (see FIG. 3B), which is not illustrated, but the power generation unit includes a fixedly arranged conductive coil and a swing with respect to the conductive coil. And a magnetic circuit unit arranged movably. When vibration is applied to the power generation unit, the magnetic circuit unit swings with respect to the conductive coil, so that an induced electromotive force is generated in the conductive coil and electric energy is obtained. Therefore, when walking with the footwear 10, electric energy is obtained by the power generation unit 151. The power generation unit may be of an electrostatic type, or converts an applied force into a voltage, that is, generates power when pressure is applied or generates power upon receiving an impact (for example, , A piezoelectric element). However, the electromagnetic induction method tends to obtain a large amount of power generation compared to other methods, and is suitable for transmission.

  The wireless transmission unit 16 transmits radio waves using the electrical energy generated by the power generation unit, and does not have a reception function. The wireless communication here may be a wireless LAN, but the communication in accordance with the communication standard of Bluetooth (registered trademark) Low Energy (BLE) is compared with the low power consumption and the radio wave reach distance of several tens of meters. It is preferable because it is long. Each time a person wearing the footwear 10 walks, the radio transmission unit 16 transmits radio waves according to the BLE communication standard. The wireless transmission unit 16 corresponds to an example of a transmission unit referred to in the present invention.

  A pressure sensor 14 is built in the top plate 112 of the footwear base 11. The pressure sensor 14 is a sensor that detects the pressure that is stepped on with the heel when the footwear 10 is put on, and is driven using electrical energy generated by the power generation unit. The pressure sensor 14 and the button battery may be built in a replaceable insole or the like, and the pressure sensor 14 may be driven by the button battery. The pressure sensor 14 outputs a detection signal when detecting the pressure. The wireless transmission unit 16 also transmits detection information indicating that a detection signal is output from the pressure sensor 14 using the electric energy generated by the power generation unit. The power generation unit generates power when the footwear 10 is worn and walked, and also generates power when the footwear 10 is lifted or moved during cleaning. In the outing monitoring system of the present invention, it is expected that radio waves are transmitted from the wireless transmission unit 16 only when a protected person such as an elderly person walks while wearing the footwear 10, but actually, cleaning is performed. There are scenes where vibration is applied to the footwear 10 in various living environments. For this reason, although mentioned later for details, it is determined using the said detection information whether it is an electromagnetic wave emitted when walking with the footwear 10 on. The sensor is not limited to the pressure sensor, and any sensor that can detect a change that occurs when the footwear 10 is worn may be used. For example, a temperature sensor that detects the body temperature of a person wearing the footwear may be used. Further, these sensors are not necessarily essential constituent elements and can be omitted.

  Further, the power generation unit 15 and the wireless transmission unit 16 do not necessarily need to be built in the heel portion 13, and may be built in, for example, the toe portion. The footwear is not limited to shoes, and may be sandals or clogs.

  Further, although the power generation unit 15 and the wireless transmission unit 16 are incorporated in the footwear 10 here, the power generation unit 15 and the wireless transmission unit 16 may be incorporated in the buckle of the belt, or a dedicated type case attached to the belt. Alternatively, the power generation unit 15 and the wireless transmission unit 16 may be incorporated in a dedicated type case that is worn on the neck. Or even if it is a shoebox door installed at the entrance of the entrance, etc., the power generation unit can generate power by vibration when opening and closing when taking out footwear, so a power generation unit is provided on the door of the shoebox Also good. Further, the power generation unit may be provided on a door of an entrance / exit or a member that is provided indoors and that must be opened and closed or moved when the user goes out. That is, a power generation unit may be provided in an object that generates vibration when triggered by going out.

  FIG. 2 is a diagram showing a receiver and a notification terminal that constitute a part of the outing monitoring system of the present invention.

  The receiver 20 shown in FIG. 2 is installed at an indoor entrance such as a facility or home, and transmits a notification signal. FIG. 2 shows two types of notification terminals 31 and 32. One of the two types of notification terminals is a wristwatch type notification terminal 31 and includes a main body 311 and a band member 312 that is wound around the wrist. The other is a strap-type notification terminal 32, and the main body 321 is provided with a through hole 3210 for passing a strap (not shown). Both types of notification terminals 31 and 32 have a built-in secondary battery that is charged using a commercial power source. In addition, ring-shaped light emitting units 3111 and 3211 are provided on the surfaces of the main bodies 311 and 321, and a vibration function is mounted inside the main bodies 311 and 321. The light emitting units 3111 and 3211 are made of light emitting diodes. When a notification signal is received from the receiver 20, the light emitting units 3111 and 3211 emit light for a predetermined time by supplying power from the secondary battery. In addition, the vibration function also vibrates for a predetermined time by receiving power from the secondary battery when receiving a notification signal from the receiver 20. The light emission of the light emitting units 3111 and 3211 and the vibration caused by the vibration function correspond to an example of the notification referred to in the present invention. Cancel buttons 3112 and 3212 are provided inside the ring-shaped light emitting units 3111 and 3211. When the cancel buttons 3112 and 3212 are pressed during notification, the light emitting units 3111 and 3211 are turned off, and a vibration function is provided. Will stop and the notification will end.

  The front panel 21 of the receiver 20 is provided with a power switch 211, a first light emitting unit 2121 to a fourth light emitting unit 2124, a start button 213, a stop button 214, and a test button 215. The receiver 20 is driven by a commercial power source and is turned on / off by a power switch 211. Charging units 221 and 222 for charging secondary batteries built in the notification terminals 31 and 32 are provided on the upper surface 22 of the receiver 20.

  The receiver 20 receives radio waves transmitted from the wireless transmission unit 16 shown in FIG. The receiver 20 can identify radio waves transmitted from four different wireless transmission units 16, and includes four wireless transmission units 16, four light emitting units such as a first light emitting unit 2121 to a fourth light emitting unit 2124. Are registered in a one-to-one correspondence, and when a notification execution condition described later is satisfied, the corresponding light emitting unit among the first light emitting unit 2121 to the fourth light emitting unit 2124 emits light. The light emitted from the light emitting unit also corresponds to an example of notification according to the present invention. That is, in the present embodiment, the notification is also executed by the receiver 20 itself. Note that the notification (light emission) in the first light emitting unit 2121 to the fourth light emitting unit 2124 of the receiver 20 can be stopped by pressing the stop button 214.

  Radio communication is also performed between the receiver 20 and the notification terminals 31 and 32. This wireless communication is also communication according to the BLE communication standard. Although the receiver 20 is a receiver, the receiver 20 includes a transmission / reception unit 201 (see FIG. 3B), and can perform transmission / reception in accordance with the BLE communication standard. In the BLE communication standard, pairing can be executed when transmission / reception is possible, and the receiver 20 can register four notification terminals 31 and 32 by pairing. When the start button 213 is pressed, the receiver 20 enters an outing monitoring state, and any one of the four wireless transmission units 16 from when the start button 213 is pressed until the stop button 214 is pressed. When the radio wave from 16 satisfies a notification execution condition described later, the transmission / reception unit 201 of the receiver 20 transmits a notification signal to all four notification terminals 31 and 32 all at once. The four wireless transmission units 16 and the four notification terminals 31 and 32 are registered in a one-to-one correspondence, and the wireless transmission unit 16 that satisfies the notification execution condition among the four wireless transmission units 16. The notification signal may be transmitted only to the notification terminal corresponding to the above.

  When the test button 215 is pressed, the test mode is entered and all of the first light emitting unit 2121 to the fourth light emitting unit 2124 emit light for a predetermined time even if the notification execution condition is not satisfied. The 32 light emitting units 3111 and 3211 also emit light for a predetermined time, and vibration due to the vibration function also occurs for a predetermined time. By this test mode, the guardian can confirm that the notification is executed without any problem.

  FIG. 3A is a diagram showing a first embodiment in which the outing monitoring system of the present invention is applied to a system for monitoring the outing of an elderly person with cranial nerve anxiety such as dementia. ) Is a block diagram of the outing monitoring system 1 shown in FIG. In FIG. 3A, an elderly person who is a guardian is represented by “old”, and a guardian is represented by “maintenance” (the same applies hereinafter).

  FIG. 3A shows a building B such as a nursing facility or a home, and the outing monitoring system 1 of the first embodiment is arranged in the building B. That is, the receiver 20 shown in FIG. 2 is installed in the vicinity of an entrance / exit such as an entrance. Further, the guardian is in the building B with the notification terminal 31 shown in FIG. Further, FIG. 3A also shows the footwear 10 shown in FIG. 1, and the letters “Old” are shown in the figure of the footwear 10. This represents that an elderly person who is a guardian wears the footwear 10 (the same applies to the following). In FIG. 3A, an elderly person wearing the footwear 10 is in the vicinity of the doorway.

  It has been reported that even elderly people who have cranial nervous anxiety such as dementia often go out with footwear, not barefoot, when going out. In a nursing facility, an elderly person takes his / her footwear to his / her own room, and when he / she goes out, he / she takes his / her footwear from his / her room and wears the footwear at the entrance / exit of the entrance or the like to go out. The inventor pays attention to these points and invented a system for monitoring the going out of a person using footwear. In addition, since the power generation unit 15 and the wireless transmission unit 16 are built in the footwear 10, the power generation unit 151 does not normally interfere with the person to be protected because these units 15 and 16 are walking while wearing the footwear 10. Generates electric power, and radio waves are transmitted when the user wears the footwear 10 and goes out. For this reason, when the user wants to go out with the footwear 10, that is, when necessary, the electric power is generated and the radio wave is transmitted, and it is not necessary for the guardian to always carry the power generation unit 15 and the wireless transmission unit 16. In addition, by installing these units 15 and 16 on footwear (outdoor footwear) that has the habit of wearing outdoors, that is, the habit of wearing when going out, it is falsely detected that the vehicle has passed the entrance / exit even though it is indoors. Can be greatly reduced. Note that the footwear 10 may be a unique one with a fixed owner or a common one. In the case of shared footwear, you don't know who went out, but you can at least know that someone has gone out and can search even if the outsider is unknown.

  In FIG. 3B, the power generation unit 15 of the footwear 10 shown in FIG. 1 is also shown in detail in a block diagram. The power generation unit 15 also includes a rectification unit 152 and a power storage unit 153 in addition to the power generation unit 151 described above. The power generation unit 151 generates an alternating voltage, and the rectification unit 152 rectifies the alternating current output from the power generation unit 151 and outputs a direct current. The power storage unit 153 is for securing a voltage necessary for transmitting a radio wave having a predetermined radio field intensity, and a capacitor is used, for example.

  In addition, the notification terminal 31 illustrated in FIG. 3B includes a reception unit 301 and a notification unit 302. The receiver 301 receives a notification signal from the receiver 20. The notification unit 302 corresponds to ring-shaped light emitting units 3111 and 3211 and a vibration function.

  The notification execution condition in the example of FIG. 3 is only one condition that the radio wave received by the receiver 20 from the radio transmission unit 16 has a radio field intensity equal to or greater than a threshold value. As illustrated in FIG. 3B, the receiver 20 includes a notification control unit 202 and a notification unit 203 in addition to the transmission / reception unit 201. The transmission / reception unit 201 corresponds to an example of a reception unit according to the present invention. The notification unit 203 corresponds to the first light emitting unit 2121 to the fourth light emitting unit 2124 shown in FIG. The notification control unit 202 determines whether or not the notification execution condition of only one condition is satisfied. If the notification control unit 202 is satisfied, the notification control unit 202 instructs the notification unit 203 to notify and also registers all the information registered by pairing. A notification signal is transmitted to the notification terminals 31 and 32. As a result, among the first light emitting unit 2121 to the fourth light emitting unit 2124, the light emitting unit (notifying unit 203) corresponding to the footwear 10 that satisfies the notification execution condition emits light, and the light emitting units 31 and 32 emit light. The parts 3111 and 3211 emit light and vibration due to the vibration function (notification by the notification unit 302 together) occurs. The light emitting units of the first light emitting unit 2121 to the fourth light emitting unit 2124 (notifying unit 203 shown in FIG. 3B) provided in the receiver 20, and the light emitting units 3111, 311 provided in the notification terminals 31 and 32, respectively. 3211 and the vibration function (notification unit 302 shown in FIG. 3B) correspond to an example of the notification unit according to the present invention.

  The radio wave intensity of the radio wave transmitted from the radio transmission unit 16 is constant, and the radio wave intensity of the radio wave received by the receiver 20 depends on the receiver 20 installed at the entrance and the radio transmission unit 16, that is, the footwear 10. Will depend on the distance. In communication according to the BLE communication standard, the radio wave arrival distance reaches several tens of meters, and the radio wave intensity at the threshold is set to, for example, the radio wave intensity when the distance between the receiver 20 and the footwear 10 is 1 m. ing. For this reason, unless the person to be protected who wears the footwear 10 approaches within a range of 1 m from the entrance where the receiver 20 is installed, the notification execution condition of only one condition is not satisfied. Therefore, when the person to be protected who wears the footwear 10 approaches within a range of 1 m from the doorway, the notification in the receiver 20 itself and the notification terminals 31 and 32 is executed. As a result, in the outing monitoring system 1 shown in FIG. 3, it is possible to accurately monitor an outing person who passes through the doorway, and reduce false detections in which notification is executed by radio waves transmitted from a place away from the doorway. can do.

  Fig.4 (a) is a figure which shows 2nd Embodiment of the going out monitoring system of this invention, FIG.4 (b) is a block diagram of the going out monitoring system of 2nd Embodiment. In the following description, components having the same names as those of the components described so far will be described with the same reference numerals as those used so far.

  In the outing monitoring system 1 of the second embodiment, the receiver 20 is installed in the vicinity of an entrance / exit such as the entrance of the building B. Further, an elderly person who is a guardian wearing the footwear 10 shown in FIG. 1 is in the vicinity of the doorway. Further, the guardian possesses the notification terminal 31 shown in FIG. 2 and the communication terminal 40. The outing monitoring system 1 of the second embodiment has a configuration in which a communication terminal 40 is added to the outing monitoring system of the first embodiment shown in FIG. Hereinafter, description of the same configuration as the outing monitoring system of the first embodiment may be omitted.

  As shown in FIG. 4B, the footwear 10 is provided with a power generation unit 15 and a first wireless transmission unit 17. The first wireless transmission unit 17 has the same configuration as the wireless transmission unit 16 and is a unit that transmits electric waves having a certain electric field intensity according to the BLE communication standard using the electric energy generated by the power generation unit 151. is there. In the following description, the radio wave transmitted from the first radio transmission unit 17 is referred to as a protected radio wave. This protected radio wave corresponds to an example of the first radio wave, and the first radio transmission unit 17 is a transmission unit. It corresponds to an example.

  A communication terminal 40 unique to the outing monitoring system 1 according to the second embodiment is one in which a power supply unit 401 and a second wireless transmission unit 402 are built in a dedicated case around the neck. The power supply unit 401 is a secondary battery that is charged using a commercial power supply, but may be replaced with the power generation unit 15 provided in the footwear 10. Similar to the first wireless transmission unit 17, the second wireless transmission unit 402 is a unit that transmits a radio wave having a constant radio wave intensity in accordance with the BLE communication standard. In the following description, a radio wave transmitted from the second radio transmission unit 402 is referred to as a guardian radio wave. This guardian radio wave corresponds to an example of the second radio wave, and the second radio transmission unit 402 is a second transmitter. It corresponds to an example.

  In the second embodiment, the communication terminal 40 and the notification terminal 31 are separate units, but the power source may be shared and integrated.

  When the transmission / reception unit 201 receives the detection information from the pressure sensor 14 shown in FIG. 1, the notification control unit 202 shown in FIG. 4 sets the detection information flag to ON. Once this detection information flag is set to on, it remains on for a predetermined time (for example, 10 seconds), and returns to the off state when the predetermined time elapses. When the detection information is transmitted again within a predetermined time, the update processing is performed, and the measurement of the predetermined time is once reset and started again.

  Further, when the transmission / reception unit 201 receives a guardian radio wave having a radio field intensity equal to or higher than the second threshold, the notification control unit 202 sets the guardian radio wave flag to ON. Once this guardian radio wave flag is set to on, it remains on for a predetermined time (for example, 10 seconds), and returns to the off state when the predetermined time elapses. The radio field intensity of the second threshold here is the radio field intensity when the distance between the receiver 20 and the communication terminal 40 possessed by the guardian is 1 m. Note that, when the guardian radio wave is transmitted again within a predetermined time, the update process is performed, and the measurement of the predetermined time is once reset and started again.

  FIG. 5 is a flowchart of a notification control process executed by the notification control unit in the receiver of the outing monitoring system of the second embodiment.

  The notification control process illustrated in FIG. 5 is started when the transmission / reception unit 201 of the receiver 20 receives the protected person radio wave after the start button 213 illustrated in FIG. 2 is pressed. Note that when the stop button 214 is pressed, the notification control process is forcibly terminated.

  In the notification control process shown in FIG. 5, it is first determined whether or not the detection information flag is set to ON. If the detection information flag is not set to ON, it is assumed that the guardian is not wearing the footwear 10, and the notification control process is terminated without executing the notification. By doing this, even if a guardian or a third party moves the footwear 10 by cleaning or the like, even if power generation is performed by the power generation unit 151, it is not detected that the person has gone out, and erroneous detection can be reduced. On the other hand, if the detection information flag is set to ON, the process proceeds to step S2.

  In step S <b> 2, the transmission / reception unit 201 determines whether or not the radio wave intensity of the guardian radio wave received this time is equal to or higher than the threshold. The threshold radio field intensity here is the radio field intensity when the distance between the receiver 20 and the footwear 10 worn by the guardian is 1 m, and the second threshold radio field intensity of the guardian radio wave flag. The same. If it is determined in step S2 that the radio wave intensity of the guardian's radio wave is less than the threshold value, it is assumed that the guardian is not in the vicinity of the doorway, that is, not going out, and this notification control process is performed without performing notification. Ends. On the other hand, if the radio field intensity of the protected person's radio wave is equal to or greater than the threshold value, it is assumed that the protected person is in the vicinity of the entrance and the process proceeds to step S3.

  In step S3, it is determined whether or not the guardian radio wave flag remains off. If the guardian radio flag is set on, it is assumed that the guardian is in the vicinity of the entrance with the guardian. In this case, the guardian is going out with the guardian. Therefore, this notification control process is terminated without executing notification. In this outing monitoring system, it is recommended that the guardian pass the entrance before the guardian when passing the entrance with the guardian, and when the guardian passes the entrance, It is assumed that the guardian radio wave flag is set on. If the guardian radio flag remains off, it is assumed that the guardian is not in the vicinity of the doorway and that the guardian is alone in the vicinity of the doorway. That is, it is suspected that the user has gone out without permission or is trapped, and the process proceeds to step S4.

  In step S <b> 4, the first radio transmission unit 17 identifies the first radio transmission unit 17 that is the current radio wave received by the transmission / reception unit 201. That is, the transmission source is specified. Subsequently, among the first light emitting unit 2121 to the fourth light emitting unit 2124, the light emitting unit corresponding to the transmission source specified in step S4 (notifying unit 203 in FIG. 4B) is caused to emit light and registered by pairing. A notification signal is transmitted to all the notification terminals 31 and 32 (step S5), and this notification control process ends. In the notification terminals 31 and 32, the notification signal transmitted in step S5 is received by the reception unit 301 (see FIG. 4B), and the light emitting units 3111 and 3211 shown in FIG. 2 emit light and vibrations due to the vibration function occur. Notification by the notification unit 302 (see FIG. 4B) of the notification terminals 31 and 32 is executed.

  In the outing monitoring system 1 of the second embodiment, the conditions in the determinations of Steps S1 to S3 are notification execution conditions, and when all these three conditions are satisfied, the notification of Step S5 is executed.

  By setting the radio field intensity of the second threshold value of the guardian radio wave flag to a threshold value lower than the radio field intensity threshold value of the guardian radio wave in step S2 (for example, the radio field intensity threshold in the case of 2 m). Even if the guardian approaches the doorway one step ahead of the guardian, the notification in step S5 can be prevented from being executed.

  In the outing monitoring system 1 of the third embodiment, not the receiver 20 but the relay device 50 is installed in the vicinity of the entrance / exit of the entrance of the building B, and the receiver 20 is a room of the building B (for example, the guardian 1 Or in the case of a facility, it is installed in a manager's room or office room). As shown in FIG. 6B, the relay unit 50 is provided with a relay unit 51 that receives and relays radio waves from the wireless transmission unit 16. In the third embodiment, the relay unit 51 corresponds to an example of a receiving unit according to the present invention. As shown in FIG. 2, the receiver 20 is a relatively large one provided with the first light emitting unit 2121 to the fourth light emitting unit 2124 (informing unit 203), but the repeater 50 shown in FIG. 6. Is a very small device that is inconspicuous even when installed at the entrance of a front door or the like, and is small and easy to hide. In the third embodiment, the receiver 20 provided with the notification unit 203 is installed at a location that is different from the entrance and is easily noticed by a guardian, and the notification unit 203 provided in the receiver 20 is installed. Since it is possible to notify the guardian directly by notification, it is easy to quickly take measures to prevent the guardian from going out.

  Also in the third embodiment, a notification signal is transmitted from the receiver 20 to the notification terminals 31 and 32, and the notification terminals 31 and 32 also perform notification.

  The outing monitoring system 1 described so far has been an indoor system. However, the outing monitoring system 1 according to the fourth embodiment allows a person who is wearing a footwear 10 shown in FIG. However, it is a system that can search, and is a system in which the external communication terminal 60, the server 70, and the internal communication terminal 80 are combined with the outing monitoring system of the first to third embodiments described so far. become. Whether it is the external communication terminal 60 or the internal communication terminal 80, application software of the outing monitoring system is installed in a mobile communication terminal (for example, a smartphone), for example, Apple's iPhone (registered trademark) is an example. It is given as. The external communication terminal 60 and the internal communication terminal 80 are connected to each other via the server 70 and the Internet N.

  The radio wave transmitted from the radio transmission unit 16 shown in FIG. 7B includes unique identification information that can be distinguished from radio waves transmitted from other radio transmission units 16.

  The external communication terminal 60 is a terminal owned by a third party (for example, volunteer) outside the entrance / exit, that is, outdoors. In the external communication terminal 60, a system that performs wireless communication in accordance with the BLE communication standard is always set to ON, and the transmitter / receiver 601 automatically transmits a radio wave in accordance with the BLE communication standard. Receive. The radio transmission unit 16 incorporated in the footwear 10 worn by the person to be protected transmits a radio wave according to the BLE communication standard every time the person to be protected walks. The reach of radio waves according to the BLE communication standard is several tens of meters. In FIG. 7A, the reach of radio waves is indicated by a two-dot chain line. When the external communication terminal 60 possessed by a third party enters the radio wave reachable range, the transmission / reception unit 601 of the external communication terminal 60 transmits the radio wave including identification information transmitted from the wireless transmission unit 16. Receive automatically. In the external communication terminal 60, a position detection unit 603 and a time detection unit 604 are constructed by application software of the installed outing monitoring system. When the external communication terminal 60 receives the radio wave, the CPU 602 causes the position detection unit 603 to detect the position of the external communication terminal 60 when the radio wave is received, and also causes the time detection unit 604 to detect the time when the radio wave is received. The individual identification information (ID) of the external communication terminal 60, the detected position information, and the detected time information are associated with the identification information included in the received radio wave, and these four pieces of information are combined into one The registration information is immediately transmitted to the server 70.

  In the server 70, the transmission / reception unit 701 receives the transmitted registration information, and the CPU 702 stores the received registration information in the storage unit 703. Of the individual identification information (ID), position information, and time information, the most important information is position information, and the ID and time information can be omitted from the registration information. Further, the CPU 702 of the server 70 may store information indicating the time at which the transmission / reception unit 701 receives the registration information in the storage unit 703 in association with the received registration information.

  By storing the registration information in the storage unit 703 of the server 70, if the guardian accesses the server 70, the registration information stored in the storage unit 703 can be confirmed at any time. Further, the contact information of the internal communication terminal 80 possessed by the guardian is registered in the server 70, and the CPU 702 of the server 70 registers the discovery information indicating that the registration information has been transmitted as the registered contact information. Send first. At this time, the guardian who owns the internal communication terminal 80 also specifies the designation information for designating identification information included in the radio waves transmitted from the radio transmission unit 16 of the guardian who is taking care of himself / herself. Registered in the server 70 together with the server 70, the discovery information is transmitted from the server 70 only when a radio wave including the specified identification information is received outdoors. It should be noted that the CPU 702 of the server 70 transmits discovery information all at once every time registration information is transmitted to a contact whose registration information is not registered.

  The external communication terminal 60 includes a display screen such as a liquid crystal display device and a speaker. Since the external communication terminal 60 that transmitted the registration information can be identified based on the individual identification information (ID), the CPU 702 of the server 70 stores in the storage unit 703 of the server 70 in advance. By transmitting information such as the gender, age, and external characteristics of the guardian, such information is displayed on the display screen of the external communication terminal 60, or is output as audio from the speaker of the external communication terminal 60, and a third party. You can also search for guardians.

  In the internal communication terminal 80, a notification unit 802 is constructed by application software of the installed outing monitoring system. When the discovery information is transmitted from the server 70, the internal communication terminal 80 causes the notification unit 802 to perform notification. The notification here may be information notifying that the discovery information has been notified from the server, or in addition to this, prompting access to the server. Further, the notification mode may be a notification mode using display or a notification mode using sound. The guardian who has received this notification can access the server 70 and check whether there is information on the guardian who is taking care of himself / herself from the information stored in the storage unit 703. If there is information related to the person who is taking care of himself / herself, the person to be protected can be searched based on the position information stored in the storage unit 703.

  The internal communication terminal 80 also includes a display screen such as a liquid crystal display device and a speaker. The CPU 702 of the server 70 transmits the discovery information to the internal communication terminal 80 including the position information and the like in the discovery information, and performs notification based on the discovery information by displaying on the display screen of the internal communication terminal 80 or outputting sound from the speaker. By doing so, position information and the like can be displayed on the display screen or output from the speaker, and information on the person who is taking care of themselves can be acquired without accessing the server 70. It is possible to find the protected person as soon as possible.

  Even if the radio wave transmitted from the wireless transmission unit 16 does not include identification information, it is at least known that someone using this system has gone out, and the search is performed even if the outsider remains unknown. Can do. Further, the registration information itself may be transmitted to the internal communication terminal 80 as discovery information without storing the registration information in the server 70.

  Further, the function of constructing the notification unit 302 of the notification terminal 31 shown in FIG. 3 and the like and the notification unit 302 of the notification terminal 31 shown in FIG. 4 are built in the application software of the outing monitoring system installed in the internal communication terminal 80. A function and a function of constructing the second wireless transmission unit 402 of the communication terminal 40 may be included. In this way, the role of the notification terminal 31 shown in FIG. 3 and the like and the role of the notification terminal 31 and the communication terminal 40 shown in FIG. Only the internal communication terminal 80 is required.
