  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings. In addition, although the local crime prevention system for children is described here, it can be applied to kindergarten children as well.

≪System configuration and overview≫
FIG. 1 is a diagram showing a configuration of a local crime prevention system according to an embodiment of the present invention. The local security system 100 is a system that performs the route and behavior of children attending school, video monitoring, entrance / exit management for elementary schools, location monitoring in local parks, etc. The purpose is to discover. The local security system 100 includes a wireless tag-attached name tag 1, a security light (monitoring device) 2, an access point 3, a security bulletin board 4, a monitoring terminal (monitoring condition setting device) 5, a reception device (management device) 6, a gate sensor 7 and A network 8 is included.

  The name tag 1 with a wireless tag is a name tag worn by a child who goes to and from school (for example, on the left chest), and a wireless tag, a sensor, or the like is incorporated in the name tag. Accordingly, the location of the child can be monitored, and when the emergency occurs, the child can press the name tag 1 with the wireless tag to transmit a message to that effect. A solar panel may be attached to the name tag 1 with the wireless tag. The wireless tag name tag 1 can directly communicate with the crime prevention light 2. However, ad hoc wireless LAN communication (hereinafter referred to as ad hoc communication) for communicating with other wireless tag name tags 1 can be It is also possible to communicate with the security light 2 via the other name tag 1 with the above-mentioned wireless tag. According to this, for example, even when a child is in a narrow passage or tunnel and the name tag 1 of the child's wireless tag cannot communicate directly with the security light 2, the name tag 1 of the other child's wireless tag is attached. It is possible to communicate with the security light 2 indirectly via the. The detailed configuration of the wireless tag-attached name tag 1 will be described later.

Here, in ad hoc communication, it is known that the data transmission rate (unit: Mbps) attenuates every time (hops) through a normal communication node. However, since the data transmitted by the name tag 1 with the wireless tag is a tag ID or an emergency message, the data amount can be said to be very small. Therefore, attenuation of the data transmission rate does not become a big problem, and it is considered that about 10 hops are possible, for example.
The name tag 1 with the wireless tag is assumed to always perform ad hoc communication. This is made possible by a power source such as a button battery. And according to ad hoc communication, since tag ID can be received also from the name tag 1 with a wireless tag outside the communication range of the security light 2, even if the predetermined security light 2 receives the tag ID, the tag ID Is not necessarily within the communication range of the predetermined security light 2. Therefore, when it is necessary to determine whether or not the received tag ID is within the communication range of the security light 2 (when it is desired to know the position of the child with a predetermined accuracy), is the number of hops less than or equal to the predetermined value? Check whether or not.

  The security light 2 is installed in a street or a park, and integrates a surveillance camera, a lighting device, a wireless LAN (Local Area Network) device, a flash siren (rotary light / buzzer), and the like. The security light 2 is not only a lighting device that performs the function of a normal security light, but also a surveillance camera for monitoring the surroundings, a name tag 1 with a wireless tag, an access point 3, and a wireless LAN device that communicates with another security light 2 , Equipped with flash siren etc. to inform the surroundings of emergency situations. Here, as a feature of the crime prevention light 2, the tag IDs of the wireless tag-added name tags 1 within the communication range are periodically collected, and the collected tag IDs are further periodically transmitted to the reception device 6. When the security light 2 is installed on a street, the surveillance camera is preferably of a vertical rotation type (with a video reversing function). When the security light 2 is installed in a park, the monitoring camera is preferably a 360-degree monitoring type. The security light 2 can directly communicate with the access point 3 and the security bulletin board 4, but via ad hoc communication that communicates with other security lights 2 via one or more other security lights 2. It is also possible to communicate with the access point 3 and the security bulletin board 4. According to this, since the communication work between security lights becomes unnecessary, the cost concerning the installation work of security lights can be reduced. The detailed configuration of the security light 2 will be described later.

  The access point 3 is installed, for example, at a dispatching station, and performs a relay function by communicating with the security light 2 and also communicating with the network 8. Here, the contents received at the access point 3 may be notified to the police officer stationed at the dispatch station. The security bulletin board 4 is installed in a place where people can easily gather, such as a park and a facility lobby, and is used for sharing crime information and other security information generated in the area. The security bulletin board 4 may function as the access point 3 in some cases. Details of the security bulletin board 4 will be described later.

  The monitoring terminal 5 is installed in an elementary school, a vigilante group, a monitoring volunteer, a home, a police station, and the like, and can monitor a route and behavior of a child who is going to and from school. The monitoring terminal 5 is realized by a PC (Personal Computer), a digital television, or the like. The monitoring terminal 5 is connected to the network 8 and has a monitoring browser installed therein, thereby realizing child location GIS (Geographical Information System) and monitoring display / report operation HMI (Human Machine Interface) basic specifications. Note that the elementary school monitoring terminal 5 relays between the gate sensor 7 and the network 8.

  The reception device 6 is installed in a police station, and can receive information sent via the network 8 and display the information on a screen or determine the absence of a child. The accepting device 6 includes the function of the monitoring terminal 5, but realizes other functions that should be provided exclusively for the police station. Details of the configuration and functions of the accepting device 6 will be described later.

  The gate sensor 7 is installed at the school gate of the elementary school, reads the tag ID from the name tag 1 with the wireless tag of the child passing through the school gate, and transmits the tag ID and the passing direction to the monitoring terminal 5. The monitoring terminal 5 transmits the information to the accepting device 6 via the network 8. As a result, the monitoring terminal 5 of the elementary school or the reception device 6 of the police station can manage entrance / exit of the child and can cancel or activate the monitoring operation related to the tag ID accordingly. Note that the gate sensor 7 may be directly connected to the network 8.

  The network 8 is a communication network that connects the access point 3, the security bulletin board 4, the monitoring terminal 5, and the reception device 6, mainly for sending information from the access point 3 and the security bulletin board 4 to the monitoring terminal 5 and the reception device 6. Used. Specifically, the network 8 is realized by a high-speed communication line or a wireless LAN line.

≪Configuration of security light≫
FIG. 2 is a diagram illustrating a configuration of a self-supporting crime prevention light. There are two types of self-supporting crime prevention lamps 2 including a main notification device 2a and a sub notification device 2b, and each security light 2 is connected via a wired LAN. The main notification device 2a is connected to the accepting device 6 via a high-speed communication line. The main notification device 2 a includes a notification device 21 and a control device 22. The reporting device 21 includes a lighting device 212, a monitoring camera 213, a rotating lamp / buzzer 214, a display panel 217, a reporting camera, a reporting button / microphone, and the like. The reporter camera captures an image of the reporter, and the captured image is transmitted to the reception device 6 of the police station through a high-speed communication line. The notification button / microphone can be used to communicate with a person in charge at the police station reception device 6 through an interphone when pressed by the reporter when an emergency such as an incident or accident occurs. The secondary notification device 2b includes the notification device 21 and does not include the control device 22. By installing such a crime prevention light 2 on the street, it becomes possible to report when an emergency occurs, and since the installation of the crime prevention light 2 capable of making an emergency notification is well known, crime is less likely to occur in the vicinity. The effect is also demonstrated. Individual details will be described later.

  FIG. 3 is a diagram showing a configuration of a utility pole retrofit security light different from FIG. The pole-type retrofit security light 2 is different from that shown in Fig. 2 and can be retrofitted to existing power poles, telephones, and other poles. Cost can be reduced. This is because the installation work of the pole is not necessary, and the communication work between the security lights is not required because the ad hoc communication is used for the communication between the security lights. According to this, it is thought that it is effective for temporary installation in the case of a show, a festival, etc., and patrol installation around a park or school. Of course, the one in FIG. 3 may be connected by a wired LAN or a high-speed communication line, or the one in FIG. 2 may be connected by a wireless LAN (ad hoc communication) or a wireless LAN line. In addition, the structure itself of the telephone pole retrofitting type security light is the same as that of the self-supporting type. In addition to the self-supporting type and the utility pole retrofitting type, there is also a crime prevention light called a bollard type having a height of about 1 m, for example.

  FIG. 4 is a diagram illustrating a detailed configuration of the security light and the reception device. As already described, regardless of whether it is a self-supporting type or a utility pole retrofitted type, the main reporting device 2a for the crime prevention light is composed of the reporting device 21 and the control device 22, and the secondary reporting device 2b is composed of the reporting device 21. The notification device 21 is connected to the control device 22 via a LAN (wireless / wired), and the control device 22 is connected to the reception device 6 via a high-speed communication line / wireless LAN line.

  The notification device 21 includes a control unit (tag ID notification unit) 211, a lighting device 212, a monitoring camera 213, a rotating lamp / buzzer 214, a communication unit (wireless transmission / reception unit) 215, a notification operation unit 216, a display panel 217, and a pole 218. Consists of including. The control unit 211 is a board that performs various controls. For example, the control unit 211 compresses video captured by the monitoring camera 213, compresses audio input from a microphone, and expands audio received from the reception device 6. The control unit 211 includes a CPU (Central Processing Unit) and a memory, and the function is realized when the CPU executes a program loaded in the memory. The illuminating device 212 is a white fluorescent lamp that illuminates the periphery of the security light 2, but it may be illuminated by a white LED (Light Emitting Diode). For example, the monitoring camera 213 can shoot under an average illuminance of 3 “lx” and can shoot an arbitrary direction by remote control. The revolving light / buzzer 214 rotates an alarm light and sounds an alarm sound. Specifically, it is an outdoor installation type, for example, a flash siren or a patrol light (registered trademark) is used. For example, when the communication unit 215 receives an emergency occurrence message from the wireless tag-attached name tag 1, the control unit 211 operates the rotating lamp / buzzer 214. As a result, it is possible to notify the surroundings of the occurrence of an emergency situation and to urge the criminal acts to be stopped.

  The communication unit 215 performs communication with the control device 22 and performs communication in accordance with a LAN interface compliant with TCP / IP (Transfer Control Protocol / Internet Protocol). The report operation unit 216 is a part that is operated when the reporter wants to report to the police station, and includes the reporter camera, report button / microphone / speaker already described. The display panel 217 indicates that the device is a security light and can make an emergency call, and is written “SOS 110”. The display is preferably colored red so as to be noticeable. The pole 218 is unique to a self-supporting security light and is used when a security light is newly installed. Therefore, the pole 218 is not used for a utility pole retrofit security light.

  The control device 22 constitutes the main notification device 2 a and includes a control unit 221 and a communication unit 222. The control unit 221 performs a function of relaying communication between the reporting device 21 and the receiving device 6. The control unit 221 includes a CPU and a memory. When the CPU executes a program loaded in the memory, the function is performed. Realized. Further, the control unit 221 not only relays and manages communications, but also manages data such as videos sent from each reporting device 21. The communication unit 222 realizes communication with the reporting device 21 and communication with the accepting device 6. The number of reporting devices 21 that can be connected to one control device 22 is, for example, 18 as a standard and 64 as a maximum.

  The reception device 6 includes a control unit (confirmation unit) 61, an operation terminal 62, a rotating lamp / buzzer 63, a communication unit (tag ID acquisition unit) 64, a microphone / speaker 65, a video recording unit 66, and a large monitor 67. Is done. The control unit 61 is a board that performs various types of control. For example, the control unit 61 expands the video that is captured and sent by the monitoring camera 213 of the notification device 21, compresses the audio input from the microphone, The received voice is expanded. The child's location is confirmed by comparing the tag ID of the child registered in a predetermined memory (storage unit) with the tag ID received by the communication unit 64. The control unit 61 includes a CPU and a memory, and the function is realized when the CPU executes a program loaded in the memory. The operation terminal 62 is a terminal operated for scrolling the map on the screen (changing the display range), adjusting the display magnification, switching the video, and controlling the direction of the monitoring camera 213 and the zoom magnification. Specifically, a screen connected to the accepting device 6, a keyboard, a mouse, and the like. The rotating lamp / buzzer 63 rotates an alarm lamp and sounds an alarm sound. Specifically, it is an indoor installation type, for example, a flash siren or a patrol light (registered trademark) is used. This clearly informs police officers that an emergency has occurred.

  The communication unit 64 is connected to the communication unit 222 of the control device 22 via a high-speed communication line / wireless LAN line, and performs communication with the communication unit 222. The microphone / speaker 65 is a microphone and a speaker for the person in charge of the police station to talk to the reporter when the reporter presses the report button in the reporting device 21. The video recording unit 66 records video sent from the control device 22, and is specifically a recorder such as video, DVD (Digital Versatile Disk), HDD (Hard Disk Drive) or the like. The large monitor 67 is a monitor for projecting a video or a map sent from the control device 22.

≪Configuration of name tag with wireless tag≫
The wireless tag-attached name tag 1 is a name tag worn (possessed) by a child for crime prevention. However, since the appearance is a normal name tag, there is no sense of incongruity. And although the security school bag may be placed when playing, the name tag 1 with the wireless tag is always worn by the child, so that the surveillance for crime prevention can be surely performed. In addition, it can be said that it is more natural for children to wear the name tag 1 with a wireless tag than to carry a wristwatch or a pocket watch with a GPS function.

  FIG. 5 is a diagram illustrating an internal configuration of the name tag with the wireless tag. The wireless tag-attached name tag 1 includes a wireless tag 11, a wiring 12 and a pressure sensor 13. The wireless tag 11 includes an ad hoc communication unit 11a including an antenna, a transceiver, a CPU, a memory, and the like, and a power supply unit 11b such as a button battery. And according to the transmission request message regularly sent from the security light 2, tag ID etc. which were previously memorize | stored in memory are transmitted. This is performed by ad hoc communication between the wireless tags 11. For example, a communication standard called ZigBee (IEEE 802.15.4) having a communication distance of 10 to 75 m is applied to the wireless tag 11. The wiring 12 is a wiring that electrically connects the wireless tag 11 and the pressure sensor 13. The pressure sensor 13 is a sensor that transmits an electrical signal to the wireless tag 11 in response to a child touching or pushing around the wireless tag-attached name tag 1. Instruct children to press the end (pressure sensor 13) of the wireless tag-attached name tag 1 at a predetermined pressing force or more for a specified time when they feel a danger during school. When the child pushes the end of the wireless tag-attached name tag 1 as such, the pressure sensor 13 transmits an electrical signal to the wireless tag 11 through the wiring 12. When the wireless tag 11 receives the electric signal, the wireless tag 11 voluntarily transmits a message indicating the occurrence of an emergency together with the tag ID. This is performed by ad hoc communication between the wireless tags 11. The tag ID and the message are received by the monitoring terminal 5 and the reception device 6 via the security light 2 and displayed on the screen, so that an emergency situation of the child can occur in the parent of the family or the person in charge of the police station. Informed. Further, when the security light 2 receives an emergency message, the revolving light / buzzer 214 may be activated as a warning by light or sound.

  Since the pressure tag 13 is installed in the name tag 1 with the wireless tag so as to surround the periphery with a predetermined width, the pressure sensor 13 reacts wherever the child presses. According to this, when a child feels danger like a normal button, he / she is confused and misplaces the button so that it cannot be pushed easily. Further, the name tag 1 with the wireless tag can be used any number of times because the pressure sensor 13 is used instead of the disconnection sensor or the like. Furthermore, if the child continues to push the name tag 1 with the wireless tag, an electric signal is continuously sent from the pressure sensor 13 to the wireless tag 11, and the wireless tag 11 transmits an emergency message to the security light 2 during that time. Will continue to do. According to this, for the side monitoring the child with the monitoring terminal 5 or the reception device 6, the clear intention indication that the child “recognized the emergency” is confirmed by continuously receiving the emergency message. can do. In other words, misinformation caused by mischief or unconscious actions can be prevented. In addition, you may attach a disconnection sensor and a security buzzer (not shown) to the name tag 1 with a wireless tag. The disconnection sensor is, for example, built in a string that links the wireless tag-attached name tag 1 with a school bag or clothes, and reacts by tearing the string in the event of an emergency to trigger message transmission. The security buzzer sounds an alarm sound when an emergency occurs.

  Although the pressure sensor 13 is described as being used, a strain sensor, an acceleration sensor, or a combination thereof may be used. The feature of the sensor used here is not a clear mechanism such as a switch, but is that it is difficult to be sensed by a suspicious partner, and it is detected by a natural movement that it is in a dangerous state. Therefore, in addition to pressing the name tag 1 with the wireless tag, for example, a sensor that reacts by an operation of twisting or gripping the name tag 1 of the wireless tag or an operation of pressing and holding the hand on the chest may be used.

≪Security Bulletin Board Configuration≫
FIG. 6 is a diagram showing a configuration of the security bulletin board. The security bulletin board 4 is installed in a place where people can easily gather, such as a park and a facility lobby, and is used for sharing crime information and other security information generated in the area. The security bulletin board 4 includes a communication unit 41, a display unit 42, and a control unit 43. The communication unit 41 includes an antenna and a transmitter / receiver installed around the display unit 42, and communicates with the security light 2 and the network 6. The communication unit 41 has a function of transmitting information written on the display unit 42 and also has an access point function for the security light 2. The display unit 42 is a plasma display, and information can be easily written by a touch panel type. The written information is transmitted to the monitoring terminal 5 and the receiving device 6 through the network 6 so that the parent at home or the person in charge at the police station can refer to the information.

  Note that the security bulletin board 4 can display a screen for bidirectional communication with a remote place (home or police station) and can be used like a video conference. It is also movable with casters and is a dust-proof housing. Further, the crime prevention bulletin board 4 may also serve as the crime prevention light 2, and an alarm operation may be performed by displaying a large screen of the display unit 42 instead of a revolving light or a buzzer. Furthermore, the crime prevention bulletin board 4 can respond to an emergency in a park by providing a notification function and a dialog function using a monitoring camera, a notification button, a microphone, a speaker, and the like.

≪System processing≫
Then, the process of the local crime prevention system which concerns on embodiment of this invention is demonstrated. FIG. 7 is a diagram illustrating an example of a school route map. This map shows the route to school for a certain child X. Child X goes to the elementary school near the center from his home in the lower right as viewed in the drawing. Security lights 2 (2A, 2B, 2C, 2D, 2E, and 2F) are installed on the school road and the surrounding intersections. Then, by covering the school route with a communication range centered on the security light 2 (radius is about 100 m, hereinafter referred to as a zone), the child X who is going to and from school wearing the name tag 1 with the wireless tag Can perform location management and safety confirmation. Here, since the school route of the child X is as the broken line shown in FIG. 7, for example, as a scheduled course at the time of going to school, it becomes the order of zone ZF->ZE->ZD-> ZA. In this order, the child X may be monitored or given a certain degree of freedom. The starting point is the zone ZF, the reaching point is the zone ZA, and any of the zones ZB, ZC, ZD and ZE is in the middle. It may be monitored that it is sufficient to stay in the room. Further, it may be monitored that it is only necessary to be in one of the zones ZA to ZF regardless of the order. Moreover, it is good also as a range which should monitor the attending school area of the elementary school.

  In order to determine whether or not the vehicle has entered a danger zone (river, pond, construction site, downtown area, etc.), it is conceivable to first detect that it is not in any of the zones ZA to ZF. This is a relatively simple determination method. Next, it is conceivable to point out the possibility of reaching a dangerous area in the vicinity of the zone ZA or ZF after having been in a predetermined zone until now. In the case of FIG. 7, for example, there are rivers, bridges B1 and B2 and construction sites as dangerous areas. Accordingly, if the location is unknown after being in the zone ZA, ZB, ZD or ZE, it may be pointed out that the person may have entered the danger zone. Moreover, the zone does not need to be circular, and may be elliptical so as to cover a linear flow line such as a school route. Further, by installing a security warning light 2 for danger warning in the vicinity of the boundary of a river or a construction site, it is possible to detect intrusion into a dangerous area. When the intrusion is detected, the security light 2 may notify the accepting device 6 or drive the security buzzer of the name tag 1 with the wireless tag or the rotating light / buzzer 214 of the security light 2 to warn the child of the danger. May be.

  FIG. 8 is a flowchart showing the processing of the local security system. First, the tag ID of the wireless tag-added name tag 1 and the scheduled course at the time of going to and from school are registered in advance from the home monitoring terminal 5 to the reception device 6 of the police station (step S801). Here, the tag ID is an ID stored in the memory of the wireless tag 11 built in the name tag 1 with the wireless tag. The scheduled course at the time of going up and down school is, for example, the order of zones through which the child passes, as described with reference to FIG. The receiving device 6 receives these and stores them in a predetermined memory (such as a hard disk device). Next, the monitoring start at the time of going to school is set from the monitoring terminal 5 (step S802). This requests the reception device 6 to start monitoring the child when the child leaves the home for attending school. At this time, the monitoring terminal 5 transmits a tag ID and a monitoring start request message to the receiving device 6.

  Then, the accepting device 6 starts monitoring the tag ID of the wireless tag-added name tag 1 (step S803). Specifically, according to the previously stored zone, it is checked at any time whether or not the tag ID is present in the tag ID periodically sent from the security light 2 corresponding to the zone. During the monitoring, it is checked whether or not the child has entered (entered) the elementary school (step S804). Specifically, it is checked whether or not the tag ID is sent from the gate sensor 7 installed in the school gate. If it is not in the elementary school (No in step S804), it means that it is still in the middle of school, so it is checked whether or not it is in the zone scheduled for school (step S805). If in the scheduled zone (Yes in step S805), the process returns to the check in step S804. If it is not in the scheduled zone (No in step S805), the accepting device 6 notifies the monitoring terminal 5 of the emergency (step S806). Specifically, an emergency message is transmitted. In this case, in the receiving device 6, the control unit 61 operates the rotating lamp / buzzer 63. As a result, it is possible to notify the person in charge at the police station of the occurrence of an emergency and to encourage the child to search. In addition, the monitoring terminal 5 receives an emergency occurrence message and sounds a sound. As a result, the occurrence of an emergency situation can be notified to a parent or the like at home, and a response can be promoted.

  If the child has entered the elementary school (Yes in step S804), it means that the child has safely reached the elementary school, and therefore the reception device 6 cancels the monitoring of the tag ID (step S807). After a few hours, the receiving device 6 receives the tag ID from the gate sensor 7 at the school gate (step S808), and when the child recognizes that the child has left the elementary school (goes to school), starts monitoring the tag ID again. (Step S809). If the child is not in the zone scheduled for leaving school (No in step S810), the reception device 6 notifies the monitoring terminal 5 of the emergency (step S806). If it is in the scheduled zone (Yes in Step S810), it is checked whether or not the monitoring cancellation is set by the child's arrival at the home from the monitoring terminal 5 (Step S811). If there is no setting for monitoring cancellation (No in step S811), the check in step S810 is performed again. If there is a setting for canceling the monitoring (Yes in step S811), it means that the child has safely arrived at the home, so the receiving device 6 cancels the monitoring of the tag ID (step S812). Then, it again waits for a monitoring start request when going to school.

  This flowchart was written focusing on the monitoring of a single child, that is, one name tag 1 with a radio tag. Checking the entrance and exit of an actual elementary school and the location in a planned zone, It is performed collectively within the range of the registered tag ID. Moreover, in the flowchart demonstrated above, although it set as the process centering on the setting from the monitoring terminal 5 in a home, and the monitoring of the child by the reception apparatus 6 in a police station, one or more monitoring different from the reception apparatus 6 is carried out. The terminals 5 may cooperate to monitor children in a lump, or the monitoring terminals 5 in each household may be controlled to monitor their respective children (children).

  In the flowchart of FIG. 8, it has been described that the child is monitored according to the pre-registered scheduled course at the time of attending school and leaving the school, but here, an exception of the monitoring will be described by a specific example. First, children may leave the school area (school district) for excursions and social tours. In that case, it is necessary not to perform monitoring even if the student leaves the school after entering the elementary school. In such a case, a setting for canceling the monitoring of the child in units of classes is performed from the monitoring terminal 5 of the elementary school by the authority of the principal. With this setting, the reception device 6 can be prevented from monitoring children of the class.

  Next, after leaving the elementary school, you may be asked to leave at your neighbor without going home. In that case, there is no problem with monitoring halfway, but it is not possible to reach home for a while, so it is necessary to avoid monitoring. In such a case, a setting for canceling monitoring of a child (child) from the home monitoring terminal 5 is performed according to the authority of the parent. For example, when the child arrives at the neighbor, he / she contacts the home, and the monitoring cancellation may be set when the parent receives the notification. With this setting, the reception device 6 can be prevented from monitoring the child.

  Subsequently, for example, a child may be sent by a car such as a friend's parent. In that case, after leaving the school route or school area, you may come back and eventually be sent to your home. In that case, it is necessary not to perform monitoring in the school route or school area within a predetermined time. In such a case, the time allowed for the child (children) to leave the school road is set from the home monitoring terminal 5 by the parent's authority. With this setting, when the reception device 6 monitors the child, even if the reception device 6 is not in any zone covering the school route, the emergency device is not notified within the set time. Can be. In any case, the temporary exception setting in the reception device 6 is canceled in the morning of the next day, and the child is monitored according to the scheduled course as usual.

  In the above description, it is described that a wireless tag having a predetermined tag ID is present in a predetermined area in a predetermined time zone, but another monitoring method may be used. For example, instead of managing the location of an individual called a wireless tag, the number of wireless tags in the set is monitored while monitoring the movement of the set, taking the set of individuals existing in a predetermined range as the number of wireless tags. It can be considered that a change (for example, a decrease) in is considered abnormal.

≪Countermeasures for mischief and misinformation≫
The crime prevention light 2 is provided with a report button. When an emergency situation occurs, by pressing the report button, a call can be made with a person in charge at the police station reception device 6. However, the report button is often pressed due to mischief or misinformation. A measure for preventing this will be described.

  First, the target person of the countermeasure is a person who does not have the wireless tag-added name tag 1. It should be noted that education and guidance shall be thoroughly provided to children who have the name tag 1 with the wireless tag so as not to press the notification button by mischief. As a specific countermeasure method, a voice message is transmitted to a person in the vicinity of the security light 2 so as not to press the notification button due to mischief or misinformation. Further, the voice and content of the message are made appropriate depending on the distance between the person and the security light 2, the time that the person is, and the like. Here, it is assumed that the security light 2 has a sensor (for example, a well-known human sensor) that detects the presence of a person.

  For example, a message “What have you done?” Is sent to a person who is within a few meters of the security light 2 and stays within a few minutes. Although this may cause the person to press the notification button immediately, it is transmitted to let the user know that the security light 2 is nearby. Therefore, the contents are not disturbing. This also has the effect of preventing possible mischiefs and misinformation in the future.

  Also, for people who are about several tens of centimeters (close to) from the security light 2, for example, "If you press with mischief, you will be punished by law", "Recorded by a surveillance camera" , “Please do not press with mischief”. This is a reconfirmation of the will to press the report button because an emergency has occurred. In addition, you may make it send a message with the voice of the principal as a measure which considered the child. For example, it is assumed that a certain child Y approaches the security light 2 trying to mischief in an area outside the school district. Therefore, the control unit 211 of the security light 2 recognizes that the tag ID of the wireless tag-attached name tag 1 worn by the child Y is outside the school district, and tries to send a tampering prevention message. In this case, if the reception device 6 is inquired, the school district of the child Y can be known from the tag ID, so a message is transmitted with the voice of the principal of the elementary school in the school district. According to this, the child Y receives the impression that the school principal is paying attention, so the effect of preventing mischief is greatly exhibited.

  In this way, a predetermined deterrence message is sent to people who do not have the wireless tag name tag 1 or to children outside the school district, so that the intention of reporting can be confirmed, and mischief and misinformation can be prevented. it can.
