  Specifically, Patent Document 3 has a function of detecting that the monitored person has moved out of the specific area, entered the specific area, or that the movement of the monitored person is abnormal. An area monitoring system is disclosed. In particular, this area monitoring system requires a GPS (Global Positioning System) mobile phone carried by the monitored person, and requests location information from the GPS mobile phone according to a predetermined schedule. And a position search center that receives position information from the position search center, and when the position information is outside or within a predetermined area defined by the monitor in advance by e-mail to the mobile phone of the monitor And a service center for reporting. As a result, in this area monitoring system, if the monitored person is within the range of the normal action area, it is not necessary for the monitoring person to check the position one by one. Since the telephone is used, the person being monitored can carry it without resistance.

  Patent Document 4 discloses a child crime prevention notification method for automatically notifying a child's guardian of arrival or non-arrival of a child at school. In particular, in this child crime prevention reporting method, a child ID and a child's action schedule data are registered in a data server, and when the child leaves home and heads for school, the wireless tag device is used to read from the wireless tag device. The child ID is read, the child ID and the school start time are transmitted to the data server, and the expected school completion time of the child is calculated by the data server based on the action schedule data and the school start time. And in this child crime prevention reporting method, when the child arrives at the school, the child ID is read from the wireless tag device using the wireless reading device, and the child ID and the school completion time are transmitted to the data server, while the school completion is completed. If the data server does not receive the child ID and the school completion time even after a predetermined time has passed beyond the expected time, an emergency notification is transmitted to the guardian. Moreover, in this child crime prevention reporting method, the same processing is performed even when leaving school. As a result, in this child crime prevention reporting method, a notification will be sent to the guardian if school attendance or school leaving is not completed even after a predetermined time has elapsed beyond the expected school attendance or school attendance completion time calculated from the child's action schedule. Therefore, it is said that parents can be alerted at an appropriate time for crime prevention of children.

  Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings.

  This embodiment is a monitoring system for monitoring a predetermined monitored object. This monitoring system is operated by a security company. By constructing an infrastructure using a wireless network such as a wireless local area network (LAN) in the city, the monitored object can be manufactured at low cost. The position of can be surely grasped. In addition, this monitoring system can perform comprehensive monitoring of the monitoring area by arranging a facility for monitoring control and a moving body for patrol for each monitoring area having a predetermined area. It is.

  The monitored object is a concept including various items such as a vending machine installed in the city and a vehicle parked outdoors in addition to a human being such as a child attending or going to school. In the following, for convenience of explanation, a case will be described in which children who are going to and from school are monitored as monitored objects.

  As shown in FIG. 1, the monitoring system includes, for example, a control center 11 as a headquarters control facility provided in a metropolitan area and a plurality of regional control facilities 12 provided for each predetermined monitoring area. (Internet Protocol) It is configured to be connected via a predetermined network such as a network or a telephone line.

  The control center 11 is a facility owned by a security company that operates the monitoring system, and is provided in a metropolitan area, for example. Although not specifically shown, the control center 11 can communicate with a plurality of regional control facilities 12 via a network network 24 hours a day. In addition to giving a command, it receives and accumulates various data such as notification of abnormal situations and image data and audio data transmitted from each regional control facility 12. Thereby, the control center 11 can always monitor the state of the monitoring area controlled by each regional control facility 12 via a multi-monitor or the like.

  The regional control facility 12 is a facility owned by a security company that operates the monitoring system. For example, the regional control facility 12 is provided for each region having a radius of 800 m, and performs monitoring control on a 24-hour basis using this region as a monitoring area. The area having a radius of 800 m is merely an example, and the area control facility 12 may be provided for each area having an arbitrary area such as a radius of 500 m or 300 m, for example. The regional control facility 12 can communicate with the control center 11 and a patrol vehicle 13 to be described later, in addition to various commands from the control center 11, the patrol vehicle 13 and / or a school as a monitoring target. Various types of data including image data, audio data, and the like are received and stored, and notification of occurrence of an abnormal situation and various types of data are transmitted to the control center 11. In addition, the regional control facility 12 is configured to be able to receive communication device transmission data, which will be described later, transmitted from a communication device functioning as an access point constituting a wireless LAN constructed in the monitoring area. When the data indicates that an abnormality has occurred, a notification to that effect is sent to the control center 11, and a child SC such as a school staff or a child guardian existing in the monitoring area. An e-mail or the like indicating that can be transmitted to a mobile communication terminal such as a mobile phone or a personal digital assistant (PDA) possessed by the user requesting the monitoring. Furthermore, even if an abnormal situation occurs at a school, the regional control facility 12 provides electronic information indicating that to a mobile communication terminal possessed by a user such as a staff of the school or a guardian of a child. E-mails can be sent. Furthermore, the regional control facility 12 can receive a report from a school existing in the monitoring area.

  In such a monitoring system, each regional control facility 12 has a plurality of guards stationed in a system that can always be dispatched, and a traveling vehicle 13 as a moving body is provided.

  The traveling vehicle 13 is equipped with a so-called pan / tilt / zoom (PTZ) camera having a pan and tilt function in a predetermined direction and a zoom function at a predetermined magnification, and an omnidirectional camera for imaging in all directions. Yes. In addition, the traveling vehicle 13 may be movable and / or fixed imaging auxiliary illumination devices such as illumination devices that emit visible light, infrared light, laser light, etc., in order to enable appropriate imaging regardless of day or night. It is equipped with. The traveling vehicle 13 acquires image data and audio data including moving images using these various cameras and records them sequentially to the regional control facility 12 in order to record the situation during the traveling. At this time, the traveling vehicle 13 transmits data to the regional control facility 12 via a dedicated wireless LAN constructed by an access point for wireless transmission. Further, the position information of the patrol vehicle 13 is grasped using a so-called GPS (Global Positioning System) and is sequentially transmitted to the regional control facility 12 via the wireless LAN.

  At least four such traveling vehicles 13 are provided in the monitoring area, and each vehicle periodically circulates within a range of, for example, a radius of 400 m. Thereby, in the monitoring system, the crime deterrent effect can be remarkably improved only by patrol the patrol vehicle 13. The radius of 400 m is a distance that, on average, it takes about 5 minutes on foot and about 2 minutes to run for humans to move. On the other hand, the action time of a criminal who performs intrusion or the like is usually said to be about 5 minutes. Therefore, in the monitoring system, it is possible to establish an extremely high-density monitoring system that can always arrive within 2 minutes from the detection of the occurrence of an abnormal situation to the site where the abnormal situation occurs. It is possible to provide the user with a sense of security that cannot be compared with the arrival within 25 minutes.

  Now, in such a monitoring system involving a patrol by the patrol vehicle 13, for example, as shown in FIG. 2, in each monitoring area, for example, IEEE (Institute of Electrical and Electronic Engineers) 802.11a, b, e, g A communication device 100 that functions as an access point for constructing a wireless LAN that conforms to a predetermined wireless transmission method such as a standard or so-called Bluetooth (Bluetooth®) is installed, and data is transmitted via the plurality of communication devices 100. By routing, not only between the school and the regional control facility 12 and the patrol vehicle 13, but also the data can be transmitted and received between the patrol vehicle 13 and the regional control facility 12, and the locator terminal 200 is provided. Build an infrastructure that will allow you to know the location of the children's SCs that are in and out of school.

  Specifically, the communication device 100 is attached to a building such as a house or a utility pole that faces the school route of the child in the monitoring area, and is installed at a pitch of about 50 m, for example. Further, each communication device 100 is given unique identifier information. Further, the communication device 100 receives the terminal transmission data transmitted from the locator terminal 200, and routes the communication device transmission data generated based on the terminal transmission data using the wireless LAN. Transmit to the control facility 12. In addition, the communication device 100 may include image data and audio data captured and / or acquired by a camera or microphone (not shown) attached to the installed building as necessary, and an electronic device indicating that an abnormal situation has occurred. An e-mail or the like may be transmitted to the regional control facility 12, the patrol vehicle 13 traveling in the vicinity as necessary, and further to the mobile communication terminal possessed by another user.

  On the other hand, the locator terminal 200 is possessed by a child SC who is going to and from school, and includes, for example, a push button 201 and an LED (Light Emitting Diode) on a predetermined housing surface as shown in FIG. The light emitting element 202 is configured to be exposed. Note that a string passage hole 203 through which a string body such as a strap is inserted is formed in the housing so that the child SC can easily carry it. As shown in FIG. 4, the locator terminal 200 is internally generated in the locator terminal 200 according to a control circuit 211 composed of a CPU (Central Processing Unit) and the like and a behavior such as walking by the child SC. The vibration switch 212 for transmitting vibration to the control circuit 211, the push button switch 213 for transmitting to the control circuit 211 that the push button 201 has been pressed, and the light emission described above that emits light under the control circuit 211. An element 202; a buzzer 214 that outputs a predetermined sound under the control circuit 211; and a specific low-power transmission circuit 215 that transmits terminal transmission data including a pulse wave generated by the control circuit 211 via the antenna 215a. , A setting machine 300 provided in the regional control facility 12 shown in FIG. 2, a guard or a patrol vehicle 1 stationed in the regional control facility 12. Such guards that ride and a LF coil 216 and LF circuit 217 communicating with the notification stop device 400 that possession.

  For example, as shown in FIG. 5, such a locator terminal 200 controls the control circuit 211 while detecting vibrations generated by the child SC walking or the like via the vibration switch 212. In addition, terminal transmission data including identifier information unique to the locator terminal 200 is transmitted through a specific low power transmission circuit 215 in, for example, an ARIB (Association of Radio Industries and Businesses) STD-T67 standard. By specific low-power wireless communication, transmission is continuously performed at predetermined time intervals. The locator terminal 200 does not turn on the light emitting element 202 and does not sound the buzzer 214 when no abnormality is caused only by the operation of the vibration switch 212. When the locator terminal 200 detects vibration even once, the locator terminal 200 transmits the terminal transmission data a predetermined number of times at a predetermined time interval, for example, twice at a 3-second interval. At this time, the locator terminal 200 has a set transmission time interval in order to avoid data collision caused by a plurality of locator terminals 200 transmitting terminal transmission data including pulse waves all at once. It is desirable to diffuse about ± 50%. The setting of the identifier information, the transmission time interval, the number of transmissions, and the like of the locator terminal 200 is performed and set via the setting machine 300 connected to a personal computer provided in the regional control facility 12. The various types of information are stored in a memory (not shown) so as to be readable by the control circuit 211. Specifically, in the monitoring system, for example, as shown in FIG. 6, the locator terminal 200 receives the setting signal transmitted from the setting machine 300 via the LF coil 216 and the LF circuit 217, and receives the received information. When stored in the memory, various information is set by transmitting a response signal to the setting device 300 via the specific low power transmission circuit 215. The locator terminal 200 does not store any personal information of the child SC in addition to the identifier information. In the monitoring system, the locator terminal 200 is associated with the child SC. It will be performed by the database provided in.

  In addition, the locator terminal 200 is controlled under the control of the control circuit 211 as shown in FIG. 7 in response to the push button 201 being pressed by the child SC for a predetermined time of, for example, about 1 second when an abnormality occurs. Further, after the buzzer 214 is sounded for a short time of about 250 milliseconds, for example, the light emitting element 202 is blinked at a predetermined time interval of about 100 milliseconds, for example. Further, the locator terminal 200 is a terminal that includes, under the control of the control circuit 211, blinking operation of the light emitting element 202, identifier information unique to the locator terminal 200, and firing information indicating that an abnormality has occurred. The machine transmission data is continuously transmitted at predetermined time intervals by, for example, specific low power wireless communication in the 426 MHz band via the specific low power transmission circuit 215. For example, the locator terminal 200 repeats the operation of transmitting the terminal transmission data for 40 seconds at intervals of 1 second and then providing a pause time of about 2 seconds. Also at this time, the locator terminal 200 sets a transmission time interval that is set in order to avoid data collision caused by a plurality of locator terminals 200 transmitting terminal transmission data consisting of pulse waves all at once. It is desirable to diffuse about ± 50% of the above. It should be noted that such a firing operation of the locator terminal 200 cannot be stopped at all by the operation of the locator terminal 200, and is stationed at the setting machine 300 or the regional control facility 12 provided in the regional control facility 12. This is performed using a report stop device 400 possessed by a guard who is on board the patrol vehicle 13, a guard on board the patrol vehicle 13, or a guardian of the child SC. Specifically, in the monitoring system, when the predetermined button provided on the notification stop machine 400 is pressed while the locator terminal 200 and the notification stop machine 400 are close to each other, the notification stop is performed. When the locator terminal 200 receives the notification stop signal transmitted from the machine 400 via the LF coil 216 and the LF circuit 217, the firing operation can be stopped.

  The locator terminal 200 is driven based on power supplied from a predetermined battery. Therefore, the locator terminal 200 has a function of obliging to replace the battery at a predetermined timing such as a new semester and notifying the battery life. Specifically, for example, as shown in FIG. 8, the locator terminal 200 detects vibrations via the vibration switch 212 and transmits terminal transmission data to reduce battery consumption. Only when the battery voltage is measured under the control of the control circuit 211 and the measured voltage is less than or equal to the predetermined voltage, the battery is continuously used until there is no remaining battery charge or a new battery is replaced. The buzzer 214 is sounded to notify that the battery is exhausted.

In such a monitoring system in which a wireless LAN using the communication device 100 and the locator terminal 200 is constructed, an IC (Integrated) that is uniquely given to the child SC when the child SC leaves the home when attending school. Circuit) card, for example, so-called RFID (Radio)
The authentication operation is performed by reading information recorded on the IC card in which the non-contact type transponder in the (Frequency Identification System) is incorporated using a predetermined reader device provided in the home. In response to this, the regional control facility 12 performs an authentication process based on the information transmitted from the reader device, and when it is determined to be valid, a user such as a school staff or a guardian of the child SC. Is notified to the mobile communication terminal owned by the instructor in the form of e-mail or the like that the child SC has been authenticated and that the child SC has started attending school. In addition, the school staff can log in to a predetermined website provided by the security company via a personal computer or the like provided at the school, thereby confirming the start of school attendance or arrival at school in almost real time. It can also be confirmed.

  In addition, in the monitoring system, every time the child SC walks during school, terminal transmission data including identifier information unique to the locator terminal 200 is transmitted from the locator terminal 200 to the nearest communication device 100. Sent. When receiving the terminal transmission data, the communication device 100 adds identifier information unique to the communication device 100 and current time information indicating the current time to the terminal transmission data. In the monitoring system, the communication device transmission data generated by the communication device 100 is transmitted to the regional control facility 12 by routing using the wireless network. Accordingly, in the monitoring system, the regional control facility 12 converts the identifier information of the locator terminal 200, the identifier information of the communication device 100 that has received the terminal transmission data, and the time information at which the terminal transmission data has been received. Based on this, it is possible to reliably grasp which child SC has passed through which point. In the monitoring system, when the child SC fires by operating the push button 201 of the locator terminal 200, the terminal transmission data including the firing information having a pattern different from the normal time is the nearest communication. The communication device transmission data generated by adding the identifier information unique to the received communication device 100 and the current time information indicating the current time to the terminal transmission data transmitted to the device 100 is the regional control facility. 12 is transmitted. Thereby, in the monitoring system, the regional control facility 12 can quickly and reliably recognize that an abnormality has occurred in the child SC possessing the locator terminal 200, the abnormality occurrence site, and the abnormality occurrence time.

  Furthermore, in the monitoring system, when leaving the school, when the child SC leaves the school, it is recorded on an IC card that is uniquely given to the child SC, for example, an IC card incorporating a non-contact type transponder in RFID. An authentication operation is performed by reading the information using a predetermined reader device provided in the school. In response to this, the regional control facility 12 performs an authentication process based on the information transmitted from the reader device, and when it is determined to be valid, a user such as a school staff or a guardian of the child SC. Is notified to the mobile communication terminal possessed by the child in the form of e-mail or the like that the child SC has been authenticated and that the child SC has started leaving the school. Even in this case, the school staff can log in to a predetermined website provided by the security company via a personal computer provided at the school, and check whether or not the child SC has started school or arrived at home. It can also be confirmed in substantially real time.

  Thus, there has never been an example in which a security company constructs a monitoring-specific wireless LAN for each region. By constructing such a wireless LAN in a monitoring system, it is possible to use a mixture of wireless sensors or wired sensors in a broadband or narrowband environment, and automatic reporting, remote monitoring, and other high added value Service can be provided.

  As described above, in the monitoring system shown as the embodiment of the present invention, the regional control facility 12 is arranged for each monitoring area, the patrol vehicle 13 is patroled, and the entire monitoring area via the communication device 100 is further arranged. By constructing a wide range of wireless LANs, it is possible to establish a very high density monitoring system that has never existed before. Therefore, in the surveillance system, it is possible to give the criminal the recognition that “this area is protected by a high-level surveillance system”, and the crime prevention effect can be greatly improved.

  In addition, in the monitoring system, the local control facility 12 is provided by having the child SC attending school attend the locator terminal 200 and continuously transmitting radio signals from the locator terminal 200 to the communication device 100. However, it is possible to ascertain which child SC passed when and where, and when an abnormal situation occurred in a child SC going to and from school, terminal transmission data including firing information was received. The radio wave reachable range of the communication apparatus 100 can be specified as the occurrence site of the abnormal situation, and the fact that the abnormality has occurred, the abnormality occurrence site and the abnormality occurrence time can be quickly and reliably recognized. In the surveillance system, by constructing such an infrastructure using a wireless LAN in the city, the line usage fee does not increase as in the case of the existing GPS-based location determination technology, and the cost is extremely low. In addition, the position of the child SC can be monitored in detail in a small area unit of the radio wave coverage of one communication device 100. Further, in the monitoring system, by providing an inexpensive line using a dedicated wireless LAN, it is possible to improve security regarding data transmission / reception and to perform reliable communication by stabilizing the bandwidth.

  Furthermore, this monitoring system arranges a regional control facility 12 and a patrol vehicle 13 that perform monitoring control for each monitoring area having a predetermined area, and when an abnormal situation occurs in a child SC going to and from school. Since the radio wave reachable range of the communication apparatus 100 that has received the terminal transmission data including the firing information can be specified as the occurrence site of the abnormal situation, the traveling vehicle 13 can quickly rush to the occurrence site, Comprehensive monitoring can be performed for the monitoring area.

  The present invention is not limited to the embodiment described above. For example, in the above-described embodiment, it has been described that a non-contact type IC card for personal authentication is used as an authentication method for a child SC. However, the present invention can be applied to, for example, retinal authentication, voiceprint authentication, You may make it authenticate by the biometrics using the physical characteristic and characteristic of the said child SC, such as fingerprint authentication, blood vessel authentication, palm authentication, human phase authentication, and handwriting authentication.

  In the above-described embodiment, the monitoring target is a school, and the child SC attending the school is monitored as the monitored object. However, the present invention is used when monitoring a student attending a cram school or the like. For example, commercial facilities, business establishments, residences, and other various facilities may be monitored, and people belonging to the monitoring target may be monitored.

  Further, in the above-described embodiment, the case where the child SC that is going to and from school is monitored as the monitored object has been described. However, the present invention is not limited to a human other than the child SC such as an elderly person, but also an animal such as a pet. , Vending machines and cash settlement machines installed in the city, vehicles parked and parked outdoors, motorcycles, bicycles, ships parked at ports, personal computers and safes installed indoors It can also be applied to any other items such as other valuables, cultural assets such as Buddha statues that are enshrined in certain buildings. For example, in the monitoring system, when the monitored object is a human being or an animal, as described above, the human being possesses the locator terminal 200 and detects the vibration due to behavior such as walking. The machine transmission data may be transmitted. On the other hand, in the monitoring system, when the monitored object is an article, the locator terminal 200 may be incorporated. However, in the monitoring system, when the monitored object is an article, it is normally left stationary, so unlike the case where the monitored object is a human being or an animal, when vibration or the like is not detected. A locator terminal 200 that transmits terminal transmission data and switches to transmission of terminal transmission data including firing information triggered by detection of vibration generated in the locator terminal 200 when the article is moved. Will be built in.

  Thus, it goes without saying that the present invention can be modified as appropriate without departing from the spirit of the present invention.
