(2) Operation / Action FIG. 3 is a functional block diagram of the security system 1 mainly composed of the personal terminal 2. FIG. 4 is a flowchart for explaining the location management method according to the present embodiment. Of the reference numerals shown in the figure, elements having the same reference numerals as those described above represent the same elements.

  In the security system 1 having such a configuration, a person passing through the gate device 6 is given a personal terminal 2 by a security officer or the like. In step A1, the security system 1 uses the terminal information that identifies the personal terminal 2 and the area information that the personal terminal 2 is permitted to enter as a personal terminal data database by an operation by a security officer or the function of the gate device 6. 7 is registered.

  In step A2, the personal terminal 2 performs outdoor positioning or indoor positioning. When the personal terminal 2 is moving outside the site where the gate device 6 is connected, outside the facility or outside the building, the nearest base station 11 communicates with the personal terminal 2 through the control channel, and the personal terminal 2 receives the GPS positioning information.

  In step A3, the management server 15 collates the received position information with information registered in the database 7 in advance. As an example, the collation processing is performed as follows. In the outdoors, a security officer inputs individual name information and time zone information of a site, a facility, and a building to the management terminal 15a, and determines whether or not the records match the records in the database 7. Images from surveillance cameras 8 provided outside the site, facility, and building are displayed on a monitor 9 for verification.

  If there is no abnormality in step A3, the route passes “OK” and the management server 15 determines in step A4 that the alarm output is not necessary, and the process ends. By registering the terminal information of the personal terminal 2 in the database 7 in advance, the specific personal terminal 2 is permitted to enter. The security officer confirms that the terminal information is entered into the building with the terminal information by outdoor positioning, and confirms that the person having the personal terminal 2 has entered the building with an image and a detection signal. The same is true indoors.

  If an abnormality is detected in step A3, the management server 15 passes the route labeled “NG”, and in step A5, the management server 15 tells the indoor wireless transmission / reception device 18 that the person has entered the non-permitted area. An alarm message is transmitted to the terminal 2. When a person who is allowed to enter the outdoor area disappears from the video, an alarm is output as an abnormal movement is detected. The same judgment is made both indoors and outdoors.

  If an abnormality is detected in step A3, the route passes “NG”, and in step A6, the management server 15 detects illegal intrusion to the security server verification server 9 or extension telephone. Notify the alarm message. Although a person is passing by outdoors in the video, when the result of positioning information obtained by outdoor positioning is viewed, it is detected that the information is not registered. The same judgment is made both indoors and outdoors.

  Therefore, the position information of the personal terminal 2 in the monitoring target area can be obtained seamlessly outdoors and indoors, and the position management of the target person can be performed based on the movement destination of the personal terminal 2 registered in advance.

  As described above, the security system 1 causes the employee to hold the personal terminal 2, performs positioning by the GPS satellite 10 outdoors, and transmits the result via the mobile communication network 12. In the indoor 16, positioning is performed by the indoor positioning system 5, and the result is transmitted from each personal terminal 2 and received by the indoor wireless transmission / reception device 18. The management server 15 collates the received position information with information registered in the personal terminal 2 in advance, and if there is a person in an area where it is not permitted, a signal such as an alarm is sent from the indoor wireless transceiver 18 to the individual. For example, it is transmitted to the terminal 2. By issuing a warning such as an alarm, it is possible to prevent accompanying persons from escaping from the security system 1 in and out of the room.

  In addition, the management terminal 15a checks whether the person shown in the video of the monitoring camera 8 monitored in the security room has the personal terminal 2, and manages crime prevention for suspicious persons who do not have the terminal. Can be done. In this way, security monitoring can be performed on the premises of the company.

  For example, as the personal terminal 2 moves indoors from the outside, the display board 15b of the management server 15 indicates that the personal terminal 2 having the terminal ID “A” is in the conference room indoors and that the same personal terminal 2 is outdoor. Being in “B town” can be displayed on the screen without interruption both indoors and outdoors. The security system 1 can seamlessly collect information of the personal terminal 2 to be monitored between outdoors and indoors.

(Modification)
In the above description, the intruder detection is an example, but the location management method according to the modification of the first embodiment of the present invention can be used in the work management system. For employees who are often on the road, the personal terminal 2 having a function capable of positioning both indoors and outdoors is provided in advance, and the system is operated in the same manner as in the above example.

  Referring to the flowchart of FIG. 4, in step A3, the management server 15 collates the position information from the personal terminal 2 carried by the employee with the work schedule information of this employee registered in the database 7 in advance. To do. In step A7, if the terminal position matches the outdoor position or indoor position described in the work schedule, a history is recorded in the work management system.

  According to this modification, attendance management can be performed by using the mobile communication network 12 which is a communication network of a mobile communication carrier. Can be used like a time card.
