  The wireless communication unit 21 of the wireless communication unit 20 includes a plurality (1 to n) of wireless communication units 1 to n, which are appropriately selected and wirelessly connected to a plurality of mobile wireless terminals. The base station is connected to a line via a communication line 80 and a public communication network 70 to establish communication between a plurality of mobile radio terminals. Furthermore, it is connected to a management center (not shown) via the communication line 80 and the operation state is monitored. As the communication line 80, a dedicated communication line depending on the anti-theft system may be used, or a public communication line such as the Internet may be used. The power supply means 22 supplies power supplied from a connected AC power source to each unit and charges a built-in battery (not shown). When the power supply from the AC power supply is cut off, the radio base station 10 switches to the battery power supply, and an AC power supply cut-off signal that informs the interruption of the power supply from the AC power supply is sent to the operating state detection means 30.

  The operating state detection unit 30 is connected to the wireless communication unit 21 of the wireless communication unit 20 and monitors the communication state with the public communication network 70. When it is detected that the communication line 80 is disconnected due to this communication state and an AC power cut-off signal is received, it is determined that the operation is abnormal, and the operation abnormality signal is sent to the position information detection means 40. The position information detection means 40 receives the operation abnormality signal, detects the position information of the radio base station 10, and sends it to the theft determination means 50 and the theft countermeasure means 60. The location information detection means 40 acquires (detects) location information of the base station 10 using the GPS radio unit 23 that is installed and used by the radio base station 10 to synchronize with other base stations. ing.

  The theft determination means 50 compares the acquired position information with a predetermined position of the wireless base station 10 set in advance, and determines that the theft is not in the stolen state when both are substantially the same. If they are different, it is determined that the theft is in a stolen state, and a theft determination signal is sent to the theft countermeasure means 60. The theft response means 60 receives the position information and the theft determination signal and issues an alarm by the alarm means 63, or transmits at least one of the position tracking information and the theft signal from the position pursuit means 61 and the information notification means 62 to the wireless communication unit 21. Send to. The radio communication unit 21 communicates these signals and information to another radio base station by any one of the radio communication units 1 to n, and transmits the signal and information to the management center via the other base station and the public communication network 70. Even if it is not determined that the theft is determined by the theft determination means 50, the operation state detected by the operation state detection means 30 is similarly transmitted by any one of the wireless communication units 1 to n to the management center. You may make it transmit.

  FIG. 2 is a block diagram showing the configuration of the anti-theft system of the present invention. In the anti-theft system 100, a group of radio base stations composed of a plurality of radio base stations 10a to 10n is connected to a public communication network 70 via a communication line 80, and is connected to a management center 90 via the public communication network 70. Connected to the entire system. A plurality of radio base stations 10a to 10n constituting a group of radio base stations are wirelessly connected to a plurality of mobile radio terminals, and are connected to each other via a communication line 80 and a public communication network 70 to be connected between the plurality of mobile radio terminals. Has been established. The management center 90 is connected to each of the plurality of radio base station groups 10a to 10n via the communication line 80, and monitors the operation status of each.

  In the wireless base station group of FIG. 2, the case where the wireless base station 10b is in a stolen state will be described with reference back to FIG. Due to theft, the communication cable of the communication line 80b connected to the radio base station 10b and the AC power cable connected to the power supply means 22 are disconnected. The power supply means 22 switches to a battery power supply when the AC power is cut off, and sends an AC power cut-off signal to the operating state detection means 30.

  When the operation state detection unit 30 detects that the communication line 80b is disconnected and receives the AC power cut-off signal, the operation state detection unit 30 determines that the operation is abnormal and sends the operation abnormality signal to the position information detection unit 40. When receiving the operation abnormality signal, the position information detection unit 40 detects the position information of the radio base station 10 b and sends the detected position information to the theft determination unit 50 and the theft countermeasure unit 60. The theft determination means 50 compares a predetermined position of the radio base station 10b set in advance with the received position information, and if different, determines that the theft is in a stolen state and sends the theft determination signal to the theft response means 60. send.

  When receiving the theft determination signal, the theft countermeasure means 60 causes the position pursuit means 61 to pursue the position of the radio base station 10b, and uses the data (position information of the radio base station 10b detected by the position information detection means 40). The information is sent to the wireless communication means 21 or the information notification means 62 is instructed to send theft information. For example, the theft information may be communicated first, and the location tracking information may be subsequently transmitted. When receiving this instruction, the information notification unit 62 transmits a theft signal to the wireless communication unit 21, and the position pursuit unit 61 continuously receives the position information from the position information detection unit 40, and the position tracking data Is transmitted to the wireless communication unit 21. The wireless communication unit 21 transmits the received theft signal or location tracking data to a surrounding wireless base station (for example, the base station 10 c), and transmits the received data to the management center 70 via the base station and the public communication network 70. Further, when the position information of the position information detecting means 40 is no longer detected, the alarm means 63 of the theft handling means 60 issues an alarm and informs the surroundings that it is in a stolen state. This is because tracking information cannot be obtained unless position information is detected, and further movement of the radio station 10 can be suppressed by informing the surroundings. Note that an alarm may be issued when it is determined that the device is stolen.

  Returning to FIG. 2 again, a process in which the wireless communication unit 21 transmits a theft signal or location tracking data to the management center 70 will be described. The radio base station 10b in the radio base station group is in a stolen state, and the communication line 80b is disconnected. Therefore, the wireless base station 10b establishes wireless communication with a neighboring base station within the reach of the radio wave in order to transmit the received theft signal or position tracking data to the management center 90. For example, when wireless communication is established with the wireless base station 10 c in the wireless base station group, the wireless base station 10 c transmits the received theft signal or position tracking data to the management center 90 via the communication line 80 c and the public communication network 70. To do. The management center 90 receives this, contacts the jurisdiction based on the position tracking data, and can respond quickly. If there is a move or relocation due to maintenance or the like, the theft mode is canceled from the management center 90 in advance according to the schedule, or the theft mode determination unit 50 of the radio base station 10 is directly operated to cancel the theft mode according to the schedule. .

  The hardware configuration shown in FIGS. 1 and 2 may be any circuit or device as long as it is a means for realizing the function, and a part of the function can be realized by software. . Furthermore, the function realizing means may be realized by a plurality of circuits, and a plurality of functions may be realized by a single circuit.

  FIG. 3 is a flowchart showing a processing flow of the anti-theft system for equipment according to the present invention. Since the wireless base station 10 in the operating state is stolen, the AC power cable connected to the power supply means 22 and the communication cable of the communication line 80 are disconnected (step 100 to step 120). When the operation state detection unit 30 detects that the communication line 80 is disconnected and receives an AC power cut-off signal, the operation state detection unit 30 determines that the operation is abnormal and sends the operation abnormality signal to the position information detection unit 40 (step 130). When the position information detection means 40 receives the operation abnormality signal, the position information detection means 40 detects the position of the radio base station 10 and sends the detected position information to the theft determination means 50 and the theft response means 60 (step 140). The theft determination means 50 compares a predetermined position of the wireless base station 10 set in advance with the received position information, and if it is different, determines that the theft is in a stolen state and sends a theft determination signal to the theft response means 60. Send (step 150).

  The alarm means 63 of the theft response means 60 is unable to obtain tracking information when the position information of the position information detection means 40 is no longer detected, and therefore issues an alarm to inform the surroundings that the device is in a stolen state and terminates (step 160, Step 170, Step 220). When the position information is continuously detected, the theft countermeasure means 60, when receiving the theft determination signal, pursues the position of the radio base station 10 to the position pursuit means 61 and sends the data to the radio communication unit 21. Alternatively, the information notification means 62 is instructed to transmit theft information (step 160, step 180). When wireless communication is established with, for example, the wireless base station 10c in the wireless base station group of the peripheral base stations, the wireless base station 10c manages the received theft signal and position tracking data via the communication line 80c and the public communication network 70. It transmits to the center 90 (step 190, step 200). The management center 90 receives this, contacts the jurisdiction based on the position tracking data, and finishes with a quick response (step 210, step 220).

  As described above, a special theft detection sensor is installed by detecting the position of the radio base station 10 by the GPS used to detect the AC power cable or the communication line cable disconnection and to synchronize. Since it is not necessary, it is possible to provide an inexpensive and compact anti-theft system for equipment without accompanying a large apparatus burden. In the above-described embodiment, an example in which the present invention is applied to a radio base station has been described. However, the present invention can also be applied to other device apparatuses.
