  Next, the alarm transmission process of the abnormality detection information according to the present embodiment configured as described above will be described. FIG. 7 is a sequence diagram showing a procedure of alarm transmission processing for abnormality detection information according to the present embodiment.

  First, when the sensor 211 of the first security device 110 detects an abnormality, the first security device 110 transmits an abnormality detection information alarm to the monitoring center 130 using the Internet 140 (step S701).

  If the first security device 110 does not receive a confirmation signal indicating that an alarm has been received from the monitoring center 130 within a predetermined time, the first security device 110 transmits an alarm again to the second security device 120 using the Internet 140 ( Step S702). Here, when the confirmation signal is not received from the monitoring center 130, for example, the alarm transmitted in step S701 may not be received by the monitoring center 130 due to a network failure such as an Internet failure on the ISP side. Next, the second security device 120 that has received an alarm from the first security device 110 via the Internet 140 transfers the alarm received from the first security device 110 to the monitoring center 130 using the public line 150. (Step S703).

  Here, in the monitoring center 130, when an alarm is received from either the first security device 110 or the second security device 120, a confirmation signal indicating that the alarm has been received is sent to the first security device from which the alarm is transmitted. 110, the IP address of the second security device 120 is designated and transmitted. Therefore, the monitoring center 130 that has received the alarm from the second security device 120 transmits a confirmation signal indicating that the alarm has been received to the second security device 120 (step S704). Then, the second security device 120 transfers the confirmation signal received from the monitoring device 130 to the first security device 110 (step S705). If the monitoring center 130 receives an alarm from the second monitoring device 130 via the public line 150, the monitoring center 130 transmits a confirmation signal to the second monitoring device 130 using the public line 150.

  Next, an alarm transmission process in the first security device 110 in the entire process of alarm transmission will be described. FIG. 8 is a flowchart showing a procedure of alarm transmission processing for abnormality detection information of the first security device 110 according to the present embodiment.

  First, when the sensor 211 detects an abnormality, the abnormality reporting unit 223 transmits an abnormality detection information alarm to the monitoring center 130 using the Internet 140 (step S801). The communication processing unit 225 determines whether a confirmation signal indicating that an alarm has been received from the monitoring center 130 within a predetermined time has been received (step S802). When the communication processing unit 225 receives a confirmation signal indicating that an alarm has been received from the monitoring center 130 within a predetermined time (step S802: Yes), the alarm transmission process ends.

  On the other hand, if the communication processing unit 225 fails to receive a confirmation signal from the monitoring center 130 within a predetermined time (step S802: No), the alarm transmitted in step S801 due to a network failure such as an Internet failure on the ISP side is displayed. At 130, it is determined that it was not received. For this reason, the abnormality reporting unit 223 uses the second security guard from the IP address database 217 to send a warning to the monitoring center 130 via another security device without going through the Internet 140 where the network failure has occurred. The IP address of the device 120 is selected as the security device through which the device 120 passes (step S803).

  Further, the abnormality notifying unit 223 transmits an alarm to the second security device 120 corresponding to the selected IP address using the Internet 140 (step S804). The IP address of the second security device 120 from the IP address database 217 can be arbitrarily selected, and the security device identification information in the IP address database 217 or the IP address in ascending or descending order or randomly. IP address can be selected.

  Next, the communication processing unit 225 determines whether or not the confirmation signal from the monitoring center 130 transferred from the second security device 120 selected within the predetermined time has been received (step S805). If the communication signal is received by the communication processing unit 225 within a predetermined time (step S805: Yes), the abnormality detection information alarm transmission process ends.

  On the other hand, when the confirmation signal cannot be received within a predetermined time by the communication processing unit 225 (step S805: No), the abnormality notification unit 223 selects the IP address of the next second security device 120 (step) S806), the alarm transmission process and the confirmation signal reception confirmation in steps S804 and S805 are performed on the newly selected second security device.

  Next, alarm transmission processing by the second security device 120 will be described. FIG. 9 is a flowchart illustrating a procedure of alarm transmission processing of abnormality detection information of the second security device 120 according to the present embodiment.

  First, the receiving unit 425 receives an abnormality detection information alarm from the first security device 110 via the Internet 140 (step S901). Next, the transfer unit 426 transfers the alarm received from the first security device 110 to the monitoring center 130 using the public line 150 (step S902).

  The receiving unit 425 receives a confirmation signal indicating that an alarm has been received from the monitoring center 130 via the public line 150 (step S903), and the transfer unit 426 uses the Internet 140 for the confirmation signal received from the monitoring center 130. To the first security device 110 (step S904). As a result, even if a failure occurs in the Internet and an alarm cannot be transmitted directly from the first security device 110 to the monitoring center 130, an alarm is transmitted to the monitoring center 130 via the second security device 120. It becomes possible to do.

  In the monitoring center 130, when the communication processing unit 504 receives an alarm from either the first security device 110 or the second security device 120, a confirmation signal indicating that the alarm has been received is sent to the alarm transmission source. Processing for transmitting the IP address of the first security device 110 or the second security device 120 is performed. When the monitoring center 130 receives an alarm from the second monitoring device 130 via the public line 150, the monitoring center 130 transmits a confirmation signal to the second monitoring device 130 using the public line 150.

  In the monitoring center 130, the IP address database 505 is managed by the address management unit 502, and the addition, change, and deletion of the security device identification information and the IP address entry are requested by a request from the system manager of the monitoring center 130, etc. It is carried out.

  In addition, in the monitoring center 130, when the IP address database is changed due to addition, change, or deletion of the security device identification information and the IP address entry, the communication processing unit 503 changes the IP address database (addition). , The changed or deleted security device identification information and IP address entry) are transmitted to all the first security devices 110.

  A second change is made due to a network change between the monitoring center 130 and the second security device 120, a new security contract between the system administrator of the second security device 120 and the monitoring center 130, a contract change, a cancellation, or the like. When there is a change in the identification information or IP address of the security device 120 and the contents of the IP address database 505 are changed, the first security device 110 normally changes the contents of the IP address database 505 accompanying such a network change. I can't know. For this reason, by transmitting the change contents of the IP address database 505 from the monitoring center 130 to each first security device 110, the security device identification information and IP of the second security device 120 are transmitted on the first security device 110 side. The change of the address can be grasped, and the IP address database 217 in the first security device 110 may be updated based on the received change content. As a result, the information of the second security device 120 for transmission via the alarm can always be kept up-to-date, and the alarm is always sent to the second security device 120 when a failure occurs on the Internet. Thus, it is possible to reliably and promptly respond to abnormalities in the monitoring area.

  As described above, in the present embodiment, the first security device 110 connected only to the Internet 140 detects the abnormality by the sensor 211 and transmits an abnormality detection information alarm to the monitoring center 130 within a predetermined time. If the confirmation signal indicating that the alarm is received from the monitoring center 130 is not received, the alarm is transmitted again to the second security device 120 connected to the Internet 140 and the public line 150 other than the Internet 140. do. Then, the second security device 120 transfers the received alarm to the monitoring center 130 using the public line 150 other than the Internet 140, and the monitoring center 130 that has received the alarm transmits a confirmation signal to the second security device 120. Then, the second security device 120 transfers the received confirmation signal to the first security device 110. For this reason, even if the first security device 110 connected to the monitoring center 130 only through the Internet 140 cannot transmit an alarm to the monitoring center 130 due to a failure in the Internet 140, the other than the Internet 140 An alarm can be transmitted to the monitoring center 130 by the second security device 120 connected also through the public line 150, and a confirmation signal from the monitoring center 130 can be received by the first security device 110. Therefore, even if a failure occurs in the Internet 140, it is possible to quickly respond to an abnormality in the monitoring area and to notify the first security device 110 that an alarm has been received.
