When the camera device 110 of the camera terminal station 100 is supplied with power from the backup power supply unit 126, the camera terminal name is displayed in red. When the camera devices 110 of the two camera terminal stations 100 are supplied with power from the backup power supply unit 126, the corresponding camera terminal name of the camera terminal station 100 is displayed in red and displayed on the monitor 204. The area (section) between these camera terminals on the map on the screen is displayed in red or the like as in area 1 (indicated by hatched area 1) in FIG. When power is supplied from the backup power supply unit 126 to the camera devices 110 of a plurality of camera terminal stations 100 in three or more places, the area 2 in FIG. (Shown) is determined to have a power outage, and the corresponding area is displayed in red or the like.

  FIG. 3 is a flowchart showing the flow of the power failure monitoring process executed by the power failure monitoring processing unit 207 of the management server 205. The power failure monitoring process will be described based on the order of steps shown in the flowchart of FIG. When the management server 205 inputs power supply switching information from the LAN-SW 202, the management server 205 outputs the power supply switching information to the power failure monitoring processing unit 207. The power failure monitoring processing unit 207 inputs power supply switching information and starts a power failure monitoring process.

  First, the power failure monitoring processing unit 207 extracts the camera terminal station name from the input power supply switching information (step S101).

  The power failure monitoring processing unit 207 sets an initial value 1 to the extraction index (I) for extracting the camera terminal station name from the camera terminal station information table shown in FIG. 4 (step S102).

  The power failure monitoring processing unit 207 determines whether the camera terminal name stored in the I-th position in the camera terminal information table is equal to the camera terminal name of the power source switched this time taken out in step S101. When the camera terminal station names are equal, the process proceeds to S106 for storing the power failure determination flag in the camera terminal station information table. If the camera terminal station names are not equal, the process proceeds to step S104 for updating the take-out index (I) of the camera terminal station information table (step S103).

  The power failure monitoring processing unit 207 updates the extraction index (I) by adding 1 to the extraction index (I) in order to extract the name of the next camera terminal from the camera terminal information table (step S104).

  In order to check whether the power failure monitoring processing unit 207 has determined all the camera terminal names in the camera terminal information table, the take-out index (I) and the stored number n of the camera terminal names in the camera terminal information table are stored. Compare. If the retrieval index (I) is larger than the stored number n, the power failure monitoring processing unit 207 completes the power failure monitoring process because the check is completed for all camera terminal station names in the camera terminal information table. On the other hand, if the retrieval index (I) is less than or equal to the stored number n, the process returns to step S103 for comparison with the next camera terminal name in the camera terminal information table (step S105).

  The power failure monitoring processing unit 207 takes out the switched power source (normal power source or backup power source) from the power source switching information, and stores the switched power source in the power failure determination flag of the camera terminal station information table. For example, when the power supply of the camera terminal name “bba” of No (i) in the camera terminal information table shown in FIG. 4 is switched from the normal power supply unit 125 to the backup power supply unit 126, the camera in the camera terminal information table The power failure determination flag corresponding to the terminal station name “bba” is changed from the regular power supply “0” to the backup power supply “1” and stored (step S106).

  The power failure monitoring processing unit 207 changes the color of the camera terminal station name in the power failure monitoring diagram shown in FIG. 2 to a corresponding color based on the power failure determination flag of the camera terminal information table. For example, when the power failure determination flag corresponding to the camera terminal name “bba” of No (i) in the camera terminal information table is changed from the regular power supply “0” to the backup power supply “1”, the camera terminal name “ bba "is displayed in red (step S107).

  The power failure monitoring processing unit 207 determines whether there are a plurality of camera terminals whose stop determination flag is “1” (step S108). If there are a plurality of camera terminals whose stop determination flag is “1” (Yes in step S108), the process proceeds to step 109 where the color of the area corresponding to the inside of the calculated polygon in the power failure monitoring diagram is changed to red. . Further, when there are one or less camera terminal stations with the stop determination flag “1”, the power failure monitoring processing unit 207 determines that only the camera terminal station is a single power outage (internal of the camera terminal station). The process proceeds to step S110 without specifying a specific area (No in step S108).

  When there are a plurality of camera terminal stations with the stop determination flag “1”, the power failure monitoring processing unit 207 uses the position where the camera terminal station with the stop determination flag “1” is installed as the vertex of the polygon. The polygon is calculated, the area is determined to be a power failure, and the color of the area corresponding to the calculated polygon in the power failure monitoring diagram is changed to red (step 109). For example, since the stop determination flags of No2, No (i), and No (i + 2) in the camera terminal information table shown in FIG. 3 are all stored as “1” as the backup power source, the camera terminal “aab” of No2 is stored. , The area surrounded by the camera terminal “bba” of No (i) and the camera terminal “bbc” of No (i + 2) is determined as a power failure. Therefore, areas 1 and 2 in the power failure monitoring diagram shown in FIG. 2 are displayed in red (step S109), and then the process proceeds to step S110.

  The power failure monitoring processing unit 207 displays the rewritten power failure monitoring diagram on the monitor 204, and ends the power failure monitoring processing (step S110).

  In the embodiment of the present invention, the example in which the area determined to be a power failure is displayed in a polygonal shape. However, the present invention is not limited to this, and when there is a presumed range, the corresponding range is displayed in red according to the map. May be. Alternatively, roads and rivers in that range may be displayed in red. In the embodiment of the present invention, the CCTV facility and the power outage area where a power outage has occurred are displayed in red, but the display color is not limited to red.

  According to such an embodiment, a power failure monitoring system and a power failure monitoring method capable of monitoring whether the section where the CCTV facility is installed has a power failure by monitoring the power supplied to the CCTV facility. Can provide.
