Description

  The present invention relates to a remote monitoring control system and a remote monitoring control method, and relates to, for example, automatic remote monitoring.

  Currently, a general remote monitoring control apparatus performs the following operations.

  First, when a device installed far away fails, information on the failure of the device (hereinafter simply referred to as failure information) is transmitted to the central control device via the transmission line. The failure information is displayed by a central control device (for example, a control console). Further, the central control device alerts the monitoring staff by generating a warning sound (for example, a chime sound) regarding the failure information.

  In addition, a general video information transmission apparatus starts imaging related to a display target after designation of a display target to be captured (that is, a target to be displayed on the video display apparatus), and further captures the captured image. The video is started to be transmitted. Note that if the designation of the display target to be imaged is determined in advance, the operation related to the designation of the display target can be omitted.

  Here, the configuration of the remote monitoring control apparatus and the video information transmission apparatus will be described below with reference to FIG.

  In the remote monitoring control device 5 in FIG. 3, when the electrical facility 2 fails, failure information is transmitted via the transmission line (M101).

  Then, the central control device 1 receives the failure information, and according to the failure information, the failure information is visualized and displayed on the display device 1a provided in the central control device 1, or a warning sound generating device. A warning sound related to the failure information is generated by 1b.

  On the other hand, in the video information transmission device 6 in FIG. 3, the display target (for example, the electrical equipment 2) to be imaged is designated for the imaging device (for example, the camera) 3 (M102), and the display target is specified. After setting (for example, position information and magnification) is performed, imaging is started.

  Next, the captured video is transmitted to the video display device 4 (M103).

  The video display device 4 displays the transmitted video.

  The remote monitoring control device and the video information transmission device as described above include a device that determines the imaging position of the imaging device based on the alarm content (or failure content) (hereinafter referred to as an imaging information transmission type remote monitoring control system). It is known (see, for example, Patent Document 1).

In addition, an apparatus that acquires image data related to alarm content (or failure content) from a predetermined database is also known (for example, see Patent Document 2).
