Description

  The present invention relates to a monitoring control device.

  In a system that performs monitoring control of a power plant, an operator uses a dedicated operation console (first console) in a cab to perform monitoring and control operations on equipment to be monitored and controlled. This control operation console is realized by a CRT or a liquid crystal display device connected to a computer constituted by a general-purpose PC or an engineering workstation in a recent system, and an operator performs a control operation using a mouse. The operator conducts monitoring and control work under the supervision of the duty manager who is the head of the operator. In other words, the operator monitors the state of the monitoring target equipment displayed on his / her own driving operation console, and performs a control operation while asking for a duty length instruction if necessary. Here, in order to check the operation status of each operator, the duty length is required to be monitored in real time by the monitor length by the monitoring console (second console). .

  As described above, the control operation status displayed on the display device of the console can be displayed in real time on the display device of other consoles. The video information is distributed by hardware and the video is distributed by software. For example, Patent Documents 1 and 2 are known as prior arts.

  The method of distributing video information by hardware uses a signal distributor to branch the video output signal to the operation console, and the split video signal is propagated by laying the video signal cable to the duty console. There is a system for distributing the video signal, or a system for distributing and displaying the branched video signal via a network by installing a dedicated signal collection device and distribution device.

  On the other hand, in the method of distributing video information by software, the display data including the movement of the mouse operation of the operator written in the screen display memory of the operation console is compressed, and the compressed data is transferred to the communication channel. There is a method in which the contents can be displayed on the monitor console of the duty length by transferring to the monitor console via the network and expanding. Recently, by using VNC (Virtual Network Computing) or the like, it can be easily realized without newly preparing special software.
