| The transformer substation generally has "four remote" system now, always been named as the remote measure, the remote letter, the remote control and the remote regulating, which can the scend equipment performance data, the condition to the distantly control center, simultaneously the control center may also carry on the control and the adjust to the long-distance field apparatus. But taking the unattended substation only to have four remote systems is insufficient, because the control center is unable to understand the scene situation which may make some safe guards ,such as "the fire protection, security" and so on to, be unable to realize, therefore the substation still needed some people to protect day and night.Along with computer technologies, multimedia technologies and mechanics of communication rapid development, the processing technology for image, sound and multimedia signal are already quite mature, introducting this mature technical in electric power dispatch automated system, adding remote video system on the base of four remote remote system, can monitor and the surveil related data, the parameter, the image of various substations and know what occurs in the substation so as to make the response promptly.The system applies the computer technologies, multimedia technologies and advanced technologies fully, design and realize the substation long-distance supervisory system basing on communication network's, propose one kind of event triggering-like monitoring strategy. Not only may save the memory resources, but also can more conveniently and quickly withdraw useful information in the video recording, raises the working efficiency. The design meets the modular requirement and the extendibility is good, the system can gather real-time information and process dynamic image and realizes the multimedia information memories, the transmission and network sharing and so on by the way of fixed time, the warning or the remote control... |
