文中提出了将变电站视频监控系统与周界报警系统、消防系统和门禁系统通过全面布防、相互联动进行整合;用宽带代替2 M光纤大幅度提高传输信道的带宽,解决窄带宽引发的瓶颈问题;数字信号和视频信号在传输中的抗干扰措施。变电站视频监控系统经过这些改造,功能将更趋完善,运行更加稳定可靠,才能实现真正意义上的无人值守。
文中提齣瞭將變電站視頻鑑控繫統與週界報警繫統、消防繫統和門禁繫統通過全麵佈防、相互聯動進行整閤;用寬帶代替2 M光纖大幅度提高傳輸信道的帶寬,解決窄帶寬引髮的瓶頸問題;數字信號和視頻信號在傳輸中的抗榦擾措施。變電站視頻鑑控繫統經過這些改造,功能將更趨完善,運行更加穩定可靠,纔能實現真正意義上的無人值守。

This paper advocates integrating the substation video monitoring system with perimeter alarm system,fire fighting system and access control system through full deployment and inter-linkage,adopting broadband instead of 2M fiber to increase the bandwidth of transmission channel by a wide margin and solve the bottleneck owing to the narrow bandwidth,and the anti-interference measures of video signals and digital signal in transmission.The substation video monitoring system functions more perfectly,runs more stably and reliably,and achieves the real meaning of unattended by the reform above.
