无人值守变电站周界光电一体化安防系统设计

摘要

The existing perimeter security system of unmanned substation has the situation that detection means is sin -gle, each security technology works independent and cannot achieve linkage .This has seriously affected on the securi-ty level of unmanned substation .In view of this problem , this paper designs a linkage solutions which is combined with multiple security technologies .The system used laser fence to detect and locate the intruder , and the electronic fence as a physical means to prevent invasion , and the IP cameras are used for remote monitoring and intrusion evi-dence collection .It made the transmission of control and alarm information possible by using ZigBee sensor network in substation security system.The system realized detection, obstruction, obtain evidence, recording, alarm, remote video monitoring and other functions in perimeter intrusion , and it also achieved linkage of various security technolo-gies.This system solution has a certain role in promoting the security level of unmanned substations .%现有无人值守变电站周界安防系统存在检测手段单一，各安防技术相互独立且无法实现联动的现状，严重影响了无人值守变电站的安防水平。针对该问题设计了一种综合了多种安防技术的联动解决方案。系统使用激光围栏进行入侵检测和定位，使用电子围栏作为阻挡入侵的物理手段，使用网络摄像机实现远程监控及入侵证据采集。基于ZigBee无线传感器网络实现变电站安防系统控制及报警信息的传输。该系统实现了周界入侵的检测，阻挡，取证，记录，报警及远程视频监控等功能，并实现了多种安防技术的联动。该系统方案对提高无人值守变电站的周界安防水平有一定促进作用。
