无人值守变电站周界联动安防系统设计

The Design of Linkage Security System of Transformer Substation

分析了变电站周界安防系统的不足,综合变电站无人值守对周界安防提出的新要求,提出一种可精准定位、基于ZigBee通信、多技术联动的安防系统。利用激光测距、超声波测距设计出新型报警定位围栏,利用ZigBee技术搭建安防系统通信层,联动网络摄像头、电子围栏、语音报警、GPRS实现抓拍取证、阻挡、报警等功能。系统实现了精准定位、减少布线、多技术联动以提高整体安防水平的目标。

Unattended substation needs new requirements for perimeter security.In view of the shortage in the security system of substation,this paper puts forward a solution including multi linkage technology,localizable function and ZigBee communication.It designs a new alarm positioning fence using laser ranging and ultrasonic rangefinder.It builds the communication layer with ZigBee technology.Thus it accomplishes the functions of forensics,obstruction,and alarm through the network camera,electronic fence,alarm and GPRS.The system achieves a precise positioning,reduces wiring,and improves the overall level of security system of the substation.
