摘要
结合非接触式人体感应探测、无线传输技术,介绍一种基于GPRS的电力行业变电设备防盗系统组网及设计架构,包括自适应人体感应探测器原理设计、GPRS数据终端设备的通信机理及多点并发数据防冲撞技术方案、供电自动切换电路及系统软件功能的设计与实现等。系统集智能化、高可靠性及布防便捷于一体,可以解决电力设施经常被盗的难题。
Combining with the untouched human-body detection sensor and wireless commumcatlon technology, a design and network architecture of electric power equipment guard against theft and alarm system based on General Packet Radio Service（GPRS） was introduced. It included the design of the self-adaptive human-body detection sensor, the communication method of GPRS-Data Terminal Unit（DTU）, the solution of anti-collision technology about multi-point concurrent data, the realization of the power supply automatically switching circuit, the design and implementation of the system software functions, etc. The system was integrated with intelligence, high reliability and easy deployment. It can solve the problem of electricity installations guard against theft and will be very popular for power industry.
