摘要
介绍了一种基于电力载波技术和模数转换器TLC3548的路灯电缆防盗报警器的硬件和软件设计实现方案。阐述了该方案的原理,即在主机与从机间进行电力载波通信以检测电缆状况,通过单片机控制TLC3548进行数据采集与分析,比较精确地测量出断缆处距路灯现场控制柜的距离,并将信息经GPRS通信模块上报给服务器。经实验证明,该防盗报警器可靠实用,性价比较高。
The paper introduces the hardware and software design program of burglar alarm for street lamp electric cable, which based on the technique of power line communication and analog-to-digital device TLC3548. And also it explaintes on the theory of program, which communicated by power line carrier to detect cable status between master and slaver. Then the design through MCU controlls TLC3548 to sample and analyze the data. According to the method, the system can measure the distance from distribution cabinet to broken cable. Thus alarm reported information to the server by GPRS module. The practice showes that the burglar alarm is reliable , practical and high cost-effective.
