摘　　要：针对低压配电电缆屡屡被盗的现状,设计了基于电力线载波通信的电缆防盗系统。该系统分为发送端和接收端,分别安装在电缆的两端。发送端以固定的时间间隔持续发出载波信号,载波信号通过电缆传输,接收端接收两次发送端发出的信号超过一定的时间间隔则认为电缆已被盗剪,系统发出报警信号。电力线载波通信模块采用电力线载波Modem芯片SSC P300,单片机采用的是M68HC11E9芯片。该电缆防盗系统具有较好的应用前景。To solve the problem of serious theft of low voltage power cables, an anti-theft system based on PLC communication technology is introduced in the paper. This system is composed of a transmitter and a receiver, which are installed at two terminals of power cable. The transmitter sends out continuous carrier signals at a fixed time interval via power cable while the receiver receives the carrier signals. If the interval of the latest two signals is paranormal, an alarm signal will be made to indicate the damage of power cables. SSC P300 was used as modem chip of power line carrier communication module, and M68HC11 E9 is used as CPU. The anti-theft system has great development potentialities.
