摘　　要：高速公路电力电缆的被盗不仅直接对电力部门造成一定的经济损失,而且会对公路安全和人民的生命安全构成严重的威胁。而高速公路电缆防盗报警系统设计和研制的核心问题之一就是断缆信号的检测问题。本文主要阐述了目前电缆防盗报警系统设计中常用的信号检测方法,通过比较各种信号检测方法在实际应用中的优缺点,提出了在高速公路电缆防盗报警系统设计中最具发展潜力的信号检测方法是电力线载波通信法,并对电力线载波通信技术的国内外研究现状进行了介绍。最后对高速公路电缆防盗报警系统信号检测方法的发展趋势进行了简要的分析。The theft of power cables on highway directly bring about extent economic losses for electricity sector, while it pose a serious threat for road safety and the safety of the lives of the people. One of the core issues of design and development on hignway cable burglar alarm system the broken cable signal detection. This paper describes the current commonly signal detection method used in the power cable burglar alarm system. By comparing the various detection methods in the practical application of the advantages and disadvantages, Raised the most development potential of the signal detection method is the power line carrier communication method on the highway cable burglar alarm system design. And introduce the status of power line carrier communication technologies at home and abroad. Finally, this paper has carried on the brief analysis to its trend of development.
