摘要
本文分析了国内外在铁路接触网研究方面的现状,提出了一种能对铁路接触网的张力进行实时在线检测以及断线事故预警的系统。介绍了该系统的基本工作原理及ARM嵌入式微处理器和磁致伸缩式张力传感器的特点,分析了采用GPRS短信通信方式进行断线报警的原理,及定时自检的过程,对该系统进行了功耗分析,最后列出了设备清单及器件。
In this paper, the research in the railway catenary fault aspects at home and abroad is introduced. The system that can detect the railway catenary of the tension on line and real time as well as forewarn the broken line accident is proposed. It analizes the system＇s basic working principle and the characteristics of ARM embedded microprocessor and tension-magnetostrictive sensor, describes the principle of the use of GPRS communication for the break alarm and the process of self-timing, carries out a power analysis and finally introduces a list of equipment and devices.
