摘要当前，铁路系统中的交通控制系统和指挥系统的系统集成设备大多是微电子器件，所以必须保证室内设施和轨道交通设备的稳定性和可靠性，并且需要将各个电气设备的接地极之间的电位差减小至零。铁路系统中的贯通地线是电气设备在铁路系统中的统一接地电缆，它起着非常重要的作用，可以保证铁路系统的安全与稳定运行。然而，像桥梁隧道通过的地方的贯通地线不能埋地铺设，所以经常会被盗窃或人为的破坏，如果铁路工人不及时的发现和文护，就会对铁路行车的电气设备的性能造成巨大的影响。所以对铁路贯通地线故障的监测系统的分析有着实质性的意义。

Abstract
The railway system in the traffic control system and command system of the integrated systems are mostly microelectronic devices, so must ensure the stability and reliability of the indoor facilities and rail transportation equipment, and the need to integrate all electrical equipment connected between the ends of the earth potential difference is reduced to zero. The connecting wire in the railway system is the unified grounding cable in the railway system, which plays a very important role, and can guarantee the safe and stable operation of the railway system. However, like bridges and tunnels through the through earth wire can not be buried laying, so often by theft or vandalism, if the railway workers not timely discovery and maintenance, performance of the will of the electrical equipment of the railway caused a huge impact. So the analysis of the fault monitoring system of the railway through ground wire is of substantial significance.
The research results of cable fault monitoring at home and abroad are introduced in this paper, the analysis of ZigBee technology and GSM technology, according to the railway integrative through the development of ground is proposed based on ZigBee technology and GSM short message technology of railway through ground fault monitoring program design, selection of the chip CC2530 and TC35i chip, gives the railway through ground fault monitoring scheme of the hardware circuit design and software flow chart design and the design scheme were summary and outlook. In this paper, the design scheme based on prevention, management science, can timely and accurate measurement of the fault, and the timely to the indoor host sends a message, encountered failure to warn, thereby greatly reducing the manual inspection and maintenance times and workers work pressure.
