摘　　要：针对广深准高速铁路信号设备的实时监测,开发研制了采用PLC为采集机的GSWJ 98型微机监测系统;该系统的转辙机动作电流监测回路,通过转辙机动作电流监测铁路线上的重要设备道岔的运行状态,为设备的维护和检修提供依据,保证准高速路列车行驶安全.从硬件、软件两个方面分析了转辙机监测回路的原理及实现.Railway status microcomputer monitoring system is used for monitoring the running status of all equipments in the railway in real time. For the Guang-Shen high-speed railway, we develop the GSWJ-98 microcomputer monitoring system. In the system, we use the running current curve of the pointer to record and inspect the status of turnout; it is very important in railway. Furthermore, the record help to examine and repair the equipments, as well as to assure the safe running of the train. This paper demonstrates the theory and implement of the pointer's monitoring circuit.
