Through analyzing the existing problems of the monitoring and command of the original railway communication work, this paper expounds the functions of hand-held mobile monitoring positioning terminal to show that the application of monitor terminal system in railway communication system plays an important role in improving the emergency rescue of railway communication and the control of construction work and protecting the operation security of railway communication. The application of terminal greatly improves the working accuracy, shortens the time of failure treatment, reduces the economic losses caused by the faults and greatly improves the efficiency of railway communication. It is helpful to achieve the goal of value management.%本文通过分析原有铁路通信作业监控指挥存在的问题，阐述手持移动监控定位终端的功能，进而说明在铁路通信系统中应用监控终端系统，在改进铁路通信应急抢险和施工作业把控及铁路通信作业安全保障方面发挥的重要作用。终端的使用大大提高了作业精度，缩短了处理故障的时间，降低了故障造成的经济损失，从而大大提高铁路通信的效率，有助于实现价值管理的目标。
