The Structure And Design of Mass Transit Computer - Based Signal - Monitoring Systems

轨道信号微机监测网络系统是集现场总线、传感技术、计算机网络、数据处理及数据通信为一体的高可靠网络体系，是重要的轨道行车安全监督设备。本文介绍试点段轨道信号微机监测工程中广域网的组网技术以及网络系统的设计原理和结构特点。

Mass Transit computer - based singal - monitoring systems are the integrated ones with high reliability, which apply many kinds of modem technology such as field - bus, sensor techniques, computer network and data communication, and are the major safety supervision devices for mass transit. To construct a highly effective modem communication network is one of the urgent outstanding issues in the design of singal - monitoring systems. This paper presents an example of building the wide area network used for the signal - monitoring system in an experimental route section. The paper also describes the network scheme and its design principles.
