摘要
通过对深圳地铁一期信号数据传输系统的分析,从中央设备层、中间传输层及现场设备层逐一介绍其工作原理及设备特点。信号系统通过802.3、OTN、Profibus等通信协议使中央控制中心与现场设备大量的数据交换成为可能,分布性、可靠性与扩展性都得到了极大的提高。
The working principles and equipment characteristics of central equipment level, middle transmission level and field equipment level are introduced by analyzing the signal data transmission system of Shenzhen Metro Stage 1. The signal system makes the massive data exchange between central control center and field equipment possible by using communication protocols, such as 802.3, OTN and Profibus. The distributivity, reliability and expansibility have been improved greatly.
