CSD模式下无线列调信息传输方式的研究

介绍一种利用GSM-R系统电路交换数据模式来传输无线列车调度数据的方式,具有可靠性高、传输时延小和安全性好的优点。因此建立一个基于GSM-R网络CSD模式的列车调度信息传输系统,实现调度中心和列车之间传送无线列调数据信息,并就CSD模式的数据传输可靠性、安全性和实时性问题进行分析。

A method of data transmission in radio train dispatching system is introduced. This method is based on circuit switch data mode of GSM-R system and it has some particular features, such as higher reliability, lower transmission delay and better security. So, a train dispatching information system based on CSD mode of GSM-R system is built and it can transfer dispatching data information between the control center and trains. The reliability, security and realtimeness of the system are also analyzed.
