摘要
GSM-R/CTCS的CTCS4级标准是一种基于移动闭塞系统和无线通信的列车控制系统,该标准的实施能够缩短列车之间的追踪间隔距离,提高区间通过能力,适合各种类型、各种速度的列车使用,其中无线通信是关键技术。考虑GSM-R出现的通信问题,给出Petri网表示的列车与地面设备无线通信模型和系统行为描述。
CTCS Level 4 standard of GSM/CTCS is for the train control and management based on moving blocks and wireless communication in China. Its realization can greatly reduce the distances between trains, improve the throughout of railroads, and be suitable for the trains with different types and speeds. In the whole architecture, wireless communication plays an important role for the system＇s normal and reliable operation. The model, which is described by Petri nets, is given for specifying and verifying wireless communication mode between trains and ground devices, and is very useful to ensure the reliability and robustness of the system and find the set of adaptable parameters.
