基于GPRS网络的无线通信接口单元分析与研究
Analysis and Research on Wireless Communication Interface Unit Based on GPRS Network
摘要
Abstract
In the new train control system,the wireless communication interface unit,as the transmission medium between the on-board equipment ATP and the wayside equipment RBC host,is crucial for train-trackside secure communication.In order to achieve the adaption of the train-trackside communication of the GPRS network,this paper proposes a wireless communication interface method and system for packet data services to achieve the bidirectional message transmission between the on-board equipment ATP and the wayside equipment RBC host.The hardware and software structure of the wireless communication interface unit is introduced,the data communication principle and mechanism of the wireless communication interface unit are described,the communication timing of each layer in the whole system is analyzed,and the data processing method of the wireless communication interface unit is elaborated.Compared with the interface unit in the CTCS-3 train control system,the proposed interface system significantly improves the efficiency of train-wayside communication while effectively reducing costs.关键词
