摘要
介绍CTCS-3级列车车载系统采用多功能车辆总线(MVB)进行通信的功能单元以及各个单元间的周期性和突发性通信行为。在对MVB总线协议以及上层应用协议进行分析的基础上,以MVB-Ethernet网关为例,详细介绍MVB通信网关的硬软件实现技术以及MVB网关设备在半实物仿真平台中的应用。
This article introduces the MVB functional block used in CTCS-3 onboard system and reveals the communication details in MVB bus, including both the periodic communication and the burst communication. Based on the analysis of the MVB application protocol, the article shows the details of the software/hardware implementation of an MVB-Ethernet gateway. And it also demonstrates the application of this gateway in semi-physical simulation platform.
