The invention relates to a train passenger information system based on an Ethernet and an MVB bus and a control method thereof, the train passenger information system comprises a main control card ACSU, DACUs installed in each cab, a PECU installed in a passenger room, PACUs installed in each compartment and a monitoring module, the main control card ACSU, the PECU and the PACUs are in communication connection through the Ethernet or the MVB network, and the monitoring module is connected with the DACUs. The Ethernet and the MVB network are mutually redundant, and the monitoring module is in communication connection with each terminal device and is used for collecting the online state of each terminal device and switching a backbone network and a standby network through abnormity judgment. A dual-network architecture mode is adopted in the passenger information system, data can be transmitted through the Ethernet/MVB at the same time, data transmission of the train information system is not affected by faults of one bus, the two networks can be seamlessly connected, the advantages of the Ethernet and the MVB network can be exerted at the same time, the high redundancy effect is achieved, and the reliability of the train information system is improved. The method can be widely applied to the field of rail transit and has a good market prospect.

    本发明涉及一种基于以太网和MVB总线的列车乘客信息系统及其控制方法,包括:主控制卡ACSU、安装在每个驾驶室中的DACU、安装在客室的紧急对讲通话器PECU、安装在每节车厢中的PACU以及监控模块,主控制卡ACSU、PECU、PACU之间通过以太网或MVB网络进行通信连接,以太网和MVB网络相互冗余,监控模块与各终端设备通讯连接,用于采集各终端设备的在线状态,并通过异常判断切换主干网络和备用网络。本发明在乘客信息系统中采用双网络的架构方式,数据可以通过以太网/MVB同时传输,一条总线故障不影响列车信息系统的数据传输,两个网络可以无缝衔接,同时可以发挥以太网、MVB网络自身优势,达到高度冗余的效果,能够在轨道交通领域获得广泛应用,具有良好的市场前景。
