摘要
CRH5型动车组旅客信息系统经过多年运用,其性能和功能难以满足日益发展的应用需求。提出了一种新型旅客信息系统控制单元(PMU)的设计思路和实现方案,介绍了其系统原理和功能划分,对其硬件和软件设计的关键技术进行了分析,并对其功能上的优化提升进行了说明。该新型PMU已在CRH5型动车组进行试装,效果反馈良好。
Passenger information system of CRH5EMU has been used for many years.Its performance andfunctionality is difficult to meet the growing application demand.This article presented a design concept andimplementation scheme for a new type of passenger information system management unit(PMU),introduced thesystem principle and function division,analyzed key technologies involved in the hardware and software,anddescribed the optimization and promotion in functions of the PMU.The new PMU has been installed in the CRH5EMU,obtained good feedback.
