研究了列车乘客信息系统多硬件平台、多软件层次背景下的远程配置维护问题,并设计相应的维护软件。该软件能够对系统中设备程序进行良好的维护,方便维护人员及时更新程序,使广播视频功能正常运行。分析了该维护软件的主要功能及其实现方法。该软件目前已在某地铁项目中应用。

The train passenger information system includes three system modules ,the train broadcasting system ,the video system for the passengers and the closed-circuited television monitoring system. Various applications and the underlying support program that accomplishes functions of the system run in the who~ train system. To ensure the stability of the system,it is necessary for the maintenance personnel to conduct a comprehensive control of the information,the system maintenance will be convenient. The maintenance plays an important role in the normal implementation of the system function. This paper studies remote configuration and maintenance of the train passenger information system under the background of many hardware platform and many software levels,and designs the corresponding maintenance tool. The software can finish the maintenance job for the program of the equipment well. It is convenient for maintenance personnel to update the program timely. Thus,the radio and video function can make a perfect achievement. This paper analyzes the main functions of the software and the method of its implementation. This software is already used in one subway project.
