车载移动视频通信控制系统的研究与实现

Research and Implementation of Mobile video communication control system in Train

为满足轨道交通通信系统对可靠性、占用空间、可维护性的需求,本文提出利用linux系统在U盘上构建便携式移动系统作为车载移动视频通信控制系统。该系统采用了镜像文件系统,所有的文件目录都为只读的,系统文件不易被破坏。同时去掉了许多不必要的应用,保证了系统大小。本文设计并构建了一个可以在U盘上运行的linux作为车载移动视频通信控制系统,并在实际环境下进行了测试,该系统目前已经在武汉二号线、重庆三号线中使用。

In order to meet the requirements of communication system of rail transportation on the reliability,memory cost,maintainability,this paper prosposes a method to build the mobile video communication control system in train by using Linux system on flash disk.The system uses the image file system,all of the files are read-only,so the file system is not easy to be destroyed.The system remove the many unnecessary files,to ensure the system size.The paper design and construct the mobile video communication control system in train by using Linux system on flash disk,and is tested on actual environment.This system has worked in Wuhan rail transit line 2 and Chongqing rail transit line 3.
