动车组检修信息通讯终端系统的设计与实现

摘要

With the development of China Railway High-speed , the repair workload of Electric Multiple Units is increasing greatly . The effective information communication during the EMU repair period can contribute a lot to the repair efficiency . Based on the Electric Multiple Units Management Information System ( EMU-MIS ) , this paper designed and developed an embedded repair information publishing system to realize the real time data communication among repair stuffs . The system was based on the ARM processor and the embedded Linux , adopted the transplanted BlueZ as middle ware , and implemented the functions of repair plan issue , EMU faults transmit , and repair process publishing. The practice proved that the system could play an constructive role for the repair of EMU and has prospect for extension to other depots .%本文依托既有的动车组管理信息系统，设计实现一种嵌入式检修信息通讯终端系统，实时与检修员手机进行各类检修数据交换。该系统基于 ARM 处理器的硬件平台和嵌入式 Linux 操作系统，移植了蓝牙协议栈，实现了检修计划通讯、实时故障传达，、检修进度通告等功能。试点实践表明，该终端系统能够实时传达各类检修信息给检修员，提高了检修效率，且成本低，实施方便，具有在全路动车所推广的前景。
