磁悬浮列车车载诊断系统设计

Vehicle Diagnosis System Design for the Maglev Train

以上海磁浮运营示范线的德国高速磁悬浮列车为背景,以磁悬浮列车的国产化为目的,简要介绍了磁悬浮列车车载诊断系统的软硬件构成;针对车载诊断系统的结构框架、设计方案、功能模块、数据流向等方面进行了分析,设计了基于CAN总线的通信协议、信息安全处理方法以及程序流程;以VB.NET语言作为开发平台,在W indows CE.NET嵌入式操作系统下设计了系统软件;给出了软件的部分代码和注释,阐述了软件的主要设计思想和应用模式,并给出了软件的运行界面和测试结果。

On the basis of the German high-speed maglev train of the the Shanghai demonstration line, with the intent of the localization of the maglev train, it introduces the software and hardware structure of vehicle diagnosis system briefly. The designing scheme, programming method, function modules and network communication flow of vehicle diagnosis system are analyzed, The communication protocol based on CAN bus and message security implement are also given out. It designs a software for vehicle diagnosis system with Visual Basic. NET based on Windows CE. NET embedded system. Parts of programme codes and note are given out, main flow diagram and applying mode of this software are elaborated, running in terface and conclusion of the test are alsopresented.
