摘　　要：根据对CRH3型动车组网络控制系统结构的分析,研制基于多功能车辆总线(MVB)的CRH3型动车组单车电气调试系统。该系统由硬件和软件两部分组成:硬件部分采用可移动式机箱,具有易散热、高强度和易操作的优点,且使用第4类MVB通信网卡替代中央控制单元,实现总线管理功能,并利用MVB信号判断动车组电气线路连接是否正确,对各车载设备功能做初步测试;软件部分采用模型—视图—控制器(MVC)框架设计,采用Visual C++语言设计用户界面,利用图标动态反映当前被测车体的电气连接状态。该单车电气调试系统不但接口简单,移动方便,通信接口及功能可配置,能够大大提高CRH3型动车组的电气调试效率,有效降低调试时的出错概率,还可通过变更接口和功能配置文件,使其适用于列车网络基于TCN的其他型号动车组的调试。According to the analysis of CRHa EMU network control system, the single car electrical test system of CRH3 EMU based on Multifunctional Vehicle Bus （MVB） is developed. The system consists of hardware and software. For hardware, a movable cabinet is adopted, which has such advantages as easy heat dissipation, high strength and easy operation. Class 4 MVB communication card instead of central control unit is used to realize bus administration and MVB signal is used to determine whether the connections of EMU electrical circuits are correct and perform preliminary tests for the various functions of on-board equipment. The framework of model-view-controller （MVC） is adopted to design software and Visual C＋ ＋ to design user interface. The electrical connection state of the being tested car is dynamically reflected by icons. The single car electrical test system not only has simple interface, it＇s easy to move, the communication interface and functions can be configured, which can greatly improve the efficiency of the electrical commissioning of CRH3 EMU and effectively reduce the error probability, but also can adapt to other types of EMU which based on TCN network by changing the configuration files of interface and function.
