摘　　要：新型车载控制及诊断系统部件是高速磁浮窄车体车载控制及诊断系统中的重要单元设备,其功能是将来自车载安全计算机的与安全相关的控制指令发送给车辆子系统,并将子系统发送的状态监视信号反馈给车载安全计算机;为保障控制及诊断系统的安全可靠运行,新型车载控制及诊断系统部件采用冗余架构及模块化设计,形成双重冗余的架构,使设备达到了高度稳定,并且简化了电路设计;设备通过车载试验及试验结果分析,验证了设备满足设计要求,能够在磁悬浮列车上稳定可靠运行。The new on-board control and diagnosis system component is an important unit equipment in the on-board control and diagnosis system of high-speed maglev narrow vehicle body.Its function is to send the safety related control instructions from the on-board safety computer to the vehicle subsystem,and feed back the status monitoring signal sent by the subsystem to the on-board safety computer.In order to ensure the safe and reliable operation of the control and diagnosis system,the components of the new on-board control and diagnosis system adopt redundant architecture and modular design to form a dual redundant architecture,which makes the equipment highly stable and simplifies the circuit design.Through on-board test and analysis of test results,it is verified that the equipment meets the design requirements and can operate stably and reliably on maglev train.
