为确保高速磁悬浮列车可靠运行,设计了基于CAN的车载诊断网络系统。它对车载设备诊断信息进行采集、分析和诊断,形成各车载设备的详细诊断信息,提供给地面人员和列车驾驶员参考。介绍了CAN总线技术及其特点,车载诊断网络系统的基本结构,基于CAN总线的车载诊断网络系统的硬件结构,完成了嵌入式环境WindowsCE下包含数据库的车载诊断网络系统的基本软件设计,并通过了试验室测试。
In order to ensure the reliable operation of high-speed maglev train, a CAN based on-board diagnostic network system is designed. It collects, analyzes and diagnoses on-board equipment diagnostic information to form detailed diagnostic information for each on-board equipment and provides it to ground personnel and train drivers for reference. This paper introduces the CAN bus technology and its characteristics, the basic structure of on-board diagnostic network system, the hardware structure of onboard diagnostic network system based on CAN bus, and completes the basic software design of on-board diagnostic network system including database in embedded environment under Windows CE Laboratory test.
