摘　　要：车载设备在开发和调试过程中需要对设备的运行状态进行检测。在车运行状态下实现设备内部变量的检测和调试信号的产生往往比较麻烦。文中提出的车载多通道调试系统是一种基于CPCI总线的嵌入式调试系统,它可以根据系统需求将设备内部变量的状态转换成模拟量信号实时输出,方便对设备工况的检测。同时,车载多通道调试系统可以输出设定波形和频率的调试波形,方便对系统的调试。The status of onboard device needs to be detected during development and debug process. However, it＇s hard to detect onboard device＇s internal variables during train running. This paper represents an embedded debug system based on PCI bus. It can transfer the onboard device＇s internal variables into real-time analog signals, which facilitates the detection of onboard device＇s status. It can also output specified waveform that is beneficial to debug process.
