摘　　要：为保证安全性与可靠性,车用设备电路板必须经过长时间老化测试。由于需要老化电路板数量较大,设计了一个基于CAN总线的老化测试系统。介绍了系统各个模块的功能与设计,详细介绍通信模块处理串口通信的实现方法及通信模块与测试模块的CAN通信机制。In order to guarantee the security and the reliability of the equipment used in the car, the circuit board in the equipment must be checked and tested for a long time in an aging and testing system. So the aging and testing system based on CAN-bus is designed. The function and the design of every module of the system is described. The implementation the communication by a serial port is described in detail. The mechanism of the communications between the communication module and the test modules by CANbus are also described in detail.
