Design of Experimental Training Device Based on CAN Bus for Automotive Microcontroller and LAN

设计了一种汽车单片机与局域网技术实验实训的教学设备.系统用STC89C51单片机为电控单元的处理器,通过传感器对发动机的冷却液温度进行采集,经电控单元处理后送执行器实时显示;用SJA1000作为CAN控制器,通过CAN总线传输到其它电控单元实时显示温度.系统已应用于汽车单片机与局域网技术课程教学.

This paper introduces the design of an experimental training device used for automo- tive microcontroller and LAN teaching. With STC89C51 processor of the electronic control u- nit, the device collects the coolant temperature through sensor and provides real-time display after the processing of electronic control unit. The device has SJA1000 as its CAN controller and transmits the real-time temperature to other electronic control units through CAN bus. The device has been applied to the teaching of Automotive microcontroller and LAN technology course.
