车载终端系统中CAN总线通信的研究设计

Study on CAN Bus Communication in Vehicle Terminal System

提出一个具有CAN网络通信的车辆远程终端系统方案,使用了Motorola公司的16位微控制器MC9S12DG128作为单片机,简单介绍了这种单片机的结构特点及其功能,给出了与CAN通信相关的软、硬件设计,从而实现了该监控系统。该系统具有结构简单、可靠性强、实用性强等特点。

This paper presents a long-range vehicle terminal system which uses Motorola＇s 16-bit microcontroller Mcgs12DG128 as single chip. It briefly introduces the structure features and function of this single chip, and gives CAN communication-related hardware and software design,in order to achieve the realization of the monitoring system. The system is simple,reliable,practical and so on.
