摘　　要：分析了CAN测温节点中实现CAN通信功能的一种方法,电路主要南独立CAN控制器SJA1000和PIC单片机组成,由于二者不能直接接口,解决办法是采用时序模拟和电路整形,经调试能够满足CAN通信要求,同时介绍了CAN接口电路设计、单片机控制电路设计和软件模拟时序等关键环节。This article analyzed one method in the CAN temperature measurement node to realize the CAN communications function. The electric circuit is mainly composed of independent CAN controller SJA1000 and PIC single chip microcomputer, but they could not connected directly, the solution to uses the timing simulation and the electric circuit reshaping, can satisfy the CAN correspondence request after the debugging. This article that was divided the CAN interface circuit design and monolithic integrated circuit control circuit design and soft timing simulation several parts introduced this method in detail.
