RS485-CAN总线转换器设计与实现

The design and implement of the bus converter between RS485-CAN

CAN总线因其突出的可靠性、实时性、灵活性等优点而被广泛应用,目前采用RS 485的系统还比较多,RS485-CAN转换器实现两种总线的转换。基于MCS51单片机的RS 485/CAN智能转换器,硬件电路简单,软件流程简洁,该转换器可实现RS 485和CAN的双向通信,可用于RS 485系统到CAN系统的升级。

Owing to the advantage of outstanding reliability,real-time and flexibility,CAN bus is widely used,RS 485 system are used extensively on the same time,the converter between RS485 and CAN can converter from one to another.The converter between RS485 and CAN based on MCS51 has simple hardware and compact software.It can realize the duplex communication between RS 485 and CAN,and,be applied to the upgrade from RS 485 system to CAN system.
