摘要
CAN总线是目前使用较为广泛的现场总线,技术成熟、可靠性高、功能完善、成本合理;RS485是一种平衡传输的串行通信方式,在集中控制领域大量使用,但是具有许多局限性;RS485-CAN网关实现由RS485总线网络和CAN总线网络的互联,同时实现RS485总线网络向CAN总线网络过渡。
CAN bus is used widely more and more now.It is mature technology,high reliability,comprehensive function and reasonable cost.RS485 is a balanced transmission of serial communication.It is used large-scale in the field of centralized control,but it has many limitations.RS485-CAN gateway has the function of interconnection between the RS485 network and the CAN bus network,while enables transition from the RS485 bus network to the CAN bus network.
