摘    要:RS232通讯距离短,而且只能进行点到点通讯,不能直接组建多点通讯网络。为了延长RS232的通讯距离,并将RS232节点组成通讯网络,目前广泛使用RS232/RS485信号转换器。但是,由于RS485通讯本身的局限性,在实际应用中存在许多不足。为此,可以将RS232通讯网络转换成CAN通讯网络,以更好地解决用户建立远程通讯网络的问题。

Abstract:As the RS232 interface only supports short-range and peer to peer communication, it can not directly establish a communication network. To extend the communication scope for RS232 interface and build a communication network consisting of RS232 node, the signal converter of RS232/RS485 is being widely used. Because of the limitation of RS485 itself, there are many defects in the application. This paper introduces a way to convert RS232 communication network into CAN communication network in order to support the establishment of a long-range communication network.
Keywords:CAN bus  SJA1000  82C250  RS232
