摘要
本文给出一种全新的、基于 CAN 总线驱动器 PCA82C250的分布式工业测控系统的网络组成。该系统克服了 RS-485的许多缺点,既具有 CAN 总线传输距离远、传输速率快、可靠性高等的特点,又具有等同于 RS-232的编程容易、接口简单的优势,可以使工程师完全摆脱对 CAN 控制器82C200(或者 SJ1000)的接口和编程。实际应用表明,这是一种可以替代 RS-485,组成简易、实用的 CAN BUS 系统。
This paper presents a new distributed industry measure system based on CAN BUS driver PCA82C250. The system overcomes much disadvantage of RS-485. It has such advantage as far transmission distance, high transmission baud rate, high reliability etc. At the same time, it has the advantage of RS-232 simple interface and easy programming. So, the engineer can get rid of the interface and programming to CAN controller 82C200（or SJ1000） . The practice indicates that it can make up of facile CAN BUS system instead of RS-485.
