资料介绍

RS422总线由于其抗干扰能力强,传输距离远、传输速率高的优点,在工程中广泛应用,但是目前的RS422总线多为点对点传输或者采用标准菊花链拓扑结构,对于可靠性要求高、进行系统级备份的电路实现方式涉及较少。本文主要提供了一种基于RS422总线的交叉备份与分布式接收的应用电路,从拓扑结构、参数选择和信号质量方面展开介绍,依托实际工程应用,提供了切实可行、具有参考意义的工程应用电路。

RS422 bus has found wide application because of its strong anti-interference ability, long transmission distance and high transmission rate. However, most of the current RS422 buses have point-to-point or standard daisy-chain topology. The circuit implementation method that requires high reliability and system-level backup is rarely introduced. This paper introduces an application circuit featuring cross backup and distributed receiving based on RS422 bus. The topology, parameter selection and signal quality of the proposed circuit are described in detail. The proposed circuit is an applicable engineering application circuit based on practical engineering applications.
