摘要
本文设计了一种基于RS485串行总线的集散式测控系统。本系统主要由以下几个控制器部分组成:上位机、数据采集模块、继电器阵列模块。RS-485作为一种硬件设计简单、控制方便、成本低廉的通信方式,实现了这些模块的统一协调通信,实现一主(PC机)多从(多个PIC16F877子系统)的集散式测控系统。
A new distributed control system based on RS485 serial data bus is designed in this paper. It is consist of several parts as following: Computer, data sampling module, and recharge machine array module. As a simple designing, convenient controlling, and low cost communication method, RS485 implements the communication between these modules. Finally, the distributed control system with one PC and several PIC16F877 systems is implemented.
