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。

Abstract: 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.
