摘要
设计了基于MODBUS协议的主从控制系统,采用触摸屏与单片机通过RS232串口通信。扩展了单片机系统外围电路,由数字输入、数字输出、温度测量等模块组成,编写了上下位机测试程序,实现了电机控制,温度测量等功能。该系统可广泛应用于小型工业设备控制,具有很好的可移植性和经济性。
Design a master-slave control system based on MODBUS protocol which is used for the RS232 serial communication between HMI and MCU.Expand the outer circuit for the MCU which contains digital input,digital output,temperature measurement modules.Write test program for HMI and MCU to realize the system function such as motor control and temperature measurement.This system can be widely used in the small industrial control equipments and it is good at portability and economy.
