秸秆粉碎控制系统对秸秆粉碎效率起着重要作用。秸秆粉碎系统由单片机控制,自动检测刀速,控制送料机构以不同速度执行不同动作,秸秆切碎控制系统可以有效保护电机免于长时间负载运行,防止刀具过度磨损。本文介绍了一种基于单片机的秸秆粉碎控制系统的总体设计、硬件原理设计、软件开发和仿真调试。该秸秆切碎设备控制系统主要由声音报警模块、按钮模块和进料电机驱动组成,包含光通讯输入电路模块、指示灯显示模块和速度信号采集模块,可以协调不同的模块自动检测粉碎工具的速度,控制进给电机进行前进和停止运动。

In the straw crushing process,the straw crushing control system plays an important role in the efficiency of straw crushing.Nowadays,the trend of machine automation and intelligent technology is obvious.The straw crushing system is controlled by a microcontroller,which automatically detects the knife speed and controls the feeding mechanism to execute different actions at different speeds.Based on this advantageous feature,the straw crushing control system can effectively protect the motor from long time load operation and prevent excessive tool wear.This paper presents the general design,hardware principle design,software development and simulation debugging of a microcontroller-based straw crushing control system.This straw crushing equipment control system mainly consists of an audible alarm module,a button module and a feed motor drive.In addition,the system also contains optical communication input circuit module,indicator display module and speed signal acquisition module,and the core of its control system is STC89C51 microcontroller.In this paper,peripheral circuits such as Hall-type speed sensors and signal conditioning circuits are developed.The whole control system automatically detects the speed of the crushing tool by coordinating different modules to control the feed motor for forward and stop motion.
