Intelligent Sweeper Based On MCU-Circuit system design,assembly and debuggingAbstractNowadays,machines are becoming more and more intelligent.With the coming ofintelligent era,intelligent machines also bring many conveniences to people.Home intelligentmachine is the most widely used place,and intelligent sweeping can bring great convenienceto people.It can not only bring comfortable and clean environment to human,but alsopromote the development of social intelligence.This paper mainly designs a simple intelligent sweeper.The core control component ofthe sweeper is STC89C52,which has the advantages of simple programming,low cost,morefunctions and high efficiency,so it is widely used in the market.In addition,the sweeper canautomatically avoid obstacles and use the fan for dust collection.This paper introduces thewhole manufacturing process of the sweeper system,which is mainly composed of the maincontrol circuit,the minimum system circuit,the infrared photoelectric obstacle avoidancecircuit,the key start stop circuit and the motor drive circuit.By using the integrated circuitdesign software of Altium designer,the schematic diagram and circuit board are designed.Secondly,the logic of the whole sweeper is controlled by the program of keil.Keywords:intelligent vacuum cleaner;barrier;stc89c52 single chip microcomputer;L298N
