Abstract
The topic selection of the graduation project comes from the combination of practical application needs and technological innovation and exploration. The design of intelligent sweeping vacuum car based on STC89C52 SU aims to use infrared sensors and ultrasonic modules to realize environmental perception and autonomous obstacle avoidance, and meet the needs of home cleaning automation. Through this design, it not only improves the cleaning efficiency, but also shows the broad application prospect of SCM in the field of intelligent control.
This paper designs an intelligent sweeping car based on STC89C52. By integrating the infrared sensor and the ultrasonic module, the car realizes the real-time detection and sensing of the surrounding environment. The car can intelligently plan the operation trajectory according to the detected environmental information, and accurately control the travel speed and direction through the different PWM pulse signals output by the MCU. After physical testing, the intelligent sweeping vacuum car can walk autonomously according to the predetermined trajectory, and has the ability to automatically detect obstacles and independently avoid obstacles. This design not only improves the automation and intelligent level of sweeping and vacuuming, but also provides a useful reference for the design of similar intelligent mobile platform.
