"基于单片机的智能扫地机设计与制作"

Intelligent Sweepers based on microcontrollers are becoming more and more common in the smart technology era. These devices bring great convenience to people's lives, especially in the household setting, by providing a clean and comfortable environment. In this paper, a simple intelligent sweeper is designed using the stc89c52 microcontroller as the core control component. The advantages of this microcontroller include easy program writing, low cost, multiple functions, and high efficiency, making it widely used in the market. The intelligent sweeper is equipped with features such as obstacle avoidance and automatic dust absorption using a fan. The system consists of the microcontroller control circuit, the minimum system circuit, the infrared photoelectric obstacle avoidance circuit, the start/stop circuit, and the motor drive circuit. The design process involves schematic and PCB design using Altium Designer software, and programming the microcontroller using KEIL software to control the logic of the sweeper. In conclusion, the intelligent sweeper based on MCU offers a practical and efficient cleaning solution for households. It embodies the advancements in smart technology and contributes to the development of a more intelligent society. Keywords: intelligent sweeper; obstacle avoidance; stc89c52 microcontroller; L298N.
