基于STC89C52的灭火机器小车设计与实现

Abstract In this project, a fire-fighting robot based on the STC89C52 microcontroller is developed. It utilizes a self-developed flame sensor device and an L293 motor driver with infrared photoelectric detectors to detect obstacles and control the movement of the robot. The paper introduces a self-made 5-channel flame sensor, comparing it with other types of flame sensors. This sensor has high measurement accuracy, a relatively simple structure, stable operation, and is relatively safe. The E18-D50NK infrared sensor has a long detection distance and low visibility, making it easy to configure, affordable, and easy to operate. The system uses the microcontroller as the core to process the sensor data and execute various commands. Experimental results show that this solution is cost-effective, reliable, quickly extinguishes fires, and is easy to install and debug, with broad application prospects.
