基于STC89C52的灭火机器小车设计与实现

ip microcomputer as the core, and uses self-developed flame sensor device. The L293 infrared photoelectric detector is used to detect obstacles and rotate the motor forward and backward to achieve the plane motion of the fire robot. This paper introduces the self-developed 5-channel flame sensor, compares it with other types of flame sensors, and demonstrates its high measurement accuracy, relatively simple structure, stable operation, and relative safety. The E18-D50NK infrared sensor has a long detection distance, low visibility, low cost, and ease of operation. This system uses the single-chip microcomputer as the core, and the digital integrated circuit to input the sensor data into the MCU for processing of various commands. Experimental results prove that this solution is cost-effective, highly reliable, quick to extinguish fires, easy to install and debug, and has broad application prospects.
