ABSTRACT

With the rapid development of urbanization, the incidence of fire accidents has also soared, posing a significant threat to people's lives and property safety. In this context, the intelligent fire-extinguishing car was born. STC89C52 microcomputer unit (MCU) is the control core. The system circuit comprises the minimum system of MCU (including crystal oscillator circuit and reset circuit), sensor module, tracking module, infrared obstacle avoidance module, ultrasonic obstacle avoidance module, steering gear module, fire extinguishing fan module, and infrared remote-control module. The system has two control modes: manual and automatic. In manual mode, the car can be controlled by MP3 infrared remote control to move forward, backward, left, and right, and the steering gear can be rotated so that the car can go to the destination to carry out manual fire extinguishing. In the automatic mode, the car patrols along the set route and automatically avoids obstacles, detecting the temperature of the surrounding environment. When a fire occurs, the car's fire source detection module sends a signal to the MCU, and the MCU determines the flame position and drives the steering gear to rotate the corresponding angle so that the fan faces the fire source to extinguish the fire.
