An intelligent fire extinguishing trolley is designed to address the problem of high firefighter casualties under fire.This intelligent cart is based on GD32 microcontroller,equipped with smoke sensor,water tank and water pump.Through the infrared tube to realize the trajectory function,ultrasonic sensors to realize the obstacle avoidance function.On the basis of trajectory and obstacle avoidance,it realizes the smoke sensor and fire extinguishing function.When the MQ-2 smoke sensor senses smoke,it outputs a high level to the microcontroller,which in turn controls the water pump to spray water to extinguish the fire.The trolley is stable and responsive,and has high practical value.
