Intelligent trolley based on single-chip microcomputer control

The invention discloses an intelligent trolley based on single-chip microcomputer control. According to the intelligent trolley, the STC89C52 single-chip microcomputer serves as a control core, a fire source can be automatically detected, the position of the fire source can be automatically positioned, obstacles can be automatically avoided in the situation process, and the trolley is intelligently guided. A light-sensitive transistor sensor is used for detecting a fire source signal, when the fire source is detected, the posture and form are automatically adjusted to be near the fire source and aligned with the fire source, then a fire extinguishing motor is started to drive fire extinguishing equipment to extinguish fire, an infrared photoelectric switch inductively controls a trolley to run in an obstacle avoidance mode, and the trolley is driven by an L298N driving circuit. And the vehicle-mounted display screen displays the current running state and the fire extinguishing state of the trolley to a user.
