Abstract
This paper introduces a simple intelligent control system of automatic walking vehicle, which takes various sensors as sensitive elements and STC89C51 single chip microcomputer as the control core.This paper introduces how to use STC89C51 single chip computer to realize the graduation design of intelligent and simple automatic walking car. The design is a kind of design subject which is determined by combining scientific research projects.For the purpose of the design problem, the system adopts STC89C51 single chip microcomputer as the control core, uses ultrasonic sensor to detect the obstacle on the road, controls the automatic obstacle avoidance of the electric car, moves fast and slowly, and stops automatically.And automatically record the time, Range and speed.The circuit structure of the whole system is simple and reliable.The experimental results meet the requirements. This paper mainly introduces the hardware design method of the system.The hardware design and software flow chart of the system are described, and the measured results are given.The control technology can be used in the design of intelligent robot and automatic parking control system.
Key words: single chip microcomputer sensor PWM speed control auto walking car
