Abstract

This paper designs an automatic obstacle avoidance tracing vehicle control system based on single chip computer. Based on STC89C52 single chip computer as control core, this paper detects the preset tracing guide line with infrared photoelectric sensor and feeds back the detection signal to single chip computer. The single chip computer will analyze and judge the acquired information and control L293D chip will drive DC motor for the control of left and right wheel rotation speed and adjustment of vehicle rotation direction so that the vehicle can automatically drive along the preset tracing and achieve the automatic tracing function. The operator uses HC-SR04 ultrasonic sensor to achieve obstacle avoidance and distance measurement function. The display module and alarm module equipped is able to have real time acquisition, display and control of the vehicle operation status and parameters. It designs and debugs the hardware circuit and designs the control software program. The vehicle is able to realize automatic tracing, obstacle avoidance and distance measurement function through physical test. It can run stably and reliably. The system circuit of simple structure and easy operation is applicable to unmanned factory, logistics, scientific exploration and other fields, which is of strong practicability and promotion value.
