现代智能技术的发展给我们生活的各个领域都带来了极大的便利，人类社会对智

The development of modern smart technology has brought great convenience to all areas of our lives, and the research on smart car technology in human society has reached a new height. This article is based on the STC89C52 single chip microcomputer to design an intelligent tracking obstacle avoidance car, through the infrared detection technology to detect the signal and infrared transmitting tube and receiving tube to perceive the established trajectory and obstacles, and then feedback the sensed signal to the single chip microcomputer and distinguish the different signals, and finally Combined with software programming to control and realize the established track and obstacle avoidance functions of the trolley, that is, when an obstacle is detected in the front, it will automatically alarm to adjust and avoid, and automatically track after passing through the obstacle area. The experimental results show that each module can achieve the expected effect, and the system design scheme is feasible.

The development of modern intelligent technology has brought great convenience to all fields of our life, and the research on intelligent car technology has reached a new height in human society. Based on STC89C52 single-chip machine, this paper designs intelligent trail-avoidance craft, senses the established trajectory and obstacles through infrared detection technology detection signals as well as infrared transmitters and receiving tubes, then feedbacks the perceived signal to the synth machine and distinguishes between different signals, and finally combines software programming to control the implementation of the car tracking and barrier-avoidance function, that is, when the obstacles in front of the detection, automatically adjust the alarm to avoid, after the obstacle zone. The experimental results show that each module can achieve the desired results and the system design scheme is feasible.

The development of modern intelligent technology has brought great convenience to all fields of our life, and the research of intelligent car technology in human society has also reached a new height. This paper is based on STC89C52 microcontroller to design intelligent tracking obstacle avoidance car, through the infrared detection technology detection signal and infrared transmitting tube and receiving tube to perceive the given track and obstacles, and then feedback the sensing signal to the single chip microcomputer and distinguish different signals. Finally, combined with software programming to control the car to track the established track and obstacle avoidance function, that is, when detected When there is an obstacle in front of you, it will automatically alarm, adjust and avoid, and automatically follow the path after passing through the obstacle area. The experimental results show that each module can achieve the desired effect, and the system design scheme is feasible.<br>
