当下的电动小车基本上采用的是基于硬件电路的一种控制方法，有直线行使，或

The current electric trolley basically uses a control method based on hardware circuits, which can be driven in a straight line, or can be turned, retreated, forward, and parked under artificial remote control. But this does not meet the requirements for use in some special occasions. Therefore, this paper designs the control system of the SCM smart car. The single-chip smart car is a high-tech assembly that uses electronics, machinery, infrared sensors, and automation technologies to achieve road detection and automatic driving as a whole. It has been applied and developed in various aspects such as military and civilian use. <br>After selecting various topics, I found that the single-chip smart car is particularly interesting. It not only evokes our innovative ideas for toy cars, but also stimulates our interest in making single-chip smart cars. What is the function of the car that I usually encounter, and I want to create a single-chip smart car of my own through my own efforts. It also carries a childhood idea of ​​the intelligentization of toy cars. Therefore, I chose to make a single-chip smart car. <br>Through this design, I have mastered the working principle of the 52 single-chip microcomputer, and also understood the simple sensor composition principle, as well as the sensor testing and adjustment methods, and improved the ability of troubleshooting and hands-on ability. At the same time, through this design, assembly and debugging, I improve my hands-on ability and strengthen the theoretical knowledge I have learned, so as to establish the ability to combine the theory and practice of the single-chip microcomputer, and to recognize the relationship between the unit circuits of the sensor and the mutual influence. Thus, the circuit of each unit can be designed correctly. Master the test method and adjustment method of the sensor at the elementary level. Improve your hands-on ability and the ability to troubleshoot most of the faults. <br>This design uses a DC geared motor, the motor part uses the drive chip L298N to drive the trolley motor, the distance measurement part uses an ultrasonic module, the main control chip is STC89C52, and the automatic obstacle avoidance function part uses an infrared transceiver module.

At present, the electric car basically adopts a control method based on the hardware circuit, has the straight line exercise, or makes the turn, back, forward, parking and other functions under the artificial remote control. However, this does not meet the requirements for use in some special situations. Therefore, this paper designs the control system of the microcontroller intelligent car. Microcontroller intelligent car is a high-tech collection using electronic, mechanical, infrared sensor and automation technology to realize road detection and automatic driving as a whole, it has been applied and developed in military, civil and other aspects.<br>After a variety of topics, I found the microcontroller smart car particularly interesting, it not only arouses our innovative ideas about the toy car, but also stimulates our interest in the production of the microcontroller smart car. Usually encountered the function of the car is how, want to create through their own efforts to create a microcontroller intelligent car of their own. It also carries with it a childhood idea of the intelligence of toy cars. So I chose to make a microcontroller smart car.<br>Through this design, master the 52 microcontroller works, but also understand the simple sensor composition principle, as well as master the sensor testing and adjustment methods, improve the ability to troubleshoot and hands-on ability. At the same time, through this design, assembly and commissioning, improve self-hands-on ability, strengthen the theoretical knowledge that has been learned, so as to establish the ability of the combination of microcontroller theory and practice, cognitive sensor between the circuits of each unit and mutual influence, so that the circuit of each unit can be correctly designed. Begin to master the sensor test method and adjustment method. Improve your hands-on skills and ability to troubleshoot most of them.<br>This design uses a DC gearbox motor, the motor part uses the drive chip L298N for the car motor drive control, the ranging part adopts the ultrasonic module, the main control chip is STC89C52, the automatic barrier avoidance function part adopts the infrared transceiver module.

The current electric car basically adopts a control method based on hardware circuit, which has the functions of straight-line exercise, or turning, backward, forward, parking and so on under the artificial remote control.

What's the function of the car that I usually met? I want to create my own single-chip intelligent car through my own efforts. There is also an idea of intelligent toy car in childhood. So I chose to make the intelligent car of single chip microcomputer.<br>Through this design, we can master the working principle of 52 single-chip microcomputer, understand the simple sensor composition principle, and master the sensor test and adjustment method, so as to improve the ability of troubleshooting and hands-on ability.
