摘要
随着社会的发展，人们生活水平得到很大提高。但是在人们的生活发生火灾、爆炸或者一些危险的情况时，人们近距离面对这些问题，给人们的生命及其财产带来很大的威胁。为了可以远程非接触解决这些问题，此次设计一款可以自动循迹避障小车，该避障小车通过选择单片机STC89C52单片机作为此次设计的主控芯片，通过采用MX1508作为此次设计的直流电动机，通过单片机来产生不同的PWM波形，去控制小车运行的速度，然后通过红外对管检测小车在路面行驶的轨迹及其障碍物进行检测，并将检测的数据传输到单片机进行处理，通过单片机处理输出的信号控制小车的转向及其转速，从而使得小车可以自动避开障碍物从而达到正常行驶的目的，通过红外循迹模块对当前小车车轮左右距离黑线的距离进行实时监测，并控制小车的车轮在在黑线的范围之内，用户可以根据自己的需求选择不同的路径，解决不同路径不同循迹方式及其避障的功能，所以该设计是具有研究价值和现实意义的。

Abstract
With the development of society, people’s life has been improved more and more. However, people often encounter many problems in their lives. When a fire, explosion or some dangerous situations occur, people go to the distance to solve these problems, which brings a great threat to people’s lives and their properties. In order to solve these problems remotely and non-contact, a car that can automatically track and avoid obstacles is designed this time. The obstacle avoidance car selects STC89C52 microcontroller as the main control chip of this design, and uses L298N as the DC motor for this design. The user communicates with the Bluetooth and the microcontroller through the mobile phone. The user generates different PWM waveforms through the microcontroller through different instructions under the mobile phone to control the speed of the car, and then uses the infrared tube to detect the track and obstacles on the road. At the same time, the detected signal is transmitted to the single-chip microcomputer for processing, and the detected signal is judged and analyzed by the single-chip microcomputer to control the speed and steering of the car, so that the car can avoid obstacles and drive normally, and realize the purpose of automatic tracking. Therefore, the design has research value and practical significance.
Key words: car; automatic tracking; automatic obstacle avoidance; bluetooth module
