智能循迹小车运动过程中会遇到各种障碍物，会造成交通安全或发生意外事故的危险，假如能设计一款智能系统对小车的安全距离进行实时监测，提早发现障碍物并及时调整小车行驶方向，能够有效避免交通意外的发生，为此，本文基于STC89C52单片机，设计一款智能蓝牙循迹小车，通过无线通信方式实现手机控制智能小车进行前进、后退、左移、右移，从而进行自动躲避障碍物，实现小车的避障和循迹功能，当检测到前方有障碍物时，可以小车后移、左移或者右移，利用光电传感器实现智能小车行进中的实时测距，采用蓝牙4.0技术来完成无线通信的总体方案，然后从整体对软硬件进行了设计，包括功能、选材、布线等。经过实物测试小车可以自动避开障碍物从而达到正常行驶的目的，所以该设计是具有研究价值和现实意义的。

Abstract
Intelligent tracking car will encounter various obstacles in the process of movement, which will cause traffic safety or the risk of accidents. If an intelligent system can be designed for real-time monitoring of the safety distance of the car, early detection of obstacles and timely adjustment of the direction of the car, traffic accidents can be effectively avoided. Therefore, this paper based on STC89C52 microcontroller, Design a smart Bluetooth tracking car, through wireless communication to achieve mobile phone control smart car forward, backward, left and right, so as to automatically avoid obstacles, to achieve the car obstacle avoidance and tracking function, when there is an obstacle in front of the detection, the car can move back, left or right, the use of photoelectric sensors to achieve the smart car moving real-time ranging, Bluetooth 4.0 technology is used to complete the overall scheme of wireless communication, and then the software and hardware are designed from the whole, including function, material selection, wiring and so on. After the real test, the car can automatically avoid obstacles to achieve the purpose of normal driving, so the design is of research value and practical significance.
Key words: car; automatic tracking; automatic obstacle avoidance; bluetooth module
