毕业设计-智能循迹小车

摘要

本次设计的智能循迹小车是以单片机 STC89S52 为主控制器，运用反射式红外传感器来进行路径检测和霍尔传感器监测行驶路程，并将实时数据传送到LCD12232显示模块，同时传感器组成的循迹模块路径检测状态传回单片机进行处理，用单片机产生 PWM 波等方式来控制小车的行进速度，实时控制小车的行进状态。
 另外， 在小车上还扩展了 LCD12232 作为人机交互界面，以便于实时了解监测传感器的状态和小车行驶中的实时数据，由于本次设计的是智能自动循迹小车，整个任务过程无需人工的任何干预，故而没有进行键盘及遥控等的人工操作设备。用多路传感器的实时监测和算法的紧密配合来保证小车的顺畅完成任务。

关键字：智能循迹小车，红外传感器，霍尔传感器，12232液晶。
Abstract
  This design's intelligence follows the mark car is by the monolithic integrated circuit STC89S52 primarily controller, carries on the way examination and the Hall sensor monitor travel distance using the reflection type infrared sensor, and transmits the real-time data to the LCD12232 display module, simultaneously the sensor composes follows the mark module way examination condition to feed in the monolithic integrated circuit to carry on processing, has ways and so on PWM wave with the monolithic integrated circuit to control car's approaching speed, the real-time control car marches forward the condition.
 other, also expanded LCD12232 on the car to take the man-machine interaction contact surface, was advantageous for the real-time understanding to monitor in sensor's condition and the car travel real-time data, what because this design was the intelligence follows the mark car automatically, the entire duty process did not need the artificial any intervention, therefore has With the multi-channel sensor's real-time monitors and the algorithm close coordination guaranteed that the car completes the task smoothly.
 
 
 key words: The intelligence follows the mark car, infrared sensor, Hall sensor, 12232 liquid crystals.
