基于MCS-51单片机智能小车 控制器设计与实现
Abstract
This article briefly introduced the development background and significance of the system, and introduced the process of the hardware design and the software design with emphasis This selected topic with the single-chip microcomputer technology to develop intelligence car which can realizes the automatic advance, makes a turn, the backlash the basic function and so on through examining the road surface. So it may conveniently apply in the road surface security inspects. The car hardware control unit mainly included three parts: the sensor and its recuperate electric circuit, stepper motors and the actuation electric circuit, the controller, and manufactured the schematic diagram and the electric circuit board with protel99. In the software design aspect, then which divided into three modules: data acquisition module, signal processing module, The controller control electrical machinery module. This design structure is simple, therefore, it controls the signal sampling frequency and the electrical machinery rotational speed with the traditional assembly language programming, using the timer severance. Finally, it basically realized the prearrange function in this design topic through the software and hardware debugging and a try run.
