自定位运动控制系统小车系统设计

Design of a self-positioning motion control system for cars

为了实现小车自定位运动的功能,设计出基于GPS信息处理和电子指南针数据来控制车的行动轨迹从而实现自主导航的控制方案。以AVR单片机作为控制枢纽,通过相关硬件模块以及电路的设计实现对小车良好控制。电机与舵机直接由电池经过一些限流管供电实现稳定工作。实践检验,系统能够实现自定位功能,并能够按照一定的路线到达指定的位置。

In order to realize the function of self positioning movement of cars, a control scheme is designed based on GPS information processing and electronic compass data to control the trajectories of the cars. With an AVR single chip microcomputer as control hub, the system makes the cars in good control with the design of related hardware modules and circuits. The motor and steering gear are powered by batteries directly through some current limiting tubes for system stability. Practical tests show that the system can realize the self-positioning function and arrive the specified location following a certain route
