摘要
文章介绍了一种基于超声波测距技术的室内无线精确定位智能小车控制系统的设计。该系统以msp430f149单片机为主控芯片,利用步进电机带动超声波传感器组进行定位数据采集,通过电子指南针的角度检测控制小车进行方向定位。利用n RF905无线模块实现了双机无线通信及数据交换,将采集数据绘制成坐标点显示在控制端触摸屏上,实现触摸屏上小车位置的显示,并通过点击触摸屏实现控制小车找相应位置的功能。
This paper introduces the design of intelligent car control system based on ultrasonic ranging technology for indoor wireless precise positioning.. The system with MSP430F149 microcontroller as the main control chip, using the stepper motor drives the ultrasonic sensor group positioning data collection, through the electronic compass angle detection control car orientation. By nRF905 wireless module duplex radio communication and data exchange is realized. The collected data plotted coordinates display in the control side touch screen, touch screen of trolley position display, and by clicking on the touch screen to achieve control of the car to ifnd corresponding to the position of the function.
