基于LPC2131的RF遥控智能小车的设计

Design of RF Remote Controlling Intelligent Vehicle Based on LPC2131

针对传统红外线遥控系统接收器在方向性和距离方面受限的缺点,提出采用RF(radio frequency)无线通信技术对智能小车进行遥控的方法,并设计了智能小车RF遥控系统。系统以ARM7-LPC2131为控制器、nRF905无线数据收发模块为无线遥控载体、液晶屏为人机交互界面搭建了系统硬件平台,并且使用C和C++语言编写了系统软件。系统经过调试,可以实现预定功能。无线遥控距离可以达到300 m,通信效果稳定可靠。

In view of the defect,restricted direction and distance of the receiver used in traditional infrared remote control system,the remote controlling method based on the wireless radio frequency communication technology was put forward for controlling the intelligent car,and the design and production of wireless remote controlling system was accomplished.The hardware platform of system was built with ARM7-LPC2131 development board,NRF905 wireless data transceiver module for wireless remote control vector,LCD screens built hardware platform for the interactive interface,and the system software was written in C and C＋＋ programming language.The system was debugged and achieves the preconcert function.The communication distance of wireless remote control can reach to 300 meters,and the communication was stable and reliable.
