摘要
提出了一种无线操控机耕船的设计方法。采用挪威Nordic VLSI公司最新推出的单片无线收发芯片nRF905进行设计,主要是通过发送端发送指令控制接收端机耕船的直流电机,从而控制离合器以及转向系统。此系统主要由接收终端和发送终端组成,各部分主要由ARM7-LPC2132单片机主芯片、液晶显示系统、RS232串口等各功能模块组成。重点说明了无线通信系统的硬件设计和软件设计,对nRF905的内部寄存器配置和收发流程进行了重点介绍,并且给出了实验测试分析。实验表明,该无线传输系统抗干扰性良好,能够很好地传输各种指令,从而较精确地控制机耕船的转动方向。
Proposed a wireless control design method of cultivating boat.Use the norway nordic VLSI's latest single-chip wireless transceiver chip of nRF905,mainly through the transmitter to send commands to control the receiver's DC motor thereby to control the clutch and steering system.The system composed mainly by the various parts of the main chip,including ARM7-LPC2132 microcontroller,LCD display system,RS232 serial port and other functional modules.Highlight the wireless communication hardware designing,software designing,the internal register configuration of nRF905 and delivery process.The results indicate that it is a good anti-interference wireless transmission system thereby transmit all kinds of good instruction.
