摘要

设计了基于射频芯片nRF2401和微处理器LPC938为核心芯片的无线收发节点

通过RS—232与电脑相连

实现多台电脑之间数据的无线传输。该节点具有无线中继功能

能够进行多达二级的无线中继

极大提高了数据传送距离和避开障碍物的能力。实验表明:如果采用二级中继

数据传送距离由无中继时的10m提高到30m。

Abstract

A wireless node based on radio chip nRF2401 and CPU of LPC938 is designed.By connecting with the computer by RS—232

wireless transmit data between the computers are realized.The node possesses wireless relay function and can reach two degree wireless relay

the distance of data transmission and the capability of keeping away from bar are improved greatly.The experiment indicates that the distance of data transmission can be increased from 10 m to 30m if using two degree wireless relay.
