摘　　要：在工业控制领域和现代生产中,常常需要采集大量数据,并实时传给上位机进行监控。为了克服传统有线传输带来的诸多不利因素,本文设计了一种以无线射频传输芯片nRF2401和单片机AT89S52为核心的数据采集系统,现场从机采集的数据通过无线信道传送到主机,主机通过RS232与上位机PC进行串行通信,并采用VB6.0作为软件开发工具设计了实时监控平台,从而实现了对现场环境的无线智能调控。实验结果表明:该系统可实现40米内的可靠、稳定的无线通信。In the industrial control area and today＇s production,it is necessary to collect large quantity of datum and send them to PC to control timely.In order to overcome the disadvantages of wired data transmission,a new wireless data acquisition system based on nRF2401 and AT89S52 is presented.Data collected by slave is transmitted to the master,which serial communicate with PC using RS232,and using VB6.0 to design the monitoring platform,which can intelligently adjust and control locate environment.The experiment indicates that the system can realize stable and reliable wireless communication between 40m.
