摘要
本文设计并实现了一种采用单片射频收发芯片nRF905、DS1820、单片机AT89C51和PC机的无线数据采集系统。系统以温度数据处理模块、温度数据收发模块和温度数据采集模块三大模块。系统能够实现温度信息的采集、传送和LED显示,并且在温度达到最大值时,驱动蜂鸣器产生报警信号。并且温度数据能远端PC机上显示、保存、统计、可以远程监控。本系统降低布线成本、易于维护、提高了可靠性。
Design and realize a wireless acquisition system by using nRF905, DS18B20,AT89C52 and PC. The system consist three modules, data process module, data transceiver module, data acquisition. The system can collect and transmit temperature information and display it on LED, when the temperature excess the set value, the system will alarm by the buzzer. And temperature data can be displayed on the PC, preservation, and statistics, remote monitoring can be. The system low the cost of wiring, easy to maintain and improve the reliability.
