基于RFID和LABVIEW的分布式温湿度监控系统的设计

Design of distributed temperature and humidity monitoring system based on RFID and LABVIEW

研究一种基于RFID和LABVIEW的分布式温湿度监控系统,采用单片机AT89C2051作为控制核心,用SHT10作为温湿度采集传感器,再通过无线芯片n RF24L01发送数据,同时单片机接收发送来的数据并进行处理,接收端接收数据并通过串口与计算机相连,在计算机上显示数据并进行处理分析。实验结果表明,温度为26.76?C,与LabVIEW中显示的结果相一致,可以准确地显示环境温度,相对湿度为59.33%RH,与LabVIEW显示的湿度58.52%RH稍有偏差,在误差允许范围内,能满足对实时性的需求,实现监控温湿度变化的预期目标。

The text researches one kind of distributed temperature and humidity monitoring system based on radio frequency technology and LABVIEW,which uses a single chip microcomputer AT89C2051 as the control core,a chip SHT10 as a sensor for collecting temperature and humidity, then, transmitting data over the wireless chip n RF24L01, at the same time, the SCM receives the data and processes, receiving end receives the data and connects to a computer through the serial port, displaying data on the computer and beginning analysis. Experimental results show that temperature is 26.76？C,consistented with the results shown in LabVIEW, which can accurately display the ambient temperature. The humidity is 59.33% RH, with the58.52% RH shown in LabVIEW of slight deviation. In the range of allowable error, it can meet the needs of real-time,successfully achieve the desired objective of monitoring temperature and humidity.
