基于虚拟仪器的温室环境无线监控系统研究

Research on Greenhouse Environment Wireless Monitoring System Based on Virtual Instrument

采用分布式的系统结构方式,构建了以STC89C52单片机为核心的数据自动采集系统,利用温度、湿度、光照度等传感器组成的测量电路,实现了对温室环境参数的自动采集;温室里从机采集的环境数据通过无线模块nRF905发送到主机控制室,最后传送到计算机,完成数据的采集。计算机利用LabVIEW软件实现对数据的获取、处理和显示等功能,实现对温室环境的无线监控。

Using distributed system structure,STC89C52 automatic data acquisition system was constructed.This system with sensors of temperature,humility and light intensity.etc achieved the automatic collection of greenhouse parameters.The environment data collected by subordinate SCM were sent to superior SCM,from which computer get the data finally.LabVIEW software was used in computer to acquire,process and display greenhouse parameters and realize wireless monitoring of greenhouse environment.
