基于无线传感器网络的农村温室大棚监控系统

针对现有农村温室大棚环境差、监测困难及有线传输系统成本太高等问题,设计了针对温室大棚中温湿度、CO2浓度、光照强度和土壤温度等参数的无线实时监控系统。系统采用WiFi技术的无线传感器网络对检测到的大棚中环境参数进行采集、分析、处理和传输,并将数据在监控中心PC机上显示。当超过预先设定的阈值时,可以通过蜂鸣器报警和GSM短信息报警。系统给出了硬件电路和软件流程图,通过无线传感器网络实现了数据高速传输,已达到对农村温室环境的有效监控。提高了温室环境参数监控系统的灵活性和移动性,降低了温室环境监测的成本。

Rural Greenhouse Monitoring System Based on Wireless Sensor Network

Aiming at the problems of the existing rural greenhouse environment is poor, monitoring is difficult and cable transmission system cost is too high, a wireless real-time monitoring system is designed for greenhouse＇s temperature and humidity, C02 concentra- tion, light intensity, soil temperature and other parameters. It uses wireless sensor network of WiFi technology to collect and analysing processing and transporting the greenhouse environment parameters, then it displays the data in the monitoring center PC, when it ex-ceeded a preset threshold value, the buzzer alarm and GSM short message alarm are realized. The system gives the hardware circuit and software flow chart, through wireless sensor network the design achieves high-speed data transmission and reaches the favorable monito-ring of rural greenhouse environment. The system improves the flexibility and mobility of the greenhouse environment parameters moni-toring system, and it reduces monitoring costs of greenhouse environmental.
