摘要
为解决传统农业环境监测仪器在使用中存在的问题,设计一套实用的基于物联网技术的环境监测系统,以实现物联网技术在农业中应用。该系统由农田无线监测网络和远程数据中心2个部分组成。无线监测网络利用ZigBee网络与GPRS/3G/4G网络、Internet相结合,设计具有GPRS/3G/4G和Internet接口的传感器网络网关;传感器节点检测空气温湿度、光照度、土壤温度、二氧化碳浓度及土壤水分,土壤盐分等参数实现环境监测的局域采集与广域覆盖功能;采用Java、ASP.NET和数据库技术构建了农业环境监控中心,实现环境监测数据在互联网上的共享。示范应用表明,该系统能够节水20%~50%,节电10%~30%,减少大量人工作业。基于物联网技术的环境监测系统在生产应用上运行稳定、可靠,具有推广价值。
The practical environmental monitoring system based on internet of things is built to realize application of internet of things in agriculture for solving the existing problems in application of conventional agricultural environmental monitoring equipment. The practical environmental monitoring system based on internet of things includes two parts of wireless monitoring network and remote data center. The wireless monitoring network with the sensor network gateway of GPRS/3G/4G and Internel interface is designed by using ZigBee network, GPRS/3G/4G network and Internet. The parameters of air temperature and humidity, light intensity, soil temperature, CO2 concentration, soil moisture and soil salinity detected by the sensory nodal joints can be collected in local area and covered in wide area to realize environment monitoring. The agricultural environment monitoring center built by using Java, ASP, NET and database technology can realize the share of environment monitoring data on Internet. The demonstration results show the built environmental monitoring system can save 20% -50% water and 10-30% electricity, and reduce a lot of manual operation. The environmental monitoring system based on internet of things with the stability and reliable operation property can be popularized in agricultural production.
