摘要
针对目前农业大棚监控和管理存在的一些问题,设计了一种基于物联网的农业大棚监测系统。利用无线传感节点采集温度、湿度、二氧化碳浓度和光照强度,并对这四种数据进行初级融合,将初级融合后的数据通过无线传感器网络汇集到数据中心;数据中心将汇集后的数据进行二次融合后打包送到PC机和移动终端,大大方便了用户的管理。此外,利用数据残差对环境因子进行分析,判断大棚内环境状况,为农业大棚的维护和管理提供及时有效信息。
In view of monitoring and management in agricultural greenhouses, developing a set of ag- ricultural greenhouse monitoring system based on the Internet of Things. Wireless sensor nodes cap- ture the temperature, humidity, concentration of carbon dioxide and illumination intensity, then the system is responsible for junior fusion of those data and transmitting junior data to the data center through wireless sensor network. The data center is in charged of senior fusion of all the pooled data and transmitting senior fusion packets to the PC machine and mobile terminal, which is greatly con- venient for the management. In addition, applying residual to analyze the environmental data and determine the state of the greenhouse, useful information can be provided to the maintaining and man- aging agricultural greenhouse.
