Design Of Intelligent Greenhouse Monitoring System

As a big agricultural country,China’s realization of agricultural modernization is the only way to develop.New agricultural science and technology is also an important task for China’s agricultural development.The emergence of intelligent greenhouses can not only improve the impact of different climatic conditions on crops in different regions,but also provide optimal growth environment for crops by monitoring environmental factors,achieving efficient and continuous crop production,and improving land utilization.An effective way.The location of this study is Xinjiang Alar,which is a typical continental climate with a dry climate,large temperature difference between day and night,large evaporation and scarce rain.The local economy is dominated by agriculture and the economy is underdeveloped.The greenhouse monitoring system currently used is mainly based on the introduction of a complete set of intelligent greenhouse systems in developed countries.There are still many areas for improvement in practical applications.Greenhouse environmental monitoring is an essential condition for the normal operation of the greenhouse and a basic link for studying the crop growth environment.The use of new sensors and Internet of Things technology to achieve a comprehensive,high-precision,high-reliability,uninterrupted data collection is essential.It is also the basis for big data and artificial intelligence to realize smart agriculture.(1)Using the new sensor to achieve high-precision,low-power online collection of key indicators such as temperature and humidity,light intensity and carbon dioxide concentration in the greenhouse,modular design for power supply and communication,and judgment of the collected parameter values.Or alarmed by an audible and visual alarm when it is below the parameter value range.(2)Judging the effect of some collection parameters through time and environmental conditions to achieve dormancy in some time periods,mainly by using two kinds of precisionrecording mode,time recording node control,environmental condition judgment to collect data,reduce power consumption,reduce data The storage space reduces the communication pressure,and in the future,the number and type of sensors can be increased as needed to further improve the reliability of the collected data.(3)Through the connection of ZigBee wireless network with sensors and gateways,the multi-source-aware node networking model of environmental parameters is realized,and a system for monitoring environmental parameters of large greenhouses or cluster greenhouses is constructed.The environment parameters can be displayed on the host computer and the gateway in time,and the data is uploaded to the cloud to complete long-term data collection and historical record query.Real-time monitoring of greenhouse environmental information is realized by using related technologies such as the Internet of Things,and the device has the characteristics of low cost and easy use.(4)In order to improve the service convenience of the greenhouse monitoring system,this paper also designed and developed the APP mobile monitoring platform based on Android system,and collected the real-time monitoring of the collected data,which greatly improved the convenience of monitoring.The actual operation results showed that:monitoring The system has the characteristics of stable operation and simple operation.The system basically meets the requirements of low cost,wireless,intelligent and precise to meet the needs of greenhouse intelligent monitoring.
