China is a large agricultural country.The promotion of greenhouse is an important measure for the development of agricultural modernization in China.At present,most of the greenhouse lighting measures for the environment are mainly incandescent lamp or energy saving lamp,which not only consumes a large amount of energy,but also causes the oversupply of plants to inhibit the growth of plants.LED light array is the most basic light source with LED lamp,and the source of LED lamp has no pollution,cold light source,low energy consumption and so on.So using LED lamp light source is a kind of environment-friendly economic supplement,and is also widely welcomed by farmers.Agricultural Internet of things is the combination of Internet of things and traditional agriculture.It can optimize resource allocation,and it can be widely promoted in greenhouse,farming and other agricultural technology.The combination of the Internet of things and the LED array can provide more support for the establishment of a scientific,practical,simple and convenient management platform for the greenhouse information system.In order to solve the problem of insufficient or oversupply in greenhouse,this paper combines with the technology of Internet of things,and constructs a greenhouse LED monitoring system based on the data collection,data transmission and data processing,which is based on the Internet of things in the greenhouse LED.The data acquisition part mainly uses light intensity sensor,single chip microcomputer and peripheral circuit to realize the data acquisition of light intensity.The data transmission part mainly uses Zigbee technology and GPRS technology to realize the packaging and transmission of the data.The data processing part realizes the preservation and analysis of the data,and creates the management platform of the greenhouse LED light plant light monitoring system,which realizes the monitoring and adjustment of the amount of light,so that farmers and farmers are more aware of the situation of greenhouse lighting.The following conclusions are obtained in this paper:(1)Based on the planting information of greenhouses and the analysis of domestic and foreign greenhouse light-up technologies,combined with the current status of nonuniform light in greenhouses,an information collection system based on STC89C51 and BH1750 FVI light intensity sensors was constructed.(2)The use of Zigbee technology and GPRS wireless communication technology to complete the far and near distance transmission of data in the greenhouse,to achieve the sharing of information in the greenhouse and to facilitate farmers and farmers in real-time view.(3)Using the combination of expert system technology and particle swarm optimization(PSO)to complete the process of data processing in the greenhouse,the optimal LED light bead combination and the optimal number are achieved to meet the current lighting conditions,and the optimal supplement of greenhouse crops is realized.
