Research On Agricultural Greenhouse Environment Monitoring System Based On Internet Of Things Technology

In recent years,with the advancement of science and technology,themodernization of China agriculture has also been a rapid development. Inagricultural production management, from initial computer control, and nowInternet of things agriculture, by the way of using Internet of Things technologyagricultural monitoring system more and more been designed. In China, thenumber of rural agricultural greenhouses is increasing, most of the agriculturalgreenhouses is still in labor management. Greenhouses monitoring system usingcomputer technology due to the more wiring, energy consumption, making thecosts of management are too high. Based on the study of Internet of Things, thearticle proposes agricultural greenhouse environment monitoring system basedon Internet of Things technology. According to the structure of things, the systemis designed, at the same time, the system builds wireless sensor networks toachieve the function of collection for greenhouse environmental information bythe way of using of ZigBee wireless technology. Greenhouse environmentinformation includes temperature,humidity and carbon dioxide concentrationsand other environmental parameters. According to the working idea of theperception,transmission,application in the Internet of Things,agriculturalgreenhouses monitoring system based on Internet of Things technology isdesigned. The design of the whole system is divided into two parts. Perceptionand transmission for information is finished by wireless sensor network.The usermonitor terminal finish to receive and display the data. Finally,on the basis ofachieving the function of monitoring data, according to the parameter data whichthe system has monitored,the corresponding regulation equipment is controlledby the sure rule. The main work is summarized as follows:(1)Analysis of the structure of the wireless sensor network, the system design is completed. Design of Hardware and software of sensor nodes and thecoordinator node are introduced. The embedded chip CC2430is selected as themain microprocessor of network nodes.(2)PC handheld terminals and embedded monitoring terminal is designed.PC monitoring terminal is used as the immovable monitoring platform. The PCmonitoring terminal is suitable for working in long time in the control room.Embedded handheld monitoring terminal is mainly used in the case thatgreenhouse managers carry simply and view the data. Embedded handheldmonitoring terminal is a removable monitoring device,so low-power embeddedmicroprocessor LPC2103is selected as the core of the equipment to finish thehardware design of monitoring terminal.(3)According to the changing data of each parameter,adjusting of thegreenhouse environment parameters is researched. In the control rules design forregulate equipment, according to the different variation of parameters,theautomatic control for Regulating equipments is achieved. By the way of usingshutter motor,watering equipment,ventilation equipment and lightingequipment,achieving the regulation of the temperature,humidity,carbon dioxideconcentration,light intensity and other parameters.The main structure of the system is built by the way of adopting Internet ofThings technology. By the way of building wireless sensor networks collectingenvironment information parameters is finished within the greenhouse.According to the monitoring parameter values control of the device is achieved.Design of monitoring terminal is finished by selecting the traditional PCmonitoring terminal and embedded handsets monitoring terminal. Embeddedhandsets monitoring terminal could finish monitoring data in the move.Agricultural greenhouse temperature distribution were analyzed. Debuggingthrough the system, the function of collection, transmission and display ofinformation is realized. Embedded handheld terminal has achieved the functionof displaying data and sending for control commands.
