Research Of The Greenhouse Environment Monitoring System Based On Internet Of Things

In recent years, due to the good economic benefits of greenhouse, research ofgreenhouse has developed rapidly, especially the monitoring of greenhouse environmentparameters. The foreign crop growth monitoring began in the1970s,, rapid pace ofdevelopment, especially in the developed countries of Europe and the United States, suchas the Netherlands, the United States realized mechanization. With the rapid developmentof information technology, some developed countries have achieved the real-timemonitoring and automatic control of greenhouse, also conducted application and researchof artificial intelligence. Network technology, telemetry, and expert system wereintroduced into the monitoring system truly remote monitoring, unattended and fullyautomated.China is a large agricultural country, agriculture is the state’s essential, therefore,monitoring of the environment for the growth of crop is particularly important. Traditional,inefficient mode of agricultural production can’t meet the requirements of safe,high-quality, efficient, productive modern agriculture. With things technology is introducedinto the field of agriculture, the industrialization of agriculture and information technologyappears unprecedented opportunities. Agricultural information mainly focus on thefollowing aspects to be undertaken, including the development of modern agriculture, toenhance the scientific and technological level, transformation of mode of agriculturalproduction, to meet the high-quality, high-yield, efficient, ecological and safetyrequirements, agricultural modernization become the development trend of the future ofagriculture. The Internet of Things will be the short-range wireless transceiver deviceembedded in devices and daily necessities, so that persons and things, between thingsanywhere able to communicate with each other, so as to constitute with respect to theInternet in terms of the broader network. Internet of Things technology applied togreenhouse environmental monitoring system, the establishment of based on Internet ofThings technology greenhouse environmental monitoring system, providing reliableenvironmental monitoring data for peasants and monitoring personnel, to help farmers totake timely and effective measures, the production of agricultural products andsocio-economic development has important practical significance.This article analysises of the three-tier framework structure by Internet of Things ofperception layer, transport layer and application layer, and uses of the Internet of Things, designs based on Internet of Thing greenhouse environmental monitoring system. In thispaper, TD terminal is used to data collection including the parameters of the indoor airtemperature and humidity, soil temperature and humidity, CO2concentration, light intensityand other environmental factors; TD-SCDMA wireless communication network is used todata information transmission, the final data transmission to the monitoring center;monitoring center is responsible for data analysis, processing and storage. The monitoringcenter software development environment is Microsoft Visual Studio2008, databasesystem design uses SQL Server2005, integration and analysis of data uses data fusiontechnology.This article gets the following conclusions:（1）TD terminal is used for data acquisition and TD terminal integrates monitoringrequired for various types of sensors, wireless communication module TDM330andmicroprocessor S3C2410to achieve real-time monitoring of environmental parametersconduciving to real-time data transmission.（2）Using TD-SCDMA technology for wireless communication, protects the securityof data transmission; due to the reduction of the interference of the external environment,thereby improving the stability of the system.（3）Application of the adaptive weighted average data fusion technology and SQLServer database technology, approving the capability of system processing of data; usingmodular design easily system late expansion.
