Design And Implementation Of Greenhouse Meteorogiea Remote Wireless Data Acquistion System

Since the reform and opening up, China’s agricultural research applied technology more and more attention, especially the rapid development of the greenhouse temperature has become an important part of modern agriculture. Greenhouse is an important part of some important parameters of greenhouse environment monitoring and control, real-time acquisition of these environmental parameters can effectively promote the rapid development of precision agriculture.Demand for the collection and transmission of data greenhouse meteorological elements proposed in this paper based on the AVR and GPRS Greenhouse meteorological elements remote wireless acquisition systems, data acquisition using ATmage64 end micro-controller, using temperature and humidity sensors, pressure sensors and other sensors to achieve the greenhouse meteorological elements data collection, and data transfer between the field and GPRS modules via RS232 mode using GPRS module for remote data transmission effectively solve the problem of remote monitoring data acquisition, the realization of greenhouse centralized management.This design is based on the AVR and GPRS wireless remote meteorological elements greenhouse acquisition system uses solar power to achieve a rational use of green energy, while the implementation of a variety of data to show the way, making on-site and remote management personnel can simultaneously observed data. System includes four parts data acquisition, GPRS remote transmission units, data centers receiving unit and a display unit, which is responsible for real-time data acquisition of various meteorological elements data collection site; GPRS remote transmission unit is responsible for remote data transmission; Data Center Data is responsible for accepting all sub-stations and data storage processing, data acquisition and analysis simple, given some of the elements that day maximum, minimum, maximum and minimum values; data display unit including on-site data acquisition in real-time data transmitted via RS232 mode LED screen, laptop-site real-time acquisition and display and save the data curve represents data, also includes a Web browser-side data real-time display and curve represents, thereby helping the user can View real-time data anytime, anywhere through the network, user-friendly real-time management.Lower data communication between the host computer and the remote machine via GPRS wireless TCP protocol transparent transmission, completely solved due to the geographical differences are not caused by centralized data management problems. This article based on the AVR and GPRS wireless remote meteorological elements greenhouse collection system through on-site installation and commissioning, to prove this design system has good stability and real-time implementation of the system has a good social and economic benefits.
