Design And Implementation Of The Greenhouse Environment Monitoring System Based On The 4G Network

Facility agriculture is a means to ensure the high-efficiency and growth of the crops by the modern engineering technology which is an important and indispensable part of modern agriculture in a relatively bad growth season for plant to guarantee the normal growth of plants and ensure the production. In the northern region, as the change of season, the change of temperature directly affects the growth of crops by greenhouse which can effectively provide appropriate growth environment for plants. Nowadays, the control of the growth environment of crops in greenhouse has transformed from the traditional personal management mode gradually toward modernization and the unification of the centralized management mode. Highly centralized management can not only effectively reduce the management cost and make a timely and accurate judgment in the shortest possible time but also ensure the normal operation of the greenhouse and guarantee the normal production in the greenhouse crops. However, because of its vast centralization management scope, the greenhouse environment temperature is the basis of greenhouse work. Unfortunately, most common greenhouse environment monitoring system can work in a relatively limited range, thus, which is a difficult problem for centralized management.This paper attempts to take the environmental monitoring system as a research object to design an embedded environment temperature monitoring system based on TD-LTE networks. The core of the acquisition device adopts embedded processor S3C2440 A from the Samsung ARM series which is the core of the whole hardware system. Temperature sensor adopts DS18B20 for the sensor has small volume, strong anti-jamming capability and high accuracy etc. In terms of data transmission, it uses the TD-LTE since it has the high transmission speed, fast response and other advantages. Its server uses LINUX operating system the Red Flag and the trial J2 EE design which is based on B/S of WEB way structure is made as PC software. In this paper, the author tries to write the visual interface in order to realize the real-time dynamic monitoring and early warning function against the ambient temperature. It should be rapid and efficient data transmission service for the greenhouse environment temperature monitoring system in a unlimited range by offering universal coverage in such a wireless transmission way.
