Study On Farmland Information Transmission And Processing System Based On GSM

The core of precision agriculture is to realize the sustainable development of agriculture, and harvest in economic and ecological benefits with the least investment based on the actual needs of crops. However, research on the technology of communication and information needed greatly by producers. This article introduces such a design of system for the farmers. It has three important functions: gathering most kinds of attribute information from farmland, integrating variety kinds of data, processing and propagating information wirelessly.This paper is one part of a research project with the full name of remote sensing and ground research on precision agriculture (Item Number: 200040712018). On the basis of comparison, analysis and information of technology from home and abroad, also with the use of GPS, SCM, GSM, GIS technology, we designed a long-distance transmission system based on the GSM network in the fields, so that we realized the wireless transmission system. In order to meet the low power consumption and portable design requirements, we established a hardware platform with the SCM as a control center, GPS receiver as positioning equipment, water testing as a field sensor, GSM terminal module as the information media. In the end we completed a hardware design of serial circuits, liquid crystal display circuit, the expansion of communications circuits, small keyboard circuit, power and voltage regulator circuit, and GSM module.The test result of the system showed that it is available on the wireless long-distance real-time transmission. The article also analyzed factors that influence speed of transmission and proposed improvement measures. It provides an efficacious device and technical support for the long-distance live transmission, quick gathering of information, decision-making, as well as the intellectualization control of variable factors.
