Field Information Remote Acquisition And Wireless Transmission System Design And Development And Precision Analysis

In recent years,the concept of "precision agriculture" has gradually become the main development direction of agriculture.Its content is to make reasonable field management decisions according to the actual situation and needs of crops,adjust the field environment to a good state,obtain more yield with less input,and reduce the damage to the ecological environment.This concept is very much in line with the theme of modern green agriculture,and accurate field information is an important basis for workers to make field pre dictions.With this information,people can judge when to provide irrigation and where to apply fertilizer,so as to achieve the goal of agricultural fine management.Therefore,this paper combines the idea of precision agriculture with information technology,and studies the application of information collection and transmission in agriculture.In order to accurately track the real-time situation of field crops,this paper combines sensor technology,single-chip microcomputer technology and GPRS technology,proposes a design scheme of field information remote acquisition and wireless transmission system,and establishes a field remote monitoring system.The system has the function of real-time acquisition and transmission of field information,and can be operated in the field environment without people,realizing remote monitoring.The modular design method is applied to the field remote monitoring system,which is mainly divided into four parts:environment information acquisition module,data wireless transmission module,power supply module and computer remote monitoring center.In the environmental information acquisition module,the sensor supports the collection of field soil temperature and humidity,wind speed,wind direction,light and other informati on,and the SCM completes the processing operation of the collected data.In the data transfer module,the data is transmitted by GPRS.In the power supply module,two power supply modes,solar energy and battery,are adopted to jointly provide power for the system and ensure the normal operation of the system.In the design of the computer remote monitoring center,the data can be stored and analyzed,and the remote monitoring and control of the system can be realized.The design of the system focuses on data acquisition and transmission.After the completion of the design,according to the data collection of soil temperature and soil moisture,the method of drying and thermometer were compared with the data measured by the system to verify the accuracy of the system.The system can provide a basis for field managers to make the next prediction and the best judgment,lay a foundation for the future development of agricultural information,and play a technical role in promoting precision agriculture.
