Design And Implementation Of Automatic Weather Information System Based On Embedded Technology

The demand for meteorological prediction is getting higher and higher in residential and industrial production,and the accurate weather forecast depends on the high precision and stable meteorological observation data.Therefore,in recent years,the meteorological observation equipment has put forward higher requirements.However,it is difficult to maintain the weather stations in the vast area of our country,or the personnel are difficult to survive for a long time.The collection of meteorological data makes the time density and space density of meteorological data difficult to meet the need of accurate prediction.In recent decades,with the development of electronic information and computer technology,an automatic unmanned meteorological station has emerged gradually,which is unattended and often maintained.It has solved the problem of difficult maintenance and data acquisition for some meteorological stations in the traditional weather stations.With the development of embedded system software and hardware technology,it is possible to apply it to the field of meteorological monitoring.Therefore,the automatic meteorological station,with embedded system as the core,has been paid more and more attention in the world of meteorology.In this paper,the automatic weather station is analyzed and introduced in detail,and the research status at home and abroad is deeply analyzed and discussed,and some automatic meteorological station series,which are widely used at home and abroad,are listed.At the same time,it points out that there are some problems such as low degree of openness,poor compatibility between different manufacturers,poor expansion and dependence of main components on imported automatic weather stations.According to the development status of China's automatic weather station and the actual situation in China,a multi element automatic weather station system is designed by using STM32 MCU and GPRS technology,in order to reduce energy consumption and improve performance.The requirements of the system software are analyzed from two aspects of main functions and composition and structure,and the design scheme of hardware and software for the embedded automatic weather information system is determined.The hardware system and software system are designed in detail.The hardware system is mainly selected and designed for its main control module,meteorological element collection module,communication module,data storage module,human-computer interaction module and other modules,and the embedded software is elaborated in detail based on the result of hardware design.The mechanism is realized,and the software of the data acquisition and processing module,the data storage module,the human-computer interaction module and the communication system are designed in detail and the program is compiled.Finally.the embedded automatic weather information system is designed,and the system has passed the test of various functions smoothly.Through this study,some shortcomings of the traditional meteorological station information collection system have been overcome,and the automation of information collection,processing and transmission has been realized,and its practicality is greatly improved.It also has the advantages of small volume,low energy consumption,fast acquisition and processing speed and low cost,which conforms to the future development of China's meteorological monitoring field.Direction and wide application prospect.
