Design And Implementation Of Portable Automatic Weather Station Maintenance Terminal

The automatic weather station is the main equipment used by meteorological departments for continuous observation of atmospheric conditions.Due to the rapid development of meteorological detection automation,the Local Meteorological Bureau stations in the country have basically established the regional automatic meteorological station encryption monitoring network.Not only this,but also the number is increasing gradually.This not only provides the weather forecast to provide more refined detection data,but also to scientific research.The study provides the guidance of the theory,at the same time,for the grass-roots Meteorological Bureau,the equipment operation and maintenance work,put forward a greater challenge,especially for the automatic weather station data collector,there has not been a more convenient test and maintenance equipment.In this way,it is more urgent and practical to design and develop a convenient,friendly and powerful test terminal,and also to carry out real-time data analysis,real-time data collection,proofreading,and to implement the portable maintenance terminal of the storage automatic weather station data collector.In this paper,the practical significance and purpose of developing the handheld meteorological test terminal at the present stage are analyzed.At the same time,the development of handheld devices is also studied.Finally,the research direction and ideas about the handheld meteorological test terminal are determined on the basis of ARM.Next,the theory of system development and the key technologies in development are studied in detail.On the basis of embedded theory research,hardware and software solutions are designed.The main contents of hardware design are:processor,power supply circuit,display interface circuit,USB interface and other circuits.The main contents of software design and implementation include:software function requirement analysis,overall design,decomposition design and troubleshooting of each module.The four main modules of serial port communication,wizard flow,inspection process and remote management are introduced in detail.Finally,the complete test of the terminal system is carried out,and the test situation is analyzed and processed to find out the shortcomings and improve the shortage.In the process of system design,software design and development,this paper has done a lot of work,and finally completed the design and implementation of the maintenance terminal of the portable automatic weather station data collector,and achieved the ideal effect in the application and popularization of the follow-up business...
