Design Of Electromagnetic Environment Monitoring System Based On Smart Phone

With the rapid development of communication technologies and the large-scale construction of carrier base stations,the space electromagnetic environment has become increasingly complex,and electromagnetic radiation pollution has become increasingly serious.Currently,traditional electromagnetic monitoring methods are mostly concentrated in the professional field,which makes people have no scientific understanding of electromagnetic radiation,and there are always some"misunderstandings" about electromagnetic fields.So many social problems caused by such misunderstandings abound.At the same time,in the era of big data,the statistical analysis of large-scale data in the electromagnetic environment of the space is of great significance to the healthy and stable development of the electromagnetic environment,and is in line with the strategic goal of sustainable development in China.This paper proposes a design method of electromagnetic environment monitoring system based on smartphone that can perform data collection on the mobile terminal,storage and analysis on the server,and display on the web.The main work of this paper is as follows:1.Based on the development of the current electromagnetic environment monitoring field and the remaining problems,the overall design of the electromagnetic environment monitoring system based on smart phone is proposed,including the system user needs and feasibility analysis,main design principles and requirements,and system framework and technical route.2.In the introduction of the electromagnetic data information collection module,the software function of the collection module is first determined,through comparison and selection,the development mode and development framework of the APP and the code of the key functions implementation is described.The serial port development method of the spectrum analyzer is introduced.3.In the introduction of electromagnetic data information processing module and display module,the background development mode and electromagnetic information database are compared and selected firstly,the development mode of PHP+Apache+MySQL is determined,and the code of key functions is introduced.Secondly,the method of Baidu map api and ECharts component in the display webpage is introduced.4.According to the established functions and objectives of the system,the display and usage of each page of the system are introduced,and the overall data communication capability test of the system is carried out.The comprehensive test results are given.Finally,the practical application of the system are given:the application of popularizing the correct "electromagnetic view" and the application in the big data analysis of electromagnetic monitoring.Based on the popularity of current smart phones,the system can be used as an effective supplement to professional electromagnetic monitoring.Because it is almost independent of monitoring conditions,people can actively participate in monitoring and understanding electromagnetic field.The promotion of the system can obtain a large amount of electromagnetic monitoring data on a large spatial scale and time scale,which is helpful for statistical analysis of large data in the electromagnetic environment.Therefore,the use of this system has a considerable application value in electromagnetic environment monitoring.
