Design And Implementation Of ERT Pollution Monitoring Data Analysis System

In recent years,China's economic level and industrial production level have been constantly improved.However,due to the weak environmental protection awareness of enterprises and individuals in the early stage of industrial production,a large number of pollutants have entered the soil,causing serious soil pollution in China.In order to carry out the treatment of contaminated soil,first of all,it is necessary to carry out pollution detection to clarify the scope and degree of pollution.Due to its advantages of simplicity and high efficiency,Electrical Resistivity Tomography(ERT)technology has been gradually applied in the field of environmental pollution monitoring in recent years.However,at present,a complete ERT pollution monitoring system has not been formed,and there is a lack of effective monitoring data processing methods.Therefore,it is of great significance to research and develop an ERT pollution monitoring data analysis system.First of all,this paper describes the current situation of soil pollution in China and ERT soil pollution monitoring technology in detail,analyzes the demand for ERT monitoring data analysis system,and designs the function of the system based on the analysis results.The main functions of the system include checking the actual situation of the project,ERT\ geochemical data analysis,ERT image processing,ERT data processing,system parameter settings and registration and login.Then,in view of the pollution area in the ERT monitoring data analysis to identify the difficulties,this paper established the contaminated site model,studied a variety of typical data and image processing algorithm is used in the pollution area,and the experimental results show that the ERT image,a two-dimensional image threshold segmentation algorithm is compared with one dimensional image threshold segmentation algorithm is higher identification accuracy;For ERT data,FCM algorithm has higher recognition accuracy than K-means clustering algorithm.Finally,the system uses.NET framework as the main framework of the system,SQL Server as a data management tool to achieve data storage and management,through the AMAP API to achieve the display of the location of the site and the survey line;C# programming language is adopted as the main language for program development and design,and Python and other programming languages are combined to complete data analysis and processing functions.The system test shows that the ERT pollution monitoring data analysis system designed and developed in this paper can realize the collection,storage and management of contaminated site monitoring data,and provide multiple data processing methods to analyze and process the monitoring data,with a stable and reliable operation.
