Research About Multifunctional Data Interpretation System Of Electrical Method

Electrical prospecting is a widely applied engineering geophysics method. Many data interpretation systems were developed in practical applications, but they were single function, a project may need various kind of electric interpretation system, and generality poor, aiming at special instrument. The pape in detail illustrates the research method and realization process of multi-function electric interpretation system based on the introduction of Electrical prospecting knowledge.Firstly, according to the understand of present electrical prospecting, acquisition data of direct current electrical sounding and transient electromagnetic were determined as our system interpretive object. And introduced basic principle and working method of these two electrical prospecting.Secondly, requirement analysis and structure design of multi-function electric interpretation system is carried out in system designing process. The system has been divided into four component modules: data communication module, system management module, data processing module and drawing module. The system can receive data of various kind of instuments like direct current electrical sounding and transient electromagnetic, before inversion interpret, compile received data to generate inversion interface file, then calculate the file by forward modeling and inversion fitting, eventually obtained precise geological construction condition.Finally, based on above research achievements, under the environment of DELPHI development platform build the main frame of multifunctional electrical data interpretation system, some interfaces for further development were reserved in the develop process. The experiment result show the system relized interpretation of various kind of electric data, obtained geological construction condition of measurement area, possessed main function of electric data interpretation.
