Based On The LabVIEW Electric Railway Electromagnetic Radiation Detection And Processing System

In recent years along with the development of China’s high-speed rail,electrified railway electromagnetic radiation problem is becoming more and more attention by scholars.Although the scholars on issues related to a lot of theoretical research and laboratory simulation, have also made many valuable experimental data, but the lack of the scene of the actual test data is still a problem needed to resolve.Is based on this, the author wants to put forward a fast feasible acquisition system, and through the mathematical method to analyze large amounts of data,to get reliable test data.This topic design system is the application of the concept of virtual instrument to the existing acquisition equipment, using computer software to realize the control of the equipment and data acquisition and processing.On the one hand, can be set through the computer software to collect equipment and operation control, on the other hand, Under a machine to collected data can be stored on a computer, display and analysis, all user actions on the computer.System selection based on G language Lab VIEW as the software development platform, design of upper computer software program to complete, according to the signal processing, analysis and testing in different environment, can be directly set the related parameters on the software has reached the requirements of the test.Signal data were collected at the same time to make, can better response measured actual situation, can be saved to the computer figures out that through good system design in advance some filter module for data processing.Also can call the Math Script program, read the corresponding algorithm to the data processing program code, and generate a spectrum analysis.Finally, the paper for the whole system running stability and reliability of the laboratory testing, reached the expected design requirements.Waveform were collected at the same time, with the original waveform figure on theacquisition equipment basic trend is the same, after dealing with the data of spectrum is consistent with the theoretical scope of relevant research.System to achieve the multi-channel data collection and rapid collection, improve the efficiency of the measurement, and for electrified railway electromagnetic radiation measurement provides an effective feasible solutions.
