The Design Of The MCSEM Upper Monitor Unit On Board

Marine controlled source electromagnetic detection (MCSEM) is the regional geological survey and deep geological structure of one of the important geophysical methods.Research on MCSEM. through abroad, achievements have been made by many waters:the successful test, marine controlled source electromagnetic detection for seabed oil gas distribution of specific geographic graphics filled and seabed resource exploration has created enormous social benefit and economic benefit.In China, because the sea is a layer of high conductivity layer, electromagnetic field of high frequency components of a strong "absorption" effect, which can penetrate the water reaches the seafloor, mainly, the low frequency signal, natural gas hydrates in marine low temperature and pressure environment, utilization and resistivity of wall rock has the obvious difference of resistivity electromagnetic detection method, finding a high resistivity body existence.The project is based on natural gas hydrate of marine controlled source electromagnetic detection system integration technology projects, and undersea transmitter towed body corresponding to, design of marine controlled source electromagnetic deck unit PC monitoring software development, for the undersea transmitter towed body detection provides real-time monitoring effect, and can live on towed body sends control signals, is helpful for seabed oil gas detection and anomaly extraction geographical Graph Expansion and implementation of marine controlled source electromagnetic detection, can be in gas hydrate exploration plays its economic and social benefits. For our country to the seabed oil gas resources exploration and contribution. Marine controlled source electromagnetic transmitter in submarine towed process, through long distance signal line real-time monitoring and control of its working state. In this urgent demand, deck unit monitor software is very necessaryOn the PC technology improvement, in the first stage on the basis of research results, through careful analysis, identify the need to achieve the main technology, implementation of3D real time display of marine controlled source electromagnetic instrument attitude technology, timing transmitting technology, current playback technology, grounding resistance design, the real-time data backup, data storage, classification, separation control circuit set of serial port technology.Labview is a graphical editing language, compared to other language is relatively graphic, visual clear, easy to edit, in the Lab VIEW platform based on the software editor, on the need to achieve a technology to draw a flow chart design, then according to the design idea based on Lab VIEW on the basis of design, and then debugging, until the program is scheduled to complete the index.
