[Abstract]:In recent years, the rapid development of offshore electromagnetic exploration technology in foreign countries has greatly alleviated the pressure of supply and demand brought about by the shortage of terrestrial oil and gas resources, making it possible to open up new resources. With the sustainable development of China's economy, the dependence on oil and gas resources is gradually increasing. Because of the relative shortage of land resources, the development of marine resources becomes very important. Marine controlled Source electromagnetic method (MCSEM) is one of the effective exploration methods for seabed resources. As an important part of MCSEM detection system, marine controllable source deck monitoring system is a good platform for monitoring the real-time working state of submarine electromagnetic exploration. Ensure that the marine electromagnetic exploration system works properly and that transmitter status is recorded in real time. Based on the design requirements of marine controllable source deck monitoring system, and referring to the relevant research data at home and abroad, and according to the design technical specifications and design requirements, this paper introduces the overall design scheme of the marine controllable source deck monitoring system. The key technologies involved are further studied. Based on the real-time, high efficiency and effective planning requirements of the deck monitoring system workstation, and according to the overall design scheme of the marine controllable source deck monitoring system, this paper uses the C # language under the .NET Framework system platform to make use of the multi-thread technology. Socket technology and Ethernet communication technology are applied to the man-machine interactive control software of marine controllable source deck monitoring system. The purpose of monitoring the parameters related to the operation of GPS and transmitter equipment is achieved, and the function of accessing historical data is added. In order to facilitate the monitoring personnel for rapid and accurate seabed resources data information analysis. In this paper, the design of real-time waveform display user control is completed by using GDI drawing technology and the algorithm of data value and coordinate value conversion. The waveform imaging is carried out according to transmitter core parameters such as transmitter current, transmitter towing to submarine height and so on. The designed waveform image user control can achieve continuous rolling display, accurate coordinate display and other display effects, and can realize the functions of multi-waveform display, grid display, image enlargement and reduction, curve drag query and so on. In this paper, the GPS beacon machine is used to obtain the synchronous geographic position information such as latitude and longitude, time, speed, heading, elevation and so on successfully by using the data analysis algorithm. At the same time, the satellite positioning information is displayed and monitored. The coordinate conversion algorithm is used to realize real-time track tracking and monitoring. In order to ensure the validity of monitoring data and the safety of maritime travel, the abnormal warning and warning function is added to the design of waveform drawing module and track monitoring module in this paper. In this paper, the network communication module, waveform display module, track monitoring module and the integrated operation of the deck monitoring system are tested in a large number of rooms and outside. The test results show that the deck monitoring system can meet the design requirements of stable operation, high reliability and high real-time performance through the research of key technology in this paper.
