Key Technology Research On Deck Monitoring Sotfware Of Marine Electromagnetic Transmitter Operating Parameters

In recent years, foreign marine electromagnetic survey techniques have beenrapidly developed, which eases the supply and demand pressures brought by theconstrains of land resources on a large degree and makes it possible to develop newresources. With China’s sustained economic development, the dependence on oil andgas resources increases, due to the relative shortage of land resources, thedevelopment of marine resources is becoming very important. Marine controlledsource electromagnetic method (MCSEM，Marine Controlled Source ElectromagneticMethods) is one of the effective means of undersea exploration and it has strongcapacity of discernment combined with other means of exploration aiming at oil andgas resources in the seabed. As the important part of MCSEM detection system,Marine controlled source electromagnetic deck monitoring system becomes a goodplatform to monitor the undersea exploration in real time. This paper studies its keytechnology to ensure that the marine electromagnetic survey system can workproperly and record transmitter status in real time.Based on the marine controlled source electromagnetic deck monitoring systemstheory, this paper refers to domestic and foreign research data. According to thedesign of specifications and the characteristics of requirements, this paper proposesthe all design of marine controlled source electromagnetic deck monitoring systemoverall design, and the key technologies related to the further study.Based on the design requirements of marine controlled-source real-time deckmonitoring system on efficiency and effectiveness, in accordance with the overalldesign of the MCSEM deck monitoring system, this paper uses C#as thedevelopment environment under the.NET Framework platform, writes a HCI controlsoftware on the MCSEM deck monitoring system with the Multi-threaded, Sockettechnology, Ethernet communication technology and other technologies, to meet thepurpose of monitoring relevant parameters about GPS and transmitters equipment during its work runtime and adds the fast and accurate functionality to accesshistorical data monitoring for the seabed data for analysis.This paper uses GDI+graphics technology, data value and the coordinate valueconversion algorithm to complete the user controls’ design of real-time waveformdisplay, and imaging the transmitter core parameters (current transmitter, the height oftransmitter body dragged to the bottom). It uses GPS and the data analysis algorithmto get the latitude successfully, longitude, time, speed, heading, elevation and othersynchronization location information, at the same time with surveillance satellitepositioning information displayed. According to the geographic location information,it can realize the tracks’ real-time tracking using coordinate conversion algorithm. Inthis paper, the abnormal alarm function is added in waveform drawing module andtrack monitoring module, to ensure the safety and effectiveness of maritimesurveillance data travels.This paper has performed many indoor and outdoor tests on the networkcommunication modules, waveform display module, track monitoring mode and theintegrated operation of the system. The result shows that this system can achieve astable, high-reliability, timeliness and strong design requirements by key technologythis paper proposed and meet the design standards.
