The Design And Development Of MCSEM Data Monitoring System Based On The Object-relation Model

Marine controlled-source electromagnetic method(MCSEM) is an effective method to detect the deep-sea resources. MCSEM data monitoring system is an important part of MCSEM exploration system. During the exploration of MCSEM,the complex detecting environment and exploration process require the data monitoring system has a stronger reliability. Data monitoring system can communicate with multiple peripherals, can achieve the dynamic tracking about the exploration systems, can receive deep-sea working parameters, and the storage of receive data fast, analyses of the submarine oil reservoir using real-time data rapidly.Above all,according to the MCSEM exploration environment and the process,this paper designed a MCSEM data monitoring system based on the object-relation model. This model which has a “high cohesion and low coupling” can avoid the high internal coupling of the traditional model. This design not only increases the reliability of the monitoring system, but also improves the maintainability of the system. The data monitoring system needs to communicate with transmitting system,ultra short base line and GPS.In order to realize the synchronous about communicate and image monitoring. This paper uses multithread technology to avoid the conflict about the system and to ensure the instantaneity of the receive data. Using stored procedure which can optimize the data access efficiency to improve the data storage speed. MVO curve which is the rapid quantitative analysis method is used to analyses the underwater electrical structure by numerical simulation. In order to make the MVO result more exactly, this paper explores the influence of the window size, the result of the MVO curve can help the geologist make decision.This paper gives a lot of experiments or the system function, the results show that every module of the system works coordinately with others, every function works properly. The system can communicate with others, can read the data accurately, the speed of data storage in less than 5s, the data monitoring system can draw the MVO cure. This system has been experimented in the sea, facing to the instability of the real seabed, the system which shows a strong adaptation can meet the functional andperformance requirements, the experiment in the sea verifies the effectiveness and practicability of the object-relation MCSEM data monitoring system.
