Development Of Central Workstation Software System For Seismic Prospecting System

The central station software system is the central core of seismic exploration system, the software control the set of seismic data acquisition network, recording the exploration trajectory geographic information, dealing with the exploration data, and managing the exploration database.Therefore, the central station software system development has been one of important content of the research and development of seismic exploration system.The central workstation software system is developed based on the land seismic exploration system in this paper. The software adopts modular design method which includes communication server system, geographical information system and seismic data processing system. The communication server system, in allusion to the features that there are large amount of clients and concurrent transmission in the seismic exploration, the server system is designd based on the completion port model and develop a reliable network transmission mechanism based on the TCP/IP protocol. The Geographic information system which combine the central station and seismic collection station realize the differential positioning based on the research of single point positioning, and realize the visualization of geographic information. Seismic data processing system use database technology to realize the reliable storage of the seismic data, and carry out the seismic dead traces processing technology using tandem clustering algorithm, finally the effectiveness of the algorithm is verified by experiment.After complete the system design, the central station software system has been applied to field exploration test, the test results show that the software system is stable and implements the function requirement, which successfully established a land seismic exploration system software platform.
