| High Precision Draft Cable Collection System of China Oilfield Services Limited (COSL) is a stable and reliable, easily operational and maintained software, in order to better achieve 16 cables seismic data acquisition and control, real-time transmission, processing, storage, record and Quality Control (QC) monitoring function. Meanwhile, it is designed in order to better meet the high-precision draft cable seismic data acquisition system and the expansion of the forward-looking, norms and maintainability. This system is mainly used cross-platform C++, graphical user interface-Qt toolkit and ANSI C for development. The whole system is using object-oriented design idea and the code meets the standards with ANSI C.The paper compared the technology characteristics of mainly used parallel programming languages, including Message Passing Interface MPI, the Multi-thread technology-OpenMP and the Win32 thread library, which is suited to use on the Multi-core platform. Based on the comparison, according to the requirement analysis, the paper finally chose the Multi-thread technology to do the real time parallel processing of massive seismic data, and designed a parallel solution. Afterwards, the paper issued the main framework design of the draft cable system, which is composed of three modules- the system control system module, the data processing system module and the QC monitoring system module. According to the parallel solution, I designed and implemented the data processing module in the data processing system. Meanwhile, I designed and implemented the data collection module in the data processing system, the day-month check analysis and the data processing module in the QC monitoring system, and gave the test result of the system.With the release of the draft cable collection system, it will provide effective technology support for the COSL's draft cable collection project in sea, improve the COSL's core competitiveness in this field. |
