【摘要】 在双船地震勘探中,双船间距控制及电缆形态实时显示是十分重要的。文中详细介绍了双船实时状态观测系统的方法基础和实现过程。在研究了大椭圆航法的大地主题反解模型的基础上,建立了双船距离控制预警模型。系统采用插件技术进行框架设计,基于.NET Framework、Arc GIS Engine SDK平台,并通过插件接口定制、插件动态加载及插件消息传递等机制实现了工程管理、设备管理、测线管理、双船监控、设置、常用工具、模式、视图8个功能模块。视图部分可设置正常视图、偏移视图、电缆视图、距离监控视图、主副船监控视图、主副船文本视图6个显示视图。海试表明系统能够对双船间距进行有效控制和对电缆形态进行实时显示,并能够长时间稳定运行,极大提高了地震勘探数据采集的质量和精度。更多还原

【Abstract】 In two-vessel seismic exploration, it is important to control the two-vessel distance and show the cable shape in a real-time way. This paper introduces the basic method and implementation process of the double vessel real-time status observing system in detail, and establishes the warning model for two-vessel distance controlling by studying the inverse solution model of geodetic problem on great ellipse nautical method. The architecture of the system is designed with the plug-in technology. Based on the platforms of.NET Framework and Arc GIS Engine SDK, and by using the mechanisms of plug-in interface customization, plug-in dynamic loading and plug-in messaging, the system has realized 8 functional modules, including the project management, device management,measuring-line management, real-time status monitoring, configurations, common tools, modes and two-vessel view management. The system has 6 views, consisting of the normal view, offset view, cable view, distance controlling view, two-vessel monitoring view and two-vessel text view. According to the results of sea trials, the system can effectively control the two-vessel distance and show the cable shape in a real-time way, with a capability of stable and long-duration operating, thus significantly improving the quality and precision of collected data in seismic exploration.更多还原
