【摘要】：海上溢油事故频发,能够第一时间掌握溢油监测信息,及时合理地安排应急处置工作,是最大程度减少国家损失的必要条件。在海上作业平台安装溢油监测系统,基于无线网络传输设备,将作业平台上采集、分析的数据传递至岸基应急指挥中心数据库,构建海上组网式溢油监测体系,能够使岸基指挥中心实时获取平台周围的溢油信息,为溢油事故应急处置和安全监管工作提供有效的数据基础,是海上石油开发作业顺利进行的保障。 基于海杂波特性,航海雷达可以探测海面溢油信息,是目前最有效的溢油监测技术手段之一。它可以不受夜间或者云雾雨雪等恶劣天气的影响,具有全天时、全天候、大范围监测溢油的能力。本文根据航海雷达溢油监测原理,从需求分析、数据库设计、系统设计、软硬件架构、功能设计和实现角度,对海上固定雷达组网式溢油监测体系进行了详细阐述。首先将CARIS HPD源数据库中电子海图数据进行ArcGIS格式下的转换,作为课题研究的基础。再将航海雷达进行固定式安装,应用Spx雷达信息采集技术、ArcGIS Engine二次开发组件、网络传输技术、ArcGIS Server网络地图发布技术和ArcGIS SDE空间数据库引擎,进行数据采集、数据分析、数据传输、数据应用展示四个子模块的功能设计与实现。 本文提出采用坐标转换、地图投影、空间配准、动态分析、空间要素生成等手段,在电子海图基础上构建溢油轨迹回放模型,直观展示事故发生后的溢油漂移轨迹,为海上事故责任鉴定和漂移趋势研究等工作提供技术依据。 针对数据发布功能,以数据优化、混合切片方案优化、比例尺方案优化、多地图服务叠加、灵活运用按需缓存策略等综合手段,有效提升ArcGIS Server网络地图服务和溢油数据发布的性能。
[Abstract]:Frequent oil spill accidents, the ability to master oil spill monitoring information in the first time, and the timely and reasonable arrangement of emergency disposal are the necessary conditions to minimize national losses. The oil spill monitoring system is installed on the offshore operation platform. Based on the wireless network transmission equipment, the data collected and analyzed on the platform are transferred to the database of the shore-based emergency command center, and the offshore network oil spill monitoring system is constructed. The offshore command center can obtain the oil spill information around the platform in real time and provide an effective data base for the emergency disposal and safety supervision of oil spill accidents. It is the guarantee for the smooth progress of offshore oil development. Based on the characteristics of sea clutter, marine radar can detect oil spill information on the sea surface, which is one of the most effective monitoring techniques. It can not be affected by bad weather, such as night, cloud, rain, snow and so on, and has the ability to monitor oil spill all day, all weather and on a wide scale. According to the principle of marine radar oil spill monitoring, this paper describes the netted oil spill monitoring system of marine fixed radar in detail from the point of view of requirement analysis, database design, system design, hardware and software architecture, function design and realization. Firstly, the conversion of electronic chart data in CARIS HPD source database in ArcGIS format is taken as the basis of the research. Then fixed installation of navigation radar, the application of Spx radar information acquisition technology, ArcGIS Engine secondary development module, network transmission technology, ArcGIS Server network map publishing technology and ArcGIS SDE spatial database engine, data acquisition, data analysis, Data transmission, data application show the four sub-modules functional design and implementation. In this paper, by means of coordinate transformation, map projection, space registration, dynamic analysis and spatial element generation, a model of oil spill trajectory playback is constructed on the basis of electronic chart, which can display the oil spill drift trajectory directly after the accident. It provides technical basis for marine accident responsibility appraisal and drift trend research. According to the function of data release, the methods of data optimization, mixed slicing scheme optimization, scale scheme optimization, multi-map service superposition, flexible use of on-demand cache strategy, etc. Effectively improve the performance of ArcGIS Server web map service and oil spill data release.
