Description

Offshore converter station data management method and system Technical Field The invention relates to the technical field of data management, in particular to a data management method and system for an offshore converter station. Background Along with the transformation of the global energy structure to cleanness and intellectualization, the direct current transmission technology is widely applied to scenes such as transregional energy allocation, offshore wind power grid connection and the like, an offshore conversion platform is used as a core hub for offshore new energy grid connection, and the digital and intelligent operation and maintenance level directly determines the stability and safety of energy transportation. Under the large background of the industry, in order to realize the accurate management and control of the full life cycle of converter station equipment, a multi-dimensional sensing monitoring system is generally assembled on power equipment in a converter station, and meanwhile, multi-type monitoring terminals such as a high-definition camera, an infrared sensor, an electric meteorological sensor and the like are deployed, so that massive multi-source heterogeneous data including megahertz-level high-frequency equipment state data, static low-frequency equipment account drawing data and unstructured high-definition video image data are formed, and a high-fidelity full-station three-dimensional scene model also becomes the core configuration of a digital platform of the converter station, so that visual equipment and scene visual support is provided for operation and maintenance personnel. Focusing the subdivision application scene of the offshore conversion platform, the management requirement of data and three-dimensional resources is more severe than that of a land-based converter station, on one hand, the offshore conversion platform is compact in equipment layout and complex in environmental working condition, the real-time and accuracy requirements on equipment state data are extremely high, and on the other hand, the three-dimensional scene model needs to consider the dynamic linkage of equipment entities, building structures and marine environments so as to adapt to the special meteorological and operation and maintenance conditions at sea. At present, although an attempt is made in the industry to construct a unified data interface for a converter station to realize basic access of data, a systematic architecture design and management method is not formed aiming at scene characteristics of an offshore converter platform, various data are stored and extracted in a stacked mode, frequency characteristic matching differential transmission protocols of the data are not combined, and an accurate binding relation between the data, equipment group components and a three-dimensional scene model is not established. When the existing offshore converter station data management method is used for constructing a three-dimensional scene model, a traditional triangulation algorithm is still adopted, the algorithm is used for carrying out global indiscriminate subdivision calculation on all point cloud data in a global range when 3D scattered data points of the whole scene of the converter station are processed, and when the offshore converter station multi-device and large-scene high-density point cloud data are faced, a great amount of calculation force is consumed for single round subdivision to complete the associated operation of millions of data points and even tens of millions of data points, so that the calculated amount is exponentially increased, and finally, the time cost of operation and maintenance personnel in the data management work is greatly increased. Disclosure of Invention The invention provides a data management method and a data management system for an offshore converter station, which solve the technical problem that the time cost of operation and maintenance personnel in data management work is greatly increased by the existing data management method for the offshore converter station. The invention provides a data management method of an offshore converter station, which comprises the following steps: acquiring high-frequency data and low-frequency data of converter station equipment and corresponding real-time meteorological data, transmitting the high-frequency data and the low-frequency data by adopting a data transmission interaction protocol, and outputting high-frequency real-time data and low-frequency application data; binding the high-frequency real-time data with the low-frequency application data and the converter station equipment, and determining converter station equipment component association data, converter station equipment association data and converter station equipment position association data; Constructing an integrated storage library according to the converter station equipment component association data, the converter station equipment positio
