The technical solutions provided by the present invention will be described in detail below with reference to specific examples, and it should be understood that the following specific embodiments are only illustrative of the present invention and are not intended to limit the scope of the present invention. Additionally, the steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions and, although a logical order is illustrated in the flow charts, in some cases, the steps illustrated or described may be performed in an order different than here.
The invention is realized based on an automatic monitoring system, and the automatic monitoring system at least comprises a data acquisition module for acquiring monitoring data, a data processing module for processing and calculating the monitoring data and a display module for displaying the data. The data acquisition module is a sensor, an instrument and the like which are arranged at key positions of the unit foundation engineering, and the sensor and the instrument can monitor and acquire various data, such as deformation, inclination, vibration, corrosion, settlement, scouring and the like. The data processing module is realized by adopting a computer arranged in a monitoring place and a cloud data center. The display module is generally a display device disposed in a monitoring place and a cloud data center. The invention provides a dynamic management and visualization method for offshore wind power safety monitoring information, which is used for dynamically maintaining and managing complex and massive monitoring basic information in a remote information management mode on the basis of an automatic monitoring system, and particularly, the overall flow is shown in figure 1, and the method comprises the following steps:
the method comprises the following steps: establishing a classification system of offshore wind power safety monitoring spatial information
As shown in table 1, the present invention divides the feature space information into four levels: the basic spatial information of the sea area where the offshore wind farm is located is first-level, the spatial information of the key monitoring area is second-level, the spatial information of the automatic safety monitoring subentry system is third-level, and the spatial information of the monitoring unit is fourth-level. The first-level ground features comprise a plurality of second-level ground features, the second-level ground features comprise a plurality of third-level ground features, and the third-level ground features comprise a plurality of fourth-level ground features. The first-level ground object names comprise coastal terrain, sea areas, administrative divisions, wind power plant areas and the like, and the first-level ground object names represent large divided space areas. The names of the secondary land features include a dock, a fan, an offshore booster station, a land station and the like, the level information includes a small area, a place, a station, large equipment and the like in the sea area of the offshore wind farm, the names of the secondary land features are further classified, for example, in table 1, the fan is classified into a base, a blade, a cabin and a tower, and the offshore booster station is classified into a base and an upper block. The more the grading levels are, the more detailed the monitoring and display of the ground features are. The names of the three-level ground objects include settlement, inclination, vibration, navigation channels and the like, and the level information includes the movement, deformation, displacement graph and track of the two-level ground objects. The four-level ground object name comprises measuring points, instruments and the like, and the level information is the coordinates of each monitoring station and equipment of the three-level ground object. The data type corresponding to each feature name is illustrated in the table.
TABLE 1 marine wind power surface feature space type division table
The invention is illustrated by a specific example. Table 2 is an example of spatial classification of the offshore wind farm. Wherein, the region of the offshore wind farm 1 is a primary ground object space category, and the data type is represented by a Polygon (Polygon); the interior of the offshore wind farm 1 is divided into a wharf, a fan, an offshore booster station and a land station, and is classified into two-level ground object space types uniformly, data types expressed in a macroscopic mode are all represented by points (points), data types expressed in a primary microscopic mode are represented by plane polygons (Polygon), and data types expressed in a high-level microscopic mode are represented by a three-dimensional graph (Volume). The example ignores secondary ground feature macro expressions and advanced micro expressions. Three wind turbines are shown in table 2, with secondary ground names including base, blades, nacelle, tower, etc. Taking the wind turbine 1 as an example, the basic settlement 1 data, the tower inclination 1 data and the blade vibration 1 data in the wind turbine 1 are the space information of the automated safety monitoring subentry system classified into three-level ground object space categories, and the data types are represented by arcs (lines). Still take the fan 1 as an example, wherein the monitoring unit is classified into four-level ground object space categories, and mainly includes measured Point data (the measured Point data refers to space information such as generated according to the longitude and latitude of the measured Point, and covers which monitoring system belongs to which fan), and instrument data (indicating the instrument is at which measured Point position), and the data type is represented by Point (Point). Therefore, the step allocates four types of space type attributes of points, arcs, surfaces and bodies to all ground features on the basis of classification.
TABLE 2 offshore wind farm spatial Classification example
Step two: and recording the topological relation (the relation such as adjacency, association, inclusion and communication among various ground features represented by the points, the arcs and the surfaces) of the adjacent ground features on the basis of the three-dimensional coordinates of the points by recording various types of ground feature space information divided in the first three-dimensional coordinate recording step and forming a solid figure by the points, the arc forming surfaces and the surfaces. Single point feature space information is recorded as (longitude, latitude, elevation), as station 1 is recorded as (120.728783, 33.630795, 54.223419), station 2 is recorded as (120.728784, 33.630795, 54.223419), station 3 is recorded as (120.728785, 33.630795, 54.223419), station 4 is recorded as (120.796561, 33.630631, 62.704765);
the arc-shaped ground object is composed of an arc-segment start node, an arc-segment end node and a point three-dimensional coordinate set of an intermediate point string, and the geometric topological relation of the sequential connection order representation points of the corresponding nodes is recorded. The surface feature space information records of the "settlement 1" as the subentry monitoring system are shown in table 3:
TABLE 3 example table for recording spatial information of arc shaped ground objects
The planar ground object is formed by recording a plurality of arc sections forming the planar ground object, and the sequential connection sequence of the corresponding arc sections is recorded to represent the geometric topological relation of the arc sections. The surface feature space information records as "fan 1-based" are shown in table 4:
table 4 surface shape ground object space information recording example table
Based on table 4, all the dependent arcs of the planar terrain "fan 1-foundation" are recorded in the form of arc-shaped terrain.
The body-shaped ground object is composed of a plurality of surface records which form the body-shaped ground object, and the relative positions of the surface records corresponding to each surface represent the geometrical topological relation. Therefore, an offshore wind power safety monitoring ground object space information table is formed.
Step three: and (3) loading the ground feature space information table recorded in the step two into ArcGIS software (or other GIS software as required), and generating four types of vector layers of points, lines, surfaces and bodies, wherein if settlement 1.shp is used as a vector line layer, fan 1-base. shp is used as a vector surface layer, and fan 1 measuring point. shp is used as a vector point layer. FIG. 6 is a vector surface layer generated according to the secondary ground object wind power pile, and each measuring point is arranged in the layer.
And rasterizing the vector layer, realizing structural reorganization of marine wind power feature space information by adopting a vector-grid integrated data structure, and uniquely identifying all the feature space information of each layer level, for example, by adopting codes shown in table 5 (only part of the codes are shown in the table for example). The method has the advantages that the ground feature description has high spatial precision, the redundancy of data storage is avoided as far as possible, and meanwhile, the grid expression of the ground features facilitates the fusion of spatial information, attribute information and monitoring data.
TABLE 5 example table of ground feature code
Step four: the method comprises the steps of sequentially extracting attribute information, monitoring data and a spatial information table of a fourth-level ground object in the third step, matching the attribute information (such as data of a calculation formula, parameters, a manufacturer and the like which are stored in a database in advance) and the monitoring data (stored in the database) of a dot-shaped identifier of the fourth-level ground object, attaching unique identifiers corresponding to the spatial information of the measuring points to the attribute information table and the monitoring data table corresponding to each measuring point, cascading multiple types of data tables such as ground object basic spatial information, the attribute information, the monitoring data and the like according to the unique identifiers, endowing each association table with consistent coding fields to form a multi-table cascading relationship of offshore wind power safety monitoring points based on the unique identifiers, and establishing database storage management of the tables and the cascading relationship in LSERSQver. FIG. 5 is a multi-table cascade relationship using a measuring point ground object as an example, in which a measuring point space information table, a measuring point data information table, and a measuring point attribute information table are associated by measuring point codes for management and display.
Step five: according to the dynamic maintenance process of the offshore wind power safety monitoring measuring point shown in the figure 2, corresponding software functions are developed, and dynamic maintenance and management of the measuring point are realized by adopting a corresponding measuring point management software module. Information changes generated by any operation of the measuring point objects (the measuring points and instruments subordinate to the measuring points) in the software can trigger dynamic updating of comprehensive information associated with the measuring points in real time, and measuring point information can be maintained automatically, visually and in batch. The measuring point management software module is used for adding, deleting and modifying (editing) measuring points, adding, deleting and modifying (editing) instruments and establishing, deleting and modifying the association relationship between the measuring points and the instruments.
