The embodiment of the invention provides a method for constructing a multifunctional bridge control element based on a GIS system, and referring to FIG. 2, FIG. 2 is a flow diagram of a first embodiment of the method for constructing the multifunctional bridge control element based on the GIS system.
In this embodiment, the method for constructing the multifunctional bridge control element based on the GIS system includes the following steps:
step S10: and selecting a target GIS system when the bridge design is carried out.
The implementation subject of the embodiment is a GIS system for constructing the bridge multifunctional control element, and may be other devices or systems for constructing the bridge multifunctional control element, which is not limited in this embodiment, and the GIS system constructed by the bridge multifunctional control element is described as an example.
In a specific implementation, when a bridge design is required, a target GIS system may be selected, where the target GIS system may be an ArcGIS system or Skline software, or may be other systems or software with basic interaction functions of drawing points, lines, planes, and the like, which is not limited in this embodiment. Basic interaction functions such as drawing points, lines, planes and the like are provided through the target GIS system, so that the control elements can be constructed or rendered by using the target GIS system.
Step S20: and acquiring an initial bridge design scheme and an original vector database of the target GIS system.
It should be understood that the initial bridge design scheme can be designed according to the requirements of users, and the bridge design system based on the bim technology is realized in the GIS system by developing the bridge design system, so that the three-dimensional generation and rendering of the bridge design scheme are realized, and the initial bridge design scheme is obtained. The original vector database of the target GIS system refers to a database formed by vector data stored in the target GIS system, but is affected by data acquisition precision or adopts historical data, and the vector data in the original vector database is incomplete.
As shown in fig. 3, fig. 3 is a schematic diagram of an initial bridge design scheme generated in this embodiment, where the initial bridge design scheme is generated by combining a GIS system and a bim technology.
Step S30: and determining target control element data according to the initial bridge design scheme and the original vector database.
In a specific implementation, the data in the bridge solution area can be obtained through the initial bridge design scheme, and the data in the bridge solution area is compared with the vector data in the original vector database, so that the target control element data can be obtained. The target control element data refers to vector data that is missing from the original vector database.
Further, the step of determining target control element data according to the initial bridge design scheme and the original vector database specifically includes: determining structural information corresponding to the topographic image according to the initial bridge design scheme; searching the structure information in the original vector database to determine vector data lacking in the original vector database; the missing vector data is taken as target control element data.
The topographic image refers to a topographic image corresponding to a bridge solution area in the initial bridge design solution, and the corresponding structural information can be obtained according to the topographic image, and the structural information refers to control element structure information in the initial bridge design solution. The original vector database comprises collected vector data, the collected vector data can be searched in the original vector database according to the obtained structure information, whether the data in the structure information are in the original vector database is judged, when the data in the structure information cannot be searched in the original vector database, the vector data in the structure information are determined to be absent in the original vector database, and the absent vector data are used as target control element data.
The target control element data refers to the control element data of ground structures such as rivers, roads, railways, pipelines, houses and the like, which are under-bridge structures to be spanned by the bridge structures when bridge design is performed.
For river type control elements, including non-navigable rivers and navigable rivers, the non-navigable rivers are classified into a first-stage channel, a second-stage channel and the like, according to different classifications, different limit heights and limit widths are corresponding, specific parameters can be queried according to related technical standard files, and the technical standard files can be "inland navigable standard" and "sea and river navigable standard" and the like.
For the control elements of the road types, the grades are mainly divided into expressways, provincial roads, national roads, rural roads and the like, and different limit heights and limit widths are corresponding according to different classifications and specific conditions. Whether the road is planned or not can be distinguished according to the road, and only the corresponding column attribute needs to be added.
For the control elements of railway types, the grades are mainly divided into high-speed railways, inter-city railways, passenger-cargo common railways, heavy-load railways, special lines, city railways and the like, and according to different classifications, different limit heights and limit widths are corresponding, and specific parameters can be consulted by consulting technical standard files such as high-speed railway design specifications and the like.
For control elements of a pipeline type, the pipeline type is a generic term for a pipe type and a line type. The grades of the pipelines are mainly classified according to the pressure grades of liquid or gas in the pipelines, the pipelines can be classified according to a self-defined classification mode, the types of the pipelines are mainly electric wires, and specific grades can be classified according to voltage.
Step S40: and abstracting the target control element data through the target GIS system to obtain target control element abstract data.
It should be noted that, the functional module constructed by the control element is developed in the target GIS system, and the abstract processing can be performed on the target control element data by the functional module constructed by the control element, so as to obtain the abstract control element, that is, the abstract data of the target control element.
Specifically, the step of abstracting the target control element data through the target GIS system to obtain target control element abstract data specifically includes: abstracting the target control element data through the target GIS system to obtain a control element name, a control element type, a control element level, a control element mileage, a control element crossing angle, an influence line width, a control element positive width, a starting point mileage, an end point mileage, a limit width, a limit height and a ground elevation; the control element name, the control element type, the control element level, the control element mileage, the control element intersection angle, the influence line width, the control element positive width, the starting mileage, the ending mileage, the limit width, the limit height and the ground elevation are taken as target control element abstract data.
The target control element data may be abstracted by using a function module constructed by the control element, so that a control element name, a control element type, a control element level, a control element mileage, a control element crossing angle, an influence line width, a control element positive width, a starting point mileage, an end point mileage, a limit width, a limit height, a ground elevation, and the like may be abstracted, and the control element name, the control element type, the control element level, the control element mileage, the control element crossing angle, the influence line width, the control element positive width, the starting point mileage, the end point mileage, the limit width, the limit height, and the ground elevation may be used as the target control element abstract data.
In specific implementation, the mileage of the control element is the central axis of the control element abstracted by the ground structure, the included angle between the central axis and the line is the included angle of the control element, the central axis of the control element is the datum line for positioning the control element, the mileage position and the crossing angle of the control element on the line are determined, the central axis of the control element can be set with a certain width, and different representative patterns are selected according to different control element types, so that different effects can be rendered for type discrimination through texture mapping, arrow symbols can be attached in the texture mapping, and direction information such as the water flow direction of a river, the vehicle flow direction of a road and the supply direction of the pipeline can be expressed.
The influence line width is calculated mainly through the geometric triangular relation between the positive width of the control element and the crossing angle of the control element, and the starting mileage and the end mileage are calculated through the influence line width of +/-0.5 times of the control element.
Step S50: rendering the abstract data of the target control element through the target GIS system to obtain a target control element instance, and completing construction of the control element.
After the target control element abstract data is obtained, the target GIS system can be used for rendering the target control element abstract data, and the target control element abstract data is intuitively rendered, so that a target control element instance is obtained, and the target control element instance refers to the rendered target control element.
Further, after the target control element instance is obtained, the obtained target control element instance information can be stored, so that the subsequent data query is facilitated, and after the control element is constructed, the method further comprises the steps of: storing the target control element examples to generate a control element structure table; and modifying the initial bridge design scheme through the control element structure table to obtain a target bridge design scheme.
In a specific implementation, after the target control element instance is obtained, a structured table corresponding to the control element may be generated, and the structured table may be stored, and may be transferred to a relational database, for example mysql, to be stored, and in order to distinguish the control element instance data generated by current supplement from the data in the original vector database, the method further includes, after the control element structure table is generated: independently storing the control element structure table; performing authority auditing on the control element structure table to determine whether the data in the control element structure table has errors; and when the data in the control element structure table has no error, storing the control element structure table into the original vector database for management.
It should be understood that the generated control element structure table may be an independently established table, the control element structure table may be temporarily stored alone, and since it is uncertain whether the generated control element instance data is accurate, authority checking may be performed on the control element structure table, whether there is an error in the data in the control element structure table is determined, and when there is no error in the data in the control element structure table, the control element structure table is stored in the original vector database to perform unified scheduling management or the control element structure table is permanently stored. If the data in the control element structure table has errors, the data with errors can be collected again, and the data are abstracted and rendered again, so that the control element structure table is generated until the data have no errors.
In specific implementation, after the control element structure table is generated, the initial bridge design scheme can be supplemented and modified through the control element structure table, rendering display or non-display is automatically selected according to the display size of each element in the bridge scheme, the unified management capability of the GIS system on the original vector database is utilized, the control element records in the original vector database are called, and all control element examples are automatically avoided by utilizing the design function of the system, particularly the hole crossing arrangement function, so that the final bridge design scheme, namely the target bridge design scheme is obtained.
Fig. 4 is a schematic diagram of an example rendering effect of an initial bridge design control element in the embodiment, fig. 5 is a schematic diagram of an example rendering effect of a target bridge design control element in the embodiment, as shown in fig. 5. The control elements are constructed, so that the initial bridge design scheme can be supplemented and modified, the accuracy of the bridge scheme is improved, the quality of the bridge design is ensured, and the period of the bridge design is shortened.
As shown in table 1, table 1 is a control element structure table, and records in each row of the control element structure table correspond to examples of each control element, and the control elements mainly include a highway, and the like, and obtain corresponding parameters by querying corresponding technical standard files.
