Method and device of establishment of three-dimensional monitoring model of urban underground pipelines, storage medium and terminal equipment

Abstract

The embodiment of the invention discloses a method and a device of establishment of a three-dimensional monitoring model of urban underground pipelines, a storage medium and terminal equipment. The method includes: acquiring pipeline completion measurement data of an urban underground pipeline system of which a model is to be constructed; constructing a three-dimensional model of each basic component according to space location information and attribute features of each basic component; generating a three-dimensional stereoscopic model of the urban underground pipeline system in a coupling manner according to space connections among all the basic components; and associating real-time pipeline running state information acquired by each sensor loaded in the urban underground pipeline systemwith a corresponding location of the sensor in the three-dimensional stereoscopic model to obtain the three-dimensional monitoring model of the urban underground pipeline system. By implementing the method, the sensors are associated with the locations thereof in the three-dimensional stereoscopic model, and the formed three-dimensional monitoring model facilitates real-time acquisition of the real-time running status information of the urban underground pipelines.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method, device, storage medium and terminal equipment for establishing a three-dimensional monitoring model of urban underground pipelines. Background technique [0002] Completion measurement is an important means of urban underground pipeline data collection, database building, and dynamic update. Article 8 of the "Urban Underground Pipeline Project File Management Measures" clearly stipulates that before the underground pipeline project is covered with soil, the construction unit should entrust an engineering surveying unit with corresponding qualifications. According to the "Urban Underground Pipeline Detection Technical Regulations" (CJJ61), the as-built survey is carried out to form accurate as-built survey data files and pipeline engineering survey drawings. [0003] On the one hand, the spatial position information of the pipeline (such as the X / Y coordinates of the s...

Problems solved by technology

[0005] First of all, at present, most urban completion measurement data are still expressed in two-dimensional pipeline graphic data: with the rapid development of urban construction, the spatial distribution of underground pipelines is becoming more and more complex, and the traditional two-dimensional underground pipeline graphic results are difficult to express the relationship between pipelines. The complex spatial hierarchical relationship, especially for the vertically distributed pipelines in the underground space, can only be represented by a point or overlapping line or intersecting line and corresponding annotations on the plan. The pipeline data in reality is buried in the real three-dimensional In the geographical environment, compared with the 3D pipeline scene map, the 2D pipeline map often has the following shortcomings: it cannot intuitively express the spatial position relationship between underground pipelines and pipelines, such as some pipeline intersections, collisions, crossings, etc. in the 3D pipeline diagram , cannot be seen in the two-dimensional pipeline diagram; cannot intuitively express the spatial position relationship between the underground pipeline and other buildings (structures) on the ground; cannot visually display the cross-sectional shape of the pipeline and (such as square pipe or round pipe, etc.) Dimensional relationship; the connection relationship between pipelines and their accessories (such as well chambers and valves, etc.) cannot be expressed intuitively, etc.

[0006] Secondly, the completion survey of underground pipelines cannot obtain real-time status information of future pipeline operation: each city carries out underground pipeline surveys or completion surveys, although the spatial location and basic attribute information (such as ownership, category, material, management, etc.) of underground pipelines can be obtained. diameter, burial age, etc.), but it is impossible to obtain real-time status information such as pressure, concentration, and temperature during the operation of the pipeline. Since the health status of these pipelines is not obtained in real time, corresponding safety protection or operation and maintenance cannot be taken in time Some underground pipelines have been overdue and overloaded, resulting in cross-flow of urban sewage, leakage of tap water, explosions of gas pipelines, etc.
