Detailed Description

In order that the above-recited objects, features and advantages of the present invention will be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.

as shown in fig. 1, the present invention provides a method for managing construction period of engineering construction projects based on BIM and GIS, comprising:

s102, acquiring construction file information and project surrounding GIS information, constructing a target engineering project BIM model according to the construction file information, integrating multi-source data according to the project surrounding GIS information and constructing a high-rendering three-dimensional scene;

constructing a checking standard according to the target engineering analysis information, performing consistency check on the target engineering project BIM model, marking an abnormal part to obtain check result information, and performing model optimization and modification according to the check result information;

S104, dividing the target project, binding the target project BIM model and the high rendering three-dimensional scene according to the dividing result, and associating the target project with the corresponding construction unit and the corresponding construction scene;

It should be noted that, the "unit subsection" is to divide the project of the target project, from the angle required by the project construction, because the project contains many things, steel bars, concrete, templates, hydroelectric bushings, hydroelectric lines, doors and windows, brick walls, etc., too many materials are too miscellaneous, so as to facilitate the reference and planning, the engineering materials subsection is classified, and the project is divided into: unit engineering, sub-sub engineering, sub-project, inspection lot, thereby helping project constructors to better understand the constitution of the project itself. The construction unit division is to divide the construction unit of the target project and divide the construction unit from the human resources or human organization architecture concept, thereby facilitating the detailed understanding of the construction unit of the target project.

It should be noted that, according to the construction drawing design file, a refined BIM model is constructed based on the "drawing model consistency" criterion, so as to form a "BIM model of engineering construction project", namely a "high fineness model". According to 'GIS data around engineering construction projects' such as orthophotos, oblique photography, elevation measurement files, the 'high-rendering three-dimensional scene' is formed by converting the data into a unified format, integrating multi-source heterogeneous data and based on a high-rendering graphic engine. The unit subsection items of the classification division before construction are led into the system, and form one-to-one or one-to-many binding relation with the high-fineness model and the high-rendering three-dimensional scene. Thus, the "forming system basic data" is completed.

An interactable and fictive three-dimensional space scene is simulated through the panoramic picture. With the development of technology, the periodic shooting of panoramic pictures by unmanned aerial vehicle and other means becomes an important means for periodic recording of construction progress in engineering construction projects. The panoramic picture module supports the view of panoramic pictures and gives time labels, and provides means for recording project construction processes. By pertinently reinforcing the GIS model and the GIS engine, the method has stronger applicability to engineering construction projects (such as highway engineering and channel engineering in water transportation) with large geographic space scale. Dividing a BIM model and a GIS model into a 'high-fineness model' and a 'high-rendering three-dimensional scene' aiming at an application scene, wherein the GIS model is used for displaying a macroscopic space geographic environment in a focusing manner, and the BIM model is used for displaying structural details in a focusing manner; different emphasis is given to meeting the requirements of different service scenes, and the method has good applicability.

And the progress of the construction plan is displayed in the form of three-dimensional model animation by importing the progress plans of different sub-projects. And (3) judging the progress state of the sub-project by comparing the actual progress with the planned progress, and marking the advance, normal and lag states of the sub-project. And visually and vividly displaying the progress state of the sub project by a three-dimensional graphical interface. Based on the high rendering three-dimensional scene, the data visualization with the functions of charts, texts, videos, plotting and the like is combined to carry out the intelligent reporting based on the three-dimensional scene. The overall experience is similar to "three-dimensional PPT". A set of intelligent reporting materials consists of a plurality of pages, wherein each page comprises a data visualization component and a three-dimensional scene serving as a background.
