Technical Field
The invention relates to the technical field of engineering project visualization, in particular to a display system for an engineering project centralized display platform.
Background
With the increasing of national economy, city construction is rapidly advanced, and the method is particularly important for displaying and managing city engineering projects. The traditional engineering project display and management method has the characteristics of information lag, low informatization degree and the like, and restricts the development of the engineering progress management level. And the engineering projects have a lot of technologies, but most of the technologies are based on two-dimensional plane drawings, and the complex construction drawings given by the technologies are difficult to understand for general personnel, so that the understanding of a decision layer and a management layer on the engineering projects is not intuitive.
In order to solve the above problems, chinese patent publication No. CN109447479A discloses a project management system based on three-dimensional visualization, which includes a BIM three-dimensional model building module; a GIS three-dimensional topographic map building module; the real three-dimensional engineering model building module is used for combining the BIM three-dimensional model building module with the GIS three-dimensional topographic map building module to generate a real three-dimensional engineering model; the engineering management platform is used for managing the engineering project through a manager terminal; the three-dimensional engineering model display module is used for combining the construction information input module data and the engineering management platform data with the true three-dimensional engineering model building module and realizing the sharing of engineering component information; and the database server is used for storing and sending data.
The project visualization management system in the existing scheme is equivalent to a project centralized display platform, and the project is displayed in detail through a three-dimensional model, so that managers can visually acquire information of the project. However, in the existing scheme, the engineering projects are only displayed in a three-dimensional model manner, and for an enterprise with a large number of engineering projects and a wide engineering project distribution range, the three-dimensional display manner is difficult to realize global display of the engineering projects (all the engineering projects are concentrated on one engineering map, and a single engineering project is only one point), so that the effect of displaying the engineering projects is poor. In the prior art, by only displaying the engineering map (two-dimensional map), when a single or local engineering project needs to be displayed, the problems of unclear and non-intuitive detail display exist, and the problem of poor effect of displaying the engineering project is also caused.
