Embodiment Construction

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not limit the present invention.

[0040] The patent technical scheme of the present invention is as follows:

[0041] The first step is to collect the GIS data of the on-site project implementation scene, mainly including elevation and landform type (mountains, rivers, hills, etc.);

[0042] In the second step, the scene is modeled according to the following grid model, and the grid model of the scene is calculated:

[0043] First, according to the accuracy of the project, select the minimum grid unit size of the scene grid model. In order to reduce the calculation difficulty and calculation time, the scheme uses a square to define the grid unit, and the unit area is:

[0044]

[0045] where W i It is the side length of a square cell. When selecting the cell ...

Abstract

The invention provides a method for quickly generating a BIM engineering project planning route. The method is characterized by comprising the following steps: collecting GIS data of a field engineering implementation scene; performing scene modeling on the scene according to the grid model, and calculating a grid model of the scene; manually dividing and segmenting an unreachable area; calculating the cost value between the adjacent grids in the grid model according to a cost value algorithm; confirming a G\ H calculation mode, and finding an optimal path according to an A * algorithm; re-calculating the planned route according to different projects and scene influence factors; dynamically calculating overall cost of the rout by adjusting the unit cost of each type of project. Accordingto the invention, the planned route is rapidly generated by combining GIS data, and the cost budget of the planned route is accurately controlled. The problems of high cost, long time consumption, high professional dependency and the like of an early-stage design planning route in an engineering project are solved, and cost budget reference is provided.

Description

technical field [0001] The invention relates to the technical field of road and bridge engineering, in particular to a method for quickly generating a BIM engineering project planning route based on GIS and A* algorithm. Background technique [0002] In the initial stage of road and bridge engineering project design, designers need to enter the project construction environment, conduct detailed on-site surveys, determine the specific distribution of rivers, mountains, towns and other detailed information in the environment, and then carry out the project according to geographical conditions, cost budget and other factors. The route design of the engineering project, and then compare the contract budget, adjust the route, and after repeated revisions, finally give the project route design plan that meets the requirements. [0003] In the process, there are many problems. Problem 1: In on-site exploration, the conditions of on-site investigation are often very harsh, which ha...
