Power transmission project entity acceptance method based on Cesium platform

Abstract

The invention provides a power transmission project entity acceptance method based on a Cesium platform, and belongs to the field of power transmission and transformation project construction. According to the method, improvement of a power transmission project entity acceptance means is taken as a target, and a power transmission project GIM power grid information model is imported into a Cesium geographic information platform to serve as design standard data; a three-dimensional laser scanner is adopted to scan in a power transmission project construction site to obtain laser point cloud data, and a power transmission project laser point cloud model is established after processing is performed by taking a span as a unit; traversing the whole line of the GIM model of the power transmission project, and finding the GIM model matched with each laser point cloud model; and manually selecting points in the point cloud data to measure various to-be-accepted parameters, and comparing the to-be-accepted parameters with a standard value to obtain a construction error. The system has the advantages of high automation degree, no need of field measurement of workers and multiple types of acceptance items, reduces the workload of the acceptance workers to a certain extent, and effectively improves the quality and efficiency of the acceptance work of the power transmission project.

Description

technical field [0001] The invention belongs to the field of power transmission and transformation engineering construction, and in particular relates to a method for actual acceptance of power transmission projects based on a Cesium platform. Background technique [0002] As the scale of transmission line construction in my country increases year by year, it is bound to face a large number of completion inspection and acceptance work of transmission projects. However, in the current acceptance work, there are still many defects. For example, the acceptance of key items such as the upper part of the iron tower, the ground wire and the accessory fittings must be completed by means of climbing operations or telescopes. This method not only has safety risks, but also the data is real. In addition, the main form of work is 2D drawings, but 2D drawings are not conducive to the spatial imagination of the staff. According to the statistics of researchers, 60% of construction errors...

However, in the current acceptance work, there are still many defects. For example, the acceptance of key items such as the upper part of the iron tower, the ground wire and the accessory fittings must be completed by means of climbing operations or telescopes. This method not only has safety risks, but also the data is real. In addition, the work form is mainly based on 2D drawings, but the 2D drawings are not conducive to the spatial imagination of the staff. According to the statistics of researchers, 60% of construction errors come from the misunderstanding of the construction drawings by the staff.
