Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0024] During specific implementation, the process provided by the method of the embodiment of the present invention can use computer software technology to realize automatic operation. see figure 1 , the embodiment includes the following steps:

[0025] Step 1, read the original tower node data. During specific implementation, the designed tower node data can be stored in a file in advance, and read from the file when the model is generated.

[0026] For the convenience of implementation, the tower node data can be stored in format. The embodiment defines the data format of the tower node as follows: node data number, x coordinate, y coordinate, z coordinate. The node in the tower node data refers to the place where two tower materials are connected and fixed.

Abstract

The invention provides a method and system for establishing a three-dimensional dynamic model of a power transmission line tower subjected to external force deformation. The method comprises the steps of reading original tower joint data, assuming that two joints of the tower are connected through a framework, constructing a framework of the tower according to the tower joint data, transforming the abstract frameworks into tower materials with solid shapes to obtain corresponding three-dimensional model data, calculating new coordinates of a new stress joint of a current time sequence point under deflection through a universal mechanical model according to external force to obtain new tower joint data, continuing to draw a new framework corresponding to a next time sequence point and obtain new tower three-dimensional model data till the tower three-dimensional model data corresponding to all the time sequence points are obtained, loading the tower three-dimensional model data to a universal three-dimensional geographic information platform, and playing the animation of the stress conditions of the tower according to the time sequence.

Description

technical field [0001] The invention relates to the technical field of electric power monitoring, in particular to a method and system for establishing a three-dimensional dynamic model of a power transmission line tower deformed by an external force. Background technique [0002] Transmission lines are an important part of lifeline projects, and their importance in ensuring the smooth operation of the national economy is self-evident. In recent years, natural disasters have occurred frequently, and tower collapse accidents on transmission lines have occurred frequently. In 2008, due to continuous low temperature and rain and snow in the south, large-scale ice disasters were caused. In the 5.12 Wenchuan earthquake in 2008, transmission lines in Sichuan Province were seriously damaged. The severe damage of transmission lines caused by wind disasters has never stopped, and the damage of transmission line tower structures caused by disaster loads in special environments has att...
