Problems solved by technology

[0004] In view of the fact that the existing supervisor is more or less disturbed by factors such as the construction party, which causes human error and in the process of estimating the length of the conductor, it is usually multiplied by an empirical coefficient. The empirical coefficient is related to the terrain environment, but the current actual operation of the transmission line Lack of topographic and geomorphic information, which is mainly determined by the subjective evaluation of experts. The present invention provides a method for estimating the length of a transmission line construction conductor, including:

Embodiment 1

[0052] At present, point-to-point distance measurement on the map based on satellite remote sensing is quite mature. However, for the estimation of the length of transmission tower conductors, the existing research needs to further consider the following three issues:

[0053] (1) The altitudes of different transmission towers are different, and the estimation of the length of the wires cannot only stay on the two-dimensional plane, and the three-dimensional scene of longitude, latitude and altitude should be considered.

[0054] (2) There is sag in the conductor of the transmission line, which is not the straight line distance between two adjacent transmission towers.

[0055](3) How to provide appropriate auxiliary information for experts to determine the empirical coefficient. The experience coefficient is mainly related to terrain.

[0056] In view of this, the purpose of the present invention is to use satellite remote sensing technology to solve the above three problem...

Abstract

The invention provides a method for estimating the length of a construction wire of a power transmission line. The method comprises the following steps: acquiring the position and height of each towerof the power transmission line by utilizing a high-resolution optical satellite remote sensing image; calculating the length of a wire between adjacent towers based on the position and height of eachtower and considering the sag; and calculating the length of the wire actually required for constructing the power transmission line based on the length of the wire between all the adjacent towers. An objective and visual estimation result is provided for a power transmission line engineering investor and an audit department, possible deviation caused by manual field supervision estimation is avoided, the overall estimation efficiency of the power transmission line is improved, and the result is more objective and visual; the method is favorable for improving the fine management level of power transmission line engineering, explores a new technical means for digital auditing, and improves the intelligent level of digital auditing.

Description

technical field [0001] The invention belongs to the technical field of transmission line theory, and relates to a method and system for estimating the length of a transmission line construction wire. Background technique [0002] With the advancement of the "new infrastructure" strategy, the construction scale of transmission line projects represented by UHV continues to expand. During the construction of transmission line projects, project supervisors, investors and auditing departments must account for the wire consumables in the construction process. [0003] At present, the estimation of the wire length is often reported by the project supervisor to the project investor and audit agency, and the acceptance is completed by comparing the data with the information provided by the designer, and digital information tools are rarely used. During the process, two problems were involved: (1) The supervisor was more or less disturbed by factors such as the construction party, re...
