Embodiment Construction

[0024] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0025] See Figure 1-Figure 4 , is a schematic diagram of the measurement process of the present invention, a method for measuring the deflection of a power transmission line of the present invention, comprising the steps of:

[0026] 1) Select a station point 13 and an orientation point 14 for observing the deflection of the transmission line 12 on the spot;

[0027] 2) a laser total station is set at the station 13, positioned with the orientation point 14, and uses the laser measurement mode to measure several spatial point coordinates on the transmission line 12, and measure the spatial point coordinates of the line hanging points at the two ends of the transmission line 12;

[0028] 3) On the AutoCAD platform, draw the coordinates of the three-dimensional space points measured by the laser total station into a graph; use the LINE command to ...

Abstract

The invention relates to a method for measuring the deflection of a transmission line, comprising: 1) selecting a station and an orientation point; 2) measuring the coordinates of several spatial points on the transmission line, and the coordinates of the spatial points of the two ends of the line; 3) in AutoCAD On the platform, the spatial point coordinates are drawn into a graph; connect the two ends of the drawn graph, and rotate the drawn line segment into a horizontal line segment; 4) Set the rotated view as the current view, and use the PLINE command to connect each measurement in sequence 5) Turn back to the world coordinate system to find the lowest point of the transmission line; 6) Measure the vertical distance between the lowest point of the transmission line and the lowest hanging point, which is the vertical distance of the transmission line deflection. Compared with the prior art, the beneficial effect of the present invention is: use the laser total station to measure the coordinates of multiple spatial points on the transmission line, draw them on the CAD platform, and analyze the deflection and the lowest point of the transmission line Elevation, accurate calculation results, can provide reliable data for transmission line operation and maintenance.

Description

technical field [0001] The invention relates to the technical field of engineering measurement, in particular to a method for measuring the deflection of a transmission line. Background technique [0002] In the safe operation of power production and in the planning and design of social and economic construction, in order to ensure the safety of power production and people's lives and property, the state has clearly stipulated the safety distance, clearance distance and deflection of various transmission lines. , will pose a threat to social property and people's life and health. Surveying and mapping units often accept the entrustment of some users to measure the deflection and headroom of the transmission line, where the deflection of the transmission line refers to the elevation between the lowest point of the transmission line and the lowest hanging point. [0003] At present, the method commonly used to measure the deflection of transmission lines is to use a laser tot...
