Embodiment 1

[0053] An embodiment of the present invention provides a method for measuring the inclination of a transmission line tower. figure 1 It is a flow chart of a method for measuring the inclination of transmission line towers provided by Embodiment 1 of the present invention. Refer to figure 1 , methods include:

[0054] S110. Obtain the full tower image of the tower in the direction along the line and the full tower image in the direction transverse to the line.

[0055] Specifically, the pole tower is a general term for electric poles and iron towers. The purpose of the tower is to support the conductor and the lightning conductor, so that a certain safety distance is maintained between the conductors, between the conductor and the lightning conductor, between the conductor and the ground and crossing objects. Affected by the tension of the wires, the towers with high-voltage wires will tilt along the direction of the wires and move in position. The displacement of the pole t...

Abstract

The embodiment of the invention discloses a method, device and system for measuring the inclination of a power transmission line tower. The method comprises the steps of obtaining a whole tower imageof the tower in the line direction and a whole tower image of the tower in the transverse line direction; determining an along-line direction reference point according to the whole-tower image in thealong-line direction, and determining a transverse-line direction reference point according to the whole-tower image in the transverse-line direction; obtaining a first inclination amount according tothe along-line direction reference point, and obtaining a second inclination amount according to the transverse-line direction reference point; and calculating the inclination of the tower accordingto the first inclination amount and the second inclination amount. According to the technical scheme provided by the embodiment of the invention, the inclination of the tower is automatically detectedthrough the computing terminal, and the quickness and high efficiency of tower inclination detection are improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of measuring the inclination of transmission line towers, and in particular, to a method, device and system for measuring the inclination of transmission line towers. Background technique [0002] The transmission line is composed of line towers, wires, insulators, line fittings, guy wires, tower foundations and grounding devices, etc., and is erected on the ground. [0003] Among them, the inclination measurement of transmission line towers is mainly carried out by erecting theodolite on the ground, which takes a long time and is inefficient. At the same time, due to the limitation of terrain conditions and the occlusion of plants around the tower, the theodolite cannot measure the measuring ruler placed on the tower leg, resulting in the inability to The measurement or measurement results are highly biased.
