Embodiment Construction

[0032] Below in conjunction with accompanying drawing and embodiment the present invention is described in detail:

[0033] Such as Figure 1 to Figure 2 As shown, the light curtain sensor-based transmission line galloping trajectory calibration system and calibration method of the present invention include a light curtain sensor system, a signal conditioning conversion system, a data acquisition conversion system, and a monitoring and analysis system;

[0034] The light curtain sensor system includes a transverse light curtain sensor subsystem and a longitudinal light curtain sensor subsystem. The receiving end of the light curtain sensor is respectively fixed on the upper and lower sides of the dancing range of the transmission line through the fixing device. The longitudinal light curtain sensor subsystem is composed of multiple sets of longitudinal light curtain sensors. The transmitting ends of multiple sets of longitudinal light curtain sensors and the receiving ends of...

Abstract

The invention discloses a power transmission line waving track calibration system based on a light curtain sensor and a calibration method. The power transmission line waving track calibration system comprises a light curtain sensor system, a signal conditioning conversion system, a data collecting conversion system and a monitoring analysis system, wherein the emitting ends and the receiving ends of multiple groups of transverse light curtain sensors are respectively and fixedly arranged at the upper side and the lower side of the power transmission line waving range; the setting ends and the receiving ends of the multiple groups of longitudinal light curtain sensors are respectively and fixedly arranged at the left side and the right side of the power transmission line waving range; the monitoring analysis system screens out all high-level signals, and simultaneously records corresponding time of each high-level signal; the power transmission line waving track is finally drawn through inquiring the positions of the light curtain sensors corresponding to each high-level signal. The calibration system and the calibration method have the advantages that the high-sensitivity calibration on the waving track of a power transmission line driven by an indoor waving machine can be realized, the measurement precision is high, the measurement errors are small, and the continuity and the completeness of the power transmission line waving track calibration are guaranteed.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation equipment detection, in particular to a light curtain sensor-based calibration system and calibration method for galloping trajectory of transmission lines. Background technique [0002] Galloping of transmission lines refers to the vibration phenomenon of low frequency (0.1Hz-5Hz) and large amplitude (up to 10m or more) of transmission lines under the action of external unbalanced stress. When the outdoor transmission line dances, it often causes accidents such as damage to the fittings on the transmission tower and flashover between phases of the transmission line. In severe cases, the galloping of the transmission line will cause large-scale accidents such as the collapse of the transmission tower. Therefore, monitoring the galloping of transmission lines has important practical value and economic significance. [0003] At present, the monitoring of transmission l...
