Embodiment Construction

[0034] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The description of the exemplary embodiments is for the purpose of illustration only, and in no way limits the invention and its application or usage.

[0035] At present, power inspection mainly includes manual inspection or manned airborne inspection. Among them, the efficiency of manual inspection is low, and the cost of manned airborne inspection is relatively high. The use of drone inspections can effectively save costs while improving efficiency. However, there is no ultraviolet imaging corona detection device suitable for small UAVs in the prior art.

[0036] Aiming at the needs of the prior art, the present invention provides a corona detection method and system for ultraviolet imaging carried by unmanned aerial vehicles. The light video signal and the visible light video signal are respectively collected; then the collected ultraviole...

Abstract

The invention discloses a UV imaging corona detection system and method for a UAV. The system comprises a corona detection device, a ground device and a shot computer; the corona detection device comprises a UV light imaging unit, a visible light imaging unit, a power supply and control board and an image memory board; and UV light video signals obtained by the UV light imaging unit and visible light video signals obtained by the visible light imaging unit are input to the power supply and control board. The power supply and control board divides the collected UV light video signals into two paths, and also divides the collected visible light video signals into two paths. One path of UV light video signals and one path of the visible light video signals are input to the image memory board to generate split-screen video signals; and the other path of UV light video signals is input to an external synchronization interface of a visible light camera, and the other path of visible light video signals and the split-screen video signals are output to the ground device in the gated manner. The system can be used for tour inspection of the UAV. The method can realize all beneficial effects of the system.

Description

technical field [0001] The invention relates to the field of corona detection, in particular to a corona detection system and method for ultraviolet imaging carried by drones. Background technique [0002] When electrical discharge occurs in high-voltage equipment in the power system, corona, flashover or arc will occur depending on the strength of the electric field. During a corona discharge, electrons in the air are constantly gaining and releasing energy. When the electrons release energy, they radiate ultraviolet light outward. Therefore, corona discharge can be detected by ultraviolet imaging technology. In power inspections, ultraviolet imaging corona detection usually uses dual-band imaging, that is, ultraviolet light imaging is performed through a sun-blind ultraviolet imaging system, and visible light imaging is performed through a visible light imaging system, so that clear ultraviolet light images can be obtained under sunlight. Thus, it forms an effective com...
