The 3-axis gimbal UV camera. integrated with visible light cameras and ultraviolet UV sensors. The real-time synchronous fusion of the two images is used to realize the positioning of the ultraviolet sensor position, which can be detected around the clock. Among them, the video display can display ultraviolet video, visible light video, or fusion video separately, and can count the ultraviolet light points in the selected range and provide measurement data.
Drone UAV UV gimbal cameras are mainly used for ultraviolet corona discharge detection of power lines, highly sensitive detection and identification of arc, corona, and other leakage phenomena, forest fire fighting, and railway power.
The drone with UV camera sensor can be used in the early stage of power line insulation materials, although the infrared thermal imaging sensor can also detect the deterioration, it is already in the late stage of the deterioration when it is discovered. Detects corona, arc, and partial discharge phenomena of high-voltage equipment during rapid movement, so as to assess the insulation status of the power line and find the defects of the insulation equipment in time; and has strong anti-interference ability, completely free from the influence of sunlight and the limitation of detection time, which can greatly improve the efficiency of power inspection operations.
Forest fire fighting industry the drone UV sensors can detect fire sources within 2 kilometers, a long detection range, the recognition distance of the thermal camera only a few hundred meters.
The day-blind UV drone sensor features high stability, small size, lightweight, and low power consumption.
