Embodiment Construction

[0087] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0088] Such as Figure 1-Figure 2 As shown, the video surveillance system based on wind turbine blades includes:

[0089] As a digital camera as a video acquisition unit, the digital camera is electrically connected to a controller on which a background picture acquisition module and a picture abnormality monitoring module run; the controller can be a single-chip microcomputer.

[0090] The digital camera is used to perform video acquisition on fan blades to obtain a sequence of video images;

[0091] The background picture obtaining module is used to extract the background picture from the video picture sequence obtained by the video acquisition module;

[0092] The picture abnormality monitoring module is used to monitor whether there are abnormal picture features on the leaves in the pictures in the video picture sequence by virtue of the extracted...

Abstract

The invention discloses a fan blade-based video monitoring system and method, and the system comprises a digital camera which is electrically connected with a controller, and a background image obtaining module and an image abnormality monitoring module are operated on the controller; the digital camera is used for performing video acquisition on fan blades to obtain a video picture sequence; the background iamge obtaining module is used for extracting a background iamge through the video iamge sequence obtained by the video acquisition module; the defect that in the prior art, when the controller in the monitoring equipment for the fan blade executes extraction, the electronic assembly of the controller needs to bear too large tasks in the processing period of video images and a plurality of result images is effectively overcome.

Description

technical field [0001] The invention relates to the technical field of fan blade monitoring, in particular to a fan blade-based video monitoring system and method. Background technique [0002] Wind turbines, referred to as fans for short, include wind rotors and generators; the wind rotors are composed of fan blades, hubs, and reinforcements; The wind power supply is composed of wind turbines, towers supporting wind turbines, battery charging controllers, inverters, unloaders, grid-connected controllers, battery packs, etc. Because of the importance of fan blades in the process of wind power generation, there is currently a monitoring device and method for fan blades, which includes: a digital camera, the digital camera is electrically connected to a controller, and a A background picture acquisition module and a picture abnormality monitoring module; the digital camera is used for video acquisition of fan blades to obtain a video picture sequence; the background picture a...
