Problems solved by technology

However, they also have certain defects: the magnetostrictive vibrating cylinder ice detector has complex structure, high production process requirements, difficult calibration, and cannot be installed flush and conformal on curved surfaces (such as the leading edge of aircraft wing tail); Although the electro-diaphragm ice detector is small in size and weight, it can achieve flush and conformal installation on curved surfaces to a certain extent, but the production requirements for its sensitive materials are stricter, the process

Embodiment Construction

[0036] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] The image icing detector according to the first preferred embodiment of the present invention mainly includes an image acquisition system and an image processing system, the former is used to acquire images from the surface of an object, and then the latter calculates and analyzes the acquired surface images, so that the final Obtain the icing condition on the surface of the object.

[0038] First refer to figure 1 , which shows the image acquisition system 1-A of the image icing detector according to the above-mentioned first preferred embodiment.

[0039] Among them, the core component of the image acquisition system 1-A is the image transmission fiber optic bundle 104, which can receive the surface image of the object at the front end, and transmit the surface image to other components connected to the rear end along the optical fibe...

Abstract

The invention relates to an image icing detector, which comprises an image acquisition system (1-A) and an image processing system (2-A). The image acquisition system (1-A) is used for obtaining an image of the surface of an object, and the image processing system (2-A) is used for analyzing the image to obtain information on icing of the surface of the object. The detector has a simple structureand high reliability, icing types can be effectively identified, the icing detection accuracy can be significantly improved, detection of the surface of the whole object can be realized, and information on icing of large supercooled water drops can also be detected.

Description

technical field [0001] The invention relates to an image icing detection device, which is used to obtain information on icing conditions on the surface of an object by analyzing images of the surface of the object, including whether it is icing, the type of icing, the thickness and / or area of ​​icing, and the like. Background technique [0002] In many cases, it is necessary to detect and analyze the icing condition of a specific surface or part of an object. For example, in cold regions, it is necessary to monitor the icing condition of the road surface in winter, to detect the icing condition of the blades of the wind turbine and some rotating parts, and to monitor the multiple parts of the body (such as the windshield) during the flight of the aircraft. , wing tail leading edge, engine intake, etc.) to monitor the icing phenomenon to avoid adverse effects of icing on flight and prevent serious flight safety accidents caused by icing. It should be noted that the word "ice...
