Abstract

The invention relates to a freezing detector and belongs to the technical field of freezing detection. The freezing detector comprises a freezing component, at least one vision sensor and a controller, the freezing component comprises a freezing rod with an ice accretion surface and a support structure, and the freezing rod is constructed into a streamlined wing structure and extends into air current from the support structure; the vision sensor is arranged to be an image which can acquire the ice accretion surface; and the controller is electrically connected with the vision sensor and comprises an image comparison module for comparing the acquired image with an initial image so as to judge whether the ice accretion surface of the freezing rod is frozen. According to the freezing detector, moving components are absent, and the reliability of image based judgment is high; and simultaneously, by means of the streamlined wing structure of the freezing rod, the ice accretion surface is provided with small pressure coefficients and large water collection coefficients, the freezing rod can faster and earlier freeze, and time for giving freezing warning can be brought forward.

Description

technical field [0001] The invention relates to the field of icing detection, in particular to an icing detection device for detecting icing conditions. Background technique [0002] When the aircraft is flying under icing conditions, icing is very easy to occur on the leading edge of the wing and the leading edge of the nacelle. Icing on the surface of the aircraft will lead to degradation of aircraft handling quality, loss of flight performance and reduction of flight safety margin. [0003] At present, most civil aircraft and transport aircraft are equipped with flight icing detection systems. The icing detection system can detect the aircraft entering icing weather conditions or icing on the surface of the aircraft at an early stage, so as to issue an icing warning message, prompting the pilot to manually activate the anti-icing system, or the icing detection system can directly activate the anti-icing system. Therefore, icing detection is an important measure to ensur...
