Airplane residual ice monitoring device capable of eliminating environment interference

Abstract

The invention discloses an airplane residual ice monitoring device capable of eliminating environment interference. The airplane residual ice monitoring device comprises an integrating sphere sensor, a beam splitter prism and light filter control device, an infrared light source, a control unit, a light filter control device, a near infrared surface array CCD (charge coupled device) camera, an infrared image acquisition processing unit, a computer data processing control unit and a detection result pseudo-color display unit. The airplane residual ice monitoring device capable of eliminating environment interference, which is disclosed by the invention is capable of eliminating, t the environment interference is eliminated through the integrating sphere sensor, thus realizing precision detection of on residual ices. Compared with the prior art, the airplane residual ice monitoring device has the following remarkable advantages that in a process of detecting the residual ices on an airplane body of the air plane, the integrating sphere sensor can be used for monitoring environment light, stabilizing the light source and eliminating the interference of the external environment, and therefore, the aim of precision measurement can be fulfilled.

Description

technical field [0001] The invention belongs to the technical field of civil aviation, and in particular relates to an aircraft residual ice monitoring device capable of eliminating environmental interference. Background technique [0002] The problem of aircraft deicing has become one of the important factors affecting the safe operation of civil aviation in winter. According to the statistics of the US National Transportation Safety Board (NTSB): During the seven years from 1981 to 1988, there were 542 flight accidents caused by icing in the United States, and about half of the accidents were caused by icing. In order to prevent such accidents, it is usually necessary to use deicing fluid to de-ice the surface of the aircraft and detect the residual ice on the surface before take-off. [0003] At present, the commonly used automatic detection system for residual ice mainly uses a system composed of infrared multispectral camera, infrared light source and other components ...

Problems solved by technology

However, since this kind of automatic residual ice detection system is seriously affected by environmental interference, the detection accuracy is not high, so the current airport still mainly uses artificial vision and tactile detection methods
