Abstract

The invention relates to an optical fiber type ice binding state sensor, and belongs to the photoelectric sensors. The problem that an existing icing sensor cannot be used for judging the ice layer and material surface binding state is solved, and the optimal shock excitation opportunity is conveniently selected for an electric heating-shock excitation composite type ice removal method. The optical fiber type ice binding state sensor comprises M transmitting optical fiber bundles and N receiving optical fiber bundles, one end of the M transmitting optical fiber bundles and one ends of the N receiving optical fiber bundles are bundled into a metal shell to form concentrated optical fiber bundles, the end face of the optical fiber bundles forms a detecting end, one light source device is installed at the other end of each of the M transmitting optical fiber bundles, and spectrums of the M light source devices are different; and one photoelectric receiving device is installed at the other end of each of the N receiving optical fiber bundles. The optical fiber type ice binding state sensor is small in size, light, capable of achieving multi-point distribution, free of movable accessories, high in reliability and simple in signal treatment, the optical fiber type ice binding state sensor can be used for analyzing influences of phase changes of an ice layer on the object surface on different spectral signals after temperature changes, and the optical fiber type ice binding state sensor is suitable for detecting the binding state of the object icing surface and the ice layer.

Description

technical field [0001] The invention belongs to a photoelectric sensor, in particular to an optical fiber ice binding state sensor, which can qualitatively judge the binding state of an ice layer on the surface of an object, and is applied to the fields of icing detection and anti-icing. Background technique [0002] At present, the electrothermal-excited vibration compound deicing method used for wing deicing firstly reduces the bonding strength between the icing ice layer in the icing area of ​​the wing and the metal skin of the wing by heating after the icing occurs, and then through The exciting vibration destroys the icy layer adhering to the surface of the wing and makes it fall off. In this process, when the vibration starts and how much excitation force is required, effective information is needed as a support. Especially for judging the timing of vibration after heating, it is necessary to detect the combination state of the icy ice layer on the wing surface and th...
