Abstract
The invention relates to a novel integrated ice detector. A detection portion is mainly composed of a sensitive component and a resolving component. The resolving component provides a drive signal for the sensitive component. The sensitive component detects the thickness of an ice layer, converts the thickness into an electric signal and provides an ice component for the resolving component. Due to the integrated design, the size and weight of the detector are reduced, the adaptability of the detector for various types is improved; as for existing rapidly-developing unmanned aerial vehicles and helicopters, the integrated ice detector has the advantages of being small in size and low in weight and has the anti-electromagnetic interference capacity which a common ice detection device does not have.
