Problems solved by technology

Since the icing sensor and electronic components are independent of each other, they must be connected with each other through long cables when installed on the aircraft. The small signal output by the icing sensor is susceptible to external electromagnetic interference during transmission through the cable, and the entire set The device has the disadvantages of heavy weight and large volume

Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] The integrated icing detector consists of a vibrator assembly 1, a power supply circuit board assembly 4, an execution and frequency circuit board assembly 2, and a signal processing circuit board assembly 3, as shown in the attached manual figure 1 , figure 2 .

[0018] The vibrator assembly 1 detects the thickness of the ice layer and converts it into an electrical signal, and provides a feedback signal to the execution and frequency circuit board assembly 2 .

[0019] Under the combined action of the excitation signal and the electromagnetic system on the vibrator assembly, the probe of the vibrator assembly 1 will oscillate and reach stability when certain phase and amplitude conditions are met. The vibration frequency at this time is the working frequency of the vibrator assembly. frequency. When ice is deposited on the vibrating head of the v...

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.

Description

technical field [0001] The invention belongs to the technical field of anti-icing and relates to an integrated icing detector. Background technique [0002] The icing detector is a special detection and warning device used to detect whether there is icing on the surface of the aircraft when the aircraft is flying under icing weather conditions. The old-fashioned icing detection devices use an independent icing sensor to collect icing signals, and then send the collected signals to a subsequent independent electronic component for settlement, and the obtained icing alarm signal is sent by the electronic component to the Aircraft warning system transmission. Since the icing sensor and electronic components are independent of each other, they must be connected with each other through long cables when installed on the aircraft. The small signal output by the icing sensor is susceptible to external electromagnetic interference during transmission through the cable, and the entir...
