Problems solved by technology
At present, icing sensing technology has been successfully applied in many fields, but most of the icing detection technology is to detect the thickness of icing, and it is not yet mature in the calculation of icing rate. There is a certain delay in detecting icing thickness, and it cannot be realized in real time. Reflects the icing condition, and when the icing rate is too fast, the detection based on the icing thickness has certain limitations

The invention discloses an icing detector and method capable of calculating the icing rate. The detector includes a signal processing circuit, two heating components respectively placed on the windward side and the leeward side, and respectively detecting the windward side and the leeward side. Two temperature sensors for external temperature, wherein the two temperature sensors detect the real-time temperatures of the windward side and the leeward side, and the signal processing circuit controls the off / on state of the two heater assemblies according to the detected real-time temperatures; when the two When one heater assembly is in the on state, the signal processing circuit controls the two heater assemblies to maintain the same first predetermined temperature, and calculates the freezing rate according to the current difference of the two heater assemblies. The icing sensor and method of the invention can not only detect the icing thickness, but also calculate the icing rate, so that the detection of icing conditions is more comprehensive and effective.
Description
technical field [0001] The invention belongs to the technical field of anti-icing and relates to an icing sensor and a method capable of solving icing rate. Background technique [0002] The icing sensor is a special detection device used to detect whether there is ice on the surface of the aircraft when the aircraft is flying under icing weather conditions. At present, icing sensing technology has been successfully applied in many fields, but most of the icing detection technology is to detect the thickness of icing, and it is not yet mature in the calculation of icing rate. There is a certain delay in detecting the thickness of icing, and it cannot be real-time It reflects the icing condition, and when the icing rate is too fast, the detection based on the icing thickness has certain limitations. Contents of the invention [0003] In view of the above-mentioned situation in the prior art, the object of the present invention is to provide an icing sensor and method capab...
