The invention belongs to the field of airplane structure detection systems, and relates to a form-preserving icing detection system which comprises an anti-icing base body, an embedded temperature sensor and a control system, the embedded temperature sensor can sense the external temperature of an airplane, and the anti-icing base body can heat the external environment of the embedded temperature sensor until the external environment meets the heating control rule condition; standard state information exists at the position, corresponding to each temperature interval, in the heating control rule of the airplane, and after the embedded temperature sensor is located in the control interval of the heating control rule, whether the airplane encounters the icing weather or not can be accurately judged through the icing detection module in combination with the existing heating control rule; the embedded temperature sensor is arranged on the outer surface of the airplane and does not protrude out of the outer surface of the airplane, so that the appearance of the airplane does not change, the embedded temperature sensor is arranged to be in smooth transition with the outer surface of the airplane to ensure that the external performance of the airplane does not change, measurement is accurate, and the structure is simple and stable.
Description
Technical field [0001] The present application belongs to the field of aircraft structure detection systems, and relates in particular to a form of ice detection system and method. Background [0002] The icing detectors currently installed on transport aircraft are usually resonant icing detectors. Such detector probes usually maintain a certain frequency range before icing, and when the probe freezes, the ice buildup changes the quality of the probe, which in turn causes the probe frequency to change. The control module inside the icing detector detects that when the probe frequency falls below a given frequency range, it issues an icing alarm message. Therefore, such icing detector probes must be exposed to the surface of the body, so that the probe can collect cold water droplets and freeze. [0003] The exposure of the icing detector will affect the shape of the body and the external performance of the fuselage, so how to design a system that fits the surface of the body an...
