The invention discloses combined deicing system and method based on detection of ice layer-skin surface bonding state. The combined deicing system and method based on detection of ice layer-skin surface bonding state are used for removing ice accumulated on the surfaces of aircraft wings. The combined deicing system bonding state sensors arranged on inner skin of wings, heating units, an icing sensor and excitation modules and correspondingly comprises, a heating control unit, a signal conditioning unit, an excitation control unit and the like. According to signals from the bonding state sensors and temperature sensors, the information of the ice layer-skin surface bonding state can be obtained, and the appropriate deicing time can be mastered according. By adopting the method combining heating and excitation, a safe and efficient deicing with low energy consumption is achieved. Compared with a pure electric-heating deicing method, energy consumption is low, and the exciting force for exciting deicing is smaller than the exciting force of pure exciting deicing, therefore, damage to wing skin materials is small, and the effect on the aircraft aerodynamic shape is smaller.
