Abstract

The invention discloses a device and method for detecting and deicing, which belong to the field of anti-icing. The ice layer or water film on the surface of the film constitutes the area to be measured; the complex impedance measurement module is connected to the complex impedance sensor for sampling and measuring the complex impedance data of the area to be measured within the preset measurement frequency band; the control module is connected to the complex impedance measurement module , used to calculate the impedance mode in the low frequency band and the relative discrete index of the equivalent capacitance of the area to be measured in the preset measurement frequency band according to the complex impedance data; judge the target according to the relationship between the impedance mode, the relative discrete index and the corresponding threshold The state of the surface of the structure, and control the deicing of the deicing unit when the state is icing. The icing condition on the surface of the structure is detected based on the complex impedance, and it is suitable for anti-icing and deicing in various occasions, especially where the air velocity is high.

Description

technical field [0001] The invention belongs to the field of anti-icing, and more particularly relates to a detection and de-icing device and method. Background technique [0002] Structural icing is almost inevitable under natural conditions, especially for equipment and facilities such as wind turbines, aircraft, EMUs, and outdoor communication equipment. Icing on the surface will lead to problems such as performance degradation, economic benefit reduction, and even safety hazards. Therefore, in order to improve the operational efficiency and safety of related equipment and facilities, the importance of anti-icing systems has gradually become prominent. [0003] Existing anti-icing systems come in various forms, and the piezoelectric ice measurement method is usually used to detect the icing situation in the anti-icing area. The piezoelectric ice measurement method is to judge whether the surface of the structure is icy by detecting the vibration frequency of the anti-ic...
