The invention discloses an airplane ground icing active detection method and device, a terminal and a storage medium, and relates to the technical field of civil aviation ground guarantee detection. The detection device is embedded into the surface of the simulation wing, the first wing skin and the surrounding second wing skin are at the same height, the second wing skin is a one-third wing part, the operation environment is a parking apron, and the detection is installed at the height of an airplane through a support. The lower port of the shell is fixed at the edge of the bottom sealing plate, and the two are of open net structures; a finned radiator is arranged in the shell, and the bottom of the finned radiator is connected with a fan. The wireless communication module is used for communication, wiring is solved, cost is saved, civil aviation workers can conveniently use the system, early warning information is timely and effectively provided, and resources such as deicing equipment are reasonably allocated according to the early warning information. The active cooling and icing early warning function is achieved through driving and temperature control of the device, the flight safety and the punctuality rate are ensured, and the device is particularly important for research of the field of airport icing.
