The RFID airworthiness certificate anti-counterfeiting communication inspection method according to claim 8, wherein: step B21 further includes, before extracting the text C2 of the certificate to be checked: extracting an R channel of the picture to obtain a threshold value T by a maximum class interpolation method; and carrying out binarization processing on the red channel by using a threshold value T and removing the red seal in the image.
10. The RFID airworthiness certificate anti-counterfeiting communication checking method according to claim 6, characterized in that: step E also includes: the storage module (4) stores image data collected by the camera (8), interactive data on the touch screen (2), data comparison and inspection process data of the inspection processing system, and feeds back and transmits the data to the AMOS system (10) through the communication module (9).
