Work-piece crack detection method based on an RFID (Radio Frequency Identification Device)

The invention discloses a work-piece crack detection method based on an RFID (Radio Frequency Identification Device). The work-piece crack detection method comprises the following steps: installing a fragile RFID electronic tag at a crack position to be detected of a detected work-piece in advance, so that the fragile RFID electronic tag is respectively connected and fixed with two sides of the crack position to be detected on the detected work-piece; and reading the installed fragile RFID electronic tag at the crack position to be detected on the detected work-piece by adopting an RFID electronic tag reader in need of detecting the crack of the detected work-piece, if reading successfully, judging that the crack is not generated at the crack position to be detected on the detected work-piece, and if not, judging that the crack is generated at the crack position to be detected. According to the invention, a work-piece is unnecessary to take down from equipment; and the work-piece crack detection method has the advantages of being rapid in identification speed, wide in identification range, easy to operate and control, simple, practical, small in equipment volume, flexible in shape, convenient in data format updating, good in safety and wide in application range and is capable of realizing penetrability and non-barrier detection.
