RFID-based member relative displacement detection method

The invention discloses an RFID-based member relative displacement detection method. The steps include: 1) installing a fragile RFID electronic label in advance between members to be detected, and the fragile RFID electronic label being connected and fixed to the members to be detected; 2) when detection of relatively displacement of the members to be detected is needed, adopting an RFID electronic label reader to read the fragile RFID electronic label installed between the members to be detected, if the fragile RFID electronic label is read successfully, judging that no relative displacement occurs between the members to be detected, and otherwise judging that relative displacement occurs between the members to be detected. The RFID-based member relative displacement detection method provided by the invention has the advantages of fast identification speed, wide identification range, easy control, simplicity and practicability, small equipment size and flexible shape, convenient updating of data format, penetrability and barrier-free detection, good safety and wide range of application.
