The train is an important guarantee for domestic personnel capacity. It runs at full load and high speed every day. There are thousands of screws in a train compartment. Once a screw is loose, it may cause serious accidents, and at least it will bring inconvenience to people's life and production. Seriously, it endangers the safety of people's lives and properties, and causes huge social impact and economic losses
At present, the screw detection content of the carriage mainly includes two situations of loosening and falling off. Due to the limitation of equipment conditions, manual visual inspection and manual recording are mainly used. The number of screws is large and the location is widely distributed, and the workload of detection is very large.
Therefore, the current detection method has defects such as many human factors, high management costs, and low degree of informationization of inspection data.

The invention discloses a UHF RFID tag capable of detecting screw looseness, comprising a tag body and a follower. The tag body is provided with an RFID tag antenna and a tag chip. The tag chip is connected with an RFID tag antenna; being characterized in that a screw mounting hole is arranged at the center of the follower, and the shape of the screw mounting hole is matched with the screw head ofthe screw to be detected; The servo body sleeves the screw to be detected, and the screw head of the screw to be detected is embedded in the screw mounting hole, and the screw to be detected rotatesto drive the servo body to rotate correspondingly; The label body is arranged on the outside of the follower; two conductive sheets are arranged on the inner surface of the label body and are connected with the label chip through loose detection leads respectively. A conductive spring is embedded in the follower, and the two ends of the conductive spring extend outward and are connected with two conductive plates respectively. The invention can detect the loose state of the screw and realize automatic detection of the state of the screw. The UHF RFID tag can be widely used in all kinds of vehicles.
Description
technical field [0001] The invention relates to a UHF RFID tag, in particular to a UHF RFID tag capable of detecting screw looseness. Background technique [0002] With the development of society and the improvement of modernization, transportation plays an increasingly important role in social life and social production. The vast majority of ordinary people rely on trains for travel. The train is an important guarantee for domestic personnel capacity. It runs at full load and high speed every day. There are thousands of screws in a train compartment. Once a screw is loose, it may cause serious accidents, and at least it will bring inconvenience to people's life and production. Seriously, it endangers the safety of people's lives and properties, and causes huge social impact and economic losses. At present, the screw detection content of the carriage mainly includes two situations of loosening and falling off. Due to the limitation of equipment conditions, manual visual ins...
