Data acquisition device based on RFID

The invention discloses a data acquisition device based on RFID, and particularly relates to the technical field of data acquisition, the data acquisition device comprises a storage rack, one side of the top end of the storage rack is fixedly provided with a lifting mechanism through bolts, the top end of the lifting mechanism is fixedly provided with an L-shaped bottom frame, the L-shaped bottom frame is provided with an auxiliary mechanism, and the auxiliary mechanism is fixedly connected with the storage rack. By arranging the auxiliary mechanism and using the driving mechanism in cooperation with the auxiliary mechanism, the collector can be driven to horizontally move by a certain distance, so that the position of the collector is automatically changed at a fixed distance, RFID data collection is sequentially performed on a plurality of articles, and a camera is used in cooperation with the auxiliary mechanism. The position of the RFID data acquisition tag of the next article is judged in advance, so tha
