Embodiment Construction
[0023] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0024] See figure 1 , which is a structural diagram of an embodiment of the present invention based on the APSOC radio frequency identification RFID system, which includes an APSOC RFID reader-writer 11, an RFID electronic tag 12 and a server 13, and the RFID tag 12 communicates with the RFID reader-writer 11 through a wireless radio frequency mode Connected, APSOC RFID reader-writer 11 is connected with server 13.
[0025] Among them, each RFID tag 12 corresponds to a unique ID number, and the RFID tag 12 periodically sends wireless data to the reader, and the RFID reader 11 receives the information of the RFID electronic tag 11, and after receiving the signal, transmits the signal to the server 13. After the server 13 receives the data sent by the RFID reader, it analyzes and processes the data and saves it in the system.
[0026] See figure 2 , which is a str...
