Teaching and training reader control method for protecting RFID labels

Abstract

The invention provides a teaching and training reader control method for protecting RFID labels. The method has the advantages that redundant loads are not caused to students when the students carry out RFID experiments, and the students only need to carry out the experiments according to original manners; and the RFID labels are protected, so that the students do not need to worry the problem ofRFID label failure and can carry out the experiments boldly and confidently. According to the method, experimental operations for carrying out password change, inactivation and locking on the RFID labels are provided for the students, so that better experiment environment is provided for RFID experiments; the RFID labels are protected, so that an average service life of the RFID labels is prolonged, the investment costs, for the RFID labels, of schools are decreased and the capitals are saved; and when teachers process the RFID labels, initialization is carried out in batches, and different processing manners do not need to be adopted for the RFID labels with different states and contents, so that the operation is more simple and efficient.

Description

technical field [0001] The invention relates to the field of RFID technology, in particular to a control method for teaching and training readers for protecting RFID tags. Background technique [0002] The basic working principle of RFID technology is as follows: after the tag enters the magnetic field, the radio frequency signal sent by the reader sends out the product information stored in the chip (passive tag or passive tag) by virtue of the energy obtained by the induced current, or is actively sent by the tag For a signal of a certain frequency (Active Tag, active tag or active tag), the reader reads and decodes the information, and then sends it to the central information system for relevant data processing. [0003] RFID experiments are the main experimental courses for Internet of Things engineering majors. The main purpose of the courses is to enable students to understand and master various RFID standards and the actual operation of RFID tags through experiments. ...

Problems solved by technology

Therefore, the management workload of this type of RFID card is very large, and it is difficult to ensure that the key of a certain sector of the RFID card will not be modified into a key unknown to the laboratory manager, resulting in partial failure of the RFID card

[0008] (3) For a class of RFID tags containing inactivation instructions, such as ISO18000 tags, ISO18000-6C tags, etc., when the inactivation instruction is received, it will officially become invalid, resulting in waste of RFID tags

When the "lock" command is executed, its RFID tag cannot be modified again, resulting in the failure of the RFID tag

[0010] (5) During the experiment, students can only understand the experiment process through the computer. The computer is heavy and not conducive to movement, causing students to walk back and forth between the device and the computer, reducing the efficiency of the experiment; and students can only rely on the operation results to judge the status of the RFID tag. time consuming
