[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0025] Figure 1 A schematic diagram illustrating the interaction between an electronic luggage tag and a radio frequency reader / writer device according to an embodiment of the present invention is shown. The electronic luggage tag 10 may include a radio frequency antenna 11, a radio frequency identification chip 12, and a processor 13, which are sequentially connected. The radio frequency reader / writer device 20 may include an antenna unit 21 and a processor 22, which are connected to the antenna unit 21. The radio frequency reader / writer device 20 may transmit data to the electronic luggage tag 10 via the antenna unit 21, so that the radio frequency identification chip 12 of the electronic luggage tag 10 receives the data transmitted by the radio frequency reader / writer device 20 via the radio frequency antenna 11. Alternatively, the radio frequency reader / writer device 20 may read data from the electronic luggage tag 10 via the antenna unit 21, so that the radio frequency identification chip 12 of the electronic luggage tag 10 transmits data to the radio frequency reader / writer device 20 via the radio frequency antenna 11. The processors 13 and 22 may be, for example, microcontroller units (MCUs). In the electronic luggage tag 10 according to this embodiment of the present invention, the processor 13 is communicatively connected to the radio frequency identification chip 12, for example, via predetermined pins, and the processor 13 may read or write data from the radio frequency identification chip 12. As an optional implementation, the communication connection may include, for example, an I2C bus connection, an SPI interface connection, a UART connection, or a GPIO connection.

[0026] Figure 2 FIG. 1 shows a flow chart of a method for waking up an electronic luggage tag according to an embodiment of the present invention. Figure 2 As shown, the electronic luggage tag wake-up method may include the following steps:

[0027] S11. The radio frequency reader / writer device reads the tag data of the radio frequency identification chip of the electronic luggage tag.

[0028] In this embodiment of the present invention, the electronic luggage tag is in a dormant state. The RFID reader / writer emits a continuous wave to the electronic luggage tag, thereby reading the tag data from the RFID chip of the electronic luggage tag. This tag data can be, for example, EPC (Electronic Product Code) data or TID (Tag Identification Number) data, which uniquely identifies the electronic luggage tag.

[0029] When there are multiple electronic luggage tags, such as when multiple suitcases are stacked together, it is difficult for the relevant operator to access the physical buttons of the electronic luggage tags. In this case, the RFID reader can read the tag data of the RFID chips of multiple electronic luggage tags, and each tag data corresponds to each electronic luggage tag.

[0030] S12. Obtain verification information based on the label data.

[0031] For example, a hash algorithm can be used to obtain verification information based on the tag data. The tag data is data that uniquely identifies the electronic luggage tag, so the verification information is also data that uniquely identifies the electronic luggage tag.

[0032] When there are multiple electronic luggage tags, the radio frequency reading and writing device can obtain multiple verification information according to the multiple tag data, and each verification information corresponds to each electronic luggage tag.

[0033] S13. Encrypt the instruction information and verification information to form an encrypted data string.

[0034] In this embodiment, the radio frequency reader / writer encrypts the instruction information and verification information to form an encrypted data string. During subsequent decryption, only the electronic luggage tag that knows the verification information can successfully decrypt it. The verification information is associated with the label data of the electronic luggage tag, and the label data is data that uniquely identifies the electronic luggage tag. Therefore, only the electronic luggage tag corresponding to the label data can successfully decrypt the encrypted data string, thereby preventing the instruction information from being sent to the wrong electronic luggage tag.

[0035] When there are multiple electronic luggage tags, the radio frequency reading and writing device encrypts the instruction information and each verification information respectively to form multiple encrypted data strings.

[0036] S14. Write the encrypted data string into the electronic luggage tag to wake up the processor of the electronic luggage tag.

[0037] In this embodiment, the RFID chip of the electronic luggage tag is communicatively connected to the processor via a predetermined pin. The write operation of the RFID reader / writer on the RFID chip of the electronic luggage tag causes the predetermined pin of the RFID chip to generate a level conversion, thereby waking up the processor.

[0038] When there are multiple electronic luggage tags, the radio frequency reading and writing device writes encrypted data strings to the multiple electronic luggage tags to wake up the processors of the electronic luggage tags.

[0039] S15. The processor reads the encrypted data string from the RFID chip.

[0040] When the processor is awakened, the processor checks the wakeup source. In this embodiment, when the processor finds that the wakeup source is the RFID chip, the processor reads the encrypted data string from the RFID chip, for example, reads the encrypted data string from a predetermined storage space of the RFID chip.

[0041] S16. The processor decrypts the encrypted data string.

[0042] In this embodiment, the processor can decrypt the encrypted data string using the tag data from the electronic luggage tag's RFID chip. Because the encrypted data string contains the tag data, only the electronic luggage tag corresponding to that tag data can successfully decrypt the encrypted data string. If the processor fails to decrypt, it indicates that the encrypted data string was not intended for the electronic luggage tag corresponding to the processor. In this case, the processor continues to sleep.

[0043] S17. When the decryption of the encrypted data string is successful, the processor executes the instruction corresponding to the instruction information.

[0044] If the encrypted data string is successfully decrypted, it indicates that the encrypted data string was sent to the electronic luggage tag corresponding to the processor. The processor then executes the instructions contained in the encrypted data string to perform the corresponding operation. In this embodiment, the instructions include but are not limited to: turning the electronic luggage tag's ink screen display on or off, modifying the luggage tag information, enabling the luggage tag's Bluetooth, silencing the luggage tag, and so on.

[0045] S18. The processor stores the execution result of the instruction in the radio frequency identification chip.

[0046] The processor can store the execution result of the instruction in a predetermined storage space of the radio frequency identification chip for reading by the radio frequency reading and writing device.

[0047] S19. After the electronic luggage tag executes the instruction corresponding to the instruction information, the radio frequency reading and writing device reads the execution result of the electronic luggage tag for the instruction.

[0048] After the radio frequency reading / writing device reads the result of the electronic luggage tag's execution of the instruction, the relevant operator holding the radio frequency reading / writing device can know whether the instruction is executed correctly.

[0049] In the electronic luggage tag wakeup method according to an embodiment of the present invention, the non-visual operation function of the electronic luggage tag's RFID chip is utilized to perform non-visual and secure operations on the electronic luggage tag. The electronic luggage tag can be woken up by an RFID reader / writer and instructions can be securely sent to the electronic luggage tag, causing the electronic luggage tag to execute the corresponding instructions without having to operate the electronic luggage tag's physical buttons. Furthermore, in the electronic luggage tag wakeup method according to an embodiment of the present invention, the RFID reader / writer can perform batch operations on multiple electronic luggage tags, avoiding situations where multiple suitcases are stacked together and the operator has difficulty accessing the physical buttons on the electronic luggage tags, thereby improving the operator's work efficiency.

[0050] Accordingly, an embodiment of the present invention provides a radio frequency reading and writing device, such as Figure 1As shown, the RFID reader / writer device may include an antenna unit 21 and a processor 22. The antenna unit 21 is used to read the tag data of the RFID chip 12 of the electronic luggage tag 10; the processor 22 is used to obtain verification information based on the tag data, encrypt the instruction information and verification information to form an encrypted data string, and control the antenna unit 21 to write the encrypted data string to the electronic luggage tag 10 to wake up the processor 13 of the electronic luggage tag 10.

[0051] Specifically, the tag data can be, for example, EPC (Electronic Product Code) data or TID (Tag Identification Number) data, which uniquely identifies the electronic luggage tag. When there are multiple electronic luggage tags, such as when multiple suitcases are stacked together, it is difficult for operators to access the physical buttons on the electronic luggage tags. In this case, the RFID reader / writer 20 can read the tag data from the RFID chips of multiple electronic luggage tags, with each tag data corresponding to each electronic luggage tag.

[0052] Furthermore, the RFID reader / writer 20 can utilize a hash algorithm to obtain verification information based on the tag data. The tag data uniquely identifies the electronic luggage tag, and therefore, the verification information also uniquely identifies the electronic luggage tag. If there are multiple electronic luggage tags, the RFID reader / writer can obtain multiple pieces of verification information based on the multiple tag data, with each piece of verification information corresponding to each electronic luggage tag.

[0053] Furthermore, the radio frequency reader / writer 20 encrypts the instruction information and verification information to form an encrypted data string. During subsequent decryption, only the electronic luggage tag that knows the verification information can successfully decrypt the information. The verification information is associated with the label data of the electronic luggage tag, and the label data is data that uniquely identifies the electronic luggage tag. Therefore, only the electronic luggage tag corresponding to the label data can successfully decrypt the encrypted data string, thereby preventing the instruction information from being sent to the wrong electronic luggage tag.

[0054] As some optional implementations of the present invention, the antenna unit 21 is further configured to read the result of the electronic luggage tag 10 executing the instruction corresponding to the instruction information after the electronic luggage tag 10 executes the instruction. This allows the operator holding the radio frequency reader / writer 20 to determine whether the instruction was executed correctly.

[0055] The embodiment of the present invention also provides an electronic luggage tag, Figure 1As shown, the electronic luggage tag may include an RFID chip 12 and a processor 13. The RFID chip 12 is configured to receive an encrypted data string written by an RFID reader / writer 20. The encrypted data string is encrypted from instruction information and verification information, and the verification information is derived from the tag data of the RFID chip 12. The processor 13 is in communication with the RFID chip 12, and the write operation of the RFID reader / writer 20 to the RFID chip 12 awakens the processor 13.

[0056] As some optional implementations of the embodiments of the present invention, the RFID chip 12 of the electronic luggage tag 10 is communicatively connected to the processor 13 via a predetermined pin. The write operation of the RFID chip 12 by the RFID reader / writer 20 causes the predetermined pin of the RFID chip 12 to generate a level conversion, thereby waking up the processor 13.

[0057] As some optional implementations of the present invention, the processor 13 of the electronic luggage tag 10 is further configured to read an encrypted data string from the RFID chip 12 and decrypt the encrypted data string. When the processor 13 is awakened, it checks the wakeup source. In this embodiment, if the processor 13 finds the wakeup source to be the RFID chip 12, it reads the encrypted data string from the RFID chip 12, for example, from a predetermined storage space within the RFID chip 12. In this embodiment, the processor 13 can decrypt the encrypted data string using the tag data from the RFID chip 12 of the electronic luggage tag 10. Because the encrypted data string contains the tag data, only the electronic luggage tag corresponding to the tag data can successfully decrypt the encrypted data string.

[0058] As some optional implementations of the present invention, the processor 13 of the electronic luggage tag 10 is further configured to execute instructions corresponding to the instruction information when decryption of the encrypted data string is successful. Successful decryption of the encrypted data string indicates that the encrypted data string was intended for the electronic luggage tag corresponding to the processor. Therefore, the processor executes the instructions contained in the encrypted data string to perform the corresponding operation. In this embodiment, these instructions include, but are not limited to, turning the electronic luggage tag's ink screen display on or off, modifying the luggage tag's information, activating the luggage tag's Bluetooth, muting the device, and so on. Conversely, if the processor decryption fails, it indicates that the encrypted data string was not intended for the electronic luggage tag corresponding to the processor. In this case, the processor remains dormant.

[0059] As some optional implementations of the embodiments of the present invention, the processor 13 of the electronic luggage tag 10 is further configured to store the result of executing the instruction in the RFID chip 12 for reading by the RFID reader 20. After the RFID reader 20 reads the result of executing the instruction by the electronic luggage tag 10, the operator holding the RFID reader can determine whether the instruction was executed correctly.

[0060] In the RFID reader / writer and electronic luggage tag according to embodiments of the present invention, the non-visual operation function of the electronic luggage tag's RFID chip allows for secure, non-visual operation of the electronic luggage tag. The RFID reader / writer can wake the electronic luggage tag and securely send instructions to it, causing the tag to execute the corresponding instructions without having to operate the tag's physical buttons. Furthermore, the RFID reader / writer according to embodiments of the present invention can perform batch operations on multiple electronic luggage tags, improving the efficiency of the relevant operators.
