Specifically, the handheld terminal adopts a terminal device with a model of T60RT and a processor of 8-core 2.0GHz.

[0041] The passive electronic seal lock comprises a chip module, a motor module, an RFID tag, a lock beam and a lock body.

[0042] The passive electronic seal lock comprises two groups of RFID tags. One group of the RFID tags is an identity identification tag for identifying the identity of the electronic seal lock, and the other group of the RFID tags is a state identification tag for judging the state of the electronic seal lock. Each group of the RFID tags stores a group of EPC numbers.

[0043] The chip module sends a driving instruction to the motor module based on the RFID tag identification information, so as to complete the sealing operation of the electronic seal lock.

[0044] It should be noted that the identity identification tag is independently arranged in the lock body, and the handheld terminal determines the identity information of the electronic seal lock by reading the EPC number. The state identification tag internally comprises a detection part, which leads out two metal antennae. The two groups of metal antennae are respectively built in the lock body of the electronic seal lock, one end of which is located at the fixed position of the lock beam and connected with the fixed end A of the lock beam, and the other end is located at the lock tooth position and used for being connected with the movable end B of the lock beam when the movable end B of the lock beam is inserted into the lock body.

[0045] Please refer to Figures 3-4 In the present embodiment, the handheld terminal is connected with the electronic seal lock in the mode of data line.

[0049] S103, the handheld terminal supplies power to the motor drive in the passive electronic seal lock through the data line;

[0050] S104, when the chip module in the electronic seal lock judges that the received sealing instruction is a correct instruction, the motor drive starts to work, drives the lock teeth to close, and bites the movable end B of the lock beam, realizing the sealing process of the passive electronic seal lock;

[0051] b, when the passive electronic seal lock is unsealed:

[0052] S201, the operator first inserts the data line A end into the electronic seal lock, and the data line B end into the handheld terminal;

[0053] S202, the APP in the handheld terminal issues an unsealing instruction to the chip module in the passive electronic seal lock through the data line;

[0054] S203, the handheld terminal supplies power to the motor drive in the passive electronic seal lock through the data line; when the chip module in the electronic seal lock judges that the received unsealing instruction is a correct instruction, the motor drive starts to work, drives the lock teeth to open, and releases the movable end B of the lock beam;

[0055] S204, the operator can now pull out the movable end B of the lock beam from the lock hole, realizing the sealing process of the passive electronic seal lock.

[0056] In another embodiment, the passive electronic seal lock sealing state judgment process is as follows:

[0057] c, when the passive electronic seal lock is in the sealing state:

[0058] S301, when the movable end B of the lock beam of the passive electronic seal lock is inserted into the lock body, the A and B ends of the lock beam are connected with the state judgment RFID tag respectively, due to the conductivity of the lock beam, causing the state judgment area of the state judgment RFID tag to form a short circuit;

[0059] S302, using the RFID function of the handheld terminal to patrol the library, the EPC information of the identity identification RFID tag can be read, but the EPC information of the state judgment RFID tag cannot be read;

[0060] S303, judging by the background management platform and the handheld terminal APP, the state of the passive electronic seal lock at this time is the sealing state;

[0061] d. When the passive electronic seal lock is in the unsealing state:

[0062] S401, when the movable end B of the lock beam of the passive electronic seal lock is not inserted into the lock body, the lock beam is only connected with the state judgment RFID tag at the fixed end A, and the state judgment area does not form a short circuit;

[0063] S402, using the RFID function of the handheld terminal to patrol the warehouse, the handheld terminal can read the identity RFID tag EPC information and the state judgment RFID tag EPC information at the same time;

[0064] S403, judging by the background management platform and the handheld terminal APP, the state of the electronic seal lock at this time is the unsealing state.

[0065] In another embodiment, the handheld terminal is used to associate the electronic seal lock with the handheld terminal by reading the EPC number of the RFID tag in the electronic seal lock; and is also used to connect the passive electronic seal lock with the data line of the handheld terminal to supply power to the motor module of the passive electronic seal lock, so as to realize the sealing and unsealing functions of the electronic seal lock;
