[0002] The wire electronic seal is an electronic seal used in metering devices, tank trucks, containers, and logistics. It uses a globally unique RFID chip inside and has an anti-counterfeiting function. The traditional RFID wire seals on the market are passive and have two fatal problems:
[0003] 1. Low security: Since the seal is passive, the intermediate process cannot be detected, so the wire can be cut, and a new wire can be replaced after the crime, but in subsequent operations it is impossible to determine whether it has been cut;
[0004] 2. Complicated operation: The tag status cannot be obtained through quick inventory of RFID devices, but needs to be obtained by reading special register bits in the reserved area. The tag status conversion requires a large number of RFID interactive operations, the software integration is cumbersome, the execution efficiency is low, and the user experience is poor.
[0005] Based on this, the utility model proposes an ultra-high frequency steel wire sealing label to solve the above problems. Utility Model Content
[0006] In order to overcome the defects in the above-mentioned prior art, the utility model provides an ultra-high frequency steel wire sealing tag, which is controlled by relevant circuits inside the seal, and the intermediate process is detectable and traceable, so as to solve the problem that after the traditional RFID seal is broken, the steel wire is pulled out and replaced with a new steel wire, and the broken state can be restored. The locking steel wire can be directly inserted into the seal to lock it, and the seal can be broken by cutting the steel wire. The locking and breaking do not require the intervention of the RFID reader, and the breaking status can be monitored in real time. RFID is used throughout the query and interaction process, and information interaction is controlled contactlessly.

DETAILED DESCRIPTION
[0029] In order to better illustrate the content of the utility model, the following is a description with reference to the accompanying drawings and implementation examples:

[0033] Furthermore, a control chip 62 and a power interface 65 are also provided in the control circuit 61 , and the power interface 65 circuit is connected to a battery 66 placed in the placement chamber 9 .
[0034] Furthermore, two lock connection ends 63 located just above the metal lock 4 are provided on one side of the control circuit board 6 close to the lock chamber 2 , and the lock connection ends 63 are circuit-connected to the metal lock 4 .
[0035] Furthermore, an RFID tag antenna (not shown) is provided on one side of the control circuit board 6 away from the lock chamber 2 .
[0036] Furthermore, RFID communication is used to encrypt and transmit interactive information, and the key dispersion principle is adopted, one signature and one password, one time and one password. The EPC area and USER area have large capacity to meet various customized application requirements, such as security authentication, historical record tracing, real-time monitoring, circulation control, etc.
[0037] Furthermore, the battery 66 includes but is not limited to a button battery.
[0038] Furthermore, the control chip 62 is a microcontroller.
[0039] Specifically, the initial state of the sealing tag is an unlocked state, at which time the microcontroller is in a low power consumption state;
[0040] When the locking wire 8 is inserted, the detector in the control circuit 61 is connected to the locking wire 8 through the metal lock 4. The control circuit 61 detects that the locking wire 8 is inserted (the circuit where the locking wire 8 is located is connected), and reports the signal to the microcontroller. The microcontroller is awakened and enters the working state, changes the lock body state to the locked state, and wakes up the chip of the radio frequency circuit, writes the locked state into the radio frequency chip, and after the data is completely written, the radio frequency chip is turned off, and at the same time, the microcontroller re-enters the low power consumption state;
[0041] At this time, the state of the sealing tag has changed to locked state, and the external RFID reader or handheld device can read the RFID radio frequency antenna to access the radio frequency circuit and obtain the state of the sealing tag;
[0042] When the locking wire 8 is disconnected, the control circuit 61 detects that the locking wire 8 is disconnected (the circuit where the locking wire 8 is located is disconnected), and reports a signal to the microcontroller, which is awakened and enters a working state, changes the lock body state to a broken state, and wakes up the chip of the radio frequency circuit, writes the broken state into the radio frequency chip, and after the data is completely written, turns off the radio frequency chip, and at the same time, the microcontroller re-enters a low power consumption state, and the broken tag will no longer be awakened by the breaking detection circuit;
[0043] At this time, the seal tag status has changed to the broken state. The external RFID reader or handheld device can read the RFID radio frequency antenna to access the radio frequency circuit and obtain the status of the seal tag.
[0044] Through the RFID reader, a signal can be sent to the RFID circuit through the RFID RF antenna to interact with the microcontroller to obtain information such as the time of breaking the seal / operator;
[0045] The UHF RFID reader can quickly obtain the status of the seal by counting the EPC. There are three states of the seal as follows:
[0046] Unlocked: The locking wire is not inserted, and the sealed inventory is in the unlocked state;
[0047] Locked: After inserting the locking wire into the metal lock, tighten it, sign and seal it automatically, and record the locking time. At this time, the equipment is counted as locked;
[0048] Broken: When the steel wire is cut, the seal immediately changes to the broken state and the locking time is recorded. This state cannot be restored (even if a new steel wire is replaced and locked again, the state cannot be restored); at this time, the equipment inventory is in the broken state.
[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the technical solution of the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the spirit and scope of the technical solution of each embodiment of the utility model.
