Description

Wireless identification electronic lock with multiple security design

The present invention relates to a passive electronic lock, and more particularly, to a method and device for applying RFID (Radio Frequency Identification) chips and multi-protection protection, which is applied to safe transportation control and identification of containers or other objects. .

At present, more than 85% of the world's international trade in goods is transported through closed cabinets, which are transported by sea freight container transport and bonded trucks and freight train cabinets. Therefore, goods have been transported for a long time. The design and method of security monitoring mechanism for anti-dropping and anti-theft in the process are important issues for the rapid circulation of global trade. At present, most of the anti-drop and anti-theft security monitoring mechanisms still rely on traditional locks, mechanical locks, spring locks, Metal strips and other instruments are printed at the threshold and are manually checked to see if the printed number and appearance are integrity. However, the mechanical structure and appearance of the above-mentioned appliance are easily copied and reproduced under modern technology. The process is also not easy to leave traces. In addition to the visual inspection is difficult to distinguish and the anti-counterfeiting security effect is not good, there is no traditional electronic locks, and the requirements for global and international rapid logistics network clearance and transportation costs are reduced. Form a serious bottleneck.

Therefore, in recent years, with the development of RFID (Radio Frequency Identification) chips, the use of RFID chips in the production process has been difficult to forge and copy. One code and combined with the traditional mechanical seals to produce patents related to electronic locks (or electronic seals) for container security. The electronic lock of the container is divided into active electronic lock and passive electronic lock according to whether it has extra battery power to the RFID chip. The active electronic lock has a complicated internal structure and high production cost, and is generally recycled and reused, due to the extra battery power supply. Therefore, the warning signal can be automatically issued when the unlocking is broken, and the structure of the passive electronic lock is relatively simple, and there is no battery power inside, and the working principle is that the electromagnetic wave energy is emitted by the external RFID reader. After the electromagnetic wave is absorbed by the passive RFID electronic lock, the RFID chip is excited, and the related information in the RFID chip is reversed to the electromagnetic signal return mode to the RFID reader to achieve the function of information exchange.

As mentioned above, the passive RFID electronic lock used in the container is combined with the traditional mechanical seal and the radio frequency identification chip in common use, such as I285700, CN2531066Y, M328051, I292007 and other related patents. The emphasis is on radio frequency identification. There must be a conduction mechanism between the RFID chip and the antenna to receive/transmit the general principle of signal transmission and conduction. The wafer and the antenna are respectively placed in the two ends or the same end of the latch and the pin holder of the conventional mechanical seal. After the latch of the mechanical seal and the two parts of the latch seat are locked on the container door, the radio frequency identification chip and the antenna are turned on and can be used with the external reader as a confirmation whether the container door is locked with the radio frequency identification electronic lock. It has been opened, and its lock on the container door relies on a spring-loaded buckle in the mechanical seal pin holder to hold the groove of the bolt body. However, when used in practice, external force can be utilized. It is easy to wear the groove of the metal body buckle of the plug or the spring buckle in the bolt seat can be easily removed by a simple tool. After the above-mentioned destruction action, the adhesive tape or glue is fixed, and the appearance is not easy to detect. It is known through the actual intensive pull of the inspectors, but under the fast-track customs information flooding, simplified manual inspection or manual inspection is easily neglected by trusting RFID technology, and can be transmitted through a single wire connection between the radio frequency identification chip and the antenna. When the general principle of electronic signals is turned on and working, although it has been improved compared with the original mechanical type, in this case, repeated use or simple conductors as a bridge between the radio frequency identification chip and the antenna to form an unsafe conduction will be formed. It's very easy and doesn't leave any records, which in turn creates a big hole in the security of using passive RFID tags.

Therefore, how to increase the safety of container transportation, improve the identification of container transportation, and reduce the waste of manpower and time is an important technical problem that the container shipping industry needs to solve urgently.
