Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of commodity anti-theft, and particularly relates to an infrared remote control encodable electronic tag, an unlocking method thereof and an anti-theft system. BACKGROUND

[0002] Electronic article surveillance system, EAS for short, is one of the commodity security measures widely used in the current large retail industry. EAS was introduced in the United States in the mid-1960s, and was initially applied to the clothing industry. Now it has been extended to most countries and regions in the world, and the application field has also been extended to various industries such as department stores, supermarkets, books, etc.

[0003] The EAS system mainly consists of an antenna detector, an unlocking device (or a decoder) and an electronic anti-theft tag. The antenna detector is generally placed at the entrance or cash channel of the application site, and is used to detect whether the electronic tag on the commodity passing through the place has been deactivated or removed. When the electronic tag is not deactivated or removed, it will trigger an alarm when passing through the antenna detector, thereby reminding the cashier, customers and security personnel to handle it in time. The electronic tag is divided into two types: one is a soft tag, which can be pasted on the commodity for protection. This type of soft tag needs to use a decoder when it needs to be removed from the alarm. That is, the soft tag is deactivated by the decoder to achieve alarm removal. In this way, the commodity passing through the antenna detector after the normal transaction process will not trigger an alarm. However, the soft tag has the disadvantage of single protection mode (i.e. the soft tag generally has only one protection measure), and the soft tag is easily removed from the commodity by illegal persons (when removed illegally, it cannot alarm), and its commodity protection performance is relatively weak. The other is a hard tag. The hard tag needs to be attached to the commodity through nails, ropes, clips, etc. For example, CN 201130405Y, entitled "Commodity rope type anti-theft device". The hard tag generally includes a magnetic lock core, which needs to be unlocked with a magnetic tool. Moreover, the hard tag has an alarm device inside, which will alarm when the commodity is illegally separated (i.e. the hard tag generally has multiple protection measures), and its commodity protection performance is relatively strong.

[0004] At present, some valuable items are mainly protected by hard tags. Although the hard tag has an alarm anti-theft function against violent unlocking (such as cutting the anti-theft rope), the legal unlocking method of the hard tag can be easily used by people with ulterior motives (illegal persons). The illegal persons may unlock the magnetic lock core of the hard tag with a magnetic tool or even a magnet (in this case, the alarm device will not alarm), thereby causing the loss of the commodity. SUMMARY

[0005] Design purpose: To avoid the shortcomings in the background art, an infrared remote control encodable electronic tag with conventional protection function and password protection function, an unlocking method thereof and an anti-theft system are designed.

Then through the infrared remote controller 2, a user can operate a digital keyboard, input a password, and save the password by one key. Then the infrared transmitting end is inserted into the corresponding infrared receiving groove of the encodable electronic tag (that is, the infrared remote controller docking head 21 is inserted into the infrared remote controller docking port 11), after starting voltage authentication, the password setting key is pressed, and the password of the tag is set by one key.

[0030] The encodable electronic tag in the password protection state directly alarms when a steel wire rope is cut, an antenna is approached, self-positioning alarm, and the protection is removed by an unused password.

[0033] After step one and before step two, the infrared remote control 2 and the electronic tag body 1 will carry out voltage authentication, the voltage authentication process is as follows: first, the control chip one 24 controls the voltage authentication output module 23 in the infrared remote control 2 to output authentication voltage to the voltage authentication input module 13 in the electronic tag body 1, then the voltage authentication input module 13 can upload the collected authentication voltage amplitude to the control chip two 14, and the control chip two 14 can carry out voltage authentication on the authentication voltage amplitude, when the voltage authentication is successful, step two will be entered; the control chip one 24 can control the voltage authentication output module 23 to output authentication voltage, that is, the voltage authentication output module 2 outputs authentication voltage value which is variable (within a certain range), the user sends authentication voltage output value instruction to the control chip one 24 through the password input part 27, and the control chip one 24 can control the voltage authentication output module 23 to output authentication voltage according to the instruction. After the magnetic unlocking device is used to unlock the magnetic lock core in the electronic tag body 1 without carrying out the password protection alarm state release, when the steel wire is pulled out, the steel wire protection circuit is in an open state, at this time the control chip two 14 will receive an electric signal, the control chip two 14 will determine that it is a legal unlocking when it receives the electric signal generated by pulling out the steel wire within a certain time after the password protection alarm state release, otherwise it will be considered as illegal unlocking, and the control chip two 14 will alarm (that is, when the electronic tag body 1 receives the electric signal generated by pulling out the steel wire alone, it will alarm).

[0034] The electronic tag body 1 needs to be unlocked in time through the magnetic unlocking device within a certain time after the password protection alarm state is released, otherwise the control chip two 14 will control the electronic tag body 1 to re-enter the protection alarm state.

[0035] The electronic tag body 1 in the protection alarm state can be de-alarmed by inputting a matching password through the infrared remote controller 2 when the steel wire rope is cut, when it is close to the antenna, when it is positioning itself, or when it is not de-alarmed by using a password.
