Embodiment 1

[0031] Embodiment 1: a kind of frame type acoustic magnetic anti-theft tag decoder of this embodiment, such as figure 1 As shown, it includes a frame body 1 (the projection of the inner wall of the frame body is a rectangle of 35 cm X 20 cm), the frame body 1 is wound with a first coil 2, and the two ends of the first coil 2 are respectively electrically connected to the two output ends of the AC power supply, A bag 4 is arranged inside the frame body 1 , and the upper edge of the bag 4 is set on the outside of the frame body 1 .

[0032] The AC power supply outputs AC power to the first coil, and the first coil wound outside the frame generates an AC magnetic field under the action of the AC voltage. Bags can be plastic or paper bags. After the customer chooses the product, he pays by himself with his mobile phone, and puts the paid product into the bag of the frame. The anti-theft acoustic and magnetic label on the product is demagnetized and deactivated under the action of...

Embodiment 2

[0041] Embodiment 2: a kind of frame type acoustic magnetic anti-theft tag decoder of this embodiment, such as figure 2 As shown, it includes a frame body 1 (the projection of the inner wall of the frame body is 50 cm X 50 cm square), the frame body 1 is provided with an amorphous iron core 3, and a second coil 5 is wound on the amorphous iron core 3, and the second coil 5 The two ends are respectively electrically connected to the two output ends of the AC power supply, the amorphous iron core 3 is in an open state, and the amorphous iron core 3 is arranged vertically.

[0042] The second coil generates an AC magnetic field under the action of the AC voltage, which can deactivate the acoustomagnetic anti-theft labels on the commodities placed in the frame. The amorphous iron core has high saturation magnetic induction and low loss, and the amorphous iron core can also change the magnetic field distribution to produce a more effective demagnetization field. Therefore, the cu...

Embodiment 3

[0046] Embodiment 3: A frame-type acousto-magnetic anti-theft tag decoder of this embodiment includes a frame body, and frame-type distributed detection and excitation coils are arranged on the outside of the frame body and connected to at least one traditional tag decoder host.

[0047] The frame can be equipped with a traditional planar decoder host, but the detection and excitation coils are changed from planar to framed. The improved traditional tag decoder detects the acousto-magnetic anti-theft tag in the frame and sends out a short-term high-frequency AC magnetic field to deactivate the acousto-magnetic anti-theft tag.

Abstract

The invention discloses a frame type acoustomagnetic anti-theft tag decoder and method. The decoder comprises a frame, a first coil is wound on the outside of the frame, the two ends of the first coilare respectively electrically connected to two output ends of an alternating current power source, the frame is internally provided with a bag, and the upper edge of the bag is sleeved outside the frame. With the frame type decoder, the customer puts all the selected commodities into the frame after mobile phone self-service payment, and the alternating magnetic field generated by the coil on theframe deactivates the acoustomagnetic anti-theft tag on all the commodities put in the frame, avoiding the phenomenon that the customer does not know how to deactivate the acoustomagnetic anti-thefttag or the salesperson forgets to deactivate the acoustomagnetic anti-theft tag.

Description

technical field [0001] The invention relates to the technical field of acoustomagnetic anti-theft label decoding, in particular to a frame-type acoustomagnetic anti-theft label decoder and method. Background technique [0002] The existing decoder has a planar structure. After scanning the commodity price barcode, the store salesperson brings the label to a relatively small position on the plane surface of the known decoder (for example, only 3-5 cm in height), and triggers the decoder to send a high Frequency AC magnetic field, demagnetize the bias sheet in the tag and then deactivate it. However, with the popularization of mobile payment, it is possible for customers to scan codes and shop by themselves. When the customer scans the code to shop, the customer has no motivation or the mall does not want the customer to know how to specifically bring the label affixed to each product to a specific surface where the traditional decoder is very small for activation. Therefore...
