The article detection scheme of the embodiment of the specification can be applied to an offline intelligent shopping scene, such as an unmanned supermarket, an unmanned coffee shop or an unmanned sports store. In these application scenarios, it is necessary to automatically detect and settle the items that the user needs to purchase. With reference to fig. 1A and 1B, as shown in fig. 1A, the intelligent shopping scene diagram is shown according to an exemplary embodiment in this specification, as an example, a user purchases an article in an unmanned supermarket, wherein an acoustic-magnetic tag and an RFID tag are attached to the article, then, the user can reach an exit of the supermarket where the article detection system of this embodiment is deployed, the article detection system can detect information of the article selected by the user, and the article omission can be effectively prevented by the acoustic-magnetic tag, the RFID tag, and a corresponding relationship between the acoustic-magnetic tag information of the article and the RFID tag information. For convenience of illustration, in fig. 1A, the acoustic magnetic detection module, the RFID detection module, and the processing module are respectively illustrated by using independent devices, and in actual use, the acoustic magnetic detection module, the RFID detection module, and the processing module may also be combined and integrated in the same device as needed, which is not limited in this embodiment.
FIG. 1B is a block diagram of an article detection system shown in accordance with an exemplary embodiment of the present description, including:
a storage module 11, configured to: storing the corresponding relation between the RFID label information and the acoustic magnetic label information of the article.
An acousto-magnetic detection module 12 for: and detecting whether an article is in the detection area and the acoustic magnetic label information of the article.
An RFID detection module 13 configured to: it is detected whether an item is within the detection zone and the item's RFID tag information.

Specifically, the articles in the embodiments of the present specification have an acoustic magnetic tag and an RFID tag attached thereto.
The acoustic magnetic label is an electronic anti-theft label based on acoustic magnetic technology, and comprises soft labels, hard labels and the like. As shown in fig. 1C, the acousto-magnetic detection module includes a transmitting antenna and a receiving antenna, the transmitting antenna transmits a transmitting signal (alternating magnetic field) with a set frequency (a common standard is 58kHz), a detection area is formed between the transmitting antenna and the receiving antenna, and then the resonance principle of electromagnetic waves is used to search whether an acousto-magnetic tag exists in a specific range (that is, an acousto-magnetic tag that has not been demagnetized exists). The acoustic magnetic label comprises amorphous metal which is arranged in a disordered mode, the amorphous metal is cut into 58kHz size, and a resonance signal is generated when the acoustic magnetic label enters a detection area and is received by a receiving antenna. Therefore, when the acoustic magnetic label enters the detection area, the acoustic magnetic label is subjected to fire resonance by the pulse information set, and when the pulse signal stops, the acoustic magnetic label continues to resonate to send out the resonance signal with the same frequency, so that the acoustic magnetic detection module can determine that the acoustic magnetic label is present.
The RFID tag is a tag based on Radio Frequency Identification (RFID) technology, and is composed of a coupling element and a chip, and each RFID tag has a unique code, that is, a unique identifier. The RFID detection module comprises a reader, and the reader sends a radio frequency signal with a specific frequency through a transmitting antenna to form a detection area. When the RFID tag enters a detection area, induced current is generated, so that energy is obtained, the electronic tag is activated, and the electronic tag sends out self-encoding information through a built-in radio frequency antenna; the receiving antenna of the reader receives the modulation signal sent from the RFID label, the modulation signal is transmitted to the reader signal processing module through the antenna regulator, and the coded information of the RFID label is transmitted to the background processing module connected with the reader for relevant processing after demodulation and decoding.
The acoustic magnetic label is a label without carrying an identifier, and the RFID label is a label with an identifier. Articles in the embodiments of the present description are attached with an acoustic magnetic tag and an RFID tag, and a correspondence between RFID tag information of the articles and acoustic magnetic tag information may be bound in advance, as an example, each article may be configured with an article identifier, and the articles are distinguished by the article identifier; on the other hand, after the acoustic magnetic label and the RFID label are attached to the article in advance, the corresponding relationship between the article identifier, the RFID label information, and the acoustic magnetic label information is recorded and stored, optionally, the storage manner may be stored in a local database or a remote database, and the processing module of the article detection system may access the database and read the stored corresponding relationship. Optionally, the article identifier may further correspond to article information such as article price and article name, so that after the RFID tag information is detected, the article information is determined according to the corresponding article identifier, thereby automatically completing the settlement process.
According to the embodiment, the acoustic magnetic label information can be used for being bound with the RFID label information of the article, and when a user carries the article to pass through a detection area, the processing module can obtain the detection result of the acoustic magnetic detector, the RFID detector and/or the corresponding relation, so that whether the article missing detection exists or not is determined.
In some examples, the category of the acoustic-magnetic tag may be one, that is, all the articles are attached with the same acoustic-magnetic tag, in this case, if the RFID detection module does not detect an article due to human or RFID tag being blocked, and the acoustic-magnetic detection module detects an article, it may be determined that there is an article missing detection due to the collision of the detection results of the two.
In other examples, there may be a missing detection situation in the acoustic magnetic detection module, and there may be a possibility that a user carries many articles and part of the articles are missed, in order to implement a more reliable article detection scheme, the acoustic magnetic tags in the embodiments of this specification may include multiple categories, resonance signals generated by different categories of acoustic magnetic tags have different frequencies, the acoustic magnetic tags generating resonance signals of the same frequency belong to the same category, and the acoustic magnetic tag information includes: and the resonant signal frequency generated by the acoustic magnetic label corresponds to the category. In this way, the number of the acoustic magnetic labels is at least more than 1, and the reliability of detection is positively correlated with the number of the types.
As an example, assuming that there are N types of acoustic-magnetic tags, a certain type of acoustic-magnetic tag may be assigned to an article by using a random or set rule, and based on this, the storage module may have a correspondence relationship between RFID tag information of the article and the type of acoustic-magnetic tag. In some examples, the acousto-magnetic detection module may include N classes of acousto-magnetic detection modules that respectively detect the classes of acousto-magnetic labels. In other examples, N types of acousto-magnetic detection functions may be integrated into the same acousto-magnetic detection module.
Taking 3 categories of acoustic-magnetic labels as an example, assume that a user holds 6 items:
| article with a cover | Class of acousto-magnetic labels | RFID tag information |
| 1 | Type A | RFID0 |
| 2 | Type B | RFID1 |
| 3 | Type C | RFID2 |
| 4 | Type A | RFID3 |
| 5 | Type B | RFID4 |
| 6 | Type C | RFID5 |
When the user gets into in the detection zone, if the acoustomagnetic detection module has detected Type A, the RFID label information that RFID detection module detected includes: RFID2 and RFID 4. By querying from the storage module through Type a, RFID2 and RFID4, neither processing module RFID2 nor RFID4 is bound to Type a, that is, the detected acousto-magnetic label information and the detected RFID label information do not match the stored correspondence, and therefore, it can be considered that there is an article missing. The reason for the missed detection of the article can be due to the intentional theft by the user, or the detection capability of the device is insufficient, or the RFID tag is shielded by a body, metal or the like.
After the processing module determines that the article missing detection exists, a prompt message can be sent out; as an example, the processing module may be connected to a display screen, a player, and the like, and may display a prompt message through the display screen, play a prompt message in a voice form through the player, or push the prompt message to a personal device of a user through a server. Based on this, when the RFID blocking behavior occurs, the movement of the item can be completed by reminding the user until the RFID0 or the RFID3 bound with the TypeA is detected.
