Fig. 1 shows a schematic structural diagram of an intelligent holding cabinet according to an embodiment of the present invention, and fig. 2 shows a schematic installation diagram of an RFID antenna according to an embodiment of the present invention.
Referring to fig. 1, the intelligent holding cabinet includes a holding cabinet body 110, an electrically controlled lock 120, a manually controlled lock 130, an article recognition device, an electrically controlled lock controller 150, an inventory controller 160, and a central controller 170.
The central controller 170 is connected to the inventory controller 160, the inventory controller 160 is connected to the electric control lock controller 150, the electric control lock controller 150 is connected to the electric control lock 120, and the electric control lock 120 and the manual control lock 130 are disposed on the storage cabinet body 110.
It should be noted that, the electric control lock 120 and the manual control lock 130 may be lock bodies commonly used in the market, as long as it is ensured that when the electric control lock 120 fails, the manual control lock 130 may be used to unlock, that is, the cabinet door of the storage cabinet body 110 may be opened.
In this embodiment, referring to fig. 2, the article identification device includes an RFID antenna 140 and an RFID card reader, at least one RFID antenna 140 is disposed on the bottom surface of the storage cabinet body 110, at least one RFID antenna 140 is disposed on the side surface of the storage cabinet body 110, and the RFID card reader is connected to the RFID antenna 140, so that it can be ensured that the articles in the storage cabinet body 110 are all within the coverage range of the RFID wireless signal. Alternatively, one RFID antenna 140 may be provided on each of the bottom and side surfaces of the holding cabinet body 110.
With continued reference to fig. 1, an electrically controlled lock controller 150 is connected to the electrically controlled lock 120 for controlling the unlocking of the electrically controlled lock 120.
The inventory controller 160 is connected to the electric control lock controller 150 and the RFID card reader, respectively, and is configured to send an unlocking instruction to the electric control lock controller 150 and/or receive article storage information identified by the RFID card reader.
The central controller 170 is connected to the inventory controller 160, and is configured to control the inventory controller 160 to send an unlocking instruction to the electrically controlled lock controller 150, and/or to receive the article storage information received by the inventory controller 160.

Alternatively, if the item to be preserved is a metal item, a metal-resistant RFID tag may be affixed to the metal item to be preserved.
In some embodiments, to prevent the articles inside the storage cabinet body 110 from being misread, the following method may be adopted. The method comprises the following steps:
a time slot with a preset number of time slots is allocated to broadcast to all RFID tags, and each RFID tag randomly selects one time slot.
Wherein the predetermined number may be 2QAnd Q is a positive integer of 1 or more. It should be noted that all slot slots in one slot broadcast have sequential numbering. For example, when Q is 2, there are 4 slot slots in the slot broadcast, and in this case, the order of slot slots is numbered 1, 2, 3, and 4.
When the inventory frame is initiated, the sequential number of the slot selected by each RFID tag is decremented by 1.
Wherein the inventorying frame may be one frame signal having a specific length.
And when the sequence number of the time slot is 0, the RFID label corresponding to the time slot sends data information to the RFID card reader, wherein the data information comprises a random verification code.
The random verification code can be a random number of 0-65535.
And the RFID card reader receives and analyzes the data information, and sends the random verification code obtained by analysis to the RFID label as a verification character.
And if the verification character received by the RFID label is the same as the random verification code sent by the RFID label, sending article storage information to the RFID card reader.
The item keeping information may include the type of item, the number of items, the storage location, and what items are stored therein. For example, an ID number (e.g., a set of data codes) may be used to indicate the type of item, the number of items, the storage location, and what items are stored.
In this embodiment, if the RFID reader cannot resolve the random verification code, the RFID tag reselects a new slot, and sends the data information carrying the random verification code again when the sequence number of the slot is 0.
In this embodiment, in a checkpoint frame, if the probability that the RFID card reader analyzes the random verification code is smaller than a first preset threshold, it indicates that the number of RFID tags is greater than the number of time slots, and the number of time slots needs to be increased, that is, the value of Q needs to be increased; if the time for receiving the data information carrying the random verification code by the RFID card reader is less than the first preset threshold, it indicates that the number of the RFID tags is less relative to the number of the time slots, and the number of the time slots needs to be reduced, that is, the value of Q is reduced.
In this embodiment, when the sequence number of the selected time slot is 0, the RFID tag sends data information carrying a random verification code to the RFID reader, the RFID reader analyzes the random verification code when receiving the data information, and sends the random verification code to the RFID tag as a verification character, and when the verification character received by the RFID tag is the same as the random verification code sent by the RFID tag, the RFID tag sends article storage information to the RFID reader, so that the identification rate of the article to be stored can be improved, and the article to be stored is prevented from being missed.
Fig. 3 shows a schematic structural diagram of an intelligent holding cabinet according to another embodiment of the present invention.

In some embodiments, each storage cabinet body 110 is welded seamlessly, a shielding material is sprayed in the storage space inside the storage cabinet body 110, a shielding strip is pasted on the cabinet door of each storage cabinet body 110, and after the cabinet door is closed, RFID wireless signals are prevented from leaking, so that a cross-reading phenomenon is prevented when RFID tags are identified, that is, an RFID antenna 140 in one storage cabinet body 110 reads an RFID tag in a next storage cabinet body 110.
In some embodiments, to prevent the items in the cabinet from being repeatedly checked, a tag deduplication module may be disposed in the holding cabinet body 110, and the tag deduplication module is configured to read an EPC value in the item holding information sent by the RFID tag, where the EPC value is used to represent the item holding information to which the RFID tag is bound. For example, some number of bits in the EPC value may be used to represent item retention information.
Specifically, when checking the items stored in the current storage cabinet body 110, the tag duplication elimination module reads EPC values in item storage information sent by RFID tags attached to all the stored items in the storage cabinet body 110, compares the read EPC values in the new item storage information with EPC values in the checked item storage information, and filters out item storage information with duplicate EPC values, so as to ensure uniqueness of the RFID tags and avoid duplicate checking of the same item in the storage cabinet body 110.
In some embodiments, in order to prevent items in other holding cabinet bodies 110 from being checked during the process of checking the items in the current holding cabinet body 110, a tag read-through deduplication module may be disposed in the holding cabinet body 110, where the tag read-through deduplication module includes a signal strength comparison deduplication unit and a tag attribute comparison deduplication unit.
The signal strength comparison and deduplication unit is used for reading the RSSI value returned when the article storage information sent by the RFID tag is sent, and the tag attribute comparison and deduplication unit is used for reading the EPC value in the article storage information sent by the RFID tag.
In the present embodiment, the RSSI value is used to indicate the strength of a signal returned when reading the item preservation information, and the EPC value is used to indicate the item preservation information to which the RFID tag is bound.
Specifically, when an item in one storage cabinet body 110 needs to be checked, the item storage information of the current storage cabinet body 110 is first stored as tag data, and the tag data may be represented by an EPC value and an RSSI value, for example, some bits in the EPC value represent the item information data, and the RSSI value represents the signal strength of the tag in the current storage cabinet body 110. It should be noted that the RSSI value may be a specific value or a specific range of values.
Then, the RFID tag on the article to be checked sends article storage information, the RSSI value in the article storage information of the duplication removing unit is compared through signal strength, the EPC value in the article storage information is read through the tag attribute comparison duplication removing unit, when the EPC values in the article storage information are the same, the article to be checked is located in the current storage cabinet body 110 or the other storage cabinet body 110 next to the current storage cabinet body 110, the RSSI value returned when the article storage information is read by the RFID card reader needs to be continuously compared at the moment, and if the RSSI value is the same as the RSSI value in the tag data or falls into the RSSI value range, the article to be checked is located in the current storage cabinet body 110 and is checked; otherwise, the article to be checked is removed, and the data is not stored.
In this embodiment, whether the article storage information sent by the RFID tag read by the RFID card reader belongs to the current storage cabinet is identified through the tag duplication removal module and the tag reading duplication removal module, so that the article storage information of the RFID tag not belonging to the current storage cabinet can be removed, and the inventory identification rate of the article to be stored is improved.
In some embodiments, each storage cabinet body 110 is provided with a transceiver module for adapting the connection between the RFID antenna in each storage cabinet body 110 and the RFID reader/writer, so as to solve the problem of reading by mistake when identifying the RFID tag.
