The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

In modern economic life with self-service becoming more and more popular, supermarket stores, production workshops, families, logistics distribution and other occasions, various storage devices, such as self-service selling freezers, consumable storage cabinets, warehouse cabinets, logistics containers and other devices, are increasingly widely used, and the automation level is continuously improved. Taking the freezer as an example, the freezer is an important carrier for storing and transporting refrigerated products in short distance, and can be divided into a horizontal freezer, a vertical freezer and the like. In addition to a cabinet body, a cabinet door and a refrigeration control system with set specifications, a traditional self-service intelligent freezer to which a Radio Frequency Identification (RFID) technology is applied is also provided with an RFID antenna, an RFID module and a background server in the cabinet body.

The refrigeration control system mainly comprises a main control board, a compressor, lighting equipment and the like, wherein the background server controls the main control board through instructions, and the main control board controls the RFID module to drive the RFID antenna so as to scan RFID tags attached to various articles in the cabinet body in real time. The RFID module can further obtain the article information of the article to which the RFID tag belongs by the radio frequency signal corresponding to the RFID tag received by the RFID antenna, and the article information is reported to the background server by the main control board, so that the background server can execute management such as inventory updating, settlement, bill issuing and the like according to the real-time article information. The main control board may control the RIFD antennas connected to the antenna ports of the RFID module to operate independently, for example, all the antennas operate simultaneously or at different times, respectively, by providing the RFID module with trigger signals of different antenna ports independently. The control of the master control board on the RFID module is simple to realize, high in reliability and flexible in setting, and therefore the RFID module is widely applied to vending machines and intelligent logistics containers waiting for self-service equipment. However, the traditional storage device still has low working efficiency in stock checking and settlement scanning, and cannot meet the more severe high-efficiency requirements in production and life.

An RFID tag is an electronic tag that records certain information based on radio frequency identification technology. The RFID is a non-contact automatic identification technology, data in an RFID label is automatically identified through a radio frequency signal, or data is written in by the RFID, the radio frequency identification technology does not need manual intervention, and the RFID can work in various severe environments. In one example, an RFID tag includes a coupling element and a chip, the coupling element electrically connecting the chip. Further, the RFID tag is an active RFID tag, a semi-active RFID tag, or a passive RFID tag. Preferably, the RFID tag of the article is an Ultra High Frequency (UHF) electronic tag, and the corresponding RFID read-write module is an UHF RFID read-write module. The UHF electronic tag belongs to a passive electronic RFID tag, is in a passive state when the RFID reading and writing module is out of an induction range, and extracts a power supply required by work from electromagnetic waves emitted by the RFID reading and writing module when the RFID reading and writing module is in the induction range. The UHF electronic tag has the characteristics of long identification distance, high identification degree, strong anti-collision capacity and good expandability, so that the refrigeration equipment has good identification capacity.

Referring to fig. 1, an embodiment of the present invention provides a storage device 100, which includes a cabinet 12, a cabinet door 14, a first antenna 16, a second antenna 18, an RFID module 20, and a main control module 22. The cabinet 12 is formed with a storage chamber for receiving items carrying RFID tags. The cabinet door 14 is structurally coupled to the cabinet 12 for enclosing the cabinet 12. The first antenna 16 is disposed inside the cabinet body 12 or on the cabinet door 14 and located at one side of the storage cavity. The first antenna 16 is used for sensing the radio frequency signal of each RFID tag in the storage cavity. The second antenna 18 is disposed outside the cabinet 12 or on the cabinet door 14 and located outside the storage cavity. The second antenna 18 is used to sense the radio frequency signal of the RFID tag of each item outside the storage compartment awaiting settlement. An RFID module 20 is disposed on the cabinet 12 and communicatively couples the first antenna 16 and the second antenna 18. RFID module 20 is configured to receive each radio frequency signal and obtain item information corresponding to each item. The main control module 22 is arranged on the cabinet body 12, and is in communication connection with the RFID module. The main control module 22 is used for reporting the article information to the server, triggering the first antenna 16 to stop working when the cabinet door 14 is unlocked, and triggering the second antenna 18 and the first antenna 16 to start working respectively when the cabinet door 14 is locked.

It can be understood that, in the storage device 100, the cabinet 12 is a main body bearing structure of the storage device 100, and can be used for bearing various articles to be refrigerated or stored at normal temperature, and bearing the structures of the cabinet door 14, the first antenna 16, the second antenna 18, the RFID module 20, the main control module 22, and the like. The storage device 100 may further include other components, such as a compressor and a lighting device electrically connected to the main control module 22, which are not described in this specification. The master control module 22 may be a master control board of a conventional self-service intelligent storage device, such as a master control board of a refrigeration control system of a conventional self-service intelligent freezer. The server can be a background server of the traditional self-service intelligent storage device. The items of each type may be, but are not limited to, food, consumables, pharmaceuticals, or logistics packages.

The RFID module 20 may be fixed on an inner surface of the cabinet 12, for example, on any one of the side wall panels of the cabinet 12 and on a surface on one side of the storage cavity, on a bottom panel of the cabinet 12 and on a top cover panel of the cabinet 12 and on a surface on one side of the storage cavity, or fixed on the cabinet door 14 and on a surface on one side of the storage cavity, or embedded in the cabinet 12 or the cabinet door 14, for example, embedded in a body wall of the cabinet 12 or a door panel interlayer of the cabinet door 14, and the specific position may be determined according to a need of receiving the radio frequency signal transmitted back by the first antenna 16 and the second antenna 18. The first antenna 16 and the second antenna 18 may be the same type of RFID antenna or different types of RFID antennas, as long as they can sense the RFID tag on each article. It should be noted that the positions of the RFID modules 20 illustrated in the drawings are only for illustrating the communication connection relationship between the RFID modules 20 and the first and

second antennas

16 and 18, and do not limit the actual installation positions of the RFID modules 20. It should be noted that, as in fig. 1, the dashed line connection represents communication connection between units (the same understanding as that in the subsequent figures), and the arrangement positions of the units are only used for illustrating the connection relationship, and are not limited to the actual arrangement positions thereof.

Alternatively, the items to be stored may be placed in the storage compartment within the cabinet 12 after being individually tagged with the corresponding RFID tags. Each RFID tag uniquely corresponds to the article to which it is attached. When the cabinet door 14 is closed and not used by a user, the first antenna 16 may scan each RFID tag in the storage cavity and feed back a corresponding radio frequency signal to the RFID module 20 under the driving of the connected RFID module 20. The RFID module 20 may read the item information corresponding to each item according to the received radio frequency signal, and report the item information to the server, so that the server performs daily management work such as inventory. The article information includes, for example, article name, date of manufacture, article type, unit price, and place of manufacture. When a user uses the storage device 100, after receiving a door opening instruction, for example, a door opening instruction provided by the user through a mobile phone, a tablet computer, or a door opening button on the cabinet 12, the server may instruct the main control module 22 to unlock the cabinet door 14, so that the main control module 22 triggers the RFID module 20 to stop driving the first antenna 16 to work and record the article information of the latest inventory item. At which time the second antenna 18 is not yet activated.

The user can open the door 14 to grasp the contents of the storage chamber. When the user closes the cabinet door 14 after grasping enough of the desired object, the main control module 22 can trigger the RFID module 20 to start driving the second antenna 18. The second antenna 18 scans the RFID tags of the items to be settled taken out of the storage chamber by the user and feeds back corresponding radio frequency signals to the RFID module 20, so that the RFID module 20 obtains the item information of the items to be settled and reports the item information to the server through the main control module 22. The server can automatically complete the processes of settlement, deduction, bill issuing and the like according to the article information of each article waiting for settlement. After the cabinet door 14 is locked, the main control module 22 may trigger the RFID module 20 to start driving the first antenna 16 to work, so as to count the remaining inventory items; the second antenna 18 may trigger the RFID module 20 to stop driving the second antenna 18 to work when the main control module 22 receives a settlement success instruction issued after the server completes settlement, and waits for the next user to use.

In the storage device 100, the first antenna 16 and the second antenna 18 are respectively arranged inside and outside the cabinet body 12, the first antenna 16 uniformly scans the articles stored in the storage cavity, and the second antenna 18 uniformly scans the articles taken out of the storage cavity and waiting for settlement, so that the checking efficiency of the articles in the storage cavity is ensured, the scanning efficiency of the articles waiting for settlement is improved, and the automatic settlement and the checking efficiency of the storage are further improved. The articles waiting for calculation are not required to be manually scanned by a user, or the articles waiting for settlement are determined and scanned by the antenna in the cabinet body 12 in a complex identification mode, so that the problem that the article scanning and settlement efficiency of the traditional storage device is low is effectively solved, and the effect of greatly improving the scanning and settlement efficiency of the storage device 100 is achieved.

In one embodiment, the first antenna 16 may be periodically operated when the cabinet door 14 is closed (i.e., in the locked state). For example, by using the timing trigger function provided by the main control module 22, the triggering period of the RFID module 20 may be preset to the main control module 22, so that the RFID module 20 drives the first antenna 16 to periodically scan each article in the storage cavity in a preset period, thereby realizing that the main control module 22 periodically (for example, reporting once in 11 minutes: the main control module 22 works for 1 minute and waits for 10 minutes in 11 minutes) reports the article information of each article in the storage cavity to the server, and the first antenna 16 does not need to be in a working state for a long time when the cabinet door 14 is closed. The second antenna 18 may also automatically stop after a delay of a predetermined length of time after completing the scanning of the items to be settled. Therefore, energy consumption can be effectively reduced, and the data management efficiency of the server is improved.

In one embodiment, when the cabinet door 14 is turned from the open state to the closed state, for example, when the user finishes grasping the object and closes the cabinet door 14, so that the cabinet door 14 is locked, the first antenna 16 and the second antenna 18 may be activated to operate simultaneously, or may be activated after a predetermined time is delayed after the second antenna 18 is activated to operate. For example, after detecting that the cabinet door 14 is locked (e.g., receiving a locking signal fed back after the cabinet door 14 is locked), the main control module 22 may simultaneously output the trigger signal of the first antenna 16 and the trigger signal of the second antenna 18 to the RFID module 20, and simultaneously trigger the first antenna 16 and the second antenna 18 to start operation. For another example, after the main control module 22 detects that the cabinet door 14 is locked, the main control module outputs the trigger signal of the second antenna 18 to the RFID module 20 to trigger the second antenna 18 to start up, and after a preset time is delayed, the main control module outputs the trigger signal of the first antenna 16 to the RFID module 20 to trigger the first antenna 16 to start up. Thus, based on the conventional main control module 22, the working modes of the first antenna 16 and the second antenna 18 are flexibly set, and the inventory checking and settlement scanning efficiency is effectively improved through independent arrangement of the first antenna 16 and the second antenna 18 at different positions.

In one embodiment, the cabinet 12 is provided with a latch portion. The cabinet door 14 is provided with an electronic door lock. The electronic door lock is electrically connected with the main control module 22. The electronic door lock is matched with the locking part in structural position. It is understood that, in the above-described embodiment, the locking and unlocking of the cabinet door 14 can be realized by the cooperation between the locking portion provided on the cabinet door 14 and the electronic door lock provided on the cabinet body 12.

Alternatively, the electronic door lock may be disposed on the cabinet door 14, and correspondingly, the locking portion may be disposed on the cabinet body 12. The installation position of the electronic door lock on the cabinet door 14 can be determined according to the position of the locking portion provided on the cabinet body 12, and the electronic door lock can be installed on the cabinet door 14 by, but not limited to, screwing, gluing, welding, or the like. The electronic door lock may be, but is not limited to, an electromagnetic lock, a motor lock, or an electrically controlled manual lock. The locking portion may be a locking hole, a buckle, or a magnetic metal sheet, for example, a locking hole, a buckle, or a magnetic metal sheet fixed based on an electromagnetic attraction technology is provided on the cabinet body 12, as long as the locking portion and the electronic door lock can cooperate to complete the locking or unlocking of the cabinet door 14. Through the application of the electronic door lock, the characteristic that the electronic door lock can feed back corresponding electric signals when unlocking and locking is carried out can be utilized, so that the main control module 22 can effectively judge the opening and closing actions of the cabinet door 14, and the control of the RFID module 20 on the first antenna 16 or the second antenna 18 is accurately triggered.

In one embodiment, the cabinet is an electromagnetic shielding cabinet. The cabinet door 14 is an electromagnetic shielding glass door. It will be appreciated that the cabinet body 12 includes peripheral side wall panels. Each side wall plate can comprise two layers of electromagnetic shielding plates and a heat insulation layer sandwiched between the two layers of electromagnetic shielding plates. The cabinet door 14 is a shield door made of an electromagnetic shielding material. Preferably, the cabinet door 14 is an electromagnetic shielding glass door. In this way, the first antenna 16 disposed inside the cabinet 12 and the second antenna 18 disposed outside the cabinet 12 do not generate cross interference when scanning RFID tags, and accuracy of inventory scanning and settlement scanning is improved.

In one embodiment, the specific number of the first antennas 16 may be one, or may be two or more. The number of the first antennas 16 may be determined according to the specification and the internal structure of the cabinet 12 and the number of the types of stored articles, as long as the accurate and comprehensive scanning and identification of each article in the storage chamber can be ensured.

In one embodiment, the specific number of the second antennas 18 may be one, or may be two or more. The number of the second antennas 18 can be determined according to the type of the articles and the design requirement of the scanning distance, as long as the accurate and comprehensive scanning identification of each article waiting for settlement outside the storage cavity can be ensured.

In one embodiment, the first antenna 16 is disposed on an inner surface of a bottom panel of the cabinet 12, an inner surface of a side wall panel of the cabinet 12, or a cargo portion of the cabinet 12. It will be appreciated that the cabinet 12 is comprised of at least one, two or more side panels that are laterally oriented, and a floor that is adjacent to the floor, such as a chest freezer having a door 14 at the top, and the cabinet 12 is comprised of a floor and four side panels. The cabinet 12 may also be provided with a cargo portion therein for separating and/or carrying articles.

Optionally, the first antenna 16 may be disposed on an inner surface of the bottom plate (i.e., a surface facing the storage cavity), an inner surface of the sidewall plate, or in the object carrying portion, such as an inner portion or a surface of the object carrying portion: embedded in the loading portion or disposed on any surface of the loading portion, and the radiation direction of the first antenna 16 faces the direction of each object to be scanned. In this manner, reliable identification of each RFID tag within the storage compartment by the first antenna 16 may be ensured.

In one embodiment, the second antenna 18 is disposed on an outer surface of a side wall panel of the cabinet 12 or an outer surface of the cabinet door 14. It can be understood that, the cabinet body 12 and the cabinet door 14 both have the electromagnetic shielding structure, after the cabinet body 12 is closed by locking the cabinet door 14, the radio frequency signal inside the cabinet body 12 cannot penetrate through the cabinet body 12 or the cabinet door 14 to reach the outside of the cabinet body 12, and the radio frequency signal outside the cabinet body 12 cannot penetrate through the cabinet body 12 or the cabinet door 14 to reach the inside of the cabinet body 12. Therefore, the second antenna 18 may be disposed on the outer surface of any side wall plate of the cabinet body 12, or may be disposed on the outer surface of the cabinet door 14 (i.e., on the side away from the storage chamber), and the specific mounting position may be selected according to the effective scanning distance of the second antenna 18 and the convenience of scanning the article to be settled, so as to ensure that after the cabinet door 14 is locked, the second antenna 18 is quickly started to scan the information of the article to be settled, and the main control module 22 is convenient to report to the server.

Referring to fig. 2, in one embodiment, the RFID module 20 includes at least a first RFID reader 202 and a second RFID reader 204. The first RFID reader 202 and the second RFID reader 204 are respectively connected to the main control module 22 in a communication manner. The first RFID reader 202 is communicatively connected to the first antenna 16. Second RFID reader 204 is communicatively coupled to second antenna 18.

It is understood that in the above embodiments, the first antenna 16 and the second antenna 18 may be communicatively connected to the same RFID module 20, for example, the RFID module 20 is an RFID reader including at least two antenna ports. In this embodiment, optionally, the RFID module 20 at least includes two RFID readers, where the first antenna 16 is controlled by the first RFID reader 202, and the second antenna 18 is controlled by the second RFID reader 204. The first RFID reader-writer 202 and the second RFID reader-writer 204 may be both disposed on the cabinet 12, for example, may be disposed on the same PCB as the main control module 22, or disposed on a lateral sidewall plate, a top cover, or a bottom plate of the cabinet 12; or both can be arranged on the cabinet door 14; or one of the first RFID reader-writer 202 and the second RFID reader-writer 204 is disposed on the cabinet 12, and the other is disposed on the cabinet door 14, and the specific disposition position can be determined according to the first antenna 16, the second antenna 18, and the installation position of the main control module 22, as long as effective communication between each RFID reader-writer and the corresponding antenna and between the RFID reader-writer and the main control module 22 can be ensured, and the RFID reader-writers are prevented from being easily worn.

Through the communication connection between the first antenna 16 and the first RFID reader-writer 202 and the communication connection between the second antenna 18 and the second RFID reader-writer 204, the inventory item and the item waiting for settlement are scanned and identified through the special antenna and the RFID reader-writer respectively, and the reliability and the accuracy are higher.

In one embodiment, the first antenna 16 may be a dual-sided radiating antenna or a single-sided radiating antenna. It can be understood that the radiation direction of the first antenna 16 disposed in the cabinet 12 may be bidirectional or unidirectional, so that the RFID tags carried by the articles in the space areas on both sides of the radiation surface of the first antenna 16 can be effectively scanned, and the scanning efficiency of the first antenna 16 is maximized. For example, the first antenna 16 on the carrying part is a double-sided radiation antenna, so that the first antenna 16 on each carrying part can respectively emit radio frequency signals to two side space areas, and the coverage area of the radio frequency signals can be the RFID tag carried by the article in the space areas on two sides of the radiation surface of the first antenna 16. The first antenna 16 may also be a single-sided radiation antenna, so that the first antenna 16 may emit a radio frequency signal in one direction, thereby realizing radio frequency signal coverage of the RFID tag of each article, and reducing the overall cost of the storage device 100.

In one embodiment, the second antenna 18 may be a dual-sided radiating antenna or a single-sided radiating antenna. With a dual-sided radiating antenna, the scanning efficiency of the second antenna 18 for the items to be settled can be maximized. By adopting the single-sided radiation antenna, the cost of the whole storage device 100 is reduced while the accurate scanning of the articles waiting for settlement is considered.

In one embodiment, the first antenna 16 is a circularly polarized antenna or a linearly polarized antenna. The second antenna 18 is a circularly polarized antenna or a linearly polarized antenna. It is understood that the first antenna 16 and the second antenna 18 may be both circularly polarized antennas or both linearly polarized antennas. It is also possible that the first antenna 16 is a linearly polarized antenna and the second antenna 18 is a circularly polarized antenna.

The circularly polarized electromagnetic wave emitted by the circularly polarized antenna is a constant-amplitude rotating field and can induce the radio-frequency signals on the RFID tags in any polarization direction, so that the requirement on the placement direction of the articles is low, and the identification efficiency of the RFID tags of the articles waiting for calculation can be effectively improved by adopting the circularly polarized antenna. The linear polarization antenna has good directivity and low cost, and can be used by matching with the passive linear polarization RFID tag with lower cost, for example, when the linear polarization antenna is adopted, articles can be placed according to the polarization direction of the linear polarization antenna, so that the linear polarization direction of the RFID tag on the article is the same as the polarization direction of the linear polarization antenna. Therefore, by applying the circularly polarized antenna and/or the linearly polarized antenna, high identification efficiency can be realized, and the operation and maintenance cost of the storage device 100 can be effectively reduced.

In one embodiment, RFID module 20 comprises a single or multi-channel RFID module 20. It will be appreciated that the RFID module 20 described above may be a single channel RFID module 20 supporting a single antenna, such as a single antenna port RFID reader. In this way, the plurality of RFID modules 20 can drive the respective antennas, thereby identifying the article. RFID module 20 may also be a multi-channel RFID module 20, such as a multi-port RFID reader, that supports multiple antennas. Therefore, the plurality of antennas can be matched with one or two RFID modules 20 with a small number, namely, the identification of the articles can be realized, the identification efficiency is improved, and the operation and maintenance cost can be reduced.

Referring to fig. 3, in one embodiment, the storage device 100 further includes a display 24. The display 24 is disposed on the cabinet body 12 or the cabinet door 14. The display 24 is communicatively connected to the main control module 22. Alternatively, the display 24 may be a liquid crystal display 24 or a semiconductor light emitting display 24 as is conventional in the art, and may be used to display item information, advertising, or electronic codes (e.g., two-dimensional codes associated with store information or open and close door indication entry). Through the application of display 24, can show in real time that the article information that the article that second antenna 18 scanned, waited for the settlement corresponds, convenience of customers checks, can also show article information that the article that remains in the cabinet body 12 corresponds, convenience of customers looks over and snatchs, perhaps spot advertisement, is convenient for provide other product information or activity information for the user, improves the operation efficiency and the user experience of storing device 100.

In one embodiment, the display 24 includes a touch-sensitive display, a voice-controlled display, or a distance-sensitive display. Alternatively, the display 24 may be a touch-sensitive display as is conventional in the art, and the user may view the contents of the cabinet 12 or confirm payment, etc. on the display 24 by touch operation. The display 24 may also be a voice-activated display, and the user may interact with the display 24 by voice to complete item viewing, ordering, or order confirmation, etc. The display 24 may also be a distance sensing display, that is, the display 24 with a distance sensor, when the user approaches the storage device 100 and enters an effective range of distance sensing, the display 24 may automatically enter a working state from a standby state, insert an advertisement, or recommend item information corresponding to items in the cabinet 12. Through the application of the display 24 of the type, the use efficiency of the storage device 100 can be greatly improved, and the user experience is improved.

In one embodiment, the storage device 100 may further include a two-dimensional code tag. The two-dimensional code label is arranged outside the cabinet body 12 or the cabinet door 14. The two-dimensional code label is used for enabling the user terminal to obtain the operation information of the storage device 100 after being scanned by the user terminal.

It is understood that the two-dimensional code label can be, but is not limited to, a two-dimensional code label made of paper, plastic, paint film or metal film, or the like. Can be arranged on the outer surface of the cabinet body 12 or on the outer surface of the cabinet door 14, and the specific position can be arranged according to the user terminal which is easy to find and use by the user, such as code scanning and the like. The user terminal may be, but is not limited to, a mobile phone, a tablet computer, and other terminal devices. The operation information may be merchant information, door opening and closing information, or preferential activity information of a merchant to which the storage device 100 belongs, for example, after the user terminal scans the two-dimensional code, the display page may jump to a background service number of the merchant, that is, an online service platform that is opened in advance corresponding to the storage device 100, such as a wechat public number, a pay service number, a unionpay service number, or a service number of another platform. Therefore, the user can perform operations such as member registration, item selection, order placement or question feedback and the like on the user terminal.

Specifically, the user can scan the two-dimensional code tag through the user terminal to obtain the operation information of the storage device 100, so that the user terminal can perform operations such as unlocking or locking indication of the cabinet door 14, member registration, article browsing, shopping and payment, evaluation feedback, point management, article or store sharing, and the like. Through the setting of above-mentioned two-dimensional code label, can further improve storing device 100's availability factor, optimize user experience.

Referring to fig. 4, in an embodiment, a vending system 200 is further provided, which includes the server 30 and the storage device 100. The server 30 is connected to the main control module 22 of the storage device 100.

It is understood that the server 30 may communicate with the master module 22 through a network interface on the master module 22. When the cabinet door 14 is in the locked state, the main control module 22 triggers the RFID module 20 to drive the first antenna 16 to scan each article in the cabinet 12, and the server 30 may obtain article information corresponding to each article in the cabinet 12 in real time or periodically, so as to perform inventory data management. When the cabinet door 14 is turned from the open state to the closed state by the main control module 22, the RFID module 20 is triggered to drive the second antenna 18 to scan the articles to be settled outside the cabinet 12, and the server 30 can quickly and accurately obtain the article information corresponding to the articles to be settled, so as to complete settlement; and when the cabinet door 14 is restored to the locked state through the main control module 22, the RFID module 20 is triggered to drive the first antenna 16 to scan each article in the cabinet 12, and the server 30 can complete inventory and data update according to the latest article information, so as to maintain the accuracy of the article information corresponding to each article in the cabinet 12.

In the vending system 200, the first antenna 16 and the second antenna 18 are respectively arranged inside and outside the cabinet body 12 of the storage device 100, the first antenna 16 uniformly scans the articles stored in the storage cavity, and the second antenna 18 uniformly scans the articles taken out of the storage cavity and waiting for settlement, so that the checking efficiency of the articles in the storage cavity is ensured, the scanning efficiency of the articles waiting for settlement is improved, and the automatic settlement and the checking efficiency of the articles are further improved. The problem that the efficiency of scanning and settling the articles of the traditional storage device 100 is low is effectively solved, and the effect of greatly improving the efficiency of scanning and settling the articles of the storage device 100 is achieved.

In one embodiment, the server 30 comprises a cloud server or a physical server. The cloud server application is gradually popularized, the computing capacity is high, the use cost is low, and the operation and maintenance cost can be effectively controlled while background data management and quick settlement of the vending system 200 can be ensured through the application of the cloud server. The physical server is a traditional background local server, is early in application and mature and stable in technology, and can effectively meet background data management and rapid settlement of the storage device in a certain geographic range.
