Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration specific embodiments of the application. In the drawings, like reference numerals describe substantially similar components throughout the different views. Various specific embodiments of the application are described in sufficient detail below to enable those skilled in the art to practice the teachings of the application. It is to be understood that other embodiments may be utilized or structural, logical, or electrical changes may be made to embodiments of the present application.

The existing intelligent container takes the inventory quantity checked before a user opens a cabinet door as the inventory quantity before the user takes the commodity. When the user is detected to close the cabinet door, checking the commodity in the intelligent container again through the RFID antenna, and taking the obtained stock quantity as the stock quantity after the user takes the commodity. An order for the user is created by the difference in inventory before and after the user picks up the merchandise.

The existing intelligent container generally judges whether the cabinet door is closed or not by detecting whether a lock tongue of a door lock of the cabinet door is in place or not. For example, whether the lock tongue reaches a predetermined position is detected by a lock state detector installed at a door lock of the cabinet door or a corresponding position of the cabinet door. As will be appreciated by those skilled in the art, the lock state detector may have other detection modes, and will not be described in detail herein.

However, if the lock tongue is blocked when the user closes the door, the lock state detector cannot detect that the lock tongue is in place, then the intelligent container can consider that the cabinet door is not related, and the RFID antenna cannot be triggered to check again, so that an order cannot be generated. This may result in a situation where multiple shopping orders are settled on one person. Or an lawless person may damage the lock state detector, causing loss of merchandise in the cabinet.

The application provides a new processing mode. The closing condition of the cabinet door of the container is judged by combining a plurality of modes, and corresponding subsequent processing is carried out according to the closing condition, so that the accuracy of generating orders by the intelligent container is improved, the shopping environment of unmanned vending is improved, and the benefits of consumers are ensured. According to one embodiment of the application, the various ways may include a lock state detector, a door state detector, or a video device, among others.

According to one embodiment of the application, the intelligent containers 302-304 can create orders using their own processors and send the created orders to a server, which sends them to the user. Or the intelligent containers 302-304 control the operation of the container according to the instructions of the server and send inventory amounts to the server, which generates orders and sends them to the user. Further, the intelligent cabinet may also transmit the detection results of the lock state detector and the door state detector to the server.

FIG. 4 is a flow chart of a method for preventing false slips according to one embodiment of the present application. As shown in the figure, the stock quantity in the intelligent container is A before a user opens the cabinet door to take the commodity. As will be appreciated by those skilled in the art, the inventory a may be obtained by identifying the RFID tag of the commodity in the container using the RFID antenna in the smart container, may be preset, or may be obtained from a server.

In step 401, a cabinet door of the intelligent cabinet is opened. In general, the shopping flow starts with the user opening the cabinet door of the intelligent container. For example, a user scans a two-dimensional code on an intelligent container using a mobile terminal. After receiving the request of the user, the server confirms the identity of the user and allows the user to use the intelligent container, and then sends an instruction to the intelligent container to unlock the door lock of the intelligent container. After the door lock of the intelligent container is opened, a user can open the door of the intelligent container. It will be appreciated by those skilled in the art that the above is merely one way to open the intelligent container door. The cabinet door of the intelligent container can be opened by scanning the two-dimension code on the mobile terminal of the user, scanning the fingerprint of the user, scanning the palm print of the user, scanning the iris of the user or directly logging in the mobile terminal of the user.

In step 402, a door status detector and a lock status detector of the container detect a status condition of a container door and a status condition of a container door lock, respectively. When the cabinet door of the intelligent container is opened, the door state detected by the door state detector is opened, and the lock state detected by the lock state detector is unlocked.

In step 403, the processor or the system server of the container determines whether the container door is normally closed according to the detected door status and door lock status.

According to one embodiment of the present application, if the door state detected by the door state detector is closed and the lock state detected by the lock state detector is locked, it indicates that the door is normally closed, and the process proceeds to step 404. If the door state detected by the door state detector is closed and the lock state detected by the lock state detector is unlocked, or if the door state detected by the door state detector is open and the lock state detected by the lock state detector is locked, this indicates that an abnormal closing condition of the cabinet door has occurred, and the process goes to step 405.

In step 404, the RFID of the commodity in the cabinet is checked by using the RFID antenna in the cabinet, so as to obtain the stock B after the user takes the commodity. The user order may be generated based on the difference between the inventory a before the user picks up the merchandise and the inventory B after the user picks up the merchandise.

In step 405, when the result of step 403 is that the cabinet door is closed abnormally, the user is prompted to re-close the cabinet door or lock the cabinet door by using the second lock, etc., to perform a post-processing procedure of cabinet door closing abnormality. Then, step 402 may be returned.

Fig. 5 is a flowchart of a cabinet door closing abnormality post-processing procedure according to an embodiment of the present application. As shown in the figure, in step 501, when the result of the judgment is that the cabinet door is closed abnormally, the user is reminded of the cabinet door being closed abnormally, and the user can be further reminded of performing simple operation on the cabinet door, for example: closing the cabinet door again; or cleaning sundries on the door lock of the cabinet door, and closing the cabinet door again. According to one embodiment of the application, the means for alerting the user includes, but is not limited to: the voice reminding of the container voice equipment is utilized, the lamplight equipment on the container is utilized to carry out lamplight reminding, the display screen on the container is utilized to remind, and the reminding or the combination of one or more of the above is sent to the mobile terminal of the user.

When the user simply operates the cabinet door, the operations of steps 502 to 504 are substantially the same as steps 402 to 404 in the method shown in fig. 4, and thus will not be described again. When the result of the judgment in the step 503 is that the container is closed abnormally, the step 501 is returned again to remind the user of the cabinet door closing abnormally.

The above steps are based on the fact that the user can repeatedly operate the cabinet door of the container. The method can solve the small faults of blocking and the like of the door lock of the cabinet door. If it is not, the following steps are continued.

In step 505, when the number of times of detecting the abnormal closing of the cabinet door is greater than the preset operation number threshold value X, it can be considered that the failure of the cabinet door is serious, and the failure of the cabinet door of the intelligent container is notified if the failure cannot be solved by simply and repeatedly closing or cleaning sundries. According to one embodiment of the application, the occurrence of a cabinet door failure of the intelligent cabinet may inform the cabinet operator, server, shopping user, store clerk, etc., or one or more of the above.

As understood by those skilled in the art, the threshold value X for the preset number of operations may be set based on statistics during consumption. According to one embodiment of the application, the threshold value X may be 2 to 4 times, in particular 3 times. Of course, according to different application experiences, the store owner of the unmanned vending shop can also adjust the threshold value of the operation times according to the own requirements.

According to other embodiments, the following steps may also be continued. In step 506, if a second lock is present in the intelligent container, the second lock is activated, locking the door. For example, the second lock may be an electromagnetic lock. When the cabinet door is closed abnormally and cannot be solved through simple operation, the electromagnetic lock is started. The electromagnetic lock strongly adsorbs the counter door to close the counter door. As will be appreciated by those skilled in the art, the electromagnet device is only one embodiment of the present application, and other embodiments already known in the art may be applied to the present application. For example: the cabinet door can be connected by a swinging cylinder or a hydraulic cylinder, the cabinet door is locked by a starting cylinder or a hydraulic cylinder, or the cabinet door is connected by other linkage mechanisms, and the cabinet door is closed by the action of the linkage mechanisms, such as: rack and pinion, crank block, ball screw, etc. According to one embodiment of the application, the smart container may comprise one or more second locks.

If the second lock locks the door, step 507, the process goes to step 504 to generate the user order. According to one embodiment of the application, the use of the intelligent cabinet is stopped and a prompt is given to the user before the door lock of the cabinet door is not repaired. Or the second lockset can be used for realizing the use of the intelligent container.

In step 508, if the intelligent container does not have the second lock, the user is prompted to replace the commodity with the intelligent container when the door is not closed and cannot be resolved by simple operation. And stopping the use of the intelligent container and prompting a user before the door lock of the cabinet door is not maintained.

In step 509, according to one embodiment of the application, the camera device of the intelligent container is started to capture an image of the surroundings of the intelligent container. Further, a corresponding prompt is made on the intelligent container.

Although the proposal disclosed by the application can possibly prolong the generation time of the shopping orders of the user to a certain extent and can also need the user to simply process the container, the situation that the cabinet door of the container is closed is detected by a plurality of detection units, so that the false orders caused by mechanical faults can be effectively prevented. And the post-processing step of abnormal cabinet door closing can greatly improve the accuracy of order generation and avoid unnecessary economic loss to users.

The above embodiments are provided for illustrating the present invention and not for limiting the present invention, and various changes and modifications may be made by one skilled in the relevant art without departing from the scope of the present invention, therefore, all equivalent technical solutions shall fall within the scope of the present disclosure.
