Description

Technical Field

[0001] The present invention belongs to the field of smart lockers and relates to data analysis technology, in particular to an opening and closing control method, device, electronic equipment and medium for smart lockers. Background Art

[0002] Smart lockers are extremely safe, with solid structures and electromagnetic door locks. Smart lockers can only be opened by users with valid cards, which highly ensures the safety of users' property. In addition, when a single locker in a networked locker fails and cannot be used, it will not affect the use of other lockers.

[0003] The smart lockers in the prior art cannot monitor the status of items taken out of the lockers when the user takes out items. If the user forgets to close the door after taking out the items, it will affect the normal use of the locker. If the user fails to take out the items in time after opening the door but closes the door by mistake, it is necessary to contact the staff to open the locker, which is cumbersome and inefficient.

[0004] In view of the above technical problems, this application proposes a solution. Summary of the invention

[0005] The purpose of the present invention is to provide an opening and closing control method, device, electronic device and medium for a smart locker, which is used to solve the problem that the existing smart locker cannot monitor the state of the items taken out of the locker when the user takes out the items;

[0006] The technical problem to be solved by the present invention is: how to provide an opening and closing control method of an intelligent locker which can monitor the retrieval status of items in the locker when a user takes items out.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] An opening and closing control device for a smart locker includes a processor, wherein the processor is communicatively connected with an authentication module, a controller, a storage management module, a retrieval management module, an optimization management module, and a storage module;

[0009] The authentication module is used by the smart locker to authenticate the user;

[0010] The storage management module is used to collect item information from the locker after the locker completes the storage of items, and obtains the item data of the locker L1 seconds after the item storage is completed and the locker is closed. The item data includes storage weight data and item images. The storage weight data is the item weight value obtained by the weight sensor at the bottom of the locker, and the item image is an image obtained by taking an image of the storage space of the locker by a camera in the locker. The item data is sent to the processor, and the processor receives the item data, matches the item data with the locker, and sends it to the storage module for storage, and then cuts off the power supply line of the locker lighting through the controller;

[0011] The item retrieval management module is used to perform item retrieval status management analysis on the locker after the item is taken out of the locker: when the user takes out the item, the locker door is opened for L1 seconds to obtain the locker's open and closed status. If the locker state is open, a forget-to-close door analysis is performed; if the locker state is closed, an error-to-close door analysis is performed;

[0012] The optimization management module is used to perform optimization management analysis on the opening and closing control of the lockers.

[0013] As a preferred embodiment of the present invention, the specific process of authenticating the user includes: when the user uses the smart locker to store items, the identity information is first scanned through the authentication module, and after the identity information scan is completed, the priority sequence is retrieved through the storage module, and the empty locker ranked at the front in the priority sequence is marked as the control object, and the door of the control object is opened by the controller and the power supply line of the lighting of the control object is connected, and the opened control object is matched with the identity information; when the user needs to take out the items in the locker, the identity information is scanned again through the authentication module, and then the door of the locker corresponding to the identity information is opened by the controller and the power supply line of the locker lighting is connected.

[0014] As a preferred embodiment of the present invention, the specific process of forgetting to close the door analysis includes: obtaining the current load weight value of the locker through a weight sensor and marking it as load data CZ, capturing an image of the storage space of the locker through a camera and marking the captured image as an analysis image, retrieving an image of the locker when empty through a storage module and marking it as a comparison image, performing a grayscale comparison between the analysis image and the comparison image: enlarging the analysis image and the comparison image into pixel grid images and performing a grayscale transformation, overlapping the enlarged analysis image and the comparison image, marking the absolute value of the difference between the grayscale values ​​of the overlapping pixels in the analysis image and the comparison image as the deviation value of the pixel grid, summing and averaging the deviation values ​​of all the pixels in the analysis image to obtain the deviation data PL; obtaining the empty load coefficient KZ of the locker by numerically calculating the load data CZ and the deviation data PL; and determining whether the user's retrieval process is completed by the empty load coefficient KZ.

[0015] As a preferred embodiment of the present invention, the specific process of determining whether the user's picking-up process is completed by the no-load coefficient KZ includes: obtaining the no-load threshold KZmin through the storage module, and comparing the no-load coefficient KZ of the locker with the no-load threshold KZmin: if the no-load coefficient KZ is less than the no-load threshold KZmin, it is determined that the user has completed picking up the items and forgot to close the door, and a door closing signal is generated and sent to the processor. After receiving the door closing signal, the processor sends the door closing signal to the controller. After receiving the door closing signal, the controller controls the door of the corresponding locker to close, and at the same time cuts off the power supply line of the locker lighting; if the no-load coefficient KZ is greater than or equal to the no-load threshold KZmin, it is determined that the user has not completed picking up the items, and the open and closed state of the locker is obtained again after L1 seconds.

[0016] As a preferred embodiment of the present invention, the specific process of the wrong door closing analysis includes: obtaining the current load-bearing weight value of the locker through a weight sensor and marking it as the load-bearing value, marking the absolute value of the difference between the load-bearing value and the stored weight data as weight difference data ZC, capturing an image of the storage space of the locker through a camera and marking the captured image as a verification image, amplifying the verification image and the item image into a pixel grid image and performing a grayscale transformation, overlapping the amplified verification image with the item image, marking the absolute value of the difference between the grayscale values ​​of the overlapping pixels in the verification image and the item image as the pixel grid overlap value, summing and averaging the deviation values ​​of all the pixels in the verification image to obtain the overlap data CH; obtaining the retrieval coefficient QC by numerically calculating the weight difference data ZC and the overlap data CH; and determining whether the item should be taken out by the retrieval coefficient QC.

[0017] As a preferred embodiment of the present invention, the specific process of determining whether an item has been taken out by using a retrieval coefficient QC includes: obtaining a retrieval threshold QCmin through a storage module, and comparing the retrieval coefficient QC with the retrieval threshold QCmin: if the retrieval coefficient QC is less than the retrieval threshold QCmin, it is determined that the item has not been taken out and there is an accidental door closing phenomenon, the corresponding locker is marked as an accidental door closing object, a door opening signal is generated and sent to a processor, and the processor sends the door opening signal to a controller after receiving the door opening signal, and the controller opens the corresponding locker after receiving the door opening signal; if the retrieval coefficient QC is greater than or equal to the retrieval threshold QCmin, it is determined that the item has been taken out, a storage completion signal is generated and sent to the processor, and the processor cuts off the power supply line of the locker lighting through the controller after receiving the storage completion signal.

[0018] As a preferred embodiment of the present invention, the specific process of optimizing the management analysis of the opening and closing control of the lockers by the optimization management module includes: generating a management cycle, obtaining the number of times the locker is marked as an incorrectly closed object within the management cycle and marking it as the incorrectly closed value of the locker, arranging the lockers in order of the incorrectly closed values ​​from small to large to obtain a priority sequence, and sending the priority sequence to the storage module through the processor to update the priority sequence of the previous management cycle.

[0019] The opening and closing control method for a smart locker comprises the following steps:

[0020] Step 1: Authentication of the user: When the user uses the smart locker to store items, the user first scans the identity information through the authentication module. After the identity information scan is completed, the controller randomly opens a locker door and connects the power supply line of the locker lighting;

[0021] Step 2: After the locker completes the storage of items, the item information of the locker is collected, and the item data of the locker is obtained L1 seconds after the storage of items is completed and the locker is closed;

[0022] Step 3: After the locker is finished taking out the items, the locker is managed and analyzed for the status of the items taken out: when the user takes out the items, the locker door is opened for L1 second to obtain the locker's open and closed status, and the locker's open and closed status is used to perform analysis on whether the locker is forgotten to close or mistakenly closed;

[0023] Step 4: Optimize the management analysis of the locker opening and closing control: generate a management cycle, obtain the number of times the locker is marked as a mistakenly closed object within the management cycle and mark it as the mistaken closing value of the locker, arrange the lockers in order from small to large according to the mistaken closing value to obtain a priority sequence, and send the priority sequence to the storage module through the processor for storage.

[0024] The invention discloses an electronic device for controlling the opening and closing of a smart locker, comprising a weight sensor, a camera and a lighting lamp inside the locker, wherein the weight sensor, the camera and the lighting lamp are all electrically connected to a controller through wires.

[0025] An electronic medium for opening and closing control of a smart locker stores a computer program, which implements an opening and closing control method for a smart locker when executed by a processor.

[0026] The present invention has the following beneficial effects:

[0027] 1. The user's identity can be authenticated through the authentication module. The user's identity information can be collected when depositing items. Then, when taking items out, the cabinet can be automatically opened for the user through identity information comparison, ensuring the storage security of items while improving the efficiency of storing and taking out items;

[0028] 2. The storage management module can collect information about items in the locker after the items are stored. After the items are stored, their weight and images are collected and stored to provide data support for wrong door closing analysis;

[0029] 3. Through the forget-to-close door analysis process, the phenomenon of forgetting to close the door after taking out items is detected. When it is detected that the items are taken out but the door is not closed, the controller will automatically close the door to avoid the forgetting to close the door affecting the subsequent use of the locker;

[0030] 4. Through the wrong door closing analysis process, the wrong door closing phenomenon during the retrieval process is detected. By comparing and analyzing the storage feature data of the locker and the item data, it is determined whether the items are taken out when the door is closed. If the door is closed due to an erroneous operation but the items have not been taken out, the controller will automatically open the door to improve the processing efficiency when the door is closed by mistake;

[0031] 5. Through the optimization management module, the locker opening and closing control can be optimized and analyzed. The lockers are prioritized according to the number of times they are marked as mistakenly closed objects during the management cycle to obtain a priority sequence, thereby reducing the probability of mistaken closing in the next management cycle.

[0035] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1

[0037] like Figure 1 As shown, an opening and closing control device for a smart locker includes a processor, and the processor is communicatively connected to an authentication module, a controller, a storage management module, a retrieval management module, an optimization management module, and a storage module.

[0038] The authentication module is used for smart lockers to authenticate users: when users use smart lockers to store items, they first scan their identity information through the authentication module. After the identity information scan is completed, the storage module retrieves the priority sequence, marks the empty locker ranked first in the priority sequence as the control object, opens the door of the control object through the controller and connects the power supply line of the control object's lighting, and matches the opened control object with the identity information; when the user needs to take out items from the locker, the authentication module scans the identity information again, and then opens the door of the locker corresponding to the identity information through the controller and connects the power supply line of the locker's lighting; authenticate the user, collect the user's identity information when storing items, and then automatically open the locker for the user through identity information comparison when taking items, thereby ensuring the security of item storage while improving the efficiency of item storage and retrieval.

[0039] The storage management module is used to collect item information from the locker after the locker completes item storage, and obtain the item data of the locker L1 second after the item storage is completed and the locker is closed. The item data includes storage weight data and item image. The storage weight data is the item weight value obtained by the weight sensor at the bottom of the locker, and the item image is an image obtained by photographing the storage space of the locker through the camera in the locker. The item data is sent to the processor, and the processor receives the item data, matches the item data with the locker and sends it to the storage module for storage, and then cuts off the power supply line of the locker lighting through the controller; after the locker completes item storage, the locker item information is collected, and the weight and image are collected and stored after the item storage is completed, providing data support for the wrong door closing analysis.

[0040] The item retrieval management module is used to manage and analyze the retrieval status of the locker after the item is taken out of the locker: when the user takes the item, the locker door is opened for L1 second to obtain the locker's open and closed status. If the locker is open, a forget-to-close analysis is performed; if the locker is closed, an error-to-close analysis is performed.

[0041] The specific process of forgetting to close the door analysis includes: obtaining the current load weight value of the items in the locker through the weight sensor and marking it as load data CZ, capturing images of the storage space of the locker through the camera and marking the captured images as analysis images, retrieving images of the locker when empty through the storage module and marking them as comparison images, performing grayscale comparison between the analysis image and the comparison image: enlarging the analysis image and the comparison image into pixel grid images and performing grayscale transformation, overlapping the enlarged analysis image and the comparison image, marking the absolute value of the difference between the grayscale values ​​of the overlapping pixels in the analysis image and the comparison image as the deviation value of the pixel grid, summing and averaging the deviation values ​​of all the pixels in the analysis image to obtain the deviation data PL; obtaining the empty load coefficient KZ of the locker through the formula KZ=α1*CZ+α2*PL, where α1 and α2 are both proportional coefficients, and α1>α2>1; The no-load threshold KZmin is obtained through the storage module, and the no-load coefficient KZ of the locker is compared with the no-load threshold KZmin: if the no-load coefficient KZ is less than the no-load threshold KZmin, it is determined that the user has completed taking the items and forgot to close the door, and a door closing signal is generated and sent to the processor. After receiving the door closing signal, the processor sends the door closing signal to the controller. After receiving the door closing signal, the controller controls the door of the corresponding locker to close and cuts off the power supply line of the locker lighting; if the no-load coefficient KZ is greater than or equal to the no-load threshold KZmin, it is determined that the user has not completed taking the items, and the open and closed state of the locker is obtained again after L1 seconds; the forgetting to close the door phenomenon after taking the items is detected through the forgetting to close the door analysis process. When it is detected that the items are taken out but the door is not closed, the controller automatically closes the door to avoid the forgetting to close the door phenomenon affecting the subsequent use of the locker.

[0042] The specific process of the wrong door closing analysis includes: obtaining the current load-bearing weight value of the items in the locker through the weight sensor and marking it as the load-bearing value, marking the absolute value of the difference between the load-bearing value and the stored weight data as the weight difference data ZC, taking an image of the storage space of the locker through the camera and marking the captured image as the verification image, amplifying the verification image and the item image into a pixel grid image and performing grayscale transformation, overlapping the amplified verification image with the item image, marking the absolute value of the difference between the grayscale values ​​of the overlapping pixels in the verification image and the item image as the pixel grid overlap value, summing and averaging the deviation values ​​of all the pixels in the verification image to obtain the overlap data CH; obtaining the extraction coefficient QC through the formula QC=β1*ZC+β2*CH, where β1 and β2 are both proportional coefficients, and β1>β2>1; obtaining the extraction threshold QCmin through the storage module, and comparing the extraction coefficient QC with the extraction threshold QCmin :If the retrieval coefficient QC is less than the retrieval threshold QCmin, it is determined that the item has not been taken out and there is an accidental door closing phenomenon. The corresponding locker is marked as an accidental door closing object, and a door opening signal is generated and sent to the processor. After the processor receives the door opening signal, it sends the door opening signal to the controller. After the controller receives the door opening signal, it opens the corresponding locker; if the retrieval coefficient QC is greater than or equal to the retrieval threshold QCmin, it is determined that the item is taken out, and a storage completion signal is generated and sent to the processor. After the processor receives the storage completion signal, the controller cuts off the power supply line of the locker lighting through the controller; the accidental door closing phenomenon in the retrieval process is detected through the accidental door closing analysis process, and the storage feature data of the locker is compared and analyzed with the item data to determine whether the item is taken out when the door is closed. If the door is closed due to an erroneous operation but the item has not been taken out, the controller automatically opens the door to improve the processing efficiency when the door is closed by mistake.

[0043] The optimization management module is used to perform optimization management analysis on the opening and closing control of the lockers: generate a management cycle, obtain the number of times the lockers are marked as mistakenly closed objects within the management cycle and mark them as the mistaken closing values ​​of the lockers, arrange the lockers in order from small to large according to the mistaken closing values ​​to obtain a priority sequence, and send the priority sequence to the storage module through the processor to update the priority sequence of the previous management cycle; perform optimization management analysis on the opening and closing control of the lockers, prioritize the lockers according to the number of times they are marked as mistakenly closed objects within the management cycle to obtain a priority sequence, and reduce the probability of mistaken closing in the next management cycle.

[0044] Embodiment 2

[0045] like Figure 2 As shown, the opening and closing control method for the smart locker includes the following steps:

[0046] Step 1: Authentication of the user: When the user uses the smart locker to store items, the user first scans the identity information through the authentication module. After the identity information scan is completed, the controller randomly opens a locker door and connects the power supply line of the locker lighting;

[0047] Step 2: After the locker completes the storage of items, the item information of the locker is collected, and the item data of the locker is obtained L1 seconds after the storage of items is completed and the locker is closed;

[0048] Step 3: After the locker is finished taking out the items, the locker is managed and analyzed for the status of the items taken out: when the user takes out the items, the locker door is opened for L1 second to obtain the locker's open and closed status, and the locker's open and closed status is used to perform analysis on whether the locker is forgotten to close or mistakenly closed;

[0049] Step 4: Optimize the management analysis of the locker opening and closing control: generate a management cycle, obtain the number of times the locker is marked as a mistakenly closed object within the management cycle and mark it as the mistaken closing value of the locker, arrange the lockers in order from small to large according to the mistaken closing value to obtain a priority sequence, and send the priority sequence to the storage module through the processor for storage.

[0050] The invention discloses an opening and closing control method, device, electronic device and medium for smart lockers. When the user uses the smart locker to store items, the authentication module is used to scan the identity information first. After the identity information scan is completed, the controller randomly opens the door of a locker and connects the power supply line of the locker lighting lamp; after the locker completes the storage of items, the locker collects item information, and obtains the item data of the locker L1 second after the storage of items is completed and the locker is closed; when the user takes out items, the locker's opening and closing state is obtained L1 second after the door is opened, and the door forgetting or wrong door closing analysis is performed based on the locker's opening and closing state; a management cycle is generated, the number of times the locker is marked as a wrongly closed object within the management cycle is obtained and marked as the wrong closing value of the locker, the lockers are arranged in order from small to large according to the wrong closing value to obtain a priority sequence, and the priority sequence is sent to the storage module through the processor for storage.

As long as they do not deviate from the structure of the invention or exceed the scope defined by the claims, they should all fall within the protection scope of the present invention.

[0052] The above formulas are obtained by collecting a large amount of data for software simulation and selecting a formula close to the actual value. The coefficients in the formula are set by technicians in this field according to actual conditions; for example: formula KZ=α1*CZ+α2*PL; technicians in this field collect multiple groups of sample data and set corresponding no-load coefficients for each group of sample data; substitute the set no-load coefficients and the collected sample data into the formula, any two formulas constitute a set of two-variable linear equations, screen the calculated coefficients and take the average, and obtain the values ​​of α1 and α2 as 2.25 and 1.87 respectively;

[0053] The size of the coefficient is to quantify each parameter to obtain a specific value for subsequent comparison. The size of the coefficient depends on the amount of sample data and the technical personnel in this field initially setting the corresponding no-load coefficient for each set of sample data; as long as it does not affect the proportional relationship between the parameter and the quantized value, such as the no-load coefficient is proportional to the value of the load data.
