Therefore, "how to automatically record standard mold accessory information using video surveillance equipment and a weighing module" is the technical problem to be solved by the present invention. Summary of the Invention

[0004] The purpose of the present invention is to provide a management method and system for standard mold accessory information to solve the problem of "how to automatically record standard mold accessory information using video surveillance equipment and a weighing module" proposed in the above background art.

If so, update the material requisition book. If not, integrate the material requisition book and the call request to generate verification information and push the verification information to the preset terminal.

[0022] Further, the step of obtaining adjacent snapshot sets and comparing to find out the different items includes:

[0023] Calculate the pixel ratio of the different items in the adjacent snapshot sets, convert it into the actual area, and deduce the change amount of the standard mold parts.

[0049] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0050] In Embodiment 1, Figure 1 The implementation process of the management method for standard mold accessory information provided by an embodiment of the present invention is shown, and the details are as follows:

[0051] S100: Collect the inventory data of standard mold accessories, locate the storage locations, determine the accessory types of each of the storage locations, obtain the attributes of the standard mold accessories, where the attributes at least include: name and single weight, select the deployment locations of video monitoring devices, collect the video monitoring data including all storage locations, and trigger the activation of the weighing module pre - integrated at the storage locations when detecting human motion features.

[0052] Use barcodes, RFID, or manual inventory counting methods to scan and input the inventory data of all standard mold parts. Standard mold parts include: guiding elements (such as guide pillars, guide bushes), positioning elements (such as locating rings, locating pins), elastic elements (such as springs, nitrogen springs), and fixing parts (such as screws, nuts), etc. Inventory data includes: inventory quantity, storage location, and equipment number, etc. The storage location is generally a shelf or a storage box, etc.; classify each storage location to clarify the specific type of parts stored in it. The part type is also the type of standard mold parts; for example, divide the storage location into multiple areas such as A and B. Area A is used to store springs, and Area B is used to store screws.

[0053] Determine the attributes of each standard mold part from public data, standard mold part suppliers, or through actual measurement. The attributes at least include name, size, and single weight, etc.; deploy video surveillance equipment at the storage location. One video surveillance equipment can be used to monitor all standard mold parts, or a corresponding video surveillance equipment can be configured for each standard mold part. The video surveillance equipment is a high-definition camera or an AI intelligent monitoring system; use the video surveillance equipment to collect video surveillance data of standard mold parts containing all part types, and combine computer vision and human motion detection algorithms to analyze the monitoring screen. When human motion features such as a person approaching, picking up or placing items are detected in the storage area, trigger the weighing module deployed at the storage location.

[0054] For example, there are currently three standard mold parts: locating pins, springs, and screws. Each standard mold part is stored in a storage box with dimensions of 800×600×300mm and is neatly arranged on the shelf. A high-definition camera is installed on the shelf, which can identify, detect, and monitor the locating pins, springs, and screws. A weighing module is also installed under each storage box, which can accurately record the weight of each storage box.

[0055] S200: Collect the total weight of each storage location via the weighing module. When the total weight changes, calculate the change value of the total weight to obtain the changed item, record the change time, and read out the storage location where the total weight has changed to obtain the changed location.

[0056] After the weighing module is started, record the total weight of each standard mold part and compare it with the previous total weight to determine whether the total weight has changed. If so, define the difference between the two as the changed item; record the change time of the total weight and determine the storage location where the total weight has changed as the changed location.

[0057] Continuing with the above example for detailed description, when the total weight of the storage box corresponding to the spring changes, the changed item is the specific change value of the total weight of the spring, and the changed location is Area A.

[0058] S300: From the video surveillance data, extract snapshots at the changed position and before and after the changed time to obtain a set of adjacent snapshots, compare the distinguishing items, and determine whether the changed items and the distinguishing items are the same based on the attributes. If so, update the inventory data, identify the portrait data from the adjacent snapshot set, integrate the portrait data, inventory data and changed items, generate a material requisition book, and send it to a preset terminal. If not, play a preset reminder voice.

[0059] From the video surveillance data, the image data at the corresponding changed position is extracted, and snapshots before and after the change time are captured to generate a set of adjacent snapshots. The adjacent snapshot sets are compared and analyzed using a computer vision algorithm to determine the changed part, namely the distinguishing item, where the distinguishing item is the number of newly added or reduced standard mold accessories. The distinguishing item and the changed item are compared, and based on the attribute conversion, it is determined whether the two are the same. If they are the same, the inventory data is updated, and the image data of the person at the changed position is extracted from the adjacent snapshot set using portrait recognition technology, and the recognized portrait data, inventory data and changed items are integrated to generate a material requisition book. In other words, the material requisition book records the information of the person who takes or returns the material, the number of standard mold accessories taken and placed, the storage location, the weight change value and the change time, etc. If the change item and the distinguishing item are different, a preset reminder voice is played to prompt the person who is taking and placing the standard mold accessories to review, where the reminder voice can be: "The number of accessories is incorrect, please check."

[0060] In Example 2, Figure 2 The implementation process of the management method of standard mold parts information provided by an embodiment of the present invention is shown. The steps of collecting the inventory data of standard mold parts, locating the storage location, determining the type of parts at each storage location, and obtaining the properties of the standard mold parts are described in detail as follows:

[0061] S101: extracting a snapshot after a change time from the video surveillance data to obtain an inventory status snapshot, and configuring a one-to-one correspondence between the inventory status snapshot and a storage location.

[0062] From the video surveillance data, a snapshot after the change time is captured and defined as an inventory status snapshot, where the inventory status snapshot reflects the storage quantity and placement status of standard mold accessories at the current moment; each storage location corresponds to an inventory status snapshot; the advantage of this is that it can assist management personnel in understanding the storage status of standard mold accessories in real time, ensure the consistency of inventory data with the actual physical status, and automatically realize the inventory and safety monitoring of standard mold accessories.

[0063] S102: Label the inventory data and attributes in the inventory status snapshot to generate an actual view, and send the actual view to a preset terminal.

[0064] Integrate data for each storage location, match the attributes of the accessories (such as name, specification, quantity, and single weight, etc.) with their positions in the snapshot, and label them in the inventory status snapshot to generate an actual view; the actual view shows data such as the quantity, weight, storage location, and single weight of each standard die accessory currently. Send the actual view to a preset terminal, where the preset terminal is the terminal of the standard die accessory management personnel.

[0065] In Embodiment 3, Figure 2 Shows the implementation process of the management method for standard die accessory information provided by the embodiments of the present invention. The following details the step of collecting video surveillance data including all storage locations and triggering the activation of the weighing module pre-integrated at the storage location when detecting human motion characteristics, as follows:

[0066] S103: Extract behavior features from the video surveillance data, compare with a pre-constructed feature set, and determine whether there are identical items. The feature set at least includes: human motion features and action features. If so, activate the weighing module and record the activation time. If not, activate a preset sleep strategy.

[0067] In the video surveillance system, by using computer vision and deep learning technologies, extract behavior features from the real-time collected video surveillance data. The behavior features include: the movement trajectory of personnel, action patterns, and the behavior of picking up and placing items, etc. If the behavior features are identical to the feature set, activate the weighing module and record the activation time. If not, activate the sleep strategy, where the sleep strategy is to weigh each storage location at a predetermined frequency; in other words, the weighing module is only activated when detecting specific behavior features (such as picking up), and when detecting other behavior features (such as personnel cleaning the shelves), the weighing module will not be activated.

[0068] In Embodiment 4, Figure 3 Shows the implementation process of the management method for standard die accessory information provided by the embodiments of the present invention. The following details the step of collecting the total weight of each storage location via the weighing module and calculating the change value of the total weight when the total weight changes, as follows:

[0069] S201: Collect the total weight at the activation time to obtain the historical weight. When the total weight changes, define the weight at the change time as the current weight.

[0070] Determine the total weight before picking up and placing the standard mold parts as the historical weight, and determine the weight after picking up and placing the standard mold parts as the current weight.

[0071] S202: Calculate the difference between the historical weight and the current weight to obtain a change value. When the change value is greater than the threshold, trigger a pre-constructed manual review mechanism.

[0072] Determine the difference between the historical weight and the current weight as the change value. If the change value is greater than the threshold, it indicates that the standard mold parts may be lost. At this time, start the manual review mechanism, where the manual review mechanism is: conduct a manual review by the standard mold parts management personnel.

[0073] In Embodiment 5, Figure 4 The implementation process of the management method for standard mold parts information provided by the embodiments of the present invention is shown. The following details the steps of obtaining adjacent snapshot sets and comparing different items, as follows:

[0074] S301: Calculate the pixel ratio of the different item in the adjacent snapshot sets and convert it into the actual area to estimate the change amount of the standard mold parts.

[0075] Compare the areas that change between the snapshots. Using image processing technology, calculate the pixel ratio of the different item in the adjacent snapshot sets, that is, the pixel ratio of the different item in the entire snapshot image; according to the known ratio in the physical environment or the conversion relationship between pixels and actual dimensions, determine the actual area of the different item, and estimate the change amount of the standard mold parts based on the size and shape of a single standard mold part, etc.

[0076] S302: Determine whether there are abnormal features in the behavior features. If so, generate an alarm message and send the alarm message to a preset terminal.

[0077] By using computer vision and deep learning technologies, determine whether there are abnormal features in the real-time collected video surveillance data. The abnormal features include: picking up the wrong parts or staying for a long time without picking up, etc. Generate an alarm message and send the alarm message to a preset terminal; the alarm message includes the detailed description of the abnormal behavior, the occurrence time, the location, and the possible risks, etc.

[0078] In Embodiment 6, different from Embodiment 1, in the embodiments of the present invention, the method further includes:

[0079] Build an inventory management platform for standard mold parts, receive the call requests uploaded by users, and obtain the review results;

[0080] When the audit result is passed, extract the portrait features of the user from the video surveillance data, compare with the preset face recognition library, and determine whether the material requisition book is the same as the call request. If so, update the material requisition book. If not, integrate the material requisition book and the call request to generate verification information and push the verification information to the preset terminal.

[0081] Create an inventory management platform. The inventory management platform is a digital system that can manage and optimize inventory. When taking standard mold parts, the user uploads a call request to the inventory management platform. The call request should include: the quantity and type of standard mold parts to be used, etc. After the standard mold part manager reviews, the review result is sent to the user.

[0082] If the audit is passed, extract the portrait features from the video surveillance data, use face recognition technology to compare with the preset face recognition library to confirm the user's identity. If the face recognition is passed and the quantity and type of the standard mold parts taken by the user are the same as the call request, update the material requisition book. Otherwise, if they are different, integrate the call request, the changed items and the different items to generate verification information and send the verification information to the preset terminal, where the preset terminal is the standard mold part manager's terminal.

[0083] In Embodiment 7, different from Embodiment 1, in the embodiment of the present invention, the method further includes:

[0084] Establish a mapping between the storage location and the set value. When the total weight is less than the set value, generate a replenishment reminder and set the sending time.

[0085] Take time as the abscissa and the total weight at the corresponding time as the ordinate to draw a change trend graph and adjust the sending time.

[0086] Establish a mapping relationship between the storage location and the set value, and set a minimum inventory threshold, that is, the set value, for each storage location. When it is monitored by the weighing module or the video surveillance device that the total weight of a certain storage location is lower than the set value, generate a replenishment reminder and send the replenishment reminder to the standard mold part manager's terminal. It should be noted that the set value is not zero. By analyzing the change trend graph, the time when the inventory may be emptied can be found, and the sending time can be adjusted according to this time, so as to intuitively display the law and fluctuation of inventory changes, and adjust the replenishment strategy and cycle.

[0087] For example, the inventory data of the spring in the standard mold fittings reaches the set value on the 14th. By analyzing the trend chart of the changes, it is found that the spring may run out on the 17th or 18th. At this time, the sending time is from the 15th to the 17th; in this embodiment, the sending time is not limited, and the specific sending time can be determined by the management personnel of the standard mold fittings.
