Description

Technical Field

[0001] This invention relates to the field of unmanned consumables warehouse management technology, specifically a warehouse management system applied to unmanned consumables warehouses. Background Technology

[0002] With the rapid development of intelligent manufacturing and lean supply chain management, unmanned warehouses have become an important carrier for the management of MRO materials, spare parts and various consumables in the industrial field. Especially in scenarios that require 24-hour operation, high-frequency use and storage of multiple categories, the application of unmanned consumable warehouses is becoming more and more widespread.

[0003] In terms of specific management, existing unmanned consumable warehouses still face many pain points:

[0004] The prioritization of pickups lacks a scientific basis, relying solely on the urgency of pickup needs without considering core data such as pickup cycle and consumable utilization efficiency. This leads to pickup chaos and unreasonable resource allocation when inventory is insufficient. During the supply process, inventory backlog issues are difficult to identify in a timely manner, resulting in some consumables being stored for extended periods until they expire or become damaged, causing resource waste. Furthermore, the lack of accuracy in outbound matching makes it easy for pickup terminals to engage in unauthorized pickups.

[0005] Furthermore, the priority of picking up goods cannot be linked to the allocation of supply resources, which reduces the targeting and priority control of supply.

[0006] The lack of effective safety coordination between replenishment and retrieval processes makes it easy for replenishment equipment and retrieval terminals to conflict paths, posing safety hazards. During the storage of consumables, issues such as damaged boxes and abnormal placement cannot be monitored in real time, resulting in a high consumable loss rate.

[0007] Furthermore, the inability to link safety coordination with consumable storage between replenishment and retrieval reduces warehouse management efficiency.

[0008] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0009] The purpose of this invention is to solve the problems mentioned above by proposing a warehouse management system for unmanned consumable warehouses.

[0010] The objective of this invention can be achieved through the following technical solutions:

[0011] A warehouse management system for unmanned consumables warehouses includes a warehouse management platform, which is connected to a pickup terminal and a supply terminal via communication.

[0012] The picking terminal generates a priority setting signal and sends it to the priority setting unit; the priority setting unit sets the priority; after the priority setting is completed, if the picking types are the same at the same time, the picking terminals are prioritized for picking; and the real-time allocation results are sent to the warehouse management platform.

[0013] The supplier generates a supply monitoring signal and sends it to the supply monitoring unit; the supply monitoring unit monitors the warehouse supply process; the monitoring unit classifies the picking type of the picking terminal based on the detection and sends it to the priority setting unit for priority readjustment;

[0014] The picking terminal generates a safety setting signal and sends it to the safety setting unit; the safety setting unit sets the safety of the picking process of the picking terminal; after the safety setting is completed, the supply terminal generates a consumable storage monitoring signal and sends it to the consumable storage monitoring unit; the consumable storage monitoring unit monitors the storage of consumables in the unmanned consumable warehouse.

[0015] Furthermore, the operation process of the priority setting unit is as follows:

[0016] Record the pickup terminals whose permissions are granted by the warehouse management system, where each pickup terminal specifically represents the person picking up the goods; extract data based on the pickup terminals to prioritize them;

[0017] Collect the pickup cycle of the pickup terminal and record the fluctuation trend of the pickup cycle within the currently set threshold time period, specifically the trend of shortening pickup cycle and the trend of increasing pickup cycle.

[0018] Within the corresponding trend period, the consumable utilization ratio of the pickup terminal is obtained. The consumable utilization ratio is calculated by collecting the sum of the expired and damaged quantities of the pickup terminal and the total usage of the pickup terminal.

[0019] Furthermore, when the demand for pickup type is consistent at the same pickup time in non-single pickup cycles, and the current inventory of consumables for the demand pickup type cannot meet the needs of all pickup terminals at the same time, priority is assigned.

[0020] If the current pickup cycle of the pickup terminal is trending downwards and the current cycle consumable utilization rate is not trending downwards, then the current pickup terminal will be marked as the lowest priority.

[0021] If the current pickup cycle of the pickup terminal is on an increasing trend, and the current cycle consumable utilization rate is on a decreasing trend, then the current pickup terminal will be marked as the highest priority; if neither of the above two situations applies, then the current pickup terminal will be marked as the medium priority.

[0022] Furthermore, the operation process of the supply monitoring unit is as follows:

[0023] Set a supply detection period and obtain the supply process of all picking terminals within the supply detection period. Record the supply type and the corresponding consumable storage time. Obtain the consumable storage time at each supply moment within the supply detection period and record the storage time of the remaining consumables in the current inventory of the same type. If the storage time of the remaining consumables exceeds the storage time of the supplied consumables, it is marked as inventory backlog consumables. When the inventory backlog consumables exceed the set consumable quantity threshold, the current supply process is marked as a backlog risk process; otherwise, it is marked as a normal outbound process.

[0024] Furthermore, when the risk of delays during the supply testing period reaches a set percentage threshold, the system enters the designated outbound phase. During this phase, the order of the pickup terminal's corresponding supply time and the order in which the corresponding consumables have been received are used as the matching criteria to match the pickup terminal with the consumables. A consumable number is set during pickup. If the set consumable number does not match the actual picked-up consumable number, the pickup process of the corresponding pickup terminal is marked as non-designated pickup; otherwise, it is marked as designated pickup.

[0025] Furthermore, the pickup type of each pickup terminal is recorded. The priority setting unit adjusts the priority of the pickup terminals set in the warehouse management platform according to the pickup type of the pickup terminal. When the pickup type of the pickup terminal is continuously non-standard pickup, or the cumulative frequency exceeds the set cumulative frequency threshold, the priority of the current pickup terminal is reduced, and when it is reduced to the lowest priority, the shortening span of the pickup cycle is restricted.

[0026] Furthermore, the operation process of the safety setting unit is as follows:

[0027] The unmanned consumables warehouse sets a replenishment cycle based on actual inventory and determines the replenishment period for placing consumables. If a pickup terminal issues a pickup request during the replenishment period, the current period is marked as a safe setting period. The location of the unmanned consumables warehouse replenishment equipment and the space occupied by the corresponding replenishment action of the replenishment equipment are obtained within the safe setting period. When the pickup request of the pickup terminal is always within the safe setting period, the corresponding pickup request time is marked as a safe setting time.

[0028] The location of the unmanned consumable warehouse replenishment equipment is planned based on the safe setting time. The required retrieval time of the retrieval terminal is set, and the predicted location trajectory and action trajectory of the replenishment equipment within the required retrieval time are obtained based on the required retrieval time and the operation progress of the replenishment equipment.

[0029] Furthermore, the set movement trajectory of the pickup terminal is determined and the set movement trajectory is screened. Based on the location of the replenishment equipment, the corresponding position of the set movement trajectory is extracted. Under the premise of ensuring the space occupied by the replenishment action corresponding to the action prediction trajectory, the reserved space of the position corresponding to the set movement trajectory is obtained. If the reserved space exceeds the set reserved space threshold, it indicates that the current position meets the requirements for being a set movement trajectory. Otherwise, it indicates that the current position does not meet the requirements for being a set movement trajectory.

[0030] If the location of the replenishment equipment in the current motion prediction trajectory meets the requirements, the current set motion trajectory will be retained; otherwise, it will be discarded. The set motion trajectory after screening is then available for the picking terminal to select.

[0031] Furthermore, the process of the consumables storage monitoring unit is as follows:

[0032] During the replenishment period, the outline of the box containing the consumables is scanned. The outline of the box is obtained based on the static state. The outline points are set according to the outer surface of the box and marked as the starting outline points. During the clamping process of the replenishment equipment, the pressure applied to the surface of the box containing the consumables is statistically analyzed.

[0033] Obtain the corresponding contour points of the box under the current applied pressure and mark them as moving state contour points. If the contour points do not match, mark the current moving state contour points as external abnormal trend contour points; otherwise, mark them as non-interference trend contour points. After replenishment, place the box containing the consumables in the designated position and perform contour recognition after placement. Compare the contour points in the placement state. If the contour point positions do not match, mark them as internal abnormal trend contour points; otherwise, mark them as non-abnormal trend contour points.

[0034] The positions of the external abnormal trend contour points and the starting contour points are compared to obtain the movement trajectory of the external abnormal trend contour points relative to the starting contour points, and this trajectory is set as the external abnormal trajectory. The positions of the internal abnormal trend contour points and the starting contour points are compared to obtain the movement trajectory of the internal abnormal trend contour points relative to the starting contour points, and this trajectory is set as the internal abnormal trajectory.

[0035] Furthermore, after the replenishment equipment finishes picking up the consumable box, if the abnormal trajectory of the external contour points on the surface of the consumable box does not stop being generated, it is marked as an external interference box; if the abnormal trajectory of the external contour points on the surface of the consumable box stops being generated, the currently placed consumable box is marked as an interference concealment box.

[0036] During the consumables box placement phase, if an inherent abnormal trajectory is generated at the surface contour points of the consumables box, it will be marked as an internally affected box; conversely, if no inherent abnormal trajectory is generated at the surface contour points of the consumables box, it will be marked as an internally stable box.

[0037] Compared with the prior art, the beneficial effects of the present invention are:

[0038] 1. By combining the fluctuating trend of the pickup cycle of pickup terminals with the consumable utilization ratio, a scientific classification of pickup priorities is achieved, avoiding the irrationality of prioritizing based solely on the urgency of demand. This ensures that when inventory is insufficient, consumables can be prioritized for pickup terminals with high utilization efficiency and urgent needs, thereby improving the utilization rate of consumable resources. Furthermore, the system can dynamically adjust priorities based on violation information from the supply monitoring unit, effectively constraining unauthorized pickup behavior, reducing non-standard pickups, and standardizing the pickup process. When multiple pickup terminals are at the same priority level, the consumable utilization ratio is used as a comparison standard, further optimizing priority decision-making at the same level, ensuring the rationality of resource allocation, and solving the problems of unscientific priority classification and insufficient violation constraints in the existing system.

[0039] 2. To address the safety hazards of picking up goods during replenishment periods, the system plans the movement trajectory of the picking terminal and filters it based on the predicted trajectory of the replenishment equipment's location and movement. This avoids path conflicts between the picking terminal and the replenishment equipment, ensuring the operational safety of the unmanned warehouse. By monitoring the actual picking trajectory of the picking terminal in real time, the system adjusts the status of the replenishment equipment promptly when the trajectory deviates, further reducing safety risks. It can also adjust the picking trajectory based on the abnormal box positions reported by the consumables storage monitoring unit, avoiding areas with potential safety hazards and improving the safety of the picking process. Simultaneously, it provides the picking terminal with selectable safe trajectories, balancing safety and picking efficiency, and solving the problems of insufficient coordination between replenishment and picking safety and untimely trajectory monitoring in existing systems.

[0040] 3. By monitoring the duration of consumables in the warehouse, the system accurately identifies consumables that are stuck in inventory. When the number of stuck consumables exceeds a threshold, the system promptly marks the process as a risk of stagnation, alerting warehouse management personnel to take action. This reduces the expiration and damage caused by long-term stagnation of consumables, lowers resource waste, and improves inventory turnover efficiency. After entering the designated outbound stage, the system accurately matches the picking terminal with the consumables, standardizing the outbound process and reducing non-designated picking. At the same time, the system records the picking type of the picking terminal and feeds it back to the priority setting unit, providing data support for priority adjustment. This forms a linkage mechanism of "supply monitoring - priority adjustment," solving the problems of untimely identification of inventory stagnation and inaccurate outbound matching in the existing system, and meeting the industry's needs for lean inventory management.

[0041] 4. By scanning and comparing the contours of consumable boxes, external anomalies (deformation during clamping) and internal anomalies (displacement and deformation after placement) can be identified in real time. Abnormal boxes can be marked in a timely manner to avoid damage to consumables caused by long-term storage of abnormal boxes. By assessing the risk of clamping actions, clamping pressure can be adjusted to reduce damage to the boxes during clamping and reduce consumable losses. Boxes with hidden interference are given priority for outbound processing, and packaging parameters are adjusted for boxes with internal influences, further optimizing consumable storage and outbound management and improving the safety and rationality of consumable storage. The box type is fed back to relevant units, providing data support for safety trajectory adjustment and inventory management, and solving the problems of insufficient monitoring of consumable storage and high loss rate in the existing system.

[0044] Figure 2 This is a flowchart of the priority setting unit in this invention. Detailed Implementation

[0045] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0047] Please see Figure 1 As shown, a warehouse management system for unmanned consumables warehouses includes a warehouse management platform, which is connected to a pickup terminal and a supply terminal via communication.

[0048] The pickup terminal communication connection has a priority setting unit and a security setting unit;

[0049] The supply-side communication connection includes a supply monitoring unit and a consumables storage monitoring unit;

[0050] Furthermore, the priority setting unit and the supply monitoring unit share data and cooperate interactively to set and monitor data;

[0051] Once the warehouse is established, the warehouse management platform establishes communication with all connected units and operates in coordination.

[0052] The warehouse management platform generates pickup monitoring signals and supply monitoring signals, and sends them to the pickup end and the supply end respectively.

[0053] Example 1

[0054] The picking end and the supply end work together, and at the same time, the corresponding priority setting unit and supply monitoring unit data are analyzed synchronously to complete warehouse management;

[0055] The pickup terminal generates a priority setting signal and sends it to the priority setting unit; the priority setting unit sets the priority; please refer to [link / reference]. Figure 2 As shown;

[0056] Record the pickup terminals whose permissions are granted by the warehouse management system, where the pickup terminal specifically refers to the person picking up the goods;

[0057] Data is extracted from the pickup terminal for priority allocation;

[0058] Collect the pickup cycle of the pickup terminal and record the fluctuation trend of the pickup cycle within the currently set threshold time period, specifically the trend of shortening pickup cycle and the trend of increasing pickup cycle.

[0059] Within the corresponding trend period, the consumable utilization ratio of the pickup terminal is obtained. The consumable utilization ratio is calculated by collecting the sum of the expired and damaged quantities of the pickup terminal and the total usage of the pickup terminal.

[0060] When the demand for pickup type is the same at the same pickup time in a non-single pickup cycle, and the current inventory of consumables for the demand pickup type cannot meet the needs of all pickup terminals at the same time, priority will be assigned.

[0061] If the current pickup cycle of the pickup terminal is trending downwards and the current cycle consumable utilization rate is not trending downwards, then the current pickup terminal will be marked as the lowest priority.

[0062] If the current pickup cycle of the pickup terminal is on an increasing trend, and the current cycle consumable utilization rate is on a decreasing trend, then the current pickup terminal will be marked as the highest priority.

[0063] If neither of the above two scenarios applies, for example, if the current pickup cycle of the pickup terminal is trending downwards, but the current cycle consumable utilization ratio is not trending downwards; if the current pickup cycle of the pickup terminal is trending upwards, but the current cycle consumable utilization ratio is not trending downwards; or if the current pickup cycle of the pickup terminal is neither trending upwards nor trending downwards, then the current pickup terminal will be marked as a mid-level priority terminal.

[0064] When multiple pickup terminals are at the same priority, the periodic consumables utilization ratio is used as the comparison standard data. The priority decision is made based on the comparison of the periodic consumables utilization ratio values, that is, the lower the periodic consumables utilization ratio, the higher the priority.

[0065] After priority settings are completed, when the pickup types are the same at the same time, the pickup terminals are prioritized for pickup; and the real-time prioritization results are sent to the warehouse management platform.

[0066] The supplier generates a supply monitoring signal and sends it to the supply monitoring unit.

[0067] After receiving the supply monitoring signal, the supply monitoring unit monitors the warehouse supply process.

[0068] Set a supply detection period and acquire the supply process of all picking terminals within the supply detection period. Record the supply type and the corresponding consumable storage time. Acquire the consumable storage time at each supply moment within the supply detection period and record the storage time of the remaining consumables in the current inventory of the same type. If the storage time of the remaining consumables exceeds the storage time of the supplied consumables, it is marked as inventory backlog consumables. When the inventory backlog consumables exceed the set consumable quantity threshold, the current supply process is marked as a backlog risk process; otherwise, it is marked as a normal outbound process.

[0069] When the risk of delays during the supply inspection period reaches a set percentage threshold, the system enters the designated outbound phase. During this phase, the order of the pickup terminals' corresponding supply times and the order in which the corresponding consumables have been received are used as the matching criteria to match the pickup terminals with the consumables. A consumable number is set during pickup. If the set consumable number does not match the actual picked consumable number, the pickup process of the corresponding pickup terminal is marked as non-designated pickup; otherwise, it is marked as designated pickup.

[0070] Record the pickup type of each pickup terminal and send it to the priority setting unit. After receiving it, the priority setting unit adjusts the priority of the pickup terminal set in the warehouse management platform according to the pickup type of the pickup terminal. When the pickup type of the pickup terminal is non-prescribed pickup continuously, or the cumulative frequency exceeds the set cumulative frequency threshold, the priority of the current pickup terminal is reduced, and when it is reduced to the lowest priority, the shortening span of the pickup cycle is restricted.

[0071] Example 2

[0072] In the previous embodiment, supply and pickup were managed. This embodiment, based on the previous embodiment, sets up security settings for pickup terminals and monitors the security of consumable storage.

[0073] The pickup terminal generates a security setting signal and sends it to the security setting unit;

[0074] After receiving the security setting signal, the security setting unit sets the security settings for the pickup process of the pickup terminal;

[0075] The unmanned consumables warehouse sets the replenishment cycle and determines the replenishment period based on the actual inventory. During the replenishment period, consumables are placed by robots and other intelligent devices. If a pickup terminal issues a pickup request during the replenishment period, the current period is marked as a safe set period.

[0076] Obtain the location of the unmanned consumables warehouse replenishment equipment and the space occupied by the corresponding replenishment action of the replenishment equipment within the safe set time period; when the pickup demand time of the pickup terminal is within the safe set time period, mark the corresponding pickup demand time as the safe set time.

[0077] The location of the unmanned consumable warehouse replenishment equipment is planned based on the safe setting time. The required retrieval time of the retrieval terminal is set, and the predicted location trajectory and action trajectory of the replenishment equipment within the required retrieval time are obtained based on the required retrieval time and the operation progress of the replenishment equipment.

[0078] Based on the real-time location and the predicted trajectory, as well as the location of the picking consumables, the set movement trajectory of the picking terminal is obtained. The set movement trajectory is then screened according to the predicted trajectory of the corresponding action of the replenishment equipment. The location of the replenishment equipment is used to extract the location corresponding to the set movement trajectory. While ensuring the space occupied by the replenishment action corresponding to the predicted action trajectory, the reserved space of the location corresponding to the set movement trajectory is obtained. If the reserved space exceeds the set reserved space threshold, it indicates that the current location meets the requirements for the set movement trajectory. Otherwise, it indicates that the current location does not meet the requirements for the set movement trajectory.

[0079] If the locations of replenishment equipment in the current predicted movement trajectory all meet the requirements, the current set movement trajectory is retained; otherwise, it is discarded. The set movement trajectories after screening are provided for the picking terminal to select. After the picking terminal selects the set movement trajectory, the picking trajectory of the picking terminal is monitored in real time. When the overlap between the actual picking trajectory and the set movement trajectory is lower than the set overlap threshold, the replenishment equipment around the actual picking trajectory is slowed down or stopped. Conversely, when the overlap between the actual picking trajectory and the set movement trajectory is not lower than the set overlap threshold, replenishment continues and the picking terminal's picking trajectory is continuously monitored. The overlap is represented by the number of movement points that are consistent when comparing trajectories.

[0080] After completing the security settings, the supplier generates a consumable storage monitoring signal and sends it to the consumable storage monitoring unit.

[0081] After receiving the consumable storage monitoring signal, the consumable storage monitoring unit monitors the consumable storage in the unmanned consumable warehouse.

[0082] During the replenishment period, the outline of the box containing the consumables is scanned. The outline of the box is obtained based on the static state. The outline points are set according to the outer surface of the box and marked as the starting outline points. During the clamping process of the replenishment equipment, the pressure applied to the surface of the box containing the consumables is statistically analyzed. Specifically, the pressure is obtained by setting a miniature pressure sensing unit (such as a piezoresistive thin film sensor) on the clamping surface.

[0083] Obtain the corresponding contour points of the box under the current pressure applied to the box surface and mark them as moving state contour points. Compare the moving state contour points with the starting contour points. If the contour points do not match, mark the current moving state contour points as external abnormal trend contour points; otherwise, mark them as non-interference trend contour points.

[0084] After replenishment is completed, the consumables are placed in the designated location in the box. After placement, contour recognition is performed. Contour points are compared while in place. If the contour points are not in the same position, they are marked as contour points with inherent abnormal trends; otherwise, they are marked as contour points without abnormal trends.

[0085] The positions of the external abnormal trend contour points and the starting contour points are compared to obtain the movement trajectory of the external abnormal trend contour points relative to the starting contour points, and this trajectory is set as the external abnormal trajectory. The positions of the internal abnormal trend contour points and the starting contour points are compared to obtain the movement trajectory of the internal abnormal trend contour points relative to the starting contour points, and this trajectory is set as the internal abnormal trajectory.

[0086] After the replenishment equipment finishes gripping, if the abnormal trajectory of the external contour points on the surface of the consumable box does not stop being generated, the current gripping action is set as a risk action and the gripping pressure of the current type of consumable box is reset. At the same time, the currently placed consumable box is marked as an external interference box. If the abnormal trajectory of the external contour points on the surface of the consumable box stops being generated, the currently placed consumable box is marked as a hidden interference box. The hidden interference box is monitored, and consumables in the hidden interference box are given priority for being removed from the warehouse during the picking stage of the picking terminal.

[0087] During the consumable box placement phase, if an inherent abnormal trajectory is generated at the surface contour points of the consumable box, the current type of consumable box will be marked as an inherently influencing box, and the box packaging parameters for the current type of consumable will be set, i.e., the box space will be changed or the packaging quantity will be reduced; conversely, if no inherent abnormal trajectory is generated at the surface contour points of the consumable box, the current type of consumable box will be marked as an inherently stable box.

[0088] Send the consumable container type to the supplier and forward it to the warehouse management platform;

[0089] After the supplier receives the goods, the safety setting unit will screen the set movement trajectory of the picking terminal based on the location of the external interference box and the internal influence box. If the cleaning has not been completed and the box is within the set movement trajectory determined by the picking terminal, the selection priority will be reduced and the non-current set movement trajectory will be selected first.

[0090] After setting the movement trajectory, the actual pickup trajectory of the pickup terminal is uploaded to the warehouse management platform and stored as a management log.

[0091] The acquisition method is disclosed based on the thresholds used in the processing of each of the above units:

[0092] Cumulative frequency threshold: Used to determine whether the priority of the pickup terminal needs to be reduced. It is derived from combining the warehouse management regulations and the pickup terminal's historical violations to balance the strictness of management with the flexibility of pickup, and to avoid excessive penalties for a single violation or a small number of violations.

[0093] Acquisition method: Based on warehouse management requirements and combined with the violation records of pickup terminals in the past 6 months, the average violation frequency is calculated, and 1.5 times the average violation frequency is used as the cumulative frequency threshold. If the cumulative violation frequency of a pickup terminal exceeds this threshold, or if there are 3 consecutive non-standard pickups, the priority will be reduced. At the same time, the threshold can be appropriately lowered for newly registered pickup terminals, and the threshold can be appropriately increased for pickup terminals with no historical violation records.

[0094] Reserved space threshold: Used to determine whether the corresponding position of the set movement trajectory of the picking terminal meets the safety requirements. It is derived from combining the space occupied by the replenishment equipment and the movement space requirements of the picking terminal to avoid collisions between the picking terminal and the replenishment equipment and ensure operational safety.

[0095] Acquisition method: Measure the maximum space occupied by the replenishment equipment during different actions (clamping, placing), and add the safe movement distance of the picking terminal (usually 0.3-0.5 meters) as the reserved space threshold; at the same time, dynamically adjust the threshold according to the model of the replenishment equipment and the size of the picking terminal. The threshold for large replenishment equipment or picking terminals can be appropriately increased.

[0096] Pickup trajectory overlap threshold: Used to determine whether the actual pickup trajectory of the pickup terminal is compliant. It is derived from combining the planning accuracy of the pickup trajectory and the operation error of the pickup terminal to balance safety and efficiency and avoid unnecessary equipment slowdown or stoppage due to slight deviation.

[0097] Acquisition method: By simulating the normal and abnormal pickup trajectories of the pickup terminal multiple times, the reasonable range of trajectory overlap is statistically analyzed, and 80% is used as the overlap threshold. If the overlap between the actual pickup trajectory and the set movement trajectory is less than 80%, it is judged as trajectory deviation, triggering the replenishment equipment to slow down or stop. At the same time, according to the operator proficiency of the pickup terminal, the threshold can be appropriately lowered for novice pickup terminals (e.g., 75%), and appropriately increased for experienced pickup terminals (e.g., 85%).

[0098] Inventory backlog threshold: Used to determine whether the current supply process is a risky process of backlog. It is derived from combining the warehouse storage capacity, the shelf life of the consumables, and the historical cost of handling backlog consumables, in order to avoid excessive backlog consumables occupying warehouse space and causing consumables to be damaged.

[0099] Acquisition method: Based on the actual storage capacity of the warehouse and the shelf life of various consumables, calculate the maximum allowable amount of consumables to be retained for each type (usually 10%-15% of the total inventory of such consumables) as the threshold for the amount of consumables to be retained in inventory; at the same time, referring to the standards of the industry's inventory early warning mechanism, the threshold for easily expired and easily damaged consumables can be appropriately reduced (e.g., 5%-10%), and the threshold for durable consumables can be appropriately increased (e.g., 15%-20%), and dynamically adjusted according to historical retention data.

[0100] Threshold for the proportion of delay risk processes: This is used to determine whether to enter the designated outbound stage. It is designed to combine the warehouse's supply efficiency goals with the impact of delay risks to avoid excessive triggering of outbound designation due to a small number of delay risk processes, which would affect the normal supply process.

[0101] Acquisition method: Count the number of processes with lingering risks during the supply monitoring period in the past 3 months, calculate the average percentage, and use 20% as the percentage threshold. If the percentage of processes with lingering risks during the supply monitoring period exceeds 20%, the process will enter the designated outbound stage. At the same time, the threshold can be adjusted according to the warehouse's operational goals. If the focus is on optimizing inventory turnover in the near future, the threshold can be lowered to 15%. If the supply pressure is high, the threshold can be increased to 25%.

A warehouse management system for unmanned consumables warehouses according to claim 2, characterized in that, When the demand for pickup type is the same at the same pickup time in a non-single pickup cycle, and the current inventory of consumables for the demand pickup type cannot meet the needs of all pickup terminals at the same time, priority will be assigned. If the current pickup cycle of the pickup terminal is trending downwards and the current cycle consumable utilization rate is not trending downwards, then the current pickup terminal will be marked as the lowest priority. If the current pickup cycle of the pickup terminal is on an increasing trend, and the current cycle consumable utilization rate is on a decreasing trend, then the current pickup terminal will be marked as the highest priority. If neither of the above two scenarios applies, the current pickup terminal will be marked as a mid-level priority terminal.

4. A warehouse management system for unmanned consumables warehouses according to claim 1, characterized in that, The operation process of the supply monitoring unit is as follows: Set a supply detection period and obtain the supply process of all picking terminals during the supply detection period. Record the supply type and the corresponding consumable storage time. Obtain the consumable storage time at each supply moment during the supply detection period. Record the storage time of the remaining consumables in the current inventory of the same type. If the storage time of the remaining consumables exceeds the storage time of the supplied consumables, they are marked as inventory stagnant consumables. When the inventory of consumables exceeds the set consumable quantity threshold, the current supply process is marked as a process with a risk of inventory buildup. Conversely, it is marked as a normal outbound process.

5. A warehouse management system for unmanned consumables warehouses according to claim 4, characterized in that, When the risk of delays during the supply inspection period reaches a set percentage threshold, the system enters the designated outbound phase. During this phase, the order of the pickup terminal's corresponding supply time and the order in which the corresponding consumables have been received are used as the matching criteria to match the pickup terminal with the consumables. A consumable number is set during pickup. If the set consumable number does not match the actual picked-up consumable number, the pickup process of the corresponding pickup terminal is marked as non-designated pickup; otherwise, it is marked as designated pickup.

6. A warehouse management system for unmanned consumables warehouses according to claim 1, characterized in that, The pickup type of each pickup terminal is recorded. The priority setting unit adjusts the priority of the pickup terminals set in the warehouse management platform according to the pickup type. When the pickup type of the pickup terminal is non-standard pickup for a continuous period of time, or the cumulative frequency exceeds the set cumulative frequency threshold, the priority of the current pickup terminal is reduced. When the priority is reduced to the lowest level, the shortening span of the pickup cycle is restricted.

7. A warehouse management system for unmanned consumables warehouses according to claim 1, characterized in that, The operation process of the safety setting unit is as follows: The unmanned consumables warehouse sets the replenishment cycle based on the actual inventory and determines the replenishment period for placing consumables. If a pickup terminal issues a pickup request during the replenishment period, the current period is marked as a safe period. Obtain the location of the unmanned consumables warehouse replenishment equipment and the space occupied by the corresponding replenishment action of the replenishment equipment within the safe set time period; when the pickup demand of the pickup terminal is always within the safe set time period, mark the corresponding pickup demand time as the safe set time; The location of the unmanned consumable warehouse replenishment equipment is planned based on the safe setting time. The required retrieval time of the retrieval terminal is set, and the predicted location trajectory and action trajectory of the replenishment equipment within the required retrieval time are obtained based on the required retrieval time and the operation progress of the replenishment equipment.

8. A warehouse management system for unmanned consumables warehouses according to claim 7, characterized in that, Determine the set movement trajectory of the picking terminal and perform set movement trajectory screening. Based on the location of the replenishment equipment, extract the corresponding position of the set movement trajectory. Under the premise of ensuring the space occupied by the replenishment action corresponding to the action prediction trajectory, obtain the reserved space of the position corresponding to the set movement trajectory. If the reserved space exceeds the set reserved space threshold, it indicates that the current position meets the requirements for being a set movement trajectory. Otherwise, it indicates that the current position does not meet the requirements for being a set movement trajectory. If the location of the replenishment equipment in the current motion prediction trajectory meets the requirements, the current set motion trajectory will be retained; otherwise, it will be discarded. The set motion trajectory after screening is then available for the picking terminal to select.

9. A warehouse management system for unmanned consumables warehouses according to claim 1, characterized in that, The process of the consumables storage monitoring unit is as follows: During the replenishment period, the outline of the box containing the consumables is scanned. The outline of the box is obtained based on the static state. The outline points are set according to the outer surface of the box and marked as the starting outline points. During the clamping process of the replenishment equipment, the pressure applied to the surface of the box containing the consumables is statistically analyzed. Obtain the corresponding contour points of the box under the current applied pressure and mark them as moving state contour points. If the contour points do not match, mark the current moving state contour points as external abnormal trend contour points; otherwise, mark them as non-interference trend contour points. After replenishment, place the box containing the consumables in the designated position and perform contour recognition after placement. Compare the contour points in the placement state. If the contour point positions do not match, mark them as internal abnormal trend contour points; otherwise, mark them as non-abnormal trend contour points. The positions of the external abnormal trend contour points and the starting contour points are compared to obtain the movement trajectory of the external abnormal trend contour points relative to the starting contour points, and this trajectory is set as the external abnormal trajectory. The positions of the internal abnormal trend contour points and the starting contour points are compared to obtain the movement trajectory of the internal abnormal trend contour points relative to the starting contour points, and this trajectory is set as the internal abnormal trajectory.

10. A warehouse management system for unmanned consumables warehouses according to claim 9, characterized in that, After the replenishment equipment finishes picking up the consumable box, if the abnormal trajectory of the external contour points on the surface of the consumable box does not stop being generated, it is marked as an external interference box; if the abnormal trajectory of the external contour points on the surface of the consumable box stops being generated, the currently placed consumable box is marked as an interference concealment box. During the consumables box placement phase, if an inherent abnormal trajectory is generated at the surface contour points of the consumables box, it will be marked as an internally affected box; conversely, if no inherent abnormal trajectory is generated at the surface contour points of the consumables box, it will be marked as an internally stable box.
