Description

TECHNICAL FIELD

[0001] The present application relates to the field of industrial automation control, in particular to a partition control method and device for warehouse hanger inbound and outbound. BACKGROUND

[0002] In modern clothing warehouse logistics, hangers are the core carriers for carrying finished clothing products. The rapid and accurate inbound and outbound of hangers in high-density storage areas is the key to improving warehouse throughput and operational efficiency. Efficient scheduling and control of hanger flow paths directly determine the operation continuity and order response capability of the entire warehouse system.

[0003] The existing control technology for warehouse hanger inbound and outbound is usually based on a global unified scheduling logic. After assigning a target bin to each hanger, the system controls the push rod to transport the hanger to the specified location. The disadvantage of this scheme is that the system regards all bins as homogeneous resources and uses a fixed strategy of first-in-first-out or random allocation for scheduling, resulting in a significant reduction in operation efficiency in large-scale warehouse scenarios.

For example, the terminal may also include components that are larger than... Figure 1 The more or fewer components shown, or having the same Figure 1The different configurations shown are illustrated.

[0052] This embodiment provides a zoned control method for the entry and exit of warehouse clothes racks. Figure 2 This is a flowchart of the zoning control method for the entry and exit of warehouse hangers in this embodiment, as shown below. Figure 2 As shown, the process includes the following steps:

[0053] Step S210: Obtain the hanger entry information of the recognition module in real time.

[0054] Specifically, the information on the arrival of the clothes hangers is collected through radio frequency identification (RFID) readers deployed at key nodes of the suspended track; it can also be acquired through photoelectric sensors deployed at key nodes of the suspended track; or it can be acquired through a machine vision module. There are no restrictions on the method used to acquire the information on the arrival of the clothes hangers.

[0055] Step S220: Determine the target storage location corresponding to the hanger based on the hanger entry information and the pre-built entry and exit partitions.

[0056] Specifically, target storage locations can be determined through matching based on preset rules; allocation can also be based on predictive analysis of inbound information and partition status using machine learning models; or optimal selection can be achieved by real-time querying and calculation of the load and distance costs of storage locations within each partition. No restrictions are placed on the specific decision-making method for matching target storage locations.

[0057] Step S230: Generate scheduling instructions based on the inbound / outbound partitions and the target storage location.

[0058] Specifically, scheduling instructions can be sent directly after generation; alternatively, a real-time priority evaluation mechanism can be introduced to dynamically attach execution priority tags to instructions based on the current system load; and instruction sequence optimization algorithms can be used to sort and merge multiple scheduling instructions to be executed, thereby improving overall execution efficiency. No restrictions are placed on the strategy for issuing scheduling instructions.

[0059] Step S240: According to the scheduling instruction, control the push rod assembly to transport the clothes hanger to the target storage location.

[0060] Specifically, upon receiving a scheduling command, the corresponding push rod assembly is driven to move towards the target storage location. After the hanger arrives at the target storage location, it sends hanger arrival information to the control module. The control module receives the location information and records it in the scheduling log. The operation control process can employ different control methods such as continuous control, segmented positioning, or adaptive speed regulation; no restrictions are placed on the control method here.

[0061] Through the above steps, an inbound and outbound partitioning system was constructed that effectively improves work efficiency, enabling the warehouse layout to adapt to business fluctuations, thereby preventing congestion and optimizing resource allocation. This solves the problem of significantly reduced operational efficiency in large-scale warehousing scenarios found in related technologies, and achieves improved operational efficiency in such scenarios.

[0062] The above steps are explained in detail below:

[0063] In some embodiments, step S220 determines the target storage location corresponding to the hanger based on the hanger's entry information and the pre-built entry / exit partitions, such as... Figure 3 As shown, it includes the following steps:

[0064] Step S221: Determine the target partition corresponding to the hanger based on the clothing attribute information in the hanger entry information and the pre-built entry and exit partitions;

[0065] Step S222: Determine the target storage location of the hanger in the target partition based on the target storage location type in the hanger entry information.

[0066] Specifically, firstly, based on the clothing attribute information and the pre-built inbound / outbound partitions, the hangers are matched to the preset partitions. The clothing attribute information includes, but is not limited to, clothing category, best-selling level, and material type; there are no restrictions on the attribute categories included in the clothing attribute information.

[0067] After selecting a partition, select a suitable available storage location within the target partition based on the target storage location type. The target storage location type includes, but is not limited to, cut pieces, semi-finished products, and final inspection. There are no restrictions on the data types included in the target storage location type.

[0068] This embodiment employs a hierarchical decision-making mechanism of first partitioning and then selecting locations, ensuring the applicability of specific storage locations in terms of physical specifications and real-time status. This improves the utilization rate of warehouse space and the overall smoothness of inbound and outbound operations.

[0069] In some embodiments, the method for zoned control of warehouse hanger entry and exit is as follows: Figure 4 As shown, it also includes the following steps:

[0070] Step S310: When constructing the inbound / outbound partition, obtain multi-dimensional input parameters; the input parameters include the order creation parameters issued by the communication module, the running status parameters fed back by the push rod component, and the stored historical running data;

[0071] Step S320: Based on the preset parameter weight values, the order processing parameters, running status parameters and historical running data in the input parameters are weighted and summed to obtain the partition matching score;

[0072] Step S330: Determine the inbound / outbound partitions based on the partition matching score and the preset partition threshold.

[0073] Specifically, after receiving the entry information, the system combines the overall storage location status stored in the control module with the data to divide the area into different zones using a dynamic partitioning algorithm. The algorithm's input parameters include storage area operation status parameters (such as the number of available storage locations in each zone, real-time push lever load rate, task queue length, and storage area congestion index), order processing parameters (such as clothing best-selling level, order priority, storage timeliness requirements, and load weight), and historical operation data (such as the frequency of entry and exit from each zone in the past 72 hours, misplacement rate, and task response time). The algorithm assigns initial weights to the parameters; for example, order priority has a weight of 0.3, storage area congestion index has a weight of 0.25, best-selling level has a weight of 0.2, available storage location percentage has a weight of 0.15, and historical operation data has a weight of 0.1.

[0074] Next, the parameters are weighted and summed according to preset parameter weight values ​​to obtain the partition matching score. The formula for calculating the partition matching score is:

[0075] ;

[0076] in, For partition matching score, These are the parameter weight values. For parameter values.

[0077] After obtaining the partition matching score, the partition matching score is compared with the preset partition threshold. Based on the comparison result, the corresponding inbound / outbound partition is determined. The inbound / outbound partitioning method can also be based on machine learning classification models or multi-objective optimization algorithms; there are no restrictions on the method of inbound / outbound partitioning here.

[0078] This embodiment enables dynamic partitioning of inbound and outbound zones based on real-time warehouse operation status, order characteristics, and historical data. Through quantitative evaluation and dynamic threshold determination, precise matching of warehouse space resources with task requirements is achieved.

[0079] In some embodiments, step S330 determines the inbound / outbound partitions based on the partition matching score and a preset partition threshold, such as... Figure 5 As shown, it includes the following steps:

[0080] Step S331: If the partition matching score is greater than or equal to the partition threshold, then the partition corresponding to the partition matching score is determined as the first partition.

[0081] Step S332: If the partition matching score is less than the partition threshold, then the partition corresponding to the partition matching score is determined as the second partition.

[0082] Specifically, when the partition matching score is greater than or equal to the partition threshold (e.g., 80 points), this partition is identified as the first partition, which is a high-frequency, fast-flow area with frequent inbound and outbound traffic. When the matching score is less than the partition threshold, this partition is identified as the second partition, which is a low-frequency, slow-flow area with inbound and outbound traffic. The partition threshold serves as the criterion for distinguishing between the first and second partitions and is set according to the load conditions; therefore, the value of the partition threshold is not limited here.

[0083] This embodiment introduces a threshold-based partitioning mechanism, which significantly improves resource utilization efficiency. Furthermore, the dynamically adjustable threshold parameters enable the system to flexibly adapt to different production modes and real-time load changes. This ensures the rationality of partitioning selection and resource utilization while guaranteeing the overall scheduling performance and operational stability of the warehousing system in high-concurrency, multi-tasking scenarios.

[0084] In some embodiments, the zoning control method for the entry and exit of warehouse hangers further includes the following steps:

[0085] After the inbound / outbound partition reaches the preset cycle, update the partition range of the inbound / outbound partition.

[0086] Specifically, after a preset time period (e.g., 10 minutes), a more efficient partition layout scheme is recalculated and generated based on a dynamic partitioning algorithm, with the number of partitions adjusted at one time not exceeding 20% ​​of the total number of partitions. Afterwards, the new partition range configuration parameters are synchronized to the control module, completing the dynamic adjustment and switching of the partition logical range. Partition updates can also be triggered by reaching a preset task processing batch or a preset system maintenance window. No restrictions are placed on the triggering method for partition updates.

[0087] This embodiment upgrades warehouse zoning control from static configuration to dynamic optimization and adaptive capabilities. It enables periodic re-optimization of the zoning layout, thereby continuously improving warehouse space utilization and balancing the workload of each zoning area.

[0088] In some embodiments, the method for zoned control of warehouse hanger entry and exit is as follows: Figure 6 As shown, it also includes the following steps:

[0089] Step S241: During the process of controlling the push rod assembly to transport the clothes hanger to the target storage location, compensation parameters are collected synchronously; and the compensation amount is determined based on the compensation parameters.

[0090] Step S242: Based on the compensation amount, the lever value of the push rod assembly is corrected.

[0091] Specifically, the baseline values ​​for each position of the push rod are first calibrated and cached under standard environmental conditions (temperature 25℃, friction coefficient 0.2, no load). Compensation parameters are collected synchronously during push rod operation, and the compensation amount is calculated using an error compensation matrix after comparison with the baseline values. For example, when the temperature rises to 50℃ and the friction coefficient decreases by 0.08, the number of motor rotations increases by an additional 2%; when the motor current rises to 2.5A, the pulse width modulation (PWM) duty cycle is reduced by 5%, and the deceleration distance is extended.

[0092] Afterwards, the compensation amount is input into the PID controller to adjust the motor drive signal. When the PWM drive unit controls the push rod to run, it collects the motor current (normal range: 0.5-2A) and track temperature (normal range: -10℃-60℃) in real time. If an abnormal current (≥3A) or temperature exceeds the limit, the machine immediately stops and feedback is sent to the main controller. After the push rod reaches its position, the position sensor is triggered and an execution completion signal is uploaded to the control module, which updates the storage position status to occupied. Simultaneously, the position is verified using a laser displacement sensor; if the error is greater than 0.5cm, secondary compensation is triggered and the reference rod value cache is updated. Furthermore, the algorithm can adapt to abnormal operating conditions: when the track vibration amplitude is greater than 0.1mm, the parameter acquisition frequency is increased to 2ms / time and the differential adjustment weight is increased; when the push rod has been used for more than 5000 hours, the motor current compensation weight is increased to offset mechanical wear.

[0093] It is understood that the specific values ​​and ranges mentioned above can be configured and adjusted according to the actual working environment, equipment characteristics, etc., and are not limited to the fixed values ​​listed.

[0094] This embodiment introduces a complete closed-loop control system with environmental adaptation and dynamic compensation, replacing the traditional rigid actuator drive that relies on fixed parameters with dynamic control that can sense operating conditions in real time and automatically correct deviations. This effectively overcomes execution errors caused by temperature changes, friction fluctuations, mechanical wear, and load differences, ensuring high-precision positioning of the actuator under various complex and non-standard operating conditions.

[0095] This embodiment also provides a zone control device for the entry and exit of warehouse clothes racks, including a control module and an identification module, a communication module and at least one push rod assembly respectively connected to the control module;

[0096] The control module is used to execute any of the zoning control methods for the entry and exit of warehouse hangers in the above embodiments;

[0097] The identification module is used to collect information about the clothes hangers entering the station;

[0098] The communication module is used to enable data interaction between the control module and the upper-level management system.

[0099] Push rod assembly used to transport clothes hangers to the target storage location.

[0100] Specifically, the control module is responsible for overall scheduling and communication, as well as precise control of the push rods in each area. The identification module adopts a multi-channel card reader architecture to collect information on incoming hangers. The communication module supports a dual-link redundancy design. The main link uses industrial Ethernet (TCP / IP protocol) to achieve data interaction with the upper-level management system, and the backup link uses a 4G / 5G module, automatically switching when the main link is interrupted (switching time ≤ 1s). Data transmission uses the Advanced Encryption Standard (AES) algorithm to ensure the security of hanger information transmission and prevent information leakage or tampering. The push rod assembly is used to respond to scheduling instructions and transport the hangers to the designated storage location. The encryption algorithm can also be an asymmetric encryption algorithm or a national cryptographic algorithm; there is no restriction on the type of encryption algorithm used.

[0101] This embodiment utilizes modular and distributed design to achieve centralized identification, zoned control, and collaborative scheduling of the entire process of clothes hangers entering and leaving the station. While ensuring high accuracy and high reliability, it reduces hardware costs and maintenance complexity, making it suitable for large-scale warehouse automation scenarios.

[0102] In some embodiments, the identification module includes a master card reader and at least one slave card reader connected to the master card reader;

[0103] From the card reader, used to read the hanger label information;

[0104] The main card reader, connected to the control module, is used to summarize and process hanger label information and generate hanger entry information.

[0105] Specifically, the identification module adopts a multi-channel reader architecture with one master reader and N slave readers. The master reader integrates a signal enhancement unit and an anti-interference filtering circuit, and connects to N slave readers (N≤16) via a CAN bus protocol to cover all entrances. The bus protocol can also be RS232 or RS485; the type of bus protocol is not limited here. The reader is equipped with an ultra-low frequency RFID read / write chip, with a read / write distance of 0.5cm-11cm and an identification speed ≤50ms / time. Simultaneously, a signal strength detection unit is added, which automatically activates gain adjustment when the signal strength is below -60dBm to ensure an identification accuracy of ≥99.9% in complex warehouse environments.

[0106] For example, when a hanger enters the entrance, the corresponding RFID tag information is collected by the slave reader and transmitted to the master reader. The master reader optimizes the signal quality through a signal enhancement unit, filters out industrial electromagnetic interference (such as noise generated by motor start-up and shutdown), and extracts the hanger's entry information from the tag. The master reader synchronizes the hanger's entry information to the control module and simultaneously sends a "successful identification" signal to the slave reader. If identification fails (e.g., signal interruption), a re-identification is triggered, with a maximum of 3 retries. If it still fails, it is reported through the communication module and marked as an abnormal hanger.

[0107] It is understood that the specific values ​​and ranges mentioned above can be configured and adjusted according to the actual working environment, equipment characteristics, etc., and are not limited to the fixed values ​​listed.

[0108] This embodiment employs a master-slave distributed card reader architecture, achieving efficient, reliable, and large-scale collection of hanger entry information. Compared to the existing one-reader-per-entry solution, hardware procurement costs are reduced by over 30%, cabling length is reduced by 60%, and a single reader failure only affects the corresponding slave channel, allowing the master channel to temporarily take over. The average fault resolution time is shortened to less than 0.5 hours. This significantly improves the real-time performance and accuracy of hanger identification, enhancing the adaptability and maintainability of the entire hanging system in complex, large-scale production lines.

[0109] In some embodiments, the control module includes a main controller and at least one partition controller connected to the main controller;

[0110] The main controller, connected to the main card reader, is used to receive and process hanger entry information and generate scheduling instructions;

[0111] The zone controller, connected to the push rod assembly, is used to control the push rod assembly to perform the hanger delivery operation according to the scheduling instructions.

[0112] Specifically, the control module adopts a distributed controller architecture, with one main controller and M partition controllers (M is configured according to the size of the storage area, with a maximum support of 64). The main controller and partition controllers have identical hardware, both using ARM Cortex-M4 processors (200MHz). The controllers can also use ARM Cortex-M0 / M3 / M7 series, RISC-V architecture processors, or digital signal processors; there is no restriction on the type of main controller.

[0113] The main controller stores global storage location information, receives and processes hanger arrival information, generates scheduling instructions containing partition numbers, storage location coordinates, and push rod numbers, and then distributes these instructions to the relevant partition controllers. Each partition controller is responsible for the precise control of the push rods within its jurisdiction, driving the push rod assemblies to complete a series of operations including hanger grabbing, transporting, and releasing. The partition controller integrates an encoder interface (supporting incremental encoder signal acquisition) and a PWM drive unit, achieving a control accuracy of 0.1mm.

[0114] The main controller and the zone controllers employ a three-stage communication mechanism of "command issuance - status feedback - confirmation response," building a bidirectional communication link based on the CANopen industrial bus protocol, ensuring a communication latency of ≤10ms. Simultaneously, an integrated task priority scheduling unit categorizes hanger entry and exit tasks into three levels: urgent (e.g., expedited orders), routine, and low priority (e.g., restocking). Emergency task response time is ≤50ms, and routine task response time is ≤100ms. A congestion prediction unit is added; by analyzing the operating status of each zone's push levers and the task queue length, it automatically triggers task diversion when the congestion index of a certain area exceeds a threshold (80%).

[0115] It is understood that the specific values ​​and ranges mentioned above can be configured and adjusted according to the actual working environment, equipment characteristics, etc., and are not limited to the fixed values ​​listed.

[0116] This embodiment employs a master-slave, distributed control architecture, achieving decoupling and coordination between scheduling logic and execution control. The master controller focuses on global optimization and decision-making, ensuring the overall efficiency and orderliness of the system's operation; while the partition controllers are responsible for rapid and accurate responses in their local areas, reducing the reliance on the real-time performance of the central processing unit and the communication load.

[0117] In some embodiments, the zoning control device for the entry and exit of warehouse hangers also includes a status detection module;

[0118] The status detection module, connected to the control module, is used to perform multi-dimensional status detection and verification of the exit clothes rack.

[0119] Specifically, at the exit end, photoelectric sensors (to detect the presence of hangers), laser displacement sensors (to detect hanger positions), and miniature weight sensors (to detect the load status) are installed. Data from these three dimensions is fused using a Kalman filter algorithm. This constructs a five-dimensional verification model integrating card number, RFID information, location coordinates, time stamp, and weight data, replacing the original single photoelectric detection and reducing the false match rate to below 0.1%. The push lever status recognition uses a combined signal and parameter judgment. By combining the card reading signal, operating speed (≥0.2m / s for effective operation), and weight data, a linked judgment is achieved, resulting in an empty / present lever recognition accuracy of ≥99.9%.

[0120] For example, when the push rod moves the hanger to the exit end, the status detection module simultaneously collects photoelectric signals (whether the hanger is present), laser position data (deviation ≤ 0.5cm), and weight data. After the multi-dimensional data is fused by Kalman filtering, it is compared with the hanger information stored in the main controller for five-dimensional verification. If the verification passes, the hanger is allowed to pass and the storage location status is updated to "idle". If the verification fails, an alarm is triggered and the hanger is locked to prevent misclassification.

[0121] This embodiment adds an independent, multi-dimensional automated detection and verification node to the hanger outgoing process, achieving closed-loop verification of hanger load integrity, location compliance, and task consistency. It effectively intercepts erroneous outgoing behaviors caused by mechanical malfunctions, human error, or system synchronization problems, fundamentally avoiding the risk of material flow errors and subsequent production interruptions.
