Description

Technical Field

[0001] This invention relates to the field of spacer bar receiving and dispatching technology, and more specifically, to a control method and system for automatic receiving and dispatching of spacers bar. Background Technology

[0002] In the aluminum profile production process, spacers are crucial auxiliary tools used to maintain spacing and prevent surface damage during stacking, handling, and storage. They are widely used in processes such as frame removal and assembly. In existing production methods, the collection and distribution of spacers largely rely on manual operation. Workers must collect the scattered spacers one by one during frame removal and then manually place them according to process requirements during assembly. This method is not only labor-intensive but also limited by the speed and accuracy of manual operation, often leading to confusion, loss, or misalignment of spacers during transmission, thus affecting the overall logistics efficiency and stacking quality of the aluminum profiles.

[0003] As aluminum profile manufacturers expand their production scale and increase automation, the shortcomings of manual methods have become increasingly apparent. Low efficiency in spacer bar receiving and dispatching has become a bottleneck in production cycle time, limiting the coordinated operation of upstream and downstream equipment. Manual operation is unstable, easily leading to uneven distribution or incorrect stacking of spacers, causing misalignment of profiles during framing and increasing the probability of rework. Although some production lines have attempted to improve the receiving and dispatching process by setting up manual auxiliary trolleys and temporary storage racks, it is still impossible to achieve fully automated and orderly management of the entire process of spacer bar collection, storage, and distribution. Summary of the Invention

[0004] In view of this, the present invention proposes a control method and system for automatic collection and distribution of spacers, which aims to address the problems of low efficiency, high labor intensity, transmission confusion and misalignment caused by manual operation in the collection and distribution of spacers in the prior art, thereby restricting the level of automation and overall logistics efficiency of aluminum profile production.

[0005] In one aspect, the present invention proposes a control method and system for automatic sending and receiving of spacers, comprising:

[0006] Acquire location information, direction of movement information, timestamp information, usage frequency information, and anomaly marker information during the transmission and reception process of the interleaved strip;

[0007] The process of sending and receiving strips is divided into the receiving stage, the temporary storage stage, and the sending stage.

[0008] During the receipt stage, the entry path of the strip is sequentially compared based on the location information and the direction of movement information. When the location information is continuously missing or the direction of movement is reversed, the path abnormality mark information is obtained. The timestamp information is used to determine whether there is a continuous arrival interval abnormality. When there is a continuous arrival interval abnormality, the delay abnormality mark information is obtained.

[0009] During the temporary storage phase, management areas are divided based on the location information when the spacer arrives, and each management area is defined as a storage unit. Balance is determined based on usage frequency information and historical records to obtain the balance determination result. When it is determined that the number of consecutive receptions in a certain storage unit exceeds the normal distribution range, a reception limit instruction is output and the newly arrived spacer is assigned to a nearby storage unit. When a spacer in a storage unit is marked by path anomaly marker information or delay anomaly marker information, the storage unit is determined to be an abnormal storage unit, and the reception of spacers in that storage unit is suspended. If no path anomaly marker information or delay anomaly marker information associated with that storage unit is generated in subsequent transmission and reception cycles, the suspension is lifted and the reception function of that storage unit is restored.

[0010] During the winding phase, priority determination rules are established for several concurrent objects to be wound based on path anomaly marker information, delay anomaly marker information, and balance determination results.

[0011] When several pending message objects are determined to be in the same priority category, they are judged sequentially according to the timestamp information. If several pending message objects have the same sequential judgment result, the pending message objects are postponed to the next send / receive cycle and re-enter the priority judgment in the subsequent send / receive cycle.

[0012] Furthermore, when performing a sequential comparison of the entry path of the spacer based on the location information and the direction of movement information, it includes:

[0013] Preset path and preset direction information are obtained based on historical operation records;

[0014] The position information of the spacer during the sending and receiving process is matched with the preset path information segment by segment, and the movement direction information of the spacer is compared with the preset direction information one by one.

[0015] When location information is missing from the preset path information, record the missing segment;

[0016] When the direction of motion information is opposite to the preset direction information, record the reversed segment;

[0017] When the number of consecutive occurrences of missing segments exceeds a preset judgment threshold, or when the movement direction information is detected to be opposite to the preset direction information at adjacent collection points, it is determined that there is an anomaly in the entry path of the partition, path anomaly marker information is obtained, and the path anomaly marker information and the corresponding partition are recorded. The preset judgment threshold is obtained based on the statistical results of historical operation records.

[0018] Furthermore, when determining whether there are abnormal consecutive arrival intervals based on timestamp information, this includes:

[0019] Based on the distribution of arrival timestamps of the intervals under normal operating conditions in the historical operation records, the reference range for consecutive arrival intervals is determined;

[0020] The actual arrival timestamp of each interval is calculated by comparing it with the actual arrival timestamp of the previous interval to obtain the time interval between the arrival of the two intervals, and the time interval is compared with the reference range obtained from historical operation records.

[0021] When a single time interval exceeds the reference range, an abnormal interval is recorded.

[0022] When an abnormal interval appears in two or more consecutive comparison results, it is determined to be a continuous arrival interval anomaly, and the delay anomaly marker information is obtained.

[0023] Furthermore, when determining the balance based on usage frequency information and historical records, the following are included:

[0024] During the temporary storage phase, usage frequency information for each storage unit is collected, and usage frequency distribution files for each storage unit are constructed based on historical operation records.

[0025] The number of receptions in each storage unit is compared with the usage frequency distribution file to determine whether the current reception status falls within the normal distribution range formed by the historical records.

[0026] When the number of receptions of a certain storage unit exceeds the upper limit of the normal distribution range in two or more consecutive transmit / receive cycles, the balance determination result is marked as an excessive reception state.

[0027] When the number of receptions of a certain storage unit is lower than the lower limit of the normal distribution range in two or more consecutive transmit / receive cycles, the balance determination result is marked as insufficient reception.

[0028] When the number of receptions for all storage units falls within the normal distribution range, the balance determination result is marked as a balanced state.

[0029] The states of receiving too much, receiving too little, and balanced are recorded together as the balance determination result.

[0030] Furthermore, when it is determined that the number of consecutive receptions in a certain storage unit exceeds the normal distribution range in the balance determination result, the output of the reception limitation instruction and the assignment of newly arriving intervals to nearby storage units include:

[0031] Suspend the receiving of newly arrived compartments in this storage unit;

[0032] The newly arrived spacer is imported into a nearby storage unit that is in a state of insufficient reception. When there are multiple nearby storage units in a state of insufficient reception, the unit with the lowest number of receptions in the historical operation record is selected.

[0033] When adjacent storage units are all in a balanced state, they are imported into adjacent storage units according to a pre-set allocation order;

[0034] When adjacent storage units are all in the state of receiving too much, the state is recorded. During the receipt stage, newly arrived spacers are temporarily suspended. When the balance determination result is updated to the state of insufficient reception or balanced state, reallocation is performed.

[0035] Furthermore, when establishing priority determination rules during the winding phase, the following are included:

[0036] The objects to be sent are classified according to the associated information, which includes path anomaly marking information, delay anomaly marking information, and balance determination results;

[0037] When a pending bar object carries a delay exception flag, the pending bar object is classified into the first priority category;

[0038] When a bar object to be sent has path exception flag information, the bar object to be sent will be classified into the second priority category;

[0039] When the object to be issued originates from a storage unit that has been marked as receiving too many states by the balance determination result, the object to be issued will be classified into the third priority category.

[0040] When the object to be sent does not have any associated information, the object to be sent will be classified into the fourth priority category;

[0041] When a bar object has different associated information at the same time, it is judged in the order of delay anomaly marker information, path anomaly marker information, and balance judgment result, and the category with the highest priority is retained for classification.

[0042] Furthermore, when several pending bar objects are determined to be in the same priority category, including:

[0043] Based on the order of timestamp information, the pending items are sent out one by one;

[0044] When multiple objects to be issued have the same timestamp information or their order cannot be distinguished, they are compared according to the usage frequency information, which is the number of times the corresponding storage unit is called in the historical operation record. Based on the number of times the storage unit where the object to be issued is located is called, the objects to be issued are issued one by one.

[0045] When neither the timestamp information nor the usage frequency information can determine the order of the objects to be sent, the situation where the order of the objects to be sent cannot be determined is recorded, and the corresponding objects to be sent are postponed to the next send / receive cycle and re-enter the priority determination.

[0046] Furthermore, when several pending message objects are postponed to the next send / receive cycle due to sequence determination, this includes:

[0047] At the end of the current sending and receiving cycle, the relevant pending message objects, along with their corresponding timestamp information, usage frequency information, and anomaly flag information, are recorded and marked as continuation objects;

[0048] When entering the next sending and receiving cycle, the objects to be sent will be imported into the priority determination process first, and will participate in the classification and order comparison at the same time as the newly generated objects to be sent.

[0049] When the order of the delayed objects cannot be determined in two send / receive cycles, the backup order rule is executed in the third send / receive cycle, and the delayed objects are sent out in the order in which the strips enter the path in the receiving phase.

[0050] Once the alternate order rule is executed, the execution result will be recorded, and the deferred flag will be removed.

[0051] Furthermore, when the deferred object enters a subsequent send / receive cycle, the status information of the deferred object is updated, including:

[0052] Update the timestamp information of the object to be sent to the starting point of the latest transmission and reception cycle;

[0053] The usage frequency information of the delayed object is cumulatively corrected, the usage frequency information is recorded during the delay period, and compared with the usage frequency information of the new object when determining priority;

[0054] The abnormal marking information of the object to be extended is corrected. When no new abnormal markings appear during the extension period, the original abnormal markings are removed.

[0055] Re-import the deferred object into the priority determination process.

[0056] Compared with existing technologies, the advantages of this invention are as follows: By acquiring the location information, movement direction information, timestamp information, usage frequency information, and anomaly marker information of the spacer during the receiving and sending process, full-process monitoring of the spacer is achieved in the receiving, temporary storage, and issuing stages. In the receiving stage, by sequentially comparing the spacer's entry path, when continuous missing location information or reversed movement direction is detected, path anomaly marker information can be obtained in a timely manner. Combined with timestamp information, it is determined whether there are consecutive arrival interval anomalies, thereby obtaining delay anomaly marker information, achieving accurate identification of anomalies in the spacer's entry process. In the temporary storage stage, by dividing the management area and defining storage units based on the spacer's arrival location information, and combining usage frequency information and historical records for balance determination, a balance determination result is obtained, and a specific storage unit is determined. When a unit receives more than the normal distribution range of consecutive receptions, it outputs a reception limit instruction, assigning newly arrived stripes to nearby storage units. Simultaneously, it can pause strip receiving when a storage unit is marked with path anomaly or delay anomaly information, and resume strip receiving when no further anomaly marking information is generated in subsequent transmission cycles, thus ensuring balance and stability during the temporary storage phase. During the striping phase, priority determination rules are established for several striping objects based on path anomaly, delay anomaly, and balance determination results. This allows for reasonable sorting of the striping process. When several striping objects are in the same priority category, they are sequentially determined according to timestamp information. If the sequential determination results are the same, the striping object is delayed to the next transmission cycle and re-enters priority determination through a deferral mechanism, thus ensuring the orderliness and continuity of the striping phase.

[0057] On the other hand, this application also provides a control system for automatic sending and receiving of spacers, for applying the above-mentioned control method for automatic sending and receiving of spacers, including:

[0058] The information acquisition module is configured to acquire location information, movement direction information, timestamp information, usage frequency information, and anomaly marker information during the interleaving transmission and reception process;

[0059] The process division module is configured to divide the intermittent sending and receiving process into a receiving stage, a temporary storage stage, and a sending stage.

[0060] The receipt determination module is configured to compare the entry path of the receipt sequentially based on the location information and the direction of movement information during the receipt stage. When the location information is continuously missing or the direction of movement is reversed, the path abnormality mark information is obtained. The module determines whether there is a continuous arrival interval abnormality based on the timestamp information. When there is a continuous arrival interval abnormality, the delay abnormality mark information is obtained.

[0061] The temporary storage management module is configured to divide management areas based on the location information when the spacer arrives during the temporary storage phase, define each management area as a storage unit, and perform balance determination based on usage frequency information and historical records to obtain the balance determination result. When it is determined that the number of consecutive receptions in a certain storage unit exceeds the normal distribution range, a reception limit instruction is output and the newly arrived spacer is assigned to a nearby storage unit. When the spacer in the storage unit is marked by path anomaly marker information or delay anomaly marker information, the storage unit is determined to be an abnormal storage unit and the reception of spacer in the storage unit is suspended. If no path anomaly marker information or delay anomaly marker information associated with the storage unit is generated in subsequent transmission and reception cycles, the suspension is lifted and the reception function of the storage unit is restored.

[0062] The winding determination module is configured to establish priority determination rules for several existing objects to be wound simultaneously during the winding stage, based on path anomaly marker information, delay anomaly marker information, and balance determination results.

[0063] The deferred processing module is configured to, when several pending message objects are determined to be in the same priority category, sequentially determine them according to the timestamp information. If several pending message objects have the same sequential determination result, the pending message objects are deferred to the next send / receive cycle and re-enter the priority determination in the subsequent send / receive cycle.

[0064] It is understandable that the aforementioned control system for automatic sending and receiving of spacers has the same beneficial effects, and will not be elaborated upon here. Attached Figure Description

[0065] Various other advantages and benefits will become apparent to those skilled in the art upon reading the following detailed description of preferred embodiments. The accompanying drawings are for illustrative purposes only and are not intended to limit the invention. Furthermore, the same reference numerals denote the same parts throughout the drawings. In the drawings:

[0067] Figure 2 This is a structural block diagram of a control system for automatic sending and receiving of spacers, provided as an embodiment of the present invention. Detailed Implementation

[0068] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features in the embodiments of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0069] In some embodiments of this application, see Figure 1 As shown, a control method for automatic sending and receiving of spacers includes:

[0070] S100: Obtain the location information, movement direction information, timestamp information, usage frequency information, and anomaly marker information of the interleaving transceiver process;

[0071] S200: Divide the inter-strip sending and receiving process into a receiving stage, a temporary storage stage, and a sending stage;

[0072] S300: During the receipt stage, the entry path of the strip is sequentially compared according to the location information and the direction of movement information. When the location information is continuously missing or the direction of movement is reversed, the path abnormality mark information is obtained. The timestamp information is used to determine whether there is a continuous arrival interval abnormality. When there is a continuous arrival interval abnormality, the delay abnormality mark information is obtained.

[0073] S400: During the temporary storage phase, the management area is divided according to the location information when the spacer arrives. Each management area is defined as a storage unit. The balance is determined based on the usage frequency information and historical records. When it is determined that the number of consecutive receptions in a certain storage unit exceeds the normal distribution range, a reception limit instruction is output and the newly arrived spacer is assigned to a nearby storage unit. When the spacer in the storage unit is marked by path abnormality marking information or delay abnormality marking information, the storage unit is determined to be an abnormal storage unit and the receiving of spacers in the storage unit is suspended. If no path abnormality marking information or delay abnormality marking information associated with the storage unit is generated in subsequent transmission and reception cycles, the suspension is lifted and the receiving function of the storage unit is restored.

[0074] S500: During the winding phase, priority determination rules are established for several concurrently existing objects to be wound based on path anomaly marking information, delay anomaly marking information, and balance determination results.

[0075] S600: When several pending message objects are determined to be in the same priority category, they are judged sequentially according to the timestamp information. If several pending message objects have the same sequential judgment result, the pending message objects are postponed to the next send / receive cycle and re-enter the priority judgment in the subsequent send / receive cycle.

[0076] Specifically, during production line operation, various types of receiving and issuing status information for the spacers are acquired. This information includes location information, movement direction information, timestamp information, usage frequency information, and anomaly marker information. Location information reflects the spatial position of the spacer along its operating path; movement direction information determines whether the spacer's movement conforms to a preset path direction; timestamp information records the order in which the spacers enter each stage; usage frequency information reflects the calling characteristics of each storage unit in historical operation; and anomaly marker information identifies abnormal situations detected during operation. Subsequently, the spacer receiving and issuing process is divided into three parts: the receiving stage, the temporary storage stage, and the issuing stage, to achieve segmented control. During the receipt stage, the system compares the position information of the spacer with the preset path information segment by segment, and compares the movement direction information with the preset direction information one by one. When the missing position information is detected in the continuous collection points, or when the movement direction is opposite to the preset direction in the adjacent collection points, it can be determined that there is an anomaly in the entry path of the spacer and generate path anomaly mark information. At the same time, by comparing the arrival timestamps of the spacers, if the time interval between two adjacent spacers exceeds the normal reference range formed by the historical operation records, and repeats in subsequent comparisons, it is identified as a continuous arrival interval anomaly and a delay anomaly mark information is generated. During the temporary storage phase, the system divides management areas based on the location information of the arrival of the spacer strips. Each area is defined as a storage unit. A usage frequency distribution file for each storage unit is established by combining usage frequency information and historical operation records. Balance is determined by comparing the current number of receptions with the normal distribution range. If the number of receptions in a storage unit is higher than the upper limit of the normal distribution range in a continuous cycle, it is determined to be in an over-reception state, and a reception limitation instruction is output, guiding newly arriving spacers to nearby storage units. If the number of receptions in a storage unit is lower than the lower limit in a continuous cycle, it is determined to be in an under-reception state, and new arriving spacers are preferentially imported into it. When a spacer strip in a storage unit is marked with path anomaly or delay anomaly information, the storage unit is determined to be an abnormal storage unit, and its receiving function is suspended until no new anomaly markers are generated in subsequent transmission and reception cycles. Finally, in the springing phase, the system establishes priority determination rules based on path anomaly, delay anomaly, and balance determination results. Different objects to be springed are classified into different priority categories according to their associated information to ensure that abnormal spacers are processed first and to maintain overall balance. When several pending message objects are in the same priority category, the system first determines the order of sending based on the timestamp information. If, after the order determination, there are still multiple pending message objects whose order cannot be distinguished, then these pending message objects are marked as deferred objects and deferred to the next send / receive cycle to re-enter the priority determination process.Through the above steps, the entire process of receiving, temporarily storing, and issuing the strips is made traceable, manageable, and controllable, thereby significantly improving production efficiency and automation level while ensuring distribution accuracy.

[0077] Understandably, by introducing information collection, stage division, and multi-level judgment mechanisms into the transmission and reception process of the spacers, orderly management of the spacers throughout the entire process of receiving, temporarily storing, and issuing is achieved. By comparing the order of position information and movement direction information, anomalies such as missing paths and reversed directions are identified and marked in a timely manner, preventing spacers from being misaligned or blocked in the transmission stage. By comparing arrival intervals using timestamp information, delays and backlogs can be captured, ensuring the uniformity of the transmission and reception rhythm. Furthermore, by establishing a balance judgment based on usage frequency and historical records in the temporary storage stage, the reception volume of each storage unit can be dynamically balanced, preventing individual units from being over-concentrated or idle for a long time. At the same time, when a storage unit is marked with an anomaly, it is paused and isolated in a timely manner, ensuring the overall stability of the system. Finally, in the issuing stage, a multi-level priority judgment rule is constructed, so that spacers with anomaly marks or in an unbalanced state are processed first, and similar conflicts are resolved by joint judgment of timestamp and usage frequency information. When the order still cannot be distinguished, a delay mechanism and a backup order rule are introduced, thereby ensuring that all spacers can be issued in an orderly manner in the end. Therefore, this invention automates the receiving and dispatching of spacers while ensuring the reliability, balance, and flexibility of the process. It can replace manual operation and improve the overall efficiency and intelligence level of aluminum profile production lines.

[0078] In some embodiments of this application, when performing a sequential comparison of the entry path of the spacer based on location information and movement direction information, the following is included:

[0079] Preset path and preset direction information are obtained based on historical operation records;

[0080] The position information of the spacer during the sending and receiving process is matched with the preset path information segment by segment, and the movement direction information of the spacer is compared with the preset direction information one by one;

[0081] When location information is missing from the preset path information, record the missing segment;

[0082] When the direction of motion information is opposite to the preset direction information, record the reversed segment;

[0083] When the number of consecutive occurrences of missing segments exceeds the preset judgment threshold, or when the movement direction information is detected to be opposite to the preset direction information at adjacent collection points, it is determined that there is an anomaly in the entry path of the partition, the path anomaly marker information is obtained, and the path anomaly marker information and the corresponding partition are recorded. The preset judgment threshold is obtained based on the statistical results of historical operation records.

[0084] Specifically, the process begins by establishing preset path and direction information for the spacer under normal transmission and reception conditions based on historical operation records. Position and direction information of the spacer during long-term operation are then collected to form a continuous trajectory dataset. This trajectory data is then cleaned and categorized to eliminate abnormal fluctuations or occasional interference, extracting the trajectory patterns and direction regularities of the spacer under normal conditions in most cycles. Based on this, the typical position coordinate range and corresponding direction of movement for each path segment are statistically analyzed. These frequently occurring trajectory segments that conform to stable patterns are summarized as preset path information, and their corresponding directions are summarized as preset direction information. The preset path information describes the path segments the spacer should traverse sequentially during operation, while the preset direction information describes the direction of movement the spacer should maintain within these path segments. Together, they constitute the reference standard for judgment. During actual reception, the spacer's position information is collected, and the collected position information is compared segment by segment with the preset path information to determine whether the spacer is moving along the preset trajectory. Simultaneously, the spacer's direction of movement information is collected and compared one by one with the preset direction information to confirm whether the spacer's direction of movement is consistent with the normal direction. When the position information of the spacer is not found in the preset path information during the comparison process, it is recorded as a missing segment, indicating that the spacer has deviated from the preset path at that position. When the movement direction of the spacer is continuously detected to be opposite to the preset direction at adjacent sampling points, it is recorded as a reverse segment, indicating that the spacer has deviated in the opposite direction of movement. As the comparison process continues, the number of times the missing segment appears is counted. When the number of consecutive occurrences of the missing segment exceeds the preset judgment threshold obtained from the statistics of historical operation records, it indicates that the deviation of the spacer on the path has exceeded the allowable range, and it is necessary to determine that there is an anomaly in the spacer's entry into the path. The preset judgment threshold needs to extract the path data under normal operation from no less than one hundred historical transmission and reception cycles (if less than 100, it is calculated based on the maximum number of cycles), and record the sampling point sequence of position information and the corresponding movement direction information for each segment. Then, in each cycle, two values ​​are calculated: one is the maximum number of consecutive missing position information, and the other is the maximum number of consecutive cycles with the movement direction opposite to the preset direction. These values ​​are formed into two sample sets. Next, the distribution statistics of these two sample sets are performed to obtain the frequency distribution curve, and the statistical value of the 95th percentile is used as the threshold benchmark. For example, in samples with missing location information, if 95% of the cycles have no more than two consecutive missing occurrences, the threshold is set to three. In samples with opposite directions, if 95% of the cycles have no more than one consecutive reversal, the threshold is set to two. In this case, the meaning of the judgment threshold is: when, in actual operation, there are three or more consecutive missing location information occurrences, or two or more consecutive reversals, it is directly judged as a path anomaly, and path anomaly marker information is generated.If the sampling frequency differs from historical statistics, it is converted according to the proportion of sampling points. For example, if the current sampling frequency is 50% higher than the historical statistical frequency, the original threshold is multiplied by 1.5 and rounded up to ensure that the judgment criteria remain consistent under different sampling conditions. Through this method based on a clearly defined sample size, distribution statistics, and quantile calculation, the preset judgment threshold can be accurately established before operation and used in subsequent transmission and reception processes. Similarly, when the movement direction is continuously detected to be opposite to the preset direction at adjacent sampling points, it indicates that the movement state of the spacer has seriously deviated from normal conditions. At this time, path anomaly marker information is generated and bound to the corresponding spacer for identification and classification in subsequent temporary storage and transmission stages. By establishing preset reference standards, comparing segment by segment and point by point, and conducting continuous anomaly statistics, abnormal situations in the spacer's entry into the path can be detected, and traceable path anomaly marker information can be formed, thereby ensuring the stability and controllability of the spacer's transmission and reception process.

[0085] In some embodiments of this application, determining whether there is an abnormal consecutive arrival interval based on timestamp information includes:

[0086] Based on the distribution of arrival timestamps of the intervals under normal operating conditions in the historical operation records, the reference range for consecutive arrival intervals is determined;

[0087] The actual arrival timestamp of each interval is calculated by comparing it with the actual arrival timestamp of the previous interval to obtain the time interval between the arrival of the two intervals, and the time interval is compared with the reference range obtained from historical operation records.

[0088] When a single time interval exceeds the reference range, an abnormal interval is recorded.

[0089] When an abnormal interval appears in two or more consecutive comparison results, it is determined to be a continuous arrival interval anomaly, and the delay anomaly marker information is obtained.

[0090] Specifically, the first step is to statistically analyze the arrival timestamps of adjacent bays in historical operation records during normal operation to determine the actual arrival intervals between them, thus constructing a continuous arrival interval range. This range can be determined by calculating the mean and dispersion of historical arrival interval data. For example, using the mean as the center, an upper and lower interval can be set based on the statistical results, ensuring that the vast majority of normal arrival intervals fall within this range, thus forming a reference standard. During actual operation, the actual arrival timestamp of each bay is collected sequentially and the difference is calculated with the actual arrival timestamp of the previous bay to obtain the actual arrival interval between the two bays. This actual arrival interval is then compared with the historically obtained continuous arrival interval range. When an actual arrival interval exceeds the continuous arrival interval range, it is recorded as an abnormal interval. As the comparison continues, if abnormal intervals are detected in two or more consecutive comparisons, it indicates that the arrival process of the bays has encountered a stability problem, is determined to be a continuous arrival interval anomaly, and a delay anomaly marker is generated. Simultaneously, the delay anomaly marker is linked to the corresponding bay's record. By establishing a continuous arrival interval range based on historical data and combining it with real-time comparison, it can be ensured that the anomaly detection results have statistical basis and operability.

[0091] In some embodiments of this application, when determining the balance based on usage frequency information and historical records, the following methods are included:

[0092] During the temporary storage phase, usage frequency information for each storage unit is collected, and usage frequency distribution files for each storage unit are constructed based on historical operation records.

[0093] The number of receptions in each storage unit is compared with the frequency distribution file to determine whether the current reception falls within the normal distribution range formed by the historical records.

[0094] When the number of receptions of a certain storage unit exceeds the upper limit of the normal distribution range in two or more consecutive transmit / receive cycles, the balance determination result is marked as an over-reception state.

[0095] When the number of receptions of a certain storage unit is lower than the lower limit of the normal distribution range in two or more consecutive transmit / receive cycles, the balance determination result is marked as insufficient reception.

[0096] When the number of receptions for all storage units falls within the normal distribution range, the balance determination result is marked as balanced.

[0097] The states of receiving too much, receiving too little, and balanced are recorded together as the balance determination result.

[0098] Specifically, during the temporary storage phase, usage frequency information for each storage unit is first collected. Usage frequency information indicates the number of times a storage unit receives or calls a spacer within a certain time frame. Based on historical operation records, the reception status of each storage unit is statistically analyzed to create a usage frequency distribution file. This file reflects the reception patterns exhibited by the storage unit over long-term operation, and a normal distribution range is determined based on this. The normal distribution range is defined by statistically analyzing the concentrated range of reception counts across most cycles, thereby establishing upper and lower limits. For example, if historical statistics show that a storage unit's reception counts across most cycles are concentrated between 10 and 20, then 10 to 20 can be defined as the normal distribution range, with more than 20 counts considered excessive reception and less than 10 counts considered insufficient reception. In actual operation, the number of receptions for each storage unit in the current cycle is compared one by one with the normal distribution range in the frequency distribution file. When the number of receptions for a storage unit in two or more consecutive transmit / receive cycles is higher than the upper limit of the normal distribution range (e.g., more than 25 times in two consecutive cycles), the balance determination result is marked as "over-reception". When the number of receptions for a storage unit in two or more consecutive transmit / receive cycles is lower than the lower limit of the normal distribution range (e.g., less than 8 times in two consecutive cycles), the balance determination result is marked as "under-reception". When the number of receptions for all storage units is within the normal distribution range, the balance determination result is marked as "balanced". In some cases, if only one transmit / receive cycle's data is available for determination, a conclusion of over-reception or under-reception is not directly generated. Instead, the result of that cycle is temporarily recorded as reference data. Only after the next transmit / receive cycle arrives is it compared with continuous data and a comprehensive judgment made to ensure the stability and reliability of the balance determination result. This dynamic judgment method based on statistical results can clearly distinguish between three states: excessive reception, insufficient reception, and balanced reception. This avoids the storage unit from receiving unlimited data in actual operation and also prevents misjudgments caused by single-cycle fluctuations.

[0099] In some embodiments of this application, when it is determined that the number of consecutive receptions in a storage unit exceeds the normal distribution range in the balance determination result, outputting a reception limitation instruction and assigning newly arriving spacers to nearby storage units includes:

[0100] Suspend the receiving of newly arrived compartments in this storage unit;

[0101] The newly arrived spacer is imported into a nearby storage unit that is in a state of insufficient reception. When there are multiple nearby storage units in a state of insufficient reception, the unit with the lowest number of receptions in the historical operation record is selected.

[0102] When adjacent storage units are all in a balanced state, they are imported into adjacent storage units according to a pre-set allocation order;

[0103] When adjacent storage units are all in the state of receiving too much, the state is recorded. During the receipt stage, newly arrived spacers are temporarily suspended. When the balance determination result is updated to the state of insufficient reception or balanced state, reallocation is performed.

[0104] Specifically, when it is determined that the number of receptions of a certain storage unit continuously exceeds the normal distribution range in the balance determination results over multiple consecutive transmit / receive cycles, a reception limit instruction is first issued to that storage unit. The purpose of the reception limit instruction is to suspend the storage unit from receiving newly arriving slots, thereby preventing the storage unit from experiencing continuous overload. Subsequently, newly arriving slots need to be reallocated based on the status of adjacent storage units. When there are adjacent storage units in a state of insufficient reception, newly arriving slots are preferentially introduced to adjacent storage units in a state of insufficient reception to balance the overall storage load; when there are multiple adjacent storage units in a state of insufficient reception, the storage unit with the lowest cumulative number of receptions is selected as the import target based on the comparison results of reception counts in historical operation records to avoid long-term underutilization of some storage units. When all adjacent storage units are in a balanced state, the allocation no longer relies on real-time status, but instead imports newly arriving slots sequentially according to a pre-set allocation order. The pre-set allocation order is determined during system initialization or long-term operation based on the production line layout, spatial relationships between storage units, physical order of equipment transmission paths, and average allocation in historical operation records. For example, it can be set from left to right or top to bottom, or it can be weighted according to the average number of receptions per storage unit in historical records, forming a fixed sequence rule. This ensures that even when adjacent storage units are in a balanced state, the spacers can still be allocated in a regular manner, avoiding arbitrariness in the allocation process. When all adjacent storage units are in an over-reception state, it indicates that the entire temporary storage area is overloaded. In this case, the spacer is not directly imported into any storage unit; instead, this state is recorded, and newly arrived spacers are temporarily deferred during the receiving stage. Deferred spacers are in a pending allocation state until subsequent balance determination results show that some storage units have recovered to an under-reception state or a balanced state. Then, the deferred spacers are re-imported to achieve dynamic repair and load balancing of the overall scheduling. The above allocation logic ensures the rationality and consistency of the storage unit allocation path under different operating conditions, avoiding long-term overload or long-term idleness of certain units.

[0105] In some embodiments of this application, establishing priority determination rules during the winding phase includes:

[0106] The objects to be sent are classified according to the associated information, which includes path anomaly marker information, delay anomaly marker information, and balance determination results;

[0107] When a pending bar object carries a delay exception flag, the pending bar object is classified into the first priority category;

[0108] When a bar object to be sent has path exception flag information, the bar object to be sent will be classified into the second priority category;

[0109] When the object to be issued originates from a storage unit that has been marked as receiving too many states by the balance determination result, the object to be issued will be classified into the third priority category.

[0110] When the object to be sent does not have any associated information, the object to be sent will be classified into the fourth priority category;

[0111] When a bar object has different associated information at the same time, it is judged in the order of delay anomaly marker information, path anomaly marker information, and balance judgment result, and the category with the highest priority is retained for classification.

[0112] Specifically, the first step is to screen the send / receive status information of all pending message objects and classify them based on the associated information they carry. This associated information includes path anomaly markers, delay anomaly markers, and balance assessment results. This information reflects any anomalies in the preceding stages and the state of the storage environment of the pending message objects. When a pending object carries a delay anomaly flag, it indicates a persistent deviation in the arrival interval during the receiving phase. To prevent further backlog or disruption of subsequent operations due to delays, it is prioritized and placed in the first priority category to ensure earliest dispatch. When a pending object carries a path anomaly flag, it indicates an anomaly in its entry path, such as continuous missing position information or reversed movement direction. Failure to address this promptly could cause path confusion in subsequent operations, thus placing it in the second priority category. When a pending object originates from a storage unit marked as overloaded in the balance assessment results, it indicates that the unit's load is already high. To achieve overall balance, such objects should be prioritized for dispatch to reduce unit pressure, thus placing it in the third priority category. When a pending object does not carry any anomaly or balance information, it is considered to be in a normal state and is placed in the fourth priority category, dispatched in the normal order unless otherwise specified. In some cases, a springing object may possess multiple associated information simultaneously. For example, it may carry both delay anomaly markers and originate from a storage unit that receives too many states. To avoid conflicts, a judgment order needs to be set during classification. The classification should prioritize delay anomaly markers over path anomaly markers, and path anomaly markers over balance judgment results, filtering step-by-step, ultimately retaining the highest priority category. This priority-based classification and conflict resolution based on different types of associated information ensures the orderliness and rationality of the springing process, reducing the overall operational efficiency decline caused by the retention of abnormal objects or the continuous accumulation of unbalanced units.

[0113] In some embodiments of this application, when several pending bar objects are determined to be in the same priority category, the following is included:

[0114] Based on the order of timestamp information, the pending items are sent out one by one;

[0115] When multiple objects to be issued have the same timestamp information or their order cannot be distinguished, they are compared based on usage frequency information, which is the number of times the corresponding storage unit is called in the historical operation record. Based on the number of times the storage unit where the object to be issued is located is called, the objects to be issued are issued one by one.

[0116] When neither the timestamp information nor the usage frequency information can determine the order of the objects to be sent, the situation where the order of the objects to be sent cannot be determined is recorded, and the corresponding objects to be sent are postponed to the next send / receive cycle and re-enter the priority determination.

[0117] Specifically, timestamp information reflects the arrival order of spacers during the sending and receiving process. Therefore, under the same priority category, spacers with earlier timestamps are sent first to ensure that the overall processing follows the first-in, first-out (FIFO) logic. When multiple spacers have the same timestamp or their order cannot be distinguished within the recording precision range, usage frequency information is introduced as a further criterion. Usage frequency information comes from the number of times the corresponding storage unit is called in the historical operation record, reflecting the usage intensity of a storage unit in the overall operation. When the timestamps of multiple spacers cannot be distinguished, spacers from storage units with higher call counts are sent first to avoid the accumulation of spacers in high-frequency units, thereby maintaining the balance of the overall operation. When neither timestamp information nor usage frequency information can determine the sending order, such as when two or more spacers have the same timestamp and the usage frequency information of their corresponding storage units is consistent, it is considered a conflict situation where the order cannot be determined. In this case, instead of forcibly determining the order of winding, these objects to be wound are uniformly recorded as deferred objects, and their timestamp information, usage frequency information and abnormality marker information are marked in the record. After the current sending and receiving cycle ends, they are deferred to the next sending and receiving cycle and re-participated in the classification and comparison in the new round of priority determination process to ensure the fairness and traceability of the winding process.

[0118] In some embodiments of this application, when a plurality of pending message objects are postponed to the next transmission / reception cycle due to sequence determination, the following is included:

[0119] At the end of the current sending and receiving cycle, the relevant pending message objects, along with their corresponding timestamp information, usage frequency information, and anomaly flag information, are recorded and marked as continuation objects;

[0120] When entering the next sending and receiving cycle, the objects to be sent will be imported into the priority determination process first, and will participate in the classification and order comparison at the same time as the newly generated objects to be sent.

[0121] When the order of the delayed objects cannot be determined in two send / receive cycles, the backup order rule is executed in the third send / receive cycle, and the delayed objects are sent out in the order in which the strips enter the path in the receiving phase.

[0122] Once the alternate order rule is executed, the execution result will be recorded, and the deferred flag will be removed.

[0123] Specifically, the recorded information includes the identifier of the object to be sent, its corresponding timestamp, usage frequency, and anomaly flags, ensuring that its state and characteristics are fully preserved in subsequent sending and receiving cycles. At the end of the current sending and receiving cycle, these deferred objects are explicitly marked and archived. Upon entering the next sending and receiving cycle, deferred objects are prioritized in the priority determination process, where they are simultaneously classified and compared in order with newly generated objects to be sent, ensuring that deferred objects do not remain indefinitely due to conflicts. If the sending order of deferred objects cannot be determined by comparing timestamp and usage frequency information within two consecutive sending and receiving cycles, a backup order rule is triggered in the third sending and receiving cycle to prevent long-term backlog from affecting the overall process. The backup order rule is based on the entry path order of the deferred objects during the receiving stage, prioritizing the deferred objects that entered the path first, thus providing a workable solution in special circumstances. After the backup order rule is executed, its results are recorded in detail, including the actual sending order and related comparison information, and the deferred flag is removed, preventing these objects from participating in the priority determination of subsequent cycles as deferred objects.

[0124] In some embodiments of this application, when the deferred object enters a subsequent transmit / receive cycle, the status information of the deferred object is updated, including:

[0125] Update the timestamp information of the object to be sent to the starting point of the latest transmission and reception cycle;

[0126] The usage frequency information of the delayed object is cumulatively corrected, the usage frequency information is recorded during the delay period, and compared with the usage frequency information of the new object when determining priority;

[0127] The abnormal marking information of the object to be extended is corrected. When no new abnormal markings appear during the extension period, the original abnormal markings are removed.

[0128] Re-import the deferred object into the priority determination process.

[0129] Specifically, before the deferred object is imported into the subsequent transmission cycle, its status information is first updated to ensure that it is on the same reference basis as the newly generated pending strip object in the new judgment process. The timestamp information of the deferred object no longer uses the record of the original transmission cycle, but is updated to the starting reference of the latest transmission cycle, thereby avoiding the impact of outdated timestamps on the accuracy of sequence determination. Regarding usage frequency information, the usage frequency of the deferred object is cumulatively corrected. The cumulative correction method is to first read the usage frequency record of the deferred object before it was deferred, which reflects the number of times the storage unit where the deferred object is located was called in the historical operation; then, during the deferred period, the number of times the storage unit is called in each transmission cycle is continued to be counted, and these call counts are summed one by one to form a cumulative value including historical calls and calls during the deferred period. This cumulative value is used as the corrected usage frequency information, thereby ensuring that the usage frequency of the deferred object can truly reflect its call situation during the retention phase. Regarding anomaly marking information, the anomaly marking information of the delayed object is corrected. The correction method is to check whether the delayed object had path anomaly marking information or delay anomaly marking information before being delayed. When the delayed object enters a subsequent sending and receiving cycle, its receipt and temporary storage process during the delay period is checked. If no new path anomaly marking information or delay anomaly marking information associated with the delayed object appears in several consecutive sending and receiving cycles, the original anomaly marking is removed during the update process, and the status of the delayed object is restored to normal. If new path anomaly marking information or delay anomaly marking information is detected again during the delay period, it is retained during the update and recorded overlaid with the original anomaly marking information to ensure that the anomaly history and latest status of the delayed object can be fully reflected when determining priority. After the above-mentioned update of timestamp information, cumulative correction of usage frequency information, and correction of anomaly marking information, the delayed object is re-introduced into the priority determination process and participates in classification and comparison together with newly generated objects to be sent, thereby ensuring the continuity, accuracy, and fairness of the sending process.

[0130] In another preferred embodiment based on the above embodiments, see [reference] Figure 2 As shown, this embodiment provides a control system for automatic sending and receiving of spacers, including:

[0131] The information acquisition module is configured to acquire location information, movement direction information, timestamp information, usage frequency information, and anomaly marker information during the interleaving transmission and reception process;

[0132] The process division module is configured to divide the intermittent sending and receiving process into a receiving stage, a temporary storage stage, and a sending stage.

[0133] The receipt determination module is configured to compare the entry path of the receipt sequentially based on the location information and the direction of movement information during the receipt stage. When the location information is continuously missing or the direction of movement is reversed, the path abnormality mark information is obtained. The module determines whether there is a continuous arrival interval abnormality based on the timestamp information. When there is a continuous arrival interval abnormality, the delay abnormality mark information is obtained.

[0134] The temporary storage management module is configured to divide management areas based on the location information when the spacer arrives during the temporary storage phase, define each management area as a storage unit, and perform balance determination based on usage frequency information and historical records to obtain the balance determination result. When it is determined that the number of consecutive receptions in a certain storage unit exceeds the normal distribution range, a reception limit instruction is output and the newly arrived spacer is assigned to a nearby storage unit. When the spacer in the storage unit is marked by path anomaly marker information or delay anomaly marker information, the storage unit is determined to be an abnormal storage unit and the reception of spacer in the storage unit is suspended. If no path anomaly marker information or delay anomaly marker information associated with the storage unit is generated in subsequent transmission and reception cycles, the suspension is lifted and the reception function of the storage unit is restored.

[0135] The winding determination module is configured to establish priority determination rules for several existing objects to be wound simultaneously during the winding stage, based on path anomaly marker information, delay anomaly marker information, and balance determination results.

[0136] The deferred processing module is configured to, when several pending message objects are determined to be in the same priority category, sequentially determine them according to the timestamp information. If several pending message objects have the same sequential determination result, the pending message objects are deferred to the next send / receive cycle and re-enter the priority determination in the subsequent send / receive cycle.

[0137] Understandably, the information acquisition module collects basic data during the sending and receiving process of the spacer, ensuring comprehensive coverage of location information, movement direction information, timestamp information, usage frequency information, and anomaly marker information, providing a reliable basis for subsequent judgment and scheduling. The process division module rationally divides the entire sending and receiving process into a receiving stage, a temporary storage stage, and a sending stage, enabling the control logic of different stages to be executed independently and form a hierarchical connection, avoiding logical confusion or scheduling conflicts between different links. The receiving judgment module, through path sequence comparison and time interval analysis, can promptly identify missing, reversed, or delayed anomalies in the spacer's entry process and generate corresponding marker information, realizing early warning and recording of early operational anomalies. The temporary storage management module, through management area division and balance judgment, can not only determine the receiving process but also... The system dynamically adjusts the state of storage units based on frequency and historical distribution, and can also output limited-receive instructions for units that continuously exceed limits, allocating newly arriving spacers to nearby storage units to avoid overload in a single area. Simultaneously, it pauses and resumes storage units with abnormal markers, ensuring the stability and flexibility of the temporary storage process. The spring determination module establishes priority classification rules, achieving hierarchical scheduling based on delay anomalies, path anomalies, and balance status. This prioritizes abnormal spacers and heavily loaded units, while normal objects are orderly moved to lower priority categories, ensuring the safety and continuity of the spring-spinning process. The deferred processing module provides fault tolerance and remedial measures for situations where timestamps and usage frequencies cannot distinguish order, allowing objects to be springed to participate in determination again in subsequent receiving and sending cycles, avoiding stagnation or omissions caused by determination conflicts. This invention achieves closed-loop control of the entire process—information collection, anomaly identification, dynamic scheduling, and fault-tolerant processing—ensuring the efficiency, stability, and traceability of spacers in the automatic receiving and sending process. It can replace manual operation and improve the automation and intelligence level of aluminum profile production processes.

[0138] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of the present invention. Any modifications or equivalent substitutions that do not depart from the spirit and scope of the present invention should be covered within the protection scope of the claims of the present invention.
