[0002] The surface treatment of galvanized steel sheets is a step to improve their corrosion resistance and processing performance, which mainly includes three stages: pretreatment, galvanizing and post-treatment. Among them, pretreatment is to remove dirt, grease and oxides on the surface of the steel sheet to ensure that the galvanized layer can firmly adhere to the surface of the steel sheet. Galvanizing is to form a dense zinc layer on the surface of the steel sheet to prevent the steel sheet from being corroded. After galvanizing, the galvanized steel sheet needs to be cut, punched, bent and other processes according to the specific needs of the product.

[0003] In the related art, the construction of the process route for surface treatment of galvanized steel sheets lacks systematicity, and the treatment process cannot be clearly decomposed into surface treatment steps, resulting in unclear process relationships between steps and ineffective execution. Moreover, in the related art, when executing the process route, once an abnormality or failure occurs, the equipment operation is stopped. If the production interruption is caused by an occasional failure, it will affect the production rhythm of the surface treatment of galvanized steel sheets and reduce the efficiency of the surface treatment of galvanized steel sheets.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1 The figure is a flow chart of a method for monitoring the surface treatment process of a galvanized steel sheet in a specific embodiment, the method comprising: S101, obtaining a surface treatment process route from a database, parsing the surface treatment process route, and determining execution instructions for each device and a process equipment instruction set.

[0031] The surface treatment process route is to construct the galvanized steel plate surface treatment process according to the equipment execution instructions in all the processing steps of the surface treatment process and to run the surface treatment process.

[0032] The database is used to store the components needed in the surface treatment process. The surface treatment process route is pre-stored in the database. The surface treatment process route has the equipment execution instructions in all the processing steps of the surface treatment process and the surface treatment process is pre-constructed to construct the galvanized steel plate surface treatment process.

[0033] In this embodiment, the equipment execution instructions in all the processing steps of the surface treatment process can be used as surface treatment steps, and the running surface treatment processes between each equipment execution instruction can be used as the process relationship between the surface treatment steps to construct the surface treatment process of the galvanized steel plate. Constructing the surface treatment process of the galvanized steel plate can visualize the various processing steps of the surface treatment process, and can change the process relationship between the surface treatment steps to adaptively adjust the running surface treatment process of the equipment execution instruction. The surface treatment process route contains the equipment execution instructions corresponding to all the processing steps corresponding to the surface treatment process, and the process equipment instruction set that needs to be executed when executing each equipment execution instruction. The process equipment instruction set is a process instruction that calls the corresponding surface treatment automation operation program to realize the equipment execution instruction processing.

[0034] S102. According to the surface treatment status of the actual surface treatment process, the equipment execution instructions in the surface treatment process route are adjusted to obtain equipment execution instructions executed in the order of the surface treatment process of the galvanized steel plate.

[0035] In this embodiment, the surface treatment state of the actual surface treatment process may involve corrosion resistance, surface roughness, etc., and the user may manually adjust the device execution instruction according to the current surface treatment process. Since only some processing steps are partially added or reduced, or process parameters are changed, there is no need to re-edit the process, which can improve the adjustment efficiency.

[0036] For example, it may also involve adding or reducing certain processing steps, or changing process parameters. For example, if the order requires higher corrosion resistance, it is necessary to increase the passivation treatment time or adjust the formula of the passivation solution, and adjust the execution instructions of the passivation equipment accordingly.

[0037] The database of this embodiment can collect and organize the relevant knowledge and experience of various galvanized steel plate surface treatment processes, including the characteristics of different treatment processes, applicable equipment types, process parameter ranges, etc., to establish a process knowledge base. The knowledge base stores a large number of standard process routes and corresponding equipment execution instruction templates.

[0038] This embodiment can match the existing surface treatment process in the database to the actual surface treatment process. Specifically, a deep learning algorithm, such as a neural network, can be used to train a large number of existing surface treatment process routes and equipment execution instruction data. Let the algorithm learn the mapping relationship between the process route and the equipment execution instruction and establish a model. When a new surface treatment process route is input, the model can automatically predict and match the corresponding equipment execution instruction based on the learned knowledge.

[0039] For example, the input surface treatment process route is feature extracted to analyze key information in the process route, such as the name of the treatment process, process parameter requirements, etc. These features are then matched with the templates in the process knowledge base to find the most similar standard process route and the corresponding equipment execution instruction template, thereby automatically matching the appropriate equipment execution instruction.

[0040] S103, executing equipment execution instructions in the order of surface treatment processes to control the operation of the treatment equipment.

[0041] In this embodiment, the equipment execution instructions are executed in the order of the surface treatment processes, and the process instructions of the automatic operation program corresponding to each equipment execution instruction are respectively executed in the order of the surface treatment processes to execute the equipment execution instructions in the order of the surface treatment processes.

[0042] Among them, the surface treatment automation operation program is a program that executes the corresponding equipment execution instructions. Executing the surface treatment automation operation program can realize the processing of equipment execution instructions. Process instructions are process instructions executed in conjunction with the automation operation program. By executing commands in the order of surface treatment processes, it can be ensured that the equipment execution instructions are executed in the normal order.

[0043] S104. During the execution process, if the device execution instruction fails to execute, the device execution instruction is repeatedly executed; if the number of times the device execution instruction is repeatedly executed reaches a first preset number, the name of the device execution instruction that failed to execute and the processing device corresponding to the instruction are recorded.

[0044] For example, if there is a failure in the execution of the device execution instruction during the process of the device executing the instruction, in order to verify whether the failure of the device execution instruction is accidental, the device execution instruction can be repeatedly executed to determine whether the surface treatment of the galvanized steel plate can be completed when the device execution instruction is repeatedly executed. If the surface treatment of the galvanized steel plate can be completed, it means that the last failure of the device execution instruction was accidental. If the device execution instruction still fails when it is repeatedly executed, the device execution instruction is continued to be repeatedly executed until the number of repeated executions reaches the first preset number of times, but the device execution instruction still fails to execute, then it is confirmed that the device execution instruction cannot be executed normally, and the name of the device execution instruction that failed to execute and the processing device corresponding to the instruction can be recorded for the convenience of user inspection.

[0045] As an embodiment of the present application, if the device execution instruction fails, the device execution instruction is repeatedly executed, and the probability of successful execution of a single instruction is defined as p, and the probability of failure is defined as ; If the instruction is executed repeatedly N times, the probability of failure in all N times is:

[0046] When P fail When it is lower than the preset threshold α, it is determined to be a systemic failure; at this time, the maximum number of retries N is derived: .

[0047] Through the probability model , within the preset number of times N, the success probability p of occasional failure is higher, P fail It approaches zero quickly, which can effectively avoid misjudgment. The p of a systematic fault (such as equipment damage) is extremely low, P fail Close to 1, it can reliably trigger recording.

[0048] It can be seen that this embodiment avoids production interruptions caused by occasional failures through an automatic retry mechanism. By recording the fault instruction name and device information, the common characteristics of the faulty device, such as model and usage time, can be obtained. This embodiment can adapt to different scenarios by adjusting N and α. For example, set N=3 for fast response. In order to meet high stability requirements, set N=10 to reduce the false alarm rate.

[0049] The probability p of a single instruction being successfully executed can be obtained by the following method. By collecting a large number of records of the same or similar surface treatment equipment executing the same or similar instructions during the past surface treatment of galvanized steel sheets. For example, if a certain surface treatment equipment has successfully executed a certain instruction 950 times out of the past 1000 times, then the probability of successful execution of the instruction can be preliminarily estimated to be p=950\1000=0.95.

[0050] Considering that different production batches, equipment status, raw materials and other factors may affect the success rate of instruction execution, historical data can be classified and counted. For example, according to different equipment models, different production time periods, different raw material suppliers and other dimensions, the probability of successful instruction execution under various conditions can be calculated separately to more accurately grasp the value of p. For example, when galvanized steel plate surface treatment equipment A uses raw material A, the probability of successful instruction execution is 0.98, while when using raw material B, the probability of success is 0.93.

[0051] It should be noted that the probability of successful execution of instructions is calculated based on the design specifications, technical parameters and theoretical operating principles of the surface treatment equipment. For example, the mechanical transmission accuracy of the galvanized steel plate surface treatment equipment, the response speed and accuracy of the control system, the reliability of electrical components and other parameters can be used to derive the probability of successful execution of instructions under ideal conditions through the above mathematical model. Assuming that the failure rate of key components of a certain equipment follows the Poisson distribution, based on parameters such as its average failure interval time, the probability of normal operation of the equipment during the execution of an instruction can be calculated, and then combined with the situation of other components, the probability of successful execution of the instruction p can be comprehensively obtained.

[0052] In some embodiments, a preset number of previous step execution instructions of the device execution instruction that failed to execute are determined based on the recorded name of the device execution instruction that failed to execute and the processing device corresponding to the instruction; wherein the previous step execution instruction is a device execution instruction that needs to be executed before the device execution instruction that failed to execute.

[0053] Starting from the preset number of previous step execution instructions, re-execute the execution instructions of each device, and determine whether the device execution instruction that failed to execute has completed the surface treatment of the galvanized steel plate; if the surface treatment of the galvanized steel plate is completed, continue to execute the downstream device execution instruction; if the execution fails and the number of repeated executions reaches the second preset number, the user is prompted.

[0054] It should be noted that the maximum number of retries, the first preset number of retries, and the second preset number of retries are all intended to determine the retry limit allowed when the instruction execution fails.

[0055] In actual use, the maximum number of retries will be set to a value equal to or close to the first preset number of times to ensure that the failure of instruction execution is judged to be accidental or inevitable within a certain retry range. If the first preset number of times is set too low, some accidental failures may be misjudged as systemic failures; if it is set too high, it will increase processing time and cost.

[0056] Generally speaking, the second preset number of times is used in different judgment conditions, in coordination with the maximum number of retries and the first preset number of times, to more comprehensively and meticulously monitor and process the execution of instructions by the device.

[0057] The first preset number of times is obtained based on experience and historical data. By analyzing the failure of the equipment to execute instructions in the past galvanized steel plate surface treatment process, the average number of failures of different types of instructions and the range of common accidental failures are counted, and a reasonable first preset number is determined on this basis. For example, if historical data shows that most accidental failures can be successfully executed within 3 retries, then the first preset number can be set to 3 or a value slightly greater than 3.

[0058] Different surface treatment equipment has different stability and reliability, and the probability of failure to execute instructions is also different. At the same time, different galvanized steel plate surface treatment processes have different requirements for the accuracy and timeliness of equipment execution instructions. For example, for some high-precision galvanizing processes, it is necessary to more strictly control the failure of instruction execution, and the first preset number will be relatively low; while for some relatively simple and high-tolerance processes, the first preset number can be appropriately increased. The first preset number is determined according to the specific characteristics of the equipment and process requirements.

[0059] Generally speaking, the second preset number of times is obtained in a similar manner as the first preset number of times. It needs to be determined based on specific monitoring requirements, different fault types or stages, and comprehensive consideration of historical data, cost efficiency, process characteristics, and other factors. The second preset number of times is a retry threshold set for a specific equipment fault type, a specific processing link, or to meet special quality control requirements.

[0060] Further, as a refinement and extension of the specific implementation of the above embodiment, the device executes the instruction processing method, which also includes the following processing steps: S201. For all the processing procedures of the surface treatment process, the equipment execution instructions in the processing procedures are used as surface treatment steps, and the running surface treatment processes between the equipment execution instructions are used as the process relationship between the surface treatment steps to construct the surface treatment process of the galvanized steel plate.

[0061] For example, in the process of constructing the surface treatment process of galvanized steel sheets, all the processing procedures of conventional surface treatment processes can be determined, the equipment execution instructions in the processing procedures can be used as surface treatment steps, and the running surface treatment processes between the equipment execution instructions can be used as the process relationship between the surface treatment steps to construct the surface treatment process of galvanized steel sheets.

[0062] In some embodiments, for all the processing steps of the surface treatment process, the equipment execution instructions in the processing step are used as the surface treatment steps, and the running surface treatment processes between the equipment execution instructions are used as the process relationship between the surface treatment steps to construct the galvanized steel plate surface treatment process, including: Set the processing parameters and technical parameters of the equipment execution instructions corresponding to each surface treatment step; wherein the processing parameters include at least one of the equipment execution instruction name, execution frequency, number of retries, timeout period and equipment execution instruction processing identifier; the technical parameters include at least one of the database connection information, data call path and equipment execution instruction execution conditions.

[0063] S202. Map each surface treatment step in the surface treatment process of the galvanized steel plate into a surface treatment automation operation program for equipment execution instructions, and generate a process equipment instruction set for calling each surface treatment automation operation program based on the surface treatment automation operation program mapped to each surface treatment step and the process relationship between the surface treatment steps in the surface treatment process of the galvanized steel plate, and construct a surface treatment process route.

[0064] This embodiment constructs a surface treatment automation operation program for executing each device execution instruction, for example, including instructions used by the device execution instruction. Each surface treatment step in the surface treatment process of the galvanized steel plate can be mapped to a surface treatment automation operation program for the device execution instruction, that is, the path of the surface treatment automation operation program that needs to be called when the device execution instruction of each surface treatment step is indicated, so that when the device execution instruction needs to be executed, the corresponding surface treatment automation operation program can be found according to the path. According to the surface treatment automation operation program mapped by the surface treatment step and the process relationship between the surface treatment steps in the surface treatment process of the galvanized steel plate, a process equipment instruction set of the automation operation program is generated, that is, according to the process relationship between each surface treatment step, the surface treatment process between the equipment execution instructions corresponding to the surface treatment step is determined, and then the calling order between the surface treatment automation operation programs corresponding to each equipment execution instruction is determined, and the process equipment instruction set of the automation operation program is generated according to the calling order, so as to call the surface treatment automation operation program with the execution process equipment instruction set, and realize the processing of the equipment execution instruction.

[0065] In some embodiments, each surface treatment step in the surface treatment process of the galvanized steel plate is mapped to a surface treatment automation operation program of the equipment execution instruction, including: determining the surface treatment automation operation program of the equipment execution instruction corresponding to each surface treatment step.

[0066] The calling path of the surface treatment automation running program for calling the corresponding equipment execution instruction when executing each surface treatment step is determined, so as to map each surface treatment step to the surface treatment automation running program for the equipment execution instruction.

[0067] In some embodiments, the equipment execution instruction process relationship is for each sub-equipment execution instruction group in the surface treatment process, determines the running surface treatment process between each sub-equipment execution instruction group, and according to the running surface treatment process between each sub-equipment execution instruction group, adjusts the order of the surface treatment steps corresponding to each sub-equipment execution instruction group in the galvanized steel plate surface treatment process.

[0068] Determine the operating surface treatment process of each equipment execution instruction in the sub-equipment execution instruction group, and adjust the process relationship between each surface treatment step in the surface treatment step corresponding to the sub-equipment execution instruction group in the galvanized steel plate surface treatment process according to the operating surface treatment process of each equipment execution instruction.

[0069] It should be noted that the adjustment process is carried out before surface treatment. The process relationship can be set based on the program set by the system, and the currently required process relationship can be configured into the system. The system will execute the instruction group for each sub-equipment in the surface treatment process according to the preset process relationship, and determine the running surface treatment process between the execution instruction groups of each sub-equipment. According to the running surface treatment process between the execution instruction groups of each sub-equipment, the order of the surface treatment steps corresponding to the execution instruction groups of each sub-equipment in the surface treatment process of the galvanized steel plate is adjusted.

[0070] In this embodiment, the equipment execution instructions in one stage of the surface treatment process can be used as a sub-equipment execution instruction group. For each sub-equipment execution instruction group in the surface treatment process, the running surface treatment processes between each sub-equipment execution instruction group can be determined to ensure the logical correctness of the overall process. The associated surface treatment steps are organized into logical sub-equipment execution instruction groups.

[0071] Each sub-equipment execution instruction group can be based on which sub-equipment execution instruction groups should be executed first and which sub-equipment execution instruction groups can be executed in the order of the surface treatment process. According to the data process logic relationship, the order between the equipment execution instruction groups is adjusted to maximize the execution of the equipment execution instructions in the order of the surface treatment process and the overall efficiency. According to the running surface treatment process between the sub-equipment execution instruction groups, the order between the surface treatment steps corresponding to each sub-equipment execution instruction group in the galvanized steel plate surface treatment process is adjusted. The surface treatment step is obtained by connecting the surface treatment steps corresponding to the sub-equipment execution instruction groups through the process relationship.

[0072] Determine the running surface treatment process of each device execution instruction in the sub-device execution instruction group, confirm the running surface treatment process and process logic relationship of the device execution instruction, and ensure that the device execution instructions in each sub-device execution instruction group are executed in the correct order.

[0073] For each sub-equipment execution instruction group, confirm the running surface treatment process between the execution instructions of each equipment, and ensure that the execution instructions of the subsequent equipment are executed after the surface treatment of the galvanized steel plate is completed in the execution instruction of the front equipment.

[0074] It is necessary to consider the situation where the equipment execution instruction fails and set an appropriate retry strategy or error handling mechanism. According to the running surface treatment process of each equipment execution instruction, the process relationship between the surface treatment steps in the surface treatment step corresponding to the sub-equipment execution instruction group in the galvanized steel plate surface treatment process is adjusted, so as to further verify the process relationship between the surface treatment steps in the galvanized steel plate surface treatment process.

[0075] S203, obtaining the surface treatment process route from the database, parsing the surface treatment process route, and determining the execution instructions of each device and the process equipment instruction set.

[0076] S204, adjusting the equipment execution instructions in the surface treatment process route according to the surface treatment state of the actual surface treatment process, and obtaining equipment execution instructions executed in the order of the surface treatment steps.

[0077] In some embodiments, according to the surface treatment status of the actual surface treatment process, the equipment execution instructions in the surface treatment process route are adjusted to determine the equipment execution instructions executed in the order of the surface treatment steps, which may specifically involve obtaining a custom equipment execution instruction set corresponding to the surface treatment status of the actual surface treatment process.

[0078] For example, in the actual application process, for the surface treatment state of the actual surface treatment process, the custom device execution instruction set corresponding to the surface treatment process under the surface treatment state is obtained, and for each device execution instruction in the custom device execution instruction set, the device execution instruction executed in the order of the surface treatment process and the device execution instruction executed in the order of the surface treatment process are determined, so as to make personalized adjustments to the galvanized steel plate surface treatment process according to the running surface treatment process of the device execution instruction in the surface treatment process under the actual surface treatment state. For each custom device execution instruction set, the custom device execution instruction set executed in the order of the surface treatment process and the custom device execution instruction set executed in the order of the surface treatment process are determined to clarify the running surface treatment process between each device execution instruction group, so as to make personalized adjustments to the galvanized steel plate surface treatment process.

[0079] S205 , executing the device execution instructions according to the sequence of the surface treatment processes, and executing the device execution instructions according to the sequence of the surface treatment processes.

[0080] If all the equipment execution instructions are completed, then check whether the execution instructions of each equipment are completed; if so, return the completion information of the surface treatment of the galvanized steel plate to prompt the user to perform subsequent operations.

[0081] In order to make the surface treatment process of galvanized steel sheets meet actual needs, a process roadmap for surface treatment of galvanized steel sheets is defined. Using the process roadmap for surface treatment of galvanized steel sheets, the processing procedures are represented as surface treatment steps in the process roadmap for surface treatment of galvanized steel sheets, and these surface treatment steps are connected through process logic relationships. The surface treatment step definition method is to use each processing procedure as a surface treatment step in the process roadmap for surface treatment of galvanized steel sheets. The process logic relationship definition is based on defining the process logic relationship between each surface treatment step, that is, some surface treatment steps can only start after other surface treatment steps are completed.

[0082] The equipment execution instruction of this embodiment is defined as a specific equipment execution instruction executed by each surface treatment step. The equipment execution instruction is configured with the parameters required to analyze and verify the galvanized steel plate surface treatment process roadmap.

[0083] This embodiment maps the surface treatment steps and process logic relationships in the galvanized steel plate surface treatment process roadmap to specific device executable instructions and process logic relationships between device execution instructions.

[0084] Specifically, the surface treatment process steps are mapped to equipment execution instructions. Each surface treatment process step in the galvanized steel plate surface treatment process roadmap can be mapped to an actual equipment execution instruction. Determine the completeness of the parameters and configuration data required for each equipment execution instruction. Determine the process logic relationship between equipment execution instructions. Map the process logic relationship in the galvanized steel plate surface treatment process roadmap to the process logic relationship between equipment execution instructions in the scheduling script to ensure that the equipment execution instructions are executed in the correct order.

[0085] Within each equipment execution instruction group, confirm the running surface treatment process and process logic relationship of the equipment execution instruction to ensure that the equipment execution instructions within each equipment execution instruction group are executed in the correct order. For each equipment execution instruction group, confirm the running surface treatment process between each equipment execution instruction to ensure that the subsequent equipment execution instructions are executed after the surface treatment of the galvanized steel plate of the preceding equipment execution instruction is completed.

[0086] Perform surface treatment process route analysis to obtain the surface treatment process route in the database. Perform processing in the order of surface treatment procedures. For the equipment execution instructions that can be processed in the order of surface treatment procedures in the same request group, perform reasonable execution in the order of surface treatment procedures to improve the efficiency and overall performance of equipment execution instructions.

[0087] Finally, after the device executes the instruction, the flag indicating the completion or failure of the surface treatment of the galvanized steel plate is returned according to the execution result of the device execution instruction, so as to facilitate subsequent monitoring and error handling. The execution result of each device execution instruction is monitored and recorded, and the flag indicating the completion or failure of the surface treatment of the galvanized steel plate is recorded. According to the actual situation of the device execution instruction, the device execution instruction status is updated and the flag indicating the completion of the surface treatment of the galvanized steel plate is returned for system monitoring and feedback.

[0088] In this embodiment, the method for parsing and verifying the galvanized steel plate surface treatment process roadmap is to perform grammatical analysis on the text or graphics of the process roadmap to check whether it complies with the specific process roadmap language or symbol specifications. For example, check whether the identification, connection relationship, parameter representation, etc. of each surface treatment step are written correctly, and whether there are grammatical errors or ambiguities.

[0089] Understand the actual meaning and relationship of each component in the process roadmap. Determine the specific operation represented by each surface treatment step, as well as the process logic such as the sequence and parallel relationship between them. For example, it is clear that a certain step is a pickling operation, and its subsequent step is a galvanizing operation, and there is a logical relationship between them in sequence.

[0090] Extract key information from the process roadmap, such as equipment execution instructions, required parameters, etc. Convert information in graphic or text form into a computer-processable data structure for subsequent processing and analysis. For example, extract the execution instructions of the galvanizing equipment and the parameters such as temperature and time required for the instructions from the process roadmap.

[0091] Check whether the process roadmap contains all the necessary steps and information required to complete the surface treatment of galvanized steel sheets. Make sure that no key surface treatment operations or important parameter settings are omitted. For example, check whether all necessary steps such as degreasing, pickling, galvanizing, passivation, etc. are included, and whether the parameters of each step are complete.

[0092] Verify whether the information between the various parts in the process roadmap is consistent. For example, check whether the equipment execution instructions match the configured parameters, and whether the process logic relationship between the steps is reasonable and conflict-free. For example, check whether the parameter settings of the pickling step match the requirements of the subsequent galvanizing step for the surface state of the steel plate.

[0093] Check whether the process roadmap is feasible based on actual production equipment capabilities, process limitations, etc. For example, confirm whether the specified surface treatment equipment can execute the corresponding instructions, whether the performance of the equipment meets the process requirements, and whether the process parameters are within the range of the equipment's operability.

[0094] This application is based on the verification of process logic. Based on the process knowledge and experience of galvanized steel plate surface treatment, a process logic model is established to clarify the logical rules such as the sequence and cause-effect relationship between the various surface treatment steps. For example, degreasing and pickling must be carried out before galvanizing to remove oil and rust on the surface of the steel plate. This is a clear process logic relationship.

[0095] First, compare the generated equipment execution instruction list with the process logic model to check whether the execution order of each instruction conforms to the preset process logic. For example, check whether the execution instructions of the degreasing equipment are arranged first in the instruction list, followed by the instructions of the pickling equipment, and then the instructions of the galvanizing equipment, etc.

[0096] It is important to understand the capabilities, capacities and limitations of each surface treatment equipment. For example, some equipment may require a specific preheating time, or a certain cooling time after processing a batch of steel plates before the next operation.

[0097] This application checks whether there are time conflicts or resource competition issues in the device execution instruction list based on the device's capabilities and limitations. For example, two devices cannot use the same tank liquid at the same time, or a device's execution time is too long, which may cause the subsequent device to wait too long.

[0098] This embodiment can collect and analyze historical data of similar galvanized steel plate surface treatment projects in the past, including the actual process route, equipment execution status, problems encountered, etc. The currently generated equipment execution instruction sequence is compared with historical successful cases to check whether there are obvious differences or unreasonableness.

[0099] Computer simulation software can also be used to simulate the surface treatment process of galvanized steel sheets. Input the equipment execution instructions into the simulation system, simulate the operation of the entire process, and observe whether the execution sequence of each device is reasonable, whether there will be process abnormalities or equipment failures. Analyze the simulation and emulation results to check whether the process parameters meet expectations and whether the surface treatment effect meets the requirements. According to the simulation results, adjust and optimize the equipment execution instruction sequence to ensure the smooth progress of the actual production process.

[0100] In an embodiment of the present invention, in combination with the above-mentioned method, a possible embodiment is given below to illustrate its specific implementation scheme in a non-limiting manner.

[0101] like Figure 2 As shown, the method comprises the following steps: S301. Obtain the surface treatment status and process equipment status of multiple galvanized steel plate surface treatment processes in different time periods.

[0102] S302. Determine the information causing the surface treatment abnormality based on the surface treatment status and process equipment status of multiple galvanized steel plate surface treatment processes.

[0103] S303 , classify the surface treatment abnormality information corresponding to each time period to obtain a key state instruction causing the surface treatment abnormality information.

[0104] In step S301, the surface treatment status and process equipment status of multiple galvanized steel plate surface treatment processes in different time periods are obtained, wherein the multiple galvanized steel plate surface treatment processes may be all galvanized steel plate surface treatment processes running in the surface treatment monitoring terminal or may be part of the galvanized steel plate surface treatment processes.

[0105] In step S302, the correlation between different surface treatment processes of galvanized steel plates is analyzed based on the surface treatment status and process equipment status of multiple surface treatment processes of galvanized steel plates, and the surface treatment processes of galvanized steel plates that may affect each other are determined, such as abnormal amount of degreaser in the degreasing tank, uneven spraying of the degreaser on the surface of the steel plate by the spray device, and the heating system controlling the temperature of the degreaser exceeding the threshold value, which affects the degreasing speed.

[0106] The acid flow rate in the acid circulation system is abnormal, the ventilation device is not turned on, or the appropriate exhaust volume cannot be matched to discharge the acid mist generated during the pickling process, affecting the safety of the working environment. The water volume in the washing tank used to soak and clean the steel plate is low, and the clean water spray equipment is not aimed at the steel plate. The stirring device does not reach the stirring time, causing uneven composition of the plating solution.

[0107] The molten zinc liquid in the galvanizing pot is not maintained within the zinc liquid temperature threshold range, the rectifier output current of the electroplating tank exceeds the threshold or is unstable, and the anode is not replenished with enough zinc ions during the electroplating process.

[0108] The heat dissipation of the air cooling equipment is insufficient; the circulating water flow of the water cooling equipment is lower than the threshold, or the water temperature is higher than the threshold, so that the steel plate cannot be cooled quickly. The amount of passivation liquid in the passivation tank is low, and the wastewater treatment system does not meet the standards for treating passivation wastewater containing heavy metal ions.

[0109] In some embodiments, after determining the surface treatment abnormality information caused by each time period, the surface treatment status and process equipment status of multiple galvanized steel plate surface treatment processes in the corresponding time period can be marked based on the surface treatment abnormality information caused by each time period.

[0110] In step S303, the surface treatment abnormality information corresponding to each time period is classified and processed to obtain the key state instructions causing the surface treatment abnormality information, wherein the device can classify the surface treatment abnormality information corresponding to each time period through a hierarchical classification method to obtain the key state instructions causing the surface treatment abnormality information. After determining the surface treatment abnormality information corresponding to each time period, the surface treatment abnormality information corresponding to each time period is classified and processed to obtain the key state instructions causing the surface treatment abnormality information, wherein the key state instructions may be the largest number of reasons after classification processing.

[0111] In some embodiments, after determining the key status instructions, the key status instructions and the surface treatment status and process equipment status of multiple galvanized steel plate surface treatment processes in each time period can be displayed to the surface treatment personnel, so that the surface treatment personnel can determine the key galvanized steel plate surface treatment process and the surface treatment status and process equipment status of the key galvanized steel plate surface treatment process based on the key status instructions.

[0112] In some embodiments, after determining the critical state instructions, the target surface processing state and process equipment state associated with the critical state instructions are determined based on the critical state instructions, and the critical state instructions and the target surface processing state and process equipment state are displayed, so that the surface processing personnel can perform processing based on the critical state instructions and the target surface processing state and process equipment state.

[0113] In some embodiments, when the preset target galvanized steel plate surface treatment process is multiple time periods, for each time period, the status of each preset target galvanized steel plate surface treatment process can be determined simultaneously, and it can be determined whether the operating status of each preset target galvanized steel plate surface treatment process is the preset status; the priority of the preset target galvanized steel plate surface treatment process can also be set in advance, and the operating status of each preset target galvanized steel plate surface treatment process can be determined step by step according to the priority of multiple preset target galvanized steel plate surface treatment processes, and whether the status of each preset target galvanized steel plate surface treatment process is the preset status.

[0114] In response to the running state of the preset target galvanized steel sheet surface treatment process being the preset state and the galvanized steel sheet surface treatment process causing surface treatment abnormality information being the preset target galvanized steel sheet surface treatment process, based on the surface treatment state and process equipment state of the associated galvanized steel sheet surface treatment process of the associated preset target galvanized steel sheet surface treatment process in multiple galvanized steel sheet surface treatment processes, it is determined that the preset target galvanized steel sheet surface treatment process causes the surface treatment abnormality information.

[0115] In some embodiments, based on the preset target galvanized steel sheet surface treatment process, the galvanized steel sheet surface treatment process that causes surface treatment abnormality information is the preset target galvanized steel sheet surface treatment process, and based on the surface treatment status and process equipment status of the associated galvanized steel sheet surface treatment process associated with the preset target galvanized steel sheet surface treatment process among multiple galvanized steel sheet surface treatment processes, it is determined that the preset target galvanized steel sheet surface treatment process causes surface treatment abnormality information. Among them, the associated galvanized steel sheet surface treatment process associated with the preset target galvanized steel sheet surface treatment process can be a galvanized steel sheet surface treatment process created by the preset target galvanized steel sheet surface treatment process, or a galvanized steel sheet surface treatment process that interacts with the preset target galvanized steel sheet surface treatment process, or a galvanized steel sheet surface treatment process that provides services for the preset target galvanized steel sheet surface treatment process.

[0116] In some embodiments, based on each associated galvanized steel sheet surface treatment process, combined with the surface treatment state and process equipment state of the associated galvanized steel sheet surface treatment process, it is determined whether the operation state of the associated galvanized steel sheet surface treatment process is a preset state. The associated galvanized steel sheet surface treatment process and the preset target galvanized steel sheet surface treatment process are galvanized steel sheet surface treatment processes that have mutual influence and resource competition, and the operation state of the associated galvanized steel sheet surface treatment process is determined based on the surface treatment state and process equipment state of the associated galvanized steel sheet surface treatment process.

[0117] In some embodiments, the surface treatment status and process equipment status of each associated galvanized steel plate surface treatment process may directly include the operating status of the associated galvanized steel plate surface treatment process, and the operating status of the associated galvanized steel plate surface treatment process may be directly determined based on the surface treatment status and process equipment status of the associated galvanized steel plate surface treatment process.

[0118] In some embodiments, there is an associated galvanized steel sheet surface treatment process whose operating state is a preset state, and based on the associated galvanized steel sheet surface treatment process which is the preset state, sub-associated galvanized steel sheet surface treatment processes whose operating states are not the preset states are determined, and based on the surface treatment state and process equipment state of the sub-associated galvanized steel sheet surface treatment processes, the preset target galvanized steel sheet surface treatment process causes surface treatment abnormality information.

[0119] Among them, the sub-associated galvanized steel plate surface treatment process is a galvanized steel plate surface treatment process among multiple galvanized steel plate surface treatment processes, the sub-associated galvanized steel plate surface treatment process can be one or more, the sub-associated galvanized steel plate surface treatment process is directly or indirectly associated with the associated galvanized steel plate surface treatment process in a preset state, such as the sub-associated galvanized steel plate surface treatment process can be a galvanized steel plate surface treatment process that has a resource competition relationship with the associated galvanized steel plate surface treatment process, the sub-associated galvanized steel plate surface treatment process can also be an associated galvanized steel plate surface treatment process of a galvanized steel plate surface treatment process that has a resource competition relationship with the associated galvanized steel plate surface treatment process, and the galvanized steel plate surface treatment process directly associated with the sub-associated galvanized steel plate surface treatment process is in a preset state.

[0120] In some embodiments, the target surface treatment state and process equipment state associated with the key state instruction are determined among the surface treatment states and process equipment states of multiple galvanized steel plate surface treatment processes in different time periods. In some embodiments, after the equipment determines the key state instruction, the target surface treatment state and process equipment state can be determined based on the surface treatment abnormality information corresponding to the key state instruction and the surface treatment states and process equipment states of multiple galvanized steel plate surface treatment processes in each time period. For example, the surface treatment abnormality information corresponding to the surface treatment states and process equipment states of multiple galvanized steel plate surface treatment processes in each time period is the surface treatment state and process equipment state of the key state instruction, which is determined as the target surface treatment state and process equipment state; if the key state instruction includes multiple, the surface treatment abnormality information corresponding to the surface treatment states and process equipment states of multiple galvanized steel plate surface treatment processes in each time period can be determined as the target surface treatment state and process equipment state including the surface treatment abnormality information caused by any reason in the key state instruction.

[0121] In some embodiments, based on the abnormal information causing the surface treatment, the surface treatment status and process equipment status of multiple galvanized steel plate surface treatment processes are marked; the surface treatment status and process equipment status of multiple galvanized steel plate surface treatment processes in different time periods, the target surface treatment status and process equipment status associated with the key status instruction are determined, including: based on the marking of the surface treatment status and process equipment status of multiple galvanized steel plate surface treatment processes in each time period, the target surface treatment status and process equipment status associated with the key status instruction are determined in the surface treatment status and process equipment status of multiple galvanized steel plate surface treatment processes in different time periods.

[0122] This embodiment can accurately associate the target surface treatment state and process equipment state through the key state instruction, especially determine the target state based on the information causing the surface treatment abnormality, and locate the specific link and corresponding equipment state where the abnormality occurs in the surface treatment process of the galvanized steel plate. When there are multiple key state instructions, the surface treatment state and process equipment state related to the cause of any key state instruction can be determined as the target state.

[0123] Based on the abnormal information causing the surface treatment, the status of multiple galvanized steel plate surface treatment processes is marked, and then the target state associated with the key status instructions is determined by marking, so that the status management of the entire surface treatment process is orderly, which facilitates the traceability and analysis of the process status in different time periods, and continuously optimizes the surface treatment process and equipment operation status.

[0124] In combination with the above method, this embodiment also provides a galvanized steel plate surface treatment process monitoring system, the system includes: a database, a surface treatment monitoring terminal and a galvanized steel plate production monitoring server.

[0125] The surface treatment monitoring terminal obtains the surface treatment process route from the database, analyzes the surface treatment process route, and determines the execution instructions of each device and the process equipment instruction set.

[0126] The surface treatment monitoring terminal adjusts the equipment execution instructions in the surface treatment process route according to the surface treatment status of the actual surface treatment process, and obtains the equipment execution instructions executed in the sequence of the surface treatment process of the galvanized steel plate; the equipment execution instructions are executed in the sequence of the surface treatment process to control the operation of the processing equipment.

[0127] During the execution process, if the device execution instruction fails to execute, the device execution instruction is executed repeatedly; if the number of times the device execution instruction is repeated reaches a first preset number, the name of the device execution instruction that failed to execute and the processing device corresponding to the instruction are recorded.

[0128] The surface treatment monitoring terminal sends the surface treatment status and process equipment status to the galvanized steel plate production monitoring server; the galvanized steel plate production monitoring server displays the surface treatment status and process equipment status information in real time.

[0129] The surface treatment monitoring terminal can pre-set the time interval for collecting the surface treatment status and process equipment status of the surface treatment process of the galvanized steel plate. The surface treatment monitoring terminal includes a storage device. After collecting the surface treatment status and process equipment status of the surface treatment process of the galvanized steel plate, the surface treatment monitoring terminal can store the surface treatment status and process equipment status of the surface treatment process of the galvanized steel plate in the storage device. The surface treatment monitoring terminal can store the surface treatment status and process equipment status of the surface treatment process of the galvanized steel plate according to the time interval for collecting the surface treatment status and process equipment status of the surface treatment process of the galvanized steel plate.

[0130] In this embodiment, the galvanized steel plate production monitoring server detects surface treatment abnormality information in response to the surface treatment monitoring terminal running multiple galvanized steel plate surface treatment processes, and receives the surface treatment status and process equipment status of multiple galvanized steel plate surface treatment processes in different time periods sent by the surface treatment monitoring terminal. After responding to the surface treatment monitoring terminal detecting the surface treatment abnormality information, the server receives and displays the surface treatment status and process equipment status of multiple galvanized steel plate surface treatment processes in different time periods.
