Description

TECHNICAL FIELD

[0001] The present application relates to the field of heat treatment production line steel plate detection, in particular to a heat treatment production line steel plate information tracking and intelligent management and control method and system. BACKGROUND

[0002] The heat treatment production process of the steel industry includes normalizing, normalizing, tempering, quenching, etc. The steel plate that needs to be heat treated is first cleaned by a shot blasting machine and then conveyed to the pre-oven area by a roller. According to the production process plan, it is placed in the designated stack position of the oven area by the electromagnetic crane. The steel plate that needs to be put into the furnace is lifted by the electromagnetic crane and put into the furnace roller. After surface inspection and treatment, the steel plate is heated in the heat treatment furnace. The heat treatment furnace controls the temperature of each section in the length direction according to the process requirements, so that the steel plate completes the heat treatment process in the appropriate temperature field. After being discharged from the furnace, the steel plate that needs to be quenched is treated by the quenching process. After the above processes are completed, the steel plate is conveyed to the straightening machine by the roller and the transverse moving device for straightening or directly sent to the cooling bed. The steel plate that needs to be sampled is cut into a sample by a sampling shear. Finally, the steel plate is sprayed to become a finished plate, completing the heat treatment production process. The finished plate is sent to the finished plate warehouse.

[0003] At present, the heat treatment furnace and quenching machine of the heat treatment process generally have a relatively perfect first and second level system, but the equipment level of the area outside the heat treatment furnace is poor. The key equipment information in the area is in an island and fragmented state. The steel plate information transmission in the process is blocked. The material cannot be tracked in real time. The material information verification and input generally need manual operation, which leads to the problem that the production rhythm cannot be improved and some information errors are easily generated.

[0004] With the development of new technologies such as artificial intelligence and computers, the material information matching technology based on machine vision is developed to automatically identify and spray the steel number. New intelligent detection equipment is added to build a full-process intelligent management and control platform covering regional accurate tracking, production scheduling, length verification, defect detection and intelligent unmanned spraying, which is of great significance to the improvement of the production efficiency of the heat treatment process.

[0051] Example implementations will now be described more fully with reference to the accompanying drawings. Example implementations may, however, be implemented in many different forms and should not be construed as limited to the examples set forth herein; rather, these implementations are provided so that this disclosure will be thorough and complete, and will fully convey the scope of example implementations to those skilled in the art. The features, structures, or characteristics described in connection with the examples can be combined in any suitable manner in one or more implementations. In the description below, numerous specific details are provided, such as examples of components, to provide a thorough understanding of example implementations.

[0052] To solve the problem of blocked information transmission within the process, real-time tracking of materials, manual operation of material information verification and entry, etc., which leads to the problem of inability to improve production rhythm and prone to information errors. Referring to Figure 1 The present application provides a heat treatment production line steel plate information tracking and intelligent management and control method, which comprises the following steps:

[0053] S100: receiving a heat treatment job plan PDI from a manufacturing execution system.

[0054] Specifically, at the starting end of the heat treatment production line, the heat treatment job plan PDI issued by the manufacturing execution system (MES) is received through the industrial Ethernet, the PDI contains the basic information of the steel plate, such as the steel plate number, steel type, specification, etc., and the process requirements, such as the treatment mode, target temperature, etc., and the PDI received in this step provides basic data support for the whole process.

[0055] S200: When the steel plate is conveyed to the front area of the shot blasting machine, the steel plate surface mark is automatically identified by the shot blasting machine front plate number recognition device, and the identification result is sent.

[0056] When the steel plate is conveyed to the front area of the shot blasting machine by the roller, the shot blasting machine front plate number recognition device arranged on the side of the roller automatically takes a picture of the steel plate surface mark, extracts the plate number information by image processing algorithm and sends it to the control system. The front recognition and number spraying of the shot blasting machine ensure the uniqueness and traceability of the steel plate identity.

[0057] S300: According to the identification result, the corresponding heat treatment operation plan is matched, the shot blasting rear number spraying machine sprays the heat treatment number on the surface of the steel plate, and the steel plate on-line operation is completed.

[0058] The system matches the identification result with the received PDI, confirms the steel plate identity, triggers the number spraying machine behind the shot blasting machine to spray the heat treatment number generated by the system on the surface of the steel plate, and completes the steel plate on-line operation.

[0059] S400: The heat treatment furnace front recognition device identifies the steel plate in the furnace loading area and obtains the steel plate identification result in the furnace loading area. According to the steel plate identification result in the furnace loading area, the process heating parameters of the steel plate are transmitted to the heat treatment furnace control system.

[0060] S500: After the steel plate completes the heating treatment in the heat treatment furnace, the heat treatment furnace generates and sends the discharge information containing the steel plate heat treatment number.

[0061] The steel plate continues to be conveyed to the front area of the heat treatment furnace, and the heat treatment furnace front recognition device identifies the steel plate again. After confirming the heat treatment number, the system extracts the corresponding process heating parameters from the PDI and transmits them to the heat treatment furnace control system to guide the heating process in the furnace. The heat treatment furnace front recognition and parameter transmission realize the precise control of the process.

[0062] S600: Match the discharge information with the steel plate information on the line, and update the steel plate information state to the post-furnace area state.

[0063] After heating is completed, the heat treatment furnace sends the discharge information through PLC, and the system matches the discharge information with the steel plate information tracked on the line, updates the state of the steel plate to "post-furnace area", and matches the discharge information to ensure the continuity of the production process.

[0064] S700: The sampling shear area entrance recognition device identifies the steel plate in the cooling bed area and obtains the steel plate identification result in the sampling shear area.

[0065] After the steel plate is cooled by the cooling bed, it is conveyed to the sampling shear area, and the sampling shear entrance recognition device identifies the steel plate heat treatment number.

[0066] S800: Based on the identification result, the length measurement data is automatically obtained, the length is checked, and the steel plate information is transmitted for steel plate surface inspection.

[0067] The system automatically calls the length gauge to obtain the actual length of the steel plate, and verifies it with the planned length in the PDI. In combination with the sampling shear identification in step S700 and the length verification in this step, the product quality is further ensured.

[0068] S900: When the steel plate is conveyed to the front area of the marking machine, the steel plate heat treatment number is identified by the marking machine entrance identification device, the steel plate identification result of the marking machine is obtained, and the steel plate identification result of the marking machine is sent.

[0069] S1000: Generate the marking MD data according to the steel plate information, the marking and the default parameters, respond to the marking request of the marking machine and return the marking MD data.

[0070] S1100: Receive the marking performance MF fed back by the marking machine, and update the steel plate information state to the warehouse state.

[0071] Finally, the steel plate is conveyed to the front area of the marking machine, the marking machine entrance identification device identifies the heat treatment number again, the system generates the marking MD data according to the current steel plate information and the preset marking parameters, responds to the marking request of the marking machine, controls the marking machine to perform marking, receives the marking performance MF after completion and updates the state to "warehouse".

[0072] Through the marking machine identification and marking control, the finished product identification automation is realized, and the final state update forms a complete production closed loop.

[0073] The embodiment solves the problems of easy error in manual recording of steel plate information and low production efficiency caused by process breakpoints in the traditional heat treatment production line through the linkage of the full-process identification device and the system, realizes the automatic tracking and management of the full-process information of the steel plate from the online to the warehouse, reduces human errors through automatic identification, improves the accuracy of information, improves the production efficiency due to seamless connection of the process, guarantees the product quality, and realizes real-time check of production data.

[0074] In some embodiments of the present application, continuing to refer to Figure 1 , further comprising the step of:

[0075] S210: When the plate number identification device in front of the shot blasting machine cannot automatically identify the surface marking of the steel plate, a manual identification operation or manual confirmation of the steel plate information is triggered to complete the steel plate online operation;

[0076] S410: When the identification device in front of the heat treatment furnace cannot identify the steel plate, a manual identification operation or manual selection of the steel plate information is triggered to complete the furnace loading information transmission operation;

[0077] S710: When the sampling shear entrance identification device or the marking machine entrance identification device identifies abnormally, a manual identification operation or manual selection of the steel plate information is triggered to complete the information transmission operation.

[0078] It can be understood that in the front area of the shot blasting machine, if the OCR recognition system cannot extract the steel plate number due to surface stains, blurred marks, etc., the system automatically pops up a manual recognition interface, and the operator can complete information confirmation by inputting the plate number, and after confirmation, triggers the marking machine to print the heat treatment number. Further, in the front area of the heat treatment furnace, if the recognition system cannot recognize the heat treatment number, the system provides a manual selection function, and the operator selects the corresponding steel plate from the current online steel plate list, and the system extracts its process parameters and transmits them to the furnace control system. Similarly, in the sampling shear or marking machine inlet area, if the recognition device fails, the operator can manually input the heat treatment number through the industrial computer interface, and the system completes the length data acquisition or printing data generation according to the input information.

[0079] The steps of the embodiment serve as a supplementary mechanism for automatic identification, ensuring that the production process can continue when the equipment is abnormal, and avoiding the shutdown of the entire line due to local faults. The production interruption problem caused by the insufficient reliability of the automatic identification device is solved, the fault tolerance of the system is improved, the production continuity is effectively guaranteed, the loss caused by shutdown is reduced, and the availability of the system is improved.

[0080] In some embodiments of the present application, in step S800, the step further includes:

[0081] S810: In the sampling shear area, according to the steel plate identification result of the sampling shear area, the length measurement result is automatically obtained and the length verification operation is completed;

[0082] S820: and when the length verification result does not match the operation plan, triggering an alarm operation and accepting manual intervention.

[0083] Specifically, after the sampling shear inlet recognition device identifies the heat treatment number of the steel plate, the system calls the laser length measuring instrument deployed beside the roller, calculates the actual length of the steel plate by emitting a laser beam and receiving a reflected signal. The system compares the actual length with the planned length in the PDI, and if the deviation exceeds the preset threshold, an alarm prompt is popped up through the industrial computer interface. After the operator arrives on site, he or she can check the detailed data through the system interface to confirm whether it is a measurement error or an abnormal steel plate cutting, and adjust the subsequent processing flow according to the actual situation.

[0084] The traditional manual length measurement has the problems of low efficiency, large error, and inability to handle abnormal situations in time. The embodiment ensures that the length of the steel plate meets the process requirements through automatic length measurement and verification, and the alarm and manual intervention mechanism prevents unqualified products from flowing into the next process, improves the quality control level, and can quickly respond to abnormalities and ensure product qualification rate.

[0085] In some embodiments of the present application, the step of generating printing data based on the default parameters S1000 further includes:

[0086] S1010: Automatically generate the printing MD data containing all setting values by combining the printing PDI data from the manufacturing execution system, the steel plate information and the default printing parameters;

[0087] S1020: The printing MD data is used to respond to the printing request of the marking machine and control the printing execution.

[0088] It can be understood that the finished product printing control unit platform receives the printing PDI data such as customer identification, production batch from the MES, combines the current steel plate information and the preset default printing parameters such as font height 50mm, horizontal position distance from edge 200mm, and vertical position distance from edge 150mm, and generates the printing MD data through a data integration algorithm.

[0089] The printing MD data contains all setting values such as specific printing content, printing position coordinates, font attributes, etc. When the marking machine sends a printing request RD, the system matches the corresponding printing MD data according to the heat treatment number in the RD, and sends the printing MD data to the marking machine controller through the industrial Ethernet to guide the printing head to execute the printing action.

[0090] The embodiment uniformly manages the printing parameters, ensures the consistency of the printing content, automatically generates the data to reduce the manual configuration errors, realizes the standardization of the printing data, can guarantee the printing quality, and reduces the manual intervention.

[0091] In some embodiments of the present application, the step of S100 of receiving the heat treatment job plan PDI from the manufacturing execution system further comprises:

[0092] S110: Generate a heat treatment process job plan by combining the preset process parameters; the job plan contains the serial number of the steel plate, the heat treatment number, the steel plate number, the steel grade, the treatment mode and the heating target temperature.

[0093] Specifically, after the system receives the PDI issued by the MES, the preset process parameters corresponding to the steel grade and the treatment mode are extracted from the process parameter library, and the heat treatment process job plan is generated by combining the steel plate basic information in the PDI.

[0094] S120: The generated job plan is manually adjusted from the initial state to the to-be-executed state, and then to the executed state after the steel plate is online.

[0095] The initial state of the job plan is "to be executed", and it is adjusted to "to be executed" after the planner confirms that the parameters are correct through the system interface. When the steel plate is recognized by the shot blasting machine and is online after printing the heat treatment number, the system automatically updates the job plan state of the steel plate to "executing", and displays the current process of the steel plate on the production board in real time.

[0096] The embodiment combines PDI with process parameters to form an executable production plan, and realizes state management to visualize production progress. Plan efficiency is improved, process control is enhanced, and production scheduling is facilitated.

[0097] Another aspect of the embodiment of the present application provides a heat treatment production line steel plate information tracking and intelligent management and control system, as shown in Figure 2 The system comprises an identification interaction unit platform and a control layer interaction unit platform.

[0098] The identification interaction unit platform is configured to automatically receive identification trigger signals from a shot blasting machine front plate number identification device, a heat treatment furnace front identification device, a sampling shear inlet identification device, and a number spraying machine inlet identification device, and send identification result feedback. The control layer interaction unit platform is configured to obtain the identification trigger signals, send heat treatment furnace entry information, and receive exit information.

[0099] Specifically, the identification interaction unit platform is deployed at key process points of the production line, such as the front of the shot blasting machine area, the front of the heat treatment furnace area, the sampling shear inlet area, and the number spraying machine inlet area. The identification interaction unit platform is connected with the field identification devices through industrial Ethernet. When the steel plate reaches the identification area, the identification device triggers a signal, the identification interaction unit platform automatically receives and processes the image or scan data, extracts the plate number or heat treatment number, and then sends it to the system core. The control layer interaction unit platform is connected with devices such as heat treatment furnace PLC and number spraying machine controller, obtains the furnace state, sends the entry instruction, and receives the exit information to update the steel plate state.

[0100] The embodiment realizes data interaction between field devices and the system through the identification interaction unit, and completes the transmission of device control instructions and state feedback through the control layer interaction unit, thereby improving the efficiency of device linkage and enhancing the collaboration of devices.

[0101] In some embodiments of the present application, the system further comprises a Mes data interaction unit platform and a finished product spraying control unit platform. The Mes data interaction unit platform is configured to receive job plans and process parameters, transmit spraying data and process job feedback. The finished product spraying control unit platform is configured to match spraying MD data based on identification results and spraying PDI data, receive spraying request RD, send spraying MD data, and receive spraying state and spraying performance MF.

[0102] Specifically, the Mes data interaction unit platform communicates with the MES system, receives heat treatment job plans PDI and process parameters, and simultaneously feeds back production performance to the MES system. The finished product spraying control unit platform is connected with the identification interaction unit platform and the number spraying machine. When the number spraying machine inlet identification device sends the heat treatment number, the platform obtains corresponding spraying PDI data from the Mes data interaction unit, generates MD data by combining default parameters, responds to the RD request of the number spraying machine to send MD data, and receives the MF performance after spraying to update the steel plate state.

[0103] The embodiment realizes information synchronization of the system and the upper MES through the Mes data interaction unit, and the finished product spray printing control unit completes generation and execution control of spray printing data, thereby improving data consistency and guaranteeing spray printing accuracy.

[0104] In some embodiments of the present application, continuing to refer to Figure 2 As shown in the figure, the system further includes a message distribution unit platform and a platform core unit platform; wherein the message distribution unit platform is configured to distribute messages of each unit; and the platform core unit platform is configured to store data, control core business and display a front-end interface in combination with the platform and the platform front end.

[0105] Specifically, the message distribution unit platform adopts a message queue middleware, receives messages from the identification interaction unit, the control layer interaction unit and the Mes data interaction unit, and distributes the messages to corresponding processing modules according to message types. The platform core unit platform is deployed on a server side, integrates a database and business logic, and a front end displays a real-time position and state of a steel plate through a Web interface and provides a manual intervention entry.

[0106] In some embodiments of the present application, continuing to refer to Figure 2 As shown in the figure, the finished product spray printing control unit platform is further configured to: generate spray printing MD data according to an entry recognition result of the marking machine; return the spray printing MD data according to a spray printing request RD; and receive spray printing performance MF and update a state of the steel plate.

[0107] After receiving the heat treatment number sent by the marking machine entry recognition device, the finished product spray printing control unit platform queries spray printing PDI data and default spray printing parameters of the corresponding steel plate from a database of the platform core unit, generates MD data containing spray printing content, position and font attributes through data splicing. When the marking machine sends an RD request, the platform matches the MD data according to the heat treatment number and returns. After the spray printing is completed, the marking machine sends MF performance, and the platform associates the MF performance with the steel plate information and updates the state of the steel plate to “in storage”.

[0108] The embodiment realizes accurate generation and execution feedback of spray printing data, forms closed-loop management of the spray printing process, improves the level of spray printing automation, and guarantees the quality of spray printing.

[0109] In some embodiments of the present application, the identification interaction unit platform is further configured to: when automatic reception of an identification trigger signal fails, trigger manual identification or manual confirmation of the steel plate information, and complete an on-line operation or information transmission operation of the steel plate.

[0110] Understandably, if the identification interaction unit platform does not receive a trigger signal from the on-site identification device within the specified time, the system automatically determines that the identification has failed and displays a manual identification interface. Operators can enter the steel plate heat treatment number or scan a QR code through the interface, confirm the information, and trigger subsequent marking or furnace loading operations.

[0111] This embodiment serves as a backup solution for automatic identification, ensuring that the production process is not interrupted when identification fails, improving system fault tolerance, and guaranteeing production continuity.

[0112] As can be seen from the above embodiments, this application provides a method and system for tracking and intelligently managing steel plate information in a heat treatment production line, referring to... Figure 3 As shown, the specific process is as follows: After the MES (Manufacturing Execution System) issues the heat treatment work plan (PDI), the system generates a work plan and waits for the steel plate to be online. When the steel plate is transported to the area in front of the shot blasting machine, the plate number is automatically identified and the heat treatment number is printed to complete the online process. After online, the steel plate information first enters the shot blasting machine area, which contains the steel plate information from the time it is online in the shot blasting machine until it is identified in the heat treatment furnace. After the steel plate is online in front of the shot blasting machine, the destination of the steel plate in the work information determines the heat treatment furnace it enters. When the steel plate enters the furnace loading area in front of the heat treatment furnace, the furnace front identification automatically identifies the heat treatment number of the steel plate. The platform obtains detailed information about the steel plate and process heating parameters based on the feedback heat treatment number. This information is automatically transmitted to the corresponding heat treatment furnace, realizing the automatic transmission of furnace loading information.

[0113] When an anomaly is detected, the detection can be triggered manually, or the corresponding steel plate information can be manually selected on the platform to complete the furnace loading information transmission operation.

[0114] Each heat treatment furnace has a different function. When the steel plate information is transmitted to the corresponding heat treatment furnace, the heat treatment furnace completes the information tracking inside the furnace. When the steel plate completes the heating process and exits the furnace, the heat treatment furnace automatically sends the exit information to the platform. The platform matches the corresponding steel plate information according to the received exit information and transmits the steel plate processing status to the area behind the furnace.

[0115] The area behind the furnace includes the entire region from the point where the steel plate exits the heat treatment furnace until it is identified by the sampling shear. After the steel plate processing status is transmitted to the area behind the furnace, the area behind the furnace determines whether the steel plate information has been transmitted to the sampling shear area based on the identification result of the sampling shear. When an identification anomaly occurs, the corresponding steel plate information can also be selected to manually complete the information transmission.

[0116] After the sampling shear inlet identification device identifies the steel plate, the steel plate processing status is transmitted to the sampling shear area. Within the sampling shear area, the system automatically acquires the length measurement results and completes the length verification. When the length does not match, an alarm is triggered accordingly to ensure accurate sampling of the sampling plate.

[0117] The sampling and shearing area automatically matches the steel plate information and transmits it to the table inspection device, and collects the table inspection performance. When the plate inlet recognition device of the marking machine recognizes the steel plate, the steel plate processing state is transmitted to the marking area. When the marking recognition device is abnormal, the corresponding steel plate information can also be selected to manually complete the transmission of information.

[0118] When the plate inlet recognition device of the marking machine recognizes the steel plate, the steel plate processing state is transmitted to the marking area, and the automatic marking control and other operations of the steel plate are completed in the marking area. The process-related parameters of the steel plate are collected and saved or reported. After the steel plate enters the marking area, the platform automatically generates marking MD data according to the current entering steel plate information, marking PDI of the Mes, and some default parameter settings of marking. The marking MD data contains all the setting values required for marking execution. When the steel plate reaches the marking and is positioned, the marking machine automatically sends an RD request to the platform, and the platform returns the generated marking MD data. After the marking is completed, the marking machine automatically feeds back the MF marking result performance, and the platform adjusts the steel plate information state to the warehouse state after receiving the marking performance.
