[0030] The embodiment of the present invention provides an integrated dynamic scheduling system for iron and steel rolling production, such as Figure 1 As shown, it includes: a data acquisition and transmission module, a process rule library and a dynamic scheduling module. Among them, the data acquisition and transmission module and the dynamic scheduling module can exchange information. The data acquisition and transmission module is used to receive the external production plan in real time and forward the production plan to the dynamic scheduling module, so that the dynamic scheduling module can schedule the production process of iron and steel rolling according to the production plan; the process rule library is used to store the process rule requirements in the iron and steel rolling production process, and the dynamic scheduling module can retrieve the process rule requirements stored in the process rule library. The dynamic scheduling module is used to coordinate the production process of the iron area, steel area and casting and rolling section according to the production plan and process rule requirements, and compile the operation plan of the iron area, steel area and casting and rolling section; the data acquisition and transmission module is also used to collect the production performance and logistics performance in the production process in real time and forward it to the dynamic scheduling module. The dynamic scheduling module is used to dynamically adjust the operation plan in real time according to the production performance and logistics performance.

[0031] The integrated dynamic scheduling system of the present invention receives the production plan of the MES planning system in real time through the data acquisition and transmission module, automatically compiles the planned operations according to the production plan and process rules, coordinates the planned operations of each section in the iron and steel rolling production process, opens up the overall production process, and is highly integrated with the planning system. At the same time, the data acquisition and transmission module collects information such as production performance and logistics performance at the production site, realizes intelligent monitoring of the production process, grasps material flow information, tracks and manages materials in all directions, realizes the integration and sharing of data in each link of the production process, and establishes a comprehensive production data platform. In addition, the dynamic scheduling module also dynamically adjusts the production operations according to the production performance and logistics performance, optimizes the production rhythm, overcomes the disturbance factors in the production process, and realizes the intelligence and automation of production scheduling.

[0032] In some embodiments, the process rule library is used to store all constraints in the production process, that is, process rule requirements. Specifically, the process rule library is a rule feature or attribute set in advance based on general industry standards and special production requirements of the production plant, and the operator can maintain the process rule library according to the special production requirements of the plant.

[0033] like Figure 2 As shown in the figure, the process rule requirements include the process paths, production steps, operation time requirements, temperature requirements, composition requirements, transportation time requirements, equipment requirements and production event requirements corresponding to different steel grades. Among them, the production event requirements include stirring, vacuuming and other events required in the production process.

[0034] In this embodiment, for each steel grade, corresponding process rule requirements are stored in the process rule library, so as to define all parameters in the process production process and provide basic data support for planning simulation models, production planning and scheduling, dynamic optimization and adjustment of operation plans, and lean evaluation and analysis.

[0035] The embodiment of the present invention provides rule requirements for the production process by establishing a refined process rule library, thereby improving the reliability of the production scheduling plan.

[0036] In some embodiments, the dynamic scheduling module can determine the process path based on the type of steel to be produced and determine the main process flow of the production process. Specifically, in the production process, it is necessary to consider the production combination strategy of each process formed by equipment turnover time, equipment capacity, process and quality requirements, and tooling equipment replacement frequency. The dynamic scheduling module uses the production combination strategy as a constraint and gives the combination of production tasks and production sequence as the initial value of the job plan; when optimizing the scheduling plan, the optimization strategy includes: optimizing and iterating with the goal of meeting delivery dates, reducing the generation of waste materials, reducing inventory, reducing the number of equipment changes, reducing the idle time of bottleneck equipment, and reducing energy consumption.

[0037] Specifically, the dynamic scheduling module combines the actual production situation at the production site, establishes a task allocation mechanism for equipment in each process and a task coordination mechanism between upstream and downstream processes based on the process rules and optimization strategies of each process, automatically compiles the work plan for each workstation, and performs a full-process simulation of the entire production process to optimize the scheduling plan, refine the operation time of each workstation, reduce waiting time, improve production efficiency, and ensure refined production, completion of production tasks, and smooth logistics.

[0038] Exemplarily, the dynamic scheduling module parses the furnace operation according to the furnace plan of the production plan, and automatically selects the specific equipment to execute the production plan in combination with the process path specified by the process rules of the steel type being produced and the operating conditions of multiple similar equipment in the production system, such as the converter, refining furnace, continuous casting machine, etc., and automatically compiles the furnace operation production path. It simulates and calculates the production start time, production equipment, production end time, transportation time, etc. of each process in the production process to determine the optimal production path combination; it also generates a turnover scheduling plan for logistics.

[0039] In some embodiments, Figure 1 As shown, the dynamic scheduling module includes: an iron and steel dynamic scheduling module, a steel casting dynamic scheduling module, and a casting and rolling dynamic scheduling module that are coordinated with each other. Among them, the iron and steel dynamic scheduling module, the steel casting dynamic scheduling module, and the casting and rolling dynamic scheduling module can exchange the operation plans of each section, so that each scheduling module can be coordinated according to the upstream and / or downstream operation plans, that is, when compiling or adjusting the operation plan of each section, it is compiled or adjusted according to the production plan of the section and its upstream and / or downstream operation plans. Specifically, the steel casting dynamic scheduling module is used to compile or adjust the steel zone operation plan of the steel zone according to the production plan; the iron and steel dynamic scheduling module is used to compile or adjust the iron zone operation plan of the iron zone according to the production plan and the steel zone operation plan; the casting and rolling dynamic scheduling module is used to compile or adjust the casting and rolling operation plan of the casting and rolling section according to the production plan and the steel zone operation plan, thereby realizing the coordinated scheduling of the iron zone, the steel zone, and the casting and rolling section.

[0040] Among them, the iron area operation plan includes: iron distribution plan, ladle distribution plan and ladle turnover plan; the steel area operation plan includes: molten steel production plan, molten steel transfer plan and ingot cutting plan; the casting and rolling operation plan includes: ingot warehousing and rolling plan.

[0041] The integrated dynamic scheduling system of the embodiment of the present invention receives the production plan formulated by the planning system to schedule the production process according to the production plan, wherein the production plan includes a rolling plan, a casting plan, a furnace plan and an iron plan.

[0042] like Figure 3 As shown, the iron and steel dynamic scheduling module compiles the iron distribution plan, package distribution plan and molten iron turnover plan according to the iron schedule in the production plan and the downstream molten steel production plan scheduling requirements, and manages the rhythm of molten iron production and transportation to the steel area through the molten iron production plan and molten iron operation plan; the steel casting dynamic adjustment module compiles the molten steel production plan, molten steel transfer plan and billet cutting plan according to the furnace schedule and pouring schedule in the production plan to control the production of molten iron to molten steel, the operation of molten steel and the cutting of billets; the casting and rolling dynamic adjustment module compiles the billet in and out storage plan and the rolling plan of the finished product according to the billet cutting plan. This embodiment realizes the integrated scheduling of the production process and opens up the whole process of material production changes through the coordinated scheduling of the iron and steel dynamic scheduling module, the steel casting dynamic scheduling module and the casting and rolling dynamic scheduling module.

[0043] In some embodiments, when the steel casting dynamic scheduling module adjusts the steel area operation plan, the iron-steel dynamic scheduling module dynamically updates the upstream iron area operation plan in real time according to the steel area operation plan, and the casting and rolling dynamic scheduling module dynamically updates the downstream casting and rolling operation plan in real time according to the steel area operation plan, thereby achieving synchronous adjustment of the iron area, steel area and casting and rolling sections.

[0044] For example, when the downstream molten steel production plan is adjusted, all operation plans in the iron zone will be adjusted to the optimal solution accordingly. In this embodiment, the furnace plan and the casting plan are the central links of the integrated scheduling of iron, steel and rolling. The upstream and downstream are connected with the three modules of dynamic scheduling of iron and steel, dynamic scheduling of steel casting, and dynamic scheduling of casting and rolling. Every time the production plan is adjusted, the upstream iron distribution plan, the package distribution plan and the iron ladle turnover plan will be adjusted synchronously, and the downstream billet storage plan and rolling plan will be updated.

[0045] In some embodiments, when the job plan is completed, the dynamic scheduling module sends the specific data of the job plan to the designated equipment to control the equipment to execute the specific production plan. The data acquisition and transmission module collects performance information such as production performance and logistics performance during the production process to facilitate the judgment of the degree of deviation in the execution of the job plan and the degree of impact of event information on the job plan. The data acquisition and transmission module is also used to timely update the information of the executed jobs. The dynamic scheduling module dynamically adjusts the relevant job plans based on the information of the executed jobs.

[0046] Among them, production performance information refers to all production events, measurement data and related reports that occur in the overall production process of iron-steel-rolling. The data acquisition and transmission module receives the corresponding event data through data docking with the on-site secondary equipment, etc., and records and uses the data. Production performance information mainly includes performance information such as event triggering station, time, composition, temperature, etc. Logistics performance information refers to data information on the turnover of related materials such as locomotives and containers, including key data such as locomotive number, container number, location, weight, time, etc.

[0047] In some embodiments, when there is a deviation between actual production performance and the production plan, the dynamic scheduling module is also used to adjust the job plan in real time, so as to realize dynamic adjustment of the production process at any time, optimize the production rhythm, avoid major disturbances in the production process, overcome disturbance factors in the production process, and dynamically manage and control the production process in a closed loop.

[0048] Specifically, the dynamic scheduling module is used to judge the disturbance factors that cause deviations in combination with the process rule library, issue early warning prompts for deviation information, and make real-time dynamic adjustments to the operation plan based on the disturbance factors to reduce deviations and avoid major disturbances in the production process. The disturbance factors include at least one of time deviation, temperature deviation, quality abnormality, and equipment failure, such as time advance or delay, substandard temperature, substandard quality, etc.

[0049] For example, when the actual iron-making performance of the iron zone deviates from the iron-making plan, the steel casting dynamic scheduling module will dynamically schedule the downstream molten steel production plan in real time to the optimal solution.

[0050] In an embodiment of the present invention, the integrated scheduling system can classify and analyze the disturbance factors of the operation plan in combination with the process rule library, and provide optimization and adjustment measures for each disturbance, so that the operation plan can be optimized and adjusted, the optimal production plan can be calculated and the operation plan can be updated in real time to cope with various changes and risk issues in the production process.

[0051] In some embodiments, when an abnormal working condition occurs (for example, equipment failure, etc.), the data acquisition and transmission module is also used to receive abnormal working condition information, and the dynamic scheduling module is used to recompile the operation plan based on the abnormal working condition information and the information of the operation that has been executed, so as to realize the rescheduling of production when the production process is abnormal. Exemplarily, for emergency events such as equipment failure, the integrated scheduling system supports the dispatcher to maintain abnormal equipment failure information. After the data acquisition and transmission module receives the abnormal equipment failure information updated by the dispatcher, the dynamic scheduling module recompiles the operation plan based on the abnormal equipment failure information and the information of the operation that has been executed to cope with emergencies and realize the manual emergency intervention of the dispatcher.

[0052] In some embodiments, when the production plan is adjusted, the dynamic scheduling system is also used to dynamically adjust the operation plan of each section in real time according to the adjusted production plan and the information of the executed operations, so as to realize intelligent production scheduling.

[0053] When adjusting the operation plan, the dynamic scheduling module can adjust the operation time and duration, adjust the production process path, and adjust the transportation time.

[0054] In addition, the dynamic scheduling module can also be used to schedule abnormal production plans (for example, re-melting, etc.).

[0055] In some embodiments, the integrated scheduling system further includes: an overall display and evaluation module, which can exchange information with the dynamic scheduling module and the data acquisition and transmission module, and receive the operation plan compiled by the dynamic scheduling module and the production performance and logistics performance collected by the data acquisition and transmission module. The overall display and evaluation module is used to dynamically display the operation plan of the iron area, steel area, and casting and rolling section in real time, as well as data acquisition, production performance, and logistics performance, so as to realize the visualization and digitization of the whole process production, display the operation production process in multiple dimensions, and assist in production monitoring, so as to optimize and adjust the operation plan and help solve unexpected problems.

[0056] Specifically, the overall display and evaluation module can intuitively display the compiled or adjusted work plan in the form of a Gantt chart, making it convenient for dispatchers to view, edit and confirm the work evolution compiled by the system. In addition, the overall display and evaluation module is also used to display the production performance, logistics performance and other performance information of the production site to monitor the production process and grasp the production rhythm.

[0057] In some embodiments, the overall display and evaluation module is used to compare actual production performance with the production plan to evaluate whether the production plan is reasonable and provide a basis for optimizing the plan for adjusting the plan.

[0058] In some embodiments, the overall display and evaluation module is also used to determine KPI indicators based on production performance and logistics performance analysis to conduct comprehensive indicator evaluation of the production process's efficiency, output quality, resource utilization, environmental protection, etc. The embodiments of the present invention collect all key data in the production process, and use the overall display and evaluation module to integrate and sort the data to conduct a comprehensive evaluation of the KPI indicators, which helps to analyze the influencing factors in the production process and diagnose the causes of problems in the production results.

[0059] Specifically, for the ladle, the overall display and evaluation module can collect statistics on data in dimensions such as turnover rate, temperature, and time to judge production efficiency; for the steel area, the overall display and evaluation module can analyze the production steps of each process according to dimensions such as time, steel type, process path, composition, and temperature to locate factors affecting production; for the entire iron and steel rolling production process, the overall display and evaluation module can collect statistics on the degree of continuity of the production process, the ferrite flow rate, and the temperature curve to measure the overall production efficiency of the steel plant.

[0060] In an embodiment of the present invention, the overall display and evaluation module can conduct multi-level, multi-perspective, and multi-scenario statistical analysis from point to surface, from single dimension to multi-dimensional. It can analyze the production data of a single process as well as the production process of the entire process, so as to locate the production shortcomings in the production process and put forward continuous improvement suggestions for improving production efficiency.

[0061] The iron-steel-rolling integrated scheduling system of the present invention can integrate the continuous / intermittent iron-steel-rolling production process, breaking the traditional production and management mode, optimizing the operation scheduling and intelligent scheduling through simulation, improving the green production level, and realizing intelligent prediction, intelligent decision-making and intelligent analysis. Specifically, the integrated scheduling system can automatically compile and optimize the operation plan on the basis of meeting the requirements of the process rule library, changing the traditional on-site scheduling mode and greatly shortening the on-site scheduling time, from hours to seconds.

[0062] In addition, compared with the singleness of manual scheduling goals, the integrated scheduling system incorporates the process rule library for production scheduling, which can consider factors such as production sequence, energy consumption, equipment, logistics, etc. and give the optimal combination plan, which is more accurate, comprehensive and intelligent than manual scheduling.

[0063] In the present invention, the production scheduling results are displayed through the steel rolling Gantt chart, so as to realize the visualization and digitization of the whole process production, display the operation production process in multiple dimensions, realize the production with stable process, smooth interface and timely regulation, and support the continuous, compact, dynamic and orderly operation of the process.

[0064] In addition, the embodiment of the present invention also provides an integrated scheduling method for iron and steel rolling production, which can be implemented by using the scheduling system of the above embodiment, such as Figure 4 As shown, the method specifically comprises the following steps:

[0065] (1) Receive steel production plans in real time;

[0066] (2) according to the production plan and process rules, coordinate the production processes of the iron zone, steel zone and casting and rolling section, and prepare the operation plans of the iron zone, steel zone and casting and rolling section;

[0067] (3) Real-time collection of production and logistics performance during the production process;

[0068] (4) According to the actual production performance, logistics performance and the process rule requirements, the operation plan of the iron zone, steel zone and casting and rolling section is adjusted dynamically in real time.

[0069] Among them, the production plan includes furnace plan, casting plan, rolling plan, etc.

[0070] like Figure 4 As shown, after receiving the production plan, the operation plans of the three sections of iron and steel, steel casting, and cast-rolling are compiled according to the production plan and process rules, and the operation plan of the entire process of iron and steel rolling production is dynamically simulated to coordinate and match the operation plans of each section. Specifically, the production processes of the iron and steel interface, steel casting interface, and cast-rolling interface are simulated through the iron and steel dynamic scheduling module, the steel casting dynamic scheduling module, and the cast-rolling dynamic scheduling module to optimize the operation plan of each section, so as to meet the delivery date, reduce the generation of waste materials, reduce inventory, reduce the number of equipment changes, reduce the idle time of bottleneck equipment, and reduce energy consumption.

[0071] like Figure 4 As shown in the figure, when the work plan is completed, the work plan will be displayed in the Gantt chart and issued to the production site. During the production process, the production performance and logistics performance of the production site are collected in real time to monitor the production site for abnormalities. When an abnormality occurs at the production site, such as quality abnormality, time deviation, temperature deviation, and equipment failure, the work plan is dynamically adjusted according to the production performance and logistics performance, thereby optimizing the scheduling plan, optimizing the production rhythm, and overcoming the disturbance factors in the production process.

[0072] Specifically, when monitoring abnormalities at the production site, the Gantt chart (including: steel Gantt chart, steelmaking continuous casting Gantt chart, casting and rolling Gantt chart) can be compared with the actual production performance and logistics performance, and the operation time, operation duration, transportation time, etc. of each workstation can be compared. If time deviation occurs, the operation plan can be dynamically adjusted. The actual production performance and logistics performance can also be compared with the production plan and process rules. If abnormalities such as quality abnormalities and temperature deviations occur, the operation plan can be dynamically adjusted.

[0073] In some embodiments, Figure 4 As shown, the production plan can also be evaluated. By comparing the production plan with the actual production performance, it can be judged whether the production plan is reasonable, providing a basis for optimizing the production plan.

[0074] In some embodiments, Figure 5 As shown, when simulating the entire iron and steel rolling production process to prepare or adjust the operation plan, dynamic simulation optimization can be performed based on the production plan, process rule library and simulation parameter table.

[0075] Among them, the simulation parameter table refers to the relevant parameters of the simulation model extracted through the scene analysis of the actual production process of the factory, including: equipment information (including the number, type and working capacity of equipment such as converters, refining furnaces, and continuous casting machines), process paths, production capacity (production capacity and working restrictions of each equipment, such as the pulling speed of the continuous casting machine and the processing cycle of the converter), material flow (including the transportation of molten steel between different processes, such as the generation law of overhead crane transportation tasks) and time parameters (including the operation time, waiting time and possible delays of each process). The dispatcher can configure the parameters of the simulation parameter table according to the actual historical production process.

[0076] like Figure 5 As shown in the figure, when the operation plan is determined, the turnover scheduling plan for the crane, ladle, and iron ladle is generated at the same time to realize the logistics support such as locomotive scheduling in the actual production process. After the operation plan and the turnover scheduling plan are all generated, they are issued to the actual production site for execution, and the production site produces according to the operation plan and the turnover scheduling plan. However, deviations may occur in the specific production process, so it is necessary to monitor the production performance, logistics performance, and abnormal working conditions in real time during the production process. When deviations and abnormal working conditions occur, the operation plan is adjusted dynamically in real time to optimize the scheduling plan according to the actual production situation.

[0077] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
