Description

Technical Field

[0001] The present application relates to the field of big data, and specifically to a method and device for generating a graphical steelmaking scheduling Gantt chart. Background Art

[0002] For the entire production process of iron and steel enterprises, the steelmaking-refining-continuous casting process link is the core and bottleneck in the entire iron and steel production and manufacturing process. The efficiency of the steelmaking-continuous casting production link is crucial for ensuring the reasonable progress of the entire iron and steel production and manufacturing process. In modern enterprise production, the manufacturing execution system MES plays a connecting role between the enterprise ERP system and the production process control PCS, and the production scheduling system is the core function of the MES system. Achieving efficient and reasonable scheduling of the iron and steel production process can rationally and efficiently utilize enterprise resources and improve the production efficiency and benefits of the enterprise.

[0003] Currently, most steel mills' production scheduling mainly relies on form-based production scheduling operations. The convenience and intuitiveness of system operations are poor. The operation volume of each device cannot be intuitively displayed; the operation time relationship between devices cannot be intuitively displayed; when there is an operation time conflict between devices, it cannot be intuitively displayed; since the operation times of each process are different during the process from the converter to the smelting operation, and the operation volume of the previous process is greater than that of the subsequent process, resulting in congestion in the subsequent process operation, the tabular data cannot be intuitively displayed; when there are actual changes from the plan during the operation process, reducing or increasing processes can be achieved through buttons, and even after the adjustment is completed, the adjustment result cannot be intuitively displayed; when there is a conflict in the time of a single process, it is simply impossible to make adjustments in the table, and when making adjustments in the form of a Gantt chart, adjustments can be made by dragging.

[0004] Due to the above reasons, many software companies have developed Gantt charts to adjust steelmaking scheduling in response to the needs of steel mills for steelmaking scheduling adjustments. However, most of the currently developed Gantt chart adjustments completely rely on operators to make adjustments based on on-site real-time data according to their operation experience. If the operator lacks experience, or encounters operation fatigue, or the real-time data is obtained untimely or incompletely, resulting in adjustment errors, it will affect the smooth progress of production.

[0061] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0062] In the technical solutions of the present application, the acquisition, storage, use, processing, etc. of data all comply with the relevant regulations of laws and regulations.

[0063] The Gantt chart was proposed by the scientific management master Henry Laurence Gantt (1861 - 1919) in 1917 and is a very effective tool for solving the problem of workshop production sequencing. The Gantt chart establishes a time-based network that can intuitively reflect the construction period, progress, logical relationship, and critical path of workshop tasks. It plots some completed work and the work to be done on a time axis (horizontal axis), and plots the people or equipment undertaking each work on the vertical axis, graphically presenting the complex data of production scheduling in a simple and intuitive graphical way, making the production plan arrangement of the workshop clear at a glance and becoming an effective tool for understanding the overall situation and arranging the production progress of the workshop.

[0064] In one embodiment, referring to Figure 1 , in order to be able to automatically update the Gantt chart using intelligent algorithms based on the real-time data of equipment operations and reduce manual adjustment of the Gantt chart, the present application provides a method for generating a graphical steelmaking scheduling Gantt chart, including:

[0065] S101: Perform standard maintenance operations and static scheduling operations on the obtained steelmaking process data to generate steelmaking process drawing data;

[0066] S102: Generate an initial steelmaking scheduling Gantt chart based on the steelmaking process drawing data;

[0067] S103: Dynamically adjust the initial steelmaking scheduling Gantt chart using a pre-constructed Gantt chart automatic adjustment algorithm to obtain a steelmaking scheduling Gantt chart.

[0068] It can be understood that the embodiments of this application are implemented based on the powerful C# language + WebGL + Oracle. It uses WebGL drawing technology for the display and front-end adjustment of Gantt charts. Among them, WebGL can achieve cross-platform applications and run in various browsers without installing additional software or plugins. WebGL has high performance and can utilize the GPU for hardware acceleration to achieve efficient graphics rendering. WebGL has good flexibility and supports various 3D model formats, such as OBJ, FBX, etc., which can meet the requirements of various application scenarios. WebGL can perform real-time interaction, achieve real-time graphics rendering and user interaction, and provide a smooth user experience. C# obtains real-time scheduling plan data from Oracle based on the API technology of the industrial Internet platform (the execution entity in the embodiments of this application), and after calculation using intelligent algorithms, delivers it to the front-end WebGL for Gantt chart display.

[0069] Among them, the functions of the Gantt chart are mainly reflected in: plan management, scheduling management, and process management. First, production plan: Production is inseparable from plans, and plans are generated from customer orders. The Gantt chart reflects plan process monitoring and adjustment for plan management, and the scheduling operator adjusts the plan according to the actual situation on site. Secondly, scheduling management: The core of the Gantt chart function. It adjusts the production plan based on the actual production situation to meet the actual situation on site. Finally, process management is further divided into: quality control, equipment monitoring, process assistance, etc. Among them, quality monitoring is to control the production quality according to the real-time production process quality data, such as: real-time production temperature, composition, etc.; equipment monitoring is to monitor the equipment operation time and equipment status; process assistance is to monitor with the help of digital process systems, standards and other production process information. Combining plan management, scheduling management, and process assistance, with plan management as the basis and process information as the assistance, scheduling management is completed.

[0070] In the embodiments of this application, the Gantt chart can be seamlessly docked with the industrial Internet platform. Since its data tables, Gantt chart display screens, and API services are independent of the industrial Internet platform, it can be smoothly migrated to other projects.

[0071] In actual working conditions, there are multiple objectives and multiple constraints in steelmaking scheduling, resulting in complex calculations. The multiple objectives are reflected in the steelmaking production process, where the molten steel composition, molten steel temperature, and operation time must all meet the standards; the multiple constraints are reflected in that the operation time of each process is less than the standard operation time, the moving time between processes is less than the standard moving time, and the continuous casting cutting volume is maximized. Only through dynamic scheduling can the system requirements be met.

[0072] In addition, the steelmaking production process involves many steps, has strong randomness, and is complex to model. The steelmaking production process not only includes main steps such as converters / electric furnaces, LF / RH / VD, continuous casting, etc., but also many auxiliary steps. When modeling, it is necessary to fully consider the coordination between these steps. During the steelmaking production process, regardless of the processes of converters / electric furnaces, LF / RH / VD, continuous casting, etc., the operation time cannot be determined. In addition, the time when the molten steel arrives at any process is also random. These uncertain factors cause the difficulty of the modeling work to increase exponentially.

[0073] Based on complex modeling and calculations, the method provided by the present invention successfully solves the technical problem of steelmaking production scheduling. Refer to Figure 14 , starting from receiving tasks (including: weight, specifications, steel grades, delivery dates, etc.), determine the heat number according to the heat number preparation quantity; determine the casting number according to the mixed casting standard; perform static scheduling according to the operation quantity of the process, the standard time of the process, the process maintenance plan, and the delivery time. Based on the static scheduling, display the operation plan in a Gantt chart, collect real-time data (composition information, temperature information, operation time, etc.) in a timely manner, input the real-time data into the model, start the model for calculation, and adjust the original Gantt chart; display the calculation results on the Gantt chart again, and complete the dynamic scheduling of steelmaking production through the human-machine interface, static adjustment, dynamic adjustment, case library, etc.

[0074] Specifically, refer to Figure 12 , the upper part of the interface is the tool area. Using the buttons in the tool area, plan change operations such as heat number exchange, heat number exchange, molten steel return to the furnace, cancel LF, plan release, cancel release, tundish quick change, change of fixed length, change of steel grade, tilting furnace, etc. can be performed, and the casting number color changes.

[0075] The left side of the interface is the process area, which displays the process types and the number of processes in the steel plant. The process types and the number of processes are configured according to the actual processes of each steel plant in the process configuration table of the database.

[0076] Figure 13This is the Gantt chart data area. The entire data area fully displays the Gantt chart data. Above the data area is the time axis, which starts from the time selected by the time control in the tool area and extends 24 hours to the right. The time axis is divided into units of 30 minutes, and each division segment displays the time in the "hour:minute" mode. Each 30-minute segment is further divided into units of 5 minutes, and each 5-minute interval is indicated by a vertical line. In the data area, each process is identified by a horizontal line, and the processes are arranged from the converter to the continuous casting from top to bottom. Each colored rectangular block in the data area represents a heat. The corresponding time on the left side of the block on the time axis indicates the start time of the heat, and the corresponding time on the right side of the block is the end time of the heat. The length of the block is the operation time of the heat in the current process. Each heat goes through different processes, and different rectangular blocks are drawn on the Gantt chart. The blocks are connected by lines, and the color of the blocks is the same as the color setting of the continuous casting machine in the toolbar. For example, the red vertical line in the Gantt chart area is the current time. The heats to the left of the red vertical line are the heats that have completed the operation, and the completed heats are displayed in white. The heats to the right of the red vertical line are the heats whose operations have not yet started as planned, and the heats straddling the red vertical line are the heats that are currently in operation. When the mouse moves in the Gantt chart area, there is a green vertical line that moves with it, passing through the entire upper and lower areas of the Gantt chart, facilitating the viewing of the accurate start time and end time of each heat.

[0077] As can be seen from the above description, the method for generating a graphical steelmaking scheduling Gantt chart provided by this application can add an automatic coordination algorithm to the Gantt chart based on intelligent manufacturing and static and dynamic scheduling technologies. Based on the real-time data of equipment operations, an intelligent algorithm is used to automatically update the Gantt chart, reducing manual adjustment of the Gantt chart. As much as possible, the Gantt chart automatically adapts to the on-site situation without manual intervention, maximizing the satisfaction of on-site working conditions requirements and responding to the industry development plan and industry development requirements.

[0078] In one embodiment, referring to Figure 2 , before generating the initial steelmaking scheduling Gantt chart based on the steelmaking process drawing data, it further includes:

[0079] S201: Drag and adjust the steelmaking process data;

[0080] S202: Select and adjust multiple heats for the steelmaking process data.

[0081] It can be understood that when dragging and adjusting the time furnace sequence around the current process, the furnace sequence on the right will be adjusted to the right after dropping, or it can also be dropped into the same type of process. For example, the furnace sequence of the converter process can only be dropped into the converter process. When selecting multiple furnace sequences, you can draw a diagonal line on the Gantt chart with the mouse, and the furnace sequences within the rectangular area formed from the upper left corner to the lower right corner of the diagonal line will be selected. Hold down the left mouse button and move it to the right or left, and all the selected furnace sequences will move with the mouse. Right-click on a certain furnace sequence, and all the furnace sequences from the converter to the continuous casting of this furnace sequence will be selected. Double-click on a certain furnace sequence with the right mouse button, and all the furnace sequences corresponding to the casting of this furnace sequence will be selected.

[0082] After the execution entity of the embodiment of the present application receives the instruction corresponding to the drag and adjustment or the instruction corresponding to the furnace sequence selection, it can perform corresponding actions.

[0083] As can be seen from the above description, the method for generating a graphical steelmaking scheduling Gantt chart provided by the present application can perform drag and adjustment and multi-furnace sequence selection adjustment on the steelmaking process data before generating the initial steelmaking scheduling Gantt chart based on the steelmaking process drawing data.

[0084] In one embodiment, refer to Figure 3 , performing standard maintenance operations and static scheduling operations on the obtained steelmaking process data to generate steelmaking process drawing data includes:

[0085] S301: Perform standard maintenance operations on the obtained steelmaking process data to generate the steelmaking process drawing data; wherein, the standard maintenance operations include maintaining steel grades, specifications, corresponding continuous casting, furnace capacity standards, process capacity, billet specifications, process operation time, and inspection plan time;

[0086] S302: Perform static scheduling operations on the obtained steelmaking process data to generate the steelmaking process drawing data; wherein, the static scheduling operations include determining billets and furnace sequences based on process path standards, furnace capacity standards, and process operation time standards; determining the process path according to billets, furnace sequences, and the preparation of furnace casting plans; performing calculations for allocating furnace sequence smelting workstations; and generating a steelmaking production operation plan.

[0087] It can be understood that when performing standard maintenance of the process path, it is necessary to obtain whether the steel grade + specification has passed through RH (Ruhstahl hausen Process, vacuum degassing) and which continuous casting it has passed through; it is necessary to obtain the furnace capacity standard, specifically to obtain the capacity of a certain process or the billet specification cut by a certain continuous casting; it is necessary to obtain the process operation time, specifically to obtain the operation time of the steel grade + specification in a certain process; it is necessary to obtain the maintenance plan, specifically to obtain the inspection plan time of the main process.

[0088] When performing static scheduling, it is necessary to receive planning information, including: steel grade, specification, fixed length, weight, delivery date, etc. Next, based on the process route standard, furnace capacity standard, and operation time standard of each process, blank determination and furnace number determination are realized; according to the furnace number, the furnace casting plan is determined, the process route is determined, the smelting workstations of the furnace number are allocated and calculated, the start time and end time of each process are determined, and a steelmaking production operation plan is generated together with the steelmaking production process regulations, including the furnace number production operation plan and the blank cutting plan.

[0089] As can be seen from the above description, the method for generating a graphical steelmaking scheduling Gantt chart provided by this application can perform standard maintenance operations and static scheduling operations on the obtained steelmaking process data to generate steelmaking process drawing data.

[0090] In one embodiment, refer to Figure 4 , the Gantt chart automatic adjustment algorithm includes: a dynamic adjustment algorithm; using the pre-constructed Gantt chart automatic adjustment algorithm to dynamically adjust the initial steelmaking scheduling Gantt chart to obtain the steelmaking scheduling Gantt chart, including:

[0091] S401: Determine the start time, completion time, processing time of the current process and the current machine load;

[0092] S402: Select the execution machine according to the pre-determined selection strategy, the start time, completion time, processing time and the current machine load;

[0093] S403: Output the steelmaking scheduling Gantt chart according to the selected execution machines.

[0094] It can be understood that during the operation of the system, the system uses the dynamic scheduling algorithm, rule library, and case library to dynamically adjust the steelmaking plan, and displays the adjustment results on the Gantt chart in a timely manner. Subsequently, the operator corrects the dynamic adjustment results made by the system according to work experience and production conditions. When the operator makes corrections, the system saves the correction results to the case library, achieving the effect of self-learning of the dynamic algorithm of the steelmaking plan, and continuously improving during the operation of the system.

[0095] First, the drawing process of the initial steelmaking scheduling Gantt chart will be described below.

[0096] First, initialize the position of process equipment: including all converters, LF (laddle refining furnace), RH (Ruhstahl hausen Process, vacuum degassing), and continuous casting, and set the position array of process equipment. Get the planning information, including: furnace number, pouring number, process path, converter start and end time, LF start and end time, continuous casting start and end time, etc. Use the converter start and end time and the converter seat number in the process path to initialize the upper left corner coordinates and operation time of the furnace converter station on the Gantt chart (converted to the width of the furnace rectangle, the furnace rectangle height defaults to a certain value). Similarly, get the upper left corner position and rectangle width of the furnace rectangle in the LF and continuous casting station on the Gantt chart. According to the upper left corner position and width of each rectangle plus the color set by the page user, use WebGL drawing technology to call the function drawAllObj(ctx) to draw the Gantt chart. The variable ctx is the WebGL canvas.

[0097] After obtaining the initial Gantt chart of steelmaking scheduling, real-time dynamic adjustment can be performed. The method of real-time dynamic adjustment at least includes:

[0098] ① When one or more furnaces are selected and the mouse is dragged in the Gantt chart area, the coordinates of the upper left corner of the dragged furnace are changed, the canvas is cleared, and the function drawAllObj(ctx) is called to draw the Gantt chart. When the mouse moves in the Gantt chart area, the coordinates of the mouse in the Gantt chart area change slightly. If there is a selected furnace rectangle, the system will repeatedly clear the canvas and call the function drawAllObj(ctx) to draw the Gantt chart. Since WebGL can interact in real time, it can realize real-time graphics rendering and user interaction, providing a smooth user experience. What the user sees is that when the mouse drags one or more furnaces to move in the Gantt chart area, the picture is very smooth, there will be no delay or freeze, and the picture will not be cleared, and the furnaces and the lines between the furnaces will not be redrawn.

[0099] ② Use dynamic adjustment algorithm for dynamic adjustment, see Figure 15 . Obtain real-time production data, input the real-time steelmaking process data into the dynamic adjustment algorithm, make intelligent plan adjustments, refresh the Gantt chart in real time, and display the Gantt chart adjustment results in a timely manner.

[0100] Specifically, Step 1: Calculate the start time, completion time, processing time, and current machine load of the current process for all available machines for each workpiece in each process. When calculating the start time of the process, it is necessary to compare the completion time (TP) of each process on the workpiece with the completion time (TM) of the previous process processed by the machine. If TM ≥ TP and there is a gap greater than the processing time of the process between TP and TM on the machine, the process can be inserted into the gap, and the start time is the end time of the previous process in the gap; if TM < TP, the start time is TP.

[0101] Step 2: Select a machine. The preferential selection principle is as follows: preferentially select the machine with the minimum completion time; if the completion times are the same, select the machine with the minimum current machine load; if the machine loads are also the same, randomly select a machine. That is, the priority is completion time > machine load.

[0102] Step 3: Determine whether machine selection has been performed for all processes of all workpieces. If it has been selected, end the loop and output the scheduling plan; otherwise, return to Step 1.

[0103] It should be noted that the dynamic adjustment algorithm can use the rules in the rule library for dynamic scheduling calculation. For example:

[0104] 1. In steelmaking scheduling, each workpiece must go through all processes, and any machine in the process can be passed through and only one machine is passed through. Therefore, in Step 1, calculate the start time, completion time, processing time, and current machine load of the current process for all available machines for each workpiece in each process.

[0105] 2. In steelmaking production, high-temperature liquid flows between processes. During the flow process, an appropriate temperature must be ensured. When moving between processes, it cannot stay for too long, and in order to ensure the shortest operation time, therefore, in Step 2, preferentially select the machine with the minimum completion time. If a machine with a larger completion time is selected, it will not only increase the flow time between processes but also increase the overall operation time.

[0106] 3. Because each workpiece must go through all processes, in Step 3, it is necessary to ensure that all workpieces have gone through all processes before ending the loop, otherwise the algorithm cannot end.

[0107] As can be seen from the above description, the method for generating a graphical steelmaking scheduling Gantt chart provided by this application can dynamically adjust the initial steelmaking scheduling Gantt chart using the pre-constructed Gantt chart automatic adjustment algorithm to obtain the steelmaking scheduling Gantt chart.

[0108] In one embodiment, refer to Figure 5, the Gantt chart automatic adjustment algorithm includes: a case matching algorithm; the use of the pre-constructed Gantt chart automatic adjustment algorithm to dynamically adjust the initial Gantt chart of steelmaking scheduling to obtain the Gantt chart of steelmaking scheduling, including:

[0109] S501: Compare the drawing data of the steelmaking process with the historical drawing data of the steelmaking process recorded in the case library to obtain the corresponding similarity;

[0110] S502: If the similarity meets the preset threshold, adjust the initial Gantt chart of steelmaking scheduling according to the historical Gantt chart corresponding to the historical drawing data of the steelmaking process to obtain the Gantt chart of steelmaking scheduling.

[0111] It can be understood that after obtaining the initial Gantt chart of steelmaking scheduling, real-time dynamic adjustment can be performed. The method for real-time dynamic adjustment at least further includes:

[0112] Perform dynamic adjustment using the case matching algorithm, see Figure 15 . Obtain production real-time data, input the real-time obtained steelmaking process data into the case library and the rule library, perform intelligent plan adjustment, the Gantt chart is refreshed in real time, and the adjustment result of the Gantt chart is displayed in time.

[0113] Specifically in implementation, it can be executed according to the following steps.

[0114] Step 1: Compare the current machine status.

[0115] The current machine status refers to the operation time of all current machines and the estimated end time;

[0116] Search in the case library with the current machine status and the machine status in the case library. If the number of searched cases is greater than 0, the machine status comparison is successful, and go to Step 2; otherwise, the case library solution fails and return;

[0117] Step 2: Compare the task status.
