Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of metallurgical control, and particularly relates to an iron ladle dynamic management and control system and method applied to an iron-steel interface region. BACKGROUND
[0002] The iron-steel interface region is an important transition region for material flow exchange between the iron region and the steel region, and is also a key link for ensuring normal production of the two regions. The steel region has a demand for hot metal, and the iron region is responsible for supplying hot metal. Since the iron region is intermittent operation and the steel region is continuous production, under the production process of the iron region "pushing" and the steel region "pulling", the production rhythm of the two regions must be precisely matched, which inevitably faces a series of challenges, so that the iron-steel interface region becomes a region where logistics scheduling conflicts are prone to occur.
[0003] Nowadays, the importance of continuous production has been widely recognized, and it is necessary to uniformly allocate from the perspective of the whole production line rather than a single process, coordinate the process rhythm, and improve the process connection ability to ensure the coordinated operation of the whole production line. While ensuring continuous production, the task load and operation rate of the transportation tools such as iron ladles, overhead cranes, locomotives and carriages also need to be considered. At present, the "one ladle to the end" mode has been popularized in hot metal transportation in many iron and steel enterprises. Since the stable operation of the iron ladle in the iron-steel interface region directly affects the turnover efficiency, it must be consistent with the rhythm of the ironmaking and steelmaking regions, which is more stringent than the traditional mode for the production scheduling of the iron ladle.
[0004] However, the existing system or method for scheduling the iron ladle logistics operation in the iron-steel interface region still has many problems: the data information of different processes cannot be effectively integrated to solve the problem, and the unclear rules cause the influence of human factors to increase, resulting in confusion; the limitation of space or layout leads to mixed use of lines, causing uneven utilization of different iron ladle lines and increasing the waiting time between cross-operation tasks; and the like.
[0005] Therefore, in order to meet the requirement of continuous production of the steel production process, the iron ladle logistics scheduling in the iron-steel interface region needs to be optimized. SUMMARY
[0006] In view of the above analysis, the embodiments of the present application aim to provide an iron ladle dynamic management and control system and method applied to an iron-steel interface region, at least to solve one of the following problems existing in the existing iron ladle logistics scheduling system or method for the iron-steel interface region: 1. The existing iron ladle logistics scheduling system or method for the iron-steel interface region cannot effectively plan the space or layout, leading to mixed use of lines, causing uneven utilization of different iron ladle lines and increasing the waiting time between cross-operation tasks; 2. The existing iron ladle logistics scheduling system or method for the iron-steel interface region cannot effectively integrate the data information of different processes, and the unclear rules cause the influence of human factors to increase, resulting in confusion and low production efficiency.
[0007] The objective of this invention is mainly achieved through the following technical solutions:
[0008] This invention provides a dynamic control system for ladles applied to the iron-steel interface area, including an iron zone information module, a dynamic adjustment module, a dynamic area control center, a real-time information tracking module, and a steel zone information module;
[0009] The dynamic area control center includes a re-packet caching module, a re-packet input module, an empty packet return module, and an empty packet caching module; these modules are connected via a network.
[0010] The ladle dynamic control system sets different ladle functional areas within the steel interface area, including a heavy ladle buffer functional area, a heavy ladle loading functional area, an empty ladle return functional area, and an empty ladle buffer functional area.
[0011] Among them, the total number of lines managed by the heavy package infeed function module and the empty package return function module is ≥2, and the number of empty slots that can accommodate iron packages on each line is ≥1.
[0012] Furthermore, the iron ore zone information module is used to acquire iron ore production plans and iron ore transportation information, and to realize information interaction with other modules in the system and the iron ore zone;
[0013] The dynamic adjustment module is used to identify information input, perform dynamic matching calculations, and implement matching adjustment schemes.
[0014] The dynamic area control center, based on real-time data from the real-time information tracking module, issues instructions to allocate transportation vehicles to enter and exit each iron ladle functional area, completing the placement and hoisting of the iron ladles.
[0015] The real-time information tracking module is responsible for comprehensively tracking and monitoring the real-time information of ladles, molten iron and transportation vehicles in the iron-steel interface area, and providing data support for other modules.
[0016] The steel zone information module is used to obtain steelmaking production plans and steelmaking area transportation loads, and to realize information interaction with other modules in the system and the steel zone.
[0017] Furthermore, the heavy package feeding function module is responsible for recording, analyzing and managing the data in the heavy package feeding function area, and maintaining information exchange with the real-time information tracking module;
[0018] The heavy package loading module executes the scheduling instructions of the dynamic area control center to complete tasks such as the entry and exit of transport vehicles, the arrival of heavy packages, and the hoisting of heavy packages.
[0019] The data in the heavy package loading area includes parameters such as loading line, loading position, quantity of heavy packages, empty package return position, weighing, and transport vehicle status.
[0020] Furthermore, the empty packet return function module is responsible for recording, analyzing and managing the data in the empty packet return function area, and maintaining information interaction with the real-time information tracking module;
[0021] The empty package return function module executes the scheduling instructions of the dynamic area control center to complete the tasks of transport vehicle entry and exit, empty package loading, and empty package return.
[0022] The data in the empty package return function area includes parameters such as return route, return location, number of empty packages, return location of empty packages, and vehicle status.
[0023] Furthermore, the repackage caching function module is responsible for recording, analyzing and managing the data within the repackage caching function area, and maintaining information interaction with the real-time information tracking module;
[0024] The repacket caching function module executes the scheduling instructions of the dynamic regional control center to complete the repacket loading and repacket transportation tasks;
[0025] The data within the repacket caching function area includes information on cache location and quantity, repacket location, and repacket quantity.
[0026] Furthermore, the empty packet caching module is responsible for recording, analyzing, and managing the data within the empty packet caching function area, and maintaining information interaction with the real-time information tracking module;
[0027] The empty package caching module executes the scheduling instructions of the dynamic regional control center to complete the empty package loading and empty package delivery tasks;
[0028] The data within the empty packet caching function area includes information on cache location and quantity, empty packet location, and empty packet quantity.
[0029] This invention also provides a method for dynamic control of ladles applied to the steel-iron interface area, which is implemented through the aforementioned ladle dynamic control system, including the processes of heavy ladle entry initiation, entry path scheduling, heavy ladle hoisting execution, heavy ladle hoisting removal, empty ladle return scheduling, and empty ladle return to the iron zone.
[0030] Furthermore, the process of initiating the heavy package ironing process includes: the dynamic area control center acquiring and analyzing information from each module of the system, and after receiving the steel production plan and iron arrival information from the ironing area, it initiates the heavy package ironing task based on the ironing time of the steeling area, whether the heavy package ironing functional area and the heavy package buffer functional area have the receiving conditions, and directs the heavy packages outside the iron-steel interface area to enter the iron-steel interface area.
[0031] The railway entry path scheduling includes: the dynamic area control center makes conditional judgments and completes the railway entry path scheduling based on the information of the heavy package entry function module and the number of heavy packages entering the railway.
[0032] The condition judgment rule is to compare the empty iron feeding positions in the heavy package feeding function area with the number of heavy packages entering the iron-steel interface area to determine the heavy package storage location and entry route.
[0033] If the number of empty iron-feeding positions in the heavy package iron-feeding functional area is greater than or equal to the number of heavy packages entering the iron-steel interface area, the heavy packages will drive directly into their positions and the transport vehicle will wait for new dispatch instructions.
[0034] If the number of empty loading positions in the heavy package loading area is less than the number of heavy packages entering the steel-iron interface area, some heavy packages will enter empty loading positions. The remaining heavy packages without loading positions will be transported by transport vehicles to the heavy package buffer area for temporary storage and to await instructions. When the empty loading positions in the heavy package loading area become available again, the heavy package loading module will send a signal to the dynamic area control center. The dynamic area control center will then dispatch transport vehicles to move the heavy packages from the heavy package buffer area to the heavy package loading area.
[0035] Furthermore, the heavy package hoisting execution includes: after the heavy package arrives at the target location in the loading area, the heavy package loading module sorts the packages according to information such as arrival time, route, specific location of the heavy package on the same route, and whether the route corresponds to the steel mill's process, to determine the priority order for supplying heavy packages to the steel area; the steel area information module immediately transmits the heavy package information of the loading area to the steel area, which then allocates transportation vehicles to carry out the heavy package transportation task; if the steel area cannot receive the heavy package at this time, the heavy package continues to wait;
[0036] The removal of the heavy package includes: the heavy package is lifted by the transport vehicle and removed from the heavy package loading area. After that, the real-time information tracking module immediately updates the vacancy information and synchronizes it to the dynamic area control center.
[0037] Furthermore, the empty package return scheduling includes: the steel area information module continuously acquires information such as the status of steel area ladles, process progress, and completion of iron exchange, and transmits it to the dynamic area control center in real time;
[0038] When the empty package return function area is ready to receive, the steel area information module immediately transmits the information to the steel area, and the steel area dispatcher directs the transportation vehicle to transport the empty package to the empty package return function area.
[0039] When the empty package return position in the empty package return function area is not ready to receive, the steel area information module immediately transmits the information from the empty package buffer function module to the steel area. The steel area dispatcher then directs the transport vehicles to temporarily store the empty package in the empty package buffer function area. When the empty package return position in the empty package return function area is ready to receive, the empty package return function module sends a signal to the dynamic area control center. The dynamic area control center then dispatches the empty package from the empty package buffer function area to the empty package return function area.
[0040] The empty package return to the iron zone includes: when the empty package in the empty package return function area completes the loading action and meets the conditions for returning to the iron zone, the empty package return function module sends a signal to the dynamic area control center, and the dynamic area control center immediately starts the empty package return task and directs the transport vehicle to transport the empty package back to the iron zone.
[0041] The railway information module sends information such as empty package information and transportation vehicle information to the railway area.
[0042] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:
[0043] 1. The present invention relates to a dynamic control system for ladles applied to the iron-steel interface area. By setting different functional areas within the iron-steel interface area, the system includes an iron area information module, a dynamic adjustment module, a dynamic area control center, a real-time information tracking module, and a steel area information module connected via a network. This effectively avoids the problem of mutual waiting and interference caused by the mixed use of incoming iron lines and return empty lines, thus ensuring production continuity.
[0044] 2. The ladle dynamic control system of the present invention, applied to the iron-steel interface area, realizes dynamic isolation of the two types of functional line transportation operations by implementing zoned dynamic control of the iron inlet line and the empty return line, which significantly reduces the transportation conflicts within the steel plant and improves the transportation efficiency within the plant.
[0045] 3. This invention uses a dynamic adjustment module in the system to dynamically adjust the line and manage heavy packages. It optimizes the position of heavy packages after they enter the molten iron feeding area and matches them with the steel processing procedures and the capacity of the steel transport vehicles. This makes the transportation process of heavy packages into the steel area more reasonable, shortens the waiting time from the arrival of the heavy package to its hoisting, reduces the temperature drop of molten iron, and reduces energy loss. By dividing different functional areas for molten iron ladles, the risk of conflict between transport vehicles traveling in opposite directions can be eliminated, improving overall safety. By enabling and defining functional tracks, and performing real-time switching of track functions according to the adjustment plan, and real-time allocation of locomotives, frames, and overhead cranes, the scheduling efficiency of transport vehicles can be improved, scheduling operations can be facilitated, waiting time for molten iron ladles can be reduced, and congestion of transport vehicles can be significantly reduced.
[0046] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the description or be learned by practicing the invention.

[0053] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.
[0054] This invention provides a dynamic control system for ladles applied to the iron-steel interface area, including an iron zone information module, a dynamic adjustment module, a dynamic area control center, a real-time information tracking module, and a steel zone information module;
[0055] The dynamic area control center includes a re-packet caching module, a re-packet input module, an empty packet return module, and an empty packet caching module; all modules are connected by a network.
[0056] The ladle dynamic control system sets different ladle functional areas within the iron-steel interface area, including a heavy ladle buffer area, a heavy ladle molten iron feeding area, an empty ladle return area, and an empty ladle buffer area. A heavy ladle refers to a ladle transporting molten iron from the iron zone to the iron-steel interface area, while an empty ladle refers to a ladle returning after being filled with molten iron in the converter. The heavy ladle buffer area is located at the connection point before the ladle is transported from the iron zone to the iron-steel interface area, and the empty ladle buffer area is located at the connection point after the ladle returns from the converter to the iron-steel interface area.
[0057] The iron zone information module is used to obtain iron production plans and iron transportation information, and to realize information interaction with other modules in the system and the iron zone.
[0058] The dynamic adjustment module is used to identify information input, perform dynamic matching calculations, and match adjustment schemes. This module receives information from the dynamic area control center, the real-time information tracking module, the iron zone information module, and the steel zone information module in real time. It performs data analysis and matching calculations on each functional area within the system, generates a match adjustment scheme through dynamic matching calculations, and immediately sends the match adjustment scheme to the dynamic area control center to perform real-time switching of line functions and real-time allocation of transportation vehicles.
[0059] The dynamic area control center, based on real-time data from the real-time information tracking module, issues instructions to allocate transportation vehicles to enter and exit various functional areas to complete the placement and hoisting of iron ladles. At the same time, the dynamic area control center maintains information interaction with the real-time information tracking module and the dynamic adjustment module, records and analyzes iron ladle parameters, including iron ladle serial number, iron ladle position, iron ladle temperature, and iron ladle turnover number, etc.
[0060] The real-time information tracking module is responsible for comprehensively tracking and monitoring the real-time information of ladles, molten iron and transportation vehicles in the iron-steel interface area, and providing data support for other modules.
[0061] The steel zone information module is used to obtain steelmaking production plans and steelmaking area transportation loads, and to realize information interaction with other modules in the system and the steel zone.
[0062] Specifically, the iron zone information module interfaces with the iron zone to obtain molten iron transportation information (i.e., incoming and outgoing molten iron data from the iron-steel interface area). The incoming molten iron data from the iron-steel interface area includes the number of ladles, ladle serial number, ladle turnover times, molten iron temperature, molten iron composition, molten iron volume, and transport vehicle serial number. After obtaining this data from the iron zone, the iron zone information module transmits it to the dynamic area control center. At the same time, after obtaining outgoing molten iron data information from the dynamic area control center, such as ladle serial number, number of ladles, ladle turnover times, and transport vehicle serial number, the iron zone information module transmits the outgoing molten iron data information back to the iron zone.
[0063] Specifically, the steel area information module interfaces with the steel area to obtain data such as the steelmaking production plan, transportation vehicle status, and process times, and transmits this data to the dynamic area control center. Simultaneously, when the module obtains ladle-related information from the dynamic area control center regarding the heavy ladle feeding function area, it transmits this information back to the steel area to coordinate the steel-iron interface area and the steel area in completing the heavy ladle transportation task. The process times include the start and end times of the molten iron receiving process and the start and end times of the converter molten iron charging process.
[0064] Specifically, the real-time information tracking module is responsible for comprehensively tracking and monitoring the real-time information of ladles, molten iron, and transportation vehicles within the iron-steel interface area, and pushing this information to various modules of the system in real time. During the operation of the ladles, the real-time information tracking module continuously interacts with the dynamic area control center, the iron area information module, and the steel area information module, and outputs information about the iron area, steel area, and various functional areas to the dynamic adjustment module in real time.
[0065] Specifically, the heavy-load package loading function module of the dynamic area control center is responsible for recording, analyzing, and managing data within the heavy-load package loading function area, including loading lines, loading positions, quantity of heavy-load packages, empty package return positions, weighing, and transport vehicle status, and maintains information exchange with the real-time information tracking module. This module executes the scheduling instructions of the dynamic area control center to complete tasks such as transport vehicle entry and exit, heavy-load package placement, and heavy-load package hoisting. The specific operation process is as follows:
[0066] The railway line consists of m lines, denoted as a1, a2, ..., a m m≥1; each incoming railway line includes i1, i2, ..., i m Let i1, i2, ..., i be the input positions. m All values are ≥1; The heavy-load loading function module numbers the transport vehicles entering the heavy-load loading function area, sorts them according to task importance based on the current task information of the transport vehicles, and marks parameters such as the entry time, number of uses, and parking position of the transport vehicles to achieve the management of transport vehicles; it numbers the heavy-load packages entering the heavy-load loading function area, sorts them according to information such as waiting time, return position, and molten iron temperature to complete the management of heavy-load packages; it manages each loading line according to the status of transport vehicles, loading positions, and completion of heavy-load tasks, updates the loading line status information, receives adjustment scheme information from the dynamic adjustment module, switches the loading line function in the iron and steel interface area according to instructions, updates the scope of the heavy-load loading function area, and completes the management of loading lines; it issues instructions containing information such as loading lines, transport vehicles, and return positions of heavy-load packages to complete the scheduling execution task.
[0067] The empty package return function module of the dynamic area control center is responsible for recording, analyzing, and managing data within the empty package return function area, including return routes, empty locations, number of empty packages, empty package return positions, and vehicle status, and maintains information exchange with the real-time information tracking module. This module executes the scheduling instructions of the dynamic area control center to complete tasks such as vehicle entry and exit, empty package loading, and empty package return. The specific operation flow is as follows:
[0068] The return route consists of n lines, denoted as b1, b2, ..., b n n≥1, and each incoming railway line includes j1, j2, ..., j nEach empty space, j1, j2, ..., j n All values are ≥1; The empty package return function module numbers the vehicles entering the empty package return function area, sorts them according to task importance based on the current task information of the vehicles, and marks parameters such as the entry time, number of uses, and parking location of the vehicles to complete the management of the vehicles; it numbers the empty packages entering the empty package return function area, sorts them according to information such as return location and waiting time to complete the management of the empty packages; it manages each return route according to the status of the vehicles, return locations, and empty package task completion, updates the return route status information, receives adjustment scheme information from the dynamic adjustment module, switches the return route function in the area according to instructions, updates the scope of the empty package return function area, and completes the management of the return routes; it issues instructions containing information such as return routes, vehicles, and empty package return locations to complete the scheduling execution task.
[0069] The repacket caching module of the dynamic area control center is responsible for recording, analyzing and managing the data within the repacket caching function area, including information such as cache location and quantity, repacket location, and repacket quantity, and maintains information interaction with the real-time information tracking module; this module executes the scheduling instructions of the dynamic area control center to complete tasks such as repacket loading and repacket transportation.
[0070] The empty package caching module of the dynamic area control center is responsible for recording, analyzing and managing the data within the empty package caching function area, including information such as caching location and quantity, empty package location, and empty package quantity, and maintains information interaction with the real-time information tracking module; this module executes the scheduling instructions of the dynamic area control center to complete tasks such as empty package loading and empty package dispatch.
[0071] It should be noted that the connection between the areas managed by the loaded package entry module and the empty package return module can be achieved through rail transport (i.e., the iron package is pulled by a transport vehicle and the area is switched via a switch), or by other transport methods such as locomotives, rolling stock, electric flatcars, trucks, and overhead cranes; the total number of lines managed by the loaded package entry module and the empty package return module is ≥2, and the number of empty slots that can accommodate iron packages on each line is ≥1; the loaded package buffer area is located within the steel-iron interface area, in the connecting area before the loaded package enters the loaded package entry area; the empty package buffer area is located within the steel-iron interface area, in the connecting area before the empty package enters the empty package return area from the steel area.
[0072] This invention also provides a method for dynamic control of ladles applied in the steel-iron interface region, implemented through the above-mentioned system, comprising the following steps:
[0073] Heavy load start-up:
[0074] The dynamic area control center acquires and analyzes information from each module of the system. After receiving the steel production plan and iron arrival information from the iron zone, it initiates the iron arrival task based on the iron usage time of the steel zone, whether the iron arrival function area and the iron buffer function area of the heavy package are ready to receive the iron, and directs the heavy packages outside the iron-steel interface area to enter the iron-steel interface area.
[0075] Railway route scheduling:
[0076] The dynamic area control center performs conditional judgments and completes the loading route scheduling based on the information from the heavy package loading function module and the number of heavy packages entering the loading area. The conditional judgment rule is to compare the available loading positions in the heavy package loading function area with the number of heavy packages entering the steel-iron interface area to determine the storage location and entry route of the heavy packages. If the available loading positions in the heavy package loading function area are greater than or equal to the number of heavy packages entering the steel-iron interface area, the heavy packages are driven directly into their positions, and the transport vehicle waits for new scheduling instructions. If the available loading positions in the heavy package loading function area are less than the number of heavy packages entering the steel-iron interface area, some heavy packages are driven into available loading positions, and the remaining heavy packages without loading positions are transported by the transport vehicle to the heavy package buffer function area for temporary storage and to wait for instructions. When the available loading positions in the heavy package loading function area become available again, the heavy package loading function module sends a signal to the dynamic area control center, and the dynamic area control center schedules the transport vehicle to move the heavy packages from the heavy package buffer function area to the heavy package loading function area.
[0077] Heavy package hoisting operation:
[0078] Once a heavy package arrives at its target location in the loading area, the loading module sorts it according to information such as arrival time, route, specific location on the same route, and whether the route corresponds to the steel mill's process, determining the priority order for supplying heavy packages to the steel zone. The steel zone information module immediately transmits the heavy package information from the loading area to the steel zone, which then allocates transportation vehicles to carry out the transport task. If the steel zone is unable to receive the heavy package at this time, the package continues to wait.
[0079] Re-lifting of heavy packages:
[0080] Once the heavy package is lifted by the transport vehicle and removed from the heavy package loading area, the real-time information tracking module immediately updates the vacancy information and synchronizes it to the dynamic area control center.
[0081] Empty packet return scheduling:
[0082] The steel area information module continuously acquires information such as the status of the steel ladle, process progress, and completion of iron exchange in the steel area, and transmits it to the dynamic area control center in real time.
[0083] When the empty package return function area is ready to receive, the steel area information module immediately transmits the information to the steel area, and the steel area dispatcher directs the transportation vehicle to transport the empty package to the empty package return function area.
[0084] When the empty package return position in the empty package return function area is not ready to receive, the steel area information module immediately transmits the information from the empty package buffer function module to the steel area. The steel area dispatcher then directs the transport vehicles to temporarily store the empty packages in the empty package buffer function area. When the empty package return position in the empty package return function area is ready to receive, the empty package return function module sends a signal to the dynamic area control center. The dynamic area control center then dispatches the empty packages from the empty package buffer function area to the empty package return function area.
[0085] Empty package returned to the ironworks:
[0086] When an empty package in the empty package return function area completes its loading action and is ready to return to the railway area, the empty package return function module sends a signal to the dynamic area control center. The dynamic area control center immediately initiates the empty package return task and directs the transport vehicle to carry the empty package back to the railway area. At the same time, the railway area information module sends empty package information, transport vehicle information, etc. to the railway area.
[0087] It should be noted that during the entire ladle operation, the dynamic area control center maintains real-time information exchange with the iron zone and steel zone, and adjusts its own process rhythm according to the real-time information exchange; the dynamic area control center submits production rhythm adjustment requests to the iron zone through the iron zone information module based on the steel zone module information, the heavy ladle feeding function module information, and the empty ladle return function module information; the dynamic area control center submits production rhythm adjustment requests to the steel zone through the steel zone information module based on the iron zone module information and the information of each function module.
[0088] Throughout the entire ladle transfer process, the dynamic area control center continuously interacts with the dynamic adjustment module, and integrates information from various functional area modules, iron zone production rhythm information, and steel zone production rhythm information to perform real-time dynamic matching and adjustment of the regional lines.
[0089] The dynamic adjustment module's regional control dynamic adjustment logic is as follows: Figure 2 As shown. During dynamic matching and adjustment, initially, functional lines are activated sequentially according to the demand for iron bags, and their functional attributes are defined. Lines are then allocated based on these attributes. As the number of iron bags increases, lines in the heavy baggage entry functional area and the empty baggage return functional area are gradually added and activated. The heavy baggage entry functional area and the empty baggage return functional area manage each line based on the line activation time, the location of the transport vehicle, the completion status of heavy baggage (or empty baggage) tasks, and the number and location of empty heavy baggage (empty baggage) slots.
[0090] The dynamic adjustment module acquires information in real time from the dynamic area control center, the real-time information tracking module, the iron zone information module, and the steel zone information module, and performs data analysis.
[0091] After completing the current node task (i.e., the task of repacking into the railway or the task of returning empty packages), each functional line triggers the dynamic adjustment module to adjust its functions.
[0092] The dynamic adjustment module analyzes various factors such as the production rhythm of the ironworks and steelworks, the number and location of heavy-loaded packages in the heavy-load loading area, the number and location of empty-loaded packages returning to the empty-load return area, the load status of all functional lines, the operating rate of transport vehicles, and the utilization rate of turnouts. After analyzing and deriving a new adjustment plan, it immediately transmits it to the dynamic area control center to execute real-time switching of line functions and real-time allocation of transport vehicles. After a functional line completes the function switch or maintains its function, it is re-added to the line queue of the corresponding functional area. The dynamic conversion logic diagram of functional lines is as follows: Figure 5 As shown.
[0093] The ladle dynamic control system and method of the present invention are applied to the operation and control of ladles in the steel interface area. For multi-line scenarios, it can achieve more precise dynamic control of logistics at the steel interface. The ladle dynamic control system and method of the present invention effectively ensure the continuity of the entire production process, help improve production efficiency, reduce ladle waiting time, and significantly reduce transportation congestion.

[0107] Example 2
[0108] This embodiment uses the ladle dynamic control system of Embodiment 1 to dynamically control the ladle in the steel interface area.
[0109] The iron-steel interface area layout diagram of this embodiment is as follows: Figure 3 The diagram shows the iron-steel interface area of a large steel plant in China. It includes a heavy ladle buffer area, a heavy ladle molten iron inlet area, an empty ladle return area, and an empty ladle buffer area. Heavy ladles refer to ladles transporting molten iron from the iron processing zone to the iron-steel interface area, while empty ladles refer to ladles returning after being added to the converter. The heavy ladle buffer area is located at the connection point before the ladle is transported from the iron processing zone to the iron-steel interface area, and the empty ladle buffer area is located at the connection point after the ladle is added to the converter and returns to the iron-steel interface area. There are four locomotive transport tracks (i.e., molten iron inlet lines and / or empty ladle return lines), each serving both molten iron inlet and empty ladle return functions. These are designated as functional track a, functional track b, functional track c, and functional track d. Each track has three molten iron inlet positions and / or three empty ladle return positions. The transport vehicles are locomotives, frames, and overhead cranes. The locomotives use the transport tracks to transport heavy ladles to the steel plant or return empty ladles to the iron processing zone. The steel plant is equipped with desulfurization equipment and converters. The overhead cranes lift heavy packages from the rails to the desulfurization equipment and converters.
[0110] The flowchart of the method for dynamic management and control of iron ladles is as follows: Figure 4 As shown, it includes:
[0111] Heavy load start-up:
[0112] The dynamic area control center acquires and analyzes information from each module of the system. After receiving the steel production plan and iron arrival information from the iron zone, it initiates the iron arrival task based on the iron usage time of the steel zone, whether the iron arrival function area and the iron buffer function area of the heavy package are ready to receive the iron, and directs the heavy packages outside the iron-steel interface area to enter the iron-steel interface area.
[0113] Railway route scheduling:
[0114] The dynamic area control center makes conditional judgments and completes the iron-in-railway scheduling based on the information of the heavy package iron-in-railway function module and the number of heavy packages entering the iron-steel interface area. The conditional judgment rule is to compare the empty iron-in-railway positions in the heavy package iron-in-railway function area with the number of heavy packages entering the iron-steel interface area to obtain the storage location and entry route of the heavy packages.
[0115] If the number of empty iron-feeding positions in the heavy package iron-feeding functional area is greater than or equal to the number of heavy packages entering the iron-steel interface area, the heavy packages will drive directly into their positions and the transport vehicle will wait for new dispatch instructions.
[0116] If the number of empty loading positions in the heavy package loading area is less than the number of heavy packages entering the steel-iron interface area, some heavy packages will enter empty loading positions. The remaining heavy packages without loading positions will be transported by transport vehicles to the heavy package buffer area for temporary storage and to await instructions. When the empty loading positions in the heavy package loading area become available again, the heavy package loading module will send a signal to the dynamic area control center. The dynamic area control center will then dispatch transport vehicles to move the heavy packages from the heavy package buffer area to the heavy package loading area.
[0117] Heavy package hoisting operation:
[0118] Once a heavy package arrives at its target location in the loading area, the loading module sorts the packages based on their arrival time, the route they are on, their specific location on the same route, and whether the route corresponds to the steel mill's process, thus determining the priority order for the steel yard to supply the heavy packages. The steel yard information module immediately transmits the heavy package information from the loading area to the steel yard, which then allocates transportation vehicles to carry out the transport task. If the steel yard is unable to receive the heavy package at this time, the package continues to wait.
[0119] Re-lifting of heavy packages:
[0120] Once the heavy package is lifted by the transport vehicle and removed from the heavy package loading area, the real-time information tracking module immediately updates the vacancy information and synchronizes it to the dynamic area control center.
[0121] Empty packet return scheduling:
[0122] The steel area information module continuously acquires information such as the status of the steel ladle, process progress, and completion of iron exchange in the steel area, and transmits it to the dynamic area control center in real time.
[0123] When the empty package return function area is ready to receive, the steel area information module immediately transmits the information to the steel area, and the steel area dispatcher directs the transportation vehicle to transport the empty package to the empty package return function area.
[0124] When the empty package return position in the empty package return function area is not ready to receive, the steel area information module immediately transmits the information from the empty package buffer function module to the steel area. The steel area dispatcher then directs the transport vehicle to deliver the empty package to the temporary storage area of the empty package buffer function area. When the empty package return position in the empty package return function area is ready to receive, the empty package return function module sends a signal to the dynamic area control center. The dynamic area control center then dispatches the empty package from the empty package buffer function area to the empty package return function area.
[0125] Empty package returned to the ironworks:
[0126] When an empty package in the empty package return function area completes its loading action and is ready to return to the railway area, the empty package return function module sends a signal to the dynamic area control center. The dynamic area control center immediately initiates the empty package return task and directs the transport vehicle to carry the empty package back to the railway area. At the same time, the railway area information module sends empty package information, transport vehicle information, etc. to the railway area.
[0127] It should be noted that during the entire ladle operation, the dynamic area control center maintains real-time information exchange with the iron zone and steel zone, and adjusts its own process rhythm according to the real-time information exchange; the dynamic area control center submits production rhythm adjustment requests to the iron zone through the iron zone information module based on the steel zone module information, the heavy ladle feeding function module information, and the empty ladle return function module information; the dynamic area control center submits production rhythm adjustment requests to the steel zone through the steel zone information module based on the iron zone module information and the information of each function module.
[0128] Throughout the entire ladle transfer process, the dynamic area control center continuously interacts with the dynamic adjustment module, and integrates information from various functional area modules, iron zone production rhythm information, and steel zone production rhythm information to perform real-time dynamic matching and adjustment of the regional lines.
[0129] The dynamic adjustment module's regional control dynamic adjustment logic is as follows: Figure 2 As shown. During dynamic matching and adjustment, initially, functional lines are activated sequentially according to the demand for iron bags, and their functional attributes are defined. Lines are then allocated based on these attributes. As the number of iron bags increases, lines in the heavy baggage entry functional area and the empty baggage return functional area are gradually added and activated. The heavy baggage entry functional area and the empty baggage return functional area manage each line based on the line activation time, the location of the transport vehicle, the completion status of heavy baggage (or empty baggage) tasks, and the number and location of empty heavy baggage (empty baggage) slots.
[0130] The dynamic adjustment module acquires information in real time from the dynamic area control center, the real-time information tracking module, the iron zone information module, and the steel zone information module, and performs data analysis.
[0131] After completing the current node task (i.e., the task of repacking into the railway or the task of returning empty packages), each functional line triggers the dynamic adjustment module to adjust its functions.
[0132] The dynamic adjustment module analyzes various factors such as the production rhythm of the ironworks and steelworks, the number and location of heavy packages entering the ironworks functional area, the number and location of empty packages returning to the empty package functional area, the load status of all functional lines, the operating rate of transport vehicles, and the utilization rate of turnouts. After analyzing and deriving a new adjustment plan, it immediately transmits it to the dynamic area control center to execute the real-time switching of line functions and to allocate transport vehicles in real time. After the functional line completes the function switching or maintains its function, it is rejoined to the line queue of the corresponding functional area.
[0133] In this embodiment, the average waiting time for iron bags is reduced by 10 minutes, and the congestion of transportation vehicles is significantly reduced.
[0134] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
