[0022] The Smart Hot Metal Transportation System aims to improve production scheduling automation and optimize scheduling organizational structure. It integrates and interconnects driving command, vehicle monitoring, video surveillance, iron and steelmaking management systems, and ladle management systems. It organically integrates operating methods, interface displays, and processing procedures to establish a unified platform, forming a complete operation management, monitoring, and scheduling command system to achieve intelligent and modern hot metal transportation. The Smart Hot Metal Transportation System is a highly integrated and intelligent production management system designed to optimize the transportation process of hot metal from blast furnaces to steelmaking or rolling mills, improve production efficiency, reduce operating costs, and enhance production safety. Figure 1 As shown in the figure, the intelligent molten iron transportation system includes an intelligent molten iron dispatching system and an intelligent molten iron autonomous driving system. The intelligent molten iron dispatching system communicates with the blast furnace / steelmaking system through a designated communication protocol and data interface, effectively connecting the intelligent blast furnace and steelmaking systems. The intelligent molten iron dispatching system obtains production process information, such as steelmaking production plans and equipment status, from the steelmaking Production Execution System (PES), and obtains blast furnace raw material composition, furnace conditions, and temperatures from the pre-iron manufacturing execution system (MES). This information drives the operation of various models in the intelligent molten iron transportation system. The intelligent molten iron dispatching system is coupled with the ladle control subsystem and the intelligent molten iron car monitoring subsystem to form a ground-based intelligent molten iron transportation control system.

[0023] The ladle-process control subsystem, upon receiving blast furnace tapping, steelmaking, or rolling mill plans, generates ladle scheduling instructions based on the available ladle resource status and transmits them to the intelligent hot metal car monitoring subsystem. It also generates and transmits hot metal car scheduling instructions based on the current hot metal car usage and line resource status. This subsystem, centered around the ladle, tracks information on the same ladle throughout multiple stages, including blast furnace tapping, hot metal transportation, hot metal desulfurization, and converter iron addition. It also establishes dynamic hot metal balance decision-making to match ladles with production tasks. Specifically, this subsystem serves as the brain of the entire intelligent hot metal transportation system, receiving production plan information from the blast furnace, steelmaking, or rolling mill, including tapping, steelmaking, and steelmaking plans. Based on these plans, combined with the current status of ladle resources (such as the number of ladles, their location, and whether they are empty), the status of hot metal cars (such as their location, load, and whether they are idle), and the status of track resources (such as track occupancy and maintenance schedules), ladle and car scheduling instructions are automatically generated. These instructions are then transmitted to the intelligent hot metal car monitoring subsystem. This enables intelligent scheduling of ladles and cars, reduces manual intervention, improves scheduling efficiency and accuracy, and ensures the continuity and stability of hot metal transportation.

[0024] In the smart molten iron transportation system, upon receiving a blast furnace tapping schedule, steelmaking schedule, or rolling mill schedule, the ladle control subsystem generates corresponding scheduling instructions based on the current resource status and transmits them to the intelligent molten iron car monitoring subsystem to ensure efficient and smooth molten iron transportation. The following details the generation process of ladle and car scheduling instructions.

[0025] The ladle-wide control subsystem first receives the blast furnace tapping plan, steelmaking plan, or steel rolling plan. These plans contain key information such as the molten iron production volume, transportation destination, and time requirements. Through the ladle status monitoring module in the ladle-wide control subsystem, the system obtains the status of existing ladle resources in real time, including the available quantity, location, and current status of the ladle (such as whether it is filled with molten iron, molten iron temperature, weight, etc.). Based on the received plan information and the ladle resource status, the system performs intelligent matching to determine which ladles are suitable for executing the current tapping, steelmaking, or steel rolling plan. Combined with the current status and location of the ladle, as well as the urgency of the plan, transportation route, and other factors, a reasonable ladle scheduling strategy is formulated to ensure that the molten iron can be transported to the designated location on time, in quantity, and according to quality. The generation process of the ladle scheduling strategy is as follows: Real-time information is collected on the status of existing ladle resources, including their available quantity, location, and current status (e.g., whether they contain molten iron, their temperature, and weight). Based on this planned information, the system preliminarily screens available ladles that may meet the requirements. For example, based on the transport destination, ladles with shorter distances or smoother transport routes are selected; based on time constraints, ladles that can complete the transport task on time are selected. Combined with real-time data provided by the ladle status monitoring module, a comprehensive status assessment is performed on the initially screened ladles. Factors considered include whether the remaining capacity of the ladle meets the planned requirements, whether the molten iron temperature meets subsequent process requirements, and whether the ladle cover is in good condition. This assessment identifies the truly usable ladles and eliminates those with faults or poor condition, ensuring smooth transport. Based on the available ladles, the system further considers optimizing their location and transport routes. The system calculates factors such as the distance to the transport destination and the transport time for each ladle to select the most suitable ladle for the task. At the same time, the system plans the optimal transportation route based on the status of line resources, avoiding conflicts with other transportation tasks and improving transportation efficiency. The system assigns different priorities to projects of varying urgency. For example, an urgent steelmaking project may require prioritizing the transportation of hot metal ladles. When formulating scheduling strategies, the system adjusts the allocation of hot metal ladles based on the project's priority to ensure that urgent tasks are handled promptly.

[0026] Based on the dispatch strategy, the ladle-by-ladle control subsystem generates specific ladle dispatch instructions, including detailed information such as the ladle number, transportation destination, departure time, and estimated arrival time. These instructions are then transmitted to the intelligent ladle car monitoring subsystem, enabling real-time monitoring and dispatch of the ladle's transportation process.

[0027] The process of formulating the hot metal car scheduling strategy is as follows: After receiving ladle dispatch instructions, the system identifies the transport tasks and requirements for each ladle. Simultaneously, the intelligent ladle monitoring subsystem monitors the ladle's usage status, including vehicle availability, current location, and battery level. Preliminary vehicle matching is performed based on the ladle's transport task and ladle status. For example, for long-distance transport tasks, ladle trucks with sufficient battery life are prioritized; for time-sensitive transport tasks, idle ladle trucks closer to the departure point are selected. The system also considers track resource availability, such as track occupancy and switch status. It assesses the feasibility of different ladle routes to avoid track conflicts or switch failures. If a route is congested or experiencing a fault, the system promptly adjusts the transport route and selects alternative routes to ensure the ladle reaches its destination. Based on transport feasibility, ladle scheduling is optimized. The system comprehensively considers the interdependencies between multiple transport tasks to rationally arrange the ladle's travel order and task allocation. For example, multiple transport tasks in the same direction are arranged on the same molten iron car whenever possible, reducing the vehicle's idle mileage and improving transportation efficiency. When formulating a scheduling strategy, it is also necessary to consider possible special circumstances, such as molten iron car failures and sudden line failures. The system will develop contingency plans in advance and can quickly adjust the scheduling strategy when abnormal situations occur to ensure the continuity of molten iron transportation. For example, when a molten iron car breaks down, the system will promptly arrange for another idle molten iron car to take over the task and notify maintenance personnel of the faulty car information for processing. Based on the scheduling strategy, the system generates specific molten iron car scheduling instructions, including detailed information such as the molten iron car number, transport task, departure time, route, and estimated arrival time. The generated molten iron car scheduling instructions are transmitted to the intelligent molten iron car monitoring subsystem, which monitors and schedules the molten iron car's driving process in real time to ensure the smooth completion of the transportation task.

[0028] The intelligent molten iron car monitoring subsystem is connected to the ladle-process control subsystem and is configured to generate a transport route instruction containing a transport path based on the received ladle and car scheduling instructions. This instruction is then transmitted to the intelligent molten iron autonomous driving system. Serving as a bridge between the ladle-process control subsystem and the intelligent molten iron autonomous driving system, this subsystem is responsible for receiving and interpreting scheduling instructions from the ladle-process control subsystem. Combining real-time map data and vehicle status information, this subsystem generates a transport route instruction containing a transport path. These instructions are then transmitted to the intelligent molten iron autonomous driving system, guiding the molten iron car along the planned route. Intelligent route planning reduces molten iron car idle time and energy consumption, improving transport efficiency. Furthermore, real-time monitoring of the molten iron car's location and status provides data support for emergency response. A car-ladle matching model is constructed to allocate tasks between the molten iron car and the ladle; task-based molten iron car route planning is established; and dynamic feedback between efficient scheduling and autonomous driving is established to ensure efficient and conflict-free route scheduling.

[0029] The process of building the above vehicle-package matching model is as follows: ① Clarify matching objectives: The core goal of car-ladle matching is to ensure efficient and safe completion of molten iron transportation tasks, while optimizing resource utilization and reducing transportation costs. Specifically, it is necessary to minimize the idle mileage of molten iron cars, shorten the waiting time of molten iron ladles during transportation, and ensure that molten iron arrives at its destination within the specified time to meet production needs.

[0030] ② Identify matching elements, which include molten iron car elements and ladle elements. Molten iron car elements include the car's capacity (maximum molten iron capacity), battery level (for electric molten iron cars), current location, driving speed, and fault status. For example, a molten iron car has an 80-ton capacity, 80% remaining battery level, is located near a blast furnace, and is traveling at a normal speed with no faults. Ladle elements include the ladle's number, current molten iron level, temperature, destination, and estimated iron receiving or pouring time. For example, a ladle with the ladle number 001, a current molten iron level of 60 tons, a temperature of 1450°C, a destination of the steelmaking workshop, and an estimated iron receiving completion time of 10:00.

[0031] ③ Establish matching rules, including capacity matching rules, distance matching rules, time matching rules, and power matching rules. The capacity matching rule requires that the capacity of the hot metal car must be greater than or equal to the current amount of hot metal in the ladle to ensure that the car can safely carry the ladle. For example, if the ladle holds 70 tons of hot metal, only hot metal cars with a capacity greater than or equal to 70 tons can be assigned to it. The distance matching rule prioritizes assigning idle hot metal cars that are closer to the ladle's current location to reduce the car's travel distance and time. For example, the distance between the hot metal car and the ladle can be calculated using a GPS positioning system, and the car closest to the ladle can be selected. The time matching rule considers the ladle's estimated iron receiving or unloading time, as well as the car's arrival time at the destination, to ensure that the hot metal can be transported within the specified time. For example, if the ladle is expected to complete receiving iron at 11:00 and must arrive at the steelmaking workshop by 11:30, the assigned hot metal car should arrive before 11:30. The power matching rule is that the remaining power of the molten iron car must be sufficient to complete the transport mission and return to the charging station. For example, if the transport mission is expected to consume 30% of the power and the return to the charging station requires 20% of the power, the remaining power of the molten iron car must be at least 50% to complete the mission.

[0032] ④Construct mathematical model: The car-package matching model can be constructed by using mathematical methods such as linear programming and integer programming. Taking linear programming as an example, let x ij is a decision variable. When hot metal car i is assigned to hot metal ladle j, x ij =1; otherwise, x ij = 0. The objective function can be set to minimize the total transportation cost (including travel distance cost, time cost, etc.), and the constraints include the above-mentioned capacity, distance, time and power matching rules.

[0033] The above-mentioned car-package matching process is: collecting relevant information of the molten iron car and molten iron ladle from each subsystem, such as the capacity, power, location, molten iron volume, temperature, destination and other data mentioned above.

[0034] Based on the complexity of the vehicle-package matching model and actual needs, select an appropriate matching algorithm. Examples include greedy algorithms, genetic algorithms, and ant colony algorithms. Taking the greedy algorithm as an example, its basic idea is to select the optimal matching solution at each step. The specific steps are as follows: ① Initialization: Enter the information of all molten iron cars and ladles into the system and initialize the decision variable x ij =0.

[0035] ② Traverse the molten iron ladle: For each molten iron ladle, select the closest molten iron car from all idle molten iron cars according to the distance matching rule.

[0036] ③ Check other rules: Check the capacity and power of the selected molten iron car to see if they meet the requirements of the molten iron ladle. If they do, then ij =1, and mark the molten iron car as non-idle; if not satisfied, continue to select the next molten iron car with a closer distance for inspection until a suitable molten iron car is found or all molten iron cars are traversed.

[0037] ④ Repeat: Repeat the above steps until all ladles are matched or there is no suitable molten iron car available for allocation.

[0038] ⑤ Result Evaluation: Evaluate the generated matching results based on the matching objectives. Evaluation metrics may include total transport distance, total transport time, and molten iron car utilization. For example, the sum of the travel distances of all molten iron cars can be calculated. If this value is large, it indicates that the matching results may not be optimal. If the evaluation results are not ideal, an optimization algorithm can be used to adjust the matching results. For example, a genetic algorithm can be used to optimize the initial matching solution, generate new matching solutions through operations such as crossover and mutation, and select the more optimal solution as the final result.

[0039] ⑥ Based on the final matching results, task assignment instructions are generated for the hot metal car and ladle. The instructions should include information such as the hot metal car number, ladle number, transportation route, and departure time. The generated instructions are transmitted to the intelligent hot metal car monitoring subsystem and relevant operators via the communication interface to ensure that the hot metal car executes the transportation task according to the instructions.

[0040] The following details the process of generating transport route instructions: First, the intelligent hot metal car monitoring subsystem receives ladle and car dispatch instructions from the dispatch module. The ladle dispatch instruction specifies the ladle's transportation destination, time requirements, and other information; the car dispatch instruction determines the hot metal car that will carry out the transportation task.

[0041] Secondly, by communicating with ground equipment (such as track circuits, signal machines, and switch control systems) and the intelligent molten iron car monitoring subsystem, real-time line resource status (including track occupancy, switch status, whether there are obstacles, etc.) and the current position and status of the molten iron car (such as power level, whether there is a fault, etc.) are obtained.

[0042] Next, based on the ladle's destination and the status of track resources, several feasible transport routes are initially screened. For example, if a track is under maintenance, routes that pass through that track are excluded. The preselected routes are further optimized based on the ladle's current location and status. For example, the route closest to the ladle's current location and with the lowest power consumption is selected to ensure smooth arrival. During route planning, changes in track status are monitored in real time. If new obstacles or changes in track status are detected, the route plan is adjusted promptly to ensure safe transport. Based on the time requirements in the ladle's dispatch instructions, time limits for key nodes are added to the transport route instructions, such as departure time, time to pass a specific switch, and time to reach the destination. Integrating the ladle's autonomous driving capabilities with the control requirements of ground equipment, the instructions clearly specify the ladle's operational requirements for different sections of the route, such as travel speed and steering at switches. The planned transport routes, time points, and operational requirements are integrated into a detailed transport route instruction document. The generated instruction document is verified to ensure accuracy and completeness. Verification includes ensuring the route is feasible, ensuring the timeframe is reasonable, and ensuring that the operational requirements meet system specifications. Verified transport route instructions are then transmitted to the intelligent molten iron automated driving system via a pre-established communication interface. Upon receiving the instructions, the intelligent molten iron automated driving system sends a confirmation message to the dispatching system. If any anomalies occur during transmission, the system promptly provides error feedback, allowing the dispatching system to regenerate and retransmit the instructions.

[0043] The intelligent molten iron automatic driving system, connected to the intelligent molten iron car monitoring subsystem, is configured to control the molten iron car to arrive at the designated taphole to begin receiving iron according to the transport route instructions. After receiving iron, the system controls the molten iron car to transport the ladle to the steelmaking or steel rolling ladle storage area. The system also provides feedback on the molten iron car's real-time position and status to the intelligent molten iron car monitoring subsystem. Specifically, this subsystem serves as the execution layer of the intelligent molten iron transportation system. It is responsible for controlling the molten iron car to automatically travel to the designated taphole to receive iron according to the transport route instructions transmitted by the intelligent molten iron car monitoring subsystem. After receiving iron, the system automatically controls the molten iron car to transport the ladle to the steelmaking or steel rolling ladle storage area. Furthermore, the system provides real-time feedback, transmitting the molten iron car's real-time position and status information back to the intelligent molten iron car monitoring subsystem for real-time monitoring and adjustment. This enables automated molten iron car operation, reducing the risks and costs of manual operation and improving transportation safety and efficiency. Furthermore, this real-time feedback mechanism enables the system to quickly respond to abnormal situations, ensuring smooth production processes.

[0044] The intelligent molten iron transportation system provided by the present invention integrates multiple subsystems to realize the automation and intelligent scheduling of the molten iron transportation process, improve production efficiency, reduce operating costs, enhance production safety, and promote intelligent coordination of steelmaking, ironmaking and transportation.

[0045] The ladle-process control subsystem receives blast furnace tapping, steelmaking, or rolling plans and performs a comprehensive analysis based on the current ladle resource status, hot metal car usage, and line resource status. This information integration capability enables the system to make more scientific and rational scheduling decisions, avoiding scheduling errors that can occur with traditional methods due to incomplete or delayed information. Based on this information analysis, the ladle-process control subsystem automatically generates ladle and hot metal car scheduling instructions and transmits them to the intelligent hot metal car monitoring subsystem. This automated scheduling reduces manual intervention and improves scheduling efficiency and accuracy.

[0046] Based on the ladle and car scheduling instructions received, the intelligent molten iron car monitoring subsystem generates a transport routing instruction containing a specific transport route and transmits it to the intelligent molten iron automated driving system. This path planning capability ensures that the molten iron car follows the optimal route, improving transportation efficiency. The intelligent molten iron car monitoring subsystem also receives real-time location and status information from the intelligent molten iron automated driving system, providing data support for subsequent scheduling decisions. This real-time monitoring and feedback mechanism enables the system to promptly adjust scheduling strategies to respond to unexpected situations.

[0047] Based on received transport route instructions, the intelligent molten iron autonomous driving system controls the molten iron car to automatically drive to the designated taphole to begin receiving iron. Once receiving iron, it automatically transports the ladle to the steelmaking or steel rolling ladle storage area. This autonomous driving capability reduces the risk of manual operation and improves transportation safety and stability. The intelligent molten iron autonomous driving system also reports the molten iron car's real-time location and status to the intelligent molten iron car monitoring subsystem, enabling visual monitoring of the entire transportation process.

[0048] Through the collaborative work of these three subsystems, the intelligent hot metal transportation system achieves the following improvements in informationization and intelligence: By integrating blast furnace tapping plans, steelmaking plans, steel rolling plans, and resource status information such as ladles, hot metal cars, and lines, the system achieves comprehensive information transparency, providing strong support for scheduling decisions. The system automatically generates scheduling instructions and route planning, reducing manual intervention and improving scheduling efficiency and accuracy. Through autonomous driving technology and real-time monitoring and feedback mechanisms, the system enables intelligent transportation of hot metal cars, improving transportation safety and stability.

[0049] In some embodiments, the intelligent molten iron transportation system not only includes the ladle full-process control subsystem, the intelligent molten iron dispatching system, and the intelligent molten iron automatic driving system, but also includes the following subsystems: Figure 1 As shown, the intelligent molten iron transportation system also includes: Ground equipment is the infrastructure part of the smart molten iron transportation system. Through automation and intelligent means, ground equipment provides efficient, safe and reliable support for molten iron transportation, and promotes the intelligent management and scheduling of the entire system.

[0050] The ground equipment is connected to the intelligent molten iron automatic driving system and the intelligent molten iron car monitoring subsystem respectively, and is used to receive equipment control instructions sent by the intelligent molten iron automatic driving system, and perform switch control, positioning assistance and charging operations during the intelligent molten iron automatic driving system performs the transportation task, and feeds back the execution results to the intelligent molten iron automatic driving system; after the molten iron car completes the transportation task, it provides automatic charging service and synchronizes the charging status to the intelligent molten iron car monitoring subsystem; and receives equipment scheduling instructions issued by the intelligent molten iron car monitoring subsystem, reports equipment operating status and fault information in real time, and adjusts equipment operating parameters according to the equipment scheduling instructions.

[0051] Specifically, while the intelligent molten iron autonomous driving system is performing its transport mission, ground equipment is responsible for receiving and executing switch control commands. Automatic or remote control of switch movement ensures the molten iron car can smoothly follow the planned route. The ground equipment is equipped with a switch control module, which communicates with the intelligent molten iron autonomous driving system, receives switch control commands, and activates the switch actuator to operate. The switch control module also provides status feedback, providing feedback to the intelligent system on the current status of the switch (e.g., whether it is fully engaged, faulty, etc.).

[0052] During the molten iron car's journey, ground-based equipment provides positioning assistance, helping the intelligent molten iron autopilot system achieve high-precision positioning and tracking. This equipment can include positioning sensors and signal transmitters, which communicate with the car's positioning receiver to provide precise location information. By leveraging multi-sensor fusion technology, ground-based equipment can further improve positioning accuracy and reliability.

[0053] After the molten iron car completes its transport mission, ground equipment provides automatic charging services, ensuring it can replenish its battery in time for its next transport mission. The ground equipment is equipped with charging stations and a charging management system. The charging stations connect to the charging ports on the molten iron car for automatic charging. The charging management system monitors the charging process to ensure safe and efficient charging. Furthermore, the charging management system synchronizes charging status with the intelligent molten iron car monitoring subsystem, facilitating monitoring and scheduling by management personnel.

[0054] After performing tasks such as switch control, positioning assistance, and charging, the ground equipment provides feedback to the intelligent molten iron autonomous driving system. This allows the system to promptly monitor the progress of the tasks and make appropriate adjustments and optimizations. The ground equipment transmits the results back to the intelligent molten iron autonomous driving system in the form of data or signals via a communication module. The intelligent molten iron autonomous driving system then processes and analyzes the received data to make decisions and provide instructions for the next step.

[0055] The ground equipment receives equipment scheduling commands from the intelligent molten iron car monitoring subsystem, reports equipment operating status and fault information in real time, and adjusts equipment operating parameters based on these commands. The ground equipment is equipped with a status monitoring module and a communication module. The status monitoring module monitors equipment operating status (such as temperature, pressure, and current) and fault information in real time, and transmits this data back to the intelligent molten iron car monitoring subsystem via the communication module. Furthermore, the ground equipment receives equipment scheduling commands from the intelligent molten iron car monitoring subsystem and adjusts equipment operating parameters (such as charging current and time) accordingly to ensure optimal equipment operation.

[0056] Through automated switch control and positioning assistance services, the present invention enables ground equipment to ensure that molten iron cars travel smoothly along the predetermined route, reducing waiting time and human intervention, and improving transportation efficiency.

[0057] In some embodiments, the ground equipment includes an interlocking system, charging facilities, etc. These devices work closely with the intelligent molten iron automatic driving system and the intelligent molten iron car monitoring subsystem to ensure the efficient, safe and automated transportation of molten iron.

[0058] The interlocking system (LCS) is a key part of the ground equipment of the intelligent molten iron transportation system. It is used to automatically switch the switch and open the route signal according to the molten iron car scheduling instructions, and send the open route signal to the intelligent molten iron automatic driving system. After receiving the open route signal, the intelligent molten iron automatic driving system controls the molten iron car to reach the designated iron outlet and generates the first arrival signal to be sent to the automatic covering control system.

[0059] Specifically, the interlocking system receives molten iron car dispatching instructions from the intelligent molten iron car monitoring subsystem and automatically or remotely switches the switches to implement crossing control, ensuring that the molten iron car follows the planned route. Once the switches are fully engaged, the interlocking system releases the route signal and transmits this signal to the intelligent molten iron automatic driving system. Through the communication module, the interlocking system accurately transmits the switch-in-position signal and route-open signal to the relevant systems, ensuring unimpeded information flow. Automated switch control and signal release reduce manual intervention, ensuring that the molten iron car reaches its designated location quickly and accurately.

It is used to communicate with the blast furnace foreman system through the intelligent molten iron scheduling system when receiving the first in-place signal to control the automatic opening and closing action of the molten iron ladle cover.

[0063] Specifically, the automatic ladle cover control system receives a first arrival signal from the intelligent molten iron automatic driving system, indicating that the molten iron car has accurately arrived at the designated taphole. Through the intelligent molten iron dispatching system, the automatic ladle cover control system communicates with the blast furnace foreman system to obtain the ladle cover opening and closing instructions. Based on the received instructions, the automatic ladle cover control system automatically controls the opening and closing of the molten iron ladle cover, ensuring safety and efficiency during molten iron transportation. Through automated ladle cover opening and closing control, the present invention reduces the risk of manual operation and improves the safety of the transportation process. Automated ladle cover opening and closing control reduces manual intervention time and improves the overall efficiency of molten iron transportation.

[0064] In the intelligent molten iron transportation system, ground equipment, as an important part of the entire system, provides infrastructure support and safety guarantee for molten iron transportation. Figure 1 As shown, the ground equipment also includes track circuits, crossing control systems, signals and switches.

[0065] The track circuit is a key component of ground equipment, used to detect whether a vehicle is on the track and its driving status. It senses the status of the track section through changes in the current loop and transmits this information to the intelligent molten iron autonomous driving system for scheduling and management.

[0066] Signals provide driving instructions to the molten iron car driver or the intelligent molten iron autonomous driving system, ensuring the vehicles safely follow their planned routes. Switches are critical track equipment, used to change the direction of travel. Interlocking systems automatically control switch operation according to the transportation plan, ensuring the correct and safe routing of the tracks.

[0067] The crossing control system is responsible for managing and controlling traffic safety at railway crossings. It works in conjunction with signals and switches to ensure the safety of molten iron vehicles passing through the crossings and prevent conflicts between vehicles and pedestrians.

[0068] Through the coordinated operation of track circuits, crossing controls, signals, and switches, the present invention provides a safe driving environment for molten iron vehicles, preventing accidents such as collisions and derailments. The ground equipment works closely with the intelligent molten iron dispatching system, providing accurate track and equipment status information for dispatchers, enabling the dispatching system to make reasonable dispatching decisions.

[0069] In some embodiments, the intelligent molten iron autonomous driving system is a key component of the intelligent molten iron transportation system. It utilizes highly automated technology to enable precise and efficient transportation of molten iron cars within the steel production process. The intelligent molten iron autonomous driving system integrates molten iron cars with an autonomous vehicle system. Through the collaborative operation of the autonomous vehicle system, supercapacitor molten iron cars, and an automatic parking system, the intelligent molten iron autonomous driving system achieves automated, efficient, safe, and intelligent molten iron transportation, improving both the efficiency and quality of molten iron transportation.

[0070] The molten iron car in the present invention is a supercapacitor molten iron car based on new energy. As a transportation vehicle, the supercapacitor molten iron car has the advantages of high efficiency, environmental protection, and energy saving. It uses supercapacitors as a power source and can be quickly charged to meet the high-intensity requirements of molten iron transportation. The supercapacitor molten iron car is equipped with a high-performance supercapacitor energy storage device that can be fully charged in a short time and provide continuous and stable power output. In addition, it also adopts a lightweight design and optimized structure, reducing energy consumption and improving transportation efficiency.

[0071] The autonomous driving vehicle system is the core of the intelligent molten iron autonomous driving system. Connected to the intelligent molten iron car monitoring subsystem, it receives and executes transport routing instructions from the intelligent molten iron car monitoring subsystem, controlling the molten iron car's movement accordingly. It precisely parks the molten iron car at the designated taphole, steelmaking, or steel rolling ladle parking area, ensuring accurate and timely molten iron transportation. The system integrates navigation, positioning, and control technologies, enabling real-time environmental awareness, autonomous planning of optimal driving routes, and accurate execution of parking commands. Furthermore, it features self-diagnosis and fault tolerance, ensuring stable operation in complex industrial environments.

[0072] The molten iron car includes an automatic parking system (i.e. Figure 1 The automatic parking system is an important component of the molten iron car and is connected to the autonomous driving on-board system. It is used to lock the molten iron car after it reaches the designated iron outlet and begins to receive iron, ensuring that it remains stable during the iron receiving process; after the iron receiving is completed, the molten iron car is released so that it can continue to perform its transportation task. Similarly, when the molten iron car reaches the steelmaking or steel rolling ladle parking area, the automatic parking system will also lock the molten iron car to prevent it from sliding or shifting. The automatic parking system uses sensors and actuators to monitor the status and position of the molten iron car in real time and automatically adjust the parking force as needed. At the same time, it also has a communication interface with the autonomous driving on-board system to ensure accurate information exchange between the two.

[0073] The intelligent molten iron automatic driving system of the present invention realizes the automation and efficiency of molten iron transportation through the coordinated work of the automatic driving vehicle system and the supercapacitor molten iron car. The system can autonomously plan the driving route and accurately execute the parking command, reducing manual intervention and waiting time, and improving transportation efficiency. The introduction of the automatic parking system ensures the stability of the molten iron car during the iron loading and parking process. The system can monitor the status and position of the molten iron car in real time, and automatically lock the molten iron car when necessary to prevent it from sliding or shifting, thereby enhancing the safety of the transportation process. The use of supercapacitor molten iron cars reduces the energy consumption and emissions of molten iron transportation. At the same time, since the system realizes automated transportation, it reduces labor costs and maintenance costs, further reducing operating costs. The application of the intelligent molten iron automatic driving system has improved the intelligence level of the entire steel production process. The system can exchange information and work in collaboration with other subsystems to realize intelligent scheduling and management of molten iron transportation, providing strong support for the digital transformation of steel enterprises.

[0074] In some embodiments, reference Figure 1 As shown, the intelligent molten iron automatic driving system also includes an autonomous perception system.

[0075] The autonomous perception system is a key subsystem within the intelligent molten iron automatic driving system. Connected to the automatic parking system, it senses the surroundings of the molten iron car in real time. When the molten iron car reaches the steelmaking or steel rolling ladle parking area, it sends a second arrival signal to the automatic parking system, causing it to lock the car. The system integrates multiple sensors, such as lidar, cameras, and millimeter-wave radar, which capture omnidirectional and multi-angle environmental data around the molten iron car. The autonomous perception system collects environmental data through sensors and processes and analyzes it in real time to identify obstacles, road conditions, and the movements of other vehicles and pedestrians around the molten iron car. Upon sensing the molten iron car's arrival at the steelmaking or steel rolling ladle parking area, the autonomous perception system sends a second arrival signal to the automatic parking system. This signal instructs the automatic parking system to lock the molten iron car, ensuring it is accurately parked in the designated location. To achieve more accurate environmental perception, the autonomous perception system utilizes sensor fusion technology, which integrates and analyzes data from multiple sensors to improve perception accuracy and reliability. The system's built-in data processing algorithms enable rapid processing and analysis of real-time environmental data, extracting useful information for decision-making. Data transmission between the autonomous perception system and the automated parking system is accomplished through a specific communication protocol, ensuring accurate and timely signals.

[0076] This invention leverages the real-time environmental perception capabilities of the autonomous sensing system, enabling the molten iron car to accurately identify obstacles and road conditions in complex and ever-changing industrial environments, allowing timely decisions such as avoidance or parking, greatly improving the safety of molten iron transportation.

By integrating multiple modules, this system enables real-time collection of ladle information, status monitoring, and generation of dispatch instructions, ensuring efficient and safe molten iron transportation. The ladle-by-ladle control subsystem includes a ladle automatic identification module, a ladle status monitoring module, and a ladle dispatch module.

[0078] The ladle automatic identification module collects ladle and vehicle numbers in real time and transmits them to the ladle status monitoring module. As the front-end sensing unit of the ladle control subsystem, the ladle automatic identification module is responsible for collecting ladle numbers and vehicle numbers in real time. This module utilizes technologies such as radio frequency identification (RFID), QR code scanning, or machine vision to ensure accurate and rapid identification of ladle numbers and vehicle numbers during ladle transportation. This identification information is immediately transmitted to the ladle status monitoring module.

[0079] The ladle status monitoring module, connected to the ladle automatic identification module, monitors key parameters of the corresponding ladle in real time, including molten iron temperature, weight, and ladle cover status, based on the ladle and car number information received. It then feeds this real-time status data back to the ladle scheduling module. If any anomalies are detected in this real-time status data, this abnormality information is forwarded to the intelligent ladle car monitoring subsystem. The ladle status monitoring module integrates multiple devices, including temperature sensors, weight sensors, and ladle cover status sensors. Through data acquisition and processing, it enables comprehensive, real-time monitoring of the ladle's status. Furthermore, the module provides data analysis and anomaly warning capabilities, enabling timely identification and resolution of potential safety hazards.

[0080] The ladle scheduling module is the decision-making center of the ladle control subsystem. It combines real-time status data to generate the current ladle resource status. Based on this status, it generates ladle scheduling instructions and transmits them to the intelligent hot metal car monitoring subsystem to guide the hot metal car's transportation tasks. The ladle scheduling module utilizes existing scheduling models to rationally allocate and schedule ladle resources. Furthermore, it considers multiple factors, including blast furnace tapping schedules, steelmaking or rolling mill tapping schedules, and line resource status, to ensure the scientific and rational nature of scheduling instructions.

[0081] The ladle-wide control and management subsystem of the present invention achieves dynamic management and optimized scheduling of ladle resources by collecting and monitoring ladle information in real time. This helps reduce the waiting time and idle time of the ladle and improves the overall efficiency of molten iron transportation. The status monitoring module can monitor key parameters such as the temperature, weight and ladle cover status of the ladle in real time, and promptly pushes the information to the intelligent molten iron car monitoring subsystem when an anomaly is found. This helps to promptly discover and address potential safety hazards, prevent accidents, and enhance the safety of molten iron transportation. By integrating multiple modules, the ladle-wide control and management subsystem achieves real-time collection of ladle information, status monitoring, and generation of scheduling instructions, laying the foundation for the comprehensive intelligence of future steel production processes. By optimizing the allocation and scheduling of ladle resources, the ladle-wide control and management subsystem helps reduce the operating costs of molten iron transportation. At the same time, due to the reduction of manual intervention and the improvement of transportation efficiency, operating costs are further reduced.

This interface provides data such as molten iron weight, volume, ladle information, tapping schedule, iron number information, and molten iron temperature, providing essential data for subsequent molten iron transportation. The 800-ton rail scale system provides molten iron weight information to the intelligent molten iron scheduling system through the external system interface; the liquid level gauge system provides molten iron volume information; the ladle tracking system provides ladle information; and the blast furnace foreman system provides tapping schedule information. This information is aggregated and sent to the intelligent molten iron scheduling system, which then generates ladle scheduling instructions.

[0084] The steelmaking / rolling-related external system interface connects to external systems for steelmaking / rolling, such as the 800-ton rail scale system, the converter secondary system, the ladle tracking system, and the rolling secondary system.

[0087] The intelligent molten iron car autonomous driving system controls the molten iron car according to transport route instructions, directing it to the designated taphole to begin receiving iron. After receiving iron, it then controls the molten iron car to transport the ladle to the steelmaking or steel rolling ladle storage area. The car's real-time position and status are fed back to the intelligent molten iron car monitoring subsystem. The intelligent molten iron car autonomous driving system integrates a supercapacitor molten iron car and an autonomous driving onboard system. The molten iron car is equipped with a locomotive capacitor and charging device, a PLC control system, a traction motor and inverter, an automatic ladle cover control system, an automatic parking system for the locomotive, and interface management. The autonomous driving onboard system includes an autonomous sensing system (such as speed sensors), a vehicle control system (VCS), a wireless communication system, precise positioning equipment, and interface management to ensure safe and stable operation of the molten iron car.

[0088] Ground equipment includes track circuits, LCS, crossing control, signals and switches, which provide basic support for the operation of molten iron cars and interact with the intelligent molten iron car automatic driving system to ensure the safety and smoothness of the transportation process.

[0089] The ironmaking MES provides the intelligent hot metal dispatching system with information such as tapping schedules, iron grades, and hot metal temperature. The steelmaking MES provides information such as steelmaking schedules, rolling schedules, and hot metal demand, which the intelligent hot metal dispatching system uses to coordinate transportation plans.

[0090] The interaction process of the above systems is as follows: ① The blast furnace related systems transmit information such as molten iron weight, molten iron capacity, ladle information, and iron tapping plan to the intelligent molten iron scheduling system through the external system interface.

[0091] ② The steelmaking / rolling related systems transmit vehicle gross weight, steelmaking plan, ladle tracking information, rolling plan and other information to the intelligent molten iron scheduling system through the external system interface.

[0092] ③ The ironmaking MES and steelmaking MES respectively provide the iron-making plan, iron number information, molten iron temperature information, as well as the steelmaking plan, steel rolling plan, molten iron demand information, etc. to the intelligent molten iron scheduling system.

Figure 3 As shown, the operation process is as follows: The ladle control subsystem within the intelligent hot metal dispatching system receives the tapping schedule from the blast furnace and the steel production plan from the steelmaking / rolling department. Based on the current ladle resource status, it dispatches empty ladles according to the hot metal balance. It then determines ladle-car matching based on line and vehicle availability, generates ladle scheduling instructions, and sends them to the intelligent hot metal car monitoring subsystem. The automated transportation system (ATS) within the intelligent hot metal car monitoring subsystem selects hot metal cars, routes, and ladle-car matching based on the current hot metal car usage and line resource status. It also selects routes based on the taphole and generates hot metal car scheduling instructions and specific transportation routes. The interlocking system then automatically switches the switches and opens the approach signals to ensure a safe operating environment.

[0116] After receiving the dispatching instruction, the molten iron car releases the automatic parking function and starts moving according to the movement authorization. In addition, the on-board autonomous perception system perceives the external environment and performs temporary parking and emergency treatment measures when encountering emergencies (such as foreign object intrusion).

[0117] After the molten iron car arrives at the blast furnace, the onboard autonomous driving system automatically and slowly parks it below the designated blast furnace taphole. Once the car is parked, the automatic parking system automatically locks. Subsequently, the car's PLC control system, using the intelligent molten iron scheduling system as an information intermediary, coordinates with the blast furnace foreman's system to automatically open and close the ladle cover. During the iron-receiving process, if the tapping schedule changes, the destination will be selected based on the temporary plan, and the molten iron car may reach a different taphole. After iron-receiving is completed, the automatic parking system releases, and the car moves toward the steelmaking / rolling direction. Using the onboard autonomous sensing system to assess the external environment, the car reaches the re-lagging parking line (a re-lagging destination is selected based on route and vehicle conditions). The car then automatically parks and diverts the empty ladle back to the blast furnace operating area. At this point, the car determines whether the ladle is unlinked from the car. If not, the next transport operation is performed based on production conditions. If unlinked, a single iron transport cycle within the ironmaking area is completed. The above operations are repeated repeatedly to complete the transportation of molten iron from the blast furnace to the steelmaking plant.
