Description

Technical Field

[0001] This invention relates to smart factories, specifically to a method and system for automatically covering and controlling the transport of molten iron in a factory area. Background Technology

[0002] In the intelligent rail transport system of the factory, molten iron transportation is an important business component. In the traditional molten iron transportation process, molten iron is mostly transported by open ladles and open torpedo cars, and the molten iron is transported by locomotive traction or top-loading of the torpedo cars.

[0003] The steel industry accounts for approximately 15% of the nation's total carbon emissions, making it the manufacturing sector with the highest carbon emissions. It is imperative for steel companies to implement carbon reduction targets. For every ton of steel, two tons of carbon are emitted, with blast furnace iron smelting generating the vast majority of these emissions. Besides improving blast furnace smelting processes, steel mills currently use open-top torpedo cars or ladles to transport molten iron. During the transport of molten iron from the blast furnace to steelmaking, the torpedo cars are open, resulting in continuous carbon emissions during transportation.

[0004] In order to achieve the goals of reducing temperature drop, saving energy and protecting the environment, it is necessary to design a capping device for the pouring opening to reduce carbon emissions and temperature drop of molten iron during transportation. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide an automatic capping control method and system for transporting molten iron in a factory area.

[0006] According to the present invention, an automatic capping control method for transporting molten iron in a factory area is provided, and the insulation cover of the torpedo ladle is controlled as follows:

[0007] For work-to-work station operations: after completing the work, cover the vehicle and drive away; open the cover before starting work at the next work station.

[0008] For the route from the work site to the parking point: after the work is completed, cover the vehicle and drive away; cover the parking point and keep it covered.

[0009] For the distance from the parking point to the work site: cover the parking point to keep it in place, and open the cover before starting work at the next work site;

[0010] For parking spot to parking spot: parking spots should be covered to maintain order.

[0011] Preferably, the location and access permissions for opening and closing the insulation cover are as follows:

[0012] For the control location of the vehicle itself, the control authority is either local control or remote control;

[0013] For control areas of automatic control systems, the control authority is either automatic control or manual control;

[0014] For the controlled areas of the work site, the control permissions are either remote control or manual control;

[0015] Only one control point can control the insulation cover at any given time. The control priority of the control points, from high to low, is: vehicle local > work point manual > control system manual > control system automatic. Among them, the work point manual control authority is only valid when the torpedo tanker is at the work point.

[0016] Preferably, the method includes the following steps:

[0017] First step: When the torpedo tanker is in automatic driving mode, the vehicle's location information and command information are automatically interpreted as leaving the work site. The vehicle is automatically covered and started moving. The status of the insulation cover is monitored in real time. If the covering fails, an alarm is triggered to remind the operator to handle the abnormal situation before the vehicle can start moving normally.

[0018] The second step: When the vehicle enters the blast furnace tapping point, cleaning point, or scrap steel adding point, the cover will be automatically opened after the vehicle arrives. If the cover fails to open, an alarm will be triggered to remind the operator to handle the abnormal situation.

[0019] The third step: When the vehicle enters the blast furnace tapping site, the cover will not open automatically after the vehicle arrives. It will open automatically after receiving the tapping forecast. If the cover fails to open, an alarm will be set to remind the operator to handle the abnormal situation.

[0020] Step 4: When the vehicle enters the steelmaking work site, the cover will not open automatically after the vehicle arrives. It will open automatically after receiving the power connection completion signal from the steelmaking side. If the cover fails to open, an alarm will be set to remind the operator to handle the abnormal situation. At the same time, an insulation cover operation panel is provided to display information such as the vehicle's arrival and cover opening status in real time. It also provides on-site operation function for opening and closing the cover at the work site, allowing steelmaking personnel to open and close the vehicle's cover according to the actual situation through the insulation cover operation panel.

[0021] Step 5: After the vehicle enters the work site, the vehicle's covered state is continuously protected. After the vehicle opens the cover at the work site, the remote cover opening and closing control function is disabled, and the open and closed status of the insulation cover is monitored in real time. If an abnormal cover is detected, an alarm is triggered to remind manual handling of the abnormal situation. Steelmaking personnel are only allowed to tilt the cover when it is open at the steelmaking work site.

[0022] Preferably, the torpedo canister is covered with its insulation cover when leaving the work site, and remains covered when entering and leaving the parking point. After entering the work site, the cover is opened before the work site begins operation.

[0023] Preferably, the control authority of the insulated cover of the torpedo tanker ensures that the local vehicle system, remote system, and work site all have the control function for opening and closing the insulated cover, and different priority settings are set for the permissions of each operating site; through the protection function of abnormal covering within the work site, it is ensured that the torpedo tanker at the work site is always in the open state when operating, and if an abnormality occurs, the system alarms and prohibits operation at the work site.

[0024] According to the present invention, an automatic lid-adding control system for molten iron transportation in a factory area controls the insulation lid of the torpedo ladle as follows:

[0025] For work-to-work station operations: after completing the work, cover the vehicle and drive away; open the cover before starting work at the next work station.

[0026] For the route from the work site to the parking point: after the work is completed, cover the vehicle and drive away; cover the parking point and keep it covered.

[0027] For the distance from the parking point to the work site: cover the parking point to keep it in place, and open the cover before starting work at the next work site;

[0028] For parking spot to parking spot: parking spots should be covered to maintain order.

[0029] Preferably, the location and access permissions for opening and closing the insulation cover are as follows:

[0030] For the control location of the vehicle itself, the control authority is either local control or remote control;

[0031] For control areas of automatic control systems, the control authority is either automatic control or manual control;

[0032] For the controlled areas of the work site, the control permissions are either remote control or manual control;

[0033] Only one control point can control the insulation cover at any given time. The control priority of the control points, from high to low, is: vehicle local > work point manual > control system manual > control system automatic. Among them, the work point manual control authority is only valid when the torpedo tanker is at the work point.

[0034] Preferably, it includes the following modules:

[0035] Module 1: When the torpedo tanker is in autonomous driving mode, the vehicle's location information and command information are automatically interpreted as leaving the work site. The vehicle is automatically covered and started moving. The status of the insulation cover is monitored in real time. If the covering fails, an alarm is triggered to remind the operator to handle the abnormal situation before the vehicle can start moving normally.

[0036] The second module: When the vehicle enters the blast furnace tapping point, cleaning point or scrap steel adding point, the cover will be automatically opened after the vehicle arrives. If the cover fails to open, an alarm will be set to remind the operator to handle the abnormal situation.

[0037] The third module: When the vehicle enters the blast furnace tapping site, the cover will not open automatically after the vehicle arrives. It will open automatically after receiving the tapping forecast. If the cover fails to open, an alarm will be set to remind the operator to handle the abnormal situation.

[0038] Module 4: When a vehicle enters the steelmaking work site, the cover will not open automatically after the vehicle arrives. It will open automatically after receiving a power connection completion signal from the steelmaking side. If the cover fails to open, an alarm will be triggered to remind personnel to handle the abnormal situation. At the same time, an insulation cover operation panel is provided to display information such as vehicle arrival and cover opening status in real time. It also provides on-site operation function for opening and closing the cover at the work site, allowing steelmaking personnel to open and close the vehicle cover through the insulation cover operation panel according to the actual situation.

[0039] Module 5: After the vehicle enters the work site, the vehicle's covered state is continuously protected. After the vehicle opens the cover at the work site, the remote cover opening and closing control function is disabled, and the open status of the insulation cover is monitored in real time. If an abnormal cover is detected, an alarm is triggered to remind manual handling of the abnormal situation. Steelmaking personnel are only allowed to tilt the cover when it is open at the steelmaking work site.

[0040] Preferably, the torpedo canister is covered with its insulation cover when leaving the work site, and remains covered when entering and leaving the parking point. After entering the work site, the cover is opened before the work site begins operation.

[0041] Preferably, the control authority of the insulated cover of the torpedo tanker ensures that the local vehicle system, remote system, and work site all have the control function for opening and closing the insulated cover, and different priority settings are set for the permissions of each operating site; through the protection function of abnormal covering within the work site, it is ensured that the torpedo tanker at the work site is always in the open state when operating, and if an abnormality occurs, the system alarms and prohibits operation at the work site.

[0042] Compared with the prior art, the present invention has the following beneficial effects:

[0043] 1. This invention targets a self-propelled, intelligent torpedo ladle car (intelligent iron mixing car) that utilizes unmanned driving technology. By adding a remote control function to the torpedo ladle car's insulation cover, the cover can be automatically opened and closed during transportation from the blast furnace to the molten steel plant while the car is driven without human intervention.

[0044] 2. The invention provides a remote automatic control switch for the insulation cover, which enables automatic opening and closing of the cover between work points and parking points, and between work points, under unmanned operation of the intelligent iron mixing vehicle. It also provides safety protection for abnormal cover application at work points, thereby reducing temperature drop and carbon emissions during molten iron transportation. It plays an important role in energy conservation and environmental protection and has great application prospects.

[0045] 3. This invention features a cover-opening / cover-closing control panel and status indicators mounted on the chassis body, along with remote system monitoring capabilities. The system, integrated with molten iron transportation processes, enables automatic cover opening / closing control and monitoring of cover status between workstations and parking points, between parking points and workstations, between workstations and workstations, and between parking points and parking points, while also providing workstation site protection. Attached Figure Description

[0046] Other features, objects, and advantages of the present invention will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings:

[0047] Figure 1 This is a flowchart illustrating the automatic lid opening and closing control method.

[0048] Figure 2 A flowchart illustrating the process of adding protective covers to work sites. Detailed Implementation

[0049] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0050] This invention provides an automatic cover control method for transporting molten iron in a factory area. When the intelligent torpedo ladle car is in automatic driving mode during molten iron transport, the automatic cover opening and closing is designed based on the principle of opening the cover only when working at the work site and closing the cover at other times, so as to keep the heat for as long as possible, thereby reducing heat loss and carbon emissions, and achieving the purpose of energy conservation and environmental protection.

[0051] The design of the control points and access permissions for opening and closing the insulation cover is as follows:

[0052]

[0053] According to the permission design, only one control location can control the insulation cover at the same time. The control priority of the control location from high to low is: vehicle local > work site manual (only effective when the vehicle is at the work site) > system manual > system automatic.

[0054] The monitoring signals of the heat insulation cover are divided into the following categories: remote control enable; opening / closing control; equipment status monitoring; equipment fault monitoring; and life signal monitoring.

[0055] There are four modes of movement for transporting molten iron in the factory area, and the corresponding automatic control for opening and closing the covers is as follows:

[0056] Work station to work station: After completing the work, cover the vehicle and drive away; open the cover before starting work at the next work station.

[0057] From work site to parking point: After completing the work, cover the vehicle and drive away; cover the parking point and keep it covered.

[0058] From parking point to work site: The parking point is covered to maintain its position, and the cover is opened before starting work at the next work site;

[0059] Parking point to parking point: Parking points are covered to maintain order.

[0060] The system automatically determines the timing for opening and closing the insulation cover by combining information such as control permissions, equipment status, life signals, and transportation details. Please see the process flow diagram below. Figure 1 .

[0061] When the vehicle is in autonomous driving mode, the system automatically interprets the vehicle's location information and command information as leaving the work site, automatically controls the covering and starts the vehicle; the system monitors the status of the insulation cover in real time, and if the covering fails, an alarm is triggered to remind the operator to handle the abnormal situation and start the vehicle normally.

[0062] When a vehicle enters the blast furnace tapping area, cleaning area, or scrap steel adding area, the cover will automatically open upon arrival. If the cover fails to open, the system will alarm to alert personnel to handle the abnormal situation.

[0063] When the vehicle enters the blast furnace tapping site, the cover will not open automatically after the vehicle arrives. It will open automatically after receiving the tapping forecast. If the cover fails to open, an alarm will be triggered to remind the operator to handle the abnormal situation.

[0064] When a vehicle enters the steelmaking work area, the cover does not automatically open upon arrival. It opens automatically only after receiving a power-on signal from the steelmaking side. If opening fails, an alarm alerts manual intervention. A control panel for the insulated cover is provided, displaying real-time information such as vehicle arrival and cover opening status. Local operation of opening and closing the cover at the work area is also provided. Steelmaking personnel can open and close the vehicle cover using the control panel according to actual conditions.

[0065] After the vehicle enters the work site, continuous protection is maintained while the vehicle is covered. Once the cover is opened at the work site, remote cover opening / closing control is disabled, and the cover's open / closed status is monitored in real time. If an abnormal cover is detected, an alarm is triggered to alert personnel to handle the situation. At the steelmaking work site, tilting operations are only permitted when the cover is open. Refer to the work site protection process flow diagram. Figure 2 .

[0066] This invention ensures that the torpedo tank is covered with its insulation cover when leaving the work site, remains covered when entering and leaving the parking point, and is opened before work begins after entering the work site. Through the control permissions of the torpedo tank's insulation cover, it ensures that the vehicle's local system, remote system, and work site all have control functions for opening and closing the insulation cover, with different priorities set for each operating location. Through the protection function against abnormal covering within the work site, it ensures that the torpedo tank is always in an open state during operation; if an abnormality occurs, the system alarms and prohibits work at the work site.

If an abnormal cover is detected, an alarm is triggered to remind manual handling of the abnormal situation. Steelmaking personnel are only allowed to tilt the cover when it is open at the steelmaking work site.

[0084] Furthermore, the torpedo tanker completes the insulation cover application when leaving the work site, maintains the covered state when entering and leaving the parking point, and opens the cover before work begins after entering the work site. Through the control permissions of the torpedo tanker's insulation cover, the system ensures that the vehicle's local system, remote system, and work site all have control functions for opening and closing the insulation cover, with different priority settings for each operating location.
