Description

Technical Field

[0001] This application relates to the field of iron and steel metallurgy technology, and in particular to a method, apparatus and electronic equipment for switching communication between domains of a rotary annealing furnace. Background Technology

[0002] Currently, with social development and technological progress, industrial rotary annealing furnaces are gradually being used in the continuous annealing process of whole coil steel at different process temperatures. They are complex systems that integrate mechanical, electrical and distributed control systems (DCS), and have the rotatability that conventional annealing furnaces do not possess. Rotary annealing furnaces are mainly used for the production of grain-oriented silicon steel.

[0003] However, due to the high magnetic induction and excellent magnetic properties of grain-oriented silicon steel, the wireless network deployed in the annealing furnace area is greatly affected by magnetic field interference and is very unstable. In addition, traditional communication methods may use manually switched wired communication for data transmission. When the rotary annealing furnace is rotated to a specific position, the communication cable needs to be manually disconnected, and then the cable needs to be restored to its initial position and manually reconnected to the moving side of the rotary annealing furnace. This will cause a brief interruption in inter-domain communication, creating a data exchange blind spot, which is not conducive to the stable operation of the control system and reduces the reliability of communication. Summary of the Invention

When the trolley moves from the preset movable position range to the specified preset boundary position, it is determined that the communication connection between the movable joint and the trolley joint will be switched to the communication connection between the fixed joint and the trolley joint. The movable joint and the fixed joint are both connected to the trolley joint through a redundant network.

[0006] In one feasible implementation, after determining that the communication connection between the movable joint and the trolley joint will be switched to the communication connection between the fixed joint and the trolley joint when the trolley moves from the preset movable position range to a predetermined preset boundary position, the method further includes: After the connector is switched from the movable connector to the fixed connector, the movable connector is controlled to move to the initial position of the preset movable position range; When the movable joint is detected to be in the initial position, it is determined that the communication connection between the fixed joint and the trolley joint will be switched back to the communication connection between the movable joint and the trolley joint.

Disconnect the communication connection between the second network male connector of the movable connector and the female connector of the trolley connector; Establish a communication connection between the second network male connector of the fixed connector and the female connector of the trolley connector.

[0010] In one feasible implementation, determining to switch the communication connection between the fixed connector and the trolley connector back to the communication connection between the mobile connector and the trolley connector when the mobile connector is detected to be in the initial position includes: When the movable connector is detected to be in the initial position, it is determined to cut off the communication connection between the first network male connector of the fixed connector and the female connector of the trolley connector, and to cut off the communication connection between the Ethernet male connector and the female connector of the trolley connector.

Disconnect the communication connection between the second network male connector of the movable connector and the female connector of the trolley connector; Establish a communication connection between the second network male connector of the fixed connector and the female connector of the trolley connector.

[0011] In one feasible implementation, the real-time position of the trolley on the moving side of the rotary annealing furnace relative to the fixed side is obtained by the following method: The position signal of the trolley relative to the fixed side is acquired based on the distance sensor installed on the rotating track of the trolley; Based on the mapping relationship between the position signal and the preset position code, the real-time position of the trolley on the moving side of the rotary annealing furnace relative to the fixed side is generated.

[0020] First, the applicable application scenarios of this application will be introduced. The embodiments provided in this application are applicable to the field of iron and steel metallurgy technology.

[0021] Currently, due to the high magnetic induction and excellent magnetic properties of grain-oriented silicon steel, wireless networks deployed within the annealing furnace area are significantly affected by magnetic field interference, making them highly unstable. Furthermore, traditional communication methods may involve manually switching wired communication for data transmission. When the rotary annealing furnace is rotated to a specific position, the communication cable needs to be manually disconnected, then restored to its initial position, and manually reconnected to the moving side of the rotary annealing furnace. This results in a brief interruption of inter-domain communication, creating a data exchange blind spot, which is detrimental to the stable operation of the control system and reduces communication reliability.

[0022] Based on this, the embodiments of this application provide a method, apparatus and electronic device for switching communication between domains of a rotary annealing furnace. The embodiments provided by this application solve the technical problems of unstable data communication transmission, which is not conducive to the stable operation of the control system and reduces the reliability of communication in the prior art. The embodiments provided by this application achieve continuous wired communication between the fixed side and the moving side by switching the communication connection between the moving connector and the trolley connector to the communication connection between the fixed connector and the trolley connector, thereby improving the stability and reliability of the transmission data of the control system.

[0023] Figure 1 This illustration shows a schematic diagram of a switching application for inter-domain communication in a rotary annealing furnace according to an embodiment of this application. Figure 1 As shown, the rotary annealing furnace in the embodiments provided in this application includes a fixed side and a movable side. The fixed side includes a central rotating shaft, and the movable side includes a trolley. A fixed joint and a movable joint are installed on the central rotating shaft.

[0024] In the above-mentioned embodiments, the rotary annealing furnace provided in this application is divided into two domains: a fixed side and a moving side. The fixed side mainly includes the furnace shell, the central rotating shaft, and the combustion loop, etc., and its physical position is fixed. The moving side mainly includes the trolley and the protective gas valve platform, etc., and its physical position changes as the trolley rotates. In the embodiments provided in this application, a fixed connector and a moving connector are installed on the central rotating shaft. The fixed connector network male connector in the fixed connector and the moving connector network male connector in the moving connector are connected from top to bottom to a first network male connector, a second network male connector, and an Ethernet male connector. The trolley connector is fixedly installed with a female connector of the trolley connector.

[0025] In the above-described embodiments provided in this application, the first network connector and the second network connector are redundant data transmission connectors.

[0026] It is understood that the preset movable position range specified in the embodiments provided in this application is specifically position 5.

[0027] The rotary annealing furnace in the embodiments provided in this application is a heat treatment device for metal processing, mainly used to improve the mechanical properties of materials.

[0028] Figure 2 This is a flowchart illustrating the switching of inter-domain communication in a rotary annealing furnace, as provided in an embodiment of this application. Figure 2 As shown, the switching method for inter-domain communication in a rotary annealing furnace includes the following steps: S201. For any car, obtain the real-time position of the car on the moving side of the rotary annealing furnace relative to the fixed side.

[0029] In this step, before the embodiments provided in this application need to transmit data between the domains of the rotary annealing furnace, it is first necessary to obtain the real-time position of the trolley on the moving side of the rotary annealing furnace relative to the fixed side, and determine whether the real-time position is located in the general position, i.e., between position 0 and position 4, or at the preset boundary position, i.e., position 5.

[0030] S202. Based on the real-time location, determine whether the trolley on the mobile side is within the specified preset movable position range.

[0031] In this step, after determining the real-time position of the trolley on the moving side relative to the fixed side, the embodiment provided in this application needs to determine whether the trolley is in the preset movable position range of position 0 to position 5.

[0032] It is understood that the preset movable position range in the embodiments provided in this application can be customized and used according to different application scenarios and usage conditions.

[0033] For example, the preset movable location range is determined by the following methods: Based on the furnace enclosure area corresponding to the fixed side of the rotary annealing furnace and the number of trolleys matching the rotary annealing furnace, the furnace enclosure area is divided to determine the specified preset movable position range.

[0034] It should be noted that the preset movable position range in the embodiments provided in this application is determined based on the quotient between the furnace enclosure area corresponding to the fixed side of the rotary annealing furnace and the number of trolleys matching the rotary annealing furnace.

[0035] S203. If so, then confirm that the movable joint on the fixed side is connected to the trolley joint on the movable side.

[0036] In this step, if it is determined that the trolley on the mobile side is within the specified preset movable position range, then it is necessary to connect the mobile connector on the fixed side to the trolley connector on the mobile side to achieve direct connection of the network connector, thereby realizing wired communication between the fixed side and the mobile side.

[0037] For example, communicating between the movable joint on the fixed side and the trolley joint on the movable side includes: The male connector of the movable connector on the fixed side is physically connected to the female connector of the trolley connector on the movable side; power is supplied to the three sets of network male connectors in the male connector of the movable connector to realize the communication connection between the movable connector on the fixed side and the trolley connector on the movable side. The three sets of network male connectors include a first network male connector, a second network male connector and an Ethernet male connector. The first network male connector and the second network male connector are redundant networks for data transmission.

[0038] Among them, the three sets of network male connectors maintain this communication connection state between positions 0 and 4, that is, in the normal position.

[0039] S204. When the trolley moves from the preset movable position range to the specified preset boundary position, it is determined that the communication connection between the movable joint and the trolley joint will be switched to the communication connection between the fixed joint and the trolley joint. Both the movable joint and the fixed joint are based on the redundant network to communicate with the trolley joint.

[0040] In this step, when the trolley moves from the preset movable position range to the specified preset boundary position, i.e., position 5, the redundancy characteristics of the first network male connector Vnet1 and the second network male connector Vnet2 are utilized, and at the same time, the fixed connector with network switching is used to realize a brief wired communication, that is, to determine that the communication connection between the movable connector and the trolley connector will be switched to the communication connection between the fixed connector and the trolley connector.

[0041] For example, when the trolley moves from a preset movable position range to a predetermined preset boundary position, it is determined that the communication connection between the movable joint and the trolley joint will be switched to the communication connection between the fixed joint and the trolley joint, including: When the trolley moves from the preset movable position range to the specified preset boundary position, the communication connection between the first network male connector of the movable connector and the female connector of the trolley connector is cut off, and the communication connection between the Ethernet male connector and the female connector of the trolley connector is cut off; the communication connection between the first network male connector of the fixed connector and the female connector of the trolley connector is connected, and the communication connection between the Ethernet male connector and the female connector of the trolley connector is connected; the communication connection between the second network male connector of the movable connector and the female connector of the trolley connector is cut off; and the communication connection between the second network male connector of the fixed connector and the female connector of the trolley connector is connected.

[0042] In the above-described embodiment, when the trolley moves from a preset movable position range to a specified preset boundary position, the Vnet1 of the movable connector and the Ethernet male connector are first de-energized, then the Vnet1 of the fixed connector is connected to the female connector of the trolley connector, and then the Vnet2 of the movable connector is cut off, and the communication connection between the Vnet2 of the fixed connector and the female connector of the trolley connector is established. In this way, the three networks are switched to the fixed connector control.

[0043] For example, after the connector is switched from a movable connector to a fixed connector, the movable connector is controlled to move to an initial position within a preset movable position range; when the movable connector is detected to be in the initial position, it is determined that the communication connection between the fixed connector and the trolley connector will be switched back to the communication connection between the movable connector and the trolley connector.

[0044] In the above-described embodiment, after the movable connector returns to its initial position 0, the network communication is switched back to the communication connection with the trolley connector and then switched back to the movable connector to restore the direct connection of the movable connector in the normal position. This cycle repeats, and the connector is automatically switched once every 5 positions the trolley moves, thereby realizing continuous, stable and convenient wired communication between the fixed and movable sides.

[0045] In the above process, when the movable connector is detected to be in its initial position, the communication connection between the first network male connector of the movable connector and the female connector of the trolley connector is cut off, and the communication connection between the Ethernet male connector and the female connector of the trolley connector is also cut off; the communication connection between the first network male connector of the fixed connector and the female connector of the trolley connector is connected, and the communication connection between the Ethernet male connector and the female connector of the trolley connector is also connected; the communication connection between the second network male connector of the movable connector and the female connector of the trolley connector is cut off; and the communication connection between the second network male connector of the fixed connector and the female connector of the trolley connector is connected.

[0046] It should be noted that, in the embodiments provided in this application, when the movable connector is detected to be in the initial position, the Vnet1 of the fixed connector and the Ethernet male connector are first de-energized, then the Vnet1 of the movable connector is connected to the female connector of the trolley connector, and then the Vnet2 of the fixed connector is cut off, and the communication connection between the Vnet2 of the movable connector and the female connector of the trolley connector is connected. In this way, the three networks are switched to the fixed connector control.

[0047] For example, the real-time position of the trolley on the moving side of a rotary annealing furnace relative to the fixed side is obtained in the following manner: The position signal of the trolley relative to the fixed side is collected by a distance sensor installed on the rotating track of the trolley; based on the mapping relationship between the position signal and the preset position code, the real-time position of the trolley on the moving side of the rotary annealing furnace relative to the fixed side is generated.

[0048] It should be noted that the distance sensor in the embodiments provided in this application can be customized and used according to different application scenarios.

[0049] During network switching operations, the power-off and power-on actions of the general network and the special network are executed alternately; during network reconnection operations, after the power-off action of the same group network of the fixed connector and the mobile connector is completed, the power-on action of the corresponding mobile connector's same group network is immediately triggered.

[0050] Compared with the prior art, the switching method for inter-domain communication in a rotary annealing furnace provided in this application determines whether the trolley on the moving side is within a predetermined preset movable position range based on the real-time position of the trolley on the moving side relative to the fixed side in the rotary annealing furnace. Then, when the trolley is determined to be within the predetermined preset movable position range, a communication connection is established between the moving connector on the fixed side and the trolley connector on the moving side. Finally, when the trolley moves from the predetermined movable position range to a predetermined preset boundary position, the communication connection is switched from the moving connector to the trolley connector to the fixed connector. This embodiment achieves continuous wired communication between the fixed and moving sides by switching the communication connection between the moving connector and the trolley connector to the fixed connector, improving the stability and reliability of data transmission in the control system. Furthermore, during network switching, one of the moving connector and the fixed connector remains connected, thus ensuring the continuity of inter-domain communication between the fixed and moving sides.

[0051] Figure 3 This is a structural block diagram of a switching device for inter-domain communication in a rotary annealing furnace, provided in an embodiment of this application. Figure 3 As shown, the rotary annealing furnace includes a fixed side and a moving side. The fixed side includes a central rotating shaft, and the moving side includes a trolley. A fixed joint and a moving joint are mounted on the central rotating shaft. The switching device 300 for inter-domain communication of the rotary annealing furnace includes: The acquisition module 310 is used to acquire the real-time position of the trolley on the moving side of the rotary annealing furnace relative to the fixed side for any trolley.

[0052] The first determining module 320 is used to determine, based on the real-time position, whether the trolley on the moving side is within a specified preset movable position range.

[0053] The second determining module 330 is used to determine, if so, that the movable joint in the fixed side and the trolley joint in the movable side will be connected in communication.

[0054] The third determining module 340 is used to determine whether to switch the communication connection between the moving joint and the trolley joint to the fixed joint and the trolley joint when the trolley moves from the preset movable position range to the specified preset boundary position. Both the moving joint and the fixed joint are based on a redundant network to communicate with the trolley joint.

[0055] The control module 350 is used to control the movable joint to move to the initial position of the preset movable position range after the joint has been switched from a movable joint to a fixed joint.

[0056] The fourth determining module 360 ​​is used to determine, when the movable joint is detected to be in the initial position, to switch the communication connection between the fixed joint and the trolley joint back to the communication connection between the movable joint and the trolley joint.

[0057] For example, the acquisition module 310 is used to determine a preset movable position range by means of: Based on the furnace enclosure area corresponding to the fixed side of the rotary annealing furnace and the number of trolleys matching the rotary annealing furnace, the furnace enclosure area is divided to determine the specified preset movable position range.

[0058] For example, the second determining module 330 is specifically used for: Physically connect the male connector of the movable joint on the fixed side with the female connector of the trolley joint on the movable side.

[0059] Power is supplied to three sets of network male connectors in the male connector of the mobile connector to enable communication between the mobile connector on the fixed side and the trolley connector on the mobile side. The three sets of network male connectors include a first network male connector, a second network male connector, and an Ethernet male connector. The first network male connector and the second network male connector are redundant networks.

[0060] For example, the third determining module 340 is specifically used for: When the trolley moves from the preset movable position range to the specified preset boundary position, it determines to cut off the communication connection between the first network male connector of the movable connector and the female connector of the trolley connector, and to cut off the communication connection between the Ethernet male connector and the female connector of the trolley connector.

[0061] The first network male connector of the conductive fixed connector is connected to the female connector of the trolley connector, and the communication connection between the Ethernet male connector and the female connector of the trolley connector is established.

[0062] Disconnect the communication connection between the second network male connector of the moving connector and the female connector of the trolley connector.

[0063] The communication connection between the second network male connector of the conductive fixed connector and the female connector of the trolley connector is established.

[0064] For example, when the movable joint is detected to be in the initial position, determining to switch the communication connection between the fixed joint and the trolley joint back to the communication connection between the movable joint and the trolley joint includes: When the moving connector is detected to be in the initial position, the communication connection between the first network male connector of the fixed connector and the female connector of the trolley connector is determined to be cut off, and the communication connection between the Ethernet male connector and the female connector of the trolley connector is cut off.

[0065] The first network male connector of the conductive fixed connector is connected to the female connector of the trolley connector, and the communication connection between the Ethernet male connector and the female connector of the trolley connector is established.

[0066] Disconnect the communication connection between the second network male connector of the moving connector and the female connector of the trolley connector.

[0067] The communication connection between the second network male connector of the conductive fixed connector and the female connector of the trolley connector is established.

[0068] For example, the real-time position of the trolley on the moving side of a rotary annealing furnace relative to the fixed side is obtained in the following manner: The position signal of the trolley relative to the fixed side is collected by a distance sensor installed on the rotating track of the trolley.

[0069] Based on the mapping relationship between position signals and preset position codes, the real-time position of the trolley on the moving side of the rotary annealing furnace relative to the fixed side is generated.

[0070] The switching device 300 for inter-domain communication of a rotary annealing furnace provided in this application embodiment, compared with the prior art, determines whether the trolley on the moving side is within a predetermined preset movable position range based on the real-time position of the trolley on the moving side relative to the fixed side in the rotary annealing furnace. Then, when it is determined that the trolley on the moving side is within the predetermined preset movable position range, it determines to establish a communication connection between the moving connector on the fixed side and the trolley connector on the moving side. Then, when the trolley moves from the predetermined movable position range to a predetermined preset boundary position, it determines to switch the communication connection from the moving connector to the trolley connector to the fixed connector to the trolley connector. By switching the communication connection from the moving connector to the trolley connector to the fixed connector to the trolley connector, the embodiment provided in this application achieves continuous wired communication between the fixed side and the moving side, improving the stability and reliability of data transmission in the control system.
