Description

Technical Field

[0001] The present invention relates to the field of metallurgy and intelligent manufacturing technology, and in particular to a redundant scheduling system, method and electronic equipment. Background Art

[0002] In the intelligent manufacturing process of the modern steel industry, data collection or data transmission is an essential function for realizing intelligent manufacturing. The stability of data collection or data transmission directly affects key links such as report calculation, model analysis and equipment control. However, industrial sites often face a variety of unstable factors such as operating system failures, network anomalies, power outages and equipment failures. These problems threaten the reliability of the underlying links, thereby causing the risk of single point failures.

[0003] At present, the relevant technologies mainly adopt cold standby or hot standby redundancy to ensure the continuity and reliability of data in the process of data collection or data transmission. The cold standby redundancy usually requires that only one main link is in operation, while the hot standby redundancy allows multiple links to run simultaneously. However, since the cold standby redundancy and the hot standby redundancy are implemented separately, after deploying one of the redundancy modes, the user can only select and use the redundancy mode, resulting in the user's selectivity being relatively single and inflexible. Therefore, the redundant scheduling system in the relevant technology is improved. Summary of the invention

[0048] Reference Figure 3 As shown, the system architecture may include a storage device 301 and a computer device 302. The computer device 302 may be at least one of a desktop graphics processing unit (GPU) computer, a GPU computing cluster, a neural network computer, etc. Relevant technicians may use the computer device 302 to determine the operating state of the first main gateway controller according to the first heartbeat signal by using the heartbeat signal of the first main gateway controller as the first heartbeat signal, and the heartbeat signal of the first standby gateway controller as the second heartbeat signal; determine the operating state of the first standby gateway controller according to the second heartbeat signal, and perform redundant scheduling on the gateway controllers in the hot standby redundant group according to the operating state of the first main gateway controller and the operating state of the first standby gateway controller.

[0050] It should be noted that the redundant scheduling method provided in the embodiment of the present application is generally executed by the computer device 302 , and accordingly, the redundant scheduling system is generally set in the computer device 302 .

[0051] The implementation details of the technical solution of the embodiment of the present application are described in detail below:

[0052] Figure 4 is a flowchart of a redundant scheduling method shown in an exemplary embodiment of the present application. The redundant scheduling method can be executed by a computing processing device. The computing processing device can be Figure 3 The computer device 302 shown in FIG. Figure 4 As shown, the redundant scheduling method at least includes steps S410 to S440, which are described in detail as follows:

[0053] In step S410, the heartbeat signal of the first main gateway controller and the heartbeat signal of the first standby gateway controller are obtained. In one embodiment of the present application, the first main gateway controller and the first standby gateway controller are both in a startup state, and the basic parameters of the gateway controller are configured, and the basic parameters include the communication protocol of the gateway controller, the redundancy group ID to which it belongs, the priority as an active gateway, the sending interval of the heartbeat signal, etc.

[0054] In step S420, the heartbeat signal of the first master gateway controller is used as the first heartbeat signal; the operating state of the first master gateway controller is determined according to the first heartbeat signal. In one embodiment of the present application, the heartbeat signal includes fields such as a redundancy group ID, a gateway ID, and a heartbeat timestamp, and the heartbeat timestamp is used to characterize the time interval for the gateway controller to send the heartbeat signal. The process of determining the operating state of the first master gateway controller according to the first heartbeat signal is implemented by an operating state determination module.

[0055] In step S430, the heartbeat signal of the first standby gateway controller is used as the second heartbeat signal; the operating state of the first standby gateway controller is determined according to the second heartbeat signal. In one embodiment of the present application, the process of determining the operating state of the first standby gateway controller according to the second heartbeat signal includes: if the second heartbeat signal includes the latest second heartbeat signal and the previous second heartbeat signal, then the time interval between the latest second heartbeat signal and the previous second heartbeat signal is calculated, recorded as the fourth time interval, and the time interval between the current moment and the timestamp of the latest second heartbeat signal is calculated, recorded as the fifth time interval; if the fourth time interval exceeds the preset interval threshold or the fifth time interval exceeds the preset time interval, the operating state of the first standby gateway controller is determined to be abnormal operation; if the fourth time interval does not exceed the preset interval threshold and the fifth time interval does not exceed the preset time interval, the operating state of the first standby gateway controller is determined to be normal operation. The process of determining the operating state of the first standby gateway controller according to the second heartbeat signal is also implemented by the operating state determination module.

[0056] In step S440, redundant scheduling is performed on the gateway controllers in the hot standby redundant group according to the operating status of the first main gateway controller and the operating status of the first standby gateway controller. In one embodiment of the present application, the process of redundant scheduling of the gateway controllers in the hot standby redundant group according to the operating status of the first main gateway controller and the operating status of the first standby gateway controller includes: if the current operating status of the first main gateway controller is abnormal operation, the active gateway is switched from the first main gateway controller to the first standby gateway controller that is operating normally; wherein, when there are multiple first standby gateway controllers that are operating normally, the latest heartbeat timestamp of each first standby gateway controller that is operating normally is obtained, the time interval between the time point corresponding to each latest heartbeat timestamp and the current moment is calculated, and the first standby gateway controller with the smallest time interval is used as the active gateway; if the current operating status of the first main gateway controller is normal operation, the first main gateway controller continues to be used as the active gateway.

[0057] In some embodiments of the present application, based on the operating status of the first main gateway controller and the operating status of the first standby gateway controller, redundant scheduling is performed on the gateway controllers in the hot standby redundant group to implement redundant scheduling and switching between the first main gateway controller and the first standby gateway controller, effectively avoiding service interruption caused by a single gateway failure, thereby ensuring that the acquisition link or transmission link maintains stable operation in a complex and changeable network environment, ensuring the continuity and integrity of user data, and improving the overall user satisfaction and trust; and when the first main gateway controller fails, quickly switching to the first standby gateway controller, reducing the need for manual intervention, greatly shortening the fault recovery time, reducing the system's operation and maintenance costs, and improving the system's overall fault tolerance and availability.

[0058] In one embodiment of the present application, the process of determining the operating state of the first master gateway controller according to the first heartbeat signal includes:

[0059] If the first heartbeat signal includes the latest heartbeat signal and the previous heartbeat signal, the time interval between the latest heartbeat signal and the previous heartbeat signal is calculated, recorded as the first time interval, and the time interval between the current moment and the timestamp of the latest heartbeat signal is calculated, recorded as the second time interval. In one embodiment of the present application, the first time interval is the time difference between the time point represented by the heartbeat timestamp in the latest heartbeat signal and the time point represented by the heartbeat timestamp in the previous heartbeat signal. The second time interval is the time difference between the current moment and the time point represented by the heartbeat timestamp in the latest heartbeat signal.

[0060] If the first time interval exceeds the preset interval threshold or the second time interval exceeds the preset time interval, the operation state of the first master gateway controller is determined to be abnormal. The preset interval threshold can be set according to actual conditions, for example, the preset interval threshold is set to 3 times the heartbeat signal sending interval.

[0061] If the first time interval does not exceed the preset interval threshold and the second time interval does not exceed the preset time interval, the operating state of the first master gateway controller is determined to be normal. In one embodiment of the present application, the operating state of the first master gateway controller is judged by the first time interval and the second time interval, so as to timely determine the latest operating state of the first master gateway controller.

[0062] In one embodiment of the present application, according to the operating state of the first main gateway controller and the operating state of the first standby gateway controller, the process of performing redundancy scheduling on the gateway controllers in the hot standby redundancy group includes:

[0063] If the current operating state of the first main gateway controller is abnormal operation, the active gateway is switched from the first main gateway controller to the first standby gateway controller that is operating normally. In one embodiment of the present application, when there are multiple first standby gateway controllers that are operating normally, the latest heartbeat timestamp of each first standby gateway controller that is operating normally is obtained, and the time interval between the time point corresponding to each latest heartbeat timestamp and the current moment is calculated, and the first standby gateway controller with the smallest time interval is used as the active gateway. Each first standby gateway controller that is operating normally sends multiple heartbeat signals, and each first standby gateway controller that is operating normally has the latest heartbeat signal, and the heartbeat timestamp in the latest heartbeat signal is the latest heartbeat timestamp.

[0064] If the current operating state of the first main gateway controller is normal, the first main gateway controller continues to be used as the active gateway. In one embodiment of the present application, in the hot standby mode, when the first main gateway controller fails, the first standby gateway controller can be quickly enabled without manual intervention, which greatly shortens the fault recovery time and improves the overall fault tolerance and availability of the system.

[0065] In one embodiment of the present application, the redundant scheduling method further includes:

[0066] Obtain the heartbeat signal of the second main gateway controller and the historical activity data of the second standby gateway controller. In one embodiment of the present application, the second main gateway controller is in a startup state, and the second standby gateway controller is in an unstarted state, that is, the cold standby redundancy group only supports a single-active mode. The historical activity data includes the startup duration and the time point of inactivity of the second standby gateway controller. The startup duration is used to characterize the startup performance of the second standby gateway controller, and the time point of inactivity is used to characterize the latest time point of the normal operation of the second standby gateway controller.

[0067] The heartbeat signal of the second main gateway controller is used as the third heartbeat signal; the operating state of the second main gateway controller is determined according to the third heartbeat signal. In one embodiment of the present application, the process of determining the operating state of the second main gateway controller according to the third heartbeat signal includes: if the third heartbeat signal includes the latest third heartbeat signal and the previous third heartbeat signal, then the time interval between the latest third heartbeat signal and the previous third heartbeat signal is calculated, recorded as the sixth time interval, and the time interval between the current moment and the timestamp of the latest third heartbeat signal is calculated, recorded as the seventh time interval; if the sixth time interval exceeds the preset interval threshold or the seventh time interval exceeds the preset time interval, the operating state of the second main gateway controller is determined to be abnormal operation; if the sixth time interval does not exceed the preset interval threshold and the seventh time interval does not exceed the preset time interval, the operating state of the second main gateway controller is determined to be normal operation. The process of determining the operating state of the second main gateway controller according to the third heartbeat signal is also implemented by the operating state determination module.

[0068] According to the operating status of the second main gateway controller and the historical activity data of the second standby gateway controller, the gateway controllers in the cold standby redundant group are redundantly scheduled. In one embodiment of the present application, according to the operating status of the second main gateway controller and the historical activity data of the second standby gateway controller, the process of redundantly scheduling the gateway controllers in the cold standby redundant group includes: if the operating status of the second main gateway controller is abnormal operation, then the startup duration and the stop activity time point of the second standby gateway controller are determined from the historical activity data; according to the startup duration and the stop activity time point, the selection weight of the second standby gateway controller is determined; and the second standby gateway controller with the largest selection weight is used as the target gateway controller; the target gateway controller is started, and the active gateway is switched from the second main gateway controller to the target gateway controller; if the operating status of the second main gateway controller is normal operation, the second main gateway controller continues to be used as the active gateway. In the cold standby mode, when the second main gateway controller fails, the second standby gateway controller can be quickly enabled without manual intervention, which greatly shortens the fault recovery time and improves the overall fault tolerance and availability of the system.

[0069] In one embodiment of the present application, the process of determining the selection weight of the second standby gateway controller according to the startup duration and the inactivity stop time point includes:

[0070] In one embodiment of the present application, the duration reference value is negatively correlated with the startup duration, that is, the longer the startup duration, the smaller the duration reference value, and the shorter the startup duration, the larger the duration reference value, thereby highlighting the superiority of the startup performance of the gateway controller.

[0071] The time interval between the current moment and the time point of stopping the activity is calculated and recorded as the third time interval, and the time reference value is determined according to the third time interval. In one embodiment of the present application, the time reference value is negatively correlated with the third time interval, that is, the larger the third time interval is, the smaller the time reference value is, and the smaller the third time interval is, the larger the time reference value is, so as to highlight the gateway controller that is closest to the current moment as the active gateway, and the gateway controller has a smaller probability of abnormality.

[0072] Based on the duration reference value and the preset duration weight, the time reference value and the preset time weight, the selection weight is determined. In one embodiment of the present application, the sum of the preset duration weight and the preset time weight is a preset value, and the preset value can be 1 or other values. The calculation process of the selection weight includes: calculating the product of the duration reference value and the preset duration weight, calculating the product of the time reference value and the preset time weight, adding the product of the duration reference value and the preset duration weight to the product of the time reference value and the preset time weight to obtain the selection weight. The second standby gateway controller with the largest selection weight has a smaller startup time and a smaller probability of abnormality. Therefore, when the second main gateway controller fails, the active gateway is switched from the second main gateway controller to the second standby gateway controller with the largest selection weight, thereby improving the switching rate and switching success rate between the second main gateway controller and the target gateway controller, greatly shortening the fault recovery time, and improving the automation and intelligence of the system.

[0073] Figure 5 is an interactive flow chart between a redundant scheduling platform and an edge gateway controller shown in an exemplary embodiment of the present application, such as Figure 5 As shown in the figure, the interaction process between the redundant scheduling platform and the edge gateway controller includes: (1) the gateway controller in the startup state sends a heartbeat signal to the redundant scheduling center; (2) the redundant scheduling center responds to the heartbeat signal of the gateway controller in the startup state; (3) it is determined whether the operation status of the redundant group is abnormal; (4) if the operation status of the redundant group is abnormal, the gateway controller is switched or the gateway controller is started first and then switched; (5) it is determined whether the gateway control is switched successfully; (6) if the gateway controller is switched successfully, the switching result of the gateway controller, the current active gateway, the operation status of the redundant group, etc. are broadcast to the gateway controller in the startup state; (7) the redundant scheduling center sends a message to the network controller in the startup state. The gateway controller sends a heartbeat signal reception success and redundant scheduling results, and the gateway controller in the startup state determines whether the active gateway is itself based on the redundant scheduling results; (8) If the gateway controller fails to switch successfully, the redundant scheduling center sends a heartbeat signal reception success and redundant scheduling results to the gateway controller in the startup state, and the gateway controller in the startup state determines whether the active gateway is itself based on the redundant scheduling results; (9) If the operating status of the redundant group is normal, the redundant scheduling center sends a heartbeat signal reception success and redundant scheduling results to the gateway controller in the startup state, and the gateway controller in the startup state determines whether the active gateway is itself based on the redundant scheduling results; (10) Respond to the redundant scheduling results.

[0074] In some embodiments of the present application, the gateway controller in the startup state includes the main link gateway controller in the hot standby redundant group, the backup link gateway controller in the hot standby redundant group, and the main link gateway controller in the cold standby redundant group. The process of judging whether the operation state of the redundant group is abnormal according to the heartbeat signal of the gateway controller in the startup state includes: judging whether the operation state of the hot standby redundant group is abnormal according to the heartbeat signal of the main link gateway controller in the hot standby redundant group and the heartbeat signal of the backup link gateway controller in the hot standby redundant group; judging whether the operation state of the cold standby redundant group is abnormal according to the heartbeat signal of the main link gateway controller in the cold standby redundant group. If the operation state of the hot standby redundant group is abnormal, switch the gateway controller; if the operation state of the cold standby redundant group is abnormal, start the gateway controller first and then switch the gateway controller.

[0075] In some embodiments of the present application, if the response of a gateway controller in a startup state times out, it can be tested by plugging and unplugging the network cable of the gateway controller in a startup state. If there is still no successful response after plugging and unplugging for a preset number of consecutive times, it is necessary to reselect an active gateway; session disconnection detection can also be performed by closing the process.

[0076] In some embodiments of the present application, after each gateway controller is started, it is not an active gateway and must be notified by the redundant scheduling center to be upgraded to an active gateway.

[0077] Figure 6 is a flowchart of redundant scheduling of gateway controllers in a redundant group shown in an exemplary embodiment of the present application. Figure 6 In the process of redundant scheduling of gateway controllers in a redundant group, the process includes: (1) performing regular detection on the operating status of the gateway controller in the redundant group that is in the startup state; (2) determining the operating status of the redundant group according to the operating status of the gateway controller in the startup state; (3) judging whether the operating status of the cold standby redundant group or the hot standby redundant group is normal; (4) if the operating status of the cold standby redundant group or the hot standby redundant group is normal, the redundant scheduling process ends; (5) if the cold standby redundant group operates abnormally, it is necessary to ensure that at least one gateway controller operates normally and is an active gateway, and shut down other gateway controllers; (6) if the hot standby redundant group operates abnormally, it is necessary to ensure that at least one gateway controller operates normally, and control other gateway controllers to be turned on or off according to the single-active mode, and control other gateway controllers to be turned on or off according to the multi-active mode; (7) broadcasting the switching result of the gateway controller, the current active gateway, the operating status of the redundant group, etc. to the gateway controller in the startup state in the redundant group.

[0078] In some embodiments of the present application, the redundancy scheduling center should set a scheduled task to regularly check the operating status of the redundancy group. If an abnormal operation of the redundancy group is detected, recovery measures should be taken immediately, such as starting a standby gateway device, switching an active gateway, or re-evaluating the operating status of the current active gateway after switching the active gateway.

[0079] In some embodiments of the present application, when the redundancy group operates normally and there is an active gateway, the industrial Internet of Things platform receives data from the active gateway and processes and stores the data. After discovering that the active gateway is operating abnormally or fails, the industrial Internet of Things platform can quickly switch to a new active gateway to ensure that data collection is not interrupted, and promptly record all state changes after switching the active gateway for subsequent analysis.

[0080] This application significantly improves the high availability, flexibility and maintainability of the system, thereby achieving the high efficiency and accuracy of the data acquisition or transmission system.
