Description

Technical Field

[0001] The present application relates to the field of industrial automation technology, and more specifically, to a configuration update method, device, electronic device, and storage medium for a cloud control system. Background Art

[0002] In traditional industrial control systems, configuration downloads use a serial transmission mode from configuration software to controller to communication card. This process is time-consuming and can result in data interruptions lasting 10-30 seconds during configuration updates, severely impacting the real-time nature of production. Cloud-based control systems, on the other hand, utilize a completely new architecture, centrally deploying cloud-based controllers and cloud-based configuration services on servers in the intelligent control center, while communication cards are independently deployed on-site. This distributed architecture breaks down the configuration download process into two independent steps: first updating the communication card configuration before updating the controller configuration, or first updating the controller configuration before updating the communication card configuration. This process takes less than 100ms, effectively minimizing the impact on real-time production.

[0003] However, because the PROFINET data collection protocol uses a tightly packed, non-self-explanatory binary encoding scheme, the memory layout of the PROFINET data changes after the communication card completes a configuration update. If the controller has not yet completed the corresponding configuration update, the controller's parsing of the collected data will be misaligned, resulting in abnormal jumps in input and output data. This condition persists until the controller completes the configuration update and is fully consistent with the communication card. This issue poses a significant risk in industrial control systems, potentially causing fluctuations in production processes and even equipment failures, posing a serious threat to the stable operation of industrial systems. Summary of the Invention

[0004] In view of this, the present application provides a configuration update method, device, electronic device and storage medium for a cloud control system, which are used to solve the problem of abnormal jumps in input and output data during the configuration update process of the cloud control system, so as to avoid serious threats to the stable operation of the industrial system.

[0041] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0042] The present application provides a configuration update method, device, electronic device and storage medium for a cloud control system. The cloud control system here includes at least a communication card, a PN slave station and multiple slots, each slot is configured with multiple sub-slots, and each sub-slot is connected to a controller, such as Figure 1 Based on the cloud control system, the following specific embodiments are proposed.

[0043] Figure 2 This is a flow chart of a configuration update method for a cloud control system according to an embodiment of the present application.

[0044] like Figure 2 As shown, the configuration update method provided in this embodiment is applied to an electronic device for performing configuration update processing on a cloud control system. The electronic device can be understood as a computer, server or cloud platform with data computing and information processing capabilities. The configuration update method specifically includes the following steps:

[0045] S1. Download configuration update information to the communication card according to the system's configuration update request.

[0046] In other words, in response to a configuration update request issued by the user or automatically generated by the system, the host computer or cloud platform downloads the configuration update information to the communication card. After downloading the configuration update information, the communication card automatically or under user control performs the configuration update operation on the communication card. The configuration update operation causes the communication card to perform multicast data push to the controller based on the data format specified by the configuration update information.

[0047] S2. Synchronously send configuration update information to each controller via multicast.

[0048] That is, when the communication card downloads the configuration update information and performs the configuration update operation or after completing the configuration update processing, the configuration update information is sent to each controller via multicast, so that after receiving the configuration update information, each controller performs a configuration update operation on itself based on the configuration update information, so that it can correctly parse the multicast data sent by the communication card.

[0049] S3. After the communication card completes sending the configuration update information, the multicast data push is immediately resumed.

[0050] That is, after executing the multicast configuration update information, the communication card immediately executes the multicast data push. Because the multicast time of this more detailed configuration information is extremely short, the configuration update process is even shorter, approximately 1-2μs. This immediate resumption of multicast data push does not affect the controller's reception and correct parsing of the multicast data. In addition, in this application, the following specific operations are implemented to implement the resumption of multicast data push.

[0051] On the one hand, if Figure 3 As shown in the figure, if the communication card does not send multicast data during the controller configuration update process, the controller processes the subsequently received multicast data according to the latest version.

[0052] On the other hand, Figure 4 As shown in the figure, if the communication card sends multicast data while the controller is performing a configuration update, the controller first performs the configuration update operation and then processes the subsequently received multicast data according to the latest version.

[0053] As can be seen from the above technical solution, this embodiment provides a configuration update method for a cloud control system. The method is applied to electronic equipment. The cloud control system includes at least one communication card and multiple controllers connected to the communication card. The specific update solution is to respond to the system's configuration update request, download configuration update information to the communication card, so that the communication card performs a configuration update operation based on the configuration update information; while the communication card implements the configuration update, it synchronously sends the configuration update information to each controller via multicast, so that the controller synchronously performs the configuration update operation according to the configuration update information; after the communication card completes sending the configuration update information, it immediately resumes multicast data push. This solution can achieve synchronous configuration updates of the communication card and the controller in a very short time, thereby solving the problem of abnormal jumps in input and output data during the configuration update process of the cloud control system and avoiding threats to the stable operation of the industrial system.

[0054] In a specific implementation of the embodiment of the present application, the following steps are also included: Figure 5 shown.

[0055] S4. When the configuration update information is lost, the configuration update information is sent again.

[0056] When the controller detects that the currently running configuration version is different from the version of the received multicast data, it can be determined that the controller lost packets when receiving the communication card sending the configuration update information, resulting in the failure to complete the configuration update. In order to avoid abnormal jumps in input and output data, a configuration synchronization request is sent to the communication card at this time. Based on the request, the communication card sends the configuration update information to each controller again through multicast. The controller that did not issue the configuration synchronization request can ignore the information and only spends a negligible amount of time to receive the information. This reception does not affect the reception of multicast data. Only the controller that issued the configuration synchronization request performs the configuration update operation based on the configuration update information, thereby completing the configuration update. The specific execution process is as follows. Figure 6 shown.

[0058] Although the operations are depicted in a particular order, this should not be understood as requiring that the operations be performed in the particular order shown or in a sequential order.Multitasking and parallel processing may be advantageous under certain circumstances.

[0059] It should be understood that the various steps described in the method embodiments of the present disclosure may be performed in different orders and / or in parallel.

In cases involving a remote computer, the remote computer may be connected to the user's computer via any type of network, including a local area network (LAN) or a wide area network (WAN), or may be connected to an external computer.

[0061] Figure 7 This is a block diagram of a configuration update device for a cloud control system according to an embodiment of the present application.

[0062] like Figure 7 As shown, the configuration update device provided in this embodiment is applied to an electronic device for performing configuration update processing on a cloud-based control system. The electronic device can be understood as a computer, server, or cloud platform with data computing and information processing capabilities. The configuration update device specifically includes a configuration download module 10, a multicast control module 20, and a push control module 30.

[0063] The configuration download module is used to download configuration update information to the communication card according to the system's configuration update request.

[0064] In other words, in response to a configuration update request issued by the user or automatically generated by the system, the host computer or cloud platform downloads the configuration update information to the communication card. After downloading the configuration update information, the communication card automatically or under user control performs the configuration update operation on the communication card. The configuration update operation causes the communication card to perform multicast data push to the controller based on the data format specified by the configuration update information.

[0065] The multicast control module is used to synchronously send configuration update information to each controller via multicast.

[0066] That is, when the communication card downloads the configuration update information and performs the configuration update operation or after completing the configuration update processing, the configuration update information is sent to each controller via multicast, so that after receiving the configuration update information, each controller performs a configuration update operation on itself based on the configuration update information, so that it can correctly parse the multicast data sent by the communication card.

[0067] The push control module is used to resume multicast data push immediately after the communication card completes sending the configuration update information.

[0068] That is, after executing the multicast configuration update information, the communication card immediately executes the multicast data push. Because the multicast time of this more detailed configuration information is extremely short, the configuration update process is even shorter, approximately 1-2μs. This immediate resumption of multicast data push does not affect the controller's reception and correct parsing of the multicast data. In addition, the push control module in this application specifically implements the following method for resuming multicast data push.

[0069] On the one hand, if Figure 3 As shown in the figure, if the communication card does not send multicast data during the controller configuration update process, the controller processes the subsequently received multicast data according to the latest version.

[0070] On the other hand, Figure 4 As shown in the figure, if the communication card sends multicast data while the controller is performing a configuration update, the controller first performs the configuration update operation and then processes the subsequently received multicast data according to the latest version.

[0071] As can be seen from the above technical solution, this embodiment provides a configuration update device for a cloud control system, which is applied to electronic equipment. The cloud control system includes at least one communication card and multiple controllers connected to the communication card. The specific update solution is to respond to the system's configuration update request, download configuration update information to the communication card, so that the communication card performs a configuration update operation based on the configuration update information; while the communication card implements the configuration update, it synchronously sends the configuration update information to each controller via multicast, so that the controller synchronously performs the configuration update operation according to the configuration update information; after the communication card completes sending the configuration update information, it immediately resumes multicast data push. This solution can achieve synchronous configuration updates of the communication card and the controller in a very short time, thereby solving the problem of abnormal jumps in input and output data during the configuration update process of the cloud control system and avoiding threats to the stable operation of the industrial system.

[0072] In a specific implementation of the embodiment of the present application, a synchronization request module 40 is also included, such as Figure 8 shown.

[0073] The synchronization request module is used to resend the configuration update information when the configuration update information is lost.

[0074] When the controller detects that the currently running configuration version is different from the version of the received multicast data, it can be determined that the controller lost packets when receiving the communication card sending the configuration update information, resulting in the failure to complete the configuration update. In order to avoid abnormal jumps in input and output data, a configuration synchronization request is sent to the communication card at this time. Based on the request, the communication card sends the configuration update information to each controller again through multicast. The controller that did not issue the configuration synchronization request can ignore the information and only spends a negligible amount of time to receive the information. This reception does not affect the reception of multicast data. Only the controller that issued the configuration synchronization request performs the configuration update operation based on the configuration update information, thereby completing the configuration update. The specific execution process is as follows. Figure 6 shown.

[0075] The units involved in the embodiments described in this disclosure may be implemented in software or hardware. In some cases, the name of a unit does not limit the unit itself. For example, the first acquisition unit may also be described as a "unit for acquiring at least two Internet Protocol addresses."

When the one or more computer programs are executed by the electronic device, the electronic device responds to the system's configuration update request and downloads configuration update information to the communication card, so that the communication card performs configuration update operations based on the configuration update information. While the communication card is performing the configuration update, the configuration update information is synchronously sent to each controller via multicast, so that the controller synchronously performs configuration update operations based on the configuration update information. After the communication card completes sending the configuration update information, the multicast data push is immediately resumed. This solution enables the communication card and controller to achieve synchronous configuration updates in a very short time, thereby solving the problem of abnormal jumps in input and output data during the configuration update process of the cloud control system and avoiding threats to the stable operation of the industrial system.
