Description

Technical Field

[0001] The present application relates to a data processing method, device, electronic equipment and storage medium, and belongs to the field of industrial data collection. Background Art

[0002] At present, multiple industrial protocol standards coexist, which are not unified and incompatible with each other, resulting in difficulties in protocol parsing, data format conversion and data interconnection.

[0003] Protocol conversion technology converts different industrial communication protocols into a unified protocol through technical means such as protocol analysis, data conversion, and address space remapping, so as to achieve information interaction of device data collection and interconnection with information systems. Commonly used industrial protocols reduce the difficulty of device networking through protocol conversion and achieve unified access.

[0004] Under the strong promotion of the OPC Foundation, the OPC protocol was proposed to standardize the software interface between devices and applications from different suppliers and simplify the data exchange. However, the OPC technology based on COM / DCOM has an ineradicable disadvantage and can only run on the Windows platform. Therefore, with the advancement of technology and the increase in various requirements for data exchange, the OPC Foundation released a new specification in 2008: OPC UA. The old version of the host computer software that only supports the OPC protocol has not kept up with the times and does not support the OPC UA protocol. In this case, there is a lot of room for application in converting OPC UA to OPCDA (data access based on the OPC standard). Summary of the invention

[0007] Furthermore, in response to the OPC UA service connection being successful, before obtaining a preset configuration model based on the NodeID of the address space, the method further includes: connecting to the OPC UA service based on OPC UA connection authentication parameters.

[0008] Furthermore, the OPC UA connection authentication parameters include: connection URL; security mode; security policy; account number and password.

[0009] Further, connecting to the OPC UA service based on the OPC UA connection authentication parameters includes: connecting to the OPC UA service based on the OPC UA connection authentication parameters and a disconnection reconnection model.

[0023] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0024] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0025] The inventors found that some device versions are old and only support the OPCDA protocol, but not the OPCUA protocol. When devices supporting the OPCUA protocol and devices supporting the OPCDA protocol are in the same node cluster, it is necessary to unify their data protocols to achieve information interaction of device data collection and interconnection with the information system. To this end, a solution for converting the OPCUA protocol to the OPCDA protocol is proposed to meet the needs of specific software applications. The specific implementation plan is as follows:

[0026] Embodiment 1:

[0027] Figure 1 A flowchart of a data processing method provided in an embodiment of the present application is shown as follows: Figure 1 As shown, the method may include the following steps:

[0028] 101 responds to the OPC UA service connection successfully, and obtains the preset configuration model based on the NodeID of the address space.

[0029] Among them, OPCUA's NodeID contains the following parts:

[0030] 1) Namespace Index: Identifies the namespace to which the node belongs.

[0031] 2) Node Identifier: A string or numeric value that uniquely identifies a node.

[0032] 3) Node identifier type: Identifies the type of the node identifier, such as string, integer, GUID, etc.

[0033] It should be noted that NodeId is one of the key elements in building the OPCUA configuration model. In the configuration model, by reasonably defining and editing NodeId, the various nodes in the model and their relationships can be determined. For example, when creating an object-type node set with variables and methods, NodeId is used to clarify the position of each node in the entire configuration model, including object nodes, variable nodes, method nodes, etc. Take the creation of a configuration model for an industrial monitoring system that contains multiple sensor data collection points as an example. The node corresponding to each sensor has a unique NodeId. The definition of these NodeIds (such as encoding according to the physical location of the sensor, functional type, etc.) determines the structure and data flow of the entire monitoring system configuration model.

[0034] As an optional implementation, connect to the OPC UA service, and after successful connection, filter the NodeID of the address space, generate a configuration model, and save it in a specified format.

[0035] For example, developers can implement flexible editing of NodeId by using model design tools or writing scripts to automatically generate codes.

[0036] In some embodiments, the responding to the successful connection of the OPC UA service, before obtaining a preset configuration model based on the NodeID of the address space, further includes: connecting to the OPC UA service based on the OPC UA connection authentication parameters.

[0037] Specifically, Figure 2 As shown, in order to generate a configuration model, the OPC UA service is connected according to the OPC UA connection authentication parameters, including the connection URL, security mode, security policy, account number and password.

[0038] Among them, the security policy is configured to scan automatically.

[0039] In some embodiments, connecting to the OPC UA service based on the OPC UA connection authentication parameters includes: connecting to the OPC UA service based on the OPC UA connection authentication parameters and a disconnection reconnection model.

[0040] It should be noted that different reconnection models are used for different OPC UA services, which are not limited here.

[0041] In some embodiments, the disconnection reconnection model is configured to be short at the beginning and long at the end.

[0042] Specifically, the target device is accessed in a short connection mode within the first preset time, and the target device is accessed in a long connection mode within the second preset time. The target device can be a server or another client device. The disconnection reconnection model is set to short first and long later, which can avoid resource waste and improve software performance.

[0043] In one embodiment, the configuration model includes multiple different OPC UA services to achieve simultaneous conversion of multiple services.

[0044] 102 Publish the OPCDA service based on the configuration model to create a tag.

[0045] It should be noted that the basic condition for creating an OPCDA tag is to obtain the address of the target node. This is because the tag is associated with a specific node. The configuration model can provide unique information about the node address. Therefore, in some embodiments, Figure 3 As shown, the publishing of OPCDA service based on the configuration model to create a tag includes: publishing OPCDA service based on the configuration model and generating OPCDA node information; creating a tag based on the OPCDA node information. Generally speaking, an OPCDA tag includes information such as data value, data quality, and timestamp.

[0046] Exemplarily, the step of creating a tag may include:

[0047] Step 1. Connect to the OPCDA server: Use the client software to connect to the OPCDA server;

[0048] Step 2. Navigate to the desired tag: Once connected, start browsing tags on the server through API functions or tools;

[0049] Step 3. Create a new tag: After selecting or navigating to the target tag, perform the creation operation. This usually involves setting the tag's name, data type, and other related properties.

[0050] 103 reads the first value of the NodeID of the configuration model.

[0051] 104 updates the second value of the tag based on the first value.

[0052] In this embodiment, the value of the NodeID of the OPC UA configuration model is read, and the value of the corresponding OPC DA tag is continuously updated, thereby realizing the conversion of the protocol. The value may represent exchange data, and this embodiment does not limit the specific data type.

[0053] In some embodiments, the OPCDA service is an SDK-registered OPCDA service provided by the OPC Foundation.

[0054] It is worth noting that according to the configuration model, based on the SDK provided by the OPC Foundation, OPCDA services can be published without relying on other applications, and the application software reads the published tag information based on the service name.

[0055] In an actual application, the server responds to the successful connection of the OPCUA service, obtains a preset configuration model based on the NodeID of the address space, and the configuration model includes characteristic data of each node; the server publishes the OPCDA service based on the configuration model to create labels for each node; the server reads the first value of the NodeID of the configuration model; and the server updates the second value of the label based on the first value.

[0056] In another practical application, the cluster master control device responds to the successful connection of the OPCUA service, obtains a preset configuration model based on the NodeID of the address space, and the configuration model contains characteristic data of each node; the master control device publishes the OPCDA service based on the configuration model to create labels for each node; the master control device reads the first value of the NodeID of the configuration model; the master control device updates the second value of the label based on the first value.

[0061] The reading module 403 is configured to read the first value of the NodeID of the configuration model.

[0062] The updating module 404 is configured to update the second value of the tag based on the first value.

[0063] In some embodiments, the responding to the successful connection of the OPC UA service, before obtaining a preset configuration model based on the NodeID of the address space, further includes: connecting to the OPC UA service based on the OPC UA connection authentication parameters.

[0064] In some embodiments, the OPC UA connection authentication parameters include: connection URL; security mode; security policy; account number and password.

[0065] In some embodiments, connecting to the OPC UA service based on the OPC UA connection authentication parameters includes: connecting to the OPC UA service based on the OPC UA connection authentication parameters and a disconnection reconnection model.
