Description

Technical Field

[0001] The invention belongs to the field of distributed control system data verification, and in particular relates to a distributed control system FBD (Function Block Diagram) component measurement point name verification method and related equipment. Background Art

[0002] In the power industry, the distributed control system (DCS) is the core control system of modern thermal power plants, hydropower stations, nuclear power plants and other power generation facilities. It undertakes the important task of comprehensive monitoring and automatic control of various units and equipment. The DCS system integrates multiple functional blocks to achieve precise control of each production link of the power plant. In these functional blocks, the measurement point reference is the key link between the field sensors and actuators and the control system. In order to ensure that the function block can accurately obtain the real-time data of the field equipment and issue the correct control instructions when necessary, the correct KKS (unified power plant identifier, also known as the measurement point name) must be filled in the measurement point configuration of the function block. The KKS system is an internationally standardized power plant identification system. It realizes the standardization and normalization of power plant information by uniformly encoding power plant equipment, systems, components, etc. In the DCS configuration process, the correct reference of the KKS measurement point is crucial to ensure the correctness and stability of the system control logic.

[0003] However, in actual operation, due to human factors or system complexity, users may enter incorrect measurement point names. This error will not only lead to inconsistent data types of the referenced measurement points, but also cause measurement point reference value errors, thus affecting the control effect of the DCS system. During the unit commissioning phase, such errors may increase the commissioning time cost and extend the time it takes for the power plant to be put into commercial operation. More seriously, during the operation of the unit, incorrect measurement point references may cause malfunctions of on-site equipment and even cause safety accidents, posing a serious threat to the safety of power plant equipment and personnel.

[0004] Therefore, how to ensure that KKS measuring points are correctly referenced during the DCS configuration process and avoid abnormal operation of logical configuration due to human errors is a technical problem that needs to be urgently solved in the current field of power industry automation. Summary of the invention

[0005] The object of the present invention is to provide a distributed control system FBD component measurement point name verification method and related equipment to solve the problem that the DCS configuration process may introduce erroneous measurement point names.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: In a first aspect, a method for verifying the name of a FBD component measurement point in a distributed control system comprises the following steps: Obtain the KKS information and function block information of the FBD component, and generate the redundant measurement point name corresponding to the KKS information and the sub-key measurement point name of the current structure variable; Search for the path information of the sub-key measurement point name or the redundant measurement point name of the current structure variable in the KKS hash table. If the path information is repeated, it means that the KKS information already exists, and the verification ends. Otherwise, proceed to the next step; Search for measurement points according to the KKS information, and perform IO measurement point type matching or global variable measurement point type matching. In the global variable measurement point type matching, traverse the sub-key measurement point names and retrieve the corresponding sub-key measurement point information, and compare the sub-key measurement point information with the function block information for verification; After retrieving the corresponding redundant measurement point information according to the redundant measurement point name, verify the redundant measurement point information; Verify the reference situation of the measurement points corresponding to the KKS information to complete the verification of the measurement point names of the FBD component.

[0007] In some embodiments, the step of generating the redundant measurement point name corresponding to the KKS information and the sub-key measurement point name of the current structure variable specifically includes: Check whether there are structure-related fields in the KKS information. If there are structure-related fields, the KKS information represents the measurement point name of the structure primary key. Based on the structure sub-key members and according to the measurement point name of the structure primary key, generate the sub-key measurement point name of the current structure variable; According to the function block information, check whether the function block corresponding to the KKS information is a redundant function block. If it is a redundant function block, generate a redundant measurement point name based on the KKS information.

[0008] In some embodiments, the step of searching for measurement points according to the KKS information and performing IO measurement point type matching or global variable measurement point type matching specifically includes: When the measurement point found according to the KKS information is an IO measurement point, compare the function block information with the IO measurement point information, and judge whether the device number, data type, and input / output type of the function block information and the IO measurement point information are consistent. If they are consistent, the IO measurement point type matching is successful. Otherwise, the matching fails and an error prompt message is output; When the measurement point found according to the KKS information is a global variable measurement point, compare the function block information with the global variable measurement point information, and judge whether the device number, data type, and input / output type of the function block information and the global variable measurement point information are consistent. If they are consistent, the IO measurement point type matching is successful. Otherwise, the matching fails and an error prompt message is output.

[0009] In some embodiments, the following steps are further included: After determining that the function block implements cross-device reference according to the function block information, match the device numbers of the global variable measurement points and the function block. If the device numbers of the global variable measurement points and the function block are the same, the matching is successful; otherwise, the matching fails and an error prompt message is output.

[0010] In some embodiments, the step of verifying the redundant measurement point information after retrieving the corresponding redundant measurement point information according to the redundant measurement point name specifically includes: Retrieve the redundant measurement point name in the measurement point library of the current device and cross-devices to obtain the matching redundant measurement point information. Compare the redundant measurement point information with the function block information to determine whether the device numbers, data types, and input / output types of the function block information and the redundant measurement point information are the same. If they are the same, the redundant measurement point information is successfully matched; if not, the redundant measurement point information is mismatched and an error prompt message is output.

[0011] In some embodiments, the step of completing the verification of the measurement point names of FBD components after verifying the reference situation of the measurement points corresponding to the KKS information specifically includes: If the current function block is a function block associated with a structured variable or an output symbol block, traverse the reference information list of all function blocks in the current device's POU page, and compare the KKS information that is the same as the current measurement point in the reference information list, the corresponding reference information and the information of the current function block. If the reference information and the information of the current function block are exactly the same, the current measurement point of the current function block is correctly referenced; otherwise, the current measurement point is incorrectly referenced by other function blocks and an error prompt message is output; Traverse the current device's reference failure information list. If there is KKS information in the reference failure information list that is the same as the current measurement point, an error prompt message is output.

[0012] In some embodiments, after completing the verification of the measurement point names of FBD components, refresh the measurement point information in the function block.

[0013] In a second aspect, a system for verifying the measurement point names of FBD components in a distributed control system includes: A measurement point name generation module, configured to obtain the KKS information and function block information of the FBD component, and generate a redundant measurement point name corresponding to the KKS information and a sub-key measurement point name of the current structured variable; A path information verification module, configured to search for the path information of the sub-key measurement point name or the redundant measurement point name of the current structured variable in the KKS hash table. If the path information is repeated, it means that the KKS information already exists, and the verification ends; otherwise, the next step is performed; The measuring point type matching module is used to find the measuring points according to the KKS information, and perform IO measuring point type matching or global variable measuring point type matching. In the global variable measuring point type matching, traverse the sub-key measuring point names and retrieve the corresponding sub-key measuring point information, and compare the sub-key measuring point information with the function block information for verification; The redundant measuring point verification module is used to retrieve the corresponding redundant measuring point information according to the redundant measuring point name, and then verify the redundant measuring point information; The reference situation verification module is used to verify the reference situation of the measuring points corresponding to the KKS information, and complete the verification of the measuring point names of FBD components.

[0014] In a third aspect, an electronic device includes a memory, a processor, and a computer program stored in the memory and executable in the processor. When the processor executes the computer program, the steps of the method for verifying the measuring point names of FBD components in a distributed control system are implemented.

[0015] In a fourth aspect, a computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the steps of the method for verifying the measuring point names of FBD components in a distributed control system are implemented.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a method for verifying the measuring point names of FBD components in a distributed control system. By searching for the measuring point name path information in the KKS hash table, it can quickly determine whether the KKS information already exists, avoiding repeated verification and improving the verification efficiency. In addition, detailed type matching and verification are performed on IO measuring points, global variable measuring points, and redundant measuring points to ensure the accuracy and consistency of the measuring point information. It avoids the situation where incorrect measuring point names may be introduced during the DCS configuration process.

[0017] Furthermore, the present invention considers the redundancy and cross-device reference situation of function blocks during the verification process, which helps to promptly discover and correct potential errors, enhancing the reliability and stability of the system.

[0018] Furthermore, the present invention can ensure that the measuring points are correctly referenced by verifying the reference situation of the measuring points, avoiding system failures caused by incorrect references. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, and the described content is intended to explain the present invention rather than to limit it.

[0021] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present invention are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or are inherent to these processes, methods, systems, products or apparatus.

[0022] like Figure 1 and Figure 2 As shown, this embodiment provides a method for verifying the name of a FBD component measurement point in a distributed control system, comprising the following steps: Step 1: When the user triggers the measurement point name input action, obtain the KKS information entered by the user in the FBD measurement point name, and at the same time obtain the function block information (including the device number where the function block is located, Pou number, function block instance name, function block type name).

[0023] Step 2: In the current project, retrieve the corresponding device according to the device number in the obtained function block information.

[0024] Step 3: Determine whether there are structure-related fields in KKS. If there are structure-related fields, it means that the current function block is associated with a structure variable. The current KKS represents the measurement point name of the structure's primary key. Based on the measurement point name of the structure's primary key and the structure's sub-key members, generate and cache the sub-key measurement point name of the current structure variable.

[0025] Step 4: Determine whether the function block that references the current KKS is a redundant function block. If it is a redundant function block, generate the corresponding redundant measurement point name according to the KKS and cache it.

[0026] Step 5: Search the path information (device number, page number, node number, branch number, board number, channel number) of the measurement point corresponding to the KKS in the KKS information that has been stored in the library (stored in the KKS hash table of the entire station, or the KKS hash table under the device). If the newly added KKS has not been stored in the library, it is necessary to re-read the KKS information of the IO measurement point and the global variable measurement point, perform the storage operation, and then search for the path information of the measurement point corresponding to the KKS, and start the verification process according to the path information.

[0027] Step 6: According to the search result in Step 5, if the KKS information appears repeatedly, prompt the user that the currently filled KKS already exists and end the verification process.

[0028] Step 7: If the KKS information is not repeated, verify whether the function block type matches the types of the matched IO measurement points and global variable measurement points.

[0029] Step 8: If the measurement point found according to the KKS information is an IO measurement point, perform IO measurement point type matching (compare the function block information in Step 1 with the IO measurement point information). The matching content includes: whether the device numbers are the same, whether the data types are the same, and whether the input / output types are the same. If the measurement point type matching is successful, generate new matching information, which includes: device number, POU number, node number, branch number, board card number, channel number, channel KKS, and channel description information.

[0030] Step 9: If the measurement point found according to the KKS information is a global variable measurement point, perform global variable point matching (compare the function block information in Step 1 with the global variable measurement point information). The matching content includes: whether the device numbers are the same, whether the data types are the same, and whether the input / output types are the same. If the current function block type needs to implement cross-device reference, verify the device numbers of the measurement point and the device where the function block is located. Only NAI function blocks and NDI function blocks will perform cross-device reference. Therefore, it is necessary to match the device numbers of the NAI function blocks and NDI function blocks with the device numbers of the referenced measurement points to verify whether they are the same.

[0031] Step 10: Process the global variable structure body. The KKS of the structure body sub-key is formed by concatenating the main key KKS and the sub-key name. Traverse the measurement point names of the sub-keys generated in Step 3, and in the measurement point library of the current device, retrieve the corresponding sub-key measurement point information according to the sub-key measurement point names, and record the matched sub-key measurement point information.

[0032] Step 11: According to the global variable matching information verification process in Step 9, perform corresponding verification on all sub-key measurement point information of the structure variables matched in Step 10, that is, compare all sub-key measurement point information with the function block information to determine whether the device numbers are the same, whether the data types are the same, and whether the input / output types are the same.

[0033] Step 12: If the current function block is a redundant function block (REDHAI, REDHNI, REDHDI, etc.), retrieve in the measurement point libraries of this device and across devices according to the redundant measurement point names generated in Step 4, and record the matching measurement point information. According to the processes of Step 8 and Step 9, verify the measurement point information and give an error prompt message, that is, compare the redundant measurement point information with the function block information to determine whether the device numbers, data types, and input / output types of the function block information and the redundant measurement point information are consistent. If they are consistent, the redundant measurement point information is successfully matched; if not, the redundant measurement point information fails to match and an error prompt message is output.

[0034] Step 13: If the current symbol block is an output symbol block (HAO, HDO, HNO, or a function block associated with a structured variable), it is necessary to verify whether the measurement point corresponding to the current KKS is referenced by other function blocks to ensure the singularity of the source data of the output measurement point.

[0035] The verification process of Step 13 is as follows: Obtain the reference information list of all function blocks in the current POU page under the current device (referring to the reverse reference information of the measurement points to the function blocks in the current POU page, and each item contains information such as the device number, POU number, function block class type, and function block instance name of the function block associated with the measurement point). Traverse the reference information list. If the KKS in the list item is the same as the KKS of the current measurement point, compare and verify the device number, POU number, function block type, and function block instance name in the reference information with the current function block. If they are exactly the same, it means that the measurement point reference of the current output function block is correct; otherwise, it means that the measurement point of the current output function block is simultaneously referenced by other measurement points, and the data source of the measurement point is not singular, and a prompt message needs to be given to the user.

[0036] Step 15: Check whether there is a failed reference to the current KKS. Traverse the list of failed reference information under the current device. If the KKS contained in the reference information list item is the same as the current KKS, it means that there is at least one failed reference to the current KKS, and an error should be prompted at this time.

[0037] After the above KKS code verification is completed, it is necessary to refresh the reference information of the measurement points in the function block. The refresh process of the measurement point information is as follows: Step 16.1: Obtain the POU page data in the memory; Step 16.2: Determine whether the matching measurement point information is legal (including information such as the length of the measurement point information, the device number and page number where the measurement point is located, the measurement point name, and the measurement point type).

[0038] Step 16.3: Function block dialog parameter refresh process: Traverse all attributes in the function block parameters, search for the attributes according to the attribute names, obtain the attribute values related to the measurement points from the matched measurement point information, and refresh the measurement point attribute values to the corresponding parameter attributes.

[0039] Step 16.4: For the online state, in addition to saving the refreshed measurement point information to the function block parameter attributes according to Step 3, it is also necessary to perform online value setting for the modified parameters.

[0040] For the method for verifying the measurement point names of FBD components in a distributed control system provided in this embodiment, after the user fills in the KKS information, the configuration tool automatically starts the background verification thread. For the measurement points within this device, retrieve information such as the page number, channel number, and measurement point name of the measurement points under this device. For the measurement points referenced across devices, first load the cross-device measurement point library. After the loading is completed, retrieve the corresponding measurement points in the cross-device measurement point library for verification. After passing the measurement point verification, the correctness of the user's configuration design is ensured, error prompt information can be given to the user in a timely manner, and the abnormal operation of the logic configuration caused by human errors is avoided, which harms the debugging and operation of on-site equipment.

[0041] This method provides an automated safety verification process for the user's configuration process, avoiding the cumbersome manual verification of measurement point names, and can largely avoid configuration errors caused by human errors, avoid equipment damage during the debugging and operation of on-site units, ensure the safety of on-site personnel and equipment, and has practical engineering application value.

Otherwise, proceed to the next step; A measurement point type matching module, configured to search for measurement points according to the KKS information, and perform IO measurement point type matching or global variable measurement point type matching.
