[0033] In order to make the objectives, technical solutions and advantages of this application clearer, the following further details this application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0034] In the description of this application: Unless otherwise specified, "a plurality of" means two or more. Terms such as "first", "second", "third", etc. in this application are intended to distinguish the objects being referred to and do not have special significance in terms of technical connotations (for example, they should not be understood as emphasizing importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0035] In one embodiment, referring to Figure 1 and Figure 2 , a method for creating an electronic ledger of standard sub-devices is provided. The method includes:

[0036] Recording device components with the same structure and function on the same device drawing as the standard sub-devices of the same device, and establishing a ledger template for the standard sub-devices and a distribution map of the actual positions of the sub-devices according to the user's selection and input information; the ledger template records the current general information of the standard sub-devices, and the distribution map of the actual positions of the sub-devices presents the actual positions of all standard sub-devices;

[0037] In response to a user's viewing instruction for the ledger of the sub-device at the first actual position, calling the ledger template of the standard sub-device, generating a virtual ledger for the first actual position, and providing the user with the current general information of the standard sub-devices recorded in the ledger template;

[0038] In response to a user's modification request instruction for the ledger of the sub-device at the second actual position, calling the ledger template of the standard sub-device, generating an actual ledger for the second actual position; the initial information of the actual ledger is the current general information of the standard sub-devices recorded in the ledger template, and after the user modifies it, the content modified by the user is saved.

[0039] In this embodiment, if the structures and functions of the components on the equipment drawings are the same, they are recorded as standard sub-equipments under the same equipment. The user can create a ledger template for these standard sub-equipments and a distribution map of the actual positions of the sub-equipments according to the selected and input information. The ledger template records the general information of the standard sub-equipments (such as model, specification, etc.), while the distribution map of the actual positions of the sub-equipments shows the specific positions of all standard sub-equipments in the entire equipment.

[0040] Reference Figure 2 , Figure 2 In [reference], the "equipment ledger" part is an electronic ledger, and the sub-equipment drawings correspond to the distribution map of the actual positions of the sub-equipments. In the equipment ledger part, referring to the "sub-equipment" column, where "Lower Bin Low Pass (Standard)" is the ledger template of the standard sub-equipment, and "Lower Bin at the 001st Screen from the Left" is the virtual ledger of the first actual position ("the 001st screen from the left") of the "Lower Bin Low Pass (Standard)" ledger template. At this time, the information presented by this virtual ledger is the information recorded in the ledger template; "Lower Bin at the 003rd Screen from the Left" is the actual ledger of the second actual position ("the 003rd screen from the left") of the "Lower Bin Low Pass (Standard)" ledger template, and the information shown on the right side of the "sub-equipment" column is the specific ledger content under this actual ledger, that is, the content modified by the user and saved after the user modifies the ledger template.

[0041] Among them, the virtual ledger of the first position can also refer to Figure 9 , Figure 9 which is the virtual ledger at a specific position ("the 194th screen from the left"), and it is also the content information shown by the "Lower Bin Low Pass (Standard)" ledger template. Comparing Figure 2 and Figure 9 it can be seen that Figure 2 the content of "Unit Number is 5" in [reference] is the specific added content of "Lower Bin at the 003rd Screen from the Left", which is the content modified by the user and saved after the user modifies the ledger template.

[0042] Reference Figures 3 - 9 shows the process of creating the electronic ledger of the standard sub-equipment in sequence. In Figure 3 , by selecting the equipment ledger to which the sub-equipment template wants to be added, select whether the added sub-equipment is a "standard sub-equipment" or an "ordinary sub-equipment"; Figure 4 then names the added "standard sub-equipment": Lower Bin Low Pass; Figure 5 is to input the number of virtual sub-equipments for the standard sub-equipment named "Lower Bin Low Pass". In this embodiment, the number of this virtual sub-equipment is 196. After input, the creation of the virtual sub-equipment can be completed. Referring to Figure 6 , due to the large number, the accompanying drawings in the specification cannot show them all one by one. Some virtual sub-equipments are referred to Figure 6; Except for virtual sub-devices, for ease of use, it is also necessary to input the drawings of sub-devices, that is, the actual location distribution map of sub-devices, for reference Figure 7 ; So far, the creation of device templates and virtual account books for standard sub-devices has not been completed, for reference Figure 8 , Figure 8 To edit the device template, input the "sequence number" of "unit number": 3, "category": G, "column number": 1, and "row number": 1 in sequence; "unit name": pipe; and information such as "material", "pipe diameter", and "wall thickness"; through Figure 8 By editing the device template, the editing of multiple virtual account book information can be completed. For specific reference Figure 9 , when the user wants to view the account book information of a specific location ("the 194th screen from the left"), since the sub-device at "the 194th screen from the left" has not been repaired at this time, the account book does not need to be edited, and the displayed information is still its initial state, that is, the state of the account book template.

[0043] When the user wants to view the sub-device account book of a specific location (i.e., the first actual location), the system will call the corresponding standard sub-device account book template and generate a virtual account book based on this template. This virtual account book reflects the current general information of the standard sub-device for the user to view. The virtual account book refers to a temporary view generated according to the template, rather than a modification of the actual data. For reference Figure 9 , Figure 9 For viewing the schematic diagram of the virtual account book of the sub-device at a specific location.

[0044] If the user hopes to modify the sub-device account book of another specific location (i.e., the second actual location), the system also first calls the account book template of the standard sub-device and generates an actual account book based on this. The initial state of the actual account book is a copy of the general information of the standard sub-device recorded in the account book template. Once the user completes the modification and saves it, these modifications will be recorded and become the real account book data of the sub-device at this actual location. This means that for any sub-device that requires personalized adjustment, its specific settings or changes can be saved without changing the global template. For reference Figure 13 , when it is necessary to modify the actual account book, Figure 13 Just edit the displayed content, which will not affect the account book template and other virtual account books.

[0045] In this embodiment, the above-mentioned first actual location and second actual location are respectively used to represent a certain actual location in the two situations of viewing and modifying operations, rather than a special limitation on the actual location of the sub-device; the sub-device at the first actual location can be any sub-device, and the sub-device at the second actual location can also be any sub-device. The sub-device at the second actual location can be the same as or different from the sub-device at the first actual location.

[0046] In this embodiment, it is assumed that there are 100 sub-devices with the same structure and function and manufactured using the same drawing. In fact, it is not necessary to establish 100 account books at the beginning. Instead, only one virtual account book needs to be established as a template. Only when it is necessary to view or operate the account book of a sub-device at a specific location, the virtual account book of that location will be generated. Furthermore, only when repairing or modifying a sub-device will the account book of the actual location be formed.

[0047] Based on further analysis and research of the problems in the prior art, this application realizes that if the functions of hundreds or thousands of components with the same structure are all established as actual equipment account books, the number of account books will be extremely large and the usage efficiency will be very low. If only some local positions are accounted for according to experience, there will be no available account books when repairs and modifications are made to other positions. This application names the equipment components with the same structure and function as the standard sub-devices of the equipment, establishes an account book template for the standard sub-devices, and attaches a distribution map of the actual positions of the sub-devices at all actual positions of the equipment. When viewing the account book of a sub-device at a certain position of the equipment, the virtual account book of the sub-device at that position is generated by calling the account book template. When modifying the operation of a sub-device account book, the account book of the actual position of the sub-device is formed. In this way, it not only solves the problem that the account books at all positions can be operated, but also does not form actual account book content without operation.

[0048] In one embodiment, when the user views and modifies the sub-device account book, the human-computer interaction interface simultaneously displays the general table of the equipment electronic account book and the distribution map of the actual positions of the sub-devices.

[0049] In this embodiment, the human-computer interaction interface simultaneously displays the general table of the directory tree path of the equipment electronic account book and the actual position map where the sub-devices are located.

[0050] In one embodiment, the distribution map of the actual positions of the sub-devices is displayed side by side with the actual account book or the virtual account book. When it is necessary to operate the standard sub-device at the actual position, select the standard sub-device in the distribution map of the actual positions of the sub-devices, and the creation of the virtual account book of the standard sub-device can be completed.

[0051] In this embodiment, refer to Figure 2 , Figure 2 is a schematic diagram of the standard sub-device electronic account book created by using the method provided in the application embodiment. In Figure 2In it, the actual position distribution map of the sub-devices is located on the right side of the actual position ledger or the virtual ledger, and is displayed side by side with it. When the user needs to operate on the standard sub-devices at the actual positions, by clicking on the actual position distribution map of the sub-devices on the right side, a virtual ledger corresponding to the clicked standard sub-device can be created. In this embodiment, the actual position distribution map of the sub-devices can also be located above, below, or to the left of the ledger list. This application does not make specific limitations on the positional relationship between the actual position distribution map of the sub-devices and the ledger list.

[0052] In one embodiment, a numbered association is established between the general ledger of the device electronic ledger and the actual position distribution map of the sub-devices, and the way of establishing the numbered association is pre-automatic numbered association.

[0053] In this embodiment, the general table of the directory tree path of the electronic ledger has established a numbered association with the actual position distribution map of the sub-devices when it is created. Therefore, whether it is a virtual ledger or an actual ledger, a numbered association has been established with the actual position distribution map of the sub-devices; the general ledger of the electronic ledger includes both the already created actual ledger and the standard sub-devices that have established a numbered association with the actual position distribution map of the sub-devices and have not yet created virtual or actual ledgers or have already created virtual ledgers.

[0054] The system has established a close connection between the actual position distribution map of the sub-devices and the ledger by means of pre-automatic numbered association when creating the general table of the directory tree path of the electronic ledger. In the initialization stage, the system will automatically generate a unique number for the position of each standard sub-device and establish an association with the actual position distribution map of the sub-devices. This number is generated based on a preset rule to ensure logic and uniqueness. When creating the general table of the directory tree path of the electronic ledger, each item in this general table (whether it is a virtual ledger or an actual ledger) has been assigned a corresponding number, and these numbers are directly associated with the specific positions on the actual position distribution map of the sub-devices.

[0055] Reference Figure 5 , in the general ledger of the electronic ledger, it includes: (1) The already created actual ledger: the content that has been modified and saved by the user according to the sub-devices at a specific position. (2) The virtual or actual ledger that has not been created yet: Although there are no specific ledger records yet, the positions of these standard sub-devices have been listed in the general table and there are corresponding numbered associations. (3) The standard sub-devices with already created virtual ledgers: These are temporary views generated based on the ledger template and waiting for further personalized modification.

[0056] In this embodiment, by establishing a numbering association with the actual location distribution map of the sub-devices, it is ensured that all ledger information (whether virtual or actual) can be accurately associated with the corresponding sub-device locations, avoiding data confusion or loss. Whether the user is viewing the virtual ledger or modifying the actual ledger, they can quickly locate the actual location of the sub-device through the number, simplifying the operation process. The numbering association makes the management of a large number of sub-devices and their ledgers simpler and more efficient, especially when performing batch operations or updating maintenance records.

[0057] In one embodiment, in the general ledger summary of the device electronic ledger, the presentation forms or identifiers of the actual ledger and the virtual ledger are different.

[0058] In this embodiment, the virtual ledger and the actual ledger can be distinguished by color or gray scale. Refer to Figure 1 , in the ledger list, the standard sub-devices with gray names correspond to the created virtual ledgers, and those with black names are the actual location ledgers.

[0059] In one embodiment, the ledger templates of the standard sub-devices, the actual location distribution map of the sub-devices, and the actual ledgers are all stored in the local database and the system database.

[0060] In one embodiment, the actual ledger of the second actual location is stored in the local database and submitted for approval. After the approval is passed, the actual ledger data in the system database is updated.

[0061] In this embodiment, the local database serves as a temporary storage. By performing preliminary information entry and ledger management in the local database, direct operations on the system database can be avoided, thus ensuring the independence and security of the approval process. Before submitting for approval, the ledger information can be checked and modified multiple times in the local database to ensure data accuracy and consistency. Once the approval is passed, the verified data is updated to the system database, which can reduce the risk of data errors and inconsistencies. Directly entering and modifying a large amount of data in the system database may have a negative impact on system performance. By performing these operations in the local database and updating them to the system database in batches or gradually, the system burden can be reduced, and the stability and reliability of the system can be improved.

[0062] In one embodiment, when the standard sub-device is updated, by updating the general information in the ledger template of the standard sub-device, the virtual ledger is updated, and the actual ledger of the saved specific location remains unchanged.

[0063] In this embodiment, when a standard sub-device needs to be updated, the system will first update the general information in its ledger template. This general information includes, but is not limited to, model, specifications, maintenance cycle, etc., which are attributes common to all sub-devices of the same type. The updated standard sub-device ledger template will be automatically applied to the virtual ledger that has not been specifically instantiated into an actual location ledger. Any newly generated or viewed virtual ledger will be based on the latest version of the template and reflect the latest standard information.

[0064] For those actual ledgers that have been personalized and saved according to specific actual locations, they will not be automatically changed due to the update of the standard sub-devices. These actual ledgers retain the content modified by the user before, ensuring the stability and consistency of the records for each specific location. Protect the formed actual ledgers to avoid the loss or confusion of historical data caused by the global template update.

[0065] In one embodiment, by updating the actual location distribution map of the sub-devices, the overall update of the sub-devices at individual locations in the device electronic ledger is achieved.

[0066] In this embodiment, by updating the standard sub-device location map (adding and deleting), the overall addition and deletion of sub-devices at individual locations in the device electronic ledger are achieved. The actual location distribution map of the sub-devices shows the specific locations of all standard sub-devices in the entire device or facility. It is not only a visualization tool but also serves as the basis for managing and operating these sub-devices. The distribution map establishes a numbered association with the ledger information of each sub-device, ensuring that each sub-device at each location has a clear record and identification.

[0067] The user can select a specific location or area to be updated through the actual location distribution map of the sub-devices. This selection can be a single sub-device, a group of adjacent sub-devices, or even all sub-devices within an entire partition. Once the location or area to be updated is selected, the user can perform a batch update operation on the selected sub-devices, including updating general information (such as model, specifications, etc.), maintenance status, location adjustment, etc.

[0068] General information related to the sub-devices can be updated, such as the latest technical parameters, manufacturer information, etc. Update the maintenance records, operating status, inspection results, etc. of the sub-devices to ensure that the ledger information is consistent with the actual situation. If a sub-device has physically moved or been reinstalled, its location can be directly adjusted on the distribution map and synchronized to the corresponding ledger record.

[0069] In one embodiment, referring to Appendix Figures 10 - 12 , when the same operation is performed on the ledgers of sub-devices at multiple actual locations in the standard sub-devices, by batch-selecting the sub-device locations to be operated on in the standard sub-device list and operating on the general information of the standard sub-devices, the batch operation on multiple sub-devices is achieved.

[0070] In this embodiment, the user can intuitively batch-select the positions of multiple sub-devices that need to perform the same operation through the standard sub-device list, refer to Figure 10 ; in Figure 10 , since it is necessary to batch-operate on 3, 4, 5, 6, and 7 in the sub-device serial numbers, so in the standard sub-device list of Figure 10 , just batch-select these devices. Based on the selected positions, the user can uniformly modify the general information of these sub-devices, refer to Figure 11 , Figure 11 Schematic diagram of modifying or performing other operations on the units of the standard sub-devices after selecting specific positions. Figure 12 Is the schematic diagram of the actual sub-devices formed after completing the batch operation.

[0071] Intuitively selecting and batch-updating sub-devices through the distribution map simplifies the user's operation process and improves work efficiency. After the batch operation is completed, the user can immediately see the change effect, enhancing the responsiveness and transparency of the system. The user can flexibly select batch operations according to needs.

[0072] In one embodiment, the standard sub-devices are specifically low-temperature superheater, platen superheater, final-stage superheater, low-temperature reheater, platen reheater, high-temperature reheater, or economizer.

[0073] In one embodiment, a computer program product is also provided, including computer programs / instructions, and when the computer programs / instructions are executed by a processor, the steps of the method in the above embodiment are implemented.

[0074] The technical features of the above embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
