According to the technical scheme provided by the invention, the standing book storage tables corresponding to all the data units are sorted in an ascending order according to the number of the devices in each standing book storage table, so that the standing book storage table with smaller number of devices in the standing book storage table is arranged at a front position. At the moment, the invention can traverse according to the sequence of the standing book storage tables in the standing book sorting result, and sequentially obtain the equipment in each standing book storage table as the target equipment.
Before a power grid equipment panoramic model is obtained through initialization, the method and the device need to obtain the source pasting information corresponding to each target equipment, so that the method and the device can sequentially traverse each equipment as the target equipment according to the standing book sorting result, and place the standing book storage tables with few equipment in front of the standing book sorting result, so that the standing book storage tables with few equipment can be preferentially traversed, the overall data processing amount is reduced, and the number of hung standing book storage tables to be processed is relatively reduced.
Step S130, obtaining corresponding source pasting data of the target device in other standing book storage tables, obtaining a device mapping relation of the target device according to pre-association of the standing book storage tables, and generating a power grid device panoramic model based on the device mapping relations of all the target devices. The method and the device can obtain the source pasting data of each target device in other standing book storage tables, further obtain the source pasting information of the target device in each standing book storage table, and all the source pasting information of each target device can form the source pasting data. According to the method and the device, the device mapping relation of the target device can be obtained according to the pre-association of the standing book storage table, and the panoramic model of the power grid device can be quickly formed.
In a possible embodiment of the present invention, as shown in fig. 3, step S130 includes:
step S1301, determining a target device obtained from the currently traversed ledger storage table, and determining at least one ledger storage table to be screened based on a pre-association relationship of the ledger storage table. According to the method, corresponding target devices are sequentially traversed according to the standing book sorting result, and at least one standing book storage table to be screened is determined according to the pre-association relationship of the standing book storage tables, for example, the currently traversed standing book storage table is a secondary control system, the standing book storage table of the secondary control system is pre-associated with the standing book storage table of the regulation and control cloud platform, and then the standing book storage table of the secondary control system is directly determined to be the standing book storage table to be screened.
Step S1302, acquiring a corresponding target device in the ledger storage table to be screened, and mapping the source posting information corresponding to the same target device in the currently traversed ledger storage table and the ledger storage table to be screened, where the source posting information includes at least one source posting information. The invention can obtain the corresponding target equipment in the standing book storage table to be screened, one target equipment can possibly appear in a plurality of standing book storage tables, and the plurality of standing book storage tables have different information of the same equipment. The posting source information of all the standing book storage tables forms posting source data referred to in the invention.
Step S1303, a power grid equipment panoramic model is initialized, the power grid equipment panoramic model comprises initial preset calling paths of all data units corresponding to each target equipment, the initial preset calling paths comprise a plurality of initial sub-paths, the starting point of each initial sub-path is the power grid equipment panoramic model, and the end point of each initial sub-path is the virtual address of the corresponding data unit. The method and the system can initialize the panoramic model of the power grid equipment, the basis for initializing the panoramic model of the power grid equipment is all target equipment, and the method and the system can obtain the initial preset calling paths of all data units corresponding to each target equipment. It can be understood that the power grid equipment panoramic model may be a starting point of the initial sub-path, that is, the power grid equipment panoramic model may call the initial sub-path, an end point of the initial sub-path is a virtual address of a corresponding data unit, the virtual address is not an actual address, at this time, corresponding information and data are not stored in the virtual address, and data called by the power grid equipment panoramic model when calling data according to the initial sub-path is null.
And step S1304, synchronously modifying all initial preset invoking paths by the power grid equipment panoramic model according to the equipment mapping relation to obtain synchronous invoking paths, so that the end points of part of the initial preset invoking paths are the storage positions of the source pasting information of the corresponding ledger storage table. The power grid equipment panoramic model can synchronously modify all initial preset retrieval paths according to the equipment mapping relationship, for example, a certain target equipment correspondingly retrieves a plurality of initial preset retrieval paths in different ledger storage tables, and a certain ledger storage table has source pasting information of the target equipment, so that the initial preset retrieval paths need to be synchronously modified to obtain the synchronous retrieval paths, and the end points of the initial preset retrieval paths are modified to ensure that the end points of the initial preset retrieval paths are not empty any more, and the end points of the initial preset retrieval paths are storage positions of the source pasting information.
In a possible implementation manner, the performing, by the panoramic model of the power grid device, synchronous modification on all initial preset invoking paths according to the device mapping relationship to obtain synchronous invoking paths, so that a terminal point of a part of the initial preset invoking paths is a storage location of source pasting information of a corresponding ledger storage table specifically includes:
and the power grid equipment panoramic model modifies the end point of the initial sub-path of the part of the initial preset invoking path according to the equipment mapping relation to obtain a synchronous sub-path, and modifies the virtual address of the initial sub-path into a corresponding actual address. It can be understood that each initial preset invoking path may include a plurality of initial sub-paths, and the initial sub-paths for the target device to perform information and data invoking on all the ledger storage tables constitute the initial preset invoking path. According to the technical scheme, when information and data in a certain ledger storage table are changed or the corresponding initial sub-path is required to be capable of calling the information and the data, the end point of the corresponding initial sub-path is modified to obtain the synchronous sub-path, namely the virtual address of the initial sub-path is modified to the corresponding actual address, so that the power grid equipment panoramic model can call the corresponding information and data according to the synchronous sub-path.
And adding first labels to all the synchronous sub-paths, adding second labels to all the initial sub-paths, and generating the synchronous calling path of the target equipment according to all the initial sub-paths and the synchronous sub-paths corresponding to each target equipment. Since one target device may simultaneously correspond to a plurality of synchronization sub-paths and initial sub-paths. If the first label and the second label are not added, when the power grid equipment panoramic model carries out data calling on a certain target equipment, information and data can be called on all synchronous sub-paths and the initial sub-paths to obtain the final information of the synchronous sub-paths, and the information calling efficiency is low at the moment.
After the first label and the second label are added, the power grid equipment panoramic model can only call information and data corresponding to the synchronous sub-paths, and the efficiency of calling the information is high at the moment. In the technical scheme provided by the invention, because the initial sub-paths without information and data calling functions are preset, the corresponding paste source information and paste source data can be quickly obtained only by classifying the sub-paths. Through the steps, the power grid equipment panoramic model is initialized and updated.
Step S140, after the power grid equipment panoramic model at the central station receives the abnormal equipment transmitted by the first type of data unit, the sticking source data of the abnormal equipment in different data units are obtained, and corresponding operation tickets and/or overhaul tickets are generated based on the sticking source data. In the actual working process of the power grid, for example, when a certain transformer is in an open circuit, the intelligent operation and inspection control platform can serve as a first type of data unit and the transformer as abnormal equipment at the moment, so that the problem data unit and the problem platform can serve as the first type of data unit, the panoramic model of the power grid equipment can obtain source pasting data of the transformer in different data units, for example, source pasting data in the control cloud platform, the source pasting data can be times of maintaining the transformer, and the like, and corresponding operation tickets and/or maintenance tickets can be generated according to the source pasting data of the abnormal equipment in the control cloud platform at the moment. The operation ticket can be used for carrying out corresponding operations, such as controlling the transformer power-off process. The service ticket can be the corresponding service, for example, the service of the transformer.

wherein the content of the first and second substances,
in order to allow the number of runs for the CPU,

is the residual rate of the CPU, and the CPU is the CPU residual rate,
in order to use the occupancy rate of the CPU,
in order to cache the number of allowed runs,
in order to buffer the remaining occupancy rate,
the rate of the buffer margin is the rate of the buffer margin,
occupancy is used for the cache.
The smaller number of the CPU allowed number of runs and the cache allowed number of runs is selected as the number of runnable models.
And if the CPU allowed operation number and the cache allowed operation number are respectively larger than the maximum model number, taking the maximum model number as the operable model number.
And carrying out mirror image processing on the power grid equipment panoramic model according to the number of the operable models to obtain the power grid equipment panoramic models with corresponding number. Through the technical scheme, when data processing is carried out through the power grid equipment panoramic model, the power grid equipment panoramic model can be mirrored, so that a large number of power grid equipment panoramic models can be processed in parallel, and the data processing efficiency is improved.
And counting the mapping relations of all the target devices to generate a total mapping set, and decomposing the total mapping set to obtain a plurality of sub-mapping sets with the number of the operable models.
