Abstract
The invention relates to the power dispatching automation field, especially to a method for keeping a resource ID unchanged during power dispatching main/standby system full model synchronization. According to the method, a temporary model base is set up in a back-up system and a next distributable resource ID is stored; therefore, if it is needed to distribute a new resource ID, the distribution can be carried out from the source ID backwardly during each model synchronization process, so that repetition with the existing resource ID can be avoided. Meanwhile, before the resource ID distribution, a uniform resource identifier (Uri) access real-time model base is used to obtain the existing resource ID, so that a resource ID will not be distributed again to an existing repeated Uri and thus the resource ID will not be changed, an occurrence of a problem that a same Uri is mapped into different resource IDs in two model synchronization processes can be prevented, and uniqueness of the resource ID can be ensured.

(2) the beginning model is synchronous; Empty the model information in the temporary pattern storehouse earlier; Again from the next allowable resource ID of real-time model library inquiry storage unit, and the next assignable resource ID that will inquire writes the next allowable resource ID storage unit in temporary pattern storehouse.
Through writing down next allowable resource ID; Can make this model synchronizing process if need to distribute new resource ID all to distribute backward from this resource ID; To guarantee that the resource ID before this resource ID can not redistributed, effectively avoid repetition, guarantee the uniqueness of resource ID.
(3), circulation reads main system model resource object, deposit corresponding model information in the temporary pattern storehouse according to request for information: read the model resource object that main system provides one by one, the Uri through this object is to the corresponding resource ID of real-time model library inquiry; If successful inquiring then can write the temporary pattern storehouse with the mapping of this resource object and Uri and resource ID; If the inquiry failure is then applied for next assignable resource ID to the temporary pattern storehouse, the mapping with resource object and Uri and this resource ID writes the temporary pattern storehouse again, and need add up and upgrade next allowable resource ID in the temporary pattern storehouse simultaneously.
The present invention is before Resources allocation ID; Use Uri visit real-time model storehouse earlier; Obtain existing resource ID; The Uri that can guarantee existing repetition can not redistributed resource ID and cause resource ID to change, prevent twice model synchronously in identical Uri be mapped as the problem of different resource ID, also can guarantee not have the resource ID of the up-to-date distribution of Uri of corresponding resource ID can not repeat simultaneously with existing resource ID.Simultaneously, when obtaining resource ID, adopted the mode of batch inquiry, can not come the influence on the runnability the real-time model library tape in visit real-time model storehouse.
(4), after all model resource objects read and finish, the model information in the temporary pattern storehouse is derived and imports the real-time model storehouse, it is synchronous to finish this model.When the real-time model storehouse imports model information, all replace the original model information in the real-time model storehouse, the updating real-time model bank.The model resource object that writes down in the temporary pattern storehouse is compared with the real-time model storehouse, and its corresponding resource ID of resource object that Uri repeats is consistent.
The described model information of above-mentioned steps comprises the Uri and the mapping relations that are equipped with resource ID in the system of model resource object and this resource object.
The invention solves the inconsistent problem of model resource object resource ID when being mapped to resource ID that has repetition Uri in twice model synchronizing process; Compared with prior art; Can effectively avoid need reading under the system fully model information uses respectively be applied in be not written into Uri and resource ID again and shine upon before; The problem that can't normally move; Reduce the physical store various in enormous quantities (like a large amount of resource ID graphic files that record) of record resource ID and need change one time workload again, avoid other directly configuration files of record resource IDs, before revising again, do not causing using the problem that normally to move.
