Abstract
The invention discloses a method for data synchronization after distributed application recovery parallelism of an automatic power dispatching system. The method is characterized by comprising the following steps of: 1) circularly detecting whether the local area system application is recovered to a parallel operating condition from a split operating condition by a system operating condition detection module, performing continuous detection if the condition is not met, and starting data synchronization modules after the condition is met; separating the data synchronization modules into a historic sampling data/ alarm recording synchronization module and a manual operating data synchronization module according to different types of data to be synchronized; 2) synchronizing the historic sampling/ alarm recording data stored in the system splitting period to a main system; and 3) synchronizing the operating data in the system splitting period to the main system according to different operating information types by adopting different synchronization methods. The method can effectively avoid the loss of the system application data in the splitting period after system splitting recovery.

Embodiment
Below in conjunction with accompanying drawing the present invention is done further introduction in detail:
Whether system running state detecting module cycle detection one's respective area system applies reverts to the paired running state by the off-the-line running status, and condition does not satisfy then continuation and detects, and condition satisfies back log-on data synchronization module; Data simultaneous module as required data in synchronization type difference be divided into the history samples data alarm record synchronization module, manual operation data simultaneous module: trigger at once behind the system restoration paired running history samples data alarm record synchronization module start; The history samples data alarm record synchronization module obtain the history samples and the warning information data file of local cache, data file is submitted to the document analysis module; The document analysis module is obtained the history samples data message and alarm recorded information during the off-the-line from data file, history samples data message of resolving the back acquisition and alarm recorded information are submitted to main system historical data service module; Main system historical data service module obtains to submit history samples data of preserving during the off-the-line and alarm record to commercial storehouse service module after the request; Commercial storehouse service module then is saved in these information in the database, so far accomplishes the work that off-the-line system history samples data and alarm record data during off-the-line are synchronized to main system.Triggering the manual operation data simultaneous module behind the system restoration paired running at once starts; The manual operation data simultaneous module is obtained the operating data information of buffer memory during the off-the-line of one's respective area from the local storehouse in real time of off-the-line system, with operating data information submit operation information analysis module; The operation information analysis module then obtains the operation information formation through analysis, has comprised information such as action type, operating equipment in the operation information formation, with operation information formation submit operation information synchronization module; The operation information synchronization module is used the different synchronization method according to operation information type different mining, comprises that mainly equipment alarm suppresses to operate synchronously, measurement blockade operation is synchronous, equipment is listed, and operation is synchronous; It is following to carry out illustrated in detail to the method for synchronous of three kinds of dissimilar operations:
1. equipment alarm suppresses the operation method for synchronous
The state of corresponding device in the at first modification system, and with corresponding device state increase alarm holddown, next revises the system operation information table, the alarm that increases corresponding device in the operation information table suppresses operation note.
2. measure and block the operation method for synchronous
The corresponding actual value that measures in the at first modification system, and with corresponding amount measured value state increase blockade blocked styate, next revises the system lock information table, increases the blockade record of corresponding measurement in the table that suppresses information.
3. the equipment operation method for synchronous of listing
At first obtain the type sign board attribute information in the sign board definition list; According to equipment or the state quantity measurement after corresponding device is listed in the sign board attribute information modification system; Next revises system sign board information table, increases in the sign board information table corresponding equipment record of listing.
After everyone operation information synchronization end, then manual operation data simultaneous module finishes.
Accompanying drawing 1 is a kind of typical distributed application schedules automated system allocation plan; In the Distributed Application dispatch automated system; Under the normal condition; Distributed Application (be each zone, as regional A, area B among the figure ..., regional N) through backbone network link to each other (as the network A among the figure, network B ..., network N), use through network remote in each zone and obtain application function that the main system application service realizes the one's respective area.If this time domain A and main system networking are interrupted, system is in subregion off-the-line running status among the then regional A.To be cached to local file or in real time in the storehouse in the data of regional A off-the-line run duration, after network recovery between regional A and the main system is normal, paired running will recover in regional A system, will obtain the main system application service through network remote again at this moment.Zone A recovers behind the paired running at once, and the log-on data synchronization module writes down the history samples data during off-the-line, alarm record, manual operation synchronously to main system; Wherein the method for synchronous for history samples data and alarm record carries out synchronously for the data file of directly obtaining local cache;, carry out synchronously then through behind the off-the-line operation information that reads local banked cache in real time for manual operation synchronization of data method according to the different sample different synchronization method of action type.After accomplishing, zone A system data synchronization module will make the data of whole each area applications of distributed system after recovering side by side, reach in full accord in the generation off-the-line.The assurance system data is complete, and is available.
The foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that form obtained of replacement or equivalent transformation, all drop within protection scope of the present invention.
