The specific synchronization method process can refer to the related content of embodiment 2.
Example 2
Based on the same inventive concept as embodiment 1, this embodiment introduces a unified data synchronization method between power grid dispatching automation systems, and with reference to fig. 3, the method includes:
receiving a data synchronization request sent by an application service through a preset synchronization request service interface, wherein the data synchronization request comprises data to be synchronized and a service type corresponding to the data to be synchronized;
generating a unique synchronous request ID aiming at the received data synchronous request, and returning the unique synchronous request ID to the application service through a synchronous request service interface;

the received synchronous data processing result is notified to the unified synchronous service through the network transmission sending service, and corresponding data in a synchronous data sequence to be transmitted are processed through the unified synchronous service;
and, in response to receiving a synchronization result query request sent by an application service, returning the synchronization data processing result to the application service; the synchronization result query request includes the synchronization request ID.
The unified data synchronization method can be suitable for various application services in a power grid dispatching control system, and the covered service types comprise graphic data, model data, operation control data, important alarm data and the like. The data synchronization request can be accompanied by a check code besides the data to be synchronized and the corresponding service type thereof, and is used for validity check during data synchronization processing.
Furthermore, the unified data synchronization method of this embodiment can also implement priority management, timeliness management, target system management, and the like of data to be synchronized, and can be implemented by pre-configuring service data synchronization configuration information, for example, pre-designing service data synchronization configuration information including service type priority information, synchronization target system information corresponding to a service type, data timeliness information, and the like.
When the unified synchronization service generates a synchronization data sequence to be transmitted, the data to be synchronized is written into the synchronization data sequence to be transmitted with the corresponding priority according to the service type priority corresponding to the data to be synchronized, so that a plurality of synchronization data sequences to be transmitted corresponding to different priorities can be obtained. During transmission, sequentially reading data to be synchronized in each synchronous data sequence to be transmitted according to the priority of the service type from top to bottom; and for the read data to be synchronized, acquiring the pre-configured synchronization target system information corresponding to the read data to be synchronized, establishing encryption connection between the network transmission sending service and the network transmission receiving service of the target system, reading the corresponding data from the transmission queue, and then transmitting the data to the network transmission receiving service of the corresponding target system.
When the data to be synchronized is transmitted, an asynchronous transmission mechanism is adopted, the receiving end does not need to wait for the return confirmation of the receiving end, so that the network transmission throughput is improved, the sending rate is limited according to the network capacity quota between systems, and the influence on other services is avoided.
For the data timeliness management, the unified synchronization service carries out timeliness management on corresponding data to be synchronized according to data timeliness pre-configured by service types, and if the data to be synchronized fails, the corresponding data is deleted.
After receiving the data to be synchronized, the network transmission and reception service sends the data to a synchronous data processing service, and the synchronous data processing service can be arranged on an application service side and is used for synchronously processing the data to be synchronized. For the same type of service data, the network transmission receiving service is sent to the synchronous data processing service in a serial mode, and for different types of service data, the network transmission receiving service is sent to each synchronous data processing service in a parallel mode to guarantee the high efficiency of data synchronization.
The synchronous data processing service carries out synchronous data processing on data to be synchronized, and comprises the following steps: checking whether the data to be synchronized is in a preset standard format, wherein the format of the data to be synchronized needs to be agreed by a sender and a receiver of the synchronization service; checking whether the data content to be synchronized is complete; checking whether a data object corresponding to data to be synchronized is a data object in the system; and if all the checks pass, updating the data to be synchronized to a local data object, completing data synchronization, returning the processing result and the synchronization request ID to the network transmission receiving service of the local system, and then forwarding the processing result and the synchronization request ID to the network transmission sending service of the synchronization initiating system, wherein the network transmission sending service of the synchronization initiating system informs the data synchronization processing result to the synchronization data management service of the local unified synchronization service.
For each synchronization operation, the synchronous data processing service can realize the rollback of data by setting a rollback mechanism, backup the data of the previous version during each data synchronization, and restore the data to the data of the historical specified version when rollback is needed.
The synchronization process result may involve: in-sync, complete sync, network interrupt, no processing service found, sync failed, etc. For the normal synchronization situation, the synchronization data processing service can return other important information, such as data version numbers before and after synchronization, besides the synchronization success information.
And the synchronous data management service processes corresponding data according to the data synchronous processing result, and if the synchronous processing result is failure, or the synchronization fails due to network interruption or data processing service can not be found, and the current data is not invalid, the synchronous data management service can execute retransmission processing on the corresponding data.
And for the synchronous processing result returned by the synchronous data processing service, the synchronous data management service adopts a synchronous result queue for management, on one hand, when the business application sends out a synchronous result query request, the corresponding result in the queue is returned to the business application, on the other hand, the number and the retention time of the synchronous processing results in the queue are preset, and when the total number or the retention time is exceeded, the synchronous processing result which is in longer time or is overtime in the queue is deleted.
In order to avoid data mistaken deletion caused by single machine errors, the unified synchronization service stores the data to be synchronized to a plurality of distributed storage nodes in the current system after receiving the data to be synchronized, so that redundant storage management is realized, and the data consistency is maintained among the storage nodes through heartbeat; and after the network transmission sending service informs the unified synchronization service of the received synchronous data processing result, if the synchronous data processing result is correspondingly synchronized, the unified synchronization service also deletes corresponding data of the distributed storage nodes.
The following describes in detail the operation mechanism of the unified synchronization service in the unified data synchronization method according to the present invention, taking the example of synchronizing CIM/G graphics data from the primary scheduling automation system to the standby scheduling automation system in conjunction with fig. 2.
The master and standby power grid dispatching systems are all deployed with unified synchronization service, the graphic synchronization service of the master dispatching automation system calls a data synchronization request interface, the service type corresponding to the data to be synchronized is graphic data, the data is graphic CIM/G content, and the application service calls the synchronization request interface to send the graphic data to be synchronized to the unified synchronization service, so that the synchronization request ID1 returned by the synchronization request service of the unified synchronization service is obtained. And the synchronous data management service checks that the synchronous priority of the graphic data is low priority according to the preset service data synchronous configuration, and stores the data related to the graphic synchronous request into a low-priority transmission queue.
After the network transmission sending service of the main dispatching system is started, encrypted communication connection is established with the network transmission receiving service of the standby dispatching system, and when the graphic data are transmitted, the network transmission sending service of the main dispatching system reads the graphic data from the transmission queue and sends the graphic data to the network transmission receiving service of the standby dispatching system.
After receiving the graphic synchronization data, the network transmission and reception service of the standby scheduling system forwards the data to a graphic synchronization processing service of the standby scheduling system, such as a service data processing service set on an application service side as shown in fig. 2.
The graphic synchronization processing service checks whether the corresponding graphic name and the graphic content in the received synchronous graphic data are in a standard CIM/G format, further checks whether the graphic content description is complete and whether the graphic name belongs to the graphic in the system, and then judges whether the data object is correct. After the check is passed, the original graphic file is backed up, the received graphic content is updated to the latest graphic file, and the synchronization is returned to be successful. If the check fails, return the check error message.
And the transmission receiving service of the standby dispatching system returns the processing result of the graphic synchronous processing service and the synchronous request ID1 to the transmission sending service of the main dispatching system.
The transmission and transmission service of the master system notifies the synchronous data management service of the synchronous request ID and the processing result. And after receiving the synchronization result, the synchronous data management service stores the synchronization result into a synchronization result queue and deletes the synchronous data corresponding to the ID1 from the transmission queue.
And the application service sending the graphic synchronization request in the main scheduling system calls the query interface to query the ID1 synchronization result, so that the graphic is successfully synchronized to the standby scheduling system, and the subsequent operation can be continued.
By utilizing the unified data synchronization method, the two synchronous parties can be synchronized in a single direction and in a two-way direction, and can be synchronized to a single target system or a plurality of target systems.
