Problems solved by technology

[0002] The current power data integration scheme mainly uses SOA / Web Service technology to realize the format exchange of heterogeneous power data. The essence of this scheme is to encapsulate the power data to be converted into a SOAP call message as a parameter and send it to the target application. The MIS system for simple services supports better, but there are still deficiencies in the transparent distribution of data processing logic, subscription notification of data change events, etc., which are crucial to improving the rapid response ability of power application systems to data changes of
[0003] There are also some solutions to extend the standard OSGi specification through P2P technology or service-oriented middleware model. Major changes make it difficult to apply the scheme directly to practice, and there are also intrusive problems of distribution logic

Embodiment 1

[0030] Embodiment 1, the metadata of the remote input layer is exported to the target database through the local output layer.

[0031] Publish the remote input layer module instance to the registration center; the local output layer module (Meta2DB) instance queries the registration center to obtain and subscribe to the corresponding metadata; when the metadata changes, it actively calls back the interface of the Meta2DB instance, and the corresponding Meta2DB instance Interceptor modules weave in the required transaction logic.

Embodiment 2

[0032] In Embodiment 2, the metadata is imported from the remote input layer, and after being processed by the instance of the local metadata layer, the metadata is exported to the remote output layer.

[0033] Publish the remote input layer module (Db2Meta) instance and the remote output layer module (Meta2DB) instance to the registry; the local metadata layer module (Metadata) instance queries the registry to obtain the service of the remote Db2Meta instance, and filters the obtained metadata , combination, sorting, etc.; the local metadata layer module (Metadata) instance queries the registration center to obtain the service of the remote Meta2DB instance, and exports the processed metadata to the target database.

Abstract

The invention provides a distribution method of a universal power data platform. OSGi (Open Service Gateway initiative) specifications and WebService technology are taken as the bottom implementation mechanisms of the method; a typical design mode of chain of responsibility is introduced, an interceptor is arranged between a client and a server, and the interceptor is enabled to automatically intercept and forward all remote service calls initiated by the client, and therefore, the programming model of the original OSGi specifications is maintained as much as possible while the platform distribution is realized, and furthermore, a power data integration platform is enabled to have the ability of detecting metadata change and executing corresponding service operations.

Description

technical field [0001] The invention belongs to the field of power system data management, and in particular relates to a distribution method and application of a general power data platform. Background technique [0002] The current power data integration scheme mainly uses SOA / Web Service technology to realize the format exchange of heterogeneous power data. The essence of this scheme is to encapsulate the power data to be converted into a SOAP call message as a parameter and send it to the target application. The MIS system for simple services supports better, but there are still deficiencies in the transparent distribution of data processing logic, subscription notification of data change events, etc., which are crucial to improving the rapid response ability of power application systems to data changes of.
