Cross-network heterogeneous data resource configuration method, device and system

The invention discloses a cross-network heterogeneous data resource configuration method, device and system. The system comprises a client layer, an application layer and a data layer, the client layer is used for generating a data resource configuration request of a user and sending the data resource configuration request in the form of an HTTP (Hyper Text Transport Protocol); the application layer is used for processing a data resource configuration request sent by a client and transmission of electric power data, and performing extraction, format conversion, classification and storage operation on the transmitted electric power data; and the data layer is used for storing the power data of different message types and comprises a plurality of databases with different network isomerism, and each database stores the power data of the corresponding message type. The interconnection service is provided for the Web based on HTTP protocol communication, the unified mode of heterogeneous data is established by usi
