Method and system for gathering, collecting and processing cross-regional data of digital system of transformer substation

The invention discloses a transformer substation digital system cross-regional data aggregation, acquisition and processing method and system. The method comprises the following steps: constructing a data acquisition engine; constructing a data resource pool, carrying out data processing, and carrying out unified storage management on the data; a unified data access interface is constructed, request interface input parameter data and callback interface return parameter data contained in interface interaction data both adopt a JSON format character string mode, and permission verification is performed during interaction; according to different data types and function types, four data interaction modes of data query, data subscription (WebSocket, message queue mode) and data reverse pushing are provided. According to the method, data collection is taken as a key point, a plant-station-level data base is formed, a safe and reliable standardized data calling interface is provided, and the data interaction efficie
