Data processing method and device applied to intelligent power grid

The embodiment of the invention discloses a data processing method and device applied to an intelligent power grid. A specific embodiment of the method comprises the following steps: receiving query information sent by terminal equipment, the query information comprising query region information and a query time range; determining whether historical data matched with the query information exists in a historical database or not; in response to determining that the historical data matched with the query information does not exist in a historical database, sending acquisition information generated based on the query information to a micro cloud server located in a query area indicated by the query area information, so as to allow the micro cloud server to perform data acquisition through themonitoring equipment, and performing screening processing on data acquired by the monitoring equipment through the proxy server to obtain acquired data; processing the acquired data returned by the proxy server to generate a
