New energy network data access system based on trust metric value

The invention provides a new energy network data access system based on a trust metric value, which is applied to the field of data access systems. The new energy network data access system comprises a client layer, a background service layer, a gateway layer, a background service layer and a local server, the background service layer comprises an identity authentication module, a credibility evaluation module, an access channel distribution module and a log acquisition module; the identity authentication module is connected with an identity database, a plurality of identity authentication levels are arranged in the identity database, and each identity authentication level is correspondingly provided with a fixed trust metric value, a behavior value, a trust weight value and a trust metric value interval; according to the method, trust metric values can be calculated according to identity evaluation of the access parties, and access requests sent by the access parties with different trust metric values enter
