The invention relates to a method for reading a parameter system of an electric energy metering device based on an intelligent terminal. The method comprises the steps of calling a GIS system and an aided decision making supporting system by an intelligent terminal user according to a meter contact operation plan which is transmitted by a work order system, and generating an induction current parameter and an induction voltage parameter; obtaining an electric energy meter parameter, a current induction parameter, a voltage induction parameter and client basic information of the metering device by the intelligent terminal user through scanning a barcode of the electric energy metering device by the intelligent terminal, accessing Internet through the intelligent terminal, and accessing a cloud database server by the intelligent terminal user by means of an authenticated account number, thereby realizing data interaction between the parameters of the electric energy metering device and the cloud data server. The method is advantageous in that manpower and meter reading time of the intelligent terminal user are saved in meter reading; electric energy metering device data which are identified by APP software are read through the intelligent terminal; and furthermore the electric energy metering device are uploaded to the cloud database server.
