Method and system for identifying terminal by intelligent electric meter

The invention discloses a method and system for identifying a terminal by an intelligent electric meter. The method includes: by identifying an identification code of a terminal to be identified, establishing a physical connection between an intelligent electric meter and the terminal to be identified; obtaining registration information of the terminal to be identified through the physical connection; and performing information matching on the registration information of the terminal to be identified and prestored terminal registration information, so as to perform identity verification on the terminal to be identified. The system corresponds to the abovementioned method, and includes: a physical connection establishing module, a registration information acquisition module and a registration information matching module. The method and the system for identifying the terminal by the intelligent electric meter can remarkably improve security of a home network and household power utilization, and can enhance security of an access control system at the same time.
