Method and system for identifying electric equipment on line

The invention discloses a method and a system for identifying electric equipment on line. The method comprises the following steps: step 1, acquiring key data parameters of the on-line electric equipment; 2, carrying out data analysis processing on the collected key data parameters, comparing the data parameters with data parameters pre-stored in a database to determine an operation data portrait corresponding to the data parameters or prompting a user through information to mark an equipment name, and storing the equipment name to form core characteristics of the electric equipment; 3, sending the determined operation data portrait or prompt information to the mobile terminal, and displaying or marking the equipment name by the mobile terminal; wherein in the step 1, the key data parameters comprise current, voltage, resistance, harmonic waves and power data signals. According to the invention, the data of the electric equipment is collected and analyzed, and the type of the electric equipment is identified,
