The invention discloses a network access method of an intelligent device, the intelligent device and a mobile terminal in the technical field of intelligent devices. The method comprises a mobile phone terminal. The mobile phone terminal is in electrical output connection with a wireless routing module used for releasing a wireless network. The wireless routing module is in electrical output connection with a single-chip microcomputer used for analysis and judgment. The single-chip microcomputer is in electrical input connection with a registration module used for registering an account, a login module used for logging in the account, a comparison module used for comparison and a control module used for control. The single-chip microcomputer is in electrical output connection with an intelligent device, a storage module used for storing information and a prompt module used for sending prompt information. The selected intelligent device is verified through the verification module in thecontrol module. The intelligent device to be connected and bound is compared with the data stored in the comparison module. It is guaranteed that the intelligent device to be connected and bound is not bound, reoperation caused by connection errors is avoided, and operation difficulty is reduced.
