Smart home remote control system based on telephone network and control method thereof

Abstract

The invention discloses a smart home remote control system based on a telephone network. The system comprises a ringing detection module and a DTMF dual-audio coding and decoding module, which are respectively connected in parallel with two ends of a household telephone. The output terminal of the ringing detection module is connected with a main controller; a signal sending part and a signal receiving part of the DTMF dual-audio encoding and decoding module are connected with the main controller; the main controller is connected with the input terminal of an analog off-hook and on-hook module, and the analog off-hook and on-hook module is connected with a telephone in series to realize on-off control of a circuit; the main controller is further connected with a voice prompt module, the voice prompt module is connected with a power amplification circuit, the power amplification circuit is connected to a telephone line in parallel, and the voice prompt module prompts a user to operate the controller; a clock module in the main controller is connected with a display module; and a control pin on the main controller is connected with an electric appliance and is used for controlling the on-off and state of the electric appliance.
