Abstract

The invention provides a smart home voice control system based on Bluetooth transmission, which is used for realizing voice control between a mobile phone terminal and a smart home electrical appliance. Because a mobile terminal adopts a Bluetooth transmission technology, the mobile terminal is more suitable for a local area network (LAN) in the smart home, thus greatly prolonging the distance of the voice control; and noises in the voice transmitted by the Bluetooth can be extremely eliminated from a pronunciation end, thus a transmitted voice command is more easy to identify and analyze. The system comprises a smart mobile phone terminal and a central control device, wherein the smart mobile terminal comprises a Bluetooth device and a voice input device, and is used for voice collection and Bluetooth transmission of a front end; and the central control device comprises a Bluetooth device, and is used for receiving voice data sent by the smart mobile terminal via the Bluetooth, analyzing the voice data, and sending target control signals to a controller end. A user can control the home electrical appliance by inputting a voice command in the smart mobile terminal, thus realizing a function that the mobile terminal is used to control the home electrical appliance in a short distance, and reaching the purpose of home intelligentization.

Description

technical field [0001] The invention relates to the technical field of digital home smart home, in particular to a smart home voice control system based on bluetooth transmission.
