Abstract

The invention relates to an intelligent home appliance control system based on speech identification technology and a wireless sensing network. The intelligent home appliance control system is characterized in that the system comprises a speech identification module and a wireless transmission module based on a Zigbee network; the speech identification module is provided with wireless audio input equipment connected with a PC computer and a speech identification unit; audio input data of a user is received through the audio input equipment, is processed through the speech identification unit and is converted into a corresponding control instruction; the wireless transmission module adopts a Zigbee communication protocol and comprises a serial port communication circuit, a network coordinator, each sub-node and a working state conversion circuit; the control instruction from the user is subjected to data processing through the serial port communication circuit and is used for controlling the corresponding working state of each sub-node; and data information of each sub-node in the network is displayed in the PC computer. The intelligent home appliance control system has safe and reliable operation, convenient installation, simple and convenient use and low power consumption of the system and realizes the controlling intelligence of home appliances.

Description

technical field [0001] The invention relates to a home appliance control system, more specifically an intelligent home appliance control system. Background technique [0002] At present, conventional control methods for household appliances are mainly realized through manual operation, and users control the on and off of the household appliances through switches installed at different positions. However, for some handicapped elderly and paralyzed patients and some special occasions where manual operation is inconvenient, this control method is inconvenient or even impossible to use. On the other hand, the conventional control method of household appliances requires separate wiring for switches with different functions. Complex wiring methods and the use of a large number of switches are the main factors that easily lead to accidents, thereby increasing family safety hazards. [0003] With the continuous maturity of speech recognition technology, speech recognition is gradua...
