Intelligent household system based on ZigBee and speech recognition

Abstract

The invention provides an intelligent household system based on ZigBee and speech recognition; the intelligent household system comprises an environment information obtaining terminal, a man-machine interaction terminal, a main controller and an execution mechanism; the environment information obtaining terminal comprises ZigBee terminal nodes and an coordinator; the ZigBee terminal nodes are connected with various sensors so as to obtain the environment information, and the environment information is sent to the coordinator through a built ZigBee wireless network; the man-machine interaction terminal comprises a speech recognition module and an LCD; the speech recognition module is used for obtaining user speech information and identifying the speech information; the LCD sends the environment information and safety information to the user; the main controller refers to an ARM chip built system, is used for receiving and processing the environment information and the speech recognition information, thus driving execution mechanism corresponding equipment. The intelligent household system can use speech to control household electrical appliance equipment, can collect household environment information and send alarms on abnormal information, thus improving household life convenience and security.

Description

technical field [0001] The invention belongs to the field of smart home and embedded applications, in particular to a smart home system based on ZigBee and voice recognition. Background technique [0002] As one of the main places for people's daily activities, houses are closely related to people's physical and mental health. With the rapid development of science and technology, people have put forward more demands for intelligent, safe and energy-saving houses. Traditional smart homes have the following three problems: (1) Most of them use bus technology to connect home devices together, which brings problems such as complex home wiring, difficult maintenance, and high maintenance costs. (2) There is little collection of indoor environmental information. As the global air quality is declining, indoor gas detection is particularly important. (3) Users need to have a certain understanding of intelligent equipment, the operation of switches, buttons and terminal equipment i...
