Juniors develop smart home systems into annual scientific and technological figures

Information Times (Reporter Gao Jinhua Correspondent Zhang Yinting) As long as you align with a microphone, the electrical appliances at home are turned on and off, and they are completely under their control. Recently, Guangdong Agricultural Industry and Commerce Vocational and Technical College commended the top ten outstanding figures of “Moving the Campus” in 2012. Yang Qia, a major in electrical automation of the third-year mechanical and electrical department of the school, won the “Technology of the Year” by virtue of “Intelligent Home System Based on Language Recognition”.

Anyone can simply operate according to the Mandarin commands set by the program. In order to prevent voice confusion during speech, the system has a control switch that can be turned on only when the switch is turned on.”

Yang Qia said that he is a typical science and engineering man, and he is usually interested in small inventions. In September last year, when he browsed some online forums, he accidentally discovered the voice control system. "I feel particularly fun, I think if the home appliances can also be controlled by sound," he slowly explored and lasted for a long time. Month, completed the work. Yang Qia, who graduated this year, has already implemented his work as an electronic engineer in a company in Shantou, and his ability to innovate in science and technology has also played a major role in his job search.
