Research On Greenhouse Automation Control System Based On Speech Recognition Technology

The development direction of automatic greenhouse as facility agriculture, along with the development of the Internet and mobile automatic terminals can be a universal access, seek a more convenient and quick way of automatic control has great practical value.The existing experimental basis for greenhouses in this article, in view of the actual situation, the traditional greenhouse production and automation level are poor, research with speech recognition, data acquisition, automatic control, communications, and other means to constitute the greenhouse control system, installed within the traditional greenhouse environment data acquisition terminal, through the terminal data acquisition, computing and processing of greenhouse information will eventually be sent to our automatic terminal, and then use the automatic terminal to the sounds of the user information are collected, and then achieve the real time control of greenhouse.This paper made the following several aspects of research:1. Design and production environment of data detection terminal hardware, with C language to finish the driver of the greenhouse status display, data acquisition, data communication and so on, The DHT11 temperature and humidity sensor, after temperature and humidity data of the greenhouse are collected, and the data is transmitted to the automatic mobile terminal by the wireless module GTM900C.2. speech recognition software with Java language, embedded iFLYTEK speech engine, collected voice signal conversion information corresponding to the text, and the text information matching, matching success, send text messages of commends to the greenhouse.3. The lower position machine control center access to PC control command, corresponding to the greenhouse temperature and humidity data and control state return to the host computer control center, to achieve the information of real-time updates and information check.Voice recognition as a new technology, we in the speech signal after parsing, converts voice control signal to the corresponding machine control signal, control the greenhouse system, realize its effective monitoring and management, reduces the complexity of greenhouse control, makes the greenhouse control have stronger adaptability and flexibility.
