[Abstract]:As the development direction of facility agriculture, with the rapid development of the Internet and the popularization of mobile intelligent terminals, it is of great practical value to seek a more convenient and rapid intelligent control mode. In this paper, the existing greenhouse is selected as the experimental basis, aiming at the actual situation of low yield and low automation level of the traditional greenhouse shed, this paper studies the use of speech recognition, data acquisition, automation control, etc. Communication technology and other means constitute greenhouse control system. In the traditional greenhouse installed a variety of environmental data collection terminal, through these terminals to the greenhouse data collection, calculation and processing, and finally the greenhouse information to our intelligent terminal, Then the intelligent terminal is used to collect the user's voice information and realize the real-time control of the greenhouse. This article has done the following several aspects of research: 1. The hardware of environment data detection terminal is designed and manufactured, in which the driver program of greenhouse state display, data acquisition, data communication and so on is written in C language. The temperature and humidity data of greenhouse are collected by DHT11 temperature and humidity sensor. And the collected data through the wireless module GTM900C to send to the smart phone terminal. 2. 2. The speech recognition software is written with Java language, and the speech engine of iFLYTEK is embedded. The collected speech signal is converted into the corresponding text information, and the text information is matched successfully. Send the control command to the greenhouse control center by SMS. 3. After the control command of the upper computer is obtained, the temperature and humidity data and the control state of the greenhouse are transmitted back to the upper computer control center, so that the information can be updated and verified in real time. Speech recognition is to convert the speech control signal into the corresponding machine control signal, and then transmit the signal to the corresponding control system through the data communication system, and then control the whole greenhouse system. It makes greenhouse control more adaptable and flexible.
