【摘要】：自动化温室作为设施农业的发展方向,伴随着互联网日新月异的发展以及移动可持智能终端的全面普及,寻求一种更加方便快捷的智能控制方式具有很大的现实价值。本文选择现有的温室大棚作为实验基础,针对传统温室大棚产量不高,自动化水平低等实际现状,研究使用语音识别,数据采集,自动化控制,通信技术等多种手段构成温室控制系统。在传统的温室内安装多类型的环境数据采集端,通过这些终端对温室进行数据采集、运算和处理,最终将温室信息传送至我们的智能终端,再使用智能终端对用户的语音信息进行采集,进而实现对温室的实时操控。本文做了下面几个方面的研究：1.设计并制作环境数据检测终端硬件,其中使用C语言编写温室状态显示、数据采集、,数据通信等方面驱动程序,通过DHT11温湿度传感器,采集温室的温湿度数据,并将采集到的这些数据通过无线模块GTM900C以短信的方式发送到智能手机终端。2.运用Java语言编写语音识别软件,嵌入科大讯飞的语音引擎,将采集到的语音信号转换为对应的文本信息,并将这些文本信息进行匹配,匹配成功以后,将控制命令以短信的方式发送到温室下位机控制中心。3.下位机控制中心获取到上位机控制命令以后,将温室对应的温湿度数据和控制状态回传到上位机控制中心,从而达到信息的实时更新和信息校验。语音识别是将语音控制信号转换为对应的机器控制信号,再通过数据通信系统,将信号传输给对应的控制系统,进而控制整个温室系统,使得温室控制有更强的适应性和灵活性。
[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.
