【摘要】：随着科学技术水平飞速发展,科学研究人员越来越关注与研究系统的物联网技术,物联网技术正在继互联网技术后又一次技术革命。借此契机,我国农业生产的智能化、信息化建设会随着物联网技术的崛起而为我国农业的长足发展起到积极作用。我国农村人口及劳动力逐年减少的现状,使我国对农业现代化的需求,及大力提高农业生产的效率,减轻务农人员的劳动强度势在必行,而农业规模化、农业生产的智能化和信息化是我国发展农业的主要内容之一。本文是从物联网在农业温室大棚生产的应用出发,深入研究此项技术与实际生产的对接方式,从三个层次的技术构建到具体实施都做了充分的阐述。本文研究的基于物联网技术在农业大棚监控系统中的应用,构建物联网技术为系统主结构,具有独立的工作过程的多模块运行模式。系统采集大棚内信息,包括温度、湿度、CO2浓度、光照及图像信息,都是利用基于ZIGBEE的无线传感网络来实现的。系统完成监测数据的采集、数据的传输及在终端的显示,并且可根据监测而得到的数据自动对相应的控制设备发送控制指令,从而实现系统自动控制。采用嵌入式硬件设备,可以满足系统低功耗及生命周期长的设计要求。为了能及时对作物的生长状态有所了解,本文设计的监控系统特意加入了视频监控环节,可通过视频设备定时的采集大棚内作物的生长状态图像信息,并且对采集的后的图像信息,通过图像识别处理技术做分析处理,可以对一些病害做出初步的诊断及预测。本文主要研究了图像的识别两个部分。
[Abstract]:With the rapid development of science and technology, scientific researchers are paying more and more attention to the Internet of things technology of the system, which is another technological revolution after the Internet of things technology. Information construction will play a positive role in the rapid development of agriculture with the rise of Internet of things technology. And vigorously improve the efficiency of agricultural production, reduce the labor intensity of agricultural workers is imperative, and the scale of agriculture, The intellectualization and informationization of agricultural production is one of the main contents of developing agriculture in our country. This paper is based on the application of the Internet of things in the greenhouse production of agriculture, and deeply studies the docking mode between this technology and actual production. Based on the application of Internet of things technology in the agricultural greenhouse monitoring system, the main structure of the system is to construct the technology of the Internet of things. The system collects the information in the greenhouse, including temperature, humidity and CO _ 2 concentration, illumination and image information. All of them are realized by the wireless sensor network based on ZIGBEE. The system completes the collection of monitoring data, the transmission of data and the display at the terminal, and can automatically send control instructions to the corresponding control equipment according to the data obtained from the monitoring. In order to realize the automatic control of the system, the embedded hardware equipment can meet the design requirements of low power consumption and long life cycle of the system. The video monitoring system designed in this paper specially adds the video surveillance link, which can collect the growth state image information of the crop in the greenhouse periodically through the video equipment, and analyze and process the image information after the acquisition, through the image recognition processing technology. Some diseases can be preliminarily diagnosed and predicted. In this paper, two parts of image recognition are studied.
