【摘要】：近年来,随着社会信息化大潮的兴起,农业也向着信息化的方向快速发展,精准农业作为其核心已逐步进入研究推广阶段,而智能农业大棚作为精确农业的典型应用也取得了一定的发展。在此背景下,本文开展了基于ZigBee技术的智能农业大棚监控系统的研究与设计工作。以往提出的智能农业大棚主要关注于监测大棚数据,同时通过人工对环境要素进行调节。因而,系统控制的实时性不够高同时过于依赖于人的经验。针对这一不足,本文提出了基于ZigBee通讯协议的智能监测与控制系统。该系统具有不完全依赖人的经验、实时性高、无需现场布线、采集点设置灵活、采集点覆盖面积广阔、系统运行周期长、维护方便等优点,具有一定的研究与设计价值。论文的主要工作如下：(1)智能农业大棚的相关技术研究。调研了智能农业大棚的国内外研究现状,对各种通讯协议在农业大棚环境下进行了分析,给出了选择ZigBee技术作为监控系统通讯协议的原因,同时介绍了短距离无线传输技术ZigBee的起源、介绍、应用领域、体系结构与拓扑结构。(2)基于ZigBee的智能农业大棚监控系统的硬件设计。系统硬件部分采用四种不同的传感器分别探测环境的温度、湿度、光照、C02浓度信息,同时将信息通过刖D模块转换再利用单片机STC89C52进行检测就可以实现数据的采集工作。收集到的数据通过CC2430模块并利用ZigBee协议进行无线传输,从而实现数据实时采集的过程。(3)基于ZigBee的智能农业大棚监控系统的软件设计。通过获取系统传输的环境参数,进行智能调节,同时对用户提供友好的监测、查询、控制、管理功能,使之能够有效的对温室大棚进行监测和控制。结合MySql数据库,利用C#技术实现了系统软件的开发,为管理员提供了一个远程管理与监控温室大棚的智能平台。
[Abstract]:In recent years, with the rise of the tide of social informatization, agriculture is also rapidly developing towards the direction of information, precision agriculture as its core has gradually entered the stage of research and extension. The intelligent agricultural shed as a typical application of precision agriculture has also made a certain development. In this context. In this paper, the research and design of intelligent agricultural greenhouse monitoring system based on ZigBee technology is carried out. At the same time, the environmental elements are adjusted manually. Therefore, the real-time control of the system is not high enough and too dependent on human experience. This paper presents an intelligent monitoring and control system based on ZigBee communication protocol. The system is not completely dependent on human experience, high real-time, no need for on-site wiring, and the collection point setting is flexible. The system has many advantages, such as wide coverage area, long running period, convenient maintenance and so on. It has certain research and design value. The main work of this paper is as follows: 1) the related technology research of intelligent agricultural shed. All kinds of communication protocols are analyzed in the environment of agricultural greenhouse, and the reason why ZigBee technology is chosen as the communication protocol of monitoring system is given. At the same time, the origin, introduction and application field of short-range wireless transmission technology ZigBee are introduced. Architecture and topology. (2) the hardware design of intelligent agricultural greenhouse monitoring system based on ZigBee. The hardware part of the system uses four different sensors to detect the temperature, humidity and illumination of the environment. CO2 concentration information. At the same time, the data can be collected by converting the information through the D module and then using the STC89C52 of the single chip computer. The collected data can be collected through the CC2430 module and the ZigBee cooperator. For wireless transmission. The software design of intelligent agricultural greenhouse monitoring system based on ZigBee is realized. Through obtaining the environmental parameters of system transmission, intelligent adjustment is carried out. At the same time to provide friendly monitoring, query, control, management functions, so that it can effectively monitor and control the greenhouse. Combined with MySql database. The system software is developed by using C # technology, which provides an intelligent platform for remote management and monitoring of greenhouse.
