【摘要】：温室大棚作为一种现代农业生产的辅助手段,可以改善植物生长的周围环境,调节温室大棚内的环境为植物的最佳生长环境,还可以调节温室气候,减少外界四季变化和恶劣气候对温室大棚内植物的影响。因此,利用现代信息技术研究与开发智能温室大棚监控系统,进行多方位多点信息的精确采集和实时控制,是本课题研究的任务。本文基于PC主机和Android平台分析、开发和实现一种智能温室大棚监控系统。首先,通过需求分析和系统总体设计,采用CC2530嵌入式微处理器作为主控芯片,无线传感网络采用ZigBee网络技术实现系统硬件构架;利用ZigBee技术具有成本低、复杂度低、消耗低等特点实现系统信息采集与实施控制。其次,设计实现了 ZigBee无线传感网络,有终端节点、路由节点、协调器节点,终端节点上有各种功能不同的传感器,可以检测可燃气体并且采集温室大棚内的各种参数值,包括二氧化碳浓度、空气中温湿度、土壤中的温湿度、光照强度等数据,然后经过路由节点转发或者直接发送给协调器;协调器将数据通过串口发送给上位机的监控软件,上位机监控软件的界面是采用VC++6.0软件来实现界面的合理化设计与开发。最后,设计实现了 Android移动客户端,它可通过连接网络来获取数据,并辅助知识库予以指导用户,Android客户端采用Eclipse软件进行开发,实现系统报警与设备自动控制。经过不断地测试和改进,调试与试运行表明,基于Android平台的智能温室大棚监控系统可通过将各种传感器布置到温室大棚内的各个区域,来实现实时获取温室大棚内部的土壤温湿度、空气温湿度、二氧化碳浓度、光照强度以及检测可燃气体,实时自动或手动控制温室大棚的相关设备,保证温室大棚内环境是植物生长所需的最佳环境,提高植物的产量、品质。另外,该系统还可以通过Android平台、PC机等监控软件终端向用户提供实时监测信息、可燃气体预警信息、农业病虫害防治知识等,实现温室大棚的网络化管理,充分发挥物联网技术在农业生产中的作用。
[Abstract]:Greenhouse greenhouse, as an auxiliary means of modern agricultural production, can improve the surrounding environment of plant growth, regulate the environment in greenhouse greenhouse as the best growth environment for plants, and also adjust the greenhouse climate. To reduce the effects of four seasons and bad weather on plants in greenhouse. Therefore, using modern information technology to research and develop intelligent greenhouse monitoring system, accurate collection and real-time control of multi-location and multi-point information is the task of this subject. Based on the analysis of PC host computer and Android platform, an intelligent greenhouse monitoring system is developed and implemented in this paper. First of all, through the requirement analysis and the system overall design, uses the CC2530 embedded microprocessor as the main control chip, the wireless sensor network uses the ZigBee network technology to realize the system hardware frame, the use ZigBee technology has the low cost, the complexity is low, the wireless sensor network has the low cost, the complexity is low, Low consumption and other characteristics of the system information collection and implementation control. Secondly, the ZigBee wireless sensor network is designed and implemented. There are terminal nodes, routing nodes, coordinator nodes, terminal nodes and various sensors with different functions, which can detect combustible gases and collect various parameter values in greenhouse. Including carbon dioxide concentration, temperature and humidity in the air, temperature and humidity in the soil, light intensity and so on, and then forwarded or sent directly to the coordinator through the routing node; the coordinator sends the data to the monitoring software of the host computer through serial port. The interface of upper computer monitoring software is to use VC 6.0 software to realize the rational design and development of interface. Finally, the Android mobile client is designed and implemented, which can obtain the data by connecting the network, and assist the knowledge base to guide the user to use Eclipse software to develop the client, to realize the system alarm and the automatic control of the equipment. After continuous testing and improvement, debugging and trial operation show that the intelligent greenhouse monitoring system based on Android platform can be arranged to each region of greenhouse by various sensors. To achieve real-time access to soil temperature and humidity, air temperature and humidity, carbon dioxide concentration, light intensity, detection of combustible gases, real-time automatic or manual control of greenhouse greenhouse related equipment, To ensure the greenhouse environment is the best environment for plant growth, improve plant yield and quality. In addition, the system can provide users with real-time monitoring information, early warning information of combustible gases, knowledge of prevention and control of agricultural diseases and insect pests, and so on, through monitoring software terminals such as Android platform and PC, so as to realize the networked management of greenhouse sheds. Give full play to the role of Internet of things technology in agricultural production.
