【摘要】：设施农业是一种现代化的农业生产方式,它利用农业设施、工程技术和管理技术等现代化设备和技术,在可控环境下调节农作物生长的环境,降低农业生产对自然生产环境的依赖,同时充分利用环境资源和生物潜能,达到农产品的品质和产量的高效提升。农业生产环境数据信息监测是开展设施农业的前提条件,为了给管理者提供调节农业环境的决策依据,必须实时采集并记录农作物的生长环境。本论文以食用菌栽培菇房作为设施农业的例子,研究无线传感器网络在菇房环境监控中的应用。由于食用菌栽培区域有面积大的特点,而食用菌对环境敏感、产品价格不高,而无线传感器网络具有规模大、成本低、自组织等优势,非常适合应用于食用菌栽培菇房环境监测。本论文的主要研究工作如下：首先,结合菇房环境监控的需求,提出了典型的设施农业监控系统在应用中存在的问题和不足,分析了无线传感器网络的优势及其在菇房监控系统中的适用性。接着研究了菇房无线传感器网络监控系统要实现的功能和结构,设计了系统总体方案,以满足食用菌栽培区域规模大、菇房需求差异以及系统可靠性的特征。其次,对菇房无线传感器网络的路由技术进行了研究。针对菇房实际情况,选择节点部署方式,并为菇房无线传感器网络设计了一种基于菇房编号的能量均衡路由协议,以满足数据传输的需求,并降低和平衡网络的能量消耗,延长网络生存时间。接着,研究了菇房无线传感器网络监控系统的分级数据融合算法。该分级数据融合算法分为三级,采集的数据逐步在单个传感器节点、簇首节点和基站进行数据融合,以解决传感器网络中数据冗余的问题,提高数据监测的精度,大幅降低网络能耗,提升整个网络的性能。最后,搭建菇房无线传感器网络监控系统的实验平台,采用Microsoft Visual C++开发监控系统软件,进行系统实验验证。
[Abstract]:Facility agriculture is a modern mode of agricultural production. It uses modern equipment and technology, such as agricultural facilities, engineering technology and management technology, to regulate the environment in which crops grow in a controllable environment. To reduce the dependence of agricultural production on the natural production environment, and at the same time to make full use of environmental resources and biological potential, to achieve the efficient improvement of the quality and output of agricultural products, the monitoring of agricultural production environmental data information is the prerequisite for the development of facility agriculture. In order to provide the decision basis for the management to adjust the agricultural environment, it is necessary to collect and record the growing environment of the crops in real time. The application of wireless sensor network (WSN) in environmental monitoring of mushroom room is studied. Because of the large area of edible fungus cultivation, the edible fungus is sensitive to the environment, and the product price is not high, while the wireless sensor network has large scale and low cost. Self-organization and other advantages, very suitable for edible mushroom cultivation room environmental monitoring. The main research work of this thesis is as follows:. First of all, according to the needs of environmental monitoring in mushroom house, the problems and shortcomings of the typical facility agricultural monitoring system in application are put forward. The advantages of wireless sensor network and its applicability in mushroom room monitoring system are analyzed. Then, the function and structure of wireless sensor network monitoring system in mushroom room are studied, and the overall scheme of the system is designed. In order to satisfy the characteristics of large scale of edible fungus cultivation area, different demand of mushroom house and system reliability. Secondly, the routing technology of wireless sensor network in mushroom room is studied. According to the actual situation of mushroom room, the node deployment mode is selected, and an energy balance routing protocol based on mushroom room number is designed for the wireless sensor network of mushroom room. In order to meet the demand of data transmission, and reduce and balance the energy consumption of the network, prolong the network lifetime. Then, the hierarchical data fusion algorithm of the wireless sensor network monitoring system of mushroom room is studied. The hierarchical data fusion algorithm is divided into three levels. The collected data is gradually fused in single sensor node, cluster head node and base station. In order to solve the problem of data redundancy in sensor networks, improve the accuracy of data monitoring, significantly reduce the network energy consumption, improve the performance of the entire network. Finally, the experimental platform of wireless sensor network monitoring system in mushroom room is built, and the software of monitoring system is developed by Microsoft Visual C, and the system is verified by experiments.
