【摘要】：我国是农业大国,农业在发展国民经济中始终处于举足轻重的地位。目前,我国正处在传统农业向现代农业转型的关键时期。近年来,随着物联网技术的发展,物联网在农业领域中的应用不断深入。农业物联网的体系包含感知层、传输层和应用层；传输层和感知层进行农业生产感知数据的采集,应用层对感知数据进行处理应用；由于感知层采集的数据包含了设施、大田、水产和果园等农业各生产领域,加之数据的传输协议各异,使得农业感知数据具有了来源多、异构性强等特点；另外,农业物联网应用覆盖面越来越广,对数据的需求也不再单一,如在农业数据挖掘、农业产业链的构建、农产品质量安全体系构建等领域,往往需要农业各生产环节中多源异构的传感器数据,这就要求对传感器数据进行融合；因此,建立异构传感器数据接入服务,在农业物联网体系的传输层和应用层之间建立一个数据桥梁,将农业传感器数据进行融合,为上层应用平台提供数据服务就显得尤为重要。本文在对传感器数据适配接入方式研究的基础上,分析了国内外关于相关技术的研究现状,并根据农业感知数据的多源异构等特点,深入了解了国内外的感知数据接入手段和方法,分析了现有感知数据接入的业务流程,构建了标准的农业传感器数据模型,最终设计实现了多源异构农业感知数据接入系统；该系统包括传感器注册模块、感知数据适配模块和感知数据存储模块；用户通过传感器注册模块对要接入的传感器数据字段和传感器标识进行系统注册,完成注册后,当数据发送到系统,感知数据适配模块会利用动态资源分配策略,动态的为感知异构数据匹配对应的适配器；适配器将异构的传感器数据转化成统一的数据格式,最终由数据接入存储模块完成对感知数据的。该系统实现了多源异构农业感知数据的接入功能,有效的整合了感知数据资源,能够实现农业各生产环节中感知数据的融合,并统一为农业应用系统提供数据服务；系统在北京农业信息技术研究中心试运行半年,目前系统可靠稳定,运行正常。总之,本文的研究是对农业领域中感知数据接入管理的一种探索,对农业物联网体系的发展具有重要意义。
[Abstract]:China is a large agricultural country, agriculture has always been in a pivotal position in the development of the national economy. At present, our country is in the key period of transition from traditional agriculture to modern agriculture. In recent years, with the development of the Internet of things technology, the application of the Internet of things in the field of agriculture is deepening. The architecture of the agricultural Internet of things includes perceptual layer, transport layer and application layer; transport layer and perceptual layer collect the perceptual data of agricultural production; the application layer processes and applies the perceptual data; because the data collected by the perceptual layer includes facilities, the field, Various fields of agricultural production, such as aquatic products and orchards, together with different data transmission protocols, have made the agricultural perceptual data have many sources and strong heterogeneity. In addition, the application of the agricultural Internet of things is becoming more and more extensive. The demand for data is no longer single, such as agricultural data mining, the construction of agricultural industry chain, the construction of agricultural product quality and safety system, and so on. This requires the fusion of sensor data; therefore, the establishment of heterogeneous sensor data access services, building a data bridge between the transport layer and application layer of the agricultural Internet of things system, agricultural sensor data fusion, It is very important to provide data service for the upper application platform. Based on the research of sensor data adaptation and access, this paper analyzes the research status of related technologies at home and abroad, and according to the characteristics of multi-source heterogeneity of agricultural perceptual data, Deeply understand the domestic and foreign means and methods of perceptual data access, analyze the existing business process of perceptual data access, construct the standard agricultural sensor data model, and finally design and implement the multi-source heterogeneous agricultural perceptual data access system. The system includes a sensor registration module, a sensing data adaptation module and a perceptual data storage module. When the data is sent to the system, the perceptual data adaptation module uses the dynamic resource allocation strategy to dynamically match the corresponding adapters for the perceptual heterogeneous data; the adapter converts the heterogeneous sensor data into a uniform data format. Finally, the data access storage module completes the perception of the data. The system realizes the access function of multi-source and heterogeneous agricultural perceptual data, effectively integrates the perceptual data resources, can realize the fusion of perceptual data in agricultural production links, and provides unified data service for agricultural application system. The system was tested in Beijing Agricultural Information Technology Research Center for half a year. At present, the system is reliable and stable. In a word, the research of this paper is a kind of exploration of the perceptual data access management in the field of agriculture, which is of great significance to the development of the agricultural Internet of things system.
