【摘要】：时至今日,在环境监测、智能家居、智能电网、快递物流、健康护理、食品溯源、可穿戴设备等诸多领域,物联网都被广泛应用。物联网时代已经到来,人们通过触手可及的网络设备随时随地获取个性化的数据信息,并根据需求做出信息反馈及相应决策的场景已成为现实。现有物联网三层体系中异构传感器组成的感知层接入标准不一,数据格式不尽相同成为应用层发展阻碍。针对以上弊端,旨在解决异构传感器接入问题,建立统一数据格式,实现数据开放、共享。提出一个基于REST架构风格的智能传感器网服务平台,设计了一种网络化智能节点作为感知层网关模型,对资源数据建模,实现了统一开放的RESTful Web API,在研究物联网现状的基础上,分析总结物联网发展情况和未来趋势;在研究异构传感器和接入层智能网关的基础上,对数据资源进行解析,通过抽象建模实现数据格式统一化;在研究REST架构风格Web Service的基础上,设计了服务平台开放接口,实现了设备层与应用层之间多种格式的双向实时数据交互;最后,以具体应用场景为例进行可行性验证,总结智能传感器网服务平台方案的成果和不足,以期推动物联网长远发展。
[Abstract]:Nowadays, the Internet of things is widely used in many fields, such as environmental monitoring, smart home, smart grid, express logistics, health care, food traceability, wearable devices and so on. With the advent of the Internet of things era, it has become a reality that people can get personalized data information at any time and anywhere through the network devices, and make information feedback and corresponding decision-making according to the needs. In the three layers of the Internet of things, there are different access standards for heterogeneous sensors in the sensing layer, and different data formats are obstacles to the development of the application layer. In order to solve the problem of heterogeneous sensor access, to establish a unified data format, to achieve open and shared data. This paper proposes an intelligent sensor network service platform based on REST architecture, designs a network intelligent node as the gateway model of perception layer, models the resource data, and realizes the unified and open RESTful Web API, based on the research of the Internet of things. Based on the research of heterogeneous sensors and intelligent gateway of access layer, the data resources are analyzed, and the data format is unified through abstract modeling. Based on the research of REST architecture style Web Service, the open interface of service platform is designed to realize the two-way real-time data interaction between device layer and application layer. This paper summarizes the achievements and shortcomings of the intelligent sensor network service platform in order to promote the long-term development of the Internet of things.
