【摘要】：伴隨著嵌入式技術和網絡通信技術的快速進步,物聯(lián)網迎來了其發(fā)展的黃金時代,大量不同類型的物聯(lián)網應用以及終端設備涌入了人們的視野。然而由于沒有形成一個統(tǒng)一的業(yè)界標準,不同的設備生產廠商以及標準機構都推出了自己的一套標準,這些標準涵蓋了物理層、通信層到服務層、應用層等各個層面,這種情況使得遵循不同通信協(xié)議、通信接口的設備、系統(tǒng)之間的消息交互非常困難。這種豎井式的物聯(lián)網設備、應用開發(fā)方式降低了物聯(lián)網設備及服務的可擴展性和互操作性,同時標準的不統(tǒng)一也造成了開發(fā)過程當中的一些重復性工作,增加了應用的開發(fā)成本,降低了開發(fā)效率。鑒于此,本文旨在提出一個物聯(lián)網設備接入的開發(fā)框架,提取設備開發(fā)過程當中的共性,提供一個設備服務的開發(fā)流程的標準。該框架包含了一個集中式的設備接入平臺以及客戶端設備驅動框架,通過這個框架,異構設備可以以一種統(tǒng)一的方式動態(tài)的接入到平臺,并通過形式統(tǒng)一的服務接口,向物聯(lián)網應用提供功能各異的物聯(lián)網設備服務。具體的內容包括:1.物聯(lián)網設備資源信息模型的設計與實現(xiàn):該模型對設備以及設備服務的元數(shù)據(jù)信息進行了定義與規(guī)范,對設備的服務接口和通信接口進行了描述。2.物聯(lián)網接入開發(fā)框架對外接口模型的設計與實現(xiàn):本文提出了一個驅動架構模型和設備服務模型,并分別對驅動架構的開發(fā)接口和服務模型的服務接口進行了定義。3.物聯(lián)網接入開發(fā)平臺系統(tǒng)的設計與實現(xiàn):利用Jersey,Netty,SSH等程序開發(fā)框架,并將上述2個模型以及M2M通信協(xié)議融合到系統(tǒng)當中,完成接入平臺以及設備開發(fā)框架的開發(fā),為底層設備提供了一種統(tǒng)一的開發(fā)與接入方式,并為上層應用提供設備服務。
[Abstract]:With the rapid progress of embedded technology and network communication technology, the Internet of things ushered in the golden age of its development, a large number of different types of Internet of things applications and terminal devices poured into people's horizons. However, due to the lack of a unified industry standard, different equipment manufacturers and standard organizations have introduced their own set of standards, which cover the physical layer, the communication layer to the service layer, the application layer and so on. This makes it very difficult to exchange messages between devices and systems that follow different communication protocols and communication interfaces. This kind of vertical Internet of things equipment, the application development method reduces the expansibility and the interoperability of the Internet of things equipment and the service, at the same time, the standard disunity also causes some repetitive work in the development process. The development cost of the application is increased and the development efficiency is reduced. In view of this, the purpose of this paper is to propose a development framework of device access to the Internet of things, to extract the commonness in the process of equipment development, and to provide a standard for the development process of equipment services. The framework includes a centralized device access platform and a client device driver framework. Through this framework, heterogeneous devices can access the platform dynamically in a unified way, and through a unified service interface. To provide Internet of things applications with different functions of Internet of things equipment services. The specific contents include: 1. Design and implementation of equipment resource information model of Internet of things: this model defines and standardizes the metadata information of equipment and equipment service, and describes the service interface and communication interface of equipment. 2. Design and implementation of external interface model of Internet of things access development framework: in this paper, a driver architecture model and device service model are proposed, and the development interface of driver architecture and the service interface of service model are defined respectively. Design and implementation of Internet of things access development platform system: using Jersey,Netty,SSH and other program development framework, and integrating the above two models and M2M communication protocol into the system, to complete the development of access platform and equipment development framework. It provides a unified development and access mode for the underlying equipment, and provides equipment services for the upper application.
