【摘要】：传统智能交通系统在建设上存在重复建设、管理效率低、交通数据闭塞等问题,无法满足现今交通领域的发展需求。智慧交通云计算平台则为智能交通系统的发展提供了全新的发展思路,通过将云计算领域技术应用于交通领域来打造一个统一的交通云生态圈环境。交通云平台充分发挥云计算技术特长,帮助企业和政府摆脱系统设计实现过程中计算机领域的细节问题,从而减少重复性劳动,专心于交通问题领域事业规划与发展,实现进一步细化职责分工与资源重分配,提高资源利用率。本论文设计的出发点就是通过融合现有云计算技术,针对交通领域在构建智能交通系统中常见的问题,给出智慧交通云计算平台的设计、实现方案。本文的主要研究内容有:1.后台管理平台设计与实现:本文设计的云平台后台管理采用“主-从”式结构,通过中央控制节点分发命令,云平台节点上客户端执行的模式。文中实现使用cfdo工具作为节点客户端,dsh作为中央控制节点,并给出了详细的实现方案。2.应用架构设计与案例实现:本文在Cloud Foundry平台应用架构基础上提出交通云平台的应用架构设计方案,将应用划分成智慧交通应用和交通核心应用。文中给出两种应用的层次结构关系和调用关系,对应用间通信问题给出了基于HTTP请求、基于企业服务总线和基于异步消息队列三种模型。3.扩展服务设计与实现:本文给出两种服务扩展的设计与实现方案,分别为基于元数据的交通数据服务和HBase服务。文中给出了两种服务的设计架构和实现,描述了两种服务实例的创建、删除流程。4.自动化部署管理平台设计与实现:本文采用Iaa S平台技术完善智慧交通云计算平台底层的平台支撑,通过Iaa S平台为提供交通云平台提供服务器管理支持,并设计平台管理的域结构。文中给出了基于v Sphere的交通云自动化部署管理平台的详细实现过程,说明工具准备和具体实施过程。本文提出了基于Cloud Foundry平台构建智慧交通云计算平台的设计思路,并针对平台构建设过程中后台管理、应用架构、服务、自动化管理等问题给出了设计思路与实现方案。通过融合现有云计算技术为智能交通系统的设计做出贡献。
[Abstract]:The traditional intelligent transportation system has many problems such as repeated construction, low efficiency of management, block of traffic data and so on, which can not meet the development needs in the field of transportation nowadays. Intelligent transportation cloud computing platform provides a new way of development for the development of intelligent transportation system, through the application of cloud computing technology in the field of transportation to create a unified transportation cloud ecosystem environment. The transportation cloud platform makes full use of cloud computing technology to help enterprises and governments get rid of the computer details in the process of system design and implementation, thus reducing repetitive work and concentrating on the career planning and development in the transportation problem field. To further refine the division of responsibilities and resource redistribution, improve resource utilization. The starting point of this paper is to design and implement the intelligent transportation cloud computing platform by integrating the existing cloud computing technology and aiming at the common problems in building intelligent transportation system in the field of transportation. The main content of this paper is: 1. Background management platform design and implementation: the cloud platform background management in this paper adopts the "master-slave" structure, through the central control node distributed commands, the cloud platform node on the client execution mode. In this paper, we use the cfdo tool as the node client and DSH as the central control node, and give a detailed implementation scheme. 2. Application Architecture Design and case implementation: based on the application architecture of Cloud Foundry platform, this paper puts forward the application architecture design scheme of traffic cloud platform, which divides the application into intelligent traffic application and traffic core application. In this paper, the hierarchy relation and call relation of two applications are given, and three models based on HTTP request, enterprise service bus and asynchronous message queue are given. Design and implementation of extended services: this paper presents two schemes of service extension, namely, metadata based traffic data service and HBase service. This paper gives the design and implementation of two kinds of services, describes the creation of two service instances, delete flow. 4. Design and implementation of automated deployment management platform: this paper adopts Iaa S platform technology to perfect the platform support of intelligent transportation cloud computing platform, and provides server management support to provide traffic cloud platform through Iaa S platform. And design the domain structure of platform management. In this paper, the detailed implementation process of traffic cloud automation deployment and management platform based on v Sphere is given, and the tool preparation and implementation process are explained. In this paper, the design idea of intelligent transportation cloud computing platform based on Cloud Foundry platform is put forward, and the design idea and implementation scheme of background management, application architecture, service and automation management in the process of platform construction are given. It contributes to the design of its by integrating the existing cloud computing technology.
