【摘要】：随着城市化的快速发展,传统的城市感知方法已不能满足人们日益增长的需求,更智能化的智慧城市是城市的发展趋势。构建智慧城市的基础是高可靠性、高稳定性和高覆盖率的城市感知网络,该网络是把人、车、路、建筑物及环境等状态信息真正地融入到动态城市运行环境中来,从而提升城市运行效率和服务水平。本文对城市感知网络中如何高效并可靠地进行数据收集问题进行了研究。 首先对论文所涉及的城市数据收集技术进行了分析介绍。本文中的数据收集技术按照数据传输的过程分为数据采集和数据传输汇聚两个阶段,对数据采集技术中固定节点采集和移动节点采集方式的特点及存在的问题进行了分析；数据传输方式主要包括有线传输及无线传输,包含骨干网与接入网两种网络；在数据汇聚技术部分主要介绍了基于移动汇聚节点的数据汇聚方式。以上内容为后文所描述的基于公共交通的城市感知模型提供了理论基础。 分别研究分析了基于公共交通的车路协同感知技术和车路信息交互技术。在此基础上提出了基于公共交通的车路协同感知模型,并进行了详细的分析介绍。 为实现高效并可靠的城市感知数据收集,本文基于公共交通的城市感知模型,提出了采用SDMA技术中线性解相关技术的城市感知数据收集方案。目的是减少城市感知网络的能量消耗,缩短数据传输时间,提高网络性能及传输效率。通过仿真验证与结果分析,验证了该方案可以实现更加高效地进行城市数据收集。
[Abstract]:With the rapid development of urbanization, the traditional urban perception method can not meet the increasing needs of people, more intelligent city is the development trend of the city. The foundation of a smart city is a city perception network with high reliability, high stability and high coverage. The network is a real integration of people, cars, roads, buildings and environment into the dynamic urban environment. In order to improve the efficiency of urban operation and service level. This paper studies how to collect data efficiently and reliably in urban perceptual network. Firstly, the urban data collection technology involved in this paper is analyzed and introduced. The data collection technology in this paper is divided into two stages according to the process of data transmission: data acquisition and data transmission convergence. The characteristics and problems of fixed node acquisition and mobile node acquisition in data acquisition technology are analyzed. The data transmission mode mainly includes wired transmission and wireless transmission, including backbone network and access network. In the part of data convergence technology, the data convergence mode based on mobile convergence node is mainly introduced. The above provides a theoretical basis for the urban perception model based on public transport described later. This paper studies and analyzes the vehicle-road cooperative sensing technology and the vehicle-road information interaction technology based on public transportation. On the basis of this, the model of vehicle-road cooperative perception based on public transportation is proposed and analyzed in detail. In order to achieve efficient and reliable urban perceptual data collection, based on the urban perception model of public transport, this paper proposes a method of urban perceptual data collection based on linear decoupling in SDMA technology. The purpose of this paper is to reduce the energy consumption, shorten the time of data transmission, and improve the network performance and transmission efficiency. Through simulation and result analysis, it is verified that this scheme can collect urban data more efficiently.
