[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.
