【摘要】：车路协同系统(Cooperative Vehicle Infrastructure System,简称CVIS)作为ITS的重要子系统,被认为是提高道路交通可靠性、安全性和减少环境污染的有效手段之一。近年来,电子信息和无线通信技术的迅速发展与应用,推动了CVIS的发展,其中有效的无线通信网络是确保实现车路协同系统的关键。本文对面向车路协同应用的无线蓝牙网络进行研究与开发,通过对车路协同系统中现有的短距离无线通信技术进行分析比较,提出利用蓝牙技术组建无线通信网络来实现车路协同系统,并对国内外蓝牙组网现状及常见算法进行了研究,对蓝牙组网的可行性进行了分析。本文主要通过研究蓝牙BLE协议,结合智能道钉及其核心模块CC2540,以德州仪器提供的BLE软件开发包为软件平台,设计开发了基于蓝牙通信的智能道钉主从节点以及网络收集器,实现了智能道钉节点的数据采集,数据传输以及网络数据收集,进而构建了面向车路协同应用的无线蓝牙网络——以网络收集器为主节点,以智能道钉为从节点的星形网络。其次,本文还设计开发了由两个智能道钉从节点通过SPI串口通信组成的桥节点,并以此为基础设计了面向车路协同应用的蓝牙线性散射网。此外,本文设计了PC上位机软件,实现了对网络收集器收集到的数据进行处理以及显示的功能,并结合TI提供的测试软件BTool和BLE Device Monitor对无线蓝牙网络进行了性能测试,分析了微微网的覆盖范围、建立连接时间、数据传输速率、传输稳定性以及星形微微网的数据采集。最后,本文结合车路协同应用对网络性能进行了分析,证明了所设计的无线蓝牙网络的有效性和可靠性。
[Abstract]:As an important subsystem of ITS, Cooperative Vehicle Infrastructure system (CVIS) is considered to be one of the effective methods to improve the reliability, safety and reduce environmental pollution of road traffic.In recent years, the rapid development and application of electronic information and wireless communication technology have promoted the development of CVIS, among which effective wireless communication network is the key to ensure the realization of vehicle-road coordination system.In this paper, the research and development of wireless Bluetooth network for vehicle-road cooperative application is carried out, and the existing short-range wireless communication technology in vehicle-road cooperative system is analyzed and compared.In this paper, a wireless communication network based on Bluetooth technology is proposed to realize the vehicle-road cooperation system. The present situation and common algorithms of bluetooth networking are studied, and the feasibility of Bluetooth networking is analyzed.Based on the research of Bluetooth BLE protocol, combining with intelligent nail and its core module CC2540, and taking the BLE software development kit provided by Texas Instruments as the software platform, this paper designs and develops the master slave node and network collector based on Bluetooth communication.The data collection, data transmission and network data collection of intelligent spike nodes are realized, and then a wireless Bluetooth network, which is based on network collector and slave node, is constructed.Secondly, a bridge node which is composed of two intelligent spike slave nodes through SPI serial port communication is designed, and a bluetooth linear scattering network for vehicle-road cooperative application is designed.In addition, the PC software is designed to process and display the data collected by the network collector, and the performance of the wireless Bluetooth network is tested by combining the testing software BTool and BLE Device Monitor provided by TI.The coverage of piconet, connection time, data transmission rate, transmission stability and data acquisition of star piconet are analyzed.Finally, the performance of the wireless Bluetooth network is analyzed in this paper, which proves the effectiveness and reliability of the designed wireless Bluetooth network.
