【摘要】：車路協(xié)同系統(tǒng)(Cooperative Vehicle Infrastructure System,簡稱CVIS)作為ITS的重要子系統(tǒng),被認為是提高道路交通可靠性、安全性和減少環(huán)境污染的有效手段之一。近年來,電子信息和無線通信技術(shù)的迅速發(fā)展與應(yīng)用,推動了CVIS的發(fā)展,其中有效的無線通信網(wǎng)絡(luò)是確保實現(xiàn)車路協(xié)同系統(tǒng)的關(guān)鍵。本文對面向車路協(xié)同應(yīng)用的無線藍牙網(wǎng)絡(luò)進行研究與開發(fā),通過對車路協(xié)同系統(tǒng)中現(xiàn)有的短距離無線通信技術(shù)進行分析比較,提出利用藍牙技術(shù)組建無線通信網(wǎng)絡(luò)來實現(xiàn)車路協(xié)同系統(tǒng),并對國內(nèi)外藍牙組網(wǎng)現(xiàn)狀及常見算法進行了研究,對藍牙組網(wǎng)的可行性進行了分析。本文主要通過研究藍牙BLE協(xié)議,結(jié)合智能道釘及其核心模塊CC2540,以德州儀器提供的BLE軟件開發(fā)包為軟件平臺,設(shè)計開發(fā)了基于藍牙通信的智能道釘主從節(jié)點以及網(wǎng)絡(luò)收集器,實現(xiàn)了智能道釘節(jié)點的數(shù)據(jù)采集,數(shù)據(jù)傳輸以及網(wǎng)絡(luò)數(shù)據(jù)收集,進而構(gòu)建了面向車路協(xié)同應(yīng)用的無線藍牙網(wǎng)絡(luò)——以網(wǎng)絡(luò)收集器為主節(jié)點,以智能道釘為從節(jié)點的星形網(wǎng)絡(luò)。其次,本文還設(shè)計開發(fā)了由兩個智能道釘從節(jié)點通過SPI串口通信組成的橋節(jié)點,并以此為基礎(chǔ)設(shè)計了面向車路協(xié)同應(yīng)用的藍牙線性散射網(wǎng)。此外,本文設(shè)計了PC上位機軟件,實現(xiàn)了對網(wǎng)絡(luò)收集器收集到的數(shù)據(jù)進行處理以及顯示的功能,并結(jié)合TI提供的測試軟件BTool和BLE Device Monitor對無線藍牙網(wǎng)絡(luò)進行了性能測試,分析了微微網(wǎng)的覆蓋范圍、建立連接時間、數(shù)據(jù)傳輸速率、傳輸穩(wěn)定性以及星形微微網(wǎng)的數(shù)據(jù)采集。最后,本文結(jié)合車路協(xié)同應(yīng)用對網(wǎng)絡(luò)性能進行了分析,證明了所設(shè)計的無線藍牙網(wǎng)絡(luò)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.
