【摘要】：車聯(lián)網(wǎng)是通過車與車、車與路邊基礎(chǔ)設(shè)施等通信手段,實現(xiàn)對車輛的屬性和狀態(tài)信息進(jìn)行提取和有效利用,從而為人民提供更加方便出行的服務(wù)。近年來,車聯(lián)網(wǎng)的相關(guān)理論不斷完善技術(shù)不斷成熟,但一直缺乏足夠的基礎(chǔ)設(shè)施進(jìn)行進(jìn)一步的驗證和研究。傳統(tǒng)的交通仿真軟件對于車輛和路網(wǎng)的仿真有著良好的效果,但是缺失通信仿真功能,也不能很好支持車聯(lián)網(wǎng)研究成果的驗證需求。本文在傳統(tǒng)交通仿真軟件TransModeler的基礎(chǔ)上進(jìn)行了二次開發(fā),利用其提供的接口和事件機(jī)制,模擬了車聯(lián)網(wǎng)中V2V通信的過程。系統(tǒng)將交通仿真與通信仿真結(jié)合起來,為車聯(lián)網(wǎng)提供了有效的仿真驗證工具。全文首先介紹了相關(guān)背景知識,并對TransModeler交通仿真軟件的工作機(jī)制和開發(fā)方式,和V2V通信的工作模式進(jìn)行了重點說明;然后分析了 V2V通信過程中的主要功能需求,設(shè)計了總體的模塊劃分;在各模塊中,按照功能分布設(shè)計了主要的類的結(jié)構(gòu)和方法,并完成了對于各個關(guān)鍵問題的處理的流程設(shè)計,實現(xiàn)了原型系統(tǒng);對主要功能進(jìn)行了測試,并通過應(yīng)用案例驗證了原型系統(tǒng)的可用性;最后總結(jié)了論文主要完成工作,并提出了進(jìn)一步的工作方向。
[Abstract]:The vehicle network realizes the extraction and effective utilization of the attribute and status information of the vehicle through the means of communication between the car and the car, the vehicle and the roadside infrastructure, so as to provide the people with more convenient service to travel. In recent years, the related theories of vehicle networking have been matured, but there has been a lack of sufficient infrastructure for further verification and research. The traditional traffic simulation software has a good effect on the simulation of vehicle and road network, but the lack of communication simulation function can not support the verification requirements of vehicle networking research results. In this paper, based on the traditional traffic simulation software TransModeler, the secondary development is carried out, and the process of V2V communication in the vehicle network is simulated by using the interface and event mechanism provided by it. The system combines traffic simulation with communication simulation, and provides an effective simulation verification tool for vehicle networking. This paper first introduces the relevant background knowledge, and focuses on the working mechanism and development mode of TransModeler traffic simulation software, and the working mode of communication with V2V. Then the main functional requirements in the process of V2V communication are analyzed, and the overall module partition is designed. In each module, the structure and method of the main classes are designed according to the function distribution, and the flow design of dealing with each key problem is completed, and the prototype system is realized. The main functions are tested, and the availability of the prototype system is verified by an application case. Finally, the main work of the paper is summarized, and the further work direction is put forward.
