【摘要】：近年来,伴随着我国物流业、旅游业等行业的快速发展,与之俱来的交通压力日益剧增。如今我国光私家车保有量就达到一亿辆,是十年前的15倍左右。不断加强的出行需求和物流压力对高速公路的通行率提出了新的要求和挑战,传统的MTC收费在收费站因效率低造成的车辆通行状态急需改变。国家顺应智能交通的发展趋势,将ETC不停车收费系统作为我国智能交通领域研究的排头兵。本文旨在我国现有的ETC不停车收费系统方案的基础上设计一款应用于ETC车道的系统软件。本文首先对采用5.8G频段的RFID技术的ETC道路收费系统的技术背景做了简要陈述。阐述了ETC在我国构建智慧城市,降低环境污染,提高社会整体服务水平等进程中带来的重要意义。针对我国使用的DSRC协议标准在高速道路收费站中计算机、路侧单元、车载单元三者之间的信息交互流程做了简要分析。同时也对车道计算机和路侧单元的通信接口方案、车道布局方案进行了对比分析和比较。接着对ETC车道子系统的工作原理和硬件构成以及作用做了详细的研究,明确了ETC车道子系统的主要功能,完成了车道子系统软件的功能和性能需求分析。在此基础上,设计实现了车道系统软件的整体框架和数据库,为系统的实现奠定了基础。在系统整体设计基础上完成了系统各个功能模块开发。系统具有以下特点:1.车道系统软件具备自动上班功能,在系统初始化完成以后系统便进入自动上班,操作员登陆后进入操作员上班模式,方便了操作员的上下班的快速切换。2.同时集成封闭式ETC车道收费出入口逻辑业务流程,根据出入口配置执行出口或入口功能。3.摒弃采用字符叠加器实现抓拍图像的文字信息叠加硬件实现方案,采用软件实现图像文字信息叠加的功能,节省成本。4.对收费站定期对收费车道交易流水记录循环采集模式进行改进,采用消息中间件实现交易流水记录的实时上传,同时采用开源组件,系统的稳定性进一步得到了保障。最后针对实验室自主研发的DSRC设备搭建测试平台,对车道软件的各个功能进行了详细的测试和分析。
[Abstract]:In recent years, with the rapid development of logistics, tourism and other industries in China, the traffic pressure has increased dramatically. Today, the number of private cars in China alone has reached 100 million. This is about 15 times what it was ten years ago. The increasing demand for travel and the pressure of logistics have put forward new requirements and challenges to the traffic rate of expressways. The traditional MTC charge in the toll station due to the low efficiency of the vehicle traffic status needs to be changed. The country conforms to the development trend of intelligent transportation. The ETC non-stop toll system is regarded as the vanguard of the research in the field of intelligent transportation in our country. The purpose of this paper is to design a system software applied to the ETC lane based on the existing scheme of the ETC non-stop toll system in our country. The technical background of ETC road toll system based on 5.8G band RFID technology is briefly stated, and the construction of intelligent city in China by ETC is expounded. The importance of reducing environmental pollution and improving the service level of society as a whole. Aiming at the DSRC protocol standard used in our country, the computer and road side unit are used in the toll collection station of high speed road. At the same time, the communication interface between the driveway computer and the road-side unit is also discussed. Then the working principle, hardware structure and function of ETC lane subsystem are studied in detail, and the main functions of ETC lane subsystem are clarified. The function and performance requirement analysis of lane subsystem software is completed. On this basis, the whole frame and database of lane system software are designed and implemented. It lays a foundation for the realization of the system. On the basis of the overall design of the system, it has completed the development of each functional module of the system. The system has the following characteristics: 1.The driveway system software has the function of automatic reporting. After the system has been initialized, the system goes to work automatically, and the operator logs in to the operator mode, which facilitates the operator to switch to and from work quickly. 2. At the same time, it integrates the closed ETC lane charge and exit logic business flow. According to the configuration of the entrance and exit, the function of exit or entry. 3. Abandon the hardware implementation scheme of character information superposition of the captured image, and use software to realize the function of image text information superposition. Saving cost. 4. improve the collection mode of income record cycle in toll lane transaction periodically, use message middleware to realize real-time uploading of traffic record, and adopt open source component at the same time, The stability of the system is further guaranteed. Finally, the test platform is built for the DSRC equipment developed independently in the laboratory, and the various functions of the driveway software are tested and analyzed in detail.
