【摘要】：人们与互联网信息交互得越来越密切,越来越渴望更多的信息接入互联网并服务于我们的生活和工作,特别是像地理位置信息这样的物理世界信息。作为今后改变人们与物理世界交互的信息物理融合系统(Cyber-Physical System,CPS),更期待着地理位置信息的有效接入。通过对目标位置信息的监控和记录,可以分析目标运动轨迹、移动热点,还能预测行动路线、交通拥塞状况,并提出导航建议。本文基于CPS的构建设想,研发设计了符合交通部提出的规范的北斗智能位置服务平台。系统提供了统一规范的终端接入接口,实现终端的实时跟踪、历史轨迹回放等服务;终端和平台通过反馈循环相互影响,依据终端上传的位置信息,对其导航线路进行修正建议。位置服务平台分为业务处理模块、通信模块和应用模块三部分:通信模块负责与终端进行通信连接,业务处理模块负责平台的核心逻辑业务处理,应用模块主要提供可视化的交互界面。本文重点解决了平台设计过程中的关键问题:模块间通信过于复杂的问题;模块间耦合性强的问题。提出了双向通信机制,实现数据分开读写,简化通信过程;实现了远程调用体系,弱化模块耦合。最后,对平台的功能和性能进行了一定的测试,测试结果表明:平台功能运行正常,性能满足要求。
[Abstract]:People interact with the Internet more and more closely, and desire more and more information to connect to the Internet and serve our life and work, especially the physical world information such as geographical location information. As an information physical fusion system which will change people's interaction with the physical world in the future, it is expected to access the geographic location information effectively. By monitoring and recording the position information of the target, we can analyze the moving track of the target, move the hot spot, predict the route of action and traffic congestion, and give some advice on navigation. Based on the idea of CPS, this paper designs a Beidou intelligent location service platform which conforms to the specification proposed by the Ministry of Communications. The system provides a unified and standardized terminal access interface to realize terminal real-time tracking, historical track playback and other services, the terminal and platform through feedback loop interaction, according to the location information uploaded by the terminal, The navigation route is suggested to be revised. The location service platform is divided into three parts: communication module, communication module and application module. The communication module is responsible for the communication and connection with the terminal, and the service processing module is responsible for the core logic business processing of the platform. The application module mainly provides visual interactive interface. This paper focuses on solving the key problems in the platform design process: the communication between modules is too complex and the coupling between modules is strong. A bidirectional communication mechanism is proposed to realize data reading and writing separately, to simplify the communication process, to realize remote call system, and to weaken the coupling of modules. Finally, the function and performance of the platform are tested. The test results show that the function of the platform runs normally and the performance meets the requirements.
