Design Of Beidou Intelligent Location Service Platform Based On CPS

People are more and more close to the Internet information,and desiring for more information access to the Internet and serve our lives and work,especially physical information such as location information.CPS(Cyber-Physical System),which can change the interaction between people and the physical world in the future,is also looking forward to the effective access of location information.Through the monitoring and recording of the target location information,we can analyze the moving track of the target,the hot spot of the movement,and can also predict the route of action and the traffic congestion.In this paper,based on the system architecture of CPS,designed and developed the Beidou intelligent location service platform in accordance with the specification of the Ministry of communications.The system provides a unified and standard terminal access interface,which can realize the real-time tracking of the terminal and the replay of the historical track.The terminal and platform interact with each other through feedback loops,so the platform can modify the navigation line according to the location information uploaded by the terminal.The platform is divided into three parts:service processing module,communication module and application module.The communication module is responsible for communicating with the terminal,and the service processing module is responsible for the core logic service processing of the platform,and the application module mainly provides visual interaction interface.This paper focuses on the key problems in the design of the platform:the problem of inter module communication is too complex,and the coupling between modules is strong.A two-way communication mechanism is proposed to realize separate read and write of data,simplify communication process;realize remote call system and weaken module coupling.Finally,the function and performance of the platform are tested.The test results show that the platform function is normal,and the performance meets the requirements.
