[Abstract]:In recent years, with the rapid development of China's economy and the rapid development of car ownership, intelligent transportation has become an urgent problem to be solved in the domestic transportation industry. The prominent feature of intelligent transportation is to provide all kinds of needs according to the needs of traffic participants through the collection, processing, release, exchange, analysis and utilization of information. The network management system based on intelligent traffic is the core of intelligent traffic. The network management system provides professional, reliable and real-time data for the ever-changing road traffic. It provides a good basis for the popularization of intelligent traffic in the future. This system adopts wireless communication technology, GPS global satellite positioning technology, GIS Information technology, computer network technology and database technology have established a GPS monitoring center and a comprehensive satellite positioning system platform for road satellite vehicles which can be connected through various devices. The system consists of five parts: GPS monitoring center, line free communication platform, global satellite positioning system, vehicle positioning The overall architecture of this system is divided into six layers: application display, application service, basic service, data storage, data processing and data receiving. The data receiving layer is responsible for receiving all kinds of data from the terminal, and providing instruction and data to the terminal, providing two-way communication service. The data receiving layer provides data access in several ways, such as the direct connection of the terminal, the sending of messages, and so on. The terminal receives the data and inserts the data into the message queue of the system. At the same time, the data receiving layer also needs to deal with the various instructions and data sent to the terminal by the system. If the direct connection fails, the instructions can be sent through SMS. The data processing layer is responsible for reading the data received from the terminal from the message queue, analyzing the protocol, processing the data, and storing it into the database. The data storage layer contains two databases, one is a relational database and the other is an unstructured database. The relational database is used to store the relational basic data, the business data and the number of geographical spaces. Unstructured database is used to store unstructured data: video, pictures, and trajectories. The basic service layer is responsible for providing public components and services to the application service layer, such as report print service, role management, multimedia service, electronic map service and system management. The basic service layer is independently developed and upgraded to guarantee the connection. The application service layer is responsible for the business management of the system, provides the interface to the external system, and provides the unified identity authentication. The system management function of the application service layer can manage the vehicles of the subordinate branches at all levels, and the system provides various types of monitoring, inquiry and statistical analysis and other functions. The application display layer provides a variety of user interfaces, such as browsers, desktop clients, WAP browsers and so on, to meet various users' use of different devices for management and view. This system is mainly involved in two aspects: the monitoring management system with small concurrency and low real time: using B/S architecture, developing language using Java; using distributed industry. Service middleware deployment; providing linear extension; independent electronic map service can be invoked in the way of API. For large concurrency, a communication receiver that can handle mass data, the system handles data communication with the vehicle terminal: using the C/S architecture, developing the language using C# and C++; data is divided into relational data and non relational data Data, non relational data are structured storage scheme, and the simulation terminal can be built to carry out parallel testing. This system uses SOA service oriented architecture to realize the concept of car networking. It designs and constructs a SOA application model which is suitable for the car networking system, and carries out a specific model. Through the construction of the streaming media server, the video monitoring can be realized through the construction of the streaming media server. This system aims to dig into the industry requirements through the concept of intelligent traffic, SOA oriented service architecture, such as bus, logistics, rental, rental car, dangerous goods car, escort car. And other industry vehicles, provide a set of intelligent traffic based vehicle network management system design scheme, and give implementation. This system uses wireless communication technology, GPS global positioning technology, GIS technology, computer network technology and database technology, to establish a GPS monitoring center, the user can access the comprehensive road through the Internet. The satellite vehicle satellite positioning system platform. This system has also made a lot of explorations and attempts on various terminals, communication mode, data exchange standard, system reliability and stability and ease of use, and strives to introduce a comprehensive network management system with high adaptability, strong stability, reliable and easy to use.
