Research On Key Technology Of Low-Altitude Airspace Management System Base On RUP

As China continues to open up low-altitude airspace, general aviation, as an advanced production tools and technical means, will play an increasingly important role in economic and social development, and expected future aircraft active in the low-altitude airspace increasingly dense. The traditional way of conducting low-altitude airspace management revealed many defects, therefore, how to use advanced computer information technology to improve the efficiency of low-altitude airspace management and reducing general aviation operations at low altitude airspace activity units with the air traffic control units in the burden of integrate a variety of air traffic control resources, reduce the cost of shipping flying the rapid development of general aviation, one of the key issues.Paper first analysis of low-altitude airspace management and operation of the main features of general aviation, based on an integrated management system for low-altitude airspace should have conducted a detailed study of the function and in accordance with the services provided by the system is divided into five subsystems. In the low-altitude airspace management services, system hardware design, through the existing navigation, surveillance and communication technologies, research on low-altitude airspace conflict detection based on the model improved to make them more in line with the actual operation of low-altitude airspace, based on construction costs and construction period of consideration, chose to apply to low-altitude airspace users of the technology and programs; software, service stations, taking into account the distribution and diversity of users and system maintainability, scalability, etc., choose the current maturity of the J2EE architecture and B/S mode. Finally, the paper designs RUP-based flight planning services, the software portion of subsystem. The same as with the other subsystems, the subsystem can also be divided into multiple modules in accordance with features, including: user management module, the flight plan filed with the state modules, and flight plan management module. In this paper, the software implementation process, in accordance with the data persistence layer, logic layer and presentation layer on each module design and implementation.
