Ads-b Map Database Maintenance Management System Development And Research

ADS-B system is vital to air traffic control, especially to flight training in Civil Aviation Flight University of China (CAFUC). ADS-B can greatly enhance the safety of flight training, improve avoid collision capability of the aircraft, help the aircraft intercept flight information, enlarge the capacity of training airspace, reduce vertical separation, boost controllers'capability of monitoring the sky and the airport as well as increase work efficiency of controllers.ADS-B, which is widely used in CAFUC, is a new technology in Civil Aviation Flight University of China, even in China. Map data, the core of ADS-B, stores all GPS map of the system and all data of terminal indication modules. Establishment and maintenance of ADS-B map data is quite difficult due to its high integration. As a user of the system, all controllers, if they desire to establish, renew and maintenance home airport data, must acquire basic ATC knowledge, familiarity of document structure of the system together with computer knowledge base. To meet this requirement is hard in CAFUC or even in our country.After thorough analysis and study of the map data, the author, with the help of computer engineer, develops ADS-B Map Data Management System which is based on VB software. The software system for building a friendly user interface simple management and operation, the system will be the end of the ads and b map of the data retrieved and displayed a database on the interface, users through this interface to a database for input, add, modify, keeping operations. and software through the input data format standards, procedures standardized, record check for the same fault of the legal means to guarantee the operation, to allow for new records. write a map of the database。Through friend and simple management and operation interface, can take the place of the old map data which is hard to establish and maintain, reduce controllers' heavy workload, guarantee safe and normal operation of ADS-B system database.Key components of this paper.Brief introduction of ADS-B system. The author, from the angle of its hardware system structure, airborne electronics, map database maintenance and management, strong points, functions and effectiveness compared with Radar, introduces ADS-B which is a relatively advanced ATC system, and points out its applied prospects, urgency and necessity in our country.Analysis and research of ADS-B map database. The author analyzes map database structure and display mode, finds out principles and ways of how ADS-B makes map based on database, its problems and solutions of maintenance and management.Design of ADS-B map database maintenance and management system. This part, based on analysis of users'needs and ADS-B map database, researches and develops the system of map database maintenance and management, further discusses design principles and process of the five modules, namely landmarks data module, airways data module, airspace module, airway points module and start and exit module.Implement of ADS-B system module functions The paper presents the process of each module's function while provides some procedure codes.Test of ADS-B System. The part discusses the test of the system, including test methods, strategies, requirements and process. The test, based on strict and full technological methods, ensures that the system can meet user's requirements.
