The Implementation Of ChangBei Airport Ring Network Transmission

The Changbei International Airport construction was put into use in 1999, from the point of the civil aviation air traffic control system development, whether it’s available airspace resources, busy route and airport capacity, facilities or system scale, overall automation function efficiency, control ability, etc., as well as the personnel quantity and quality, can’t fully adapt to the growing atc of air traffic operation security requirements. Especially the high level of Nanchang hand over Shanghai, with the atc automation control demand caused by the security equipment operation correlation between deepened gradually, for atc transport security and reliability of the core business, are facing severe challenges. At the same time, along with the rapid development of electronic technology and computer technology development, and the speeding up of the integration of management, the high rate transmission business requirements, such as computer room environment monitoring, video monitoring system, OA system, flight integration requires high rate, high bandwidth and low error transmission network for its service, and the civil aviation atc of jiangxi branch of most of the signal transmission between each station, each device also is medium transport with copper cable is creasing. Therefore, all kinds of transmissions are independent on each other, and unable to form a unified network management, to satisfy new business information exchange of civil aviation in accurate, timely and clear requirements.Papers analysis and research the construction of the Changbei International Airport, on the basis of the local SDH ring network, based on the functions of SDH optical transmission network, the main form of network, network self-healing protection ability, subnet connection protection, hardware and software routine maintenance, fault analysis and processing methods, studied the prosperous north airport transfer, VHF radar signal with high quality, the implementation and application of information signal transmission.
