Design And Implementation Of Communication, Navigation And Identification System

The technology of avionics system is a communication control technology, based on the computer technology and applied in the system control and information transmission.This paper presents the studies of internal integration technology of communication navigation identification system(CNI).As a part of advanced avionics system, CM is operated to perform the tasks such as air-surfece, air-air and surface-air communication data transmissior^radio short-range navigation, radio landing-approach guide and identification friend-foe(IFF) etc.This paper describes the studies of the CM integration technology of avionics system and the design of the CNI integrated system based on the functional requirements. The works are composed of system plan design, system hardware design,system software design,system debugging and analysis of real-time capability etc. During the design, the system advanced ability, reliability, resources availability and the persistence are considered based on the characters of military products and the status of the instruments in the military field. The issues of bus control such as contradiction of reliability and advanced ability, mutuel exclusion of shared storage and handshaking signals generation were resolved. The CNI integrated system prototype was achieved and passed the performance testDuring the writing, the developmen work on AAS CIN integrated system engineering proyotype has been started, and already got the successful results, which meets the military products requirements.The design and achievement of the CNI integrated system prototype lays the foundation for CNI engineering application. We can believe that the engineering products will change completely the structure and the backward of our national existed airborne CNI and reduce the difference between our country and the developped countries in the field. The system is on the top rund in the national military aviation domain.
