| FDMRS is a very important equipment of the next generation avionics which can realize colligation digital and intelligence. FDMRS also can realize colligation of avionics improve airplane security improve campaign capability and lighten airman' s burthen.This paper discusses the whole frame and realization of key technology deeply focuses on the FDMRS according to major programs, namely fifteen pre-research of air force.At the beginning, the paper reviews the history and current states of the development of avionics system. It states that the next generation avionics system must support separate function, high system colligation, high data transmission, distributed control and improve intelligent. Then, the paper discusses the key technology of FDMRS and bring forward whole frame of FDMRS.Based on analyzing the requirements and technology of avionics for new generation airplane, the paper introduces air system and ground system in detail.The paper firstly analysis advantage and disadvantage of FDDI and LPTB, then put forward construct of FDDI network and practical value.The paper put forward the structure of file storage design no-default file structure and default file structure particularly which can satisfy demand next generation avionics' demand in allusion to complex data and timely data transmission.Real time and security of Communication between air system and ground system is key technology. The paper researches interface mode of communication network structure of communication server and application of message which transmit ascending.In the method of data analysis, the paper researches application of data mining and knowledge database, then design frame of data mining automatism class engine and knowledge decision.In the research of establishment and management of database, the paper put forward classifies and managements of ground database, then confirm the structure. At last, the paper depicts relationship between database and program module mainly. |
