Avionics System Trusted Computing Network Key Technologies

In the future network warfare environment, all the terminal units of airplane, such as the airborne sensor, the executer, the display, the controller or the processor, should be regarded as the nodes of the network of new generation Avionics Integrated System(AlS), which answer for the different tasks of information collection, storage, processing and application. The research work of this dissertation is supported by the Aviation Science Foundation Project, named "A Study of Avionics Integrated System Oriented Switch Network with Transmission Fibre Channel" . Main research work includes the following several works topics:The development of the AIS was analyzed in this dissertation .For the future centric network warfare and the target of the trusted computing, a layered architecture of the new AIS unified network was brought forward, in which the research aim and the content of each layer was expatiated, and the AIS trusted computing network is defined.For the new model of the network layer, the airborne sensor was selected as the research object, because the number of the airborne sensors is larger and larger, and the data that need process become more and more in the new generation AIS. The high integration and networkization of the airborne multi-sensors have been the main developing direction. At the same time, the.networkization warfare objectively needs that the airborne sensors get rid of the limit of the single fighter plane, becoming one node of the whole warfare network. So, all the sensors in the networked warfare can share the information, by the way of collecting, processing and transmission.The key technology of the airborne sensors connected to the "Unified Network" in the networkization warfare environment was researched in this dissertation. The collecting, selecting and processing of the airborne sensor data in the network was analyzed and researched. Based on the characteristic of future airborne sensors, the development direction of the standardization and networkization was analyzed;the connection of the airborne sensor signals and the "Unified Network", as well as dataconversion, was implement;how to regard the sensors as one node of the AIS network was researched, a practical software and hardware design scheme was provided.The airborne multi-sensor integration and data fusion were researched. The special requirements of the sensors in AIS network were analyzed. The related theoretical model was brought forward, setting up one mode of the multi-sensor data fusion, the key algorithm of which was analyzed theoretically, and demonstrated by the Unmanned Aerial Vehicles (UAV) platform.
