| As an important part of modern commercial aircraft, avionics system merges airborne information together and shares system resources, coordinating with other systems to complete the flying mission. In order to shorten the development cycle and reduce the cost of resources, during the research of avionics system, series of function test and simulation experiments must be done. Through the establishment of the evaluation platform, avionics simulation and evaluation system simulates crosslinking relationship, functional logic and communication process in the simulation experiment. Based on the specific simulation evaluation system, data monitoring system is designed to monitor, analysis, display and record interactive data.First of all, according to the design requirements of the system, the crosslinking relationship of avionics simulation and evaluation system is analyzed. At the same time, the system interactive content is defined.Secondly, the software architecture of the system is designed. Based on system interactions, it puts forward the overall design scheme and studies on the mutual communication process and specific functional modules in detail. The module includes the process of data collection, data display and data online-offline analysis. In order to improve the overall system efficiency, multi-threading technology is used to operate system tasks in independent threads and the multimedia timer is used to collect data. During the process of data offline analysis, NNAF data mining algorithms is applied to analyze system data.Finally, it designs friendly interactive interface and applied to the process of communication and navigation airworthiness evaluation. The result shows that the system is able to monitor data information of evaluation system. At the same time, it evaluates the performance and status of evaluation system. It provides the important data output and theory basis to the process of avionics system development and evaluation. |
