Simulation Platform of the Aircraft Utility Management System

摘要

The paper explores the integrated hardware and software architecture of the simulation platform of the aircraft utility management system (UMS) and the correlative technologies, viz. the 1553B bus real-time (RT) communication, the RT nodes with the RT operation system Windows NT+RTX and the RT hardware, the RT middleware TAO, the non-master-slave probabilistic clock synchronization, the static task allocation based on the heterogeneous distributed immune and genetic algorithm, the dynamic task scheduling realized by the algorithm based on the heuristic Myopic Algorithm idea, Feedback Control, Real-Time Fault-Tolerant and Adaptive Earliest Deadline First (FC-FT-AEDF) in the operation system layer and the flexible dynamic scheduling based on metrics feedback framework in the middleware layer, the RT database management system actualized by main memory database, multi-level storage and RT-SQL, and the utility subsystem simulation. The platform has the advantage of redundancy, fault tolerance, failure reconfiguration and extendability.
