The application of TTP protocol in aircraft electrical system

Study of the aircraft electrical power distribution system based on TTP protocol typical signal communication, The simulation analysis of the real-time, applicability and safety of TTP bus in the distributed aircraft electrical power distribution system. This article analyzes the structure and communication mechanism to the time triggered architecture of TTP bus and the traditional event trigger, research of the typical signal of the aircraft electrical power distribution system communication structure, communication of information and real-time requirements. Using TTP hardware and software development tools for modeling and Simulation of main unit signal communication electrical power distribution system based on typical signal level division of electrical power distribution system, the transmission of signals between each node on monitoring system, observe message transmission timing correctness, redundancy and time delay. The results show that TTP/C protocol has a strict time deterministic, reliability and stability, provide solutions for data communication of safety critical system for automotive and aerospace field.
