摘要: 针对某型飞机大气数据系统在地面静态条件下无法正常输出参数、难以与其他机载系统进行动态联试的问题,提出通过研制大气数据系统模拟器实现动态联试的方案,利用多线程和精确定时等方法提高模拟器的实时性。实验证明,该模拟器可以满足系统动态联试的要求。

Abstract: Aiming at the problem that Air Data System(ADS) can not achieve dynamic joint-trial with avionics because of its failure in normal parameter output in ground static state, this paper proposes a scheme which develops an ADS simulator to realize dynamic joint-trial. It uses the techniques such as multithreading and precise timer to improve simulator’s real-time performance. Experiment proves that the simulator can satisfy the requirement of dynamic joint-trial.

Key words: Air Data System(ADS), simulator, real-time performance
