飞控计算机实时性分析与优化方法研究

Research on Real time Analysis and Optimization Method of Flight Control Computer

飞控计算机必须及时将飞行员的飞行控制信息传递给飞行控制,以控制飞行中的飞机,因此时间是飞控计算机定义的重要组成部分。分析了飞控计算机的实时性标准,研究了基于硬件辅助、纯软件的性能分析方法的利弊,提出结合使用源代码工具和硬件数据收集来实现高精准性能分析方法。根据分析信息,识别出飞控计算机实时性中的“短板”,提出性能分析和算法改进、代码对接这两种优化方法的应用。

The flight control computer must pass the pilot′s flight control information to the flight control in time to control the aircraft in flight.Therefore,time is an important part of the flight control computer definition.This paper analyzes the real time standards of flight control computers,and studies the advantages and disadvantages of hardware assisted,software only performance analysis methods.A combination of source code tools and hardware data collection is used to achieve high precision performance analysis methods.According to the analysis information,the“weak point”in the real time performance is identified,and the application of the two optimization methods of performance analysis and algorithm improvement and code docking are proposed.
