飞行数据管理仿真系统软件设计及实现

Software Design and Implementation of the Flight Data Management and Simulation System

利用飞行数据驱动测试仪器模拟实际飞机飞行时产生的各种模拟量、离散量和总线信号,在实现了基于多种测试总线仪器的系统硬件平台的基础上,从实际软件需求出发,阐述了系统软件架构和应用程序层次结构,并详细介绍了系统软件设计及实现过程中的系统硬件资源模型化、可配置通用飞参解译、基于最小二乘曲线拟合的直流信号误差补偿、多线程编程等关键技术.

By using test instrument drived by flight data to stimulate analog, discrete and bus signals produced while a real aircraft flying, on the basis of realized system hardware platform based on multiple test bus instrument, taking account of actual software requirement, the paper describes system software architecture and application program structure and precisely introduces some key technologies in the procedure of system software design and implementation, such as system resource modeling, configurable general flight data decoding, DC signal compensating error based on least square curve fitting and multi-thread programming.
