摘要:
 随着信息处理技术的不断发展，信息容量、处理速度和数据精度的要求越来越高。文中主要针对典型发动机管理系统参数，采用软硬件协同设计方法，实现了一套功能完备的数据采集系统。航空发动机气路及机械性能参数的采集工作已然成为飞行器状态监控与故障诊断至关重要的环节之一。为了实时了解发动机的运行状态，准确掌握运行参数的变化规律并实现一定程度的人机交互，系统硬件部分采用SoC作为核心，软件部分基于FPGA、嵌入式Linux以及CGI相关技术，使整个系统更具实用性、人性化。系统的开发主要借助于Xilinx ISE开发套件以及Linux交叉编译环境，设计了相关FIR数字滤波模块并编写模拟ADC驱动程序，最终通过CGI接口实现数据采集系统与上位机之间的通信，为状态监控与故障诊断系统设计提供了思路。
Abstract:
 With the continuous development of information processing technology, the requirement of information capacity, processing speed and data accuracy has become higher and higher. In connection with the typical parameter of engine management system analyzing, hardware/software collaborative design methodology is used to realize a fully functioning data acquisition system. Collecting performance parameters of aeroengine gas circuit and mechanical part has been a vital segment of aerocraft condition monitoring and fault diagnosis. In order to know the real-time running state of the engine,to grasp the changing law of operating parameters accurately and to achieve a certain degree of human-computer interaction,SoC is used as the core of hardware. With the help of embedded Linux and CGI technolo-gy,the whole system has become more practical and more user-friendly. The system development mainly depends on the Xilinx ISE de-velopment kit and the Linux cross compiler environment and the relevant FIR digital filter module and the preparation of simulated ADC driver are designed. By achieving the communication between data acquisition system and host computer through CGI interface,the sys-tem provides a way for condition monitoring and fault diagnosis system design.
