Design of flight data recorder system testing device based on virtual instrument

本文介绍基于虚拟仪器技术飞行参数记录系统检测设备的功能需求,分析硬件和软件的设计方案,讨论直流信号生成与检测模块、12位并行码生成与检测模块等设计问题。采用虚拟仪器技术,在PC总线结构基础上可对飞机飞行参数系统整体和各分部件的性能进行全面检测。检测系统具有硬件可靠性高、软件可移植和可扩充的特点,性价比优良。

In this paper, a flight data recorder system testing device is introduced which is based on virtual instrument. Its design scheme, including its function, hardware and software, as well as the direct current signal generator and modularized testing, bring about twelve bits collateral code and modularized testing of question to be designed are discussed. The hardware of this device has good reliability, and the maintainability and extensibility of software are very well, all of these advantages make this device has high performance to price ratio.
