Design of a Standard Signal Given Device

摘要: 设计一种飞机各类交直流电压形式的模拟量和开关量信号的给定装置，可以向机载飞参记录系统模拟提供机上大部分重要模拟量、开关量信号，用以对该参数采集通道的测量误差进行校准；同时可以原位检查所模拟的相关飞参通道的工作性能。最后结合实例，在机上原位检测火警参数采集通道来验证其采集通道的工作性能。

Abstract: A given device of analog and switch signals in various AC/DC voltage forms for aircraft is designed, which can provide analog and switching signals for aircraft, which can provide most of the im-portant analog and switching signals for the simulation of the airborne flight parameter recording system to calibrate the measurement errors of the parameter acquisition channel, and at the same time, the analog correlation can be checked in situ. Finally, combined with an example, the fire alarm parameter acquisition channel was detected in situ on the machine to verify the working performance of the acquisition channel.
