基于千兆以太网传输的多路火工品等效系统设计（英文）

Design of multi-channel equivalent system for IED based on Gigabit Ethernet transmission

针对某飞行器中多路火工品起爆的脉冲信号及电路测试问题,根据火工品电参数设计了一种基于千兆以太网传输的多路火工品时序等效系统。系统以FPGA为测试平台,对多路等效电路的输出电压进行模数转换,并将转换后的信号进行有效性判断,通过千兆以太网传输至上位机进行波形显示。相比传统的火工品等效器,该系统不仅能够测试脉冲信号的有效性及电路的正常工作,也能够通过千兆以太网实现对脉冲信号的快速可靠性分析,解决了传统等效器对脉冲信号响应低速、滞后的问题。

To test the pulse signal of initiating explosive device (IED) in an aircraft,a multi-channel equivalent system for IED based on Gigabit Ethernet transmission is designed according to its electrical parameters. The output voltage of multi-channel equivalent circuit is converted by analog-to-digital converter (ADC). Then the validity of the converted signal is judged by field programmable gate array (FPGA). Finally,it is transmitted the host computer through Gigabit Ethernet for waveform displaying. Compared with the traditional equivalent equipment of IED,the designed system here can not only test the validity of the pulse signal and normal operation of equivalent circuit,but also realize fast and reliable analysis of pulse signal by means of Gigabit Ethernet. It solves the problems of low speed and lag of response of traditional equivalent equipment.
