摘　　要：电磁脉冲效应实验是对被试系统的模拟实验,在模拟器下开展,实验中需要测量被试系统内部的耦合场、感应电流和电压等效应参数。随着测量规模的增大,需要研制一种新的电磁脉冲同步触发系统,用于解决电磁脉冲效应实验参数测量中多台示波器的同步触发问题。该种电磁脉冲同步触发系统包括一种电磁脉冲效应实验触发信号测量系统和一种触发方法。效应实验触发信号测量系统放置于模拟装置下,用于测量触发信号。一种触发方法通过触发信号和同步触发装置去同步触发多台示波器。通过多次实验验证,该同步触发系统具有高可靠性和高稳定性,可以完成多台示波器的同步触发,在工程应用中实用性强,保证了实验的顺利完成。Electromagnetic pulse effect test is a simulation test of the tested system under large simulators. It’s necessary to measure the coupling field, induced current, voltage and other effect parameters in the test. With the increase of measurement scale, it’s necessary to develop a new electromagnetic pulse synchronous trigger system to solve the problem of synchronous trigger of multiple oscilloscopes in the measurement of electromagnetic pulse test parameters. The electromagnetic pulse synchronous triggering system comprises an electromagnetic pulse effect triggering signal measuring system and a triggering method. The effect trigger signal measurement system is placed under the simulator to measure the trigger signal. The invention relates to a trigger method, which triggers multiple oscilloscopes synchronously through a trigger signal and pulse signal generator. Through many experiments, it is verified that the synchronous trigger system has high reliability and stability. It can trigger multiple oscilloscopes synchronously, improve the experimental efficiency in engineering application and ensure the smooth completion of the experiment.
