摘要
针对结构强度试验测量系统采集触发的两种基本模式,考虑了多通道测量时出现的触发切换问题,提出了一种可控采集触发切换技术。该技术利用外接电源,设计了触发切换电路,能够通过软件和硬件同时实现触发切换。设计方案保证了设备的可扩展性,能够较好地满足测控需求。
Aiming at two basic modes of acquisition and trigger for measurement system of structure strength test,the trigger switch problem in multichannel measurement is considered,and a controllable acquisition trigger switch technology is presented.The external power is used to design the trigger switch circuit,and the trigger switch can be realized by software and hardware.The design scheme ensures the expansibility of the equipment,and it can meet the requirements of the measurement and control.
