多通道同步数据采集的大当量爆炸场参数光电测试系统
|
摘要
针对战斗部爆炸场破片速度等参数测试中需要多点分布测试方法存在精度差,成本高的问题,提出了一种以爆炸火光作为触发信号源的多通道同步分布式数据采集系统;设计了光电触发模块将爆炸火光经过光电转换,信号调理形成触发信号源,多个数据采集单元的触发模块参数相同,保证其响应时间一致;采用多通道数据采集单元配合激光光幕破片数据采集可以构建多点测试系统;通过多次战斗部破片速度测试试验结果表明:在TNT当量为5 kg时,测试系统分别布设在距离爆心不同距离处,可以完成可靠触发并获得有效数据。
Aiming at the needing distribution system of parameters measurement,such as fragment velocity in warhead explosion and the deficiency of poor accuracy and high cost of existing methods,a multichannel synchronous distributed data acquisition system based on explosion of fire as the trigger signal source was proposed. A photoelectric trigger module was designed,which could transform from explosion fire to the trigger signal source after photoelectric conversion and signal processing. Every trigger module keeps same parameters,that can ensures that it's have corresponding time. Combining PXI data acquisition unit and laser screen fragments measurement unit can build testing system. The results show that the systems could work properly at different distance,when the TNT equivalent of warhead is 5kg.
