【摘要】 SN388仪器在山区施工经常遇到有线放炮产生数传中断的问题,文章对SN388地震仪有线放炮的原理深入分析后,指出该问题是由雷管引爆线产生的尖峰脉冲引起的,并提出了一种解决方法,即:在有线放炮连接线上连接低通滤波器,以防止尖峰脉冲干扰数据传输。更多还原

【Abstract】 The issue of data transmission interrupts produced by wire shooting is often met in mountainous areas by SN388 seismograph,after deep analysis of the wire shooting principle of SN388 seismograph,the article pointed out that the problem is caused by explorsion of cap producing the spike and presented a solved measure, that is,linking low pass filter in wire-shooting cable to prevent spike interfering data transmission.更多还原
