DSVM系列测振仪在爆破振动测试中的应用

介绍一种由电池供电、微机控制并可根据预设值自动地进行测试的振动测试仪，它无需很长的信号传输电缆，配有自动内触发、通断外触发、提前触发功能及四色绘图仪以进行测试数据和振动波形的打印，并可通过ＲＳ－２３２接口与多种微机进行通讯。可通过多种外设输出三个通道的测试与分析结果。本文结合地下和露天爆破振动测试、岩石声波波速测试和微差爆破延迟时间研究中所用岩石移动时间测试的实例，重点介绍了该测振仪的应用情况。

APPLICATION OF DSVM SERIES VIBRATION MONITOR IN BLASTING MEASUREMENT

A new type of vibration monitor which is powered by internal battery and controlled by a single chip computer is described,It can record vibration data automaticallyupon detection of any signal exceeding the present level. Signal transmission cable is not necessary, It has automatic internal,on-off external and pre-trigger models and is equipped with a 4 color plotters for vibration data printing and wave form plotting,an RS-232 interface for communication with super level computers such as IBM PC or compatible. The monitoring methods are introduced with its application examples in underground and open pit mining industry for monitoring vibration,P wave transmission speed and rock moving time.
