基于DTR技术的山体滑坡监测系统设计

Analysis of the design in landslide monitoring system based on DTR technique

山体滑坡给人们的生命财产带来巨大损失,提出了基于DTR技术的山体滑坡检测监视系统;当同轴电缆发生变形时,它的特性阻抗将发生变化,向同轴电缆发送测试电磁脉冲,当测试脉冲遇到电缆的特性阻抗发生变化,就会产生电磁波,通过测量反射电磁波的传输时间就知道发生阻抗变化的位置,即山体内部结构变化的地方,及时掌握山体的运动情况。

Landslide brings big loss to the people. This paper holds landslide monitoring system based on DTR technique. When coaxial cable has structural distortion, its characteristic resistance will change and deliver testing electromagnetic pulse to coaxial cable. When testing pulse meets the change of the characteristic resistance of the cable, electromagnetic waves are produced, testing the reflection time of the electromagnetic waves can reveal the location of the change of resistance, which is the place of inner structural change in a mountain, so that the movement condition of a mountain can be informed.
