Two dimensional source location system for rock fall detection by using cable sensor and mobile multimedia network

Abstract Output characteristics of cable sensor which usually used for invader detection to atomic power station and others were tested. It was found that the cable sensor could be used instead of accelerometer, when high accuracy was not required. Two kinds of experiments for two dimensional source location of impact source of rock fall. It was confirmed that impact source could be evaluated from rise time of wave forms, amplitude array of wave forms and topography pictured by using amplitudes of wave forms. It can be said that two dimensional source location system by using cable sensor and mobile multimedia network is applicable for the rock fall detection.
