NON CONTACT ROCK FALL DETECTION APPARATUS USING PHOTO SENSORS

摘要

PURPOSE: A contactless falling rock sensing device is provided to recognize the correlation between the weather and the falling rock. CONSTITUTION: A sensor part comprises a contactless sensor, a camera(71), a temperature and humidity sensor(72), and a rain gauge system(73). The sensor part collects a falling rock, the size and speed of the rock, temperature, humidity, and rainfall. The contactless sensor is an optical sensor. The camera is installed in the vicinity of the optical sensor in order to determine whether a falling rock exists. The sensor part measures data in order to obtain the correlation between the falling rock and the weather.
