Embodiment Construction

[0027] Hereinafter, the content of the present invention will be described more fully and completely with reference to the accompanying drawings, which show preferred embodiments of the present invention.

[0028] A non-contact rockfall detection device using an optical sensor of the present invention includes: hardware components including a sensor unit, a data processing unit 10, and a power supply unit; and software components including an analysis program for analyzing data measured by the sensor unit , and a database 12 for managing said measured data and analyzed data.

[0029] The sensor unit includes: a non-contact sensor, a camera 71, a temperature and humidity sensor 72, and a rain gauge 73 to collect data to determine whether a rockfall 300 has actually occurred, the size and speed of the rockfall 300, temperature, humidity, and precipitation.

[0030] The selection of the non-contact sensor should consider the size of the slope to be detected, the accuracy, the min...

Abstract

The invention relates to a rock fall detection device, especially relates to a non-contact rock fall detection device using an optical sensor, comprising a non-contact detection sensor. The non-contact rock fall detection device can determined whether it is a falling rock or not and determines the size and speed of the rock fall. Through collecting weather data which is associated with the rock fall, the relation between the whether and the rock fall is established.

Description

technical field [0001] The present invention relates to a non-contact rockfall detection device using an optical sensor, thereby determining whether a rockfall has actually occurred, the size and speed of the rockfall; and establishing a relationship between the rockfall and the weather by associating the rockfall with the weather. Background technique [0002] In Korea, many slopes are built by roads and railways to connect the whole country. When climatic disasters such as heavy rain, typhoon / storm, and earthquake occur after construction, the slope collapses completely or debris falls, causing loss of life and property in many cases. During Typhoon Rusa in August 2002, roads near national highways were damaged, and cutting slopes collapsed, affecting about 121 locations. [0003] The collapse of these slopes is the result of natural forces, but the extent and scope of these damages can be minimized if the relevant research and related measures are carried out continuousl...
