Embodiment Construction

[0024] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown.

[0025] The present invention relates to a non-contact rockfall detection method using an optical sensor, comprising the steps of: preparing for rockfall detection by installing a non-contact detection sensor on a possible path of the rockfall; data.

[0026] A number of non-contact detection sensors are installed so that they are vertically or horizontally spaced from each other at regular intervals to estimate the size of the falling rock. The non-contact detection sensors are installed at any two positions on the possible path of the falling rock to estimate the speed of the falling rock.

[0027] In addition, the non-contact rockfall detection method according to the present invention includes the steps of: when the non-contact detection sensor detects an object, taking a photo of the detection a...

Abstract

A contactless falling rock detection method is provided. The contactless falling rock detection method comprises steps of: installing a contactless detection sensor on a possible path of a falling rock; and storing detection data when the contactless detection sensor detects the falling rock. According to the contactless falling rock detection method, whether the falling rock is a frame, the sizeof the falling rock, and the speed of the falling rock are determined, and since the weather is correlated with the falling rock, correlation between the weather and the falling rock can be determined via collecting weather data.

Description

technical field [0001] The present invention relates to a non-contact rockfall detection method using light sensors to determine whether a rockfall is real and its size and speed and to correlate with weather and thereby determine the correlation between weather and rockfall. 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. In about 121 places, roads near national highways were damaged by typhoon Rusa in August 2002 and chipping slopes collapsed. [0003] Although the collapse of these slopes is a natural failure, the extent of the damage can be narrowed if relevant studies and measures are prepared continuously. Many studies have been carried out to predict the collapse of slopes and to take measures before the col...
