Photoelectric rockfall, landslide and collapse monitoring method, and monitoring and alarming device

Abstract

The invention relates to a photoelectric rockfall, landslide and collapse monitoring method in which a photoelectric switch or a laser device is used as a monitoring sensor, and a monitoring and alarming device which is capable of monitoring geological disasters, such as rockfall, landslide, collapse and the like, on both sides of a railway or a road at any time anywhere and automatically alarming a disaster and a rock invasion accident immediately. The monitoring device consists of a plurality of monitoring links and a monitoring alarm device; each of the monitoring links consists of an emitting column, a receiving column and an adjusting column arranged between the emitting column and the receiving column; the emitting column consists of a vertical rod 2 fixed on a base 1 and a photoelectric emitter 3 arranged on the vertical rod 2; the adjusting column consists of a vertical rod 6 fixed on a base 7, a penetrating board 5 fixed on the vertical rod 6 and an adjusting board 4 capable of moving, an adjusting board 8 and a fastening bolt 13; the receiving column consists of a vertical rod 10 fixed on a base 11 and a photoelectric receiver 9 arranged on the vertical rod 10; and the monitoring alarm device 12 is connected with the photoelectric receivers through cables.

Description

technical field [0001] The invention relates to a photoelectric monitoring method and a monitoring and alarm device for rockfall, landslides and landslides using photoelectric switches or lasers as monitoring sensors, especially a method for monitoring rockfall, landslides, landslides and other geological conditions on both sides of the line under the operating conditions of roads and railway lines. Disaster monitoring, a monitoring method and a monitoring and alarm device that can automatically alarm in time when there is a danger of disaster and a disaster line accident occurs. Background technique [0002] my country has a vast territory, complex terrain, and large climate changes. Disasters caused by climate and geology, such as falling rocks, landslides, and landslides near railways and highways, are widely distributed, of many types, and occur frequently. Take the railway as an example: According to incomplete statistics, rockfall and landslides on both sides of the ra...

AI Technical Summary

Problems solved by technology

The accuracy of the tilt sensor is limited, and it is difficult to alarm the small displacement before the landslide and landslide.

The above methods can only monitor rockfalls, landslides, and landslides, and do not have the function of monitoring and alarming accidents (earth and rock intrusion or buried traffic lines caused by rockfalls, landslides, landslides and other disasters)
