Non-contact landslide hazard monitoring system and method

Abstract

The invention discloses a non-contact landslide hazard monitoring system, which comprises a laser radar scanner, a video check device and a monitoring center processing platform, wherein the laser radar scanner, the video check device and the monitoring center processing platform are connected with a monitoring processing host. The laser radar scanner is used for obtaining distance data of distance from each point in a landslide monitoring region to the laser radar scanner; the monitoring processing host is used for receiving the distance data collected by the laser radar scanner, obtaining an over-limit detection result and sending the over-limit detection result to the monitoring center processing platform; and when the monitoring center processing platform judges that the over-limit detection result surpasses the data threshold, the monitoring processing host triggers the video check device to collect videos to carry out recheck. The non-contact landslide hazard monitoring system monitors the whole landslide monitoring region by utilizing the three-dimensional scanning technique, so that the landslide geological disaster can be monitored accurately; and through linkage with the video check device, the monitoring system realizes an early warning-alarm-check processing mechanism. The invention also discloses a corresponding monitoring method.

Description

Technical field [0001] The invention relates to a landslide disaster monitoring system, in particular to a non-contact landslide disaster monitoring system. The invention also relates to a monitoring method realized by using the above landslide disaster monitoring system, and belongs to the field of geological disaster monitoring. Background technique [0002] A landslide is an overall sliding failure phenomenon that occurs when part of the rock and soil forming the slope is sheared along a certain weak surface inside the slope under certain natural and geological conditions. In recent years, accidents caused by landslide disasters have occurred frequently, seriously threatening people's lives and property. [0003] There are mainly three types of existing landslide monitoring technologies: 1) traditional landslide monitoring technology; 2) distributed optical fiber monitoring technology; 3) GNSS displacement monitoring technology. The above three monitoring technologies are all c...

Problems solved by technology

But at the same time, it also has the following disadvantages: contact measurement, troublesome construction, greatly affected by factors such as temperature and optical fiber aging, high false alarm rate, and high cost

GNSS displacement monitoring technology has the advantages of high monitoring accuracy and good effect; however, it still only monitors points on the slope, not all-round monitoring; and the construction of the entire monitoring technology is difficult, long period and high cost
