Problems solved by technology

Each method has its own advantages and disadvantages, either the monitoring accuracy is low, and it cannot monitor and alarm 24 hours a day; or the investment is large, which is not easy to promote and apply
The first three methods all need to install sensors

Embodiment Construction

[0017] Embed support (18) in place not affected by the landslide, and the rainproof and anti-theft box (17) is fixed on the support; the solar panel (12) is installed on the top, and the antenna (16) is placed outside the box, and the solar controller (16) is placed in the box 14), storage battery (15), monitoring and alarm host computer (13), rotating bracket (1); laser range finder (2) is fixed on the rotating bracket (1), if more than 2 monitoring points need to be monitored, just need 2+ swivel mounts and laser range finder. The data line of laser rangefinder (2) is connected to monitoring and alarm host computer (13), and all power supplies are connected. Select the monitoring point, in order to ensure the measurement accuracy, insert the bracket (23) into the ground to make it stable, install the reflector (22) on the bracket, see image 3 . Adjust the laser ranging direction, turn on the power, and measure the initial distance data from the reflector (22) at the monit...

Abstract

The invention discloses a landslide monitoring and alarming method and device base on laser ranging, and belongs to the technical field of disaster prevention and reduction. By means of a solar power supply system, the device is composed of a laser range finder, a three-dimension rotary support, a monitoring alarming host and a baffle board. The device is installed outside a landslide body, the baffle board is installed in the landslide body, and the distance change between the device and the baffle board is accurately measured by the laser range finder to monitor the displacement of the landslide. The device has the advantages that the monitoring mode is contactless, the measurement accuracy is high, the capacity of resisting disturbance is strong, the environmental influence is small and the device cannot be influenced by terrain, the size is small, the weight is small, the installation is flexible and convenient, and the monitoring site is not needed to be watched by people. By means of the spot check mode of sampling at regular time intervals or at any time, the high-accuracy, high-reliability, real-time, continuous, long-distance and wireless monitoring and alarming can be conducted on the landslide body automatically. The device can be widely applied to monitor and alarm mountain landslide, collapse and rockfall automatically.

Description

Technical field: [0001] The invention relates to automatic and continuous monitoring of landslide body displacement by using a laser rangefinder, in particular to a landslide monitoring and alarm method and device based on laser rangefinder. It belongs to the technical field of disaster prevention and mitigation. Background technique: [0002] Landslide is a geological phenomenon of slope rock and soil sliding along the usual shear failure surface. Landslides often cause huge losses, some even devastating disasters, to industrial and agricultural production and people's lives and property. my country is a mountainous country, the mountainous area accounts for 69.4% of the total land area of ​​our country, and the population in the mountainous area accounts for more than half of the national total population. The geological structure of mountainous areas is complex and the ecological environment is fragile; with the accelerated construction of mountainous areas, the ecologic...
