The invention discloses a
landslide monitoring and alarming method and device based on
laser ranging. The
landslide monitoring and alarming device is composed of a
laser range finder, a rotary support, a monitoring and alarming host, a beeper, a data recorder, a solar panel, a
solar controller and a storage battery. The
landslide monitoring and alarming device and method have the advantages that a non-contact monitoring mode is realized, measurement accuracy is high, the anti-jamming capability is high, the influence from the environment is small, no influence from various terrains (particularly certain areas difficult for constructors to reach) exists, the device is small in size, light in weight and flexible and convenient to install, and no one needs to attend a
monitoring site. A fixed sampling time interval or a method of spot check at any time is used, and therefore high-accuracy, high-reliability, real-time, continuous, remote and
wireless monitoring and alarming are conducted automatically on multiple monitoring points. The landslide monitoring and alarming method and device based on
laser ranging can be widely applied to automatic monitoring and alarming in the fields of landslides, collapse, rock falls and the like.
