Ultrasonic-based landslide displacement and slip monitoring system and measurement method thereof

Abstract

The invention discloses an ultrasonic-based landslide displacement and slip monitoring system and a measurement method thereof. The landslide displacement and slip monitoring system comprises an ultrasonic wave reflection device, a depression angle remote camera and an upper solar photovoltaic cell for supplying power to the ultrasonic wave reflection device and the depression angle remote camera,wherein the ultrasonic wave reflection device, the depression angle remote camera and the upper solar photovoltaic cell are mounted on the slope top; the slope bottom is equipped with an ultrasonic ranging device, an elevation remote camera and a signal receiving device; the system also comprises a pressure sensor in the potential landslide area of a mountain body and used for acquiring signals and transmitting the signals to a monitoring computer of the monitoring center, and an optical cable extending to the bottom of the slope laid from the top of the slope, wherein the optical cable is flat, and the outer layer of the optical cable is a fluorescent layer, and the fluorescent layer is exposed out of a landslide main cut-off arm to serve as an ultrasonic ranging device detection point when landslide occurs; and the optical cable is connected with the electric devices and transmits the overlooking landslide information image, the distance measuring information and the elevation landslide image to the monitoring computer of the monitoring center, and the monitoring computer controls an alarm to give out alarm information. Real-time camera shooting can be carried out on the landslide, an early warning function is achieved, and the vertical displacement and the horizontal displacement of the landslide are measured in real time after the landslide.

Description

Technical field: [0001] The invention relates to the field of geological disaster monitoring, in particular to an ultrasonic-based landslide displacement monitoring system and a measurement method thereof. Background technique: [0002] In recent years, geological disasters such as earthquakes, landslides, and debris flows have occurred frequently at home and abroad, especially in my country. Due to the excessive development of resources, the natural environment has deteriorated seriously, and various geological disasters have caused great harm to people's lives and property safety. . In addition, with the continuous construction of infrastructure such as large-scale hydropower stations, reservoirs, highways, and railway projects, destructive disasters such as landslides, embankment bursts, and collapses have also seriously affected the safety and life of these infrastructures. According to incomplete statistics, tens of thousands of geological disasters such as landslides, ...

Problems solved by technology

However, these methods have problems such as large monitoring equipment and the need for professional operation. They can only monitor a few important areas and cannot be extended to areas with potential safety hazards. It is difficult to meet the needs of villages, enterprises and individuals for geological disaster monitoring and early warning. need
