Landslide real-time monitoring and warning system

Abstract

The invention discloses a landslide real-time monitoring and warning system. The system comprises a main control node and a plurality of sensor nodes; each sensor node comprises a global positioning system (GPS) module, a vibration trigger module, a micro electro mechanical system (MEMS) accelerometer, a memory, an advanced reduced instruction-set computer (RISC) machine (ARM) processor, a wireless transmission module and a power supply module; the main control node consists of a GPS module, a wireless transmission module, a memory, an ARM processor and an alarm; the sensor nodes acquire mountain deformation parameters through the GPS modules, acquire an instantaneous abnormal underground vibration signal through the MEMS accelerometer, and send data to the main control node through the wireless transmission modules; the main control node receives the mountain deformation parameters and the instantaneous abnormal vibration data of the sensor nodes through the wireless transmission modules, comprehensively analyzes the mountain deformation parameters and the instantaneous abnormal vibration data, and sends landslide warning information to the alarm. The system can be used for monitoring the state of a mountain in real time and timely detecting premonition of landslides and has the advantages of flexible deployment and convenience for use.

Description

technical field [0001] The invention relates to the field of geological disaster monitoring, in particular to a real-time monitoring and early warning system for landslides. 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, mudslides, and subsidences occur ...

AI Technical Summary

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

[0004] The existing landslide monitoring and early warning methods and devices all need to predict the occurrence of geological disasters by observing or detecting changes in geological structures. It can give the possibility of geological disasters such as landslides and subsidences, but cannot accurately predict the time when the disaster will occur
