Embodiment Construction

[0016] like figure 2 As shown, the system consists of a master node and multiple sensor nodes. The master control node is deployed in a structurally stable area, providing an observation base and serving as a data processing center. The sensor nodes are deployed in potential landslide areas to monitor the deformation of the mountain surface and the abnormal signal of underground vibration. Data and control information are transmitted between sensor nodes and master control nodes through wireless transmission (such as figure 1 shown).

[0017] The circuit block diagram of the sensor node is as follows: image 3 As shown, it includes GPS module, vibration trigger, MEMS accelerometer, memory, ARM processor, wireless transmission module, power supply module, GPS satellite antenna and wireless transceiver antenna. Its physical structure is as Figure 4 As shown, it consists of metal probe 1, base 2, MEMS accelerometer 3, vibration trigger 4, sensor board 5, processor board 6,...

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 ...
