Earthquake landslide hazard monitoring device

Abstract

The invention provides an earthquake landslide hazard monitoring device. The device comprises sensors, first wireless transmission devices and a data center, wherein the sensors are divided into a plurality of groups corresponding to the first wireless transmission devices; each first wireless transmission device is provided with a first storage battery which supplies power to the first wireless transmission device as well as supplies power to the sensor through a cable; each sensor is provided with a second storage battery which only supplies power to the sensors when the voltage provided by the cable is zero. According to the earthquake landslide hazard monitoring device, a low-cost and simple scheme is adopted to ensure that the sensors can independently work, and the continuous monitoring for a long time is provided; in addition, the monitoring signals of each sensor can be transmitted; therefore, the distribution range is expanded, and the monitoring and early warning range is wide.

Description

technical field [0001] The invention relates to a monitoring device in the field of earthquake research, in particular to a device that can be used for monitoring earthquake landslide disasters. Background technique [0002] Earthquake-Induced Landslide refers to the phenomenon that the rock mass or soil mass shears and slides downward for a certain distance along a gently inclined surface due to the earthquake caused by the earthquake. When a strong earthquake occurs, the landslide secondary geological disaster induced by the earthquake, especially in mountainous and hilly areas, will cause even greater economic losses and casualties than those directly caused by the earthquake. In mainland China, especially in mountainous areas with relatively complex terrain, landslides caused by earthquakes are the most common and most destructive secondary geological disasters. [0003] Earthquake landslides have the characteristics of sudden occurrence, complex mechanism, and various ...

AI Technical Summary

Problems solved by technology

[0005] However, it is usually the case that after an earthquake, some of the pre-set sensors are physically damaged due to earthquakes or landslides.

Although some of them still maintain intact functions, due to the damage of the power supply line connected to the main power supply, or the damage of the power supply line of the relay wireless transmitting equipment connected to them, this part of the sensor cannot continue to work or cannot transmit wirelessly through the relay. The device transmits the signal

The consequence will be that the on-site dynamic continuous monitoring data will be interrupted, and real-time early warning will not be realized.

After all, a large number of sensors are very expensive equipment, but the time to obtain valid data becomes very short due to power failure or failure to transmit signals, which is very uneconomical. For limited funds This result is unacceptable

Moreover, landslide secondary disasters may continue to occur after the earthquake. When the sensor does not work or cannot transmit the signal, it is impossible for relevant personnel to repair or replace the landslide site that is still very dangerous.
