Problems solved by technology

For example, video monitoring technology, that is, by setting up video monitoring points in the debris flow channel to provide real-time feedback on whether the debris flow has occurred and the scale of the occurrence, but this method cannot provide clear and effective images in bad weather conditions such as rainy nights, and it is very easy to cause disaster information. False report
When a debris flow occurs, obvious vibration waves (also called ground sound) will be generated on the surface, and sound waves will be formed in the air at the same time. Therefore, the occurrence of debris flow can be warned by monitoring the ground sound (or infrasound) signal, but due to the rapid attenuation of surface vibration At present, the geoacoustic monitors commonly used can only monitor the vibration signals of debris flows passing through the monitoring points, which cannot meet the requirements of early warning

Embodiment 1

[0070] Such as Figure 1 ~ Figure 2 As shown, a mountain disaster monitoring terminal is processed.

[0071] figure 1 It is a schematic diagram of the external structure of the mountain disaster monitoring terminal. The mountain disaster monitoring terminal includes a rainfall sensor 1 and a data signal processing component 2. The outermost part of the data signal processing component 2 is a protection box 21, and inside the protection box 21 are other electronic components of the data signal processing component 2. The appearance of the mountain disaster monitoring terminal is an up-and-down structure, and the rain sensor 1 is fixedly connected to the outer surface of the upper part of the protection box 21 .

Embodiment 2

[0075] Such as image 3 As shown, a mountain disaster monitoring terminal is processed. The same parts as the first embodiment will not be repeated, and the difference lies in the addition of a ground motion transmission member 3 .

[0076] image 3 It is a schematic diagram of the external structure of the mountain disaster monitoring terminal (rod-shaped earthquake motion transmission part). The mountain disaster monitoring terminal also includes an earthquake transmission part 3 connected to the outer surface of the protection box 21 . The product as a whole has an upper, middle and lower structure. The rain sensor 1 is fixed above the outside of the protection box 21, and the seismic transmission part 3 is fixed below the outside of the protection box 21. Earthquake transmission part 3 is a solid bar-shaped part, which is detachably statically connected with the lower surface of protection box 21 .

Embodiment 3

[0078] Such as Figure 4 ~ Figure 5c As shown, a mountain disaster monitoring terminal is processed. Its similarity with Embodiment 2 will not be repeated, and its difference lies in the structure of the seismic vibration transmission part.

[0079] Figure 4 It is a schematic diagram of the external structure of the mountain disaster monitoring terminal (radiation symmetrical conical earthquake motion transmission part). The earthquake transmission part 3 is a radially symmetrical conical part, the big end is fixedly connected with the bottom surface of the protection box 21, and the small end is a free end. The seismic transmission part 3 is a solid metal part, and is detachably statically connected with the lower surface of the protection box 21 .

Abstract

The invention discloses a mountain disaster monitoring terminal, a mountain disaster self-adaptive monitoring and early warning method and a debris flow / landslide self-adaptive monitoring and early warning method. The mountain disaster monitoring terminal comprises a rainfall sensor and a data signal processing assembly, and further comprises a seismic oscillation transmission part and is of an upper-middle-lower structure. The mountain disaster self-adaptive monitoring and early warning method comprises the steps: firstly, selecting a monitoring site according to a mountain terrain, installing the monitoring terminal, and when a rainfall monitoring assembly of the monitoring terminal recognizes that the environmental rainfall reaches a preset rainfall threshold value, a power supply assembly is triggered to start a seismic oscillation signal detection assembly to start to collect a seismic oscillation signal; and if the seismic oscillation signal detection assembly detects that the main frequency of the seismic oscillation signal further accords with a preset frequency range threshold condition, the data are stored, a seismic oscillation signal interpretation program is executed, and then an interpretation result is sent to a receiving terminal. According to the debris flow / landslide self-adaptive monitoring and early warning method, a debris flow / landslide body motion characteristic seismic oscillation signal interpretation program is executed to measure and calculate the disaster speed and scale.

Description

technical field [0001] The invention relates to a monitoring terminal for mountain disasters and a method for monitoring and early warning of debris flow / landslides, in particular to a device and method for non-contact monitoring and early warning of mountain disasters including debris flow by using ground motion signals. It belongs to the field of signal analysis and processing technology, geological disaster monitoring and early warning technology. Background technique [0002] Debris flow, landslide and rockfall are the three main types of mountain disasters. The current mountain disaster monitoring and early warning system can be divided into two types: pre-warning system and event-based early warning system. Taking debris flow monitoring and early warning as an example, the pre-warning system type uses monitoring hydrological data as the early warning conditions, such as cumulative rainfall and soil water content (pore water pressure), and sends out early warning infor...
