Abstract

The invention relates to a mud-rock flow monitoring and alarming system based on an infrasonic wave. The mud-rock flow monitoring and alarming system comprises an infrasonic sensor, a signal processing circuit, a data acquisition card and a computer. The infrasonic sensor is used for acquiring mud-rock flow infrasonic signals. The signal processing circuit is used for amplifying and filtering the mud-rock flow infrasonic signal. The signal acquisition card performs analog-to-digital conversion on the mud-rock flow infrasonic signal after signal processing and transmits the converted result to the computer. The computer utilizes an HHT method for performing time-frequency domain analysis on the signal and calculates out the power spectrum of the signal, thereby obtaining signal energy and furthermore determining a mud-rock flow disaster. The mud-rock flow monitoring and alarming system can perform real-time monitoring on occurrence of the mud-rock flow disaster and furthermore can perform alarming.

Description

technical field [0001] The invention relates to the technical field of mud-rock flow monitoring, in particular to a mud-rock flow monitoring and alarm system based on infrasonic waves. Background technique [0002] Debris flow is a common geological disaster in mountainous areas. In areas with deep valleys and steep terrain, it is formed after precipitation (including glaciers, melted snow, rainstorms, etc.) dilutes the soft soil and gravel-containing mountains. A special torrent with a large amount of solid matter such as sediment and stones. Debris flows are characterized by sudden, ferocious and rapid outbreaks, and are often accompanied by multiple destructive effects of landslides, floods and collapses. The destructive force is huge and seriously threatens water conservancy and hydropower, mines, mountainous transportation and other engineering facilities and the lives and properties of local people in mountainous areas. Safety. In recent years, large-scale debris flo...
