Abstract

The invention relates to a natural-disaster infrasonic wave monitoring system. The system comprises monitoring stations and a center data server. The plurality of monitoring stations are connected to the center data server so as to form a monitoring network. One monitoring station comprises an infrasonic wave sensor, a meteorological three-element sensor, a fixed-point GPS measuring instrument, a data acquisition transmission module and a wind noise reduction pipeline. The infrasonic wave sensor is installed in the wind noise reduction pipeline. The infrasonic wave sensor collects infrasonic wave data. The meteorological three-element sensor collects meteorological data including a temperature, a rainfall and a wind speed. The fixed-point GPS measuring instrument measures ionospheric disturbance. The center data server comprises a data storage server, an infrasound signal analysis module and a natural disaster determination module. The infrasound signal analysis module analyzes a characteristic of infrasonic wave data and transmits a result to the natural disaster determination module. Based on the characteristic of the infrasonic wave data, the natural disaster determination module combines GPS data and meteorological three-element data to determine a natural disaster condition.

Description

technical field [0001] The invention relates to the field of infrasound monitoring, in particular to a natural disaster infrasonic monitoring system. Background technique [0002] In the natural state, there are always various infrasound waves in the air, including strong winds, typhoons, rainstorms, mountain torrents, mudslides, meteor showers, avalanches, ground subsidence, bolides, volcanoes, earthquakes, tsunamis and other natural events are the main sources of natural infrasound waves. The infrasound waves radiated into the air during the gestation and occurrence of these natural events have certain characteristics, mainly manifested in differences in the frequency range, and the amplitude of the generated infrasound waves often has a corresponding relationship with the activity intensity of the above events. Typically, at 9:00 am on February 15, 2013, the Russian fireball entered the atmosphere due to friction with the air to generate heat and shock waves, and the wave...
