Description

Infrasound monitoring station for monitoring geological disasters

Technical Field

The utility model belongs to the technical field of geological disaster monitoring, and particularly relates to a infrasound monitoring station for geological disaster monitoring.

Background

Geological disasters such as mountain torrent mud-rock flow often occur in mountain areas, and the safety of infrastructures and people is seriously influenced. Because the earth sound wave and the infrasonic wave are formed in the debris flow generating process, the debris flow disaster can be early warned by collecting earth sound or infrasonic signals and combining other sensor information.

Among them, the debris flow infrasonic wave has unique characteristics. The propagation speed of the infrasonic wave in the normal temperature air (about 344 m/s) is tens of times of the movement speed of the debris flow (5 m/s-20 m/s). In addition, the infrasonic wave has a wavelength much longer than that of the common sound wave due to low frequency, has little influence on reflection, refraction, diffraction and the like caused by obstacles, has the characteristics of strong penetrating power, attenuation by the viscous action of atmosphere and water, long transmission distance and the like, and can be used for detecting natural disasters which are not easy to observe in a short distance. The existing infrasonic wave signals are obtained through detection by an infrasonic wave sensor, and the infrasonic wave sensor is called an infrasonic wave sensor, namely a microphone capable of receiving infrasonic waves. There are generally a variety of transduction type sensors that can be used as infrasonic sensors, provided that there is a sufficiently low lower frequency limit. Its variety is numerous, and common ones are: capacitive, bellows, optical fiber, etc. The capacitive type sensor has small volume, high sensitivity and good frequency response, can be directly connected with a recorder or a signal real-time analog-to-digital converter, and is convenient to use.

The existing infrasonic wave sensor generally adopts a capacitive structure, namely a structure with a vibrating membrane, a polar plate, an insulator, a housing and the like, and the vibrating membrane is caused to displace relative to the polar plate to form an electric signal through air medium transmission entering from a gap of the housing. Because the geological disasters are not high in occurrence probability and are generally phenomena formed due to extreme weather, the existing equipment adopting the secondary acoustic sensor as the monitoring device is in a standby state most of the time, and once the geological disasters such as debris flow occur, the window period of reaction and forecast is extremely short, the secondary acoustic sensor is required to be always in an optimal state, and the problem that early warning cannot be timely and accurately performed due to the fact that the detection accuracy of the secondary acoustic sensor is reduced is avoided. And since such devices are usually placed in an outdoor environment, and the diaphragm must remain in communication with the outside air, the infrasonic sensor, which is in the outdoor environment for a long period of time, often requires maintenance, especially in rainy seasons or seasons in which extreme weather may occur, to confirm whether it is in an optimal operating state. Because the device is arranged in some remote mountain areas, the maintenance difficulty is high, and whether the secondary acoustic sensor keeps basic detection precision is difficult to confirm only by self detection.
