Three-dimensional sound sensitivity early warning and alarming check system

The invention provides a three-dimensional sound sensitive early warning and alarming check system and belongs to the safety technique precaution field. The invention provides an early warning and alarming check system which achieves three-dimensional detection of space, underground and areas through underground sound sensors. The invention comprises a central control host computer which processes and analyzes signal, and controls the alarm and the system. The central control host computer is connected with a plurality of area control units which demodulate area signal, control early warning and play sound. The central control host computer and the area control units are connected with a plurality of front-end control units to process and control underground sound sensor signals. A plurality of underground sound sensors connected with the front-end control units constitute monitoring subareas for solid detection of space, underground and areas. A plurality of monitoring sub-areas constitute three-dimensional solid monitoring of the entire system. The central control host computer integrates information of signals, thus giving an alarm in case of invasion, positioning and tracking targets, describing the track of the targets, monitoring sound and checking the alarm. The invention is used for guarding circumferences of critical facilities.
