摘要:
 震前地声是一种重要的地震前兆信息,对其进行有效的监测有助于对地震孕育机制研究和地震预报工作. 一种适用于大地震临震监测的地声监测系统,通过深井放置在基岩附近绕过地表的滤波,直接监测来自地下的地震前兆地声信息. 文中对该系统中的地声传感单元的传感器特性及其接口电路的设计进行了介绍. 传感器组包括三种传感器—压电薄膜传感器、MEMS麦克风和压电陶瓷传感器,分别用以监测震前地声信号中的次声波信号、可听波信号以及超声波信号;传感接口电路用于将传感器采集到的信号处理后由串行通信控制模块上传.
Abstract:
 Geo-sound is a kind of very important precursor signal before earthquake. To make an effective monitoring on geo-sound pre-cursory is of certain significance for earthquake mechanism and imminent earthquake prediction. A geo-sound precursory monitoring sys-tem for violent earthquake is proposed. It is placed near the bedrock through a deep hole which can eliminate human disturbance from sur-face and difference of soil structure in different regions. In this paper,the geo-sound sensors chosen and their interface circuits are intro-duced in detail. There are piezoelectric film sensor,MEMS microphones and piezoelectric sensors to sense infrasonic wave,sonic wave and ultrasonic. The interface circuits implement the function of transfer sensor signal to other terminal through serial communication proto-col.
