摘　　要：针对浅层地震法中传统集中式仪器存在的问题,设计了高分辨率无线分布式浅层地震仪。仪器硬件由动圈式检波器阵列、分布式采集站、控制终端、PC组成。测试结果表明,仪器实现了对微弱地震波信号的高分辨率采集,且能通过Wi Fi局域网将多达72道的数据上传至PC,并利用Lab VIEW软件进行实时显示。该仪器具有体积小、动态范围大、采集道数多等特点,特别适合在高铁、高速公路、机场等热点基础建设领域中使用。Aimed at the problems existing in the traditional centralized instrument for measurement method of superficial seismic, a wireless distributed superficial seismograph with high resolution is designed. The hardware of the instrument consists of moving - coil geophone array, distributed acquisition station, controlling terminal and PC. The test results indicate that the instrument realizes high resolution acquisition of weak seismic wave signals, and uploads as much as 72 - channel data to PC via WiFi LAN, furthermore, it proceeds real - time display by means of LabVIEW software. The instrument has prominent characteristics such as small volume ,large dynamic range, more channels of data acquisition ,and so on,which is particularly suitable for applications of high -speed railway, highway, airport and other current popular infrastructure.
