基于MEMS的节点式旋转地震仪的研发及H/V谱比测试
Development of a nodal rotational seismometer with a micro-electro-mechanical system sensor and testing of H/V spectral ratios
摘要
Abstract
In response to the increasing demand for large-scale field seismic acquisition,this study developed a low-cost multifunctional nodal rotational seismometer(RBWL)with a micro-electro-mechanical system(MEMS)sensor,considering the functionality,eco-nomic feasibility,and the ease of arrangement.The RBWL employs a low-cost and low-power MEMS sensor to acquire seismic signals,involving three-component translational motions(Tx,Ty,Tz)and three-component rotational motions(Rx,Ry,Rz).To reduce the im-pacts of environmental factors on measurements,the system of the RBWL automatically records real-time information including tempera-ture and attitude while performing compensation correction on the measurement results.For real-time monitoring and data transmission at acquisition nodes,the system establishes a data transmission link integrating 4G,cloud,and client,with the measured maximum da-ta transmission rate up to 100 Mbps.The testing of H/V spectral ratios verifies the system functions and principal performance parame-ters of the RBWL and its effectiveness in engineering physical exploration.关键词
