基于MEMS台站的温州珊溪水库区域高密度烈度台网

High Density Seismic Network of Shanxi Reservoir Area in Wenzhou:Based on MEMS Stations

以高性能机械式力平衡加速度计为主,24位数据采集、动态范围大于或等于90dB的工业级MEMS烈度观测系统为辅,温州珊溪水库区域高密度烈度台网的建设完成使区域内强震动观测系统实现高密度、数字化、网络化覆盖,提高了该地区的地震烈度速报能力和地震观测动态范围。该台网充分利用MEMS烈度计成本低、易扩充、好管理、组网灵活方便的特点,其在浙江省地震监测中的首次成功应用将推动地震观测技术的发展。

The high performance of the mechanical force balance accelerometer,supplemented by the24 bit data acquisition,with a dynamic range more than 90 dB of the industrial MEMS intensity observation system,is used in the construction of high density network intensity Shanxi reservoir area.This makes a regional strong motion observation system to achieve high density,digital,network coverage,improves the dynamic range of seismic intensity quick report and earthquake observations in the region.The network makes full use of MEMS intensity meter,with low cost,easy expansion,good management,and network flexibility.The first successful application of seismic monitoring in our province will promote the development of seismic observation technology.
