摘要
在此介绍一种基于STM32F437微处理器和嵌入式系统设计技术,用于超长观测距人工地震探测的微型一体化宽频带地震仪的设计原理和实现方法。在对有源差容式地震计进行了微型化和低功耗设计的基础上,使得PBS型32位宽频带流动地震仪兼具宽频带和低功耗、小体积的特点,方便野外运输、安装,还具有互联网接入能力。该仪器也可应用于天然地震宽频带流动观测,地震余震观测和水库地震观测等。该仪器在4·20四川芦山地震应急观测试验中取得了较高质量的地震观测数据,性能完全满足地震观测要求。
The design and implementation methods of a micro-integrated seismic record system based on STM32F437 MCU and embedded system technology is introduced,which is used in artificial seismic sounding projects.On the basis of low power consumption and small size design technology applied to the active feedback geophone,this broadband 32-bit seismic recorder features broadband,low power consumption and small size.Besides,it is easy to use,and possesses the characteristics of convenient transportation and high network access capability.This seismograph can also be used in natural seismic broadband mobile observation,aftershock observation and reservoir seismic observation.The high-accuracy seismological observation data was obtained by it in the emergent application in 4·20 earthquake in Lushan,Sichuan.
