【摘要】：對(duì)典型的地震預(yù)警與烈度速報(bào)方法進(jìn)行分析,提出了基于非對(duì)稱傳感器的地震預(yù)警與烈度速報(bào)綜合用烈度儀,其由非對(duì)稱結(jié)構(gòu)的三分量傳感器和基于ARM嵌入式系統(tǒng)的專用數(shù)據(jù)采集器組成。經(jīng)過(guò)測(cè)試,該地震烈度儀的專用數(shù)據(jù)采集器具有大于107dB的動(dòng)態(tài)范圍;其非對(duì)稱三分量傳感器結(jié)構(gòu)中,所選的單分量B類傳感器的加速度誤差小于0.8%,動(dòng)態(tài)范圍大于105dB,而所選的三分量C類傳感器的加速度誤差小于5%,動(dòng)態(tài)范圍大于61dB。該地震烈度儀的各項(xiàng)指標(biāo)均滿足地震預(yù)警與烈度速報(bào)綜合應(yīng)用的各項(xiàng)技術(shù)要求,且功耗低、成本低,適合于高密度布設(shè)。
[Abstract]:Based on the analysis of typical earthquake warning and intensity reporting methods, a comprehensive intensity instrument for earthquake warning and intensity reporting based on asymmetric sensors is proposed. It consists of three-component sensors with asymmetric structure and a special data collector based on ARM embedded system. After testing, it is found that the special data collector of the seismograph has a dynamic range larger than that of 107dB, and in its asymmetrical three-component sensor structure, The acceleration error of the single component B type sensor is less than 0.8, the dynamic range is more than 105 dB, while the acceleration error of the three component C type sensor is less than 5 and the dynamic range is greater than 61 dB. All the indexes of the seismometer can meet the technical requirements of the comprehensive application of earthquake warning and intensity reporting, and the power consumption is low, the cost is low, and it is suitable for high density layout.
