【摘要】：对典型的地震预警与烈度速报方法进行分析,提出了基于非对称传感器的地震预警与烈度速报综合用烈度仪,其由非对称结构的三分量传感器和基于ARM嵌入式系统的专用数据采集器组成。经过测试,该地震烈度仪的专用数据采集器具有大于107dB的动态范围;其非对称三分量传感器结构中,所选的单分量B类传感器的加速度误差小于0.8%,动态范围大于105dB,而所选的三分量C类传感器的加速度误差小于5%,动态范围大于61dB。该地震烈度仪的各项指标均满足地震预警与烈度速报综合应用的各项技术要求,且功耗低、成本低,适合于高密度布设。
[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.
