摘要： PROBLEM TO BE SOLVED: To provide a seismometer capable of appropriately setting an initial value of a noise level.SOLUTION: A seismometer defines a noise level multiplied by a constant as a trigger level and determines that there is an earthquake when a signal detected by an acceleration sensor exceeds the trigger level (S20), and thus, when the noise level becomes too high, delay occurs in detection of an earthquake. Especially, when an initial value of the noise level is too high, it takes long hours for the noise level to become an adequate value and, during that period, there is a possibility that an earthquake cannot be observed. Therefore, if the noise level is too high, calculation is repeatedly performed until the noise level becomes an adequate value (S11-S12), and thereby the noise level is adequately set so that there is no possibility that an earthquake observation cannot be performed or the earthquake observation is delayed.
摘要翻译：要解决的问题：提供能够适当地设定噪声水平的初始值的地震计。解决方案：地震仪将噪声电平乘以常数作为触发电平，并确定当加速度传感器检测到的信号超过触发电平时发生地震（S20），因此当噪声电平变为太高，在发生地震时发生延误。特别地，当噪声水平的初始值过高时，噪声水平变得足够的时间需要很长时间，并且在该期间，存在无法观察到地震的可能性。因此，如果噪声电平过高，则重复执行计算，直到噪声电平成为适当值（S11-S12），从而可以适当地设定噪声电平，使得不可能进行地震观测，地震观测延误。版权所有（C）2013，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a seismometer capable of accurately distinguishing whether a detected vibration is noise or an earthquake and accurately grasping that there is a possibility of delay in detection of an earthquake, and a seismometer abnormality monitoring system for monitoring whether or not there is a possibility of the delay in detection of an earthquake by using this seismometer.SOLUTION: A seismometer defines a noise level multiplied by a constant as a trigger level and determines that there is an earthquake when a signal detected by an acceleration sensor exceeds the trigger level (S20), and thus, when the noise level becomes too high, delay occurs in detection of an earthquake. Therefore, it is monitored whether the noise level exceeds a definite threshold (S15, S17), it is determined that the delay in detection of an earthquake would occur if the noise level exceeds a predetermined threshold, and an abnormality report signal is transmitted to a central control unit 5 constituting a seismometer abnormality monitoring system (S19). Then, it is alarmed in the central control unit 5 that there is a seismometer in which the delay in detection of an earthquake possibly occurs.
