Claims (1)
号を直接、または処理して初期微動感知に対応する処理
がとられる装置に与える地震感知装置において、３個の
初期微動感知器を互いに所定の間隔をおいて配置すると
ともに、上記３個の初期微動感知器を多数決論理回路（
２ｏｕｔｏｆ ３回路）に接続し、上記３個の感知器
のうち少なくとも２個の感知器が初期微動を感知したと
きに、上記多数決論理回路から上記装置に感知信号を与
えるように構成した地震感知装置。In an earthquake sensing device, the initial tremor of an earthquake is detected by an initial tremor sensor, and the sensing signal is sent directly or processed to a device that takes processing corresponding to the initial tremor detection. In addition to arranging them at predetermined intervals, the three initial micromotion sensors are connected to a majority logic circuit (
2 out of 3 circuit), and configured to provide a sensing signal from the majority logic circuit to the device when at least two of the three sensors detect an initial tremor. .
