Filed: 1994-06-10
Abstract: PURPOSE:To continue normal operation of an elevator in the case of temporary vibration by judging vibration as an earthquake only when the scale of vibration exceeds a predetermined value and a vibration continuation time exceeds a predetermined time. CONSTITUTION:A signal of a vibration detector 10 is input to compare the scale of vibration with a predetermined value 13 by a vibration comparator 11. If the scale of vibration exceeds the predetermined value 13, the vibration comparator 11 outputs a signal. On the other hand, a signal is input from the vibration detector 10 in a vibration continuation time detection circuit 12 to compare a vibration continuation time with a predetermined time t. If the vibration continuation time exceeds the predetermined time t, a vibration continuation time detector 12 outputs a signal.
