The earthquake information transmission device which calculates the expectation arrival time of earth wave

摘要

PROBLEM TO BE SOLVED: To securely set an elevator car in the stop state before earthquake occurs, and avoid contact of the car with equipment within a hoistway and equipment failure caused by catching due to traveling during occurrence of earthquake.;SOLUTION: This elevator emergency control operation system for earthquake is provided with an earthquake information transmitting device 100 for calculating predicted arrival time of earthquake waves in accordance with the position of a registered building, based on an emergency earthquake flash report at least including the earthquake source, the hypocentral depth of the earthquake source and occurrence time; an earthquake information receiving device 200 installed in the building, receiving the predicted arrival time via the Internet 1, and calculating earthquake arrival allowable time that is time until the earthquake waves reach the building, based on the predicted arrival time; and an elevator control board 300 for performing operation to stop the elevator car 600 on an evacuation floor, when the elevator car 600 travels to the direction of the evacuation floor, car call to the evacuation floor is registered, and stop time on the evacuation floor is shorter than the earthquake arrival allowable time.;COPYRIGHT: (C)2007,JPO&INPIT
