Elevator operation control device

Abstract

The invention provides an elevator running control device, by which an elevator (2) which generates actual damages due to earthquakes is determined from a monitoring center (6) among a plurality of elevators (2) encountered with the earthquakes. The elevator running control device comprises a monitoring terminal (3) which monitors an operation state of the elevators and notifies the monitoring center (6); a P-wave detector (4a) capable of detecting P-waves; an S-wave detector (4b) capable of detecting S-waves; an earthquake controlled operation execution portion (35) which performs earthquake controlled operation only when P-waves with a level higher than a predetermined level are detected by a P-wave detecting device (31). Morever, an earthquake monitoring signal is transmitted to the monitoring center (6) only when the P-waves with a level higher than the predetermined level detected by the P-wave detecting device (31) are passed a predetermined time Tmax, and S-waves with with a level higher than the predetermined level are not detected by the S-wave detector (4b).

Description

technical field [0001] The invention relates to an elevator operation control device, which improves the safety of elevator users and the effective operation of the elevator when an earthquake occurs. Background technique [0002] In recent years, the office buildings of enterprises and government agencies have become high-rise buildings, and the high-rise buildings of individual residences such as apartments are also increasing. For people who work and live in such high-rise buildings, the chances of using elevators increase. Moreover, the chances of ordinary people other than those who work and live in high-rise buildings to use elevators in low- and middle-rise buildings have also increased. [0003] When an earthquake occurs and buildings such as tall buildings are swaying, it is dangerous to start the elevator and move the car. Therefore, for example, a seismograph (P wave detector, S wave detector, etc.) is installed in the hoistway of the elevator or in the machine r...

AI Technical Summary

Problems solved by technology

In this case, when the monitoring center receives the same earthquake detection signal from all the elevators under its jurisdiction through the communication lines at the same time, since the number of communication lines that the monitoring center can connect at the same time is limited, it is difficult for the monitoring center to obtain Each elevator receives earthquake monitoring signals

[0009] Moreover, it is difficult to identify elevators that suffered substantial damage from the earthquake

That is to say, because the number of elevators controlled during the earthquake is very large, it takes a lot of time to inspect all elevators in the earthquake area by a certain number of maintenance personnel.
