Embodiment Construction

[0014] Embodiments of the present invention will be described below with reference to the drawings.

[0015] Fig. 1 is a diagram showing the overall configuration of an elevator recovery system according to an embodiment of the present invention.

[0016] In the building 11, an elevator hoistway 12 is installed, and one elevator 13 is installed therein. The elevator 13 is composed of a car 14 , a counterweight 15 , a rope 16 and a hoist 17 .

[0017] The car 14 carries users and moves between floors of the building 11 , and the counterweight 15 has substantially the same weight as the car 14 . Cable 16 rolls are hung on the winch 17, and its one end connects car 14, and the other end connects counterweight 15. Accordingly, as the hoist 17 is driven, the car 14 moves in a bucket-like manner in a direction opposite to the counterweight 15 via the rope 16 . At this time, pulse signals corresponding to the rotational speed of the hoist 17 are sequentially output from the pulse ...

Abstract

The invention relates to an elevator restoration system. The stopping elevator caused by earthquake is early recovered without on-site busywork of troubleshooter. The running state of the car and running stop signal of the elevator are sent together to remote supervision centre when the earthquake detector acts and the elevator stops to running due to earthquake. In the remote supervision centre, on receiving the running stop signal of the elevator, the information associated with running state of the car is obtained and displayed in the monitoring frame(stepB11~B13). On the monitoring frame, if the car of a building is on the undermost floor and on the stand-by state, the earthquake detector on the elevator of the building is remotely reset and the running of the elevator is restored (stepB14~B14). Thus, the stopping elevator caused by earthquake is early recovered without on-site busywork of troubleshooter.

Description

technical field [0001] The present invention relates to an elevator recovery system for restoring the operation of an elevator when an earthquake occurs. Background technique [0002] In recent years, elevators have become indispensable as vertical means of transportation along with high-rise buildings and the like. Moreover, on the other hand, the problem of the safety of the elevator in the case of an earthquake has been pointed out. [0003] Generally, an earthquake detector is installed in an elevator, and when shaking of an earthquake with an intensity of 4 or higher is detected by the earthquake detector, the operation of the elevator is usually forcibly stopped. [0004] However, when the earthquake detector is once activated due to the occurrence of an earthquake, even if there is no special obstacle to the operation, the operation of the elevator can only be resumed only if the maintenance personnel reset the earthquake detector at its site. Therefore, there is a ...
