Abstract

The present invention provides a control system for abnormity or fault of elevators, if the elevator cage emergently stops and passengers are in the case, and if the distance between the emergent stop place and the elevator door of the floor is in prescribed range, the system may open the door of elevator cage from inside without waiting for maintenance technician. The system detects emergent stop place; estimates whether the elevator is in state of capable of starting if the distance between the emergent stop place and the elevator door of the floor is in prescribed range; reliving the shut of the elevator door if the estimation result is that the elevator may not start; and informing passenger in the cage to open the elevator door and escape from the elevator.

Description

technical field [0001] The invention relates to a rescue system when an elevator car stops in an emergency. Background technique [0002] When an abnormality occurs in the elevator, causing the elevator car to stop in a position other than the specified position such as the middle floor, and the elevator passengers are closed in the elevator car, it is necessary to rescue the passengers in the elevator car. Therefore, it is necessary to Grasp the emergency stop position of the elevator car. For this reason, in the prior art, a floor selector and a rotary encoder are used to detect the stop position of the elevator car. When the distance between the stop position and the nearest floor is within a specified distance When it is inside, make the elevator floor indicating device arranged in the elevator hall of the floor to indicate the position of the elevator car by lighting to flicker or light up. [0003] At this time, if the emergency stop position of the elevator car happe...
