Elevator

Abstract

The invention relates to an elevator. The elevator comprises elevator doors (102), calling buttons (130) arranged on elevator lobbies and an elevator control device (110), wherein the elevator control device (110) is provided with an elevator door control part (116) and a passenger detecting part (114); the elevator door control parts transmits an elevator door control command, and the passenger detecting part detects whether the elevator has a passenger or not according to the signal of a passenger detecting device (104). The elevator uses the button lamp of the calling buttons as an advance notice device, and the flicking, on and off of the button lamp is used as the advance notice signal. Under the control of the elevator door control part, the advance notice device transmits the advance notice signal in a time period from the opening of the elevator doors to the closing of the elevator doors and changes the advance notice signal along with time so as to notify the remaining time of door closing in advance. By the arrangement, the elevator has the advantages that the remaining time of door closing can be effectively notified in advance while the existing structure of the elevator is unchanged, and the passenger can be prevented from being collided with the elevator doors.

Description

technical field [0001] The invention relates to an elevator, which includes an elevator door, a call button and an elevator control device. Background technique [0002] The general elevator opens the elevator door automatically when the car arrives at the calling floor. If no passenger operates the door opening button, the elevator automatically closes the elevator door after a predetermined door opening time. However, the passengers at the landing do not know how long the set door opening time is, and when the elevator doors will be closed, which often causes passengers to bump into the elevator doors that start to close. [0003] Japanese Patent Publication No. 2002-179370 discloses a door closing warning device for an elevator. The device is to issue a door-closing notice to passengers by setting a luminous body on the car door or car threshold, or to set a time display near the landing door and in the car to show passengers the remaining time from door closing with a c...

Problems solved by technology

However, no matter which way is selected, this technology needs to add illuminants and illuminant control devices, or add devices such as time displays on the elevator, which will greatly increase the cost of the elevator.
