Elevator car position display device

Abstract

The invention provides a car position display device of an elevator. An elevator car position display device is provided with: a speed determination unit that determines a speed level on the basis ofan elevator car speed; an image data storage unit that stores image data having each floor as display content at an image level corresponding to the speed level; a display data determination unit thatdetermines display data to be displayed on the display on the basis of the car position information and the speed level, reads the matching image data from the image data storage unit, and executes the required data processing; and a display unit that displays the image data after the data processing on a display. In a car position display device, image data differs in display processing time ofcar position display in accordance with an image level (which can be replaced by a speed level), and the display processing time of car position display is shorter in a case of a high speed level thanin a case of a low speed level.

Description

technical field [0001] The present invention relates to an elevator car position display device, and is suitable for use in an elevator car position display device capable of displaying the position of a moving car inside the elevator car. Background technique [0002] Conventionally, on a display panel or the like in an elevator car, the current car position is displayed based on car position information. However, especially in high-speed elevators, when the car moves floors faster than the update cycle of the car position information, the car position information will skip intermediate floors, and sometimes the car position information on the display panel will appear. The floor displayed by the car position is skipped. As a result, there is a problem of giving an unfriendly impression or a sense of incongruity to passengers. [0003] To address such a problem, for example, Patent Document 1 discloses a car position display device that supplementally displays the missing...

AI Technical Summary

Problems solved by technology

As a result, when the car moves at high speed in the existing elevator, the time for the car to pass the floor is faster than the processing time required for displaying the position of the car passing the floor, so the car cannot be moved to the floor. Car position display, there is a problem that the floor displayed by the car position is skipped

[0008] In addition, it is considered that the above-mentioned floor skip problem of the car position display is difficult to eliminate in the car position display device disclosed in Patent Document 1.

For example, even if the car position display is to be supplemented on the passing floor where floor skipping occurs, the result may not be completely displayed due to the excessive processing time for the supplementary display.

In addition, since it is assumed that even if the processing time for the supplementary display is accommodated within the passing time, the display time of the supplementary display can only be ensured for a very short time, so passengers cannot fully recognize the displayed content, which may give passengers a sense of discomfort
