Description

An elevator control device without an up and down call button

technical field

The utility model belongs to the technical field of elevator control, in particular to an elevator control device without an up and down call button.

Background technique

Elevators are indispensable vertical transportation equipment in modern multi-storey and high-rise buildings, and have become an indispensable part of people's daily life. The elevator includes traction system, guide system, door system, car, weight balance system, electric drive system, electrical control system and safety protection system. Among them, the function of the electrical control system is to manipulate and control the operation of the elevator. Usually It is composed of operating device, position display device, control panel, leveling device and layer selector, etc. The floor selector can play the role of indicating and feedbacking the position of the car, determining the running direction, and sending out acceleration and deceleration signals. In the early elevators, the driver generally processed the signals and issued instructions. This control is called signal control; later it evolved into responding and running according to the prescribed procedures through logic circuits. This control is called collective selection control. The collective selective control elevator is an automatic elevator operated by passengers themselves or sometimes by a full-time driver. The elevator has an up call button on the bottom floor, a down call button on the top floor, and two up and down call buttons on the other middle floors. The operation box in the car is provided with command buttons equal to the number of stops. When the passenger entering the car presses the command button, the command signal is registered, and when the passenger waiting outside the car presses the call button, the call signal is also registered, and the elevator can memorize several calls inside and outside the car at the same time Signal. During the upward process, the elevator stops one by one according to the registered command signal and upward call signal, until the highest floor station with these signal registrations or the lowest floor with downward call registration, and then reversely press the registered command signal and The down call signal stops one by one, and the elevator automatically decelerates, levels and opens the door every time it stops. After all the registration instructions are served, the elevator will stop at the last floor and close the door for standby.

Passengers call the elevator by operating the external call button of each floor station. However, in the daily use of the elevator, the following "disruptive call" situation is often encountered: some passengers press the up or down call at the floor station After pressing the button, walk away due to various reasons; some passengers improperly press all the call buttons in the up and down directions, and when the passenger takes the elevator up or down to leave, the call command in the other direction still exists. There is no one waiting for the elevator with "disruptive call" to stop at the designated floor according to the external call instruction, which will reduce the working efficiency of the elevator, consume time and electricity, increase the wear and tear of the elevator, and delay the time of normal passengers. In addition, if a passenger needs to take the elevator while the elevator is closing the door, it will often happen that the passenger is too far away from the elevator hall door and cannot press the call button in time to wait for the passenger. This situation will also waste the time of the passenger. And cause the waste of energy.

In view of the above-mentioned prior art, it is necessary to improve the structure of the existing elevator control device. For this reason, the applicant has made a useful design, and the technical solution to be introduced below is produced under this background.
