Elevator control method and device

Abstract

The invention discloses an elevator control method. The elevator control method comprises the following steps: step one, generating a conventional speed diagram; step two, selecting the conventional speed diagram as a speed diagram for elevator control; step three, controlling an elevator according to the conventional speed diagram, so that the elevator enters a conventional operation mode; step four, recording conventional operating data of the elevator for calculating the maximum speed and / or the maximum acceleration required for subsequent elevator operation; step five, calculating to obtain the maximum speed and / or the maximum acceleration according to the recorded conventional operating data of the elevator in the step four. The invention further discloses an elevator control device for realizing variable speed operation for the elevator with the method. The elevator carrying efficiency can be improved and the passenger waiting time can be shortened by regulating the maximum speed and / or the maximum acceleration of the elevator, and meanwhile the disadvantages that the capacity of an elevator driving system cannot be fully utilized and the speed diagram of the subsequent elevator operation cannot be determined in advance existing in an existing variable speed control technology can be overcome further.

Description

technical field [0001] The invention relates to an elevator control method, in particular to an elevator control method capable of changing the running speed and / or acceleration according to the actual running condition of the elevator and an elevator control device using the control method. Background technique [0002] The elevator drive system including the drive motor and electrical system is usually designed according to the maximum drive torque required by the elevator when the rated load is running at rated speed and rated acceleration, but in actual operation, the elevator in many cases requires The required actual drive torque will be less than, or even far less than its maximum drive torque (such as near the balance load), so it can be adjusted according to the actual load of the elevator by properly adjusting the maximum speed and / or maximum acceleration of the elevator. Parameters are used to fully tap the effective capacity of the elevator drive motor and electr...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to propose an elevator control method, which can improve the elevator carrying efficiency and shorten the passenger waiting time by adjusting the maximum speed and / or maximum acceleration of the elevator, and can overcome the existing variable speed control technology at the same time. The existing speed change results are conservative, the capacity of the elevator drive system cannot be fully utilized, and the subsequent running speed graph of the elevator cannot be determined in advance.
