Embodiment 1

[0068] A method for controlling the running speed of an elevator, referring to figure 1 , the method specifically includes the following steps:

[0069] 1100. Perform stage-by-stage processing on the speed change process during elevator operation to obtain multiple speed change stages and multiple speed change formulas.

[0070] Wherein, the above-mentioned multiple shifting formulas correspond one-to-one to the above-mentioned multiple shifting stages.

[0071] Specifically, according to the variation of the acceleration, the speed variation process during the elevator operation is processed in stages.

[0072] The above-mentioned variation of acceleration includes at least two situations of acceleration uniform increase and acceleration uniform decrease.

[0073] Such as figure 2 As shown, the speed change process in the elevator operation includes the following stages:

[0074] Pre-start stage S0: when the running speed of the elevator is instantly increased from 0 to ...

Embodiment 2

[0224] A control system for elevator running speed, refer to Figure 4 , the control system specifically includes:

[0225] The positioning device 2100 is used to obtain the real-time position of the elevator and the floor position of the floor where the elevator is expected to stop.

[0226] The data processing device 2200 is configured to obtain the remaining travel distance of the elevator according to the real-time position and the floor position.

[0227] The data processing device 2200 is also used to process the remaining travel distance according to a preset speed change model, and obtain the expected running speed of the elevator.

[0228] The control device 2300 is used to adjust the real-time running speed of the elevator according to the expected running speed.

[0229]Further, the generation process of the above variable speed model specifically includes:

[0230] According to the changing situation of the acceleration of the elevator, the speed change process ...

Embodiment 3

[0251] Embodiment 3 of the present application also provides a storage medium containing computer-executable instructions, and the computer-executable instructions are used to implement a method for controlling the running speed of an elevator when executed by a computer processor. The method includes:

[0252] The speed change process in the operation of the elevator is processed in stages to obtain a plurality of shifting stages and a plurality of shifting formulas, and the plurality of shifting formulas are in one-to-one correspondence with the plurality of shifting stages;

[0253] Determine the speed change stage of the elevator in operation, and obtain the expected running speed of the elevator according to the speed change formula corresponding to the speed change stage of the elevator;

[0254] The real-time running speed of the elevator is adjusted according to the expected running speed.

Abstract

The invention relates to the technical field of elevators, in particular to an elevator running speed control method and system and a storage medium. The method comprises the steps that staged processing is conducted on the speed change process in the elevator running process to obtain a plurality of speed change stages and a plurality of speed change formulas, wherein the speed change formulas correspond to the speed change stages one to one; the speed change stage of the elevator in operation is determined, and the expected operation speed of the elevator is obtained according to the speed change formula corresponding to the speed change stage of the elevator; and according to the expected running speed, the real-time running speed of the elevator is adjusted. The real-time running speed of the elevator can be precisely regulated and controlled, and the elevator can finish precise leveling operation.

Description

technical field [0001] The present application relates to the technical field of elevators, in particular to a method, system and storage medium for controlling the running speed of an elevator. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or less than 15° from the plumb line. [0003] During the lifting process of the elevator, due to the signal transmission delay, the change of the elevator load and the slippage of the rope used to control the elevator's lifting, etc., the elevator will not be able to accurately stop at the elevator entrance of the expected landing floor, that is, super-leveling or The case of underleveling. [0004] At this stage, how to control the elevator for precise leveling is an urgent problem for relevant enterprises to solve. Contents of the invention [0005...
