Problems solved by technology

[0003] At this stage, after the elevator runs to the destination floor, the ground plane of the car will not be on the same level as the ground plane of the waiting hall on the floor where the elevator car stops due to the problem of car leveling accuracy. Disabled people, medical mobile beds, carts, or robots running on tracks or wheels will cause certain resistance and impact on the car when they need to enter and exit the car, making it inconvenient for special loads in the car to leave the car, and those located in and out of the car. The special load in the elevator hall corresponding to the car enters the car. Therefore, the problem that the above-mentioned special load is inconvenient to enter and exit the car has become a difficult problem to be solved urgently by those skilled in the art.

Embodiment 1

[0043] The present invention provides a method for controlling the leveling position of an elevator, wherein, as figure 1 Shown, including:

[0044] Step S1: Identify at least one special load in the car of the current elevator and / or in the waiting hall corresponding to the current elevator to output a first identification result;

[0045] Step S2: Identify the follow-up action of the special carrier to output a second identification result;

[0046] Step S3: Output the correction value of the leveling position of at least one car according to the first recognition result and the second recognition result;

[0047] Step S4: Correct the leveling position of the car with at least one correction value before the special carrier enters and / or leaves the car.

[0048] In this embodiment, the method for obtaining the first recognition result may be to install a camera in the waiting hall corresponding to the inside of the car and outside the car in advance, and to recognize the inside of the...

Embodiment 2

[0058] In the second embodiment, on the basis of the foregoing embodiment 1, in step S3, the correction value includes:

[0059] When the special load is only in the car, the leveling position of the car is moved upward by the correction value so that the ground level of the car is higher than the ground level of the waiting hall; or

[0060] When the special load is only in the waiting hall, the leveling position of the car is moved downward by the correction value so that the ground level of the waiting hall is higher than the ground level of the car; or

[0061] When there is a special load in the car and in the waiting hall, the leveling position of the car will first move upward to correct the value. After the special load in the car leaves the car, the leveling position of the car will move downward to correct. value.

[0062] In this embodiment, determining the correction value of the car includes three conditions:

[0063] The first situation is when the special load is only lo...

Embodiment 3

[0068] This embodiment is based on the second embodiment above, such as image 3 As shown, the methods of moving the car up or down from the leveling position according to the correction value include:

[0069] Step A1: Provide an encoder, which is set on the traction machine of the current elevator to detect the leveling position of the car, and output a count value;

[0070] Step A2, by rotating the traction machine and making the output value of the encoder equal to the sum of the count value and the correction value, so as to realize that the car moves up or down according to the correction value from the leveling position.

[0071] In the method of moving the car up or down from the leveling position according to the correction value in this embodiment, the leveling position of the car is first detected by an encoder set on the traction machine of the current elevator. The so-called encoder refers to a device that compiles and converts signals or data into signal forms that can ...

Abstract

The invention relates to the technical field of elevators, in particular to an elevator levelling position control method and system. The control method comprises the steps of S1, recognizing at leastone special load in a lift car of a current elevator and / or an elevator waiting hall corresponding to the current elevator so as to output a first recognition result; S2, recognizing subsequent actions of the special carriers so as to output a second recognition result; S3, outputting at least one correction value of the levelling positions of the lift car according to the first recognition result and the second recognition result; and S4, correcting the levelling positions of the lift car through the at least one correction value when the lift car arrives at the floors corresponding to the subsequent actions of the special loads. According to the technical scheme, the elevator levelling position control method and system have the beneficial effects that the levelling positions of the lift car are corrected so that transportation tools with wheels, such as wheelchairs, carts, medical pushing beds and robots, can more easily and more stably enter and leave the lift car.

Description

Technical field [0001] The invention relates to the technical field of elevators, in particular to a control method and a control system of elevator leveling position. Background technique [0002] With the continuous increase of the urban population and the rapid progress of urban construction, high-rise buildings have become the mainstay of contemporary urban architecture, and the application of elevators has become more and more extensive. Elevator leveling refers to the car door opening after the elevator runs normally to the target floor and stops, and the leveling position refers to the position of the car when the car door is opened. [0003] At this stage, after the elevator runs to the destination floor, due to the leveling accuracy of the car, the ground plane of the car and the lobby of the elevator car parking floor are not on the same level. At this time, if there is a wheelchair moving Disabled people, medical mobile beds, carts or robots running on crawlers or wheel...
