The invention is further described with reference to the following drawings and specific examples, which are not intended to be limiting.
The first embodiment is as follows:
the invention provides a control method of elevator leveling position, wherein as shown in figure 1, the method comprises the following steps:

step S3, outputting a corrected value of the leveling position of at least one car according to the first recognition result and the second recognition result;
and step S4, correcting the flat position of the car by at least one correction value before the special carrier enters and/or leaves the car.
In this embodiment, the method for obtaining the first recognition result may adopt that cameras are installed in the car and the elevator waiting hall corresponding to the outside of the car in advance, and whether a special carrier exists in the car of the current elevator and/or in the elevator waiting hall corresponding to the current elevator is recognized by the cameras, where the special carrier in this embodiment refers to a running tool with wheels, for example: handicapped people moving through a wheelchair, robots moving through a crawler, medical mobile sickbeds, carts, and the like.
As an alternative embodiment, special buttons may be installed in the car and the elevator waiting hall to obtain the first recognition result, the special buttons may be dedicated for the disabled, the medical staff for nursing the medical mobile hospital bed, the operating staff of the cart, or the robot to operate, and when the special buttons in the car and/or the elevator waiting hall are operated, the special carriers may be considered to be in the car and/or the elevator waiting hall.
Alternatively, the first recognition result may be obtained by installing buttons in the car and the lobby to receive different operation modes, including pressing the buttons consecutively a predetermined number of times, pressing a plurality of buttons in a certain order, pressing the buttons for a predetermined time, and the like. In this embodiment, the disabled, the medical staff protecting and delivering the medical mobile hospital bed, the operating staff of the cart, or the robot can operate the buttons capable of receiving the operations according to different operation modes, so as to realize the identification of the special carriers in the car and/or the elevator waiting hall.
Optionally, the first recognition result can be obtained by installing the contactless control devices in the car and the elevator waiting hall, and the disabled, the medical care personnel for nursing the medical mobile hospital bed, the operating personnel of the cart or the robot can recognize the special carrier in the car and/or the elevator waiting hall by executing the related gesture or limb action at the corresponding position of the contactless control device. Preferably, the contactless control means may be an image acquisition means.

In addition, communication devices can be arranged in the lift car and the elevator waiting hall, and the special carrier can be in communication connection with the communication devices, so that the identification of the special carrier in the lift car and/or the elevator waiting hall is realized. Preferably, the communication device may be a wireless transceiver device, such as a radio frequency card reader, and the special carrier may carry a wireless tag, such as a radio frequency tag, to implement communication connection with the wireless transceiver device.
Of course, other identification methods can be used to identify whether special carriers exist in the elevator car and/or the elevator waiting hall. It should be noted that the identification manner in the embodiment is only used for illustrating the feasibility, and the protection scope of the present application should not be limited thereby.
Further, when at least one special load is identified in the current elevator car and/or the elevator waiting hall corresponding to the current elevator, whether the current position of the special carrier is in the current elevator car and/or the elevator waiting hall corresponding to the current elevator is identified, whether an elevator operation instruction sent by the current elevator is consistent with the current position of the special carrier is judged, if so, the subsequent action of the special carrier enters the door opening interval of the current elevator, so that the special load needs to be taken out and/or into the car is judged, and it needs to be noted that the door opening interval refers to the horizontal area where the special carrier enters and exits the car, namely the area where the special carrier enters the elevator waiting hall from the car to cross or the area where the special carrier enters the car to cross from the elevator waiting hall to cross. In this embodiment, the elevator operation command can be obtained by one or more of elevator-dedicated button recognition, operation button mode recognition, voice recognition and communication recognition.
Further, when at least one special load is determined in the current elevator car and/or in a waiting elevator hall corresponding to the current elevator, and when the special load is determined to be out and/or in, the corrected value of the flat position of at least one car is output, and then the flat position of the car is corrected by the at least one corrected value when the car reaches the floor corresponding to the follow-up action of the special load, so that transportation tools such as wheelchairs, carts, medical pushchairs and robots which move through wheels can be more easily and stably out of the car.
Example two:
in the second embodiment, based on the first embodiment, in step S3, the correction value includes:
when the special load is only positioned in the elevator car, the flat position of the elevator car moves the correction value upwards so that the ground plane of the elevator car is higher than the ground plane of the elevator waiting hall; or
When the special load is only positioned in the elevator waiting hall, the leveling position of the lift car moves the correction value downwards so that the ground level of the elevator waiting hall is higher than the ground level of the lift car; or
When special loads are arranged in the car and the elevator waiting hall, the leveling position of the car moves up to correct values, and after the special loads in the car leave the car, the leveling position of the car moves down to correct values.
In this embodiment, determining the correction value for the car includes three conditions:
the first situation is that when the special load is only in the car, for example, only disabled people, medical mobile sickbeds, carts or robots which use wheelchairs to operate are in the car, and the follow-up action of at least one special load enters the door opening interval of the current elevator, the elevator can control the flat position of the current car to move upwards by a correction value so that the ground plane of the car is higher than the ground plane of the waiting hall in order to facilitate the special carriers in the car to leave the car;
the second situation is that when only the special carrier is in the waiting hall, and the follow-up action of at least one special load is recognized to enter the door opening interval of the current elevator, at the moment, the elevator can control the flat position of the elevator car to move downwards to a corrected value so that the ground level of the waiting hall is higher than the ground level of the elevator car in order to facilitate the special carrier in the waiting hall to enter the elevator car;
in the third situation, when special loads exist in the car and the elevator waiting hall, at least one special load in the car is recognized to leave the car and at least one special load in the elevator waiting hall is recognized to enter the car, at the moment, according to the principle of car space utilization, the special load in the car leaves the car first, and therefore the leveling position of the car is moved upwards by the correction value first, so that the special carrier in the car leaves the car conveniently. After the special load in the car which needs to leave the car leaves the car, the leveling position of the car is moved downwards to be corrected so that the special carrier in the waiting hall can enter the car.
In the above technical solution, the car has an initial leveling position, that is, when the leveling position of the car needs to be adjusted without using the technical solution of the present invention, the leveling position of the car can be obtained by moving the correction value upward or downward from the initial leveling position. That is, the leveling position is the initial leveling position + the correction value, which is a positive value when upward movement is required and a negative value when downward movement is required. It should be noted that there are legal restrictions on the difference between the ground level of the car and the ground level of the lobby in different areas, and therefore the adjustment range of the correction value should not exceed the range specified by the law.

and step A2, the elevator car moves upwards or downwards from the flat position according to the correction value by rotating the traction machine and enabling the output value of the encoder to be equal to the sum of the counting value and the correction value.
In the method of moving the car upward or downward from the leveling position according to the correction value in this embodiment, the leveling position of the car is first detected by an encoder provided on the hoisting machine of the current elevator. By encoder is meant a device that compiles, converts, and/or formats signals or data into a form of signals that can be communicated, transmitted, and stored. When the current elevator car stops at the target floor, the encoder card detects the counting value corresponding to the current flat position of the car, and then the flat position of the car enables the tractor to rotate according to the counting value and the condition that the special load needs to leave and/or enter the car, and the output value of the encoder is equal to the counting value plus the correction value, so that the elevator moves upwards or downwards.
Example four:
in this embodiment, on the basis of the third embodiment, as shown in fig. 3, the method for moving the car from the leveling position to the upper or lower position according to the correction value includes:
step B1, providing a magnetic graduated scale, arranging in the lift car, and reading the reading of the magnetic graduated scale through an inductor arranged in the elevator waiting hall to output an output value;
and step B2, moving the elevator car upwards or downwards to enable the reading of the magnetic graduated scale to be equal to the sum of the output value and the corrected value, so that the elevator car moves upwards or downwards from the flat position according to the corrected value.
In this embodiment, the correction value may also be set in another way, that is, a magnetic scale and a sensor electrically connected to the magnetic scale are arranged in the car in advance, and after the current car of the elevator stops at the target floor, the number indicated by the magnetic scale, that is, the output value, is read by the sensor, and then the flat position of the car moves up or down according to the count value and the condition that the special load needs to leave and/or enter the car, so that the reading of the magnetic scale is equal to the output value plus the correction value, and the car moves up or down.
