Description

Technical Field

[0001] The present invention belongs to the technical field of elevator maintenance, and in particular relates to a method, system, device and storage medium for automatic correction of the leveling position of an elevator car. Background Art

[0002] With the development of elevator technology, elevators have become an indispensable part of people's lives. Their convenience and safety directly affect people. Therefore, daily maintenance of elevators has become particularly important. At present, elevator maintenance often requires verification of the elevator car's leveling position. Because when the elevator car's leveling position deviates, it often causes inconvenience to people entering and exiting the elevator, and may even cause personal safety issues. Therefore, the correction of the elevator car's leveling position is an important part of elevator maintenance.

[0003] Currently, maintenance personnel mostly use floor self-learning to calibrate the leveling position of the elevator car. Floor self-learning mainly involves controlling the elevator car to run slowly from the bottom position to the top position during elevator commissioning. During operation, the relative position of each floor is identified by detecting the action signal of the leveling plug plate on each floor, thereby achieving the leveling position correction effect of the elevator car.

[0004] However, during the long-term use of the elevator, the elevator's wire rope will elongate to a certain extent with continuous use. The elongation of the wire rope will cause the wire rope diameter to become thinner. At the same time, the rope groove of the elevator traction wheel will wear to a certain extent during long-term use. The two factors will cause the engagement depth of the elevator wire rope on the traction wheel rope groove to increase. After the engagement depth increases, the effective diameter of the traction wheel becomes smaller, resulting in the actual displacement of the wire rope when the traction wheel rotates one circle. This causes the actual position to deviate from the preset position when the elevator continues to operate according to the floor spacing pulses in the previous floor self-learning, resulting in inaccurate leveling. Although floor self-learning can solve this problem, frequent use of floor self-learning for the elevator requires a lot of manpower costs, which increases the maintenance cost of the elevator and prolongs the maintenance time of the elevator, affecting user use. Summary of the Invention

[0005] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a method for automatic correction of the elevator car leveling position. The method introduces a pulse variation coefficient as a correction parameter for the elevator car leveling position, and updates the number of pulses of the original floor of the elevator by calculating the average pulse variation coefficient within the elevator car cycle, thereby realizing automatic correction of the elevator car leveling position and effectively reducing the maintenance cost of the elevator.

[0042] The present invention will be further described below with reference to the accompanying drawings and examples.

[0043] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0044] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0045] Example 1

[0046] like Figure 1 As shown, this embodiment provides a method for automatically correcting the leveling position of an elevator car, comprising the following steps:

[0047] S1. Obtain the initial operating parameters of the elevator to be verified, perform floor self-learning on the elevator to be verified based on the initial operating parameters, and obtain initial pulse parameters corresponding to the elevator to be verified; the initial pulse parameters include floor height pulse, initial leveling plate pulse, and initial interval pulse;

[0048] The initial operating parameters include the rated frequency of the car motor, the rated speed of the car motor, the rated operating speed of the elevator, the number of encoder pulses and the length of the leveling plate.

[0049] Specifically, in this embodiment, the heights of each floor of the building corresponding to the elevator to be checked are the same.

[0050] Specifically, in this embodiment, the verification running speed is 0.25 m / s.

[0051] The initial interval pulse is expressed as follows:

[0052] N HD3 =NND1

[0053] Among them, N HD3 is the initial interval pulse, N is the floor height pulse obtained during floor self-learning, N D1 It is the initial leveling board pulse obtained during floor self-learning.

[0054] S2. Control the elevator to be verified to ascend at a constant speed from the current floor at the verification speed. When the elevator to be verified passes the leveling plate position of the previous floor, stop the elevator and obtain the current leveling plate pulse and the current interval pulse.

[0055] This setting is because the leveling plate is a common sheet metal component shipped with elevators. It is typically fixed in length, 250mm, and is installed at the leveling position on each floor. The effective coverage area of ​​the leveling plate is the door area. When the elevator travels upward to the leveling position of the previous floor, the leveling sensor installed on the car is located in the center of the leveling plate. At this point, the elevator car sill is flush with the floor door sill. The leveling plate blocks the photoelectric signal from the leveling sensor. Therefore, the elevator can only detect the current leveling plate pulse of the previous floor and, therefore, the current interval pulse, after traveling upward and passing the leveling plate position of the previous floor.

[0056] S3. Calculate a current leveling board pulse coefficient and a current interval pulse coefficient based on the current leveling board pulse and the current interval pulse in combination with the initial correction parameters;

[0057] S4. Set a detection cycle, repeat steps S2 to S3 at fixed intervals in the detection cycle, obtain multiple current leveling plate pulse coefficients and current interval pulse coefficients, then average the current leveling plate pulse coefficients and current interval pulse coefficients based on the number of repetitions to obtain the leveling plate pulse coefficient and interval pulse coefficient of the elevator to be tested within the detection cycle;

[0058] Specifically, the current leveling board pulse coefficient and the current interval pulse coefficient are specifically expressed as follows:

[0059] C1=N HN3 / N HD3

[0060] C2=N DN1 / N D1

[0061] Among them, C1 is the current interval pulse coefficient, C2 is the current leveling board pulse coefficient, N HN3 is the current interval pulse, N HD3 is the initial interval pulse, N DN1 is the current leveling board pulse, N D1It is the initial leveling board pulse obtained during floor self-learning.

[0062] Specifically, in step S4, when taking the average of the current leveling plate pulse coefficient and the current interval pulse coefficient, the maximum and minimum values ​​are removed by using the truncated mean method, and then the remaining current leveling plate pulse coefficient and current interval pulse coefficient are averaged to obtain the leveling plate pulse coefficient and interval pulse coefficient of the elevator to be tested within the detection period. This setting is intended to prevent data deviation caused by failure of test components, thereby improving the accuracy of the automatic correction method for the elevator car leveling position.

[0063] S5. Use the leveling plate pulse coefficient and interval pulse coefficient obtained in step S4 to update the initial pulse parameters corresponding to the elevator to be checked, and complete the calibration of the elevator to be checked.

[0067] A floor self-learning module is used to perform floor self-learning operations on the elevator to be checked based on the initial operating parameters to obtain initial pulse parameters corresponding to the elevator to be checked; the initial pulse parameters include floor height pulse, initial leveling plate pulse and initial interval pulse;

[0068] A current pulse acquisition module is used to control the elevator to be checked to rise uniformly from the current floor at the verification speed, stop the elevator when the elevator to be checked passes the leveling plate position of the previous floor, and obtain the current leveling plate pulse and the current interval pulse;

[0069] A current pulse coefficient module is used to calculate the current leveling board pulse coefficient and the current interval pulse coefficient based on the current leveling board pulse and the current interval pulse in combination with the initial correction parameters;

[0070] A pulse coefficient acquisition module is used to obtain multiple current leveling plate pulse coefficients and current interval pulse coefficients at fixed intervals in the detection period, take the average, and obtain the leveling plate pulse coefficient and interval pulse coefficient of the elevator to be checked within the detection period;

[0071] The pulse parameter updating module is used to update the initial pulse parameters corresponding to the elevator to be checked with the obtained leveling plate pulse coefficient and interval pulse coefficient, so as to complete the calibration of the elevator to be checked.
