Technical Field

Background
Currently, there are two general methods for controlling the starting torque of an elevator: compensation current activation with and without weighing means. The elevator with the weighing device can compensate the starting moment of the elevator by the weighing value obtained by the weighing device before the elevator starts, which can enable the elevator to achieve higher starting comfort. In order to save the cost, some elevators cancel weighing devices, and some realize quick adjustment of starting moment by adjusting PI parameters, for example, the published patent documents CN201911022047.7 and CN201610134676.9; some elevator brake is opened instantly, and the average acceleration value of the elevator car participates in the calculation of the starting moment to compensate, for example, the publication CN202110984478.2; there are also methods using a pre-applied torque to compensate for the appropriate amount, for example, as disclosed in patent publication CN202111655143.2. The above methods are all compensation measures taken before the change of the car load is not acquired.
In the elevator system without the weighing device, the starting moment compensation method disclosed in the prior art cannot know the load change of the elevator car before the elevator is started, if the elevator car is only dependent on the moving direction and displacement of the elevator car as feedback of the starting moment, the influence on the comfort level of the elevator is large, and the response speed of the feedback loop is low, especially when the load change of the elevator is large, the comfort level of passengers is greatly reduced.

Detailed Description
Other advantages and technical effects of the present invention will become more fully apparent to those skilled in the art from the following disclosure, which is a detailed description of the present invention given by way of specific examples. The invention may be practiced or carried out in different embodiments, and details in this description may be applied from different points of view, without departing from the general inventive concept. It should be noted that the following embodiments and features in the embodiments may be combined with each other without conflict. The following exemplary embodiments of the present invention may be embodied in many different forms and should not be construed as limited to the specific embodiments set forth herein. It should be appreciated that these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the technical solution of these exemplary embodiments to those skilled in the art.
Example 1
In the elevator system according to the present embodiment, as shown in fig. 1, an acceleration sensor is installed on the car side of the elevator, and data communication (wired or wireless communication) can be performed between the acceleration sensor and the elevator control cabinet, and the control cabinet controls the hoisting machine. The acceleration sensor may be mounted on the top of the elevator car or on the bottom of the elevator car.
As shown in fig. 2, the present embodiment provides a method for calculating starting moment of an elevator, including the following steps:
step S1, estimating the load in the elevator car before the elevator car stops according to the moment current of the elevator traction machine during the running of the elevator car;
step S2, acquiring elevator car vertical acceleration data during the process that the elevator is stopped at a landing, extracting characteristic values of the vertical acceleration data, and judging the number of passengers entering and exiting the elevator car;
step S3, estimating the load change value of the elevator car according to the number of passengers entering or exiting the elevator car or the vertical acceleration data;
step S4, determining the load in the elevator car before starting according to the load in the elevator car before stopping and the load change value of the elevator car;
and S5, calculating the starting moment of the elevator according to the load in the elevator car before starting the elevator car.
Wherein the load in the car before stopping the elevator car in step S1 is estimated by the elevator control cabinet based on the measured moment current of the elevator hoisting machine.
The step S2 is calculated by the control cabinet side or the sensor side, and the specific method is to obtain vertical acceleration data of the elevator during the period that the elevator is stopped at a landing, specifically, the vertical acceleration data of the elevator car can be obtained by taking the opening time of the elevator car as a starting point and taking the closing time as an ending point when the elevator car is in place during the landing, and extracting characteristic values of the vertical acceleration data (the detection values of the acceleration sensor are obvious characteristics when passengers enter and exit the elevator car), and the method can obtain:
number of passengers entering and exiting the elevator car = count of passengers entering the car-count of passengers exiting the car.
Illustratively, the count of passengers entering the car and the count of passengers leaving the car may be obtained as follows.
Step S21: acquiring elevator car vertical acceleration data during elevator stopping at landing
Step S22: smoothing the vertical acceleration data to obtain a smoothed acceleration signal a smooth The method comprises the steps of carrying out a first treatment on the surface of the As shown in fig. 3.
Step S23: setting a threshold value Thr for the smooth acceleration signal according to different floors, identifying whether a peak value larger than the threshold value Thr exists in the characteristic signal, and judging that passengers enter or exit the car if the peak value larger than the threshold value Thr exists in the characteristic signal;
step S24: taking a smooth The peak comparison base value is determined as follows:
if the difference value between the previous peak value and the highest peak value of the highest peak value is within 10%, determining the previous peak value as a peak value comparison base value Pr, otherwise, taking the highest peak value as the peak value comparison base value Pr;
step S25: if the difference value of the peak value comparison basic value Pr and the previous peak value is smaller than Pr multiplied by 1/3, the elevator is judged to leave the elevator, if the difference value of the peak value comparison basic value Pr and the previous peak value is larger than Pr multiplied by 0.4, the elevator is judged to enter the elevator, and the number of passengers leaving the elevator is counted to obtain the count value of the passengers leaving the elevator; the number of passengers entering the elevator car is counted, and a count value of the passengers entering the elevator car is obtained.
Because the length of the steel wire rope of the elevator is shorter at a position close to the elevator traction machine, such as a higher floor, the measured value of the acceleration sensor is relatively smaller when passengers enter and exit the elevator car; the length of the wire rope at a position far from the elevator traction machine is long, such as a lower floor, and the measured value of the acceleration sensor is relatively large when passengers get in or out of the car. So that the threshold for the trigger signature needs to be adjusted appropriately. That is, the threshold value Thr set on different floors is different, and the threshold value Thr is set larger for the floor which is farther from the elevator traction machine.
Wherein step S3 is calculated by the control cabinet side or the sensor side, and one of the specific methods is to estimate the load change value of the elevator car according to the following formula:
elevator car load change value = passenger standard weight x number of passengers coming in and going out of the elevator car.
The standard weight of the passenger can be obtained by national standards, for example calculated as 75 kg per person.
The second method is to estimate the load change value of the elevator car according to the following formula,
wherein the method comprises the steps of
KL: correction coefficient of elevator car load at different floors
The higher the floor on which the elevator car is located, the greater the KL value. And secondly, the weight difference of different passengers can be corrected through the maximum acceleration peak value, and meanwhile, the influence of the elevator car position on the maximum acceleration value is corrected, so that the calculation of the elevator car load change value with higher precision is realized.
The step S4 is completed by a control device at the side of the control cabinet, and the specific method comprises the following steps:
load in car before elevator car start = load in car before elevator car stop + elevator car load change value;
the step S5 is completed by the control device at the side of the control cabinet, and the load in the elevator car before the elevator car is started is obtained, so that the function of the weighing device is realized, the output of the starting moment is optimized, and passengers can obtain comfortable riding experience.
Example 2
The elevator starting moment calculation method provided by the embodiment on the basis of embodiment 1 further comprises the following steps:
step S6, presetting a starting moment correction coefficient a for each floor i When the elevator is started, the starting moment of the elevator is corrected according to the starting moment correction coefficient corresponding to the starting floor of the elevator.
The initial value of the starting moment correction coefficient is set to 1, and then the starting moment correction coefficient of each floor is corrected according to the direction and the magnitude of the actual vertical acceleration of the elevator car each time the elevator starts at that floor (the car goes up or down). The starting moment correction coefficients of all floors after correction can be different, the starting moment correction coefficient of the same floor can be further divided into an uplink starting moment correction coefficient and a downlink starting moment correction coefficient, and the uplink starting moment correction coefficient and the downlink starting moment correction coefficient of the same floor can also be different. Thus, accurate compensation is realized.
The correction method of the starting moment correction coefficient is specifically that when the direction and the magnitude of the vertical acceleration of the elevator car meet the preset acceleration curve of the starting operation of the elevator car during the starting of the elevator, the compensation value is considered to be suitable. If the acceleration direction is not consistent with the target running direction, when the elevator car is started, the moment in the target direction needs to be increased; when the acceleration direction is consistent with the target running direction and exceeds the preset acceleration when the elevator car is started, the moment in the target direction needs to be reduced. The increased or decreased moment value can be converted into a correction factor as the next starting moment correction factor for the elevator when the car starts up in the floor under similar load, which correction method can form a self-learning process of the starting moment correction factor. In order to realize more accurate compensation, the starting moment correction coefficients are different for different car load intervals of a certain floor, so that the starting moment correction coefficient of the certain floor is actually a curve related to the car load interval.
According to the method, the estimated starting moment can be estimated through the detection value of the actual starting acceleration of the elevator car, so that the starting moment value started on the floor next time is corrected, an automatic correction and automatic learning process is formed, and the starting comfort of the elevator car can be obviously improved.
