Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," and the like in the specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments" unless expressly specified otherwise.
The operation control of the existing elevator mainly adopts an S-shaped curve control strategy. Referring to fig. 1, a schematic diagram of an S-shaped curve according to an embodiment of the present application is shown. As shown in fig. 1, the elevator operation phases include an acceleration operation phase, a constant speed operation phase, and a deceleration operation phase. The acceleration operation phase includes an acceleration start phase (T1 is a theoretical operation time of the acceleration start phase shown in fig. 1), a uniform acceleration phase (T2 is a theoretical operation time of the uniform acceleration phase shown in fig. 1), and an acceleration end phase (T3 is a theoretical operation time of the acceleration end phase shown in fig. 1). The deceleration operation phase includes a deceleration start phase (T5 is a theoretical operation time of the deceleration start phase shown in fig. 1), a uniform deceleration operation phase (T6 is a theoretical operation time of the uniform deceleration phase shown in fig. 1), and a deceleration end phase (T7 is a theoretical operation time of the deceleration end phase shown in fig. 1).
In the prior art, the position of the elevator is usually corrected during the deceleration run. When the elevator running distance is longer and the generated position deviation is larger, abrupt changes of speed and acceleration can be generated when the position correction is performed in the deceleration running stage, and the riding experience of a user is affected.
In order to solve the above problems, an embodiment of the present application provides an elevator operation control method. In an embodiment of the present application, the constant speed operation phase is divided into a first phase and a second phase, the first phase being between the second phase. As shown in fig. 1, the theoretical operating time of the constant-speed operating phase is T4, the second phase is the end phase of the constant-speed operating phase, and the theoretical operating time thereof is Tx.
In one application scenario, a starting time point of the second stage is preset. For example, when the elevator is moving to T3+x, the elevator enters the second stage, where T3.ltoreq.x<T4. When (when)The theoretical operation time of the second stage is longer than that of the first stage; when->The theoretical operating time of the second phase is less than the theoretical operating time of the first phase. When the elevator enters the second stage, the theoretical residual running time of the elevator running at a constant speed is Tx. In the second stage, tx is corrected according to the actual total displacement and the theoretical total displacement of the elevator operation, and the total time of the elevator constant-speed operation is corrected by correcting the residual operation time of the constant-speed operation, so that the position of the elevator is corrected.
Referring to fig. 2, a schematic flow chart of an elevator operation control method according to an embodiment of the present application is provided, by way of example and not limitation, and the method may include the following steps:
s201, when the elevator runs to the second stage, calculating the current actual total displacement of the elevator.
In an embodiment of the application, the point in time when the elevator is running to the second stage can be determined by means of a timer. In particular, since the operating parameters of the elevator after installation are determined, i.e. the theoretical operating times of the individual operating phases in the S-curve are known. As described in the application scenario in the embodiment of fig. 1, the starting time point of the second stage is preset, i.e. t3+x. And starting to count after the elevator is started, and when the counted time reaches T3+x, indicating that the elevator runs to the second stage.
Of course, the timing may also be started from the time when the elevator enters the constant speed operation phase. Specifically, when the running time after the elevator is started reaches T3, that is, the elevator enters a constant-speed running stage, a timer is started. When the timing time reaches x, it indicates that the elevator is running to the second stage. This corresponds to two times of timing.
In one embodiment, the actual total displacement is calculated by:
when the elevator runs to the second stage, the current encoder pulse number of the elevator is obtained; the current actual total displacement of the elevator is calculated according to the number of encoder pulses.
Generally, an encoder is mounted on a rotating shaft of a lifting device of an elevator. An encoder is a rotary sensor that converts rotary displacement into a series of digital pulse signals.
Optionally, one implementation of calculating the actual total displacement according to the number of encoder pulses is: counting the number of pulses sent by the encoder; determining the total rotation angle of the rotating shaft of the elevator lifting device according to the pulse number; and determining the linear displacement of the elevator lifting according to the corresponding circumference and the total rotation angle of each rotation of the rotating shaft.
Optionally, another implementation way of calculating the current actual total displacement of the elevator according to the number of encoder pulses is:
acquiring the rated speed of an elevator, the rated rotating speed of a motor and the pulse number of each rotation of an encoder; and calculating the current actual total displacement of the elevator according to the pulse number of the encoder, the rated speed, the rated rotating speed of the motor and the pulse number per revolution of the encoder.
Specifically, the actual total displacement is calculated according to the following formula:
S_qep＝K×C_pulse；
where S_ qep is the actual total displacement, K is the elevator parameter, C_pulse is the encoder pulse number,
s202, calculating the theoretical total displacement at the end of the constant speed operation phase of the elevator.
The theoretical total displacement refers to the theoretical total displacement calculated from the S-curve strategy and elevator parameters. However, in practical application, the actual total displacement of the elevator is deviated from the theoretical total displacement generally due to motor clamping, rope friction, overload and the like.
In one embodiment, the theoretical total displacement is calculated by:
respectively calculating a first theoretical displacement in an acceleration operation stage and a second theoretical displacement in a constant-speed operation stage of the elevator; and calculating theoretical total displacement according to the first theoretical displacement and the second theoretical displacement.
As shown in fig. 1, the acceleration operation phase includes an acceleration start phase, a uniform acceleration phase, and an acceleration end phase.
Optionally, the calculation method of the first theoretical displacement includes:
1. the method comprises the steps of acquiring an operation parameter of an acceleration start stage, an operation parameter of a uniform acceleration stage and an operation parameter of an acceleration end stage.
In the embodiment of the application, the operation parameters of the acceleration start stage include turning speed V1 (i.e. turning speed from the acceleration start stage to the uniform acceleration stage) and rapid acceleration J1; the operation parameters of the uniform acceleration stage include turning speed V2 (i.e. turning speed from the uniform acceleration stage to the acceleration ending stage) and maximum acceleration ACC; the operation parameters of the acceleration ending stage include turning speed V3 (i.e. turning speed from the acceleration ending node to the constant speed operation stage) and rapid acceleration J3; the operating parameters of the constant speed operating phase include a constant speed operating time T4. The turning speed V3 is also the operation speed in the constant-speed operation stage.
2. And calculating a third theoretical displacement of the acceleration start phase according to the operation parameters of the acceleration start phase.
According to the formulaA third theoretical displacement S1 of the acceleration start phase is calculated.
3. And calculating a fourth theoretical displacement of the uniform acceleration stage according to the operation parameters of the uniform acceleration stage.
According to the formulaA fourth theoretical displacement S2 of the ramp-up phase is calculated.
4. And calculating a fifth theoretical displacement of the acceleration ending stage according to the operation parameters of the acceleration ending stage.
According to the formulaA fifth theoretical displacement S3 of the acceleration end phase is calculated.
5. The sum of the third theoretical displacement, the fourth theoretical displacement and the fifth theoretical displacement is determined as the first theoretical displacement of the acceleration operation phase of the elevator.
According to the above formula, the first theoretical displacement=s1+s2+s3.
Optionally, the calculating means of the second theoretical displacement includes:
acquiring a first theoretical speed and theoretical running time of a constant-speed running stage; the product of the first theoretical speed and the theoretical operating time is determined as a second theoretical displacement of the constant speed operating phase.
The second theoretical displacement S4 is calculated according to the formula s4=v3×t4.
As described above, theoretical total displacement=s1+s2+s3+s4.
S203, correcting the residual operation time of the elevator in constant-speed operation according to the actual total displacement and the theoretical total displacement.
In one embodiment, the remaining runtime is determined by:
acquiring a first theoretical speed of the elevator in a constant-speed operation stage; calculating a displacement difference between the actual total displacement and the theoretical total displacement; and calculating the residual operation time according to the displacement difference value and the first theoretical speed.
Specifically, according to the formulaThe corrected remaining run time Tx' is calculated. Where S_cal is the theoretical total displacement.
S204, controlling the elevator to run according to the residual running time of the elevator in constant-speed running.
After correcting the remaining operation time of the constant-speed operation, the controller controls the elevator to operate at constant speed at the speed of V3 for Tx' time.
When the elevator enters the second stage, if the actual total displacement of the elevator is smaller than the theoretical total displacement, the calculated corrected residual operation time is larger than the original theoretical residual time Tx, namely the time of the elevator in constant-speed operation is increased, so that the displacement of the elevator in constant-speed operation is increased, and the correction of the elevator position in the constant-speed operation stage is completed.
In practical application, in order to avoid the situation that when the elevator enters the second stage, the actual total displacement of the elevator is greater than the theoretical total displacement, the starting time point of the second stage may be advanced, i.e. x takes a smaller value as described in the application scenario of the embodiment of fig. 1. In a critical situation, the second phase is entered when the elevator enters the constant speed operation phase, i.e. the time after the start of the elevator is equal to T3. Of course, the setting of x can be set according to actual needs.
In another application scenario, the starting position point of the second stage may also be preset. For example, when the elevator is running to s_t3+y. Wherein S_T3 is the theoretical displacement corresponding to the time when the running time of the elevator reaches T3, and y is the displacement increment. Under the application scene, the residual operation time of the constant-speed operation stage can be corrected according to the actual total displacement and the theoretical total displacement when the elevator enters the second stage, and the residual operation displacement of the constant-speed operation stage can also be corrected according to the actual total displacement and the theoretical total displacement when the elevator enters the second stage. The computing ideas involved in this scenario are similar to those described in the embodiment of fig. 2 above and are not described in detail herein.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic, and should not limit the implementation process of the embodiment of the present application.
