The words "if" / "if" used herein can be interpreted as "at the time of" or "when" or "in response to determination".

The character " / " generally indicates that the associated objects are in an "or" relationship.

[0028] See also Figure 1 , which is a flow chart of a motor travel acquisition method of an embodiment of the present application. The motor travel acquisition method of this embodiment is applied to a clothes drying device, wherein the clothes drying device includes a motor and a clothes drying rod. When the motor is running, the clothes drying rod is driven to rise or fall. The motor travel acquisition method includes:

[0029] S1: Obtaining the motor load parameter, motor running speed and running time of the motor.

[0030] Among them, the motor load parameters, motor operating speed and operating time all refer to the motor operation data before the motor stops.

[0031] The motor load parameter refers to the resistance overcome when the motor runs to drive the load object to move. For example, when the motor runs to drive the clothesline to move, the resistance overcome includes: the weight of the clothesline and the weight of the items hung on the clothesline. The motor running speed refers to the rotational speed of the motor when it drives the load object to move. The running time refers to the time from the start of the motor to the stop of the motor.

[0032] S2: Acquire stroke compensation data of the motor according to the motor running speed, the running time, the motor load parameter and a preset load coefficient.

[0033] The stroke compensation data refers to the data that is not saved because the motor is stopped.

[0034] See also Figure 2 In a feasible embodiment, the stroke compensation data of the motor can be obtained by the following steps:

[0035] S21: Obtaining a first running stroke before the motor stops according to the running speed of the motor and the running time.

[0036] The first running stroke before the motor stops is not affected by the motor stopping, so the first running stroke is proportional to the running speed and running time of the motor.

[0037] S22: Obtaining a second running stroke after the motor stops according to the motor load parameter and the load coefficient.

[0038] After the motor stops, under the influence of the motor load parameters, the motor speed will gradually decrease to zero. Therefore, the second operating stroke after the motor stops is affected by the motor load parameters. Specifically, the relationship between the second operating stroke and the motor load parameters is expressed by a preset load coefficient, where the load coefficient has a value range of (0, 1.4).

[0039] S23: Obtaining the stroke compensation data according to the first operation stroke and the second operation stroke.

[0040] The stroke compensation data can be obtained by superimposing the first operation stroke and the second operation stroke.

[0041] S3: acquiring target stroke data of the motor according to the historical stroke data of the motor, the running direction of the motor and the stroke compensation data.

[0042] The historical travel data refers to the travel data before the motor runs this time, and can be the travel data after the motor stops running last time. The running direction of the motor determines the addition and subtraction relationship between the historical travel data and the travel compensation data. After adding and subtracting the historical travel data and the travel compensation data according to the running direction, the target travel data of the motor can be accurately obtained.

[0043] Compared with the related art, the present application obtains the stroke compensation data of the motor based on the motor load parameters, motor running speed and running time before the motor stops, and a preset load coefficient, and then obtains the target stroke data of the motor based on the motor's historical stroke data, the motor's running direction and stroke compensation data. It combines the parameters before the motor stops and the influence of the motor load parameters on the motor's electronic stroke after the motor stops, so that when the motor stops, accurate target stroke data of the motor can be obtained. In particular, when the motor stops suddenly, the present application can also obtain accurate target stroke data of the motor, overcoming the technical problem in the prior art that the accurate acquisition of the electronic stroke is affected by sudden conditions such as emergency stops of the motor.

[0044] In a feasible embodiment, the step S21: obtaining a first running stroke of the motor before the motor stops according to the running speed of the motor and the running time, comprises:

[0045] The first running stroke is obtained by the following formula:

[0046] S1=V×T

[0047] Wherein, S1 is the first running stroke, V is the motor running speed, and T is the running time.

[0048] In this embodiment, data of the first running stroke can be accurately obtained according to the running speed and running time of the motor.

[0049] In a feasible embodiment, the step S22: obtaining a second running stroke after the motor stops according to the motor load parameter and the load coefficient, comprises:

[0050] The second running stroke is obtained by the following formula:

[0051] S2=F×f

[0052] Among them, S2 is the second operating stroke, F is the motor load parameter, and f is the load coefficient.

[0053] In this embodiment, data of the first operating stroke can be accurately obtained according to the motor load parameter and the load coefficient.

[0054] In a feasible embodiment, the step S23: obtaining the stroke compensation data according to the first operating stroke and the second operating stroke includes:

[0055] The stroke compensation data is obtained by the following formula:

[0056] S=S1+S2

[0057] Wherein, S is the stroke compensation data, S1 is the first operating stroke, and S2 is the second operating stroke.

[0058] In this embodiment, stroke compensation data can be accurately obtained according to the first operating stroke and the second operating stroke.

[0059] See also Figure 3 In a feasible embodiment, the step of S3: acquiring the target stroke data of the motor according to the historical stroke data of the motor, the running direction of the motor and the stroke compensation data, comprises:

[0060] S31: If the running direction of the motor is the first direction, the sum of the historical stroke data and the stroke compensation data is determined as the target stroke data.

[0061] Among them, for the clothes drying equipment, the first direction is the direction in which the motor drives the clothes drying rod to descend.

[0062] S32: If the running direction of the motor is the second direction, the difference between the historical stroke data and the stroke compensation data is determined as the target stroke data.

[0063] Among them, for the clothes drying equipment, the second direction is the direction in which the motor drives the clothes drying rod to rise.

[0064] In a feasible embodiment, the step of S1: obtaining the motor load parameter before the motor stops, comprises:

[0065] S11: Acquire current parameters output to the motor when the motor is running.

[0066] The current parameter output to the motor refers to the current used to drive the motor to run, that is, the current output to the motor.

[0067] S12: According to the preset correspondence between the current parameter and the load parameter, the motor load parameter corresponding to the current parameter is obtained.

[0068] Among them, the greater the resistance overcome by the motor when driving the load object to move, the greater the current required for the motor to operate, that is, the greater the current parameter output to the motor, therefore, the corresponding relationship between the preset current parameter and the load parameter is positively correlated, that is, the corresponding relationship between the current parameter and the load parameter is expressed as the greater the current parameter, the greater the motor load parameter.

[0069] In this embodiment, according to the correspondence between the preset current parameters and the load parameters, the motor load parameters corresponding to the motor operation can be obtained.
