Description

Technical Field

[0001] This disclosure relates to the field of laundry equipment technology, and in particular to a weighing method, apparatus, electronic device and storage medium for a garment processing device. Background Technology

[0002] As people's living standards improve, consumers increasingly demand that washing machines can intelligently and automatically identify load information during operation, and then automatically set the most suitable washing parameters for the current clothes, such as washing temperature, spin speed, and rinsing speed. Among the load information, weight is highly correlated with the above washing parameters, and can directly affect the final washing effect. Therefore, accurately identifying the load weight is the foundation of intelligent washing machines.

[0003] Currently, the method for calculating the load weight of a large drum washing machine involves collecting motor operating parameters and inputting them into a fitted weight calculation formula set in the firmware to obtain the corresponding weight of the clothes. This calculation method is suitable for large drum scenarios where motor operating parameters and clothing weight are strongly correlated. However, for the small drum of a drum washing machine, it has a large resistance torque when empty, making the influence of changes in motor operating parameters on changes in clothing weight less significant. Therefore, in the case of a small drum washing machine, using motor operating parameters to calculate the weight of clothes results in a larger error. Summary of the Invention

[0105] Embodiments of this disclosure are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0106] As people's living standards improve, consumers increasingly demand that washing machines can intelligently and automatically identify load information during operation, and then automatically set the most suitable washing parameters for the current clothes, such as washing temperature, spin speed, and rinsing speed. Among the load information, weight is highly correlated with the above washing parameters, and can directly affect the final washing effect. Therefore, accurately identifying the load weight is the foundation of intelligent washing machines.

[0107] Currently, the method for calculating the load weight of a large drum washing machine involves collecting motor operating parameters and inputting them into a fitted weight calculation formula set in the firmware to obtain the corresponding weight of the clothes. This calculation method is suitable for large drum scenarios where motor operating parameters and clothing weight are strongly correlated. However, for the small drum of a drum washing machine, it has a large resistance torque when empty, making the influence of changes in motor operating parameters on changes in clothing weight less significant. Therefore, in the case of a small drum washing machine, using motor operating parameters to calculate the weight of clothes results in a larger error.

[0108] Therefore, in order to solve the problems existing in the related technologies, this disclosure proposes a weighing method for a garment processing device, which determines a target current relative value based on a first current and a second current, wherein the first current is the current when the drum accelerates, and the second current is the current when the drum rotates at a constant speed after acceleration. The garment load weight of the garment processing device is determined based on the target current relative value and the historical current relative value.

[0109] This scheme calculates the target current relative value based on the collected first and second currents of the motor, and compares the current relative value with the historical current relative value to determine the weight of the clothing load. This allows for the application of different historical current relative values ​​for weighing each clothing processing device, eliminating the error in calculating the weight of the clothing load while ensuring the accuracy of the historical current relative value.

[0121] Figure 1 This is a flowchart illustrating a weighing method for a garment processing device provided in this disclosure. This method can be applied to various scenarios involving garment processing devices (such as household washing machines, commercial washing machines, and multi-drum washing machines). For example, it can be executed by a garment processing device with integrated data processing capabilities or a processor within the garment processing device, or by other garment processing devices capable of calculating load weight and having a motor-driven load rotation function. Furthermore, it can also be executed by an IoT platform (such as a server) with bidirectional message communication capabilities within the garment processing device. This disclosure does not limit the scope of the method. Figure 1 As shown, the weighing method of the garment processing equipment includes steps 101-102.

[0122] Step 101: Determine the relative value of the target current based on the first current and the second current, wherein the first current is the current when the drum accelerates, and the second current is the current when the drum rotates at a constant speed after acceleration.

[0123] The garment processing equipment described in this embodiment includes a main control board, a frequency converter, a direct drive motor, and a data acquisition device. The main control board controls the washing process, the frequency converter controls the motor operation, the direct drive motor drives the washing drum (roller) to rotate, and the data acquisition device collects the motor's operating parameters.

[0124] When the main control board of the garment processing equipment is set to stand-alone washing mode, after the clothes to be washed are put into the garment processing equipment and the garment processing equipment is started, the frequency converter board controls the motor to run, and the washing drum is driven to rotate by the direct drive motor. It needs to go through two speed processes. The first speed process is called the climbing stage, and the second speed process is called the high-speed constant speed operation stage.

[0125] In practical applications, the garment processing equipment responds to the start command by having the controller send a start command to the motor and issue a first speed that the motor needs to reach. The direct drive motor accelerates to the first speed based on the start command, and this process is the climbing phase. After the controller detects that the motor has reached the first speed, it continues to send a command to the motor to continue to increase the speed to a second speed (the second speed is greater than the first speed). The direct drive motor responds to the start command to reach the second speed and runs at the second speed, which is the high-speed constant speed operation phase.

[0126] The data acquisition device collects the first current of multiple sets of direct-drive motors during the motor's climbing phase, and collects the second current of multiple sets of motors during the high-speed, constant-speed operation phase of the direct-drive motors. Specifically, this disclosure does not limit the specific type of data acquisition device or the number of first and second currents collected.

[0127] The purpose of calculating the relative value of the target current in this embodiment is to introduce the first current during the motor climbing phase and calculate the relative value of the first current during the motor climbing phase and the second current value during the high-speed uniform operation phase, thereby increasing the correlation of the calculated load weight, reducing the cumulative error, and thus improving the accuracy and stability of the calculation of the load weight of clothing.

[0128] Step 102: Determine the clothing load weight of the clothing processing equipment based on the target current relative value and the historical current relative value.

[0129] In related technologies, the calculation method for calculating the load weight of clothing has a certain consistency in different clothing processing equipment of the same model. However, for the scenario of small tube weighing, it has a large resistance torque when there is no clothing, which makes the changes in motor operating parameters not sensitive to the changes in clothing weight. At the same time, it results in a large variance between different clothing processing equipment, that is, poor consistency.

[0130] In this embodiment of the disclosure, when calculating the weight of the clothing load, the historical relative current value of each clothing processing device, i.e., the target relative current value, is used to calculate the complex weight of the clothing. Since the historical relative current value is the only historical data stored by the clothing processing device, it has the characteristics of being unique and singular. This enables the application of different or the same historical relative current value to weigh each clothing processing device, thereby eliminating the error caused by the inconsistency between different clothing processing devices while ensuring the accuracy of the historical relative current value.

[0131] In the embodiments of this disclosure, the calculated load weight of clothing can be a load weight range or a load weight value. Specifically, the embodiments of this disclosure do not limit the specific form of the load weight of clothing.

[0132] As one implementation of this disclosure, if a processor for determining the load weight of clothing is configured in a clothing processing device, after determining the load weight of clothing, the washing parameters or drying parameters corresponding to the load weight of clothing are obtained, and the clothing is washed or dried.

[0133] As another implementation of this disclosure, if the processor for determining the load weight of the clothes is configured in the server, after determining the load weight of the clothes, under network conditions, the server sends the load weight of the clothes and the corresponding washing parameters or drying parameters to the clothes processing device. After receiving the load weight of the clothes and the corresponding washing parameters or drying parameters, the clothes processing device performs washing or drying of the clothes.

[0134] In summary, the weighing method for the garment processing equipment proposed in this disclosure includes determining a target current relative value based on a first current and a second current, wherein the first current is the current during drum acceleration, and the second current is the current during uniform rotation of the drum after acceleration. The garment load weight of the garment processing equipment is determined based on the target current relative value and historical current relative values. The target current relative value is calculated based on the collected first and second motor currents, and then compared with historical current relative values ​​to determine the garment load weight. This method applies different historical current relative values ​​to weigh each garment processing device, eliminating errors in garment load weight calculation while ensuring the accuracy of the historical current relative values.

[0135] Figure 2A flowchart of a weighing method for a garment processing device proposed in this disclosure is further shown. Based on Figure 1 The illustrated embodiment further explains step 102. Figure 2 This may include the following steps:

[0136] Step 201: Determine the relative value of the target current based on the first current and the second current, wherein the first current is the current when the drum accelerates, and the second current is the current when the drum rotates at a constant speed after acceleration.

[0137] For details on step 201, please refer to the relevant detailed explanation of step 101, which will not be repeated here.

[0138] Step 202: Determine the weight of clothing load corresponding to the target relative current value based on the preset mapping relationship between the relative current value and the weight of clothing load.

[0139] Because the garment processing equipment has problems such as load eccentricity during operation, the motor parameters fluctuate greatly. Therefore, the embodiments of this disclosure pre-set the mapping relationship between the relative value of the single variable current and the load weight, which increases the stability between the relative value of the current and the load weight, reduces the cumulative error, and thus improves the accuracy of the load weight.

[0140] The process of presetting the mapping relationship between the relative value of the single variable current and the load weight is as follows: During the testing phase, the test data (including the calibrated relative current value and the calibrated load weight) are used to obtain the preset mapping relationship between the relative current value and the load weight of the clothing through linear fitting. This disclosure does not limit the fitting method used; any fitting method from related technologies can be employed.

[0141] Figure 3 A flowchart of a weighing method for a garment processing device proposed in this disclosure is further shown. Based on Figure 1 The illustrated embodiment further explains step 102. Figure 3 This may include the following steps:

[0142] Step 301: Sort the relative values ​​of the historical currents to obtain the sorting results.

[0143] Before calculating the load weight of the clothes in this (kth wash), the server or clothes processing equipment will store the historical (k-1) relative current values, sort all k-1 historical relative current values ​​according to their size, and obtain the sorting result.

[0144] like Figure 4 As shown, Figure 4This explanation uses an example of 12 washes (k=12). The circles in the diagram represent historical relative current values. When sorting, the values ​​are arranged from smallest to largest to obtain the sorting result. It should be clarified that this explanation is not intended to limit the number of washes or the sorting method. In practical applications, the historical relative current values ​​can also be sorted from largest to smallest; there are no specific restrictions.

[0145] Step 302: Determine the clothing load weight of the clothing processing equipment based on the target current relative value and the sorting result.

[0146] As one implementation of this disclosure, after obtaining the sorting results, there is a corresponding relationship between the historical relative current value and the historical clothing load weight. Therefore, when calculating the current clothing load weight, the target relative current value is first matched with the sorting results, and it is determined which historical relative current value in the sorting results the target relative current value matches, or which two historical relative current values ​​it is between. The clothing load weight is determined based on the matching results and the corresponding relationship between the historical relative current value and the historical clothing load weight.

[0147] As another implementation of this disclosure, this embodiment is applied to a scenario involving small-drum washing machines (such as underwear washing machines, sock washing machines, etc.). "Small-drum" refers to a washing drum with a capacity less than a preset capacity threshold, such as 1KG or 2KG. Since the weight of clothing that the washing machine can carry is relatively small, a range of clothing load weights can be determined first when determining the load weight of the washing machine. Figure 5 The method shown includes:

[0148] Step 501: Divide the load weight range into a preset number according to the sorting result, and the relative current magnitude corresponds to the load weight range.

[0149] Please continue reading. Figure 4 After sorting the historical relative current values, the system is further divided into a preset number of load weight intervals (taking three load weight intervals as an example). Load weight interval 1 is [1,3], load weight interval 2 is [4,7], and load weight interval 3 is [8,11]. In practical applications, the number of load weight intervals can be increased as the number of historical relative current values ​​increases, or the number of load weight intervals can be set and kept constant. Specific embodiments of this disclosure are not limited to this.

[0150] It should be noted that, taking a load weight range of 3 as an example, when the number of historical current relative values ​​is less than 3, i.e., when the number of washing cycles k=1 or k=2, it is not applicable to use [this method / approach]. Figure 5The method shown is used to determine the load weight because when the number of historical current relative values ​​is less than 3, it is impossible to divide the load weight range into a preset number.

[0151] Step 502: Match the relative value of the target current with a preset number of load weight ranges to determine the target load weight range.

[0152] The relative values ​​of the current correspond to the load weight ranges; that is, different load weight ranges are divided according to the magnitude of the relative current values, as can be seen from the figure. Figure 4 To illustrate, we will take three load weight ranges as an example. Each load weight range corresponds to a different weight level of clothing, as shown in the figure.

[0153] Since this embodiment applies to a small-drum scenario in a garment processing device, where the capacity of the washing drum is less than a preset capacity threshold (e.g., 1KG), and because the garment processing device can only handle a small amount of clothing, and the small drum itself is small in size and weight, it is not suitable for the precise weighing of conventional large drums. Therefore, a load weight range division method is adopted. Thus, this embodiment divides the garment load weight into three levels (light weight, medium weight, and heavy weight) to meet the requirements. For business needs with higher precision, the garment load weight can also be divided into four or five levels, etc.

[0154] Figure 4 This is merely an illustrative explanation of the relationship between relative current values, load weight ranges, and clothing load weights, and is not intended to limit the number of relative current values, the number and length of the divided load weight ranges, or the clothing load weight levels. Specific embodiments of this disclosure are not described.

[0155] As another implementation of the embodiments of this disclosure, besides Figure 4 In addition to the three-level garment load weight division shown, based on the preset mapping relationship between relative current values ​​and load weight ranges, after obtaining the target relative current value, the corresponding load weight range can be directly determined based on the preset mapping relationship between relative current values ​​and load weight ranges. The load weight range corresponds to the specific garment load weight. For example, load weight range 1: 1g-300g corresponds to a garment load weight of 150g, load weight range 2: 301g-700g corresponds to a garment load weight of 500g, load weight range 3: 701g-1000g corresponds to a garment load weight of 900g, and so on. Specifically, the correspondence between load weight ranges and garment load weights is not specifically limited in this embodiment.

[0156] The method described in this embodiment actively updates the historical relative current values ​​in the database after each wash, achieving an online learning function. That is, by continuously learning and adapting to data changes, long-term efficiency is improved. Specifically, after determining the load weight of the laundry processing equipment based on the target relative current value and historical relative current values, the target relative current value is stored as the historical relative current value for the next load weight calculation. Figure 4 The number of washes mentioned above, k=12 for this wash, will store the relative current value and the corresponding load weight of the clothes obtained in this calculation, so as to serve as the historical relative current value when calculating the load weight of the clothes in the next wash k=13.

[0157] In scenarios where load weighing is performed by a server, the server communicates with multiple garment processing devices. To ensure that a different model (trained from historical relative current values) is applied to each device for weighing, and to eliminate errors caused by inconsistencies between different machines while maintaining model accuracy, it is necessary to first determine which garment processing device's load weight is being calculated when calculating the garment load weight. Figure 6 As shown, it includes:

[0158] Step 601: Determine the relative value of the target current based on the first current and the second current, wherein the first current is the current when the drum accelerates and the second current is the current when the drum rotates at a constant speed after acceleration. Obtain the device identifier of the clothing processing equipment.

[0159] For details on step 601, please refer to the relevant detailed explanation of step 101, which will not be repeated here.

[0160] Step 602: Obtain the device identifier of the clothing processing equipment, and determine the corresponding historical current relative value based on the device identifier.

[0161] On the server side, historical relative current values ​​of all garment processing devices with which it has bidirectional data communication are stored. Therefore, before specifically calculating the garment load weight corresponding to the garment processing device, it is necessary to obtain the device identifier of the garment processing device and query the corresponding historical relative current value in the database based on the device identifier. This realizes that different historical relative current values ​​are used for weighing each garment processing device, eliminating the calculation error caused by the poor consistency between different machines.

[0162] When obtaining the device identifier, the device identifier of the clothing processing device can be carried when the clothing processing device reports the first current and the second current in step 601, or an instruction message to report the device identifier can be sent to the clothing processing device to obtain the device identifier. Specifically, the method of obtaining the device identifier is not limited in this embodiment.

[0163] Step 603: Determine the clothing load weight of the clothing processing equipment based on the target current relative value and the historical current relative value.

[0164] For details on step 603, please refer to the relevant detailed explanation of step 102, which will not be repeated here.

[0165] As illustrated in the above embodiments, this disclosure applies to scenarios where the garment handling equipment is a small drum. Therefore, before calculating the garment load weight, it should be determined whether the garment handling equipment is a small drum. If it is a large drum scenario, the method described in this disclosure is not applicable, because large drums require higher accuracy in calculating the garment load weight. The method described in this disclosure is insufficient to calculate a highly accurate garment load weight. Figure 7 As shown, it includes:

[0166] Step 701: Determine the capacity information of the washing drum based on the equipment identifier of the clothing processing equipment.

[0167] For instructions on obtaining the device identifier, please refer to the detailed explanation of step 602, which will not be repeated here.

[0168] When garment processing equipment leaves the factory, the capacity information corresponding to different equipment identifiers is determined. Therefore, once the equipment identifier is known, the capacity information of the corresponding washing drum can be determined.

[0169] Step 702: Determine the clothing load weight of the clothing processing equipment based on the capacity information, the target current relative value, and the historical current relative value.

[0170] When determining the clothing load weight of the clothing processing equipment based on the capacity information, the target current relative value, and the historical current relative value, the following methods can be used, but are not limited to: Figure 8 As shown, it includes:

[0171] Step 7021: Determine the corresponding rated capacity based on the capacity information.

[0172] In some embodiments, capacity information refers to the rated capacity of the garment processing equipment, specifically the rated capacity of the inner drum of the garment processing equipment.

[0173] In some embodiments, the capacity information may also include the cylinder volume; specifically, there are no limitations on the capacity information.

[0174] If the rated capacity is determined to be less than or equal to the preset capacity threshold, then step 7022 is executed; if the rated capacity is determined to be greater than the preset capacity threshold, then the process ends.

[0175] The preset capacity threshold needs to be set according to the specific size of the washing drum. For example, the preset capacity threshold may be 1kg, 2kg, etc., or, when the capacity information is the drum volume, the corresponding preset capacity threshold may be 6L, 10L, etc. The specific value is not limited.

[0176] Step 7022: Determine the clothing load weight of the clothing processing equipment based on the target current relative value and the historical current relative value.

[0177] For details on step 7022, please refer to the relevant detailed explanation of step 102, which will not be repeated here.

[0178] Figure 9 A flowchart of a weighing method for a garment processing device proposed in this disclosure is further shown. Based on Figure 1 The illustrated embodiment further explains step 101. Figure 9 This may include the following steps:

[0179] Step 901: Obtain the first current and the second current.

[0180] When obtaining the first current and the second current, the following methods can be used, but are not limited to: Figure 10 As shown, it includes:

[0181] Step 9011: Control the motor of the clothing processing device to accelerate from the first speed to the second speed, and collect the first current during the acceleration period according to the preset collection cycle.

[0182] The motor receives a first rotational speed r1 set by the processor. The motor drives the roller to accelerate from rest to the first rotational speed r1 with a first acceleration a1, and maintains this speed for a first time s1. After the processor detects that the roller has reached the first rotational speed r1 and the first time s1 has reached a preset threshold, it sends a second rotational speed r2 to the motor. The motor then drives the roller to accelerate from the first rotational speed r1 to the second rotational speed r2 with a second acceleration a2, and maintains this speed for a second time s2. The acquisition device collects the first current I during the acceleration period from the first rotational speed r1 to the second rotational speed r2 according to a preset acquisition cycle. S1 A total of n sets of data were collected, and the collected n sets of data are shown in formula (1):

[0183] I S1 ={i S1_1 i S1_2 i S1_3 ,…,i S1_m}Formula (1)

[0184] The magnitudes of the first acceleration a1 and the second acceleration a2 described in this embodiment are related to the motor power and are not specifically limited here.

[0185] In some embodiments, the preset sampling period is an empirical value. The smaller the sampling period, the larger the amount of data collected, and the more accurate the subsequent determination of the load weight, but the more computing resources are required. Conversely, the larger the sampling period, the smaller the amount of data collected, and the lower the accuracy of the subsequent determination of the load weight, but the less computing resources are required. Therefore, when setting the sampling period, it is also necessary to set it according to the processing resources of the garment processing equipment, such as setting it to 100ms, 80ms, or 120ms, etc. The specific settings are not limited in this embodiment.

[0186] Step 9012: Control the motor to run at the second speed at a constant speed, and collect the second current during operation according to the preset collection cycle.

[0187] After the motor reaches the second speed r2, it continues to run at the second speed r2. The data acquisition device collects the second current I when the drum runs at the second speed r2 (uniform speed operation) according to the preset acquisition cycle. S2 A total of m sets of data were collected, and the collected m sets of data are shown in formula (2):

[0188] I S2 ={i S2_1 i S2_2 i S2_3 ,…,i S2_n}Formula (2)

[0189] The preset sampling period mentioned in step 9012 is set in the same way as that in step 9011. Please refer to the detailed description of step 9011.

[0190] Step 902: Preprocess the first current and the second current respectively to obtain the maximum current value and the average current value.

[0191] When preprocessing the first current and the second current to obtain the maximum current and the average current respectively, the following methods can be used, but are not limited to: Figure 11 As shown, it includes:

[0192] Step 9021: Smooth the first current and the second current respectively to obtain the first pre-processed current and the second pre-processed current.

[0193] In this embodiment, the purpose of preprocessing the first current and the second current is to reduce the oscillation of the relative current value caused by the oscillation of the first current and the second current, which greatly increases the linearity between the relative current value and the load weight, thereby improving the accuracy and stability of the load weight calculation.

[0194] When preprocessing the first current and the second current to obtain the average value of the first current and the average value of the second current, the following methods can be used, but are not limited to:

[0195] For the first current I respectively S1 and the second current I S2 Smoothing is performed to obtain the first pre-processed current. and the second pretreatment current

[0196]

[0197]

[0198] Step 9022: Perform mean smoothing calculations on the first preprocessed current and the second preprocessed current respectively to obtain the maximum current value and the average current value.

[0199] Calculated The maximum value I S ′ 1 and mean I S ′ 2, as shown in equations (5) and (6).

[0200]

[0201] For the first pre-processing current The reason for calculating its maximum current is that the three-phase current fluctuates significantly during the speed ramp-up process of the small cylinder, and the average value cannot fully represent the motor's operating condition during the speed ramp-up phase; Regarding The reason for calculating its average current is that when the small cylinder operates at a fixed speed during the high-speed, constant-speed phase, the current fluctuation is small, and its average current can represent the motor's operating condition during the high-speed, constant-speed phase.

[0202] Step 903: Determine the relative value of the current based on the maximum current value and the average current value.

[0203] The relative value of the target current x is calculated as shown in formula (7). Using the relative value of the target current as an indicator can further reduce the error caused by current fluctuation.

[0204] x=|I S ′ 1-I S - 2|Formula (7)

[0205] It should be noted that the weighing method of the clothing processing equipment described in this embodiment is applicable to multiple weighing stages in a single washing process, such as weighing dry clothes and weighing wet clothes. The purpose of weighing dry clothes is to determine the corresponding washing parameters based on the dry clothes weighing results, and the purpose of weighing wet clothes is to determine the drying parameters based on the wet clothes weighing results.

[0206] like Figure 12 As shown, Figure 12 This application scenario uses a cloud server to calculate the load weight. After the user puts clothes into the small drum, closes the drum door, selects the small drum washing mode, and clicks the start button, the garment processing equipment receives the start command and proceeds accordingly. Figure 12 The process of controlling the washing is executed. For details on the washing control process, please refer to the detailed description of the above embodiments, and therefore will not be repeated here.
