Description

Technical Field

[0001] The present application relates to the field of material identification, and more specifically, to a clothing material identification method, clothing processing equipment and a control method thereof. Background Art

[0002] Take clothing processing equipment as an example. It is an indispensable device in daily life. It can perform such processing as washing, dehydrating, drying, and caring for clothing, which greatly improves the convenience of clothing processing. With the development of technology and the increase in user needs, the processing accuracy of clothing by clothing processing equipment has also improved. Taking washing machines as an example, current washing machines usually identify the material of clothing before processing it, so that different materials of clothing can use different processing parameters, which helps to improve the processing effect of clothing.

[0003] At present, material recognition mostly relies on cameras and other photographic devices, which use image algorithms to identify the material of clothing through the captured clothing images. However, in actual use, clothing not only easily blocks the camera, but also easily forms water mist or fails to automatically focus, resulting in poor clarity of the captured clothing images, which reduces the accuracy of clothing material recognition. Summary of the invention

[0004] The embodiments of the present application provide a clothing material identification method, a clothing processing device and a control method thereof, so as to at least solve the technical problem of reduced accuracy in identifying clothing materials.

[0005] According to a first aspect of an embodiment of the present application, a method for identifying clothing material is provided, the method comprising:

[0006] Acquire a plurality of diffuse reflection parameter values ​​when the clothing diffusely reflects an incident light signal;

[0007] The clothing material of the clothing is determined according to the correspondence between the plurality of diffuse reflection parameter values ​​and the preset clothing material and diffuse reflection standard value interval.

[0008] In this embodiment, since the light signal is used to detect the material of the clothing, the detection accuracy is not easily affected by water mist, and there is no need for autofocus, which helps to improve the recognition accuracy of the clothing material. In addition, the diffuse reflection of the incident light signal is used to detect the clothing, and there is no need to penetrate the clothing for detection, so it is not easy to have the defect of being unable to detect due to the inability of the incident light signal to penetrate the clothing, which further ensures the smooth recognition of the clothing material and helps to improve the recognition accuracy of the clothing material.

[0009] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the step of obtaining a plurality of diffuse reflection parameter values ​​when the clothing diffusely reflects the incident light signal includes:

[0010] Controlling the emitter of the light detection element to transmit the incident light signal to the clothes covering the light detection element for multiple times;

[0011] The light detection element receives, by a receiving pole of the light detection element, reflected light signals which are diffusely reflected by the clothing to the incident light signal for multiple times;

[0012] Data conversion processing is performed based on the wavelength and / or light intensity of the reflected light signal received a plurality of times in the light detection element to obtain the plurality of diffuse reflection parameter values.

[0013] With this implementation, when identifying the clothing material of clothing, the incident light signal will be emitted multiple times, so that the reflected light signal is received a very large number of times. Then it is converted to obtain multiple diffuse reflection parameter values. On the one hand, compared with one diffuse reflection parameter value, multiple diffuse reflection parameter values ​​are conducive to avoiding special situations and improving the accuracy of clothing materials identified based on diffuse reflection parameter values. On the other hand, the wavelength, light intensity and other information of the reflected light signal are not directly used, but data conversion processing is performed, so that the diffuse reflection standard value intervals corresponding to different clothing materials have large differences, which is conducive to improving the accuracy of clothing material identification and avoiding the phenomenon of non-recognition due to the small difference in the diffuse reflection standard value intervals corresponding to different clothing materials.

[0014] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the light detection element is an ultraviolet sensor or an infrared sensor, and the emitter and the receiver of the light detection element are arranged in parallel and flatly under the clothing.

[0015] With this implementation, the ultraviolet sensor or infrared sensor is low-cost and is not likely to cause damage to clothing and the human body. The parallel and flatly arranged emitter and receiver are conducive to reducing the space occupied by the light detection element and improving the installation convenience of the light detection element.

[0016] In combination with the first aspect, in an optional implementation of the embodiment of the present application, determining the clothing material of the clothing according to the correspondence between the multiple diffuse reflection parameter values ​​and the preset clothing material and diffuse reflection standard value interval includes:

[0017] Determining a representative value according to the plurality of diffuse reflection parameter values;

[0018] Compare the representative value with each of the diffuse reflectance standard value intervals to determine the diffuse reflectance standard value interval to which the representative value belongs;

[0019] According to the corresponding relationship, the clothing material corresponding to the diffuse reflection standard value interval to which the representative value belongs is determined as the clothing material of the clothing.

[0020] By adopting this implementation, the material of the clothing is determined based on the diffuse reflection standard value interval to which the representative value determined according to multiple diffuse reflection parameter values ​​belongs, which helps to improve accuracy.

[0021] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the representative value includes at least one of a maximum value, a minimum value, an intermediate value and an average value.

[0022] With this implementation, no matter the maximum value, minimum value, middle value or average value, they are all representative in certain circumstances, so that the representative value can better reflect the characteristics or features of multiple diffuse reflection parameter values, thereby making the clothing material of the clothing determined according to the representative value more accurate.

[0023] In combination with the first aspect, in an optional implementation manner of the embodiment of the present application, the method further includes:

[0024] After acquiring the plurality of diffuse reflection parameter values, determining the validity of the plurality of diffuse reflection parameter values ​​according to the stability of the plurality of diffuse reflection parameter values, wherein the validity includes valid and invalid;

[0025] If the plurality of diffuse reflection parameter values ​​are valid, determining the clothing material of the clothing according to the plurality of diffuse reflection parameter values ​​and the correspondence between the preset clothing material and the diffuse reflection standard value interval;

[0026] If the multiple diffuse reflection parameter values ​​are invalid, the spatial distribution state of the clothing is changed according to the clothing adjustment strategy and the multiple diffuse reflection parameter values ​​are reacquired when the clothing diffusely reflects the incident light signal.

[0027] With this implementation, the validity of multiple diffuse reflection parameter values ​​will be judged. Only when multiple diffuse reflection parameter values ​​are valid, the clothing material of the clothing will be determined based on the multiple diffuse reflection parameter values ​​and the corresponding relationship, thereby ensuring the accuracy of the determined clothing material. For invalid multiple diffuse reflection parameter values, multiple diffuse reflection parameter values ​​will be re-acquired. Since re-acquisition also belongs to the case of acquiring multiple diffuse reflection parameter values, the validity will be determined again, and so on, to achieve cyclic processing, which helps to improve the accuracy of the determined clothing material.

[0028] In combination with the first aspect, in an optional implementation of the embodiment of the present application, determining the validity of the multiple diffuse reflection parameter values ​​according to the stability of the multiple diffuse reflection parameter values ​​includes:

[0029] The validity of the multiple diffuse reflection parameter values ​​is determined according to the discreteness of the multiple diffuse reflection parameter values, wherein the discreteness is used to characterize the stability of the multiple diffuse reflection parameter values.

[0030] By adopting this implementation, when determining the validity of multiple diffuse reflection parameter values, the validity is determined according to the discreteness of the multiple diffuse reflection parameter values, and the calculation process is simple, which helps to reduce the occupation of computing resources.

[0031] In combination with the first aspect, in an optional implementation manner of the embodiment of the present application, determining the validity of the multiple diffuse reflection parameter values ​​according to the discreteness of the multiple diffuse reflection parameter values ​​includes:

[0032] Calculating an average value of the plurality of diffuse reflection parameter values;

[0033] Calculating a standard deviation representing the degree of dispersion using the average value and the plurality of diffuse reflection parameter values;

[0034] If the standard deviation exceeds a preset validity threshold, determining that the plurality of diffuse reflection parameter values ​​are invalid;

[0035] If the standard deviation does not exceed the validity threshold, it is determined that the multiple diffuse reflection parameter values ​​are valid.

[0036] By adopting this implementation method, the discreteness of multiple diffuse reflection parameter values ​​is measured by standard deviation, the calculation process is simple, and it helps to reduce the occupation of computing resources.

[0037] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the clothes are located in a clothes processing drum, and the changing of the spatial distribution state of the clothes according to the clothes adjustment strategy includes:

[0038] The laundry processing drum is controlled to rotate at a preset angle.

[0039] By adopting this embodiment, the control process is simple and quick, which is conducive to improving the efficiency of clothing material recognition.

[0040] In combination with the first aspect, in an optional implementation of the embodiment of the present application, after controlling the laundry processing drum to rotate by a preset angle, the method further includes:

[0041] The rotation of the laundry processing drum is controlled according to the preset dithering parameters, so as to re-acquire a plurality of diffuse reflection parameter values ​​when the laundry diffusely reflects the incident light signal after the laundry processing drum stops rotating.

[0042] By adopting this embodiment, after running the shaking parameters, it is beneficial to change the state and arrangement order of the clothes in the clothing processing drum, so that the re-acquired multiple diffuse reflection parameter values ​​are not likely to be the same as or have a high degree of similarity with the previously acquired ones, which helps to increase the difference between the previously acquired and re-acquired multiple diffuse reflection parameter values, so that the re-acquired multiple diffuse reflection parameter values ​​are easy to be determined as valid, thereby reducing the number of times multiple diffuse reflection parameter values ​​are acquired and improving the clothing material recognition efficiency of the clothes.

[0043] According to a second aspect of an embodiment of the present application, a method for controlling a laundry processing device is provided, the method comprising:

[0044] The clothing material identification method described above is used to identify the clothing material of the clothing in the clothing treatment drum;

[0045] The clothing processing device is controlled to execute corresponding operating parameters according to the clothing material of the clothing.

[0046] In this embodiment, when the clothing processing device is used, the above-mentioned clothing material identification method will be used to identify the clothing material of the clothing in the clothing processing device. After obtaining the clothing material of the clothing, the corresponding operating parameters will be executed according to the clothing material of the clothing, so that when the clothing processing device processes the clothing, different operating parameters will be executed for different types of clothing materials, which is conducive to improving the processing effect of the clothing.

[0047] In conjunction with the second aspect, in an optional implementation manner of the embodiment of the present application, the method further includes:

[0048] When the number of times of identifying the material of the clothes in the clothes processing drum reaches a preset number threshold, the identification is stopped.

[0049] By adopting this implementation method and setting a number threshold, the number of times the clothing material is identified can be limited, so that the clothing processing device will not be in the clothing material identification stage for a long time, which is beneficial to improving the clothing processing efficiency of the clothing processing device.

[0050] According to a third aspect of an embodiment of the present application, an electronic device is provided, the electronic device comprising a memory and a processor;

[0051] The memory is used to store computer programs;

[0052] The processor is used to execute the computer program to implement the steps of the method described above.

[0053] According to a fourth aspect of an embodiment of the present application, there is provided a laundry processing device, comprising a laundry processing drum that can be controlled to rotate, wherein a light detection element is disposed on the laundry processing drum;

[0054] The clothing processing device uses the above-mentioned clothing material identification method to identify the clothing material.

[0055] In combination with the fourth aspect, in an optional implementation of the embodiment of the present application, at least one lifting rib is provided on the clothing processing drum, at least one of the lifting ribs has a receiving groove formed therein, and the light detection component is located in the receiving groove.

[0056] With this implementation, a receiving groove is provided on the lifting rib for installing the light detection element, so that the light detection element is not easily entangled with the clothes in the laundry treatment drum, and thus the light detection element is not easily affected by the movement of the clothes in the laundry treatment drum. At the same time, the light detection element is located in the lifting rib, and the distance between the light detection element and the clothes can change with the position of the lifting rib, which is conducive to improving the detection of the clothes by the light detection element and improving the detection quality.

[0057] In combination with the fourth aspect, in an optional implementation of the embodiment of the present application, the light detection element includes an emitter and a receiver, and the emitter and the receiver are arranged in the receiving groove in a parallel and flat manner, the emitter is used to emit an incident light signal into the clothing processing drum, and the receiver is used to receive a reflected light signal after contact with the clothing in the processing drum and diffuse reflection.

[0058] In combination with the fourth aspect, in an optional implementation of the embodiment of the present application, the transmitter and the receiver are arranged in sequence along the rotation direction of the laundry processing drum and are parallel to each other;

[0059] There is a distance between the end surfaces of the emitting electrode and the receiving electrode and the upper end surface of the lifting rib.

[0060] By adopting this implementation, the light detection element is installed in a manner of setting a certain distance, so that when the clothes cover the upper end surface of the lifting rib, there is still a certain distance between the clothes and the light detection element, which helps to improve the detection quality of the light detection element.

[0061] In combination with the fourth aspect, in an optional implementation of the embodiment of the present application, a cover plate for covering the receiving groove is provided on the lifting rib, and the cover plate is a waterproof and light-transmitting plate.

[0062] By adopting this implementation method, a cover plate is provided to facilitate sealing the receiving groove, so that the water in the clothing processing drum not only enters the receiving groove, but also protects the optical detection element from being easily infiltrated or soaked by water, thereby increasing the service life of the optical detection element.

[0063] In combination with the fourth aspect, in an optional implementation of the embodiment of the present application, the light detection element includes at least one of an ultraviolet sensor and an infrared sensor.

[0064] The technical effects obtained by the above-mentioned third and fourth aspects are similar to the technical effects obtained by the corresponding technical means in the first and second aspects, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0074] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0075] Clothes processing equipment is an indispensable device in daily life. It can perform such treatments as washing, dehydrating, drying, and caring for clothes, greatly improving the convenience of clothing processing. With the development of technology and the increase in user needs, the processing accuracy of clothes by clothing processing equipment has also improved. Taking washing machines as an example, current washing machines usually identify the material of clothes before processing them, so that clothes of different materials can use different processing parameters, which helps to improve the processing effect of clothes.

[0076] Material recognition methods include video recognition, which uses a camera to take a picture of the clothing and then uses an image algorithm to analyze the material of the clothing from the clothing image.

[0077] However, in actual use, it is found that camera recognition is often affected by factors such as ambient brightness and water mist, resulting in poor clarity of the captured clothing images and reduced accuracy in identifying clothing materials.

[0078] Based on this, the present application embodiment provides a method for identifying clothing material. Figure 1 The flowchart of the clothing material identification method shown in FIG. 1 includes the following processing steps.

[0079] S100: Acquire a plurality of diffuse reflection parameter values ​​when clothing diffusely reflects an incident light signal.

[0080] When identifying the material of clothing, an incident light signal is emitted to the clothing, and after the incident light signal contacts the clothing, it either transmits through the clothing or diffusely reflects after contacting the clothing. This embodiment only obtains the diffuse reflection parameter value generated after diffuse reflection occurs.

[0081] It should be noted that the diffuse reflection parameter value may be a parameter value of the reflected light signal itself after diffuse reflection occurs, such as the wavelength and light intensity of the reflected light signal, or may be a parameter value obtained after calculating the parameters of the reflected light signal itself, such as substituting the wavelength and / or light intensity of the reflected light signal into a preset calculation formula to obtain the diffuse reflection parameter value. In general, as long as different clothing materials can correspond to different diffuse reflection parameter values, it will be fine.

[0082] S102: Determine the clothing material of the clothing according to a plurality of diffuse reflection parameter values ​​and a correspondence between preset clothing materials and diffuse reflection standard value intervals.

[0083] In one embodiment of the present application, diffuse reflection may be generated after the light signal contacts the clothing, and then the diffuse reflection parameter value may be obtained.

[0084] Specifically, the diffuse reflection parameter value may be a parameter value of the reflected light signal itself after diffuse reflection occurs, such as the wavelength and light intensity of the reflected light signal, or may be a parameter value obtained by calculating the parameter value of the reflected light signal itself, such as substituting the wavelength and / or light intensity of the reflected light signal into a preset calculation formula to obtain the diffuse reflection parameter value. In general, as long as different clothing materials can correspond to different diffuse reflection parameter values, it will be fine.

[0085] In one embodiment, the preset calculation formula for calculating the diffuse reflection parameter value can be a formula including the wavelength and light intensity of the reflected light signal, for example, the diffuse reflection parameter value a = (wavelength λ-absorbed wavelength △E) / wavelength λ*φluminous flux*power factor (related to light intensity).

[0086] In one embodiment, in order to determine the material of clothing, a diffuse reflection standard value interval is preset, and different diffuse reflection standard value intervals correspond to different clothing materials, that is, there is a corresponding relationship between the diffuse reflection standard value interval and the clothing material.

[0087] Specifically, the diffuse reflection standard value interval is a numerical interval composed of diffuse reflection standard values. It should be noted that the diffuse reflection standard value and the diffuse reflection parameter value are of the same type or are obtained using the same algorithm. The difference is that the diffuse reflection standard value is a parameter value obtained by performing a diffuse reflection experiment on the clothing when the clothing material is known, while the diffuse reflection parameter value is a parameter value obtained by performing diffuse reflection on the clothing when the clothing material is actually identified. For ease of understanding, for example, during testing, the wavelength and light intensity of the reflected light signal after diffuse reflection are calculated using formula A to obtain the diffuse reflection standard value. After multiple tests on clothing of material a, a numerical interval P1 can be divided according to all the obtained diffuse reflection standard values. When actually identifying the clothing material, the wavelength and light intensity of the reflected light signal after diffuse reflection are also calculated using formula A to obtain the diffuse reflection parameter value. Since the calculation process of the diffuse reflection parameter value is the same as that of the diffuse reflection standard value, the clothing material of the clothing can be determined according to the diffuse reflection parameter value.

[0088] The correspondence between the diffuse reflection standard value interval and the clothing material is: each type of clothing material corresponds to a diffuse reflection standard value interval, and different types of clothing materials correspond to different diffuse reflection standard value intervals. For example, material a corresponds to the diffuse reflection standard value interval P1, which is the correspondence. So that when the diffuse reflection parameter value is within P1, it can be determined that the clothing material of the clothing is a. Preferably, the correspondence obtained by testing with an ultraviolet sensor and using the formula includes: the material tested at 100-130 is cotton, the material tested at 135-155 is linen, the material corresponding to 190-230 is wool, the material corresponding to 165-189 is silk, the material corresponding to 290-330 is polyester fiber, and the material corresponding to 335-390 is chemical fiber.

[0089] In this embodiment, since the light signal is used to detect the material of the clothing, the detection accuracy is not easily affected by water mist, and there is no need for autofocus, which helps to improve the recognition accuracy of the clothing material. In addition, the diffuse reflection of the incident light signal is used to detect the clothing, and there is no need to penetrate the clothing for detection, so it is not easy to have the defect of being unable to detect due to the inability of the incident light signal to penetrate the clothing, which further ensures the smooth recognition of the clothing material and helps to improve the recognition accuracy of the clothing material.

[0090] In a possible embodiment of the present application, Figure 2 As shown, a plurality of diffuse reflection parameter values ​​are obtained when the clothing diffusely reflects the incident light signal, including:

[0091] S200, controlling the emitter of the light detection element to transmit incident light signals to the clothes covering the light detection element for multiple times.

[0092] The multiple transmissions of the incident light signal may be performed by presetting the time interval between each transmission of the incident light signal, or the total number of transmissions of the incident light signal may be presetting, which is not specifically limited in this embodiment. For example, the incident light signal is transmitted 10 times in total, each time at an interval of 10 ms.

[0093] S202, receiving, through the light detecting element, a plurality of times, reflected light signals resulting from diffuse reflection of the incident light signals by the clothing.

[0094] Each incident light signal obtains a reflected light signal after being diffusely reflected by the clothing, that is, the incident light signal corresponds to the reflected light signal one by one, so the number of incident light signals emitted is equal to the number of reflected light signals.

[0095] S204: Perform data conversion processing based on the wavelength and / or light intensity of the reflected light signal received multiple times in the light detection element to obtain multiple diffuse reflection parameter values.

[0096] The specific data conversion process is not limited in this embodiment and can be determined according to actual needs. For ease of understanding, in an application scenario, after the wavelength and light intensity of the reflected light signal are substituted into a preset formula, the calculated result is the diffuse reflection parameter value, and the calculation process is the data conversion process.

[0097] By adopting this embodiment, when identifying the clothing material of clothing, the incident light signal will be emitted multiple times, so that the reflected light signal is received a very large number of times. Then it is converted to obtain multiple diffuse reflection parameter values. On the one hand, compared with one diffuse reflection parameter value, multiple diffuse reflection parameter values ​​are conducive to avoiding special situations and improving the accuracy of the clothing material of clothing identified based on the diffuse reflection parameter value. On the other hand, the wavelength, light intensity and other information of the reflected light signal are not directly used, but data conversion processing is performed, so that the diffuse reflection standard value intervals corresponding to different clothing materials have large differences, which is conducive to improving the accuracy of clothing material identification and avoiding the phenomenon of non-recognition due to the small difference in the diffuse reflection standard value intervals corresponding to different clothing materials.

[0098] Optionally, in an implementation of this embodiment, the light detecting element is an ultraviolet sensor or an infrared sensor, and the emitter and the receiver of the light detecting element are arranged in parallel and flatly below the clothing.

[0099] The parallel laying means that the transmitter and the receiver are arranged side by side and laid flat under the clothes.

[0100] With this embodiment, the ultraviolet sensor or infrared sensor is low-cost and is not likely to cause damage to clothing and the human body. The parallel and flatly arranged emitter and receiver are conducive to reducing the space occupied by the light detection element and improving the installation convenience of the light detection element.

[0101] Optionally, in an implementation of this embodiment, as Figure 3 As shown, the clothing material of the clothing is determined according to the correspondence between the plurality of diffuse reflection parameter values ​​and the preset clothing material and the diffuse reflection standard value interval, including:

[0102] S300: Determine a representative value according to a plurality of diffuse reflection parameter values.

[0103] Representativeness can be representativeness in any aspect, or in other words, representativeness from any angle. This embodiment does not make specific limitations on this, and can be determined according to actual needs, and the actual needs are related to the specific way of obtaining the diffuse reflection parameter value and / or the specific process of determining the corresponding relationship. For example, in the process of calculating the diffuse reflection parameter value, only simple algorithms such as addition, subtraction, multiplication and division are used, and the wavelength and light intensity of the reflected light signal are embodied by a constant. When determining the representative value, the average value of multiple diffuse reflection parameter values ​​can be used as the representative value. For another example, when determining the corresponding relationship, the larger value or the maximum value of the diffuse reflection standard value is used, and the representative value is the maximum value of multiple diffuse reflection parameter values.

[0104] S302: Compare the representative value with each diffuse reflection standard value interval to determine the diffuse reflection standard value interval to which the representative value belongs.

[0105] That is, it is determined in which diffuse reflection standard value interval the representative value is located. If it is located in the diffuse reflection standard value interval P1, the representative value belongs to P1; if it is located in P2, the representative value belongs to P2.

[0106] S304: Determine the clothing material corresponding to the diffuse reflection standard value interval to which the representative value belongs as the clothing material of the clothing according to the corresponding relationship.

[0107] Since there is a corresponding relationship between clothing materials and diffuse reflection standard value intervals, that is, clothing material a corresponds to diffuse reflection standard value interval P1, clothing material b corresponds to diffuse reflection standard value interval P2, clothing material c corresponds to diffuse reflection standard value interval P3, and so on. Therefore, after determining the diffuse reflection standard value interval to which the representative value belongs, the clothing material can be determined according to the corresponding relationship, and the clothing material of the clothing can be determined as the material.

[0108] According to this embodiment, the material of the clothing is determined based on the diffuse reflection standard value interval to which the representative value determined by the plurality of diffuse reflection parameter values ​​belongs, which helps to improve the accuracy.

[0109] Optionally, in an implementation of this embodiment, the representative value includes at least one of a maximum value, a minimum value, a middle value and an average value.

[0110] In this embodiment, no matter the maximum value, minimum value, intermediate value or average value, they are all representative in certain circumstances, so that the representative value can better reflect the characteristics or features of multiple diffuse reflection parameter values, thereby making the accuracy of the clothing material determined according to the representative value higher.

[0111] Optionally, in an implementation of this embodiment, the method further includes:

[0112] After obtaining the plurality of diffuse reflection parameter values, determining the validity of the plurality of diffuse reflection parameter values ​​according to the stability of the plurality of diffuse reflection parameter values, wherein the validity includes valid and invalid;

[0113] If the plurality of diffuse reflection parameter values ​​are valid, determining the clothing material of the clothing according to the correspondence between the plurality of diffuse reflection parameter values ​​and the preset clothing material and diffuse reflection standard value interval;

[0114] If the plurality of diffuse reflection parameter values ​​are invalid, the spatial distribution state of the clothing is changed according to the clothing adjustment strategy and the plurality of diffuse reflection parameter values ​​are reacquired when the clothing diffusely reflects the incident light signal.

[0115] That is, after obtaining a plurality of diffuse reflection parameter values, their validity will be judged first, and the clothing material of the clothing will be determined using the valid plurality of diffuse reflection parameter values.

[0116] Among them, stability refers to the stability of multiple diffuse reflection parameter values. When evaluating stability, it can be evaluated from the perspective of the difference between the multiple diffuse reflection parameter values, or from the perspective of the fluctuation of the multiple diffuse reflection parameter values. This embodiment does not make specific limitations on this.

[0117] In the case where multiple diffuse reflection parameter values ​​are invalid, the spatial distribution state of the clothing will be adjusted first, and then the multiple diffuse reflection parameter values ​​will be re-acquired. It should be noted that the clothing adjustment strategy is intended to change the spatial distribution state of the clothing, so this embodiment does not specifically limit this. For ease of understanding, for example, the clothing adjustment strategy can be to adjust the position of the clothing, and the specific adjustment method can be determined according to the actual situation.

[0118] With this embodiment, the validity of multiple diffuse reflection parameter values ​​will be judged. Only when the multiple diffuse reflection parameter values ​​are valid, the clothing material of the clothing will be determined based on the multiple diffuse reflection parameter values ​​and the corresponding relationship, thereby ensuring the accuracy of the determined clothing material. For invalid multiple diffuse reflection parameter values, the multiple diffuse reflection parameter values ​​will be re-acquired. Since re-acquisition also belongs to the case of acquiring multiple diffuse reflection parameter values, the validity will be determined again, and so on, to achieve a cyclic processing, which is helpful to improve the accuracy of the determined clothing material.

[0119] Optionally, in an implementation of this embodiment, determining the validity of the plurality of diffuse reflection parameter values ​​according to the stability of the plurality of diffuse reflection parameter values ​​includes:

[0120] The validity of the plurality of diffuse reflection parameter values ​​is determined according to the discreteness of the plurality of diffuse reflection parameter values, wherein the discreteness is used to characterize the stability of the plurality of diffuse reflection parameter values.

[0121] According to this embodiment, when determining the validity of a plurality of diffuse reflection parameter values, the validity is determined according to the discreteness of the plurality of diffuse reflection parameter values. This simplifies the calculation process and helps to reduce the occupation of computing resources.

[0122] Optionally, in an implementation of this embodiment, determining the validity of the plurality of diffuse reflection parameter values ​​according to the discreteness of the plurality of diffuse reflection parameter values ​​includes:

[0123] Calculate the average of multiple diffuse reflection parameter values;

[0124] The standard deviation representing the degree of dispersion is calculated using the average value and multiple diffuse reflection parameter values;

[0125] If the standard deviation exceeds a preset validity threshold, the multiple diffuse reflection parameter values ​​are determined to be invalid;

[0126] If the standard deviation does not exceed the valid threshold, the plurality of diffuse reflectance parameter values ​​are determined to be valid.

[0127] The effective threshold value can be obtained through experiments. Specifically, when determining the corresponding relationship, in order to make each diffuse reflection standard value interval not overlap with each other, the standard deviation of multiple diffuse reflection parameter values ​​in the experiment is calculated, and the formation of the diffuse reflection standard value interval is constrained by the standard deviation, thereby determining the effective threshold value. The specific determination process of the effective threshold value is not limited in this embodiment.

[0128] By adopting this embodiment, the discreteness of multiple diffuse reflection parameter values ​​is measured by standard deviation, and the calculation process is simple, which helps to reduce the occupation of computing resources.

[0129] Optionally, in an implementation of this embodiment, the clothes are located in the clothes processing drum, and the spatial distribution state of the clothes is changed according to the clothes adjustment strategy, including:

[0130] Control the laundry processing drum to rotate to a preset angle.

[0131] It should be noted that the clothing adjustment strategy includes a preset angle and may also include the rotation direction and number of rotations of the clothing treatment drum.

[0132] By adopting this embodiment, the control process is simple and quick, which is conducive to improving the efficiency of clothing material recognition.

[0133] Optionally, in an implementation of this embodiment, after controlling the laundry processing drum to rotate by a preset angle, the method further includes:

[0134] The rotation of the laundry processing drum is controlled according to the preset dithering parameters, so as to re-acquire a plurality of diffuse reflection parameter values ​​when the laundry diffusely reflects the incident light signal after the laundry processing drum stops rotating.

[0135] The shaking parameters include the rotation speed of the laundry treatment drum and the number of reciprocating rotations. Specifically, in one application scenario, when the laundry treatment drum is controlled to rotate according to the shaking parameters, the laundry treatment drum is first controlled to rotate forward and then reversed to achieve reciprocating rotation. It should be noted that the position of the laundry treatment drum before rotating according to the shaking parameters is the same as the position after stopping rotating.

[0136] By adopting this embodiment, after running the shaking parameters, it is beneficial to change the state and arrangement order of the clothes in the clothing processing drum, so that the re-acquired multiple diffuse reflection parameter values ​​are not likely to be the same as or have a high degree of similarity with the previously acquired ones, which helps to increase the difference between the previously acquired and re-acquired multiple diffuse reflection parameter values, so that the re-acquired multiple diffuse reflection parameter values ​​are easy to be determined as valid, thereby reducing the number of times multiple diffuse reflection parameter values ​​are acquired and improving the clothing material recognition efficiency of the clothes.

[0137] This embodiment also provides a control method for a clothes processing device, including:

[0138] The clothing material identification method described above is used to identify the clothing material of the clothing in the clothing processing drum.

[0139] The clothing processing device is controlled to execute corresponding operating parameters according to the clothing material of the clothing.

[0140] Among them, the operating parameters can be the operating mode that the clothing processing device needs to run, or the operating time, operating temperature, operating speed and other parameters of a certain operating mode, which are not specifically limited in this embodiment.

[0141] In this embodiment, when the clothing processing device is used, the above-mentioned clothing material identification method will be used to identify the clothing material of the clothing in the clothing processing device. After obtaining the clothing material of the clothing, the corresponding operating parameters will be executed according to the clothing material of the clothing, so that when the clothing processing device processes the clothing, different operating parameters will be executed for different types of clothing materials, which is conducive to improving the processing effect of the clothing.

[0142] Optionally, in an implementation of this embodiment, the method further includes:

[0143] When the number of times of identifying the material of the clothes in the clothes processing drum reaches a preset number threshold, the identification is stopped.

[0144] It should be noted that each time multiple diffuse reflection parameter values ​​are obtained, it is considered that the clothing material is identified once. The number of identifications can be limited by the number threshold to prevent the clothing processing device from staying in the clothing material identification stage for a long time when multiple diffuse reflection parameter values ​​obtained multiple times are always invalid.

[0145] By adopting this embodiment and setting a number threshold, the number of times the clothing material is identified can be limited, so that the clothing processing device will not be in the clothing material identification stage for a long time, which is beneficial to improving the clothing processing efficiency of the clothing processing device.

[0146] This embodiment also provides an electronic device, the electronic device includes a memory and a processor;

[0147] Memory for storing computer programs;

[0148] The processor is used to execute the computer program to implement the steps of the above method.

[0149] This embodiment also provides a clothes processing device, comprising a clothes processing drum that can be controlled to rotate, and a light detection element 2 is provided on the clothes processing drum;

[0150] The clothing processing device adopts the above-mentioned clothing material identification method to identify the clothing material, or the clothing processing device also includes the above-mentioned electronic device.

[0151] The optical detection element 2 refers to a device that can emit a light signal, and the light signal can be diffusely reflected by clothing, and can also realize material recognition based on the reflected light signal after diffuse reflection. Specifically, the optical detection element 2 includes at least one of an ultraviolet sensor and an infrared sensor.

[0152] Optionally, in an implementation of this embodiment, as Figure 4 As shown, at least one lifting rib 1 is provided on the laundry processing drum, a receiving groove 11 is provided in the at least one lifting rib 1 , and the light detecting element 2 is located in the receiving groove 11 .

[0153] The lifting rib 1 extends from the inner wall of the laundry treatment drum to the inside of the laundry treatment drum and has a certain height. The lifting rib 1 can be integrally formed with the laundry treatment drum, or can be connected to the inner wall of the laundry treatment drum by welding, screwing, etc. For ease of understanding, along the extension direction of the lifting rib 1, the surface of the lifting rib 1 close to the inner center of the laundry treatment drum is the upper end surface of the lifting rib 1, and the accommodating groove 11 is opened from the upper end surface toward the inner wall of the laundry treatment drum.

[0154] In this embodiment, a receiving groove 11 is provided on the lifting rib 1 for mounting the optical detection element 2, so that the optical detection element 2 is not easily entangled with the clothes in the clothes processing drum, and thus the optical detection element 2 is not easily affected by the movement of the clothes in the clothes processing drum. At the same time, the optical detection element 2 is located in the lifting rib 1, and the distance between the optical detection element 2 and the clothes can be changed as the position of the lifting rib 1 changes, which is conducive to improving the detection of the clothes by the optical detection element 2 and improving the detection quality.

[0155] Optionally, in one implementation of the present embodiment, the optical detection element 2 includes an emitter 21 and a receiver 22, which are arranged in a parallel and flat manner in the receiving groove 11, the emitter 21 is used to emit an incident light signal into the clothing processing drum, and the receiver 22 is used to receive a reflected light signal after the clothing in the processing drum reflects the incident light signal.

[0156] Optionally, in an implementation of this embodiment, the emitter 21 and the receiver 22 are arranged in sequence along the rotation direction of the laundry processing drum and are parallel to each other;

[0157] There is a distance between the end faces of the emitter 21 and the receiver 22 and the upper end face of the lifting rib 1 .

[0158] The distance is, for example, 20 mm or 15 mm, which is not specifically limited in this embodiment, and is intended to improve the detection accuracy of the light detection element 2 by setting the distance.

[0159] In this embodiment, the optical detection element 2 is installed at a certain distance, so that when the clothes cover the upper end surface of the lifting rib 1, there is still a distance between the clothes and the optical detection element 2, which helps to improve the detection quality of the optical detection element 2.

[0160] Optionally, in an implementation of the present embodiment, a cover plate for sealing the accommodating groove 11 is provided on the lifting rib 1, and the cover plate is a waterproof and light-transmitting plate.

[0161] In this embodiment, by providing a cover plate, the receiving groove 11 is sealed so that the water in the laundry treatment drum does not enter the receiving groove 11, thereby protecting the optical detection element 2 from water ingress or soaking, thereby increasing the service life of the optical detection element 2.

[0162] In the above-mentioned embodiments of the present application, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments. The steps shown in the relevant flow chart can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flow chart, in some cases, the steps shown or described can be executed in an order different from that here. In other words, the order of steps described in the foregoing embodiments is only an example, and it is also within the scope of protection of the embodiments of the present application to reasonably adjust the order of steps based on the content of the embodiments of the present application.

[0163] In a specific implementation of the embodiment of the present application, Figure 4 and 5 As shown in the figure, the clothing material recognition method is generally described.

[0164] In this specific implementation, the light detection element 2 uses an ultraviolet sensor, and the emitter 21 and the receiving electrode 22 of the ultraviolet sensor are installed in a flat manner inside the lifting rib 1. The distance between the emitter 21 and the receiving electrode 22 of the sensor and the top of the lifting rib 1 (i.e., where the clothes are placed) is 10 / 15 / 20mm, etc. The relevant working principle is: the ultraviolet emitter 21 emits ultraviolet rays, and the multiple beams emitted are emitted in a horizontal direction and contact the material to be tested. The material to be tested absorbs ultraviolet rays of different intensities according to the knitting density of different materials. The remaining ultraviolet rays that are not absorbed are reflected back to the receiving electrode 22 after contacting the surface of this material. The light intensity received by the receiving electrode 22 is the remaining unabsorbed ultraviolet rays. After the sensor receives the light intensity, the MCU chip of the PCB board processes the electrical signal and converts it into a digital signal. The finally obtained measured parameters are then compared by the control method to determine what material the measured clothes are made of.

[0165] Principle description:

[0166] The wavelength of the ultraviolet spectrum used is 100-400nm. The absorbed wavelength is calculated according to quantum theory as △E=hv=hc / . The program can calculate the emitted wavelength and the wavelength received after diffuse reflection through further data processing algorithms. The following control method requires the use of standard deviation and average value comparison to collect 10 values ​​compared to the average value. When the standard deviation and the degree of deviation are small, the average value is compared with the preset value to determine the specific range and determine the material.

[0167] Parameter Description:

[0168] like Figure 5As shown in the figure, △a is the range obtained by converting the specific wavelength of the corresponding fixed material through the above formula and then taking the derivative, a is the average value after sampling 10 times, and the standard deviation is the stable value after comparing each sampled value with the average value. Not only △a, different materials correspond to different preset value intervals.

[0169] The method includes the following processing steps:

[0170] Put the clothes into the drum, and the drive motor of the rear drum starts to weigh and detect the changes in the clothes in the drum. The current of the drive motor changes, confirming that there are clothes in the drum. At this time, the main board sends an electrical signal to the ultraviolet sensor inside the lifting rib 1. The sensor starts to power on and detect the material. It captures data every 2 seconds, for a total of 10 times. The 10 data are a group, and the average value a of this group is calculated, as well as the standard deviation of each data. The difference in the degree of deviation between the 10 captured data and the average value is verified. If the standard deviation and the average value a are large, it means that the deviation range of the 10 measured data and the average value is large, which proves that the detected material may be a variety of materials. At this time, it is necessary to adjust the detection angle of the lifting rib 1 sensor. At this time, it is necessary to power the drive motor to adjust the angle. The first time, the drum is rotated forward by an angle α (60°), and the forward and reverse rotation is performed at a low speed of 50r / min. The cradle wash (i.e., the running shaking parameters) is performed to shake the clothes to a certain extent. The stacking state of the clothes varies within a certain range. After rotating for 1 minute, it stops rotating. The ultraviolet sensor in the lifting rib 1 detects the relationship between the standard deviation and the average value a again. If the standard deviation data is small, there is no need to control the rotation angle of the drive motor, and directly go to the next step to compare the average value a with the preset interval △a. If the standard deviation data is still too large, it is necessary to drive the motor to rotate by an angle β (120°) and rotate the inner drum back and forth at a low speed of 60r / min to perform cradle washing to shake out the clothes to a certain extent.

[0171] Compare the average value a with the closest preset value △a to see if the average value is outside the interval or within the range. If it is within the range, determine the material based on the corresponding interval preset by the big data of the main control board. If it is outside the range, the reflection angle of the sensor diffuse reflection is deviated, and feedback is given to the main control board. After the main control board receives the feedback, it further controls the motor to rotate at an angle α, and the motor rotates forward and reverse at a low speed to wash the cradle for 1 minute and then stops rotating. Then compare the average value a with the preset interval △a. If it is still outside the interval, the drive motor is adjusted at an angle β, and the motor rotates forward and reverse at a low speed to wash the cradle for 1 minute and then stops rotating. Then compare the average value a with the preset interval △a. By analogy, the sensor test accuracy can be improved by adjusting the motor angle.

[0172] The function and reason of cradle washing: The cradle washing program will shake out the clothes in the drum to a certain extent to prevent accumulation.

[0173] When the standard deviation and average value of the test are finally determined to meet the judgment requirements, the next step is to adjust the washing mode for clothes of different materials. For example, if it is determined to be cotton, the number of rinses will be increased accordingly to prevent detergent residue, the spin speed will be reduced to prevent wrinkles from getting worse, and the spin time will be extended after the speed is reduced.
