Description

Technical Field

[0001] This invention relates to the field of garment processing equipment technology, and in particular to a material testing method, a material testing device, an electronic device, and a garment processing device. Background Technology

[0002] In clothing material detection technologies, camera sampling technology is generally used. Smart camera identification of clothing material is a technology that integrates image recognition technology, deep learning algorithms and expert systems. However, camera sampling technology relies on deep learning algorithms and expert systems to determine clothing material, resulting in low accuracy in clothing material detection.

[0015] In some embodiments, in the first detection mode, the clothing processing drum is illuminated with colored light, and in the second detection mode, the color of the light inside the clothing processing drum is different from that in the first detection mode.

[0016] In some embodiments, under the first detection mode, the color illumination is red illumination.

[0017] In some embodiments, in the first detection mode

[0018] The optical signal detection device is controlled to repeatedly acquire optical signals multiple times. Each optical signal corresponds to a first sub-parameter value, and multiple first sub-parameter values ​​form a first parameter value group.

[0019] The optical signal detection device is controlled to acquire multiple sets of the first parameter values, and the first parameter value is calculated based on the multiple sets of the first parameter values.

[0020] And / or in the second detection mode,

[0021] The optical signal detection device is controlled to repeatedly acquire optical signals multiple times. Each optical signal corresponds to a second sub-parameter value, and multiple second sub-parameter values ​​form a second parameter value group.

[0022] The optical signal detection device is controlled to acquire multiple sets of the second parameter values, and the second parameter value is calculated based on the multiple sets of the second parameter values.

[0023] In some embodiments, calculating the first parameter value based on a plurality of first parameter value groups includes:

[0024] In the first parameter value group, the average of the sum of the plurality of first sub-parameter values ​​is calculated as the average of the first parameter value group;

[0025] The median of the average values ​​of multiple groups of the first parameter values ​​is selected as the first parameter value;

[0026] The step of calculating the second parameter value based on multiple sets of second parameter values ​​includes:

[0027] In the second parameter value group, the average of the sum of the plurality of second sub-parameter values ​​is calculated as the average of the second parameter value group;

[0028] The median of the average of multiple sets of the second parameter values ​​is selected as the second parameter value.

[0029] In some embodiments, a material testing device is provided, disposed inside the garment processing drum of a garment processing device, comprising:

[0030] There are n optical signal detection devices, each of which includes an emitter and a receiver, where n ≥ 2;

[0031] A lamp body, the lamp body being used to irradiate colored light into the garment processing drum;

[0032] The n optical signal detectors are configured such that the emitter of any one of the n optical signal detectors emits an optical signal into the clothes in the clothes processing drum, and the receiver of any one of the optical signal detectors receives the optical signal reflected from the clothes in the clothes processing drum.

[0033] In some embodiments, the material testing device further includes:

[0034] There are n lifting ribs, each corresponding to one of the n optical signal detection devices. The emitter and receiver in the same optical signal detection device are laid flat on the corresponding lifting rib.

[0041] The solution provided by this invention has the following advantages compared with the prior art:

[0042] This method for detecting clothing materials includes a first detection mode and a second detection mode. In the second detection mode, the clothing processing drum is illuminated with a different color of light than in the first detection mode. This causes the clothing inside the drum to be covered by a different light color than in the first detection mode. Different clothing materials have different reflectivity to the light signals emitted by the light signal detection device under different light color environments. Consequently, the second parameter value obtained by the light signal detection device differs from the first parameter value. This difference is used to obtain the final parameter value. By changing the detection environment and utilizing the parameter differences under different environments, this material detection method can eliminate certain uncertainties affecting the detection results, thereby achieving a more accurate detection effect. This provides more precise data for subsequently selecting appropriate washing modes for different clothing materials. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0051] In clothing material detection technologies, camera sampling technology is generally used. Smart camera identification of clothing material is a technology that integrates image recognition technology, deep learning algorithms and expert systems. However, camera sampling technology relies on deep learning algorithms and expert systems to determine clothing material, resulting in low accuracy in clothing material detection.

[0052] Based on this, the following embodiments are proposed.

[0053] Example 1:

[0054] like Figure 1 As shown, this embodiment provides a material detection method for identifying the material of clothing inside the clothing processing drum of a clothing processing device. The material detection method includes:

[0055] First detection mode and second detection mode.

[0056] The first parameter value characterizing the material of the clothing is obtained. The first parameter value is determined based on the light signal collected by the light signal detector in the first detection mode.

[0057] A second parameter value characterizing the material of the clothing is obtained. The second parameter value is determined based on the light signal collected by the light signal detector in the second detection mode.

[0058] Obtain the final parameter value that characterizes the material of the clothing. The final parameter value is determined by the first parameter value and the second parameter value. Determine the preset target range in which the final parameter value is located. Determine the material of the clothing based on the correspondence between the preset target range and the material of the clothing.

[0059] In the second detection mode, the color of the light inside the garment processing drum is different from that in the first detection mode.

[0060] In this embodiment, the method for detecting clothing material consists of a first detection mode and a second detection mode. The difference between the second and first detection modes is that in the second detection mode, the clothing processing tube has a different light color than in the first detection mode. Both detection modes obtain relevant parameter values ​​through light signals collected by a light signal detection device. Because the clothing processing tube has a different light color in the second detection mode than in the first detection mode, the clothing in the clothing processing tube is covered with a different light color than in the first detection mode. Different clothing materials have different reflectivity to the light signals emitted by the light signal detection device under different light color environments. Therefore, there is a certain difference between the second parameter value and the first parameter value obtained by the light signal detection device. Using this difference, a final parameter value is obtained. Finally, by judging the preset target range in which the final parameter value is located, the clothing material is determined according to the correspondence between the preset target range and the clothing material. Compared with single image recognition or repeated parameter acquisition under the same environment, this material detection method can eliminate certain uncertainties affecting the detection results by changing the detection environment and utilizing the parameter differences under different environments, thereby achieving a more accurate detection effect. This will provide more accurate data for selecting the appropriate washing mode for different types of clothing.

[0061] Optionally, in one implementation of this embodiment, such as Figure 1 As shown,

[0062] The first parameter is a1, the second parameter is a2, and the final parameter is a1. △ a,

[0063] in, △ a=∣a2-a1∣.

[0064] More specifically, there is a certain difference between the second parameter value and the first parameter value obtained by the optical signal detection device. Using this difference, the final parameter value is obtained, that is, the final parameter value is the absolute value of the difference between the second parameter value and the first parameter value. The calculation method is simple. By judging the preset target interval in which the final parameter value is located, the clothing material is determined according to the correspondence between the preset target interval and the clothing material. Compared with single image recognition or repeated parameter acquisition under the same environment, this material detection method can eliminate certain uncertain factors affecting the detection results by changing the detection environment and using the parameter difference under different environments, thereby achieving a more accurate detection effect.

[0065] For example, in the first detection mode, six first parameter values, a1 to f1, are obtained through the optical signal detection device. These six first parameter values ​​correspond to six types of clothing materials. Among them, a1 to f1 can be data obtained from multiple acquisitions and processed. Multiple acquisitions refer to the parameter values ​​collected by the optical signal detection device at certain time intervals. After each acquisition of parameter values ​​by the optical signal detection device, the clothing processing drum is shaken once, thereby ensuring the comprehensiveness of clothing material detection. In the second detection mode, six second parameter values ​​(a2 to f2) are acquired through the optical signal detector. These six second parameter values ​​correspond to the same six types of clothing materials detected in the first detection mode. The final parameter value is obtained by subtracting the corresponding first parameter value from the second parameter value. If there is an error between the preset target range corresponding to the first parameter value obtained in the first detection mode and the actual material, but no error in the preset target range corresponding to the second parameter value obtained in the second detection mode, the two parameter values ​​cannot be subtracted, and a re-detection is required. Conversely, if there is an error between the preset target range corresponding to the second parameter value obtained in the second detection mode and the actual material, but no error in the preset target range corresponding to the first parameter value obtained in the first detection mode, it will lead to... Since the two parameter values ​​cannot be subtracted, a retest is required. Only when the preset target intervals corresponding to both the first and second test modes are error-free with respect to the actual material can the final parameter value be obtained. This further ensures the accuracy of the final parameter value, making the final test result more accurate. Finally, six corresponding final parameter values ​​are obtained: △a=|a2-a1|~△f=|f2-f1|. The preset target intervals containing the final parameter values ​​△a~△f are determined. Based on the correspondence between the preset target intervals and the clothing material, the clothing material is determined. The preset target intervals corresponding to △a~△c are all cotton, △d and △e are all linen, and △f is all silk. In this case, cotton accounts for 50%, linen for 33%, and silk for 17%. Therefore, the selectable washing mode is the cotton-linen washing mode.

[0066] Optionally, in one implementation of this embodiment, such as Figure 2 As shown,

[0067] The number of optical signal detection devices is n, n≥1. The n optical signal detection devices are distributed sequentially along the circumference of the clothing processing drum in the clothing processing equipment. Each optical signal detection device includes an emitter and a receiver.

[0068] The first detection mode and / or the second detection mode include: controlling the emitter of any one of the n optical signal detectors to emit an optical signal into the clothes in the clothes processing drum, and controlling the receiver of any one of the optical signal detectors to receive the optical signal reflected from the clothes in the clothes processing drum.

[0069] In this embodiment, n=2, and the two optical signal detection devices include a first optical signal detection device and a second optical signal detection device. The first optical signal detection device includes a first emitter 201 and a first receiver 301, and the second optical signal detection device includes a second emitter 202 and a second receiver 302.

[0070] Obtaining the first parameter value characterizing the material of the clothing includes controlling the first emitter 201 and the second emitter 202 to emit light signals to the clothing in the clothing processing device, controlling the first receiver 301 to receive the light signals emitted by the first emitter 201 reflected by the clothing in the clothing processing drum, and controlling the second receiver 302 to receive the light signals emitted by the second emitter 202 reflected by the clothing in the clothing processing drum. The light signals emitted by the emitters pass through the clothing in the clothing processing drum. Part of the light signals are blocked and reflected by the clothing and received by the corresponding receiver, part of the light signals are absorbed by the clothing, and another part of the light signals penetrate the clothing. Different materials of clothing have different light signal reflection capabilities, thereby obtaining different first parameter values.

[0071] The method for obtaining the second parameter value representing the material of clothing is the same as the method for obtaining the first parameter value representing the material of clothing described above. The method for obtaining the first and second parameter values ​​representing the material of clothing is simple, easy to implement, and highly accurate.

[0072] Alternatively, in one implementation of this embodiment,

[0073] In the first detection mode, there is no light inside the garment processing drum; in the second detection mode, there is colored light inside the garment processing drum, or...

[0074] In the first detection mode, the garment processing drum is illuminated with colored light; in the second detection mode, the garment processing drum is not illuminated.

[0075] In the first detection mode, the garment processing drum is illuminated with colored light. In the second detection mode, the color of the light inside the garment processing drum is different from that in the first detection mode.

[0076] Preferably, in the first detection mode, there is no light inside the garment processing drum, while in the second detection mode, there is red light inside the garment processing drum. By installing a red light emitter inside the garment processing drum, the red light shines on the garments inside, thus achieving red light coverage inside the garment processing drum.

[0077] In the first detection mode, there is no light inside the garment processing drum. A first parameter value characterizing the garment material is acquired using a light signal detector. In the second detection mode, the garment processing drum is illuminated with red light. A second parameter value characterizing the garment material is acquired using the light signal detector. Under red light, the garment has different reflectivity to the light signal emitted by the light signal detector. Therefore, there is a difference between the second parameter value and the first parameter value acquired by the light signal detector. This difference is used to obtain the final parameter value. Finally, by determining the preset target range where the final parameter value falls, the garment material is determined based on the correspondence between the preset target range and the garment material. Compared to simple image recognition or repeatedly acquiring parameters under the same environment, this material detection method, by changing the detection environment and utilizing the parameter differences under different environments, can eliminate certain uncertainties affecting the detection results, thus achieving a more accurate detection effect. This provides more precise data for subsequently selecting appropriate washing modes for different garment materials.

[0078] It should be noted that, in one embodiment of this application, the light signal can generate diffuse reflection after coming into contact with clothing, thereby obtaining the diffuse reflection parameter value.

[0079] Specifically, the diffuse reflection parameter value can be the parameter value of the reflected light signal itself after diffuse reflection, such as the wavelength and intensity of the reflected light signal, or it can be a parameter value obtained by calculating the parameter value of the reflected light signal itself, such as substituting the wavelength and / or intensity of the reflected light signal into a preset calculation formula to obtain the diffuse reflection parameter value. In general, it is sufficient as long as different clothing materials correspond to different diffuse reflection parameter values.

[0080] In an embodiment, the preset calculation formula for calculating the diffuse reflection parameter value can be a formula that includes the wavelength and intensity of the reflected light signal. For example, the diffuse reflection parameter value a = (wavelength λ - absorbed wavelength ΔE) / wavelength λ * φ luminous flux * power factor (intensity related).

[0081] In this embodiment, in order to determine the material of the clothing, a standard range of diffuse reflection values ​​is preset. Different standard ranges of diffuse reflection values ​​correspond to different clothing materials. In other words, there is a correspondence between the standard range of diffuse reflection values ​​and the clothing material.

[0082] Specifically, the diffuse reflectance standard value range is a numerical range composed of diffuse reflectance standard values. It's important to note that diffuse reflectance standard values ​​and diffuse reflectance parameter values ​​are of the same type or obtained using the same algorithm. The difference lies in that diffuse reflectance standard values ​​are parameter values ​​obtained by conducting diffuse reflectance experiments on clothing with known material characteristics, while diffuse reflectance parameter values ​​are parameter values ​​obtained by conducting diffuse reflectance experiments on clothing during actual material identification. For ease of understanding, for example, during testing, formula A is used to calculate the wavelength and intensity of the reflected light signal after diffuse reflection to obtain the diffuse reflectance standard value. After multiple tests on clothing of material 'a', a numerical range P1 can be defined based on all the obtained diffuse reflectance standard values. In actual clothing material identification, formula A is also used to calculate the wavelength and intensity of the reflected light signal after diffuse reflection, thus obtaining the diffuse reflectance parameter value. Since the calculation process for the diffuse reflectance parameter value is the same as that for the diffuse reflectance standard value, the clothing material can be determined based on the diffuse reflectance parameter value.

[0083] The correspondence between diffuse reflectance standard value ranges and clothing materials is as follows: each type of clothing material corresponds to a diffuse reflectance standard value range, and different types of clothing materials correspond to different diffuse reflectance standard value ranges. For example, material 'a' corresponds to the diffuse reflectance standard value range P1; this is the correspondence. Therefore, when the diffuse reflectance parameter value is within P1, it can be determined that the clothing material is 'a'.

[0084] Alternatively, in one implementation of this embodiment,

[0085] In the first detection mode

[0086] The optical signal detection device is controlled to repeatedly acquire optical signals multiple times. Each optical signal corresponds to a first sub-parameter value, and multiple first sub-parameter values ​​form a first parameter value group.

[0087] The optical signal detection device is controlled to acquire multiple sets of the first parameter values, and the first parameter value is calculated based on the multiple sets of the first parameter values.

[0088] And / or in the second detection mode,

[0089] The optical signal detection device is controlled to repeatedly acquire optical signals multiple times. Each optical signal corresponds to a second sub-parameter value, and multiple second sub-parameter values ​​form a second parameter value group.

[0090] The optical signal detection device is controlled to acquire multiple sets of the second parameter values, and the second parameter value is calculated based on the multiple sets of the second parameter values.

[0091] Furthermore, the step of calculating the first parameter value based on a plurality of first parameter value groups includes:

[0092] In the first parameter value group, the average of the sum of the plurality of first sub-parameter values ​​is calculated as the average of the first parameter value group;

[0093] The median of the average values ​​of multiple groups of the first parameter values ​​is selected as the first parameter value;

[0094] The step of calculating the second parameter value based on multiple sets of second parameter values ​​includes:

[0095] In the second parameter value group, the average of the sum of the plurality of second sub-parameter values ​​is calculated as the average of the second parameter value group;

[0096] The median of the average of multiple sets of the second parameter values ​​is selected as the second parameter value.

[0097] In this embodiment, the first parameter value and / or the second parameter value are data processed by the above calculation. Taking the median after taking the mean of the grouped data can further detect the accuracy of the data and improve the accuracy of clothing material detection.

[0098] Example 2

[0099] like Figure 2 As shown, this embodiment provides a material testing device, which is installed inside the garment processing drum of a garment processing device, and includes:

[0100] There are n optical signal detection devices, each of which includes an emitter and a receiver, where n ≥ 2;

[0101] The lamp body is used to illuminate the garment processing drum with colored light.

[0102] The n optical signal detectors are configured such that the emitter of any one of the n optical signal detectors emits an optical signal into the clothes in the clothes processing drum, and the receiver of any one of the optical signal detectors receives the optical signal reflected from the clothes in the clothes processing drum.

[0103] In this embodiment, n=2, and the two optical signal detection devices include a first optical signal detection device and a second optical signal detection device. The first optical signal detection device includes a first emitter 201 and a first receiver 301, and the second optical signal detection device includes a second emitter 202 and a second receiver 302.

[0104] The first parameter value characterizing the material of the clothing is obtained by emitting light signals to the clothing in the clothing processing device through the first emitter 201 and the second emitter 202. The first receiver 301 is controlled to receive the light signal emitted by the first emitter 201 reflected by the clothing in the clothing processing drum, and the second receiver 302 is controlled to receive the light signal emitted by the second emitter 202 reflected by the clothing in the clothing processing drum. The light signal emitted by the emitter passes through the clothing in the clothing processing drum. Part of the light signal is blocked and reflected by the clothing and received by the corresponding receiver, part of the light signal is absorbed by the clothing, and another part of the light signal penetrates the clothing. Different materials of clothing have different light signal reflection capabilities, thus obtaining different first parameter values.

[0105] The method for obtaining the second parameter value representing the material of clothing is the same as the method for obtaining the first parameter value representing the material of clothing. The method for obtaining the first and second parameter values ​​representing the material of clothing is simple and easy to implement. It is not only highly accurate, but also has a relatively simple structure for the optical signal detection device, making it suitable for use inside the clothing processing cylinder.

[0106] The lamp works to illuminate the clothes processing drum with colored light, which then shines on the clothes inside, thus covering the inside of the drum with colored light.

[0107] Optionally, in one implementation of this embodiment, such as Figure 2 , 3 As shown,

[0108] The material testing equipment also includes: n lifting ribs 1, each corresponding to one of the n optical signal detection components. The emitter and receiver in the same optical signal detection component are laid flat on the corresponding lifting rib 1.

[0109] In this embodiment, n=2. Using the lifting rib 1 as a carrier, the optical signal detection device can more fully utilize its detection effect. The two sides of the lifting rib 1 are open, providing effective passage space for the transmission and reception of optical signals during operation, preventing signal obstruction and thus ensuring better working conditions and more accurate detection results. The combination of the optical signal detection device and the lifting rib results in a relatively simple structure while improving the effectiveness and accuracy of clothing material detection.

[0110] Alternatively, in one implementation of this embodiment,

[0111] The optical signal detection device is a near-infrared sensor or an ultraviolet sensor;

[0112] When the optical signal detection device is a near-infrared sensor, the emitter is the emitter of the near-infrared sensor, and the receiver is the receiver of the near-infrared sensor.

[0113] When the optical signal detection device is an ultraviolet sensor, the emitter is the emitter of the ultraviolet sensor, and the receiver is the receiver of the ultraviolet sensor.

[0114] In this embodiment, when the optical signal detection device is a near-infrared sensor, the emitter is the emitter of the near-infrared sensor, and the emitter lamp can be turned on to irradiate red light into the clothing processing drum. The wavelength of the emitted light signal is 700-2500nm, and the preset target range includes 150±30nm, corresponding to cotton; 300±50nm, corresponding to linen; 450±70nm, corresponding to silk; 50±10nm, corresponding to wool; and 200±40nm, corresponding to polyester fiber.

[0115] When the optical signal detection device is an ultraviolet sensor, the emitter is the ultraviolet sensor emitter, and the wavelength of the emitted optical signal is 100-400nm. The preset target range includes 45±10nm, corresponding to cotton material; 80±15nm, corresponding to linen material; 120±20nm, corresponding to silk material; 15±5nm, corresponding to wool material; and 55±12nm, corresponding to polyester fiber material.

[0116] Example 3

[0117] This embodiment provides an electronic device, which includes:

[0118] Memory stores computer instructions;

[0119] The processor is used to call and execute computer instructions to implement the material detection method in Embodiment 1, or to call and execute computer instructions to control the material detection device in Embodiment 2 and implement the material detection method in Embodiment 1.

[0120] This electronic device acquires first and second parameter values ​​through a first detection mode and a second detection mode, and then obtains a final parameter value from these values. In the second detection mode, the light color inside the garment processing drum differs from that in the first detection mode, causing the garments inside to be covered by a different light color. Different garment materials have different reflectivity to the light signals emitted by the light signal detection device under different light colors. Therefore, there is a certain difference between the second and first parameter values ​​acquired by the light signal detection device. This difference is used to obtain the final parameter value. Finally, by determining the preset target range where the final parameter value falls, the garment material is identified based on the correspondence between the preset target range and the garment material. By changing the detection environment and utilizing the parameter differences under different environments, this electronic device can eliminate certain uncertainties affecting the detection results, thereby achieving a more accurate detection effect. This provides more precise data for subsequently selecting appropriate washing modes for different garment materials.

[0121] Example 4

[0122] like Figure 2 , 3 As shown, this embodiment provides a garment processing device. The garment processing device uses the material detection method in Embodiment 1, or includes the material detection device in Embodiment 2, or includes the electronic device in Embodiment 3.

[0123] This garment processing device is a washing machine. In both a first and second detection mode, the washing machine acquires first and second parameter values ​​via a light signal detector. A final parameter value is then derived from these first and second parameter values. In the second detection mode, the garment drum is illuminated by a different light color than in the first detection mode, causing the garments to be covered by a different light color. Different garment materials exhibit varying reflectivity to the light signal emitted by the light signal detector under different lighting conditions. This results in a difference between the second and first parameter values ​​acquired by the light signal detector. This difference is used to obtain the final parameter value. Finally, by determining the preset target range where the final parameter value falls, the garment material is identified based on the correspondence between the preset target range and the garment material. This electronic device, by altering the detection environment and utilizing the parameter differences under different conditions, can eliminate certain uncertainties affecting the detection results, thereby achieving more accurate detection. This provides more precise data for selecting appropriate washing modes for different garment materials.

[0124] In summary, the ingenious design of the material testing method lies in:

[0125] The method for detecting clothing material includes a first detection mode and a second detection mode. The difference between the second and first detection modes lies in the lighting color inside the garment processing drum, which differs from that in the first mode. This difference in lighting color results in the clothing being covered by a different light source. Different clothing materials exhibit varying reflectivity to the light emitted by the optical signal detection device under different lighting conditions. Consequently, the second parameter value obtained by the optical signal detection device differs from the first parameter value. This difference is used to obtain the final parameter value. Finally, by determining the preset target range where the final parameter value falls, the clothing material is identified based on the correspondence between the preset target range and the clothing material. Compared to simple image recognition or repeated parameter acquisition under the same environment, this material detection method, by changing the detection environment and utilizing the parameter differences under different environments, can eliminate certain uncertainties affecting the detection results, thus achieving a more accurate detection effect. This provides more precise data for selecting appropriate washing modes for different clothing materials.

[0126] It can be further understood that in this disclosure, "multiple" refers to two or more, and other quantifiers are similar. "And / or" describes the relationship between related objects, indicating that three relationships can exist; for example, A and / or B can represent: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. The singular forms "a," "the," and "the" are also intended to include the plural forms unless the context clearly indicates otherwise.

[0127] It is further understood that the terms "first," "second," etc., are used to describe various types of information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another, and do not indicate a specific order or degree of importance. In fact, the expressions "first," "second," etc., are completely interchangeable. For example, without departing from the scope of this disclosure, first information can also be referred to as second information, and similarly, second information can also be referred to as first information.

[0128] It is further understood that although operations are described in a specific order in the accompanying drawings in the embodiments of this disclosure, this should not be construed as requiring these operations to be performed in the specific order or serial order shown, or requiring all of the shown operations to be performed to obtain the desired result. In certain environments, multitasking and parallel processing may be advantageous.
