[0051] Among the technologies related to clothing material detection, camera sampling technology is generally used. Intelligent camera identification of clothing material is a technology that integrates image recognition technology, deep learning algorithm and expert system. Camera sampling technology relies on deep learning algorithm and expert system to judge clothing material, and the accuracy of clothing material detection is relatively low.

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

[0053] Embodiment 1:

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

[0055] A first detection mode and a second detection mode,

[0056] Acquire a first parameter value representing a material of the clothing, where the first parameter value is determined based on a light signal collected by the light signal detection component in a first detection mode;

[0057] Acquire a second parameter value representing the material of the clothing, where the second parameter value is determined based on the light signal collected by the light signal detection component in the second detection mode;

[0058] Obtaining a final parameter value representing a material of clothing, the final parameter value being determined by the first parameter value and the second parameter value, determining a preset target interval in which the final parameter value is located, and determining the material of clothing according to a correspondence between the preset target interval and the material of clothing;

[0059] In the second detection mode, the laundry processing tub has a light color different from that in the first detection mode.

[0060] In this embodiment, the detection method for clothing material is composed of a first detection mode and a second detection mode, wherein the difference between the second detection mode and the first detection mode is that, in the second detection mode, the clothing treatment drum has a light color different from that in the first detection mode, and both detection modes are related parameter values ​​obtained by light signals collected by the light signal detection element. Since, in the second detection mode, the clothing treatment drum has a light color different from that in the first detection mode, the clothing in the clothing treatment drum is covered with a light color different from that in the first detection mode, and different clothing materials have different reflection capabilities for the light signal emitted by the light signal detection element under different light color environments, so that there is a certain difference between the second parameter value and the first parameter value obtained by the light signal detection element, and the difference is used to obtain the final parameter value, and finally, by judging the preset target interval where the final parameter value is located, the clothing material is determined according to the corresponding relationship 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 changes the detection environment and uses the parameter differences under different environments to eliminate certain uncertain factors that affect the detection results, thereby achieving a more accurate detection effect. Provide more accurate data for subsequent selection of appropriate washing modes for clothes of different materials.

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

[0062] The first parameter value is a1, the second parameter value is a2, and the final parameter value is △ 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 component. The final parameter value is obtained by using this difference, 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 where 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 a single image recognition or a method of repeatedly obtaining parameters under the same environment, this material detection method can eliminate certain uncertain factors that affect 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, a1~f1, a total of 6 first parameter values, are obtained through the optical signal detection element. These 6 first parameter values ​​correspond to 6 types of clothing materials, among which a1~f1 can be data collected multiple times and processed by calculation. The multiple collections are parameter values ​​collected by the optical signal detection element at regular intervals. After each parameter value is collected by the optical signal detection element, the clothing processing drum is shaken out once, thereby ensuring the comprehensiveness of clothing material detection. In the second detection mode, a2~f2, a total of 6 second parameter values, are obtained through the optical signal detection element. These 6 second parameter values ​​correspond to the same 6 clothing materials detected in the first detection mode. The second parameter value is subtracted from the first parameter value of the corresponding material to obtain the final parameter value. If, in the first detection mode, there is an error between the preset target interval corresponding to the first parameter value obtained and the actual material, and in the second detection mode, there is no error between the preset target interval corresponding to the second parameter value obtained and the actual material, it will cause the two parameter values ​​to be unable to be subtracted and need to be re-detected. If, in the second detection mode, there is an error between the preset target interval corresponding to the second parameter value obtained and the actual material, and in the first detection mode, there is no error between the preset target interval corresponding to the first parameter value obtained and the actual material, it will cause As a result, the two parameter values ​​cannot be subtracted and need to be retested. Only when there is no error between the corresponding preset target intervals and the actual material in the first detection mode and the second detection mode, can the final parameter value be obtained, which further ensures the accuracy of the final parameter value, making the final detection result more accurate. Finally, 6 corresponding final parameter values ​​△a=|a2-a1|~△f=|f2-f1| are obtained, and the preset target intervals of the final parameter values ​​△a~△f are determined. The clothing material is determined according to the correspondence between the preset target intervals and the clothing material. The preset target intervals corresponding to △a~△c are all cotton, the preset target intervals corresponding to △d and △e are all linen, and the preset target intervals corresponding to △f are all silk. In this case, cotton materials account for 50%, linen materials account for 33%, and silk materials account for 17%. The optional washing mode is the cotton and linen washing mode.

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

[0067] The number of optical signal detection elements is n, n≥1, and the n optical signal detection elements are sequentially distributed along the circumference of the clothing processing drum in the clothing processing device, and each optical signal detection element includes an emitting electrode and a receiving electrode;

[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 to the clothes in the laundry processing drum, and controlling the receiver of any one of the optical signal detectors to receive the optical signal reflected by the clothes in the laundry processing drum.

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

[0070] Obtaining a first parameter value characterizing the material of clothing includes controlling the first emitter 201 and the second emitter 202 to transmit an optical signal to clothing in a clothing processing device, controlling the first receiving electrode 301 to receive an optical signal emitted by the first emitter 201 and reflected by clothing in a clothing processing drum, and controlling the second receiving electrode 302 to receive an optical signal emitted by the second emitter 202 and reflected by clothing in the clothing processing drum, wherein the optical signal emitted by the emitter will pass through the clothing in the clothing processing drum, wherein a portion of the optical signal is blocked and reflected by the clothing and received by the corresponding receiving electrode, a portion of the optical signal is absorbed by the clothing, and another portion of the optical signal penetrates the clothing, and clothing of different materials has different ability to reflect optical signals, thereby obtaining different first parameter values.

[0071] The method of obtaining the second parameter value characterizing the material of the clothing is the same as the method of obtaining the first parameter value characterizing the material of the clothing. The method of obtaining the first parameter value and the second parameter value characterizing the material of the clothing is simple, easy and highly accurate.

[0072] Optionally, in an implementation of this embodiment,

[0073] In the first detection mode, there is no light in the laundry treatment drum, and in the second detection mode, there is color light in the laundry treatment drum, or,

[0074] In the first detection mode, there is color light in the laundry processing drum, and in the second detection mode, there is no light in the laundry processing drum.

[0075] In the first detection mode, the laundry processing drum has colored lighting, and in the second detection mode, the laundry processing drum has a different lighting color from that in the first detection mode.

[0076] Preferably, in the first detection mode, there is no light in the laundry treatment drum, and in the second detection mode, there is red light in the laundry treatment drum. By installing a red light emitting source in the laundry treatment drum, the red light is irradiated on the clothes in the drum, thereby achieving red light covering the laundry treatment drum.

[0077] In the first detection mode, there is no light in the laundry treatment drum, and the first parameter value characterizing the material of the laundry is obtained through the optical signal detection component. In the second detection mode, there is red light in the laundry treatment drum, and the second parameter value characterizing the material of the laundry is obtained through the optical signal detection component. In the red light environment, the laundry has different reflection capabilities to the light signal emitted by the optical signal detection component, so there is a certain difference between the second parameter value and the first parameter value obtained by the optical signal detection component. The final parameter value is obtained by using this difference, and finally the preset target interval where the final parameter value is located is determined according to the corresponding relationship between the preset target interval and the material of the laundry. Compared with single image recognition or repeated parameter acquisition under the same environment, this material detection method can eliminate certain uncertain factors that affect the detection results by changing the detection environment and using the parameter differences under different environments, thereby achieving a more accurate detection effect. More accurate data is provided for the subsequent selection of appropriate washing modes for clothes of different materials.

[0078] It should be noted that, in an 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.

[0079] 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.

[0080] In an embodiment, the preset calculation formula for calculating the diffuse reflection parameter value may 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 (light intensity related).

[0081] In the embodiment, in order to determine the material of the 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.

[0082] 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.

[0083] The corresponding relationship 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 diffuse reflection standard value interval P1, which is the corresponding relationship. When the diffuse reflection parameter value is within P1, it can be determined that the clothing material of the clothing is a.

[0084] Optionally, in an implementation of this embodiment,

[0085] In the first detection mode,

[0086] Controlling the optical signal detection element to repeatedly acquire multiple optical signals, each of the optical signals corresponds to a first sub-parameter value, and multiple first sub-parameter values ​​form a first parameter value group;

[0087] Controlling the optical signal detection component to obtain a plurality of the first parameter value groups, and calculating the first parameter value according to the plurality of the first parameter value groups;

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

[0089] Controlling the optical signal detection element to repeatedly acquire multiple optical signals, 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 component is controlled to obtain a plurality of second parameter value groups, and the second parameter value is calculated according to the plurality of second parameter value groups.

[0091] Further, the calculating the first parameter value according to the plurality of first parameter value groups includes:

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

[0093] Selecting a median of average values ​​of a plurality of first parameter value groups as the first parameter value;

[0094] The calculating the second parameter value according to the plurality of second parameter value groups comprises:

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

[0096] The median of the average values ​​of a plurality of the second parameter value groups is selected as the second parameter value.

[0097] In this embodiment, the first parameter value and / or the second parameter value is data after the above-mentioned operation processing. The method of taking the mean after grouping and taking the median can further detect the accuracy of the data and improve the accuracy of clothing material detection.

[0098] Embodiment 2

[0099] like Figure 2 As shown, this embodiment provides a material detection device, which is arranged in a clothes processing drum of a clothes processing device, including:

[0100] n optical signal detection elements, each optical signal detection element comprises an emitting electrode and a receiving electrode, n≥2;

[0101] A lamp body, which is used to irradiate colored light into the laundry treatment tub;

[0102] The n optical signal detectors are configured such that an emitter of any of the n optical signal detectors emits an optical signal to the clothes in the clothes processing tub, and a receiver of any of the optical signal detectors receives an optical signal reflected by the clothes in the clothes processing tub.

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

[0104] To obtain a first parameter value characterizing the material of the clothing, an optical signal is emitted to the clothing in the clothing processing device through the first emitter 201 and the second emitter 202, and the first receiving electrode 301 is controlled to receive the optical signal emitted by the first emitter 201 reflected by the clothing in the clothing processing drum, and the second receiving electrode 302 is controlled to receive the optical signal emitted by the second emitter 202 reflected by the clothing in the clothing processing drum. The optical signal emitted by the emitter will pass through the clothing in the clothing processing drum, wherein a part of the optical signal is blocked and reflected by the clothing and received by the corresponding receiving electrode, a part of the optical signal is absorbed by the clothing, and another part of the optical signal penetrates the clothing. Clothes of different materials have different reflection capabilities for optical signals, thereby obtaining different first parameter values.

[0105] The method of obtaining the second parameter value characterizing the material of the clothing is the same as the method of obtaining the first parameter value characterizing the material of the clothing. The method of obtaining the first parameter value and the second parameter value characterizing the material of the clothing is simple and easy. It not only has high accuracy, but also the structure of the optical signal detection element is relatively simple, and is suitable for use in a clothing processing drum.

[0106] The lamp body works to irradiate colored light into the laundry treatment drum, and the colored light irradiates the laundry in the drum, so that the laundry treatment drum is covered by the colored light.

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

[0108] The material detection device also includes: n lifting ribs 1 , the n lifting ribs 1 correspond one to one to the n optical signal detection components, and the emitter and the receiver in the same optical signal detection component are arranged flat on the corresponding lifting ribs 1 .

[0109] In this embodiment, n=2. In this embodiment, the optical signal detection element uses the lifting rib 1 as a carrier to give full play to the detection effect. The two sides of the lifting rib 1 are in an open state. During the operation of the optical signal detection element, the two sides of the lifting rib 1 provide effective passage space for the emission and reception of the optical signal to avoid the light signal from being blocked, so that the optical signal detection element is in a better working state and has a more accurate detection result. The optical signal detection element is combined with the lifting rib, the structure is relatively simple and improves the effectiveness and accuracy of clothing material detection.

[0110] Optionally, in an implementation of this embodiment,

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

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

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

[0117] This embodiment provides an electronic device, the electronic device comprising:

[0118] Memory, which stores computer instructions;

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

[0120] The electronic device obtains the first parameter value and the second parameter value through the first detection mode and the second detection mode, and then obtains the final parameter value from the first parameter value and the second parameter value. In the second detection mode, the clothing treatment drum has a different light color from that in the first detection mode, so that the clothing in the clothing treatment drum is covered with a light color different from that in the first detection mode, and different clothing materials have different reflection capabilities for the light signal emitted by the light signal detection component under different light color environments, so there is a certain difference between the second parameter value and the first parameter value obtained by the light signal detection component, and the final parameter value is obtained by using the difference, and finally the preset target interval where the final parameter value is located is determined according to the corresponding relationship between the preset target interval and the clothing material. The electronic device can eliminate certain uncertain factors that affect the detection results by changing the detection environment and using the parameter differences under different environments, thereby achieving a more accurate detection effect.

[0121] Embodiment 4

[0122] like Figure 2 , 3 As shown, this embodiment provides a clothing processing device, which uses the material detection method in the first embodiment, or includes the material detection device in the second embodiment, or includes the electronic device in the third embodiment.

[0123] The clothing processing device is a washing machine. In the first detection mode and the second detection mode, the washing machine obtains the first parameter value and the second parameter value through the optical signal detection element, and then obtains the final parameter value from the first parameter value and the second parameter value. In the second detection mode, the clothing processing drum has a light color different from that in the first detection mode, so that the clothing in the clothing processing drum is covered with a light color different from that in the first detection mode, and different clothing materials have different reflection capabilities for the light signal emitted by the optical signal detection element in the environment of different light colors, so there is a certain difference between the second parameter value and the first parameter value obtained by the optical signal detection element. The final parameter value is obtained by using the difference, and finally the preset target interval where the final parameter value is located is determined according to the corresponding relationship between the preset target interval and the clothing material. The electronic device can eliminate certain uncertain factors that affect the detection result by changing the detection environment and using the parameter difference under different environments, thereby achieving a more accurate detection effect. More accurate data is provided for the subsequent selection of appropriate washing modes for clothing of different materials.

[0124] In summary, the ingenious idea of ​​the material detection method is:

[0125] The detection method of clothing material includes a first detection mode and a second detection mode. The difference between the second detection mode and the first detection mode is that in the second detection mode, the clothing treatment drum has a different light color from that in the first detection mode. Since the clothing treatment drum has a different light color from that in the first detection mode in the second detection mode, the clothing in the clothing treatment drum is covered with a light color different from that in the first detection mode. Different clothing materials have different reflection capabilities for the light signal emitted by the light signal detection component 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 component. The final parameter value is obtained by using the difference. Finally, the preset target interval where the final parameter value is located is judged, and the clothing material is determined according to the corresponding relationship between the preset target interval and the clothing material. Compared with a single image recognition or a method of repeatedly obtaining parameters under the same environment, the material detection method changes the detection environment and uses the parameter differences under different environments to eliminate certain uncertain factors that affect the detection results, thereby achieving a more accurate detection effect. More accurate data is provided for the subsequent selection of appropriate washing modes for clothing of different materials.
