Description

Technical Field

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

[0002] Before processing clothes, the clothes processing equipment will identify the material of the clothes, so as to select appropriate operating parameters according to the material of the clothes and improve the processing effect of the clothes. When identifying the material of clothes, a camera is installed inside the clothes processing equipment, and the image of the clothes is captured by the camera, and then the material of the clothes is identified by image processing technology.

[0003] However, this method is prone to inaccurate camera focus or lens being blocked by clothing, resulting in failure to obtain clear clothing images or failure to capture images of all clothing, resulting in inaccurate clothing material recognition. Summary of the invention

[0004] The present application provides a clothing material identification method and clothing processing equipment to at least solve the technical problem of inaccurate clothing material identification.

[0005] According to a first aspect of an embodiment of the present application, a method for identifying clothing material is provided, which is applied to a clothing processing device, wherein the clothing processing device includes a processing drum, and a plurality of groups of light detection elements are arranged on the processing drum, wherein the light detection element includes an emitter and a receiver, wherein the emitter is used to emit a light signal to the receiver, and the receiver is used to receive the light signal that can be transmitted with a load and generate corresponding light parameters, wherein the method includes:

[0006] In response to the identification signal of the clothing material, controlling at least one of the light detection elements to operate;

[0007] Based on the operation of the optical detection element, a first optical parameter of the optical signal emitted by the emitter and a second optical parameter collected by the receiver are obtained;

[0008] Calculate the optical parameter change value according to the first optical parameter and the second optical parameter corresponding to the running optical detection element, wherein the first optical parameter is the optical parameter of the optical signal emitted by the emitter of the optical detection element;

[0009] According to the matching relationship between each of the light parameter change values ​​and the preset material threshold, an identification result representing the material of the clothing is generated, wherein different materials correspond to different material thresholds.

[0010] Through the above content, the light detection element is used to realize the identification of clothing materials. Since the light detection element only needs to emit a light signal, it is not easy to fail to accurately identify the clothing material, thereby improving the reliability and accuracy of clothing material identification. At the same time, based on the calculation of the first light parameter when the light signal is emitted and the second light parameter after the load is transmitted, the identification result is obtained. Since clothes of different materials consume different light signals, the identification result can accurately reflect the material of the clothes loaded in the processing drum, thereby improving the accuracy of clothing material identification.

[0014] Through the above content, the light intensity is used to realize the calculation of the light parameter change value. Since different clothes have different effects on the light signal intensity, the light parameter change value obtained by using light intensity is easier to distinguish the clothing material, which helps to improve the accuracy of clothing material recognition.

On the other hand, multiple detections help to improve the comprehensiveness of the detection, help to reduce the misjudgment rate, and improve the accuracy of clothing material identification.

[0021] Optionally, generating an identification result representing the material of clothing according to a matching relationship between each of the light parameter change values ​​and a preset material threshold value includes:

[0022] Calculate the average value of multiple optical parameter change values ​​corresponding to each running optical detection element;

[0023] The average value is compared with the material threshold. If the average value is the same as the material threshold or is within the threshold interval of the material threshold, a match is confirmed, and the identification result of the clothing material associated with the matched material threshold is generated.

[0024] Through the above content, the recognition result is obtained by calculating the average value, which is beneficial to improve the accuracy of clothing material recognition and reduce the occupation of computing resources.

[0025] Optionally, the method further comprises:

[0026] The number of the optical detection components that need to be operated is determined according to the load, wherein the greater the load, the greater the number of the optical detection components that need to be operated.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0046] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0047] According to an embodiment of the present application, an embodiment of a clothing material identification method and a clothing processing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0048] Before processing clothes, the clothes processing equipment will identify the material of the clothes, so as to select appropriate operating parameters according to the material of the clothes and improve the processing effect of the clothes. When identifying the material of clothes, a camera is installed inside the clothes processing equipment, and the image of the clothes is captured by the camera, and then the material of the clothes is identified by image processing technology.

[0049] However, this method is prone to inaccurate camera focus or lens being blocked by clothing, resulting in failure to obtain clear clothing images or failure to capture images of all clothing, resulting in inaccurate clothing material recognition.

[0050] Based on this, this embodiment provides a clothing material identification method, which is applied to a clothing processing device, wherein the clothing processing device includes a processing drum 1, and a plurality of light detection components are arranged on the processing drum 1, and the light detection components include an emitter 2 and a receiver 3, and the emitter 2 is used to emit a light signal to the receiver 3, and the receiver 3 is used to receive the light signal that can be transmitted with the load 4 and generate corresponding light parameters, such as Figure 1 As shown, the clothing material recognition method includes:

[0051] S100, in response to an identification signal of clothing material, controlling at least one of the light detection elements to operate.

[0052] Among them, the identification signal refers to a signal generated when the material type of the clothing needs to be identified. In this embodiment, the identification signal can be a specific signal used to trigger the operation of this method, or it can be a code sentence that can play this role. This embodiment does not specifically limit the structure and content of the identification signal.

[0053] Controlling the operation of the optical detection element refers to controlling the emitter of the optical detection element to emit a light signal to a matching receiver. If there is a load in the processing tube, the light signal will pass through the load and be received by the receiver. Specifically, the receiver and emitter of the same optical detection element are two electrodes that match each other.

[0054] S102: Based on the operation of the optical detection element, obtain a first optical parameter of the optical signal emitted by the emitter and a second optical parameter collected by the receiver.

[0055] In one embodiment, if the optical signal passes through the load, the parameters such as the wavelength or frequency of the optical signal will be affected. Clothes of different materials have different degrees of influence on the optical signal. Based on this, the material of the clothing can be determined according to the difference between the first optical parameter and the second optical parameter. Specifically, the types of the first optical parameter and the second optical parameter should be the same. For example, if the first optical parameter is the wavelength, the second optical parameter is also the wavelength. If the first optical parameter is the frequency, the second optical parameter is also the frequency. In addition, the first optical parameter can also be a parameter calculated using parameters such as the wavelength and / or frequency of the optical signal. This embodiment does not limit the specific calculation process.

[0056] S104: Calculate a light parameter change value according to the first light parameter and the second light parameter corresponding to the operating light detection component.

[0057] The first optical parameter is an optical parameter of an optical signal emitted by an emitter of the optical detection element, and the optical parameter change value refers to a change amount of the second optical parameter compared to the corresponding first optical parameter.

[0058] S106: Generate an identification result representing the material of the clothing according to the matching relationship between each of the light parameter change values ​​and the preset material threshold.

[0059] Among them, different materials correspond to different material thresholds.

[0060] Since different materials have different material thresholds, the recognition result can be obtained based on the matching relationship between the light parameter change value and each material threshold. Specifically, when the light parameter change value is the same as a certain material threshold, the two are considered to match, or when the light parameter change value exceeds a certain material threshold, the two are considered to match.

[0061] Through the above content, the light detection element is used to realize the identification of clothing materials. Since the light detection element only needs to emit a light signal, it is not easy to fail to accurately identify the clothing material, thereby improving the reliability and accuracy of clothing material identification. At the same time, based on the calculation of the first light parameter when the light signal is emitted and the second light parameter after being transmitted by the load 4, the identification result is obtained. Since clothes of different materials consume different light signals, the identification result can accurately reflect the material of the clothes in the load 4 in the processing drum 1, thereby improving the accuracy of clothing material identification.

[0062] Optionally, the calculating the light parameter change value according to the first light parameter and the second light parameter corresponding to the running light detection element includes:

[0063] The difference between the first light parameter and the second light parameter corresponding to each operating light detection element is calculated to obtain the light parameter change value of each operating light detection element.

[0064] Through the above content, the light parameter change value can be obtained by calculating the difference, and the calculation process is simple, which is conducive to reducing the occupation of computing resources, reducing the cost of clothing material recognition, and improving the efficiency of clothing material recognition.

[0065] Optionally, the first light parameter includes a first light intensity, and the second parameter includes a second light intensity;

[0066] The calculating the difference between the first light parameter and the second light parameter corresponding to each running light detection element to obtain the light parameter change value of each running light detection element includes:

[0067] The difference between the first light intensity and the second light intensity corresponding to each operating light detection element is calculated to obtain the light parameter change value of each operating light detection element.

[0068] Through the above content, the light intensity is used to realize the calculation of the light parameter change value. Since different clothes have different effects on the light signal intensity, the light parameter change value obtained by using light intensity is easier to distinguish the clothing material, which helps to improve the accuracy of clothing material recognition.

[0069] Optionally, obtaining the second light parameter collected by the receiving electrode based on the operation of the light detecting element includes:

[0070] When the processing cylinder is in a stationary state, the light detection element is controlled to send out light signals multiple times to obtain multiple second light parameters, and / or,

[0071] Controlling the processing tube to be in a stationary state after rotating at least once, controlling the light detecting element to emit light signals multiple times, and obtaining multiple second light parameters, wherein the processing tube has a set maximum number of rotations;

[0072] The calculating the light parameter change value according to the first light parameter and the second light parameter corresponding to the running light detection element includes:

[0073] A plurality of light parameter change values ​​are obtained by calculation according to the first light parameter and a plurality of the second light parameters corresponding to the operating light detection element.

[0074] That is to say, the processing cylinder will be controlled to rotate for multiple times, and multiple tests will be performed after each rotation to obtain multiple second-level parameters.

[0075] Through the above content, when the light detection component is controlled to identify the material of clothing, the light detection component will be controlled to emit multiple light signals to obtain multiple second light parameters. The processing drum can also be rotated to repeat the detection action of the light detection component to obtain multiple light parameter change values. On the one hand, the rotation of the processing drum can change the position and state of the internal load, making the second light parameter more accurate. On the other hand, multiple detections help to improve the comprehensiveness of the detection, help to reduce the misjudgment rate, and improve the accuracy of clothing material identification.

[0076] Optionally, generating an identification result representing the material of clothing according to a matching relationship between each of the light parameter change values ​​and a preset material threshold value includes:

[0077] Calculate the average value of multiple optical parameter change values ​​corresponding to each running optical detection element;

[0078] The average value is compared with the material threshold. If the average value is the same as the material threshold or is within the threshold interval of the material threshold, a match is confirmed, and the identification result of the clothing material associated with the matched material threshold is generated.

[0079] In one embodiment, when there is only one material load and multiple light detection components are in operation, the average value of each light detection component is calculated respectively, and then the average values ​​corresponding to the multiple light detection components are averaged to obtain an average value for comparison with the material threshold. The corresponding recognition result can be generated based on the comparison between the average value and the material threshold.

[0080] In another embodiment, when there are loads of various materials and multiple light detection elements are in operation, the average values ​​of each light detection element are calculated respectively, and then the average value corresponding to each light detection element is compared with the material threshold to obtain the recognition results detected by each light detection element.

[0081] Through the above content, the recognition result is obtained by calculating the average value, which is beneficial to improve the accuracy of clothing material recognition and reduce the occupation of computing resources.

[0082] Optionally, the method further comprises:

[0083] The number of the optical detection components that need to be operated is determined according to the load, wherein the greater the load, the greater the number of the optical detection components that need to be operated.

[0084] According to the above content, when the load is large, the number of light detection elements in operation is also large, which is easy to ensure the accuracy of clothing material recognition. When the load is small, the number of light detection elements in operation is also small, which is easy to save energy.

[0085] Optionally, determining the number of the optical detection elements that need to be operated according to the load includes:

[0086] Obtaining the full load weight of the laundry processing device and the load weight of the load 4, wherein the load amount includes the load weight;

[0087] Compare the load weight with the full load weight to obtain the load amount;

[0088] The number of the optical detection components that need to be operated is determined according to the load interval to which the load belongs, wherein the larger the load interval, the larger the number of the optical detection components that need to be operated.

[0089] Through the above content, the load weight is easy to obtain with high accuracy, and it is easy to improve the accuracy of determining the number of light detection parts.

[0090] Optionally, controlling at least one of the light detection components to operate includes:

[0091] If a plurality of the light detecting elements are operated, the emitters 2 of the plurality of light detecting elements are controlled to emit light signals one by one.

[0092] Through the above content, multiple emitters 2 emit light signals one by one, avoiding interference between light signals emitted by different emitters 2, which is beneficial to improving the accuracy of clothing material recognition.

[0093] This embodiment also provides a clothes processing device, such as Figure 2As shown, it includes a processing tube 1, on which a plurality of light detection elements are arranged, and the light detection elements include an emitter 2 and a receiver 3, wherein the emitter 2 is used to emit a light signal to the receiver 3, and the receiver 3 is used to receive the light signal that can be transmitted with the load 4 and generate corresponding light parameters;

[0094] The clothing processing device uses the above-mentioned clothing material identification method to identify the material of the clothing.

[0095] Optionally, one of the emitter 2 and the receiver 3 of the light detection element is arranged at the barrel mouth of the processing barrel 1 and multiple emitters 2 are distributed along the circumference of the barrel mouth, and the other of the emitter 2 and the receiver 3 of the light detection element is arranged at the barrel wall or the barrel bottom of the processing barrel 1. The emitter 2 and the receiver 3 of the light detection element are staggered so that when the emitter 2 transmits a light signal to the associated receiver 3, the propagation path of the light signal is an inclined route relative to the barrel wall of the processing barrel.

[0096] Optionally, the emitter 2 and / or the receiver 3 are arranged in a protective shell that allows optical signals to pass through.

[0097] The protective shell protects the emitter 2 and / or the receiver 3 to prevent the water in the treatment barrel 1 from contacting the emitter 2 and / or the receiver 3. Specifically, the protective shell is a transparent shell.

[0098] Optionally, the laundry processing device includes a pulsator washing machine.

[0099] In addition, for ease of understanding, the identification of materials based on the transmission of light signals is explained as follows: transmission may occur after the light signal comes into contact with clothing, wherein when transmission occurs after the light signal comes into contact with clothing, a transmission parameter value (equivalent to the second light parameter in this embodiment) may be obtained.

[0100] Specifically, the transmission parameter value may be a parameter value of the transmission light signal itself after transmission occurs, such as the transmittance, light intensity, etc. of the transmission light signal, or may be a parameter value obtained after calculating the parameter value of the transmission light signal itself, such as substituting the transmittance and / or light intensity of the transmission light signal into a preset calculation formula to obtain the transmission parameter value. In general, as long as different clothing materials can correspond to different transmission parameter values.

[0101] In one embodiment, the preset calculation formula for calculating the transmission parameter value may be a formula including the wavelength and light intensity of the transmitted light signal, for example, the transmission parameter value b=T%*φluminous flux*power factor (related to light intensity), and the transmittance T%=I(light intensity after transmission attenuation) / IO(original light intensity)*100%.

[0102] In one embodiment, in order to determine the material of the clothing, a transmission standard value interval is preset (corresponding to the material threshold of this embodiment), and different transmission standard value intervals correspond to different clothing materials. In other words, there is a corresponding relationship between the transmission standard value intervals and the clothing materials.

[0103] Specifically, the transmission standard value interval is a numerical interval composed of transmission standard values. It should be noted that the transmission standard value and the transmission parameter value are of the same type or are obtained using the same algorithm. The difference is that the transmission standard value is a parameter value obtained by performing a transmission experiment on the clothing when the clothing material is known, while the transmission parameter value is a parameter value obtained by transmitting the clothing when the clothing material is actually identified. For ease of understanding, for example, during the test, the transmittance and light intensity of the transmitted light signal are calculated using formula B to obtain the transmission standard value. After multiple tests on clothing of material b, a numerical interval Q1 can be divided according to all the obtained transmission standard values. When the clothing material is actually identified, the transmittance and light intensity of the transmitted light signal are also calculated using formula B to obtain the transmission parameter value. Since the calculation process of the transmission parameter value is the same as that of the transmission standard value, the clothing material of the clothing can be determined according to the transmission parameter value.

[0104] The corresponding relationship between the transmission standard value interval and the clothing material is: each type of clothing material corresponds to a transmission standard value interval, and different types of clothing materials correspond to different transmission standard value intervals. For example, material a corresponds to the transmission standard value interval Q1, which is the corresponding relationship. When the transmission parameter value is within Q1, it can be determined that the clothing material of the clothing is a. Preferably, the corresponding relationship obtained by testing with an ultraviolet sensor includes: the material tested at 10-13 is cotton, the material tested at 13.5-15.5 is linen, the material corresponding to 19-23 is wool, the material corresponding to 16.5-18.9 is silk, the material corresponding to 29-33 is polyester fiber, and the material corresponding to 33.5-39 is chemical fiber.

[0105] For ease of understanding, in an application scenario, the use process of the clothing material recognition method and clothing processing device of this embodiment is as follows:

[0106] Parameter Description:

[0107] The light intensity λ1 emitted by emitter 2

[0108] The light intensity λ2 received by the receiving electrode 3

[0109] The preset values ​​of the light intensity difference of each material after transmission are: cotton: 70, linen: 60, silk: 30, polyester: 40, wool: 80, chemical fiber: 50

[0110] Structure Description:

[0111] Control logic description:

[0112] The drum mouth is equipped with multiple emitters 2 of ultraviolet sensors. The initial light intensity of the emitted ultraviolet light is λ1, and the wavelength range used is 100-400nm. Each ultraviolet light works in sequence and cannot work at the same time. Working at the same time will affect the light intensity λ2 received by the receiving electrode 3 after attenuation through the transmitted clothes. Each emitter 2 works in sequence, and the receiving electrode 3 facing each other in the empty drum state receives the ultraviolet light emitted by the facing emitter 2. The user puts the laundry into the drum, and the motor at the bottom of the vertical drum of the pulsator starts to weigh the clothes in the drum to determine whether there are clothes and whether the weight of the clothes is half loaded, less than half loaded, or more than half loaded.

[0113] If it is less than half load, the emitters 24 emitters 2 of the UV sensor around the drum mouth will work, and each emitter 2 is spaced 90° apart to form a circle around the drum mouth to ensure that the detection coverage covers the entire drum. After the emitter 2 emits the light intensity λ1, it passes through the clothes, and the receiver 3 receives the light intensity λ2 of the transmitted UV light, calculates the light intensity difference △λ, feeds the light intensity difference back to the MCU chip of the main control board, and stores the data in the ROM memory inside the chip to achieve the storage function, so that the data can be called later to calculate the average value. During the detection, the drum cannot rotate, and each detection is 10s, and a measured value is taken every 1s. After 10 detections, the 10 light intensity differences △λ are converted through the algorithm logic of the mainboard to obtain the average value a, and then compared with the preset values ​​of each material to determine what kind of clothes are inside the drum.

[0114] If the clothes in the drum are half loaded, the drum mouth uses 8 ultraviolet rays to detect the clothes in the drum, and each adjacent emitter 2 is 45° apart, forming a circle of the drum mouth to ensure coverage of the detection area. If the motor detects that the weight of the clothes in the drum is fully loaded with 10kg, the emitter 2 at the drum mouth has 12 emitters 2 working, and the corresponding receiving electrodes 3 on the side wall of the inner drum also have 12 receiving electrodes 3 for receiving.

[0115] For example, when clothes are tested in the ultraviolet wavelength band of 100-400nm, the light intensity emitted by the emitter 2 is λ1. After the motor detects that the weight of the clothes is half-loaded, if the drum is fully loaded with 10kg, then half-load is 5kg. The light intensity received by the receiver 3 after the clothes are transmitted through the ultraviolet rays is λ2. At this time, λ2 is fed back to the main board for storage. After 10 consecutive collections, the main board calculates the light intensity difference △λ between the emitter 2 and the receiver 3 through the algorithm = λ1-λ2. At this time, the average value △λ of the 10 light intensity differences detected for the first time is 100. After the first detection is completed, the motor at the bottom of the drum rotates to drive the drum to rotate, stir the clothes, and start the second detection. The light intensity difference △λ is also calculated, and the average value is 70. After the second detection is completed, the clothes inside the drum are rotated again, and the average value of the light intensity difference △λ detected after the third transmission is obtained, and the average value is 130. In summary, the material of the clothes detected three times can be determined as cotton, and the material of the other kind of clothes is silk. The silk mode can be run based on the detected material. The running mode must give priority to the mode for materials that need more protection. After half of the washing time, AI smart washing can be used to wash the clothes more cleanly.
