Description

Technical Field

[0001] This application relates to the field of clothing recognition, and more specifically, to a method for identifying clothing materials and a clothing processing device. Background Technology

[0002] Before processing clothing, garment processing equipment identifies the fabric material to select appropriate operating parameters and improve processing efficiency. Currently, fabric material identification involves installing a camera inside the garment processing equipment to capture images of the clothing, which are then processed using image processing technology to determine the fabric material.

[0003] However, this method is prone to errors due to inaccurate camera focusing or the lens being blocked by clothing, resulting in unclear images of clothing or inability to capture images of all clothing, leading to inaccurate identification of clothing materials. Summary of the Invention

[0004] This application provides a method for identifying clothing materials and a clothing processing device to at least solve the technical problem of inaccurate clothing material identification.

[0005] According to a first aspect of the embodiments of this application, a method for identifying clothing material is provided, applied to a clothing processing device. The clothing processing device includes a processing cylinder, on which multiple sets of optical detection elements are disposed. Each optical detection element includes an emitter and a receiver. The emitter is used to emit an optical signal to the receiver, and the receiver is used to receive the optical signal that can be transmitted through a load and generate corresponding optical parameters. The method includes:

[0006] In response to a signal indicating the material of the clothing, at least one of the optical detection devices is controlled to operate;

[0007] Based on the operation of the optical detection device, the first optical parameters of the optical signal emitted by the emitter and the second optical parameters collected by the receiver are obtained.

[0008] The optical parameter change value is calculated based on the first optical parameter and the second optical parameter corresponding to the operating optical detection device, wherein the first optical parameter is the optical parameter of the optical signal emitted by the emitter of the optical detection device;

[0009] Based on the matching relationship between the changes in each of the light parameters and the preset material threshold, a recognition result characterizing the material of the clothing is generated, wherein different materials correspond to different material thresholds.

[0010] The above describes how optical detection devices are used to identify clothing materials. Since these devices only need to emit light signals, inaccurate identification of clothing materials is less likely, thus improving the reliability and accuracy of material identification. Furthermore, the identification result is obtained by calculating the first light parameter at the time of light emission and the second light parameter after transmission through the load. Because different clothing materials consume light signals differently, the identification result accurately reflects the clothing material loaded in the processing drum, further enhancing the accuracy of material identification.

[0011] Optionally, the first optical parameter includes a first optical intensity, and the second parameter includes a second optical intensity;

[0012] The step of calculating the optical parameter change value based on the first and second optical parameters corresponding to the operating optical detection device includes:

[0013] The difference between the first light intensity and the second light intensity corresponding to each operating photodetector is calculated to obtain the change value of the optical parameters of each operating photodetector.

[0014] Based on the above, the calculation of light parameter changes is achieved using light intensity. Since different types of clothing have different effects on the light signal intensity, the light parameter changes obtained using light intensity are more likely to distinguish clothing materials, which helps to improve the accuracy of clothing material identification.

[0015] Optionally, obtaining the second optical parameters collected by the receiving electrode based on the operation of the photodetector includes:

[0016] When the processing cylinder is stationary, the controlled photodetector emits light signals multiple times to obtain multiple second light parameters, and / or,

[0017] The processing cylinder is controlled to rotate at least once and then remain stationary. The photodetector is controlled to emit light signals multiple times to obtain multiple second light parameters. The processing cylinder has a set maximum number of rotations.

[0018] The step of calculating the optical parameter change value based on the first and second optical parameters corresponding to the operating optical detection device includes:

[0019] Multiple optical parameter variation values ​​are calculated based on the first optical parameter and multiple second optical parameters corresponding to the operating optical detection device.

[0020] Based on the above, when the optical detector is controlling the operation to identify the material of clothing, it will emit light signals multiple times to obtain multiple second optical parameters. The processing cylinder can also be rotated to repeat the detection action of the optical detector, which can obtain multiple changes in optical parameters. On the one hand, the rotation of the processing cylinder can change the position and state of the internal load, making the second optical parameters more accurate. On the other hand, multiple detections help to improve the comprehensiveness of detection, reduce the false judgment rate, and improve the accuracy of clothing material identification.

[0021] Optionally, generating a recognition result characterizing the clothing material based on the matching relationship between the various light parameter changes and preset material thresholds includes:

[0022] Calculate the average value of the changes in multiple optical parameters corresponding to each operating optical detection device;

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

[0024] The above methods, which calculate the average value to obtain the recognition result, help improve the accuracy of clothing material recognition and reduce the consumption of computing resources.

[0025] Optionally, the method further includes:

[0026] The number of optical detectors that need to be operated is determined based on the load, wherein the larger the load, the larger the number of optical detectors that need to be operated.

[0027] Based on the above, under high load conditions, a larger number of optical detection devices operate, making it easier to ensure the accuracy of clothing material identification. Under low load conditions, a smaller number of optical detection devices operate, making it easier to save energy.

[0028] Optionally, determining the number of optical detectors that need to be operated based on the load includes:

[0029] Obtain the full-load weight of the garment processing equipment and the load weight of the load;

[0030] The load amount is obtained by comparing the load weight with the full load weight;

[0031] The number of optical detectors that need to be operated is determined based on the load range to which the load belongs, wherein the larger the load range, the larger the number of optical detectors that need to be operated.

[0032] Based on the above, the load weight is easy to obtain and has high accuracy, which makes it easy to improve the accuracy of determining the number of optical detection elements.

[0033] Optionally, controlling the operation of at least one of the photodetectors includes:

[0034] If multiple photodetectors are operated, the emitters of the multiple photodetectors are controlled to emit light signals one by one.

[0035] Through the above methods, multiple emitters emit light signals one by one, avoiding interference between light signals emitted by different emitters, which helps to improve the accuracy of clothing material identification.

[0036] According to a second aspect of the present application, a garment processing device is provided, including a processing cylinder. The processing cylinder is provided with a plurality of optical detection elements. Each optical detection element includes an emitter and a receiver. The emitter is used to emit an optical signal to the receiver, and the receiver is used to receive the optical signal that can be transmitted through a load and generate corresponding optical parameters.

[0037] The garment processing equipment uses the garment material identification method described above to identify the material of the garment.

[0038] Optionally, one of the emitter and receiver of the photodetector is disposed at the opening of the processing cylinder and multiple emitters are distributed around the circumference of the opening. The other emitter and receiver of the photodetector is disposed on the cylinder wall or bottom of the processing cylinder. The emitter and receiver of the photodetector are staggered so that when the emitter emits a light signal to the associated receiver, the propagation path of the light signal is an inclined path relative to the cylinder wall of the processing cylinder.

[0039] Optionally, the emitter and / or receiver are disposed within a protective housing that allows optical signals to pass through.

[0040] Optionally, the garment processing equipment includes a top-loading washing machine.

[0041] The technical effects achieved by the second aspect are similar to those achieved by the corresponding technical means in the first aspect, and will not be repeated here. Attached Figure Description

[0045] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort 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, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0047] According to the embodiments of this 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 in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Also, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0048] Before processing clothing, garment processing equipment identifies the fabric material to select appropriate operating parameters and improve processing efficiency. Currently, fabric material identification involves installing a camera inside the garment processing equipment to capture images of the clothing, which are then processed using image processing technology to determine the fabric material.

[0049] However, this method is prone to errors due to inaccurate camera focusing or the lens being blocked by clothing, resulting in unclear images of clothing or inability to capture images of all clothing, leading to inaccurate identification of clothing materials.

[0050] Based on this, this embodiment provides a method for identifying clothing material, applied to a clothing processing device. The clothing processing device includes a processing cylinder 1, on which multiple sets of photodetectors are disposed. Each photodetector includes an emitter 2 and a receiver 3. The emitter 2 emits a light signal to the receiver 3, and the receiver 3 receives the light signal that can be transmitted through a load 4 and generates corresponding light parameters, such as... Figure 1 As shown, clothing material identification methods include:

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

[0052] The identification signal refers to the signal generated when it is necessary to identify the material type of clothing. 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] Specifically, controlling the operation of the photodetector refers to controlling the emitter of the photodetector to emit a light signal to a matched receiver. If there is a load inside the processing cylinder, the light signal will pass through the load and be received by the receiver. In particular, the receiver and emitter of the same photodetector are two matched electrodes.

[0054] S102. Based on the operation of the optical detection device, the first optical parameters of the optical signal emitted by the emitter and the second optical parameters collected by the receiver are obtained.

[0055] In one embodiment, if an optical signal passes through a load, parameters such as the wavelength or frequency of the optical signal will be affected. Different clothing materials have varying degrees of influence on the optical signal; therefore, the material of the clothing can be determined based on the difference between the first and second optical parameters. Specifically, the first and second optical parameters should be of the same type. For example, if the first optical parameter is wavelength, the second optical parameter is also wavelength; if the first optical parameter is frequency, then the second optical parameter is also frequency. Furthermore, 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 the change value of the optical parameters based on the first and second optical parameters corresponding to the operating optical detection device.

[0057] Wherein, the first optical parameter is the optical parameter of the optical signal emitted by the emitter of the optical detector, and the optical parameter change value refers to the change of the second optical parameter relative to the corresponding first optical parameter.

[0058] S106. Based on the matching relationship between the change values ​​of each of the light parameters and the preset material threshold, generate an identification result characterizing the material of the clothing.

[0059] Different materials have different material thresholds.

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

[0061] Through the above methods, a light detection device is used to identify the material of clothing. Since the light detection device only needs to emit a light signal, it is less likely to fail to accurately identify the clothing material, thus improving the reliability and accuracy of clothing material identification. Furthermore, the identification result is obtained based on the calculation of the first light parameter when the light signal is emitted and the second light parameter after transmission through the load 4. Because different clothing materials consume light signals differently, the identification result can accurately reflect the clothing material of the load 4 inside the processing cylinder 1, further improving the accuracy of clothing material identification.

[0062] Optionally, calculating the change in optical parameters based on the first and second optical parameters corresponding to the operating optical detection device includes:

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

[0064] Based on the above, the change in optical parameters can be obtained by calculating the difference. The calculation process is simple, which helps to reduce the consumption of computing resources, reduce the cost of clothing material recognition, and improve the efficiency of clothing material recognition.

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

[0066] The step of calculating the difference between the first optical parameter and the second optical parameter corresponding to each operating optical detector to obtain the optical parameter change value of each operating optical detector includes:

[0067] The difference between the first light intensity and the second light intensity corresponding to each operating photodetector is calculated to obtain the change value of the optical parameters of each operating photodetector.

[0068] Based on the above, the calculation of light parameter changes is achieved using light intensity. Since different types of clothing have different effects on the light signal intensity, the light parameter changes obtained using light intensity are more likely to distinguish clothing materials, which helps to improve the accuracy of clothing material identification.

[0069] Optionally, obtaining the second optical parameters collected by the receiving electrode based on the operation of the photodetector includes:

[0070] When the processing cylinder is stationary, the controlled photodetector emits light signals multiple times to obtain multiple second light parameters, and / or,

[0071] The processing cylinder is controlled to rotate at least once and then remain stationary. The photodetector is controlled to emit light signals multiple times to obtain multiple second light parameters. The processing cylinder has a set maximum number of rotations.

[0072] The step of calculating the optical parameter change value based on the first and second optical parameters corresponding to the operating optical detection device includes:

[0073] Multiple optical parameter variation values ​​are calculated based on the first optical parameter and multiple second optical parameters corresponding to the operating optical detection device.

[0074] In other words, the processing cylinder will be controlled to rotate multiple times, and multiple tests will be performed after each rotation to obtain multiple second-stage parameters.

[0075] Based on the above, when the optical detector is controlling the operation to identify the material of clothing, it will emit light signals multiple times to obtain multiple second optical parameters. The processing cylinder can also be rotated to repeat the detection action of the optical detector, which can obtain multiple changes in optical parameters. On the one hand, the rotation of the processing cylinder can change the position and state of the internal load, making the second optical parameters more accurate. On the other hand, multiple detections help to improve the comprehensiveness of detection, reduce the false judgment rate, and improve the accuracy of clothing material identification.

[0076] Optionally, generating a recognition result characterizing the clothing material based on the matching relationship between the various light parameter changes and preset material thresholds includes:

[0077] Calculate the average value of the changes in multiple optical parameters corresponding to each operating optical detection device;

[0078] The average value is compared with the material threshold. If it is the same as the material threshold or within the threshold range of the material threshold, then a match is proven, 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 type of load and multiple photodetectors are in operation, the average value of each photodetector is calculated, and then the average values ​​of the multiple photodetectors are averaged to obtain an average value for comparison with the material threshold. Based on the comparison between this average value and the material threshold, the corresponding recognition result is generated.

[0080] In another embodiment, when there is a load of multiple materials and multiple photodetectors are in operation, the average value of each photodetector is calculated, and then the average value corresponding to each photodetector is compared with the material threshold to obtain the recognition result detected by each photodetector.

[0081] The above methods, which calculate the average value to obtain the recognition result, help improve the accuracy of clothing material recognition and reduce the consumption of computing resources.

[0082] Optionally, the method further includes:

[0083] The number of optical detectors that need to be operated is determined based on the load, wherein the larger the load, the larger the number of optical detectors that need to be operated.

[0084] Based on the above, under high load conditions, a larger number of optical detection devices operate, making it easier to ensure the accuracy of clothing material identification. Under low load conditions, a smaller number of optical detection devices operate, making it easier to save energy.

[0085] Optionally, determining the number of optical detectors that need to be operated based on the load includes:

[0086] Obtain the full load weight of the garment processing equipment and the load weight of the load 4, wherein the load includes the load weight;

[0087] The load amount is obtained by comparing the load weight with the full load weight;

[0088] The number of optical detectors that need to be operated is determined based on the load range to which the load belongs, wherein the larger the load range, the larger the number of optical detectors that need to be operated.

[0089] Based on the above, the load weight is easy to obtain and has high accuracy, which makes it easy to improve the accuracy of determining the number of optical detection elements.

[0090] Optionally, controlling the operation of at least one of the photodetectors includes:

[0091] If multiple photodetectors are operated, the emitters 2 of the multiple photodetectors are controlled to emit light signals one by one.

[0092] Through the above, multiple emitters 2 emit light signals one by one, avoiding interference between light signals emitted by different emitters 2, which helps to improve the accuracy of clothing material identification.

[0093] This embodiment also provides a garment processing device, such as... Figure 2As shown, it includes a processing cylinder 1, on which multiple sets of light detection elements are provided. Each light detection element includes an emitter 2 and a receiver 3. The emitter 2 is used to emit light signals to the receiver 3, and the receiver 3 is used to receive light signals that can be transmitted through the load 4 and generate corresponding light parameters.

[0094] The garment processing equipment uses the garment material identification method described above to identify the material of the garment.

[0095] Optionally, one of the emitter 2 and receiver 3 of the photodetector is disposed at the opening of the processing cylinder 1 and a plurality of emitters 2 are distributed along the circumference of the opening. The other of the emitter 2 and receiver 3 of the photodetector is disposed on the cylinder wall or bottom of the processing cylinder 1. The emitter 2 and receiver 3 of the photodetector are staggered so that when the emitter 2 emits a light signal to the associated receiver 3, the propagation path of the light signal is an inclined path relative to the cylinder wall of the processing cylinder.

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

[0097] The protective shell protects the emitter 2 and / or receiver 3, preventing water inside the treatment cylinder 1 from contacting the emitter 2 and / or receiver 3. Specifically, the protective shell is transparent.

[0098] Optionally, the garment processing equipment includes a top-loading washing machine.

[0099] Furthermore, for ease of understanding, the material identification based on light signal transmission is explained as follows: when a light signal comes into contact with clothing, transmission occurs. When a light signal is transmitted after contacting clothing, a transmission parameter value (equivalent to the second light parameter in this embodiment) can be obtained.

[0100] Specifically, transmission parameter values ​​can be the parameters of the transmitted light signal itself after transmission, such as the transmittance and intensity of the transmitted light signal, or they can be calculated from the parameters of the transmitted light signal itself, for example, by substituting the transmittance and / or intensity of the transmitted light signal into a preset calculation formula to obtain the transmission parameter values. In general, it is sufficient as long as different clothing materials correspond to different transmission parameter values.

[0101] In one embodiment, the preset calculation formula for calculating the transmission parameter value can be a formula that includes the wavelength and intensity of the transmitted light signal. For example, the transmission parameter value b = T% * φ luminous flux * power factor (intensity-related), and the transmittance T% = I (light intensity after transmission reduction) / IO (original light intensity) * 100%.

[0102] In one embodiment, in order to determine the material of the clothing, a transmission standard value range is preset (corresponding to the material threshold of this embodiment). Different transmission standard value ranges correspond to different clothing materials. In other words, the transmission standard value range and the clothing material are all related.

[0103] Specifically, the transmission standard value range is a numerical range composed of transmission standard values. It's important to note that transmission standard values ​​and transmission parameter values ​​are of the same type or obtained using the same algorithm. The difference lies in that transmission standard values ​​are obtained by conducting transmission experiments on clothing with known material properties, while transmission parameter values ​​are obtained by conducting transmission experiments on clothing during actual material identification. For ease of understanding, for example, during testing, formula B is used to calculate the transmittance and intensity of the transmitted light signal to obtain the transmission standard value. After multiple tests on clothing of material b, a numerical range Q1 can be defined based on all the obtained transmission standard values. In actual clothing material identification, formula B is also used to calculate the transmittance and intensity of the transmitted light signal to obtain the transmission parameter value. Since the calculation process for the transmission parameter value is the same as that for the transmission standard value, the clothing material can be determined based on the transmission parameter value.

[0104] The correspondence between transmission standard value ranges and clothing materials is as follows: each type of clothing material corresponds to a transmission standard value range, and different types of clothing materials correspond to different transmission standard value ranges. For example, material 'a' corresponds to the transmission standard value range Q1, which is the correspondence. This ensures that when the transmission parameter value is within Q1, the clothing material can be determined to be 'a'. Preferably, the correspondence obtained using an ultraviolet sensor includes: 10-13 corresponds to cotton, 13.5-15.5 corresponds to linen, 19-23 corresponds to wool, 16.5-18.9 corresponds to silk, 29-33 corresponds to polyester fiber, and 33.5-39 corresponds to synthetic fiber.

[0105] For ease of understanding, in one application scenario, the usage process of the clothing material identification method and clothing processing equipment in this embodiment is as follows:

[0106] Parameter description:

[0107] The light intensity λ1 emitted by emitter 2

[0108] The light intensity λ2 received by receiver 3

[0109] The preset values ​​for the difference in light intensity after transmission for each material are: Cotton: 70, Linen: 60, Silk: 30, Polyester: 40, Wool: 80, Synthetic Fiber: 50

[0110] Structural Description:

[0111] Control logic description:

[0112] The drum opening has multiple ultraviolet (UV) sensors at the emitter 2, emitting UV light with an initial intensity of λ1 and using a wavelength range of 100-400nm. Each UV sensor operates sequentially; simultaneous operation would affect the intensity λ2 of the light received by the receiver 3 after attenuation through the clothing. Each emitter 2 operates sequentially, and the receiver 3, directly opposite the empty drum, receives the UV light emitted by the directly opposite emitter 2. When the user places laundry into the drum, the motor at the bottom of the vertical drum of the pulsator weighs the laundry to determine if there is any laundry and whether the weight is half-full, less than half-full, or more than half-full.

[0113] If the load is less than half full, the 24 emitters 2 of the ultraviolet sensor around the drum opening will operate, with each emitter 2 spaced 90° apart, forming a circle around the drum opening to ensure that the detection coverage area covers the entire drum. After the emitter 2 emits light intensity λ1, it passes through the clothing, and the receiver 3 receives the transmitted ultraviolet light intensity λ2, calculates the light intensity difference Δλ, and feeds the light intensity difference back to the MCU chip on the main control board. The data is stored in the ROM memory inside the chip to realize the register function, so that the data can be called up later to calculate the average value. During detection, the drum cannot rotate. Each detection lasts for 10 seconds, and a measured value is taken every 1 second. After 10 detections, the light intensity difference Δλ of the 10 detections is converted by the algorithm logic of the main board to obtain the average value 'a', which is then compared with the preset values ​​for each material to determine what kind of clothing is inside the drum.

[0114] If the clothes inside the drum are half-loaded, eight ultraviolet (UV) electrodes at the drum opening will detect the clothes inside. Each adjacent emitter 2 will be 45° apart, forming a circumference around the drum opening to ensure coverage of the detection area. If the motor detects that the weight of the clothes inside the drum is a full load of 10kg, then twelve emitters 2 at the drum opening will be active, and correspondingly, twelve receivers 3 on the inner drum side wall will also be active.

[0115] For example, when testing clothing in the ultraviolet wavelength range of 100-400nm, emitter 2 emits light with an intensity of λ1. The motor detects the weight of the clothing at this point as half-loaded. If the drum is fully loaded with 10kg, then half-loaded is 5kg. Receiver 3 receives light with an intensity of λ2 after the ultraviolet light has passed through the clothing. This λ2 is then fed back to the mainboard for storage. After 10 consecutive measurements, the mainboard calculates the light intensity difference Δλ between emitter 2 and receiver 3 using an algorithm: Δλ = λ1 - λ2. The average Δλ of the first 10 measurements is 100. After the first measurement, the motor at the bottom of the drum rotates, causing the drum to rotate and agitate the clothing, initiating the second measurement. The light intensity difference Δλ is calculated again, with an average value of 70. After the second measurement, the clothing inside the drum is rotated again, and the average Δλ of the third measurement after transmission is obtained, with an average value of 130. In summary, the clothing material determined by the three measurements can be identified as either cotton or silk. Based on the detected material, the silk mode can be run. The mode should prioritize the materials that need more protection. After the washing time is halfway through, the AI ​​intelligent washing will be used to clean the clothes more thoroughly.
