[0042] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention 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 numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in sequences other than those illustrated or described herein, for example.

[0045] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0046] With the continuous improvement of production technology and the continuous growth of user demand, users' requirements for clothing processing equipment are also getting higher and higher.

[0047] When existing clothing processing equipment fails during use and the user reports a repair, the maintenance personnel, when they come to handle the problem, often ask the user about the circumstances under which the failure occurred, and reproduce and analyze the circumstances under which the failure occurred based on the user's description. They determine the specific cause of the failure based on the results of the reproduction and analysis, and repair the clothing processing equipment based on the specific cause.

[0048] However, in actual usage scenarios, the occurrence of a fault may be caused by one or a series of low-probability events. After the fault occurs, the clothing processing equipment lacks a record of the immediate situation, resulting in a lack of effective basis for reproducing the situation where the fault occurred. In addition, the user's own knowledge of the equipment and the situation when the fault occurred is limited, and the maintenance personnel need to spend a lot of time to reproduce the situation when the fault occurred before repairing the clothing processing equipment, which wastes a lot of manpower and material resources. In addition, the accuracy of restoring the situation when the fault occurred is limited, which creates difficulties for subsequent repairs.

[0049] In response to the above problems, the present invention proposes the following technical concept: during the operation of the clothing processing equipment, an operating sound signal of the clothing processing equipment is collected, and based on the operating sound signal, a target sound signal matching the operating sound signal is retrieved from a large number of pre-stored operating sound samples; when the fault occurring in the clothing processing equipment is a fault recorded in the sound sample, the sound type of the target sound signal matching its operating sound signal is the fault type; at this time, the fault information corresponding to the target sound signal can be obtained and sent to the user terminal so that maintenance personnel can reproduce the fault based on the fault information.

[0050] Figure 1 Schematic diagram of the process of the method for handling a clothing processing device failure provided in the embodiment of the present application Figure 1 ;like Figure 1 As shown, the method for handling a fault of a clothing processing device provided in an embodiment of the present application includes:

[0051] S101: Acquire an operating sound signal of the laundry processing device, and retrieve a target sound signal matching the operating sound signal.

[0052] Among them, the operating sound signal refers to the sound signal collected in the surrounding environment of the clothing processing equipment during its operation, and the target sound signal matching the operating sound signal refers to the operating sound signal sample that is determined to have similar characteristics to the operating sound signal after comparison with the operating sound signal.

[0053] It can be understood that when the clothing processing equipment is in the same operating state, the operating sound signals emitted have certain similarities. Therefore, the operating sound signal samples corresponding to different operating states can be accumulated in advance through a large number of experiments and historical data, and the target sound signal matching the operating sound signal can be retrieved from the operating sound signal samples corresponding to the different operating states. The current operating state of the clothing processing equipment is determined according to the sound type of the target sound signal.

[0054] Specifically, during the operation of the clothing processing device, the clothing processing device obtains the operating sound signal through a sound collection device. The sound collection device can be a recording device arranged on the clothing processing device, or a recording device arranged in the surrounding environment of the clothing processing device. The embodiment of the present application does not limit the specific form and setting method of the sound collection device. The clothing processing device compares the operating sound signal with the pre-stored operating sound signal samples one by one for similarity. The method for comparing the similarity of the sound signals can, for example, be to comprehensively judge the similarity based on the waveform, zero-crossing rate, short-time energy, and spectrum value after spectrum FFT transformation of the sound signal, or to extract feature values ​​based on the audio parameters of the sound signal, and judge the similarity based on the feature values. The present embodiment does not limit the specific method for comparing the similarity of the sound signals.

[0055] S102: If a target sound signal matching the running sound signal is retrieved, the sound type corresponding to the target sound signal is obtained.

[0056] Among them, the sound type corresponding to the sound signal is used to indicate the operating state of the clothing processing device when the clothing processing device sends the sound signal, that is, whether a fault occurs or not; the sound types of the pre-stored operating sound signal samples are divided into fault type and non-fault type, and the fault type sound is the operating sound signal when the clothing processing device fails, such as a part of the clothing processing device is damaged, and the abnormal noise signal is emitted when it is running; or there is a foreign object in the inner drum of the clothing processing device, and when the clothing processing device is running, its operating sound signal contains the impact sound emitted when the foreign object hits the inner drum, etc. The non-fault type sound is the operating sound signal when the clothing processing device is operating normally, such as the sound signal emitted by the water intake, washing, drainage, and dehydration when the clothing processing device executes the washing program; or the ambient noise signal in the surrounding environment that is unrelated to the clothing processing device; or when there are buttons and zippers on the clothes, the operating sound signal contains the impact sound emitted when they hit the inner drum, etc.

[0057] A sound signal sample whose similarity reaches a preset requirement is obtained as the target sound signal, and the sound type corresponding to the target sound signal is obtained according to the pre-stored correspondence between the sound signal sample and the sound type.

[0058] S103: If the sound type is a fault type, acquiring fault information corresponding to the target sound signal, and sending the fault information to a user terminal.

[0059] Among them, the fault information is used to reproduce the fault of the clothing processing equipment. The fault information can be, for example, the components corresponding to the structure causing the fault and the positions of the components, or it can be a set of probabilistic events required for the program running that causes the fault. This embodiment does not limit the specific content form of the fault information.

[0060] It can be understood that when the sound type of the retrieved target sound signal is a fault type, the maintenance personnel need to analyze and reproduce the cause of the fault. Because the target sound signal has a certain similarity with the operating sound signal of the clothing processing equipment, it can be judged that the cause of the fault is consistent with the fault cause corresponding to the target sound signal. Therefore, different fault information and the correspondence between the different fault information and each sound signal can be pre-stored. When the same fault occurs, the fault information corresponding to the target sound signal is output according to the matched target sound signal to help maintenance personnel analyze and reproduce the cause of the fault.

[0061] Specifically, when the sound type is a fault type, the clothing processing device obtains the fault information corresponding to the target sound signal according to the correspondence between the pre-stored fault information and each sound signal, and sends the fault information to the user terminal. The method of sending the fault information may, for example, be to control the application pre-installed on the user terminal to send a push message through the near field communication function of the user terminal, a wireless local area network, or a mobile communication network. This embodiment does not limit the specific method of sending the fault information to the user terminal.

[0062] The clothing processing equipment fault handling method provided in the present embodiment obtains the operating sound signal of the clothing processing equipment and retrieves the target sound signal matching the operating sound signal. When the target sound signal matching the operating sound signal is retrieved, the sound type corresponding to the target sound signal is obtained; if the sound type is a fault type, the fault information corresponding to the target sound signal is obtained, and the fault information is used to reproduce the fault of the clothing processing equipment. The fault information is sent to the user terminal to help maintenance personnel analyze and reproduce the cause of the fault, thereby improving the accuracy of fault analysis and reproduction and the effectiveness of subsequent fault repair, saving a lot of manpower and material resources, and thus improving the user experience of the clothing processing equipment.

[0063] Figure 2 Schematic diagram of the process of the method for handling a clothing processing device failure provided in the embodiment of the present application Figure 2 ;like Figure 2 As shown, the method for handling a fault of a clothing processing device provided in an embodiment of the present application includes:

[0064] S201: Acquire an operation sound signal of the clothing processing device, a clothing processing device identifier, a clothing processing program, and an operation stage.

[0065] Among them, the operating sound signal refers to the sound signal collected in the surrounding environment of the clothing processing equipment during its operation, the clothing processing equipment identifier is used to indicate the model of the clothing processing equipment, the clothing processing program is a pre-set operating mode of the clothing processing equipment, such as a cotton and linen washing program, a clothing disinfection program, etc., and the operating stage is the different time periods of the clothing processing program. For example, the operating stages of the cotton and linen washing program include a washing stage, a rinsing stage and a dehydration stage.

[0066] Specifically, during the operation of the clothing processing device, the clothing processing device obtains the operating sound signal through a sound collection device, and obtains the device identification of the clothing processing device, the clothing processing program being executed, and the operating stage being executed in the clothing processing program.

[0067] S202: Acquire a sound database corresponding to the laundry processing device identifier, the laundry processing program, and the operation stage, and retrieve a target sound signal matching the operation sound signal from the sound database.

[0068] It can be understood that there are significant differences in the characteristics of the operating sound signals emitted by different models of clothing processing devices, and when the clothing processing devices are executing different clothing processing programs / different operating stages of the same clothing processing program. Therefore, the operating sound signals can be distinguished based on the clothing processing device identification, clothing processing program and operating stage, and the operating sound signals of different clothing processing devices when executing different clothing processing programs at different operating stages are stored in the sound database respectively, and a correspondence between different operating sound signals and different clothing processing device identifications, clothing processing programs and operating stage sets is established to improve the matching accuracy.

[0069] Optionally, the clothing processing device obtains a sound database corresponding to the clothing processing device identification, clothing processing program and operation stage in a local database, and retrieves a target sound signal matching the operation sound signal in the local sound database.

[0070] If the target sound signal matching the operating sound signal is not retrieved in the sound database corresponding to the local database, the sound database corresponding to the clothing processing equipment identifier, clothing processing program and operating stage is obtained in the remote database, and the target sound signal matching the operating sound signal is retrieved in the remote sound database.

[0071] It can be understood that the use of a local database has the advantages of simple calling and fast response speed, but due to the constraints of hardware resource costs, the storage capacity of the local database is usually limited. Therefore, the more common operating sound signal samples can be stored in the sound database corresponding to the local database, and the operating sound signal samples with a lower probability of occurrence can be stored in the remote database. When matching the target sound signal, the sound database corresponding to the local database is searched first. If the target sound signal matching the operating sound signal is not retrieved in the sound database corresponding to the local database, the sound database corresponding to the remote database is searched for the target sound signal matching the operating sound signal.

[0072] Specifically, the clothing processing device obtains a sound database corresponding to the clothing processing device identification, clothing processing program and operating stage in a local database according to the correspondence between different operating sound signals and different clothing processing device identifications, clothing processing programs and operating stage sets, and retrieves a target sound signal matching the operating sound signal from the local sound database; if the target sound signal matching the operating sound signal is not retrieved in the sound database corresponding to the local database, then through a communication connection with a remote database, obtains a sound database corresponding to the clothing processing device identification, clothing processing program and operating stage in the remote database according to the correspondence between different operating sound signals and different clothing processing device identifications, clothing processing programs and operating stage sets, and retrieves the target sound signal matching the operating sound signal from the remote sound database.

[0073] S203: If a target sound signal matching the running sound signal is retrieved, the sound type corresponding to the target sound signal is obtained.

[0074] The implementation of step S203 is similar to that of step S102, and will not be described in detail in this embodiment.

[0075] S204: If the sound type is a fault type, determine whether the fault type is a fault that affects the continued operation of the clothing processing device. If so, send an alarm message and control the clothing processing device to stop running; if not, send an alarm message and control the clothing processing device to continue executing the current clothing processing program.

[0076] Among them, the fault that affects the continued operation of the clothing processing device refers to a fault that may further cause adverse consequences if the clothing processing device continues to operate after the fault occurs. For example, if the fault is caused by a ruptured drain pipe, if the clothing processing device continues to operate, it may cause water to leak from the drain pipe, thereby causing adverse consequences such as a short circuit; and if the fault occurs, for example, the clothes are entangled in the inner drum, and the running noise caused by the collision with the box is loud, if the clothing processing device continues to operate, it will not cause further adverse consequences. Therefore, it can be determined whether the fault type is a fault that affects the continued operation of the clothing processing device; if so, an alarm message is sent, and the clothing processing device is controlled to stop operating to prompt the user that a fault has occurred and avoid the adverse consequences that may be caused by the continued operation of the clothing processing device; if not, an alarm message is sent, and the clothing processing device is controlled to continue to execute the current clothing processing program to prompt the user that a fault has occurred, and the fault information can be checked, and the fault can be processed after the clothing processing program ends to avoid the inconvenience caused by the termination of the clothing processing program.

[0077] Specifically, if the sound type is a fault type, the clothing processing device determines whether the fault type is a fault that affects the continued operation of the clothing processing device based on pre-set fault category information. If so, an alarm message is sent and the clothing processing device is controlled to stop running; if not, an alarm message is sent and the clothing processing device is controlled to continue executing the current clothing processing program. The method of sending the alarm message may, for example, be to control an application pre-installed on the user terminal to send a push message through the near-field communication function of the user terminal, a wireless local area network, or a mobile communication network, or to control an audio playback device of the clothing processing device to issue an alarm prompt audio. This embodiment does not limit the specific method of sending the alarm message.

[0078] S205: Acquire fault information corresponding to the target sound signal, and send the fault information to a user terminal.

[0079] The fault information is used to reproduce the fault of the clothing processing device.

[0080] It is understandable that the researchers and developers of clothing processing equipment have accumulated a certain amount of fault information through a large number of experimental verifications, user usage data, and after-sales maintenance records. Therefore, different fault information and its correspondence with operating sound signals can be pre-stored. After determining the fault type corresponding to the target sound signal, the fault information corresponding to the target sound signal is obtained from the storage location of the fault information according to the correspondence, and the fault information is sent to the user terminal.

[0081] Optionally, if the fault type is a structural fault, the fault information includes the faulty component, the fault cause and the disassembly inspection steps.

[0082] If the fault type is a program fault, the fault information includes a program fault identifier, a probability of occurrence of the program fault, and a method for reproducing the program fault.

[0083] The method for reproducing the program fault is the working condition when the fault occurs, for example, it can be a set of determination conditions of all algorithm programs being executed by the clothing processing device when the fault occurs.

[0084] It is understandable that there are many causes for different faults, and the causes of faults can generally be divided into two categories. One is the abnormality of the hardware structure of the clothing processing equipment, and the other is the program abnormality when the clothing processing equipment executes the control algorithm. For the above two types of fault causes, there are great differences in the processing logic for reproduction and maintenance.

[0085] For structural failures caused by hardware structural abnormalities, when reproducing and repairing the failure, it is usually necessary to disassemble the entire clothing processing equipment, inspect the entire machine components, locate the position of the component with structural failure, and repair or replace the component. Therefore, when the fault type is a structural failure, the output fault information may include the faulty component, the cause of the fault and the disassembly inspection steps, so that maintenance personnel can directly locate the faulty component with reference to the faulty component and the cause of the fault, saving the time of disassembling the entire clothing processing equipment and inspecting the entire machine components. At the same time, referring to the disassembly inspection steps can help maintenance personnel reduce unnecessary actions and invalid steps during disassembly inspection, thereby improving the efficiency of handling structural failures.

[0086] For program failures caused by abnormal execution of algorithm programs, since the execution status of the algorithm programs in the control device of the clothing processing equipment is invisible to maintenance personnel and users during use, the specific cause of the program failure cannot be determined by direct observation methods. It is usually necessary to repeatedly execute the algorithm program being executed when the failure occurs, and cooperate with the observation of the corresponding phenomena of the hardware structure of the clothing processing equipment to locate the abnormal algorithm program through the corresponding phenomena of the hardware structure. However, the time required for repeatedly executing the program is closely related to the abnormal program range estimated at the beginning of the test, and some program abnormalities are caused by one or a series of low-probability events. When reproducing, it is necessary to repeat the execution of the program to be tested dozens or even hundreds of times, which consumes a lot of human and material resources. If the fault type is a program fault, the output fault information can include the probability of program fault occurrence and the method for reproducing the program fault, so that maintenance personnel can more accurately estimate the number of executions and time required to successfully reproduce the program fault with reference to the probability of program fault occurrence. With reference to the method for reproducing the program fault, the working conditions when the fault occurs can be accurately reproduced to trigger the reproduction of the program fault as soon as possible, thereby improving the efficiency of handling program faults.

[0087] For example, a certain model of clothing processing equipment is equipped with a control rod structure. When executing the dehydration stage of the washing program, when the outer drum has a large up and down movement, the outer drum will hit the control rod, push the control rod structure to rotate, and then trigger the safety switch. When the safety switch is triggered, the eccentricity control algorithm of the clothing processing equipment will determine that the spinning drum is eccentric, and then control the motor to cut off the power, and then execute the water rinsing program to correct the eccentricity; the clothing processing equipment is also equipped with an acceleration sensor next to the outer drum. When executing the dehydration stage of the washing program, when the acceleration of the outer drum rotation detected by the acceleration sensor is abnormal, the acceleration control algorithm of the clothing processing equipment will also control the motor to cut off the power.

[0088] When the control lever of the clothing processing device triggers the safety switch and the acceleration sensor detects the abnormal acceleration of the outer drum rotation, the clothing processing device will receive two motor power-off instructions. The eccentric control algorithm controls the clothing processing device to perform the water rinsing program based on the motor power-off instruction. When the motor power-off instructions are received twice, the eccentric control algorithm will perform the water rinsing program twice, which will cause the clothing processing device to mistakenly perform the water rinsing program twice. For the above-mentioned program failure, the corresponding method of reproducing the program failure is that the control lever of the clothing processing device triggers the safety switch and the acceleration sensor detects the abnormal acceleration of the outer drum rotation. The probability of the program failure is the probability of the two probability events occurring at the same time. Through the analysis of a large number of experiments and historical data, the R&D personnel determined that the probability of the two probability events occurring at the same time to trigger the failure is 1 / 400, and stored the fault information corresponding to the above-mentioned program failure in the storage location of the fault information.

[0089] For the above-mentioned program failure, the duration of the sound signal corresponding to the water inlet and rinsing stage of the clothing processing equipment is too long. The fault information obtained by the clothing processing equipment may be, for example, the program failure identifier, the probability of occurrence of the program failure = 1 / 400, and the method for reproducing the program failure is that the control lever of the clothing processing equipment triggers the safety switch and the acceleration sensor detects abnormal acceleration of the outer drum rotation.

[0090] S206: If the operation sound signal is not retrieved, the operation information is stored, where the operation information includes the operation sound signal and its corresponding clothing equipment identification, clothing processing program and operation stage.

[0091] It is understandable that when the operating sound signal is not retrieved, it is impossible to directly determine the operating status of the clothing processing equipment and the specific cause of the possible fault. At this time, the operating sound signal and its corresponding clothing equipment identification, clothing processing program and operating stage can be stored to provide maintenance personnel with sufficient judgment basis for identifying and handling faults, thereby reducing the time and energy costs required for judgment and speculation.

[0092] Specifically, if the operating sound signal is not retrieved, the clothing processing device stores the current operating information in a readable storage device. The storage device can be set on the clothing processing device or a remote storage device that is communicatively connected to the clothing processing device. This embodiment does not limit the specific method of storing the operating information.

[0093] S207: Sending an alarm message to the user terminal, and controlling the clothing processing device to stop running.

[0094] It is understandable that when the operating sound signal is not retrieved, it is impossible to directly determine the operating status of the clothing processing equipment and the specific cause of the possible failure, nor is it possible to accurately estimate the potential risks of continuing to operate the clothing processing equipment. Therefore, an alarm message can be sent and the clothing processing equipment can be controlled to stop running to prompt the user that an abnormality has occurred and avoid the adverse consequences that may be caused by continuing to operate the clothing processing equipment.

[0095] Among them, the user terminal user feeds back the fault type and the corresponding fault information to the remote database, so that the remote database associates and stores the operating sound signal and the corresponding fault type and fault information in the sound database corresponding to the clothing equipment identification, clothing processing program and operating stage, and regularly updates the sound database in the local database.

[0096] It is understandable that, since the clothing processing equipment itself and its surrounding environmental conditions are diverse and constantly changing when it is running, even if the fault is the same, the characteristics of its operating sound signal will be different. Therefore, the user terminal user can be allowed to feedback the fault type and corresponding fault information to the remote database, so that the remote database can associate the operating sound signal with the corresponding fault type and fault information and store them in the sound database corresponding to the clothing equipment identification, clothing processing program and operating stage, and regularly update the sound database in the local database to continuously expand the number of samples in the sound database, so that the sound database can be continuously improved to improve the accuracy of matching the target sound signal.

[0097] The fault handling method for clothing processing equipment provided in the embodiment of the present application obtains the operating sound signal of the clothing processing equipment, and obtains the target sound signal matching the operating sound signal in the local database and the remote database, thereby taking into account the matching efficiency and a certain matching success rate; obtains the fault information corresponding to the target sound signal, and sends the fault information to the user terminal, so as to help maintenance personnel locate the root cause of the fault as soon as possible, reduce invalid operations, and improve the efficiency and accuracy of handling structural faults; feeds back the acquired fault type and corresponding fault information to the remote database, so that the remote database associates the operating sound signal with the corresponding fault type and fault information and stores them in the sound database corresponding to the clothing equipment identification, clothing processing program and operating stage, and regularly updates the sound database in the local database, so that the sound database can be continuously improved to improve the accuracy of matching the target sound signal.
