[0044] like Figures 1-5As shown, the present invention provides a method for testing the balance of a washing machine. The washing machine includes a body 400 and a drum 410 horizontally disposed inside the body 400. A vibration damping component 430 is connected between the drum 410 and the bottom of the body 400. A first force gauge 421 and a second force gauge 422 are connected between the drum 410 and the top of the body 400. The first force gauge 421 and the second force gauge 422 are respectively connected to both sides of the drum 410. The first force gauge 421 and the second force gauge 422 are symmetrically arranged about the central axis of the drum 410. The method for testing the balance of the washing machine includes:
[0045] S100, after the washing equipment is turned on, the elasticity difference dataset between the first elasticity dataset and the second elasticity dataset is determined based on the first elasticity dataset of the first force gauge 421 within a preset time and the second elasticity dataset of the second force gauge 422 within a preset time.
[0046] The first elasticity dataset includes the elasticity values of the first force gauge 421 at various times within the preset duration; the second elasticity dataset includes the elasticity values of the second force gauge 422 at various times within the preset duration; the preset duration is a duration that can be adjusted in the controller of the washing equipment according to the actual situation, or multiple different durations can be pre-stored in the controller of the washing equipment as preset durations, and then a suitable duration can be selected as the preset duration according to the actual situation.
[0047] The elasticity difference dataset is a collection of the differences between the elasticity values of the first force gauge 421 and the second force gauge 422 within a preset time period, which can reflect the tilt of the roller 410.
[0048] S200, the elasticity difference dataset is processed to obtain the target dataset.
[0049] The controller of the washing equipment contains a pre-stored program for processing elasticity difference data. The target dataset can be obtained by processing the elasticity difference data according to the program.
[0050] S300: Substitute the target dataset into the preset neural network model to obtain the imbalance value of the washing equipment.
[0051] The controller of the washing equipment has a pre-stored neural network model, which is used to process the target dataset to obtain the imbalance value of the washing equipment. After obtaining the target dataset, it is only necessary to substitute it into the pre-stored neural network model to obtain the imbalance value of the washing equipment at the preset time, so as to determine the balance of the washing equipment based on the imbalance value.
[0052] The pre-built neural network model includes a three-layer network structure: an input layer, a hidden layer, and an output layer. The target dataset is input into the input layer, the hidden layer performs calculations on the target dataset, and finally the output layer outputs the result, i.e., the output layer outputs the imbalance value. The pre-built neural network model is trained using the gradient descent algorithm to obtain the optimal threshold neural network model.
[0053] Understandably, the washing equipment balance detection method is based on the first force gauge 421 and the second force gauge 422 symmetrically arranged on both sides of the drum 410. According to the first elastic force dataset and the second elastic force dataset of the first force gauge 421 and the second force gauge 422 within a preset time period, the elastic force difference dataset is determined. Then, the target dataset is obtained according to the elastic force difference dataset. Finally, the target dataset is substituted into the preset neural network model for processing to obtain the imbalance value of the washing equipment. According to the imbalance value, the balance of the washing equipment can be accurately determined.
[0054] In some embodiments, S200, the elasticity difference dataset is processed to obtain the target dataset, including:
[0055] S210, based on the elasticity difference dataset, obtain the first set of feature values.
[0056] The first feature set is a set of multiple data obtained by processing the elasticity difference dataset according to a preset program.
[0057] S220, process the first set of feature values to obtain the target dataset.
[0058] The target dataset is a collection of multiple data obtained by processing the data in the first feature value set according to a preset procedure.
[0059] In some embodiments, S210, a first set of feature values is obtained based on the elasticity difference dataset, including:
[0060] Based on the elasticity difference dataset, determine the first maximum value, the first minimum value, the difference between the first maximum value and the first minimum value, the first average value, the first root square magnitude, the first variance, the first standard deviation, and the first RMS effective value of the elasticity difference dataset.
[0061] The elastic force difference dataset includes: ΔF1, ΔF2, ΔF3, ... ΔF N .
[0062] Among them, the first maximum value is ΔF1, ΔF2, ΔF3, ... ΔF N The maximum value in the range, i.e., the first maximum value, is A1 = max(ΔF). N The first minimum value is ΔF1, ΔF2, ΔF3, ..., ΔF NThe minimum value, that is, the first minimum value, is A2 = min(ΔF). N ).
[0063] The difference between the first maximum value and the first minimum value is A3, where A3 = ΔF. max -ΔF min .
[0064] Among them, the first average value is
[0065] Wherein, the first root amplitude is
[0066] Wherein, the first variance is
[0067] The first standard deviation is:
[0068] The first RMS valid value is:
[0069] The first set of eigenvalues includes the first maximum value, the first minimum value, the difference between the first maximum value and the first minimum value, the first average value, the first root square magnitude, the first variance, the first standard deviation, and the first RMS effective value.
[0070] That is, the first set of eigenvalues includes A1, A2, A3, A4, A5, A6, A7, and A8.
[0071] Among them, RMS (Root Mean Square) is the effective value.
[0072] In some embodiments, S220, the first feature set is processed to obtain the target dataset, including:
[0073] S221, Determine the second mean and second standard deviation of the data in the first set of eigenvalues.
[0074] The first feature set is a collection of multiple processed data. For example, the first feature set includes A1, A2, A3, A4, A5, A6, A7, and A8.
[0075] That is, the second average is The second standard deviation is
[0076] S222, Based on the first set of eigenvalues, the second mean, and the second standard deviation, perform Z-score normalization on the first set of eigenvalues to obtain the target dataset.
[0077] Specifically, Z-score normalization of the first feature set requires performing Z-score normalization on each data point in the first feature set.
[0078] Z-score, or Z-score, is the standard score.
[0079] For example, the target data set can be obtained by processing the first feature value set in the above embodiment. The target data set includes B1, B2, B3, B4, B5, B6, B7, and B8.
[0080] Normalizing A1 yields the following result:
[0081] Similarly,
[0082] In some embodiments, S100, determining the elastic force difference dataset between the first elastic force dataset and the second elastic force dataset based on the first elastic force dataset of the first force gauge within a preset time period and the second elastic force dataset of the second force gauge within a preset time period includes:
[0083] S110, based on the first elastic force value corresponding to the first elastic force dataset and the second elastic force value corresponding to the second elastic force dataset at the same time, determine the absolute value of the difference between the first elastic force value and the second elastic force value.
[0084] The first elastic force value is F. A The second elastic force value is F B That is, ΔF i =|F Ai -F Bi |
[0085] Among them, F Ai Let F be the elastic force value of the first force gauge at time i. Bi Let be the elastic force value of the second force gauge at time i.
[0086] S120, Repeat the above steps to obtain the absolute value of the elasticity difference between the first elasticity dataset and the second elasticity dataset at different times of a preset duration.
[0087] Repeating the above steps yields ΔF1, ΔF2, ΔF3, ... ΔF. N .
[0088] Among them, ΔF can be determined by a fixed time interval. i This allows for the construction of an elastic force difference dataset by determining the absolute values of multiple elastic force differences; alternatively, it allows for the determination of ΔF at each moment based on a preset duration. i To construct an elasticity difference dataset.
[0089] The elasticity difference dataset includes the absolute values of the elasticity difference between the first elasticity dataset and the second elasticity dataset at different times within a preset duration.
[0090] Understandably, the elasticity difference dataset is constructed by calculating the absolute value of the elasticity difference at different times between the first elasticity dataset and the second elasticity dataset.
[0091] In some embodiments, the method for detecting the balance of a washing machine further includes:
[0092] S400: If the unbalance value is determined to be outside the preset unbalance value range, the preset time is shortened and the unbalance value is re-determined.
[0093] The preset imbalance value range is a range that exists in the washing equipment controller. When the imbalance value is within this range, the drum sway of the washing equipment can be considered to be within the normal range. Therefore, when the imbalance value is not within the preset imbalance value range, the imbalance value needs to be determined again to avoid misjudgment caused by other interference.
[0094] When the imbalance value is determined to be outside the preset imbalance value range, shortening the preset time can improve the accuracy of imbalance value determination and avoid other interferences that could lead to excessive errors in imbalance value determination.
[0095] In some embodiments, the method for detecting the balance of a washing machine further includes:
[0096] S500 will issue a maintenance alarm for the washing equipment after three consecutive determinations that the imbalance value is not within the preset imbalance value range.
[0097] If the imbalance value is determined to be outside the imbalance range three times in a row, the influence of other factors on the determination of the imbalance value can be basically ruled out. Therefore, it can be determined that there is a problem with the vibration damping component of the washing equipment, and it needs to be repaired.
[0098] In some embodiments, the present invention also provides a washing equipment stability detection device 10, including an acquisition module 100, a processing module 200, and a neural network module 300.

The processing module 200 is used to determine an elastic force difference dataset between the first elastic force dataset and the second elastic force dataset based on the first elastic force dataset from the first force gauge within the preset time period and the second elastic force dataset from the second force gauge within the preset time period. The processing module 200 is used to process the elastic force difference dataset to obtain a target dataset. The neural network module 300 is used to process the target dataset to obtain the imbalance value of the washing equipment.
