[0009] According to the disclosed invention, after obtaining a first noise signal at the location of a target staff member in a target workplace during a first period, the overall control parameters of multiple signal transmitters during a second period (a future period of the first period) can be predicted based on the first noise signal to obtain a current parameter prediction result.

[0011] It should be understood that the contents described in the Summary of the Invention section do not limit the key points or important features of the embodiments of the present disclosure, nor do they limit the scope of the present disclosure. Other features of the present disclosure will be easily understood from the following description.

[0012] In the drawings, unless otherwise specified, the same reference numerals in multiple views indicate the same or similar parts or elements. The drawings are not necessarily drawn to scale. It should be understood that the drawings merely illustrate some embodiments provided by the present disclosure and are not to be considered as limiting the scope of the present disclosure.

[0013] The present disclosure will now be described in more detail with reference to the drawings, in which like reference numerals indicate functionally identical or similar elements, and in which various aspects of the embodiments are shown, but which are not necessarily drawn to scale unless otherwise noted.

[0014] Furthermore, in order to better explain the present disclosure, numerous specific details are described in the following specific embodiments. Those skilled in the art should understand that the present disclosure can be similarly implemented without specific details. In some instances, methods, means, elements, circuits, etc. that are well known to those skilled in the art are not described in detail, so as to emphasize the gist of the present disclosure.

[0015] As mentioned above, in an industrial spinning process, the complexity and length of the process flow mean that multiple production workshops with different functions are required. Furthermore, a huge number of process equipments are installed in each production workshop, and significant noise pollution occurs when these process equipments operate. For example, in a spinning workshop that produces wound yarn package products, a huge number of spinning boxes, which are process equipments, are installed therein, and significant noise pollution occurs when these spinning boxes operate. Furthermore, in a winding workshop that winds wound yarn package products, a huge number of winders, which are process equipments, are installed therein, and significant noise pollution occurs when these winders operate.

[0016] To reduce noise pollution in a production workplace, an embodiment of the present disclosure provides a noise processing method, which is applied to an electronic device, which communicates with a plurality of signal generators arranged in a target workplace, and the arrangement manner of the plurality of signal generators in the target workplace correlates with a real-time noise sound field in the target workplace, where the target workplace can be any one of a plurality of production workplaces with different functions related to the spinning process, and the signal generator can be a speaker.

[0017] In the embodiments of the present disclosure, the main types of wound yarn package products may include at least one of partially oriented yarns (POY), fully drawn yarns (FDY), drawn textured yarns (DTY) (also referred to as low stretch yarns), etc. For example, the types of wound yarn package products may specifically include polyester partially oriented yarns, polyester fully drawn yarns, polyester drawn yarns, polyester low stretch yarns (Polyester Draw Textured Yarns), etc.

[0018] 1 is a schematic flowchart 1 of a noise processing method according to an embodiment of the present disclosure. The noise processing method according to an embodiment of the present disclosure will now be described with reference to FIG. 1. Note that although a logical order is shown in the schematic flowchart, in some cases the steps shown or described may be performed in a different order.

[0019] Step S101: Obtain a first noise signal of the location of a target staff member in a target workplace within a first period.

[0020] Here, the first period may be a current period having a time length equal to a first predetermined time length. In one example, the first predetermined time length is determined according to the movement speed of the target staff member. For example, the first predetermined time length may be negatively correlated with the movement speed of the target staff member, i.e., the faster the movement speed of the target staff member, the shorter the first predetermined time length, and the slower the movement speed of the target staff member, the longer the first predetermined time length.

[0021] In an embodiment of the present disclosure, the target staff member may be a worker entering the target workplace, and the first noise signal may be a real-time noise signal felt by the target staff member within a first period of time. In one example, the first noise signal is collected by a first pickup attached to the target staff member and transmitted to an electronic device. The first pickup may be an electromagnetic pickup, a piezoelectric pickup, a fiber optic pickup, a digital pickup, or the like.

[0022] Step S102: Predict the overall control parameters of the multiple signal generators in a second period according to the first noise signal, and obtain a current parameter prediction result.

[0023] The second time period is a future time period of the first time period. For example, the second time period may be a future time period of the first time period, the time length of which is a second predetermined time length. In an embodiment of the present disclosure, the second predetermined time length may be the same as the first predetermined time length or may be different from the first predetermined time length. In one example, the second predetermined time length is determined according to the movement speed of the target staff member. For example, the second predetermined time length may be negatively correlated with the movement speed of the target staff member, i.e., the faster the movement speed of the target staff member, the shorter the second predetermined time length, and the slower the movement speed of the target staff member, the longer the second predetermined time length.

[0024] In addition, in the embodiment of the present disclosure, the current parameter prediction result is used to control the operating state of each signal generator within the second period.

[0025] Step S103: Based on the current parameter prediction result, determine one or more target transmitters that need to operate within the second period from the multiple signal transmitters, and obtain the parameter prediction value within the second period for each target transmitter.

[0026] The current parameter prediction result is used to control the operating state of each signal generator within the second time period, so that for each signal generator, it is possible to determine whether the signal generator is a target generator that needs to operate within the second time period based on the current parameter prediction result, and obtain parameter prediction values ​​within the second time period for each target generator, where the parameter prediction values ​​may include a frequency prediction value, a phase prediction value, an amplitude prediction value, and a direction prediction value.

[0027] Step S104: Control each target transmitter to emit a noise interference signal within the second period according to the corresponding parameter prediction value, so as to weaken the second noise signal at the location of the target staff in the target workplace within the second period.

[0028] Here, the second noise signal may be a real-time noise signal that is sensed by the target person within the second period.

[0029] When each target transmitter is controlled to emit a noise interference signal within a second period according to the corresponding parameter predicted value, the noise interference signal can have a canceling effect on the second noise signal at the target staff's location in the target workplace within the second period, thereby weakening the second noise signal at the target staff's location in the target workplace within the second period.

[0030] According to the disclosed invention, after obtaining a first noise signal at the location of a target staff member in a target workplace during a first period, the overall control parameters of multiple signal transmitters during a second period (a future period of the first period) can be predicted based on the first noise signal to obtain a current parameter prediction result. The current parameter prediction result is obtained by prediction based on the first noise signal, and is not obtained by directly analyzing the first noise signal, with the aim of establishing a strong correlation with the second period. Therefore, based on the current parameter prediction result, one or more target transmitters from the multiple signal transmitters that need to be activated during the second period can be determined. After obtaining parameter prediction values ​​for each target transmitter during the second period, each target transmitter can be controlled to emit noise interference signals during the second period according to the corresponding parameter prediction values, which can have a good canceling effect on the second noise signal at the location of the target staff member in the target workplace during the second period, thereby weakening the second noise signal at the location of the target staff member in the target workplace during the second period and thereby reducing noise pollution in the target workplace.

[0031] 2 is a schematic flowchart 2 of a noise processing method according to an embodiment of the present disclosure. The noise processing method according to an embodiment of the present disclosure will now be described with reference to FIG. 2. Note that although a logical order is shown in the schematic flowchart, in some cases the steps shown or described may be performed in a different order.

[0032] Step S201: Obtain a first noise signal of the location of a target staff member in a target workplace within a first period.

[0033] The first period may be a current period having a time length equal to a first predetermined time length. In one example, the first predetermined time length is determined according to the moving speed of the target staff member. For example, the first predetermined time length may be negatively correlated with the moving speed of the target staff member, i.e., the faster the moving speed of the target staff member, the shorter the first predetermined time length, and the slower the moving speed of the target staff member, the longer the first predetermined time length.

[0034] In an embodiment of the present disclosure, the target staff member may be a worker entering the target workplace, and the first noise signal may be a real-time noise signal sensed by the target staff member within a first period of time. In one example, the first noise signal is collected by a first pickup attached to the target staff member and transmitted to an electronic device. Here, the first pickup may be an electromagnetic pickup, a piezoelectric pickup, a fiber optic pickup, a digital pickup, or the like.

[0035] Step S202: Construct a first feature sequence based on the first noise signal and the historical parameter prediction result.

[0036] Here, the historical parameter prediction result is a prediction of the overall control parameters of the multiple signal transmitters during a first time period based on the zeroth noise signal at the location of the target staff member in the target workplace during a zeroth time period, where the zeroth time period is a history time period of the first time period. For example, the zeroth time period may be a history time period of the first time period having a third predetermined time length. In an embodiment of the present disclosure, the third predetermined time length may be the same as or different from the first predetermined time length. In one example, the third predetermined time length is determined according to the movement speed of the target staff member. For example, the third predetermined time length may be negatively correlated with the movement speed of the target staff member. That is, the faster the movement speed of the target staff member, the shorter the third predetermined time length, and the slower the movement speed of the target staff member, the longer the third predetermined time length.

[0037] In the embodiment of the present disclosure, the historical parameter prediction result is used to control the operating state of each signal generator within the first time period. More specifically, for each signal generator, historical transmission parameters of the signal generator within the first time period are obtained based on the historical parameter prediction result.

[0038] The historical transmission parameters may include a frequency value, a phase value, an amplitude value, and a direction value.

[0039] In an alternative embodiment, step S202 may include the following steps.

[0040] Step S202-1: Obtain a time-ordered noise signal sequence based on a first noise signal.

[0041] In one example, the time-ordered noise signal sequence obtained based on the first noise signal is {X 11 ,X 12 ,···,X 1n}, where X 11 is the time T in the first period 11 The noise data of the target staff position in the target workplace is shown, specifically the frequency value F 11 , phase value P 11 , amplitude value A 11 and direction value D 11 may include X 12 is the time T in the first period 12 The noise data of the target staff position in the target workplace is shown, specifically the frequency value F 12 , phase value P 12 , amplitude value A 12 and direction value D 12 Similarly, the following may include X 1n is the time T in the first period 1n The noise data of the target staff position in the target workplace is shown, specifically the frequency value F 1n , phase value P 1n , amplitude value A 1n and direction value D 1n may include:

[0042] Step S202-2: Based on the historical parameter prediction result, a known parameter sequence arranged in time order is obtained.

[0043] In one example, the number of signal generators in the target workplace is K (K≧2 and is an integer), and the known parameter sequence may include K known parameter subsequences that correspond one-to-one to the K signal generators, and the known parameter subsequence corresponding to the i-th signal generator among the K signal generators is {Qi 11 ,Qi 12 ,···,Qi 1n}, where 1≦i≦K and i is a positive integer.

[0044] Here, for i=1, Q1 11 is the time T in the first period 11 , the historical parameter prediction value of the first signal generator among the K signal generators, specifically, the frequency prediction value F1 11 , phase prediction value P1 11 , amplitude prediction value A1 11 and directional prediction value D1 11 Q1 12 is the time T in the first period 12 , the historical parameter prediction value of the first signal generator among the K signal generators, specifically, the frequency prediction value F1 12 , phase prediction value P1 12 , amplitude prediction value A1 12 and directional prediction value D1 12 Similarly, the following may include Q1 1n is the time T in the first period 1n , the historical parameter prediction value of the first signal generator among the K signal generators, specifically, the frequency prediction value F1 1n , phase prediction value P1 1n , amplitude prediction value A1 1n and directional prediction value D1 1n It may also include.

[0045] For other values ​​of i, Qi 11 ,Qi 12 ,···,Qi 1n The above can be understood by referring to the related content, and detailed description thereof will be omitted here.

[0046] Step S202-3: Splice the known parameter sequence into the noise signal sequence to obtain a first initial sequence.

[0047] Step S202-4: Obtain a first additional feature based on the real-time task information of the target workplace.

[0048] Here, the real-time task information may include the product type, product specifications, etc. of the wound yarn package product processed at the target workshop. In addition, in an embodiment of the present disclosure, operating parameters used when the process equipment at the target workshop operates can be obtained based on the real-time task information. If the target workshop is a spinning workshop, the process equipment at the target workshop is a spinning box, and the operating parameters used when the spinning box operates may include the specification parameters of the spinneret in the spinning box, the spinning speed, etc. If the target workshop is a winding workshop, the process equipment at the target workshop is a winding machine, and the operating parameters used when the winding machine operates may include the brand, specification parameters, winding speed, number of winding heads, etc.

[0049] Based on this, in one example, the real-time task information of the target workplace and the first workplace indicator can both be the first additional feature, or the operating parameters used when the process equipment in the target workplace operates and the first workplace indicator of the target workplace can both be the first additional feature, where the first workplace indicator of the target workplace can be used to determine the processing task type, workplace location, etc. of the target workplace, and the processing task type can include producing a wound yarn package product, winding a wound yarn package product, etc.

[0050] Step S202-5: Construct a first feature sequence based on the first initial sequence and the first additional feature.

[0051] Continuing with the previous example, the noise signal sequence is {X 11 ,X 12 ,···,X 1n}, where the number of signal generators in the target factory is K (K≧2 and is an integer), and the known parameter sequence may include K known parameter subsequences that correspond one-to-one to the K signal generators, and the known parameter subsequence corresponding to the i-th signal generator among the K signal generators is expressed as {Qi 11 ,Qi 12 ,···,Qi 1n}, where 1≦i≦K, and i is a positive integer. When the first additional feature includes real-time task information of the target workplace and a first distance indicator, the first feature sequence constructed based on the first initial sequence obtained by stitching the known parameter sequence to the noise signal sequence and the first additional feature obtained based on the real-time task information of the target workplace may include feature data as shown in Table 1.

[0052] [Table 1]

[0053] where Y 11 is the time T in the first period 11 This shows the real-time task information of the target workplace at time T 11 Product type Ty of wound yarn package products processed at the target workplace 11 , Product Specifications Sp 11 etc., Y 12 indicates the real-time task information of the target workplace at a time within the first period, specifically, at time T 12 Product type Ty of wound yarn package products processed at the target workplace 12 , Product Specifications Sp1 12 etc., and the following may also include Y 1n is the time T in the first period 1n This shows the real-time task information of the target workplace at time T 1n Product type Ty of wound yarn package products processed at the target workplace 1n, Product Specifications Sp 1n etc., where Wid indicates the first workplace mark of the target workplace.

[0054] Thus, in an embodiment of the present disclosure, the first feature sequence not only includes a first initial sequence obtained by splicing a known parameter sequence into a noise signal sequence, but also can include a first additional feature obtained based on real-time task information of the target workplace, thereby ensuring the integrity of the feature data included in the first feature sequence and thereby increasing the reliability of the current parameter prediction results.

[0055] Step S203: Construct a second feature sequence based on the historical parameter prediction result and the future parameter sequence.

[0056] The prediction results of the historical parameters can be understood by referring to the related content above, and a detailed description thereof will be omitted here.

[0057] In the embodiment of the present disclosure, the future parameter sequence is an input sequence corresponding to the current parameter prediction result, and the sequence length of the future parameter sequence may be the same as or different from the sequence length of the known parameter sequence.

[0058] Continuing with the above example, the number of signal generators in the target workplace is K (K≧2 and is an integer), and the future parameter sequence may similarly include K future parameter subsequences that correspond one-to-one to the K signal generators, and the future parameter subsequence corresponding to the i-th signal generator among the K signal generators is {Zi 21 ,Zi 22 ,···,Zi 2n}, where 1≦i≦K and i is a positive integer.

[0059] Here, when i=1, Z1 21 is the time T in the second period21 , the data element corresponding to the parameter prediction value of the first signal generator among the K signal generators, specifically the frequency prediction value F1 21 The data element corresponding to the phase prediction value P1 21 The data element corresponding to the amplitude prediction value A1 21 The data element and the direction prediction value D1 corresponding to 21 and the values ​​of these four elements may be any set value, for example, 0, and Z1 22 is the time T in the second period 22 , the data element corresponding to the parameter prediction value of the first signal generator among the K signal generators, specifically the frequency prediction value F1 22 The data element corresponding to the phase prediction value P1 22 The data element corresponding to the amplitude prediction value A1 22 The data element and the direction prediction value D1 corresponding to 22 and the values ​​of these four elements may be any set value, for example, 0. Similarly, Z1 2n is the time T in the second period 2n , the data element corresponding to the parameter prediction value of the first signal generator among the K signal generators, specifically the frequency prediction value F1 2n The data element corresponding to the phase prediction value P1 2n The data element corresponding to the amplitude prediction value A1 2n The data element and direction prediction value D1 corresponding to 2n may include data elements corresponding to

[0060] For other values ​​of i, Zi 21 ,Zi 22 ,···, Zi 2n The above can be understood by referring to the related content, and detailed description thereof will be omitted here.

[0061] In an alternative embodiment, step S203 may include the following steps.

[0062] Step S203-1: Based on the historical parameter prediction result, a known parameter sequence arranged in time order is obtained.

[0063] Here, the known parameter sequence can be understood by referring to the related content described above, and a detailed description thereof will be omitted here.

[0064] Step S203-2: Splice the future parameter sequence into the known parameter sequence to obtain a second initial sequence.

[0065] Step S203-3: Obtain a second additional feature based on the real-time task information of the target workplace.

[0066] As described above, the real-time task information may include the product type and product specifications of the wound yarn package product processed in the target workshop. In addition, in an embodiment of the present disclosure, operating parameters used when the process equipment in the target workshop operates can be obtained based on the real-time task information. If the target workshop is a spinning workshop, the process equipment in the target workshop is a spinning box, and the operating parameters used when the spinning box operates may include the specification parameters of the spinneret in the spinning box, the spinning speed, etc. If the target workshop is a winding workshop, the process equipment in the target workshop is a winder, and the operating parameters used when the winder operates may include the brand, specification parameters, winding speed, number of winding heads, etc.

[0067] Based on this, in one example, the real-time task information of the target workplace and the first workplace indicator may both be the second additional feature, or the operating parameters used when the process equipment in the target workplace operates and the first workplace indicator of the target workplace may both be the second additional feature, where the first workplace indicator of the target workplace can be used to determine the processing task type, workplace location, etc. of the target workplace, and the processing task type can include producing a wound yarn package product, winding a wound yarn package product, etc.

[0068] Step S203-4: Construct a second feature sequence based on the second initial sequence and the second additional feature.

[0069] Continuing with the above example, the number of signal generators in the target workplace is K (K≧2 and is an integer), and the known parameter sequence may include K known parameter subsequences that correspond one-to-one to the K signal generators, and the known parameter subsequence corresponding to the i-th signal generator among the K signal generators is {Qi 11 ,Qi 12 ,···,Qi 1n}, and the future parameter subsequence corresponding to the i-th signal generator among the K signal generators may be represented as {Zi 21 ,Zi 22 ,···,Zi 2n}, where 1≦i≦K, and i is a positive integer. When the second additional feature includes the real-time task information of the target workplace and the first workplace mark, the second feature sequence constructed based on the second initial sequence obtained by stitching the future parameter sequence to the known parameter sequence and the second additional feature obtained based on the real-time task information of the target workplace may include feature data as shown in Table 2.

[0070] [Table 2]

[0071] where Y 11 is the time T in the first period 11 This shows the real-time task information of the target workplace at time T 11 Product type Ty of wound yarn package products processed at the target workplace 11 , Product Specifications Sp 11 etc., and Y 12 is the time T in the first period 12This shows the real-time task information of the target workplace at time T 12 Product type Ty of wound yarn package products processed at the target workplace 12 , Product Specifications Sp1 12 etc., and the following may also include Y 1n is the time T in the first period 1n This shows the real-time task information of the target workplace at time T 1n Product type Ty of wound yarn package products processed at the target workplace 1n , Product Specifications Sp 1n etc., Y 21 is the time T in the second period 21 This shows the real-time task information of the target workplace at time T 21 Product type TY of wound yarn package products processed at the target workplace 21 , Product Specifications Sp 21 etc., Y 22 is the time T in the second period 22 This shows the real-time task information of the target workplace at time T 22 Product type Ty of wound yarn package products processed at the target workplace 22 , Product Specifications Sp1 22 etc., and the following may also include Y 2n is the time T in the second period 2n This shows the real-time task information of the target workplace at time T 2n Product type Ty of wound yarn package products processed at the target workplace 2n , Product Specifications Sp 2n etc., where Wid indicates the first workplace mark of the target workplace.

[0072] Thus, in the embodiment of the present disclosure, the second feature sequence not only includes a second initial sequence obtained by splicing an unknown parameter sequence into a known parameter sequence, but also includes a second additional feature obtained based on real-time task information of the target workplace, which can ensure the integrity of the feature data included in the second feature sequence, thereby improving the reliability of the current parameter prediction results.

[0073] Step S204: Using the target time series model, predict the overall control parameters of the multiple signal generators in the second time period according to the first feature sequence and the second feature sequence, and obtain a current parameter prediction result.

[0074] Here, the target time series model may be a trained time series model, such as an Informer model or an Autoregressive Integrated Moving Average Model.

[0075] After obtaining the first feature sequence and the second feature sequence, the first feature sequence and the second feature sequence can be input into the target time series model to obtain the feature processing result output by the target time series model, and the current parameter prediction result can be obtained based on the feature processing result. As mentioned above, the second feature sequence can be obtained based on the second initial sequence and the second additional feature, and the second initial sequence can be obtained by splicing the future parameter sequence into the known parameter sequence. Therefore, after obtaining the feature processing result, the output sequence corresponding to the future parameter sequence in the feature processing result can be the current parameter prediction result.

[0076] Since the second feature sequence is constructed based on the historical parameter prediction results and the future parameter sequence, in the process of using the target time series model to predict the overall control parameters of the multiple signal generators in the second period based on the first feature sequence and the second feature sequence and obtaining the current parameter prediction results, the historical parameter prediction results contained in the second feature sequence play an active guiding role in the feature processing of the target time series model, thereby further improving the reliability of the current parameter prediction results.

[0077] Furthermore, in an embodiment of the present disclosure, the target time series model may have a model structure as shown in Figure 3, that is, the target time series model may include an encoder and a decoder. Based on this, in an optional embodiment, step S204 may include the following steps:

[0078] Step S204-1: Input a first feature sequence into the encoder, and use a feature processing layer in the encoder including a first self-attention module and a distillation module to process the first feature sequence and obtain a first feature mapping result.

[0079] Here, the encoder may include a plurality of feature encoding structures connected in series, and each feature encoding structure may include a first self-attention module and a distillation module connected in series.

[0080] In addition, in the embodiments of the present disclosure, the first self-attention module is used to realize self-attention calculation on input features using the ProbSparse thinning self-attention mechanism to obtain intermediate features, and the intermediate features are input to a distillation module belonging to the same feature coding structure as the first self-attention module, and the distillation module performs distillation processing on the intermediate features to reduce the complexity of the output features, and the distilled intermediate features are used as the output features of the feature coding structure.

[0081] It is understood that in the embodiment of the present disclosure, the output feature of the last feature encoding structure among the plurality of serially connected feature encoding structures is the first feature mapping result.

[0082] Step S204-2: Input the second feature sequence into a second self-attention module in the encoder, and use the second self-attention module to process the second feature sequence and obtain a second feature mapping result.

[0083] Here, the second self-attention module is used to obtain a second feature mapping result by using the ProbSparse thinning self-attention mechanism and the masking mechanism to realize self-attention calculation for the second feature sequence.

[0084] Step S204-3: The first feature mapping result and the second feature mapping result are input to a cross-attention module in the encoder, and the cross-attention module is used to process the first feature mapping result and the second feature mapping result to obtain a feature processing result.

[0085] The feature processing results include current parameter prediction results obtained by predicting the overall control parameters of the plurality of signal generators within the second time period.

[0086] Continuing with the above example, the second feature sequence constructed based on the second initial sequence obtained by splicing the future parameter sequence into the known parameter sequence and the second additional feature obtained according to the real-time task information of the target workplace may include feature data as shown in Table 2. In this case, an output sequence corresponding to the future parameter sequence among the feature processing results is predicted as the overall control parameters of the multiple signal generators in the second time period to obtain a current parameter prediction result. For example, the current parameter prediction result may include K standby parameter subsequences that correspond one-to-one to the K signal generators, and the standby parameter subsequence corresponding to the i-th signal generator among the K signal generators is expressed as {Z'i 21 ,Z'i 22 ,···,Z'i 2n}, where 1≦i≦K and i is a positive integer.

[0087] where, when i=1, Z'1 21 is the time T in the second period 21 , the parameter prediction value of the first signal generator among the K signal generators, specifically, the frequency prediction value F'1 21 , phase predicted value P'1 21 , amplitude prediction value A'1 21 and the direction prediction value D'1 21 Z'1 22 is the time T in the second period 22 , the parameter prediction value of the first signal generator among the K signal generators, specifically, the frequency prediction value F'1 22 , phase predicted value P'1 22 , amplitude prediction value A'1 22 and the direction prediction value D'1 22 Similarly, Z'1 2n is the time T in the second period 2n , the parameter prediction value of the first signal generator among the K signal generators, specifically, the frequency prediction value F'1 2n , phase predicted value P'1 2n , amplitude prediction value A'1 2n and the direction prediction value D'12n may include:

[0088] That is, the current parametric prediction result may include feature data as shown in Table 3.

[0089] [Table 3]

[0090] Based on the above model structure of the target time series model, the current parameter prediction result can be quickly obtained, and the reliability of the current parameter prediction result can be further improved.

[0091] Step S205: Based on the current parameter prediction result, determine one or more target transmitters from the multiple signal transmitters that need to activate within the second period, and obtain parameter prediction values ​​within the second period for each target transmitter.

[0092] The current parameter prediction result can be used to control the operating state of each signal generator within the second time period, so that for each signal generator, it can be determined based on the current parameter prediction result whether the signal generator is a target generator that needs to operate within the second time period, and parameter prediction values ​​within the second time period for each target generator can be obtained, where the parameter prediction values ​​can include a frequency prediction value, a phase prediction value, an amplitude prediction value, and a direction prediction value.

[0093] In one example, for each signal generator, if the frequency prediction value among the parameter prediction values ​​of the signal generator at any time within the second period is 0, the signal generator can be set as an idleable generator that does not need to activate its operation at that time within the second period, while if not, the signal generator can be set as a target generator that needs to activate its operation at that time within the second period. For example, for a first signal generator among the K signal generators, at time T 21 The frequency prediction value F'1 included in the parameter prediction value of the first signal generator in21 is 0, the first signal generator is turned on at time T 21 While the oscillator is an idle oscillator that does not need to be activated at time T 22 The frequency prediction value F'1 included in the parameter prediction value of the first signal generator in 21 is not 0, the first signal generator is turned on at time T 22 and the target transmitter that needs to activate its operation at time T 22 The parameter prediction value of the first signal generator in 22 , phase predicted value P'1 22 , amplitude prediction value A'1 22 and the direction prediction value D'1 22 Includes:

[0094] Step S206: Control each target transmitter to emit a noise interference signal within the second period according to the corresponding parameter prediction value, so as to weaken the second noise signal at the location of the target staff in the target workplace within the second period.

[0095] Here, the second noise signal may be a real-time noise signal that is sensed by the target person within the second period.

[0096] When each target transmitter is controlled to emit a noise interference signal within the second time period according to the corresponding parameter predicted value, the noise interference signal can have a canceling effect on the second noise signal at the target staff's location in the target workplace within the second time period, thereby weakening the second noise signal at the target staff's location in the target workplace within the second time period.

[0097] In an embodiment of the present disclosure, after performing step S201 to obtain a first noise signal of the location of the target staff member in the target workplace within the first period, if the signal strength of the first noise signal is lower than a predetermined strength threshold, steps S201 to S206 are performed, whereas if the signal strength of the first noise signal is equal to or greater than the predetermined strength threshold, the historical parameter prediction result can be used as the current parameter prediction result.

[0098] In the embodiment of the present disclosure, before executing the noise processing method, a target time series model can be obtained by training the time series model as follows.

[0099] A third noise signal of the location of the target staff member in a designated workplace during a third time period is obtained, where the designated workplace is one of a plurality of production workplaces having different functions related to the spinning process, and the target staff member is a worker entering the target workplace.

[0100] Using the time series model, predict the overall control parameters of the multiple signal transmitters arranged in the target workplace within a fourth period based on the third noise signal, and obtain the prediction result of the current training parameters, where the fourth period is a future period of the third period.

[0101] Based on the current training parameter prediction result, one or more preliminary signal generators that need to operate within the fourth period are determined from the multiple signal generators, and training parameter prediction values ​​within the fourth training period of each preliminary signal generator are obtained.

[0102] Each of the preliminary oscillators is controlled to emit a noise interference signal within a fourth time period according to the corresponding training parameter predicted value.

[0103] Optimize model parameters of the time series model based on the difference between the second noise signal and an ideal noise signal at the target staff member's location in the designated workplace within the fourth time period, where the ideal noise signal can be set according to application needs.

[0104] The above content can be understood by referring to the related content, and detailed description will be omitted here.

[0105] In addition, in the embodiment of the present disclosure, if the difference between the second noise signal and the ideal noise signal satisfies a predetermined difference requirement, the latest time series model may be the target time series module.

[0106] In some alternative embodiments, the noise processing method may include, before performing step 102 or step 202:

[0107] The abnormal signal in the first noise signal is removed to obtain a new first noise signal.

[0108] Here, the abnormal signal may be a noise signal other than the noise signal generated during operation of the process equipment in the target workplace, such as a voice signal generated by a worker making a loud noise in the target workplace or a noise signal generated by a worker touching the process equipment.

[0109] Based on this, when step S102 is performed, the overall control parameters of the multiple signal generators in the second time period can be predicted based on the new first noise signal to obtain a current parameter prediction result.When step 202 is performed, a first feature sequence can be constructed based on the new first noise signal and the historical parameter prediction result, so that subsequent steps in the noise processing method can be performed based on the first feature sequence.

[0110] Since the new first noise signal is the first noise signal from which the abnormal signal has been removed, when performing subsequent steps in the noise processing method based on the new first noise signal, interference with the abnormal signal can be avoided, thereby improving the reliability of the current parameter prediction result.

[0111] In one example, "removing the abnormal signal from the first noise signal to obtain a new first noise signal" may be

[0112] performing a wavelet packet transform on the first noise signal to obtain a plurality of initial wavelet packet coefficients;

[0113] performing a threshold process on each initial wavelet packet in the plurality of initial wavelet packet coefficients to obtain a plurality of target wavelet packet coefficients that correspond one-to-one to the plurality of initial wavelet packet coefficients;

[0114] and performing an inverse wavelet packet transform on the plurality of target wavelet packet coefficients to obtain a new first noise signal.

[0115] 4, in one specific example, a wavelet packet kernel constrained convolutional network can be used to perform a wavelet packet transform on a first noise signal to obtain a plurality of initial wavelet packet coefficients. When performing a wavelet packet transform on the first noise signal, a predetermined multi-channel wavelet regularization term can be used as a transform constraint condition of the filter in the wavelet packet kernel constrained convolutional network to decompose the first noise signal to obtain a plurality of initial wavelet packet coefficients. Here, the multi-channel wavelet regularization term can be expressed as follows:

number

[0116] where c denotes the channel of filter h in the wavelet packet kernel constrained convolutional network, C denotes the number of channels of filter h in the wavelet packet kernel constrained convolutional network, and R wave denotes the single-channel wavelet normalization term, p denotes the number of filters h, and u denotes the order of filter h.

[0117] After obtaining a plurality of initial wavelet packet coefficients, an activation network can be used to perform thresholding on each initial wavelet packet in the plurality of initial wavelet packet coefficients to obtain a plurality of target wavelet packet coefficients that correspond one-to-one to the plurality of initial wavelet packet coefficients. For each initial wavelet packet coefficient, a preset soft shrinkage function in the activation network can be used to threshold the initial wavelet packet coefficient to obtain a target wavelet packet coefficient corresponding to the initial wavelet packet coefficient. Here, the soft shrinkage function can be expressed as follows:

number

[0118] where λ denotes a learnable parameter, sigmoid(λ) denotes using the sigmoid function to process λ, σ denotes the standard deviation operation, and x denotes the initial wavelet packet coefficients that need to be thresholded.

[0119] After obtaining a plurality of target wavelet packet coefficients that correspond one-to-one to a plurality of initial wavelet packet coefficients, an inverse wavelet packet transform is performed on the plurality of target wavelet packet coefficients using an inverse wavelet packet kernel constrained convolution network, and a new first noise signal can be obtained by reconstructing the noise signal.

[0120] In this way, in the embodiment of the present disclosure, an improved wavelet packet denoising technique can be used to remove the abnormal signal in the first noise signal to obtain a new first noise signal. The improved wavelet packet denoising technique has an excellent effect on removing the abnormal signal, so that the interference of the abnormal signal can be avoided to the greatest extent possible, thereby further improving the reliability of the current parameter prediction result.

[0121] Furthermore, in the embodiments of the present disclosure, the series-connected wavelet packet core constrained convolution network, activation network, and inverse wavelet packet core constrained convolution network are used as an abnormal signal processing network, and multiple abnormal signal processing networks are connected in series to obtain an abnormal signal processing model. Furthermore, the abnormal signal in the first noise signal is removed using the abnormal signal processing model to obtain a new first noise signal, thereby further improving the reliability of the current parameter prediction results.

[0122] As mentioned above, in the embodiment of the present disclosure, the arrangement of the plurality of signal transmitters in the target workplace is correlated with the real-time noise sound field in the target workplace. Based on this, in an optional embodiment, the noise processing method includes, before performing step S101 or step S201:

[0123] Selecting a plurality of strong noise points in the target workplace where the noise is greatest based on the real-time noise sound field in the target workplace;

[0124] Selecting a plurality of target points at the top of the target work area, the target points corresponding one-to-one to a plurality of strong noise points;

[0125] The method may further include adjusting the arrangement of the plurality of signal transmitters in the target workplace so that the plurality of signal transmitters are arranged at the plurality of target points in one-to-one correspondence with the plurality of target points.

[0126] Here, the real-time noise sound field in the target workplace can be obtained by room acoustic simulation.

[0127] In one example, a workspace model of the target workspace can be obtained by first modeling the target workspace according to the workspace characteristics of the target workspace in acoustic simulation software.

[0128] Here, the acoustic simulation software may be COMSOL multiphysics simulation software, the workplace characteristics may include building characteristics and equipment characteristics of the process equipment, the building characteristics may include building structure, building size, building materials used, etc., and the equipment characteristics may include the number of process equipment installed, layout method, and equipment structure, equipment size, manufacturing materials used, etc. Based on this, in this example, the workplace model may include a building model and an equipment model of the process equipment. Furthermore, in this example, building modeling is performed according to the building characteristics of the target workplace to obtain a building model of the target workplace, and equipment modeling is performed according to the equipment characteristics of the process equipment in the target workplace to obtain an equipment model of the process equipment in the target workplace, and an acoustic simulator can be added to each equipment model.

[0129] Then, first simulation parameters are obtained based on the real-time task information of the target workplace, and the acoustic simulation software controls the acoustic simulators added in each equipment model in the workplace model of the target workplace to emit noise simulation signals according to the first simulation parameters, and further obtains the real-time noise sound field in the target workplace.

[0130] Here, the real-time task information may include the product type, product specifications, etc. of the wound yarn package product processed at the target workplace, and operating parameters to be used when the process equipment at the target workplace operates can be obtained based on the real-time task information. Based on this, in this example, operating parameters to be used when the process equipment at the target workplace operates can be obtained based on the real-time task information of the target workplace, one of the process equipment at the target workplace can be selected as a test equipment, and the startup operation of the test equipment can be controlled based on the operating parameters, and a second pickup installed near the test equipment can be used to collect real-time noise signals generated when the test equipment operates, the real-time noise signals can be analyzed, and first simulation parameters can be obtained to control the acoustic simulator to emit a noise simulation signal that is the same as the real-time noise signal (e.g., the same in frequency, phase, amplitude, and direction). When the process equipment is a spinning box, the operating parameters used when the process equipment is operating may include the specification parameters of the spinneret in the spinning box, the spinning speed, etc. When the process equipment is a winding machine, the operating parameters used when the process equipment is operating may include the brand, specification parameters, winding speed, number of winding heads, etc. The second pickup may be an electromagnetic pickup, a piezoelectric pickup, an optical fiber pickup, a digital pickup, etc.

[0131] After obtaining the real-time noise sound field in the target workplace, a plurality of strong noise points in the target workplace where the noise is the greatest can be selected based on the real-time noise sound field in the target workplace, and a plurality of target points that correspond one-to-one to the plurality of strong noise points at the top of the target workplace can be selected, and the arrangement manner of the plurality of signal transmitters in the target workplace can be adjusted so that the plurality of signal transmitters are arranged at the plurality of target points in one-to-one correspondence with the plurality of target points.

[0132] In one example, a signal transmitter mounting frame is installed on the top of the target workplace, the mounting frame including a plurality of long rails fixed to the top of the target workplace, and a plurality of movable rails for mounting signal transmitters are installed between two adjacent long rails. Here, the movable rails can move on the two long rails corresponding to the movable rails in response to a first movement control command, and the signal transmitters can move on the movable rails corresponding to the signal transmitters in response to a second movement control command. Based on this, a plurality of target points corresponding one-to-one to a plurality of strong noise points on the top of the target workplace can be selected, and then the plurality of signal transmitters can be positioned at the plurality of target points in one-to-one correspondence with the plurality of target points by moving the movable rails and / or the signal transmitters attached to the movable rails.

[0133] 5, for example, based on the real-time noise sound field in the target workspace 501, eight strongest noise points with the largest noise are selected from the target workspace 501, and the eight strongest noise points are respectively strong noise point A1, strong noise point A2, strong noise point A3, strong noise point A4, strong noise point A5, strong noise point A6, strong noise point A7, and strong noise point A8. Then, eight object points corresponding one-to-one to the plurality of strongest noise points can be selected from the top 501-1 of the target workspace 501, and the eight object points are respectively object point A1', object point A2', object point A3', object point A4', object point A5', object point A6', object point A7', and object point A8'.

[0134] Continuing with reference to FIG. 6, after selecting eight target points at the top of the target workplace that correspond one-to-one to the eight strong noise points, the movable rail 601 can be moved and the signal transmitter 602 attached to the movable rail 601 can be moved so that the signal transmitter 602 is positioned at the target point A1'. In a similar manner, the signal transmitter 604 can be positioned at the target point A2', the signal transmitter 606 can be positioned at the target point A3', the signal transmitter 608 can be positioned at the target point A4', the signal transmitter 610 can be positioned at the target point A5', the signal transmitter 612 can be positioned at the target point A6', the signal transmitter 614 can be positioned at the target point A7', and the signal transmitter 616 can be positioned at the target point A8'.

[0135] In the embodiment of the present disclosure, the arrangement manner of the plurality of signal transmitters in the target workplace is automatically adjusted, thereby improving the automation degree of the noise processing method. Meanwhile, since the plurality of target points correspond one-to-one to the plurality of strong noise points in the target workplace where the noise is greatest, after the plurality of signal transmitters are arranged at the plurality of target points in one-to-one correspondence with the plurality of target points, the noise interference signals emitted by each target transmitter in the second period according to the corresponding parameter prediction values ​​can produce a better canceling effect on the second noise signal at the location of the target staff in the target workplace in the second period.

[0136] To better implement the above noise processing method, the embodiments of the present disclosure further provide a noise processing device, which can be applied to an electronic device, which communicates with a plurality of signal transmitters arranged in a target workplace, and the arrangement manner of the plurality of signal transmitters in the target workplace has a corresponding relationship with the real-time noise sound field in the target workplace.
