MODE FOR CARRYING OUT THE INVENTION

[0011] It should be understood that the content described in the section of the summary of the invention does not limit the key points or important features of the embodiments of the present disclosure, nor does it 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 drawings indicate the same or similar members or elements. These drawings are not necessarily drawn to scale. It should be understood that these drawings only show some embodiments provided by the present disclosure and are not regarded as limiting the scope of the present disclosure.

[0013] Hereinafter, the present disclosure will be described in more detail with reference to the drawings. In the drawings, the same reference numerals indicate functionally identical or similar elements. Although various aspects of the embodiments are shown in the drawings, unless otherwise specified, the drawings are not necessarily drawn to scale.

[0014] In addition, for a better explanation of the present disclosure, a number of specific details are described in the following specific embodiments. Those skilled in the art should understand that the present disclosure can be implemented similarly without specific details. In some examples, well-known methods, means, elements, circuits, etc. to those skilled in the art are not described in detail so as to emphasize the gist of the present disclosure.

[0015] As described above, in the industrial environment of the spinning process, the complexity and length of the process flow mean that it is necessary to install a plurality of production workplaces with different functions. Furthermore, a huge number of process facilities are installed in each production workplace, and significant noise pollution occurs when these process facilities operate. For example, in a spinning workplace for producing winding package products, a huge number of spinning boxes, which are process facilities, are installed therein, and significant noise pollution occurs in the spinning workplace when these spinning boxes operate. Also, for example, in a winding workplace for winding winding package products, a huge number of winding machines, which are process facilities, are installed therein, and significant noise pollution occurs in the winding workplace when these winding machines operate.

[0016] In order to reduce noise pollution in the production workplace, an embodiment of the present disclosure provides a noise processing method, which is applied to an electronic device. The electronic device communicates with a plurality of signal transmitters arranged in the target workplace, and the arrangement mode of the plurality of signal transmitters in the target workplace is correlated with the real-time noise sound field in the target workplace. Here, the target workplace may be any one of a plurality of production workplaces with different functions related to the spinning process, and the signal transmitter may be a speaker.

[0017] In addition, in the embodiments of the present disclosure, the main types of the wound package products may include at least one of Partially Oriented Yarns (POY), Fully Drawn Yarns (FDY), Draw Textured Yarns (DTY) (or low-elasticity yarns, etc.). For example, the types of the wound package products may specifically include Polyester Partially Oriented Yarns, Polyester Fully Drawn Yarns, Polyester Drawn Yarns, Polyester Draw Textured Yarns, etc.

[0018] FIG. 1 is a schematic flowchart 1 of the noise processing method according to the embodiments of the present disclosure. Hereinafter, the noise processing method according to the embodiments of the present disclosure will be described with reference to FIG. 1. Although a logical order is shown in the schematic flowchart, in some cases, the steps shown or described may be executed in other orders.

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

[0020] Here, the first period may be the current period with a first predetermined time length as the time length. In one example, the first predetermined time length is determined according to the moving speed of the target staff. For example, the first predetermined time length may show a negative correlation with the moving speed of the target staff, that is, the faster the moving speed of the target staff, the shorter the first predetermined time length, and the slower the moving speed of the target staff, the longer the first predetermined time length.

[0021] In addition, in the embodiments of the present disclosure, the target staff 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 within the first period. In one example, the first noise signal is collected by a first pickup device worn by the target staff and transmitted to an electronic device. The first pickup device may be an electromagnetic pickup device, a piezoelectric pickup device, an optical fiber pickup device, a digital pickup device, or the like.

[0022] Step S102: Based on the first noise signal, predict the overall control parameters of a plurality of signal transmitters within the second period, and obtain the current parameter prediction result.

[0023] The second period is a future period of the first period. For example, the second period may be a future period of the first period with a time length of a second predetermined time length. In the embodiments of the present disclosure, the second predetermined time length may be the same as the first predetermined time length or different from the first predetermined time length. In one example, the second predetermined time length is determined according to the moving speed of the target staff. For example, the second predetermined time length may show a negative correlation with the moving speed of the target staff, that is, the faster the moving speed of the target staff, the shorter the second predetermined time length, and the slower the moving speed of the target staff, the longer the second predetermined time length.

[0024] It should be noted that in the embodiments of the present disclosure, the current parameter prediction result is used to control the operating state of each signal transmitter 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 plurality of signal transmitters, and obtain the parameter prediction values of each target transmitter within the second period.

[0026] Since the current parameter prediction results are used to control the operating states of the signal transmitters within the second period, for each signal transmitter, it is possible to determine whether the signal transmitter is a target transmitter that needs to operate within the second period based on the current parameter prediction results, and obtain the parameter prediction values of each target transmitter within the second period. Here, 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: In order to weaken the second noise signal of the location of the target staff in the target workplace within the second period, control each target transmitter to transmit a noise interference signal within the second period according to the corresponding parameter prediction value.

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

[0029] After controlling each target transmitter to transmit a noise interference signal within the second period according to the corresponding parameter prediction value, the noise interference signal can generate a canceling effect on the second noise signal of the location of the target staff in the target workplace within the second period, thereby weakening the second noise signal of the location of the target staff in the target workplace within the second period.

[0030] According to the invention of the present disclosure, after obtaining the first noise signal of the location of the target staff in the target workplace within the first period, based on the first noise signal, the overall control parameters of a plurality of signal transmitters within the second period (a future period of the first period) can be predicted, and the current parameter prediction result can be obtained. The current parameter prediction result is obtained by prediction based on the first noise signal, and is aimed at establishing a strong correlation with the second period, and is not obtained by directly analyzing the first noise signal. Therefore, based on the current parameter prediction result, one or more target transmitters that need to start operating within the second period are determined from a plurality of signal transmitters, and after obtaining the parameter prediction values of each target transmitter within the second period, by controlling each target transmitter, the noise interference signal transmitted in the second period according to the corresponding parameter prediction value can produce a good cancellation effect on the second noise signal of the location of the target staff in the target workplace within the second period, thereby weakening the second noise signal of the location of the target staff in the target workplace within the second period, and thereby reducing the noise pollution in the target workplace.

[0031] Figure 2 is a schematic flowchart 2 of the noise processing method according to an embodiment of the present disclosure. Hereinafter, the noise processing method according to an embodiment of the present disclosure will be described with reference to Figure 2. Although a logical order is shown in the schematic flowchart, in some cases, the steps shown or described may be executed in other orders.

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

[0033] The first period may be the current period with a time length of the first predetermined time length. In one example, the first predetermined time length is determined according to the moving speed of the target staff. For example, the first predetermined time length may show a negative correlation with the moving speed of the target staff, that is, the faster the moving speed of the target staff, the shorter the first predetermined time length, and the slower the moving speed of the target staff, the longer the first predetermined time length.

[0034] In addition, in the embodiments of the present disclosure, the target staff 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 within the first period. In one example, the first noise signal is collected by a first pickup worn by the target staff and transmitted to an electronic device. Here, the first pickup may be an electromagnetic pickup, a piezoelectric pickup, an optical fiber 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 obtained by predicting the overall control parameters of a plurality of signal transmitters within the first period based on the zeroth noise signal of the location of the target staff in the target workplace within the zeroth period, and the zeroth period is the historical period of the first period. For example, the zeroth period may be the historical period of the first period with a time length of a third predetermined time length. In the embodiments of the present disclosure, the third predetermined time length may be the same as the first predetermined time length or different from the first predetermined time length. In one example, the third predetermined time length is determined according to the moving speed of the target staff. For example, the third predetermined time length may show a negative correlation with the moving speed of the target staff, that is, the faster the moving speed of the target staff, the shorter the third predetermined time length, and the slower the moving speed of the target staff, the longer the third predetermined time length.

[0037] In addition, in the embodiments of the present disclosure, the historical parameter prediction result is used to control the operating state of each signal transmitter within the first period. More specifically, for each signal transmitter, the historical transmission parameter of the signal transmitter within the first period is obtained based on the historical parameter prediction result.

[0038] The historical transmission parameter 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: Based on the first noise signal, obtain a sequence of noise signals arranged in chronological order.

[0041] In one example, the sequence of noise signals arranged in chronological order obtained based on the first noise signal may be represented as {X 11 , X 12 , ···, X 1n}. Here, X 11 represents the noise data of the location of the target staff in the target workplace at time T 11 within the first period. Specifically, it may include a frequency value F 11 , a phase value P 11 , an amplitude value A 11 and a direction value D 11 . X 12 represents the noise data of the location of the target staff in the target workplace at time T 12 within the first period. Specifically, it may include a frequency value F 12 , a phase value P 12 , an amplitude value A 12 and a direction value D 12 . Similarly, hereinafter, X 1n represents the noise data of the location of the target staff in the target workplace at time T 1n within the first period. Specifically, it may include a frequency value F 1n , a phase value P 1n , an amplitude value A 1n and a direction value D 1n .

[0042] Step S202-2: Based on the historical parameter prediction result, obtain a sequence of known parameters arranged in chronological order.

[0043] In one example, the number of signal transmitters in the target workplace is K (where K ≥ 2 and K is an integer), and the known parameter sequence may include K known parameter subsequences that correspond one-to-one with the K signal transmitters. Moreover, the known parameter subsequence corresponding to the i-th signal transmitter among the K signal transmitters may be represented as {Qi 11 , Qi 12 , ···, Qi 1n}, where 1 ≤ i ≤ K and i is a positive integer.

[0044] Here, when i = 1, Q1 11 represents the predicted value of the historical parameters of the first signal transmitter among the K signal transmitters at time T 11 during the first period. Specifically, it may include the predicted frequency value F1 11 , the predicted phase value P1 11 , the predicted amplitude value A1 11 and the predicted direction value D1 11 . Q1 12 represents the predicted value of the historical parameters of the first signal transmitter among the K signal transmitters at time T 12 during the first period. Specifically, it may include the predicted frequency value F1 12 , the predicted phase value P1 12 , the predicted amplitude value A1 12 and the predicted direction value D1 12 . Similarly, hereinafter, Q1 1n represents the predicted value of the historical parameters of the first signal transmitter among the K signal transmitters at time T 1n during the first period. Specifically, it may include the predicted frequency value F1 1n , the predicted phase value P1 1n , the predicted amplitude value A1 1n and the predicted direction value D1 1n .

[0045] When the value of i is other than 1, for Qi 11 , Qi 12 , ···, Qi 1n , reference may be made to the relevant content above for understanding, and detailed description is omitted here.

[0046] Step S202-3: Splice the known parameter sequence to 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 winding package product processed at the target workplace. Also, in the embodiments of the present disclosure, based on the real-time task information, the operating parameters used when the process equipment at the target workplace operates can be obtained. When the target workplace is a spinning workplace, the process equipment at the target workplace is a spinning box, and the operating parameters used when the spinning box operates may include the specification parameters of the spinneret, the spinning speed, etc. When the target workplace is a winding workplace, the process equipment at the target workplace is a winder, and the operating parameters used when the winder operates may include the brand of the winder, the specification parameters, the winding speed, the number of winding heads, etc.

[0049] Based on this, in one example, both the real-time task information of the target workplace and the first workplace identifier can be used as the first additional feature, or both the operating parameters used when the process equipment at the target workplace operates and the first workplace identifier of the target workplace can be used as the first additional feature. Here, the first workplace identifier 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 the production of winding package products, the winding of winding package products, 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 above example, the noise signal sequence is {X 11 ,X 12 ,···,X 1n} may be represented as, the number of signal transmitters in the target factory is K (K≥2 and is an integer), the known parameter sequence may include K known parameter subsequences that correspond one-to-one with the K signal transmitters, and the known parameter subsequence corresponding to the i-th signal transmitter among the K signal transmitters is {Qi 11 , Qi 12 , ···, Qi 1n}, where 1≤i≤K and i is a positive integer. When the first additional feature includes the real-time task information of the target workplace and the first workshop identifier, 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] Here, Y 11 represents the real-time task information of the target workplace at time T 11 within the first period. Specifically, at time T 11 within the first period, it may include the product type Ty 11 of the winding package product processed in the target workplace, the product specification Sp 11 , etc. Y 12 represents the real-time task information of the target workplace at the time within the first period. Specifically, at time T 12 within the first period, it may include the product type Ty 12 of the winding package product processed in the target workplace, the product specification Sp1 12 , etc. Similarly, hereinafter, Y 1n represents the real-time task information of the target workplace at time T 1n within the first period. Specifically, at time T 1n within the first period, it may include the product type Ty 1n, Product Specification Sp 1n etc. may be included, and Wid indicates the first workplace sign of the target workplace.

[0054] Thus, in the embodiments of the present disclosure, in addition to including the first initial sequence obtained by splicing the known parameter sequence into the noise signal sequence, the first feature sequence can also include the first additional feature obtained based on the real-time task information of the target workplace. Therefore, the integrity of the feature data included in the first feature sequence can be guaranteed, thereby enhancing the reliability of the current parameter prediction result.

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

[0056] Among them, for the prediction result of the historical parameter, it can be understood by referring to the relevant content, and detailed description is omitted here.

[0057] In addition, in the embodiments of the present disclosure, the future parameter sequence is the 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 transmitters 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 with K signal transmitters. Among them, the future parameter subsequence corresponding to the i-th signal transmitter among the K signal transmitters may be represented as {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 within the second period21 indicates a data element corresponding to a predicted parameter value of the first signal transmitter among the K signal transmitters, specifically, a predicted frequency value F1 21 the data element corresponding to, the predicted phase value P1 21 the data element corresponding to, the predicted amplitude value A1 21 the data element corresponding to and the predicted direction value D1 21 may include the data element corresponding to, and the values of these four may be any set values, for example, 0, and also, Z1 22 is the time T within the second period 22 indicates a data element corresponding to a predicted parameter value of the first signal transmitter among the K signal transmitters, specifically, a predicted frequency value F1 22 the data element corresponding to, the predicted phase value P1 22 the data element corresponding to, the predicted amplitude value A1 22 the data element corresponding to and the predicted direction value D1 22 may include the data element corresponding to, and the values of these four may be any set values, for example, 0, and similarly hereinafter, Z1 2n is the time T within the second period 2n indicates a data element corresponding to a predicted parameter value of the first signal transmitter among the K signal transmitters, specifically, a predicted frequency value F1 2n the data element corresponding to, the predicted phase value P1 2n the data element corresponding to, the predicted amplitude value A1 2n the data element corresponding to and the predicted direction value D1 2n may include the data element corresponding to.

[0060] When the value of i is other values, Zi 21 , Zi 22 , ···, Zi 2n can be understood by referring to the relevant content above, and detailed description is omitted here.

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

[0062] Step S203-1: Based on the historical parameter prediction results, obtain a known parameter sequence arranged in chronological order.

[0063] Here, for the known parameter sequence, it can be understood by referring to the foregoing related content, and detailed description is 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: Based on the real-time task information of the target workplace, obtain a second additional feature.

[0066] As described above, the real-time task information may include the product type, product specifications, etc. of the winding package products processed in the target workplace. Also, in the embodiments of the present disclosure, based on the real-time task information, the operating parameters used when the process equipment in the target workplace operates can be obtained. When the target workplace is a spinning workplace, the process equipment in the target workplace is a spinning box, and the operating parameters used when the spinning box operates may include the specification parameters of the spinneret, spinning speed, etc. in the spinning box. Also, when the target workplace is a winding workplace, the process equipment in the target workplace 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. of the winding machine.

[0067] Based on this, in one example, the real-time task information of the target workplace and the first workplace identifier may be used together as the second additional feature, or the operating parameters used when the process equipment in the target workplace operates and the first workplace identifier of the target workplace may be used together as the second additional feature. Here, the first workplace identifier 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 the production of winding package products, the winding of winding package products, etc.

[0068] Step S203-4: Based on the second initial sequence and the second additional feature, construct a second feature sequence.

[0069] Continuing with the above example, the number of signal transmitters 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 with the K signal transmitters. Moreover, the known parameter subsequence corresponding to the i-th signal transmitter among the K signal transmitters may be represented as {Qi 11 , Qi 12 , ···, Qi 1n}, and the future parameter subsequence corresponding to the i-th signal transmitter among the K signal transmitters 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 identifier, 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] Here, Y 11 represents the real-time task information of the target workplace at time T 11 during the first period. Specifically, it may include the product type Ty 11 of the winding package product processed at the target workplace at time T 11 during the first period, the product specification Sp 11 , etc. Also, Y 12 represents the real-time task information of the target workplace at time T 12shows the real-time task information of the target workplace, specifically the time T within the first period 12 shows the product type Ty of the wound package product processed at the target workplace at 12 , product specification Sp1 12 and so on may be included. Similarly hereinafter, Y 1n is the real-time task information of the target workplace at the time T within the first period, specifically the time T within the first period 1n shows the real-time task information of the target workplace at 1n shows the product type Ty of the wound package product processed at the target workplace at 1n , product specification Sp 1n and so on may be included. Y 21 is the time T within the second period 21 shows the real-time task information of the target workplace at the time T within the second period, specifically the time T within the second period 21 shows the product type TY of the wound package product processed at the target workplace at 21 , product specification Sp 21 and so on may be included. Y 22 is the time T within the second period 22 shows the real-time task information of the target workplace at the time T within the second period, specifically the time T within the second period 22 shows the product type Ty of the wound package product processed at the target workplace at 22 , product specification Sp1 22 and so on may be included. Similarly hereinafter, Y 2n is the time T within the second period 2n shows the real-time task information of the target workplace at the time T within the second period, specifically the time T within the second period 2n shows the product type Ty of the wound package product processed at the target workplace at 2n , product specification Sp 2n and so on may be included. Wid indicates the first workplace identifier of the target workplace.

[0072] Thus, in the embodiments of the present disclosure, in addition to the second feature sequence including the second initial sequence obtained by splicing the unknown parameter sequence to the known parameter sequence, the second feature sequence can also include the second additional features obtained based on the real-time task information of the target workplace, and the integrity of the feature data included in the second feature sequence can be guaranteed, thereby improving the reliability of the current parameter prediction result.

[0073] Step S204: Using the target time series model, based on the first feature sequence and the second feature sequence, predict the overall control parameters of a plurality of signal transmitters within the second period, and obtain the current parameter prediction result.

[0074] Here, the target time series model may be a trained time series model, for example, an Informer model, an Autoregressive Integrated Moving Average Model, etc.

[0075] After obtaining the first feature sequence and the second feature sequence, input the first feature sequence and the second feature sequence into the target time series model, obtain the feature processing result output by the target time series model, and based on the feature processing result, the current parameter prediction result can be obtained. As described above, the second feature sequence may be obtained based on the second initial sequence and the second additional features, and the second initial sequence may be obtained by splicing the future parameter sequence to 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 used as 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, when using the target time series model to predict the overall control parameters of a plurality of signal transmitters within the second period and obtain the current parameter prediction results based on the first feature sequence and the second feature sequence, the historical parameter prediction results included 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 the embodiments of the present disclosure, the target time series model may have a model structure as shown in FIG. 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 the first feature sequence into the encoder, and process the first feature sequence by using a feature processing layer including a first self-attention module and a distillation module in the encoder to 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] Also, in the embodiments of the present disclosure, the first self-attention module is used to implement self-attention calculation on the input features by using the ProbSparse subsampling self-attention mechanism to obtain intermediate features, and the intermediate features are input into a distillation module belonging to the same feature encoding structure as the first self-attention module, and the distillation module performs distillation processing on the intermediate features, thereby reducing the complexity of the output features and using the distilled intermediate features as the output features of the feature encoding structure.

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

[0082] Step S204-2: Input the second feature sequence into the second self-attention module in the encoder, 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 the second feature mapping result by realizing self-attention calculation on the second feature sequence by using a ProbSparse subsampling self-attention mechanism and a masking mechanism.

[0084] Step S204-3: Input the first feature mapping result and the second feature mapping result into the cross-attention module in the encoder, use the cross-attention module to process the first feature mapping result and the second feature mapping result, and obtain a feature processing result.

[0085] The feature processing result includes the current parameter prediction result obtained by predicting the overall control parameters of a plurality of signal transmitters within the second period.

[0086] Continuing with the foregoing 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 parameter of a plurality of signal transmitters within the second period, and the current parameter prediction result is obtained. For example, the current parameter prediction result may include K standby parameter subsequences corresponding one-to-one to the K signal transmitters, and the standby parameter subsequence corresponding to the i-th signal transmitter among the K signal transmitters is {Z'i 21 , Z'i 22 , ···, Z'i 2n}, where 1 ≤ i ≤ K and i is a positive integer.

[0087] Here, when i = 1, Z'1 21 represents the parameter prediction value of the first signal transmitter among the K signal transmitters at time T 21 within the second period, specifically including the frequency prediction value F'1 21 , the phase prediction value P'1 21 , the amplitude prediction value A'1 21 and the direction prediction value D'1 21 . Z'1 22 represents the parameter prediction value of the first signal transmitter among the K signal transmitters at time T 22 within the second period, specifically including the frequency prediction value F'1 22 , the phase prediction value P'1 22 , the amplitude prediction value A'1 22 and the direction prediction value D'1 22 . Similarly hereinafter, Z'1 2n represents the parameter prediction value of the first signal transmitter among the K signal transmitters at time T 2n within the second period, specifically including the frequency prediction value F'1 2n , the phase prediction value P'1 2n , the 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 that need to start operations within the second period from a plurality of signal transmitters, and obtain the parameter prediction values of each target transmitter within the second period.

[0092] Since the current parameter prediction result can be used to control the operating state of each signal transmitter within the second period, for each signal transmitter, based on the current parameter prediction result, it can be determined whether the signal transmitter is a target transmitter that needs to operate during the second period, and the parameter prediction values of each target transmitter within the second period can be obtained. Here, the parameter prediction values can include frequency prediction values, phase prediction values, amplitude prediction values, and direction prediction values.

[0093] In one example, for each signal transmitter, if the frequency prediction value among the parameter prediction values of the signal transmitter at any time within the second period is 0, the signal transmitter is set as an idle-capable transmitter that does not need to start operations at that time within the second period, while if not, the signal transmitter can be set as a target transmitter that needs to start operations at that time within the second period. For example, for the first signal transmitter among K signal transmitters, the frequency prediction value F'1 included in the parameter prediction value of the first signal transmitter at time T within the second period 21 in the second period.21 When it is 0, the first signal transmitter is an idle-capable transmitter that does not need to be activated at time T within the second period. On the other hand, for example, the predicted frequency value F'1 included in the predicted parameter value of the first signal transmitter at time T within the second period 21 When it is not 0, the first signal transmitter can be a target transmitter that needs to be activated at time T within the second period, and the predicted parameter value of the first signal transmitter at time T within the second period 22 The predicted frequency value F'1 included in the predicted parameter value of the first signal transmitter at time T 21 When it is not 0, the first signal transmitter can be a target transmitter that needs to be activated at time T within the second period 22 And the predicted parameter value of the first signal transmitter at time T within the second period 22 The predicted parameter value of the first signal transmitter at time T includes the predicted frequency value F'1 22 The predicted phase value P'1 22 The predicted amplitude value A'1 22 And the predicted direction value D'1 22 And includes.

[0094] Step S206: In order to weaken the second noise signal of the location of the target staff in the target workplace within the second period, each target transmitter is controlled to transmit a noise interference signal within the second period according to the corresponding predicted parameter value.

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

[0096] When each target transmitter is controlled to transmit a noise interference signal within the second period according to the corresponding predicted parameter value, the noise interference signal can generate a canceling effect on the second noise signal of the location of the target staff in the target workplace within the second period, thereby weakening the second noise signal of the location of the target staff in the target workplace within the second period.

[0097] In addition, in the embodiments of the present disclosure, after obtaining the first noise signal of the location of the target staff in the target workplace within the first period by executing step S201, when the signal intensity of the first noise signal is lower than a predetermined intensity threshold, steps S201 to S206 are executed. On the other hand, when the signal intensity of the first noise signal is equal to or higher than the predetermined intensity threshold, the historical parameter prediction result can be directly used as the current parameter prediction result.

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

[0099] Obtain the third noise signal of the location of the target staff in the designated workplace within the third period. Here, the designated workplace is any one of a plurality of production workplaces with different functions related to the spinning process, and the target staff is a worker entering the target workplace.

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

[0101] Based on the current training parameter prediction result, determine one or more preselected transmitters that need to operate within the fourth period from the plurality of signal transmitters, and obtain the training parameter prediction values of each preselected transmitter within the fourth training period.

[0102] Control each preselected transmitter to transmit a noise interference signal within the fourth period according to the corresponding training parameter prediction value.

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

[0104] Regarding the above content, it can be understood by referring to the relevant content, and detailed description is omitted here.

[0105] In addition, in the embodiments of the present disclosure, when the difference between the second noise signal and the ideal noise signal meets the predetermined difference requirement, the latest time series model may be used as the target time series module.

[0106] In some alternative embodiments, the noise processing method may include the following before executing step 102 or step 202.

[0107] Remove the abnormal signal in the first noise signal and obtain a new first noise signal.

[0108] Here, the abnormal signal may be other noise signals other than the noise signals generated during the operation of the process equipment in the target workplace. For example, it may be a voice signal generated by an operator shouting loudly in the target workplace or a noise signal generated by an operator touching the process equipment.

[0109] Based on this, when executing step S102, based on the new first noise signal, the overall control parameters of a plurality of signal transmitters during the second period can be predicted, and the current parameter prediction result can be obtained. When executing step 202, by constructing the first feature sequence based on the new first noise signal and the historical parameter prediction result, the subsequent steps in the noise processing method can be executed based on the first feature sequence.

[0110] Since the new first noise signal is obtained by removing the abnormal signal in the first noise signal, when subsequent steps in the noise processing method are executed based on the new first noise signal, the interference of the abnormal signal can be avoided, thereby improving the reliability of the current parameter prediction result.

[0111] In one example, "obtaining a new first noise signal by removing the abnormal signal in the first noise signal" may involve

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

[0113] performing threshold processing on each initial wavelet packet in the plurality of initial wavelet packet coefficients to obtain a plurality of target wavelet packet coefficients corresponding one-to-one to the plurality of initial wavelet packet coefficients,

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

[0115] Referring to FIG. 4, in one specific example, by using a wavelet packet kernel constrained convolution network, wavelet packet transform can be performed on the first noise signal to obtain a plurality of initial wavelet packet coefficients. When performing wavelet packet transform on the first noise signal, a preset multi-channel wavelet regularization term can be used as the conversion constraint condition of the filter in the wavelet packet kernel constrained convolution network to decompose the first noise signal and obtain a plurality of initial wavelet packet coefficients. Here, the multi-channel wavelet regularization term can be expressed as follows.

Equation

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

[0117] After obtaining a plurality of initial wavelet packet coefficients, by using an activation network, threshold processing is performed on each initial wavelet packet among the plurality of initial wavelet packet coefficients, and a plurality of target wavelet packet coefficients corresponding one-to-one to the plurality of initial wavelet packet coefficients can be obtained. For each initial wavelet packet coefficient, threshold processing is performed on the initial wavelet packet coefficient by a preset soft shrinkage function in the activation network, and a target wavelet packet coefficient corresponding to the initial wavelet packet coefficient can be obtained. Here, the soft shrinkage function can be expressed as follows:

Equation

[0118] Here, λ represents a learnable parameter, sigmoid(λ) represents processing λ using the sigmoid function, σ represents a standard deviation operation, and x represents the initial wavelet packet coefficient that needs to be subjected to threshold processing.

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

[0120] Thus, in the embodiments of the present disclosure, by using the improved wavelet packet noise removal technology, abnormal signals in the first noise signal can be removed, and a new first noise signal can be obtained. Since the improved wavelet packet noise removal technology has an excellent removal effect on abnormal signals, the interference of abnormal signals can be avoided to the greatest extent, thereby further improving the reliability of the current parameter prediction result.

[0121] Furthermore, in the embodiments of the present disclosure, a wavelet packet core-constrained convolutional network, an activation network, and an inverse wavelet packet core-constrained convolutional network connected in series are used as one abnormal signal processing network, and a plurality of abnormal signal processing networks are connected in series to obtain an abnormal signal processing model. Then, by removing the abnormal signals in the first noise signal with the abnormal signal processing model and obtaining a new first noise signal, the reliability of the current parameter prediction result can be further improved.

[0122] As described above, in the embodiments of the present disclosure, the arrangement method of a 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 is to, before executing step S101 or step S201,

[0123] select a plurality of strong noise points with the maximum noise in the target workplace based on the real-time noise sound field in the target workplace,

[0124] select a plurality of target points corresponding one-to-one to the plurality of strong noise points at the top of the target workplace,

[0125] and further include adjusting the arrangement method 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 a 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 means of indoor acoustic simulation.

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

[0128] Here, the acoustic simulation software may be COMSOL Multiphysics simulation software, the workplace characteristics may include building characteristics and equipment characteristics of 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. of the process equipment. Based on this, in this example, the workplace model may include a building model and an equipment model of the process equipment. Further, in this example, according to the building characteristics of the target workplace, building modeling is performed to obtain a building model of the target workplace, 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 in the workplace model of the target workplace with the acoustic simulation software.

[0129] Thereafter, based on the real-time task information of the target workplace, first simulation parameters are obtained, the acoustic simulators added to each equipment model in the workplace model of the target workplace are controlled with the acoustic simulation software, a noise simulation signal is transmitted according to the first simulation parameters, and further, the real-time noise sound field in the target workplace is obtained.

[0130] Here, the real-time task information may include the product type, product specifications, etc. of the winding package products processed at the target workplace, and it is possible to obtain the operating parameters used when the process equipment at the target workplace operates based on the real-time task information. Based on this, in this example, based on the real-time task information of the target workplace, the operating parameters used when the process equipment at the target workplace operates are obtained, any process equipment at the target workplace is selected as the test equipment, and based on the operating parameters, the startup operation of the test equipment is controlled, and the real-time noise signal generated when the test equipment operates is collected using a second pickup installed near the test equipment, the real-time noise signal is analyzed, the first simulation parameters are obtained, and the acoustic simulator is controlled to transmit a noise simulation signal that is the same as the real-time noise signal (for example, the same in terms of frequency value, phase value, amplitude value, and direction value). When the process equipment is a spinning box, the operating parameters used when the process equipment operates may include the specification parameters of the spinneret in the spinning box, the spinning speed, etc. When the process equipment is a winder, the operating parameters used when the process equipment operates may include the brand of the winder, specification parameters, winding speed, the 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, based on the real-time noise sound field in the target workplace, a plurality of strong noise points with the maximum noise in the target workplace are selected, and further a plurality of target points corresponding one-to-one to the plurality of strong noise points at the top of the target workplace are selected, and the arrangement method of a 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 a one-to-one correspondence.

[0132] In one example, an attachment frame for a signal transmitter is installed at the top of the target workplace. The attachment frame includes a plurality of long rails fixed to the top of the target workplace, and a plurality of movable rails for attaching the signal transmitter are installed between two adjacent long rails. Here, the movable rail can move on two long rails corresponding to the movable rail in response to a first movement control command, and the signal transmitter can move on the movable rail corresponding to the signal transmitter in response to a second movement control command. Based on this, after selecting a plurality of target points that correspond one-to-one with a plurality of strong noise points at the top of the target workplace, by moving the movable rail and / or the signal transmitter attached to the movable rail, a plurality of signal transmitters can be arranged at the plurality of target points in a one-to-one correspondence with the plurality of target points.

[0133] Referring to FIG. 5, exemplarily, based on the real-time noise sound field in the target workplace 501, eight strong noise points with the maximum noise are selected from the target workplace 501. The eight strong noise points are 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, respectively. Then, eight target points that correspond one-to-one with the plurality of strong noise points can be selected from the top 501-1 of the target workplace 501. The eight target points are target point A1', target point A2', target point A3', target point A4', target point A5', target point A6', target point A7', and target point A8', respectively.

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

[0135] In the embodiments of the present disclosure, since the arrangement method of a plurality of signal transmitters in the target workplace is automatically adjusted, the degree of automation of the noise processing method can be improved. On the other hand, since the plurality of target points correspond one-to-one to a plurality of strong noise points where the noise in the target workplace is the largest, after arranging the plurality of signal transmitters corresponding one-to-one to the plurality of target points at the plurality of target points, the noise interference signals transmitted by each target transmitter within the second period according to the predicted parameter values corresponding thereto can generate a better cancellation effect on the second noise signal of the location of the target staff in the target workplace within the second period.

[0136] In order 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. The electronic device communicates with a plurality of signal transmitters arranged in the target workplace, and the arrangement method 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.
