However, in the heating and foaming process of plastic foam materials, determining the stop time of plastic foam heating is a challenging technical problem.

[0022] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0023] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in the present invention include direct and indirect connections (couplings) unless otherwise specified.

[0024] In an embodiment of the present invention, there is provided Figure 1 A control method for plastic foam processing is shown, and the control method for plastic foam processing includes steps S1 to S5:

[0025] Step S1, obtaining a heating video of the plastic foam in the starting time period of the foaming machine.

[0026] For example, the plastic foam material may be a polypropylene plastic foam material.

[0027] The heating video of the plastic foam in the starting time period of the foaming machine can be captured by a high-definition camera arranged on the foaming machine. A high-definition camera can be installed and located on the top of the foaming machine. In the starting time period, the camera is started to record the heating process of the plastic foam. The heating video of the plastic foam in the starting time period of the foaming machine includes information such as the formation, color change, and expansion of the plastic foam.

[0028] The start time period is a preset time period. As an example, the start time period can be one of the first minute, first three minutes, first five minutes, and first ten minutes before the plastic foam starts to be heated in the foaming machine.

[0029] Step S2, based on the heating video of the plastic foam in the starting time period of the foaming machine, use the heating information processing model to determine the color change sequence data of the plastic foam in the starting time period, the expansion degree change sequence data of the plastic foam in the starting time period, and the surface smoothness change sequence data of the plastic foam in the starting time period.

[0030] The heating information processing model is a gated loop unit. The input of the heating information processing model is the heating video of the plastic foam in the starting time period of the foaming machine, and the output of the heating information processing model is the color change sequence data of the plastic foam in the starting time period, the expansion degree change sequence data of the plastic foam in the starting time period, and the surface smoothness change sequence data of the plastic foam in the starting time period.

[0031] The color change sequence data is a data sequence that records the color change of the plastic foam in the initial time period. The color change sequence data can be used to analyze the color characteristic changes of the plastic foam during the heating process.

[0032] The expansion degree change sequence data is a data sequence that records the expansion degree change of the plastic foam within the initial time period. The expansion degree change sequence data can be used to analyze the change of the expansion characteristics of the plastic foam.

[0033] The surface smoothness change sequence data is a data sequence that records the surface smoothness change of the plastic foam in the initial time period. The surface smoothness change sequence data can be used to analyze the change in the surface smoothness characteristics of the plastic foam.

[0034] The Gated Recurrent Unit (GRU) is used to process sequence data and time series information. The Gated Recurrent Unit consists of three components: a memory unit, an update gate, and a reset gate. The process of heating plastic foam in a foaming machine is a dynamic process that requires consideration of the impact of information from past time points on the current state. The Gated Recurrent Unit can better capture long-term dependencies in sequence data through a gating mechanism, thereby more accurately determining the sequence data of changes in plastic foam at the beginning of the time period.

[0035] In some embodiments, the heating information processing model includes a segmentation time point determination layer, a video segmentation layer, and a data determination layer. The segmentation time point determination layer, the video segmentation layer, and the data determination layer all include a gated loop unit. The input of the segmentation time point determination layer is the heating video of the plastic foam in the starting time period of the foaming machine, and the output of the segmentation time point determination layer is a plurality of segmentation time points. The input of the video segmentation layer is the heating video of the plastic foam in the starting time period of the foaming machine and the plurality of segmentation time points. The output of the video segmentation layer is a plurality of heating video clips of the plastic foam in the starting time period of the foaming machine. The input of the data determination layer is a plurality of heating video clips of the plastic foam in the starting time period of the foaming machine. The output of the data determination layer is the color change sequence data of the plastic foam in the starting time period, the expansion degree change sequence data of the plastic foam in the starting time period, and the surface smoothness change sequence data of the plastic foam in the starting time period.

[0036] By dividing the model into different layers, each layer can focus on performing a specific task. For example, the segmentation time point determination layer focuses on identifying key time points in the video, the video segmentation layer is responsible for segmenting the video based on these time points, and the data determination layer extracts feature data such as color, dilation, and surface smoothness. This modular approach allows each layer to be optimized specifically for its task, improving the efficiency and performance of the overall model.

[0037] Breaking down the task into multiple steps, each of which builds on the previous step, can gradually refine and refine information. This approach helps improve the accuracy of the final output data because each layer can focus on improving the accuracy of its specific task, thereby improving the reliability of the entire model.

[0038] Step S3, based on the heating video of the plastic foam in the starting time period of the foaming machine, the color change sequence data of the plastic foam in the starting time period, the expansion degree change sequence data of the plastic foam in the starting time period, and the surface smoothness change sequence data of the plastic foam in the starting time period, a predicted video segment of the subsequent heating process of the plastic foam is determined using a variational autoencoder.

[0039] The predicted video clip of the subsequent heating process of the plastic foam is a video clip of the subsequent heating process of the plastic foam predicted by the variational autoencoder output.

[0040] The input of the variational autoencoder is the heating video of the plastic foam in the starting time period of the foaming machine, the color change sequence data of the plastic foam in the starting time period, the expansion degree change sequence data of the plastic foam in the starting time period, and the surface smoothness change sequence data of the plastic foam in the starting time period. The output of the variational autoencoder is a predicted video clip of the subsequent heating process of the plastic foam.

[0041] Variational Autoencoder (VAE) is a generative model that can learn the potential representation of data and generate new samples from it. The variational autoencoder includes an encoder and a decoder. The encoder is used to learn the distribution of data and find the potential structure of the data. The decoder is used to generate new samples with similar features from the potential structure learned by the encoder. The trained variational autoencoder model can take as input the heating video of the plastic foam in the starting time period of the foaming machine, the color change sequence data of the plastic foam in the starting time period, the expansion degree change sequence data of the plastic foam in the starting time period, and the surface smoothness change sequence data of the plastic foam in the starting time period, so as to generate a predicted video clip of the subsequent heating process of the plastic foam.

[0042] Variational autoencoders can process sequence data, such as features that change over time in video frames. By taking the heating video of the plastic foam at the beginning of the foaming machine and the time series data of the plastic foam as input, the variational autoencoder can learn the changing rules in the time dimension and use it to predict the predicted video clips of the subsequent heating process of the plastic foam at future time points. The encoder of the variational autoencoder maps the complex input data into a distribution in a latent space that captures the key features of the data. In this way, the variational autoencoder is able to extract important information about the heating process of the plastic foam and represent it as a set of latent variables. The decoder of the variational autoencoder can sample points from the latent space and generate new samples that are similar to the original data. In the application of plastic foam heating, the variational autoencoder can generate predicted video clips of the plastic foam in the subsequent heating process based on the learned distribution.

[0043] In some embodiments, the method further includes: inputting the color change sequence data of the plastic foam in the starting time period, the expansion degree change sequence data of the plastic foam in the starting time period, and the surface smoothness change sequence data of the plastic foam in the starting time period into a judgment model to judge whether the heating process of the plastic foam in the starting time period of the foaming machine is normal.

[0044] The judgment model is a deep neural network model. The input of the judgment model is the color change sequence data of the plastic foam in the starting time period, the expansion degree change sequence data of the plastic foam in the starting time period, and the surface smoothness change sequence data of the plastic foam in the starting time period. The output of the judgment model is that the heating process of the plastic foam in the starting time period of the foaming machine is normal or the heating process of the plastic foam in the starting time period of the foaming machine is abnormal. The deep neural network model includes deep neural networks (DNN). The deep neural network can include multiple processing layers, each processing layer is composed of multiple neurons, and each neuron performs matrix transformation on the data.

[0045] The color change of plastic foam can reflect the changes in its chemical composition and physical state. In the normal heating process, the color change should be smooth and continuous. If the color change is abnormal, such as sudden or discontinuous, it may indicate that there is a problem in the heating process, such as improper temperature control or wrong raw material ratio.

[0046] The expansion degree of plastic foam is an important indicator of its physical changes during heating. The normal heating process will cause the plastic foam to expand to a certain extent. If the expansion degree exceeds the normal range or the rate of change is abnormal, it may mean that there is a problem with the heating process, such as overheating or insufficient reaction of the raw materials.

[0047] The surface smoothness of plastic foam reflects the uniformity and stability of its surface structure. During the normal heating process, the surface of plastic foam should gradually become smooth. If the surface smoothness is abnormal, such as unevenness or local roughness, it may indicate problems such as uneven heating or uneven mixing of raw materials during the heating process. The deep neural network model is able to process these complex sequence data and determine whether the heating process of the plastic foam is normal by learning the complex relationships and patterns between color changes, expansion degree and surface smoothness. The multi-layer structure and large number of neurons of the deep neural network model enable it to capture the subtle differences and deep features in the data, thereby making accurate judgments.

[0048] Step S4, using a time determination model to determine the stop time of the plastic foam heating based on the heating video of the plastic foam in the starting time period of the foaming machine and the predicted video clip of the subsequent heating process of the plastic foam.

[0049] The time determination model is a gated loop unit. The input of the time determination model is the heating video of the plastic foam in the starting time period of the foaming machine and the predicted video clip of the subsequent heating process of the plastic foam. The output of the time determination model is the stop time of the plastic foam heating.

[0050] The stop time of the plastic foam heating is the time at which the heating of the plastic foam is stopped.

[0051] The variational autoencoder learns the underlying patterns of the data through its encoder and decoder structures. This generates more accurate prediction video clips. These underlying structures may not be easy to observe directly from the original data, but they are crucial for predicting the final state of the plastic foam. The variational autoencoder can generate a possible future state, i.e., a prediction video clip, based on the determined plastic foam heating process. This generation ability is very useful for predicting the behavior and changes of plastic foam during the heating process. The plastic foam heating process is essentially a dynamic, time-varying process. The variational autoencoder is particularly suitable for processing this type of time series data because it can learn the dynamic characteristics of data changing over time and predict future development trends. By using the predicted video clips generated by the variational autoencoder as the input of the time determination model, the detailed information in the predicted video clips and the key information in the plastic foam heating process can be better utilized to generate more accurate prediction results and provide strong support for determining the stop time of plastic foam heating. This method is more efficient and reliable than directly using the original data for prediction.

[0052] The heating process of plastic foam in a foaming machine can be represented as a time series, in which each frame of video contains the state information of the plastic foam during the heating process. These video sequence data contain rich time-related information, such as temperature changes, changes in the volume of plastic foam, etc. The gated recurrent unit has the ability to process sequence data and can automatically capture patterns and regularities in time series. Based on the video sequence data of the plastic foam heating process, the gated recurrent unit can learn the feature representation of different stages in the plastic foam heating process. On the trained gated recurrent unit model, the stop time of the plastic foam heating can be predicted by inputting the heating video of the plastic foam at the beginning of the foaming machine and the predicted video clips of the subsequent heating process. During the learning process, the model captures the characteristics of each stage of the heating process, so that it can accurately predict the best time to stop heating to achieve the desired heating effect.

[0053] Step S5, controlling the foaming machine to stop heating based on the stop time of heating the plastic foam.

[0054] After determining the stop time of heating the plastic foam, the foaming machine is controlled to stop heating when the stop time of heating the plastic foam is reached.
