Description
Technical Field
[0001] The invention relates to the technical field of sludge treatment, in particular to an equipment adaptive control method for sludge treatment. Background Art
[0002] During the operation of sludge treatment equipment, its status monitoring and fault diagnosis have an important impact on the safety, operation efficiency and maintenance cost of the equipment. However, the operating environment of sludge treatment equipment is complex and changeable, involving a variety of operating parameters (such as temperature, pressure, humidity, vibration, etc.) and a variety of fault types (such as minor faults and serious faults). Accurate identification and control of equipment status are of great significance to optimizing operation efficiency, reducing downtime and reducing maintenance costs. In the prior art, equipment status identification and fault diagnosis mainly rely on centralized model training. This method requires the original operation data of the equipment to be centrally transmitted to a central server for processing. However, the operation data of sludge treatment equipment often involves sensitive information, and centralized transmission may lead to data privacy leakage. In addition, there is a phenomenon of insufficient sample size in the collection of operation data of sludge treatment equipment, especially under different equipment and working conditions. The scarcity of samples limits the generalization ability of the model. In order to solve the problem of insufficient data, traditional data expansion methods cannot effectively generate diversified high-quality data samples, and there is a significant deviation from the distribution of actual equipment operation status, which further affects the recognition accuracy of the model.
[0003] The existing Chinese invention patent CN117105502A proposes an adaptive sludge treatment control system and control method based on machine learning, which belongs to the field of sludge treatment technology. It solves the technical problems of reduced performance and efficiency of the sludge treatment process, and even failures or accidents. The sludge treatment control system includes a sludge treatment device, which is used to perform anaerobic digestion, dehydration and drying treatment processes on the incoming sludge; a sensor module is arranged at different positions of the sludge treatment device, which is used to detect various parameters of the sludge, including temperature, pressure, humidity, pH value, organic matter content, and ammonia nitrogen content; a control module is connected to the sensor module and the sludge treatment device, and is used to adjust various operating parameters of the sludge treatment device according to the sludge parameters detected by the sensor module. The sludge treatment control method includes four steps. The present invention can realize adaptive control of sludge of different types and states, and improve the energy consumption, efficiency and quality indicators of sludge treatment.
[0004] Although the above technical solution can realize adaptive control of sludge of different types and states, the following problems still need to be further solved:
[0005] 1. In the adaptive control task of equipment used for sludge treatment, when there are few data samples of sludge treatment equipment, the samples generated by traditional data augmentation methods are of low quality and lack feature distribution consistent with real data, resulting in insufficient generalization ability of model training.
[0006] 2. In the adaptive control task of equipment used for sludge treatment, traditional neural network optimization methods mostly use gradient descent algorithms, which are prone to fall into local optimality in complex nonlinear problems. At the same time, the training efficiency is low, which affects the feature extraction effect and classification accuracy of sludge treatment equipment state recognition. Summary of the invention

[0031]
[0032] Where M() is the mapping function; α ch is the manifold learning rate; Dist() represents the distance function between the generated features and the sludge treatment equipment data manifold; U ed It is the data manifold feature of sludge treatment equipment; Indicates F′ (l) gradient.

[0045] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the application equally.
[0046] The present invention proposes an adaptive control method for sludge treatment equipment, which monitors the state of the sludge treatment equipment through an equipment state recognition model, and then makes corresponding control strategies, which are as follows:
[0047] S1. Obtain data on cleaning equipment used for sludge treatment. These equipment are equipped with multiple sensors that can monitor various environmental and operating status parameters of the equipment in real time. The specific data collected include but are not limited to multi-dimensional information such as the equipment's operating temperature, pressure, speed, current, voltage, vibration, humidity, etc.
[0048] Using a multi-point distributed sensor architecture, sensors are placed on key components of sludge treatment equipment (such as transmission systems, filter presses, heating devices, etc.) to ensure that real-time status information of the equipment can be captured from multiple dimensions. Through real-time sampling technology, all sensor data will be collected at fixed time intervals (for example, every second or every millisecond) and stored in the local server;
[0049] The collected data is stored in a timestamp serialized structured data file (such as JSON or CSV format). Each record contains a timestamp and the reading corresponding to each sensor. In one embodiment, the attributes of the data include:

[0051] It should be noted that this embodiment is only used to illustrate one data format and type of the present invention. In actual applications, the attributes of data are usually more than 10 attributes, and the number of attributes of data may reach dozens or even hundreds.
[0052] Then, the collected data is labeled. The labeling method of the present invention is manual labeling. In one embodiment, the labeled categories include: normal state, minor fault, major fault, and equipment maintenance, a total of 4 categories.
[0053] S2. In the task of the present invention, the collection, acquisition, labeling and preprocessing of the sludge treatment equipment training data are time-consuming and labor-intensive, and insufficient data samples for training the sludge treatment equipment can easily lead to poor generalization ability of the model and affect the accuracy of the model. Therefore, a generative adversarial network algorithm based on feature fusion is constructed and trained to obtain a data expansion model after training, thereby realizing data expansion of the sludge treatment equipment.
[0054] Specifically, the generative adversarial network based on feature fusion includes two main components: a generator and a discriminator; the generator is responsible for generating realistic sludge treatment equipment data samples, and the discriminator is responsible for distinguishing the generated sludge treatment equipment data samples from the real sludge treatment equipment data samples. The present invention adopts a feature fusion mechanism in the traditional generative adversarial network, and uses the features extracted from the real sludge treatment equipment data samples to guide the processing of the generated features, thereby improving the diversity and quality of the generated sludge treatment equipment data samples.
[0055] Specifically, the training process of the generative adversarial network algorithm based on feature fusion is as follows:

[0062] In the formula, F (l) represents the output feature vector of the lth layer, z is the noise vector from the normal distribution, is the parameter of the generator at layer l, f (l) () is the convolution function of the generator layer l.
[0063] S203. In the feature fusion process, the generator uses the features extracted from the real sludge treatment equipment data sample to guide the processing of generating features, which is expressed as:

[0065] In the formula, is the feature extracted by the generator from the real sludge treatment equipment data sample; F′ (l) represents the output fusion feature of the generator layer l; cb is the fusion weight; x represents the real sludge treatment equipment data sample. Preferably, λ cb Represents a real sludge treatment equipment data sample; are the parameters of the discriminator at layer l.
[0066] S204, the generated features are sent to the adaptive manifold learning module, which dynamically adjusts the feature space according to the underlying geometric structure of the sludge treatment equipment data sample. Specifically, the generated features are adjusted to adapt to the manifold structure of the sludge treatment equipment data through a mapping function, which is expressed as:
[0067]
[0068] Where M() is the mapping function; α ch is the manifold learning rate; Dist() represents the distance function between the generated features and the sludge treatment equipment data manifold; U ed It is the data manifold feature of sludge treatment equipment; Indicates F′ (l) Preferably, αch Set to 0.01.
[0069] Further, the distance function is used to calculate the distance between the generated feature and the sludge treatment equipment data manifold. In one embodiment, the calculation method is expressed as:
[0070]
[0071] Where Ne is the dimension of the feature, is a nonlinear projection function that projects the eigenvector onto the manifold U ed Above; |||| is the L2 norm.
[0072] S205, the task of the discriminator is to evaluate the difference between the generated sludge treatment equipment data sample and the real sludge treatment equipment data sample. In each iteration, the discriminator receives the generated sludge treatment equipment data sample and the real sludge treatment equipment data sample from the generator, and calculates a discrimination result through its network structure, that is, whether the sludge treatment equipment data sample is generated or real. The loss function of the discriminator is calculated as:
[0073]
[0074] Where, L D is the loss function of the discriminator; D() represents the output of the discriminator; Represents the sludge treatment equipment data generated by the generator.
[0075] Moreover, the goal of the generator is to deceive the discriminator as much as possible, so that it misjudges the generated sludge treatment equipment data samples as real sludge treatment equipment data samples, while the goal of the discriminator is to correctly distinguish between real and generated sludge treatment equipment data samples. The loss function of the generator is calculated as:
[0076]
[0077] Where, L G is the loss function of the generator; β vk is a coefficient that adjusts the importance of the two parts. Preferably, β vk Set to 0.3.
[0078] S206. Use the gradient descent method to update the parameters of the generator and the discriminator. The update method is expressed as:
[0079]
[0080] In the formula, γ G and γ D are the learning rates of the generator and the discriminator respectively; ← represents the parameter update operation; and Represent the parameter gradients of the generator and the discriminator respectively. Preferably, γ G and γ d Both are set to 0.03.
[0081] S207, repeat the above steps until the preset stop iteration condition is met, which means the model training is completed. In one embodiment, the preset stop iteration condition is reaching a preset maximum number of iterations, preferably, the preset maximum number of iterations is set to 1000 times.
[0082] After the sludge treatment equipment data expansion model is trained, the number of sludge treatment equipment data samples is increased using the trained sludge treatment equipment data expansion model. In one embodiment, assuming that the original collected sludge treatment equipment data samples are 800, and the sludge treatment equipment data expansion model generates 200 samples by expansion, the expanded sludge treatment equipment data set contains 1000 samples.
[0083] S3. Construct an equipment state recognition model based on a federated learning architecture, wherein the federated learning architecture has multiple clients, each client has a local equipment state recognition model, and the local equipment state recognition model is trained on the sludge treatment equipment data of the respective client, and the local equipment state recognition model interacts with the central equipment state recognition model.
[0084] Specifically, the federated learning architecture proposed in the present invention has multiple clients, marked as client 0, client 1, client 2 and client 3, etc. These clients represent independent nodes in the federated learning network. Each client has its own local sludge treatment equipment data. Each client has a local equipment state recognition model. These local equipment state recognition models are trained on the sludge treatment equipment data of their respective clients. The local equipment state recognition model interacts with the central equipment state recognition model, that is, the update flow of the equipment state recognition model parameters. Fed ′ represents the updated device state recognition model parameters after local training, θ fed Represents the parameters received from the central device state recognition model.
[0085] Among them, the central device state recognition model aggregates updates from local device state recognition models, and the update of the global device state recognition model is a way for the federated learning process to aggregate individual updates to create a new improved global device state recognition model. After the global device state recognition model is updated, the final trained device state recognition model is obtained.
[0086] In one embodiment, the device state identification model parameters arrive exchanging between the local device state identification model and the central device state identification model, wherein the exchanging method allows the central device state identification model to be aggregated and updated, and allows the local device state identification model to receive new, aggregated parameters;
[0087] Further, through multiple iterations, the local device state recognition model is trained, the updates are sent to the central device state recognition model, a global update is performed, and then the updated parameters are sent back to the local device state recognition model;
[0088] Based on this federated learning architecture, the privacy protection of sludge treatment equipment data can be achieved. During the training process, the original sludge treatment equipment data is not shared between clients or with the central server, but only the equipment state recognition model parameters are exchanged for updating. That is, the parameters are synchronized to each client through the central equipment state recognition model. fed ’ is assigned to each client.
[0089] Furthermore, the equipment status recognition model of each client adopts a neural network based on simulated optical optimization. The simulated optical approach regards the parameter optimization problem of the neural network as a light propagation process, simulates the path selection and intensity adjustment of the light beam to optimize the parameter setting. Compared with the traditional gradient descent method, this simulated optical approach does not rely on error gradient information, but optimizes through the light beam propagation effect, avoiding the limitations of gradient information in nonlinear complex problems and deep networks, thereby improving the optimization efficiency and reducing the risk of falling into local optimality, and improving the neural network's ability to extract features from sludge treatment equipment data.
[0090] Specifically, the training process of the neural network algorithm based on simulated optical optimization is as follows:
[0091] S301, using the initial parameters of the neural network as the emission point of the light source, each parameter corresponds to a light source, and its light intensity represents the initial value of the parameter. The initial intensity distribution of the light source is expressed as:
