Abstract
Description
Technical Field
[0001] The present invention relates to the field of monitoring methods and monitoring systems, and more specifically, to a remote monitoring method and a remote monitoring system thereof. Background Art
[0002] With the rapid development of Industry 4.0 and intelligent manufacturing, remote monitoring technology plays an increasingly important role in modern industrial production. Especially in the monitoring of key facilities such as large-scale industrial equipment such as smelting blast furnaces and chemical reactors, the performance of the remote monitoring system is directly related to production efficiency, safety and economic benefits.
[0003] In recent years, remote monitoring technology has evolved from simple data collection to intelligent analysis. Early remote monitoring systems mainly relied on fixed-frequency data collection and simple threshold alarms. With the advancement of technology, more complex data analysis algorithms such as machine learning and deep learning have been introduced to improve the accuracy of anomaly detection. At the same time, in order to cope with the growing amount of data, various data compression and transmission optimization technologies have also been widely used.
[0004] However, despite the progress made in existing technologies, there are still many challenges and shortcomings in the face of the complexity and dynamism of modern industrial production:
[0005] 1. Insufficient adaptability of data collection: Most existing systems use a fixed sampling frequency and cannot be dynamically adjusted according to device status and environmental changes. This may result in insufficient data being collected at critical moments, or a large amount of redundant data being generated under normal conditions, resulting in a waste of resources.
[0006] 2. Low data compression efficiency: Traditional data compression methods often use general algorithms, such as ZIP or GZIP, which cannot fully utilize the characteristics of industrial data. This results in unsatisfactory compression rates or loss of important information when pursuing high compression rates.
[0007] 3. Insufficient network transmission optimization: Existing systems usually use fixed network transmission strategies, which cannot cope with complex and changing industrial network environments. This may lead to high data transmission delays and high packet loss rates, affecting the effect of real-time monitoring.
[0008] 4. Limited anomaly detection accuracy: Although machine learning algorithms have been introduced, most systems still have difficulty in effectively processing multimodal, high-dimensional industrial data. This results in insufficient anomaly detection accuracy and a high risk of false positives and false negatives.
[0009] 5. Slow system response: Due to the inefficiency of each link of data processing, transmission and analysis, the response time of many existing systems is long and cannot meet the needs of time-sensitive industrial scenarios.
[0010] 6. Low energy efficiency: Existing systems often ignore the optimization of energy efficiency, resulting in increased energy consumption while improving monitoring effects.
[0011] Take the industrial remote monitoring system of a well-known company as an example. Although the system has been widely used in large steel plants, it still has significant problems. It uses a fixed sampling interval of 5 seconds, which generates a large amount of redundant data when the blast furnace is operating normally, and may miss key information in emergencies. The system uses the traditional JPEG2000 algorithm for image compression. Although the compression rate reaches 70%, important details are often lost. In terms of anomaly detection, the system uses a rule-based approach combined with a simple statistical model, and has limited processing capabilities for complex multi-source data, resulting in anomaly detection accuracy of only about 85%. In addition, the system's average response time exceeds 5 seconds, which seems to be incapable of handling emergencies.
[0012] In view of the above problems, there is an urgent need for a new remote monitoring method and its remote monitoring system, which can comprehensively improve the efficiency and accuracy of data collection, compression, transmission, analysis and response, while taking into account the optimization of energy efficiency.

[0046] Specifically, the adaptive multimodal compression adopts a hybrid algorithm combining fractal compression and neural compression:

[0090] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation method, structure, features and effects of the intelligent management method based on the enterprise environment proposed by the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures or characteristics in one or more embodiments may be combined in any suitable form.
[0091] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
[0092] A specific solution of a remote monitoring method provided by the present invention is described in detail below with reference to the accompanying drawings.
[0093] Please refer to Figure 1 The present invention provides a remote monitoring method, comprising the following steps:
[0094] Step 1: Acquire the raw data collected by the multimodal sensor array. In the specific implementation of the present invention, taking large-scale industrial smelting equipment as an example, the multimodal sensor array includes temperature sensors, pressure sensors, vibration sensors, gas concentration sensors, and high-definition cameras, etc. These sensors are distributed in key parts of the smelting equipment, such as furnaces, cooling systems, and tail gas treatment devices.
[0095] This step adopts an adaptive sampling frequency strategy:
[0096] f s (t) = f base +Δf·sigmoid(∑w i Δp i (t))
[0097] Among them, f s (t) is the real-time sampling frequency, f base is the base sampling frequency (for example, for a temperature sensor, f base may be 1 Hz), Δf is the adjustable frequency increment (e.g., 0.5 Hz), and w i is the weight of each parameter (for example, temperature change may be more important than pressure change), Δp i (t) is the rate of change of parameter i.
[0098] For example, when a rapid rise in furnace temperature is detected, the system automatically increases the sampling frequency of the temperature sensor to capture more detailed data.
[0099] Step 2: Preprocess the raw data. This step includes two main parts: noise removal and data normalization.
[0100] a) Noise removal, using improved wavelet threshold denoising algorithm:
[0101] X denoised =IDWT(T λ (DWT(X)))
[0102] Where X is the original data (e.g., temperature readings over a period of time), DWT and IDWT are discrete wavelet transform and its inverse transform, respectively, and T λ is the adaptive threshold function:
[0103] T λ (x) = sign(x)(|x|-λ) + (1+exp(-α(|x|-β)))
[0104] λ, α, and β are dynamically adjusted parameters. In practical applications, λ may be adjusted between 0.1 and 0.5, and α and β are optimized according to the characteristics of the signal.
[0105] b) Data standardization, using the improved Z-score standardization method:
[0106]
[0107] Among them, μ is the mean, σ is the standard deviation, ∈ and γ are dynamically adjusted parameters. Usually, ∈ may be between 0.001 and 0.1, and γ is adjusted between 0.1 and 1.
[0108] This improved normalization method is particularly suitable for dealing with extreme values that may occur in smelting equipment, such as sudden temperature peaks.
[0109] Please refer to Figure 2 , Step 3: Perform adaptive multi-modal compression and intelligent transmission. This step is the core of the present invention and includes the following parts:
[0110] a) Use quantum-inspired neural networks for real-time data analysis, where X is the input data (e.g., preprocessed multimodal sensor data), σ is the activation function (e.g., ReLU), W1 and W2 are weight matrices, b1 and b2 are bias vectors, and Q Φ For quantum-inspired nonlinear transformations:
[0111] QHNN(X)=σ(W2·Q Φ (W1·X+b1)+b2)
[0112]
[0113] Importance scoring function:
[0114] I(X)=∑w i QHNN(X i )+λH(X)
[0115] Among them, w i is the weight of each feature (for example, temperature data may be more important than vibration data), H(X) is the entropy of the data, and A is the balance parameter (usually between 0.1 and 0.5). This method can quickly identify key data in the smelting process, such as abnormal temperature fluctuations or sudden changes in gas concentration.
[0116] b) Perform adaptive multimodal compression
[0117] C(X)=αF c (X)+(1-α)N c (X)
[0118] Among them, X is the input data, C(X) is the compression result, and F c is the fractal compression function, N cis the neural compression function, and α is the dynamically adjusted mixing coefficient (usually between 0.3 and 0.7).
[0119] F c (X) = argmin∑D(R i (X), S j (X)
[0120] Among them, R i and S j are range blocks and definition blocks, respectively, and D is the distance function. This method is particularly suitable for compressing data with self-similarity, such as the temperature curve of smelting equipment.
[0121] N c (X)=Decoder(Quantizer(Encoder(X)))
[0122] The Encoder and Decoder use an improved variational autoencoder structure, and the Quantizer uses a soft quantization method, which is suitable for compressing complex multimodal data such as device vibration features and video streams.
[0123] c) Compression quality evaluation
[0124] Q(C(X))=w1R(X,X′)+w2S(X,X′)+w3T(X′)
[0125] Among them, R is the information retention rate, S is the structural similarity, T is the computational complexity, and W1, W2, and W3 are dynamically adjusted weights (the sum is 1). This evaluation method ensures that the compressed data still retains key information in the governance process.
[0126] d) Intelligent transmission scheduling, using the improved AntCo1onyOptimization (ACO) algorithm to optimize the transmission path:
[0127]
[0128] Among them, τ ij is the pheromone concentration, ρ is the evaporation rate (usually between 0.1 and 0.3), and are the pheromone increments of the current best path and the global best path respectively. This method can find the optimal data transmission path in a complex industrial network environment and ensure the timely transmission of key data.
[0129] e) Network self-optimization, using a hybrid optimization method that combines quantum genetic algorithm with deep reinforcement learning:
[0130] Quantum chromosome representation: |ψ>=∑α i|i>
[0131] Quantum revolving door:
[0132] Policy network: π(a|s)=softmax(f θ (s))
[0133] Value Network: V(s) = g φ (s)
[0134] Hybrid optimization objective function: J = w1J QGA +w2J PPO +w3R
[0135] Among them, J QGA is the fitness function of the quantum genetic algorithm, J PPO is the objective function of deep reinforcement learning, R is the regularization term. w1, W2, and W3 are weights (the sum is 1). This method can dynamically adjust network parameters to adapt to the complex and changeable network environment of industrial sites.
[0136] Step 4: Decompress the compressed data. This step uses the decompression algorithm corresponding to the compression:
[0137] For the fractal compression part:
[0138]
[0139] Where X' is the decompression result, W is the iterated function system (IFS) defined in fractal coding, and X0 is the initial estimate. Usually, 10-20 iterations can get good results.
[0140] For the nerve compression part:
[0141] X′=Decoder(Q - 1(Z))
[0142] Among them, Q -1 is the inverse quantization function, Decoder is the trained decoder network, and Z is the compressed data.
[0143] This decompression method can effectively restore various monitoring data of smelting equipment, including temperature curves, pressure changes, gas concentrations, etc.
[0144] Step 5: Fusion and analysis of the decompressed data. This step uses the improved Dempster-Shafer evidence theory:
[0145]
[0146] Among them, m(A) is the basic probability distribution after fusion, mi (A) is the basic probability distribution of the i-th evidence source, K is the conflict degree, and w i The weight is adjusted dynamically.
[0147] This method is particularly suitable for integrating multi-source heterogeneous data of smelting equipment, such as comprehensive analysis of temperature, pressure, gas concentration and other data to obtain a more accurate assessment of the equipment's operating status.
[0148] Step 7: Provide feedback and optimization, and use meta-learning methods for continuous optimization:
[0149]
[0150] Among them, θ is the model parameter, α is the learning rate, and L τ is the meta-learning objective function:
[0151]
[0152] Among them, τ is the task set, D i is the data of the i-th task, and R(θ) is the regularization term.
[0153] Based on the anomaly detection results, the system will automatically adjust the parameters of each module, such as adjusting the sensor sampling frequency, updating the weight of the compression algorithm, optimizing the network transmission path, etc., forming a closed-loop optimization system.

[0227] The test results are shown in the following table:
[0228] Table 1: Performance comparison between examples and comparative examples
[0229] index Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 Data compression rate 92% 70% 85% 88% Data transmission delay (ms) 45 280 120 95 Anomaly detection accuracy 97.5% 85.0% 92.0% 94.5% Energy efficiency improvement 18.5% 5.0% 12.0% 15.0% System response time(s) 1.2 5.8 2.5 2.0 Network bandwidth utilization 65% 95% 80% 75%
[0230] The above results are analyzed and explained as follows:
[0231] 1. Data compression rate: Example 1 achieved a compression rate of 92%, which is much higher than other comparative examples. This is due to the adaptive multimodal compression algorithm of the present invention, which can dynamically adjust the compression strategy according to the importance and characteristics of the data. A high compression rate means lower storage costs and network transmission burden.
[0232] 2. Data transmission delay: The transmission delay of Example 1 is only 45ms, which is 50ms lower than the closest comparative example 3. This is mainly due to the intelligent transmission scheduling and network self-optimization modules of the present invention, which can optimize the transmission path and network parameters in real time. Low latency is crucial for real-time monitoring and fast response.
[0233] 3. Anomaly detection accuracy: The anomaly detection accuracy of Example 1 reaches 97.5%, which is significantly higher than other methods. This demonstrates the superiority of quantum-inspired neural networks in processing complex multimodal data, and the effectiveness of dynamic threshold mechanisms in reducing false positives and false negatives. High accuracy means more reliable monitoring and fewer false alarms.
[0234] 4. Improved energy efficiency: Example 1 achieved an 18.5% improvement in energy efficiency, far exceeding other methods. This shows that the present invention not only improves the monitoring effect, but also significantly reduces energy consumption through precise control and optimization, and has obvious economic and environmental benefits.
[0235] 5. System response time: The system response time of Example 1 is only 1.2 seconds, which is much faster than other methods. This is due to the end-to-end optimization of the present invention, including adaptive sampling, fast compression and efficient transmission. Fast response is crucial for preventing potential accidents and timely intervention.
[0236] 6. Network bandwidth utilization: The bandwidth utilization of Example 1 is 65%, which is lower than that of other methods. This may not seem optimal, but it actually reflects the high efficiency of the present invention. Lower bandwidth utilization means that less network resources are occupied while transmitting the same amount of effective information, leaving more bandwidth for other applications.
[0237] Based on the above results, Example 1 is determined to be the best example. It performs well in all key indicators, especially in data compression rate, transmission delay and anomaly detection accuracy.
[0238] Compared with traditional methods and some improved methods, the remote monitoring method of the present invention shows significant superiority in multiple key indicators. It not only greatly improves the efficiency of data processing and transmission, but also significantly improves the accuracy of anomaly detection and the system response speed. At the same time, while improving the monitoring effect, this method also achieves a significant improvement in energy efficiency, reflecting the combination of technological innovation and sustainable development.
[0239] These results fully demonstrate the effectiveness and advancement of the innovations of the invention, such as quantum-inspired neural networks, adaptive multimodal compression, intelligent transmission scheduling, and network self-optimization. Together, they form an efficient, intelligent, and reliable remote monitoring system, providing strong technical support for Industry 4.0 and smart manufacturing.
[0240] This comprehensive performance improvement not only improves production efficiency and safety, but also brings significant economic benefits to enterprises. For example, an 18.5% improvement in energy efficiency may save millions of yuan in energy costs for large factories each year. At the same time, an anomaly detection accuracy rate of up to 97.5% can effectively prevent equipment failures and production interruptions, further reducing operating costs and risks.
[0241] In general, this invention represents an important breakthrough in industrial remote monitoring technology and provides new possibilities and directions for the digital transformation of the manufacturing industry.
