Description

Technical Field

[0001] The present invention relates to the technical field of chips and artificial intelligence systems, and specifically to a microelectronic gas analysis system based on chips and intelligent manufacturing. Background Art

[0002] In recent years, with the rapid advancement of science and technology, the combination of microelectronics technology and intelligent manufacturing is profoundly changing the traditional industrial landscape. The development of microelectronics technology, especially the mature application of MEMS (micro-electromechanical systems), has made the miniaturization and integration of sensors possible, bringing revolutionary changes to the field of gas analysis. At the same time, the application of intelligent manufacturing technology has greatly improved the performance consistency and production efficiency of products through precise control and optimization of production processes, making the mass production of microelectronic gas analysis systems a reality. This technological integration not only reduces the size of the equipment and enhances portability, but also significantly improves the overall performance of the detection system, enabling it to adapt to a wider range of gas monitoring needs, expanding from laboratory research to industrial sites, environmental monitoring and even home safety.

[0003] Despite significant progress in gas analysis technology, traditional analytical instruments still have many shortcomings. These devices are often bulky and complex to install and operate, which not only increases deployment costs but also limits their application in space-constrained or extreme environments. In addition, traditional gas detectors have limited ability to identify specific gases, slow response speeds, and are easily affected by cross-interference, which greatly reduces the accuracy of the analysis results. In actual applications, these defects often require professionals to perform frequent calibration and maintenance, which not only increases labor costs, but also affects the real-time and reliability of data, and cannot meet the growing demand for instant and accurate gas analysis in modern society.

[0004] However, the high cost and complexity of traditional gas analysis technology not only hinder its popularization in small and medium-sized enterprises and remote areas, but also to a certain extent inhibit technological innovation and development in the fields of environmental monitoring and industrial safety. The high maintenance costs and long response time make it impossible to respond quickly in emergency situations, increasing the potential risk of environmental pollution and the probability of safety accidents. In addition, the energy efficiency of these devices is generally low, and long-term operation consumes a lot of electricity resources, which runs counter to the global trend of energy conservation and emission reduction. Therefore, the development of a microelectronic gas analysis system is of great significance to promoting sustainable development, improving public safety and promoting environmental protection. Summary of the invention

[0005] The purpose of the present invention is to make up for the shortcomings of the prior art and to provide a microelectronic gas analysis system based on chips and intelligent manufacturing. By adopting advanced MEMS technology, the system realizes the miniaturization and integration of sensors, which not only greatly reduces the volume, but also significantly improves the sensitivity and response speed of gas detection. The highly sensitive sensing material layer can quickly capture target gas molecules and can achieve accurate detection even under low concentration conditions. At the same time, it effectively reduces cross interference and ensures the high accuracy and reliability of the analysis results.

[0016] (4) Performance testing and calibration: Each sensor unit is subjected to rigorous performance testing, including evaluation of key indicators such as sensitivity, selectivity, response time, and recovery time. The frequency and time domain features that reflect the characteristics of the gas are extracted from the sensor signal through the Fourier transform algorithm to prepare data for subsequent identification and analysis.

[0017] Furthermore, the microelectronic integrated sensor module uses the Fourier transform algorithm to utilize the changes in the time domain contained in the signal generated by the sensor to reflect the fluctuation of gas concentration over time, converts the time domain signal into a frequency domain signal, and identifies the reaction characteristics of the specific frequency component in the signal and the absorption of specific gas molecules. The algorithm formula is: , x is the time domain signal sequence, X[k] is the corresponding frequency domain coefficient, N is the sequence length, It is a rotation factor that decomposes the complex time domain signal into a series of frequency components through calculation, and then extracts the characteristic frequencies and frequency bands related to the target gas, providing key information for gas identification.

For time domain signals, the differential equation is: , y[n] is the filtered signal, x[n] is the input signal, It is a parameter related to the cutoff frequency, which provides a clearer data basis for subsequent gas identification by improving signal quality.

[0024] Furthermore, the intelligent processing and adaptive algorithm module uses a linear regression algorithm for quantitative estimation of gas concentration, and predicts the concentration of unknown gas by establishing a linear relationship model between input characteristics and output gas concentration. The algorithm formula is: , y represents the predicted gas concentration, w is the weight parameter, and b is the bias term.

[0025] Furthermore, the intelligent processing and adaptive algorithm module converts the preprocessed and feature-extracted data into a set of feature vectors, where each vector corresponds to a feature representation of a set of sensor readings. At the same time, each feature vector corresponds to a known gas category label, and a maximum margin hyperplane is found between the two types of samples to achieve optimal classification.

The training data set is ( , ), i=1, 2, 3,...n, is the eigenvector, is the feature vector and the category label, the optimization problem of linear SVM can be expressed as: , for nonlinearly separable data, the original data is mapped to a higher-dimensional feature space, making the originally inseparable problem linearly separable. For new unknown samples x′, classification is performed through decision rules: , through the cross-validation method, it is tuned to adapt to gas detection tasks in different environments. A large number of labeled gas sample data sets are used to train the model to learn the characteristic patterns of different gases. The feature vectors collected in real time are input into the trained model to identify the gas type and estimate the concentration.

[0026] Furthermore, the remote control center module specifically comprises the following steps:

[0027] (1) Data reception: Receive data sent by the low-power remote communication function module through the network interface, including gas composition and concentration information detected by the microelectronic integrated sensor module;
