[0020] Hereinafter, example embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all embodiments of the present application. It should be understood that the present application is not limited by the example embodiments described herein.
[0021] Figure 1 FIG. 1 is a flowchart of a methanol vehicle emission detection strategy management method according to an example embodiment of the present application. As shown in FIG. 1, the methanol vehicle emission detection strategy management method includes the following steps: Figure 1 The sensor configuration parameters, state parameters and historical emission detection strategy parameters of a methanol vehicle are collected. The feature information of the sensor configuration parameters is extracted. The feature information of the state parameters is extracted. The current emission detection strategy parameters are determined based on the feature information of the sensor configuration parameters, the feature information of the state parameters and the historical emission detection strategy parameters. That is, the sensor configuration parameters and the state parameters of the methanol vehicle are collected in real time, and the feature information is extracted. The feature information of the sensor configuration parameters, the feature information of the state parameters and the historical emission detection strategy parameters are comprehensively considered to comprehensively consider the complex relationship between different parameters and the information between time sequences, so that the emission detection strategy of the methanol vehicle is more accurately determined, and the accuracy and adaptability of the detection system are improved.
[0022] Step 110: Collect sensor configuration parameters, status parameters, and historical emission detection strategy parameters of the methanol vehicle.
[0023] The data acquisition system of this application consists of three main parts working together: a cloud platform, a T-BOX, and emission testing equipment. The cloud platform serves as the core data processing and storage hub, undertaking key tasks such as data management, analysis, and equipment calibration. The T-BOX acts as a bridge between the vehicle and the cloud platform, responsible for collecting and uploading vehicle operation data. The emission testing equipment focuses on the accurate collection of exhaust emission data. These three parts work closely together to achieve comprehensive, efficient collection, transmission, and in-depth processing of various data from methanol vehicles.
[0024] The T-BOX is the core device for vehicle data acquisition, connecting to the complex electronic control unit (ECU) network inside the methanol vehicle via a standard OBD interface. The OBD interface follows specific communication protocols, such as ISO 15765 and SAE J1939. The T-BOX utilizes its integrated protocol parsing chip to analyze signals transmitted from the ECU according to these protocols, thereby acquiring a wealth of vehicle operating data. This includes data such as vehicle speed, engine speed, coolant temperature, and oil pressure.
[0025] These data are collected rapidly at a set frequency (e.g., once per second). The collected data is initially processed and cached in the high-speed cache chip inside the T-BOX, waiting to be aligned with the data from the emission detection equipment.
[0026] The emission detection equipment is installed at a key location in the exhaust pipe of methanol vehicles. It uses a variety of advanced sensor technologies to achieve real-time and accurate detection of various emissions and their concentrations.
[0027] Carbon monoxide (CO) and carbon dioxide (CO) Detection: A non-dispersive infrared (NDIR) sensor is used, which detects concentration based on the absorption characteristics of different gases for specific wavelengths of infrared light. Taking CO detection as an example, when infrared light passes through exhaust gas containing CO, some of the infrared light is absorbed by CO, according to Lambert-Beer's Law. The CO concentration was calculated, where The intensity of infrared radiation after the exhaust gas passes through. The initial infrared intensity, This represents the absorption coefficient of CO for a specific wavelength of infrared light. CO concentration, This represents the propagation path length of infrared light in the exhaust gas. This is achieved by measuring... and known The CO concentration can then be calculated.
[0028] Nitrogen oxides (NOx) detection: A chemiluminescence sensor is used to react NOx in the exhaust gas with a specific chemical reagent to generate a light signal. The intensity of the light signal is proportional to the NOx concentration. The light signal is converted into an electrical signal by a photodetector, and after amplification and processing, the NOx concentration is calculated based on a pre-calibrated light intensity-concentration curve.
[0029] Particulate matter (PM) detection: Particulate matter sensors are used, such as electrostatic induction sensors or laser scattering sensors. Taking electrostatic induction sensors as an example, particulate matter generates electrostatic charges when moving in exhaust gas. The amount of charge detected by the sensor is related to the mass concentration or number concentration of particulate matter. The PM concentration is calculated by using the calibrated charge-concentration relationship.
[0030] The emission detection equipment collects emission data at a set frequency (e.g., once every 5 seconds) and temporarily stores this data in a local high-performance flash memory chip.
[0031] Because the T-BOX and emissions testing equipment have different data acquisition frequencies, strict data alignment processing is required to ensure the consistency and correlation of the data uploaded to the cloud platform. Both the T-BOX and emissions testing equipment have built-in high-precision real-time clock modules (RTC) and achieve time synchronization through GPS or network time synchronization to ensure that each data point is accurately timestamped.
[0032] Before data transmission, a time window-based pairing algorithm is used. A time error range (e.g., ±0.5 seconds) is set as the time window. For vehicle operation data collected by the T-BOX at a certain moment, emission data with timestamps within this time window are searched for and paired in the emission detection equipment's data. For example, for vehicle speed data at 10:00:00, emission data with timestamps between 9:59:59.5 and 10:00:00.5 are searched for and paired to form a complete dataset for subsequent uploading to the cloud platform for unified analysis.
[0033] The data after data alignment processing is uploaded to the cloud platform through a high-speed and stable wireless network (such as 4G, 5G). T-BOX and emission detection equipment respectively establish a reliable TCP / IP connection with the cloud platform through the built-in communication module (such as 4G / 5G module), and send the packaged data to the specified server port of the cloud platform according to the specific communication protocol (such as MQTT, HTTP). After receiving the data, the cloud platform first performs data format verification to ensure the integrity and accuracy of the data, and then stores different types of data in the corresponding database table, such as storing vehicle operation data in the vehicle operation data table of the MySQL relational database and storing emission data in the InfluxDB time series database, to prepare for subsequent data analysis and processing.
[0034] The cloud platform configures a special emission detection equipment accuracy calculation algorithm to regularly calibrate the emission detection equipment and ensure its long-term stable and accurate operation. A large number of emission data samples under different working conditions are collected, including the concentration data of exhaust emissions of the vehicle under idle, acceleration, constant speed, and deceleration. The collected data is preprocessed to remove abnormal values and noise data. For example, for CO concentration data, if a data point exceeds the normal range (such as greater than 10%) and differs greatly from the previous and subsequent data points, it is determined as an abnormal value and is removed.
[0035] Combined with the running conditions of the vehicle (such as vehicle speed, engine speed, etc.), the theoretical emission concentration value of each sample is calculated using an empirical formula or a method based on a physical model. Taking NOx emission as an example, for a certain engine speed and load rate , the theoretical NOx concentration is calculated according to the empirical formula , where is the empirical coefficient
[0036] The actual concentration value measured by the emission detection equipment is compared with the theoretical concentration value to calculate the deviation value . By statistical methods (such as the least squares method), a large number of deviation values are analyzed to determine the systematic error and random error of the emission detection equipment. Let the measured data be (the actual concentration value), the theoretical value be , and the fitted straight line equation be . According to the least squares method, the and values that make minimum are solved, where represents the systematic error, represents the deviation of measurement sensitivity.
[0037] Based on the error analysis results, calibration parameters are generated, such as the sensor gain coefficient. and offset For a linear sensor, if the actual measurement sensitivity is... The theoretical sensitivity is Then the gain coefficient Offset .
[0038] Calibration parameters are transmitted to the emission detection equipment via a wireless network, and the equipment calibrates its own measurement data based on these parameters. For example, for newly measured emission concentration values... calibrated concentration value This improves the accuracy of measurements.
[0039] Through such a comprehensive and meticulous hardware system design and rigorous and scientific data processing procedures, it is possible to achieve comprehensive and accurate collection of methanol vehicle emission data and vehicle data. Furthermore, through the calibration algorithm of the cloud platform, the long-term stability and accuracy of the emission detection equipment are ensured, providing solid and reliable data support for methanol vehicle emission monitoring and vehicle operation status analysis.
[0040] Step 120: Extract feature information of sensor configuration parameters.
[0041] The sensor configuration parameters specifically include four dimensions: sensor type, number of sensors, sensor location, and monitored object. All sensor configuration parameters form a high-dimensional data set, with each parameter carrying a timestamp. This application reduces the data volume of sensor configuration parameters by extracting their feature information, thereby reducing the computational complexity for determining subsequent emission detection strategy parameters.
[0042] Step 130: Extract feature information of state parameters.
[0043] The state parameters of methanol vehicles include multiple states across multiple dimensions, and each state parameter carries a timestamp. This application reduces the amount of data for state parameters by extracting feature information, thereby reducing the computational difficulty for determining subsequent emission detection strategy parameters.
[0044] Step 140: Determine the current emission detection strategy parameters based on the feature information of the sensor configuration parameters, the feature information of the state parameters, and the historical emission detection strategy parameters.
[0045] This application combines the characteristic information of sensor configuration parameters, the characteristic information of state parameters, and historical emission detection strategy parameters. Under the premise of integrating data from multiple dimensions, it also considers the correlation of emission detection strategies over time, so as to improve the accuracy and adaptability of the current emission detection strategy.
[0046] This application provides a management method for methanol vehicle emission detection strategies. This method involves collecting sensor configuration parameters, status parameters, and historical emission detection strategy parameters of the methanol vehicle; extracting feature information from the sensor configuration parameters; extracting feature information from the status parameters; and determining the current emission detection strategy parameters based on the feature information from the sensor configuration parameters, status parameters, and historical emission detection strategy parameters. Specifically, by collecting sensor configuration parameters and status parameters of the methanol vehicle in real time and extracting their feature information, and by integrating the feature information from the sensor configuration parameters, status parameters, and historical emission detection strategy parameters, the method comprehensively considers the complex relationships between different parameters and the information between time series, thereby more accurately determining the emission detection strategy for the methanol vehicle and improving the accuracy and adaptability of the detection system.
[0047] In one embodiment, step 120 can be implemented by using an autoencoder to extract features from the sensor configuration parameters to obtain feature information of the sensor configuration parameters.
[0048] This application employs an autoencoder to extract features and reduce the dimensionality of sensor configuration parameters. The autoencoder includes an encoder and a decoder. Specifically, the high-dimensional data set formed by the sensor configuration parameters is denoted as... (wherein, the dimension is) The encoder converts high-dimensional data into... Mapping to a low-dimensional latent space representation The decoder then represents the low-dimensional representation. The original data space is restored, and feature information of the sensor configuration parameters is extracted through encoding and decoding operations.
[0049] In one embodiment, the method for determining the parameters of the autoencoder may be as follows: an encoder is used to encode and calculate the training samples to obtain the sample features of the training samples; a decoder is used to decode and calculate the sample features to obtain the reconstructed samples of the sample features; the reconstruction difference between the training samples and the reconstructed samples is calculated; if the reconstruction difference is greater than a preset difference threshold, the parameters of the encoder and the decoder are adjusted until the reconstruction difference is less than the difference threshold.
[0050] Specifically, the encoding process can be implemented using a fully connected neural network, for example:
[0051]
[0052] in, For activation functions (such as ReLU). and These are the weight matrices and bias vectors for each layer. The calculation results for each layer, The number of layers in the encoder. Dimensions This refers to the dimension after dimensionality reduction, which mainly reflects the types of sensor configurations and the configuration strategies for each type of sensor.
[0053] The decoder is used for error calculation during training. It adjusts the parameters of the encoder and decoder through backpropagation to minimize the reconstruction differences, for example:
[0054]
[0055] in, and These are the weight matrices and bias vectors for each layer. The calculation results for each layer, This represents the number of layers in the decoder.
[0056] The formula for calculating the reconstruction difference is:
[0057]
[0058] in, For the sample size, and The first The original and reconstructed data of each sample.
[0059] In one embodiment, step 130 can be implemented as follows: dividing the state parameters into key state parameters and non-key state parameters; merging all non-key state parameters to obtain merged state parameters; and obtaining the feature information of the state parameters based on the key state parameters and the merged state parameters.
[0060] For the state parameters of methanol vehicles (Assuming it contains) The state parameters are divided into several state dimensions (state values). Based on a state-focused strategy, key state dimensions are identified. For example, by analyzing historical data or expert knowledge, certain state dimensions (such as engine speed, vehicle speed, and intake air volume) are determined to have a significant impact on the emission detection strategy, and these key state dimensions are marked. Non-key state dimensions are merged into a new feature dimension, thereby reducing the dimensionality of the state parameters to a single feature dimension. dimension( It retains key status information and highlights the impact of key status dimensions on emission detection strategies.
[0061] In one embodiment, step 130 can be implemented by performing a weighted average calculation on all non-key state parameters to obtain the merged state parameters.
[0062] For non-key state dimensions, the application can use simple weighted average or other fusion methods to combine them into a new feature dimension.
[0063] In an embodiment, the specific implementation of step 140 can be: inputting the feature information of the sensor configuration parameters, the feature information of the state parameters, and the historical emission detection strategy parameters as input quantities into the network model to obtain the current emission detection strategy parameters.
[0064] The reduced dimension sensor configuration parameters and the methanol vehicle state parameters are spliced together as part of the input of the neural network, with a dimension of , and the historical emission detection strategy parameters are input as input quantities into the neural network model to obtain the current emission detection strategy parameters.
[0065] In an embodiment, the network model includes multiple control gates; wherein the specific implementation of step 140 can be: inputting the historical emission detection strategy parameters as input quantities into the multiple control gates to obtain the feature information of the historical emission detection strategy parameters; inputting the feature information of the sensor configuration parameters, the feature information of the state parameters, and the feature information of the historical emission detection strategy parameters as input quantities into the network model to calculate the current emission detection strategy parameters.
[0066] The long short-term memory (LSTM) model is used to extract features from the historical emission detection strategy parameters. Assuming that the historical emission detection strategy parameters include detection frequency data of multiple sensors at multiple time steps , the data is sorted into a sequence format suitable for LSTM input to obtain the current emission detection strategy parameters, wherein is the detection frequency vector at the th time step.
[0067] Specifically, LSTM processes time series data through a gating mechanism, and its core formula is as follows:
[0068] Input gate:
[0069]
[0070]
[0071] State update:
[0072]
[0073] Output gate:
[0074]
[0075] wherein, is a sigmoid function, and are sigmoid function values, tanh is a hyperbolic tangent function, is a hyperbolic tangent function value, , are weight matrices, are bias vectors, is an output hidden state of the LSTM at the time step, is a state parameter at the time step.
[0076] After the LSTM processing, the output hidden state at the last time step is taken as a reduced dimension representation of the historical emission detection strategy parameter, and the dimension is The time sequence feature not only captures the trend of the change of the historical detection strategy, but also serves as an input directly affecting the structure parameters of the neural network model and a parameter directly affecting a special neuron of the neural network. Meanwhile, the reduced dimension sensor configuration parameter and the methanol vehicle state parameter are spliced together as part of the input of the neural network. The reduced dimension sensor configuration parameter , the methanol vehicle state parameter and the feature information of the historical emission detection strategy parameter can also be spliced together as part of the input of the neural network.
