Abstract

The invention relates to a NOx emission prediction method and device, electronic equipment and a computer storage medium, and the method comprises the steps: obtaining sample data including a training set, a verification set and a test set, and outputting the sample data including NOx emission; inputting the training set into the initial SVR model for training, generating a first NOx emission prediction model, and obtaining parameters influencing the performance of the first NOx emission prediction model; inputting the verification set into a first NOx emission prediction model, optimizing parameters based on a PSO algorithm to obtain optimized parameters, and obtaining a second NOx emission prediction model based on the optimized parameters; and inputting the test set into a second NOx emission prediction model for prediction, and outputting a NOx emission prediction result. According to the method, an accurate prediction result is obtained, and whether the NOx sensor breaks down or not is diagnosed in time.

Description

technical field [0001] The invention relates to the technical field of model prediction, in particular to a NOx emission prediction method, device, electronic device and computer storage medium. Background technique [0002] Vehicles are the main contributor to the total pollutant emissions, which emit CO (carbon monoxide), HC (total hydrocarbons, including alkanes, olefins, aromatics, etc.), NOx (nitrogen oxides, including nitrogen monoxide and nitrogen dioxide) and PM (particulate matter) exceeds 90%, of which NOx emissions from heavy-duty trucks account for 83.5% of NOx emissions from automobiles. Therefore, it is particularly important to strengthen the supervision of heavy-duty diesel vehicle emissions. [0003] In the prior art, SCR (Selective Catalytic Reduction) technology is usually used to treat NOx in the exhaust emissions of diesel vehicles. Among them, the NOx sensor used in the SCR system of heavy-duty diesel vehicles is mainly electrochemical, and there is NH3...
