Environmental particulate matter concentration estimation method, system and terminal based on sensor data

The invention relates to an environmental particulate matter concentration estimation method, system and terminal based on sensor data, the method comprises three links of modeling, evaluation and application, and the three links can be updated and called regularly after being deployed on hardware equipment; in the modeling step, a training time sequence set and modeling configuration parameters are input, and alternative estimation models are output; in the evaluation link, a test time sequence set is input, test errors are output after the test time sequence set passes through the alternative estimation models obtained in the modeling link, and an optimal estimation model can be output according to the alternative estimation model with the minimum test error; in the application link, an original time sequence is input, and after calculation of the optimization estimation model, an estimation time sequence is output; according to the method provided by the invention, after the data of the sensor is subjected
