AI Technical Summary
In existing technologies, when using light scattering to detect indoor particulate matter concentration, the accuracy of the detection results is insufficient because the intensity ranges of scattered light corresponding to different types of particulate matter overlap.
By performing regression analysis on historical scattered light intensity data and historical concentration values, the regression error coefficient and intersection influence factor are calculated. The intersection influence factor is corrected according to the change characteristics, and concentration compensation is performed when necessary to improve detection accuracy.
This reduces the impact of overlapping scattered light intensity ranges corresponding to different types of suspended particulate matter on the detection results, thus improving the accuracy of indoor suspended particulate matter concentration detection.
