  • Collection method for particulate matter detector
    Patent number: 12710413
    Abstract: The present invention relates to a collection method for a particulate matter detector, including: performing normalized calculation on collected initial air particulate matter values, to calculate an initial particulate matter variation among the initial air particulate matter values; obtaining a real-time collection cycle coefficient by performing calculation on the initial particulate matter variation through a stepwise approximation method and table lookup, and calculating a real-time particulate matter collection interval time; then, collecting an air particulate matter value again after the real-time collection interval time, where the air particulate matter value collected at this time is a latest air particulate matter value; performing normalized calculation on the latest air particulate matter value and a data value displayed by the particulate matter detector, to calculate a real-time particulate matter variation; and obtaining a new real-time collection cycle coefficient by performing calculation
