Intelligent scent management system with perceptual maintenance control and authorization verification mechanism

Abstract

This invention presents a smart fragrance management system with a perception-maintaining control and authorization verification mechanism, comprising a fragrance device, a control server, and a perception control engine. The control server issues time-sensitive authorization tokens and determines the range of perceptual control functions that can be executed based on the user's subscription status. The fragrance device verifies the validity of the authorization tokens for control commands and outputs the scent upon successful verification. The perception control engine generates a discontinuous stimulus sequence based on adaptation time parameters, switching the scent output between release and stop segments, and adjusting the duration of each segment according to environmental compensation parameters to accommodate the adsorption characteristics of spatial materials and gas flow characteristics. Through perception threshold control and a closed-loop feedback learning mechanism, the scent output strategy is dynamically adjusted to maintain the user's perception intensity within the effective perception range.
