This invention relates to the field of tobacco product quality testing, and more particularly to a rapid detection system and method for aroma concentration in flavor-enhancing cigarettes. The detection system includes a carrier gas supply module, an aroma sampling module, and a gas detection module connected sequentially along a gas path. The carrier gas supply module is used to adjust a first preset parameter value to provide a target clean carrier gas. The aroma sampling module is used to drive the target clean carrier gas to flow through the sample to be tested at a second preset parameter value, generating an aroma-carrying gas. The gas detection module is used to detect the concentration of the target aroma substance in the aroma-carrying gas. This invention can highly simulate the real smoking environment and achieve standardized gas generation and collection, thereby providing stable, reliable, and sensorily correlated gaseous samples for rapid detectors such as PID, and achieving efficient and accurate evaluation of the aroma concentration consistency of flavor-enhancing cigarette products.

This invention discloses a method and device for monitoring patchy fog based on a visible light image sensor and a point laser, belonging to the field of atmospheric visibility monitoring technology. The device includes a linearly calibrated visible light image sensor, a point laser emitter mounted parallel to the sensor's optical axis, and a synchronization control and data processing unit. The core of the method lies in: synchronously controlling and alternately acquiring image pairs of the laser being on and off, performing differential analysis to eliminate background interference, and obtaining a pure laser atmospheric scattering signal; integrating along the laser spot normal direction to obtain an initial brightness profile curve; based on the fixed spatial pose relationship between the sensor and the laser, mapping the brightness curve in image coordinates to a corrected brightness curve in real spatial distance coordinates through a geometric correction model; calculating the mean and variance of the corrected brightness curve, and calibrating it using standard instruments; and finally simultaneously obtaining the average path visibility value and the patchy fog intensity index. This invention is low-cost, has strong anti-interference capabilities, and can effectively achieve quantitative identification and spatial positioning of patchy fog, making it suitable for large-scale deployment in scenarios such as highways.
