A method and system for detecting fluorescence data change trend

Abstract

A method and system for detecting the changing trend of fluorescence data, comprising the following steps: step 1: receiving and storing fluorescence data in a buffer area; step 2: performing median filtering and 4-point mean filtering on the buffered fluorescence data and then covering and saving them; step 3: preprocessing the fluorescence data, first obtaining the trend determination threshold; step 4: performing trend detection on the fluorescence data saved after processing in step 2 in the initial state; step 5: when the fluorescence data currently being processed has a changing trend, it is necessary to continue to detect whether the subsequent fluorescence data conforms to the changing trend. The present invention can quickly determine the most likely state of non-explosives and strong positive explosives in security inspections by studying the differences in the initial specific reactions of multi-channel data to non-explosives and explosives, thereby greatly improving the speed of a single detection, but the premise is also to obtain the changing trend of fluorescence data in a short period of time.
