Abstract: Provided is a Raman scattering measurement apparatus including a light source which emits light to smoke particles, a filter configured to block light which is incident to the smoke particles and passes through the particle and to allow Raman scattered light to pass therethrough, and a photodetector which detects the Raman scattered light passing through the filter in order to distinguish fire smoke generated due to a true fire from non-fire smoke generated due to daily life or industrial activity. The present invention also provides a fire determination apparatus including a unit which reads a Raman shift from Raman scattered light detected by the photodetector of the Raman scattering measurement apparatus, estimates a smoke component from the read Raman shift, and determines fire/non-fire from the estimated smoke component and a method thereof.

Abstract: Optical data is collected from an optical sensor of a dual wavelength, and in order to detect the fire from the collected optical data, an average value of a first wavelength, an average value of a second wavelength, and a ratio of the average values of the two wavelengths are calculated, and an amount of change of a slope of the ratio is used to detect the fire and determine the fire occurrence time. From the determined fire occurrence time, fire features are extracted from the optical data in real time according to defined rules to configure a data set. The data set may be used for learning and inference techniques to identify a fire or non-fire, a fire source, a combustion material, and the like.

Abstract: A walking analysis method includes measuring impacts due to floor landing occurring during walking; identifying an impact section before floor landing, a free fall section, and an impact peak section by floor landing in an impact graph over time; analyzing at least one impact-related parameter for the impact section before floor landing, the free fall section, and the impact peak section by floor landing; and determining a walking-related accident type according to a result of analyzing the at least one impact-related parameter. Accordingly, by classifying and detecting a variety of accidents that may actually occur, the main walking characteristics that are dangerous in the actual accident can be extracted.
