Abstract: Disclosed are an apparatus and a method for transmitting a tag. The apparatus for transmitting a tag converts 2 bits of a plurality of bit data into one symbol using phase information and orthogonal information. The apparatus for transmitting a tag generates a sub-carrier signal by multiplying the symbol by a square wave having a faster period by a predetermined number of times than a period of the symbol, and transmits the sub-carrier signal to a reader

Abstract: The present invention is directed to reducing non-fire alarms by distinguishing between smoke caused by an actual fire and non-fire smoke generated in daily life when an event suspected to be a fire occurs. The present invention provides an apparatus and method for determining whether a fire occurs using a smoke detector, which includes a light emitter for generating multiple wavelengths, a light receiver configured to detect light scattered by particles of smoke, and a fire determiner for checking whether the strength of a signal of the detected scattered light exceeds a threshold and generating an alarm, to use characteristics of multiple wavelengths in a photoelectric fire detection apparatus. The fire determiner calculates normalized values by normalizing measured values for the scattered light, and calculates a singular value from the normalized values as a criterion for determining whether the smoke is caused by a fire or a non-fire.

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.
