Title:
FIRE DETECTION SYSTEM AND FIRE DETECTION METHOD
Document Type and Number:
Japanese Patent JP2022031076
Kind Code:
A
Abstract:
To enable accurate and reliable fire detection by observing light emitted from a monitored area.SOLUTION: An observation unit 12 observes light emitted from a monitored area and collects first observation data in the flame-specific wavelength band emitted from the flame in response to a fire and second observation data in the non-flame wavelength band. A first processing unit 14 obtains a first fire determination result by processing the first and second observation data for fire determination. A second processing unit 16 collects and machine-learns the first and second observation data at least during normal monitoring as training data in advance, and then inputs the newly observed first and second observation data to calculate the second fire determination result. A fire detection unit 18 detects fire based on the first and second fire determination results.SELECTED DRAWING: Figure 1
