AIM(AI Monitoring)-fire is a solution for remote detection of fire from the initial stage by detecting CO or CO2 gas generated at the fire site.

Remote Initial Fire Detection Solution

A widely used method for remote fire detection is a method that detects the occurrence of high temperature using a thermal imaging camera and determines that it is a fire. However, the reality is that other heat sources such as boilers, engines, and incandescent light bulbs often generate false alarms, so their utilization is not so high in real environments. Detecting fires by perceiving smoke generation can also be one way. However, when smoke is sufficiently detectable, it is not appropriate for early stage fire detection because it means that the fire has already reached a high level. AIM-fire is a solution for remote detection of fire from the initial stage by detecting CO or CO2 gas generated at the fire site.

Fire Detection Using Mid-Wavelength Infrared Camera

If we can detect CO and CO2 gas from the initial stage of a fire, we can detect a fire at an early stage. The problem is that these gases are colorless, odorless, and tasteless. Using a mid-wavelength infrared camera, we can photograph the presence of the gas. This takes advantage of the infrared camera’s blackbody radiation imaging function and the property that light transmittance decreases at 4.5 µm for CO and 4.2 µm for CO2. When viewed in succession of these infrared images, smoke appears to be present at the point where the gas is present. AIM-fire identifies these features from the infrared image set and detects a fire based on the size or density of the gas features. In addition, due to the characteristics of the mid-wavelength infrared camera, fire detection is possible both during the day and at night.

Fire Monitoring System in a Large Space

Fire detection sensors are generally used to detect fires indoors or at close distances. However, it is difficult to detect a fire by them when it is outdoors or indoors in a large space. Since it is based on the detection of CO and CO2 from the initial stage, we can ensure the reliability of the fire detection results.
