Background technology
Optical detector of fire smoke is also point detector, it is the propagation that the smog generated when utilizing on fire can change light
This fundamental property of characteristic and develop.Absorption and scattering process according to smoke particle to light.Optical detector of fire smoke is divided into
For two kinds of Sun-shading type and astigmatism type.General Point type optical smoke detector belongs to astigmatism type, and line style beam monitor is to use
Sun-shading type.The operation principle of photoelectric smoke detector is that a photosensitive electrode is under laser irradiation electric signal occurs,
When fire hazard aerosol fog covers laser, electrode dead electricity sends out alarm signal.The infrared light-emitting component of Point type optical smoke detector with
It is typically offset design that light-sensitive element (photon acceptor element) detects indoor setting at it.Distance between the two generally exists
20-25mm, under normal smokeless monitored state, quick element does not receive any light, including the light that infrared light-emitting component is sent out.
The light that infrared light-emitting components are sent out when smoke particle enters in detecting chamber is then scattered or be reflected on light-sensitive element by smoke particle,
And when receiving sufficient optical signal, fire alarm is just sent out, this fire detecting method is often referred to as cigarette scattered light method.
After photoelectric smoke detector uses a period of time, monitoring room can enter dust, and the judgement for influencing detector is accurate
Exactness, or even will appear false alarm, current maintenance mode is that photoelectric smoke detector is removed cleaning wiping, then again
Debugging calibration is installed, a large amount of human cost is expended.
