DE102006050902A1 - Warning system for early detection of flue gas, has active system to collect surrounding parameters, and alarm device to deliver corresponding alarm upon processing of data such that inference is shortly obtained before break-through of gas - Google Patents

Abstract

The system has an active system to collect surrounding parameters e.g. temperature, infrared portion, air pressure, and oxygen or carbon monoxide contents. An alarm device delivers a corresponding acoustic or optical alarm upon processing of data such that inference is shortly obtained before break-through of flue gas. The parameters are conveyed to a microprocessor that compares the parameters with a characteristic diagram of a typical symptom e.g. high room temperature and infrared portion, drop in air pressure, less oxygen content, or high carbon monoxide content, of gas break-through.

Description

at Building fires begin the objects contained therein outgas due to the enormous heat. This flue gas collects first under the ceiling and forms a more or less thick Gasteppich. In addition, gas formations are caused by incomplete burns, which also collect in the fire object. Reached the gas mixture an ignitable concentration, it comes to the sudden ignition, the dreaded flash over. Another even more dangerous Variant is the so-called back draft, which arises when actually too rich flue gas mixtures suddenly come into contact with oxygen. Even then, it comes to the explosive combustion of the flue gas, causing the emergency services the fire department in the highest Danger.

To current status the emergency services Estimate the situation only by observation by pointing to tongues of fire be careful under the cover or intensive soot deposits. Noticeable information about the Oxygen content or carbon monoxide content is the task forces Of course not using heavy respiratory protection. Likewise the ambient temperature, a very important parameter, due the today usual high quality Protective clothing, can not be judged fast enough. Not infrequently firefighters with burnt protective clothing have returned from the operation, without first noticing something.

task The invention is therefore to provide a system which the forces carry with you and which you as soon as possible before an impending Smoke gas ignition warns. This object is achieved with a described in the main claim 1 Warning system for early detection of flue gas ignition solved. Further leading designs are the ancillary claims refer to.

When solution becomes a device indicated, which carries the operational force and which single, several or all parameters of the environment such as temperature, Brightness, infrared, air pressure, sound attenuation, the content of oxygen, Carbon monoxide or any other gases detected.

The Capture is sensory or with an active system that is called, Waves are emitted in arbitrary frequencies and a receiver is evaluated, how the environment affects the propagation, attenuation, runtime, or reflection of the waves.

The data obtained in this way are compared with respect to their absolute values, relative values, Delta values or due to the constellation of data to each other analog or digitally processed so that conclusions about an imminent by firing be drawn by flue gases.

The analog or digital data is preferably a microprocessor supplied which covered the Compare parameters with a map. The map includes the typical symptoms of an imminent ignition of flue gases. For example it's an extremely high room temperature, a flickering light effect, a high infrared content, a drop in air pressure relative to the values outside of the fire object, a muted one Sound transmission, too low an oxygen content or too high a carbon monoxide content.

Should the measured parameters coincide with the map or this even exceed, gives the device an audible or visual alarm. That way the emergency services to immediate withdrawal causes or if that is no longer possible is, at least prepared, as flat as possible on the ground to take cover.

optional can the device the alarm or the measured values to other devices pass.
