Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zur Brandbekämpfung, bei dem die Wurfrichtung des Löschmittels automatisch so eingestellt wird, daß dieses auf eine Brandstelle auftrifft.The invention relates to a method for fire fighting, in which the Throwing direction of the extinguishing agent is automatically set so that this strikes a fire.
Es ist bereits aus der Patentanmeldung DE 196 01 282 ein Verfahren bekannt geworden, bei dem der fernbedienbare Werfer mit Hilfe eines IR-Lasers automatisch eingestellt wird.It is already a process from patent application DE 196 01 282 become known, in which the remote-controlled launcher with the help of an IR laser is set automatically.
Bei dem letztgenannten Verfahren werden jeweils verschiedene Meßwerte für Temperatur und Entfernung ermittelt.In the latter method, different measured values for Temperature and distance determined.
Anhand der ermittelten Temperaturmeßwerte wird dann geprüft, ob im Überwachungsbereich ein Brand erkennbar ist. Wird eine Brandstelle erkannt, so werden aus dem/den Entfernungsmeßwert(en) Abstand und Richtung der Brandstelle in bezug auf den Werfer ermittelt und daraus der Soll-Wert für die Werfereinstellung bestimmt.On the basis of the measured temperature values it is then checked whether in Monitoring area a fire is detectable. If a fire is detected, distance and direction of the distance measurement value (s) Fire point determined in relation to the thrower and from this the target value for the Thrower setting determined.
Bei einer bevorzugten Ausführungsform ist die Fernmeßeinrichtung eine Laserentfernungsmeßvorrichtung.In a preferred embodiment, the remote measuring device is a Laser distance measuring device.
Bei einer solchen, an sich bekannten Meß Vorrichtung, erfolgt die Entfernungs messung mittels einer Ablenkeinheit (Scanner) nach der Puls-Laufzeit-Methode. Bei dieser Meßmethode ist der Laserstrahl mit wenigstens zwei Sinusschwin gungen unterschiedlicher Frequenz moduliert, so daß beim Überlagern des ausgesendeten Meßlaserstrahles, mit dem von der Meßstelle reflektierten Lichtes, eine Phasenverschiebung auftritt, die proportional zum Abstand zwischen Laserentfernungsmeßvorrichtung und der Meßstelle ist. In such a known measuring device, the removal takes place measurement by means of a deflection unit (scanner) according to the pulse transit time method. With this measuring method, the laser beam has at least two sine waves gations different frequency modulated so that when superimposing the emitted measuring laser beam, with the reflected from the measuring point Light, a phase shift occurs that is proportional to the distance between the laser distance measuring device and the measuring point.
Nachteilig ist dabei, daß bei starker Rauchentwicklung das Laserentfernungs meßgerät, bei welchem nicht mit gesundheitsschädlichen Strahlen gearbeitet wird, nicht immer in der Lage ist, durch den Rauch hindurchzudringen und die entsprechende Entfernung zu ermitteln. Dieser Nachteil wirkt sich hauptsächlich im mobilen Einsatz aus, bei dem verschiedene mobile Geräte z. B. Löschfahrzeuge, Roboter usw. eingesetzt werden.The disadvantage here is that the laser removal when there is a lot of smoke measuring device in which did not work with harmful radiation is not always able to get through the smoke and determine the corresponding distance. This disadvantage works mainly in mobile use, where various mobile devices e.g. B. fire trucks, robots, etc. are used.
Bei stationärer Verwendung ist die Entfernung des zu schützenden Objektes bekannt. Bei größeren Objekten in diesem Bereich, wo bereits in der Brandentstehungsphase Entfernung gemessen werden kann, wird der gemessene Wert so einprogrammiert, daß der Einstellwinkel des Werfers auch dann nicht beeinträchtigt wird, wenn die Entfernung durch evt. Rauchent wicklung nicht mehr gemessen werden kann.With stationary use, the distance of the object to be protected is known. For larger objects in this area, where already in the Fire development phase distance can be measured, the measured value programmed so that the angle of attack of the projector is not impaired even if the removal is caused by smoke winding can no longer be measured.
Im mobilen Bereich wird zur Lösung dieser Aufgabe vorgeschlagen, daß nur ein einziges IR-Richtungsmeßgerät eingesetzt wird.In the mobile area it is proposed that only a single IR direction measuring device is used.
Die Entfernungs- und Richtungsmeßwerte zur Brandstelle werden dann während der Fahrt ermittelt. Diese Meßwerte nach Fig. 1 dienen zum Ausrichten des Löschmittelwerfers.The distance and direction measurements to the fire site are then determined while driving. These measured values of FIG. 1 are used for aligning the extinguishing agent thrower.
Während der Fahrt bis zur Brandstelle treten in der Regel verschiedene Hin dernisse auf, wie z. B. Bäume oder im Industrie- und Raffineriebereich Gebäude, Behälter, Rohrleitungen usw. wodurch eine geradlinige Fahrt zur Brandstelle nicht möglich ist. As a rule, there are various outings while driving to the fire site on, such as B. trees or in industrial and refinery buildings, Containers, pipelines, etc. making a straight line to the fire site not possible.
Während der Fahrt werden mehrere Messungen mit dem IR-Meßgerät vorge nommen und es entstehen verschiedene Winkel zur Brandstelle BS, wie Fig. 1 zeigt.During the journey, several measurements are taken with the IR measuring device and there are different angles to the fire site BS, as shown in FIG. 1.
Wenn die Löscheinheit LE z. B. von Meßpunkt T1 zu Meßpunkt T2 fährt, entsteht zwischen den Meßlinien C1 und B1 zu BS ein bestimmter Winkel α 1, der im Rechner gespeichert wird. Ebenso entsteht bei der nächsten Messung zwischen den Meßpunkten T2 und T3 zwischen den Meßlinien C2 und B2 zu BS der Winkel α 2.If the extinguishing unit LE z. B. from measuring point T1 to measuring point T2 drives, a certain one is created between the measuring lines C1 and B1 to BS Angle α 1, which is saved in the computer. Likewise, the next one Measurement between measuring points T2 and T3 between measuring lines C2 and B2 to BS the angle α 2.
Wenn die Löscheinheit mit einem Fahrtgeber ausgerüstet wird, dessen Meßergebnisse zwischen den Meßpunkten T1, T2 und T3 durch den Rechner erfasst werden, können die jeweiligen Abstände zur Brandstelle BS ermittelt werden.If the extinguishing unit is equipped with a travel sensor, the Measurement results between the measurement points T1, T2 and T3 by the computer can be recorded, the respective distances to the fire site BS be determined.
Da das IR-Meßgerät im µs-Bereich die Messungen vornimmt, können zahlreiche Messungen während der Fahrt vorgenommen werden.Since the IR measuring device takes the measurements in the µs range, numerous Measurements are made while driving.
Ein weiterer Vorteil dieser Entfernungsmeßmethode ist, daß das IR-Meßgerät durch seine Wärmeempfindlichkeit mehrere brennende oder in Gefahr befindliche Objekte (Kühlstelle KS-A2, B3, C3, α3) während der Fahrt orten kann.Another advantage of this distance measuring method is that the IR measuring device due to its sensitivity to heat, several burning or in danger Objects (refrigeration point KS-A2, B3, C3, α3) can be located while driving.
Dadurch können nicht nur Löschfahrzeuge, die mit mehreren Löschmittelwerfern ausgerüstet sind wirkungsvoller eingesetzt werden, sondern auch der Gesamt einsatz optimaler gestaltet werden.This means that it is not only fire-fighting vehicles that have several fire-extinguishing devices equipped are used more effectively, but also the overall optimal use.
