Abstract
Description
Die Erfindung bezieht sich auf ein Gerät zur Erfassung von Rauchgas-Konzentrationen noch weit unter den gif tigen Bereichen. So dient das Gerät in erster Linie zur Bewahrung eines guten Gesundheitszustandes und nur in zweiter Linie als Warngerät von Rauchgasen.The invention relates to a device for detection of flue gas concentrations still far below the gif areas. The device is primarily used for Preservation of good health and only in second line as a warning device for flue gases.
An den Arbeitsplätzen sind viele Gaswarngeräte vorge schrieben, die die maximale zulässige Arbeitsplatzkon zentration bei toxischen Gasen (MAK-Wert) überwachen, bekannt sind auch Warngeräte für große Konzentrationen von Autoabgasen in Tiefgaragen. Für kleinere Konzen trationen von Autoabgasen aber, wie sie z. B. in fah renden Fahrzeugen oder in Wohnungen auftreten können, wobei normalerweise direkte Lebensgefahr nicht vorhanden ist, sind keine Geräte konzipiert. Ebenso gibt es keine Meß- und Warngeräte für die Messung von Zigarettenrauch, weil Rauch in größeren Konzentrationen auch nicht tödlich ist. Es ist jedoch unumstritten, daß die Einatmung von Zigarettenrauch gesundheitsschädlich und mit sehr großer Wahrscheinlichkeit krebsfördernd ist. Dieser gesundheits schädliche Effekt ist sehr groß bei sogenannten Passiv rauchern, wo der Körper gegen die unregelmäßig auftreten den Belastungen nicht entsprechend reagieren kann.Many gas detectors are featured in the workplaces wrote, which the maximum permissible workplace con monitor the concentration of toxic gases (MAK value), warning devices for large concentrations are also known of car exhaust in underground garages. For smaller concessions trations of car exhaust fumes, however, as z. B. in fah vehicles or in apartments, whereby there is usually no direct danger to life no devices are designed. Likewise, there are none Measuring and warning devices for measuring cigarette smoke, because smoke in higher concentrations is not fatal either is. However, it is not controversial that inhalation of Cigarette smoke harmful to health and very large Probability is cancer-promoting. This health harmful effect is very large with so-called passive smoke where the body against the irregular occur cannot react appropriately to the loads.
Der Erfindung liegt die Aufgabe zugrunde, ein Gerät zu konstruieren, dessen Aufgabe es ist, das vorhandene und das objektive Maß einer Langzeitgefährdung anzuzeigen. Das Gerät besteht aus mehreren Modulen, wobei die Mög lichkeit besteht, alle Module, alle Fühler, Auswerter und Anzeigemodule zusammenzubauen oder einige überflüs sige Module wegzulassen.The invention has for its object to a device construct, whose task it is, the existing and display the objective measure of long-term risk. The device consists of several modules, the poss there is all modules, all sensors, evaluators and assemble display modules or overflow some omit some modules.
Die Erfassung von verschiedenen Rauchgasen ist aus der Brand- und Feuermeldetechnik bekannt. Die angewandten Sensoren sind auf den Rauchgas-Partikelteilchen spezi fiziert; meistens mit radioaktiven Quellen gelöst. Diese Erfassung von Rauchgasen ist einmal ziemlich unspezi fisch, zweitens, die radioaktive Quelle für breite An wendung (bei Ausgabe von Handelsgeräten ist unzulässig); deswegen ist unser Lösungsweg, daß wir nicht bei der Rauchbildung feste, schwebende Körperchen nachweisen, sondern verschiedene gasförmige Komponente.The detection of different smoke gases is from the Fire and fire detection technology known. The applied Sensors are special on the flue gas particle fected; mostly solved with radioactive sources. These Smoke gas detection is quite unspecific fish, secondly, the radioactive source for wide range turn (when issuing commercial equipment is not permitted); therefore our solution is that we are not at the Detect smoke, solid, floating bodies, but different gaseous components.
Der Nachweis von diesen verschiedenen gasbildenden Komponenten erfolgt durch chemische Gassensoren, wobei vorzugsweise eine Mehrkomponentensensorlösung vorzuziehen ist. Evidence of these various gas-producing Components are made by chemical gas sensors, whereby preferably a multi-component sensor solution is preferable is.
Die Erfassung der Rauchgas-Konzentration geht durch Sensoren, die außerhalb oder innerhalb des Meßgerätes plaziert sind. Diese Sensoren sind chemische, elektro lytische, Wärmeleitfähigkeits-, Halbleiter- oder Halb leiteroxid optische Fluoreszenz mit Lichtabsorption- Sensoren. Einige Sensoren sind Breitbandsensoren, also auf eine Reihe von Verbindungen, einige sind selektiv oder mit sehr geringer Querempfindlichkeit und nur so auf einige Komponente, wie z. B. Kohlenmonoxid, Kohlen dioxid oder Wasserstoff empfindlich. Da Zigarettenrauch oder Autoabgasrauch aus sehr vielen Komponenten besteht, ist es vorteilhaft, möglichst viele Komponente (Kohlen monoxid, Kohlendioxid, Wasserstoff, Staubpartikel- Aerosole, dehnbare Anteile usw.) getrennt zu erfassen, wobei das ganze Signal einiger Breitbandsensoren, die auf gleichzeitig viele Komponente empfindlich sind, (Halblei teroxid-Sensor) auch von Interesse ist.The detection of the flue gas concentration goes through Sensors outside or inside the measuring device are placed. These sensors are chemical, electrical lytic, thermal conductivity, semiconductor or semi conductor oxide optical fluorescence with light absorption Sensors. Some sensors are broadband sensors, so on a number of connections, some are selective or with very little cross sensitivity and just like that on some component, such as B. carbon monoxide, carbon sensitive to dioxide or hydrogen. Because cigarette smoke or car exhaust smoke consists of many components, it is advantageous to use as many components (coals monoxide, carbon dioxide, hydrogen, dust particles Detect aerosols, stretchable components etc.) separately, being the whole signal of some broadband sensors that are on many components are sensitive at the same time (half lead teroxide sensor) is also of interest.
Die Signalauswertung der einzelnen Sensoren ergibt das Maß der Rauchgaskonzentration. Bei einfacher Ausführung ist es jedoch möglich, wenige oder sogar nur einen ein zigen Sensor zu benützen. Das Signal der Sensoren wird einer Auswerteeinheit zugeführt. Diese Auswerteeinheit wird durch einen Mikroprozessor ausgeführt oder durch einfache Analogschaltungen realisiert. Es ist durchaus möglich, die gemessene Konzentration in % oder in Kon zentrationswerten auszugeben, aber es ist sinnvoller, konkrete Werte anzugeben. So ist es bei dem konstruierten Gerät ein Modul, das die Rauchgaskonzentration mit einer 100%igen Konzentration, wie z. B. bei Zigarettenrauch, vergleichen kann. Es vergleicht, wieviel Teile in % der gerade gemessenen Zigarettenrauch-Konzentration zu einer 100%igen von einem Raucher eingeatmeten Rauch ent spricht.The signal evaluation of the individual sensors shows that Measure of the flue gas concentration. With simple execution however, it is possible to have a few or even just one umpteen sensor to use. The signal from the sensors will fed to an evaluation unit. This evaluation unit is executed by a microprocessor or by simple analog circuits implemented. It is quite possible to measure the measured concentration in% or in con center values, but it makes more sense to give concrete values. So it is with the constructed Device is a module that measures the flue gas concentration with a 100% concentration, such as B. with cigarette smoke, can compare. It compares how many parts in% of the just measured cigarette smoke concentration to a 100% smoke inhaled by a smoker speaks.
Dieses prozentuale Ergebnis kann in einer Leuchttafel oder durch Sprachausgabe von vorher programmierten Sprachtexten oder durch Magnettonabruf ausgegeben werden. Es ist weiterhin möglich, aus diesem errechneten, pro zentualem Wert die Dauer auszurechnen, bis man bei der aktuellen Konzentration soviel Zigaretten- oder Pfeifen rauch eingeatmet hat, als würde man eine Zigarette oder Pfeile selber rauchen. Diese Information ist sehr vor teilhaft für Zwangspassivraucher, die durch die Umgebung gezwungen sind, Zigaretten- oder Pfeifenrauch einzuatmen. Nach einem bestimmten Zeitraum haben sie die gleiche Belastung, als würden sie selber Zigaretten oder Pfeifen rauchen. This percentage result can be seen in a light panel or by voice output from previously programmed Language texts or be issued by magnetic sound retrieval. It is still possible to calculate from this, per to calculate the duration until you get to the current concentration so much cigarette or pipe inhaled smoke as if you were smoking a cigarette or Smoke arrows yourself. This information is very before partial for compulsive passive smokers who pass through the area are forced to inhale cigarette or pipe smoke. After a certain period of time, they have the same Burden as if they were smoking cigarettes or pipes themselves smoke.
Zu der Vergleichseinheit kommt auch das Signal des Sauerstoffsensors, der Sauerstoffmangel anzeigt, wobei dieser Mangel besonders bei Auspuffgasen sehr gefährlich sein kann. In der Vergleichseinheit sind feste Werte eingespeichert, wo nach Erreichen dieser Werte ent sprechende Steuersignale ausgelöst werden. Diese Steuer signale können zu Belüftungs- oder Klimaanlagen gekoppelt werden, die eine starke Zwangsbelüftung verursachen, oder sie können einen persönlichen kleinen Ventilator oder eine Filtereinheit einschaltet, die die Person mit frischer oder filtrierter Luft versorgt oder auffälligere Informationsvorrichtungen steuern, durch Sprachausgabe oder durch optische Warnanzeigen (Verbotssignale, lesbaren Text durch beleutetes Leuchtband). Vorteilhaft ist die Sprachausgabe, die vorher in Memorychips programmiert worden ist, oder bei Abruf entsprechender, in Eproms festgespeichert oder in RAMs-Bauelementen gespeicherter Texte oder durch Betätigung und Einschaltung von Ton bandgeräten.The signal of the Oxygen sensor that indicates lack of oxygen, whereby this deficiency is very dangerous, especially with exhaust gases can be. There are fixed values in the comparison unit stored where, after reaching these values speaking control signals are triggered. This tax signals can be coupled to ventilation or air conditioning systems that cause strong forced ventilation, or they can have a personal little fan or turns on a filter unit that the person with fresh or filtered air or more conspicuous Control information devices through voice output or by visual warning signs (prohibition signals, readable Text by illuminated strip). That is advantageous Narrator that was previously programmed into memory chips has been, or when retrieved, in Eproms stored permanently or stored in RAM components Texts or by activating and switching on sound tape devices.
Mit der Vergleichseinheit ist eine Anzeigeninformations einheit verkoppelt. Diese Informationseinheit kann eine selbständige tragbare Informationsvorrichtung sein, oder zu einem fest installierten System angeschlossen werden. Die einfachste Informationseinheit besteht aus einer oder mehreren Leuchtdioden oder ist mit verschiedenen Symbolen gekennzeichnet.With the comparison unit is a display information unit coupled. This information unit can be a stand-alone portable information device, or connected to a permanently installed system. The simplest unit of information consists of an or several LEDs or is with different symbols featured.
In den Zeichnungen 1 und 2 ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt:In drawings 1 and 2, the subject matter of the invention shown in one embodiment:
Kleines, tragbares Gerät für die Bestimmung von Zigarettenrauch. Das Gerät ist mit einem Sensor (1) (vorzugsweise mit einem Schmalband-elektrochemischen Sensor, Kohlenmonoxid und Wasserstoff) ausgestattet. Aber es können andere Sensoren, wie z. B. Breitband- Zinnoxid-Sensoren sein. Der Sensor wird direkt für Zigarettenrauch geeicht.Small, portable device for the determination of cigarette smoke. The device is equipped with a sensor ( 1 ) (preferably with a narrowband electrochemical sensor, carbon monoxide and hydrogen). But other sensors, such as. B. broadband tin oxide sensors. The sensor is directly calibrated for cigarette smoke.
Das Signal von dem elektrischen Sensor wird durch eine bekannte potentiostatische Schaltung (2) verstärkt. Das verstärkte Signal wird zu einer Leuchtdiodenkettensteu erungsschaltung (3) zugeführt und andererseits dieses Signal zu einer Vergleichsschaltung zugeleitet. Das Maß der aktuellen Rauchgaskonzentration wird durch die Leuchtdiodenketten (4) angezeigt, wobei die erste Leuchtdiode grün ist, die reine Luft anzeigt. Die weiteren Leuchtdioden sind gelb und an der oberen Seite die Leuchtdiodenketten sind rot, die starke Rauchgas-Kon zentration andeuten.The signal from the electrical sensor is amplified by a known potentiostatic circuit ( 2 ). The amplified signal is fed to a light-emitting diode chain control circuit ( 3 ) and, on the other hand, this signal is fed to a comparison circuit. The measure of the current smoke gas concentration is indicated by the LED chains ( 4 ), whereby the first LED is green, which indicates clean air. The other light-emitting diodes are yellow and the light-emitting diode chains on the upper side are red, which indicate a strong flue gas concentration.
In dem zweiten Anzeigefeld (5) sind kleine Fenster mit einer oder mehreren brennenden Zigarettensymbolen ver sehen, wobei hinter diesen Fenstern die entsprechende Komperatorschaltung beim Erreichen des entsprechenden Wertes kleine Lampen oder LED-Dioden einschaltet. Diese Werte werden aus der aktuellen Rauchgas-Konzentration errechnet. Die Fenster zeigen an, wieviel Zigaretten man bei der aktuellen Rauchgas-Konzentration und 8stündiger Einatmung rauchen würde. So z. B. wenn das Symbol mit zwei Zigaretten aufleuchtet, bedeutet das, daß man bei der aktuellen Konzentration und 8stündiger Einatmung zwei Zigaretten rauchen würde.In the second display field ( 5 ) small windows with one or more burning cigarette symbols are seen, behind which windows the corresponding comparator circuit turns on small lamps or LED diodes when the corresponding value is reached. These values are calculated from the current flue gas concentration. The windows show how much cigarettes you would smoke with the current smoke gas concentration and 8 hours of inhalation. So z. B. if the symbol lights up with two cigarettes, it means that one would smoke two cigarettes at the current concentration and 8 hours of inhalation.
An der rechten Seite des Gerätes ist ein Lautsprecher (6) untergebracht, der mit einer Speicherschaltung in Verbin dung steht. An dem Gerät sind zwei weitere Knöpfe und ein Mikrophon (7) (8) befestigt, die für die Steuerung dieser Sprachwiedergabeschaltung notwendig sind.On the right side of the device, a speaker ( 6 ) is housed, which is connected to a memory circuit. Two further buttons and a microphone ( 7 ) ( 8 ), which are necessary for controlling this voice reproduction circuit, are attached to the device.
Durch das Einschalten des Gerätes, durch das Drücken der Sprachspeichertastatur (7) kann man einen bestimmten Text mit der Sprachwiedergabebeschaltung einspeichern. Der Text kann mit dem Mikrophon (8) aufgenommen werden. Entspre chende LED-Anzeigen (9) zeigen, daß das Gerät jetzt gera de im Sprachspeicherzustand ist. Es können verschiedene Texte gespeichert werden, z. B. "Bitte hören Sie mit dem Rauchen auf! Es gefährdet unsere Gesundheit." Oder andere witzige Texte wie: "Bitte höre mit dem Rauchen auf! Du wolltest Dir doch das Rauchen abgewöhnen." By switching on the device, by pressing the voice memory keyboard ( 7 ) you can save a certain text with the voice playback circuit. The text can be recorded with the microphone ( 8 ). Corresponding LED displays ( 9 ) show that the device is now just de voice memory. Different texts can be saved, e.g. B. "Please stop smoking! It is dangerous to our health." Or other funny texts like: "Please stop smoking! You wanted to stop smoking."
An der vorderen Seite des Gerätes befindet sich ein weiterer Knopf, mit diesem Knopf kann man auswählen, bei welcher Zigarettenrauchkonzentration diese Sprachwieder gabe eingeschaltet und die Rückgabe des Textes aus gelöst werden soll.There is a on the front of the device another button, with this button you can choose at what cigarette smoke concentration this speech repeats I switched on and returned the text should be solved.
