Abstract
Description
Die Erfindung betrifft eine selbsttätig arbeitende Vorrichtung zur Kontrolle der Durchsichtigkeit von Scheiben, insbesondere Windschutzscheiben in Fahrzeugen, bestehend aus einem Strahlungssender und einem Strahlungsempfänger sowie einer Auswertschaltung.The invention relates to an automatically operating device for checking the transparency of panes, in particular windscreens in vehicles a radiation transmitter and a radiation receiver and an evaluation circuit.
Die Sicherheit eines Fahrzeuges wird durch verschmutzte, verkratzte und gealterte Windschutzscheiben erheblich beeinträchtigt. Dem Fahrzeugfahrer fällt oftmals die Sichtverschlechterung durch Abnutzung einer Windschutzscheibe in Form von meist sehr feinen Kratzern und in Form von Alterungen nicht auf, da er sich über Monate und Jahre an diesen Zustand seiner Windschutzscheibe gewöhnt. Bei langen Fahrten in trockenem Wetter fällt dem Fahrer aber auch oftmals nicht auf, daß sich auf seiner Windschutzscheibe ein die Sicht verschlechternder Staubfilm absetzt, weil der Fahrer sich langsam an diesen Staubfilm gewöhnt. Trotzdem kann in entscheidenden Gefahrenmomenten die Verschlechterung der Durchsichtigkeit der Windschutzscheibe Anlaß zu Überfällen werden. The safety of a vehicle is affected by dirty, scratched and aged windshields significantly impaired. This often falls to the vehicle driver Visibility deterioration due to wear of a windshield in the form of mostly very fine scratches and in Form of aging does not show up since it lasts for months and used to this windshield for years. During long journeys in dry weather, this is not the case But drivers often do not rely on that on his Windshield a dust film impairing the view discontinues because the driver slowly adopts these Dust film used. Nevertheless, there can be crucial moments of danger the deterioration in transparency the windshield will give rise to raids.
Durch eigene Entwicklungen geschaffene Scheibenkontrollvorrichtungen können diese Gefahren vermeiden. Sie stellen die Durchsichtigkeit von Scheiben fest und lösen einen Reinigungs- und/oder Warnvorgang aus, der schließlich auch das Ende der Lebensdauer einer Windschutzscheibe anzeigt.Disc control devices created by our own developments can avoid these dangers. they determine the transparency of windows and loosen a cleaning and / or warning process that eventually also the end of the life of a windshield displays.
Die Scheibenkontrollvorrichtung der deutschen Patentanmeldung P 35 15 409.8 nutzt das Licht der Umgebung, um die Durchsichtigkeit einer Scheibe festzustellen, indem sie auf der der Lichtquelle abgewandten Seite der Scheibe Strahlungsempfänger anordnet und die von diesen empfangenen Strahlungswerte mit den von einem Strahlungsempfänger hinter einer Idealscheibe angeordneten Strahlungsempfänger vergleicht. Um unabhängig von dem Umgebungslicht zu werden, ist nach der deutschen Patentanmeldung P 35 21 686.7 eine besondere Strahlungsquelle vorgesehen, die die Windschutzscheibe eines Fahrzeuges durchstrahlt, hinter der Meßaufnehmer angeordnet sind. Einen anderen Weg geht die ebenfalls eigene Entwicklung nach der deutschen Patentanmeldung P 35 21 739.1, bei der der Verschmutzungsgrad und der Abnutzungsgrad einer Scheibe durch die Änderung der elektrischen Leitfähigkeit festgestellt wird.The disk control device of the German patent application P 35 15 409.8 uses the light of the environment to create the Determine transparency of a pane by: on the side of the pane facing away from the light source Arrays radiation receivers and those received by them Radiation values with those from a radiation receiver radiation receiver arranged behind an ideal pane compares. To become independent of the ambient light, is a according to German patent application P 35 21 686.7 special radiation source provided that the windshield of a vehicle shines through, behind the sensor are arranged. There is another way too own development after the German patent application P 35 21 739.1, where the degree of pollution and the Degree of wear of a disc by changing the electrical Conductivity is determined.
Es ist die Aufgabe der vorliegenden Erfindung, eine weitere Möglichkeit zur Feststellung des Verschmutzungs- und/oder Abnutzungsgrades einer Scheibe zu schaffen, und zwar durch Messung der Reflektion von Streulicht, welches von Verschmutzungen und/oder Abnutzungen auf der Oberfläche der zu kontrollierenden Scheibe ausgeht.It is the object of the present invention, another Possibility to determine the pollution and / or To create a degree of wear of a disc, namely by Measurement of the reflection of stray light, which of dirt and / or wear on the surface of the disc to be checked.
Die Erfindung besteht darin, daß der Strahlungssender und der Strahlungsempfänger vor oder hinter oder in der zu kontrollierenden Scheibe untergebracht sind, und daß der Strahlungssender und der Strahlungsempfänger durch eine Blende voneinander getrennt sind, so daß der Strahlungsempfänger nicht direkt vom Strahlungssender Strahlung aufnehmen kann.The invention is that the radiation transmitter and the radiation receiver in front of or behind or in the too controlling disc are housed, and that the Radiation transmitter and the radiation receiver through a Aperture are separated from each other, so that the radiation receiver not directly from the radiation transmitter radiation can record.
Mit dieser Anordnung läßt sich der Verschmutzungs- und/oder Abnutzungsgrad einer Scheibe dadurch feststellen, daß mit zunehmendem Verschmutzungs- und/oder Abnutzungsgrad mehr Strahlung vom Sender auf den Empfänger fällt, da von den Verschmutzungen und/oder Abnutzungen Streustrahlung ausgeht, die allein vom Empfänger gemessen wird.With this arrangement, the pollution and / or Determine the degree of wear of a disc by using increasing degree of pollution and / or wear Radiation from the transmitter falls on the receiver because of the Soiling and / or wear is scattered radiation, which is measured by the receiver alone.
Zweckmäßig ist es, wenn als Strahlung eine Infrarotstrahlung benutzt wird.It is useful if the radiation is infrared radiation is used.
Vorteilhaft ist es, wenn Strahlungssender und Strahlungsempfänger in einem gemeinsamen flachen Gehäuse untergebracht sind. Dann läßt sich die Vorrichtung als eine außerordentlich kleine Baueinheit gestalten, die leicht in oder an der Windschutzscheibe anbringbar ist.It is advantageous if radiation transmitters and radiation receivers housed in a common flat housing are. Then the device can be used as one design extraordinarily small unit that is light is attachable in or on the windshield.
Vorteilhaft ist es, wenn die Blende senkrecht zur Ebene der Windschutzscheibe angeordnet ist, um nicht Stellen einer bevorzugten Reflektion von Streustrahlung zu schaffen.It is advantageous if the diaphragm is perpendicular to the plane of the Windshield is arranged so as not to place one to create preferred reflection of scattered radiation.
Für den Bau und die Anwendung dieses Sender/Blende/Empfänger- Aggregates ist es vorteilhaft, wenn das Gehäuse nur eine strahlungsdurchlässige Seite aufweist, während im übrigen die Gehäusewandungen strahlungsundurchlässig sind. Auf diese Weise läßt sich feststellen, welche Streustrahlung von einer einzigen Oberfläche der zu kontrollierenden Scheibe ausgeht. Es ist vorteilhaft, wenn mehrere derartige Aggregate die Kontrolle der Scheibe übernehmen. Man kann dann feststellen, ob die äußere oder die innere Oberfläche der Windschutzscheibe verschmutzt und/oder abgenutzt sind. Denn es wird meist vermutet, daß nur die äußere Oberfläche der Windschutzscheibe einer Verschmutzung und einer Abnutzung unterliegen, das aber ist nicht der Fall, auch die innere Oberfläche einer Windschutzscheibe eines Fahrzeuges unterliegen diesen Verschmutzungen und/oder Abnutzungen, z. B. durch Tabakrauch u. a.For the construction and use of this transmitter / cover / receiver Aggregates, it is advantageous if the housing only one has radiation-permeable side, while the rest the housing walls are opaque to radiation. On this way it can be determined which scattered radiation from a single surface to be controlled Disc runs out. It is advantageous if several such Units take control of the disc. One can then determine whether the outer or inner surface the windshield is dirty and / or worn. Because it is usually assumed that only the outer surface the windshield of pollution and wear subject, but that's not the case, too the inner surface of a windshield of a vehicle are subject to this contamination and / or wear, e.g. B. by tobacco smoke u. a.
Vorteilhaft ist es, wenn das Gehäuse aus einer Platte besteht, auf der senkrecht die Blende angeordnet ist, zu der beidseits einerseits der Strahlungssender, andererseits der Strahlungsempfänger angeordnet ist, um die herum Teile der Auswertschaltung angeordnet sind. Auf diese Weise wird eine günstige, leicht herstellbare Bauform erzielt.It is advantageous if the housing consists of a plate, on which the diaphragm is arranged perpendicular to the the radiation transmitter on both sides, on the other the radiation receiver is arranged around the parts the evaluation circuit are arranged. That way achieved a favorable, easily manufactured design.
Vorteilhaft ist es weiter, wenn in dem Gehäuse, vorzugsweise ringsum das Aggregat Strahlungssender/Blende/ Strahlungsempfänger, mindestens eine Photozelle und/oder eine Speicherzelle und/oder eine Impulserzeugungsschaltung für die Pulsung des Senders und/oder die Auswertschaltung oder Teile der Auswertschaltung angeordnet sind. Auf diese Weise wird eine Baueinheit geschaffen, die völlig unabhängig vom elektrischen Bordversorgungsnetz eines Fahrzeuges zu arbeiten im Stande ist und mit außerordentlich wenig Energie auskommt, Energie, die sich mit Hilfe geeigneter Solarzellen aus der Umgebung erhalten läßt. Die Größe eines derartigen Aggregates kann die Flächenausdehnung einer kleinen bis mittelgroßen Münze haben und braucht auch nicht dicker als eine solche Münze zu sein, sie kann sogar flacher aufgebaut werden.It is also advantageous if in the housing, preferably all around the unit radiation transmitter / aperture / Radiation receiver, at least one photocell and / or a memory cell and / or a pulse generation circuit for the pulsing of the transmitter and / or the evaluation circuit or parts of the evaluation circuit are arranged. To this In this way, a structural unit is created that is completely independent from the electrical on-board supply network of a vehicle is able to work and with extremely little Energy gets by, energy that can be used with the help of appropriate Preserves solar cells from the environment. The size Such an aggregate can extend the area of a have small to medium-sized coins and do not need them being thicker than such a coin, it can even be flatter being constructed.
Um diese Vorrichtung völlig ohne jeden Anschluß in das Innere einer Windschutzscheibe einbauen zu können, ist es zweckmäßig, wenn ein weiterer Strahlungssender in dem Gehäuse vorgesehen ist, der an den Ausgang des Strahlungsempfängers unter Zwischenschaltung zumindest eines Teiles der Auswertschaltung angeschlossen ist. Mit diesem weiteren Strahlungssender, z. B. einem Infrarotsender, werden einem im Inneren des Fahrzeuges, d. h. außerhalb der Windschutzscheibe angeordneten Empfänger Impulse zugesandt, mit denen eine Steuerschaltung für den Einsatz von Scheibenwischern und/oder einer Warnanlage gespeist werden.To this device completely without any connection in the It is possible to install the inside of a windshield useful if another radiation transmitter in the housing is provided at the output of the radiation receiver with the interposition of at least one part the evaluation circuit is connected. With this further Radiation transmitter, e.g. B. an infrared transmitter, one inside the vehicle, d. H. outside the windshield arranged receivers sent pulses with which a control circuit for the use of windshield wipers and / or a warning system.
Dabei ist es zweckmäßig, wenn der weitere Strahlungssender hinter einer kleinen strahlungsdurchlässigen Stelle einer strahlungsundurchlässigen Wand des Gehäuses angeordnet ist.It is expedient if the further radiation transmitter behind a small radiolucent area radiation-impermeable wall of the housing is arranged.
Das Wesen der vorliegenden Erfindung ist nachstehend anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispieles näher erläutert. Es zeigen:The essence of the present invention is shown below an embodiment shown schematically in the drawing explained in more detail. Show it:
Fig. 1 eine Ansicht einer Windschutzscheibe, die mit den Kontrollvorrichtungen ausgestattet ist, Fig. 1 is a view of a windshield, which is equipped with the control devices,
Fig. 2 in starker Vergrößerung eine Ansicht einer Kontrollvorrichtung,2 shows a view of a control device in high magnification,
Fig. 3 in starker Vergrößerung einen Schnitt durch einen Teil einer Windschutzscheibe, in die die Kontrollvorrichtung eingebaut ist, Fig. 3 in a greatly enlarged section through a part of a windshield, in which the control device is installed,
Fig. 4 ein Schaltbild der Teile der Kontrollvorrichtung. Fig. 4 is a circuit diagram of the parts of the control device.
An der Windschutzscheibe 1 ist ein Scheibenwischer 2 angeordnet, dessen Wischbahn von gestrichelt gezeichneten Linien eingegrenzt ist. Hinter dieser gewischten Fläche befinden sich mehrere Kontrollvorrichtungen 3, die außerhalb des Sichtbereiches des Fahrers angeordnet sind, sich aber hinter einer vom Scheibenwischer 2 gewischten Stelle der Oberfläche der Windschutzscheibe befinden.A windshield wiper 2 is arranged on the windshield 1 , the wiper track being delimited by lines drawn in broken lines. Behind this wiped surface there are several control devices 3 , which are arranged outside the driver's field of vision, but are located behind a point on the surface of the windshield wiped by the wiper 2 .
Die Teile der Kontrollvorrichtung und ihre Anordnung sind in starker Vergrößerung dargestellt: Der Strahlungssender 4 und der Strahlungsempfänger 5 sind durch die Blende 6 voneinander getrennt, aber auf einer gemeinsamen Grundplatte 7 aufgebaut. Diese Grundplatte 7 besteht zweckmäßigerweise aus einem undurchsichtigen Material. Sie bildet einen Teil des Gehäuses der Kontrollvorrichtung. Ringsum das Aggregat Strahlungssender 4/Blende 6/ Stahlungsempfänger 5 sind Solarzellen 8 angeordnet, die von ihnen empfangene Lichtenergie in elektrische Energie wandeln, die einer Speicherzelle 9 zugeführt wird. Diese Speicherzelle ist nicht unbedingt notwendig, sie ist aber zweckmäßig, damit die Kontrolle des Scheibenzustandes auch in der Nacht erfolgen kann. - Diese Solarzellen 8 bilden einen weiteren Teil des Gehäuses, in welchem das Aggregat Strahlungssender 4/Blende 6/ Strahlungsempfänger 5 untergebracht sind. Auf der der Grundplatte 7 gegenüberliegenden Seite kann eine durchsichtige Abdeckplatte untergebracht sein, die aber nicht unbedingt notwendig ist.The parts of the control device and their arrangement are shown in a large magnification: the radiation transmitter 4 and the radiation receiver 5 are separated from one another by the diaphragm 6 , but are built on a common base plate 7 . This base plate 7 suitably consists of an opaque material. It forms part of the housing of the control device. Around the aggregate radiation transmitter 4 / aperture 6 / radiation receiver 5 there are arranged solar cells 8 which convert the light energy received by them into electrical energy which is fed to a storage cell 9 . This memory cell is not absolutely necessary, but it is useful so that the condition of the pane can also be checked at night. - These solar cells 8 form a further part of the housing in which the aggregate radiation transmitter 4 / aperture 6 / radiation receiver 5 are accommodated. A transparent cover plate can be accommodated on the side opposite the base plate 7 , but this is not absolutely necessary.
Auf der Grundplatte 7 sind dann weiter die Solarzelle 8 und eine Auswertschaltung 10 untergebracht. Wie man aus Fig. 3 entnehmen kann, läßt sich diese ganze Kontrollvorrichtung sehr flach aufbauen, so daß sie zwischen den beiden Scheibenelementen einer aus Sicherheitsglas hergestellten Windschutzscheibe unterbringbar ist.The solar cell 8 and an evaluation circuit 10 are then further accommodated on the base plate 7 . As can be seen from Fig. 3, this entire control device can be built very flat, so that it can be accommodated between the two pane elements of a windshield made of safety glass.
Aus Fig. 4 ist die elektrische Schaltung ersichtlich, in
der die einzelnen Teile der Kontrollvorrichtung geschaltet
sind:
Von den Solarzellen 8 wird eine Speicherzelle 9 gespeist.
Solarzellen 8 und Speicherzelle 9 bilden das Stromversorgungsaggregat
der Kontrollvorrichtung. Die Solarzellen 8
und die Speicherzelle 9 bilden das Stromversorgungsaggregat
der Kontrollvorrichtung. Mit diesem Stromversorgungsaggregat
wird ein Impulserzeuger 12 versorgt, der seinerseits den
Strahlungssender 4 mit Strom versorgt und ihn gepulst
Strahlungsimpulse aussenden läßt. Mit dem Stromversorgungsaggregat
8, 9 wird auch die dem Strahlungsempfänger 5
nachgeschaltete Auswertschaltung 13 mit Strom versorgt, die
mit ihrem Ausgang an den Eingang eines weiteren Strahlungssenders
11 angeschlossen ist, der seinerseits ebenfalls aus
der Stromversorgung 8, 9 gespeist ist. Dieser weitere Sender
sendet Strahlungsimpulse an einen weiteren Empfänger 14,
dem die Steuerschaltung 15 nachgeschaltet ist, an die einerseits
die Warnvorrichtung 16 über eine weitere Auswertvorrichtung
17 angeschlossen ist, die unter bestimmten vorgegebenen
Bedingungen die Warnvorrichtung in Tätigkeit
setzt. Andererseits ist an die Steuerschaltung 15 die
Schaltung 18 für die Wischerbetätigung angeschaltet.
From Fig. 4, the electrical circuitry can be seen, in which the individual parts of the control device are connected:
A memory cell 9 is fed by the solar cells 8 . Solar cells 8 and storage cell 9 form the power supply unit of the control device. The solar cells 8 and the storage cell 9 form the power supply unit of the control device. A pulse generator 12 is supplied with this power supply unit, which in turn supplies the radiation transmitter 4 with current and allows it to emit radiation pulses in a pulsed manner. The power supply unit 8 , 9 also supplies the evaluation circuit 13 connected downstream of the radiation receiver 5 with its output connected to the input of a further radiation transmitter 11 , which in turn is also fed from the power supply 8, 9 . This further transmitter sends radiation pulses to a further receiver 14 , to which the control circuit 15 is connected, to which on the one hand the warning device 16 is connected via a further evaluation device 17 which, under certain predetermined conditions, activates the warning device. On the other hand, the circuit 18 for the wiper actuation is connected to the control circuit 15 .
