Warn- und überwachungsgerät für die Beleuchtungsanlage in Kraftfahrzeugen. Warning and monitoring device for the lighting system in motor vehicles.
Die Erfindung betrifft ein xeß- und Meldegerät, fest eingebaut im Armaturenbrett von Kraftfahrzeugen.The invention relates to an xeß- and signaling device, permanently installed in the Automobile dashboards.
Der Zweck besteht im wesentlichen darin, daß Krlftfahr= zeuge durch die Anlage verkehrssicherer gemacht werden.The main purpose is to get motor vehicles through the system can be made more roadworthy.
Bei der automatischen Überprüfung wird ein Ausfall einzelner Leuchten frühzeitig gemeldet, und zwar auch tagsüber bei nicht eingeschalteter Beleuchtung.The automatic check detects a failure of individual luminaires reported in good time, even during the day when the lights are not switched on.
Außerdem wird die Überprüfung der Funktionsfähigkeit der Bremsleuchten ohne fremde Hilfe ermöglicht.It also checks the functionality of the brake lights made possible without outside help.
Bisher war es üblich die Beleuchtungsanlage zu über= prüfen, indem jede Leuchte eingeschaltet wurde. Bei den Bremsleuchten betätigte eine Person das Bremspedal und eine zweite Eerson bestätigte die Funktionsfähigkeit, Andere methoden wie zum Beispiel die Überwachung der Leuchten durch Fotozellen oder Fotowiderständen scheiter= te an dem zu betreibenden Aufwand.So far it was common to check the lighting system by every lamp was switched on. One person operated the brake lights Brake pedal and a second Eerson confirmed the functionality, Other methods such as the monitoring of the lights by photocells or photo resistors failed because of the effort to be made.
Der Erfindung liegt die Aufgabe zugrunde, an zentraler Stelle, ohne Verlegung von Leßleitungen zu den einzel= nen Leuchten mit geringem Aufwand eine einwandfrei Überprüfung sämtlicher Leuchten vorzunehmen. Die meß= leitungen werden nur innerhalb des Armaturenbrettes zu den einzelnen Schaltern geführt.The invention is based on the object at a central point without Laying of measurement lines to the individual lights with little effort to properly check all lights. The measuring lines are only led to the individual switches within the dashboard.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß jeder Lichtstromkreis im intakten Zustand in Verbindung mit dem eß- und Leldegerät eine abgeglichene Wider= standsbrücke bildet. Vorgesehen sind 6 parallele Wider= standsbrücken. Jede Widerstandsbrücke bildet mit einem Patentansprüche Glühlampen-Schaltkreis, wobei mehrere Glühlampen parallel geschaltet sein können, eine abgeglichene Spannung, die an einem Spannungsmesser zu Null Volt kompensiert wird. Zur Vermeidung von gegenseitiger Beeinflussung und zur Vermeidung von Rückströmen sind die einzelnen Meßkreise mit halbleiter Dioden beschaltet. Bei Glühfadenbruch liner Leuchte oder Unterbrechung einer Kabelverbindung ergibt sich eine Fehlermeßspannung, ausgelöst durch den erhöhten Wider= standswert im meßkreis. Bedingt durch die verschie= denen Widerstandswerte der einzelnen Glühlampen er= geben sich unterschiedliche Fehlermeßspannungen, deren Werte dur@h zusätzliches Beschalten von Meß= widerständen (nicht eingezeichnet) fixiert werden können. Anhand der unterschiedlichen Fehlermeßspannung läßt sich auf dem Spannungsmesser ablesen, in welchem Stromkreis der Fehler vorliegt. nntsprechende Be= schriftung der aeßgeräteskala erleichtert die Diagnose.This object is achieved according to the invention in that each lighting circuit in the intact condition in connection with the eating and reporting device a balanced cons = standing bridge forms. 6 parallel resistance bridges are provided. Any resistance bridge forms with one Claims incandescent lamp circuit, wherein several Incandescent lamps can be connected in parallel, a balanced voltage applied to one Voltmeter is compensated to zero volts. To avoid mutual The individual measuring circuits are included to influence and avoid reverse currents semiconductor diodes wired. In the event of a broken filament, the liner lamp or an interruption a cable connection results in an error measurement voltage, triggered by the increased Resistance value in the measuring circuit. Due to the different resistance values of the individual incandescent lamps result in different error measurement voltages, their Values due to additional wiring of measuring resistors (not shown) can be fixed. On the basis of the different error measurement voltage, read on the voltmeter in which circuit the fault is present. appropriate Labeling on the measuring device scale facilitates diagnosis.
tin Ausführungsbeispiel der erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.tin embodiment of the invention is shown in the drawing and is described in more detail below.
ueber die Leitung A erfolgt ein Spannungsimpuls auf di Kleme 1 und gelangt über die nachgeschalteten iderstände und Dioden zu den Klemmen 3 bis 8, die zu den Licht stromkreisen führen.A voltage pulse is sent to terminals 1 and 2 via line A reaches terminals 3 to 8 via the downstream resistors and diodes, which lead to the lighting circuits.
Klemme @ Bremsleuchte, 4 standlicht und Kennzeichen, 5 Abblendlicht, 6 Scheinwerfer, 7 Blinkleuchte rechts, 8 Blinkleuchte links, es können weitere Stromkreise hinzugefügt werden. Bei defektem Lichtstromkreis steigt die Spannung an d1 an und läßt das Relais d1 ansprechen, welches in selbshaltung schaltet, eine .arnleuchte aufleuchten lät und den Spannungsmesser einschaltet. lurch betätigen des Tasters bl wird erneut eine Spannung auf Klemme 1 aufgeschaltet. Die nun auftretende Fehlermeßspannung kann auf dem Span nungsmesser abgelesen werden. Klemme 9 ist Lassepunkt.Terminal @ brake light, 4 parking lights and license plate, 5 low beam, 6 headlights, 7 right flashing light, 8 left flashing light, additional circuits can be used to be added. If the lighting circuit is defective, the voltage at d1 increases and causes relay d1 to respond, which switches to self-holding, a warning light lights up and turns on the voltmeter. by pressing the button A voltage is applied to terminal 1 again. The now occurring error measurement voltage can be read on the voltmeter. Terminal 9 is the release point.
