This flashing light warning system shows a voltage converter, which acts as a flyback converter is formed and the converter control from the Vehicle electrical system is supplied. From that of that Voltage converter generated voltage is a Energy storage, which as a high capacity having electrolytic capacitor trained capacitor is charged. This forms with at least one Flash tube a circle of lamps. The flashing light warning system also has an ignition level that has a Coupling the ignition electrode to the flash tube and with one Clock is connected, the ignition level depending from the clock signals of the clock pulse for the Ignition of the flash tube creates and the energy storage is discharged.

Bei dieser bekannten Sicherheitsabschaltung erweist sich als nachteilig, daß eine Abschaltung des Wandlers nur aufgrund eines Fehlers erfolgt, bei dem die Erzeugung von Spannungsimpulsen in dem Lampenkreis nicht mehr möglich ist. Als besonders nachteilig erweist sich dabei, daß bei einem Körperschluß der Hochspannung gegen Masse, zum Beispiel dann, wenn ein Mensch mit den Zuleitungen zu der Blitzröhre in Berührung kommt, keine Abschaltung des Spannungswandlers erfolgt, da weiterhin Spannungsimpulse in dem Lampenkreis erzeugt werden können.This known safety shutdown proves to be disadvantageous that a shutdown of the converter only due an error occurs in which the generation of Voltage pulses in the lamp circuit are no longer possible. It proves to be particularly disadvantageous that with one Body closure of the high voltage against ground, for example then when a person with the leads to the flash tube comes into contact, no disconnection of the voltage converter occurs because voltage pulses continue in the lamp circuit can be generated.
Der Erfindung liegt die Aufgabe zugrunde, eine Lichtblitzwarnanlage zu schaffen, die bei auftretenden Fehlfunktionen und Beschädigungen eine hohe Sicherheit gegen Zerstörung von Bauteilen der Anlage aufweist und Menschen, die mit hochspannungsführenden Teilen der Anlage in Berührung kommen, bestmöglich vor Schäden schützt.The invention has for its object a Flashing light warning system to be created when occurring Malfunctions and damage a high security against Destruction of components of the system and people, those with high-voltage parts of the system in Come into contact, protects as best as possible from damage.

Ein solcher zu detektierender Fehlerstrom in dem Lampenkreis kann zum Beispiel durch einen Glasbruch an der Blitzröhre oder durch eine Zerstörung der Leitungsisolation im Lampenkreis erfolgen, wenn ein Körperschluß der Hochspannung gegen Masse auftritt. Hierbei wird der Energiespeicher gegen Masse entladen. Wird der Körperschluß durch einen Menschen erzeugt, kann dieser geschädigt werden. In connection with the use in flashing light warning systems proves to be particularly advantageous that the Residual current detection is connected to the clock that the leakage current detection the clock signal from the clock linked to the signal from the current sensor and that a Error signal only outside the pulse duration of the light flashes is generated because it is simple and inexpensive Way through the fault current detection in the lamp circuit flowing current can be detected that is not through the Ignition of the flash tube and the discharge of the Energy storage is due, but outside of Pulse duration of the light flashes, which as current pulses in the Lamp circle can be measured by the current sensor. Such a fault current to be detected in the lamp circuit can be caused, for example, by a broken glass on the flash tube or by destroying the cable insulation in the Lamp circle take place when a body connection of the high voltage against mass occurs. Here, the energy storage is against Unload mass. Will the body close by a human generated, this can be damaged.

Es ist von Vorteil, daß parallel zu der Fehlerstromerkennung in der Verbindung zwischen dem Stromsensor und dem Fehlerspeicher eine Blitzaussetzerkennung angeordnet ist, so daß eine zusätzliche Sicherheit gegeben ist, wenn die Funktionsfähigkeit der Lichtblitzwarnanlage, zum Beispiel bedingt durch einen Abriß der Zuleitung der Blitzröhre oder durch eine mangelnde altersbedingte Zündfähigkeit der Blitzröhre nicht mehr besteht. Auch in diesem Fall erfolgt eine Abschaltung des Spannungswandlers über die Wandlersteuerung und eine Schnellentladung des Energiespeichers über die Schnellentladeschaltung.It is advantageous that parallel to the fault current detection in the connection between the current sensor and the Fault memory a flash misfire detection is arranged, so that there is additional security if the Functionality of the flashing light warning system, for example due to a break in the lead of the flash tube or due to a lack of age-related ignitability of the Flash tube no longer exists.

Um sicherzustellen, daß bei jedem erzeugten Zündimpuls von der Zündstufe (Z) die Blitzröhre (BR) zündet und ein Lichtblitz erzeugt wird, ist parallel zu dem Energiespeicher (E) eine Boosterspannungserzeugung (B) angeordnet, die aus der Spannung von dem Spannungswandler (S) versorgt wird. Diese Boosterspannungserzeugung (B) weist einen hochspannungsfesten Kondensator mit einer kleinen Ladezeitkonstanten zur Einleitung der Blitzentladung auf.To ensure that with each firing pulse generated by the ignition stage (Z) ignites the flash tube (BR) and on Flash of light generated is parallel to the energy storage (E) arranged a booster voltage generation (B) that from the voltage is supplied by the voltage converter (S). This booster voltage generation (B) has one high voltage resistant capacitor with a small Charge time constants to initiate the lightning discharge.
Bei dem hier gezeigten Ausführungsbeispiel ist zwischen der Kathode der Blitzröhre (BR) und dem Energiespeicher (E) ein Stromsensor (SS) angeordnet. Dieser weist beispielhaft eine Diodenanordnung zur Messung des einem Strom in dem Lampenkreis entsprechenden Spannungsabfalls auf. In the embodiment shown here is between the Cathode of the flash tube (BR) and the energy storage (E) Current sensor (SS) arranged. This shows an example Diode arrangement for measuring a current in the Lamp circuit corresponding voltage drop.
Der Stromsensor (SS) ist zum einen mit einer Blitzaussetzerkennung (BA) und zum anderen mit einer Fehlerstromerkennung (FE) elektrisch leitend verbunden. Die Blitzaussetzerkennung (BA) weist beispielhaft eine triggerbare Kippstufe auf, wobei die Triggerung durch die im Lampenkreis durch die Zündung der Blitzröhre (BR) erzeugten Stromimpulse erfolgt. Bei einem zeitlich vorgegebenen Aussetzen der Stromimpulse in dem Lampenkreis erzeugt die Blitzaussetzerkennung (BA) ein Fehlersignal.The current sensor (SS) is on the one hand with a Flash exposure detection (BA) and the other with one Residual current detection (FE) electrically connected. The Lightning misfire detection (BA) shows an example triggerable flip-flop on, the triggering by the im Lamp circle generated by the ignition of the flash tube (BR) Current pulses occur. With a timed Exposing the current pulses in the lamp circuit creates the Flash misfire detection (BA) an error signal.
Die Fehlerstromerfassung (FE) ist zusätzlich mit dem Taktgeber (T) verbunden und weist beispielhaft ebenfalls eine triggerbare Kippstufe auf. Die Fehlerstromerkennung (FE) verknüpft dabei das von dem Stromsensor (SS) gemessene Stromsignal in dem Lampenkreis mit dem von dem Taktgeber (T) erzeugten Taktsignal, das das gleiche ist, das auch die Zündstufe (Z) zur Erzeugung von Zündimpulsen ansteuert, derart, daß ein Fehlersignal nur außerhalb der Impulsdauer der Lichtblitze und der dabei in dem Lampenkreis auftretenden Stromimpulse erzeugt wird. Hierzu kann die Fehlerstromerkennung (FE) zur Verknüpfung der Signale von dem Stromsensor (SS) und dem Taktgeber (T) einen Addierer aufweisen. Die Fehlerstromerkennung (FE) verfügt dabei über ein Zeitglied, mit einer Zeitkonstanten, die größer ist als die Dauer des Blitzimpulses.The residual current detection (FE) is also with the Clock (T) connected and also shows an example a triggerable flip-flop. Residual current detection (FE) links that measured by the current sensor (SS) Current signal in the lamp circuit with that from the clock generator (T) generated clock signal, which is the same as that Triggering ignition stage (Z) to generate ignition pulses, such that an error signal only outside the pulse duration the flashes of light and that in the circle of lamps occurring current pulses is generated. For this, the Residual current detection (FE) for linking the signals from the current sensor (SS) and the clock (T) an adder exhibit. The residual current detection (FE) has a timing element with a time constant that is greater than the duration of the lightning pulse.
Sowohl die Fehlerstromerkennung (FE) als auch die Blitzaussetzerkennung (BA) sind jeweils mit einem Fehlerspeicher (FS) verbunden. Bei vorliegendem Fehlersignal von der Blitzaussetzerkennung (BA) oder der Fehlerstromerkennung (FE) erzeugt der Fehlerspeicher (FS) ein Signal zur Abschaltung des Spannungswandlers (S). Hierzu ist der Fehlerspeicher (FS) elektrisch leitend mit der Wandlersteuerung (W) verbunden. Zudem ist der Fehlerspeicher (FS) elektrisch leitend mit einer Schnellentladeschaltung (SE) verbunden, die bei einem vorliegenden Fehlersignal von der Blitzaussetzerkennung (BA) oder der Fehlerstromerkennung (FE) durch den Fehlerspeicher (FS) aktiviert wird. Die Schnellentladeschaltung (SE) ist elektrisch leitend sowohl mit dem Energiespeicher (E) als auch mit der Boosterspannungserzeugung (B) verbunden und entlädt den Energiespeicher (E) und den Kondensator der Boosterspannungserzeugung (B) bei Ansteuerung durch den Fehlerspeicher (FS) schnellstmöglich. Hierzu weist die Schnellentladeschaltung (SE) einen elektronischen Schalter und einen niederohmigen Entladewiderstand auf.Both the residual current detection (FE) and the Flash exposure detection (BA) are each with a Fault memory (FS) connected. If there is an error signal from the flash exposure detection (BA) or the Fault current detection (FE) is generated by the fault memory (FS) a signal to switch off the voltage converter (S). For this the fault memory (FS) is electrically conductive with the Converter control (W) connected. In addition, the error memory (FS) electrically conductive with a quick discharge circuit (SE) connected, in the event of an error signal of lightning interruption detection (BA) or residual current detection (FE) is activated by the fault memory (FS). The Fast discharge circuit (SE) is both electrically conductive with the energy storage (E) as well as with the Booster voltage generation (B) connected and discharges the Energy storage (E) and the capacitor of the Booster voltage generation (B) when controlled by the Fault memory (FS) as soon as possible. The Fast discharge circuit (SE) an electronic switch and a low-resistance discharge resistor.
Der Taktgeber (T) ist bei dem hier gezeigten Ausführungsbeispiel zur Triggerung elektrisch leitend mit der Wandlersteuerung (W) verbunden.The clock (T) is the one shown here Embodiment for triggering with electrically conductive connected to the converter control (W).
Die Erzeugung eines Fehlersignals durch die Fehlerstromerkennung (FE) erfolgt hier beispielhaft in einer Zeit kleiner gleich 100 Millisekunden und insbesondere etwa 30 Millisekunden nach dem Auftreten eines Fehlerstroms. The generation of an error signal by the Residual current detection (FE) takes place here as an example Time less than or equal to 100 milliseconds and in particular approximately 30 milliseconds after the occurrence of a fault current.
