Description

Die Erfindung betrifft ein Verfahren zur Steuerung des Betriebsablaufs von zwei oder mehr zu einem System gehörenden, räumlich voneinander getrennt angeordneten mobilen Verkehrsampeln oder Warnblinkleuchten, die jeweils einzeln mit Hilfe eines eigenen zeitabhängigen Steuergebers zum Ein- und Ausschalten der Lichtsignale schaltbar sind, sowie eine Verkehrsampel bzw. Warnblinkleuchte zur Durchführung des Verfahrens.The invention relates to a method for controlling the operating sequence of two or more mobile traffic lights or hazard lights which are spatially separated from one another and which can be switched individually with the aid of a separate time-dependent control transmitter for switching the light signals on and off, and a traffic light or Hazard warning lamp to carry out the procedure.

Zum drahtlosen Koordinieren des Betriebsablaufs von transportablen Verkehrsampeln sind Schaltuhren bekannt, die einen Quarztaktgeber als Zeitbasis aufweisen (DE-A-26 32 641). Ampelsysteme mit derartigen Schaltuhren weisen den Nachteil auf, daß die Uhren nach einer bestimmten Zeit infolge von Gangungenauigkeiten voneinander abweichen und dadurch die Koordinierung des Betriebsablaufs der einzelnen Ampeln in dem System nicht mehr gewährleistet ist.For wireless coordination of the operation of transportable traffic lights, time switches are known which have a quartz clock as a time base (DE-A-26 32 641). Traffic light systems with such time switches have the disadvantage that the clocks differ from one another after a certain time as a result of inaccuracies in the movement, and as a result the coordination of the operating sequence of the individual traffic lights in the system is no longer guaranteed.

Ferner ist es bei stationären Straßenverkehrsampelanlagen bekannt, die Systeme mehrerer hintereinanderliegender Knotenpunkte zeitlich genau aufeinander abzustimmen (EP-A-0 021 059). Eine solche genaue Abstimmung kann erforderlich sein, wenn beispielsweise die Ampelsystem auf grüne Welle geschaltet sind. Zur Abstimmung ist in jeder Steuereinrichtung, die einer Knotenpunktanlage zugeordnet ist, ein Empfänger für einen Zeitzeichensender angeordnet. Die empfangenen Zeitzeichensignale werden in der Steuereinrichtung zu einer Korrektur-Steuerinformation verarbeitet, so daß die Schaltabläufe in den einzelnen Steuereinrichtungen genau aufeinander abgestimmt werden können.In the case of stationary traffic light systems, it is also known to coordinate the systems of a plurality of nodes located one behind the other exactly in time (EP-A-0 021 059). Such precise coordination may be necessary if, for example, the traffic light systems are switched to green waves. For tuning purposes, a receiver for a time signal transmitter is arranged in each control device which is assigned to a node system. The received time signal signals are processed in the control device for correction control information, so that the switching sequences in the individual control devices can be precisely coordinated with one another.

Der Erfindung liegt die Aufgabe zugrunde, den Betriebsablauf von zwei oder mehr zu einem System gehörenden, räumlich voneinander getrennt angeordneten mobilen Verkehrsampeln bzw. Warnblinkleuchten zuverlässig und genau zu steuern, so daß auch über längere Zeit eine fehlerfreie Koordinierung der Betriebsabläufe der einzelnen Geräte gewährleistet ist.The invention has for its object to control the operation of two or more belonging to a system, spatially separated mobile traffic lights or hazard lights reliably and accurately, so that error-free coordination of the operations of the individual devices is guaranteed over a long period of time.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß jeder Verkehrsampel oder Warnblinkleuchte die Zeitzeichen eines Zeit- und Normalfrequenzsenders empfangen und unmittelbar zur Steuerung des jeweiligen Steuergebers verwendet werden und daß in einer der Ampeln des Systems (Mutterampel) oder Warnblinkleuchten die Anzahl der empfangenen Zeitzeichen für die Rot-, Gelb- und Grün- bzw. Blinkperioden für jede Ampel oder Warnblinkleuchte des Systems eingegeben und gespeichert wird, die gespeicherten Rot-, Gelb-und Grünperioden bzw. Blinkperioden für jede andere Ampel (Tochterampel) oder Warnblinkleuchte zu dieser transportiert und von dieser eingelesen wird.According to the invention, this object is achieved in that each traffic light or hazard warning light receives the time signals from a time and normal frequency transmitter and is used directly to control the respective control transmitter and that in one of the traffic lights of the system (mother light) or hazard warning lights the number of received time signals for the red -, yellow and green or flashing periods are entered and saved for each traffic light or hazard warning light of the system, the stored red, yellow and green periods or flashing periods for each other traffic light (daughter traffic light) or hazard warning flashing light are transported to and read from it becomes.

Dieses System läßt sich sehr gut bei transportablen Verkehrsampeln oder Warnblinkleuchten, die zur Sicherung von Baustellen vorgesehen sind, anwenden, wobei diese aus mindestens einer an einem Ständer befestigbaren, mit einer oder mehreren Signallampen ausgestatteten Leuchteinheit, einem mit dem unteren Ständerende verbundenen Batteriekasten, in dem eine oder mehrere zum Betrieb der Signallampen dienende Batterien angeordnet sind, oder einem Netzanschluß sowie einem einstellbaren Steuergeber zum zeitabhängigen wahlweisen Ein-und Ausschalten der einzelnen Signallampen bzw. der Signallampe bestehen.This system can be used very well with portable traffic lights or hazard warning lights intended to secure construction sites, these consisting of at least one light unit that can be attached to a stand, equipped with one or more signal lamps, a battery box connected to the lower end of the stand, in which one or more batteries for operating the signal lamps are arranged, or there is a mains connection and an adjustable control transmitter for time-dependent optional switching on and off of the individual signal lamps or the signal lamp.

Um bei einer solchen mobilen Verkehrsampel oder Warnblinkleuchte das erfindungsgemäße Verfahren durchführen zu können, ist in oder an der Ampel oder der Warnblinkleuchte ein Funkempfänger zum Empfang des von einem Zeit- und Normalfrequenzsender gesendeten Zeitzeichens angeordnet, wobei der Empfänger mit dem Steuergeber verbunden ist, an der Ampel oder der Warnblinkleuchte ein Tastenfeld zum Einprogrammieren der Ein- und Ausschaltzeiten in den Steuergeber vorgesehen ist und ein Schaltkasten mit einem Stecker für mindestens einen weiteren, für eine andere, synchron zu steuernde Ampel oder Warnblinkleuchte vorgesehenen transportierbaren Steuergeber angeordnet ist.In order to be able to carry out the method according to the invention in such a mobile traffic light or hazard warning light, a radio receiver for receiving the time signal sent by a time and normal frequency transmitter is arranged in or at the traffic light or the hazard warning light, the receiver being connected to the control transmitter at which At traffic lights or the hazard warning lights, a keypad is provided for programming the switch-on and turn-off times in the control transmitter, and a switch box with a plug is arranged for at least one further transportable control transmitter provided for another traffic light or hazard warning lights to be controlled synchronously.

Bei den erfindungsgemäßen Ampeln bzw. Warnblinkleuchten genügt ein einmaliges Einstellen der Schaltphasen, deren genaue zeitliche Folge dann über einen unbegrenzten Zeitraum unverändert aufrechterhalten werden kann. Aufgrund der Gleichlaufgenauigkeit ist es möglich, die erfindungsgemäße Ampel bzw. Warnblinkleuchte mit beliebig vielen anderen Ampeln bzw. Warnblinkleuchten zu kombinieren, wobei gewährleistet ist, daß die in jeder Ampel bzw. Warnblinkleuchte eingestellten Phasen zeitlich genau aufeinander abgestimmt bleiben. Ein solches System arbeitet sehr zuverlässig und ist darüber hinaus im Betrieb äußerst einfach zu handhaben und nicht störungsanfällig, da die Zeitzeichensignale unmittelbar zur Schaltung ausgewertet werden können.In the case of the traffic lights or hazard warning lights according to the invention, it is sufficient to set the switching phases once, the exact chronological sequence of which can then be maintained unchanged over an unlimited period of time. Because of the synchronization accuracy, it is possible to combine the traffic light or hazard warning light according to the invention with any number of other traffic lights or hazard warning lights, ensuring that the phases set in each traffic light or hazard warning light remain precisely coordinated with one another in terms of time. Such a system works very reliably and, moreover, is extremely easy to use during operation and is not susceptible to faults, since the time signal signals can be evaluated directly for switching.

Um evtl. kurzfristige Sende- oder Empfangsstörungen des Zeitzeichens zu überbrücken, kann in der Ampel oder Warnblinkleuchte zusätzlich ein Quarztimer als Gangreserve vorgesehen sein. Sobald das Zeitzeichen nach der Störung wieder empfangen werden kann, wird die Zeit sofort nachkorrigiert, ohne daß es einer Neueinstellung des zeitlichen Ablaufs des Programms bedarf.In order to bridge any short-term transmission or reception disturbances of the time signal, a quartz timer can also be provided as a power reserve in the traffic light or hazard warning lamp. As soon as the time signal can be received again after the disturbance, the time is corrected immediately without the need to reset the program's timing.

Der zum Empfang der Zeitzeichen erforderliche Ferritstab, der jeder Verkehrsampel bzw. Warnblinkleuchte zugeordnet ist, ist vorzugsweise in ein Kunststoffrohr eingeschäumt, so daß er nach außen hin geschützt ist.The ferrite rod required to receive the time signals, which is assigned to each traffic light or hazard warning lamp, is preferably foamed into a plastic tube so that it is protected from the outside.

Die Erfindung ist in der Zeichnung beispielsweise veranschaulicht und im nachstehenden im einzelnen anhand der Zeichnung beschrieben. Es zeigen:

  • Fig. 1 eine Ansicht einer Warnblinkleuchte, teilweise im Schnitt,
  • Fig. 2 eine Draufsicht auf die Warnblinkleuchte gemäß Fig. 1, wobei die Antenne in zwei Stellungen dargestellt ist, und
  • Fig. 3 eine transportable Verkehrsampel.
The invention is illustrated in the drawing, for example, and in described in detail below with reference to the drawing. Show it:
  • 1 is a view of a hazard warning lamp, partly in section,
  • Fig. 2 is a plan view of the hazard warning lamp of FIG. 1, the antenna being shown in two positions, and
  • Fig. 3 is a portable traffic light.

Nach Fig. 1 und 2 der Zeichnung umfaßt die Warnblinkleuchte 1 im wesentlichen einen Ständer 2 und eine Leuchteinheit 3. Der Ständer 2 ist bei dem in der Zeichnung dargestellten Ausführungsbeispiel als hohler Kunststoffkasten ausgebildet, in dem zwei Batterien 4 und 5 sowie ein Empfänger 6 und ein Steuergeber 7 untergebracht sind.1 and 2 of the drawing, the hazard warning lamp 1 essentially comprises a stand 2 and a lighting unit 3. The stand 2 is formed in the embodiment shown in the drawing as a hollow plastic box in which two batteries 4 and 5 and a receiver 6 and a control transmitter 7 are housed.

Der Ständer 2 kann entweder unmittelbar zum aufstellen der Warnblinkleuchte 1 dienen, jedoch ist es auch möglich, den im vorliegenden Fall relativ klein ausgebildeten Ständer 2 oben auf einer in der Zeichnung nicht dargestellten Bake zu befestigen.The stand 2 can either be used directly to set up the hazard warning lamp 1, but it is also possible to fasten the stand 2, which in the present case is relatively small, on top of a beacon, not shown in the drawing.

Die Leuchteinheit 3 besteht in bekannter Weise aus einem Gehäuse 8 aus gelblich durchscheinendem Kunststoffmaterial mit einem umlaufend angeordneten Reflektor 9. Im Innern des Gehäuses 8 ist eine Signallampe 10 angeordnet, die über die beiden Batterien 4 und 5 und den Steuergeber 7 gespeist wird.The lighting unit 3 consists in a known manner of a housing 8 made of yellowish translucent plastic material with a circumferentially arranged reflector 9. Inside the housing 8, a signal lamp 10 is arranged, which is fed by the two batteries 4 and 5 and the control transmitter 7.

Oben auf der Leuchteinheit 3 sitzt eine Empfangsantenne 11, die über eine Verbindungsleitung 12 mit dem Empfänger 6 verbunden ist. Alternativ könnte die Antenne auch in dem Batteriekasten angeordnet sein. Die in der Zeichnung dargestellte Antenne 11 ist als an sich bekannte Ferritstabantenne ausgebildet, bei der der Ferritstab 13 von einer Spule 14 umgeben ist deren Enden mit einer Platine 15 sowie über diese mit der zu dem Empfänger 6 führenden Leitung 12 verbunden sind.On top of the lighting unit 3 there is a receiving antenna 11 which is connected to the receiver 6 via a connecting line 12. Alternatively, the antenna could also be arranged in the battery box. The antenna 11 shown in the drawing is designed as a ferrite rod antenna known per se, in which the ferrite rod 13 is surrounded by a coil 14, the ends of which are connected to a circuit board 15 and via this to the line 12 leading to the receiver 6.

Dar Ferritstab 13 einschließlich Spule 14 und Platine 13 sind in einem Kunststoffrohr 16 untergebracht, dessen beide Enden durch aufgesetzte Deckel 17 verschlossen sind und wobei der Innenraum mit einem Kunststoffschaum 18 ausgefüllt ist.The ferrite rod 13 including coil 14 and circuit board 13 are accommodated in a plastic tube 16, the two ends of which are closed by attached covers 17 and the interior is filled with a plastic foam 18.

Um die Antenne 11 optimal ausrichten zu können, ist diese um eine vertikale Achse drehbar auf der Leuchteinheit 3 angeordnet. Ale Drehachse weist das Kunststoffrohr 16 eine mittig angesetzte Hülse 19 auf, die genau rechtwinklig zu der Achse des Rohrs 16 liegt. Die Hülse 19 ist mit Spiel auf einen oben auf der Leuchteinheit 3 angeordneten Hohlzapfen 20 aufgesteckt. Zur Begrenzung des Drehwinkels der Antenne 11 auf etwa 90° ist in der Außenseite des Hohlzapfene 20 eine Nut 21 vorgesehen, die sich über ein Kreisbogen von etwas mehr als 90° erstreckt. In diese Nut 21 greift eine Schraube 22 ein, die von außen durch die Wandung des Hohlzapfens 19 hindurchgeschraubt ist.In order to be able to optimally align the antenna 11, it is arranged on the lighting unit 3 so as to be rotatable about a vertical axis. At the axis of rotation, the plastic tube 16 has a sleeve 19 which is attached in the center and which is exactly at right angles to the axis of the tube 16. The sleeve 19 is fitted with play onto a hollow pin 20 arranged at the top of the lighting unit 3. In order to limit the angle of rotation of the antenna 11 to approximately 90 °, a groove 21 is provided in the outside of the hollow pin 20, which extends over a circular arc of somewhat more than 90 °. A screw 22 engages in this groove 21 and is screwed from the outside through the wall of the hollow pin 19.

Die Verbindungsleitung 12 zwischen dem Ferritstab 13 und dem Empfänger 6 ist durch den Innenraum des Hohlzapfens hindurchgeführt und verläuft durch das Innere der Leuchteinheit bis hinunter zu dem Empfänger 6, so daß die Leitung nach außen nicht in Erscheinung tritt.The connecting line 12 between the ferrite rod 13 and the receiver 6 is passed through the interior of the hollow pin and runs through the interior of the lighting unit down to the receiver 6, so that the line does not appear to the outside.

Wie in Fig. 2 dargestellt ist, kann die Antenne aus der mit ausgezogenen Linien dargestellten Lage, in der sie parallel zu der Breitseite der Leuchteinheit liegt, in eine um 90° versetzte, strichpunktiert dargestellte Querlege geschwenkt werden. Aufgrund der Begrenzung des Schwenkwinkels besteht keine Gefahr, daß sich die Verbindungsleitung 12 verdrillt.As shown in FIG. 2, the antenna can be pivoted out of the position shown in solid lines, in which it lies parallel to the broad side of the lighting unit, into a transverse laying, shown in dash-dot lines, by 90 °. Due to the limitation of the swivel angle, there is no danger that the connecting line 12 will twist.

Für den Fall, daß bei einem Defekt des DCF 77-Senders bzw. des Empfängers 6 die Anlage ausfällt, ist eine Sicherheitsschaltung vorgesehen, die im Störfall auf Dauerlicht umschaltet.In the event that the system fails in the event of a defect in the DCF 77 transmitter or the receiver 6, a safety circuit is provided which switches to continuous light in the event of a fault.

Bei der in Fig. 3 dargestellten transportablen Verkehrsampel 31 handelt es sich um ein Ausführungsbeispiel, wie es zur Sicherung von Baustellen verwendet wird. Eine solche Verkehrsampel arbeitet normalerweise mit mindestens einer weiteren Ampel zusammen, wobei die beiden Ampeln an beiden Enden einer Baustelle stehen und einen umschaltbaren Einbahnverkehr steuern.The transportable traffic light 31 shown in FIG. 3 is an embodiment of the type used for securing construction sites. Such a traffic light normally works together with at least one other traffic light, the two traffic lights standing at both ends of a construction site and controlling switchable one-way traffic.

Die Ampel 31 besteht aus einem rohrförmigen Ständer 32, einer am oberen Ständerende angeordneten, mit drei Signallampen ausgestatteten Leuchteinheit 33 sowie einem mit dem unteren Ständerende verbundenen Batteriekasten 34. Zur Fortbewegung der Ampel sind unter dem Batteriekasten Räder 35 angeordnet.The traffic light 31 consists of a tubular stand 32, a lighting unit 33 arranged at the upper end of the stand and equipped with three signal lamps, and a battery box 34 connected to the lower end of the stand. Wheels 35 are arranged under the battery box for moving the traffic light.

Die Leuchteinheit 33 besteht aus drei übereinander angeordneten Reflektorgehäusen 36, 37 und 38 mit den drei Farben Grün, Gelb und Rot. Die Signallampen werden von einer in dem unten angeordneten Kasten 34 untergebrachten Batterie gespeist. Alternativ ist es jedoch auch möglich, einen Netzanschluß vorzusehen.The lighting unit 33 consists of three superimposed reflector housings 36, 37 and 38 with the three colors green, yellow and red. The signal lamps are fed by a battery housed in the box 34 arranged below. Alternatively, however, it is also possible to provide a network connection.

Oben auf der Ampel 33 ist eine Antenne 39 vorgesehen, die mit einem in einem Schaltkasten 40 angeordneten Empfänger 41 verbunden ist. Der Empfänger 41 dient zum Empfang des von dem Zeit- und Normalfrequenzsender DCF 77 gesendeten Zeitzeichens, das in Abständen von jeweils 1 Sekunde gesendet wird. Die Zeitangabe wird kodiert auf der Trägerfrequenz gesendet. Über einen Verstärker 42 werden die Signale an einen Geber 43 (Kontrollsteuerung) weitergegeben, der über ein außen an dem Schaltkasten angeordnetes Tastenfeld 44 programmierbar ist.An antenna 39 is provided at the top of the traffic light 33 and is connected to a receiver 41 arranged in a switch box 40. The receiver 41 serves to receive the time signal transmitted by the time and normal frequency transmitter DCF 77, which is transmitted at intervals of 1 second. The time is transmitted in coded form on the carrier frequency. The signals are forwarded via an amplifier 42 to a transmitter 43 (control control) which can be programmed via a keypad 44 arranged on the outside of the switch box.

Außen an dem Schaltkasten 40 sind ferner noch Schalter 45 für eine eventuelle Handsteuerung vorgesehen sowie ein Stecker 46 zum Einstecken eines weiteren Steuergebers, der synchron mit dem eingebauten Geber 43 mit Hilfe des Tastenfeldes 44 programmierbar ist.On the outside of the switch box 40 there are also switches 45 for a possible manual control and a plug 46 for inserting a further control transmitter, which can be programmed synchronously with the built-in transmitter 43 using the keypad 44.

Der nach der Programmierung von dem Stecker 46 abgezogene Geber kann dann auf einen entsprechenden Stecker einer zweiten Ampel aufgesteckt werden, die dann mit der ersten Ampel synchron arbeitet.The encoder withdrawn from the connector 46 after programming can then be plugged into a corresponding connector at a second traffic light, which then operates synchronously with the first traffic light.

Um Fehler beim Programmieren und im Betrieb zu vermeiden, ist die erste Ampel nur dann programmierbar, wenn in diese die für die weiteren Ampeln vorgesehenen Geber eingesteckt sind. Andererseits können die abhängigen Ampeln erst anlaufen, wenn die in der ereten Ampel vorprogrammierten transportablen Geber eingesteckt sind.In order to avoid errors during programming and operation, the first traffic light is only then Programmable if the sensors provided for the other traffic lights are plugged into them. On the other hand, the dependent traffic lights can only start up when the portable transmitters pre-programmed in the first traffic light are plugged in.

Um zu gewährleisten, daß die Ampelanlage auch bei einem Defekt des CDF 77-Senders bzw. des Empfängers 41 störungsfrei weiterarbeitet, ist ein Quarztimer 47 ale Gangreserve eingebaut. Er besteht aus einem temperaturstabilisierten Quarzschwingkreis.A quartz timer 47 ale power reserve is installed to ensure that the traffic light system continues to function properly even if the CDF 77 transmitter or receiver 41 is defective. It consists of a temperature-stabilized quartz resonant circuit.
