Abstract

The signalling system uses signal lights evenly spaced in a continuous sequence along the edges of the road and coupled in groups, each having a respective photocell control. This is adjustable to respond to a given restricted visibility level being reached to switch the signal lights into operation. The lights are subsequently switched out of use when the photocell control detects improved visibility. Pref. the signal lights are associated with standard means for designating the road edges, e.g. kerbstones or guide barriers.

Description

Die Erfindung betrifft ein Zichtsignalisierungs-System in kontinuierlicher Folge den Strassenrändern entlang zur Fahrterleichterung für die Fahrzeuge bei durch Nebel erschwerter Sicht.The invention relates to a direction signaling system in a continuous sequence along the road edges to make driving easier for the vehicles when visibility is difficult due to fog.

Die durch Nebel erschwerten Sichtverhältnisse bilden bekanntlich eine gefährliche Behinderung eines fliessen den und sicheren Strassenverkehr für die Kraftfahrzeuge bzw. die Fahrzeugbenutzer. Während bei klarer Sicht der Strassenrand selbst wie auch am Strassenrand fest angeordnete Hinweis- oder Schutzvorrichtungen, wie Leit planken, Geländer, Prellsteine u.dgl. für die Fahrer ei ne Fahr- bzw. lenkhilfe darstellen, sind diese Mittel bei Nebel schwer oder gar nicht sichtbar und reichen daher nicht aus, den Strassenverlauf wirksam anzuzeigen.As is well known, the visibility conditions, which are hampered by fog, form a dangerous impediment to flowing and safe road traffic for the motor vehicles and vehicle users. While with a clear view of the road itself as well as on the roadside fixed information or protective devices such as guardrails, railings, bumpers and the like. represent a driving or steering aid for the driver, these means are difficult or not visible in fog and are therefore not sufficient to effectively display the course of the road.

Schwere und häufige Unfäller sind leider die Folge einer bei Nebel unzureichenden Sicht des Strassenrandes und anderer Hinweis- oder Schutzmittel, die den Strassenverlauf anzeigen sollen.Serious and frequent accidents are unfortunately the result of insufficient visibility of the roadside in fog and other information or protection devices that should show the course of the road.

Es ist auch zu beachten, dass sich der Nebel nicht immer gleichmässig dicht und zusammenhängend bildet;viel mehr bilden sich oft in Abhängigkeit von den Witterungs bedingungen stellen- und zeitweise Nebelbänke und Nebel wände, die sich rasch und plötzlich in Bezig auf Dichte und 0rtlichkeit verändern können. Das stellt eine weite re Ermüdungs- und Gefahrenursache für die Fahrer dar infolge der sich fortzu verändernden Sichtbarkeit des Strassenrandes und anderer Mittel, die den Strassenverlauf anzeigen sollen.It should also be noted that the fog is not always uniformly dense and coherent; rather, depending on the weather conditions, fog banks and fog walls form occasionally and temporarily, which quickly and suddenly change in density and location can. This represents a further cause of fatigue and danger for the drivers due to the continuously changing visibility of the roadside and other means which are intended to indicate the course of the road.

Es ist Aufgabe der Erfindung, diese beim Fahren im Nebel auftretenden Schwierigkeiten zu beseitigen oder zum wenigsten in möglichst hohem Masse zu verringern.It is an object of the invention to eliminate these difficulties that occur when driving in fog or at least to reduce them as much as possible.

Gelöst ist diese Aufgabe erfindungsgemäss durch ein Lichtsignalisierungs-System in kontinuierlicher Folge den Strassenrändern entlang zur Fahrterleichterung bei durch Nebel erschwerter Sicht, dessen Wesensmerkmal (An spruch 1) darin besteht, dass einer Verkehrsstrasse ent lang Photozellen-Steuerungen angeordnet sind, die auf durch den Nebel verursachte, den Strassenverkehr beeinflussende Sichtveränderungen ansprechen, mit entsprechenden elektrischen Stromversorgungsstellen innerhalb von Gruppen von elektrischen Lichtsignalvorrichtungen, die den Strassenrändern entlang mit gegenseitigem Abstand, in kontinuierlicher Folge und als feststehende die Fahrbahn begrenzende Hinweismittel angeordnet sind, wobei die Empfindlichkeit der Photozellen-Steuerungen auf einen vorbestimmbaren Wert des Verdunkelungsvermögens des Nebels einstellbar ist, um die wahlweise Um- " schaltung auf Schliessen oder Offnen der elektrischen Stromkreisleitungen zur Verbindung der Gruppen von Licht signalvorrichtungen derart zu bewirken, dass sobald sich im Bereich der Photozellen-Steuerungen Nebel mit einem gegenüber dem vorbestimmten Wert gleichen oder grösseren Verdunkelungsvermögen bildet, die Photozellen-Steuerung die elektrische Verbindung der entsprechenden Kreisleitungen und daher die Stromversorgung für die zugehörige Gruppe elektrischen Lichtsignalvorrichtungen auslöst und so deren Aktivierung verursacht, damit sie als Lichthinweismittel den verlauf der Fahrbahn anzeigen, während bei Wiederherstellung normaler Sichtverhältnisse die Lichtsignalvorrichtungen infolge der durch die Photozellen-Steuerung verursachte Umschaltung auf Öffnung der zu gehörigen elektrischen Kreisleitung stromlos werden.This object is achieved according to the invention by a light signaling system in a continuous sequence along the roadside to make driving easier when visibility is difficult due to fog, the essential feature of which (claim 1) is that a traffic road along photocell controls are arranged which are directed through the fog caused changes in visibility influencing road traffic, with corresponding electrical power supply points within groups of electrical light signal devices, which are arranged along the roadside at a mutual distance, in a continuous sequence and as fixed means of delimitation of the roadway, the sensitivity of the photocell controls to a predeterminable level The value of the darkening ability of the mist can be adjusted in order to "switch over to closing or opening the electrical" To effect circuit lines for connecting the groups of light signaling devices in such a way that as soon as fog forms in the area of the photocell controls with a darkening capacity equal to or greater than the predetermined value, the photocell control unit provides the electrical connection of the corresponding circular lines and therefore the power supply for the associated group triggers electrical light signal devices and thus causes their activation so that they indicate the course of the road as light indicating means, while when normal visibility is restored, the light signal devices become de-energized as a result of the switchover to opening of the associated electrical circuit line caused by the photocell control.

Gemäss einer abgeänderten Ausführungsform können die elektrischen Lichtsignalvorrichtungen direkt geeigneten feststehenden Hinweismitteln zur Anzeige des Fahrbahnver laufs zugeordnet werden (Anspruch 2).According to a modified embodiment, the electrical light signal devices can be assigned directly to suitable, fixed information means for displaying the course of the carriageway (claim 2).

Nachfolgend wird die Erfindung anhand eines in der Zeich nung dargestellten Ausführungsbeispiels näher beschrieben.The invention is described in more detail using an exemplary embodiment shown in the drawing.

Die einzige Figur der Zeichnung zeigt schematisch und in vereinfachter Form eine Draufsicht des erfindungsgemlssen Lichtsignalisierungs-Systems in kontinuierlicher Fol ge den Strassenrändern entlang zur Fahrterleichterung für die Fahrzeuge bei durch Nebel erschwerten Sichtverhältnissen.The single figure of the drawing shows schematically and in simplified form a top view of the light signaling system according to the invention in a continuous sequence along the road edges to make driving easier for the vehicles when visibility is difficult due to fog.

Im Einzelnen zeigt die Figur eine insgesamt mit 10 bezeichnete Verkehrstrasse, von der beispielsweise drei aufeinander folgende Abschnitte 10a, 10b, 10c dargestellt sind.In detail, the figure shows a traffic route, designated overall by 10, of which, for example, three successive sections 10a, 10b, 10c are shown are.

Mit 11 ist die Fahrbahn al solche (im dargestellten Bei spiel zweispurig) bezeichnet, während mit 12 die seitli chen, die Fahrbahn 11 der Strasse 10 begrenzenden Randstreifen bezeichnet sind.With 11, the roadway al such (in the illustrated example, two-lane game) is designated, while with 12 the side, the roadway 11 of the road 10 border strips are designated.

Erfindungsgemäss sind entlang jedem der beiden Strassen ränder, die durch die Aussenseite der Randstreifen 12 der Strasse 10 begrenzt sind, mehrere elektrische Licht signalvorrichtungen in schematischer Andeutung bei 13.1, 13.2 aneinander gereiht, die z.B. als herkömmliche Beleuchtungslampen mit entsprechenden Tragstützen und gegebenenfalls mit Leitvorrichtungen für die Lichtstrahlen der Lampen, um ihre richtungsweisende Sichtbarkeit den Fahrern gegenüber sicherzustellen, ausgebildet sind.According to the invention, along each of the two streets, which are delimited by the outside of the edge strips 12 of the street 10, a plurality of electrical light signal devices are arranged in a schematic manner at 13.1, 13.2, which e.g. are designed as conventional lighting lamps with corresponding support brackets and optionally with guide devices for the light rays of the lamps in order to ensure their directional visibility to the drivers.

Die genannten elektrischen Lichtsignalvorrichtungen 13.1, 13.2 sind mit gleichmässigem Abstand untereinander einer geeigneten Teilung entsprechend in kontinuierlicher Folge jedem Strassenrand entlang angeordnet und zwar in einer Lage und mit der Funktion von feststehenden, die Fahrbahn 11 begrenzenden Hinweismitteln, um bei durch Ne bel erschwerter Sicht durch ihre Lichtsignalisierung den Verlauf der Fahrbahn 11 anzuzeigen.The aforementioned electrical light signal devices 13.1, 13.2 are arranged at a uniform distance from one another, in a suitable division, in a continuous sequence along each road edge, in one position and with the function of fixed information means delimiting the roadway 11 in order to provide a view that is more difficult due to fog Light signaling to display the course of the road 11.

Gemäss einer abgeänderten Ausführungsform sind die elektrischen Signalvorrichtungen feststehenden Hinweismitteln herkömmlicher Art, wie Prellsteinen, Leitplanken oder anderen Strassenbegrenzungsmitteln, zugeordnet.According to a modified embodiment, the electrical signaling devices are assigned to fixed information means of a conventional type, such as bumpers, crash barriers or other road limitation means.

Die elektrischen Lichtsignalvorrichtungen 13.1, 13.2 sind in bekannter Weise über entsprechende Kreisleitungen 14.1, 14.2, die in der Zeichnung strichpunktiert angedeutet sind, mit zugeordneten Stromversorgungsstellen 15.1, 15.2 verbunden und bilden dadurch im dargestellten Beispiel zwei feststehende Gruppen 1, 2 von Lichtsignalvorrichtungen. Diese Gruppen sind elektrisch voneinander unabhängig und ihre Lichtsignalvorrichtungen folgen aufeinander auf bestimmt abgelängten Strecken der Fahrbahn 11.The electrical light signal devices 13.1, 13.2 are in a known manner via corresponding circular lines 14.1, 14.2, which are dash-dotted in the drawing are indicated, connected to assigned power supply points 15.1, 15.2 and thereby form two fixed groups 1, 2 of light signal devices in the example shown. These groups are electrically independent of one another and their light signal devices follow one another on certain lengths of the roadway 11.

Dementsprechend folgen auf einer Seite die Lichtsignalvorrichtungen 13.1 der Gruppe 1 aufeinander auf der Strecke der Strasse 10, die den Abschnitt 10a und etwa die Hälfte des Abschnittes 10b umfasst.Accordingly, on one side the light signal devices 13.1 of group 1 follow one another on the route of road 10, which comprises section 10a and approximately half of section 10b.

An der anderen Seite hingegen folgen die Lichtsignalvor richtungen 13.2 der Gruppe 2 aufeinander auf der Strecke der Strasse 10, die die andere Hälfte des Abschnittes 10b und den Abschnitt 10c umfasst.On the other hand, however, the light signal devices 13.2 of group 2 follow one another on the route of road 10, which comprises the other half of section 10b and section 10c.

Erfindungsgemäss sind entlang der Verkehrstrasse 10 Photozellen-Steuerungen 16.1, 16.2 angeordnet, die auf die durch den Nebel verursachten schlechten Sichtverhältnissen für den Strassenverkehr ansprechen und mit den Strom versorgungsstellen 15.1, 15.2 über die Kreisleitungen 14.1, 14.2 der Gruppen 1, 2 von Lichtsignalvorrichtungen 13.1, 13.2 verbunden sind. Die Photozellen-Steuerungen 16.1, 16.2 dienen dementsprechend dazu, die der Strasse 10 entlang infolge des Nebels auftretenden Änderungen der Sichtverhältnisse, wie etwa die Änderungen der Inten sität des einfallenden Lichtflusses (Pfeile F1, F2), zu erfassen, dem zufolge die wahlweise Umschaltung der zuge ordneten Kreisleitungen 14.1, 14.2 auf Schliessen oder " Offnen zu bewirken und so die Gruppen 1, 2 der Lichtsignalvorrichtungen 13.1, 13.2 mit Strom zu versorgen bzw.According to the invention 10 photocell controls 16.1, 16.2 are arranged along the traffic road, which respond to the poor visibility conditions caused by the fog for road traffic and with the power supply points 15.1, 15.2 via the circular lines 14.1, 14.2 of groups 1, 2 of light signal devices 13.1, 13.2 are connected. Accordingly, the photocell controls 16.1, 16.2 serve to detect the changes in visibility that occur along the street 10 as a result of the fog, such as the changes in the intensity of the incident light flux (arrows F1, F2), accordingly the optional switching of the assigned circuit lines 14.1, 14.2 to close or "open" and thus to supply groups 1, 2 of the light signal devices 13.1, 13.2 with current or

stromlos zu machen. Diese an sich bekannten Photozellen-Steuerungen 16.1, 16.2 sind in ihrer Empfindlichkeit auf einen vorbestimmbaren Wert des Verdunkelungsvermögens des Nebels derart eingestellt, dass sobald sich in ihrem Bereich Nebel mit einem gegenüber dem eingestellten Wert gleichen oder grösseren Verdiznkelungsvermögen bildet, die Photozellen-Steuerungen 16.1, 16.2 die elektrische Verbindung der zugeordneten Kreisleitungen 14.1, 14.2 herstellen. Dadurch werden die Gruppen 1, 2 von Lichtsig nalvorrichtungen 13.1, 13.2 mit Strom versorgt, leuchten auf und zeigen den Verlauf der Fahrbahn an.to de-energize. This known photocells controllers 16.1, 16.2 of the V are in their sensitivity to a predeterminable value erdunkelungsvermögens set of the mist so that the photocell controls once in their area mist with an equal relative to the set value or is larger Verdiznkelungsvermögen 16.1 , 16.2 establish the electrical connection of the associated circular lines 14.1, 14.2. As a result, groups 1, 2 are supplied with power by light signal devices 13.1, 13.2, light up and indicate the course of the roadway.

Dieser Zustand wird durch die Photozellen-Steuerungen 16.1, 16.2 aufrechterhalten, solange in ihrem Bereich die durch den Nebel erschwerte Sicht andauert. Sobald sich der Strasse 10 entlang im betreffenden Bereich der Photo zellen-Steuerungen wieder normale Sichtverhältnisse einstellen, d.h. der Nebel in diesem Bereich aufhöhrt, dann schalten die Photozellen-Steuerungen 16.1, 16.2 die entsprechende Kreisleitung 14.1, 14.2 der Signalvorrichtungen 13.1, 13.2 auf den Offnungszustand um, wodurch die von Versorgungsstellen 15.1, 15.2 ausgehende Stromversor gung der Lichtsignalvorrichtungen 13.1, 13.2 der Gruppen 1, 2 unterbrochen wird. Dieser Zustand wird wiederum aufrecht erhalten, solange im Bereich der Photozellen 16.1, 16.2 kein Nebel mit gegenüber dem eingestellten Wert gleichem oder grösserem Verdunkelungsvermögen auftritt, d.h. solange auf der betreffenden Strassenstrecke eine für den Verkehr hinreichende Sicht ohne Zuhilfenahme der feststehenden Lichthinweismittel herrscht.This state is maintained by the photocell controls 16.1, 16.2 as long as the view obstructed by the fog persists in its area. As soon as street 10 is back in the relevant area of the photo cell controls, normal visibility, i.e. the fog stops in this area, then the photocell controls 16.1, 16.2 switch the corresponding circuit 14.1, 14.2 of the signal devices 13.1, 13.2 to the open state, as a result of which the power supply from the supply points 15.1, 15.2 supplies the light signal devices 13.1, 13.2 of groups 1 , 2 is interrupted. This state is again maintained as long as there is no fog in the area of the photocells 16.1, 16.2 with the same or greater darkening capacity than the set value, i.e. as long as there is sufficient visibility for the traffic on the relevant road section without the aid of the fixed light warning devices.

Wie aus dem Vorausgehenden eindeutig hervorgeht, ist die Aktivierung der Lichtsignalvorrichtungen 13.1, 13.2, wel ehe die festen Lichthinweisgruppen 1, 2 bilden, ganz un- abhängig von Bedienungspersonen und wird bei einer Nebel bildung mit einem gegenüber dem eingestellten Wert der Photozellen 16.1, 16.2 etwa gleichen Verdunkelungsvermögen automatisch bewirkt. Ebenso werden die Lichtsignalvorrichtungen 13.1, 13.2 automatisch stromlos, so - bald sich der Nebel auflöst.As is clear from the foregoing it is the activation of the light signal devices 13.1, 13.2, wel before the solid light Note groups 1, 2 form, all un - depending on operators and is at a fog formation with an approximately equal darkening capacity compared to the set value of the photocells 16.1, 16.2. Likewise, the light signal devices 13.1, 13.2 are automatically de-energized as soon as the fog dissolves.

Nachdem die Stromversorgung der einzelnen Gruppen 1, 2 von Lichtsignalvorrichtungen 13.1, 13.2 jeweils unabhän gig voneinander durch die Photozellen 16.1, 16.2 gesteuert wird, werden bei der Bildung von Nebelbänken oder stellen- bzw. zeitweisen Nebelwänden nur jene Grup pen von Lichtsignalvorrichtungen aktiviert, die sich auf den betreffenden nebeligen Strecken der Fahrbahn 11 befinden. Dadurch erreicht man eine erhebliche Rationalisierung des Stromverbrauchs einerseits und eine grössere Gleichmässigkeit der Sichtverhältnisse hinsichtlich der aufeinander folgenden, feststehenden Hinweismittel trotz der durch die Nebelbänke stark veränderlichen Sichtverhältnisse.After the power supply of the individual groups 1, 2 of light signal devices 13.1, 13.2 is controlled independently of one another by the photocells 16.1, 16.2, only those groups of light signal devices that are activated are activated when fog banks or partially or temporarily fog walls are formed are on the relevant foggy stretches of roadway 11. This results in a considerable rationalization of the power consumption on the one hand and a greater uniformity of the viewing conditions with regard to the successive, fixed information means, despite the visibility conditions which can be greatly changed by the fog banks.

Somit zeigt das erfindungsgemässe Lichtsignalisierungs-System in kontinuierlicher Folge den Strassenrändern ent lang bei Nebel den Verlauf der Fahrbahn wirksam an für die eventuell unter Einschaltung der tiefer angeordneten Scheinwerfer verkehrenden Fahrzeuge. Den Fahrern selbst wird dadurch die Lenkung des Fahrzeugs bei Nebel vorteil haft erleichtert, wodurch die Fahrt zwar bei verringerter Geschwindigkeit, jedoch mit grösserer Sicherheit und geringerer Ermüdung erfolgen kann.Thus, the light signaling system according to the invention continuously shows the course of the road along the roadside along the fog effectively for the vehicles that may be traveling with the lower headlights arranged. The drivers themselves are thereby advantageously facilitated to steer the vehicle in the event of fog, so that the journey can take place at a reduced speed, but with greater safety and less fatigue.

Es versteht sich, dass auch mehr Stromversorgungsstellen einschliesslich ihrer Kreisleitungen und Gruppen von Lichtsignalvorrichtungen mit einer gemeinsamen Photozellen-Steuerung verbunden werden können. Umgekehrt können sich von einer Stromversorgungsstelle mehrere Kreisleitungen zur Verbindung mit Lichthinweismitteln abzweigen. Ausserdem kann jede Stromversorgungsstelle in an sich bekannter Weise mit selbständigen Stromerzeugern versehen sein, oder aber an eine gemeinsale Hauptstrom - leitung angeschlossen sein, in welchem Fall sie lediglich als Stromverteilungsstelle wirkt. Darüber hinaus kann jede Stromversorgungsstelle in an sich bekannter Weise mit von den Photozellen-Steuerungen unabhängigen zusätzlichen Steuermitteln für die Stromversorgung ver sehen sein. Damit ist es möglich, nach Abtrennen der Photozellen-Steuerungen von der betreffenden Kreisleitung die Stromversorgung über eben diese Kreisleitung durch die zusätzlichen Steuermittel ein- bzw. auszuschalten. Dadurch können die Lichtsignalvorrichtungen auch ohne Nebel z.B, zur Erleichterung des Strassenver kehrs bei Nacht in Betrieb gesetzt werden.It goes without saying that more power supply points, including their circular lines and groups of light signal devices, can be connected to a common photocell control. Conversely, several circuit lines can branch off from a power supply point for connection to light indication means. In addition, each power supply point can be provided with independent power generators in a manner known per se, or else can be connected to a common main power line, in which case it merely acts as a power distribution point. In addition, each power supply point can be seen in a manner known per se with additional control means for the power supply that are independent of the photocell controls. This makes it possible, on or after separation of the photocell controls of the respective district administration power over these same K tear line by the additional control means off. As a result, the light signal devices can also be operated without fog, for example, to facilitate road traffic at night.
