Description

Technisches GebietTechnical field

Die Erfindung betrifft eine Überwachungsanlage zur Überwachung des Verkehrs im Bereich von Wechselverkehrszeichen, bei welcher der Parameter der Überwachungsanlage bei Umschaltung der Wechselverkehrszeichen entsprechend umschaltbar ist.The invention relates to a monitoring system for monitoring traffic in the Range of variable message signs where the parameter of the Monitoring system when changing the variable message signs accordingly is switchable.

Verkehrszeichen sollen ein bestimmtes Verhalten von Verkehrsteilnehmern vorschreiben, beispielsweise eine zulässige Höchstgeschwindigkeit oder ein Überholverbot. Es gibt "Wechselverkehrszeichen", deren Angaben, z.B. eine Geschwindigkeitsangabe, veränderbar sind. Damit können z.B. die zulässigen Höchstgeschwindigkeiten in Abhängigkeit von der jeweiligen Verkehrssituation verändert werden. Bei geringer Verkehrsdichte können höhere Geschwindigkeiten zugelassen werden als bei hoher Verkehrsdichte. Geschwindigkeitsbeschränkungen können ggf. nur zu bestimmten Zeiten, bei einer bestimmten Verkehrsdichte oder bei schlechten Sichtverhältnissen vorgesehen werden. Solche Wechselverkehrszeichen werden insbesondere vorgesehen in Verbindung mit "Verkehrsbeeinflussungsanlagen". Die Wechselverkehrszeichen erhalten dann Kommandos von einer zentralen Verkehrsbeeinflussungsanlage nach einem "TLS-Protokoll" (TLS = Technische Lieferbedingungen Streckenstationen), also in Abhängigkeit von bestimmten standardisierten Steuersignalen. Traffic signs should prescribe a certain behavior of road users, for example, a permissible maximum speed or a no overtaking. There are "Variable message sign", the details of which, e.g. a speed indication, are changeable. With this e.g. the permissible maximum speeds in Dependent on the respective traffic situation. With less Traffic densities can be permitted at higher speeds than at high speeds Traffic density. Speed restrictions may only apply to certain ones Times, with a certain traffic density or with poor visibility be provided. Such variable message signs are provided in particular in Connection with "traffic control systems". Get the variable message signs then commands from a central traffic control system according to a "TLS protocol" (TLS = Technical Delivery Conditions for Line Stations), i.e. in Dependence on certain standardized control signals.

Stand der TechnikState of the art

Es sind weiterhin "Verkehrsüberwachungsanlagen" bekannt. Das sind Überwachungsanlagen, welche die Einhaltung der Verkehrsregeln, also etwa die Einhaltung einer vorgeschriebenen Höchstgeschwindigkeit, überwachen sollen. Solche Überwachungsanlagen enthalten einen Meßsensor, der auf die zu überwachende Größe, z.B. die Geschwindigkeit des Fahrzeugs, anspricht. Der Überwachungsanlage wird ein "Parameter", hier die zulässige Höchstgeschwindigkeit, vorgegeben. Die von dem Meßsensor gemessene Geschwindigkeit eines überwachten Fahrzeugs wird mit dieser zulässigen Höchstgeschwindigkeit verglichen. Wenn die zulässige Höchstgeschwindigkeit überschritten wird, wird von einer Kamera eine Aufnahme des Fahrzeugs gemacht, wobei auf dieser Aufnahme oder in fester Zuordnung zu dieser die gemessene Fahrzeuggeschwindigkeit registriert wird. Diese Aufnahme liefert dann einen Beweis für die Übertretung der Verkehrsregeln."Traffic monitoring systems" are also known. These are Monitoring systems that ensure compliance with traffic rules, such as the Compliance with a prescribed maximum speed. Such Monitoring systems contain a measuring sensor that is based on the size to be monitored, e.g. the speed of the vehicle. The surveillance system becomes a "Parameter", here the permissible maximum speed, is specified. The one from that Measuring sensor measured speed of a monitored vehicle is with this permissible maximum speed compared. If the allowable Speed is exceeded, a camera will take a picture of the Vehicle made, which on this recording or in fixed assignment to this measured vehicle speed is registered. This recording then provides one Evidence of violation of traffic rules.

Wenn eine solche Überwachungsanlage in Verbindung mit einem Wechselverkehrszeichen, etwa einer Verkehrsbeeinflussungsanlage, eingesetzt wird, muß der in der Überwachungsanlage vorgegebene Parameter, an die Angabe des Wechselverkehrszeichens angepaßt werden. Wenn beispielsweise an dem Wechselverkehrszeichen die Geschwindigkeitsangabe "100" (km/h) umgeschaltet wird auf "120", dann muß dementsprechend auch in der Überwachungsanlage der Parameter "zulässige Höchstgeschwindigkeit" von 100 km/h auf 120 km/h umgeschaltet werden.If such a monitoring system in connection with a Variable message signs, such as a traffic control system, must be used the parameter specified in the monitoring system, to the specification of the Variable message sign can be adjusted. For example, if the Variable message sign the speed indication "100" (km / h) is switched to "120", the parameter must also be set accordingly in the monitoring system "permissible maximum speed" can be switched from 100 km / h to 120 km / h.

Zu diesem Zweck ist bei bekannten Anlagen dieser Art das TLS-Steuersignal von der Verkehrsbeeinflussungsanlage außer auf das Wechselverkehrszeichen auch auf die Überwachungsanlage aufgeschaltet und bewirkt in dieser die entsprechende Umschaltung des Parameters "zulässige Höchstgeschwindigkeit".For this purpose, the TLS control signal from the Traffic control system in addition to the variable message sign also on the Monitoring system switched on and causes the corresponding switchover of the parameter "permissible maximum speed".

Das ist in verschiedener Hinsicht nachteilig. Einmal muß eine Schnittstelle an der Verkehrsbeeinflussungsanlage zur Übertragung des TLS-Signals an die Überwachungsanlage vorgesehen sein. Es muß eine Verbindung von dieser Schnittstelle zu der Überwachungsanlage hergestellt werden. Das ist nachteilig bei Überwachungsanlagen, die nicht fest installiert sind sondern im fliegenden Einsatz nur vorübergehend mit einer bestimmten Verkehrsbeeinflussungsanlage benutzt werden. Die Überwachungsanlage arbeitet nur mit einer Verkehrsüberwachungsanlage, die nach dem TLS-Protokoll arbeitet. Mit anderen Verkehrsbeeinflussungsanlagen oder Wechselverkehrszeichen ist die Überwachungsanlage nicht einsetzbar. Bei der parallelen Ansteuerung von Verkehrsbeeinflussungs- und Verkehrsüberwachungsanlage könnte auch strittig sein, ob tatsächlich beide Anlagen durch das gleiche TLS-Signal auch auf die gleiche zulässige Höchstgeschwindigkeit geschaltet wurden.This is disadvantageous in several ways. An interface at the Traffic control system for transmission of the TLS signal to the Monitoring system may be provided. There must be a connection from this interface to the surveillance system. That is disadvantageous in Surveillance systems that are not permanently installed but only in flight temporarily used with a specific traffic control system. The Monitoring system only works with a traffic monitoring system that according to the TLS protocol works. With other traffic control systems or The monitoring system cannot be used for variable message signs. With the parallel Control of traffic control and traffic monitoring system could also be controversial as to whether both systems actually have the same TLS signal the same permissible maximum speed were switched.

Offenbarung der ErfindungDisclosure of the invention

Der Erfindung liegt die Aufgabe zu Grunde, eine Überwachungsanlage der eingangs genannten Art so auszubilden, daß zur Ansteuerung der Überwachungsanlage kein Eingriff in die Verkehrsbeeinflussungsanlage erforderlich ist.The invention is based on the object of a monitoring system at the beginning mentioned type so that no to control the monitoring system Intervention in the traffic control system is required.

Der Erfindung liegt weiter die Aufgabe zu Grunde, bei einer Überwachungsanlage der eingangs genannten Art beweisbar zu gewährleisten, daß die Überwachungsanlage bei nur bei Verstoß gegen ein Gebot des Wechselverkehrszeichens anspricht, das tatsächlich auch an dem Wechselverkehrszeichen angegeben ist, beispielsweise der Überschreitung derjenigen Höchstgeschwindigkeit, die an dem Wechselverkehrszeichen gezeigt wird.The invention is further based on the object in a monitoring system provable to ensure that the surveillance system at only addresses a violation of a variable message sign that actually is also indicated on the variable message sign, for example the crossing the maximum speed shown on the variable message sign.

Erfindungsgemäß werden diese Aufgaben gelöst, durch eine das Wechselverkehrszeichen beobachtende Videokamera und bildverarbeitende Mittel zur Erkennung der jeweiligen Angabe des Wechselverkehrszeichens, wobei die Umschaltung des Parameters der Überwachungsanlage nach Maßgabe der so erkannten Angabe erfolgt.According to the invention, these tasks are solved by a variable message sign observing video camera and image processing means for recognizing the respective Indication of the variable message sign, the switchover of the parameter of Monitoring system takes place in accordance with the information thus recognized.

Auf diese Weise ist keine Leitungsverbindung zwischen dem Wechselverkehrszeichen und der Überwachungsanlage erforderlich. Die Überwachungsanlage ist autonom und kann auch im fliegenden Betrieb eingesetzt werden. Das Steuersignal zur Umschaltung der Überwachungsanlage auf einen neuen Parameter, z.B. eine neue Höchstgeschwindigkeit, wird aus dem Videobild des Wechselverkehrszeichens selbst erzeugt. Es wird dadurch sichergestellt, daß diese Umschaltung jeweils zuverlässig nach Maßgabe der Angaben des Wechselverkehrszeichens erfolgt.In this way there is no line connection between the variable message sign and the monitoring system required. The surveillance system is autonomous and can also be used in flight. The control signal for switching the monitoring system to a new parameter, e.g. a new Top speed, is from the video image of the variable message sign itself generated. This ensures that this switchover is always reliable The information on the variable message sign is given.

Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Embodiments of the invention are the subject of the dependent claims.

Ein Ausführungsbeispiel der Erfindung ist nachstehend unter Bezugnahme auf die zugehörige Zeichnung näher erläutert.An embodiment of the invention is below with reference to the associated drawing explained in more detail.

Kurze Beschreibung der ZeichnungBrief description of the drawing

Die Zeichnung ist ein Blockschaltbild und zeigt schematisch eine Anlage zur Verkehrsbeeinflussung mit einem Wechselverkehrszeichen und eine Anlage zur Verkehrsüberwachung.The drawing is a block diagram and shows schematically a system for Traffic control with a variable message sign and an attachment to Traffic monitoring.

Bevorzugtes AusführungsbeispielPreferred embodiment

Eine Verkehrsbeeinflussungsanlage 10 steuert ein Wechselverkehrszeichen 12, das hier eine zulässige Höchstgeschwindigkeit vorgibt. Das Wechselverkehrszeichen 12 wird über ein Kabel 14 durch standardisierte Steuersignale nach einem TLS-Protokoll angesteuert.A traffic control system 10 controls a variable traffic sign 12, which here specifies a permissible maximum speed. The variable message sign 12 is about a cable 14 driven by standardized control signals according to a TLS protocol.

Eine Anlage 16 zur Verkehrsüberwachung soll Verstöße gegen die von dem Wechselverkehrszeichen angegebenen Gebote, also hier die Überschreitung der angegebenen Höchstgeschwindigkeit feststellen und dokumentieren. Zu diesem Zweck enthält die Anlage 16 einen auf die Geschwindigkeit eines überwachten Fahrzeugs ansprechenden Meßsensor 18 und eine Kamera 20. Die Kamera ist auf die Fahrbahn gerichtet und erfaßt das überwachte Fahrzeug. Eine Steuerung 22 erhält in noch zu beschreibender Weise einen Digitalwert, der eine zulässige Höchstgeschwindigkeit wiedergibt. Diese zulässige Höchstgeschwindigkeit wird in bekannter Weise mit dem Geschwindigkeitsmeßwert des Meßsensors 18 verglichen. Wenn die zulässige Höchstgeschwindigkeit von dem überwachten Fahrzeug überschritten wird, wird durch die Steuerung 22 die Kamera 20 ausgelöst. Die Kamera 20 macht dann eine Aufnahme des überwachten Fahrzeugs. Mit dieser Aufnahme werden gleichzeitig die Meßdaten in fester Zuordnung zu der Aufnahme registriert.A system 16 for traffic monitoring should violate the Variable bids indicated bids, so here the exceeding of the Determine and document the specified maximum speed. To this end The system 16 contains one on the speed of a monitored vehicle responsive measuring sensor 18 and a camera 20. The camera is on the road directed and detects the monitored vehicle. A control 22 still receives in descriptively a digital value that has a maximum speed limit reproduces. This permissible maximum speed is known with the Speed measured value of the measuring sensor 18 compared. If the allowable Maximum speed of the monitored vehicle is exceeded by the controller 22 triggered the camera 20. The camera 20 then takes a picture of the monitored vehicle. With this recording the measurement data in fixed assignment to the recording registered.

Das ist bekannte Technik und daher hier nicht im einzelnen beschrieben.This is known technology and is therefore not described in detail here.

Die Anlage 16 zur Verkehrsüberwachung enthält weiterhin eine Beobachtungseinheit 24 zur Beobachtung des Wechselverkehrszeichens 12. Diese Beobachtungseinheit 24 soll nach Maßgabe der tatsächlich von dem Wechselverkehrszeichen angezeigten Angabe, hier "Höchstgeschwindigkeit 80", einen dieser Angabe entsprechenden Digitalwert auf die Steuerung 22 aufschalten. Zu diesem Zweck enthält die Einheit 24 eine Videokamera 26. Die Videokamera wird auf das Wechselverkehrszeichen 12 gerichtet, wie in der Figur durch das Gesichtsfeld 28 angedeutet ist. Die Videokamera 26 erzeugt ein Videobild des Wechselverkehrszeichens 12. Dieses Videobild wird in einem Takt von z.B. 1 sec. digitalisiert, wie durch Block 30 dargestellt ist. Ein Rechner 32 enthält ein Programm zur Zeichenerkennung, z.B. eine OCR-Software, welches in dem digitalisierten Videobild die Ziffern "080" zu erkennen und in digitale Daten umzusetzen vermag. Diese digitalen Daten werden durch eine Steuerung 34 über eine Steuerleitung 36 auf die Steuerung 22 aufgeschaltet, aktivieren die Anlage 16 und werden als "zulässige Höchstgeschwindigkeit" mit dem Geschwindigkeitsmeßwert des Meßsensors verglichen.The system 16 for traffic monitoring also contains an observation unit 24 to observe the variable message sign 12. This observation unit 24 is intended in accordance with the information actually displayed by the variable message sign, here "maximum speed 80", a digital value corresponding to this specification switch on the control 22. For this purpose, the unit 24 contains a video camera 26. The video camera is aimed at the variable message sign 12, as in the figure is indicated by the visual field 28. The video camera 26 generates a video image of the Variable message sign 12. This video picture is in a cycle of e.g. 1 sec. digitized as represented by block 30. A computer 32 contains a program for Character recognition, e.g. an OCR software, which in the digitized video image Can recognize digits "080" and convert them into digital data. This digital Data is transferred to a controller 22 by a controller 34 via a control line 36 activated, activate the system 16 and are called "permissible Maximum speed "compared with the measured speed value of the measuring sensor.

Die digitalisierten Videobilder werden für eine Zeitspanne von z.B. zwei Minuten in einem Speicher 38 gespeichert. Bei Feststellung einer Übertretung werden die Meßdaten und der Zeitpunkt der Messung über die Steuerleitung 36 auf den Speicher 38 geleitet. Zu jeder Übertretung lassen sich dann alle Videobilder des Wechselverkehrszeichens während einer vorgegebenen Zeitspanne vor der Messung festhalten. Damit ist der Zustand des Wechselverkehrszeichens 12 zur Beweissicherung festgehalten. Es kann auch festgestellt werden, ob etwa, was den Fahrer entlasten würde, das Wechselverkehrszeichen 12 unmittelbar vor der Messung seine Angabe etwa von "100" auf "080" geändert hatte.The digitized video images are used for a period of e.g. two minutes in stored in a memory 38. If a violation is found, the measurement data and the time of the measurement is passed via the control line 36 to the memory 38. To Every violation can then all video images of the variable message sign hold for a predetermined period of time before the measurement. So that's the Condition of the variable message sign 12 recorded for preservation of evidence. It can it can also be determined whether, for example, what would relieve the driver Variable message sign 12 immediately before the measurement its indication of approximately "100" changed to "080".

Müssen mehrere Wechselverkehrszeichen beobachtet werden, sind mehrere Beobachtungseinheiten zu kombinieren.If several variable message signs have to be observed, there are several To combine observation units.
