Description

Die Erfindung betrifft eine Vorrichtung zur Weiterübermittlung von von ihr empfangenen, von einer Zentrale oder Erfassungseinheit gesendeten, ein Verkehrsnetz betreffenden Verkehrsinformationen an mindestens ein Endgerät.The invention relates to a device for the transmission of it received, sent from a central office or registration unit Traffic information relating to the traffic network to at least one terminal.

Eine derartige Vorrichtung kann im Verkehrstelematikbereich verwendet werden, um Verkehrsinformationen, welche eine Zentrale aussendet, an Verkehrstelematik-Endgeräte weiterzuübermitteln, welche sich in Fahrzeugen befinden. Auch können durch eine derartige Vorrichtung Verkehrsinformationen, welche von die Fahrzeugdichte, Fahrzeugzahlen oder Geschwindigkeiten etc. detektierenden Erfassungseinheiten an Straßen etc. erfaßt werden und an die Vorrichtung ausgesandt werden, per Funk an Fahrzeuge weiterübermittelt werden.Such a device can be used in the area of traffic telematics Traffic information that a control center sends out to traffic telematics terminals to forward which are in vehicles. Can too through such a device traffic information, which from the Detect vehicle density, vehicle numbers or speeds etc. Detection units on roads etc. can be detected and on the device be sent out, transmitted to vehicles by radio.

In Großbritannien zur Weiterübermittlung von Verkehrsinformationen verwendete Vorrichtungen, welche an Straßen angeordnet sind und von einer Verkehrszentrale gesendete Verkehrsinformationen an passierende Fahrzeuge weiterübermitteln, bedingen einen erheblichen Montageaufwand und geringe Flexibilität. Insbesondere ist die Stromversorgung an Autobahnen und/oder Landstraßen wegen häufig nicht vorgesehener Netzstromversorgung problematisch. Jedoch ist auch bei vorhandener Netzstromversorgung die Montage relativ aufwendig. Ferner weisen die verwendeten Vorrichtungen ein hohes Gewicht und einen erheblichen Platzbedarf auf.Used in the UK to transmit traffic information Devices arranged on roads and from a traffic center forward transmitted traffic information to passing vehicles, require considerable assembly effort and little flexibility. Especially the power supply on motorways and / or country roads is often not intended mains power supply problematic. However, even if there is one Mains power supply assembly relatively complex. Furthermore, the used Devices have a high weight and a significant amount of space.

Hinsichtlich der Stromversorgung ist die Möglichkeit der Versorgung von Sende- und Empfangseinrichtungen mit batteriegepufferter Solarstromversorgung bereits bekannt. Dabei werden Solarelemente auf eigenen Masten neben der Straße etc. angebracht und eine Batteriepufferung, erforderliche Rechner, Auswerteinheiten, Sende- und Empfangsvorrichtungen in einem separaten Gehäuse angeordnet. Bei der Montage von Solarelementen auf Masten neben der Straße etc. sind eigene Fundamente für die Masten und für die Gehäuse für die Batteriepufferung, Rechner, Sende- und Empfangseinrichtungen erforderlich. Ferner müssen Kabel vom Gehäuse für den Rechner usw. zu einer Sende- bzw. Empfangseinrichtung gelegt werden. Diese können eine Sabotage durch Durchschneiden der Kabel anregen. Problematisch ist ferner, daß ein Verlegen der gesamten Vorrichtung an eine andere Position, welche beispielsweise wegen andauernder Bauarbeiten an der bisherigen Position der Vorrichtung erforderlich sein kann, aufwendig und damit teuer ist. Diese Lösung ist also teuer, unsicher und unflexibel.Regarding the power supply, the possibility of supplying transmission and Receiving devices with battery-backed solar power supply are already known. Solar elements are attached to their own masts next to the street etc. and a battery backup, necessary computers, evaluation units, transmit and Receiving devices arranged in a separate housing. During installation of solar elements on masts next to the road etc. are separate foundations for the masts and for the housings for battery backup, computers, transmitters and Receiving facilities required. Furthermore, cables from the housing for the Computers etc. are placed in a transmitting or receiving device. This can trigger sabotage by cutting the cables. Is problematic further that moving the entire device to a different position, which for example due to ongoing construction work at the previous position of Device may be required, complex and therefore expensive. This solution is So expensive, unsafe and inflexible.

Hiervon ausgehend ist die Aufgabe der Erfindung, eine Vorrichtung zu schaffen, welche bei möglichst geringem Montageaufwand kostengünstig, flexibel und möglichst sabotageunanfällig die Weiterübermittlung von von einer Zentrale oder Erfassungseinheit gesendeten Verkehrsinformationen an mindestens ein Endgerät ermöglicht. Die Aufgabe wird durch den Gegenstand des unabhängigen Anspruchs gelöst.Proceeding from this, the object of the invention is to create a device which is inexpensive, flexible and with the least possible assembly effort the transmission of from a central office or, as far as possible, not subject to sabotage Registration unit sent traffic information to at least one terminal enables. The task is subject to the independent claim solved.

Die erfindungsgemäße Vorrichtung ist als bauliche Einheit ausgebildet und damit einfach und kostengünstig montierbar. Da keine Verkabelung von Komponenten der Vorrichtung erforderlich ist, ist eine Sabotage durch Durchschneiden von Kabeln nicht zu erwarten. Auch ein Verlegen der Vorrichtung an eine andere Position ist einfach und kostengünstig möglich, da die Vorrichtung als bauliche Einheit ausgebildet ist; wenn sie an einer Brücke oder einem Gebäude oder einem vorhandenen Mast bzw. Schild montiert wird, ist überdies kein Fundament erforderlich.The device according to the invention is designed as a structural unit and thus easy and inexpensive to assemble. Since no wiring of components of the Device is required, sabotage by cutting cables is not expected. Moving the device to another position is also easy and possible inexpensively, since the device is designed as a structural unit; if they are on a bridge or building or an existing mast or If a shield is installed, no foundation is required.

Um den zur Verfügung stehenden Solarstrom möglichst optimal zu nutzen, weist die Vorrichtung zweckmäßig eine Verarbeitungseinheit auf, welche so programmiert ist, daß aus den über den ersten Kommunikationskanal empfangenen Verkehrsinformationen diejenigen Verkehrsinformationen herausgefiltert und/oder aufbereitet und/oder verarbeitet werden, die für die bezüglich des Standortes der Vorrichtung gerechneten nächsten Streckenabschnitte relevant sind, wobei diese Verkehrsinformationen über den zweiten Kommunikationskanal der Vorrichtung abgestrahlt, also weiterübermittelt werden. In order to make the best possible use of the available solar power, the Device expediently has a processing unit which is programmed in such a way that from those received over the first communication channel Traffic information filtered out and / or those traffic information processed and / or processed for the location of the Device calculated next route sections are relevant, these Traffic information via the second communication channel of the device emitted, i.e. be transmitted on.

Ferner ist es vorteilhaft, wenn das Programm bzw. die Ablaufsteuerung der Vorrichtung so gestaltet ist, daß eine Aktivierung der Vorrichtung bei die Vorrichtung passierenden Fahrzeugen, insbesondere bei die Vorrichtung mit einer ungefähr vorgegebenen Geschwindigkeit oder Mindestgeschwindigkeit passierenden Fahrzeugen erfolgt, wobei lediglich bei einer Aktivierung Verkehrsdaten von der Vorrichtung weiterübermittelt werden.It is also advantageous if the program or the sequence control of the Device is designed so that an activation of the device in the device passing vehicles, especially in the device with an approx predetermined speed or minimum speed passing Vehicles takes place, only when activation of traffic data from the Device be forwarded.

Die Komponenten der Vorrichtungen sind vorzugsweise in einem Gehäuse integriert, was eine besonders kompakte und wettergeschützte Ausbildung erlaubt.The components of the devices are preferably integrated in a housing, which allows a particularly compact and weatherproof training.

Besonders einfach montierbar und sabotageunanfällig ist die Anordnung aller Komponenten der Vorrichtung auf einem gemeinsamen Träger, welcher insbesondere an einem Brückengeländer montierbar sein kann. Dabei können Komponenten der Vorrichtung, insbesondere Solarzellen, am Träger verlaufend angeordnet sein oder alle Komponenten der Vorrichtung z. B. in einem Gehäuse am Ende des Trägers angeordnet sein.The arrangement of all is particularly easy to install and is not susceptible to sabotage Components of the device on a common carrier, which in particular can be mounted on a bridge railing. Components of the Device, in particular solar cells, arranged to extend on the carrier or all components of the device e.g. B. in a housing at the end of the carrier be arranged.

Eine Optimierung der Ausnutzung der zur Verfügung stehenden Solarenergie ist ferner insbesondere durch eine Nachführung der Solarelemente, insbesondere Solarzellen, entsprechend dem Tagesgang der Sonne mittels eines Nachführelementes, insbesondere elektrischen Drehantriebes, möglich.An optimization of the use of the available solar energy is furthermore in particular by tracking the solar elements, in particular Solar cells, according to the daily course of the sun by means of a Tracking element, in particular electrical rotary drive, possible.

Figur 1 zeigt als schematische Übersicht die Übermittlung von Verkehrsinformationen von einer Erfassungseinheit 1 über eine Mobilfunkzentrale (hier GSM-Zentrale) 2 an eine Verkehrstelematikzentrale 3 (= Dienstzentrale für Verkehrstelematik-Daten), über eine hier als Paging-Zentrale ausgebildete Weiterübermittlungszentrale 4 (die beispielsweise auch eine Mobilfunkzentrale, insbesondere Kurznachrichtenzentrale oder/und eine DAB-RDS-TMC oder sonstige Radiozentrale oder Funkzentrale sein kann) an eine erfindungsgemäße Vorrichtung 5 zur Weiterübermittlung von Verkehrsdaten an ein (angedeutetes) Endgerät 6 in einem Fahrzeug 7.Figure 1 shows a schematic overview of the transmission of traffic information from a detection unit 1 via a mobile radio center (here GSM center) 2 a traffic telematics center 3 (= service center for traffic telematics data), about a forwarding center 4 designed here as a paging center (the for example also a mobile radio center, in particular short message center or / and be a DAB-RDS-TMC or other radio center or radio center can) to a device 5 according to the invention for the further transmission of Traffic data to a (indicated) terminal 6 in a vehicle 7.

Von der Erfassungseinheit 1 werden hier Anzahl, Länge und Geschwindigkeiten der Fahrzeuge 8, 9, 10 per Infrarot, Radar etc. gemessen. Daten über diese Werte dieser Fahrzeuge 8, 9, 10 usw. werden (z.B. gebündelt) als Verkehrsdaten an die Mobilfunkzentrale 2 gesendet, wobei hier eine Übertragung der Verkehrsdaten als Kurznachricht (GSM-SMS etc.) erfolgt, jedoch auch per sonstigem Funk etc. möglich ist. Von der Mobilfunkzentrale 2 werden erfaßte Daten an die Verkehrstelematikzentrale 3 weitergeleitet, in welcher auch von anderen Mobilfunkzentralen Daten eingehen können. In der Verkehrstelematikzentrale werden eingehende Verkehrsdaten gebündelt, weiterbearbeitet und selektiert. Insbesondere können in der Verkehrstelematikzentrale Verkehrsanalysen, Verkehrsprognosen, Navigationshinweise etc. für das gesamte Verkehrsnetz oder selektiert für bestimmte Straßen etc. des Verkehrsnetzes erstellt werden. Von der Verkehrstelematikzentrale 3 werden an die Weiterübermittlungszentrale 4 überarbeitete Verkehrsinformationen zum Aussenden an Vorrichtungen 5 (an unterschiedlichen Positionen) übergeben, wobei hier beispielsweise für die Vorrichtung 5 nur Verkehrsinformationen zur Verfügung gestellt werden, welche von der Position der Vorrichtung 5 in Fahrtrichtung entlang einer bestimmten Strecke von Bedeutung sind, wie beispielsweise Staus in Fahrtrichtung hinter der Vorrichtung 5. Beispielsweise kann die Vorrichtung 5 an Fahrzeuge 7 (in der Nähe der Brücke 14) eine Verkehrsinformation senden, wenn im Bereich der Erfassungsheinheit 1 eine Anomalie, wie ein Stau, Unfall etc., detektiert wird. Die Übersendung von Verkehrsinformationen von der Weiterübermittlungszentrale 4 an die Vorrichtung 5 kann beispielsweise per Mobilfunk, insbesondere Mobilfunk-Kurznachricht, Paging, Radio oder andere Funkübertragung erfolgen. Auch ist es möglich, von der Weiterübermittlungszentrale 4, insbesondere per Radio, an Vorichtungen 5 an verschiedenen Orten jeweils Verkehrsmeldungen zu übermitteln, welche nicht nur für die jeweils einzelne Vorrichtung 5 von Bedeutung sind. In diesem Falle ist ein Ausselektieren in der Vorrichtung 5 von empfangenen Verkehrsinformationen hinsichtlich ihrer Relevanz für die Vorrichtung 5 passierende Fahrzeuge, insbesondere hinsichtlich ihrer örtlichen Relevanz, möglich.The number, length and speeds of the acquisition unit 1 are here Vehicles 8, 9, 10 measured by infrared, radar etc. Data about these values this Vehicles 8, 9, 10 etc. are (e.g. bundled) as traffic data to the Cellular center 2 sent, here a transmission of the traffic data as Short message (GSM-SMS etc.) takes place, but also possible via other radio etc. is. Acquired data from the mobile radio center 2 to the Traffic telematics center 3 forwarded in which also by others Mobile radio centers can receive data. In the traffic telematics center incoming traffic data bundled, processed and selected. Especially in the traffic telematics center traffic analyzes, traffic forecasts, Navigation information etc. for the entire transport network or selected for specific ones Roads etc. of the transport network. From the traffic telematics center 3 revised traffic information to the forwarding center 4 handed over to devices 5 (at different positions) for transmission, here, for example, only traffic information for the device 5 Be made available, which depends on the position of the device 5 in the direction of travel along a certain route, such as traffic jams in Direction of travel behind the device 5. For example, the device 5 can be on Vehicles 7 (near the bridge 14) send traffic information if in Area of the detection unit 1 detects an anomaly, such as a traffic jam, accident, etc. becomes. The sending of traffic information from the Forwarding center 4 to the device 5 can for example by Mobile radio, in particular mobile radio short message, paging, radio or others Radio transmission takes place. It is also possible from the forwarding center 4, in particular by radio, on devices 5 at different locations To transmit traffic reports, which not only for the individual Device 5 are important. In this case a selection is in the Device 5 of received traffic information with regard to its relevance for vehicles passing the device 5, in particular with regard to their location Relevance, possible.

Die Weitervermittlung über den zweiten Kommunikationskanal (12) kann per Funk, insbesondere UHF, KW, MW oder LW, erfolgen. Die Übermittlung erfolgt insbesondere durch Paging, Funkruf, z.B. mittels RPC/No. 1 oder Pocsag oder Flex-Standard.The transfer via the second communication channel (12) can be carried out by radio, especially UHF, KW, MW or LW. The transmission takes place especially by paging, paging, e.g. using RPC / No. 1 or Pocsag or Flex standard.

Die Vorrichtung 5 weist zur Energieversorgung Solarelemente und eine Batteriepufferung aus. Um die begrenzte zur Verfügung stehende Solarenergie auszunutzen, sind verschiedene Energiesparmöglichkeiten vorsehbar. Insbesondere kann ein Selektieren von in die Vorrichtung über deren Empfangseinrichtung eingehenden, über einen ersten funkbasierten Kommunikationskanal 11 (zwischen 4 und 5) übermittelten Verkehrsinformationen aus der Verkehrstelematikzentrale 3 hinsichtlich Relevanz, insbesondere örtlicher Relevanz für die Vorrichtung 5 passierende Fahrzeuge erfolgen, so daß die zu sendende Datenmenge und damit die erforderliche Sendeenegie in der Vorrichtung 5 verringert wird. Ferner ist es möglich, daß die Vorrichtung 5 nur dann sendet, wenn sie detektiert, daß Fahrzeuge sie passieren. Insbesondere kann eine Aufweckzone 13 vor der Vorrichtung 5 vorgesehen sein. Wenn ein Fahrzeug die Aufweckzone passiert, kann die Vorrichtung 5 aufgeweckt werden, also zum Weiterübermitteln von empfangenen Verkehrsinformationen über den zweiten funkbasierten Kommunikationskanal zu Fahrzeugen 6 veranlaßt werden. (Die Detektion von die Vorrichtung 5 passierenden Fahrzeugen kann durch Infrarot-Detektion, Wärmestrahlungs-Detektion, Radar etc. erfolgen.)The device 5 has solar elements and a for energy supply Battery backup off. To the limited available solar energy To exploit, various energy saving options are foreseeable.
