Abstract

The system includes information detectors placed at specific positions along a travel path and connected to a transmitter-receiver. The detectors transmit information in a predetermined time frame to a central receiver for preparation and broadcasting. The transceivers transmit data of the information detectors individually in a bucket chain cycle. Each message telegram relayed to the next station is expanded by the message segment belonging to the station which is relaying the message telegram. Operation of vehicle components, e.g. air bags, belt sensors, and indicators may lead to the sending of a telegram to the fixed transmitter-receiver. Alternatively, sensors in a vehicle, e.g. for speed, rpm, ignition on etc., may be collected to determine a driving state. The status signal is transmitted to the fixed transmitter-receiver and then passed on to a central station for evaluation together with information on other vehicles.

Description

Die Erfindung bezieht sich auf ein System zum Erfassen von längs vorgegebener Verkehrswege ermittelter Informationen und Übertragen der Informationen an zentrale Stellen.The invention relates to a system for acquiring information determined along predetermined traffic routes and transmitting the information to central locations.

Die Informationen der Verkehrsteilnehmer über Verkehrszustände, beispielsweise Verkehrsdichte und Wegezustand, lokale Wetterbedingungen, Notfalle und dergl. ist meist unzureichend und nicht aktuell. Solche Informationen werden bisher von verschiedenen Institutionen ohne Systematik und mit zum Teil geringem Aktualitätsgrad durch Verkehrspolizei, Abschleppdienste, Personal von Autofahrervereinigungen und Verkehrsfunksendern aufgenommen und weitergegeben.The information provided by road users about traffic conditions, for example traffic density and road conditions, local weather conditions, emergencies and the like, is usually inadequate and not up to date. Up to now, such information has been received and passed on by various institutions without systematics and sometimes with a low degree of topicality by traffic police, towing services, staff from motorists' associations and traffic radio stations.

Der Erfindung liegt die Aufgabe zugrunde, eine Lösung anzugeben, mit der aktuelle, auf Wunsch jederzeit abrufbare Informationen für Verkehrsteilnehmer angeboten und vorhandene Informationssysteme dabei weitestgehend genutzt werden können.The invention is based on the object of specifying a solution with which current information, which can be called up at any time if desired, is offered to road users and existing information systems can be used as far as possible.

Diese Aufgabe wird mit einem System der eingangs beschriebenen Art gemäß der Erfindung gelöst durch an den betreffenden Stellen angeordnete Informationserfasser, die an im entsprechenden räumlichen Raster angeordnete Sender angeschlossen sind, die die Informationen in einem vorbestimmten Zeitraster an einen zentralen Empfänger senden zur Aufbereitung und Verbreitung.This object is achieved with a system of the type described at the outset according to the invention by information collectors arranged at the relevant points and connected to transmitters arranged in the corresponding spatial grid, which send the information to a central receiver in a predetermined time grid for processing and distribution.

Mit dem erfindungsgemäßen System, das mittels Meßwerterfassern für Wegezustand, Verkehrsstatus, Wetterbedingungen, Notfälle etc. aktuelle Informationen zur Verkehrslage sammelt und an Zentralen weiterleitet, die ihrerseits diese Informationen aufbereiten und wieder verbreiten, ist eine optimale Verkehrsinformationen und -leitung möglich.With the system according to the invention, which collects and receives current information on the traffic situation by means of measured value recorders for road condition, traffic status, weather conditions, emergencies etc. Forwarding control centers, which in turn process and distribute this information, an optimal traffic information and management is possible.

Vorteilhafte Ausgestaltungen und Weiterbildungen des Erfindungsgegenstandes sind in den Unteransprüchen angegeben.Advantageous refinements and developments of the subject matter of the invention are specified in the subclaims.

Nachstehend wird die Erfindung anhand von zwei in der Zeichnung dargestellten Ausführungsbeispielen, die jeweils ein Meldungssammel- und -transportsystem zeigen, näher erläutert.The invention is explained in more detail below with reference to two exemplary embodiments shown in the drawing, each of which shows a message collection and transport system.

Fig. 1 zeigt ein Meldungssammel- und -transportsystem von der Art multipoint to point. Dabei sind längs eines Fahrweges, auf dem sich ein mit einem Mobiltelefon MT und einem Rundfunkempfänger R ausgestattetes Fahrzeug befindet, insbesondere an neuralgischen Strecken, in bestimmten Abstanden Informationserfasser IE angeordnet, die für sich vollkommen autark sind. Sie werden in einem bestimmten Raster verteilt und nehmen zu bestimmten Zeiten Informationen auf. Dies kann aktiv oder passiv mittels elektromagnetischer, optischer, akustischer, elektrischer, magnetischer oder anderer physikalischer Effekte erfolgen. Zur Übertragung dieser Informationen hat das System zwei Ebenen, nämlich eine Einzelinformationsebene und eine Sammelinformationsebene.1 shows a message collection and transport system of the multipoint to point type. Here, along a route on which a vehicle equipped with a mobile phone MT and a radio receiver R is located, in particular on sensitive routes, information detectors IE are arranged at certain intervals which are completely self-sufficient. They are distributed in a certain grid and record information at certain times. This can be done actively or passively by means of electromagnetic, optical, acoustic, electrical, magnetic or other physical effects. The system has two levels for the transmission of this information, namely an individual information level and a collective information level.

Zunächst wird die Einzelinformationsebene näher betrachtet. Hierbei werden in Abständen von ca. 100 m bis 1 km Sender S am Verkehrsträgerrand, z.B. Straße, Fluß, Bahnstrecke aufgestellt. An diese Sender ist/sind jeweils der/die Informationserfasser IE angeschlossen, deren Inhalt weitergeleitet werden soll. Die Sender S senden die Informationen der an sie angeschlossenen Informationserfasser IE in einem vorbestimmten Zeitraster an einen zentralen Empfänger E, der alle Sender S in diesen jeweils zugeordneten vorbestimmten Zeitabschnitten empfangt. Dabei ergibt sich, daß die Sender zum Teil mit hoher Sendeleistung senden müssen, da ihre Position weit entfernt und ohne Sichtverbindung zum zentralen Empfänger E sein kann.First, the individual information level is considered in more detail. In this case, transmitters S are set up at intervals of approx. 100 m to 1 km at the edge of the mode of transport, for example road, river, railway line. The information collector (s) whose content is to be forwarded is / are connected to these transmitters. The transmitters S send the information of the information collectors IE connected to them in a predetermined time frame to a central receiver E, which receives all transmitters S in these respectively assigned predetermined time segments. The result of this is that some of the transmitters have a high transmission power must send, since their position can be far away and without line of sight to the central receiver E.

Es ist daher vorteilhaft, daß die Sender S zusätzlich jeweils einen Empfänger E enthalten, der in einem vorbestimmten Zeitabschnitt die Sendung des benachbarten Senders empfängt und in einem zweiten Zeitabschnitt die Nachricht wieder aussendet, die dann von dessen Nachbarn empfangen wird, der diese Nachricht in einem dritten Zeitabschnitt wieder aussendet. Das Weiterreichen von Sendeempfänger S/E zu Sendeempfänger S/E wird fortgesetzt, bis die Nachricht in einem n-ten Zeitabschnitt beim zentralen Empfänger E angelangt ist (Eimerkettenprinzip). Die Sendeempfänger S/E haben jeweils zu ihren nächsten Nachbarn in der Eimerkette Sichtverbindung. Beim Durchreichen von Sendeempfänger zu Sendeempfänger können die an die Sendeempfänger S/E jeweils angeschlossenen Sensoren (Informationserfasser) IE ihre Daten in das Meldungstelegramm einfügen. Ein solches System von der Art point to point to end ist in Fig. 2 dargestellt.It is therefore advantageous that the transmitters S each additionally contain a receiver E, which receives the transmission of the neighboring transmitter in a predetermined time period and sends the message again in a second time period, which is then received by its neighbors, who receive this message in one sends out the third period again. The forwarding from transceiver S / E to transceiver S / E continues until the message arrives at the central receiver E in an nth time segment (bucket chain principle). The transceivers S / E each have line of sight to their nearest neighbors in the bucket chain. When passing from transceiver to transceiver, the sensors (information collectors) IE connected to the transceivers S / E can insert their data into the message telegram. Such a system of the type point to point to end is shown in FIG. 2.

Die Länge der jeweiligen Eimerkette kann sehr verschieden sein. Die Bestimmung einer Maximallänge des Sammeltelegramms als Standard führt zu einer immer gleichen und unter Umständen sehr langen Übertragungsdauer. Es ist daher sehr vorteilhaft, wenn je Sendeempfänger S/E der Datensatz der angeschlossenen Sensoren individuell in einem eigenen Eimerkettenzyklus übertragen wird.The length of the respective bucket chain can be very different. The determination of a maximum length of the collective telegram as a standard always leads to the same and, under certain circumstances, very long transmission times. It is therefore very advantageous if the data record of the connected sensors is transmitted individually in a separate bucket chain cycle for each transceiver S / E.

In einer weiteren vorteilhaften Ausgestaltung des Systems ist vorgesehen, daß das Meldungstelegramm bei jedem Weitersenden zur nächsten Station um den Meldungsteil verlängert wird, der zu dieser absendenden Station gehört. Damit benötigen kurze Eimerketten kurze Übertragungszeiten, lange dagegen entsprechend längeren Übertragungszeiten. Zu Beginn des Empfangszeitschlitzes wird der Empfänger für kurze Zeit (Bruchteil einer Telegrammlänge) zwangseingeschaltet; ist ein Signal vorhanden, wird der Empfänger empfangsbereit gehalten und schaltet sich ab, sobald das Empfangseingangssignal verschwindet.In a further advantageous embodiment of the system it is provided that the message telegram is extended each time it is forwarded to the next station by the message part that belongs to this sending station. Short bucket chains therefore require short transmission times, while long ones require correspondingly longer transmission times. At the beginning of the reception time slot, the receiver is switched on for a short time (fraction of a telegram length); there is a signal the receiver is kept ready to receive and switches off as soon as the received input signal disappears.

Bei der Sammelinformationsebene sind eine oder mehrere Eimerketten an einen zentralen Empfänger E angeschlossen. Dieser sammelt die Informationen und gibt sie an ein zweites Informationssystem M mit einer Basisstation BS ab, das ein öffentliches (PLMN) oder privates Mobilfunksystem, ein Betriebsfunksystem (BFS), ein Verkehrsfunksystem etc. sein kann (vgl. Fig. 2). Voraussetzung ist hierbei lediglich, daß das Informationssystem datenübertragungsfähig ist. Die Zentrale dieses übergeordneten Systems wertet die Daten aus und verteilt sie an die Verkehrsteilnehmer, z.B. über ein drittes rundfunkartiges Informationssystem (RS) oder über das vorgenannte Mobilfunksystem, Betriebsfunksystem etc.At the collection information level, one or more bucket chains are connected to a central receiver E. This collects the information and delivers it to a second information system M with a base station BS, which can be a public (PLMN) or private mobile radio system, a company radio system (BFS), a traffic radio system, etc. (see FIG. 2). The only requirement is that the information system is capable of data transmission. The control center of this higher-level system evaluates the data and distributes it to road users, e.g. via a third broadcast-type information system (RS) or via the aforementioned mobile radio system, company radio system etc.

Durch günstige Wahl der Sende-Empfangszeitabschnitte wird erreicht, daß lediglich eine einzige Frequenz für alle Sendeempfänger S/E aller Eimerketten erforderlich ist, da die Sendeleistungen wegen der vorhandenen Sichtverbindung so gering sein können, daß bei gleicher Frequenz derselbe Zeitabschnitt nach wenigen Kilometer Entfernung wieder verwendet werden kann.A favorable choice of the transmission-reception periods ensures that only a single frequency is required for all transceivers S / E of all bucket chains, since the transmission powers can be so low due to the existing line of sight that the same period of time can be used again after a few kilometers at the same frequency can be.

Die Sendeempfänger S/E werden vorteilhaft mit den Informationserfassern (Sensoren, Bildaufnehmer ...) integriert und von einem Solargenerator gespeist. Alle Funktionen, die nicht zu bestimmten Zeiten gebraucht werden, schaltet eine Zeitschaltuhr, die jedem Sendeempfänger zugeordnet ist, ab. Die Uhren aller Sendeempfänger sind synchronisiert, beispielsweise durch ein gemeinsames hochgenaues Funksignal. Die Uhr steuert ebenfalls alle zeitlichen Abläufe der Sendeempfänger S/E und des zentralen Empfängers E.The S / E transceivers are advantageously integrated with the information recorders (sensors, image recorders ...) and fed by a solar generator. A timer that is assigned to each transceiver switches off all functions that are not used at certain times. The clocks of all transceivers are synchronized, for example by a common high-precision radio signal. The clock also controls all the time sequences of the transceiver S / E and the central receiver E.

Jeder Berechtigte kann entsprechend dem Umfang seiner Berechtigung die Informationen der Sendeempfänger, der zentralen Empfänger oder des übergeordneten Systems abrufen. Die übertragenen Informationen können Statusmeldungen von Sensoren, Bilddaten von Kameras, Meldungen von Notruftasten etc. sein.According to the scope of their authorization, each authorized person can access the information of the transceiver, the central Get the recipient or the parent system. The information transmitted can be status messages from sensors, image data from cameras, messages from emergency call buttons, etc.

Bei dem System können die Fahrzeuge ebenfalls zeitsynchrone Sender benutzen. Mit Betätigung der Warnblinkanlage, des Airbags, der Gurtsensoren oder einer Notfalltaste wird ein Telegramm zu den fest installierten Sendeempfangs-Einheiten S/E geschickt. Diese hören in einem überall gleichen Zeitschlitz periodisch auf solche Notfalltelegramme Der Inhalt kann sein: Fahrzeugkennzeichen, Notfalltaste betätigt und/oder Airbag, Gurtsensor, Warnblinker o.ä. ausgelöst. Der zentrale Empfänger E erhält nach Durchlauf der Eimerkette diese Information, fügt die Ortsinformation und die Uhrzeit zu und übergibt an das übergeordnete System, das die Information an das Servicecenter SC weiterleitet. Wenn ein Fahrzeug zusätzlich einen zeitsynchronen Empfänger besitzt, kann die Notfallmeldung eines anderen Fahrzeugs auch längs der gefahrenen Strecke abgehört werden, auf der die Notfallmeldung gerade im Eimerkettenverfahren transportiert wird.With the system, the vehicles can also use time-synchronous transmitters. When the hazard warning system, airbag, belt sensors or an emergency button is actuated, a telegram is sent to the permanently installed S / E transceiver units. These periodically listen to such emergency telegrams in the same time slot everywhere. The content can be: vehicle registration number, emergency button actuated and / or airbag, belt sensor, hazard lights or similar. triggered. After passing through the bucket chain, the central receiver E receives this information, adds the location information and the time and passes it on to the higher-level system, which forwards the information to the service center SC. If a vehicle also has a time-synchronous receiver, the emergency message from another vehicle can also be listened to along the route traveled, on which the emergency message is currently being transported using the bucket chain method.

Der zentrale Empfänger (Kästchen A in Fig. 2) kann auch zusätzlich mit einem Sender ausgerüstet sein (strichliert umrandetes Kästchen B in Fig. 2). Dann können auch beliebige Meldungen, die für die jeweilige Strecke interessant sind, per Eimerkette zu den Fahrzeugen übertragen werden. Dies erfolgt in einem anderen Zeitzyklus und mit umgekehrter Zeitfolge, so daß sich die Nachricht vom zentralen Sendeempfänger wegbewegt.The central receiver (box A in FIG. 2) can also be additionally equipped with a transmitter (box B outlined in dashed lines in FIG. 2). Then any messages that are interesting for the respective route can also be transmitted to the vehicles via bucket chains. This takes place in a different time cycle and with a reverse time sequence, so that the message moves away from the central transceiver.

In vorteilhafter Ausgestaltung des Systems ist ferner vorgesehen, daß zu bestimmten Zeiten von jeder Sendeempfang-Station S/E anstelle einer Meßwertmeldung ein Testtelegramm verschickt wird, um die Funktion der Eimerkette bzw. der Sendeempfänger zu prüfen und mögliche Defekte zu lokalisieren.In an advantageous embodiment of the system it is also provided that a test telegram is sent from each transceiver station S / E at certain times instead of a measured value message in order to check the function of the bucket chain or the transceiver and to localize possible defects.

Sensoren im Fahrzeug können Meldungen über Geschwindigkeit, Motordrehzahl, "Zündung Ein", etc. zu einer Fahrzustandssituation zusammenfassen, die zu den fest installierten Sendeempfänger-Einheiten geschickt und zur Zentralstation weitergereicht werden, wo sie zusammen mit den Informationen anderer Fahrzeuge ausgewertet werden.Sensors in the vehicle can summarize messages about speed, engine speed, "ignition on", etc. into a driving state situation, which are sent to the permanently installed transceiver units and passed on to the central station, where they are evaluated together with the information from other vehicles.
