Abstract

The road vehicle (1) has two communication units, one of which can be fixed to the windscreen (11) and contains identification data. The other provides other vehicle condition data (12). Both units are interrogated by a remote station using a defined interrogation procedure. Communication is made via roadside transmitters (2).

Description

Die Erfindung betrifft ein Verfahren zum Austausch von Information zwischen einer Antwortstation eines mobilisierten Teilnehmers am Straßenverkehr, eine Abfragestation, sowie eine zugehörige Abfrage- und Autwortstation.The invention relates to a method for exchanging information between a mobilized subscriber's answering station on the road, an interrogation station, as well as an associated interrogation and word station.

Das vorliegende Beispiel geht aus von einem Plakettensystem, das ursprünglich entwickelt wurde, um per Fernabfrage die Individuen eines zu überwachenden Tierbestands zu identifizieren. Eine Weiterentwicklung dieses Plakettensystems wird bei den europäischen Eisenbahnen zur begleitenden Überwachung von Güterwagen und Frachtcontainern eingesetzt.This example is based on a badge system, which was originally developed to remotely query individuals identify an animal herd to be monitored. A further development of this badge system is in the European Railways for accompanying monitoring of freight wagons and freight containers used.

Die ursprünglichen Plaketten, mit denen die Tiere in irgendeiner bekannten Weise markiert wurden, waren so aufgebaut, daß sie beim Empfang von mit einer bestimmten Frequenz ausgestrahlter HF-Energie die empfangene Energie nutzen, um auf derselben Frequenz ein mit der Nummer der Plakette und somit der Nummer des markierten Tiers moduliertes Signal zurückzusenden. Abfragestationen konnten an Tränken, Wildwechseln oder Eingängen zu Pferchen angebracht sein. Sie mußten einen HF-Dauerstrich-Sender und einen HF-Empfänger mit Demodulator aufweisen, womit die Plaketten abgefragt und deren Nummern ausgewertet werden konnten.The original plaques that the animals used in any known way were designed so that they when receiving broadcast at a certain frequency RF energy can use the received energy to work on the same Frequency in with the number of the badge and thus the number the modulated signal of the marked animal. polling stations could at drinking troughs, game changes or entrances Pens attached. They had to have an RF continuous wave transmitter and have an RF receiver with a demodulator, with which the badges are queried and their numbers are evaluated could.

Weiterentwicklungen der Plaketten gehen in verschiedene Richtungen. Durch in den Plaketten enthaltene Batterien kann die Reichweite für eine sichere Abfrage erhöht werden oder es können Zusatzfunktionen verwirklicht werden. Der Empfang von HF-Energie ist dann nur noch Auslöser für die Abfrage. Andere Weiterentwicklungen gehen dahin, auch Daten in den Plaketten von der Abfragestation aus zu ändern oder andere Daten abzufragen. Die Abfragestationen selbst sind entsprechend weiterentwickelt. Die Grundversion und einige Weiterentwicklungen sind beispielsweise beschrieben in den US-Patenten 4,739,328, 4,864,158, 5,030,807 und 5,055,659. Die bei den europäischen Eisenbahnen verwendeten Plaketten haben etwa das Format einer Scheckkarte und sind einige Millimeter dick.Further developments of the badges go in different directions. The batteries contained in the badge can Range can be increased for a safe query or it can Additional functions can be realized. The reception of RF energy is then only the trigger for the query. Other developments go there, too, dates in the plaques of change the query station or query other data. The query stations themselves have been further developed accordingly. The basic version and some further developments are for example described in U.S. Patents 4,739,328, 4,864,158, 5,030,807 and 5,055,659. The European railways The badges used are roughly the size of a credit card and are a few millimeters thick.

Solche Plaketten werden unter anderem auch verwendet, um Straßenbenutzungsgebühren im Vorbeifahren an einer elektronischen Mautstelle oder Parkgebühren bei der Einfahrt in einen Parkplatz zu entrichten. Umgekehrt kann die Position solcher Zahlstellen fahrzeugseitig ausgewertet werden, beispielsweise in Zusammenarbeit mit einem bordseitigen Navigationshilfsmittel.Such badges are also used, among other things Road user fees while driving past an electronic Toll gate or parking fees when entering one Pay parking space. Conversely, the position of such Paying agencies are evaluated on the vehicle side, for example in collaboration with an on-board navigation aid.

Es sind auch technisch andersartige Systeme aus solchen Abfragestationen und Antwortstationen denkbar und wohl auch bekannt, die dafür bestimmt und in der Lage sind, im Vorbeifahren in einem räumlich eng begrenzten Bereich durch einen vorherbestimmten Abfragezyklus, der selbstverständlich in jedem Fall anders aussieht, Information auzutauschen. There are also technically different systems from such interrogation stations and answering stations conceivable and well known, that are intended and able to drive past in a spatially narrow area by a predetermined one Query cycle that goes without saying in any case looks different, exchange information.

Der Erfindung liegt die Aufgabe zugrunde, unter Ausnützung vorhandener gattungsgemäßer Strukturen eine Grundlage zu weiteren Anwendungen zu schaffen.The invention has for its object, by using existing generic structures a basis for further To create applications.

Diese Aufgabe wird erfindungsgemäß gelöst durch ein Verfahren nach der Lehre des Anspruchs 1, eine Antwortstation nach der Lehre des Anspruchs 2 und eine Abfragestation nach der Lehre des Anspruchs 3.According to the invention, this object is achieved by a method according to the teaching of claim 1, a response station according to the Teaching of claim 2 and an interrogation station after the teaching of claim 3.

Erfindungsgemäß wird demnach die Möglichkeit eröffnet, auf eine andere Betriebsart umzuschalten, in der dann nicht nur ein einzelner Abfragezyklus erfolgt, sondern mittels aufeinanderfolgender Abfragezyklen beliebige Information durch transparente Datenübertragung austauschbar ist.According to the invention, the possibility is opened on to switch another operating mode, in which then not only one individual query cycle takes place, but by means of consecutive Query cycles any information through transparent Data transfer is interchangeable.

Die transparente Datenübertragung nach Art aufeinanderfolgender Abfragezyhlen ist aus der EP-A-0 495 600 an sich bekannt.The transparent data transmission in the manner of successive Query cycles are known per se from EP-A-0 495 600.

Die andere Betriebsart setzt natürlich voraus, daß während dieser gesamten Datenübertragung die Voraussetzungen für die Durchführung einer Vielzahl aufeinanderfolgender solcher Abfragezyklen in einem räumlich eng begrenzten Bereich gegeben sind. Beispiele hierfür sind aber genügend denkbar, insbesondere, wenn auf diese Weise auch Sprache übertragen werden soll. Üblicherweise liegen die bei solchen Abfragesystemen verwendeten Frequenzen derart hoch, daß selbst bei Vorbeifahrt mit sehr hoher Geschwindigkeit schon ein hoher Datendurchsatz erreichbar ist.The other operating mode assumes that during this entire data transfer the prerequisites for Carrying out a large number of successive such query cycles are given in a spatially narrow area. Sufficient examples of this are conceivable, in particular, if language is to be transmitted in this way. Usually are those used in such query systems Frequencies so high that even when driving past with very high High data throughput can be reached at speed is.

An den bereits genannten Einfahrten zu Parkplätzen beispielsweise kommt ein Fahrzeug in der Regel zunächst an einer Schranke zum Stehen. Hier sind dann bereits die Voraussetzungen für die Durchführung einer Vielzahl aufeinanderfolgender solcher Abfragezyklen in einem räumlich eng begrenzten Bereich gegeben. Hier ergibt sich aber auch gelegentlich die Forderung, mit einer Aufsichtskraft Sprechkontakt aufzunehmen. Erfindungsgemäß könnte dies dann über das hier vorausgesetzte System aus Abfragestation und Antwortstation erfolgen. Gegenüber bekannten Lösungen mit Sprechtaste, Mikrofon und Lautsprecher hätte diese Lösung auch noch den Vorteil, leichter gegen Witterung und Vandalismus geschützt werden zu können.For example, at the aforementioned entrances to parking lots a vehicle usually first comes to a barrier to stand. Here are the prerequisites for performing a variety of successive ones Query cycles given in a spatially narrow area. Here, however, there is also the occasional requirement, with a Supervisor to make voice contact. According to the invention this could then be done using the interrogation station system required here and answering station. Compared to known solutions with talk button, microphone and loudspeaker this would have been Solution also the advantage, easier against weather and vandalism to be protected.

In ähnlicher Weise könnte man Abfragestationen außer zu ihrer eigentlichen Zweckbestimmung auch noch als Notfallmelder verwenden.Similarly, one could use interrogators other than theirs Use the actual purpose as an emergency alarm.

Abfragestationen sind nicht nur stationär, sondern auch beispielsweise zur Überwachung nachfolgender Kraftfahrzeuge durch voraus- oder vorbeifahrende Polizeifahrzeuge vorgesehen. Auf erfindungsgemäße Weise ließen sich dann direkte Anweisungen oder Hinweise an einzelne Verkehrsteilnehmer durchgeben.Interrogation stations are not only stationary, but also for example to monitor subsequent motor vehicles police vehicles passing or passing provided. On Direct instructions could then be made in accordance with the invention or pass on information to individual road users.

Auch ließen sich beispielsweise elektronische Warenbegleitdokumente während des Lade- und Entladevorgangs an einer Laderampe oder im Zusammenhang mit einer Zollabfertigung schnell austauschen.Electronic goods accompanying documents can also be used, for example during the loading and unloading process on a loading ramp or exchange quickly in connection with customs clearance.

Weitere Ausgestaltungen der Erfindung sind den Unteransprüchen und der nachfolgenden Beschreibung zu entnehmen.Further embodiments of the invention are the subclaims and the following description.

Im folgenden wird die Erfindung unter Zuhilfenahme der beiliegenden Zeichnungen weiter erläutert:

Figur 1
zeigt eine erfindungsgemäße Abfragestation, in deren Bereich sich gerade ein Kraftfahrzeug mit einer erfindungsgemäßen Antwortstation befindet, bei der Durchführung eines erfindungsgemäßen Verfahrens.
Figur 2
zeigt den Ablauf eines erfindungsgemäßen Verfahrens.
The invention is further explained below with the aid of the accompanying drawings:
Figure 1
shows an interrogation station according to the invention, in the area of which there is a motor vehicle with an answering station according to the invention, when carrying out a method according to the invention.
Figure 2
shows the sequence of a method according to the invention.

Anhand der Figur 1 wird zunächst die Situation beschrieben, in der sich beispielhaft das erfindungsgemäße Verfahren abspielt. Ein Kraftfahrzeug 1, hier ein LKW, fährt auf eine Abfragestation 2 zu, bleibt kurz vor dieser stehen und nimmt eine Funkverbindung 3 mit dieser auf. Es wird hier unterstellt, daß sich jeweils nur ein Kraftfahrzeug in dem Bereich aufhalten kann, in dem eine Funkverbindung mit der Abfragestation möglich ist.The situation is first described using FIG. 1, in which the method according to the invention takes place as an example. A motor vehicle 1, here a truck, drives to an interrogation station 2 to, stops shortly before this and takes one Radio connection 3 with this. It is assumed here that there is only one motor vehicle in the area at a time can, in which a radio connection with the interrogation station is possible is.

Das Kraftfahrzeug 1 ist mit einer hier zweigeteilten Antwortstation 11, 12 ausgerüstet. Hinter der Windschutzscheibe befestigt ist eine Plakette 11, wie sie einleitend beschrieben ist und die alle Funktionen auszuführen in der Lage ist, die mit der Kontaktaufnahme zu einer Abfragestation und mit der Identifizierung einer solchen gegenüber erforderlich sind. Weiter ist ein Bordgerät 12 vorhanden, mittels dessen zusammen mit der Plakette 11 weitere Funktionen, insbesondere die erfindungsgemäßen Funktionen, durchgeführt werden können.The motor vehicle 1 has a two-part answering station 11, 12 equipped. Attached behind the windshield is a badge 11, as described in the introduction and that is able to perform all the functions that with contacting an interrogation station and with identification against such are required. Is further an on-board device 12 available, by means of which together with the Badge 11 further functions, in particular those according to the invention Functions that can be performed.

Die Abfragestation 2 ist hier ebenfalls geteilt. Auf einem Mast 21 befindet sich ein Sende- und Empfangsteil 22 mit einer Antenne 23. Am Mastfuß ist eine Auswerteeinheit 24 angebracht, die zusammen mit dem Sende- und Empfangsteil 22 die erfindungsgemäßen Funktionen durchführt und dazu mit diesem über ein Kabel 25 verbunden ist. Die Auswerteeinheit 24 ist weiter mit einem Kabel 26 an ein nicht weiter dargestelltes Kommunikationsund Datenverarbeitungssystem angeschlossen.The interrogation station 2 is also divided here. On one Mast 21 is a transmitting and receiving part 22 with a Antenna 23. An evaluation unit 24 is attached to the mast base, which together with the transmitting and receiving part 22, the invention Performs functions and for this with a cable 25 is connected. The evaluation unit 24 is also a Cable 26 to a communication and not shown Data processing system connected.

Die Funkverbindung 3 findet auf einer Frequenz und mit einem Leistungspegel statt, der der Kommunikation in einem räumlich eng begrenzten Bereich angepaßt ist. Anstelle einer Funkverbindung kann auch beispielsweise eine Infrarotverbindung oder eine induktive Kopplung treten.The radio link 3 takes place on one frequency and with one Power level instead of that of communication in a spatial narrow range is adapted. Instead of a radio link can also, for example, an infrared connection or inductive coupling occur.

Bis auf einzelne Funktionen unterscheidet sich die Erfindung nicht von den bereits oben ausführlich dargestellten Systemen und braucht deshalb insoweit nicht weiter erläutert zu werden. The invention differs except for individual functions not from the systems already detailed above and therefore need not be explained further.

An Hand der Figur 2 wird nun der Ablauf des erfindungsgemäßen Verfahrens dargestellt. Die an den Geräten hierfür erforderlichen Abwandlungen und Ergänzungen werden dabei von selbst verständlich.The sequence of the invention will now be described with reference to FIG Procedure illustrated. The equipment required for this Modifications and additions are self-evident.

Ausgangspunkt sind normale Abfragezyklen, wie sie laufend von der Abfragestation 2 zumindest versucht werden. Der gesamte Dateninhalt, der zwischen dem Kraftfahrzeug 1 und der Abfragestation 2 über die Funkverbindung 3 ausgetauscht wird, ist in Figur 2 mit 4 gekennzeichnet. Die Abfragestation 2 sendet in diesem Beispiel laufend Bakensignale 41, durch die in den Bereich der Abfragestation 2 kommende Kraftfahrzeuge einerseits verschiedene Daten, wie die Position, erhalten und andererseits aufgefordert werden, eine bestimmte Gebühr zu bezahlen oder deren bereits erfolgte Bezahlung nachzuweisen.The starting point are normal query cycles, such as those running from the query station 2 are at least tried. The entire data content, between the motor vehicle 1 and the interrogation station 2 is exchanged via the radio link 3, is in Figure 2 marked with 4. The interrogation station 2 transmits in this Example ongoing beacon signals 41 through which in the area the interrogation station 2 coming motor vehicles on the one hand different Data such as the position received and on the other hand be asked to pay a certain fee or their proof of payment already made.

Empfängt nun das Kraftfahrzeug 1 ein solches Bakensignal 41, so antwortet es mit einem Antwortsignal 42. Der Abfragezyklus wird abgeschlossen durch ein Bestätigungssignal 43 der Abfragestation 2 und ein Bestätigungssignal 44 der Antwortstation im Kraftfahrzeug 1. Der hier dargestellte Ablauf eines Abfragezyklus ist nur beispielhaft gewählt. Selbstverständlich kann ein beliebiger vorab bestimmter und zur Durchführung während einer kurzen Vorbeifahrt geeigneter Ablauf gewählt werden.If the motor vehicle 1 now receives such a beacon signal 41, so it answers with a response signal 42. The polling cycle is completed by an acknowledgment signal 43 from the interrogation station 2 and a confirmation signal 44 of the answering station in Motor vehicle 1. The sequence of a query cycle shown here is chosen only as an example. Of course, one can any predetermined and to be performed during a suitable passage can be chosen.

Wird nun in der Abfragestation 2 festgestellt, daß eine erfindungsgemäße transparente Datenübertragung erfolgen soll, so wird auf eine andere Betriebsart umgeschaltet. Die Feststellung selbst kann durch Auswerten des Antwortsignals 42 oder durch Auswerten von Daten erfolgen, die in der Abfragestation 2 vorliegen. Natürlich macht es nur einen Sinn, auf transparente Datenübertragung umzuschalten, wenn anzunehmen ist, daß ausreichend lange eine Verbindung möglich sein wird. Dies muß aber nicht zwingend auch vorab technisch abgeprüft werden. It is now found in the interrogation station 2 that an inventive transparent data transmission should take place, so is switched to another operating mode. The finding itself can by evaluating the response signal 42 or by Data that is available in the interrogation station 2 are evaluated. Of course, it only makes sense to have transparent data transmission to switch if it is assumed that sufficient long connection will be possible. But this must not necessarily be technically checked in advance.

Der nächste Abfragezyklus beginnt nun wieder mit einem Bakensignal 41 und wird von der Antwortstation des Kraftfahrzeugs 1 mit einem Informationssignal 45 beantwortet, worauf die Abfragestation ein Informationssignal 46 sendet. Abgeschlossen wird der Abfragezyklus wieder durch ein Bestätigungssignal 44 von Seiten des Kraftfahrzeugs. Das Informationssignal 45 beinhaltet einen Datenteil 51 einer vom Kraftfahrzeug 1 zu übertragenden Information 5; das Informationssignal 46 beinhaltet einen Datenteil 61 einer von der Abfragestation 2 zum Kraftfahrzeug 1 zu übertragenden Information 6.The next polling cycle now starts again with a beacon signal 41 and is from the answering station of the motor vehicle 1 answered with an information signal 45, whereupon the interrogation station sends an information signal 46. Is completed the polling cycle again by a confirmation signal 44 from Sides of the motor vehicle. The information signal 45 includes a data part 51 of a vehicle 1 to be transmitted Information 5; the information signal 46 contains a data part 61 one from the interrogation station 2 to the motor vehicle 1 Information to be transmitted 6.

Die Abfragezyklen zum Austausch von Information durch transparente Datenübertragung sind hier grundsätzlich gleich ausgestaltet wie die Abfragezyklen zur Durchführung einer einmaligen Meldeaktion. Damit können die Mechanismen mitbenutzt werden, die beispielsweise zur Sicherung der Datenintegrität bereits getroffen wurden. Auch die regelmäßige Überprüfung, ob überhaupt noch Verbindung besteht, erfolgt damit automatisch. Am Ende geht die Abfragestation wieder dazu über, Bakensignale 41 zu senden.The query cycles for the exchange of information through transparent Data transmission is basically the same here like the polling cycles to perform a one time Reporting action. So the mechanisms can be shared which, for example, already ensures data integrity were hit. Also the regular check, if at all connection is established automatically. At the In the end, the interrogation station goes back to beacon signals 41 to send.

Die Abfragezyklen selbst können grundsätzlich auch anders aussehen. Jedenfalls wird davon ausgegangen, daß zu anderen Zwecken bereits in sich abgeschlossene Abfragezyklen definiert sind, durch die verschiedene Grundfunktionen schon erfüllt sind. Diese Abfragezyklen werden nun verwendet, um einen kontinuierlichen Datenfluß, Sprachdaten eingeschlossen, zu ermöglichen.In principle, the query cycles themselves can also be different appearance. In any case, it is assumed that to others Purpose defined self-contained query cycles through which various basic functions are already fulfilled are. These polling cycles are now used to create a continuous To enable data flow, including voice data.
