Description

Die Erfindung betrifft ein Verfahren und eine Einrichtung zur Warnung von Personen im Gleisbereich mit den im Oberbegriff der Patentansprüche 1 bzw. 9 angegebenen Merkmalen.The invention relates to a method and a device for warning people in the track area with the features specified in the preamble of claims 1 and 9, respectively.

Bekannt sind Einrichtungen zur Warnung von Personen im Gleisbereich vor herannahenden Zügen durch eine hochfrequente, zyklisch zeitmultiplexe Nachrichtenübermittlung je eines Warnsenders an durch Adressierung zugeordnete Warnempfänger, die von allen im Gefahrenbereich tätigen Arbeitskräften getragen werden (LENGEMANN, STEIN, "Die Individualwarnanlage IWA" in Eisenbahningenieur, 1987, H.2, S.51-56 bzw. LENGEMANN, DOHRS, FRANK, "Automatische Rottenwarnsysteme - von der kollektiven zur individuellen Warnanlage" in Signal + Draht, 1987, H.1/2, S.31-38). Zur Koordinierung des Multiplexverfahrens wertet der Warnsender die Sendeimpulse möglicher anderer Warnsender aus, soweit sich die Sendeimpulse aufgrund ihrer Feldstärke auswerten lassen, sodaß sich der topographische Raum der Koordinierung durch die Feldstärkeverhältnisse ergibt; es wird aber kein Feldstärkemesser eingesetzt und keine Feldstärkemessung durchgeführt. Die Warnsender und Warnempfänger enthalten Prozessoren, die Warnempfänger einen HF-Empfangsteil mit Demodulator und Antenne, die Warnsender darüberhinaus einen HF-Sendeteil mit Modulator; sie sind nicht angenähert baugleich.Devices are known for warning people in the track area of approaching trains by means of a high-frequency, cyclically time-multiplexed message transmission of one warning transmitter each to addressees assigned by addressing, which are carried by all workers working in the danger area (LENGEMANN, STEIN, "The individual warning system IWA" in railway engineers, 1987, H.2, p.51-56 or LENGEMANN, DOHRS, FRANK, "Automatic Rottenwarnsysteme - from the collective to the individual warning system" in Signal + Draht, 1987, H.1 / 2, p.31-38). To coordinate the multiplex method, the warning transmitter evaluates the transmission impulses of other possible warning transmitters, insofar as the transmission impulses can be evaluated on the basis of their field strength, so that the topographical area of coordination results from the field strength relationships; however, no field strength meter is used and no field strength measurement is carried out. The warning transmitters and warning receivers contain processors, the warning receivers an HF receiving part with demodulator and antenna, the warning transmitters furthermore an HF transmitting part with modulator; they are not nearly identical.

Bekannt sind auch Einrichtungen zur Warnung von Personen im Gleisbereich über einen hochfrequenten Nachrichtenkanal durch die Veröffentlichungen ANGRABEIT, "Automatisierung der Rottenwarnung" in Signal + Draht, 1981, H.1/2, S.51-63 und LENGEMANN, "Von der Erkennung bis zur Alarmgebung" in Elektrische Bahnen, 1983, H.6, S.204-209. Zum Betrieb mehrerer solcher Einrichtungen in der Nähe zueinander sind jedoch mehrere hochfrequente Nachrichtenkanäle notwendig, um gegenseitiges Zustopfen der Stationen zu vermeiden. In Anbetracht des hohen Bedarfs an Warnanlagen und der geringen Anzahl zur Verfügung stehender Hochfrequenzkanäle sind ohne weitere Maßnahmen die beschriebenen Einrichtungen praktisch nicht anwendbar und wurden bis auf einzelne Versuche auch noch nicht eingesetzt. Asynchrone Hochfrequenzmultiplexverfahren sind wegen der zu lange dauernden Kollisionsauflösung bei Überdeckungen der Sendezeiten nicht anwendbar. Weiterhin sind Zeitmultiplexverfahren für die Nachrichtenübermittlung über einen hochfrequenten Kanal bekannt (DE-AS 2818916 und DE-PS 3603907), die jedoch nur das Zustopfen einzelner Stationen verhindern, die ihre Nachrichten zu ihnen unmittelbar zugeordnete Empfänger absetzen. Ein Verhindern von Zustopfen bei der Nachrichtenübermittlung zwischen den Stationen ist mit diesen Verfahren nicht möglich, insbesondere nicht bei verketteten, nachrichtenübermittelnden Stationen und deren eventuell benachbarten Warnanlagen, wie dies typisch ist für Anlagen zur Warnung von Personen im Gleisbereich. Aufgabe der Erfindung ist es daher, ein Verfahren und eine Einrichtung anzugeben, bei welchen es möglich wird, Personen im Gleisbereich vor herannahenden Zügen durch am Gleis aufgestellte, Züge detektierende Meldestationen, die den Zug signalisierende Statusinformationen an eine im Arbeitsbereich der Personen befindliche, zur Alarmgebung fähige Warnstation über einen hochfrequenten Nachrichtenkanal im Zeitmultiplexbetrieb mit gleicher Sendeperiode leiten, zu warnen, wobei ein Zustopfen der Stationen verhindert wird, auch dann, wenn Anlagen dieser Art benachbart sind.Also known are devices for warning people in the track area via a high-frequency news channel through the publications ANGRABEIT, "Automation of the Rottenwarnung" in Signal + Draht, 1981, H.1 / 2, p.51-63 and LENGEMANN, "From detection to for alarming "in electric railways, 1983, H.6, p.204-209. In order to operate several such devices in the vicinity of one another, however, several high-frequency message channels are necessary in order to avoid mutual plugging of the stations. In view of the high demand for warning systems and the small number of available high-frequency channels, the described devices are practically not applicable without further measures and have not yet been used except for individual tests. Asynchronous high-frequency multiplexing methods cannot be used due to the collision resolution, which takes too long, if the transmission times overlap. Furthermore, time-division multiplexing methods for the transmission of messages via a high-frequency channel are known (DE-AS 2818916 and DE-PS 3603907), which, however, only prevent the plugging of individual stations which send their messages to recipients directly assigned to them. Preventing blockages in the transmission of messages between the stations is not possible with these methods, in particular not in the case of chained, message-transmitting stations and their possibly adjacent warning systems, as is typical for systems for warning people in the track area. The object of the invention is therefore to provide a method and a device in which it is possible to alert people in the track area in front of approaching trains by train stations set up on the track, which detect trains and signal the status information to a person in the work area to warn capable warning station over a high-frequency message channel in time-division multiplex operation with the same transmission period, preventing clogging of the stations, even if systems of this type are adjacent.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale 5 des Anspruchs 1 bzw. 9 gelöst.This object is achieved by the characterizing features 5 of claim 1 and 9 respectively.

Das Verfahren bzw. die Einrichtung gemäß der Erfindung hat den besonderen Vorteil, daß erstmals der Betrieb mehrerer Anlagen zur Warnung von Personen im Gleisbereich vor herannahenden Zügen auf einem einzigen hochfrequenten Kanal möglich wird. Neben einer nicht weiter verbesserbaren Frequenz-Ökonomie wird eine Einsatzplanung von unterschiedlichen Hochfrequenzkanälen überflüssig und eine baugleiche Ausbildung von Warn- und Meldestationen möglich, die eine wirtschaftliche Herstellung als auch eine ökonomische Vorhaltung beim Betreiber ermöglicht.The method and the device according to the invention has the particular advantage that for the first time the operation of several systems for warning people in the track area against approaching trains on one single high-frequency channel is possible. In addition to a frequency economy that cannot be further improved, there is no need to plan the use of different high-frequency channels, and identical construction of warning and signaling stations is possible, which enables economical production as well as economical provision by the operator.

Nachfolgend sind vorteilhafte Weiterbildungen der Erfindung erwähnt.Advantageous developments of the invention are mentioned below.

Die Merkmale des Anspruchs 2 bzw. 10 ermöglichen die Reduzierung der Anzahl der Zeitschlitze pro Sendeperiode durch Vermeidung der Belegungserfassung rückgemeldeter eigener Sendezeitschlitze der Stationen.The features of claims 2 and 10 enable the number of time slots per transmission period to be reduced by avoiding the occupancy detection of the own transmission time slots of the stations that have been reported.

Einer sicherheitstechnischen Ansprüchen genügenden Einschaltprozedur dienen die Merkmale des Anspruchs 3 bzw. 11. Damit sind auch während des Betriebs defekte Stationen abschaltbar und neue Stationen zuschaltbar, um die Verfügbarkeit zu erhöhen.The features of claims 3 and 11 serve to meet a safety-related power-up procedure. Defective stations can thus be switched off and new stations switched on during operation in order to increase the availability.

Bei dem Einsatz von Warnanlagen bei wandernden Baustellen ergeben die Merkmale des Anspruchs 4 bzw. 12 eine Aktualisierung der Zeitschlitze, sodaß auch die Sendeverhältnisse der übrigen Stationen am vorher belegten Zeitschlitz erfaßt werden können. Ermöglicht wird dies durch die Besonderheit des Verfahrens einer freien Wahl eines Zeitschlitzes aus allen als nicht belegt erfaßten und gemeldeten Zeitschlitzen. Die Merkmale des Anspruchs 5 bzw. 13 ermöglichen eine zweckmäßige Aufstellungsart bei Baugleichheit aller Meldestationen und eine eventuelle Einsparung an belegten Zeitschlitzen bei Leitungsanschluß der Warnstation mit ihren Nachbarn.When warning systems are used on moving construction sites, the features of claims 4 and 12 result in an update of the time slots, so that the transmission conditions of the other stations at the previously occupied time slot can also be recorded. This is made possible by the peculiarity of the method of freely selecting a time slot from all time slots recorded and reported as not being occupied. The features of claims 5 and 13 enable an expedient type of installation with identical construction of all reporting stations and possible savings in occupied time slots when the warning station is connected to its neighbors.

Die Merkmale des Anspruchs 6 bzw. 14 haben eine wesentliche Bedeutung. Sie lösen unter Wahrung der Baugleichheit der Stationen Reichweitenprobleme bei schwierigen Geländeverhältnissen, ohne daß dadurch die sicherheitstechnische Abgrenzung einer maximalen Verzugszeit der Nachrichten gefährdet wird.The features of claims 6 and 14 have an essential meaning. While maintaining the identical construction of the stations, they solve range problems in difficult terrain conditions, without endangering the security delimitation of a maximum delay time of the messages.

Ebenso kommt den Ansprüchen 7 und 8 bzw. 15 und 16 eine wesentliche Bedeutung zu. Der Auswahl der zweckmäßigsten Meldestationen bei deren Umsetzen oder vorheriger Aufstellung in Wanderrichtung der Baustelle dienen die Merkmale des Anspruchs 7 bzw. 15. Eine diesbezüglich automatische Auswahl der Meldestationen bei sicherheitstechnischer Überwachung dienen die Merkmale des Anspruchs 8 bzw. 16.Claims 7 and 8 and 15 and 16 are also of significant importance. The features of claims 7 and 15 serve to select the most appropriate reporting stations when they are implemented or previously set up in the direction of travel of the construction site. The features of claims 8 and 16 are used to automatically select the reporting stations with security monitoring.

Die Merkmale des Anspruchs 17 ermöglichen durch an sich bekannte Maßnahmen (Elektrotechnik und Informationstechnik, 1988, H.11, S.491) in einer wirtschaftlichen und gut prüfbaren Weise die sicherheitstechnisch notwendige Offenbarung eines Fehlers in der Einrichtung.The features of claim 17 enable known per se Measures (electrical engineering and information technology, 1988, H.11, p.491) in an economical and easily verifiable manner the safety-related disclosure of an error in the facility.

  • F 1 G. 5 is another block diagram of a station

In F I G. 1 ist die typische linienförmige Anordnung der Stationen (1 bis 9) an einer Bahnstrecke skizziert. Ein sich von links nähernder Zug wird durch eine Meldestation 1 (mit Hilfe eines den Zug und dessen Richtung erkennenden Sensors) detektiert, einer Warnstation 5 im Arbeitsbereich der Personen gemeldet und bei Passieren einer Meldestation 7 wieder abgemeldet. In umgekehrter Zugfahrtrichtung kündigt eine Meldestation 9 den Zug der Warnstation 5 an und eine Meldestation 3 meldet den aus dem Arbeitsbereich fahrenden Zug. Die für eine rechtzeitige Warnung erforderliche Entfernung der ankündigenden Stationen (1, 9) zur Warnstation (5) beträgt etwa 3 km, wohingegen die abmeldenden Stationen (3, 7) in der Nähe der Warnstation (5) aufgestellt sind. Eine Meldestation 31 einer benachbarten Warnanlage ist angedeutet. Die sich ergebenden typischen Feldstärkeverhältnisse und die sich daher im gegenseitigen Einflußbereich befindlichen Stationen sind durch die sie umschließenden Felder 21 bis 25 beispielhaft dargestellt.F I G. 1 outlines the typical linear arrangement of the stations (1 to 9) on a railway line. A train approaching from the left is detected by a reporting station 1 (with the aid of a sensor which detects the train and its direction), reported to a warning station 5 in the work area of the people and, when passing through a reporting station 7, is logged off again. In the opposite direction of train travel, a reporting station 9 announces the train of the warning station 5 and a reporting station 3 reports the train leaving the work area. The distance from the announcing stations (1, 9) to the warning station (5) required for a timely warning is approximately 3 km, whereas the deregistering stations (3, 7) are set up near the warning station (5). A reporting station 31 of an adjacent warning system is indicated. The resulting typical field strength ratios and the stations that are therefore in the mutual sphere of influence are exemplified by the fields 21 to 25 surrounding them.

In F I G. 4 ist ein Beispiel einer Station (1 bis 9, 31) dargestellt, deren Schaltungsaufbau eine gleiche Bauart der Stationen ermöglicht. Ein mit einem Taktgenerator 57 verbundener Prozessor 55 empfängt und gibt Informationen über einen Sende-/Empfangsteil 51 und dessen Antenne 53 ab. Die Nachrichtenverbindung zu den anderen Stationen ist ein hochfrequenter Kanal im Zeitmultiplexbetrieb mit gleicher Sendeperiode der Stationen. Der Prozessor 55 ist mit einem im wesentlichen das Programm enthaltenen Festwertspeicher 59 und einem Speicher 61 verbunden. Er führt Arbeitsschritte durch, die direkt den Ansprüchen entnommen werden können. Er kann Warnmittel 63 in einer Warnstation (5) anreizen und Züge und deren Richtung durch einen Sensor 65 in Meldestationen (1, 3, 7, 9) detektieren. Eine einstellbare Adresse 67 zur Adressierung der Stationen (1 bis 9, 31) wird dem Prozessor ebenfalls zugeführt. Falls sich Meldestationen (3, 7) in unmittelbarer Nähe der Warnstation (5) befinden, können diese ihre Informationen über sie verbindende Leitungen 69 anstatt über den Hochfrequenzkanal austauschen zur Reduzierung sonst erforderlicher Sendezeitschlitze. Durch Verdopplung der Schaltungsblöcke 75, 77 (Fig.4) gemäß F I G. 5 können sicherheitstechnische Erfordernisse zur Aufdeckung eines Fehlers erfüllt werden, indem die Prozessoren 55 über eine Verbindungsleitung Quittungssignale zur Koordinierung ihres angenäherten Gleichlaufs austauschen. Bei zu großen Abweichungen des Gleichlaufs lösen die Prozessoren 55 Alarm aus.FI G. 4 shows an example of a station (1 to 9, 31), the circuit structure of which enables the stations to be of the same type. A processor 55 connected to a clock generator 57 receives and outputs information about a transceiver 51 and its antenna 53. The communication link to the other stations is a high-frequency channel in time division multiplex operation with the same transmission period of the stations. The processor 55 is connected to a read-only memory 59 which essentially contains the program and a memory 61. He carries out work steps that can be taken directly from the claims. He can stimulate warning means 63 in a warning station (5) and detect trains and their direction by a sensor 65 in reporting stations (1, 3, 7, 9). An adjustable address 67 the processor is also fed to address the stations (1 to 9, 31). If signaling stations (3, 7) are in the immediate vicinity of the warning station (5), they can exchange their information via lines 69 connecting them instead of via the high-frequency channel to reduce the otherwise required transmission time slots. By doubling the circuit blocks 75, 77 (FIG. 4) according to FI G. 5, safety requirements for detecting an error can be met by the processors 55 exchanging acknowledgment signals via a connecting line for coordinating their approximated synchronization. If the synchronization deviations are too great, the processors 55 trigger an alarm.

In F I G. 3 sind die Sende- und Empfangsverhältnisse in den Zeitschlitzen (Z) 1 bis 6 einer Sendeperiode bei den Stationen 1 bis 9 und 31 für das Beispiel nach Fig. 1 dargestellt. Für jede Station ist von unten nach oben zeilenförmig der eigene Sendezeitschlitz (S), die direkt aufgrund der Feldstärkeverhältnisse empfangenen anderen Stationen (E) und die indirekt empfangenen, von diesen Stationen (M) als belegt gemeldeten Zeitschlitze eingetragen. Es ist zunächst angenommen, daß nur de Station 31 der benachbarten Anlage im Zeitschlitz 2 sendet. Sie wird nur von der Station 1 direkt empfangen. Es wird weiter angenommen, daß die Stationen 1 bis 9 nun im Abstand einiger Perioden in dieser Reihenfolge in Betrieb gehen. Zunächst erkennt die Station 1 die Zeitschlitze 1 sowie 3 bis 6 als frei und wählt beispielsweise den Zeitschlitz 1 als künftigen eigenen Sendezeitschlitz aus. Im Zeitschlitz 1 sendet die Station 1 auch eine Information über den als belegt erkannten Zeitschlitz 2 als relative Lage zum eigenen Zeitschlitz 1, z.B. als Zeitschlitzinkrement +1, da der zu meldende Zeitschlitz 2 ein Zeitschlitzinkrement später folgt. Eine gleichzeitige Meldung der Adresse der so empfangenen Station 31 ist vorteilhaft für eine Rückmeldung zu dieser zur Identifikation der Meldung des eigenen Zeitschlitzes. Die Nachricht erreicht entsprechend den Feldstärkeverhältnissen 23 die Stationen 3 bis 7 im Zeitschlitz 1, die daraufhin den Zeitschlitz 1 wegen des direkten Empfangs (E) und durch Addition der Meldung +1 den Zeitschlitz 2 indirekt als belegt (M) für mehrere Perioden überschreibend speichern, letzteres, um einerseits Einflüssen von Feldstärkeschwankungen zu begegnen und diese Nachricht auf mehrere Perioden verteilen zu können und um andererseits eine Aktualisierung nicht zu verhindern. Die letzte in Betrieb gehende Station 9 speichert wegen der Feldstärkeverhältnisse 25 die Zeitschlitze 3 bis 5 direkt (E) und den Zeitschlitz 1 indirekt (M) durch Belegtmeldung der Stationen 3 bis 7 als besetzt. Die Station 9 kann den freien Zeitschlitz 6, aber auch den bereits durch die Station 31 benutzten Zeitschlitz 2 als eigenen Sendezeitschlitz auswählen. Hier wird der Vorteil der freien Auswahl der Zeitschlitze bei Erfassung der wirklichen, feldstärkeabhängigen Verkettungen der Station deutlich: unnötige Sendezeitschlitze werden vermieden, sodaß praktisch alle Warnanlagen auf einem hochfrequenten Kanal betrieben werden können, auch wenn sie mit Nachbaranlagen zusammenstoßen. Ein sporadischer Zeitschlitzwechsel, angereizt z.B durch einen Zufallallgorithmus im Prozessor 55, ermöglicht problemloses Umsetzen der Stationen bei wandernden Baustellen, da dann auch der vorher selbst belegte Zeitschlitz der Station geprüft wird.FI G. 3 shows the transmission and reception relationships in time slots (Z) 1 to 6 of a transmission period at stations 1 to 9 and 31 for the example according to FIG. 1. For each station, the own transmission time slot (S), the other stations (E) received directly due to the field strength ratios and the indirectly received time slots reported by these stations (M) as occupied are entered in rows from bottom to top. It is initially assumed that only station 31 of the neighboring system transmits in time slot 2. It is only received directly by station 1. It is further assumed that stations 1 to 9 now go into operation in this order at intervals of a few periods. First, station 1 recognizes time slots 1 and 3 to 6 as free and, for example, selects time slot 1 as its own future transmission time slot. In the time slot 1, the station 1 also sends information about the time slot 2 recognized as occupied as a position relative to its own time slot 1, for example as a time slot increment +1, since the time slot 2 to be reported follows a time slot increment later. A simultaneous notification of the address of the station 31 received in this way is advantageous for a response to this in order to identify the notification of the own time slot. The message reaches the stations 3 to 7 in the time slot 1 in accordance with the field strength ratios 23, which then save the time slot 1 indirectly as occupied (M) for several periods due to the direct reception (E) and by adding the message +1, the latter, in order on the one hand to counter influences of field strength fluctuations and to be able to distribute this message over several periods and on the other hand not to prevent an update. The last operating station 9 stores the time slots because of the field strength ratios 25 3 to 5 direct (E) and time slot 1 indirect (M) by busy signaling of stations 3 to 7 as occupied. The station 9 can select the free time slot 6, but also the time slot 2 already used by the station 31, as its own transmission time slot. The advantage of free selection of the time slots when recording the actual field strength-dependent linkages of the station becomes clear: unnecessary transmission time slots are avoided, so that practically all warning systems can be operated on a high-frequency channel, even if they collide with neighboring systems. A sporadic time slot change, stimulated, for example, by a random algorithm in the processor 55, enables problem-free implementation of the stations on moving construction sites, since the station's previously occupied time slot is also checked.

Der Prozessor 55 der Meldestation 5 kann durch entsprechende Informationen über den hochfrequenten Kanal die Prozessoren 55 der Meldestationen (1, 3, 7, 9) dazu anreizen, den Betrieb aufzunehmen oder einzustellen oder die Betriebsart zu wechseln, auch in Abhängigkeit einer Feldstärkemessung im Sende-/Empfangsteil 51, wobei dem Betrieb als Relaisstation bei schlechten Funkausbreitungen besondere Bedeutung zukommt. Eine solche Situation ist in F I G. 2 dargestellt. Eine Meldestation (11) übermittelt ihre Informationen über eine Relaisstation 9 an die Warnstation 5, indem der Prozessor 55 der Relaisstation 9 die empfangene Information im Speicher 61 zwischenspeichert und im nächsten eigenen Sendezeitschlitz zuzüglich einer die Zeit zwischen dem Empfangszeitschlitz und dem eigenen Sendezeitschlitz kennzeichnenden Information über den Verzug in der Relaisstation an die Warnstation 5 sendet, deren Prozessor 55 diese Verzugszeit von einer gespeicherten (59) maximal zulässigen Verzugszeit abzieht und zwischenspeichert (61) als die Zeit, bei deren Überschreitung infolge erfolglosem Empfang ab diesem Zeitpunkt Alarm (63) ausgelöst wird. Das Umsetzen der Stationen (1 bis 11) wird sicherheitstechnisch problemlos, wenn durch einstellbare Ortsadressen (67) der Prozessor 55 in der Warnstation 5 durch Vergleich mit den als Information empfangenen Ortsadressen anderer Stationen deren Entfernung und Richtung ermitteln kann und so mit im Speicher 59 vorgegebenen Mindestabstand zu ankündigenden Meldestationen (1, 11) prüfen kann. Der Prozessor 55 der Warnstation 5 kann in äquivalenter Weise bei umgesetzten Stationen deren neue Entfernung prüfen und die Betriebsarten entsprechend automatisch wählen. So kann z.B. bei Umsetzen der Warnstation 5 in die Position 5a die Relaisstation 9 in eine abmeldende Station aufgrund der neuen Verhältnisse durch die Warnstation 5 umgeschaltet werden.The processor 55 of the signaling station 5 can stimulate the processors 55 of the signaling stations (1, 3, 7, 9) to start or stop operation or to change the operating mode, also as a function of a field strength measurement in the transmission, by corresponding information about the high-frequency channel. / Receiving part 51, the operation as a relay station being of particular importance in the case of poor radio propagation. Such a situation is shown in FI G. 2. A reporting station (11) transmits its information to the warning station 5 via a relay station 9, in that the processor 55 of the relay station 9 buffers the received information in the memory 61 and in the next own transmission time slot plus information identifying the time between the reception time slot and the own transmission time slot sends the delay in the relay station to the warning station 5, the processor 55 subtracts this delay time from a stored (59) maximum permissible delay time and temporarily stores (61) the time when it is exceeded as a result of which unsuccessful reception triggers the alarm (63) from this point in time . The implementation of the stations (1 to 11) becomes problem-free in terms of security if the processor 55 in the warning station 5 can determine their distance and direction by means of adjustable location addresses (67) by comparison with the location addresses received as information, and thus predetermined in the memory 59 Check minimum distance to announcing reporting stations (1, 11). The processor 55 of the warning station 5 can, in an equivalent manner, check the new distance of the converted stations and automatically select the operating modes accordingly. For example, when the warning station 5 is moved to position 5a, the relay station 9 can be moved to a deregistering station can be switched due to the new conditions by warning station 5.
