Description

Die Erfindung bezieht sich auf ein mobiles Datenterminal für ein Taxifahrzeug, mit einer Taxameterbaugruppe, die eine auf mehrere Tarifstufen umschaltbare Schaltvorrichtung aufweist zur Auswertung einer Tarifumschaltinformation und von Anweisungen aus einer ortsfesten Taxizentrale dergestalt, daß durch eine Funk-Übertragung einer Information der Taxameter in eine von der Taxizentrale vorgegebene Tarifstufe steuerbar ist.The invention relates to a mobile data terminal for a taxi vehicle, with a taximeter module, which has a switchable switch to multiple tariff levels for evaluating tariff switching information and instructions from a fixed taxi center in such a way that by radio transmission of information the taximeter into one of the taxi center is taxable at the specified tariff level.

Bekanntlich sind die Standorte von Taxifahrzeugen, soweit es die örtlichen Verhältnisse zulassen, entsprechend der auftretenden Kundenfrequenz und nach Gesichtspunkten einer optimalen Ausgangslage der Taxistellplätze über den Einzugsbereich einer Stadt verteilt angeordnet. Zur Verbesserung der Wirtschaftlichkeit und Optimierung der Verteilung der anfallenden Fahrteneinsätze verfügen die einzelnen Taxiunternehmen bereits über ein zentrales Funkrufsystem. Entsprechend steht jedes Taxifahrzeug im Funk-Wechselsprechverkehr mit einer Zentrale in dauernder Verbindung, insbesondere mit dem Ziele der besseren Koordinierung und Verteilung der zentral eingehenden Aufträge an die einzelnen Taxifahrzeuge. Zu diesem Zweck sind in jedem einer Zentrale angeschlossenen Taxifahrzeug eine Sende- und Empfangsanlage eingebaut, über welche durch verbale Übermittlung der Einsatz der Fahrzeuge gesteuert wird.As is well known, the locations of taxi vehicles are, as far as the local conditions allow, distributed over the catchment area of a city according to the frequency of customers and according to the optimal starting position of the taxi parking spaces. The individual taxi companies already have a central radio paging system to improve cost-effectiveness and optimize the distribution of the incurred driving assignments. Accordingly, each taxi vehicle is in constant radio communication with a head office, in particular with the aim of better coordinating and distributing the centrally incoming orders to the individual taxi vehicles. For this purpose, a transmission and reception system is installed in each taxi vehicle connected to a control center, via which the use of the vehicles is controlled by verbal transmission.

Diese Art der Übermittlung der Fahraufträge ist jedoch nicht immer fehlerfrei abzuwickeln, weil durch sprachliche Übertragung Mißverständnisse aufgrund von Hörfehlern entstehen können. Auch ist es bei dichtem Verkehrsaufkommen nicht opportun, die Fahrer durch neue Auftragsübermittlungen vom Verkehrsgeschehen abzulenken. Schließlich bleibt ein Folgefahrauftrag auf diese Weise nicht erfüllt, unter Umständen sehr zum Schaden der beauftragten Taxiunternehmung. Es ist sicherlich ein allgemeines Bedürfnis für einen Taxifahrer, von derartigen Wechselgesprächen mit seiner Zentrale wegzukommen und die ganze Konzentration der Sicherheit seiner Fahrweise im Verkehrsgewühl zuzuwenden. Es ist jedoch nicht zu vermeiden, daß sich ein Fahrauftrag mit der Übermittlung bzw. Annahme neuer Fahraufträge überschneidet, dies ist insbesondere von wirtschaftlichem Vorteil, wenn durch eine ständige Ortung der Position eines Fahrzeuges große Anfahrtswege damit vermeidbar sind.However, this type of transmission of the driving orders is not always error-free, because misunderstandings can arise due to hearing errors due to speech transmission. Also, when traffic is heavy, it is not opportune to distract the driver from the traffic situation by sending new orders. After all, a follow-up driving order is not fulfilled in this way, possibly to the detriment of the taxi company commissioned. It is certainly a general need for a taxi driver to get away from such exchanges with their headquarters and to concentrate on the safety of driving in traffic. However, it cannot be avoided that a driving order overlaps with the transmission or acceptance of new driving orders. This is particularly advantageous if long journeys can be avoided by constantly locating the position of a vehicle.

Um eine Gleichstellung aller Fahrer in bezug auf die Einhaltung der zu gegebenem Zeitpunkt aktuellen Tarifstufe zu erreichen, ist aus der DE-AS 2 037 048 eine automatisch steuerbare Tarifumschaltvorrichtung bekannt geworden. Diese Einrichtung dient vor allem dem Zweck der Umschaltung auf sog. Sondertarife, wie beispielsweise Nacht-, Wochenend-, Feiertags-Tarif und dergl., ohne Möglichkeit der Einflußnahme seitens des Fahrers. Diese Einrichtung ist als Zusatzeinheit der bereits vorhandenen Funkwechselsprechanlage ausgebildet. Es werden für die Dauer des Gültigkeitsbereiches eines Sondertarifes in regelmäßigen Zeitintervallen von der Zentrale Tarifschaltsignale ausgestrahlt, die ein elektronisches Zeitrelais eines Zeitkreises in die Selbsthaltung steuern. Die der Relaisschaltung zugeordneten Kontakte werden betätigt und überbrücken beispielsweise eine mittels Schrittschaltwerk über eine Welle in serialer Folge schaltbare Tarifstufenumschaltung. Das wirkt sich in einem praktischen Anwendungsfall beispielsweise so aus, daß während eines Zeitbereiches, in welchem nur der Tarif II zur Anwendung kommen soll, das Taxametergerät durch den Einschalteffekt sich über den Tarif I hinweg unmittelbar auf den Tarif II einstellt. Diese Einrichtung dient vornehmlich der Gleichstellung der Fahrer untereinander und verhindert gleichzeitig eine nicht erlaubte Tarifumschaltung auf höhere Tarifstufen. Sie bringt jedoch keine wesentliche Erleichterung oder Sicherung im Austausch der wechselseitigen Informationen zwischen der Taxizentrale und dem einzelnen Taxifahrer.In order to achieve equality for all drivers with regard to compliance with the current tariff level at a given point in time, DE-AS 2 037 048 has disclosed an automatically controllable tariff switching device. This device serves primarily the purpose of switching to so-called special tariffs, such as night, weekend, holiday tariffs and the like, without the driver being able to influence them. This device is designed as an additional unit for the existing radio intercom. For the duration of the range of validity of a special tariff, the central tariff switching signals are emitted at regular time intervals, which control an electronic time relay of a time circuit into self-retention. The contacts assigned to the relay circuit are actuated and bridge, for example, a tariff level switch which can be switched in series by means of a step switch via a shaft. In a practical application, this has the effect, for example, that during a time range in which only tariff II is to be used, the taximeter device adjusts itself directly to tariff II through tariff I through tariff I. This device primarily serves to ensure that drivers are treated equally and prevents unauthorized tariff switching to higher tariff levels. However, it does not significantly facilitate or secure the exchange of the mutual information between the taxi center and the individual taxi driver.

Das Dokument EP-A-0 079 401 beschreibt ein Verfahren und eine Schaltung in einem elektronischen Taxameter zur optimalen Verteilung einer Funktionszuweisung für den folgenden Zustand auf die vier verfügbaren Bedientasten. Das hierzu gezeigte Display ist üblicherweise Teil des Taxametergehäuses und als solches ausschließlich in taxameterspezifische Anzeigefelder, wie Fahrpreis, Zuschlag, Taxe usw. aufgeteilt, so daß eine Anzeige hiervon abweichender Informationen und Daten nicht möglich ist.Document EP-A-0 079 401 describes a method and a circuit in an electronic taximeter for optimally distributing a function assignment for the following state to the four available control buttons. The display shown for this purpose is usually part of the taximeter housing and as such is only divided into taximeter-specific display fields, such as fare, surcharge, tax, etc., so that information and data deviating from this is not possible.

Ein aus der GB-A-1 602 274 bekanntes Taxametergerät stellt ebenfalls ein autonomes Gerät ohne jede Peripherie dar und ist in einer Baueinheit zusammengefaßt und ausschließlich vom Fahrer bedienbar im Sinne der Errechnung und Anzeige eines Fahrpreises. Dieses Gerät weist zusätzlich eine Vorrichtung auf, bei der über eine Lochkarteneingabe Fahrzeugdaten und Tarifkonstanten vom Fahrer in das Taxametergerät eingebbar sind; dies geschieht jedoch ohne Einflußnahme bzw. Kommunikation mit der Zentrale. Auch hierbei handelt es sich um einen Taxameter, der als Einzelgerät im Fahrzeug installiert ist und ausschließlich der Handhabung durch den Fahrer unterworfen ist; d. h. er weist keine getrennten Mittel auf für eine Korrespondenz mit einer Zentralen, noch ist eine direkte Auswertung von Fahrtdaten in einer zentralen EDV durchführbar.A taximeter device known from GB-A-1 602 274 also represents an autonomous device without any peripherals and is combined in one structural unit and can only be operated by the driver in the sense of calculating and displaying a fare. This device additionally has a device in which vehicle data and tariff constants can be entered by the driver into the taximeter device by means of a punch card input; however, this happens without any influence or communication with the head office. This is also a taximeter, which is installed as a single device in the vehicle and is only subject to handling by the driver; d. H. it does not have any separate means for correspondence with a central office, nor can travel data be evaluated directly in a central EDP.

Die Druckschrift DD-A-209 922 beschreibt einen elektronischen Taxameter mit Quittungsausgabe. In einem Blockschaltbild sind symbolisch die internen Verbindungen der Baugruppen für die Eingabe-, Anzeige- und Ausgabeeinheit mit der Mikrorecheneinheit angegeben.The document DD-A-209 922 describes an electronic taximeter with receipt output. The internal connections of the modules for the input, display and output unit with the microprocessor unit are symbolically indicated in a block diagram.

Die Aufgabe der Erfindung besteht darin, eine je nach Erfordernis kombinierbare Anlage für Taxifahrzeuge bereitzustellen, die eine gesicherte, vom Taxifahrer weitgehend unabhängige Koordination zwischen einer Taxizentrale und einer Anzahl ihr angeschlossener Taxifahrzeuge erlaubt und einer wechselseitig steuerbaren Übermittlung und Protokollierung von Informationen und Daten dient, dergestalt daß mit einer zentralen Einflußnahme eine optimierte Einsatzsteuerung durchführbar ist.The object of the invention is to provide a system for taxi vehicles that can be combined as required, which allows a secure, largely independent of the taxi driver coordination between a taxi center and a number of connected taxi vehicles and serves a mutually controllable transmission and logging of information and data that an optimized operational control can be carried out with a central influence.

Die Lösung besteht aus einem mobilen Datenterminal für ein Taxifahrzeug, das gekennzeichnet ist durch eine in einem Taxifahrzeug installierbare Kombination aus einzelnen, getrennt voneinander installierbaren Modulen, bestehend aus einem Modul für eine Zentraleinheit mit einem integrierten Taxametermodul, einem internen Programmspeicher, einem Datenspeicher und mit mehreren Eingabe-Ausgabe-Schnittstellen, weiter aus einem Sende/Empfangsterminal für eine wechselseitige Übertragung von Taxameterdaten, Steuerinformationen und Verbalanweisungen, aus einem Display-Terminal, das als eigenständige Anzeigeeinrichtung ausgebildet und einbaubar ist, aus einem Druckerterminal und aus einem Lesemodul für die Auswertung von auf Datenträgern bereitgestellten Daten und Informationen.The solution consists of a mobile data terminal for a taxi vehicle, which is characterized by a combination of individual, separately installable modules that can be installed in a taxi vehicle, consisting of a module for a central unit with an integrated taximeter module, an internal program memory, a data memory and several Input-output interfaces, further from a send / receive terminal for a mutual transmission of taximeter data, tax information and verbal instructions, from a display terminal, which is designed and can be installed as an independent display device, from a printer terminal and from a reading module for the evaluation of Data and information provided to data carriers.

Weitere Merkmale zur Ausgestaltung der Erfindung sind in den Unteransprüchen enthalten.Further features for the embodiment of the invention are contained in the subclaims.

Ein wesentlicher Vorteil der Erfindung liegt in dem modularen Aufbau der angegebenen Kombination begründet. Eine prozessorgesteuerte Zentraleinheit als Kernstück des mobilen Datenterminals weist alle erforderlichen Schnittstellen auf, die einen schrittweisen Ausbau bzw. einen bedarfsmäßigen Anschluß der in modularer Technik erstellten Terminals ermöglichen. Durch diese Konzeption ist über die Zentraleinheit mit einem integrierten Taxametermodul die Basis für eine mobile Datenstation in einem Taxifahrzeug geschaffen, die über die Standardfunktion eines Taxameters hinaus den Weg für neue zusätzliche Taxameterfunktionen öffnet. Durch die Verbindung mit einem Sende-Empfangs-Terminal ist eine Kommunikation mit einer in der Taxizentrale installierten Datenverarbeitungsanlage herstellbar, wodurch ein weit verzweigbarer Zusatznutzen ableitbar ist. Neben den taxameterspezifischen Funktionsabwicklungen, wie automatische Tarifsteuerung, abrufbare Transportaufträge und Kostenvorausberechnungen, Arbeitszeitkontrolle, Schichtabrechnung, Wirtschaftlichkeitsanalyse usw., ist eine Zusatznutzung beispielsweise denkbar in der Form eines Abrufs und der Anzeige von Fahrplandaten anderer Verkehrsmittel durch das variabel ansteuerbare Display-Terminal im Taxifahrzeug. In ähnlicher Weise lassen sich von der Taxizentrale Informationen über Veranstaltungen abrufen oder beispielsweise Vorauskalkulationen des ungefähren Fahrpreises für eine bestimmte Zielfahrt einholen, auf dem Display anzeigen oder gar auf einem Drucker-Terminal ausdrucken. Insbesondere bei Textübertragung von der ortsfesten Taxizentrale an die mobile Zentraleinheit und umgekehrt bei Datenübermittlung zurück an die Taxizentrale gewährleistet das Druckerterminal, das auf automatischen Quittungsbetrieb schaltbar ist, eine gesicherte, kontrollierbare Datenübermittlung. Schließlich ist die Zentraleinheit mit einer Schnittstelle versehen zum Anschluß eines Lesemoduls für die Auswertung von Wertkarten oder Berechtigungsausweisen.An essential advantage of the invention lies in the modular structure of the specified combination. A processor-controlled central unit as the centerpiece of the mobile data terminal has all the necessary interfaces, which enable the terminals created using modular technology to be expanded or connected as required. This concept creates the basis for a mobile data station in a taxi vehicle via the central unit with an integrated taximeter module, which opens the way for new additional taximeter functions beyond the standard function of a taximeter. By connecting to a transceiver terminal, there is communication with one in the taxi center installed data processing system can be produced, whereby a widely branchable additional benefit can be derived. In addition to the tax-specific functions, such as automatic tariff control, callable transport orders and cost projections, working time control, shift accounting, economic analysis, etc., additional use is conceivable, for example, in the form of a call and the display of timetable data for other means of transport through the variably controllable display terminal in the taxi vehicle. In a similar way, information about events can be called up from the taxi center or, for example, a preliminary calculation of the approximate fare for a specific destination can be obtained, shown on the display or even printed out on a printer terminal. The printer terminal, which can be switched to automatic acknowledgment mode, ensures secure, controllable data transmission, particularly when transmitting text from the fixed taxi center to the mobile central unit and vice versa when transmitting data back to the taxi center. Finally, the central unit is provided with an interface for connecting a reading module for evaluating value cards or authorization cards.

Die vom Taxifahrzeug abhängigen Daten gelangen von einem Gebermodul über eine weitere Schnittstelle direkt in die Zentraleinheit und werden dort verzweigt einerseits in das Taxametermodul zur programmgesteuerten Ermittlung eines Fahrpreises, andererseits werden diese Daten zur Übermittlung und Protokollierung von Taxifahrzeugdaten in einer Datenverarbeitungsanlage in der Taxizentrale bereitgestellt.The data, which is dependent on the taxi vehicle, goes directly from a donor module via an additional interface to the central unit, where it is branched on the one hand into the taximeter module for program-controlled determination of a fare, and on the other hand, this data is made available for the transmission and logging of taxi vehicle data in a data processing system in the taxi center.

Ein Ausführungsbeispiel der Erfindung ist nachstehend anhand einer Prinzipdarstellung des modularen Aufbaus des mobilen Datenterminals erläutert.An exemplary embodiment of the invention is explained below on the basis of a basic illustration of the modular structure of the mobile data terminal.

Um ein mobiles Datenterminal an die verfügbaren Einrichtungen der Datenerfassung und Datenverarbeitung anzubinden und ein systemfähiges Konzept zu entwickeln, ist es von wesentlicher Bedeutung, daß die einzelnen Funktionseinheiten für das Erfassen, Verarbeiten, Übertragen, Anzeigen, Protokollieren usw. in modularer Technik aufgebaut sind. Je nach Erfordernis der Datenerfassung entsteht dann eine im Taxifahrzeug aus einzelnen Modulen kombinierbare Anlage. Kernstück eines mobilen Datenterminals ist eine Zentraleinheit 1 mit integriertem Taxametermodul. Die Zentraleinheit 1 enthält einen Programmspeicher und einen Datenspeicher zur Zwischenspeicherung von Informationen. Zum Anschluß von Systemperipherie an die Zentraleinheit 1 sind mehrere Schnittstellen 2, 3, 4, 5, 6 angeordnet, über welche mittels getrennter Leitungsverbindungen 7, 8, 9, 10, 11 Peripherieeinheiten anschließbar sind. Entsprechend ist über eine Leitung 7 ein Gebermodul 12 mit der Schnittstelle 2 der Zentraleinheit 1 verbindbar zur Übernahme von vom Taxifahrzeug abhängigen Daten. Eine Leitungsverbindung 8 führt über die Schnittstelle 3 in der Zentraleinheit 1 an ein Sende-Empfangs-Terminal 13. Eine Leitungsverbindung 9 ist vorgesehen für den Anschluß eines Lesemoduls 14 mit der Schnittstelle 4 der Zentraleinheit 1 zur Übernahme von Daten aus einer Wertkarte oder Identkarte 18. Eine Leitung 10 führt vort der Schnittstelle 5 der Zentraleinheit 1 zu einem Druckerterminal 15 zur programmgesteuerten Protokollierung sowohl intern ermittelter Daten in der Zentraleinheit 1 als auch von Daten aus einer ortsfesten Taxizentrale 19. Schließlich ist eine Schnittstelle 6 angeordnet für die Auskopplung aller Informationen über eine Leitungsverbindung 11 auf ein Anzeigefeld 17 eines Display-Terminals 16. Eine Übertragung von Informationen zwischen der ortsfesten Taxizentrale 19 und dem mobilen Datenterminal im Taxifahrzeug und umgekehrt erfolgt über eine Umsetzung von Ditigalsignalen in frequente Sende- und Empfangssignale.In order to connect a mobile data terminal to the available data acquisition and data processing facilities and to develop a system-compatible concept, it is essential that the individual functional units for recording, processing, transmitting, displaying, logging etc. are constructed using modular technology. Depending on the requirements of data acquisition, a system can then be combined from individual modules in the taxi vehicle. The core of a mobile data terminal is a central unit 1 with an integrated taximeter module. The central unit 1 contains a program memory and a data memory for the temporary storage of information. For the connection of system peripherals to the central unit 1, several interfaces 2, 3, 4, 5, 6 are arranged, by means of which separate peripheral connections 7, 8, 9, 10, 11 peripheral units can be connected. Correspondingly, a transmitter module 12 can be connected via a line 7 to the interface 2 of the central unit 1 in order to take over data dependent on the taxi vehicle. A line connection 8 leads via the interface 3 in the central unit 1 to a transceiver terminal 13. A line connection 9 is provided for the connection of a reading module 14 to the interface 4 of the central unit 1 for taking over data from a prepaid card or identity card 18. A line 10 leads before the interface 5 of the central unit 1 to a printer terminal 15 for program-controlled logging of both internally determined data in the central unit 1 and data from a fixed taxi center 19. Finally, an interface 6 is arranged for the decoupling of all information via a line connection 11 on a display field 17 of a display terminal 16. A transfer of information between the fixed taxi center 19 and the mobile data terminal in the taxi vehicle and vice versa takes place via conversion of digital signals into frequency transmit and receive signals.

Hierzu ist in der Zentraleinheit 1 ein Funkmodem vorgesehen. Die Übertragung von Textinformationen oder Taxametersteuerdaten von der Taxizentrale 19 zu einem mobilen Datenterminal erfolgt über den Sprechfunkkanal alternativ zum Sprechfunkverkehr. Der Sprechfunkverkehr wird dabei wenig beeinträchtigt, da die Übertragungszeiten sehr kurz sind. Für den Funk-Wechselsprechverkehr ist eine handliche Mikrofon-Lautsprecher-Kombination 20 vorgesehen, die über ein steckbares Kabel 21 mit dem Sende/Empfangsterminal 13 verbunden ist. Bei zentraler Einsatzsteuerung der Taxifahrzeuge sind die im Taxametermodul der mobilen Zentraleinheit 1 auslösbaren Funktionen, wie Ein/Ausschaltung, Tarifwahl, Datenanzeige, Quittungsdruck und dergl. mittels Funksignale aus der ortsfesten Taxizentrale 19 steuerbar. Entsprechend sind von der ortsfesten Taxizentrale 19 ausgegebene Informationen im Anzeigefeld 17 des Display-Terminals 16 darstellbar. Darüber hinaus sind diese Informationen und die über den Taxametermodul in der Zentraleinheit 1 ermittelten Daten auf einem Belegstreifen 22 des Druckerterminals 15 ausdruckbar. Selbst wenn ein Taxifahrer sich augenblicklich nicht in seinem Fahrzeug aufhält oder bei einem laufenden Fahrauftrag seine Aufmerksamkeit auf das Verkehrsgeschehen gerichtet ist, erhält er die Information auf einem Beleg abgedruckt in der Form einer schriftlichen Mitteilung. Durch einen Hörfehler bei Auftragserteilung über Sprechfunk beispielsweise falsch interpretierbare Informationen sind damit völlig ausgeschaltet.For this purpose, a radio modem is provided in the central unit 1. The transmission of text information or taximeter control data from the taxi center 19 to a mobile data terminal takes place via the radio communication channel as an alternative to radio communication. The radio communication is hardly affected because the transmission times are very short. A handy microphone-loudspeaker combination 20 is provided for the radio two-way traffic, which is connected to the transmitting / receiving terminal 13 via a pluggable cable 21. When the taxi vehicles are operated centrally, the functions which can be triggered in the taximeter module of the mobile central unit 1, such as on / off switching, tariff selection, data display, receipt printing and the like, can be controlled by means of radio signals from the fixed taxi center 19. Correspondingly, information output by the fixed taxi center 19 can be displayed in the display field 17 of the display terminal 16. In addition, this information and the data determined via the taximeter module in the central unit 1 can be printed out on a document strip 22 of the printer terminal 15. Even if a taxi driver is not in his vehicle at the moment or his attention is focused on the traffic situation during a current driving order, he receives the information printed on a receipt in the form of a written message. Information that can be misinterpreted, for example, due to a hearing error when placing an order via radiotelephony is thus completely switched off.

Die für einen Taxibetrieb erforderlichen Funktionen für die Bedienung des Taxametermoduls in der Zentraleinheit 1 sind auch wahlweise über autonome, in der mobilen Zentraleinheit 1 integrierte Betätigungsmittel 23 auslösbar. Hierzu sind beispielsweise vier Funktionstasten 24, 25, 26, 27 in der Zentraleinheit 1 vorgesehen, mittels welchen die nach einem im System-ROM des Taxametermodul hinterlegten Programm initiierbaren Funktionsschritte auslösbar sind. Beim Erreichen bzw. vor einer Überschreitung der Reichweite des Funkrufsystems ist mittels einer Übertragung eines Signalcodes von der ortsfesten Taxizentrale 19 die Zentraleinheit 1 in einem Taxifahrzeug auf einen Autonombetrieb umstellbar. Diese Umschaltbarkeit auf eine autonome Betriebsweise ist erforderlich für eine Nutzung des mobilen Datenterminals außerhalb der Reichweite des Funkrufsystems in der ortsfesten Taxizentrale 19. Zum Erhalt der Daten im mobilen Datenterminal sind die gesamten Daten in Zwischenspeichern der Zentraleinheit 1 ablegbar und/oder über das Druckterminal 15 protokollierbar.The functions required for a taxi operation for operating the taximeter module in the central unit 1 can also optionally be triggered via autonomous actuating means 23 integrated in the mobile central unit 1. For this purpose, for example, four function keys 24, 25, 26, 27 are provided in the central unit 1, by means of which the program can be initiated according to a program stored in the system ROM of the taximeter module Function steps can be triggered. When the range of the paging system is reached or before it is exceeded, the central unit 1 in a taxi vehicle can be converted to autonomous operation by means of a transmission of a signal code from the fixed taxi center 19. This switchability to an autonomous mode of operation is necessary for using the mobile data terminal outside the range of the paging system in the fixed taxi center 19. To receive the data in the mobile data terminal, the entire data can be stored in intermediate stores of the central unit 1 and / or can be logged via the print terminal 15 .
