Description

Ein von einem Empfangssystem abgesetztes LTE-Modul  An offset from a receiving system LTE module
Beschreibung description
Die Erfindung betrifft eine Empfangsvorrichtung für ein Fahrzeug. The invention relates to a receiving device for a vehicle.
Bekannte Empfangsvorrichtungen empfangen über zumindest eine Antenne, gegebenenfalls über mehrere Antennen (Diversity) hochfrequente Signale. Die hochfrequenten Signale werden in einer Verarbeitungseinheit umgesetzt (insbesondere von einer Hochfrequenz in eine Zwischenfrequenz), weiterverarbeitet und dann der Darstellung (akustisch und/oder optisch) zugeführt. Known receiving devices receive via at least one antenna, possibly over several antennas (diversity) high-frequency signals. The high-frequency signals are converted in a processing unit (in particular from a high frequency to an intermediate frequency), further processed and then supplied to the display (acoustically and / or optically).
Solche Empfangsvorrichtungen sind in einem Gehäuse angeordnet, welche in einem Fahrzeug an geeigneter Stelle (zum Beispiel im Bereich des Armaturenbrettes) untergebracht sind. Für die Stromversorgung ist es erforderlich, ein Stromversorgungskabel an die Empfangsvorrichtung heranzuführen. Außerdem muss das Kabel von der Antenne, im Regelfall ein Coax-Kabel, zu der Empfangsvorrichtung über lange Wege in dem Fahrzeug verlegt werden. Dies ist jedoch unter hochfrequenztechnischen Aspekten von Nachteil. Such receiving devices are arranged in a housing, which are housed in a vehicle at a suitable location (for example in the area of the dashboard). For the power supply, it is necessary to bring a power supply cable to the receiving device. In addition, the cable from the antenna, usually a coax cable, must be routed to the receiving device over long distances in the vehicle. However, this is disadvantageous in high-frequency technical aspects.
Für die Verarbeitung der hochfrequenten Signale ist es erforderlich, eine Zugangsberechtigung und/oder Abrechnung vorzusehen. Dies wird beispielsweise mit einer SIM-Karte oder dergleichen realisiert. Hierfür ist es erforderlich, dass das Gehäuse für das Einsetzen und den Wechsel der SIM-Karte zugänglich ist. Da solche Empfangsvorrichtungen, insbesondere deren Empfangssysteme, oftmals auf Software-Basis arbeiten, ist es von Zeit zu Zeit erforderlich, die Software auf den neuesten Stand zu bringen (Update) oder die gesamte Empfangsvorrichtung neu zu konfigurieren. For processing the high-frequency signals, it is necessary to provide an access authorization and / or billing. This is realized, for example, with a SIM card or the like. This requires that the case be accessible for insertion and replacement of the SIM card. Since such receiving devices, in particular their receiving systems, often work on a software basis, it is from time to time required to update the software (update) or to reconfigure the entire receiving device.
Es liegt somit grundsätzlich folgende Problemstellung vor: There is thus basically the following problem:
Mehr-Empfangsysteme benötigen Koaxialkabel (Coax Leitungen, auch als HF-Kabel bezeichnet) für die Hochfrequenzsignale. Weiterhin benötigen aktuelle und zukünftige Technologien (wie beispielsweise 4G, 5G, DSRC, WLAN) n-Antennen und somit eine ver-n-fachung von Coax Leitungen (n = Anzahl der Antennen, vorzugsweise n größer 1 ) · Multi-reception systems require coaxial cables (coax cables, also referred to as RF cables) for the high-frequency signals. Furthermore, current and future technologies (such as 4G, 5G, DSRC, WLAN) require n antennas and thus a simplification of coax lines (n = number of antennas, preferably n greater than 1).
Dies führt zu hohen Anforderungen an das HF-Kabel in Bezug auf Gewicht, HF- Dämpfung und Verlegestrategien im Fahrzeug. This leads to high demands on the HF cable in terms of weight, RF attenuation and laying strategies in the vehicle.
HF-Kabel gelten im Automotive-Bereich als kostenintensiv. Leitungslängen haben somit einen für die gesamte Empfangsvorrichtung, insbesondere für den Fahrzeughersteller, finanziellen Aspekt. HF cables are considered to be costly in the automotive sector. Line lengths thus have a financial aspect for the entire receiving device, in particular for the vehicle manufacturer.
Weiterhin führt jede Signalverarbeitung beziehungsweise Prozessierung innerhalb eines Gerätes zu weiteren thermischen Verlusten, welche einen negativen Einfluss auf die Lebenserwartung von einzelnen elektronischen Komponenten haben sowie auch zu reduzierter Empfangsperformance führen kann. Der Erfindung liegt daher die Aufgabe zugrunde, eine bekannte Empfangsvorrichtung zu verbessern. Furthermore, each signal processing or processing within a device leads to further thermal losses, which can have a negative impact on the life expectancy of individual electronic components and can also lead to reduced reception performance. The invention is therefore based on the object to improve a known receiving device.
Diese Aufgabe ist dadurch gelöst, dass das Empfangssystem und ein Empfangsmodul der Empfangsvorrichtung voneinander getrennt (abgesetzt) sind. Dadurch kann das Empfangssystem an geeigneter Stelle in einem Fahrzeug, zum Beispiel im Bereich eines Armaturenbrettes, angeordnet werden. Gleiches gilt für das abgesetzte Empfangsmodul, welches in vorteilhafter Weise in der Nähe der zumindest einen Antenne angeordnet wird. Dadurch kann die Übertragungsstrecke der hochfrequenten Signale kurz gehalten werden. Eine Anordnung des abgesetzten Empfangsmoduls erfolgt bei einem Fahrzeug beispielsweise unter dessen Dach, einem Stoßfänger oder dergleichen. This object is achieved in that the receiving system and a receiving module of the receiving device are separated from each other (deducted). As a result, the receiving system can be arranged at a suitable location in a vehicle, for example in the area of a dashboard. The same applies to the remote receiving module, which is advantageously arranged in the vicinity of the at least one antenna. As a result, the transmission path of the high-frequency signals can be kept short. An arrangement of the remote receiving module takes place in a vehicle, for example, under the roof, a bumper or the like.
Nach der Erfindung ist vorgesehen, dass das Empfangssystem und das abgesetzte Empfangsmodul über eine Verbindungsleitung, insbesondere einem Datenbus, zum Übertragen von Signalen und über eine Stromversorgungsleitung miteinander verbunden sind. Die Übertragung der Signale, vorzugsweise von Daten, zwischen dem Empfangssystem und dem abgesetzten Empfangsmodul erfolgt über eine Verbindungsleitung, vorzugsweise einen Datenbus. Außerdem sind das Empfangssystem und das abgesetzte Empfangsmodul über eine Stromversorgungsleitung miteinander verbunden, sodass das Empfangsmodul von dem Empfangssystem aus mit Energie versorgt wird. Idealerweise erfolgt sowohl die Signalübertragung, insbesondere die Datenübertragung, und die Stromversorgung über eine gemeinsame Leitung. Dies hat darüber hinaus den Vorteil, dass sowohl an dem Empfangssystem als auch an dem Empfangsmodul jeweils nur ein einziger geeigneter Steckverbinder vorzusehen ist, der mit korrespondierenden Gegensteckverbindern an der gemeinsamen Leitung verbunden wird. According to the invention, it is provided that the receiving system and the remote receiving module are connected to one another via a connecting line, in particular a data bus, for transmitting signals and via a power supply line. The transmission of the signals, preferably data, between the receiving system and the remote receiving module via a connecting line, preferably a data bus. In addition, the receiving system and the remote receiving module are connected to each other via a power supply line, so that the receiving module is powered by the receiving system from energy. Ideally, both the signal transmission, in particular the data transmission, and the power supply via a common line. This has the additional advantage that only a single suitable connector is to be provided both on the receiving system and on the receiving module, which is connected to corresponding mating connectors on the common line.
Die Trennung von Empfangssystem und Empfangsmodul hat darüber hinaus den Vorteil, dass ein Standard-Empfangssystem verwendet werden kann und empfangs- oder übertragungsspezifische Gegebenheiten in dem Empfangsmodul vorgesehen werden können. So kann das abgesetzte Empfangsmodul beispielsweise an die Frequenzbereiche, die mit der zumindest einen Antenne empfangen werden, angepasst sein. Darüber hinaus können verschiedene Dienste, wie zum Beispiel Telefon, Datendienste, Navigationssignale und dergleichen) von dem hierfür abgestimmten Empfangsmodul empfangen, weiterverarbeitet und an das Empfangssystem weitergeleitet werden. Diese Verarbeitung erfolgt dabei in vorteilhafter Weise auf eine Art und Weise, dass ein Standard-Empfangssystem eingesetzt werden kann, wobei unterschiedliche Empfangsmodule dazu geeignet und ausgebildet sind, unterschiedliche Frequenzen, unterschiedliche Dienste und dergleichen zu empfangen und zu verarbeiten und derart weiter zu verarbeiten (umzusetzen), dass diese umgesetzten Signale Standardsignale sind, die von dem Standard-Empfangssystem empfangen und weiterverarbeitet werden können. The separation of receiving system and receiving module also has the advantage that a standard receiving system can be used and receiving or transmission-specific conditions can be provided in the receiving module. For example, the remote receiving module can be adapted to the frequency ranges that are received by the at least one antenna. In addition, various services, such as, for example, telephone, data services, navigation signals and the like, can be received, further processed and forwarded to the receiving system by the receiving module which is coordinated therewith. This processing advantageously takes place in a manner such that a standard receiving system can be used, whereby different receiving modules are suitable and designed to receive and process different frequencies, different services and the like and to process them further in such a way ) that these converted signals are standard signals that can be received and processed by the standard receiving system.
Das vorstehend vorgestellte System setzt die FIF-Dienste ortsnah an der Antenne auf digitale Signale um (abgesetzte Baseband Unit) und leitet diese Daten zum Prozessieren an eine abgesetzte Einheit (Domain Controller Unit) weiter. Weiterhin bündelt das vorgestellte System mehrere Technologien auf ein„digitales“ Kabel. The system presented above converts the FIF services close to the location of the antenna to digital signals (remote baseband unit) and forwards this data to a remote unit (Domain Controller Unit) for processing. Furthermore, the presented system bundles several technologies on a "digital" cable.
Vorteile: Geringere Dämpfung des Signalpegels und geringere Leitungslänge führen zu geringerem Gewicht in Bezug auf den Kabelbaum. Advantages: Lower signal level attenuation and shorter cable length result in less weight in relation to the wiring harness.
Das vorgestellte System bündelt die Daten von mehreren Diensten (somit mehrere HF Coax Kabel) auf eine digitale Leitung, welche sich im Fahrzeug leichter verlegen lässt (beispielsweise MiMo 4G/5G 4x Coax Kabel, DSRC 2x Coax Kabel, GNSS 1 x Coax Kabel und dergleichen). The presented system bundles the data from several services (thus several HF coax cables) onto a digital line, which is easier to lay in the vehicle (eg MiMo 4G / 5G 4x Coax Cable, DSRC 2x Coax Cable, GNSS 1 x Coax Cable and the like).
Die digitalen Signale werden in besonders vorteilhafter Weise in einer abgesetzten, thermisch weniger anspruchsvollen Umgebung im Fahrzeug für den Nutzer umgesetzt und aufbereitet. The digital signals are converted and processed in a particularly advantageous manner in a remote, less thermally demanding environment in the vehicle for the user.
Ein Ausführungsbeispiel für die Erfindung ist im Folgenden beschrieben und anhand der Figur gezeigt. An embodiment of the invention is described below and shown with reference to the figure.
In der Figur ist mit der Bezugsziffer 1 eine Empfangsvorrichtung schematisch dargestellt, die dazu geeignet und ausgebildet ist, hochfrequente Signale in einem Fahrzeug zu empfangen, weiter zu verarbeiten und darzustellen. In the figure, the reference numeral 1, a receiving device is shown schematically, which is adapted and adapted to receive high-frequency signals in a vehicle to further process and display.
Die Empfangsvorrichtung 1 weist ein Empfangssystem 2 auf, mit dem Signale, Daten oder dergleichen empfangen werden und dargestellt (zum Beispiel optisch und/oder akustisch) und/oder abgegeben werden können. The receiving device 1 has a receiving system 2 with which signals, data or the like are received and displayed (for example visually and / or acoustically) and / or can be dispensed.
Die hochfrequenten Signale werden mittels zumindest einer Antenne 3 empfangen. Die zumindest eine Antenne 3 ist mit einem von dem Empfangssystem 2 abgesetzten Empfangsmodul 4 verbunden. Der Bauraum, in dem das Empfangssystem 2 angeordnet ist, und der Bauraum, in dem das Empfangsmodul 4 angeordnet ist, unterscheiden sich und sind auf Distanz zueinander. The high-frequency signals are received by means of at least one antenna 3. The at least one antenna 3 is connected to a remote from the receiving system 2 receiving module 4. The space in which the receiving system 2 is arranged, and the space in which the receiving module 4 is arranged, differ and are at a distance from each other.
Das Empfangssystem 2 ist beispielsweise im Bereich eines Armaturenbrettes eines Fahrzeuges angeordnet, wohingegen das abgesetzte Empfangsmodul 4 zum Beispiel unterhalb eines Daches des Fahrzeuges eingebaut wird. The receiving system 2 is arranged for example in the region of a dashboard of a vehicle, whereas the remote receiving module 4 is installed, for example, below a roof of the vehicle.
Das abgesetzte Empfangsmodul 4 weist eine elektronische, fest eingebaute SIM-Karte 5, eine externe SIM-Karte 6, eine Verarbeitungseinheit 7 und optional eine Diagnoseeinheit 8 auf. Für die externe SIM-Karte und/oder die interne (elektronische) SIM-Karte kommen entsprechend geeignete Ausführungsformen (wie zum Beispiel auch USIM-Karte) in Betracht. The remote receiving module 4 has an electronic, permanently installed SIM card 5, an external SIM card 6, a processing unit 7 and optionally a diagnostic unit 8. For the external SIM card and / or the internal (electronic) SIM card correspondingly suitable embodiments (such as USIM card) come into consideration.
Die mit der zumindest einen Antenne 3 empfangenen hochfrequenten Signale werden der Verarbeitungseinheit 7 zugeführt, dort weiterverarbeitet und an eine Schnittstelle des Empfangsmodul 4 weitergeleitet. Für die Berechtigung bzw. Abrechnung, dass die empfangenen hochfrequenten Signale mittels des Empfangsmodul 4 weiterverarbeitet werden können, sind die eSIM-Karte 5 und/oder eine externe Karte 6, die in das Empfangsmodul 4 von außen eingesetzt werden kann, vorgesehen. The high-frequency signals received by the at least one antenna 3 are supplied to the processing unit 7, further processed there and forwarded to an interface of the receiving module 4. For the authorization or billing that the received high-frequency signals can be further processed by the receiving module 4, the eSIM card 5 and / or an external card 6, which can be used in the receiving module 4 from the outside, are provided.
Die Verarbeitungseinheit 7 bereitet die ihr zugeführten hochfrequenten Signale auf, verarbeitet sie und stellt sie ebenfalls der Schnittstelle des Empfangsmodul 4 zur Verfügung. Über diese Schnittstelle werden die bereitgestellten Signale, zum Beispiel Datenpakete, über eine Verbindungsleitung, vorzugsweise einen Datenbus 9, übertragen und an das Empfangssystem 2 weitergeleitet. Weiterhin sind das Empfangssystem 2 und das Empfangsmodul 4 über eine Stromversorgungsleitung 10 miteinander verbunden. Idealerweise sind der Datenbus 9 und die Stromversorgungsleitung 10 in einem Kabel zusammengefasst, an dessen Enden sich jeweils ein Steckverbinder befindet, wobei der jeweilige Steckverbinder in einen Gegensteckverbinder in dem Empfangssystem 2 und dem Empfangsmodul 4 eingesteckt werden kann. Dadurch wird es in vorteilhafter Weise ermöglicht, dass das Empfangssystem 2 und das Empfangsmodul 4 über eine größere Distanz zueinander in dem Fahrzeug angeordnet werden können und sich der Verkabelungsaufwand deutlich verringert. Außerdem ist der Vorteil gegeben, dass das Empfangsmodul 4 sehr nahe bei der zumindest einen Antenne 3 angeordnet werden kann, um hochfrequenztechnische Probleme, die aufgrund größerer Entfernungen zwischen der Antenne und dem Empfangsmodul entstehen könnten, wirksam zu vermeiden. The processing unit 7 prepares the high-frequency signals supplied to it, processes them and also makes them available to the interface of the receiving module 4. About this interface, the signals provided, for example, data packets, via a connecting line, preferably a data bus 9, transmitted and forwarded to the receiving system 2. Furthermore, the receiving system 2 and the receiving module 4 are connected to each other via a power supply line 10. Ideally, the data bus 9 and the power supply line 10 are combined in a cable, at the ends of each a connector, wherein the respective connector can be plugged into a mating connector in the receiving system 2 and the receiving module 4. This advantageously makes it possible for the receiving system 2 and the receiving module 4 to be arranged at a greater distance from one another in the vehicle and for the cabling effort significantly reduced. In addition, there is the advantage that the receiving module 4 can be arranged very close to the at least one antenna 3 in order to effectively avoid radio frequency technical problems that could arise due to greater distances between the antenna and the receiving module.
In vorteilhafter Weise ist das Empfangsmodul 4 als ein LTE-Modul ausgebildet und das Empfangssystem 2 ist dazu geeignet und ausgebildet, um eine Kommunikation zu weiteren Geräten innerhalb des Fahrzeuges drahtgebunden und/oder drahtlos zu realisieren. Insbesondere weist das Empfangssystem 2 (nicht dargestellt) Übertragungsmittel auf, über die das Empfangssystem 2 mit Geräten innerhalb des Fahrzeuges (wie zum Beispiel Smartphones, Tablets oder dergleichen) kommunizieren kann. Hierbei versteht es sich von selbst, dass die Datenübertragung nicht nur von der zumindest einen Antenne 3 über das abgesetzte Empfangsmodul 4 und das Empfangssystem 2 hin zu dem Gerät innerhalb des Fahrzeuges erfolgt, sondern dass die Übertragung bidirektional ausgeführt ist. Das bedeutet, dass auch von einem Gerät innerhalb des Fahrzeuges Signale über das Empfangssystem 2 und über das Empfangsmodul 4 über die zumindest eine Antenne 3 abgegeben werden können. In diesem Fall ist die zumindest eine Antenne 3 nicht nur eine Empfangsantenne, sondern auch eine Sendeantenne. Advantageously, the receiving module 4 is designed as an LTE module and the receiving system 2 is suitable and designed to realize a wired and / or wireless communication with other devices within the vehicle. In particular, the receiving system 2 (not shown) has transmission means by which the receiving system 2 can communicate with devices within the vehicle (such as smartphones, tablets or the like). It goes without saying that the data transmission is not only from the at least one antenna 3 via the remote receiving module 4 and the receiving system 2 to the device within the vehicle, but that the transmission is bidirectional. This means that signals can also be output from a device within the vehicle via the receiving system 2 and via the receiving module 4 via the at least one antenna 3. In this case, the at least one antenna 3 is not only a receiving antenna but also a transmitting antenna.
