Description
WO 99/13591 PCT/DE98/01568 Receiver in an antenna base Prior Art The invention relates to a receiver, in particular to a radio receiver for installation in a motor vehicle whose receiving part, connected to an antenna, is separated spatially from other components of the receiver and has the characteristics of a receiving part for a radio receiver according to the type in the independent patent claims.
A receiving system for radio is known from DE 43 03 110 Al consisting of antenna amplifier, tuner and audio-frequency section. In order to avoid the usually expensive laying of the antenna cable from the antenna amplifier or antenna to the receiving part and for the reduction of disturbances of the received high-frequency radio signal prone to disturbance in the course of its transmission over the antenna cable, a splitting up of the usual connection of tuner and audiofrequency amplifier to the advantage of an immediate spatial connection of antenna and amplifier to a circuit module and an arrangement of this unit in an appropriate part of the motor vehicle body is suggested.
Advantages of the invention The receiver of the invention with the characteristics of the main claim has, against prior art, the advantage that by means of the spatial connection of the receiving part of a (radio) receiver including the tuner to the antenna, the antenna cable between antenna and antenna amplifier can be avoided. By this means, an increased insensitivity over prior art of the received radio signal to disturbances which may arise results.
Furthermore, in the case of a radio receiver intended for installation in a motor vehicle the search for an appropriate installation position for the receiving part and also the possibly difficult installation in the appropriate position is avoided by means of the integration of the receiving part in the antenna base of the antenna.
WO 99/13591 PCT/DE98/01568 A further advantage exists in that the receiving part can be bound in by means of a connection for control and/or useful data in a complex communication network in the vehicle which can contain further so-called external components such as, eg. a compact disc player or a receiver for GPS signals alongside the components of a customary communication network in the vehicle.
In the operating piece designed as an interface between the user and communication network there is space for other functions or components which results from the moving of the receiving part including the tuner components to the antenna base.
By means of the measures listed in the subclaims, advantageous extensions and improvements of the receiver or receiving parts described in the independent claims are possible.
It is an advantage, therefore, that the receiving part is connected via the connection for control data to the operating part and with further components. With appropriate networking for the data such as audio data, the possibility of parallel use of signals of various audio sources simultaneously at various positions in the vehicle results.
By means of spatial separation of the receiving part from the operating piece and the other components of the receiver, the danger of a severe mutual disturbance of the tuner and the device processors occurring is decreased.
Drawing Embodiment examples of the invention are shown in the drawing and are described in some detail in the following. Shown are: Figure 1 an antenna in whose antenna base a receiving part of a receiver is arranged, Figure 2 a block diagram of the receiving part arranged in the antenna base of the antenna and comprising the tuner and the networked components in a motor vehicle. Figure 3 Description of an embodiment Figure 1 shows an antenna 2 using the example of a motor vehicle antenna usually arranged on the roof of a motor vehicle in the form of a short rod antenna. This features an antenna base 3 which is situated directly on the metal of the body 8 of the vehicle. In another embodiment of the invention, it is also seen to that the antenna base 3 is arranged below the body metal and only the antenna 2 U S
OFF\C
WO 99/13591 PCT/DE98/01568 3 itself is directed through the metal to the outside.
A receiving part 1 for a radio receiver installed in the vehicle is arranged in the antenna base 3 of the antenna 2, in the present embodiment the receiving part 1 connected to the antenna 2 and the antenna base 3 being removable for the purpose of simplified repairs or an exchange of components (antenna receiving part).
The receiving part 1 has a current supply connection 7, a connection 5 for control data and another connection 6 for data which, in the present case, are led in the form of lines through bores in the motor vehicle body to the inside of the vehicle.
Figure 2 shows the circuit of the reception part 1 which is connected to the antenna 2. The output of the antenna 2 is situated on the input of a preamplifier 10 for the high frequency reception signals, in the case of a radio receiver of the received radio signals. The output of the preamplifier is connected to the receiver circuit 11 in the following indicated as tuner 11. The output of the receiver circuit 11 is directed into a coding circuit 12 which in turn is connected to an interface circuit 15, the output of which corresponds to the further connection 6 for data. The receiver circuit 11 features an additional connection to a microcontroller 14 which in turn is connected to a bus interface 13.
The microcontroller 14 with the receiving part 1 assumes all the control functions in such a way that, for example, commands given by the operating piece 20 of the radio receiver such as, for example, a transmitter change in corresponding control signals for the tuning of the tuner to another transmission frequency are changed.
The bus interface 13 has a connection 5 for control data. The high frequency antenna signal received by the antenna 2 is amplified in the preamplifier 10 and directed to the receiver circuit 11. It makes available the reception signal in a standard format which is changed by a coder circuit 12 connected upstream which is suited to transmission over long distances. Such a format is given, for example, through IEC 958 which enables a transmission over several meters, eg. over distances between the antenna with receiving part and data drain. Before the signal is transmitted over the data line 26 connected to the further connection 6 for useful signals, it is matched in the interface circuit to the conditions of the transmission path. The transmission of data in the data line 26 is possible both over the screened lines and over fibre-optic light guides. An interface circuit 15 is necessary in both cases. In the first case a potential separation must be undertaken in the circuit, in the second a signal conversion of the electric signal in an optical signal is necessary. The controlling of the receiving part 1, ie. especially of the receiver circuit 11 takes place over a bus interface 13 and the microcontroller 14. The reception circuit 11 is activated when the user wishes SWO 99/13591 PCT/DE98/01568 4 to receive radio data over the control line 25 which is connected to the terminal 5 of the receiving part 1 for control data.
Figure 3 shows a simple example of the communication network in a motor vehicle consisting of the operating unit 20 of the receiver, the receiving part 1 of the receiver, further components 21 of the receiver such as the low frequency amplifier for the amplification of the audio signals to be reproduced and a display unit for the display, for example, of the programme name of a currently received radio programme, and, if applicable, to the external components 22 connected to the communication network such as, for example, a play-only machine for compact discs, an additional low frequency amplifier for the amplification of the audio data to be reproduced or a receiver for radio fixing information transmitted by means of the Global Positioning System (GPS) or a navigation device.
The operation unit 20 serves the user for the operation of the communication network. It can be installed in the hitherto usual position of a car radio, having functions of individual components.
The operating part 20 can be designed as a pure operating part or have additional functions such as, for example, a GSM telephone. It is also possible, however, within the framework of the present invention, to integrate a transmission and reception unit of a mobile telephone as well as, for example, a GPS receiver for the collection of navigation data transmitted by means of the Global Positioning System with the receiving part 1 or as part of the same in the antenna base 3 of the antenna 1.
All other components 1, 21 of the receiver installed in the vehicle and the external components 22 connected to the communication network are operated via the operating part 20 and the control line or the control bus In accordance with an extension of the invention, it is also possible to transmit control data or useful data such as, eg. audio data via a common medium such as copper cable or a fibre-optic light guide, both control and useful data accessing the same bus. If the operator wants to hear the radio in the front area of the vehicle while in the rear signals or other audio waves should be emitted, this is possible without further ado. The operator gives the command to the combination of receiving part 1 and antenna 2, to switch reception to active. The radio data are transmitted to a data drain which is suited to the output of data in the front area of the vehicle. Simultaneously the operating unit 20 can operate eg. a compact disc player and output its data flow to another data drain eg. to a loud speaker or headphones arranged in the rear of the vehicle.
