Description
Technical field
The present invention relates to a kind of RDS data signal difference rotary device, belong to datacasting field.
Background technology
RDS (radio data system) is Radio Data System, and RDS is a kind of data service, is by Europe broadcast connection
Alliance (EBU) proposes, it is therefore an objective to the radio station for FM frequency range provides display and the information of control, to improve the function of FM receiver, makes
The operation in FM radio station is more friendly, in RDS Radio Data System, and broadcasting station subcarrier on FM (frequency modulation) broadcast singal
The multiplexing RDS data such as station name, program category and programme content send with digital signal, and RDS receiver is not only
These digital signals can also be presented by image by sound.But the limited coverage area of FM broadcast singal, no
It is beneficial to cover use on a large scale.
The coverage increasing transmitter is accomplished by increasing the power of transmitter, and this can bring about the increasing on the biggest cost
Add, realize covering on a large scale if, with taking signal is differed from the technology turned, it is possible to greatly reduce cost, this
The technology of kind has only to signal is received transfer, uses multiple low power transmitter (frequency is different) to carry out subregion transmitting,
Thus can realize covering use on a large scale.
Summary of the invention
In order to solve the problems referred to above, the present invention provides a kind of RDS data signal difference rotary device, reduces RDS data with this
Broadcast system covers the cost of use on a large scale.
Technical scheme is as follows: this invention is provided with RDS receiver module, the Voice command list being connected by wire
Unit, transposer station are with controlling terminal, PC, intelligent terminal, transmitter.
Described RDS receiver module (multiple): receive RDS broadcast, voice-and-data signal difference is transferred out.
Described speech control unit: according to control signal instruction output different phonetic mode.
Described transposer station is with controlling terminal: according to setting two priority classes speech control unit voice output and RDS data
The way of output of signal, selects the output input as transmitter of different input equipment end, stores RDS data signal, and RDS believes
Number incoming end supports various communications protocols.
Described PC: output voice signal and RDS data signal (passing through various communications protocols).
Described intelligent terminal: output voice signal and RDS data signal (passing through various communications protocols).
Described transmitter (multiple): voice signal and RDS data signal modulate emission again are gone out, the frequency of transmitter
Rate is different.
The RDS receiver module that the present invention provides receives RDS data signal, and transfer output, and voice central control unit can
Two priority classes voice output mode according to control signal, transposer station can be according to two priority classes voice central authorities by control terminal
Control unit and the way of output of RDS signal, and possess human-computer interaction function, RDS data signal and voice signal output are excellent
First level can set, and RDS signal incoming end supports various communications protocols, and can carry out the setting of priority.
In the present invention speech control unit according to the priority of control signal for the voice output of RDS receiver module, PC
Voice output, the voice output three of intelligent terminal select one of which as transmitter audio frequency input.
In the present invention, transposer station can control the audio frequency way of output of speech control unit by control terminal, selects RDS to receive
The RDS data output of module, the RDS data output of PC, the RDS data output three of intelligent terminal select one of which as sending out
Penetrate the RDS data input of machine.
The invention has the beneficial effects as follows: have only to signal is received transfer, use the small-power that multiple frequency is different
Transmitter carries out subregion transmitting, it is possible to realize covering use on a large scale.
Accompanying drawing explanation
Accompanying drawing 1 is the population structure block diagram of the present invention,
In figure: 1, RDS receiver module, 2, speech control unit, 3, transmitter, 4, transposer station's control unit, 5, PC, 6,
Intelligent terminal.
Detailed description of the invention
1 further illustrate specific implementation below in conjunction with the accompanying drawings, as it is shown in figure 1, this device includes: RDS receiver module
1, speech control unit 2, transmitter 3, transposer station's control unit 4, PC 5 and intelligent terminal 6.
In the normal mode, RDS receiver module 1 receives RDS FM signal, demodulates voice signal and RDS data signal
Export respectively to speech control unit 2 and transposer station's control terminal 4, during then both signals are separately input to transmitter 3,
Being modulated launching, RDS receiver module 1 can be controlled its switch by higher level's transmitter of its correspondence.
In the case of RDS receiver module 1 is not keyed up work, and PC 5 and intelligent terminal 6 alternative one (the two can not
Work simultaneously) in running order, an equipment that transposer station's control unit 4 can select the most to work
The output of RDS data and voice output are as the input of transmitter, and now these signals will be modulated launching by transmitter 3.
If RDS receiver module 3 and PC 5 and intelligent terminal 6 alternative one (the two is not simultaneously operable) are all in start
Duty, according to priority, transposer station will judge that the RDS data selecting RDS receiver module 1 export and language with controlling terminal 4
Sound output is as the input of transmitter 3.RDS data and voice that RDS receiver module 1 is demodulated out by transmitter 3 are carried out again
Modulate emission.
If RDS receiver module 1 is in duty, and now PC 5 and intelligent terminal 6 alternative one (the two can not
Work simultaneously) send RDS data with emergent instruction, transposer station can carry out the judgement of priority with controlling terminal 4, and automatically will
The PC 5 being outputted to working of transmitter 3 and the output of intelligent terminal 6 alternative one.Then transmitter 3 can be to PC
The RDS data output of machine 5 and intelligent terminal 6 alternative one and voice output are modulated launching.
If PC 5 and intelligent terminal 6 alternative one (the two is not simultaneously operable) are in running order, and now RDS connects
The RDS data that receipts module receives are with emergent instruction, and transposer station is with controlling the priority that terminal 4 meeting foundation sets, the most
Whether the RDS data of the PC 5 of work and the output of intelligent terminal 6 alternative one are with emergent instruction, all by the input of transmitter 3
It is switched to the output of RDS receiver module.Then these voice signals and data signal are modulated launching by transmitter 3.
RDS data signal and voice signal output priority can be set by transposer station's control unit.
The communication protocol of RDS data signal incoming end can be carried out by the human-computer interaction function of transposer station's control unit
The setting of access priority.
