RDS is a kind of special radio broadcasting, claim " wireless Data Broadcasting System " (RadioDataSystem), it is in FM broadcasting transmits, utilize subcarrier that station name, program category, programme content and out of Memory are sent in digital form.
RDS, except can issuing above-mentioned message, can also issue emergency information, transport information, advertising message, control information etc.And the terminal presenting these message is limited, part FM broadcast receiver with RDS function, but only supports that self program uses.Major part LED, LCD display terminal cannot support RDS receiving function.
Utility model content
The defect of RDS broadcast singal cannot be received for existing equipment, devise a kind of RDS receiving equipment, make not support that the display terminal of RDS data receiver can receive RDS data.
A kind of wireless Data Broadcasting System (RDS) receiving equipment, the LCD display comprising microprocessor and be connected with microprocessor, LED light, button, RDS receiving circuit, extends out module, Ethernet interface, RS232 serial ports and power supply.Described LCD display, provides device parameter to show information; Button, provides key-press input signal, and signal is sent to microprocessor, and LCD display is combined with button and provides man-machine interaction, carries out optimum configurations to equipment.
LED light, receives microprocessor-based control signal, by light signal indicating equipment operating state.
Microprocessor: by the initial data after demodulation, carries out data check, process, after data being packed, issues relevant device by network interface or RS232 serial ports according to display terminal agreement.
RDS receiving circuit, sends to microprocessor processes by after the analog signal demodulation received from antenna, and supports audio output function, FM broadcast radio function.
Extend out module controls, receive microprocessor-based control signal, by Control external module power supply, realize the control to peripheral module.
Ethernet interface and RS232 serial ports, for exterior terminal connecting interface, RDS data are externally forwarded by network interface or RS232 serial ports.
Described microprocessor, by the initial data after demodulation, carries out data check, process, after data being packed, is externally sent by Ethernet interface or RS232 serial ports according to display terminal agreement.
Described power acquisition DC power supply, transfers the operating voltage of low-voltage circuit and IC to, to adapt to the power demands of each functional module by external adapter 12V direct voltage.
The RDS Data Analysis that this equipment can will receive, according to display terminal protocol forward payload segment content, makes not support that the display terminal of RDS data receiver can receive RDS data.Adding this equipment, can, when not changing existing terminal construction itself, making existing all kinds of LED, LCD display terminal support RDS receives information.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is use syndeton schematic diagram of the present utility model.
Embodiment
Below in conjunction with specific embodiment and Figure of description, the utility model is described in further detail.Specific embodiment described herein only in order to explain the utility model, and is not used in restriction the utility model.
Embodiment: a kind of wireless Data Broadcasting System (RDS) receiving equipment, as shown in Figure 1, the LCD display comprising microprocessor and be connected with microprocessor, LED light, button, RDS receiving circuit, module, Ethernet interface, RS232 serial ports and power supply is extended out.
Power supply, transfers the operating voltage of low-voltage circuit and IC to, to adapt to the power demands of each functional module by external adapter 12V direct voltage.
RDS receiving circuit, supplies microprocessor processes by after the analog signal demodulation received from antenna, and supports audio output function, make this equipment also support FM broadcast radio function.
LED light, reflects the operating state of this equipment, to install and maintenance.
Button and LCD display, provide man-machine interaction, device parameter arranged simpler and easy.
Microprocessor, by the initial data after demodulation, carries out data check, process, after data being packed, issues relevant device by network interface or RS232 serial ports according to display terminal agreement.
Extend out module controls, this part, by Control external module power supply, realizes the control to module.
Ethernet interface and RS232 serial ports, with exterior terminal connecting interface, RDS data are forwarded by Ethernet interface and RS232 serial ports.
As shown in Figure 2, this RDS receiving equipment is as the Signal reception transferring equipment between broadcast transmission station and various peripheral hardware display device (as advertising display devices, building external LED display).RDS receiving equipment receiving broadcast signal, is transmitted to display device and carries out showing, playing after process.Implementation step is as follows.
1. on RDS receiving equipment, configure by button and LCD prompting the display terminal type needing to be connected.
2. select the interface connecting line that terminal is supported, by terminal and this equipment connection.
3. the indicator light of this equipment will indicate connection status and Signal reception state.
4. successful connection after receiving RDS effective information, this equipment, by the agreement of information according to configurating terminal, is forwarded to terminal, information is shown on this equipment LCD simultaneously.
5. the data that will receive by oneself of terminal, reach the function of forwarding.
This RDS receiving equipment possesses RDS message sink, man-machine interaction, information is forwarded to the function of all kinds of LED, LCD display terminal and FM radio receiver.LED, LCD display terminal making major part that RDS cannot be supported to receive, can have RDS receiving function after adding this equipment.Not only broadcast program information can be issued by radio network to display terminal, also emergency information, transport information, advertising message, control information etc. can be issued.
Be the utility model preferred embodiment in sum, all changes made according to technical solutions of the utility model, all belong to protection range of the present utility model when the function of producing does not exceed the scope of technical solutions of the utility model.
