Problems solved by technology

However, the coverage of FM radio signals is limited, which is not conducive to the use of large-scale coverage
[0003] Increasing the coverage of the transmitter requires increasing the power of the transmitter, which will bring a great increase in cost

Embodiment Construction

[0018] Below according to the attached figure 1 Describe the specific implementation. Such as figure 1 The technology shown includes: RDS receiving module 1 , voice control unit 2 , transmitter 3 , turntable control unit 4 , PC 5 , and intelligent terminal 6 .

[0019] In normal mode, the RDS receiving module 1 receives the RDS FM signal, demodulates the voice signal and the RDS data signal and outputs them to the voice control unit 2 and the control terminal 4 for the transfer station respectively, and then these two signals are respectively input into the transmitter 3 , to perform modulated transmission, and the RDS receiving module 1 can be controlled by its corresponding superior transmitter.

[0020] In the case that the RDS receiving module 1 is not powered on, and one of the PC 5 and the intelligent terminal 6 (the two cannot work at the same time) is in the working state, the control unit 4 of the differential turntable will select which of the two is working at t...

Abstract

The invention provides a remote data service (RDS) data signal differential transposing technology which mainly solves the difficulty that a wide range of coverage of a RDS data broadcasting system is hard to achieve. The remote data service (RDS) data signal differential transposing technology can not only achieve coverage use at a large range (including villages and remote areas) but also reduce cost. A voice central control unit can control a voice output mode according to the priority level of a control signal. A control terminal of a differential transposing station is capable of controlling the voice output modes of the voice central control unit and a RDS signal and having the function of human-computer interaction. The output priority level of a RDS data signal and a voice signal can be set. The receiving end of the RDS signal can support multiple communication protocols and set the priority level.

Description

technical field [0001] The invention relates to a technique for differential transfer of RDS data signals. Background technique [0002] RDS (radio data system) is a data broadcasting system. RDS is a data service proposed by the European Broadcasting Union (EBU) to provide display and control information for stations in the FM band, so as to improve the functions of FM receivers and make the operation of FM stations more friendly. In the RDS data broadcasting system, the subcarrier of the radio station on the FM (frequency modulation) broadcast signal multiplexes the RDS data such as the station name, program type and program content and sends them out as digital signals, and the RDS receiver can not only pass sound but also These digital signals are represented by images. However, the coverage of FM radio signals is limited, which is not conducive to the use of large-scale coverage. [0003] Enlarging the coverage of the transmitter requires increasing the power of the ...
