Voice data output is arrived radio frequency earphone or loudspeaker by road selecting module；
The route choosing module, using circuit selecting switch, according to the control signal that control module is exported, by vehicle-mounted sound
The voice data for ringing output is sent to loudspeaker or RF receiving and transmission module；
The RF receiving and transmission module, using CC85XX chips, the voice data to receiving carries out power amplification, signal and turns
Change, produce radiofrequency signal, and communicated with radio frequency earphone by radio-frequency antenna, voice data is transferred to radio frequency earphone；
The radio frequency earphone, receives the voice data of RF receiving and transmission module output and plays, and gathers and return the language of user
Message ceases, and through vehicle audio output to user mobile phone, realizes voice communication.
Beneficial effects of the present invention：The onboard wireless RF communication system that the present invention is provided, by setting loudspeaker and penetrating
Frequency earphone two-way audio circuit, route choosing is carried out using route choosing module, user using radio frequency earphone conversed when,
The voice of call is to be transferred on earphone, internal loudspeaker no longer sounding, and after end of conversation, usable switch key makes audio
Recover to be exported from original loudspeaker, solve existing bluetooth earphone can not and sound interactive, both audition when especially driving a vehicle
Ring and answered the call with earphone again, the problem unfavorable to traffic safety.
Brief description of the drawings
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Fig. 1 is system schematic of the invention.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is all other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
As shown in figure 1, the invention provides a kind of onboard wireless RF communication system, including vehicle audio, control module,
Power detection module, power module, shift knob, route choosing module, RF receiving and transmission module and radio frequency earphone.
Vehicle audio, by bluetooth connection user mobile phone, realizes voice communication, and voice data is exported with user mobile phone
To route choosing module.
Power detection module, by power module continued power, for gathering the operating power of vehicle audio, and is sent to
Control module.
Power module, for being powered to each functional module of system.
Shift knob, user selects to play audio using radio frequency earphone or loudspeaker by shift knob.
Control module, using MCU single-chip microcomputers, the vehicle audio operating power of receiving power detection module collection judges car
Sound equipment working condition is carried, when vehicle audio is closed, control power module is only powered to power detection module, when vehicle audio is beaten
When opening, control power module is powered to all functional modules of system；The selection signal of shift knob, control circuit choosing are received simultaneously
Module is selected by voice data output to radio frequency earphone or loudspeaker.
Route choosing module, it is according to the control signal that control module is exported, vehicle audio is defeated using circuit selecting switch
The voice data for going out is sent to loudspeaker or RF receiving and transmission module.
RF receiving and transmission module, using CC85XX chips, the voice data to receiving carries out power amplification, signal conversion,
Radiofrequency signal is produced, and is communicated with radio frequency earphone by radio-frequency antenna, voice data is transferred to radio frequency earphone.CC85XX chips
Powerful, high-quality, short-range 2.4GHz wireless digital audios stream radiofrequency signal can be provided, two or more equipment are formed
PurePath wireless audio networks, it is ensured that audio network can in different environments provide gapless and powerful audio stream, it
