Specific embodiment
Reach technological means and effect that predetermined purpose is taken for the present invention is expanded on further, below in conjunction with accompanying drawing and reality
Apply example to the specific embodiment of the present invention, architectural feature and its effect, describe in detail as follows.
As shown in figure 1, a kind of hand-held satellite telephone system structural representation with function of wireless talkback of the present invention, one
Plant the hand-held satellite phone with function of wireless talkback, including CPU, microphone, receiver 2, digital keys 3, display screen 4, SIM 5
With battery 6, microphone 1 access CPU phonetic entry end, receiver 2 audio input end is connected with CPU audio output, digital keys 3,
Display screen 4 and SIM 5 are all connected with CPU；Battery 6 is connected with cpu power management interface, wherein, also includes by serial ports
Intercom module 8 that UART-B and pcm audio bus are connected with CPU and by serial ports UART-A and pcm audio bus with CPU even
The satellite transceiver module 9 connecing, serial ports UART-B and serial ports UART-A be used for realizing intercom module 8 and satellite transceiver module 9 with
Instruction interaction between CPU, pcm audio bus is used for realizing transmitting voice signal；Intercom module 8 passes through radio frequency SMA interface
It is connected with for realizing the interphone antenna 10 that intercommunication signal receives and sends, satellite transceiver module 9 is by rf signal line even
It is connected to for realizing satellite signal receiving and the satellite antenna 11 sending；It is right for realizing that CPU key-press input test side is connected with
Say the intercommunication button 7 of machine speech function.
Preferably, this satellite phone also includes loudspeaker 12, SD card 13 and usb 14, loudspeaker 12 audio input end
It is connected with CPU audio output, be used for realizing audio signal outer sound broadcasting；SD card 13 is connected with CPU, for data storage；USB
Interface 14 is connected with CPU, for equipment charge and data transfer；This device display screen 4 is LCD display.
It is defaulted as satellite phone pattern after this device power-up, dial satellite telephone signals transmission step：Pressed by numeral
Key 3 dials to CPU；CPU forms call instruction, and is sent to satellite transceiver module 9 by serial ports UART-A；Satellite transceiver module
This call instruction is modulated into radio frequency satellite-signal by 9 is sent to satellite antenna 11, and Waiting for Call response；Satellite transceiver module 9
Receive the answer signal that callee is returned by satellite, and be demodulated to response instruction and send CPU to；It is total that CPU connects pcm audio
Line is to satellite transceiver module 9；User talks from microphone 1, and sound is input to CPU, and CPU to its capturing and coding and passes through pcm bus
It is sent to satellite transceiver module 9, be sent to called mobile phone eventually through satellite；Meanwhile, satellite transceiver module 9 receives callee
The voice signal being sended over by satellite, sends CPU to by pcm audio bus after it is demodulated, CPU is eventually through receiver
2 or loudspeaker 12 other side's voice signal is reduced to user.
Answer satellite telephone signals transmission step：Satellite transceiver module 9 receives the calling that calling party is sent by satellite
Signal, and be demodulated to call instruction and send CPU to；CPU returns response and instructs to satellite transceiver module 9, is also turned on pcm audio
Bus, to satellite transceiver module 9, i.e. closing of the circuit, realizes call.
Intercom and satellite phone function are integrated：It is defaulted as satellite phone pattern, when user needs after this device power-up
During intercommunication, can open and intercom is set by three kinds of modes and realize intercommunication function.Intercom is partly relative only with satellite phone
Vertical, voice call passage can not use simultaneously.Intercommunication process does not affect satellite phone and monitors incoming call, needs temporarily during satellite phone call
Stop intercommunication sound.When intercommunication process has satellite incoming call, equipment ejects whether prompting answers satellite incoming call, selects "No" to continue right
Say, select "Yes" incoming call answering, auto-returned intercom pattern after on-hook, until user exits intercom pattern manually.So,
User can flexibly switch voice channel according to actual conditions.
The unlatching of talkback mode：First, by shortcut, with duration press volume "+" "-" key, when screens switch is to intercommunication
During interface, button frequency modulation is added and subtracted to frequency by volume, starts intercommunication；Second, enter phone setting interface, select " intercom ",
Choosing " opening intercom ", then adds and subtracts button frequency modulation to frequency by volume；3rd, open intercom application software complete right
Say machine start frequency modulation operation.After frequency modulation is provided with, need to select to click on " confirmation " and arrange just can come into force, sound after confirming simultaneously
Amount plus-minus button recovers acquiescence.When opening for the second time, repeat one of three of the above mode.
Intercom pattern intercommunication signal transmission step：Pin intercommunication button 7；CPU connects pcm audio bus to intercom mould
Block 8；User is talked by microphone 1, and sends intercom module 8 to by CPU；Spoken sounds are modulated by intercom module 8
Default frequency range, and it is sent to other pairing intercoms in neighbouring same frequency range by interphone antenna 10.
Intercom pattern answers signal transmission step：Interphone antenna 10 receives default frequency range intercommunication signal nearby and gives
Intercom module 8；Intercom module 8 is sent to CPU to after the demodulation of this voice signal by pcm bus；CPU passes through loudspeaker 12
Reduce this voice signal.
Above content is to further describe it is impossible to assert with reference to specific preferred embodiment is made for the present invention
Being embodied as of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of present inventive concept, some simple deduction or replace can also be made, all should be considered as belonging to the present invention's
Protection domain.
