Utility model content
Place in view of above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a kind of based on satellite communication
Intercom system, it is intended to simplify the intercom system, and higher safety is provided.
In order to achieve the above object, the utility model takes following technical scheme：
A kind of intercom system based on satellite communication comprising：Sequentially connected voice module, audio codec, height
Lead to module and defends logical module；
The voice module is used for the input and output of audio signal；
The audio codec is for converting audio signals into analog audio signal or digital audio and video signals；
The high pass module is used to remove the interference signal in audio signal, and for compressing or parsing the audio letter
Number；
It is described to defend logical module based on satellite network for receiving audio signal and sending audio signal.
Preferably, the voice module includes for receiving extraneous analog audio signal and being delivered to audio coding decoding
Device, or for receiving the analog audio signal and broadcasting that the audio codec is sent.
Preferably, the audio codec is specific：
Analog audio signal for receiving the voice module, and the analog audio signal is converted into digital audio and video signals
After be delivered to high pass module；And
Digital audio and video signals for receiving the high pass module, and the digital audio and video signals are converted into analogue audio frequency letter
Voice module is delivered to after number.
Preferably, the high pass module includes main mic and secondary mic, and the main mic and secondary mic is worked at the same time to solve sound
Interference signal in frequency signal.
Preferably, the high pass module is additionally operable to receive digital audio and video signals and the pressure that the audio codec is sent
Contracting；And for receiving the digital audio and video signals for defending logical module transmission and parsing.
Preferably, the digital audio and video signals for defending logical module for receiving high pass module conveying and pass through satellite network
Network is sent to the external world；And the digital audio and video signals of extraneous conveying are received based on satellite network and send supreme logical module.
Compared with prior art, the beneficial effects of the utility model：The utility model by high pass module directly and Wei Tongmo
Block is connected, at the same increase an audio codec, extraneous voice by audio codec export to high pass module into
The processing of row audio signal, while the data/address bus for defending logical module is directly connected to high pass module, you can to realize by defending
The normal voice communication of StarNet's network.
Description of the drawings
Fig. 1 is a kind of module frame chart of the intercom system preferred embodiment based on satellite communication of the utility model.
Fig. 2 is a kind of principle frame of the intercom system preferred embodiment high pass module based on satellite communication of the utility model
Figure.
Specific implementation mode
To keep the purpose of this utility model, technical solution and effect clearer, clear, develop simultaneously implementation referring to the drawings
The utility model is further described in example.It should be appreciated that specific embodiment described herein is only explaining this practicality
It is novel, it is not used to limit the utility model.
A kind of intercom system based on satellite communication provided by the utility model, refers to Fig. 1-2, as shown, described
Intercom system includes：
Sequentially connected voice module 10, audio codec 20, high pass module 30 and defend logical module 40.
In the utility model embodiment, digital audio and video signals are converted into voice module 10 by audio codec 20（Such as：
Loud speaker）Analoging sound signal needed for playing, and pass through voice module 10（Such as：Microphone）Carry out the extraneous audio of storage
When signal, then opposite process is executed.Other common voice modules 10 being connect with audio codec 20 include wear-type
Headset, earphone, microphone, audio input output line etc..
Further, the audio codec 20 also provides mixer（mixer）Function believes all these audios
Number mixing is output and input, and controls the volume in relation to audio signal.
Secondly inside high pass module 30, main mic and secondary mic work at the same time to solve the existing echo of output in communication process,
It utters long and high-pitched sounds and the problem of the interference signals such as noise floor.
The high pass module 30 is built-in with ADSP comprising：
ASM：The interface communicated with DSP ASM；The mechanism that PCM data is routed to DSP is provided, after support is each flowed
Processing/pretreatment；
ADM：ADM services are enabled on DSP, COPP and route matrix are configured, with audio alignment database（ACDB）Communication,
The COPP of appropriate calibration data is configured, and ASM session ids are routed to ADM sessions；
AFE：Enable the AFE services on DSP, activation/deactivate audio hardware port；
