Description
Technical field
The utility model is related to a kind of intercom, and in particular to a kind of public network intercom, belongs to intercom technical field.
Background technology
With Intelligent hardware popularization and LTE network it is perfect, domestic many companies start to have done DMR digital intercoms melts
The composite machine of LTE public network intercommunications is closed, Fiberhome telecommunication, general day communication and Haikang satellite TV are just belonging to this type substantially；Hardware
Design be exactly with high pass or MTK LTE hardware as platform, then inside hand-held set superposition DMR intercommunication modules；Structure is in shell
Top, designs DMR helical antennas very long；Software is with android as platform, and exploitation DMR intercommunications software application and LTE intercommunications are soft
Part application；Universal Problems are exactly hand-held set bulky, also want exterior DMR helical antennas, are worn very inconvenient；DMR pairs
Say that power consumption is very big, whole machine radiating is difficult treatment；If client only selects LTE public network intercommunications, then DMR modules are not just any
Meaning, but client cannot make a choice again, increased the use cost of client；In order to solve the above-mentioned technical problem, Chinese patent
Application number：201620346429.0 disclose a kind of LTE public networks intercom, including the DMR digital intercoms hand-held microphone being independently arranged and
LTE public network intercoms, are docked, DMR numbers between the DMR digital intercoms hand-held microphone and LTE public network intercoms by M6 physical interfaces
Word intercommunication hand-held microphone includes DMR digital intercom modules, miaow head, loudspeaker and PTT buttons, and LTE public network intercoms are with MTK6735 as hardware
Platform, comprising LTE intercommunication hardware components；The control of DMR digital intercoms application software and LTE are set in the LTE public networks intercom
Public network intercommunication controls application software；The utility model designs inside hand-held microphone DMR intercommunication modules, then LTE public network intercommunications
The small and exquisite exquisiteness that machine can just do, and there is no DMR heat dissipation problems；Apolegamy product is made into DMR intercommunications, for client with regard to many
A kind of choice, reduces the overall use cost of client；It is also used as hand-held microphone to use, is brought great convenience to client；
But its construction cost is high, signal easily produces fluctuation distortion, and can only carry out real-time Communication for Power, difficult to use to some occasions.
Utility model content
To solve the above problems, the utility model proposes a kind of public network intercom, low production cost can switch in real time
To timing intercommunication module of making peace, communication stabilization.
Public network intercom of the present utility model, including lead to the TCP/IP networks of network high in the clouds speech talkback server communication
Letter module, the TCP/IP network communication modules communicate to connect master controller；The master controller communication link is connected to microphone electricity
Road, speaker circuit, the keyboard control circuit of control keyboard, usb communication circuit, flash storage and LCDs；It is described
Microphone circuit electrically connects microphone；The speaker circuit electrically connects loudspeaker；The master controller is electrically connected with timing and opens
Close and time regulator；Intercommunication terminal is connected to using TCP/IP links by network high in the clouds speech talkback server, when a terminal
When initiating calling, voice is converted into data signal by compression first, and speech talkback server is uploaded to by TCP/IP networks,
The all terminals of marshalling same with initiating terminal are forwarded the data to after server analysis data；Each terminal decompresses number after being connected to data
According to reduction voice, one time intercom calls terminate；During work, it is defaulted as sending state in real time, after pressing time switch, system enters
Recording state, now, the microphone circuit entered by microphone is turned data by the A/D converter that master controller is carried
Flash storage is delivered to after changing data signal into；And entry time adjuster interface, adjustment is timed, when timing is arrived
Afterwards, the data in flash storage are uploaded to speech talkback server.
Used as preferred embodiment, the master controller is made up of STM32F103ZE controllers and its peripheral circuit.
Used as preferred embodiment, the keyboard control circuit is made up of ZLG7290 chips and its peripheral circuit.
Used as preferred embodiment, the master controller is also electrically connected with recording call buttons, press recording call by
Button, master controller is coordinated, and flash storage data are delivered into the D/A converter that master controller is carried.And by data by raising one's voice
Device circuit is sent out.
Compared with prior art, public network intercom of the present utility model is normal by conventional public network intercom for the utility model
The DSP devices of use replace with the arm processor of the Cortex-M3 frameworks with certain computing capability, and simple structure is produced into
This is low, can switch in real time to timing intercommunication module of making peace, and communication stabilization can be well adapted for each environmental demand.
Brief description of the drawings
Fig. 1 is overall structure block diagram of the present utility model.
Specific embodiment
As shown in figure 1, public network intercom of the present utility model, including with network high in the clouds speech talkback server communication
