Block 7 is received by serial ports, and direct information ambe-1000 is decoded after receiving by controller module 7 by I/O mouth, solves
Information after Ma send D/A modular converter 9 to carry out digital-to-analogue conversion again, then promotes sound horn by power amplifier, restores sound letter
Breath.
Down-hole is completely the same with above-mentioned work process to aboveground communication process, repeats no more.
Downhole optic fiber phone is similar with above-mentioned work process, the most in detail to calling and the call engineering of ground optical fiber telephone
State.
(2), during two the optical fiber telephone terminal communications in down-hole, it is installed on ore deposit with the calling of ground mine digital optical fiber telephone 1
As a example by No. two mine digital optical fiber telephones 4 of down-hole, press No. two mine digital optical fiber telephone 4 correspondences being installed under mine
Button, is installed under mine mine digital optical fiber telephone 3 internal controller module 7 and monitors call button when pressing,
I.e. sent the call instruction of corresponding optical fiber telephone address by serial ports, this call instruction contains MPTY address and called party
Address, instruction transmitted by optical transceiver module 6, then by 8*1 optical branching device arrive ground optical fiber telephone light receive and dispatch
Integrated module, be converted to electricity digital signal after, controller module 7 by serial ports receive this order, when discovery oneself not by
During the side of crying, then information being forwarded by serial ports, this call instruction can arrive all optical fiber telephones in down-hole, down-hole digital telephone
The instruction received is analyzed by internal controller module, No. two mine digital optical fiber telephones 4 being only installed under mine
Address corresponding, then the controller module being installed under mine No. two mine digital optical fiber telephones 4 sends bell signal, simultaneously
Lighting the display lamp that calling party is corresponding, being used for indicating calling party is a mine digital optical fiber telephone 3.If scene has people to connect electricity
Words, then enter call flow, and the sound of the mike being installed under mine No. two mine digital optical fiber telephones 4 is turned by A/D
Die change block 12 is converted into digital signal, encodes subsequently into ambe-1000, and the transmission of speech information after coding is to controller
Module, controller module 7 issues the integrated module of optical transceiver by serial ports, and now voice messaging is transformed to digitized optical signal and passes
Defeated, first it is transferred to ground optical fiber telephone, then voice messaging is forwarded by ground optical fiber telephone again, arrives a mine digital
Being transformed to digital signal by optical transceiver module 6 after optical fiber telephone 3, then controller module 7 is received by serial ports, controls
Direct information ambe-1000 is decoded after receiving by device module 7 by I/O mouth, and decoded information send D/A to change again
Module 9 carries out digital-to-analogue conversion, then promotes sound horn by power amplifier, restores acoustic information.A number mine digital optical fiber electricity
Mike's transmission of speech information flow process of words 3 is consistent with above-mentioned flow process, forwards again by ground optical fiber telephone, the most superfluous
State.
