Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the premise of creative work
Lower obtained all other embodiment, belong to the scope of the utility model protection.
As shown in figure 1, the utility model embodiment provides a kind of sonar green end data remote transmission system, including：For gathering
Multiple underwater arrays (1,2 ... .n) of data, the underwater arrays are made up of battle array cable, for gathering underwater data.Multiple first
Photoelectricity Switching Module, each described first photoelectricity Switching Module are connected by netting twine with the underwater arrays.Multiple institutes
State the first photoelectricity Switching Module and be connected to an optical multiplexer, the optical multiplexer is connected to optical demultiplexer, and the photodissociation is answered
One second photoelectricity Switching Module is connected to device, the second photoelectricity Switching Module is connected to a processor by netting twine.It is described
First photoelectricity Switching Module is identical with the structure of the second photoelectricity Switching Module, and photoelectricity Switching Module is denoted as in figure,
Simply distinguished below with digital 1-n and k.
As depicted in figs. 1 and 2, the data collected are passed through network cable transmission to respective photoelectricity interchange mode by multiple underwater arrays
Block 1-n, convert electrical signals to the mutually different optical signal transmission of wavelength and answer each road optical signal to optical multiplexer, optical multiplexer
Use and be transmitted in an optical fiber, the light multiplexing signal of reception is demultiplexed by optical demultiplexer in dry end electro-optical package,
The electric signal transmission collected is restored through photoelectricity Switching Module k conversions to be handled to processor, realizes the up of data
Transmission；Processor order is sent to green end after dry end carries out electro-optic conversion through optical fiber, then is sent out after carrying out opto-electronic conversion by green end
Underwater collecting device is given, realizes the downlink transfer of order.Optical multiplexer, optical demultiplexer and processor therein are existing
Some equipment.
As depicted in figs. 1 and 2, the first photoelectricity Switching Module is identical with the structure of the second photoelectricity Switching Module,
It includes BCM5389 chips, and BCM5389 chips are exchanger chip, and the BCM5389 chips pass through SPI interface and one
MC9S12NE64 chips connect, and realize and BCM5389 chip internal registers are configured and managed.The BCM5389 chips
SPI interface is respectively SCK (serial clock) interface, SS (chip select terminal) interface, MOSI (aggressive mode output, follower mode input)
Interface and MISO (aggressive mode input, follower mode output) interface.BCM5389 runs on slave pattern more, because it is only
Need to carry out response to the read-write requests of master control set.SS interfaces are that low level is effective, therefore SS ends when BCM5389 is written and read
Low level must all be kept.The SPI interface of MC9S12NE64 chips can realize the docking to BCM5389, SCK and SPI-SCK/

State the connection of BCM5389 chips.The BCM5389 chips have 8 Serdes/SGMII adaptive interfaces.
Serdes is the abbreviation of serializer/de-serializers, and its function is that parallel multiple signals are converted to differential serial to pass
Defeated mode, differential transfer are to use both threads transmission signal, and signal amplitude is equal, opposite in phase, compares the two in receiving terminal
The voltage difference of signal is logical zero or logic 1 judge transmitting terminal transmission.Differential serial transmission means have it is low in energy consumption,
The highest transmission speed of the features such as strong antijamming capability, external electromagnetic interference are small, identification is accurate and speed is fast, the in theory interface

It is first powered up, each port of Ethernet switch is initialized.BCM5389 chips are integrated with 8 Serdes/ altogether
SGMII adaptive interfaces, connection backup optical module corresponding interface is arranged into SGMII patterns, and (optical module can only be BCM5389's
Port is arranged to carry out the transmission of data with Ethernet switch during Serdes patterns), other 7 interfaces are both configured to Serdes
Pattern.Link is not carry out switching after the completion of initialization, by the transmission of checking information with receiving the shape to light-path
State is judged, light path is switched over if light path in 2 seconds is not switched on；Otherwise the detection of light-path is carried out always, directly
To path can not use switch over.The switching times in the stipulated time are judged after light-path switching, if in 10 seconds
The number of switching then shows that two light-pathes can not all use more than 2 times, and photoelectricity Switching Module is restarted and circulates above operation；It is no
The break-make detection of light-path is then carried out always, is switched over again until path can not use.Due to optical fiber in the seawater has can
It can be squeezed and bend or other reasonses cause light-path obstructed, and the damage for being not necessarily optical module and optical fiber causes
, it is possible to repeated multiple times switching is carried out to two light-pathes.

For optical-electronic, the function of electrical-optical conversion, the signal received is converted to selected ripple by the photoelectricity Switching Module by DWDM optical modules
Long optical signal, make it possible optical multiplexer by multi-way signal multiplexing into an optical fiber, two optical modules using real
The backup of light-path is showed；The use of chips of Ethernet exchange (BCM5389 chips) can not only complete the redundancy of light-path
Backup and switching, and the data multiplex forwarding that Ethernet switch is realized can also bring more flexible topology, for from now on
It is convenient that extension provides, and transmission data are more at a high speed.The sonar green end data remote transmission system cannot be only used for the green end of sonar, also
It can be applied to other and exchange long-distance transmissions photoelectricity the field for having demand, there is relatively broad application value.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
