Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Implementing for the present invention is described in detail below in conjunction with specific embodiment：
As shown in figure 1, a kind of photoelectric port multiplex circuit of ethernet device, including：The exchange chip of built-in ethernet mouthful,
Network transformer, RJ45 network interfaces, termination power, optical signal detecting module, optical module and CPU, Ethernet interface pass through network transformation
Device connect RJ45 network interfaces, Ethernet interface through overcoupled circuits connect optical signal detecting module, optical signal detecting module respectively with light
Module and CPU connections, CPU are connected with exchange chip；Ethernet interface provides switch network input/output signal, through network transformation
The power port signal that device is isolated needed for backward RJ45 offers power port, CPU is detected after optical signal detecting module, is actively accessed and is exchanged core
The Ethernet interface of exchange chip is simultaneously configured to optical port mode of operation by piece, and Ethernet interface exports optical signal, and optical signal is via coupling
Optic communication is carried out with outside by optical signal detecting module and optical module after circuit coupling.Here, Ethernet interface is by coupling electricity
Road provides the optical signal after coupling and arrives optical signal detecting module, and optical signal detecting module provides optical module and detects signal to CPU, together
When provide photo-signal channel to optical module.
A kind of photoelectric port multiplex circuit of described ethernet device, refers to Ethernet power port signal via network transformer
RJ45 is directly arrived after isolation, after Ethernet optical port signal is coupled in network transformer front end via termination power, passes through optical signal
Detecting module and the optical module of rear end carry out optic communication.Meanwhile, CPU detects outside in real time by detected light signal detection module
The change of optical electrical interface, and photoelectricity configuration behaviour is carried out to the corresponding ports of ethernet device according to exterior light/electrical interface change
Make, so as to realize the photoelectric multiplexing function of ethernet device.
Exchange chip itself includes multiple Ethernet interfaces that may be configured to light or electrical interface, and CPU is straight with exchange chip
Connect in succession, what CPU confirmed outside access by detection light signal detection module is light or electric signal, and interchanger is carried out
Configuration, allows interchanger output light or electric signal, and after being coupled via termination power and outside is communicated.Interchanger does not have in itself
Which kind of type method identification external interface is, the present invention allows exchange function actively according to outside need to solve this problem
Seek flexible port switching type.In the present invention, termination power solves the problem of two kinds of circuit communications of photoelectricity are compatible, makes two kinds of photoelectricity
Signal can walk different passages, and optical signal detecting module solves the problem of how interchanger recognizes external interface, if CPU is examined
Optical signal detecting module is measured, illustrate outside access is optical interface, then Ethernet interface will be configured to light by exchange chip
Mouthful mode of operation, Ethernet interface output optical signal, optical signal successively coupled circuit, optical signal detecting module and optical module with it is outer
Portion is communicated, and this is the path that optical port signal is walked；If CPU can't detect optical signal detecting module, illustrate outside access
There is no optical interface, now exchange chip will be configured to Ethernet interface power port mode of operation, Ethernet interface exports power port signal,
Power port signal reaches RJ45 network interfaces by network transformer, and this is the path that power port signal is walked.
In other words, whether CPU can detect the presence of optical signal detecting module, determine that Ethernet interface is configured to optical port
Or power port pattern, it is achieved thereby that the multiplexing of port.
In fig. 2, define optical signal detecting module row seat signaling interface, including network signal interface TD+/- and
RD+/-, optical signal detecting module detecting interface DET, optical module signal detection SD, and power supply and signal ground.
In addition, when customizing production, only retain termination power and network transformer on mainboard pcb board, wherein RJ45 and
Optical signal detecting module is used as accessory, is matched and is welded by actual production demand.Mainboard passes through sequential monitoring optical signal first
Detecting module detects interface DET signal, if monitoring, optical signal detecting module has been installed, and program is automatic by switch network
Interface switch to optical port and export the logical signal needed for optical port (RD+/-, TD+/-, SD signals etc.), while being detectd using optical signal
The level shifting circuit surveyed in module, to meet the requirement of optical fiber configured transmission.If mainboard does not monitor optical signal detecting module
Interface DET signal is detected, then switch network interface is configured to power port, while welding RJ45 and supporting the use the net on mainboard
Mouth level shifting circuit, to meet the configured transmission of power port network, is achieved in connecing each network of interchanger on single mainboard
The flexible configuration of mouth, so as to meet the flexible apolegamy of network interface when interchanger is produced to the full extent.
In embodiments of the invention, it can not be met customer need the asking of differentiation to solve to solidify optical port power port technology
Topic, circuit support optical port power port compatibility, and energy hardware notification master chip automatic identification port simultaneously notify software merit rating into phase
The pattern answered, solves the single optical port of Ethernet switch and power port can not coexistent problem.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modifications, equivalent substitutions and improvements made within refreshing and principle etc., should be included in the scope of the protection.
