Description
Technical field
The present invention relates to power-supply system, more specifically to bidirectional power supply system in a kind of Ethernet POE.
Background technology
In POE system, there is provided the equipment of power supply is referred to as power supply unit PSE (Power Sourcing
Equipment), it is referred to as powered device PD (Powered Device) using the equipment of power supply.PSE be responsible for by power supply inject with
Too netting twine, and implement the planning and management of power.And powered device PD must is fulfilled for IEEE802.3af for PD in detecting process
In the regulation made of performance (feature).
Due in signal transmission system, other signals typically are converted into network signal, by after network transmission again
Original signal is converted into, there have been paired equipment in：Sending ending equipment and receiving device.Current POE skills
Art can only accomplish that receiving device is configured to PD, or sending ending equipment is configured if sending ending equipment is configured into PSE
For PD, receiving device is configured to PSE, and POE power supplies can only one-way transmission.
The content of the invention
In order to overcome above-mentioned POE power supply can only one-way transmission the problem of, the present invention, which provides, a kind of is based on PSE and PD in POE
The bidirectional power supply method and apparatus of module.
The technical solution adopted for the present invention to solve the technical problems is as described below：Bidirectional power supply in a kind of Ethernet POE
System, in Ethernet POE system, sending ending equipment and corresponding receiving device are each provided with mainboard and are easy to be connected with each other
Network interface terminal, it is characterised in that：Sending ending equipment is configured with PSE modules and PD modules, and corresponding receiving device is accordingly
PD modules and PSE modules are configured with, PSE modules connect with PD modules through normally opened normally closed relay in each equipment, described
Power Entry Module is provided with sending ending equipment or receiving device.
Bidirectional power supply system also includes a PD module detection circuits in a kind of Ethernet POE of the invention described above.
Bidirectional power supply system also includes a connection status indicator lamp control circuit in a kind of Ethernet POE of the invention described above.
In the invention described above, the PSE modules for it is independent can plug 8PIN pin plate.
In the invention described above, the PD modules are integrated on the mainboard of corresponding device.
In the invention described above, the network interface terminal is RJ45 interfaces.
According to the present invention of said structure, its advantage is, present invention can be implemented in Ethernet POE system, makes
When providing power supply with power supply adaptor, (PD is broken when realizing that an equipment uses PSE power supply modules by normally-open normally-close relay
Module), another equipment is by normally-open normally-close relay using PD by electric module (breaking PSE modules), intelligent PSE two-way confession
Electricity.It is final to realize POE power supply transmitted in both directions purposes.
Below in conjunction with the accompanying drawings and embodiment the present invention is described further.
Brief description of the drawings
Fig. 1 is one embodiment of the invention structured flowchart；
Fig. 2 is another example structure block diagram of corresponding diagram 1；
Fig. 3 is instantiation structure principle chart of the present invention.
Embodiment
As shown in Figure 1-2, bidirectional power supply system in a kind of Ethernet POE of the present invention, it is in Ethernet input terminal unit
Signal wire be connected to being above connected with network transformer, power input subelement in the primary side of network transformer in tap；
Power supply and ethernet signal are combined by network transformer, and by PSE lead-out terminals unit export, PD receiving terminals from
Voltage is obtained at the centre tap of network transformer.Every equipment is all integrated with PSE and PD modules in design.Any use
Power supply adaptor is powered, and when realizing one using PSE power supply modules by normally-open normally-close relay, breaks PD modules, Ling Yitai
PSE modules are turned off by normally-open normally-close relay, using PD modules, realize intelligent PSE bidirectional power supplies control system.
The relay of normally-open normally-close, when power supply inserts from any equipment, normally opened switch terminals adhesive is normally closed
Disconnect.So PD is connected on normally closed switch under normality, PSE is connected on above normal open switch.So any one device power when break
PD is opened, RJ45 receiving terminal PD work is given in PSE work.
As shown in figure 3, every equipment of the present invention is all integrated PSE and PD modules, PSE modules are made can plug 8PIN pin
Platelet, PD is then integrated in above mainboard, PD modules using isolation PD electric means.According to the IEEE 802.3af of standard
POE standards, method is bridged using end, data realize that direct current supplies to employing signal isolation transformer, and using centre cap
Electricity.
Power supply unit is by power outlet, and to device power, while relay disconnects the physics with PD ends by adhesive
Connection, PSE module normal works, constantly constantly flashed by RJ45 POE feeder ears detection PD connection, indicator lamp, table
Show in detecting always, accessed if any normal PD equipment, due to there is the relay of normally-open normally-close, PD, which is corrected, to be at PD ends
Under normally closed physical connection state, so after the access of PD equipment, POE PSE modules give PD normal power supplies, export what is set
Maximum supports power, and often bright state, the whole complete procedure that PD equipment completes POE with PSE device are normal for the holding of detection indicator lamp
Work.
It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
Exemplary description has been carried out to patent of the present invention above in conjunction with accompanying drawing, it is clear that the realization of patent of the present invention not by
The limitation of aforesaid way, if the various improvement that the methodology of patent of the present invention and technical scheme are carried out are employed, or without
Improve and the design of patent of the present invention and technical scheme are directly applied into other occasions, within the scope of the present invention.
