Description

Ethernet electric power relay system, feeder equipment and access bridge-set
Technical field
The present invention relates to a kind of system and device, be meant a kind of Ethernet electric power relay system, feeder equipment and access bridge-set especially.
Background technology
POE (Power Over Ethernet; PoE) refer under existing Ethernet wiring architecture; When transmitting the electronic product (like IP phone machine, wireless network access point, web camera etc.) that a network data to meets the Ethernet specification by a netting twine; Can also utilize this netting twine provide one be direct current network electric power (36V～57V) meets the technology of the electronic product of Ethernet specification to this; Thus, just can obtain needed electric power, and need not extraly again be connected to other Power Supplier or battery obtains required electric power as long as this electronic product that meets the Ethernet specification connects this netting twine.POE also is called as the LAN electric power system, and (Power Over LAN POL) or active formula Ethernet (Active Ethernet), has kept the compatibility with existing Ethernet system and user.IEEE 802.3af standard is the new standard of POE system, and being has increased the directly relevant criterion of power supply of netting twine on the basis of IEEE 802.3at, is the expansion of existing ethernet standard, also is first international standard about power distribution.
Like Fig. 1 and shown in Figure 2, according to IEEE 802.3af standard, a complete POE system comprises: a POE equipment 21, an Ethernet power receiving equipment 22, and a netting twine 23.
This POE equipment 21 comprise a power supply generator (Power Sourcing Equipment, PSE) PSE, two transformers 31,32, and one have first to the 8th pin 1～8 connectivity port (for example RJ45 connectivity port).
This Ethernet power receiving equipment 22 comprise one receive electric transducer (Powered Device, PD) PD, two transformers 33,34, and one have first to the 8th pin 1～8 connectivity port (for example RJ45 connectivity port).
This netting twine 23 comprises four pair cables 35,36,37,38.
This pair cable 35 is connected in first, second pin 1 of first, second pin and this Ethernet power receiving equipment 22 of this POE equipment 21, between 2.
This pair cable 36 is connected in the 4th, the 5th pin 4 of the 4th, the 5th pin and this Ethernet power receiving equipment 22 of this POE equipment 21, between 5.
This pair cable 37 is connected in the 7th, the 8th pin 7 of the 7th, the 8th pin and this Ethernet power receiving equipment 22 of this POE equipment 21, between 8.
This pair cable 38 is connected in the 3rd, the 6th pin 3 of the 3rd, the 6th pin and this Ethernet power receiving equipment 22 of this POE equipment 21, between 6.
Again, there are two kinds of supply power modes in this POE system, and a kind of is terminal cross-over connection method (End-Span; Like Fig. 1 and shown in Figure 2), in transmitting network data, transmit a network electric power to Ethernet power receiving equipment 22, below will further specify terminal cross-over connection method; Another kind then is mid-span method (Mid-Span; As shown in Figure 3), (Midspan PSE) comes transmission network electric power through mid-span POE equipment 21, because of the connected mode of mid-span method is similar to this end cross-over connection method; Can consult IEEE 802.3af standard, so do not repeat.
Terminal cross-over connection method can be divided into two kinds; A kind of is first and second pin 1,2 and 3,6 power supplies (as shown in Figure 2) of the 3rd, six pins through POE equipment 21, another kind of then be fourth, fifth pin 4,5 and the 7th, eight pins 7,8 through POE equipment 21 supply power (as shown in Figure 1).
As shown in Figure 1; When POE equipment 21 is supplied power through fourth, fifth pin 4,5 and the 7th, eight pins 7,8; Fourth, fifth pin of this POE equipment 21 is connected to the positive pole of power supply generator PSE; The 7th, eight pins 7,8 of this POE equipment 21 then are connected to the negative pole of power supply generator PSE; Fourth, fifth pin 4,5 of this Ethernet power receiving equipment 22 is connected to the positive pole that receives electric transducer PD again, and the 7th, eight pins 7,8 of this Ethernet power receiving equipment 22 then are connected to the negative pole that receives electric transducer PD.
As shown in Figure 2; When POE equipment 21 is supplied power through first and second pin 1,2 and the 3rd, six pins 3,6; Power supply generator PSE supplies power to the mid point of this transformer 31,32 with the centre tap mode; And receive electric transducer PD to be connected to the mid point of this transformer 33,34 with the centre tap mode, and not influencing network data transmission, first and second pin 1,2 and the 3rd, six pins 3,6 can be any polarity.
According to IEEE 802.3af standard, POE equipment 21 can only be supplied power through one of them mode of Fig. 1 and Fig. 2, but Ethernet power receiving equipment 22 must can two kinds of situation of simultaneous adaptation.Such requirement is not difficult to reach as far as the Ethernet power receiving equipment 22 of 10Mbs and 100Mbs, and reason is that this kind Ethernet power receiving equipment 22 only uses first and second pin 1,2 and the 3rd, six pins 3,6 receiving network datas.Therefore, can design the Ethernet power receiving equipment 22 that is applicable to Fig. 1 and two kinds of situation of Fig. 2 simultaneously easily.
Yet along with the evolution of network technology, the Ethernet wiring can have been supported the transmission rate to 1000Mbs.Yet; Must use all pair cable transmitting network datas in the application of 1000Mbs; Make the defined POE of Fig. 1 to Fig. 3 system can't satisfy the application of 10Mbs, 100Mbs and 1000Mbs simultaneously, thereby limited the development of POE system.
Again; Above-mentioned POE system is used for a pair of multiduty a kind of existing implementation and also has expensive problem, below lifts two example shows, and first example is as shown in Figure 4; A kind of network electric power source cell S 1 with a POE equipment 21 respectively via the netting twine 23 of two long distances be connected to two be positioned at the same area electronic product P1, P2; This two electronic product P1, P2 respectively have an Ethernet power receiving equipment 22, and this network electric power source cell S 1 transmits a network data by this two netting twine 23 and a network electric power arrives this two electronic product P1, P2, still; Draw the way of the netting twine 23 of two long distances, cause increasing cost.
Second example; As shown in Figure 5; For above-mentioned POE system is used for the existing implementation of a pair of multiduty another kind; Be with above-mentioned difference: also increase by an Ethernet access bridge-set (Access Point; AP) AP1, this Ethernet access bridge-set AP1 have POE equipment 21 that a netting twine 23 via a long distance is connected to this network electric power source cell S 1 and are connected to the POE equipment 21 of this two electronic product P1, P2 with the Ethernet power receiving equipment 22 that receives this network data and network electric power and respectively via two short-range netting twines 24; This Ethernet access bridge-set AP1 with this network data shunting back and the electric power that utilizes the POE equipment 21 of this Ethernet access bridge-set AP1 to be produced be stated from these on the network data of shunting to output to this two electronic product P1, P2 respectively; Though save netting twine 23 costs of a long distance, still, this Ethernet access bridge-set AP1 uses comparatively expensive POE equipment 21 and this Ethernet power receiving equipment 22; Also can cause increasing cost; Again, up to the network electric power of 36V～57V want advanced horizontal high voltage change low pressure could as the required electric power of Ethernet access bridge-set AP1 (5～12V), so this Ethernet access bridge-set AP1 also needs a step-down controller (figure does not show) and more increases hardware cost.
