Signal
Embodiment
With reference to Fig. 1, network multi-level associating power supply device can multichannel make up, multistage comprehensive, this device circuit theory diagram one, center feed device (1) is converted to direct current 12V-48V low-voltage with alternating current 220V, by twisted-pair feeder or other light current route supply power voltage and signal are transferred to the next stage node, to convert switch at the corresponding levels or other network equipment circuits needed voltage to through direct current in the about 12V-48V scope in step-down decay back by node adapter L4962 (2), as 5V-9V, adapter transfers to N level with signal and power supply to next stage by internal wiring and Ethernet interface simultaneously.
The network node adapter is divided into internally-arranged type and externally positioned type, internally-arranged type is seen Fig. 2, consist of: electronic circuit is assembled in network device internal, the duplex feeding power supply is set, one the tunnel is the 220V transformation rectification of common usefulness, and another route center feed device makes the 12V-48V Dc low voltage power supply of input be converted to the needed DC power supply of this equipment.
Externally positioned type node adapter is seen Fig. 3, signal and the needed power supply of this equipment can be inputed to next information point through twisted-pair feeder or other light current circuit equally, and the adapter of this model is applicable to the various external power supply type network equipments that using at present.
Can realize that by circuit identification is switched automatically, make it have the function of using two kinds of power supplys, if two kinds of power supplys satisfy simultaneously, this equipment will preferentially use the 220V alternating current, and adapter provides an other power circuit, can improve the reliability of this equipment.
With Ethernet and Ethernet switch is example, further specifies its operation principle:
One, puts type network multi-level electric supply installation, see Fig. 3.
Four ethernet interface modules (A, B, C, D) are fixing, wherein two pairs of lines of A are merged into two lines (the 7th, 8 of the 4th, 5 of Bai Lan and white palm fibre) use, insert the 12V-48V Dc low voltage power supply after the conversion.
With other four line incoming digital signals of twisted-pair feeder, simultaneously with twisted-pair feeder access network based on ethernet mouth A.
It is constant to keep the digital signal hop, inserts switching equipment from Ethernet interface B; To insert contact adapter L4962 from the circuit (4,5,7,8 pin) that Ethernet interface A comes out, be transformed into the required power supply of switch, be power supply for exchange.
Utilize the twisted-pair feeder (remove white blue the 4th, 5 and white palm fibre the 7th, 8 need not) will be from the digital signal access network based on ethernet mouth C of switch output, keep the constant access network based on ethernet mouth of original position D together with power circuit, transfer to next stage switch Ethernet interface A through twisted-pair feeder again from Ethernet interface D from Ethernet interface A output.
Two, internally-arranged type network multi-level electric supply installation is seen Fig. 2.
Regulation access port (A mouth) at switch, the twisted-pair feeder that access is come by the upper level transmission, 1,2,3,6 transmission of digital signals wherein, 4,5,7,8 transmission low voltage and direct currents, behind access port A, digital signal line is separated with power circuit, the digital signal circuit remains unchanged, and at interface the circuit that the A mouth 4,5,7,8 of switch is inserted is cut off, and power supply inserts auto Recognition and Auto Switching System.
The original power module of switch is cut off in output place, inserts automatic recognition system simultaneously, after convert to behind the nucleus equipment required voltage through L4962 and to power for nucleus equipment.
The low-voltage dc power supply of network interface A output is inputed to 4,5,7,8 circuits of regulation as the Ethernet interface B of output; With original 4,5,7,8 circuitry cuts of Ethernet interface B, export the Ethernet interface A of next stage switch to from Ethernet interface B simultaneously.
