Abstract
The utility model discloses an intellectual detection system POE power supply, including system power supply, PSE switch and PD equipment, be equipped with DCDC in the system power supply, be equipped with PSE chip and POE power in the PSE switch, be equipped with the PD chip in the PD equipment, system power supply electric connection is in the POE power, POE power electric connection is in PD equipment, signal connection between PD chip and DCDC, signal connection between PSE chip and PD chip, signal connection between PSE chip and POE power. The utility model discloses can realize intelligent power supply, the PSE chip that PD chip in the PD equipment can be followed in the PSE switch learns whether normal the PSE switch is, if DCDC signal among the system power supply can be given to normal PSE chip, DCDC can learn the power consumption of PD equipment to make system power supply to POE mains operated, thereby the POE power supplies with required electric quantity can for PD equipment, make the POE power supply have the practicality more.
Description
Technical field
This utility model relates to POE power supply technique field, is specially a kind of Intelligent Measurement POE power supply.
Background technology
POE technology can ensure the normal operation of existing network while guaranteeing existing structureization wiring safety, reduces cost to greatest extent.POE is also referred to as electric power system (POL based on LAN, Power over LAN) or active Ethernet (Active Ethernet), the most also POE it is called for short, this is to utilize transmission data and the newest standards specification of electrical power while existing standard Ethernet transmission cable, and maintains the compatibility with existing Ethernet system and user.One typical POE system.In distribution cabinet, retain Ethernet exchanging machine equipment, provide power supply to the twisted-pair feeder of LAN with a charged for electrical hub (Midspan HUB).At the end of twisted-pair feeder, this power supply is used for driving phone, WAP, camera and other equipment.For avoiding power-off, a UPS can be selected.
nullPOE powers and is more and more applied，But in actual use，When POE powers to PD equipment，Tend not to carry out intelligentized power supply according to practical situation，PSE switch cannot be found out and PD equipment is the most intact，Can power to PD equipment by force，Easily cause the damage of PD equipment，These are all the problems needing to solve，Need a kind of intelligentized POE power supply unit，Why it is intelligent power supply，Do not cry and power by force，They are to need communication and input suitable electric current，If POE module is broken，Switch can't detect，Electricity will not be given，If PES switch is broken，POE equipment Inspection less than and also cannot tell I higher level I need how many electricity，He would not work，Protect equipment the most completely，PD equipment simply detected，Allow PD equipment tell PSE switch I need electricity he just can power，So can improve the performance of POE equipment，Improve practicality.
Utility model content
The purpose of this utility model is to provide a kind of Intelligent Measurement POE power supply, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of Intelligent Measurement POE power supply, including system power supply, PSE switch and PD equipment, it is provided with DC/DC in described system power supply, PSE chip and POE power supply it is provided with in described PSE switch, it is provided with PD chip in described PD equipment, described system power supply is electrically connected at POE power supply, described POE power supply is electrically connected at PD equipment, described PD chip is connected with signal between DC/DC, described PSE chip is connected with PD inter-chip signals, and described PSE chip is connected with signal between POE power supply.
Preferably, described system power supply input is provided with civil power.
nullCompared with prior art，The beneficial effects of the utility model are: this utility model can realize intelligentized power supply，PD chip in PD equipment can learn that PSE switch is the most normal by the PSE chip from PSE switch，If normal PSE chip can give DC/DC signal in system power supply，DC/DC can learn the power consumption of PD equipment，So that system power supply is powered to POE power supply，Thus POE power supply supplies institute's subfam. Spiraeoideae can to PD equipment，Can be by PSE chip to POE power supply signal if PSE switch can not normally use，POE power supply powers to PD equipment，If thus PSE switch is broken，POE power detecting less than and also PD equipment subfam. Spiraeoideae cannot be learnt，He would not work，Protect equipment the most completely，Make power supply unit more intelligent，Will not power by force，POE is powered more there is practicality.
Accompanying drawing explanation
Fig. 1 is this utility model modular structure schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1, a kind of technical scheme of this utility model offer: a kind of Intelligent Measurement POE power supply, including system power supply, PSE switch and PD equipment, it is provided with DC/DC in described system power supply, PSE chip and POE power supply it is provided with in described PSE switch, it is provided with PD chip in described PD equipment, described system power supply is electrically connected at POE power supply, described POE power supply is electrically connected at PD equipment, described PD chip is connected with signal between DC/DC, described PSE chip is connected with PD inter-chip signals, and described PSE chip is connected with signal between POE power supply.Described system power supply input is provided with civil power.
Concrete, during use, civil power access system power supply, PD chip in PD equipment can learn that PSE switch is the most normal by the PSE chip from PSE switch, if normal PSE chip can give DC/DC signal in system power supply, DC/DC can learn the power consumption of PD equipment, so that system power supply is powered to POE power supply, thus POE power supply supplies institute's subfam. Spiraeoideae can to PD equipment, will not can be powered to PD equipment to POE power supply signal, POE power supply by PSE chip if PSE switch can not normally use.
nullThis utility model can realize intelligentized power supply，PD chip in PD equipment can learn that PSE switch is the most normal by the PSE chip from PSE switch，If normal PSE chip can give DC/DC signal in system power supply，DC/DC can learn the power consumption of PD equipment，So that system power supply is powered to POE power supply，Thus POE power supply supplies institute's subfam. Spiraeoideae can to PD equipment，Can be by PSE chip to POE power supply signal if PSE switch can not normally use，POE power supply powers to PD equipment，If thus PSE switch is broken，POE power detecting less than and also PD equipment subfam. Spiraeoideae cannot be learnt，He would not work，Protect equipment the most completely，Make power supply unit more intelligent，Will not power by force，POE is powered more there is practicality.
