The POE technology that mainly use the repeater of present employing transparent transmission WLAN mode is: the access unit of many network distribution systems and capping unit are realized POE, external switch and AP realize POE, two overlap independently the POE system, and POE closes the road and distribution module realizes same category-5 cable power supply by adding at access unit and capping unit, as shown in Figure 3.But the realization prerequisite of this technology is the switch of wlan system must support the POE function, and two overlap the increase that the POE systems will certainly bring system cost.In addition, present POE technology is mainly with 1/2﹠amp; 3/6 or 4/5﹠amp; The power supply of 7/8 core, other core the transmission of data.And two cover POE power supplies completely of this technology, and the power supply core of repeater can not conflict with the POE power supply for exchange.Compare with the POE technology of standard for electrical transmission completely, can bring Electro Magnetic Compatibility and stability problem.
Summary of the invention
The utility model is exactly for the problems referred to above, and a kind of Electro Magnetic Compatibility and good stability are provided, and cost low based on many network distributions of category-5 cable POE electric power system.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises access unit and capping unit, access unit links to each other by category-5 cable with capping unit, its structural feature access unit comprises access signal processing module, PSE(Power Sourcing Equipment feeder ear equipment) module and many signals close the road module, capping unit comprises that filter module, POE distribution module, WLAN close road module, PD(Powered Device feeder ear equipment) module and cover signal processing module.
Described many signals close the road module port and link to each other with access signal processing module port, PSE module port, filter module port, switch ports themselves respectively, and access signal processing module port links to each other with information source.
Described POE distribution module port closes the road module port with filter module port, WLAN respectively, the PD module port links to each other, the filter module port closes the road module port with WLAN respectively, covering signal processing module port links to each other, PD module, covering signal processing module port, antenna link to each other successively, and WLAN closes the road module port and links to each other with the AP of built-in PD module.
As a kind of preferred version, information source described in the utility model is 2G and/or 3G information source.
As another kind of preferred version, PSE module described in the utility model adopts TPS23851 PSE chip.
Secondly, POE distribution module described in the utility model adopts TPS2376DDA PD chip.
In addition, PD module described in the utility model adopts TPS23753A PD chip.
The utility model beneficial effect.
Access unit of the present utility model adopts the PSE module, and capping unit adopts the POE distribution module, has realized capping unit and AP power supply, and namely PSE one port is powered to many PD.Therefore, the utility model switch needn't possess the POE function, and cost is low; And Electro Magnetic Compatibility and good stability.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described further.The utility model protection range not only is confined to the statement of following content.
Fig. 1 is that the utility model is used block diagram.
Fig. 2 is the utility model theory diagram.
Fig. 3 is that existing many network distributions of category-5 cable POE electric power system is used block diagram.
Embodiment
As shown in the figure, the utility model comprises access unit and capping unit, access unit links to each other by category-5 cable with capping unit, access unit comprises that access signal processing module, PSE module and many signals close the road module, and capping unit comprises that filter module, POE distribution module, WLAN close road module, PD module and cover signal processing module.
Described many signals close the road module port and link to each other with signal processing module port, PSE module port, filter module port, switch ports themselves respectively, and access signal processing module port links to each other with information source.
Described POE distribution module port closes the road module port with filter module port, WLAN respectively, the PD module port links to each other, the filter module port closes the road module port with WLAN respectively, covering signal processing module port links to each other, PD module, covering signal processing module port, antenna link to each other successively, and WLAN closes the road module port and links to each other with the AP of built-in PD module.
Described information source is 2G and/or 3G information source.
Described PSE module adopts TPS23851 PSE chip.
Described POE distribution module adopts TPS2376DDA PD chip.
Described PD module adopts TPS23753A PD chip.
Below in conjunction with the description of drawings course of work of the present utility model.
The PSE module access-48V power supply of access unit closes the road module by many signals, with the 1/2﹠amp of category-5 cable; 3/6 independent transmitting WLAN signal, 4/5﹠amp; 7/8 transmission movable signal and POE signal.
The POE function of system is realized by the PSE chip of access unit and the PD chip of capping unit POE distribution module.Because the not integrated DC-DC circuit of PD chip TPS2376DDA of POE distribution module, so the TPS2376DDA output voltage be+power supply signal of 48V and-48V; Export respectively this power supply signal to the PD module and WLAN closes the road module, can power to corresponding module.This moment since the PSE module set up by standard P OE with the PD chip of POE distribution module and be connected, so the PD module of capping unit and AP is only as power receiving equipment at this moment, the PD chip TPS23753A of PD module is integrated DC-DC circuit, output voltage is the module required voltage, can work.Capping unit and AP are equivalent to the load of POE distribution module; when equipment occurs when unusual, the PSE module can be controlled the PD chip of POE distribution module, realizes defencive function; thereby realized POE power supply and the corresponding power protection mechanism of many equipment, evaded again the weak point of existing scheme.
