This central control module is used for giving a plurality of power device the power supply simultaneously to it gives a plurality of power device to provide control signal.
Description
Technical field
Embodiment of the present utility model relates to PoE (PoweroverEthernet) technology, particularly relates to the central control module of a kind of PoE.
Background technology
PoE refers to when existing Ethernet Cat5 wiring architecture does not make any changes, while for some IP-based terminals (as IP telephone machine, wireless local network connecting point AP, web camera etc.) transmission of data signals, the technology of direct current supply can also be provided by kind equipment for this reason.PoE technology can ensure the normal operation of existing network while guaranteeing existing structureization wiring safety, reduces costs to greatest extent.
Along with the fast development of LED illumination, make based on PoE intelligent lighting solution more and more for practice in.Fig. 1 shows the existing lighting solutions based on PoE, comprising server, and router, PoE switch and PoE light fixture.Wherein PoE light fixture comprises four parts: LED light source, LED driver, control unit and PD (PowerDevice, power receiving equipment) interface.PoE light fixture is connected with the port of PoE switch by RJ45 joint and Cat5 netting twine.
The shortcoming of this solution is, each PoE light fixture needs an independently control unit, and Cat5 netting twine between light fixture and switch ports themselves is very long.This causes the cost increase of this solution.In addition RJ45 interface is not also in the scope of the 3C certification of illuminating product, and this causes the 3C certification of this PoE light fixture to go wrong.
Utility model content
In view of the defect that above-mentioned prior art exists, one of object of embodiment of the present utility model is to provide the central control module of a kind of PoE, comprises multiple PD interface module and a control unit.This central control module is used for powering to multiple power receiving equipment simultaneously, and provides control signal to multiple power receiving equipment.
In an embodiment of the present utility model, each PD interface module of central control module is connected to a port of PoE switch or PoE router, such as, by Cat5 netting twine and RJ45 joint.
In another embodiment of the present utility model, this central control module is used for powering for multiple power receiving equipment, and provides control signal for power receiving equipment.Control unit comprises multiple current supply circuit, and wherein each current supply circuit is used for being supplied to a power receiving equipment from by the power supply of a PD interface.Control unit also comprises a controller and an Ethernet filter.Ethernet filter is used for being used for extracting in the ethernet signal exported from PD interface the control signal controlling power receiving equipment.
This power receiving equipment is such as lighting apparatus, as LED illumination device.Control signal as PWM dim signal, 0-10V or 1-10V voltage dim signal, or simply open and OFF signal etc.
Usual LED illumination device can by DC power drives, and therefore in an embodiment of the present utility model, the output direct current of PD interface can be powered directly to LED illumination device, and without the need to changing through AC-DC.
In an embodiment of the present utility model, PoE central control module is connected to the equipment of its power supply by common wiring, such as LED illumination device.Common wiring as the red-black power line that is connected with light source of driver, concrete wire diameter can be determined according to the size of power.
The PoE central control module that embodiment of the present utility model adopts, provides cost savings, solves the 3C authentication question of lighting apparatus.

Embodiment
Below with reference to exemplary embodiment, principle of the present utility model and spirit are described.Should be appreciated that describing these embodiments is only used to enable those skilled in the art understand better and then realize the utility model, and not limit scope of the present utility model by any way.
Fig. 2 is the lighting solutions schematic diagram of the PoE central control module 20 according to an exemplary embodiment of the present utility model.
As shown in Figure 2, central control module 20 comprises multiple PD interface 21 and a control unit 22.Server 11, by router one 2 and PoE switch 13, controls LED illumination device 14 via central control module 20.
With shown in Fig. 1 unlike comparatively simple in, multiple LED illumination device 14 structure comparatively Fig. 1, only comprise LED driver and LED light source.Multiple such LED illumination device 14 carries out Power supply and control by a concentrated central control module 20.Each PD interface 21 of central control module 20 is connected with the port of Cat5 netting twine with PoE switch by RJ45 joint.Central control module 20 can be placed on from the place close to PoE switch 13, to shorten the length of Cat5 netting twine, thus saves cost.
Control unit 22 in Fig. 2 is integrated with the function of the multiple control units in Fig. 1, thus saves hardware cost.
Central control module 20 is connected to LED illumination device 14 by common power line and joint, thus solves the 3C authentication question of lighting apparatus.
Fig. 3 shows the structural representation of the central control module 20 according to an embodiment of the present utility model.Wherein, the detailed construction schematic diagram of control unit 22 is shown.
Control unit 22 comprises a microcontroller 221, Ethernet filter 222, and the DC current supply circuit 223 connecting often pair of PD interface and LED lamp, this DC current supply circuit 223 comprises a power switch 224, power switch can be MOSFET, and common power triode is as BJT etc.
Central control module 20 receives from host computer (as the server 11 in Fig. 2, or unshowned equipment in other Fig. 2) the control signal encapsulated with the form of Ethernet protocol, this control signal arrives certain PD interface, rightmost as shown in Figure 3 PD interface 21, Ethernet filter 222 extracts control signal from Ethernet encapsulated signal.This control signal is loaded on each power switch 224, thus realizes the control to each LED illumination device.Control signal is such as switching signal, PWM dim signal, 0-10V or 1-10V voltage dim signal etc.
The power stage of PD interface is supplied to LED lamp by DC current supply circuit 223, and it realizes the control of the power supply to LED lamp by a power switch 224.
