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.
nullRefer to Fig. 1，A kind of standard POE is integrated with forcing nonstandard POE by electricity power circuit，Including RJ45 interface、Metal-oxide-semiconductor Q1、Chip U5 and resistor-diode D2，The pin 11 of described RJ45 interface connects resistance R21，The other end of resistance R21 connects 3.3V voltage and resistance R19，The other end of resistance R19 connects the pin 13 of RJ45 interface，The pin 9 of RJ45 interface connects R16、Resistance R20、The foot 2 of P12 wire jumper and the source electrode of metal-oxide-semiconductor Q1，The other end of resistance R16 connects resistance R14、Electric fuse F1、The foot 1 of electric capacity C20 and chip U5，The other end of electric fuse F1 connects the pin 10 of RJ45 interface，The other end of resistance R14 connects the negative electrode of diode D2，The anode of diode D2 connects the other end and the grid of metal-oxide-semiconductor Q1 of resistance R20，The drain electrode of metal-oxide-semiconductor Q1 connects the other end of electric capacity C20、The anode of diode D1、Electric capacity C22、The foot 3 of chip U1、The foot 3 of the foot 5 and P12 wire jumper of chip U1，The foot 2 of chip U1 connects the negative electrode of diode D1、The other end of electric capacity C22、The foot 4 of chip U1 and output voltage，The model of described RJ45 interface is hy931147c，The model of chip U5 is LM2596HVT-5.
The model of metal-oxide-semiconductor Q1 is CSIN60.The model of P12 wire jumper is JP-3P.
Operation principle of the present utility model is: 1, under the standard of the exchanger POE agreement powering mode: P12 wire jumper not short circuit, as shown above, after POE switch detects the 24.9k resistance of network transformer rear end R16, can sound out and be powered, when reaching 27V, D2 turns on, and Q1 turns on, power supply is powered to U5, U5 can by the 48V-55 power supply of POE switch through DC-DC convert after export to after level work.
2, under nonstandard pressure POE powering mode: P12 only need to be by jump cap short circuit 1,2 foot.The 7-60V power supply that front end is transmitted through by netting twine is directly powered to U5 by the conducting of P12 jump cap, U5 after DC-DC blood pressure lowering for rear class equipment.
3, whole circuit make use of switching characteristic and the short circuit power supply mode of Q1 dexterously, it is achieved that single circuit compatibility standard POE agreement simultaneously is powered and forces non-standard POE powering mode.The most only need to develop product always and can support two kinds of power supply modes simultaneously.
4, design has foolproof function simultaneously, in the case of P12 short circuit 1,2 foot (nonstandard power taking pattern), if equipment is accessed standard POE switch by user by mistake, owing to switch detection circuit capacitance-resistance value is much larger than POE consensus standard, therefore POE switch will not be powered.In like manner at P1,2 not (standard power taking pattern) in the case of short circuit, if equipment is accessed in constrained feed netting twine by user by mistake, equipment does not turns on work under less than 27V voltage, and during 27V-60V, Q1 turns on, and equipment normally works.Therefore, in the range of nominal tension, no matter accessing the switch of which kind of powering mode, this circuit all will not damage.In like manner, in the course of the work, if user changes P12, jumping emits short circuit mode to circuit, also will not damage circuit.
