Technical field

The invention belongs to smart electronics control technology fields, and in particular to a kind of POE power supply management circuit.

Background technique

As the construction process of human society to civilise constantly is accelerated, for public environment --- the environmental sanitation of lavatory It is also just getting faster with intelligence degree development, carries out wired networking/wireless networking based on various Data Detections or control display Intelligent lavatory application demand it is also increasing.

And in the network-control of traditional lavatory, in cable input and power supply power supply, all it is implemented separately, i.e. net Line only provides network information transmitting, and power supply power supply is independent line powered, realizes entire lavatory environment and internal multiple lavatory positions It is various and complicated that management and monitoring allows for route, and such circuit is excessive, control management is somewhat extra, can not effectively simplify power supply And control, it is unfavorable for optimum management.

Therefore, it is necessary to improve to traditional power supply mode.

Summary of the invention

The purpose of the present invention is to solve the above problems, provide a kind of POE power supply management circuit, are applied to intelligent lavatory On, mainly it is able to achieve effective power supply management.

In order to achieve the above object of the invention, the invention adopts the following technical scheme:

A kind of POE power supply management circuit, which is characterized in that export mould including POE local area network input module, POE local area network Block and POE power supply management module, the POE local area network input module, POE local area network output module are powered with the POE respectively Management module connection；

The POE local area network input module, POE local area network output module are for power supply and data transmission.POE local area network is defeated Enter module for data double-way and voltage input, POE local area network output module is transmitted for data double-way and voltage output.

The POE local area network input module or POE local area network output module use net mouth transformer.

The net mouth transformer uses H1102 model chip.

The POE power supply management module include metal-oxide-semiconductor Q7, metal-oxide-semiconductor Q8, resistance R61 and resistance R62, the metal-oxide-semiconductor Q7, Resistance R61, resistance R62 and metal-oxide-semiconductor Q7 are sequentially connected.

The metal-oxide-semiconductor Q7 uses 2N7002K-T1-GE3 using FDT434P_P_60V_2.5A model or the metal-oxide-semiconductor Q8.

The POE power supply management module further includes two patch rectifier circuits, and 2 feet of patch rectifier bridge, 1 are handed over to be connect respectively Voltage input end, voltage output end.

The POE power supply management module further includes the power supply circuit being formed by connecting by chip U14 and chip U13.

The patch rectifier circuit uses Bridge_MB2S_SO4 model.

It further include cable interface circuit, the cable interface circuit and the POE local area network input module, POE local area network Input module is separately connected.

The cable interface circuit uses RJ45/TOP_Tab/2 chip.

Compared with prior art, the present invention beneficial effect is: realizing cable using this circuit and directly power, utilize POE Local area network input module, POE local area network output module realize the unidirectional input of voltage, unidirectional output respectively, while realizing again The transmitted in both directions of data-signal, improves convenience to the control management of intelligent lavatory, simplifies the complexity of conventional management.
