Background technology
Currently, traditional POE interchangers are made of exchange chip, network transformer, POE network interfaces and power supply module, for
Each POE network interfaces cannot play network interface managerial role.We have developed a kind of intelligent POE interchangers thus, to solve network interface
Intelligent management problem.
Invention content
Whether one kind is provided the invention aims to overcome the deficiencies in the prior art can determine whether upstream device by recognizing
Card, can control signal and the intelligent POE interchangers for electrical connection.
In order to achieve the above objectives, the technical solution adopted by the present invention is：A kind of intelligent POE interchangers, including management net
Mouth, network transformer, MCU, exchange chip, relay, power supply module, POE network interfaces, it is characterised in that：Upstream remote management master
Machine is powered through the network transformer to the MCU by the management network port, and the MCU turns off the relay by GPIO
Device connect to physically disconnect with the network signal of POE network interfaces described in any one or all；The exchange chip can lead to
It crosses network signal data and judges either all whether the equipment of the POE network interfaces is in certification or the shape that reasonably works for some
State；Whether the MCU gives POE equipment power supply by power supply module described in I2C bus marcos.
Preferably, the management network port can notify the MCU to disconnect any one or all confession of the POE network interfaces
Electricity.
Preferably, the exchange chip can judge any one by network data or all the POE network interfaces are set
Standby whether to be in certification or rational working condition, once there is illegal operation, the exchange chip is notified by I2C interface
The MCU after the MCU is judged, controls whether to disconnect the relay and POE network interfaces power supply.
Preferably, the POE network interfaces are at least 4.
Due to the application of the above technical scheme, the present invention has following advantages compared with prior art：
Intelligent POE interchangers of the present invention, are to provide one kind for overcome the deficiencies in the prior art and can determine whether
Whether upstream device passes through certification, can control signal and for electrical connection.
Description of the drawings
Technical scheme of the present invention is further explained below in conjunction with the accompanying drawings：
Attached drawing 1 is the circuit diagram of intelligent POE interchangers of the present invention；
Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment, the present invention is described in further details.
Attached drawing 1 be intelligent POE interchangers of the present invention circuit diagram, including management network port 1, network transformer 2,
MCU3, power supply module 4, exchange chip 5, relay 6 and POE network interfaces 11.Upstream remote managing main frame passes through the management network port
It is communicated to the MCU3.The MCU3 is communicated by I2C buses with the power supply module 4 and the exchange chip 5；The MCU3
The break-make of the relay 6, relay 7, relay 8, relay 9 is controlled by GPIO；The MCU3 passes through I2C bus marcos
Whether the power supply module 4 is to the POE network interfaces 11, POE network interfaces 12, POE network interfaces 13, the power supply of 14 equipment of POE network interfaces；Network becomes
Depressor 10 is powered to the relay 6, relay 7, relay 8, relay 9.
In the present embodiment, upstream remote managing main frame can notify the MCU3 by the management network port 1, shutdown it is described after
Electric appliance 6, relay 7, relay 8, relay 9, to physically disconnect with any one or all described POE network interface 11,
The signal connection of POE network interfaces 12, POE network interfaces 13, POE network interfaces 14；
The exchange chip can be judged by network data some or all the POE network interfaces 11, POE network interfaces 12,
POE network interfaces 13, POE network interfaces 14 equipment whether be in certification or rational working condition, once there is illegal operation, it is described
After exchange chip 5 notifies the MCU3, the MCU3 to judge by I2C interface, control whether to disconnect the relay 6,
Relay 7, relay 8, the break-make of relay 9 and the POE network interfaces 11, POE network interfaces 12, POE network interfaces 13, POE network interfaces 14
Power supply.
Upstream remote managing main frame is thinking the legal and period that is authenticating, is notified by the management network port 1 described
MCU3 opens the relay 6, relay 7, relay 8, relay 9 by GPIO, opens whole POE network interfaces 11, POE nets
The signal connection of mouth 12, POE network interfaces 13, POE network interfaces 14.The power supply module 4 is controlled to being connected on the POE by I2C interface
The equipment power supply of network interface 11, POE network interfaces 12, POE network interfaces 13, POE network interfaces 14.
After upstream device is connected to the POE network interfaces 11, POE network interfaces 12, POE network interfaces 13, POE network interfaces 14, believed by network
Number timing sends out the data packet authenticated to the exchange chip 5；
The exchange chip 5 receives on POE network interfaces 11, POE network interfaces 12, POE network interfaces 13, POE network interfaces 14 described in downstream
Whether the data of equipment, verify data are legal.Authentication data is not such as received or data are improper, then is reported to the MCU3,
Notice is abnormal；
The MCU3 is connected to abnormal notice, then turns off the relay 6, relay 7, relay 8, relay 9 and described
POE network interfaces 11, POE network interfaces 12, POE network interfaces 13, POE network interfaces 14 power, and are reported to remote management by the management network port 1
Host；It can determine whether upstream device passes through certification to provide one kind, can control signal and for electrical connection.
The POE network interfaces quantity is at least 4, is configured according to management network port 1 and exchange chip 5, and the POE network interfaces can be with
It is 4,8 or 16.Usual 4 network interfaces are applied in 100 m ethernet, and 8 network interfaces are applied powers in gigabit Ethernet POE
On device, the power of the more consumption of network interface is bigger.
