Wherein on two cores.
The present invention is further improved by: feeder ear equipment PSE interface is Ethernet switch or POE mould
The interface of block, receiving end equipment PD interface is Ethernet video camera or the interface of Ethernet AP.
The present invention is further improved by: switching as double-pole single throw, each switch can control lattice chain simultaneously
One core on road and the break-make of corresponding display lamp.
The present invention is further improved by: display lamp has eight, and with eight core grid line one_to_one corresponding, display lamp uses straight
Stream power supply is individually powered.
The present invention is further improved by: voltmeter has four, and the measurement of four voltmeters is rectified negative pole and connect net respectively
The 1 of winding thread and 3,2 and 6,4 and 7,5 and 8 cores.
The present invention is further improved by: four-wire system voltmeter selected by voltmeter, and its power supply circuits divide with measuring circuit
From.
The present invention is further improved by: when test, network twisted-pair cable is first connected to feeder ear equipment PSE and connects
Mouthful, closing 8 way switch, observe the reading of four voltmeters, two of which voltmeter reading is 0, and another two voltmeter reading is
In 10V, unstable numerical value, shows that feeder ear can carry out POE, and has sent detection voltage.
Compared with prior art, present invention have the advantage that:
1, to be realized with a low cost the checking of POE principle；
2, can accurately measure out the voltage that POE powers, do not affect the transmission of network data simultaneously；
3, the duty of eight core grid lines in network link can intuitively be demonstrated by display lamp；
4, by on-off control, can verify, under two kinds of different POE power supply modes, how eight core grid lines are further
Carry out the transmission of network signal and power supply signal.
Accompanying drawing illustrates:
Fig. 1 is the electrical block diagram of a kind of POE of present invention test device；
In figure: 1, feeder ear equipment PSE interface；2, receiving end equipment PD interface；3, display lamp；4, switch；5, voltmeter；
6, DC source；7, network twisted-pair cable.
Detailed description of the invention:
The invention will be further described with embodiment below in conjunction with the accompanying drawings:
See Fig. 1, a kind of POE test device, including feeder ear equipment interface 1, receiving end equipment interface 2, refer to
Show lamp 3, switch 4, voltmeter 5, DC source 6 and network twisted-pair cable 7；Wherein, feeder ear equipment interface 1 connects with receiving end equipment
Mouth 2 is connected by network twisted-pair cable 7, and feeder ear equipment interface 1 provides net by network twisted-pair cable 7 for receiving end equipment interface 2
Network signal and the signal of telecommunication.
Display lamp 3 is eight, does not use POE mode, is individually powered by DC source 6, with network twisted-pair cable
The eight core one_to_one corresponding of 7.
On each core of network twisted-pair cable 7, be respectively connected in series into a double-pole single throw, double-pole single throw respectively in order to
Control netting twine and the break-make of display lamp.The break-make of eight road network lines can be intuitively shown by eight display lamps 3.
Voltmeter 5 has four, the both positive and negative polarity of four voltmeters 5 connect respectively 1 and 3,2 and 6,4 and 7 of network twisted-pair cable 7,5
With 8 cores.In order to improve stability, four-wire system voltmeter selected by voltmeter 5, and power supply circuits separate with measuring circuit.
When reality is tested, first network twisted-pair cable 7 is connected to feeder ear equipment PSE interface 1, closes eight way switch 3, see
Examining the reading of four voltmeters 5, two of which meter reading is 0, and another two meter reading is the unstable magnitude of voltage of below 10V, shows
Feeder ear equipment interface 1 can carry out POE, and has sent detection voltage.Again network twisted-pair cable 7 other end is connected to
Receiving end equipment PD interface 2, voltmeter 5 reading is changed to the burning voltage of about 50V, shows receiving end normal power supply work
Make.
If voltage is that between zero, 4 and 7,5 and 8 lines pair, voltage is not zero between network twisted-pair cable 1 and 3,2 and 6 line pair, then illustrate
