Detailed description of the invention
Fig. 1 is the circuit theory schematic diagram of the design.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples:
Embodiment 1: a kind of signal indicating circuit of computer network testing, referring to Fig. 1.
It includes main circuit, specifically, the main circuit includes amplifier U, triode Y, light emitting diode D, load electricity
Hinder R；Wherein:
The normal phase input end of amplifier U is the input terminal of main circuit, the output end of amplifier U and the collector of triode Y
Connection；The collector of amplifier U connects a power supply VCC, and power supply VCC selects button cell；The emitter and hair of amplifier U
The input terminal of optical diode D connects.
Further, the output end of light emitting diode D is grounded by load resistance R, the reverse input end of the amplifier U
It is connected between the output end of light emitting diode D and load resistance R.
This signal indicating circuit further include: RJ45 connector, RJ45 socket, in which: lead between RJ45 connector and RJ45 socket
It crosses 8 radicals to connect according to lines matching, because having 8 data lines inside its current cable, therefore, between RJ45 connector and RJ45 socket
It is correspondingly connected with by 8 data lines；But in view of having the 4th (blue), 5 (blue and whites), 7 in 8 data lines inside cable
(palm fibre white), 8 (browns) are siding, in actual network test and do not use, therefore, RJ45 connector and RJ45 socket
Between can also be using the connection of four lines, at this point, four data lines are corresponding with the 1st, 2,3,6 line in cable respectively.
And if when between RJ45 connector and RJ45 socket by 8 data line connections；The main circuit at this time is eight,
Wherein the normal phase input end of eight amplifier U on eight main circuits is connect with one of data line respectively, similarly, and if
When between RJ45 connector and RJ45 socket by 4 data line connections；The main circuit at this time is four, wherein four main electricity
The normal phase input end of four amplifier U of road is connect with one of data line respectively.
In use, main circuit should be packaged in shell, and RJ45 connector and RJ45 socket respectively by for number
It is located at the left and right sides of shell according to line, in network test, the cable on when test host used is inserted into the design
In RJ45 socket, RJ45 connector is inserted into the equipment of test, and when network test, the signal transmitted in cable is simulation letter
Number, at this point, mould electric signal enters in amplifier U (operational amplifier) when there is network signal transmission, enter triode Y later
Collector promote triode Y be connected, hereafter, mould electric signal be amplified device U and triode Y amplification after promotes light emitting diode D
Shinny, by the shinny of light emitting diode D, current network connection known to real training personnel is normal.
By the design, it can be used in student network test training in use, can be carried out to positive by this circuit
The network signal of transmission is indicated that personnel prompt to real training, secondly, can more intuitive prompt reality by the design
Instruction personnel, while being also used as the apparatus of detection network data line, that is, whether network data line can detecte by the design
The case where whether there is single or more broken data wire inside connection, network data line, and when a certain in network data line
Or after more broken strings, its light emitting diode will not be bright in the data transmission for corresponding main circuit.
What the embodiments of the present invention were announced is preferred embodiment, and however, it is not limited to this, the common skill of this field
Art personnel understand the spirit of the utility model easily according to above-described embodiment, and make different amplification and variation, but as long as
