The control unit comprises a central processing unit (CPU) controller, a display and a keyboard which is electrically connected with a communication interface of the CPU controller. A control interface of the CPU controller is electrically connected with the input end of a multipath output analogue switch and the output end of a multipath input analogue switch. The plurality of output ends of the multipath output analogue switch are connected with the plurality of input ends of the multipath input analogue switch in a one-to-one correspondence way, and then is electrically connected with the wiring end of a first network interface respectively. The output end of the multipath input analogue switch is electrically connected with the signal input end of the CPU controller by a signal conditioning module and an A/D signal conversion module. The terminal matching unit comprises a second network interface. Each wiring end of the second network interface is electrically connected with a resistor. The other ends of each resistor are electrically connected with one another. The device has the advantage of intuitively, conveniently and rapidly testing the network cable connection diagram distributed in a building.
Description
Technical field
The present invention relates to the Ethernet winding diagram, especially relate to the testing apparatus for Ethernet netting twine winding diagram.
Background technology
Along with the progress of development of science and technology and society, the intelligent building system has obtained fast development.Quick growth along with intelligent building quantity has also brought challenge to network comprehensive lining.In the time of intelligent building construction and decoration at present, need carry out network layout in advance usually, if carry out RJ45 interface (network interface) crimping earlier this moment, then cause the inconvenience in the time of wiring, poling easily; Otherwise, if do not carry out the crimping of RJ45 interface in advance, so after wiring during crimping RJ45 interface, the experience that then mainly relies on the operator, and owing to the RJ45 interface generally is not in the same localities, if adopt easy grid line order tester, then need to observe simultaneously the bright lamp situation of transmitting terminal and receiving terminal to judge whether wiring is correct, therefore can't carry out the test of line order in this case, be merely able to match according to the cable color, what this caused easily again that cable wiring correctness do not have a science directly perceived declares the formula foundation.
Summary of the invention
The object of the invention is to provide a kind of testing apparatus for Ethernet netting twine winding diagram, and is directly perceived, convenient to realize, detect the correctness of Ethernet cable wiring rapidly.
For achieving the above object, the present invention can take following technical proposals:
Testing apparatus for Ethernet netting twine winding diagram of the present invention, it comprises control unit, terminal matching unit; Described control unit comprises cpu controller, is electrically connected on the display of described cpu controller output interface and the keyboard of communication interface; The control interface of cpu controller is electrically connected with the input of multichannel output analog switch, the output of multichannel input analog switch respectively; After connecting one to one, a plurality of inputs that a plurality of outputs of described multichannel output analog switch and described multichannel are imported analog switch are electrically connected with terminals of first network interface respectively; The output of multichannel input analog switch is electrically connected with the signal input part of cpu controller through signal condition module, A/D signal conversion module; Between the input of the output of multichannel input analog switch and signal condition module, be electrically connected with sampling resistor, the other end ground connection of described sampling resistor; Described terminal matching unit comprises second network interface, is electrically connected with a resistance respectively at each terminals of described second network interface, and described each resistance other end is electrically connected mutually.
Described first, second network interface is the RJ45 network interface of eight heart yearns; The resistance that is electrically connected on eight terminals of second network interface is respectively R1=10 kilo-ohm, R2=20 kilo-ohm, R3=30 kilo-ohm, R4=40 kilo-ohm, R5=50 kilo-ohm, R6=60 kilo-ohm, R7=70 kilo-ohm, R8=80 kilo-ohm; Described multichannel output analog switch is one the tunnel to import eight tunnel outputs; Described multichannel input analog switch is eight the tunnel to import one tunnel output; Described sampling resistor R9=100 kilo-ohm.
The invention has the advantages that realization is directly perceived, convenient, rapidly the netting twine winding diagram that cloth is good in building tested, avoided with netting twine from cable duct, take out carry out loopback test with judge network connection figure whether correct after the process of cabling again again, alleviate unnecessary work greatly, improved testing efficiency and the accuracy of netting twine.During test, respectively with described first, second network interface is electrically connected with the network interface at netting twine to be tested 3 two ends that cloth is good, the terminal matching unit constitutes the star resistor network by eight resistance, control multichannel output analog switch and multichannel input analog switch switches by described cpu controller, make in described signal power source and the terminal matching unit each resistance in turn with control unit in sampling resistor constitute series circuit, thereby the output at multichannel input analog switch obtains one group of sampled voltage, and with described sampled voltage through the signal condition module, the A/D signal conversion module feeds back to cpu controller.When open circuit conditions appearred in some cables of netting twine 3 to be tested, the magnitude of voltage that A/D collects approached zero volt, and LCD was in graphics mode demonstration netting twine 3 certain root cable and opened circuit this moment.When short-circuit conditions appearred in some cables of test netting twine 3, the full scale situation can appear twice in the A/D Acquisition Circuit; This moment, LCD showed this two cable short circuits with graphics mode, if cable occurs opening circuit or short-circuit conditions, it is meaningless then to measure winding diagram this moment.When cable is not to open circuit or short circuit, then can judge the situation that is connected of the first network interface cable with the second network interface cable of tested cable 3 according to maximum, the minimum value of A/D sample voltage value, and on LCD, show with graphics mode.
