Abstract

The utility model relates to an information network test device, in particular to a device which can conduct automatic tests for the ADSL network. The utility model comprises a computer, a controlling software, an electronic matrix, a test unit, a USB converter module, and other units; wherein, an end of the test cable is connected with the output port of the electronic matrix, and the other end is connected with the distribution frame; the circuit input port of the electronic matrix is connected with the test wire of the test unit, the controlling port of the electronic matrix is connected with the output end of the USB converter module, and the input end of the USB converter module is connected with the output port of the computer. The utility model can be conveniently plugged in when the subscriber is testing. When testing, the circuit positioned at a side of the switcher can be cut off, and the test of the high frequent circuit is achieved; when not testing, the normal using of the subscriber is not affected; the interference between a plurality of lines and a line can be measured at one time, and the single-end testing, the lot-quantity testing and the timing testing can be attained; after testing, the reason and the position for failure can be analyzed; so that the device can be used by persons without specialty knowledge.

Description

Adopt the automatic grab wire testing device of adsl line of electronic matrix

Technical field:

The utility model relates to the information network testing apparatus, especially the device that the ADSL network is tested automatically.

Background technology:

At present domestic adsl line test major part is to rely on universal instrument, 112 systems and handheld instrument, need two people to cooperate and carry out Dual-Ended Loop Test, test event is few, efficient is low, can not carry out diagnostic analysis and fault is qualitative, the location to test result, and can not carry out single-ended batch and fixed time test adsl line.And test result can not be preserved and inquire about easily.When user applies ADSL is professional, be to guarantee user's development, often circuit is not tested open-mindedly immediately, as run into the subscriber's line poor quality, can not carry ADSL when professional, cause that the user is discontented, it is passive that service causes.Along with increasing rapidly of customer volume, operation maintenance work is doubled and redoubled, and relies on the Dual-Ended Loop Test method of service mode and handheld instrument after traditional fault can not adapt to the needs of business development far away.

This purpose is: a kind of automatic grab wire testing device of adsl line that adopts electronic matrix is provided.

Summary of the invention:

It is made up of computer, Control Software, electronic matrix, test cell, USB modular converter etc.; Test cable one end connects the electronic matrix output port, and the other end connects distributing frame; The circuit input port of electronic matrix connects the p-wire of test cell, and the control port of electronic matrix connects USB modular converter output, and USB modular converter input connects the fanout mouth.

Are Control Software adopts following steps to finish: the test → initialization test equipment of a circuit of beginning → the be provided with corresponding relation of measurement circuit and electronic matrix, the circuit that selection will be tested → control electronic matrix grabbed line → transmission test command → reception return information → receive? be not! → return; Be! → handle test result → whether all test finishes? be not! Return; Be! → control electronic matrix carries out the test of unwrapping wire → circuit of end.

The beneficial effects of the utility model are, can be very convenient insert during user test, and can indicate contact condition when inserting; During test, can cut off the circuit of exchanger side, finish the line test of high frequency, when after access, not testing again simultaneously, not influence user's normal use.Once can measure crosstalking between many circuits and the circuit, realize single end testing, batch testing, fixed time test,, analyze out of order reason and position immediately after test is finished simultaneously by analysis to test result.Make the personnel that do not have professional knowledge, also can use this device.

Description of drawings:

Accompanying drawing 1 is an electrical connection graph of the present utility model;

Accompanying drawing 2 is system block diagrams of the present utility model;

Accompanying drawing 3 is software flow patterns of the present utility model.

Execution mode:

It is made up of computer, Control Software, electronic matrix, test cell, USB modular converter etc.; Test cable one end connects the electronic matrix output port, and the other end connects distributing frame; The p-wire of the circuit input port of electronic matrix (Analyzer mouth) connection test cell (TIP, RING), the control port of electronic matrix connects USB modular converter output, and USB modular converter input end connects the fanout mouth.

Among the figure: 1: be the test cell control cable; 2:USB changes serial port module: 3: the electronic matrix control cable; 4: the electronic matrix port connects the connecting line of test cell TIP, RING; 5: the test cell earth terminal; 6: the test line when crosstalking test; 7: test cell 18VDC; 8: the electronic matrix AC Power supply socket; 9: measurement circuit outside line gang socket; 10: the gang socket of measurement circuit interior lines.

The electronic matrix equipment of high frequency characteristics is satisfied in employing, during test, by the circuit of software control electronic matrix cut-out exchanger side, finishes the line test of high frequency.When after access, not testing again simultaneously, do not influence user's normal use.By the use of electronic matrix and the control of software, circuit is carried out batch testing, and (according to the test event difference, the time is 1-3 minute) influences the user of this circuit when having only a certain circuit of test, back recovery is automatically finished in test.By the connection of this device, can also many circuits of one-shot measurement and a certain circuit between crosstalk.Owing to there are two serial ports control lines, this device has adopted USB to change Serial Port Line, makes the control computer can be desk-top and notebook computer (having only a serial ports at most).In order not influence the user as far as possible,, can make system midnight, regularly start batch testing by the fixed time test function of software.

Adopt the MDF mode that inserts in upright arrangement at measuring chamber, write down telephone number or the MDF position of measuring in upright arrangement and carry out single end testing by the testing software on the notebook, after test was finished, the testing software on the notebook drew test result, also can check the graph curve of test.
