Description
Technical field
The present invention relates to a kind ofly in stranding operation engineering, be used for detecting polycore cable and the method that twisted pair wire broken string or dislocation continue whether occurs.
Technical field
The telecommunication cable circuit is uniform transmission line, when cable line generation obstacle, can cause impedance not match, and according to the transmission theory of electromagnetic wave in transmission line, electromagnetic wave can produce reflection at barrier point; When the broken string obstacle appearred in circuit, reflected impulse was the positive polarity direction; And when the short circuit obstacle appearred in circuit, reflected impulse was the negative pole direction.By perception reflex arteries and veins polarity, just can judge obstacle character, shown in Figure 1.The break-make method of test cable lead: the lead of cable one end is connected together all, and the lead-in wire of multimeter or pilot lamp one end is linked to each other with this section, the lead-in wire other end connects every lead of the cable other end one by one.Disconnection fault is exactly the cable core open circuit.
And in the stranding process, pair split might take place, thereby produce underproof semi-manufacture.If semi-manufacture are untimely to be reprocessed, and enter next procedure, after finished product puts goods on the market, will bring a lot of drawbacks.Therefore, before cable dispatched from the factory, the quality of production of tackling each link was carried out strictness control, and the application just is being based on above-mentioned background and the design carried out.
Summary of the invention
The object of the invention provides a kind of detection streamer line of can in time finding thereby the dislocation that whether occurs continuing is prevented that defective semi-manufacture from flowing into the detection method of next procedure.
In order to achieve the above object, the technical solution adopted in the present invention is: a kind of polycore cable dislocation detection method that continues, and described polycore cable comprises a plurality of twisted pair wires, this detection method comprises the steps:
(1), each twisted pair wire is separated respectively and coiled two bundles at the two ends of cable;
(2), extract wherein any single line in pricking of cable one end, and this single line is linked to each other the other end of this test circuit formation loop that links to each other with other all single lines of this bundle with a test circuit;
(3), if test circuit has signal output, then this root single line continues well; If the output of test circuit no signal, then this root single line is misplaced;
(4), extract cable one end another prick in any single line, equally by the test circuit formation loop that links to each other with other all single lines of this bundle; The result judges as step (3).
Described test circuit is formed by pilot lamp and with the power supply that pilot lamp is electrically connected, the power supply composition that also can adopt hummer and be electrically connected with hummer.
Step (2) is or/and in the step (4), the replaceable bundle for the line corresponding with the cable other end of the other end of test circuit is connected to form the loop.
It also comprises the burn out detection step, described burn out detection step carry out step (1) before or step (4) afterwards, it comprises the steps:
(a), a plurality of twisted pair wires with cable one end separate and coiled two bundles;
(b), extract a twisted pair wire arbitrarily out, utilize other single line of described test circuit one termination this end, the other end is connected respectively with this twisted pair wire, and as if all there being signal to export, then this twisted pair wire breaks at the other end of cable; If no signal output, broken string appears in then relative single line.
Because adopt technique scheme, the present invention has the following advantages: adopt detection method of the present invention can quick and easyly prevent the cable pair problem of misalignment effectively, for the quality of production that guarantees cable lays the foundation.

Accompanying drawing 1 is cable view and oscillogram when broken string and mix line fault occurring;
Accompanying drawing 2 carries out the cable dislocation detection synoptic diagram that continues for the present invention;
Accompanying drawing 3 is the circuit theory diagrams shown in the accompanying drawing 2;
Accompanying drawing 4 carries out cable break fault detect synoptic diagram for the present invention;
Accompanying drawing 5 is accompanying drawing 4 described circuit theory diagrams.
Embodiment
Below in conjunction with accompanying drawing, the preferred specific embodiment of the present invention is described:
As shown in Figures 2 and 3 the cable dislocation detection method that continues, it comprises the steps:
At first, with line to or all twisted pair wires of an end of cable core separately, and carry out separately becoming A line and B line around bundle; Online to or the other end of cable also separately with all twisted pair wires, equally around being bundled into A line and B line; Usually, the A line is a ground wire, and it is with deceiving colour code; The B line is the signal wire of different colours, so can easily it be separated;
Then, any single line in the wherein bundle of extraction cable one end, and this single line linked to each other with a test circuit, the other end of this test circuit links to each other with other all single lines of this bundle and constitutes the loop, particularly, extract a single line out as any from left end A line shown in Figure 3, or from left end B line, extract a single line arbitrarily out, between single line of extracting out and pairing line bundle, be connected to form the loop by a pilot lamp and power supply;
Like this, if pilot lamp is bright, represent that then this root single line continues well; If pilot lamp does not work, then the fault that continues that misplaces appears in this root single line;
Accompanying drawing 3 is circuit theory diagrams, has provided the two states good and that dislocation continues that continues among the figure, in the manner described above other single line is detected, and can determine whether to occur the fault that continues that misplaces one by one.
In the above-mentioned detection, also can prick the formation loop that links to each other at the arbitrary single line that cable one end extracts by the test circuit line corresponding with the cable other end, if extract a single line of left end A line, test circuit one end is connected with this single line, and the other end is pricked with the A line of right-hand member and is connected.After constituting the loop, the judgement of still adopting above-mentioned mode whether to misplace.
Misplace continue judge before or after the judgement, also can carry out burn out detection, detection method as shown in Figure 4 and Figure 5, it comprises the steps:
At first, with a plurality of twisted pair wires of cable one end separately and coiled two prick, be made as A line and B line equally;
Then, extract a twisted pair wire arbitrarily out at the other end of cable, utilize other each root single line of described test circuit one this cut cable of termination, the other end is connected respectively with this twisted pair wire, if signal output is all arranged, then this twisted pair wire breaks; If no signal output, broken string appears in then relative single line.Particularly, as shown in Figure 4, extract a pair of heart yearn of cable left end, pilot lamp one is terminated on all other single lines of this end then, the other end is connected with the single line of this a pair of heart yearn respectively, and is same, if pilot lamp is bright, then the corresponding single line of explanation does not have broken string; If pilot lamp does not work, then disconnection fault appears in explanation.
By above-mentioned detection method, can when the cable semi-manufacture, just can in time find defective, prevent the semi-manufacture operation, cause unnecessary loss, the product that providing of next process is qualified is provided.
The foregoing description only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage who is familiar with this technology can understand content of the present invention and enforcement according to this; can not limit protection scope of the present invention with this; not necessarily adopt pilot lamp as test circuit; also can adopt hummer; perhaps utilize multimeter to measure, all equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
