Description
Technical field:
The present invention relates to a kind of generic cabling engineering network hunting technologies, exempt from terminating based on actinobolia more particularly to a kind of
Network line-hunting method and device.
Background technique:
With the development of information telecommunications, comprehensive wiring system is as a kind of basis being made of communication cable and connection hardware
Weak electricity system has been used widely in the development of urban informationization.For convenient for managing and maintaining, " integration laying line system engineering
Design specification GB 50311-2016 " component parts such as regulation each cable of comprehensive wiring, optical cable, distribution plant, termination point
Unique identifier should all be given, and label should be set, the both ends of cable and optical cable should all indicate identical identifier.From construction
Angle says, lays before cable it is ensured that cable mark is carried out at both ends.For the pair twist cable in wiring subsystem, if not having
Have and complete to lay in the case where pasting cable mark, then needs to carry out identification correspondence to cable both ends using hunting instrument, otherwise can
Form chaotic wiring.And current line-hunting method must be just implementable after one end Cheng Duan of cable, that is, needs to install water
Brilliant connector terminates to cable on network wiring frame or information socket module.This situation comprehensive wiring system be transformed or
It is relatively common in the nonstandard engineering construction of person's process.If be related to number of cables much especially with Shielded Twisted Pair when, this
The traditional hunting scheme of kind can then expend many time and manpower, reduce construction efficiency, result in waste of resources.
Summary of the invention:
The technical problems to be solved by the present invention are: overcoming the deficiencies of the prior art and provide, a kind of design is reasonable, it is fast to facilitate
The successive of cable laying and mark production is required, made for searching paired cable that both ends do not terminate, can also relax promptly
The flexibility of construction is stronger to exempt from terminating network line-hunting method and device based on actinobolia.
The technical scheme is that
It is a kind of that terminating network line-hunting method is exempted from based on actinobolia, comprising the following steps:
A, the induction spool for choosing four pairs of unshielded twisted pairs, RJ-45 connector and C-shaped, by one end of four pairs of unshielded twisted pairs
It is installed together with RJ-45 connector, RJ-45 connector is connect with network hunting instrument, since network hunting instrument is input to by kinking pair
Signal polarity in both threads must be identical, therefore must be according to the signal of heterogeneous networks hunting instrument when installing RJ-45 connector
It exports situation and adjusts line sequence；
B, a line pair is extracted from the other end of four pairs of unshielded twisted pairs, is closely wound around C-shaped wall cross-section, along pipe
Axially turn to C-shaped coil；
C, when hunting, the induction spool of cable insertion C-shaped, opening signal generator, the line of induction of the audio signal in C-shaped will be sought
The metallic conductor of insertion cable is injected inside pipe by induction, and is propagated along cable, it is another in cable with hunting instrument signal receiver
End search audio signal can be positioned to being sought cable.
Adhering to one layer of aluminium foil on the surface of the induction spool of C-shaped makes the line of induction of C-shaped to increase effectiveness
Stronger electromagnetic signal is obtained inside pipe.It is covered with one layer of PVC flexible film outside coil, prevents coil from sliding on tube wall
It deforms and is worn.
Online tube outside installs one layer of rigid plastic shell additional, and the fixed part and movable part of plastic shell pass through hinge knot
Structure connection, the end of movable part are bonded with rubber tent, and the latter plays limitation fixed function to the cable of insertion spool.
Spool is made of polyethylene, internal diameter 12-16mm, Opening length 6-8mm, and five classes of insertion can be supported to arrive
Seven class twisted pairs, spool winding portion length are 15cm.
It is a kind of that terminating network hunting device is exempted from based on actinobolia, including four pairs of unshielded twisted pairs, RJ-45 connector and
One end of the induction spool of C-shaped, four pairs of unshielded twisted pairs is installed together with RJ-45 connector, the RJ-45 connector with
The connection of network hunting instrument, extracts a line pair from the other end of four pairs of unshielded twisted pairs, around C-shaped wall cross-section
It is closely wound, axially turns to C-shaped coil along pipe, when hunting, the induction spool that will be sought cable and be embedded in the C-shaped opens letter
Number generator, audio signal are injected the metallic conductor of insertion cable inside the induction spool of the C-shaped by induction, and along cable
It propagates, can be positioned in cable other end search audio signal to being sought cable with hunting instrument signal receiver.
Adhering to one layer of aluminium foil on the surface of the induction spool of the C-shaped makes the C-shaped to increase effectiveness
Incude and obtains stronger electromagnetic signal inside spool；Since network hunting instrument is input to by kinking to the signal polarity in both threads
Must be identical, therefore situation must be exported according to the signal of heterogeneous networks hunting instrument when installing RJ-45 connector and adjust line sequence.
One layer of PVC flexible film is covered with outside the coil, prevent the coil slided on tube wall deformation and by
Abrasion.
The line of induction tube outside of the C-shaped installs one layer of rigid plastic shell, the fixed part of the plastic shell and work additional
Dynamic part is connected by hinge arrangement, and the end of the movable part is bonded with rubber tent, cable of the latter to insertion spool
Play limitation fixed function.
The induction spool of the C-shaped is made of polyethylene, internal diameter 12-16mm, and Opening length 6-8mm can
Support that insertion five classes to seven class twisted pairs, spool winding portion length are 15cm.
The beneficial effects of the present invention are:
1, the present invention is tested cable input audio signal using induction normal direction, replaces traditional direct injection, use is semiclosed
Formula coil can incude injection audio signal from any position of cable, not destroy cable oversheath, it is not necessary to it is required that wearing from cable end
Enter coil, using flexible is quick.
2, when the present invention carries out Shielded Twisted Pair hunting, injection cable audio signal and signal generator output signal strength
It is almost equal.When carrying out unshielded twisted pair hunting, injecting cable audio signal with signal generator output signal strength difference is
The 10-20dB(value is related with cable insulation material), decay relatively large, but preferably differentiates effect from acoustically still having
Fruit；If the sound gain amplifier 10-20dB of hunting instrument receiver can be improved, achieve the effect that same with traditional line-hunting method.
3, the present invention respectively adheres to the aluminium foil of one layer of 0.5mm in the two sides of polyethylene tube wall, to increase effectiveness, makes
Stronger electromagnetic signal is obtained inside c-type spool, overcomes on c-type spool outer coil to the counteracting shadow of the electromagnetic field of inner coil
It rings.
4, the present invention is covered with the PVC flexible film of one layer of 0.2mm outside coil, and coil is effectively prevent to slide on tube wall
It deforms and is worn.
5, the online tube outside of the present invention installs one layer of rigid plastic shell additional, further protects wire tube structure, plastic shell
Fixed part is connected with movable part by hinge arrangement, and the end of movable part is bonded with rubber tent, and the latter is to insertion line
The cable of pipe plays certain limitation fixed function.
6, the present invention is not only suitable for shielding and unshielded twisted pair, and can expand the signal for other with metal core
Line, power supply line and optical cable with metallic strength member etc. can expand the use scope of traditional hunting instrument, reality easy to spread significantly
It applies, it is with good economic efficiency.
