Description
Technical field：
It the utility model is related to security protection cable, more particularly to a kind of induction vibration wireline for safety-protection system.
Background technology：
Existing security protection typically arranges that each defence area needs single signal to connect with vibration wireline using segmented defence area
Receive, transfer device, the signal in every defence area finally focuses on the signal processing terminal.Also needed in the case of more than number of signals into
Row network opens up the requirement mended and could meet system security protection, and signal identification rate is low, the situation of false alarm easily occurs.Meanwhile when
When alarming, zone location first can only be carried out with system, and can not be accurately positioned.
Utility model content：
In order to make up prior art problem, the purpose of this utility model is to provide a kind of electromagnetic induction for safety-protection system
Formula vibration wireline, the requirement of security protection is met, have the characteristics that safety-protection system is simple, registration..
The technical solution of the utility model is as follows：
Induction vibration wireline for safety-protection system, it is characterised in that：Including being arranged in high density insulator
The center conductor of the heart, diametrically both ends are symmetrically arranged with keyway on high density insulator outer wall, suspend and are provided with keyway
Sense cable core, insulating barrier, screen layer, polyethylene UV restrictive coatings are coated with successively outside high density insulator.
The described induction vibration wireline for safety-protection system, it is characterised in that：Described sensing cable core has more
Root insulated wire cores are twisted bunchy and formed, and sensing conductor assembly outer diameter is not more than the 1/2 of width of keyway.
The described induction vibration wireline for safety-protection system, it is characterised in that：Described screen layer is using double
Rotating fields, internal layer use the wrapped composition of aluminum-plastic composite membrane；The conductive carbon fibre of outer layer is with silver-gilt copper wire according to 1:2 ratios are woven into
Netted composition.
The utility model has the advantages that：
The utility model novel in structural design, the construction of cable is rationally designed according to the demand of safety-protection system use environment,
The requirement of safety-protection system is met, system is simplified, registration；Additionally there is excellent electromagnetism interference performance.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
Embodiment：
Referring to accompanying drawing：
For the induction vibration wireline of safety-protection system, including it is arranged on the center at the center of high density insulator 1 and leads
Body 2, diametrically both ends are symmetrically arranged with keyway 3 on the outer wall of high density insulator 1, are suspended in keyway 3 and are provided with sensor cable
Core 4, high density insulator 1 are coated with insulating barrier 5, screen layer 6, polyethylene UV restrictive coatings 7 successively outside.
Sensing cable core 4 has more insulated wire cores to be twisted bunchy composition, and sensing cable core 4 external diameter is not more than the 1/ of the width of keyway 3
2。
Screen layer 6 uses double-decker, and internal layer 6-1 uses the wrapped composition of aluminum-plastic composite membrane；Outer layer 6-2 conductive carbon fibre
With silver-gilt copper wire according to 1:The braiding of 2 ratios reticulates composition.
Operation principle：Extraneous physical vibration causes induction cable to produce relative to central coaxial cable and external cable
Relative displacement, displacement cutting magnetic line and produce induced-current, will be detected by the domain reflectometer displacement and carry out essence
It is determined that position.
