Problems solved by technology

In the case of a large number of signals, network topology is required to meet the requirements of system security, and the signal recognition rate is low, which is prone to false alarms
At the same time, when an alarm occurs, the system can only be used for regional positioning, but not for precise positioning.

Embodiment Construction

[0016] See attached picture:

[0017] The electromagnetic induction vibration cable used for the security system includes a central conductor 2 arranged in the center of a high-density insulator 1, a keyway 3 is symmetrically arranged on both ends of the high-density insulator 1 along the diameter direction, and an induction cable core is suspended in the keyway 3 4. The high-density insulator 1 is coated with an insulating layer 5, a shielding layer 6, and a polyethylene UV sheath layer 7 in sequence.

[0018] The induction cable core 4 is composed of multiple insulated wire cores twisted into bundles, and the outer diameter of the induction cable core 4 is not greater than 1 / 2 of the width of the keyway 3 .

[0019] The shielding layer 6 adopts a double-layer structure, the inner layer 6-1 is made of aluminum-plastic composite film wrapping; the outer layer 6-2 is composed of conductive carbon fiber and silver-plated copper wire in a ratio of 1:2 to form a mesh.

Abstract

The invention discloses an electromagnetic induction type vibration cable for a security system. The cable comprises a central conductor arranged in the center of a high-density insulator, an outer wall of the high-density insulator is symmetrically provided with keyways at two ends along the diameter direction, induction cable cores are arranged in the keyways in a suspended manner, and the outside of the high density insulator is wrapped by an insulating layer, a shielding layer and a polyethylene UV sheath layer in sequence. According to the cable, the structural design is novel, the structure of the cable is reasonably designed according to the requirement of a usage environment of the security system, the usage requirement of the security system is satisfied, the system is simplified, the positioning is accurate, and the anti-electromagnetic-interference performance is excellent.

Description

[0001] Technical field: [0002] The invention relates to a security cable, in particular to an electromagnetic induction vibration cable used in a security system. [0003] Background technique: [0004] Existing vibrating cables for security are generally arranged in segmented defense zones, and each defense zone requires a separate signal receiving and transmitting device, and the signals of each defense zone are finally concentrated to the signal processing terminal. In the case of a large number of signals, network topology is required to meet the requirements of system security, and the signal recognition rate is low, which is prone to false alarms. At the same time, when an alarm occurs, the first-use system can only perform regional positioning, but not precise positioning. [0005] Invention content: [0006] In order to make up for the problems in the prior art, the object of the present invention is to provide an electromagnetic induction vibration cable used in a ...
