Wear-resistant vibration cable with multiple parallel cores

Abstract

The invention relates to a wear-resistant vibration cable with multiple parallel cores. An inner sheath layer is coaxially sleeved in an outer sheath layer; an outer sheath adopts a wear-resistant flame-retardant polyurethane material, and the inner sheath layer adopts a polyethylene material; an elliptic polyester aluminum-plastic composite layer is coaxially sleeved in the inner sheath layer, a metal woven mesh is coaxially embedded in the polyester aluminum-plastic composite layer, a polyester film layer is coaxially sleeved in the polyester aluminum-plastic composite layer, and two directionally-slotted rubber magnetic stripes which are parallelly arranged on an upper part and a lower part along a cable direction and have different magnetic properties are coaxially sleeved in the polyester film layer; and parallel integrated signal wires are arranged on the center part in the two directionally-slotted rubber magnetic stripes, and a vibration line in mirror symmetry is movably arranged in each directionally-slotted rubber magnetic stripe between the parallel integrated signal wires and the polyester film layer. The vibration cable opens up a new path in the field of warning cables, has an intelligent warning function with a very low rate of false alarm and has strong blocking effect and deterrent effect, so that the perimeter security precaution technology of China goes up to a new stage.

Description

technical field [0001] The invention belongs to the field of cables and relates to a vibration cable, in particular to a multi-core parallel wear-resistant vibration cable developed by applying the principle of electromagnetic induction. Background technique [0002] With the advancement of science and technology, new requirements have been put forward for the perimeter security of some complex-terrain perimeter areas, high-end residential quarters, power plants, warehouses for inflammable and explosive materials, and important buildings. Compared with the traditional perimeter security products, the warning cable has more advantages: for example, the traditional infrared monitoring system cannot block the intruders. Although the high-voltage power grid can play a strong blocking role, due to the strong AC It can cause personal injury or even death, which is very dangerous. [0003] However, due to the structure, the existing warning cables are prone to bending and displace...

Compared with the traditional perimeter security products, the warning cable has more advantages: for example, the traditional infrared monitoring system cannot block the intruders. Although the high-voltage power grid can play a strong blocking role, due to the strong AC Can cause personal injury or even death, very dangerous

[0003] However, due to the structure, the existing warning cables are prone to bending and displacement, and the wiring is difficult. They cannot be erected arbitrarily with the ups and downs of the terrain. Many unsatisfactory things
