Abstract
Description
Technical Field
[0001] This utility model belongs to the field of perimeter security technology, specifically relating to a perimeter security device based on a vibrating cable. Background Technology
[0002] To prevent illegal intrusion, perimeter security systems are required for important facilities such as rail transit parking lots, depots, and airports. Currently, widely used systems include tension fences, vibrating cables, vibrating fiber optic cables, microwave beam detectors, infrared beam detectors, laser beam detectors, and pulsed electronic fences. Vibrating cables convert the deformation and pressure caused by external intrusion into electrical signals, enabling the detection of intrusion within the protected area. They feature high detection accuracy, moderate price, low false alarm rate, and high positioning accuracy, and integrate well with video surveillance systems, making them widely used in perimeter protection.
[0003] Vibration cables are typically used in flexible fences but are not suitable for post-type wrought iron fences. Laying vibration cables directly on post-type wrought iron fences will significantly impact the system's accuracy and precision. This is because post-type wrought iron fences use discontinuous iron railings; the posts are brick-concrete structures, resulting in inconsistent vibration signals with the fence. Furthermore, installing vibration cables on post-type wrought iron fences is more difficult and therefore unsuitable.
[0004] While it's possible to install vibrating cables on top of the wrought iron post fence by adding a flexible mesh, the cost of this installation is high. Furthermore, fallen leaves along the perimeter require regular manual cleaning, making maintenance difficult and labor-intensive. Additionally, the added mesh clashes with the style of the post fence, affecting its aesthetics.
[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0028] Example 1
[0029] See attached document Figure 1-4 A perimeter protection device based on a vibrating cable, comprising:
[0030] The bracket 1 is fixed to the wall post. The upper half of the bracket has two or more wire holes 2 at intervals, the middle half has a hook 7 welded on, and the lower half has two bolt holes 3 at intervals. The top of the bracket 1 is equipped with a decorative head 8, which can be round, pointed, or decorated with various shapes.
[0031] Three vibrating steel wires 4 are arranged in parallel on the bracket 1; the two ends of the vibrating steel wires 4 located at the upper end and the middle end pass through the wire holes 2 at the corresponding positions respectively, and the two ends of the steel wire located at the lower end are fixed to the hooks 7 at the corresponding positions respectively.
[0032] The connecting rod 5 is mounted on two adjacent vibrating steel wires 4, and each end of the connecting rod 5 has two fixing plates 6. There is a limiting groove 1 between the two fixing plates 6 at one end of the connecting rod 5 for one vibrating steel wire 4 to pass through, and a limiting groove 2 between the two fixing plates 6 at the other end for one vibrating steel wire 4 and one vibrating cable 9 to pass through. After the fixing plates 6 fix the vibrating steel wire 4, they are clamped with tools.
[0033] In this embodiment, the bracket 1 is made of steel plate, and expansion bolts are used to fix the bracket 1 to the wall post through bolt holes 3 at the bottom. The height of the bracket 1 is adjusted according to the height of the fence, generally 800mm~1000mm. The bracket 1 adopts an arc-shaped structure and is installed on the side of the wall post. Alternatively, when the bracket 1 is installed on the top of the post, a straight type can also be used, but a base needs to be added.
[0034] The upper part of the bracket 1 has two threaded holes 2 spaced apart to secure the two vibrating steel wires 4 at the top and middle. A hook 7 is welded to the middle of the bracket 1 to secure the lower vibrating steel wire 4. The lower vibrating steel wire 4 is flush with the top of the fence to prevent climbing; or flush with the crossarm of the wrought iron fence to improve the overall aesthetics of the installation. If the fence posts can be drilled for threading, the hook 7 can be removed and replaced with threaded holes 2.
[0035] The lower half of the bracket 1 has two bolt holes 3 spaced apart, and the bracket 1 is fixed to the wall post with expansion bolts. The spacing between the wire holes 2 and between the hook 7 and the wire hole 2 next to it is 250~350mm, which can be adjusted according to the actual project; the spacing between the bolt holes 3 is 200~300mm, which can be adjusted according to the spacing of the wall posts and the cable tension.
[0036] In actual installation, bracket 1 is mounted on the wall post, and the vibrating steel wire 4 is laid on bracket 1. The vibrating cable 9 is tied to the middle vibrating steel wire 4 with stainless steel cable ties. Connecting rod 5 connects the vibrating steel wire 4 and the vibrating cable 9, transmitting the vibration signals from the upper and lower vibrating steel wires 4 to the vibrating cable 9. Simultaneously, connecting rod 5 also serves to fix the vibrating steel wire 4, reducing the vibration impact caused by natural factors such as wind and rain. This embodiment expands the detection range of the vibrating cable 9 by using the vibrating steel wire 4, which can reduce the laying length of the vibrating cable 9, thus reducing project investment and improving the economic efficiency of the project.
[0037] This utility model discloses a perimeter security device based on a vibrating cable. The vibrating steel wire 4 expands the detection range, the connecting rod 5 transmits the vibration signal, and the bracket 1 is easy to install, simple and beautiful, and has good applicability. It solves the problem that the vibrating cable 9 cannot be directly applied to the perimeter wall of the column-type wrought iron fence, expands the application scenarios of the vibrating cable 9 in perimeter security, is very practical, and has good market application prospects.
