Problems solved by technology

The above installation method may directly touch the optical cable because of the intrusion, or it may touch the fence grid and then indirectly transmit it to the optical cable. It has a lot of randomness, which is affected by the material characteristics of the fence grid. Every installation must debug the signal analysis method to adapt to the different characteristics of different fences

Embodiment 1

[0032] figure 1 A schematic situation of the installation of the sensing optical cable of the present invention on the top of the protective fence is given, including the sensing optical cable and the fence. The sensing optical cable is placed on the top of the fence and runs in a straight line parallel to the fence. There is a tubular structure wrapped outside the sensing optical cable. In the perimeter security system. There is a small column every 30 cm on the top of the fence, and the upper ring bracket can hold and fix the sensing optical cable, and place the sensing optical cable at a position 0.5 cm higher than the top of the fence. The sensing optical cable is wrapped in a metal tubular structure, which can return to its original shape after being pressed by an external force and released, thereby generating a stable and reliable intrusion signal. The tubular structure can be sleeved on the sensing optical cable in sections, or covered on the sensing optical cable by ...

Embodiment 2

[0034] Embodiment 2 is slightly different from Embodiment 1, including the sensing optical cable and the fence. The sensing optical cable is placed on the top of the fence, and its exterior is wrapped with a tubular structure for use in the perimeter security system. There is a small column every 200 centimeters on the top of the fence, and the upper ring bracket can hold and fix the sensing optical cable, and place the sensing optical cable at a position 10 centimeters higher than the top of the fence. The sensing optical cable is wrapped in a tubular structure made of rubber, which can return to its original shape after being pressed by an external force and released, thereby generating a stable and reliable intrusion signal. The tubular structure can be sleeved on the sensing optical cable in sections, or covered on the sensing optical cable by two sections of semicircular section tubular structures. Other methods can also be used to place the sensing optical cable in the p...

Embodiment 3

[0036]Embodiment 3 is slightly different from Embodiment 1, including the sensing optical cable and the fence. The sensing optical cable is placed on the top of the fence, and its exterior is wrapped with a tubular structure for use in the perimeter security system. The sensing optical cable is an outdoor single-mode communication optical cable. There is a small column every 50 centimeters on the top of the fence, and the upper ring bracket can hold and fix the sensing optical cable, and place the sensing optical cable at a position 5 centimeters higher than the top of the fence. The sensing optical cable is wrapped in a tubular structure made of elastic material, which can return to its original shape after being pressed by an external force and released, thereby generating a stable and reliable intrusion signal. The tubular structure can be sleeved on the sensing optical cable in sections, or covered on the sensing optical cable by two sections of semicircular section tubula...

Abstract

The invention discloses an optical cable fence system, and belongs to the technical field of monitoring. The optical cable fence system comprises a sensing optical cable and a fence, wherein the sensing optical cable is positioned on a frame at the top of the fence and is in straight line parallel to the trend of the fence; and the outside of the sensing optical cable is wrapped by a tubular structure enabling the optical cable to deform under the oppression of external force and to restore after the external force is released. The optical cable fence system is suitable for universal mounting of all fences, enhances an optical detection signal, improves the signal-to-noise ratio, lowers system installation and maintenance costs, and significantly improves structural invisibility.

Description

technical field [0001] The invention belongs to the technical field of monitoring, and in particular relates to an optical cable fence system for monitoring and alarming. Background technique [0002] One of the main tasks of the security monitoring system is to identify perimeter intrusion events in real time, and the fiber optic cable fence plays an important role in the security monitoring system. [0003] The fiber optic cable fence represents the most advanced security technology at present. Through the sensing fiber optic cable, the perception of abnormal perturbation around the fence is used for pattern recognition, so as to determine whether there is an intrusion and accurately locate the location of the intrusion. The sensing cable is a sensor for sensing the presence of an intruder or sensing whether the fence is breached. The sensing optical cable is connected with the signal receiver, and the collected signal is output to the signal receiver in time. By analyzi...
