Description

[0001] The present invention relates to a security fence-

The present invention relates to a security fence sensing apparatus, and more particularly, to a security fence sensing apparatus which comprises an upper line or a lower line of a security fence as an optical cable and cuts the upper line or lower line every predetermined interval, A security fence connection type in which when the upper line or the lower line is pulled by an intrusion attempt, the connection part is separated to detect the deformation of the flow of light, thereby detecting intrusion into the upper or lower line of the security fence Sensing device. In the present invention, " intrusion " is used to mean " escape. &Quot;

1 is a typical security fence 10 in which a security fence body 11 is provided with a barbed wire 3 between several struts 4 and an optical fiber 1 is connected to the barbed wire 3 A zigzag pattern such as a bar, or a hexagonal pattern. The upper (12) or lower (13) of the security fence is not provided with a barbed wire but only an optical fiber network is installed. A clip for fixing the optical cable 1 adjacent to each other in order to prevent the intruding by increasing the size of the net.

The net of such an optical fiber network can not pass through a security fence without removing the optical cable (1) because it is a size that can not be passed by a person. Therefore, if the optical cable 1 is damaged by cutting or bending the optical cable 1 to intrude, the flow of the light flowing through the optical cable 1 is deformed, so that the detection system connected to the optical cable 1 senses this.

Meanwhile, such a security fence has a problem that it can not be detected when it goes beyond the security fence by using a ladder or the like and does not damage the optical cable, or when the security fence penetrates to the bottom of the security fence. In order to solve such a problem, the present applicant has proposed a patent invention (wormhole sensing device) 10-0732035 and received a patent.

However, the above-mentioned patent 10-0732035 has another problem in that it takes a lot of time, money, and manpower to install and maintain the sensor since a rather complicated sensing device composed of a fixed body and a fluid must be installed every interval.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a security fence sensing apparatus which can easily manufacture, install and maintain, and requires very little time, cost, and manpower for manufacture, installation and maintenance.

In order to accomplish the above object, the present invention provides a security fence comprising an upper line or a lower line of an optical fiber, an upper line or a lower line being cut at every predetermined interval and physically connecting the cut ends to a splice, When the upper line or the lower line is pulled by the intruder, the connection part separates and senses that the light flow is deformed, and detects intrusion into the upper or lower line of the security fence.

The upper or lower line of the security fence is constituted by an optical cable, and the upper line or the lower line is cut at every predetermined interval. Then, the cut ends are physically connected to the connector, It is detected that the connection part is separated and the light flow is deformed when it is pulled, so that it is detected that it penetrates above or below the upper line or the lower line of the security fence. Therefore, the structure is very simple, There is an effect that the time, cost, and manpower required for manufacture, installation, and maintenance are very small.

Figure 1 is a typical security fence
2 is a partial view of a conventional optical fiber network.
3 is a configuration diagram of the connected type sensing apparatus of the present invention,
4 is a security fence in which the connected sensing device of the present invention is installed.

Optical fiber has a hair-like optical fiber at its center, which is wrapped with aramid yarn and protects it. At the same time, its tensile strength is increased and its outer surface is coated with a soft petrochemical product. When the optical fiber is cut, the flow of light through the optical cable is deformed.

The present invention utilizes the characteristics of the optical cable as described above. The optical fiber cable comprises an upper line or a lower line of the security fence, and the upper line or the lower line is cut at every predetermined interval, and the cut ends are physically connected to the splice If the upper line or the lower line is pulled by the intruder, the connection part separates and senses that the light flow is deformed, and detects intrusion into the upper or lower line of the security fence.

BRIEF DESCRIPTION OF THE DRAWINGS Fig.

As shown in FIG. 3, the security fence-connected type sensing apparatus of the present invention includes a box-shaped enclosure 20 having left and right optical fiber holes 21, And a pipe-shaped connector (40) laid between the stator (30) and the stator (30) on both sides.

The front part 22 of the housing 20 can be opened and closed so that the front part 22 is opened and the installation operation is completed and the front part 22 is closed so that it is not opened arbitrarily.

When the security fence-connected sensing device of the present invention is installed, the front portion 22 of the housing 20 is opened and the upper line 5 or the lower line 6 is connected to the optical cable hole 21 of the housing 20 The upper end line 5 or the lower end line 6 inside the enclosure 20 is cut to remove the coating on both ends and then the both ends are pushed from both ends of the pipe-like connector 40, Physically connected. It is preferable that the connector 40 is made of a transparent material so that both ends of the upper line 5 or the lower line 6 can be pushed in or the connection state of both ends can be confirmed.

Since the upper end line 5 or the lower end line 6 thus cut is physically connected again, there is no problem in the flow of light, and even if the cut ends are not properly connected and there is a small gap between the both ends, There is no obstacle.

The upper line 5 or the lower line 6 is attached to the stator 30 provided on both sides of the inside of the housing 20 so that the physical connection state of the cut top line 5 or the bottom line 6 is maintained. Fix both sides.

When the upper line 5 or the lower line 6 is pressed down or pushed up to pass through the security fence provided with the security fence connected type sensing apparatus of the present invention, The lower end line 6 is pulled beyond the fixing force of the stator 30 so that the connection portions of the upper end line 5 or the lower end end line 6 physically connected in the interposer 40 are separated, do.

When the connecting portions of the upper end line 5 or the lower end line 6 physically connected in the connector 40 are separated and the interval between the both ends is increased, the upper end line 5 or the lower end line 6, and the deformation of the flow of the light is detected by a detection system (not shown) such as an OTDR (Optical Time Domain Reflectometer) connected to the optical cable, and an alarm is issued.

As described above, according to the present invention, an upper line or a lower line of a security fence is constituted by an optical cable, the upper line or the lower line is cut at every predetermined interval, and the cut ends are physically connected to the splice, When the lower line is pulled, the connection part separates and detects the deformation of the flow of light, so that it detects the intrusion into the upper or lower line of the security fence. Thus, the structure is very simple, It is simple to use and requires very little time, cost and manpower for manufacturing, installation and maintenance.

While the present invention has been described with reference to the exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but is capable of various changes and modifications within the technical scope of the invention. Therefore, the scope of the present invention is not limited by the above description.

Further, the detailed description of the present invention and the reference numerals in the claims are provided for ease of understanding of the present invention, and the present invention is not limited to the drawings.
