Description

Wire INCLUDING CABLE FOR SECURITY FENCE}

The present invention relates to a network for security nets capable of cutting detection, and more particularly, to a network for security nets that can detect intrusion from the outside by cutting a built-in communication cable when cutting a core by embedding a communication cable in a tube-type iron core tube. It is about.

In general, where industrial and military confidentiality and security are required, such as fixed-industry, defense contractor, or important military installations, in order to prevent external intrusions and to detect early intrusions, Types of security are installed. A security fence, or security net, is one of these security facilities.

A general security fence, as shown in Figure 1, has a structure for supporting the security net 10 with a vertical support 12 and a horizontal support (14). Such a network is installed to surround a place where security is required. In order to prevent a wall wall, a height of an iron fence may be raised or a barbed barbed wire may be spirally installed on the upper fence.

In addition, various monitoring devices may be installed to monitor outside intruders penetrating the security network. Electronic devices such as video cameras and access sensors may be used as surveillance devices, but these devices are not only expensive but also difficult to maintain after installation and costly to maintain. In addition, since the monitoring function of the external intrusion is temporarily lost in the case of failure of such a monitoring device, the provision of supplementary measures related to this has always caused a management problem.

Recently, security fences using optical fibers have been introduced. The security fence of Israel's TRANS No. F-5000 has a structure in which an additional optical fiber network made of optical fiber cable is installed on the existing wire mesh. In the case of the security fence, the existing wire mesh functions as a physical obstacle, and the added fiber network detects the optical breakage caused by the cutting of the optical fiber at the monitoring station or the observation station to prepare for external intrusion. Then, in preparation for the moon, an upward-tensioned fiber-optic cable is installed on the top of the security fence. By monitoring the signal change caused by tension generated when the fiber cable is pulled at the wall, the wall can be recognized.

In addition, Yayl's product uses a method of connecting the sensor to the left and right wires while installing a tension sensor to detect the tension change on the vertical support of the existing fence. In order to penetrate and penetrate the wire from the outside, the wire should be brightened to increase or ride up the hole of the wire. At this time, only the tension from either the left or right side of the sensor becomes larger, resulting in an unbalanced tension. When it is detected.

The biggest problem of this conventional method is that the construction of the security fence is expensive. The optical fiber method is electrically stable, but the product is expensive and difficult to maintain. Tension sensors also have the disadvantage of being expensive. In addition, since the additional equipment for intrusion monitoring must be additionally installed separately from the existing fence, the installation work of the security network must be made in duplicate, which requires much effort for installation. In order to construct a complete security network, it is necessary to install additional optical fibers or tension sensors with high density. In this case, installation cost and installation time will be doubled.

In order to solve the problems of the above-mentioned prior art, the present invention provides a security mesh that has a security mesh itself, which also has a communication function in addition to a mechanical protection function, and a security fence manufactured by using such a security mesh. The purpose of the present invention is to reduce the installation cost and installation effort of the security fence by enabling the construction of a security fence without separately adding an intrusion detection sensor such as a cable or a tension sensor to a conventional wire mesh.

In order to achieve the above object of the present invention, the wire mesh of the security fence according to the present invention is made of a metal or a high-strength polymer compound and the tubular protective cover having a through hole in the longitudinal direction, and the electrical signal or optical signal The outer surface is made up of one or more strands of conductors insulated and covered with a communication cable inserted into the through hole of the protective cover. The wire of the communication cable may be composed of an insulation coated enamel wire or an optical fiber. The protective cover metal material may be any one of iron, brass, stainless steel or aluminum, and the polymer compound may be any of aliphatic and aromatic polyamides, polycarbonates, or polyolefins. Use one. In addition, the protective cover may be coated with a synthetic resin material, for example, vinyl.

Hereinafter, with reference to the accompanying drawings, it will be described in detail the present invention through an embodiment of the present invention.

2 is an enlarged view of a part of a security network according to the present invention, Figure 3 shows a network for the security network according to the present invention.

Referring to the drawings, the security net mesh 20 of the present invention is composed of a tubular mesh 22 made of steel or galvanized iron and the outside of the mesh 22 is covered with a synthetic resin coating material 24 such as vinyl desirable. Of course, it may not be coated with the coating material 24 at the time of manufacture. The mesh wire 20 should have a mechanical strength and tensile strength that is difficult to cut unless the cutter 20. As long as these conditions are satisfied, the material can be either metal or a high molecular compound. Examples of metals that can be used include iron, brass, stainless steel or aluminum. In addition, the polymer compound may be excellent in mechanical strength and tensile strength, such as aliphatic and aromatic polyamides, polycarbonates, or polyolefins.

The inside of the tube of the tubular mesh 22 is a communication cable 30 composed of electrical conductors 32 coated with an insulating material 34 is embedded. The communication cable 30 may be composed of, for example, an enamelled wire of 0.5 to 1.2 mm. If there is no need to consider cost constraints, the communication cable 30 may be constructed of optical fibers.

To produce such a mesh, the mesh of the present invention can be manufactured by forming a tubular mesh 22 and inserting the communication cable 30 into the tubular mesh. In order to facilitate insertion, the diameter of the through hole of the tubular mesh 22 needs to be slightly larger than the outer diameter of the communication cable 30. Manufacturing can be completed by inserting the communication cable 30, but the communication cable 30 is inserted into the tubular network 22 and then drawn out the network 22 so that the communication cable 30 is in close contact with the network 22. It is also possible to add a further process.

By using such a network, it is possible to construct a fence security net having various types of mesh structure. The security net needs to be dense enough to be intruded without cutting it off the outside. A fence of the form as shown in FIG. 1 is installed using the security network configured as described above. Therefore, if the fence is configured using the security net according to the present invention, since the external fence is not distinguished from the general fence composed of the wire mesh, the external exposure to the security equipment can be protected. In the above-mentioned prior art, since a component having a security function is installed outside the wire mesh, the presence of the security function can be identified to the outside.

Figure 4 is a view for explaining the detection of the cutting of the wire mesh fence fence according to the present invention. That is, in the present invention, weaving the security net 10 by using a tubular mesh with the communication cable 30 is built, and install the fence using the vertical support 12 and the horizontal support (14). Both ends of the communication cable 30 embedded in the tubular network 20 is electrically connected to the monitoring device 100 installed in the central monitoring room using the conductive wire 50 and supplies current to the communication cable 30. In the case where the communication cable 30 is formed of an optical fiber, an optical signal may be supplied. The wire 50 is preferably buried underground to avoid external exposure. That is, the conductive wire 50 and the security net 10 are configured to form a closed loop for the electric signal or the optical signal provided from the monitoring device 100. The monitoring device 100 is provided with a signal detecting means such as an ammeter or a voltmeter to monitor the current flowing in the wire or to monitor the voltage applied to the wire.

When the network is cut to intrude from the outside, the communication cable is also cut at the same time, so that the flow of electric or optical signals through the communication cable is blocked. The monitoring apparatus 100 determines whether there is an intrusion from the outside by always detecting whether the flow of the electric signal or the optical signal is blocked.

As described above, according to the present invention, since the security system is automatically installed at the same time when the security network is installed by embedding a communication cable inside the network for the security network, the installation cost is low and the installation is simple. In addition, since the communication cable is embedded inside the mesh, durability is not only good but there is no cutting error due to other causes than cutting by intrusion. In addition, since it is identical to the existing security network in appearance, it is excellent in confidentiality.

Although described above with reference to a preferred embodiment of the present invention, those skilled in the art various modifications and variations of the present invention without departing from the spirit and scope of the present invention described in the claims below I can understand that you can.
