Description

The invention relates to signaling barriers based on spiral elements and is intended to protect the perimeters of objects and extended lines of protection on flat and rough terrain.

Known designs of mobile barriers (RF patent No. 2315159, publication date 01/20/2008, RF patent No. 98456, publication date 12/27/2010) containing three spirals of the same diameter from barbed tape reinforced with a wire core, oriented relative to each other in the shape of a triangular prism, with all the turns of adjacent spirals pairwise interconnected at points of contact uniformly distributed around the circumference of the coil and located on one straight line along the length of the spiral, while the blocks of mobile barriers are equipped with or tainer from two metal frames that can be opened with locks with eyelets for fixing the carcasses on the ground and with one another, or metal bars, stapling and packing tape.

The use of the considered structures makes it possible to protect the object by providing the possibility of injuring the intruder in contact with the barbed wire barbed elements when trying to overcome the spiral fence directly. However, when the spiral coils are moved apart or their other deformation is penetrated into the protected area, it becomes possible, which indicates insufficient protective ability of the structures. Also, the installation of barriers on the ground is manual, requires the installation of end coils equipped with containers or metal gratings, which increases the complexity of the work.

A known design of a security device based on a spiral fence (RF patent No. 2425200, publication date 07/27/2011), adopted as the closest analogue to the claimed solution and containing three spirals of the same diameter from a barbed tape reinforced with a wire core, oriented relative to each other in in the form of a triangular prism in such a way that the two lower spirals make up the base, and the third upper spiral - the top of the prism, and all the turns of adjacent spirals are paired together at points in contact eniya located on one straight line along the length of the helix, the apparatus comprising a vibration detecting means having two cable-sensitive element, the bottom and upper, the lower sensitive element is fixed on one of the lower spirals along its length and with an angular spacing φ ₁ 0 up to 90 ° relative to the equator, and the upper sensitive element is mounted on the upper spiral parallel to the lower sensitive element and with an angular distance ϕ ₂ from 0 to 90 ° relative to the equator of this spiral, while under the equator spiral refers to the horizontal plane passing through the center of the spiral loop. Cable sensitive elements are made on the basis of special triboelectric cables that are susceptible to vibration.

The considered design of the fence involves the installation of a signal processing unit in the form of a removable metal housing with a bracket, with which it is installed, for example, inside the cabinet to protect it from weathering and mechanical damage. As a result, when using triboelectric cables as cable sensitive elements, it is necessary to install one cabinet with a signal processing unit in each section of the fence 250-300 m long or use a cabinet with a double processing unit located in the middle between two protected sections with a total length of 500-600 m (http://uchebnik.online/uchebnik-predprinimatelstvo/vibratsionnyie-sistemyi-sensornyimi-40319.html). The presence of attachments makes the design of the fence less mobile and more cumbersome, as cabinets with signal processing units are located throughout the signaling fence. Triboelectric cables are also susceptible to electromagnetic interference, weather, etc. (http://www.secuteck.ru/articles2/OPS/sistemy-ohrany-perimetra-s-sensornym-kabelem-obzor-perspektivnyh-tehnologiy). In this case, additional work is necessary to configure and adjust triboelectric cables to minimize false alarms and signal losses during the operation of the fence. In addition, when attempting to climb, cable sensitive elements that are not protected by any sheath on the outside can be damaged, which can lead to the absence of a signal from the cable about the intruder entering the territory. The data presented indicates insufficient protective barrage properties of the considered device.

The objective of the invention is to provide a reliable security device based on a spiral fence with the ability to quickly mount and disassemble on the ground.

The technical result of the invention is to increase the alarm and protective properties of the security device by performing a cable sensing element in the form of an optical module with optical fiber enclosed in a metal sheath.

The technical result is achieved by using a security device based on a spiral fence containing spirals oriented relative to each other to obtain a three-dimensional figure, the turns of adjacent spirals pairwise interconnected at points of contact located on one straight line along the length of the spiral, while the security device contains cable sensing element, which is used as a metal cable with an integrated optical module with optical fiber, fixed to the point kah with an angular distance of 0 ± 90 degrees relative to the equator of this spiral, moreover, the equator of a spiral refers to the horizontal plane passing through the center of mass of the coil of the spiral.

By a three-dimensional figure formed by barrage spirals is meant the concept of a “three-dimensional figure” used in geometry: a part of space bounded by a surface.

The security device may have three or six spirals or any other number of spirals that can be oriented relative to each other, for example, in the form of a triangular prism or any other three-dimensional figure. At the same time, the security device may contain spirals with turns of any possible shape and any size, with the same or different diameter if they are made round. Also, spirals can be performed with cutting elements or without cutting elements (Fig. 1A-1G).

By the center of mass of a coil of a spiral is meant the geometric point inside the coil of a spiral, which determines the mass distribution of this spiral. Determining the position of the center of mass of the system of material points in classical mechanics is determined in a known manner (for example, the Physical Encyclopedic Dictionary. - M .: Soviet Encyclopedia. Edited by A.M. Prokhorov, 1983).

The inventive security device can be made installed directly on the ground or with a deepening in the ground, that is, in the form of an unsupported three-dimensional figure. Also, if necessary, the guarded device can have special supports (for example, poles) to increase the stability of the position.

Upon receipt of a three-dimensional figure from spirals, the lower row of spirals is distinguished, which are located at the base of the figure or are on the ground or buried in the ground; the top row of spirals that are located at the top of the three-dimensional figure; intermediate rows of spirals located between the upper and lower rows of spirals.

Depending on the volumetric figure formed by the spirals, one metal cable with an optical module with an optical fiber integrated inside, located on one of the lower row spirals, can be used, and several metal cables with an optical module with an optical fiber integrated inside, can be used spirals of several rows.

A metal cable acting as an outer sheath for an optical module with optical fiber can be made of steel, titanium, or a special composite material with a high resistance to mechanical destruction by the method of cutting or tearing.

To obtain a mobile version of the security device, cable holders that allow it to slide can be used, which are also fixed at the connection points of adjacent turns of spirals with an angular distance of 0 ± 90 degrees relative to the equator of this spiral, while a metal cable passes through them with an optical module integrated inside fiber optic. Under the cable holder, allowing its sliding, in the framework of the present invention is understood an eye in the form of a bracket in which one of the parts moves relative to the other.

The use of a metal cable as a cable sensing element with an internal optical module with optical fiber allows you to refuse to place cabinets with signal processing units throughout the signal barrage, as well as any elements requiring adjustment and adjustment, due to the use of barricade elements associated with the optical module with optical fiber, which allows to transmit signals with low losses and to collect information immediately from the entire length of the fence in one place ( Shcherbinina V.I., Rusanov Yu.A. Fiber-optic technologies in video surveillance and perimeter security systems http://www.secuteck.ru/articles2/OPS/fib_opt_ss_4_2004).

As a result, a metal cable with an optical module with optical fiber inside it allows you to get a distributed sensor device for recording mechanical effects on the spiral structure of the security fence, which can simultaneously increase the strength of the cable sensitive element and provide the ability to remotely obtain information about the state of the spiral fence on rendering on it exposure, which ultimately increases the alarm and protective properties of the security device . Also, the formation of a three-dimensional figure from spirals of any height, shape and width, depending on the conditions of use, contributes to the increase of the protective properties of the security device.

A security device based on a spiral fence contains spirals 1 oriented relative to each other to obtain a three-dimensional figure, for example, in the form of a triangular prism, while the lower spirals 2 form the lower row of the prism, and the upper spiral 3 is the top of the prism, and all turns of adjacent spirals are paired interconnected at points of contact located on one straight line along the length of spiral 1. Also, the security device contains a cable sensitive element, which is used as a metal cable with built inside an optical module with optical fiber 4, fixed at the connection points of adjacent turns of spirals with an angular distance of 0 ± 90 degrees relative to the equator of this spiral, for example, one metal cable with an integrated optical module with optical fiber 4 is fixed to one of the lower spirals 2, and the other metal the cable with the optical module with optical fiber 4 built inward is fixed in parallel on the upper spiral 3, while the equator of the spiral means the horizontal plane through the center of mass of the spiral ali (FIG. 1a-1d).

The cable holder (Fig. 2a, 2b), through which a metal cable passes with an optical module with optical fiber 4, in the case of receiving a mobile version of the security device, contains an eye 5 made of metal or plastic or plastic, while the eye 5 consists of two parts - movable 6 and fixed 7, each of which has a hole with a diameter that allows a metal cable with an optical cable with optical fiber 4 to slide with low friction. The parts of the eye 5 are interconnected by means of a bending spring plate or spring wire so that the plane of the movable part 6 of the eye 5, in which the plane of the hole for the specified metal cable 4 is located, forms an angle of 20-30 degrees with the plane of the stationary part 7 of the eye 5 and the plane of the hole for the specified metal cable 4. The fixed part 7 of the eye 5 is rigidly fixed to the spiral fence at the points of connection of adjacent turns of the spiral from the outside of the spiral and perpendicular to the axis spiral spiral 1. The movable part 6 of the eye 5 is located at an angle to the fixed stationary part 7 of the eye 5 so that its free end is located inside the coil of the spiral 1. An additional metal cable 8 is attached to the free end of the movable part 6 of the eye 5, the opposite end of which it is rigidly fixed on the nearest adjacent joint 9 of two turns of spiral 1. In the compressed state of spiral 1, the wire ropes 8 are in an unstretched state inside the turns of spiral 1. When stretching the spiral 1, the wire rope 8 smiling, limits its length to the maximum extension of the spiral garland (spiral 1). In this case, when the cable is pulled, the lead 8 bends the movable inclined part 6 of the eye 5, thereby shifting the hole in which the metal cable with the optical module with optical fiber 4 is located, resulting in mechanical action on the specified cable with optical fiber 4, inhibiting its sliding and fixing in the eye 5. Thus, the automatic fixation of the required degree of extension of the spiral.

The choice of the number of spirals is based on obtaining a security device of the required height depending on the conditions of its use, including climatic ones. For example, when used in areas with heavy snowfall, it is necessary to construct a higher spiral fence, for which 6 or more spirals are used to form a three-dimensional figure. In standard cases, a security device can be used, containing three spirals, located, for example, in the form of a prism.

The choice of a tape with or without cutting elements for organizing a security device depends on the degree of danger to people and animals that should not be subject to the protective properties of such a device. At objects where close proximity of people, children and animal migration is possible, the use of spirals made of tape with cutting elements is prohibited. In this case, it is possible to use all spirals from a tape without cutting elements or a combination of spirals from two types of tape using a tape without cutting elements from the side where contact with people and animals is possible.

Installation of a stationary security device for the terrain is possible in several versions.

According to the embodiment of FIG. 3, the security device is installed on the ground permanently. On the perimeter of the protected object, spiral garlands (spirals 1) unfold, which are then stacked on top of each other with the formation of a prism or other three-dimensional figure. Adjacent spirals from a tape without cutting elements are fastened with brackets, spirals from a tape with cutting elements are engaged due to the presence of cutting elements.

In the soil 10, a multicore optical communication cable 11 is laid over the entire length of the obstacle, which is connected to the optical transceiver unit 12, the computer signal processing unit 13, which has a monitor for displaying information 14, and an uninterruptible power supply unit 15. At certain selected intervals (protection sections) 16 optical communication cable 11 sealed optical couplings 17 of various designs and sizes are installed, as a rule, commercially available by various manufacturers, with passive interference national converters. Also, at each selected guard interval 16, a metal cable with an optical module with an optical fiber 4 located inside, which is fixed with integral metal clamps, passes through the lower 2 and upper 3 spirals in the form of loops 18. Moreover, the beginning and end of the specified metal cable 4 in the form of loops 18 is in the corresponding sleeve 17.

According to the embodiment of FIG. 4, the security device is mobile and is implemented as follows.

On the spirals 1, in the production process, cable holders are installed - eyes 5, metal cables with an optical module with optical fiber 4, which pass through all eyes 5. An optical communication cable 12 and a metal cable with an optical module with optical fiber 4 located inside are passed through the bottom row of 2 spirals. At selected intervals - protection sections 16, couplings 17 are installed through which a cable 4 and a communication cable pass 11. In each clutch 17, a cable segment with an optical module 4 branches off, at the end of which a terminal cable is mounted a trap 19 for returning the signal along the same path back to the clutch 17 and transmitting via a communication cable 11 to the computer signal processing unit 13. In this case, the reflector 19 of the branch part of the cable 4 is fixed on the top row 3 of the spirals, and its length is equal to the selected guard 16.

The spiral garland (spiral 1) is compressed by winding a metal cable with an optical module with optical fiber 4 onto the shaft using a manual or mechanical drive. Compressed spiral 1 is placed in a metal container and installed in a car trailer or car body. At the object, the shaft is released, the first turn of the spiral 1 is fixed on the surface of the earth and when the car moves, it is unclenched. In this case, the metal cables with the optical module 4 slide through the eyes 5 until the cable-lead 8 is tensioned and does not limit the further stretching of the spiral 1, while simultaneously fixing the metal cable in the eye 6 with the optical module 4.

According to FIG. 5, a metal cable with an optical module with optical fiber 4 passes through the upper 3 and lower row of spirals 2 together with the communication cable 11 along the entire length of the fence and is connected to the computer signal processing unit 13.

The general principle of operation of the security device is based on the photoelastic effect. When you try to cross a spiral fence in any way, the intruder produces a mechanical effect on the elements of the spiral. The deformation of the spiral leads to the deformation of the metal cable with the optical module and, accordingly, to the bending or microbending of the optical fiber inside the cable. The bending of the optical fiber leads to stresses in the material of the optical fiber, which is accompanied by a local change in the refractive index and, accordingly, modulation of the phase of the light waves propagating in the optical fiber. The interference of various coherent components of light waves, for example, the interference of optical fiber modes, converts phase modulation to amplitude.

Registration and analysis of amplitude modulation in time in a computer unit for signal processing allows you to obtain information, the processing of which allows you to recognize the nature of the impact and decide on the generation of the Alarm signal.

The inventive security device allows for reliable protection of the object. When you try to push or deform the coils of a spiral, a vibratory detection means is triggered. In addition, the use of a metal cable as an outer sheath can increase the strength of the cable sensing element even under strong mechanical stress. In addition, a metal cable is able to prevent the passage of vehicles to a protected area.

The claimed technical solution has several significant advantages, namely:

- no need to use additional equipment with the involvement of staff;

- providing quick installation and dismantling of the device when using a metal cable, which simultaneously acts as a cable for compressing and stretching a spiral fence and a distributed sensor device for recording mechanical influences and obstacles for vehicles, which significantly expands its functionality;

- providing visual and television control of territories both inside the fence and from its outside.
