Abstract

A combined facility perimeter protection tool comprising a combined detection facility consisting of a barrier, a radio beam detection facility, a vibration detection facility, a television monitoring device, cable power and low-current networks, is intended for constructing long, closed boundaries of facility perimeter protection. This tool is distinguished by the fact that it is equipped, on the outside, with a warning fence, in the form of a single-row mesh fence on metal load-bearing racks installed in the ground, and on the inside, with an engineering barrier, in the form of a single-row mesh fence with a visor on metal racks installed in soil equipped with four rows of a spiral safety barrier made of reinforced barbed tape. The barrier of the combined detection means is made in the form of a single-row lattice fence on metal support racks installed in the ground.

The transparency of the mesh and trellised barriers provides the ability to view the approaches to the protected area from the facility and use weapons to repel an external attack.

This tool allows you to delay the intruder for a time sufficient for the arrival of the response forces to the place of violation on the perimeters of large objects.

Description

The proposed utility model relates to technical means of protecting the perimeters of objects, and can be used for physical protection and signaling blocking of the perimeters of objects and extended borders on plain and rough terrain.

Known technical means of protecting the perimeters of objects - means of detection based on different physical principles of operation (vibration, triboelectric, capacitive, fiber), containing a barrier (mesh, trellis, brick or reinforced concrete), which is a physical barrier that creates a delay in unauthorized entry into the territory of the object. To ensure signaling blocking, sensitive elements of these detection tools are placed on the fence.

Signs of analogues that match the features of the proposed utility model:

1. The presence of a fence on which the sensitive elements of the detection means are located.

The disadvantages of these devices are:

1. The presence of only one obstacle, which is a physical barrier, which creates a delay for unauthorized entry into the territory of the object, which does not delay the intruder for a time sufficient for the arrival of response forces to the place of violation on the perimeters of long objects.

2. The opacity of the fence (brick, reinforced concrete), which excludes the possibility of viewing the approaches to the protected area from the territory of the facility and the use of weapons to repel an external attack.

As a prototype, a combined detection means is selected, which contains vibration detection means, radio-beam detection means, a television monitoring device, cable power and low-voltage networks, which are structurally located on a reinforced concrete fence. ("Combined detection tool". Application No. 2007107718 of 02.03.2007).

The functioning of the combined detection means is based on the formation of detection zones by each means of detection, at the intersection of which an intruder or a group of intruders transmits a response signal to the information collection and processing system.

Vibration detection means creates a detection zone on a mesh fence located at the top of the reinforced concrete fence.

The radio-beam detection means creates a detection zone from the upper part of the barrier to the surface of the earth, in order to prevent overcoming of the barrier from above or undermining under a reinforced concrete fence.

The width of the detection zone is (5 ... 6) m.

Signs of an analogue that match the features of the proposed utility model:

1. The presence of the fence, on which are located: vibration detection means, radio-beam detection means, television control device, cable power and low-current networks.

The disadvantages of this prototype device include:

1. The presence of only one obstacle, which is a physical barrier, which creates a delay for unauthorized entry into the territory of the object, which does not delay the intruder for a time sufficient for the arrival of response forces to the place of violation on the perimeters of long objects.

2. The opacity of the reinforced concrete fence, which excludes the possibility of viewing the approaches to the protected area from the territory of the facility and the use of weapons to repel an external attack.

The objective of the utility model is to create a combined means of protecting the perimeters of objects, which would eliminate the above disadvantages.

The technical result obtained in the implementation of the utility model is to ensure that the intruder is delayed for a time sufficient for the response forces to arrive at the site of violation on the perimeters of large facilities, the ability to view approaches to the protected area from the facility’s territory and use weapons to repel an external attack.

In the proposed combined facility perimeter security facility, in addition to the combined detection facility containing a fence, a warning fence and an engineering barrier have been introduced, which are physical barriers that create an additional delay for unauthorized entry into the facility, which allows the offender to be detained for a significantly longer time.

2. The transparency of the mesh and trellised barriers provides the ability to view the approaches to the protected area from the facility and use weapons to repel an external attack.

The utility model allows you to:

1. To detain the intruder for a time sufficient for the arrival of response forces to the place of violation on the perimeters of long-range objects.

As a mesh web 29, a welded, galvanized mesh of the SSCP type is used. The mesh web 29 is attached to the support legs 30 with washers, bolts and trims. Bearing racks 30 are made of square pipe (60 60) mm. An engineering obstruction has a height of 3.5 meters, from ground level, and unfolds up to 250 meters in length. The build-up is ensured by combining the obstacles in series with each other to organize an extended, closed line of guard of the perimeter of the object.

Due to the significant cutting effect and springing properties, the spiral safety barriers 26 of the engineering barrier are an especially insurmountable physical obstacle due to their volumetric design.

The combination means for protecting perimeters of objects described above are used as follows:

Prepare a combined security equipment for operation. Carry out an external inspection of the equipment for proper installation and reliability of electrical circuits when the power is off. The power of the combined detection means is turned on and the health of its equipment is monitored. To check the operability of the combined detection means, control actions are made by crossing the detection zone of the radio beam means by people in any three parts of the protection zone, with the simulation of destructive effects on the trellised section 11.

Use a combined security measure as follows:

The combined detection means is connected to a system for collecting and processing information and organizes round-the-clock duty of shift operators at the control panel of the system. The functioning of the combined detection means is based on the formation of detection zones by each means of detection, at the intersection of which an intruder or a group of intruders transmits a response signal to the information collection and processing system. The radio-beam detection means creates a detection zone between the warning and trellised boom of the combined detection means, in the exclusion zone 7, in a vertical plane, from the top of the trellised boom to the ground level. Detection zone width - (5 ÷ 6 ) m. Vibration detection means creates a detection zone on the trellised sections 11 of the fence.

After overcoming the warning fence, the intruder enters the detection zone of the radio beam detection means. The intersection by a person of the detection area of the radio beam means modulates the microwave signal at the input of the receiving unit 3. The receiving unit 3 of the radio beam detection means analyzes the amplitude and time characteristics of the received signal and, if they match the “intruder” model embedded in the processing algorithm, generates a response signal

and issues it via the communication cable 13 to the peripheral controller 21, in the form of opening normally closed relay contacts. The response signal of the radio-beam detection means from the peripheral controller 21 is supplied via the trunk cable 17 to the information collection and processing system.

When you try to climb through the trellised section 11, and deformation or destruction of its canvas by the intruder, the deformation and vibrations of the trellised section 11 are transmitted to the cable sensitive element 6 of the vibration detection means. The deformation and vibration of the cable sensing element 6 cause the appearance of electrical signals (due to the triboelectric effect) at its output. The electrical signals coming from the cable sensing element 6 through the connecting cable 10 to the processing unit 25 are amplified, filtered and processed by the processing unit 25 so as to distinguish, in accordance with the distinguishing features, the signals initiated by the action of the intruder on the trellised fence. The processing unit 25 provides a response signal through the communication cable 24 to the peripheral controller 21, in the form of opening normally closed relay contacts. The response signal of the vibration detection means from the peripheral controller 21 is supplied via the trunk cable 17 to the information collection and processing system. When a response signal from the combined detection means appears, the television control device transmits video information from the alarm section to the information collection and processing system, which allows the system operator to objectively evaluate the alarm situation.
