Description

Intrusion detection device

[0001] The present invention relates to an unauthorized intrusion detection device, and more specifically, to provide an unauthorized intrusion detection device that can detect unauthorized intrusion by being installed in a designated location or position, such as a barbed wire fence.

[0002] Typically, industrial sites such as steel mills, power plants, chemical plants, tunnels, etc., as well as barbed wire fences and security facilities, have barbed wire mesh (fences) installed to prevent unauthorized entry by people from the outside, or cameras installed to film unauthorized entry.

[0003] However, this method suffers from the difficulty of immediately responding to cuts or deformations in the wire mesh, hindering its essential function of detecting unauthorized intrusions. Furthermore, industrial sites with large facilities and critical security facilities require the installation of numerous cameras, heat sensors, and other barriers to detect (monitor) external intrusions. This increases operational costs, particularly when considering operational efficiency. In particular, the frequent breakdown of numerous detection devices, increased maintenance costs, and functional degradation due to malfunctions are problematic.

[0004] Meanwhile, installing a separate detection device can cause interference with existing equipment and make it unsuitable for use in confined industrial settings. Fence monitoring, for example, can be problematic due to interference from natural obstacles like trees, heavy rain, or nighttime conditions, making stable detection impossible.

[0005] Fig. 1 is a front view illustrating the configuration of an unauthorized intrusion detection device according to the prior art. Referring to Fig. 1, the unauthorized intrusion detection device according to the prior art includes a plurality of posts (10), a plurality of ropes (blocking ropes, 20), and a plurality of sensors (40). Here, the ropes (20) are connected to the posts (10). The ropes (20) are arranged so as to block the section between the posts (10) to prevent unauthorized intrusion, and the sensors (40) are connected to the ropes (20) to detect unauthorized intrusion.

[0006] In the conventional intrusion detection device, the ropes (20) may be deformed (sagging, etc.) due to temperature changes, self-weight, etc., and the spacing between the ropes (20) may be significantly changed due to such deformation, etc. In addition, in the conventional intrusion detection device, the ropes (20) are easily deformed as the interval between posts (10) is long. Therefore, if the construction section is long, it is difficult to maintain the ropes (20) in a straight line by dividing the long-distance construction section into short-distance unit sections for installation, or configuring the ropes (20) to be able to apply strong tension. Here, applying strong tension to the ropes (20) may cause problems such as deformation (bending, etc.) of the posts (10) and enlargement of the means for applying tension.

[0007] Meanwhile, in the case of a conventional intrusion detection device, even if the construction section is a short distance, the sensors (40) must be connected to each end of the ropes (20), and as a result, a large number of sensors (40) must be provided. As the number of sensors (40) is large, there is a problem in that there is a high risk of failure and considerable maintenance is required.

[0008] As related patent documents, reference may be made to Korean Patent Publication No. 10-2009-0097258 (September 16, 2009), Korean Patent Registration No. 10-1420596 (July 21, 2014), Korean Patent Registration No. 10-1575843 (December 22, 2015), Korean Patent Registration No. 10-1606203 (March 25, 2016), and Korean Patent Publication No. 10-2023-0049457 (April 13, 2023).

[0009] The purpose of the present invention is to provide an unauthorized intrusion detection device that can immediately detect changes in the position of ropes and cutting, etc. that occur during an unauthorized intrusion process by pulling ropes (blocking ropes) in a designated direction to maintain them in a tensile state so as to apply a weak tension to the ropes.

[0010] Another object of the present invention is to provide an unauthorized intrusion detection device capable of detecting position changes and cuts in a plurality of ropes connected with weak tension using a minimum number of detection units without strong tension over a long distance.

[0011] The problems to be solved are not limited to these, and other problems not mentioned will be clearly understood by those skilled in the art from the description below.

[0012] According to an embodiment of the present invention, an unauthorized intrusion detection device (100) may be provided, including: a plurality of main bodies (110) installed at a selected location in a detection area; a plurality of blocking ropes (120) arranged to connect the main bodies (110) to each other in a horizontal direction but to be spaced apart from each other in a vertical direction by a predetermined distance to prevent unauthorized intrusion; and a detection unit (130) formed to pull the plurality of blocking ropes (120) in a designated direction to maintain a tensile state so as to detect a change caused by shaking or cutting of the blocking ropes (120) during an unauthorized intrusion process.

[0013] The above detection unit (130) may include a detection rope (131) formed so as to be able to horizontally connect the upper portions of the main body (110); a connecting member (132) formed so as to connect the blocking rope (120) and the detection rope (131) to each other so as to pull the blocking rope (120) in a designated direction to maintain it in a tensile state; and a detection means (133) formed so as to detect the shaking or positional change of the detection rope (131) caused by the shaking or cutting of the blocking rope (120) so as to confirm unauthorized intrusion.

[0014] The above connecting member (132) is characterized in that it is formed integrally so that one end is connected to the blocking rope (120) located at the top, the middle end circulates around the outside of the rotating body (131a) formed so that it can rotate around the detection rope (131), and the other end can be connected to the blocking rope (120) located at the bottom.

[0015] The above detection means (133) is characterized by including a control unit for remembering a reference data value of a normal state in which the blocking rope (120) is not shaken, and comparing the data value with a data value for a shake or position change of the detection rope (131) caused by an unauthorized intrusion or cutting of the blocking rope (120), and determining that an unauthorized intrusion has occurred if the difference exceeds the error range.

[0016] The solution to this problem will be made more concrete and clear through the examples, drawings, and other materials described below. Furthermore, various solutions other than those mentioned below may be presented.

[0017] The present invention has the effect of enabling prompt follow-up measures to be taken by immediately detecting and sensing the shaking or cutting state of the blocking ropes that occur during an unauthorized intrusion process by pulling the blocking ropes in a designated direction with a weak tension and maintaining them in a tensile state.

[0018] The present invention can detect the shaking or cutting state of blocking ropes in a long-distance section using a minimum detection unit, thereby eliminating the inconvenience of maintenance that occurs when installing complex equipment and a large number of sensors as in the past, and has the effect of reducing economic costs.

[0019] The present invention has the effect of preventing deformation due to strong tension occurring in blocking ropes in long-distance sections, thereby improving durability and service life.

[0020] The effects of the invention are not limited thereto, and other effects not mentioned will be clearly understood by those skilled in the art from this specification and the attached drawings.

In addition, when it is said that a part is connected (or coupled) to another part, this includes not only cases where it is directly connected (or coupled), but also cases where it is indirectly connected (or coupled) with another part in between.

[0036] Meanwhile, the size, shape, and line thickness of components in the drawing may be somewhat exaggerated for ease of understanding.

[0037] Embodiments of an unauthorized intrusion detection device according to the present invention are illustrated in FIGS. 2 to 7. FIGS. 2 and 3 illustrate the configuration and operation of an unauthorized intrusion detection device according to one embodiment of the present invention. In addition, FIGS. 4 to 7 illustrate the configuration of an unauthorized intrusion detection device according to several other embodiments of the present invention. An unauthorized intrusion detection device according to embodiments of the present invention can prevent and detect unauthorized intrusion.

[0038] Referring to FIG. 2, an unauthorized intrusion detection device (100) according to one embodiment of the present invention includes a plurality of main bodies (110) arranged at a predetermined interval so as to be horizontally spaced from each other in a detection area (a construction section where an unauthorized intrusion detection device is installed to prevent and detect unauthorized intrusion); a plurality of blocking ropes (120) arranged to connect the main bodies (110) to each other in the horizontal direction and block between the main bodies (110) to prevent unauthorized intrusion; and a detection unit (130) that maintains the blocking ropes (120) in a taut state, detects a change in the taut blocking ropes (120), and determines whether an unauthorized intrusion has occurred based on the detected change.

[0039] The main bodies (110) are provided at each selected location (pre-set location) in the detection area. The placement location of the main bodies (110) may be determined according to the length, area, etc. of the detection area. For example, the main bodies (110) may be provided as posts. In addition, the posts may be installed vertically on the floor of the detection area.

[0040] Depending on implementation conditions, etc., an unauthorized intrusion detection device (100) according to one embodiment of the present invention (hereinafter, the designation of drawing symbols is omitted) may be installed in front or behind an existing barbed wire fence or wire mesh along the length of the existing barbed wire fence or wire mesh to double prevent or detect unauthorized intrusion together with the barbed wire fence or wire mesh.

[0041] The blocking ropes (120) are arranged at a predetermined interval so as to be spaced apart from each other in the vertical direction (up and down) so as to block the main bodies (110). The main bodies (110) connected to each other by these blocking ropes (120) are provided with guides (111) extending vertically on their inner sides facing each other, and each of the blocking ropes (120) is connected to a movable body (121) that can move vertically along the guides (111) on both sides facing each other at both ends. By moving the blocking ropes (120) in the vertical direction, the vertical position of each of the blocking ropes (120) and the vertical interval between the blocking ropes (120) can be adjusted to a state required for preventing unauthorized intrusion.

[0042] The guides (111) may be provided as guide rails, etc. Each of the moving bodies (121) may include a moving element that moves according to the guidance of the guides (111), and a position fixing element that performs position fixing and releasing of the moving element with respect to the guides (111). The moving elements may have bearings, rollers, wheels, etc. The position fixing elements may have bolts, clamps, etc. By moving the moving elements to a required position (designated position) along the guides (111) and fixing the positions of the moved moving elements by the position fixing elements, the vertical position of each of the blocking ropes (120) and the vertical spacing between the blocking ropes (120) can be fixed to a required state.

[0043] The blocking ropes (120) can be provided to have the required characteristics (length, material, etc.) according to the length, area, etc. of the detection area. Each of the blocking ropes (120) is connected to a tension regulator (122) at both ends to maintain or adjust the tension of the blocking rope (120) at a required level. Each of these tension regulators (122) is provided between the blocking rope (120) and a moving body (121). Each of the moving bodies (121) is connected to the tension regulator (122). Accordingly, the moving bodies (121) are connected to both ends of the blocking ropes (120) through the tension regulators (122).

[0044] The tension regulators (122) can be configured to manually or automatically maintain or adjust the tension of the blocking ropes (120) using turnbuckles, springs, etc., respectively.

[0045] The detection unit (130) maintains the blocking ropes (120) in a tensile state so that changes (cutting, shaking, bending, etc.) in the blocking ropes (120) that may occur during an unauthorized intrusion can be immediately detected. In the conventional technology, both sides of the rope (blocking rope) must be pulled in the longitudinal direction to maintain strong tension, so that a lot of load and deformation occur depending on the length of the rope. However, in the unauthorized intrusion detection device according to one embodiment of the present invention, even if the blocking ropes (120) maintain weak tension, the detection unit (130) pulls the blocking ropes (120) in a designated direction to maintain the blocking ropes (120) in a tensile state, so that changes in the blocking ropes (120) that occur during an unauthorized intrusion can be immediately detected.

[0046] The detection unit (130) includes a detection rope (131) that horizontally connects the main bodies (110) above the uppermost blocking rope among the blocking ropes (120); at least one connecting member (132) that pulls the blocking ropes (120) in a designated direction (a direction set in advance) with respect to the detection ropes (131) to keep the blocking ropes (120) in a tensile state; and a detector (133) that detects a change in the detection rope (131) according to a change in the state of the blocking ropes (120) and determines whether there is an unauthorized intrusion based on the detected change.

[0047] The detection rope (131) may be provided with a flexible material. The detection rope (131) may be connected to the upper portions of the main bodies (110). The main bodies (110) connected to each other by the detection rope (131) may be mounted on opposite inner sides so that the opposite ends of the detection rope (131) can be easily detachably attached. The opposite ends of the detection rope (131) are attached to the main bodies (110) by mounting elements (131b), respectively.

[0048] Each mounting element (131b) is provided between the main body (110) and the detection rope (131). Each mounting element (131b) may be configured to detachably connect the detection rope (131) to the main body (110) by a connection method such as a bolt connection or a flange connection. In addition, each of the mounting elements (131b) may be configured to manually or automatically maintain or adjust the tension of the detection rope (131) using a turnbuckle, a spring, or the like.

[0049] The connecting member (132) can not only keep the blocking ropes (120) in tension by connecting the detection ropes (131) to the blocking ropes (120) by pulling the blocking ropes (120) upward with respect to the detection ropes (131) using its own fixed length, but can also support the blocking ropes (120) to prevent the blocking ropes (120) from sagging and prevent the vertical gap between the blocking ropes (120) from widening significantly due to external force.

[0050] A plurality of connecting members (132) are provided. The number of connecting members (132) is the same as the number of blocking ropes (120), and the upper parts are all connected to the detection ropes (131), and the lower parts are each connected to different blocking ropes (120). The connecting members (132) can be arranged at intervals so as to be spaced apart from each other along the length direction of the blocking ropes (120).

[0051] The number of connecting members (132) may exceed the number of blocking ropes (120). In this case, at least some of the blocking ropes (120) may be connected to a plurality of connecting members (132) and held in tension by the plurality of connecting members (132). For example, the connecting members (132) may be provided as wires, such as rods or wires.

[0052] Each of the connecting members (132) is connected to the detection rope (131) through a first moving member (132a1) and to the blocking rope (120) through a second moving member (132a2). The first moving member (132a1) is provided to be movable along the detection rope (131), and each of the second moving members (132a2) is provided to be movable along the blocking rope (120). By means of the first moving members (132a1) and the second moving members (132a2), the connecting members (132) can be easily moved, thereby adjusting the arrangement position of each of the connecting members (132) and the arrangement interval between the connecting members (132).

[0053] Each of the connecting members (132) has an upper portion connected to a first moving member (132a1) and a lower portion connected to a second moving member (132a2). The first moving member (132a1) may be configured to move along the detection rope (131) using a roller, a tube, or the like. In addition, the first moving member (132a1) may have a configuration in which its position is fixed or released from fixation with respect to the detection rope (131) using a bolt, a clamp, or the like. Each of the second moving members (132a2) may be configured to move along the blocking rope (120) using a roller, a tube, or the like. In addition, each of the second moving members (132a2) may have a configuration in which its position is fixed or released from fixation with respect to the blocking rope (120) using a bolt, a clamp, or the like.

[0054] The detector (133) detects (senses) the repulsive force of the detection rope (131) generated as the blocking ropes (120) change during the unauthorized intrusion process. The detector (133) may be equipped with a sensor having the characteristic of being able to immediately and accurately detect the amount of change (displacement) of the detection rope (131) due to the repulsive action of the detection rope (131) caused by the blocking ropes (120).

[0055] The detector (133) may be equipped with a charger and may be supplied with power through the charger, may be supplied with commercial power from an external source, or may be supplied with power using a solar panel (133a) and a self-generation function.

[0056] The change detected by the detector (133) is transmitted to the driver's room (control room) in real time to detect unauthorized intrusion. The detector (133) remembers the normal, unchanged state of the blocking ropes (120) as a reference data value, uses the change detected by the detector (133) as a detection data value, and compares the detection data value with the reference data value to determine whether there has been an unauthorized intrusion. For this purpose, the detector (133) may be equipped with a control unit.

[0057] The detector (133) can determine that an unauthorized intrusion has occurred if the detected data value is outside the error range as a result of comparing the detected data value with the reference data value. For such comparison operations, the control unit may be equipped with a central operation processing module.

[0058] The control unit of the detector (133) may set an error range so that the amount of change detected when a person or the like trespasses but when a slight vibration or wind acts on the blocking ropes (120) can be ignored in order to improve the accuracy of the judgment when determining whether or not there has been an unauthorized intrusion.

[0059] Meanwhile, the detector (133) may be equipped with a warning module, and when it is determined that an unauthorized intrusion has occurred, the warning module may be activated to visually (light) and / or audibly (alarm sound) warn that an unauthorized intrusion has occurred.

[0060] Referring to FIG. 3, in an unauthorized intrusion detection device according to one embodiment of the present invention, when the blocking ropes (120) maintained in a tensile state by the connecting members (132) are cut or shaken due to an unauthorized intrusion, the detection rope (131) changes by shaking or shaking in response to the change in the blocking ropes (120), and the detector (133) detects the unauthorized intrusion by detecting the amount of change in the detection rope (131). Therefore, follow-up measures against unauthorized intrusion can be quickly taken.

[0061] Several other embodiments of an unauthorized intrusion detection device according to the present invention will be described with reference to FIGS. 4 to 7.

[0062] The embodiment illustrated in FIG. 4 is different from the embodiment illustrated in FIG. 2 in that the connecting members (132) connecting the detection rope (131) to the blocking ropes (120) are configured differently. In the embodiment illustrated in FIG. 4, each of the connecting members (132) has its middle portion connected to the detection rope (131) via a rotating member (131a), and its opposite ends are connected to different blocking ropes (120), respectively. The rotating members (131a) are provided to be rotatable with respect to the detection rope (131). The rotating members (131a) may be provided as rollers, pulleys, or the like that are rotatable around the detection rope (131). Each of the connecting members (132) may have its middle portion hooked to the rotating member (131a), and its opposite ends may be connected to the blocking rope (120) via the second moving member (132a2) described above.

[0063] In the embodiment illustrated in FIG. 4, the connecting members (132) each connect the detection rope (131) to the two selected blocking ropes (120), so that even if either of the two selected blocking ropes (120) changes, the corresponding change can be transmitted to the detection rope (131) to cause the detection rope (131) to repel.

[0064] The embodiment illustrated in FIG. 5 differs from the embodiment illustrated in FIG. 2 or the embodiment illustrated in FIG. 4 in that the connecting members (132) are configured to have length-adjusting elements (132b). The lengths of the connecting members (132) of the embodiment illustrated in FIG. 5 can each be adjusted by the length-adjusting elements (132b). The connecting members (132) of the embodiment illustrated in FIG. 5 can be configured to be length-adjustable using turnbuckles, bolts and nuts, springs, and the like.

[0065] The embodiment illustrated in FIG. 6 is different from other embodiments in the position at which the detection rope (131) of the detection unit (130) is applied, etc. In the embodiment illustrated in FIG. 6, the detection rope (131) may be provided to horizontally connect the main bodies (110) to each other below the lowest blocking rope among the blocking ropes (120). In addition, the connecting members (132) may be provided to connect the detection rope (131) to the blocking ropes (120) so as to pull the blocking ropes (120) downward with respect to the detection ropes (131). The embodiment illustrated in FIG. 6 may be used when an obstacle such as a wall (A) exists.

[0066] The embodiment illustrated in FIG. 7 is different from other embodiments in the position at which the detection rope (131) of the detection unit (130) is applied, etc. According to the embodiment illustrated in FIG. 7, the detection rope (131) can be installed in front or rear of the blocking ropes (120), and the connecting members (132) can connect the detection rope (131) disposed in front or rear of the blocking ropes (120) to the blocking ropes (120). The embodiment illustrated in FIG. 7 can be used in cases where interference occurs between the detection rope (131) and / or the connecting members (132) and other structures (barbed wire, wire mesh, etc.) when the detection unit (130) is disposed above or below the blocking ropes (120).

[0067] While the present invention has been described above, it is not limited to the disclosed embodiments and accompanying drawings, and various modifications may be made by those skilled in the art without departing from the technical spirit of the present invention. Furthermore, the technical concepts described in the embodiments of the present invention may be implemented independently, or two or more may be combined.
