Definitions

  • the following invention as expressed in the title of this specification, relates to a device for detecting intrusion on security fences, whose security fences delimit a perimeter to be protected, with the object of detecting any attempt of intrusion or destruction of the fencing with absolute reliability and, additionally, detecting the specific site where it occurs, for which purpose the device is based on the constant monitoring of a plurality of optical signal transmission lines.
  • a significant advantage of the device is that it is immune to vibrations, strong wind, blows, noise and adverse weather conditions, including electrical discharges, avoiding false alarms.
  • the security fence includes, along its length, a plurality of multimodal fibre optic cables camouflaged by the metal mesh that configures the perimeter to be protected, whose plurality of multimodal fibre optic cables are assembled in association with a series of signal analyzers and concentrators, said concentrators being based on the same technology as the signal analyzers with the addition of a connectivity module for communicating with a control centre or other places, such that the plurality of fibre optic cables form a redundant communication ring to guard against eventual breaks in the multimodal fibre optic cable.
  • the device for detecting intrusion may be installed both on security fences to be installed and those already existing formed by a plurality of posts anchored to the ground and between which mainly, simple-torsion metal mesh is arranged and fixed, although other types of metal mesh may be used and fences which lack added elements that provide authentic security.
  • This specification describes a device for detecting intrusion on security fences, which is applicable for assembling both on security fences to be installed and those already existing consisting of a plurality of posts anchored to the ground and whereon metal mesh is arranged and fixed for protecting long perimeter layouts, enclosures and roads that must have a certain level of security and whose detection device is especially applicable to the protection of long-distance and high-speed railway line layouts.
  • the first threat to be avoided are intrusion attempts.
  • perimeter protection solutions is the name given to the set of systems and equipment which, acting in a coordinated manner, minimise the possibility of intrusion in the confinement zone, protecting the persons and/or property located inside the perimeter.
  • Perimeter protection solutions are based mainly on:
  • sensors of different types and technologies are used in accordance with the facility to be protected and the type of intrusion to be avoided.
  • sensors based on microwaves or microphonic cables are highly sensitive to external phenomena, such that in order to discriminate between a real alarm and a false alarm they use complex algorithms that analyse and discriminate the signals obtained by the sensor in order to compare it with a pattern and ascertain whether or not it is a real alarm.
  • the signals are analysed according to their intensity or vibration pattern, which requires onsite calibration in order to adapt the sensor to the terrain and environmental conditions of the site where it will be installed. Even so, the rate of false alarms can be high.
  • optical fibre is immune to weather conditions and is not affected by the action of external elements, so that once installed it does not require calibration or learning patterns, endowing the installation with a series of advantages, such as:
  • optical fibre is extremely simple and fast, as it is stapled to the simple-torsion mesh and it cannot be sabotaged, since it cannot be cut to execute a bypass.
  • this type of fencing is frequently used in the protection, for example, of land communication routes such as roads, motorways and railways, with the drawback of not being able to detect any type of intrusion other than visually, due to which, in practice, it lacks security and, additionally, has the added drawback that this type of fencing covers large extensions, due to which it is becoming increasingly necessary to have a stricter control with which to detect any intrusion at the time and place where it occurs.
  • the present specification describes a device for detecting intrusion on security fences, which is especially applicable for assembling on already existing security fences for protecting communication routes, although, obviously, it may also be applied to other types of security fences, such that the device object of the invention, of low economic cost, makes it possible to detect the site where the intrusion occurs with the significant advantage of having, practically, 0 % of false alarms, which is a very significant advantage.
  • the present specification describes a device for detecting intrusion on security fences, whose security fences are of the type consisting of:
  • a data flow is transmitted via the plurality of multimodal fibre optic cables, whose mere interruption is indicative of a break in the multimodal fibre optic cable and, consequently, of intrusion.
  • the weather control elements are defined by a temperature sensor and a humidity sensor associated with a resistor, with an automatic internal pressure relief valve and with a fan, controlling fast rises and falls in temperature in the interior of the tight casing with the object of maintaining an adequate temperature in order to ensure the proper operation of the elements housed inside the tight casings.
  • a concentrator will be installed every certain number of signal analyzers, which is the signal interface between the entire sector of signal analyzers associated therewith and the control centre or place of communication.
  • the signal analyzer or concentrator with which it is associated detects the interruption of the flow and, upon being communicated to the control centre, the site of interruption of the data transmission flow due to the breakage of the multimodal fibre optic cable is determined such that it is possible to act accordingly.
  • the corresponding power source from the mains or from an alternative energy source, such as solar panels, is available.
  • At least one battery may be installed in each of the tight casings of the signal analyzers and of the concentrators, so that, in the event of a failure in the power mains or alternative energy source, a power supply is available which continues to function adequately, also allowing said supply to come from individual solar panels per each analyzer, in those cases where it is deemed necessary.
  • respective lights and/or vision cameras may be installed in association with all or part of the tight casings wherein the signal analyzers and concentrators are housed, enabling visual control over the immediate surroundings within a certain action radius.
  • a significant advantage is that, due to the plurality of multimodal fibre optic cables, whose mechanical resistance has been designed so as to break in accordance with an intrusion condition, a data flow whose mere interruption is indicative of a break in the multimodal fibre optic cable and, consequently, of intrusion, is transmitted, i.e. it does not analyse the signal transmitted, allowing the number of false alarms to be reduced practically to 0%.
  • the security fence 1 is of the type of widely known fences consisting of a plurality of posts 2 anchored to the ground between which metal mesh, not represented, is strung, fixed to the posts 2 with the corresponding wire tensioners delimiting the security perimeter and which, in principle, lack any means for detecting possible actions therein, such as cuts to access the protected zone.
  • the device for detecting intrusion is based on a plurality of multimodal fibre optic cables 3 camouflaged with the metal mesh that constitutes the security fence, along its entire length, as well as a series of signal analyzers 5, 5', 5", 5"',... and concentrators 6, 6', 6", 6"',... whose concentrators are based on the same technology as the signal analyzers, in addition to being connected by means of a communication line 7 communicated with a control centre 8, whose communication line 7 may be based on a fibre optic cable.
  • the signal analyzers 5, 5', 5",... and the concentrators 6, 6', 6",... will be housed inside respective tight casings 4 and with which the plurality of fibre optic cables 3 is associated for the continuous monitoring thereof in order to control the continuous transmission of optical signal since, otherwise, i.e. lack of signal transmission, it will be indicative of a cut or break of the fibre optic cable.
  • the aforementioned tight casings 4 that house the technology of the signal analyzers and the concentrators may be fixed to the posts 2 themselves.
  • the signal analyzers 5, 5', 5",... and the concentrators 6, 6', 6",... housed inside the tight casings 4, are fed by the mains 9 laid out along the perimeter to be protected. Likewise, the analyzers and concentrators may be fed by means of solar panels 10.
  • the plurality of multimodal fibre optic cables associated with the signal analyzers 5, 5', 5", 5"',... and the concentrators 6, 6', 6", 6"',... define corresponding redundant communication rings along the security fence 1, detecting the site of a possible intrusion or destruction of the fence.
  • a concentrator 6, 6', 6", 6"',... will be installed every certain number of signal analyzers 5, 5', 5", 5"',...
  • a data flow is transmitted, whose mere interruption is indicative of breakage and, consequently, of intrusion, i.e. it does not analyse the signal obtained, but rather the signal analyzers and the concentrators with the control electronics associated therewith, only detect whether or not the data flow arrives, communicating any incident via the communication line 7 connected to the signal analyzers 5, 5', 5",... and with the concentrators 6, 6', 6",... to the control centre 8.
  • the technology of the concentrators 6, 6', 6",... corresponds to the technology related to the signal analyzers 5, 5', 5",... in addition to a connectivity module 21 which enables communication with the control centre 8 or other places such as alarm centres or infrastructure centres.
  • FIG. 4 a block diagram of a concentrator can be observed in figure 4 and it can be observed how the connectivity module has a plurality of outputs 22 for communication and, likewise, the two-way data transmission line 23 can also be observed, for example, with an alarm centre.
  • the electronic detection module 11 monitors the continuity of the eight fibre optic loops, such that each fibre optic line extends along a maximum two-way layout of one thousand metres, offering protection, on being a loop or ring of 500 linear metres, with two fibre optic lines.
  • At least one battery may be installed in each of the tight casings 4 of the signal analyzers 5, 5', 5", 5"',... and of the concentrators 6, 6', 6", 6"',..., which will make it possible to maintain the power supply under possible circumstances in which power is not supplied by the mains or solar panels.
  • the weather management module 15 controls the weather control elements 16, which can be based on a temperature and humidity sensor associated with a resistor and a fan, making it possible to maintain an adequate temperature in the interior of the tight casings 4 when faced to fast falls and rises in temperature.
  • control centre 8 may visualise everything that occurs in the immediate surroundings thereof.
  • figure 3 of the drawings represents a possible layout protection diagram related to a sector section, such that we can observe how the corresponding security fence 1 and 1' is installed on both sides of a railway line 18, such that each of the signal analyzers 5, 5', 5",... and of the concentrators 6, 6', 6",... is connected by means of a cable 19 channelled beneath the railway line 18, with respective switch boxes 20 of redundant fibre optic rings or loops 3' arrangements.
  • switch boxes 20 of redundant fibre optic rings or loops 3' arrangements.
  • the signal analyzers 5, 5', 5",... and the concentrators 6, 6', 6",... are installed on only one side of the layout, in the practical example on the security fence 1, and the associated fibre optic cables 3-3' forming a breakage detection redundant loop are arranged such that two loops or rings are arranged on both sides and on the security fence 1' on the other side of the railway line 18, equally, the associated switch boxes 20 have two loops or rings on both sides, whereby each signal analyzer and each concentrator controls eight zones of up to 500 metres.
  • the security fences installed on both sides of the railway line 18 are arranged symmetrically and identically to each other.
  • the facility has the corresponding power line 9 that feeds the signal analyzers and the concentrators, as well as the communication line 7 between the signal analyzers and concentrators, as well as with the control centre 8.
  • the appearance of the outer sheath of the fibre i.e. diameter and appearance as well as touch, are identical to those of the wire rods that compose the fence and, additionally, the colour is also the same as that of the wire rods. That is, if the wire rods are galvanised, fibre cable whose outer appearance is that of the galvanised wire rods is laid and, if the wire rods are painted, the fibre cable is the same colour as that of the wire rods.
