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.

Abstract
Description
- 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.
- To this end 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.
- Another important object of the invention is that 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.
- As is known, in today's society, the threats to which both people and property are exposed are multiple and varied. That is why both modern-day society and industry demand security systems that will allow them to protect, control and supervise their facilities in a simple and effective manner, both locally and remotely.
- In order to protect property and/or persons within a delimited zone, the first threat to be avoided are intrusion attempts.
- Furthermore, we can indicate that 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:
- ∘ Delimiting the confinement zone of the facility (define the perimeter).
- ∘ Guaranteeing a high level of security throughout the enclosure, providing the perimeter with detection zones that will alert us as to a possible intrusion.
- ∘ Visually controlling the entire perimeter zone, both locally and remotely.
- ∘ Controlling and supervising, both locally and remotely, the entire system implemented.
- ∘ Efficiently and simply managing the set of systems, guaranteeing quick and easy access to the information generated by said systems.
- In order to solve the problem of detecting intrusion attempts, sensors of different types and technologies are used in accordance with the facility to be protected and the type of intrusion to be avoided.
- Moreover, it should be taken into consideration that one of the main problems of current sensors is their performance in the presence of animal, plant or weather-related external phenomena, which give rise to a large number of "false alarms".
- Therefore, for example, 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.
- Furthermore, as is known, 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:
- ✔ Flexibility
- ✔ Lightness
- ✔ Immunity to electromagnetic disturbances
- ✔ Absence of interferences
- ✔ Easy repair in the event of an intentional cut
- ✔ Long distance to be covered
- Additionally, the installation of 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.
- Likewise and in accordance with the foregoing, reference can be made to the fact that there are currently a large variety and number of zones protected by simple security fencing based on a plurality of posts anchored to the ground and whereon metal mesh is arranged and fixed until covering the entire perimeter to be protected, such that said fencing provides a minimum degree of security on not having any minimum intrusion detection means, such that the control of the fencing can only carried out visually.
- Therefore, 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.
- With the aim of solving the aforementioned drawbacks, 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.
- Therefore, the present specification describes a device for detecting intrusion on security fences, whose security fences are of the type consisting of:
- ➢ a plurality of posts anchored to the ground, delimiting the security perimeter; and
- ➢ metal mesh fixed between the posts, having the corresponding wire tensioners;
- ➢ a plurality of multimodal fibre optic cables camouflaged with the metal mesh that forms the security fence, along the length thereof;
- ➢ a series of signal analyzers housed in tight casings, with which, at least, one pair of fibre optic cables is associated;
- ➢ a diversity of concentrators with technology similar to that of the signal analyzers, being equally housed in tight casings, with which, at least, one pair of fibre optic cables is associated and provided with a connectivity module;
- ➢ a communication line of the signal analyzers and of the concentrators laid along the perimeter to be protected; and
- ➢ a control centre with which the communication line communicates;
- such that the signal analyzers comprise:
- an electronic detection module having the corresponding electronic control unit and connections of the pairs of fibre optic cables and digital inputs and outputs;
- a data communication module with the corresponding control unit, communicated with the electronic detection module and with the adjacent analyzers and/or concentrator;
- a weather management module having the corresponding control unit, communicated with the data communication module, and which controls the weather control elements; and
- a power supply management module fed by the mains or by an alternative source and which supplies power to the different analyzer modules.
- Therefore, 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.
- Furthermore, 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.
- Therefore, in the event of a break in a multimodal fibre optic cable, 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.
- In order to supply power to the constituent elements of the signal analyzers and concentrators, along the security perimeter, the corresponding power source from the mains or from an alternative energy source, such as solar panels, is available.
- Likewise, 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.
- Likewise, 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.
- In short, 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%.
- As a complement to the description made below, and for the purpose of helping to make the characteristics of the invention more readily understandable, said description is accompanied by a set of drawings whose figures, by way of illustration and not limitation, represent the most characteristic details of the invention.

Figure 1 shows a view of a section of security fence wherein posts can be observed between which the corresponding metal mesh (not represented) is strung, wherein the plurality of multimodal fibre optic cables associated with the signal analyzers and concentrators are mounted and camouflaged, defining a redundant communication ring along the fence; -
Figure 2 shows a view of a schematic block diagram relating to the signal analyzers. -
Figure 3 shows a schematic view relating to the protection of a section of fence layout on both sides of a railway line. -
Figure 4 shows a view of a schematic block diagram relating to a concentrator, showing how it incorporates a technology similar to the signal analyzers in addition to having a connectivity module. - In view of the aforementioned figures and in accordance with the numbering adopted, it can be observed how 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 theposts 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. - These types of fences are widely known and, thus, for example, are installed as security fences in land communication routes such as roads, dual carriageways, motorways and railway lines. However, on lacking means for detecting possible actions on the fence for accessing the zone to be protected they do not adequately fulfil their function, such that, with the aim of solving this drawback, this specification describes a device for detecting intrusion attachable to said type of fences, which allows the detection of any intrusion action or destruction of the fence with practically a 0 % number of false alarms.
- Therefore, 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 ofsignal analyzers concentrators communication line 7 communicated with acontrol centre 8, whosecommunication line 7 may be based on a fibre optic cable. - The
signal analyzers concentrators tight casings 4 and with which the plurality offibre 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 aforementionedtight casings 4 that house the technology of the signal analyzers and the concentrators may be fixed to theposts 2 themselves. - The
signal analyzers concentrators tight casings 4, are fed by themains 9 laid out along the perimeter to be protected. Likewise, the analyzers and concentrators may be fed by means ofsolar panels 10. - Therefore, the plurality of multimodal fibre optic cables associated with the
signal analyzers concentrators - In order to adequately control the entire facility to be protected, which may encompass many kilometres in length, a
concentrator signal analyzers - Furthermore, making mention of
figure 1 of the drawings, it can be observed how fourfibre optic cables 3 are associated with the signal analyzers and with the concentrators forming a redundant ring that can encompass a length of 500 metres, such that in the event of any cut or breakage of one of these, the signal analyzer or concentrator with which it is associated will detect that an interruption has occurred in the data transmission, indicative of breakage, said information being communicated to thecontrol centre 8 and locating the exact point thereof. - As reflected in the plurality of
multimodal fibre optic 3 cables, 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 thecommunication line 7 connected to thesignal analyzers concentrators control centre 8. - Making mention of the technology of the
analyzers figure 2 of the drawings, these are based on: - ➢ an
electronic detection module 11 provided with the corresponding electronic control unit and, basically, with:- ✔
fibre optic connections 12 with capacity for eight detection rings based on redundant rings of pairs ofoptic fibre cables 3; and - ✔ digital inputs and outputs 13 for receiving commands or events, such as temperature and humidity, and actuating on other installed elements, such as, for example, video surveillance cameras, external lights, etc.
- ✔
- ➢ a
data communication module 14, provided with the corresponding control unit, communicated with theelectronic detection module 12, and with the adjacent signal analyzer and/or concentrator, and whosedata communication module 14 transmits:- ✔ the events that have occurred;
- ✔ the status of each signal analyzer or concentrator module; and
- all the data collected in the interior of the signal analyzer or concentrator (for example, temperature and humidity).
- ➢ a
weather management module 15, provided with the corresponding control unit, communicated with thedata communication module 14 and which controls theweather control elements 16 in the interior of thetight casing 4; and - ➢ a power
supply management module 17 fed by themains 9 or by the alternative power supply and which supplies power to theelectronic detection module 11, to thedata communication module 14 and to theweather management module 15. - As regards the technology of the
concentrators signal analyzers connectivity module 21 which enables communication with thecontrol centre 8 or other places such as alarm centres or infrastructure centres. - In this manner, a block diagram of a concentrator can be observed in
figure 4 and it can be observed how the connectivity module has a plurality ofoutputs 22 for communication and, likewise, the two-waydata transmission line 23 can also be observed, for example, with an alarm centre. - Therefore, in accordance with the foregoing, 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. - Additionally, at least one battery may be installed in each of the
tight casings 4 of thesignal analyzers concentrators - Furthermore, the
weather management module 15 controls theweather 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 thetight casings 4 when faced to fast falls and rises in temperature. - This execution is of great importance in places where sudden temperature changes occur, such as desert areas with temperature differences between day and night that vary from more than 65 °C to -20 °C, whose changes in temperature cause the components housed in the interior of the tight casings to stop functioning properly, such that, on being able to maintain the ideal temperature in the interior the components can function properly.
- Likewise, there may be respective vision cameras and/or lights associated with all or part of the
tight casings 4 that house the signal analyzers and the concentrators, allowing thecontrol centre 8 to visualise everything that occurs in the immediate surroundings thereof. - Furthermore,
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 thesignal analyzers concentrators cable 19 channelled beneath the railway line 18, withrespective switch boxes 20 of redundant fibre optic rings or loops 3' arrangements. Thus, it can be observed how eight breakage detection redundant loops or rings are associated to each concentrator and to each analyzer, although the number may vary. - In this manner, the
signal analyzers concentrators 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. - Thus, the security fences installed on both sides of the railway line 18 are arranged symmetrically and identically to each other.
- Likewise, it can be observed how the facility has the
corresponding power line 9 that feeds the signal analyzers and the concentrators, as well as thecommunication line 7 between the signal analyzers and concentrators, as well as with thecontrol centre 8. - Focusing on the fibre optic cable, we can indicate that it is sufficiently resistant not to break in the event of manipulation of the fence (blows, pulling, pushing), while the fence does not break or give, such that it breaks when it is either cut exerting an action intended to cut the mesh or breaks when the forces acting thereupon are already likewise breaking the mesh.
- Furthermore, with regard to camouflaging the fibre optic cable, it can be indicated that 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.
- Lastly, it should be noted that the tight casings that contain the elements relative both to the analyzers and to the concentrators have a microswitch for detecting that they have been opened, as a protection against possible sabotage.
