Definitions

  • the present invention refers to a perimetral protection apparatus, particularly for anti-break-in systems.
  • protection apparatuses feature the use of transmitter and receiver devices, positioned so as to create an electronic barrier by means of light, laser, infra-red or micro-wave beams.
  • the barrier is able to indicate that it has been crossed.
  • a category of electronic barriers exists that is used in alarm systems and is normally fitted on windows and/or doors, able to send an alarm signal to a break-in alarm unit in the event of the barrier being crossed by an intruder.
  • a common configuration is that which, on a first column fastened to a window or door jamb, infra-red transmitters are fitted that send a continuous and modulated beam to infra-red receivers located on a second column fastened to the opposite window or door jamb. Crossing the opening causes the interruption of one or more beams, which fail to reach their respective receivers.
  • the receivers are connected to an alarm unit to which they send a break-in signal.
  • the number of transmitters and corresponding receivers substantially depends on the amount of security required according to the height of the opening to be protected.
  • Another embodiment option envisages the use of suitable reflecting devices.
  • the infra-red transmitters and receivers are both located on a first column, while the reflecting devices are located on a second column.
  • a first limit relates to the problems which the triggering of a security system created using such devices can cause due to the accidental interruption of the electronic barrier beams by a person inside the area to be protected.
  • the owner could decide to switch on the security system while remaining inside the house and deciding to keep the windows open. In this case, if the owner leans out of the window, the alarm will accidentally trigger.
  • a further limit concerns the limited autonomy of the electronic barriers in the event of these being battery-powered, such units being commonly used because they are easy to install.
  • the main aim of the present invention is to eliminate the above drawbacks of the known technique by excogitating a perimetral anti-break-in protection apparatus that ensures the greatest freedom of movement to persons being inside the protected rooms.
  • another purpose of the present invention is to achieve low energy consumptions, thus ensuring high autonomy when using the apparatus.
  • Another purpose of the present invention is to achieve the previous aims with a simple structure, of relatively practical implementation, safe use and effective operation, as well as of a relatively low cost.
  • a perimetral protection apparatus particularly for anti-break-in security systems, comprising an electronic barrier that can be positioned near an opening located between a first area and a second area and provided with at least one sensor for detecting the transit of a person or object, characterised by the fact that it comprises means for determining the direction of transit through said electronic barrier.
  • the perimetral protection apparatus particularly for anti-break-in systems, generally designated by reference numeral 1, comprises an electronic barrier 2, which can be positioned near an opening located between a first area and a second area.
  • the electronic barrier 2 comprises a plurality of sensors for detecting the transit of a person or object which can be installed on at least two modules fastened along the perimeter of the opening.
  • Each sensor consists of a transmitter device 3, arranged on a transmitter module 5, and of a receiver device 4, arranged on a receiver module 6.
  • the transmitter module 5, in actual fact, comprises a plurality of transmitter devices 3 able to transmit respective beams towards a plurality of receiver devices 4 fastened to the receiver module 6 to create a network of beams able to protect the opening.
  • the two modules consist of two columns that can be fastened to door and window jambs, to one of which is fastened a row of infra-red transmitters that send a continuous and/or modulated infra-red beam to respective infra-red receivers located on the other column.
  • Crossing the opening necessarily interrupts one or more beams, causing reception failure on the part of the infra-red receivers, which are able to send a signal of the interruption occurred.
  • the number of infra-red transmitters and relevant infra-red receivers substantially depends on the amount of security required according to the height of the opening to be protected.
  • the transmitter devices 3 and the receiver devices 4 can be fastened to only one transmitter and receiver module while a second reflecting module can be provided for reflecting the beams produced by the transmitter devices 3 to the receiver devices 4 so as to create a network of beams to protect the opening.
  • a characterising feature of the invention in question is that it comprises means for determining the direction of transit through the electronic barrier.
  • the means for determining the direction of transit comprise at least a second barrier 7 arranged sequentially with respect to the electronic barrier 2 along the direction of transit between the first area and the second area, so that the barriers can be crossed sequentially during the transit of a person or object from the first area to the second area, or vice versa.
  • the second barrier 7 preferably comprises a plurality of second sensors installed on the two modules 5 and 6 and arranged, together with the sensors of the electronic barrier 2, along the direction of transit between the first area and the second area.
  • the second sensors consist of transmitter devices 8 and receiver devices 9, fastened to the transmitter module 5 and receiver module 6 respectively and arranged along parallel rows with respect to the transmitter devices 3 and receiver devices 4 making the electronic barrier 2.
  • the means for determining the direction of transit include a control device connected to the sensors of the electronic barrier 2 and to the sensors of the second barrier 7.
  • the control device is a microprocessor electronic circuit, preprogrammed to define and detect a first crossing sequence of the electronic barrier 2 and of the second barrier 7 during crossing by a person or object from the first area to the second area, and to define a second crossing sequence of the electronic barrier 2 and of the second barrier 7 during crossing by a person or object from the second area to the first area.
  • the control device is also connected to an alarm unit. More specifically in the event of the control device detecting - during the crossing of the opening by a person or object - a first crossing sequence of the electronic barrier 2 and of the second barrier 7, then it sends an alarm signal to the alarm unit with consequent activation of break-in signalling systems.
  • a break-in is detected from an outer area, indicated above as first area, to an area inside a home, indicated as second area, and an alarm signalling system is activated which preferably features the use of an acoustic signal and/or the sending of signals to police stations or, more generically, to surveillance centres.
  • the perimetral protection apparatus 1 is able to recognize the direction of crossing of the opening by a person or object. This way, the alarm signal only triggers following access from outside towards the inside of a protected area by an intruder, and any accidental activation of the alarm system by a person inside the protected area is avoided.
  • the perimetral protection apparatus 1 features energy saving means that are particularly useful in case of battery-powered barriers. More specifically, the electronic barrier 2 and the second barrier 7 are normally deactivated, and can be activated by means of a starting sensor 10 sensitive to any nearby movement. In particular, the starting sensor 10 is turned in the direction of the first area so as to force the start of the electronic barrier 2 and of the second barrier 7 only if a movement is detected outside the second area to be protected, thus further reducing consumptions and avoiding starting caused by movements inside the second area to be protected. If, after a pre-set time lapse, the network of beams created to protect the opening is not interrupted, the energy saving means again deactivate the electronic barrier 2 and the second barrier 7.
  • the starting sensor 10 comprises serial connection to the infra-red transmitters and/or receivers of the two barriers so as to command their starting after a movement has been detected.
  • it can feature the connection of the starting sensor 10 to the control device, the processor of which is programmed to activate the sensors of the two barriers in response to a detection signal produced by the starting sensor 10.
  • this starting sensor 10 features passive infra-red beams and is distinguished by low energy consumption.
  • the use of means for the periodical activation of the electronic barrier 2 and of the second barrier 7 independently from the starting sensor 10 is envisaged.
  • a further amount of security of the apparatus 1 is ensured by suitably adjusting the starting and switching off time.
  • the processor of the control device is preferably programmed to carry out such periodical activation functions.
  • the direction of transit through the opening of a person or object is determined by means of the use of the sequence consisting of the electronic barrier 2 and of the second barrier 7.
  • the electronic barrier 2 and the second barrier 7 are deactivated.
  • the starting sensor 10 detects the movement and commands the starting of the barriers and, therefore, the emission and reception of beams by means of the respective transmitter and receiver devices.
  • the control device In the event of transit being detected from the first area to the second area to be protected caused by the interruption in sequence of the networks created by the electronic barrier 2 and the second barrier 7, the control device detects a first crossing sequence and sends an alarm signal to the alarm unit, with consequent activation of the break-in signalling systems.
  • a break-in is therefore detected, for example, from an outside area, indicated above as first area, to an area inside a home, indicated as second area, and an anti-break-in system alarm signal is triggered.
  • the control device In case of transit through the opening from the second area to be protected to a first area the control device detects a second crossing sequence and, consequently, no alarm signal is sent to the alarm unit.
  • the break-in signalling system is not in this case triggered and thus remains in standby. This way accidental activation is prevented of the signalling system due to an interruption in the infra-red beam network by a person who is already inside the area to be protected.
  • the energy saving means again deactivate the electronic barrier 2 and the second barrier 7.
  • the means for determining the direction of transit comprise at least one inside movement sensor 11 turned towards the second area to be protected and able to send a signal to a control device for deactivating the electronic barrier 2, thus preventing accidental activation by a person who is inside the area to be protected.
  • the means for determining the direction of transit also comprise at least one outside movement sensor 12 turned towards the first area and able to send a signal to the control device for activating the electronic barrier 2. This way, the detection of a movement by the outside movement sensor 12 starts the electronic barrier 2 for the protection of the opening and, consequently, for the protection of the second area to be protected against undesired break-in.
  • outside movement sensor 12 and the inside movement sensor 11 feature low energy consumption passive infra-red beams.
  • the electronic barrier 2 is connected to an alarm unit for the activation of an alarm signal. More specifically, in case the electronic barrier 2 detects crossing of the opening by a person or object, it sends a signal to the central and an alarm signal is triggered.
  • this second form of embodiment of the perimetral protection apparatus 1 features energy saving means.
  • the electronic barrier 2 is normally deactivated and can be activated through the outside movement sensor 12 for detecting movements in the first area.
  • the outside movement sensor 12 is turned in the direction of the first area so as to force the start of the electronic barrier 2 if a movement is detected outside the second area to be protected.
  • the use of means for the periodical activation of the electronic barrier 2 independently from the outside movement sensor 12 is envisaged.
  • a further amount of security is ensured by suitably adjusting the starting and switching off time.
  • the electronic barrier 2 In a normal situation of use of the apparatus 1, in the absence of movements outside the second area to be protected, the electronic barrier 2 is deactivated. In case of movement inside the first area, the outside movement sensor 12 detects the movement and sends a signal to the control device which commands the starting of the electronic barrier 2. Under this condition of the apparatus 1 the opening is protected by a network of infra-red beams and crossing the opening from the first area to the second area to be protected causes the signalling to the alarm unit and triggering of the break-in signalling system.
  • the inside movement sensor 11 If a person moves near the apparatus 1 from the inside of the second area to be protected, the movement is detected by the inside movement sensor 11, which sends a signal to the control device commanding the switching off of the electronic barrier 2, thus preventing any accidental triggering of the alarm signal.
