Definitions

  • the present invention relates to a remote alarm system, intended more particularly for users of public places and transport.
  • the main object of the present invention is therefore to remedy these drawbacks and, to do this, it relates to a remote alarm system which is essentially characterized in that it comprises individual portable transmitter devices with short range, which can be actuated manually in order to '' emit a predetermined alert signal, and a multiplicity of fixed receiving devices arranged at appropriate locations of a site to be protected, these receiving devices being able to receive the alert signal emitted by any of the portable devices finding within range and retransmitting the alert thus detected to intervention personnel.
  • the individual nature of the transmitting device thus guarantees a certain discretion and it is also immediately available since it is carried by the user, for example in the pocket or in a handbag.
  • Such a remote alarm system therefore represents additional security compared to the conventional means implemented by the public authorities.
  • the portable transmitter device is for single use and cannot be dismantled without destruction. In other words, it can only be used once, which considerably limits the possibilities of false alarms.
  • the portable transmitting device has an operating validity limited in time, which makes it possible to finance the installation and maintenance of the fixed equipment by the sole sale of the portable devices.
  • the portable transmitting device once actuated, has a limited duration of operation.
  • the remote alarm system further comprises at least one mobile receiving device, provided with a directing antenna, in order to make it possible to locate the transmitting device which has triggered the alarm.
  • the portable transmitter device consists of a small box containing a radio transmitter capable of being supplied from an autonomous energy source by means of a switch controlled by a button protruding from the surface of the housing.
  • the switch control button is normally covered by a protective cap made integral with the housing and which can only be detached from it by the rupture of a retaining lug.
  • the alarm cannot be triggered unexpectedly since it is first necessary to remove the protective cap by an irreversible voluntary action and only then to actuate the control button.
  • control button is of the push button type and includes a non-return system, so that it can be actuated only once.
  • the radio transmitter is associated with a modulator characterizing its validity date, which makes it possible to give each portable device a validity period limited in time taking account of the renewal rate judged necessary.
  • each portable device has an individual code sent at the same time as the alert signal, which makes it possible to possibly identify the person who triggered the alarm using a central file.
  • the remote alarm system essentially consists of individual portable transmitting devices 1, of the type of that shown schematically in FIG. 1, and of receiving devices 2, of the type of that shown schematically in FIG. 2, arranged at locations appropriate landlines of a site to be protected such as a public place, such as the metropolitan area.
  • a site to be protected such as a public place, such as the metropolitan area.
  • such fixed devices can not only be arranged in the corridors or stations, but also on board the transport trains.
  • the portable transmitter device 1 essentially consists of a modulator 3 and a radio transmitter 4, capable of being supplied from an autonomous energy source such as a battery 5, via a switch 6 with manual actuation, in order to emit a predetermined alert signal.
  • the radio transmitter 4 is associated with a transmission antenna 7 and it will preferably have a short range, for example a hundred meters.
  • the receiving device 2 essentially consists of a radio receiver 8 associated with a receiving antenna 9 and able to receive the alert signal emitted by any of the portable devices 1 being within range.
  • This radio receiver is followed by a demodulator 10 and an interface 11 associated with a relay 12.
  • the relay 12 is actuated and allows, by known means, to retransmit alarm to nearby surveillance personnel for rapid intervention on site. If necessary, the alarm can also be sent directly to the police or gendarmerie.
  • the individual portable transmitting device 1 is constituted by a small rectangular box 13 made of molded and sealed plastic material, the dimensions of which will be close to those of a lighter, by example 70 mm high, 35 mm wide and 10 mm thick, so that it can be held discreetly in the hand.
  • the switch 6 it is constituted here by a push button 15 projecting from the surface of the housing in a cutout 16 provided for this purpose.
  • This push button is made of plastic and has at its lower part a conductive metal part 17 capable of making electrical contact between two metal tabs 18 forming part of the printed circuit 14 and which are supported by flexible insulating parts 19.
  • a spring 20 is also interposed between the push button 15 and the printed circuit 14.
  • the portable transmitter device 1 is intended for single use.
  • the push button 15 is provided on its periphery with a serration 21 cooperating with a serration of corresponding shape formed in the wall of the housing 13, these serrations being oriented in such a way that when the button is pressed against of the action of the spring 20, it can no longer rise.
  • the housing of the push button 15 is normally covered by a protective cap 22, made integral with the housing 13 by means of a tongue 23 engaging in a groove 24 of the housing and of a part in the form of hook 25 engaging by snap-fastening on a retaining lug 26 provided with a breaking primer 27.
  • a projecting gripping tab 28 is also provided on the cap 22 at the level of the hook-shaped part 25.
  • the user carrying such a device must first of all, by pressing the thumb on the protruding tab 28 provided for this purpose, lift the protective cap 22, while maintaining the housing 13 between the palm and the other fingers of the hand, like a lighter. To do this, the user must overcome the resistance exerted by the retaining lug 26 which ends up breaking at the level of its breaking point 27. The cap 22 is thus unlocked, but cannot be replaced on the housing due to the rupture of lug 26.
  • the conductive metal part 17 of the button comes to bear on the two metal tabs 18, closing the supply circuit of the transmitter carried by the printed circuit 14.
  • the force exerted by the button on the tabs compresses the flexible insulating parts 19 and when the user releases his pressure on the button, the latter cannot go up because of the non-return system, while said flexible parts maintain electrical contact by absorbing the mechanical play inherent in such a system.
  • the transmitter 4 of the portable device 1 therefore continuously transmits a predetermined alert signal, preferably for a period limited to, for example, a few minutes, so as not to saturate the receiver 8 of the fixed installation 2.
  • This duration of limited operation can be easily obtained by more or less rapid exhaustion of the energy source 5, but it goes without saying that the same result could also be obtained by other means, for example a timer or a clock .
  • the portable transmitter device 1 also has a validity period limited in time. For this purpose, it transmits in its frequency band a signal coded by the modulator 3 which can be identified by the receiver 8 of the fixed installation 2. The list of identifiable codes is loaded in the fixed installation and it is thus possible deactivate series of codes corresponding to material deemed obsolete.
  • the portable device will no longer be recognized by fixed installations and will therefore become unusable. This makes it possible to regularly renew the fleet of portable devices and thus finance the equipment and operating costs of fixed installations. Such an arrangement also makes it possible to protect to a certain extent against the manufacture of pirate devices.
  • Another provision to combat pirate use by re-using the device consists in making the housing 1 in a non-removable manner without destroying the printed circuit 14.
  • each portable device 1 also has an individual code transmitted at the same time as the alert signal, thanks to a code memory 29 associated with the modulator 3, as shown in FIG. 1.
  • the fixed receiver device 2 is then equipped with a decoder 30 and a display 31, as shown in FIG. 2. It is thus possible to keep track of the code generated in a memory at the central station, which allows, if necessary , subsequently identify the author of the alarm using a file.
  • the remote alarm system is supplemented by a number of mobile receiving devices 32 such as that shown in FIG. 6.
  • This device comprises a directing antenna 33 followed by a receiver 34, d 'a demodulator 35 and an amplifier 36 associated with a loudspeaker 37. If necessary, this device may also include a decoder 38 and a display 39 in the case where use is made of an individual code for each device portable transmitter.
  • such a mobile receiving device 32 allows intervention personnel to locate, for example in a crowd, the area where the transmitter is on alert, orienting themselves according to the power sound output from the speaker.
  • the sound system could be replaced or supplemented by a light system or the like.
  • the remote alarm system according to the invention makes it possible to respond effectively to the problem of insecurity in public places.
  • the user carrying a miniature individual portable transmitter device 1 according to the invention can, when he is a victim or witness of an assault or an accident, alert discreetly and instantly by means of this device the police or security personnel. It will then be easily located thanks to the message transmitted by the fixed receiving device 2 being in range, then possibly more precisely thanks to a mobile receiving device 32. This makes it possible to reduce the number of monitoring teams and to take in advance measures to prevent the attacker (s) from fleeing, such as locking the access doors to the place being monitored.
