Definitions

  • the present invention relates to a device for protecting trunk rooms, by an acoustic contactor detector circuit coupled to an alarm device of any suitable type, for example smoke, light, sound and gas.
  • the device object of the present invention is particularly intended for the protection of vaults. It notably includes an acoustic accumulation switch which controls the alarm when the level of average cumulative noise exceeds a certain threshold and which can be associated with a smoke generator and a circuit breaker. When triggered, the device allows the vault to be plunged into total darkness by switching off the lighting and to release thick smoke inside or outside which undoubtedly attracts the attention of passers-by.
  • Another advantage of the device is that it can be used in the presence of customers.
  • the device is harmless to people and requires no intervention from staff.
  • the device object of the invention detects by means of a low frequency microphone all ambient noise present in the protected places.
  • the detected signal is selectively amplified.
  • a converter makes it possible to recover a voltage proportional to the level analyzed.
  • This voltage is accumulated in a capacitor with high capacity which allows to integrate all variations.
  • This level is displayed by a light ramp. This same level is analyzed by a threshold detector determining the alarm level.
  • an anti-masking device In order to get rid of any masking, an anti-masking device is provided.
  • An ultrasonic transmitter continuously transmits a signal to the ultrasonic microphone placed near the low frequency microphone. This signal is amplified according to the same principle as the low frequency part. The presence of a voltage ensures the proper functioning of the system.
  • a threshold detector analyzes the alarm threshold.
  • a self-protection loop is wired which triggers the alarm if there is intervention on the loop.
  • a logic circuit analyzes this information and determines, based on the data, whether to trigger an alarm. This triggering is controlled by a timer which limits the duration of the alarm.
  • a dynamic type omni-directional microphone 1 analyzes ambient noise and in particular frequencies below one thousand hertz with good fidelity.
  • a preamplifier 2 organized around an integrated circuit of the operational type amplifies the signal.
  • This signal is in a second step amplified by a second integrated circuit.
  • This second step has the particularity, by means of a selective amplifier 3, of amplifying only the low frequencies such as those originating for example from shocks on metal walls. The choice of the limits of the response spectrum of the selective circuit depends on the application and the acoustic behavior of the protected place.
  • the signal from the selective amplifier 3 is converted into direct voltage and integrated by a converter 4.
  • the converter 4 includes a capacitive time constant system of any known RC type making it possible to integrate the noises received and also to discharge the capacity according to the chosen time constant. In addition, this capacitive system makes it possible to delay any event and not to react to any extraneous noise. In this way it is possible to measure an accumulation of unusual noises and also to exclude from the measurement a specific noise such as a door slam for example.
  • a display system 5 with a light ramp gives the level of ambient noise at all times. This stage is organized around a specialized circuit and makes it possible to visualize the critical threshold.
  • a threshold detector 6 organized around an operational amplifier intervenes to precisely adjust the trigger threshold. This logic output signal is processed by a circuit 7.
  • An ultrasonic transmitter 8 attached to an ultrasonic capsule 9 emits a permanent signal.
  • a receiving capsule 1 0 sensitive to ultrasound is placed near the low-frequency microphone 1 and the received signal is amplified by the preamplifier 11 and the ultrasonic amplifier 12.
  • a converter 13 transforms the signal into voltage in order to use it with the threshold detector 14 which will determine the alert threshold.
  • the general system is therefore dynamically self-protected.
  • a self-protection chain 20 (passive system) controls the closing of all the boxes and warns of any attempts to open the various devices.
  • the timer controls two special stages intended for lighting the smoke 16 and switching off the lights 17.
  • the general device is supplied from 220 volts and is transformed into 12 volts DC using a stabilized supply 18. This supply also charges a battery 19 which serves as a backup in the event of a failure of the EDF network.
  • the device which is the subject of the invention is intended for the protection of safe rooms and more generally for all rooms containing precious objects and which must receive the public.
  • the system can also be triggered below a minimum noise level, which would correspond to an abnormal state of operation of the room.
  • system can be used to trigger any type of alarm or suitable alarm device.
