Definitions

  • the present invention relates to the field of swimming pool or sea rescue, and beach surveillance.
  • the drowning prevention equipment for rescue at sea, the drowning prevention equipment consists essentially of a VHF radio transmitter box.
  • the transmitter When the person fitted with such a radio transmitter falls into the sea, the transmitter is switched on by means of contact closure by water conduction and emits a VHF signal which triggers the alarm or the means of rescue.
  • this system is unreliable because it only works when the person is not submerged.
  • the accidental drowning prevention system is characterized in that it comprises: at least one waterproof case intended to be worn by the bather, for example on his wrist, and comprising an immersion detector triggering an electronic counter connected to a comparator controlling an acoustic transmitter triggered from a predetermined threshold value, - at least one hydrophone, placed at the bottom of the water, to capture any acoustic waves, - an alarm control box and / or a rescue device connected to the hydrophone by a waterproof cable.
  • FIG. 1 represents a swimming pool equipped with the following rescue device: a bather, 1, carries on his wrist a waterproof case, 10, mainly comprising a small acoustic transmitter and an associated electronic circuit.
  • a hydrophone, 2 is placed or fixed to the bottom of the pool and connected to a control box for any alarm, 3, or to a suitable rescue means.
  • FIG. 2 represents the electronic circuit of the waterproof housing, 10, comprising an immersion detector, 11, triggering a counter 12 punctuated by a clock, 13, and which can be reset to zero by a control signal coming from the immersion detector , 11.
  • the output of this counter, 12, is connected to a comparator, 14, and compared to a threshold value corresponding to a predetermined period of time.
  • the comparator output controls an acoustic transmitter, 15.
  • Immersion detection can be obtained in several different ways.
  • the simplest version includes a contact closing by water: each time the current passes it triggers the counter.
  • Immersion detection can also be obtained from a pressure sensor made up of a pad of variable resistive material depending on the pressure, for example a silicon pad, fixed on the waterproof case.
  • the counter is triggered when the pressure varies.
  • immersion detection can also be obtained actively, on the one hand by equipping the alarm box with a VHF radio transmitter containing an antenna, and on the other hand by equipping the waterproof housing with a VHF receiver. Since VHF radio waves do not propagate underwater, immersion detection is obtained by the absence of clear VHF reception, that is to say when the VHF reception level is below a level predetermined.
  • the 3 types of immersion detection described above can coexist, the counter being activated when one of the conditions is met.
  • the operating principle is as follows: each time the waterproof case is submerged, electronic counting begins; the counter is reset to zero at each immersion interruption. When the count exceeds a limit value, an acoustic emission is triggered. This transmission is received by the hydrophone, which sends a signal to the alarm box or the planned rescue means.
  • the transmitter is omnidirectional and its transmission frequency is high enough to be located outside the frequency range of pool noise, for example 10 kHz.
  • FIG. 3 represents the electronic circuit of the alarm box, 3.
  • This alarm box, 3, is portable and waterproof and does not have any particular characteristics compared to a conventional house alarm. It includes a selective filter, 30, eliminating pool noise, connected to a receiver, 31, which controls a pulse generator, 32, triggering an alarm, 33, or a means of rescue. It provides selective reception by filtering the electrical signal supplied by the hydrophone. It can also include a regular self-test to ensure the proper functioning of the various elements of this alarm box.
  • Redundancy is advantageously provided by connecting 2 hydrophones to the alarm box.
  • a third hydrophone it is possible to locate the person in difficulty in the swimming pool.
  • a network of hydrophones ensures beach surveillance.
  • the means of rescue for a swimming pool can consist of a solenoid valve which controls the emptying of the water of the swimming pool or the inflation of a float bringing up a rigid frame net normally found at the bottom of the swimming pool.
