Abstract

The invention describes a method and apparatus for the acoustic signalling of cases of drowning in swimming pools, to guarantee reliable trigger of the alarm while avoiding any false alarms. This is effected basically by a switching element (1) in a water-tight encapsulation, which is disposed beneath the surface of the water and which, in the event of an alarm, triggers a first alarm device (2) and delivers an acoustic signal via a signal horn (5). A transmitter (6) is also connected to the alarm device (2) and transmits the alarm signal to a receiver at a distance and to another alarm device (10). Instead of the switching element (1), a microphone (12) can advantageously be used for cases in which the swimming pool water is frozen.

Description

Die Erfindung betrifft ein Verfahren zur akustischen Meldung von Ertrinkenden in Schwimmbädern nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a method for acoustically reporting drowning people in swimming pools according to the preamble of claim 1.

Bei einem bekannten Verfahren dieser Art wird die Bewegung der Wasseroberfläche des Schwimmbeckens durch ein in einem Schwimmkörper untergebrachtes schwingungsempfindliches Schaltelement überwacht, das im Alarmfall eine außerhalb des Schwimmbeckens angeordnete akustische Alarmeinrichtung über eine Kabelverbindung auslöst (DE-OS 27 43 192). Der Nachteil dieses Verfahrens ist darin zu sehen, daß bereits durch einen stärkeren Wind oder durch zufällig in das Schwimm­becken hineinfallende Äste, Steine oder andere Gegenstände ein Fehlalarm ausgelöst wird, weil das auf der Wasserober­fläche schwimmende Schaltelement alle Oberflächenbewegungen erfaßt und dadurch bereits den Alarm auslöst.In a known method of this type, the movement of the water surface of the swimming pool is monitored by a vibration-sensitive switching element housed in a floating body, which triggers an acoustic alarm device arranged outside the swimming pool in the event of an alarm via a cable connection (DE-OS 27 43 192). The disadvantage of this method is that a false alarm is triggered by a stronger wind or by branches, stones or other objects falling accidentally into the swimming pool, because the switching element floating on the water surface detects all surface movements and thereby triggers the alarm.

Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Ver­fahren und eine Vorichtung zur Durchführung dieses Verfah­rens zu schaffen, bei dem eine sichere Alarmauslösung beim Hineinfallen eines Ertrinkenden in das Schwimmbecken gewähr­leistet ist und ein Fehlalarm ausgeschlossen wird.The invention is therefore based on the object of providing a method and a device for carrying out this method in which a reliable alarm triggering when a drowning person falls into the swimming pool is ensured and a false alarm is excluded.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst. Weitere vorteil­hafte Ausgestaltungen der Erfindung sind in den Unteran­sprüchen angegeben.This object is achieved by the features specified in the characterizing part of claim 1. Further advantageous embodiments of the invention are specified in the subclaims.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen

  • Fig. 1 eine als Blockschaltbild dargestellte Schal­tungsanordnung des erfindungsgemäßen Verfah­rens und
  • Fig. 2 eine schematische Darstellung einer Vorrichtung zur Durchführung des Verfahrens.
An embodiment of the invention is shown in the drawing and will be described in more detail below. Show it
  • Fig. 1 is a block diagram of the circuit arrangement of the inventive method and
  • Fig. 2 is a schematic representation of an apparatus for performing the method.

Wie aus der Fig. 1 ersichtlich ist, besteht die als Block­schaltbild dargestellte Schaltungsanordnung zur akustischen Meldung von Ertrinkenden in Schwimmbädern aus einem im Schwimmbecken unterhalb der Wasseroberfläche fest angeord­neten Schaltelement 1, welches mit einer Alarmeinrichtung 2 verbunden ist, die von einem Akkumulator 3 mit einer bevor­zugten Betriebsspannung von 9 Volt bei einem Ruhestrom von Null Ampére gespeist wird, wobei der Akkumulator 3 tagsüber durch Solarzellen 4 aufladbar ist. An die Alarmeinrichtung 2 ist über ein Relais (in der Zeichnung nicht dargestellt) ein Signalhorn 5 angeschlossen. Bei Alarmauslösung schaltet das Relais und das Signalhorn 5 löst einen akustischen Alarm aus. Die Alarmeinrichtung 2 mit dem Signalhorn 5 ist außerhalb des Schwimmbeckens, z. B. am Schwimmbeckenrand, angeordnet. Um einen Alarm auch an einem vom Schwimmbecken entfernt liegen­den Ort empfangen zu können, ist an der Alarmeinrichtung 2 über eine Kabelverbindung ein Sender 6 angeschlossen, von dem im Alarmfall das Alarmsignal auf einen entfernt liegenden Empfänger 7 übertragen wird, wobei das Alarmsignal vorher von einem Vorverstärker 8 verstärkt wird. Am Empfänger 7 ist über einen Impuls-Umsetzer 9 eine weitere Alarmeinrichtung 10 mit einem Signalhorn 11 angeschlossen.As can be seen from Fig. 1, the circuit arrangement shown as a block diagram for acoustic notification of drowning people in swimming pools consists of a switching element 1 which is fixedly arranged in the swimming pool below the water surface and which is connected to an alarm device 2 which is preferred by an accumulator 3 Operating voltage of 9 volts is fed at a quiescent current of zero amperes, the accumulator 3 being rechargeable by solar cells 4 during the day. A signal horn 5 is connected to the alarm device 2 via a relay (not shown in the drawing). When an alarm is triggered, the relay switches and signal horn 5 triggers an acoustic alarm. The alarm device 2 with the signal horn 5 is outside the swimming pool, for. B. at the edge of the pool. In order to be able to receive an alarm also at a location distant from the swimming pool, a transmitter 6 is connected to the alarm device 2 via a cable connection, from which the alarm signal is transmitted to a remote receiver 7 in the event of an alarm, the alarm signal beforehand from a preamplifier 8 is reinforced. A further alarm device 10 with a signal horn 11 is connected to the receiver 7 via a pulse converter 9.

Die vorstehend beschriebene Schaltungsanordnung ist bei im Schwimmbecken 19 eisfreiem Wasser einsetzbar. Um jedoch auch bei gefrorenem Eiswasser die Alarmeinrichtung funktionsfähig einsetzen zu können, wird anstelle des Schaltelements 1 er­findungsgemäß ein speziell gekapseltes Mikrophon 12 in das eisfreie Wasser gehängt, welches die beim Einbrechen eines Menschen in das Eis verursachten Geräusche unter oder auf dem Eis aufnimmt, diese in einer nachfolgenden elektro­nischen Vorrichtung signalmäßig verarbeitet und den Alarmein­richtungen 2 und 10 im Alarmfall zuführt. Für diesen Fall wird die beim Hineinfallen eines Körpers in das zugefrorene Schwimmbecken erzeugte sinusförmige Schwingung von einem dem Mikrophon 12 nachgeschalteten Impulsumsetzer 13 in einen Rechteckimpuls umgesetzt, der über ein in der Zeichnung nicht dargestelltes Relais die Alarmeinrichtung 2 auslöst. Gleich­zeitig wird über den Sender 6 das Alarmsignal an den ent­fernt liegenden Empfänger 7 auf die den Alarm auslösende Alarmeinrichtung 10 übertragen. Als Sender kann vorteilhaf­terweise eine Infrarotvorrichtung, ein Ultraschallsender oder eine Funkeinrichtung dienen. Der Empfänger 7 kann auch eine bereits bestehende Hausalarmeinrichtung oder an eine im Auto oder in einem Wohnwagen installierte selbständige Alarmein­richtung angeschlossen werden. Ebenfalls ist es vorteilhaft, wenn der Empfänger 7 ein in der Zeichnung nicht dargestell­tes Mikrophon ist, welches in einem Raum zur Raumüberwachung von unerwünschten Personen (Einbrechern) aufgestellt ist.The circuit arrangement described above can be used with ice-free water in the swimming pool 19. However, in order to be able to use the alarm device functionally even in frozen ice water, instead of the switching element 1, according to the invention, a specially encapsulated microphone 12 is hung in the ice-free water, which picks up the noise caused by a person breaking into the ice under or on the ice, this in of a subsequent electronic device processed in terms of signals and fed to the alarm devices 2 and 10 in the event of an alarm. In this case, the sinusoidal vibration generated when a body falls into the frozen swimming pool is from one Microphone 12 downstream pulse converter 13 converted into a rectangular pulse that triggers the alarm device 2 via a relay, not shown in the drawing. At the same time, the alarm signal is transmitted via the transmitter 6 to the remote receiver 7 to the alarm device 10 which triggers the alarm. An infrared device, an ultrasound transmitter or a radio device can advantageously serve as the transmitter. The receiver 7 can also be connected to an existing house alarm device or to an independent alarm device installed in the car or in a caravan. It is also advantageous if the receiver 7 is a microphone, not shown in the drawing, which is set up in a room for room monitoring of unwanted people (intruders).

Um eine Alarmanlage vorteilhaft für den Überwachungsvorgang ausnutzen zu können, ist vorgesehen, daß der Empfänger 7 bei­spielsweise an eine Autobatterie mit einer Betriebsspannung von 12 Volt anschließbar ist.In order to be able to advantageously use an alarm system for the monitoring process, it is provided that the receiver 7 can be connected, for example, to a car battery with an operating voltage of 12 volts.

Im Rahmen der Erfindung kann der Empfänger 7 auch ein Rauch­melder, Temperaturfühler oder Wassermelder angeschlossen werden.Within the scope of the invention, the receiver 7 can also be connected to a smoke detector, temperature sensor or water detector.

In eisfreien Zeiten wird das gekapselte Mikrophon 12 durch das Schaltelement 1 ausgetauscht. Wie aus Fig. 2 ersichtlich ist, wird das wasserdicht gekapselte Schaltelement 1 vor­zugsweise an der Rückseite einer senkrecht zur Wasserober­fläche am Ausgang eines trichterförmigen Gehäuses 14 über eine Achse 15 drehbar gelagerte Klappe 16 angeordnet. Das Schalt­element 1 kann ein Quecksilberschalter sein. Die beim Hinfal­len eines körpers in ein Schwimmbecken 19 verursachte Wellen­bewegung wird vom Trichter 14 verstärkt aufgefangen und ver­setzt die Klappe 16 in eine Drehbewegung, wodurch der Queck­silberschalter 1 über eine mit der Alarmeinrichtung 2 ver­bundene Kabelverbindung 17 die Alarmeinrichtung schaltet und das Signalhorn 5 einen akustischen Alarm auslöst. Der im Schwimmbecken unterhalb der Wasseroberfläche in einer ent­ sprechenden Tiefe eingetauchte Trichter 14 ist an einem ab­gewinkelten Gestänge 18 befestigt, welches mit seinem einen Winkelteil 18a am Schwimmbeckenrand 19a angeordnet ist. Ein Fehlalarm, der durch starken Wind oder in das Becken fallen­de Zweige ausgelöst wird, ist durch die Anordnung des Schalt­elements 1 unterhalb der Wasseroberfläche ausgeschlossen. Durch die Ausbildung des Trichters 14 von der Klappe 16 mit dem Schaltelement 1 wird im Alarmfall ein sicheres Auslösen des Schaltelements gewährleistet, weil die vom Körper ver­ursachte Unterwasserbewegung verstärkt und komprimiert auf­gefangen auf die Klappe 16 gelenkt wird.In ice-free times, the encapsulated microphone 12 is replaced by the switching element 1. As can be seen from FIG. 2, the watertightly encapsulated switching element 1 is preferably arranged on the back of a flap 16 rotatably mounted via an axis 15 at the outlet of a funnel-shaped housing 14 perpendicular to the water surface. The switching element 1 can be a mercury switch. The wave movement caused when a body falls into a swimming pool 19 is increasingly absorbed by the funnel 14 and causes the flap 16 to rotate, as a result of which the mercury switch 1 switches the alarm device via a cable connection 17 connected to the alarm device 2 and the signal horn 5 triggers an acoustic alarm . The ent in the pool below the water surface Speaking depth immersed funnel 14 is attached to an angled linkage 18 which is arranged with its one angular part 18a on the pool edge 19a. A false alarm, which is triggered by strong wind or branches falling into the pool, is excluded by the arrangement of the switching element 1 below the water surface. By designing the funnel 14 from the flap 16 with the switching element 1, a safe triggering of the switching element is ensured in the event of an alarm, because the underwater movement caused by the body is directed to the flap 16 in an intensified and compressed manner.
