Abstract
Description
Elektroakustischer Warnsignalgeber (EWG-S) zur manuellen Bedienung durch Sicherungsposten für die Warnung von Arbeitskräften bei Arbeiten im Bereich von Bahnanlagenelectroacoustic Warning buzzer (EEC-S) for manual operation by means of security items for the Warning of workers for work in the area of railway facilities
Der EWG-S ist ein tragbares Warngerät, welches durch Sicherungsposten benutzt werden kann. Es dienst zur Abgabe sogenannter Rottenwarnsignale (vgl. ESO Eisenbahn-Signal-Ordnung, Abschn. „Rottenwarnsignale") in hoher Lautstärke (ca. 120 dB). Diese Signale zeigen den zu sichernden Arbeitskräften an, wie sie sich in bestimmten Situationen bei der Annäherung von Schienenfahrzeugen zu verhalten haben. Derzeit werden für die manuelle Warnung Geräte (Tyfone) genutzt, die mittels CO2-Druckgas betrieben werden. Der Mangel bei diesen Geräten liegt darin begründet, dass sie nicht ausfallsicher gestaltet sind und eine zusätzliche CO2-Emmission erfolgt.The EEC-S is a portable warning device that can be used by security guards. It serves to deliver so-called riot warning signals (see ESO Railway Signal Order, section "Rottenwarnsignale") in high volume (about 120 dB) .These signals indicate the workers to be secured, as they approach in certain situations Currently, the manual warning uses devices (Tyfone) powered by CO 2 compressed gas, the shortcoming of which is that they are not fail-safe and have an additional CO 2 emission ,
In „Automatische Rottenwarnanlage Autoprowa" (EI-Eisenbahningenieur (48) 3/97, Seite 12–15) ist eine Rottenwarnanlage der Firma Zöllner GmbH Kiel beschrieben, welche als optisch akustisches Warnsystem zur kollektiven Warnung von Personen im Gleisbereich dient. Aus Gründen der Eigenüberwachung und Redundanz sowie zur Überwachung der Kabel besteht eine solche Anlage aus mindestens zwei Hörnern WGH, einer Signalsteuereinheit und entsprechende Einschalt- bzw. Ausschaltkontakten.In "Automatic Rottenwarnanlage Autoprowa "(EI railway engineer (48) 3/97, page 12-15) is described a Rottenwarnanlage the company Zöllner GmbH Kiel, which as a visual acoustic warning system for collective warning used by people in the track area. For reasons of self-monitoring and redundancy and monitoring the cable consists of such a system of at least two horns WGH, a signal control unit and corresponding switch-on or switch-off.

Bisher entwickelte elektronische Warngeber sind sämtlich für den Einsatz in sogenannten automatischen Warnsystemen konzipiert worden und verfügen bei einem Einsatz als Einzelgerät nicht über die erforderlichen Ausfallsicherungen, da die erforderliche Redundanz bestimmter Baugruppen (Lautsprecher, Energieversorgung) nur durch den Einsatz mehrerer gekoppelter Geräte erzeugt wird.So far developed electronic warning devices are all for use in so-called automatic warning systems have been designed and feature a use as a single device no over the necessary failover, given the required redundancy certain components (speakers, power supply) only by the use of multiple coupled devices is generated.
Das erfindungsgemäße EWG-S erzeugt den nach ESO geforderten Mischton aus zwei unterschiedlich hohen Tönen mittels des Einsatzes zweier, redundant aufgebauter, Lautsprecher. Sollte ein Lautsprecher ausfallen, wird dies neben dem fehlerhaften Klang (Ton in nur einer Frequenzlage) durch eine optische Anzeige am Gehäuse angezeigt.The EEC-S according to the invention produces the mixed sound required by ESO of two different high notes by the use of two, redundantly constructed, speakers. Should a speaker fail, this will be next to the faulty one Sound (sound in only one frequency position) through a visual display on the housing displayed.
Die beiden Lautsprecher werden während ihres Betriebes mittels Strommessrelais überwacht.The both speakers will be during their operation monitored by current measuring relay.
Die Ansteuerung der Lautsprecher erfolgt von einem Bedientableau aus, welches über ein Kabel und Kupplung mit dem Gerät verbunden ist. Diese wird auf Kabelbruch überwacht. Sollte eine Unterbrechung des Kabels erfolgen, werden die Lautsprecher automatisch aktiviert und geben einen dauerhaften Warnton ab. Im Bedientableau befinden sich zwei redundant aufgebaute Taster. Im Falle des Defektes eines Tasters steht somit ein zweiter Taster zur Verfügung.The The loudspeakers are controlled from a control panel, which over a cable and coupling is connected to the device. This one will monitored for cable break. If there is a break in the cable, the speakers will sound automatically activates and emits a permanent warning tone. In the control panel There are two redundant buttons. In case of defect a push button is thus a second button available.
Das Gerät wird über 24 V DC Akkus betrieben. Das Gerät verfügt über zwei Akkusysteme, ein Haupt- sowie ein Notsystem. Der Betrieb des jeweiligen Systems wird über optische Anzeigen am Gerätegehäuse angezeigt. Der Ladezustand des Hauptsystems wird über eine Kapazitätsanzeige mit farbigen LED's angezeigt. Unterschreitet die Ladekapazität einen bestimmten Wert, wird zunächst ein Warnton über einen im Handbedientableau angebrachten Summer erzeugt, welcher dem Sicherungsposten signalisiert, dass das Gerät umgehend zu laden ist. Bei weiterem Unterschreiten der Ladekapazität wird automatisch ein zeitgesteuerter Warnton über die beiden Lautsprecher am Gerät erzeugt. Nach Ablauf der Zeit können die Sirenen nicht mehr zugeschaltet werden. Die Funktion der Anlage ist erst nach Aufladen der Akkusysteme wieder möglich.The Device is over 24V DC batteries operated. The device has two Battery systems, a main and an emergency system. The operation of each Systems will be over optical displays are displayed on the device housing. The state of charge of the main system is indicated by a capacity indicator with colored LEDs displayed. If the loading capacity falls below a certain value, first a warning tone over generates a buzzer mounted in the hand control panel which indicates to the backup item that the device is to be loaded immediately. At further Below the loading capacity will automatically be a timed warning tone over the two speakers on the device generated. After the time has expired the sirens are no longer switched on. The function of the system is only possible after charging the battery systems.
Die Vorteile des Warnsignalgebers nach der Erfindung liegen bei der Ausfallsicherheit der einzelnen Baugruppen.The Advantages of the warning signal generator according to the invention are in the Resilience of the individual modules.
