Description
Anordnung zur Übermittlung von Signalen zum Führer eines Fahrzeuges Es wird neuerdings die Forderung erholen, auf Fahrzeugen, insbesondere Lastkraftwagen, Signale, die von anderen Fahrzeugen abgegeben werden; mit Hilfe von geeigneten Einrichtungen zu verstärken und dem Führer des Fahrzeugs zu übermitteln. Es ist für den Fachmann naheliegend, zu diesem Zweck einen Röhrenverstärker bekannter Art zu verwenden, der durch ein Mikrophon gesteuert wird, das .am Ende des Fährzeugs aufgehängt ist. Ein entsprechender Lautsprecher befindet sich dann in der Nähe des Führers.Arrangement for the transmission of signals to the driver of a vehicle It will recently recover the demand on vehicles, especially trucks, Signals emitted by other vehicles; with the help of suitable facilities to reinforce and convey to the driver of the vehicle. It's for the professional obvious to use a tube amplifier of a known type for this purpose, controlled by a microphone that is suspended from the end of the vehicle. A corresponding loudspeaker is then located near the guide.
Da ein Röhrenverstärker gegen mechanische Erschütterungen sehr empfindlich ist und einen erheblichen Aufwand an Stromquellen benötigt, hat man bereits an seiner Stelle Mikrophonverstärker verwende. Mikrophonverstärker bestehen bekanntlich ausR einer Anzahl von hintereinandergeschalteten Mikrophonen, die sich über :elektromaginetische Systeme kaskadenartig steuern. Sie genügen für die vorliegende Aufgabe vollstä#ndi;g, da es nicht darauf ankommt; frequenz- und phasengetreu zu übertragen, wie dies bei den üblichen Verwendungszwecken eines Röhrenverstärkers gefordert wird.As a tube amplifier is very sensitive to mechanical vibrations is and requires a considerable amount of power sources, you already have at your Use microphone amplifier instead. As is known, microphone amplifiers consist of R. a number of microphones connected in series, which are via: electromaginetic Control systems like a cascade. They are completely sufficient for the task at hand, since it doesn't matter; to transmit true to frequency and phase, as is the case with the usual uses of a tube amplifier is required.
Es ist weiterhin bekannt, zur Übermittlung von Signalen zum Führer von Kraftfahrzeugen ,abgestimmte Empfänger zu verwenden. Die Selektion erfolgt dabei durch geeignete akustische oder elektrische Filter. Derartige bei einer Tonfrequenz selektiv arbeitende Filtererfordern jedoch einen verhältnismäßig großen Aufwand. Es ist auch bekannt, das Aufnahmemikrophon selbst auf die Signalfrequenz abzustimmen. Derartige Mikrophone- haben jedoch den Nachteil, daß sie außerordentlich erschütterungsempfindlich sind, so daß sich die Geräusche längs des Weges besonders stark auf das Mikrophon übertragen.It is also known to transmit signals to the guide of motor vehicles to use coordinated receivers. The selection is made through suitable acoustic or electrical filters. Such at a tone frequency selectively operating filters, however, require a relatively large effort. It is also known to tune the recording microphone itself to the signal frequency. However, such microphones have the disadvantage that they are extremely sensitive to vibrations are so that the noise along the way is particularly strong on the microphone transfer.
Um trotzdem die Hüpensignale gut von den anderen Straßengeräuschen unterscheiden zu können, wird :erfindungsgemäß vorgeschlagen, zur Erzielung der Selektionswirkung Rden. Mikrophonverstärker selbst durch geeignete Bindematerialien für -das Kohlepülver auf die Signalfrequenz abzustimmen.In order to keep the hopping signals away from the other street noises to be able to differentiate is: proposed according to the invention to achieve the Selection effect Rden. Microphone amplifier itself through suitable binding materials for -to tune the coal powder to the signal frequency.
Der Mikrophonverstärker V wird, wie aus der Abbildung ersichtlich, an geeigne' er Stelle, vorzugsweise federnd,an Gummibändern o. dgl., aufgehängt. Das Aufnahmemikrophon NI befindet sich am Ende des Fahrzeugs, der Lautsprecher L am Führersitz. Es ist selbstverständlich möglich" ;den Erfindungsgedanken bei Fahrzeugen aller Art, so z. B. auch auf Schiffen, -in gleicher Weise ;anzuwenden.The microphone amplifier V is, as can be seen from the figure, Suspended at a suitable place, preferably resilient, on rubber bands or the like. The recording microphone NI is at the end of the vehicle, the loudspeaker L. at the driver's seat. It is of course possible "; the idea of the invention in vehicles of all kinds, e.g. B. also on ships, -in the same way; to be used.
