Abstract

Verfahren zur Datenübertragung von einem Sensor (1) auf einen Empfänger (4) bei dem jedes ursprüngliche Datenwort stellenmäßig in mindestens zwei getrennte Kurzdatenworte (MSN, LSN) zerlegt wird. Die getrennten Kurzdatenworte (MSN, LSN) werden mittels einer Digital-Analogumsetzung (15) jeweils in ein analoges Pseudosignal umgesetzt und im Multiplexbetrieb über einen Ausgang des Sensors und eine Übertragungsstrecke (3) dem Empfänger (4) zugeführt. Im Empfänger werden die analogen Pseudosignale mittels eines Analog-Digitalumsetzers (15) wieder in Kurzdatenworte (MSN, LSM) zurückgewandelt und stellenrichtig zusammenfügt, so dass das resultierende Datenwort dem ursprünglichen Datenwort entspricht.

Figure imgaf001
Method for data transmission from a sensor (1) to a receiver (4) in which each original data word is decomposed in place into at least two separate short data words (MSN, LSN). The separated short data words (MSN, LSN) are respectively converted by means of a digital-to-analog conversion (15) into an analog pseudo signal and fed in multiplex mode via an output of the sensor and a transmission path (3) to the receiver (4). In the receiver, the analog pseudo signals are converted back into short data words (MSN, LSM) by means of an analog-to-digital converter (15) and combined in the correct position so that the resulting data word corresponds to the original data word.
