Abstract
A method for digital data transmission from a sensor to a control unit is described, the sensor values of the sensor being divided for data transmission at different resolutions. The sensor values form a first range of values including successive sensor values. The first range of values for data transmission is divided as a function of a variable relevant for the control unit.
Claims14
A method for providing digital data transmission of sensor values from a sensor to a control unit, the sensor values generated from characteristics measured by the sensor, the method comprising:
- dividing the sensor values into at least two ranges of sensor values for data transmission, each range of values being transmitted at different resolutions, the at least two ranges of sensor values including a first range of values including successive sensor values;
- wherein the sensor values are divided as a function of a variable relevant for the control unit;
- wherein a transmitter module executes the division of the sensor values as a function of the variable relevant for the control unit, wherein the variable includes the threshold values for a triggering algorithm,
- wherein the transmitter module selects the second range of values, in which the threshold values may appear, for transmission at a higher resolution, while it transmits the first range of values at a lower resolution, and
- wherein the transmitted sensor values are received by the control unit via a receiver module and are supplied to a processor for processing by the triggering algorithm.

- wherein a transmitter module executes the division of the sensor values as a function of the variable relevant for the control unit, wherein the variable includes the threshold values for a triggering algorithm,
- wherein the transmitter module selects the second range of values, in which the threshold values may appear, for transmission at a higher resolution, while it transmits the first range of values at a lower resolution, and
