Abstract
A method for processing data sets having at least one time series. These are measurement values of sensors that are sensed at certain times. The data of the measured values and the respective times at which the data were sensed are stored as data elements of the time series. The method compresses the data set by rounding the sensed data with subsequent decimation of the data elements of the data set which are contained in the time series.
Claims17
A method for processing data sets containing at least one time series corresponding to a series of measurement values by a computing unit, wherein the time series contains data acquired at specific times and a respective time of the data acquisition as data elements, the method comprising:
- rounding the acquired data with a subsequent decimation of the data elements of the data set contained in the at least one time series;
- storing the decimated time series of the data set in the computing unit and/or transferring the decimated time series of the data set to an external computing device;
- and
- acquiring the measurement values as integer numbers or as floating-point numbers and converted into integer numbers,
- wherein, as part of the conversion of the floating-point numbers of the data elements of the time series into integer numbers, an offset “o” is subtracted and the result of the subtraction is divided by a factor.
A device for processing data sets containing at least one time series corresponding to a series of measurement values, wherein the time series contains data acquired at specific times and a respective time of the data acquisition as data elements, the device comprising:
- at least one computing unit configured to acquire a measurement value of at least one connected sensor or to receive measurement values acquired by the sensor at successive times;
- wherein the computing unit forms at least one time series with the measurement values and associated measurement times,
- wherein the computing unit rounds the acquired data with a subsequent decimation of the data elements of the data set contained in the at least one time series,
- wherein the decimated time series of the data set is stored in the computing unit and/or transferred to an external computing device,
- wherein the measurement values are acquired as integer numbers or as floating-point numbers and converted into integer numbers, and
- wherein, as part of the conversion of the floating-point numbers of the data elements of the time series into integer numbers, an offset “o” is subtracted and the result of the subtraction is divided by a factor.
