6.1.2 Data Acquisition, Processing, and Validation
The processing of relevant data is done using the Bosch Energy Platform, where
the measured values are recorded and checked, so that processed data is then
stored in the database as error-free as possible. The data check includes the control of complete data transmission, the value calculation of missing data records
as well as checks on measuring ranges and data consistency. In addition, the
necessary conversions and aggregation of the raw data is done. The data of the
energy platform is made available to the individual company divisions. To protect workers against productivity measurements, the energy data is measured with
a 1-minute-resolution but then aggregated to a 15-minute interval. With process
times of half a minute, such grossly aggregated data cannot be used for energy
efficiency optimizations. Therefore, different data resolutions 4 are subsequently
tested to determine an appropriate aggregation level.
The energy data acquisition of the high-resolution data was done by hardware
controllers installed at the machines specially for this purpose. Over a period of
4 The data measured at a resolution of less than 15 minutes has been collected for a short
period of up to three weeks and is used for scientific purposes only without any linkage to
employee data.
