IT infrastructure and server architecture

Setting up the information technology (IT)- infrastructure with servers for InfluxDB (time series database), Grafana and web service. Standardized architecture as the basis for data acquisition and evaluation.

Worker terminal and measuring station integration

Provision of a worker terminal with measuring station and connection of the measuring device. Development of an active Excel-sheet for simple data acquisition and deviceäinteraction.

Data acquisition and interfaces

Recording of information from the Open Platform Communications (OPC)- server. Import of Excel-sheets with manual measurements to merge all data sources.

Business intelligence and analysis

Development of business intelligence (BI)- services in Python/Windows. Automated preparation, analysis and calculation of relevant key figures for the store floor.
