Zusammenfassung
Automotive paint systems include very environmental relevant processes and are complex systems, which complicate the data acquisition for material flow analyses. With the help of a new developed client/server system consisting of three clients, VOC including material data can be captured systematically and locally to build a better knowledge of these consumption data for future balances and calculations. With the help of the mobile client, VOC including material flow data can be captured systematically and locally. It represents a developed guideline of data acquisition to capture such material flows. The mobile client also has to support users during inspections by detecting and identifying the data sources through a map function and a QR-Code function. With the desktop client, users can manage the inspections and evaluate the collected consumption data. The evaluation tables, generated by the desktop client, contain the percentage of the environmental relevant solvents. These tables are useful as an import for a VOC balance sheet tool, which is important e.g. for the VOC directive. The third client, the server client, contains the database and manages the communication between the other clients. Through a verification of the developed solutions practicality, it was demonstrated, that there are a few discrepancies in a paint shop between the present data of the operating data logging and the collected data by the client/server system. These discrepancies were verified by the comparison with the compared data of another paint shop. That means that the data quality increases through the using of the developed client/server system. Also media breaks could be avoided and the spending time for the inspections could be reduced by a good usability and a strict structured workflow.
