Abstract
A complete system with the associated hardware, software and graphical user interface for Overall Equipment Efficiency measurement was developed in this work and then thoroughly tested on a factory environment for a period of over three years. The system was designed to be easily utilized on a typical production line, where the products can be identified with a simple sensor, which could also be deployed without interfering the line itself and the related electronics. This work shows that an extremely cost-effective solution based on popular Raspberry Pi architecture can be effectively utilized for all the required tasks needed for a functioning independent system. Data collection electronics with the related database for storing the data and a web server for the graphical user interface and reporting, were all integrated on a single enclosure. In addition, an analysis software was developed to get the benefit from the collected data, and the software was further developed along with the graphical user interface based on the feedback from the collaborating factory. During the test period, over three million products were correctly detected, and all the stoppages were recorded. The developed system revealed important bottle necks on the production line.
