Application of a wireless sensor networks and Web2Py architecture for factory line production monitoring

Abstract

In this paper a wireless sensors network (WSN) has been designed according to the IEEE 1451 standard and installed in a manufacturing cell. On-line monitoring data have been collected and stored in a database through a Web2Py framework. A case study on the usage of WSN to perform an industrial performance analysis is made. A set of measures, comprehensive of all the production parameters of 4 different line productions, have been used to analyze the performances of the company. Effectiveness and reliability indexes, such as the mean time to repair (MTTR) and mean time between failures (MTBF) of the machines, overall equipment effectiveness (OEE) and the total effective equipment productivity (TEEP) have been computed and compared to the world-class manufacturing (WCM) standards.
