Development of Raspberry Pi applied to Real-Time Monitoring of Overall Equipment Effectiveness (OEE)

Abstract

Overall Equipment Effectiveness (OEE) is a production machine performance measurement system. Performance measurement with OEE consists of three main parameters in the production machine, namely Availability (machine availability time), Performance (number of units produced) and Quality (quality produced). Many OEE monitoring modules are on the market. These modules are still very expensive so most companies are still unable to implement OEE into production machines. In this research, a software called OEEMAX which functions for OEE monitoring has been developed to be installed on Raspberry Pi. OEEMAX was built to be able to run on Raspberry and be able to read inputs from sensors. OEEMAX is also able to communicate with all types of Programmable Logic Control (PLC). The advantage of Raspberry Pi is the price of the module which is very cheap and uses open source operating system. OEEMAX has been successfully developed and applied to Raspberry Pi. It is able to read sensors through general purpose input / output (GPIO) and communicate with PLC using RS-232 protocol. In addition, it is also capable to send OEE data to SQL server.
