Implementasi Counter Production Monitoring pada Mesin Tekstil berbasis Mikrokontroler

A Counter Production Monitoring (CPM) system was implemented to calculate automatically a machine speed, a production speed and a total production. This system was employed on a spinning machine in a textile industry to know machine efficiency and a number of thread productions. The system consists of some microcontroller-based hardware and software modules to detect machine rotation. Inductive proximity sensor and encoder gear were installed with a rotary machine shaft in 1 mm distance. A number of machine rotation was calculated from the number of pulses that detected by sensor for a certain time duration. Microcontroller calculated three production values and displayed on LCD by controlling three different push buttons. Subsequently, the data transferred to PC via serial communication to be displayed on PC. From three days testing, the system showed a different result of 0.35-0.4 HANK total production between CPM system and manual procedure using Tachometer. The different was due to the machine was assumed still working during dopping (change thread cone) process in the manual procedure. As a conclusion, CPM system can be used to know the machine efficiency and the number of thread production automatically.
