MONITORING AND FAULT DETECTION OF MAIN ENGINE COOLING WATER BASED ON MODBUS COMMUNICATION AND INTERFACE

Abstract

The main engine failure can damage the engine system, reduce navigation safety, and lead to severe maritime accidents. The cooling system is essential to avoid engine mechanical efficiency reduction and engine failure due to overheating. Thus, a monitoring and fault detection system is needed. The system made is based on RS485 Modbus Communication and Interface. The acquisition device uses existing components in the 7S-50MC Diesel Engine. PLC is used as a processing device and Logic Panel Autonics S070 as an interface. From the test, fault detection in this study can provide error indicators when abnormal conditions occur. In addition, data monitoring and system error indication can be displayed clearly on the Interface. Testing this system proves compliance with Biro Klasifikasi Indonesia (BKI) rules regarding the machinery alarm system. The developed research can be the basis for a more complex and reliable monitoring and fault detection system for application on ships.
