چکیده
A marine automation system for merchant ships consists of machinery control & monitoring system and cargo control & monitoring system. Extension Alarm System (EAS) has been installed for machinery control & monitoring system to provide machinery alarms to bridge, cabins, and public areas. However, EAS of the latest marine automation systems requires the integrated functionality for both machinery and cargo monitoring. In this paper, we introduce general features of EAS and design Integrated Extension Alarm System (IEAS) for ACONIS-2000 system, which is the integrated marine automation system developed by Hyundai Heavy Industries co., ltd. Extension alarm panels of IEAS are classified by the system type and display the information received from the alarm server of ACONIS2000. Therefore, IEAS can transfer machinery and/or cargo alarms to the on-duty engineer according to the system type of alarms. In addition, IEAS provides the flexibility of the alarm group and duty configuration. 1. MARINE AUTOMATION SYSTEM A marine automation system for merchant ships such as oil and gas tankers, bulk carriers, and containers consists of machinery control & monitoring system and cargo control & monitoring system. The main purpose of the system is to give ship's engineers and/or officers all the basic alarms and status information in order to maintain safe and efficient operation of the machinery and cargo equipment. Marine automation systems have capabilities of providing requirements such as alarm and monitoring, tank level indication, engine/ auxiliary/generator control, remote diagnostics, and system integration according to clients' preference. There are many commercial marine automation systems: DataChief C20, MOS 2200, SSAS-Pro, and Mega-Guard MCMS. Each system is based on the architecture of distributed control concepts and provides similar functionality. The general features of marine automation systems are shown as follows:
