YOUR GUIDE TO SHIP AUTOMATION AND NAVIGATION

The Mega-Guard Alarm Monitoring andControl System (AMCS) is the perfect automationsolution for medium to large size vessels.It can be used as a stand-alone AlarmMonitoring and Control System or theMega-Guard can be extended with powermanagement, cargo control, propulsioncontrol, integrated navigation and dynamicpositioning functions.

The Mega-Guard Alarm Monitoring and ControlSystem is the most reliable and field provensystem on the market because of the followingfacts:

Features

An Operator Workstation consists of a TFT Colour Graphic Screen, Operator Keyboard with Trackball, Marine PersonalComputer and optional Printer. The Operator Workstation provides a reliable and user-friendly operator interface to ensuresafe operation. The Operator Workstations are connected to each other via the redundant Ethernet link based uponUTP cabling. Two Operator Workstations, called the main server and the back-up server, are communicating via theredundant Ethernet link with the Control Processor with I/O Modules (Distributed Processing Units) and to the ExtensionAlarm System. This ensures a full redundant lay-out. Client Operator Workstations communicate with either the main server orback-up server Operator Workstation via the redundant Ethernet link. The on duty selection and engineer calling functions arefully redundant as upon failure of an Operator Workstation, the extension alarm system functions are automatically transferredto a back-up Operator Workstation. Various language options are available including Chinese, Japanese and others.

Operator Workstations

Operator Workstations built-up with MarinePersonal Computers under Windows 7embedded operating system and redundantEthernet link. Solid state disk is appliedinstead of hard disk. Main and back-upWorkstation to further ensure safety andreliability.D istributed Processing Units built-up withControl Processors equipped withI/O Modules and redundant Ethernet link.Each I/O Module has its own isolatedsensor supply and earth fault detector.Extension Alarm System is built-up withEAS Operator Panels equipped with agraphic LCD display and 12 illuminatedpushbuttons with redundant Ethernet link.

Whole system inter-connected by redundant Ethernet link. Cabling with star or ring topology or a combination ofstar and ring topology. W hole system operating directly on 19~32VDC power supply and all components have low power consumption.U ninterruptable Power Supply providing fail safe 24VDC output. P rogramming in accordance with international PLC programming standard IEC61131-3 (ST).T ype approved by all major classification societies.

Control Processors with I/O Modules (also called DPU) are mounted on a DIN rail; close to sensors andactuators to minimize cabling. The Control Processor is connected to the redundant Ethernet link forcommunication with the main and back-up server Operator Workstations and for communication withother Control Processors. Each I/O channel on an I/O Module has a LED indication and a channelidentification text window. This can be used for back-up and local read-out of alarms and status.Each I/O Module is equipped with an isolated sensor supply in order to feed sensors. In addition,the I/O Module contains an earth fault detector. A Control Processor with I/O Modules fully executescontrol, alarm and monitoring functions even when no Operator Workstation is connected. Programmingof control functions is done via the programming language PAL1131 which is in accordance withinternational PLC standard IEC61131-3 (ST). Sensors and actuators are directly wired to the detachableterminal strips on the I/O Modules. Serial interface links are connected to Serial link I/O Modules.

The Extension Alarm System is a highly reliable engineer callingsystem, which extends the Mega-Guard AMCS for unmannedmachinery space operation. On duty selection and engineercalling functions are executed on a dedicated mimic on theOperator Workstation.

A Control Processor supports up to 8 I/O Modules and up to 4 Serial link I/O Modules to external devices.Serial interface links will be connected via the Modbus RTU or NMEA protocol (other protocols optional).The Control Processors with I/O Modules and Serial link I/O Modules are installed in DPU cabinets orinside a console on a DPU DIN rail.

The dedicated mimic display on the Operator Workstationcontains the following fields:

On duty selectionA ttended / unattended (manned / unmanned) engine roomE ngineer callingP atrol timer / engineer safety system (dead man timer)

EAS Operator Panels are installed in bridge and accommodationareas. The EAS Operator Panels are equipped with the following:

Graphic LCD displaydisplaying individual alarms. On duty lamp. 8 x group alarm lamp & buzzer.

Fire alarm lamp with buzzer. Call ECR / bridge pushbuttons / lamps. Accept / stop horn pushbutton. Dimming pushbuttons (Arrow left / right).
