dc.description.abstract | Abstract: The primary purpose of an Addressable
Bilge Alarm Panel is to provide an early warning of
the bilge level of a vessel so that the personal,
equipment and valuable resources can be protected
and action is taken to remove bilges as soon as
possible, all according to a predetermined plan.
This study presents aspects of the bilge alarm
system onboard Sri Lanka Naval Ship (SLNS)
Sagara, by analyzing the existing system based on
automation and advanced microcontroller
programming using Raspberry Pi3, and ATMEGA
328P microcontrollers. The designed system is an
addressable type bilge alarm system that
communicates in serial RS 485. The novelty of the
designed system are the own data protocol used in
RS 485 communication, voice command of specific
bilge location and the self designed advanced
graphical user interfaces (GUI). In the simulation
process, the bilge alarms may be raised
automatically by a bilge sensor or manually by a
person operating a test button. This response
indicates the exact location of the ship on the given
blueprint of the touch panel and provides an
automatic warning alarm of the bilge location
through the ship fitted General Alarming system.
The study covers the designing process,
implementation, microcontroller and Touch Panel
programming, simulation process, testing and
commissioning process. The designed system was
installed onboard and tested for several months
under different sea conditions by experienced
Senior Electrical Engineers and Marine Engineers
of SLN, then the system was commissioned on 03rd
February 2022. | en_US |
