Simulation of Intelligent Fire Detection and Alarm System for a W d p .
AbstractFire is one of the major hazards in warships. A warship being avery complex structure, with sophisticated weapons, machinery, fueland ammunition is always at risk of fire. Restrictions on movement of ship's personnel and equipment requires automation in fire detectionand control systems. This paper describes the limitations of conventional fire detection systems, followed by the features of modern fire detection and alarnr (the so-called intelligent) systems and thetypes of fire detectors used in fire detection systems. The experimentalset-up used for simulating a simple system having 24 sensors connecteato the micro computer via digital input card is explained in detail withthe limitations of the experimental set-up and improvements that canbe made by incorporating serial communication in a loop, using fibre optics data links. and intelligent loop/interface units.
