SOLID-STATE CONTROLLED FIRE HAZARD DETECTION AND QUENCHING SYSTEM

Abstract

This paper presents a novel scheme to detect the
fire hazard in air and ground vehicle and to quench
the fire in a reliable way. Microcontrol/er based
fire hazard detection and quenching .system is
developed, tested and found working satisfactory.
Its response is very fast to quench the fire hazard
before it spreads out. It is smart to ffiJoid any false
alarming in case of momentary fire occurrence.
,Special emphasis has been laid down in choosing
the precision amplifier for the thermocouple,
digitizer, and solid-state relays, which makes the
system reliable. It has built-in-test facili(y and any
malfunction of system is indicated. It has under
gone the environmental test successfully.
