Solid-state controlled fire hazard detection and quenching system

A Gebre-Egziabher

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 avoid 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 facility and any malfunction of system is indicated. It has under gone the environmental test successfully.
