Fire detection systems have become an integral part of safer homes and work places. But, fire detection systems are not effectively deployed in industries and fireworks factories, particularly in south Tamil Nadu. This unawareness and lack of technology have led to several deaths in the past and in the present. In general, the fire detection systems that are conventionally used, have some shortcomings such as weakness to noise, inability to pin-point the fire consumed area and faulty alarming due to the use of analogue transmission with 4-20mA current lines. This project, “Fire control and signaling in Fireworks industries using Controller area network”, presents a network-based approach to deal with this critical application, with the help of Controller Area Network (CAN) for pin-pointing the area under fire, determining the extent of spread, extinguishing it by triggering the actuators and finally to signal the fire station, with the help of GSM (Global System for Mobile Communications) technology.
