Fire protection system for cargo trains using fuzzy logic

This paper presents the design of a fire protection system for cargo trains in developing countries. The system is low cost and robust. It consists of three heat detectors and three smoke detectors whose outputs are connected to a microcontroller. The system produces three warning signals: Fire, Alarm and Cigarette. The system takes into account the presence or absence of wind. Also, the probability of false alerts is minimized because of the use of fuzzy logic in the design.
