Fault-Secure Multidetector Fire Protection System for Trains

This paper presents the design of a low-cost, robust, and fault-secure fire protection system for trains. This system consists of three temperature detectors and three smoke detectors, whose outputs are connected to a controller. The system produces three warning signals: fire, alarm, and cigarette. The system takes into account the presence or absence of wind and is expected to be extremely useful in cargo trains in developing countries. Also, the probability of false alarms is minimized. Finally, fault-tolerance is introduced into the system, and the increase in reliability is calculated
