Abstract:

The traditional fire alarm system is only used to detect a particular physical or chemical signal of the fire,and therefore false alarm and failure alarm can occur easily.To solve this problem,we apply the multi-sensor composite detection technology and wireless communication technology in the fire detection and alarm system,and design an intelligence distributed wireless fire detection alarm system,which is based mainly on the STM32 control chip.The system can collect the concentration of CO,smoke density and temperature of three fire parameters simultaneously.Using wireless communication technology for data transmission and adopting the intelligent algorithm to process and judge the information of fire,the system can give fire warnings timely and accurately after debugging.
