Abstract

AbstractAiming at the shortcomings of the fire alarm system, a kind of intelligent fire alarm system based on GSM network is proposed. The system uses AT89S52 microcontroller as the core of the control system to implement the collection of temperature and smoke information and the fire automatic alarm processing. Communication with the users is fulfilled through the GSM global mobile communication in this system. Its short message transmission mode has broken the geographical constraints. It can achieve that the fire information is sent to the mobile phone of the relevant personnel accurately and timely when a fire occurs. It brings the convenience of taking the fire-protection measures in time. Experimental result is the effect. It can meet the design challenge.KeywordsGSMtemperature sensorsmoke sensoralarm system
