The emergency fire alarm system in smart buildings has the problem of high false alarm rate and long alarm interval.For this purpose,an indoor fire alarm system based on wireless transmission of sensor data is designed.On the hardware side,the fire detectors and alarms have been selected and designed,utilizing multiple sensors to monitor indoor temperature,humidity,and smoke.On the software side,the sensor data is transmitted wirelessly,and the data fusion technology is used to identify fire risks and quickly alert.The experimental results show that the false alarm rate of the system is less than 1%,and the alarm interval is about 114 ms,which can achieve accurate and real-time fire alarm.
