Automatic Fire Alarm Method of Prefabricated High-rise Building Based on LoRa Technology
Automatic alarm is an essential part of the intelligent building system.Due to the poor application effect of the current method in the automatic electrical fire alarm of prefabricated high-rise buildings,not only the false alarm rate is high,but also the automatic response time is long.In view of the shortcomings and defects of the current method,this paper proposes an automatic electrical fire alarm method based on LoRa technology.Deploy smoke sensors and temperature sensors in high-rise buildings to collect building electrical fire signals,and use LoRa technology to spread spectrum modulation signal communication to realize communication transmission of electrical signals.Through comprehensive analysis of electrical fire signals,electrical fire risks can be monitored and identified,and alarm responses can be made to monitoring results.The automatic fire alarm of prefabricated high-rise building based on LoRa technology is realized.The experimental results show that the false alarm rate is less than 1％and the automatic alarm response time is less than Is.The design method has a good application prospect in the field of intelligent building monitoring.
