摘要
为预警建筑物尤其是文物古建电气火灾的发生,设计了一种基于LoRa无线传输技术的电气火灾监控系统。该系统中探测器通过监测线路温度及剩余电流的数值大小,采用LoRa无线传输技术将报警信息上传给监控主机通知值班人员,从而预防电气火灾的发生。在古建内的现场测试表明,该系统传输距离远、穿墙效果好。此研究为实现电气火灾的无线监控报警在文物建筑中的应用提供了理论与技术支撑。
An electrical fire monitoring system based on Long Range(LoRa)wireless transmission technology is designed for early warning buildings,especially in ancient buildings.In this system,by monitoring the temperature of the line and the value of the residual current,the alarm information is uploaded to the monitoring host by LoRa wireless transmission technology to notify the monitor on duty,so as to prevent the occurrence of electrical fire.After field testing in ancient buildings,the results show that the system has a long transmission distance and a good wall penetration effect.This study provides a theoretical and technical support for the application of wireless monitoring and alarm in electrical building fire protection.
