SEMINAR ON fire detection and monitoring by satellite

GPRS通信技术实现了多方式遥控设防撤防,解决了主控制器操作 的实时记录问题,为事后分清责任提供了技术保障。现场调试结果表明,系统操作简便灵活,有效地实现了对室内环境信 息(如温度、湿度)的实时监控、险情检测(如火警、被盗、可燃气体泄漏及水泄漏)、多方式遥控设防撤防、远程监控和报警 以及操作数据实时记录等功能,提高了家庭安防报警的可靠性。 -GPRS communication technology to achieve a multi-way remote maximum se

文提出了一种由可编程控制器(PLC)控 制的火灾自动探测报警控制器-Paper presents a programmable controller (PLC) to control the fire of automatic detection and alarm controller

Traditional fire detection algorithms mainly rely on hot spot detection using thermal infrared (TIR) channels with fixed or contextual thresholds. Three solar reflectance channels (0.65 μm, 0.86 μm, and 2.1 μm) were recently adopted into the MODIS
