基于手机和GNSS的室内火灾预警系统设计

摘要

针对现阶段我国还有大量老旧建筑物没有安装火灾预警系统和部分新建筑物火灾预警系统无法正常使用的情况,设计并开发了基于手机和GNSS的室内火灾预警系统.该系统以手机为平台,具有普遍适用性,可以显示火灾发生的具体位置,使人员有计划的撤离,避免盲目逃生导致的不必要伤亡.经过测试,系统基本达到了设计意图,预警成功率在54.06%~74.58%.%Based on the fact that there are no fire warning system in a lot of old buildings and the fire warning system in some new buildings cannot work, a new indoor fire warning system based on mobile phone and GNSS is developed.The system is based on mo-bile phone, so it can be used in a wide range. In addition, the sys-tem can show the detailed position of the fire. Using the informa-tion of fire position,people can plan escape routes and avoid unnec-essary casualties. Testing show that the system achieves the ex-pected goal basically and the success rate of warning is between 54.06% and 74.58%.
