背景技术Background technique
随着社会的发展，人们对火灾的重视程度越来越大，因为火灾一旦出现，就会伴随着物质的损失；目前发生的几起大火，都不同程度遭受了巨大经济损伤。为了避免火灾的发生，很多机构或公司都装配了安防系统，现有安防系统大都仅仅安装了图像摄像装置，图像摄像装置将图像传递到安保中心，由监视人员时刻监视，但监视区域有限，不能完全监控，且依靠人力监控，易出现盲区；有的安防系统安装了烟雾感应器，但烟雾感应器的误报率较大，造成人力、物力损失，增加防范火灾的成本。With the development of society, people pay more and more attention to fires, because once a fire occurs, it will be accompanied by material loss; the several fires that have occurred so far have suffered huge economic damage to varying degrees.

Complete monitoring, and relying on human monitoring, is prone to blind spots; some security systems are equipped with smoke sensors, but the false alarm rate of smoke sensors is relatively high, resulting in manpower and material losses, and increasing the cost of fire prevention.
