摘　　要：火灾给人民的生命和财产安全带来极大的威胁,其造成的各方面损失无法估量,对生态平衡造成的破坏几乎不可逆转,因此,各个国家都投入大量的人力、财力,试图通过先进的技术方法防止大范围火灾的发生。文中设计了一种基于51单片机并结合手机APP实时监控的火灾报警监测系统,以51单片机为主控,利用温度传感器和烟雾传感器准确检测场所内的实时环境并将数据通过WiFi模块传输到终端进行监测;各环境参数值大于等于预先设定的报警数值时会进行声光报警,提醒场所人员和监测人员采取紧急应对措施。该系统注重在中小型生活场所中的可推广性,安装方便、操作简单且价格低廉,为中小型场所生活民众的安全提供了保障,并为相关火灾报警监测系统设计提供了参考。Fire poses a great threat to the safety of people′s lives and property.The losses caused by fire are incalculable and the damage to the ecological balance is almost irreversible.Therefore,all countries have invested a lot of human and financial resources to try to prevent the occurrence of large⁃scale fire with advanced technologies and methods.On the basis of 51 single⁃chip microcomputer(SCM),a fire alarm monitoring system in combination with mobile phone APP real⁃time monitoring is designed.The 51 SCM is used as the main control.The temperature sensor and smoke sensor are used to accurately detect the real⁃time environment in the place and transmit the data to the terminal by the WiFi module for monitoring.When the value of each environment parameter is greater than or equal to the preset alarm value,an audible and visual alarm will be issued to remind the site personnel and monitoring personnel to take emergency response measures.The system lays emphasis on the popularization in small and medium⁃sized living places,and has the advantages of easy installation,simple operation and low price.Therefore,it provides a guarantee for the safety of people living in small and medium⁃sized places and a reference for the design of relevant fire alarm and monitoring system.
