基于STM8L151K4T6单片机设计一种多功能、低功耗报警系统,在具备传统烟雾报警功能的同时,增加有毒气体检测、实时温度测量以及火焰识别报警的功能,具备多信号处理能力。监测模块采集到的数据先进行A/D转换,再进行数据处理和算法分析,利用LoRa无线传输技术以及GPRS模块实现数据远距离传输。实验结果表明,独立式报警器待机电流仅为1~2μA的情况下,可以在很短的响应时间内对报警信号进行反馈,实时性高,监测精准度综合数据高达97.295%。
The system is a multi-functional and low-power alarm system based on STM8L151K4T6 microcontroller.It has the traditional smoke alarm function,and adds the functions of poisonous gas detection,real-time temperature measurement and flame recognition alarm.It has the ability of multi-signal processing.The data collected by the monitoring module is converted from analog to digitad,then processed and analyzed.Finally,LoRa wireless transmission technology and GPRS module are used to realize data transmission over a long distance.The experimental results show that when the standby current of the independent alarm is only 1~2 uA,the alarm signal can be fed back in a short response time,and the real-time performance is high.The comprehensive data of the monitoring accuracy is as high as 97.295%.
