摘要:

为了减小电器火灾给人们的生命财产带来的损失,需要有效的电气火灾报警系统；提出了一种新型的综合电气火灾报警系统,该系统以51单片机作为核心处理芯片,利用温度传感器和红外火焰传感器协同监测环境状况;同时,系统利用了步进电机不断调整传感器的探测方位,消除了系统监测的死角,实现了全方位、高灵敏度火灾预警;该系统具有抗干扰能力强,灵敏度较高,实时性好、成本低等优点,满足火灾易发区的火灾报警需求;实验结果表明,该系统实现了对各种电器火灾的实时监测,检测灵敏度及准确率高,对预防火灾和消防救援具有重要的意义。

Abstract:

In order to reduce loss of people's life and property caused by electrical fire, the effective electrical fire alarm system is urgently needed. A new type of comprehensive fire alarm system is proposed which takes 51 single-chip microcomputer as the core processing chip. The system makes use of temperature sensors and infrared flame sensors to monitor environmental conditions. At the same time, it utilizes a stepper motor to adjust the detection range of sensors to eliminate the system monitoring blind angle. The system can realize the all-round, high sensitivity fire warning. It has strong anti-interference capability, high sensitivity, good real-time performance, low cost and etc. It can meet the fire alarm requirements of fire prone area. Experimental results show that this system can realize the real-time monitoring of various electrical fires. The detection sensitivity and accuracy of the system is high. And it has important significance to prevent fire and fire rescue.
