居室灭火中温度高是火灾的一项重要指症。以温度是否超限为基本依据,设计了一种居室火灾报警系统,论证了系统中几个重要部分的硬件结构和软件设计思路,为避免火灾报警系统误报和漏报,设计上采用实时显示温度,LED灯显示和蜂鸣器联合预警的配合方式,并对整体设计进行了仿真评估,仿真结果表明,系统完全能实现预期的设计效果。并具有一定的使用价值。 High temperature fire in the room is an important indicator of the fire. To the temperature is over the limit as the basic basis, a residential fire alarm system is designed to demonstrate several important parts of the system hardware structure and software design ideas, in order to avoid false alarm and false alarm system, the design uses real-time display Temperature, the combination of LED lamp and buzzer warning, and the overall design was simulated and evaluated. The simulation results show that the system can achieve the expected design results. And has a certain use value.
