火灾是人类社会经常遇到的一个灾害,它通常给人民群众带来生命和财产的损失;针对传统火灾报警器参数单一,易出现漏报、误报的问题,文章设计了一种基于多传感器信息融合的火灾报警器;该系统以温度传感器、CO浓度传感器和烟雾浓度传感器测量的现场参数为参考,通过比较器的比较送给单片机进行信息融合,当温度高度设定值时,蜂鸣器报警;在温度高于设定值,且CO和烟雾浓度高于设定值时,蜂鸣器报警并且LED灯闪烁,提示有可能有火灾发生;最终通过对系统的调试实现了对液晶显示器的显示控制和报警器的报警;仿真结果表明了系统能够及时准确的判断是否有火灾发生,具有较强的火灾预测和报警能力.%Fire is a common disaster in human society.It usually causes people to lose their lives and property.For the traditional fire detection technology is based on the single fire parameters and it causes false and failure alarm,so the paper focuses on the fire alarm system based on multi-sensor information fusion combining with the character of fire signal,a kind of fire alarm system of multi-sensor informa tion fusion is proposed in this paper.This fire alarm system fuses three sensor data including temperature,smoke and CO air.The parameters are presented to the single chip machine for information fusion through the comparator comparison.When the temperature is highly set,the buzzer alarm;When the temperature is higher than the set value,and the CO and smoke concentrations are higher than the set value,the buzzer alarms and the LED light flashes,indicating that there may be a fire.By the end of debugging,this system achieves to the control of LCD display and alarm warning.The simulations reveal that the system can makes timely and accurate judgment about whether there is fire.Therefore,it has the strong ability to make the fire prediction and alarm.
