摘　　要：目前一氧化碳中毒和燃气泄漏引起爆炸事件时有发生,而现有的报警系统功能较为单一,只能采取现场声光报警和短信提示,并且价格较高使其未能普及。针对以上情况,设计了一种基于SIM900A和STM32嵌入式处理器的燃气报警装置,该装置可以检测现场燃气、一氧化碳、烟雾以及温度参数,当检测值高于设定值后及时发出声光报警,启动自有排风装置和外置的大型排风装置,并同时向存储于SIM卡中的多组电话号码发送短信,而后依次拨打存储的电话号码直到有人接听,语音告知其危险情况。装置配备大容量锂电池,遇到突发停电情况后可以自动切换电源,提供持续监控。The carbon monoxide poisoning and explosion incidents caused by gas leakage occur frequently,so only the field sound?light alarm and SMS reminder can be adopted because the function of the existing alarm system is somewhat simple.Even though it can reduce the incidents greatly,it isn′t popularized due to its high price. Aiming at the above situations,a gas alarm device based on SIM900A and STM32 embedded processor was designed. The device can detect the field gas,carbon mo?noxide,smog and temperature parameters. When the detected value is higher than the set value,the device gives the sound?light alarm,starts the internal air exhaust device and external large?scale air exhaust device,sends the short massage to the mul?tigroup phone numbers stored in SIM card,and calls the stored phone numbers successively to notice the dangerous situationwith the voice until someone answers the phone. The device is equipped with a large?capacity lithium battery,and can automati?cally switch the power supply and provide the continuous monitoring after the sudden power failure.
