摘　　要：从家用燃气报警器的工作流程出发,分析得出家用燃气报警器误报的原因有传感器原因、硬件电路原因和软件处理程序原因,提出传感器抗干扰性能差是导致报警器误报的最主要原因。选用抗干扰性能好的传感器是降低误报率最直接有效的手段。针对使用抗干扰性能好的传感器会增加成本的问题,提出在选用抗干扰性能不高的传感器时,可通过提高报警设定值、增加响应时间和接入智慧厨房系统的方法来降低家用燃气报警器误报率。Starting from the working process of domestic gas alarm,the causes of false alarm of domestic gas alarm are analyzed,including sensor,hardware circuit and software processing program causes.It is proposed that poor anti-interference performance of sensor is the main causes of false alarm of domestic gas alarm.The most direct and effective means to reduce the false alarm rate is to select a sensor with good anti-interference performance.Aiming at the problem that using sensors with good anti-interference performance will increase the costs,it is proposed that when selecting sensors with low anti-interference performance,the false alarm rate of domestic gas alarm can be reduced by increasing the alarm setting value,increasing the response time and connecting to the smart kitchen system.
