摘　　要：针对在易燃易爆及有毒气体环境下实时准确监测CO气体浓度的需要,采用低功耗技术及本质安全技术设计了CO监测仪,通过电火花放电计算和热效应计算验证本安设计的可行性;低功耗的实测验证了CO监测仪的低功耗特性,设计方法也可推广到其他有毒有害气体的监测系统中。In order to meet the need that real-time and accurate monitoring the concentration of CO gas in explosive and toxic gas environment, the design of the intrinsic safety CO monitor with low power consumption was proposed by using the low power consumption technology and intrinsic safety technology. Through calculation of the electric spark discharge and heating calculation verify the feasibility of the intrinsic safety design. Low power experimental verified the low consumption characteristic of the CO monitor. The design method can also be extended to other poisonous and harmful gas monitoring system.
