摘要
本文介绍了一种由单片机控制的新型便携式瓦斯检测报警装置。该装置通过采用瓦斯传感器间歇性工作模式,延长电源充电后的使用时间,降低电源充电频率,提高报警器的使用寿命。且电源由一般的电池改为锂电池,进一步缩小检测报警装置的体积,实现了报警装置的真正便携。
A new portable gas detect ＆ alarm device which is controlled by Single Chip Micyoco is proposed in this paper. With utilization of intermittent working mode of gas sensor in this device, as a result, the battery power off time can be postponed. Then the charging frequency can be reduced. So the life of alarming device can be prolonged. Further more, the traditional battery is replaced by lithium battery. The volume of this device can be reduced ulteriorly, which also brings us the real portability of alarm device.
