一般地,厨房内会设有煤矿井下检测方法,现有技术中,对于烟气检测的灵敏度较差,而且检测效果不明显,不能及时排放火灾气体。
本发明内容
本发明旨在解决上述现有技术存在的问题之一,提供一种煤矿井下检测方法,该检测方法检测灵敏,安全可靠,结构简单,能及时排放火灾气体。
为了实现上述目的,本发明提供一种煤矿井下检测方法,包括:
S10:检测煤矿井下内的火灾气体浓度;
S20:根据检测到的所述火灾气体浓度进行判断控制,
当所述煤矿井下内火灾气体浓度大于或等于气体浓度阈值时,产生报警。
另外,根据本发明的煤矿井下检测方法,还可以具有如下技术特征:
进一步地,所述步骤S20包括甲烷传感器,所述甲烷传感器用于检测所述煤矿井下内甲烷的浓度,在所述甲烷浓度大于或等于所述甲烷阈值时产生报警信号。
进一步地,所述步骤S20包括二氧化碳传感器,所述二氧化碳传感器用于检测所述煤矿井下内二氧化碳的浓度,在所述二氧化碳浓度大于或等于所述二氧化碳阈值时产生报警信号。
优选地,所述步骤S20中还包括当所述二氧化碳浓度大于或等于所述二氧化碳阈值时,对所述煤矿井下进行喷淋。
附图说明
图1为煤矿井下检测方法的结构原理图。
具体实施方式
下面结合附图对本发明作进一步说明。
根据本发明的一种煤矿井下检测方法,包括如下步骤:
S10:检测煤矿井下内的火灾气体浓度;
S20:根据检测到的所述火灾气体浓度进行判断控制,
当所述煤矿井下内火灾气体浓度大于或等于气体浓度阈值时,产生报警。
进一步地,所述步骤S20包括甲烷传感器,所述甲烷传感器用于检测所述煤矿井下内甲烷的浓度,在所述甲烷浓度大于或等于所述甲烷阈值时产生报警信号。
进一步地,所述步骤S20包括二氧化碳传感器,所述二氧化碳传感器用于检测所述煤矿井下内二氧化碳的浓度,在所述二氧化碳浓度大于或等于所述二氧化碳阈值时产生报警信号。
优选地,所述步骤S20中还包括当所述二氧化碳浓度大于或等于所述二氧化碳阈值时,对所述煤矿井下进行喷淋。
优选地,所述步骤S20中还包括蜂鸣器,当所述火灾气体浓度大于或等于气体浓度阈值时,以控制所述蜂鸣器产生报警。
也就是说,首先对于煤矿井下的火灾气体浓度进行检测,当所述煤矿井下内甲烷气体浓度大于或等于甲烷浓度阈值时,产生报警;同时对于煤矿井下的火灾气体浓度进行检测,当所述煤矿井下内二氧化碳气体浓度大于或等于二氧化碳浓度阈值时,产生报警,说明井下发生火灾,并同时对煤矿井下进行喷淋处理。
以上所述仅是本发明的示范性实施方式,而非用于限制本发明的保护范围,本发明的保护范围由所附的权利要求确定。
本领域技术人员可以理解的是,上文中描述的本发明的多个实施例中的各个特征可以相应地省去、添加或者以任意方式组合。并且,本领域技术人员能够想到的简单变换方式以及对现有技术做出适应性和功能性的结构变换的方案,都属于本发明的保护范围。
虽然已经参考各种实施例示出和描述了本发明,但本领域技术人员应当理解的是,可以在其中做出形式和细节上的各种改变,而不背离由随附的权利要求所限定的本发明的范围。
