附图说明
图1是本发明冰箱检测煤气浓度的方法的流程示意图。
具体实施方式
以下将结合附图所示的具体实施方式对本发明进行详细描述。但这些实施方式并不限制本发明，本领域的普通技术人员根据这些实施方式所做出的结构、方法、或功能上的变换均包含在本发明的保护范围内。
如图1所示，本发明提供一种冰箱检测煤气浓度的方法，所述方法在发现煤气出现泄漏后，通过检测煤气泄漏量、厨房空间大小、厨房门开启角度和厨房窗户的开启角度，来计算厨房煤气的浓度，从而根据不同的煤气浓度采取不同的措施。需要说明的是，可以通过检测煤气管道是否出现异常开口来判断是否出现煤气泄漏。所述方法包括：
获得泄漏的煤气量St，以及厨房的体积V，检测厨房门的开启角度α1和厨房窗户的开启角度α2；
根据所述V、α1、α2和St，计算煤气浓度Ct
步骤S100：获得泄漏的煤气量St，以及厨房的体积V，检测厨房门的开启角度α1和厨房窗户的开启角度α2。
煤气管道中设置有与冰箱进行数据交互的传感器，所述传感器能够获取煤气管道内的压力P和管道异常开口参数γ，所述管道异常开口参数γ表征管道穿孔、开裂或渗透等的程度参数，然后根据煤气量计算公式计算泄露的煤气量St，所述煤气量计算公式为：
Figure PCTCN2021096413-appb-000002
其中，所述参数k为燃气/煤气绝热指数，在理想情况下可近似常量。
需要说明的是，可以通过参数γ，判断是否出现煤气泄漏，当发现γ不为0时，从这个时刻开始计算煤气的泄漏量，所述t为距离煤气开始泄漏的时间间隔。
通过用户预先输入的厨房的长、宽和高，计算所述厨房的体积V。
所述厨房门和窗都设置有开启角度传感器，所述冰箱能够与所述开启角度传感器进行数据交互，从而获取厨房门的开启角度α1和窗户的开启角度α2。
步骤S200：根据所述V、α1、α2和St，计算煤气浓度Ct。
具体的，通过煤气泄漏量和厨房的体积，可以得到初始煤气浓度Ct1＝St/V。然后厨房门窗的开启角度对煤气浓度产生线性的影响，即总体煤气浓度Ct＝Ct1-(a1*α1*t+d1)-(a2*α2*t+d2)＝Ct1-(a1*α1+a2*α2)*t–d，其中所述a1、a2、d1、d2和d都为常量，其中d＝d1+d2，所述t为距离煤气开始泄漏的时间间隔。因此，所述煤气浓度计算公式为：
Ct＝St/V–(a1*α1+a2*α2)*t–d。
步骤S300：若所述煤气浓度超过最低预警值，启动煤气紧急关闭装置，切断煤气总开关，并启动厨房的通风装置。
在一个优选的实施方式中，所述方法还包括：
步骤S400：当所述煤气浓度超过最低预警值时，根据多个用户的相关信息以及不同相关信息的不同权重，计算优先提醒的用户，给所述优先提醒的用户发送煤气浓度超标提醒。
具体的，所述“计算优先提醒的用户，给所述优先提醒的用户发送煤气浓度超标提醒”具体包括：
步骤S410：所述相关信息包括用户的年龄、角色、身体健壮度以及与厨房的距离，根据每个用户的所述相关信息，计算每个用户的总权重。
所述“根据每个用户的所述相关信息，计算每个用户的总权重”具体包括：
获取每个用户的实际年龄a、角色r、身体强壮度b和与厨房的距离l；
根据所述年龄a选择对应的年龄权重Wa，其中，若a<＝30，a越大Wa权重越大，否则，a越小Wa越小。也可以为每个年龄段设定一个权重，根据具体的年龄落入的年龄段，选择对应的年龄权重。
根据不同的角色r选择不同的角色权重Wr，其中，角色权重的排序从大到小依次为：父亲、母亲、儿女、管家或保姆、保安或物业。
根据不同的身体健壮度b，选择不同的身体健壮度权重Wb，其中，身体健壮度权重的排序从大到小依次为：健壮、正常、瘦小、得病、残疾。
根据所述与厨房的距离l，选择对应的距离权重Wl，其中，l越大Wl越小。也可以将所述距离l分段，为每个段落设定一个权重，根据具体的距离l落入的距离段落，选择对应的距离权重。
每个用户的总权重W等于每个用户对应的年龄权重Wa、角色权重Wr、身体健壮度权重Wb和距离权重Wl之和，即W＝Wa+Wr+Wb+Wl。
进一步的，所述“获取每个用户的实际年龄a、角色r、身体强壮度b和与厨房的距离l”具体包括：
通过预先为每个用户输入的年龄，根据输入时间和现在的时间，计算每个用户的年龄a；
通过预先为每个用户输入的角色和身体健康状况，得到用户的实际角色r和身体健壮度b；
通过预先绑定的定位终端，获取用户与厨房的距离l。
步骤S420：将总权重排名前N的用户作为优先提醒的用户。
可以选取总权重排名前N的用户，作为优先提醒的用户，所述N为正整数。
然后可以给所述优先提醒的用户发送煤气浓度超标提醒，并通知用户已经关闭煤气总开关，防止煤气浓度进一步上升从而造成无法挽回的损失。
由于煤气总开关可能关闭失败，为了提醒用户谨慎处理，进一步的，所述方法还包括：
在启动煤气紧急关闭装置后，若检测到用户煤气浓度还在继续上升，根据多个用户的相关信息以及不同相关信息的不同权重，计算优先提醒的用户，给所述优先提醒的用户发送警报。
在一个具体的实施方式中，冰箱通过与设置在煤气管道中的传感器进行数据交互，所述传感器能够获取煤气管道内的压力P和管道异常开口参数γ，当发现发现煤气管道出现裂痕(即γ不为0)或者压力P异常时，判定煤气出现泄漏，并根据所述P和γ，通过煤气量计算公式得到煤气随时间的泄漏量St。然后根据预先输入的厨房尺寸得到厨房的空间大小V，以及根据设置在厨房门和厨房窗户上的角度传感器，得到厨房门的开启角度α1和厨房窗户的开启角度α2。最后，根据所述V、α1、α2和St，计算煤气浓度Ct，在所述煤气浓度Ct超过最低预警值时，启动煤气紧急关闭装置，切断煤气总开关，并启动所述厨房的通风装置。同时，计算优先提醒的用户，给所述优先提醒的用户发送煤气浓度超标和煤气总开关已关闭的提醒。需要说明的是，在启动煤气紧急关闭装置后，若检测到用户煤气浓度还在继续上升，还需要给所述优先提醒的用户发送煤气总开关关闭失败、煤气还在继续泄漏的警报。
本发明还提供一种电子设备，包括存储器和处理器，所述存储器存储有可在所述处理器上运行的计算机程序，所述处理器上设置有与煤气管道中的传感器进行数据交互的控制模块，所述控制模块还用于与厨房门的开启角度传感器和厨房窗户的开启角度传感器进行数据交互，所述控制模块还用于接收用户输入的数据。所述处理器执行所述程序时实现上述所述冰箱检测煤气浓度的方法中的任意一个步骤，也就是说，实现上述所述冰箱检测煤气浓度的方法中任意一个技术方案中的步骤。
本发明还提供一种冰箱，所述冰箱包含上述所述的电子装置。
