现有技术通过将当前状态下加热装置的电阻值与预设的电阻阈值进行比较，或是通过加热过程中加热装置的电阻变化值与预设的变化阈值进行比较，判断气溶胶雾化装置是否出现不良状态，但是以上方法均存在误判的情况，进而影响检测的准确性。
因此，如何设计出一种可有效解决上述技术问题的检测方法,成为了亟待解决的技术问题。
 发明内容
本发明旨在至少解决现有技术或相关技术中存在的技术问题之一。
为此，本发明的第一方面提出了一种故障检测方法。
本发明的第二方面提出了一种故障检测装置。
本发明的第三方面提出了一种故障检测装置。
本发明的第四方面提出了一种可读存储介质。
本发明的第五方面提出了一种气溶胶雾化装置。
有鉴于此，本发明的第一方面提出了一种故障检测方法，应用于气溶胶雾化装置，气溶胶雾化装置包括加热装置，用于加热雾化气溶胶产生基质，故障检测方法包括：获取加热装置的第一阻值，第一阻值为加热装置在运行过程中电阻处于稳态状态下的阻值；获取加热装置在当前运行过程中的第二阻值；根据第一阻值和第二阻值，确定气溶胶雾化装置处于故障状态。
本发明限定的故障检测方法可对气溶胶雾化装置的故障进行检测，气溶胶雾化装置包括加热装置，加热装置通过对气溶胶雾化装置中的气溶胶产生基质加热雾化，使气溶胶产生基质生成气溶胶。故障检测方法通过分别获取加热装置的第一阻值以及第二阻值，并通过比较第一阻值以及第二阻值判断气溶胶雾化装置是否处于故障状态。
需要说明的是，第一阻值为加热装置的稳态阻值，其中，第一阻值包括历史运行记录中的稳态阻值，即历史稳态阻值。第一阻值还包括当前运行过程中的稳态阻值，即当前稳态阻值。在加热装置处于运行状态的过程中，加热装置的阻值受到加热装置的温度影响，会在运行开始阶段快速上升，然后保持稳态，该稳态状态的阻值即为稳态阻值。
第二阻值指的是当下加热装置运行的加热过程中加热装置的电阻阻值。
具体来说，气溶胶雾化装置在运行过程中，读取加热装置在稳态阶段的第一阻值，以及获取当前运行过程中的第二阻值。根据第一阻值和第二阻值，对气溶胶雾化装置是否存在故障进行检测。
其中，气溶胶雾化装置的故障包括硬件故障，还包括气溶胶雾化基质的剩余量过少。由于气溶胶雾化装置的剩余量过少，或气溶胶雾化装置的硬件出现故障，均会导致加热装置的电阻值发生较大变化，通过将当前运行过程中的第二阻值与加热装置的稳态阶段的第一阻值进行比较，能够准确对气溶胶雾化装置存在故障进行检测。
本发明限定的故障检测方法，通过将在溶胶雾化装置运行过程中，根据加热装置的电阻处于稳态状态下的第一阻值，以及当前运行过程中的第二阻值，对气溶胶发生装置是否存在故障进行检测，实现了对加热装置当前运行过程中是否存在故障进行检测，避免了由于加热装置故障对生成气溶胶造成的不良影响，相比于相关技术中的检测方式，本发明采用了电阻处于稳态状态下的第一阻值进行检测，提高了检测的准确性。
另外，本发明提供的上述实施例中的故障检测方法还可以具有如下附加技术特征：
在上述技术方案中，第一阻值为历史运行记录中电阻处于稳态状态下的阻值，获取加热装置的第一阻值，包括：确定历史运行记录中的第一稳态阶段；
获取第一稳态阶段中的多个第三阻值；根据多个第三阻值，确定第一阻值；其中，第一阻值包括以下任一项：多个第三阻值的算术平均值、多个第三阻值的中位数、多个第三阻值的滚动平均值。
需要说明的是，在气溶胶雾化装置存在历史运行记录的情况下，则获取历史记录中的稳态阻值，即第一阻值为历史稳态阻值。
在该技术方案中，根据加热装置在历史运行记录中的第一稳态阶段的多个第三阻值，能够确定该第一稳态阶段对应的第一阻值。
需要说明的是，第一稳态阶段为历史运行记录中，加热装置的电阻值处于稳定状态下的运行阶段，即加热装置的电阻值在第一稳态阶段下的变化值小于变化阈值。第三阻值为加热装置运行在第一稳态阶段下的电阻值。第一阻值可选为多个第三阻值的滚动平均值、算术平均值或中位数，本发明在此不做限定，可根据实际需求进行选择。
本发明根据第一稳态阶段的多个第三阻值，能够确定该历史记录对应的第一阻值，由于该第一阻值可选为多个第三阻值的算术平均值、滚动平均值或中位数，故该第一阻值能够代表第一稳态阶段中加热装置的电阻值，从而保证了
后续根据第一阻值和第二阻值判断气溶胶雾化装置是否存在故障的准确性。
在上述任一技术方案中，确定历史运行记录中的第一稳态阶段，包括：获取历史运行记录的第一起始时刻和第一结束时刻；根据第一起始时刻和第一预设时长，确定第二起始时刻，第二起始时刻为第一稳态阶段的起始时刻；根据第一结束时刻和第二预设时长，确定第二结束时刻，第二结束时刻为第一稳态阶段的结束时刻；根据第二起始时刻和第二结束时刻，确定第一稳态阶段。在该技术方案中，在确定历史运行记录中的第一稳态阶段的过程中，读取历史记录中的完整的运行阶段。并根据第一预设时长和第二预设时长选取完整的运行阶段中的第一稳态阶段。
其中，第一预设时长即加热装置由第一起始时刻达到第一稳态阶段所用的时长。第二预设时长即加热装置由结束第一稳态阶段到结束加热过程所用的时长。
具体来说，根据第一预设时长，以及历史记录中的完整的运行阶段的第一起始时刻，能够确定第二起始时刻，第二起始时刻晚于第一起始时刻。根据第
二预设时长，以及历史运行记录中的完整的运行阶段的第一结束时刻，能够确定第二结束时刻，第二结束时刻早于第一结束时刻。
本发明通过预设的第一预设时长和第二预设时长，能够准确确定历史运行记录中的完整的运行阶段中的第一稳态阶段，保证了得到第一阻值的均处于历史运行记录中的稳态阻值，进而提高了对气溶胶雾化装置是否存在故障判断的
准确性。
在上述任一技术方案中，确定历史运行记录中的第一稳态阶段，包括：根据多个第四阻值和历史运行记录的历史运行时长，确定阻值变化曲线；将阻值变化曲线的曲线斜率达到预设斜率的时刻，作为第三起始时刻，第三起始时刻为第一稳态阶段的起始时刻；获取历史运行记录的第三结束时刻；根据第三结
束时刻和第三预设时长，确定第四结束时刻，第四结束时刻为第一稳态阶段的结束时刻；根据第三起始时刻和第四结束时刻，确定第一稳态阶段。
在该技术方案中，获取历史运行记录中的多个第四阻值和历史运行记录历史运行时长，并据此绘制阻值变化曲线。阻值变化曲线的曲线斜率随时间发生变化，在检测到曲线斜率达到预设斜率的情况下，将该曲线斜率对应的时刻作为第三起始时刻。再根据第三结束时刻和第三预设时长，确定第四结束时刻，第四结束时刻在第三结束时刻之前。将第三起始时刻与第四结束时刻之间的运行阶段作为第一稳态阶段。
本发明通过绘制历史运行记录的阻值变化曲线，并基于阻值变化曲线的曲线斜率对加热装置是否运行至第一稳态阶段进行准确判定，即确定第三起始时
刻。并通过历史运行记录的第三结束时刻和第三预设时长确定第一稳态阶段的第四结束时刻，从而对第一稳态阶段的开始和结束的时间点进行准确确定，进一步提高了确定第一稳态阶段的准确性。在上述任一技术方案中，历史运行记录的数量为多个，第一阻值的数量与历史运行记录的数量相同；根据第一阻值和第二阻值，确定气溶胶雾化装置处于故障状态，包括：对多个第一阻值中
每个第一阻值与第二阻值进行差值计算，以得到多个第一阻值差值；确定多个第一阻值中对应的多个第一预设差值，多个第一预设差值与多个第一阻值对应的加热装置的运行时刻相对应；基于多个第一阻值差值中任一第一阻值差值大于相应的第一预设差值，确定气溶胶雾化装置处于故障状态。
在该技术方案中，在气溶胶雾化装置存在多个历史运行记录的情况下，根据多个第一阻值与第二阻值的多个阻值差值，判断气溶胶雾化装置是否处于故障状态。
在气溶胶雾化装置存在多个历史运行记录的情况下，获取每个历史运行记录中的第一阻值，第一阻值的数量也为多个，且第一阻值的数量与历史运行记录的数量相同。将多个第一阻值分别与第二阻值进行差值计算，以得到多个第一阻值差值，并将多个第一阻值差值与相应的第一预设差值进行比较。在检测到多个第一阻值差值中的任一个第一阻值差值大于相应的第一预设差值的情况下，则判定气溶胶雾化装置存在故障。
需要说明的是，第一预设差值为提前预设的预设值，该第一预设差值与多个第一阻值对应的加热装置的运行时刻相对应。具体来说，在设置第一预设差值时，将多个第一预设差值与距离当前运行时刻不同时长的历史运行时刻进行关联对应。
示例性地，第一预设差值的数量为 a、b、c。将距离当前运行时刻最近的历史运行时刻对应设置第一预设差值 a，按照距离当前运行时刻的时长由短至长的关系，将第一预设差值 b、c 对应设置不同的历史运行时刻。
本发明限定的故障检测方法，通过设置多个历史运行记录以及对应的第一阻值，并通过分别计算每个第一阻值与第二阻值之间的第一阻值差值，将多个第一阻值差值与对应的第一预设差值对比，在多个第一阻值差值中存在大于相应的第一预设差值的第一阻值差值的情况下，就判定存在故障，实现了对气溶胶雾化装置工作状态的检测以及气溶胶雾化装置是否处于故障状态的判断，提高了检测的容差性，避免了误差对检测方法造成的影响，进而提高了检测方法的准确性。
在上述任一技术方案中，获取多个第一阻值中对应的多个第一预设差值，包括：获取第一预设差值序列，第一预设差值序列包括多个第一预设差值；获
取多个第一阻值中每个第一阻值对应的历史运行记录的运行时刻；根据多个运行时刻，对多个第一阻值进行排序，以得到第一阻值序列；将第一预设差值序列与第一阻值序列建立映射关系，以确定每个第一阻值对应的第一预设差值。
需要说明的是，第一预设差值为气溶胶雾化装置在出厂前提前设置得到的，故第一预设差值的数量为固定数量。第一阻值为历史运行记录中的第一稳态阶段的阻值，即第一阻值与历史运行记录向相对应，在历史运行记录的数量为多个的情况下，则第一阻值的数量为多个，由于历史运行记录的数量为气溶胶雾化装置实际运行的次数，故第一阻值的数量为变化数量。
第一预设差值序列为按照多个第一预设差值之间的大小关系排列得到的序列。第一阻值序列为按照第一阻值对应的历史运行记录的运行时刻进行排列得到的序列。将第一预设差值序列与第一阻值序列建立对应关系后，能够确定每个第一阻值对应的第一预设差值。
具体来说，在第一预设差值序列中的第一预设差值的数量大于等于第一阻值序列中的第一阻值的数量的情况下，则对每个第一阻值均设置对应的第一预设差值。在第一预设差值序列中的第一预设差值的数量小于第一阻值序列中的第一阻值的数量的情况下，则对部分第一阻值设置对应的第一预设差值，保证每个第一预设差值对应一个第一阻值。
示例性地，第一预设差值序列中包括五个第一预设差值，分别为  A、B、
C、D、E。第一阻值序列中包括三个第一阻值，分别为 a、b、c。则对第一阻值序列中的三个第一阻值分别设置相应的第一预设差值，a 对应 A，b 对应 B，c 对应 C。随着历史运行记录数量的增长，第一阻值序列中包括六个第一阻值，分别为 a、b、c、e、f、g，则对第一阻值序列中的五个第一阻值分别设置相应的第一预设差值，b 对应 A，c 对应 B，e 对应 C，f 对应 D，g 对应 E。
本发明中，通过提前设置的第一预设差值序列，对多个第一阻值配置相应的第一预设差值，在历史运行记录增多的情况下，能够对多个第一预设差值对应的第一阻值进行更新，实现了提高获取第一阻值对应的第一预设差值的准确性。
在上述任一技术方案中，第一阻值对应的运行时刻距离当前时刻的时间差值与第一阻值对应的第一预设差值正相关。
在该技术方案中，受加热装置的物理特性影响，随着加热装置的运行，则加热装置的电阻值逐渐增大。故第一差值序列中的第一预设差值越小的对应的第一阻值的历史运行记录的运行时刻距离当前时刻越近。
本发明中通过设置第一阻值和第一差值序列之间的关系，能够提高获取第一阻值对应的第一预设差值的准确性。
在上述任一技术方案中，第一阻值为当前运行过程中电阻处于稳态状态下的阻值；
获取加热装置的第一阻值，包括：获取加热装置在当前运行过程中的多个第五阻值，第五阻值为当前运行过程中的稳态阶段的阻值；根据多个第五阻值，确定第一阻值；
其中，第一阻值包括以下任一项：多个第四阻值的算术平均值、多个第四阻值的中位数、多个第四阻值的滚动平均值。
需要说明的是，在气溶胶雾化装置不存在历史运行记录的情况下，则当前运行过程中的稳态阻值，即第一阻值为当前稳态阻值。
在该技术方案中，在获取第一阻值（当前稳态阻值）的过程中，获取加热装置在当前运行过程中的多个第五阻值，第五阻值为加热装置运行在稳态阶段的阻值。
在确定电子设备所处的当前运行过程已经进入稳态阶段，故采集稳态阶段中的第五阻值，并基于第五阻值确定当前稳态阻值（第一阻值）。
第一阻值可选为多个第五阻值的滚动平均值、算术平均值或中位数，本发明在此不做限定，可根据实际需求进行选择。
本发明根据当前的稳态阶段的多个第五阻值，能够确定当前运行过程中的
第一阻值，由于该第一阻值可选为多个第五阻值的算术平均值、滚动平均值或中位数，故该第一阻值能够代表当前运行过程中的稳态阶段中加热装置的电阻值，从而保证了后续根据第一阻值和第二阻值判断气溶胶雾化装置是否存在故障的准确性。
在上述任一实施例中，获取加热装置在当前运行过程中的稳态阶段的多个第五阻值，包括：
获取当前运行过程中的第五起始时刻、当前运行时刻及当前运行时长；
在当前运行时长大于第四预设时长的情况下，根据第五起始时刻和第四预设时长，确定第六起始时刻，第六起始时刻为当前运行过程中的稳态阶段的起始时刻；
根据当前运行时刻和第五预设时长，确定第六结束时刻；
在第六结束时刻晚于第六起始时刻的情况下，获取第六起始时刻至第六结束时刻之间的多个第五阻值。
其中，第四预设时长即加热装置由第五起始时刻达到稳态运行阶段所用的时长。在当前运行时长大于第四预设时长的情况下，则确定加热装置进入到稳态阶段，再根据当前运行过程中的第五起始时刻和第四预设时长确定第六起始时刻，该第六起始时刻即为稳态阶段起始时刻。
由于当前运行时刻在稳态阶段起始时刻之后，无法确定当前运行时刻之后是否会立即停止运行，为排除干扰，则需要排除当前运行时刻之前一段时间内的干扰情况，也就是需要根据当前运行时刻和第五预设时长，确定第六结束时刻。在第六结束时刻晚于第六起始时刻的情况下，说明当前运行过程中稳态阶段运行时间大于零，则将第六起始时刻至第六结束时刻之间的运行阶段作为稳态运行阶段。
在确定当前运行过程中的稳态运行阶段之后，获取当前运行过程中的稳态运行阶段中的多个第五阻值。
需要说明的是，如果当前运行时长小于等于第四预设时长，则说明当前运行过程并未进入稳态阶段，则不能依据当前运行过程确定第一阻值。如果第六结束时刻早于第六起始时刻，则说明当前运行过程虽然已进入稳态阶段，但为了排除干扰，稳态阶段运行时间被视为零，这种情况下，也不能根据当前运行
过程确定第一阻值。
本发明通过预设的第四预设时长和第五设时长，能够准确确定当前运行过程中的稳态运行阶段，并根据获取此阶段内的多个第五阻值，以确定稳态阶段中的第一阻值，提高了确定第一阻值的准确性。
在上述任一实施例中，获取加热装置在当前运行过程中的稳态阶段的多个第五阻值，包括：
根据多个第六阻值和当前运行过程的运行时长，确定阻值变化曲线；
将阻值变化曲线的曲线斜率达到预设斜率的时刻，作为第七起始时刻，第七起始时刻为当前运行过程中的稳态阶段的起始时刻；
获取当前运行过程中的当前运行时刻；
根据当前运行时刻和第六预设时长，确定第七结束时刻；
在第七结束时刻晚于第七起始时刻的情况下，获取第七起始时刻至第七结束时刻之间的多个第五阻值。
在该实施例中，获取当前运行过程的多个第六阻值和当前运行过程的运行
时长，并据此绘制阻值变化曲线。阻值变化曲线的曲线斜率随时间发生变化，在检测到曲线斜率达到预设斜率的情况下，将该曲线斜率对应的时刻作为第七起始时刻，该第七起始时刻即为稳态阶段起始时刻。
由于当前运行时刻在稳态阶段起始时刻之后，无法确定当前运行时刻之后是否会立即停止运行，为排除干扰，则需要排除当前运行时刻之前一段时间内的干扰情况，也就是需要根据当前运行时刻和第六预设时长，确定第七结束时刻。在第七结束时刻晚于第七起始时刻的情况下，说明当前运行过程中稳态阶段运行时间大于零，则将第七起始时刻至第七结束时刻之间的运行阶段作为稳态运行阶段。
在确定当前运行过程中的稳态运行阶段之后，获取当前运行过程中的稳态
运行阶段中的多个第五阻值。
需要说明的是，如果阻值变化曲线的曲线斜率未达到预设斜率，则说明当前运行过程并未进入稳态阶段，则不能依据当前运行过程确定第一阻值。如果第七结束时刻早于第七起始时刻，则说明当前运行过程虽然已进入稳态阶段，但为了排除干扰，稳态阶段运行时间被视为零，这种情况下，也不能根据当前
运行过程确定第一阻值。
本发明通过绘制历史运行记录的阻值变化曲线，并基于阻值变化曲线的曲线斜率和第六设时长，能够准确确定当前运行过程中的稳态运行阶段，并根据获取此阶段内的多个第五阻值，以确定稳态阶段中的第一阻值，提高了确定第一阻值的准确性。

需要说明的是，第一阻值为加热装置的稳态阻值，其中，第一阻值包括历
史运行记录中的稳态阻值，即历史稳态阻值。第一阻值还包括当前运行过程中
的稳态阻值，即当前稳态阻值。在加热装置处于运行状态的过程中，加热装置的阻值受到加热装置的温度影响，会在运行开始阶段快速上升，然后保持稳态，该稳态状态的阻值即为稳态阻值。第二阻值指的是当下加热装置运行的电阻阻值，具体而言，第二阻值可以是瞬态阻值，也可以是极短时间段内的多个瞬态阻值的算术平均值、中位值或滚动平均值。极短时间可以是 1-100 毫秒，可选5-30 毫秒。
具体来说，气溶胶雾化装置在运行过程中，读取加热装置在的稳态阶段的第一阻值，以及获取当前运行过程中的第二阻值。根据第一阻值和第二阻值，对气溶胶雾化装置是否存在故障进行检测。
其中，气溶胶雾化装置的故障包括硬件故障，还包括气溶胶雾化基质的剩
余量过少。由于气溶胶雾化装置的剩余量过少，或气溶胶雾化装置的硬件出现故障，均会导致加热装置的电阻值发生较大变化，通过将当前运行过程中的第二阻值与加热装置的稳态阶段的第一阻值进行比较，能够准确对气溶胶雾化装置存在故障进行检测。
本发明限定的故障检测方法，通过将在气溶胶雾化装置运行过程中，根据
加热装置的电阻处于稳态状态下的第一阻值，以及当前运行过程中的第二阻值，对气溶胶发生装置是否存在故障进行检测，实现了对加热装置当前运行过程中 是否存在故障进行检测，避免了由于加热装置故障对生成气溶胶造成的不良影 响，相比于相关技术中的检测方式，本发明采用了电阻处于稳态状态下的第一阻值进行检测，提高了检测的准确性。

第一阻值可选为多个第三阻值的滚动平均值、算术平均值或中位数，本发明在此不做限定，可根据实际需求进行选择。
本发明根据第一稳态阶段的多个第三阻值，能够确定该历史记录对应的第一阻值，由于该第一阻值可选为多个第三阻值的算术平均值、滚动平均值或中位数，故该第一阻值能够代表第一稳态阶段中加热装置的电阻值，从而保证了后续根据第一阻值和第二阻值判断气溶胶雾化装置是否存在故障的准确性。

步骤408，根据第二起始时刻和第二结束时刻，确定第一稳态阶段。
在该实施例中，在确定历史运行记录中的第一稳态阶段的过程中，读取历史记录中的完整的运行阶段。并根据第一预设时长和第二预设时长选取完整的运行阶段中的第一稳态阶段。
其中，第一预设时长即加热装置由第一起始时刻达到第一稳态阶段所用的时长。第二预设时长即加热装置由结束第一稳态阶段到结束加热过程所用的时长。
具体来说，根据第一预设时长，以及历史记录中的完整的运行阶段的第一

步骤 606，获取历史运行记录的第三结束时刻；
步骤 608，根据第三结束时刻和第三预设时长，确定第四结束时刻，第四结束时刻为第一稳态阶段的结束时刻；
步骤610，根据第三起始时刻和第四结束时刻，确定第一稳态阶段。
在该实施例中，获取历史运行记录中的多个第四阻值和历史运行记录历史运行时长，并据此绘制阻值变化曲线。第四阻值为加热装置在历史运行记录中的采样时间点的瞬态电阻值。阻值变化曲线的曲线斜率随时间发生变化，在检测到曲线斜率达到预设斜率的情况下，将该曲线斜率对应的时刻作为第三起始
时刻。再根据第三结束时刻和第三预设时长，确定第四结束时刻，第四结束时刻在第三结束时刻之前。将第三起始时刻与第四结束时刻之间的运行阶段作为第一稳态阶段。
本发明通过绘制历史运行记录的阻值变化曲线，并基于阻值变化曲线的曲线斜率对加热装置是否运行至第一稳态阶段进行准确判定，即确定第三起始时刻。并通过历史运行记录的第三结束时刻和第三预设时长确定第一稳态阶段的第四结束时刻，从而对第一稳态阶段的开始和结束的时间点进行准确确定，进一步提高了确定第一稳态阶段的准确性。
如图7 所示，在上述任一实施例中，历史运行记录的数量为多个，第一阻值的数量与历史运行记录的数量相同；
根据第一阻值和第二阻值，确定气溶胶雾化装置处于故障状态，包括：步骤702，对多个第一阻值中每个第一阻值与第二阻值进行差值计算，以得到多个第一阻值差值；
步骤 704，确定多个第一阻值中对应的多个第一预设差值，多个第一预设差值与多个第一阻值对应的加热装置的运行时刻相对应；
步骤 706，基于多个第一阻值差值中任一第一阻值差值大于相应的第一预设差值，确定气溶胶雾化装置处于故障状态。
在该实施例中，在气溶胶雾化装置存在多个历史运行记录的情况下，根据多个第一阻值与第二阻值的多个阻值差值，判断气溶胶雾化装置是否处于故障状态。
在气溶胶雾化装置存在多个历史运行记录的情况下，获取每个历史运行记录中的第一阻值，第一阻值的数量也为多个，且第一阻值的数量与历史运行记录的数量相同。将多个第一阻值分别与第二阻值进行差值计算，以得到多个第一阻值差值，并将多个第一阻值差值与相应的第一预设差值进行比较。在检测到多个第一阻值差值中的任一个第一阻值差值大于相应的第一预设差值的情况下，则判定气溶胶雾化装置存在故障。
示例性地，历史运行记录的数量的取值范围为 3 至 10 次。
在气溶胶雾化装置出现故障的情况下，加热装置的实时阻值会逐步上升，需要检测多个历史运行记录的第一阻值，并根据多个第一阻值对是否存在故障进行检测。
如图8 所示，气溶胶物装置在第 8 次运行时，加热装置的阻值上升幅度出现明显变化。
需要说明的是，第一预设差值为提前预设的预设值，该第一预设差值与多个第一阻值对应的加热装置的运行时刻相对应。具体来说，在设置第一预设差值时，将多个第一预设差值与距离当前运行时刻不同时长的历史运行时刻进行关联对应。
示例性地，第一预设差值的数量为 a、b、c。将距离当前运行时刻最近的历史运行时刻对应设置第一预设差值 a，按照距离当前运行时刻的时长由短至长的关系，将第一预设差值 b、c 对应设置不同的历史运行时刻。
本实施例限定的故障检测方法，通过设置多个历史运行记录以及对应的第一阻值，并通过分别计算每个第一阻值与第二阻值之间的第一阻值差值，将多个第一阻值差值与对应的第一预设差值对比，在多个第一阻值差值中存在大于相应的第一预设差值的第一阻值差值的情况下，就判定存在故障，实现了对气溶胶雾化装置工作状态的检测以及气溶胶雾化装置是否处于故障状态的判断，提高了检测的容差性，避免了误差对检测方法造成的影响，进而提高了检测方法的准确性。
如图 9 所示，在上述任一实施例中，获取多个第一阻值中对应的多个第一预设差值，包括：
步骤 902，获取第一预设差值序列，第一预设差值序列包括多个第一预设差值；
步骤 904，获取多个第一阻值中每个第一阻值对应的历史运行记录的运行时刻；
步骤906，根据多个运行时刻，对多个第一阻值进行排序，以得到第一阻
值序列；
步骤 908，将第一预设差值序列与第一阻值序列建立映射关系，以确定每个第一阻值对应的第一预设差值。
需要说明的是，第一预设差值为气溶胶雾化装置在出厂前提前设置得到的，故第一预设差值的数量为固定数量。第一阻值为历史运行记录中的第一稳态阶段的阻值，即第一阻值与历史运行记录相对应，在历史运行记录的数量为多个的情况下，则第一阻值的数量为多个，由于历史运行记录的数量为气溶胶雾化装置实际运行的次数，故第一阻值的数量为变化数量。
第一预设差值序列为按照多个第一预设差值之间的大小关系排列得到的序列。第一阻值序列为按照第一阻值对应的历史运行记录的运行时刻进行排列得到的序列。将第一预设差值序列与第一阻值序列建立对应关系后，能够确定每个第一阻值对应的第一预设差值。
具体来说，在第一预设差值序列中的第一预设差值的数量大于等于第一阻值序列中的第一阻值的数量的情况下，则对每个第一阻值均设置对应的第一预设差值。在第一预设差值序列中的第一预设差值的数量小于第一 阻值序列中的第一阻值的数量的情况下，则对部分第一阻值设置对应的第一预设差值，保证每个第一预设差值对应一个第一阻值。
示例性地，第一预设差值序列中包括五个第一预设差值，分别为 A、B、 C、D、E。第一阻值序列中包括三个第一阻值，分别为 a、b、c。则对第一阻值序列中的三个第一阻值分别设置相应的第一预设差值，a 对应 A，b 对应 B，c 对应 C。随着历史运行记录数量的增长，第一阻值序列中包括六个第一阻值，分别为 a、b、c、e、f、g，则对第一阻值序列中的五个第一阻值分别设置相应的第一预设差值，b 对应 A，c 对应 B，e 对应 C，f 对应 D， g 对应 E。
本发明中，通过提前设置的第一预设差值序列，对多个第一阻值配置相应的第一预设差值，在历史运行记录增多的情况下，能够对多个第一预设差值对应的第一阻值进行更新，实现了提高获取第一阻值对应的第一预设差值的准确性。
在上述任一实施例中，第一阻值对应的运行时刻距离当前时刻的时间差值与第一阻值对应的第一预设差值正相关。
在该实施例中，受加热装置的物理特性影响，随着加热装置的运行，则加热装置的电阻值逐渐增大。故第一差值序列中的第一预设差值越小的对应的第一阻值的历史运行记录的运行时刻距离当前时刻越近。
本发明中通过设置第一阻值和第一差值序列之间的关系，能够提高获取第一阻值对应的第一预设差值的准确性。
如图10 所示，在上述任一实施例中，第一阻值为当前运行过程中电阻处于稳态状态下的阻值；
获取加热装置的第一阻值，包括：
步骤1002，获取加热装置在当前运行过程中的多个第五阻值，第五阻值为当前运行过程中的稳态阶段的阻值；
步骤1004，根据多个第五阻值，确定第一阻值；
其中，第一阻值包括以下任一项：多个第五阻值的算术平均值、多个第五阻值的中位数、多个第五阻值的滚动平均值。
需要说明的是，在气溶胶雾化装置不存在历史运行记录的情况下，则当前运行过程中的稳态阻值，即第一阻值为当前稳态阻值。
在该实施例中，在获取第一阻值（当前稳态阻值）的过程中，获取加热装置在当前运行过程中的多个第五阻值，第五阻值为加热装置运行在稳态阶段的采样时间点的瞬态电阻值。
在确定电子设备所处的当前运行过程已经进入稳态阶段，故采集稳态阶段中的第五阻值，并基于第五阻值确定当前稳态阻值（第一阻值）。
第一阻值可选为多个第五阻值的滚动平均值、算术平均值或中位数，本发明在此不做限定，可根据实际需求进行选择。
本发明根据当前的稳态阶段的多个第五阻值，能够确定当前运行过程中的
第一阻值，由于该第一阻值可选为多个第五阻值的算术平均值、滚动平均值或中位数，故该第一阻值能够代表当前运行过程中的稳态阶段中加热装置的电阻值，从而保证了后续根据第一阻值和第二阻值判断气溶胶雾化装置是否存在故障的准确性。
如图11所示，在上述任一实施例中，获取加热装置在当前运行过程中的稳态阶段的多个第五阻值，包括：
步骤1102，获取当前运行过程中的第五起始时刻、当前运行时刻及当前运行时长；
步骤 1104，在当前运行时长大于第四预设时长的情况下，根据第五起始时刻和第四预设时长，确定第六起始时刻，第六起始时刻为当前运行过程中的稳态阶段的起始时刻；
步骤 1106，根据当前运行时刻和第五预设时长，确定第六结束时刻； 步骤 1108，在第六结束时刻晚于第六起始时刻的情况下，获取第六起始时刻至第六结束时刻之间的多个第五阻值。
其中，第四预设时长即加热装置由第五起始时刻达到稳态运行阶段所用的
时长。在当前运行时长大于第四预设时长的情况下，则确定加热装置进入到稳态阶段，再根据当前运行过程中的第五起始时刻和第四预设时长确定第六起始时刻，该第六起始时刻即为稳态阶段起始时刻。
由于当前运行时刻在稳态阶段起始时刻之后，无法确定当前运行时刻之后是否会立即停止运行，为排除干扰，则需要排除当前运行时刻之前一段时间内
的干扰情况，也就是需要根据当前运行时刻和第五预设时长，确定第六结束时刻。在第六结束时刻晚于第六起始时刻的情况下，说明当前运行过程中稳态阶段运行时间大于零，则将第六起始时刻至第六结束时刻之间的运行阶段作为稳态运行阶段。
在确定当前运行过程中的稳态运行阶段之后，获取当前运行过程中的稳态
运行阶段中的多个第五阻值。
需要说明的是，如果当前运行时长小于等于第四预设时长，则说明当前运行过程并未进入稳态阶段，则不能依据当前运行过程确定第一阻值。如果第六结束时刻早于第六起始时刻，则说明当前运行过程虽然已进入稳态阶段，但为了排除干扰，稳态阶段运行时长被视为零，这种情况下，也不能根据当前运行过程确定第一阻值。
如图12 所示，T5 为当前运行过程的第五起始时刻，T8 为当前运行时刻，T6 为当前运行过程稳态阶段的起始时刻（第六起始时刻），T7 为当前运行过程稳态阶段的结束时刻（第六结束时刻）。T5 至 T6 为第四预设时长，T7 至T8 为第二预设时长，T5 至 T8 为当前运行时长。
本发明通过预设的第四预设时长和第五设时长，能够准确确定当前运行过程中的稳态运行阶段，并根据获取此阶段内的多个第五阻值，以确定稳态阶段中的第一阻值，提高了确定第一阻值的准确性。
如图 13所示，在上述任一实施例中，获取加热装置在当前运行过程中的
稳态阶段的多个第五阻值，包括：
步骤 1302，根据多个第六阻值和当前运行过程的运行时长，确定阻值变化曲线；
步骤 1304，将阻值变化曲线的曲线斜率达到预设斜率的时刻，作为第七起始时刻，第七起始时刻为当前运行过程中的稳态阶段的起始时刻；
步骤1306，获取当前运行过程中的当前运行时刻；
步骤 1308，根据当前运行时刻和第六预设时长，确定第七结束时刻； 步骤 1310，在第七结束时刻晚于第七起始时刻的情况下，获取第七起始时刻至第七结束时刻之间的多个第五阻值。
在该实施例中，获取当前运行过程的多个第六阻值和当前运行过程的运行时长，并据此绘制阻值变化曲线。第六阻值为加热装置在当前运行过程中的采样时间点的采样时间点的瞬态电阻值。阻值变化曲线的曲线斜率随时间发生变化，在检测到曲线斜率达到预设斜率的情况下，将该曲线斜率对应的时刻作为第七起始时刻，该第七起始时刻即为稳态阶段起始时刻。
由于当前运行时刻在稳态阶段起始时刻之后，无法确定当前运行时刻之后
是否会立即停止运行，为排除干扰，则需要排除当前运行时刻之前一段时间内的干扰情况，也就是需要根据当前运行时刻和第六预设时长，确定第七结束时刻。在第七结束时刻晚于第七起始时刻的情况下，说明当前运行过程中稳态阶段运行时间大于零，则将第七起始时刻至第七结束时刻之间的运行阶段作为稳
态运行阶段。
在确定当前运行过程中的稳态运行阶段之后，获取当前运行过程中的稳态运行阶段中的多个第五阻值。
需要说明的是，如果阻值变化曲线的曲线斜率未达到预设斜率，则说明当前运行过程并未进入稳态阶段，则不能依据当前运行过程确定第一阻值。如果第七结束时刻早于第七起始时刻，则说明当前运行过程虽然已进入稳态阶段，但为了排除干扰，稳态阶段运行时间被视为零，这种情况下，也不能根据当前运行过程确定第一阻值。
本发明通过绘制历史运行记录的阻值变化曲线，并基于阻值变化曲线的曲线斜率和第六预设时长，能够准确确定当前运行过程中的稳态运行阶段，并根据获取此阶段内的多个第五阻值，以确定稳态阶段中的第一阻值，提高了确定第一阻值的准确性。
在上述任一实施例中，故障检测方法还包括：在加热装置处于故障状态下，控制加热装置停止运行。在上述任一实施例中，故障检测方法还包括：在加热装置处于故障状态下，控制加热装置停止运行。
在该实施例中，当检测到加热装置处于故障状态时，通过控制加热装置停止运行，避免了由于加热装置的温度过高对生成气溶胶造成的不良影响，以及对加热装置电能的耗费，还可对用户进行提醒，减小了能源的损耗，提高了用户的使用体验。
