具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
本公开主要针对现有技术中滤芯寿命确定结果的准确性较低的技术问题，提出一种滤芯寿命监测方法。
本公开实施例的滤芯寿命监测方法，通过在采用滤芯进行空气净化过程中，监测目标物质的浓度，并根据监测到的目标物质的浓度，确定滤芯寿命，其中，目标物质为滤芯对污染物质进行分解得到的。本公开中，根据目标物质的浓度，可以确定滤芯的净化能力和净化效果，进而根据净化能力或净化效果，可以确定滤芯寿命，由此，可以准确识别滤芯寿命，从而可以避免未正确识别滤芯寿命而导致的相关问题，例如可以避免寿命末期的滤芯仍然服役而导致净化性能下降的情况，或者可以避免未到寿命末期的滤芯被替换而造成资源浪费的情况。
下面参考附图描述本公开实施例的滤芯寿命监测方法、装置和空气净化设备。
图1为本公开实施例一所提供的滤芯寿命监测方法的流程示意图。
本公开实施例以该滤芯寿命监测方法被配置于滤芯寿命监测装置中来举例说明，该滤芯寿命监测装置可以应用于空气净化设备中，以使该空气净化设备执行滤芯寿命监测功能。其中，空气净化设备是指具有空气净化功能的相关设备，例如可以为空气净化器、空调等设备。
本公开实施例中，滤芯用于对污染物质进行分解得到目标物质。
可以理解的是，对于固体污染物(比如可吸入颗粒物PM10、PM2.5等)，在利用空气净化设备对其进行过滤时，主要利用滤芯对其进行吸附，以达到净化空气的目的，而对于气体污染物(比如甲醛、总挥发性有机物(Total Volatile Organic Compounds，简称TVOC)等)，可以利用滤芯对其进行分解，以得到目标物质。
因此，本公开实施例中，污染物质具体可以为气体污染物，例如甲醛、含氯挥发性有机物(Cl—VOCs)等等。滤芯可以对污染物质进行分解，得到目标物质，例如，滤芯可以对甲醛进行分解，得到二氧化碳CO 2和水H 20，此时，目标物质可以为二氧化碳，或者，滤芯可以对含氯挥发性有机物进行分解，得到二氧化碳CO 2、水H 20以及其他物质，此时，目标物质也可以为二氧化碳。
如图1所示，该滤芯寿命监测方法包括以下步骤：
步骤101，在采用滤芯进行空气净化过程中，监测目标物质的浓度。
本公开实施例中，在用户开启空气净化设备后，可以采用滤芯对空气进行净化，此时，滤芯可以对污染物质进行分解，得到目标物质。在空气净化过程中，可以采用相关传感器，检测目标物质的浓度。
例如，当目标物质为二氧化碳时，可以利用二氧化碳传感器检测目标物质的浓度。
步骤102，根据监测到的目标物质的浓度，确定滤芯寿命。
可以理解的是，在预设时间段内，若目标物质的浓度上升明显，则表明滤芯分解的污染物质较多，空气净化设备的净化能力较强，此时，可以确定滤芯寿命非寿命末期，而若目标物质的浓度未发生明显变化，或者未发生变化，则表明滤芯分解的污染物质较少，或者，滤芯并未分解污染物质，此时，可以确定滤芯寿命为寿命末期。
因此，本公开实施例中，可以根据监测到的目标物质的浓度，确定滤芯寿命。例如，可以根据预设时间段内，目标物质的浓度变化量，确定滤芯寿命，或者，可以根据单位时间内的目标物质的浓度变化量，确定滤芯寿命，对此不作限制。由此，可以准确识别滤芯寿命，从而可以避免未正确识别滤芯寿命而导致的相关问题，例如可以避免寿命末期的滤芯仍然服役而导致净化性能下降的情况，或者可以避免未到寿命末期的滤芯被替换而造成资源浪费的情况。
需要说明的是，虽然可以采用相关传感器，直接检测污染物质的浓度，根据污染物质的浓度确定芯片寿命，例如，当污染物质为甲醛时，可以通过甲醛传感器检测甲醛浓度，若预设时间段内，甲醛浓度下降明显，此时，可以确定空气净化设备的净化效果较好，进而确定滤芯寿命非寿命末期。但是，甲醛传感器的寿命较短，若将甲醛传感器设置在空气净化设备中，需要频繁更换甲醛传感器，例如半年或者一年对甲醛传感器进行更换，成本较高。
而本公开实施例中，根据对污染物质进行分解得到的目标物质的浓度，确定芯片的寿命，例如，当目标物质为二氧化碳时，二氧化碳传感器的寿命较长，因此，无需对其进行频繁更换，可以降低成本。并且，通过相关传感器检测目标物质的浓度，根据目标物质的浓度，确定滤芯寿命，还可以避免引用额外的不成熟技术而导致的风险等情况。
本公开实施例的滤芯寿命监测方法，通过在采用滤芯进行空气净化过程中，监测目标物质的浓度，并根据监测到的目标物质的浓度，确定滤芯寿命，其中，目标物质为滤芯对污染物质进行分解得到的。本公开中，根据目标物质的浓度，可以确定滤芯的净化能力和净化效果，进而根据净化能力或净化效果，可以确定滤芯寿命，由此，可以准确识别滤芯寿命，从而可以避免未正确识别滤芯寿命而导致的相关问题，例如可以避免寿命末期的滤芯仍然服役而导致净化性能下降的情况，或者可以避免未到寿命末期的滤芯被替换而造成资源浪费的情况。
作为一种可能的实现方式，可以获取空气净化设备在空气净化过程开始前的目标物质的浓度，以及获取空气净化过程开始后的预设时间段目标物质的浓度，通过根据两个时间点监测到的目标物质的浓度差值，确定滤芯寿命。下面结合图2，对上述过程进行详细说明。
图2为本公开实施例二所提供的滤芯寿命检测方法的流程示意图。
如图2所示，在图1所示实施例的基础上，步骤102具体可以包括以下子步骤：
步骤201，获取空气净化过程开始前目标物质的浓度。
本公开实施例中，空气净化过程开始前，指滤芯并未对空气进行净化，即滤芯对空气进行净化前。可以通过相关传感器，检测空气净化过程开始前目标物质的浓度。
例如，可以在空气净化设备开启后，用户并未触发净化功能时，通过相关传感器，检测目标物质的浓度。具体地，当用户通过触摸空气净化设备的虚拟按键或者实体按键，启动空气净化设备后，或者，当用户通过移动终端上控制电器设备的应用程序(Application，简称APP)，启动空气净化设备后，并且，用户并未触发净化功能时，此时，空气净化设备处于空气净化过程开始前，可以通过相关传感器，检测目标物质的浓度，例如标记空气净化过程开始前目标物质的浓度为C1。
其中，移动终端可以为手机、平板电脑、个人数字助理、穿戴式设备、车载设备等具有各种操作系统、触摸屏和/或显示屏的硬件设备。
步骤202，计算浓度差值，浓度差值是空气净化过程开始后的预设时间段目标物质的浓度与空气净化过程开始前目标物质的浓度之间的浓度差值。
本公开实施例中，预设时间段为预先设置的，例如可以为空气净化设备的内置程序预先设置的，或者还可以由用户进行设置，对此不作限制，比如预设时间段可以为30min、1h等等。空气净化过程开始后的预设时间段，是指空气净化设备开启后，滤芯对空气进行净化后的预设时间段，比如滤芯对空气进行净化后的30min。
本公开实施例中，在空气净化过程开始后的预设时间段，例如空气净化设备开启后，滤芯对空气进行净化后的30min，可以通过相关传感器采集目标物质的浓度，例如标记空气净化过程开始后的预设时间段目标物质的浓度为C2，将C2与C1作差，得到空气净化过程开始后的预设时间段目标物质的浓度与空气净化过程开始前目标物质的浓度之间的浓度差值为|C2-C1|。由此，在空气净化过程开始后,可以实现将相关传感器实时采集的目标物质的浓度，与空气净化过程开始前目标物质的浓度进行比较，来确定滤芯的寿命，可以提升后续步骤中滤芯寿命确定的准确性。
步骤203，根据浓度差值，确定滤芯寿命。
可以理解的是，当滤芯寿命非寿命末期时，其净化性能较好，随着时间的增长，分解得到的目标物质越来越多，空气净化设备所在空间中的目标物质的浓度也越来越高。因此，作为本公开实施例的一种可能的实现方式，可以判断浓度差值|C2-C1|是否低于第一阈值，若是，则确定滤芯寿命为寿命末期，若否，则确定滤芯寿命非寿命末期。其中，第一阈值为预先设置的，例如可以为空气净化设备的内置程序预先设置的，或者，还可以由用户进行设置，对此不作限制。
需要说明的是，当空气净化设备所在空间不同时，由于空间大小差异、环境温度、湿度差异等外在因素，可能导致滤芯在同等净化效率下，测量得到的目标物质的浓度存在显著的变化，例如，空间A的体积小于空间B，假设滤芯在空间A分解的得到的目标物质，与滤芯在空间B中分解得到的目标物质一样多，由于空间A的体积小于空间B，则空间A中的目标物质的浓度大于空间B中的目标物质的浓度，因此，根据浓度差值|C2-C1|是否低于第一阈值，来判断滤芯寿命，可能影响判断结果的准确性。
因此，作为本公开实施例的另一种可能的实现方式，可以根据浓度差值|C2-C1|计算增长系数，根据增长系数，确定滤芯寿命。具体地，可以将浓度差值|C2-C1|与空气净化过程开始前目标物质的浓度C1做比值，得到增长系数。由于随着滤芯的不断使用，净化能力逐渐减弱，增长系数是不断减小的，因此，可以判断增长系数是否低于第三阈值，若是，则表明滤芯的净化能力较弱，此时，可以确定滤芯寿命为寿命末期，若否，则确定滤芯寿命非寿命末期。其中，第三阈值为预先设置的，例如可以为空气净化设备的内置程序预先设置的，或者，还可以由用户进行设置，对此不作限制。
作为本公开实施例的又一种可能的实现方式，还可以根据增长系数以及预设的参考增长系数，确定滤芯寿命。
作为一种可能的实现方式，可以计算增长系数和参考增长系数的第一衰减幅度，例如，标记增长系数为S1，参考增长系数为S2，第一衰减幅度为D1，则S1＝|C2-C1|/C1，D1＝|S1-S2|/S2，而后，可以判断第一衰减幅度D1是否高于第四阈值，若是，则表明滤芯的净化效果衰减明显，净化能力较弱，此时，可以确定滤芯寿命为寿命末期，若否，则确定滤芯寿命非寿命末期。
作为另一种可能的实现方式，还可以判断增长系数S1和参考增长系数S2之间的差值|S2-S1|是否低于第五阈值，若是，则表明滤芯的净化能力较弱，此时，可以确定滤芯寿命为寿命末期，若否，则确定滤芯寿命非寿命末期。
其中，第四阈值和第五阈值为预先设置的，例如可以为空气净化设备的内置程序预先设置的，或者，还可以由用户进行设置，对此不作限制。
举例而言，以污染物质为甲醛，目标物质为CO 2示例，假设空气净化设备启动后，室内的CO 2浓度为400ppm，10分钟后，室内的CO 2浓度为420ppm，则增长系数S1＝|420-400|/400＝0.05，假设参考增长系数S2＝0.125，第四阈值为50％，则D1＝|0.05-0.125|/0.125＝60％>50％，因此，可以确定滤芯除醛效果衰减明显，滤芯寿命为寿命末期。
需要说明的是，上述仅以参考增长系数为预先设置的进行示例，实际应用时，考虑到当参考增长系数为空气净化设备的内置程序预先设置时，其值与出厂前的标定环境相关， 如空间大小差异、环境温度、湿度差异等，可能造成不同空间对应的参考增长系数存在较大的差异，从而影响滤芯寿命判断结果的准确性，因此，本公开中，可以获取首次使用滤芯时监测到的目标物质的浓度，并确定首次使用滤芯时单位时间内的浓度差值，根据单位时间内的浓度差值确定参考增长系数。具体地，可以将首次使用滤芯时单位时间内的浓度差值与首次使用滤芯时监测到的目标物质的浓度做比值，得到参考增长系数。
进一步地，在滤芯寿命为寿命末期时，可以对用户进行提示，以提醒用户更换滤芯，例如可以通过空气净化设备进行语音播报，或者，可以通过移动终端上的控制电器设备的APP向用户发送提示信息，对此不作限制。而当滤芯寿命非寿命末期时，可以继续监测目标物质的浓度，以对滤芯寿命进行实时监测，即返回重新执行步骤202及后续步骤。
本公开实施例的滤芯寿命监测方法，可以通过根据滤芯的净化效果或净化能力，确定滤芯寿命，可以提升滤芯寿命确定结果的准确性。
作为一种可能的实现方式，还可以根据单位时间内的目标物质的浓度变化量，确定滤芯寿命。下面结合图3，对上述过程进行详细说明。
图3为本公开实施例三所提供的滤芯寿命监测方法的流程示意图。
如图3所示，在图1所示实施例的基础上，步骤102具体可以包括以下子步骤：
步骤301，根据监测到的目标物质的浓度，确定单位时间内的浓度变化量。
本公开实施例中，单位时间为预先设置的，例如可以为1min、10min等等。浓度变化量可以为浓度的绝对变化量，或者，也可以为浓度的相对变化量，对此不作限制。例如，标记浓度变化量为T0，标记前一时刻检测得到的目标物质的浓度为C3，当前时刻检测到的目标物质的浓度为C4，则浓度的绝对变化量为T0＝|C4-C3|,浓度的相对变化量为T0＝|C4-C3|/C3。
步骤302，根据浓度变化量，确定滤芯寿命。
可以理解的是，当滤芯寿命非寿命末期时，其净化性能较好，随着时间的增长，分解得到的目标物质越来越多，空气净化设备所在空间中的目标物质的浓度也越来越高。因此，当单位时间内的浓度变化量较高时，可以确定滤芯寿命非寿命末期，而当单位时间内的浓度变化量较低时，可以确定滤芯寿命为寿命末期。
作为一种可能的实现方式，可以判断浓度变化量是否低于第六阈值，若是，则表明滤芯的净化能力较弱，此时，可以确定滤芯寿命为寿命末期，若否，则确定滤芯寿命非寿命末期。其中，第六阈值为预先设置的，例如可以为空气净化设备的内置程序预先设置的，或者，还可以由用户进行设置，对此不作限制。
本公开实施例的滤芯寿命监测方法，通过根据单位时间内的浓度变化量，确定滤芯寿命，同样可以提升确定结果的准确性。
作为另一种可能的实现方式，还可以设定一个参考浓度变化量，并计算浓度变化量与参考浓度变化量间的浓度变化量差值，根据浓度变化量差值，确定滤芯寿命。下面结合图4，对上述过程进行详细说明。
图4为本公开实施例四所提供的滤芯寿命监测方法的流程示意图。
如图4所示，在图3所示实施例的基础上，步骤302具体可以包括以下子步骤：
步骤401，对浓度变化量，计算与设置的参考浓度变化量之间的浓度变化量差值。
作为本公开实施例的一种可能的实现方式，参考浓度变化量可以为预先设置的，例如标记为T1，则单位时间内的浓度变化量T0与参考浓度变化量T1之间的浓度变化量差值为|T1-T0|。
需要说明的是，上述仅以参考浓度变化量为预先设置的进行示例，实际应用时，考虑到当参考浓度变化量为空气净化设备的内置程序预先设置时，其值与出厂前的标定环境相关，如空间大小差异、环境温度湿度差异等，可能造成不同空间对应的参考浓度变化量存在较大的差异，从而影响滤芯寿命判断结果的准确性。因此，作为本公开实施例的另一种可能的实现方式，可以获取首次使用滤芯时监测到的浓度C0，并确定首次使用滤芯时单位时间内的浓度变化量，而后，根据首次使用滤芯时单位时间内的浓度变化量，设置参考浓度变化量T1。
步骤402，根据浓度变化量差值，确定滤芯寿命。
可以理解的是，当滤芯寿命非寿命末期时，其净化性能较好，随着时间的增长，分解得到的目标物质越来越多，空气净化设备所在空间中的目标物质的浓度也越来越高。因此，作为本公开实施例的一种可能的实现方式，可以判断浓度变化量差值|T1-T0|是否低于第二阈值，若是，则确定滤芯寿命为寿命末期，若否，则确定滤芯寿命非寿命末期。其中，第二阈值为预先设置的，例如可以为空气净化设备的内置程序预先设置的，或者，还可以由用户进行设置，对此不作限制。
需要说明的是，当空气净化设备所在空间不同时，由于空间大小差异、环境温度湿度差异等外在因素，可以导致滤芯在同等净化效率下，测量得到的目标物质的浓度存在显著的变化，例如，空间A的体积小于空间B，假设滤芯在空间A分解的得到的目标物质，与滤芯在空间B中分解得到的目标物质，由于空间A的体积小于空间B，则空间A中的目标物质的浓度大于空间B中的目标物质的浓度，因此，根据浓度变化量差值|T1-T0|是否低于第二阈值，来判断滤芯寿命，可能影响判断结果的准确性。
因此，作为本公开实施例的另一种可能的实现方式，还可以根据单位时间内的浓度变化量T0，计算实时增长系数，根据实时增长系数，确定滤芯寿命。具体地，标记实时增长系数U1，则U1＝T0/C3＝|C4-C3|/C3，由于随着滤芯的不断使用，净化能力逐渐减弱，增长 系数是不断减小的，因此，可以判断实时增长系数U1是否低于第七阈值，若是，则表明滤芯的净化能力较弱，此时，可以确定滤芯寿命为寿命末期，若否，则确定滤芯寿命非寿命末期。
其中，第七阈值为预先设置的，例如，可以为空气净化设备的内置程序预先设置的，或者，还可以由用户进行设置，对此不作限制。
作为本公开实施例的又一种可能的实现方式，还可以根据实时增长系数以及参考浓度增长系数，确定滤芯寿命。其中，参考浓度增长系数可以为预先设置的，也可以根据参考浓度变化量T1确定，比如标记参考浓度增长系数为U2，则U2＝T1/C0。
作为一种可能的实现方式，可以判断实时增长系数U1和参考浓度增长系数U2之间的差值|U2-U1|是否低于第八阈值，若是，则表明滤芯的净化能力较弱，此时，可以确定滤芯寿命为寿命末期，若否，则确定滤芯寿命非寿命末期。
作为另一种可能的实现方式，还可以计算实时增长系数U1和参考浓度增长系数U2之间的第二衰减幅度，例如标记第二衰减幅度为D2，则D2＝|U2-U1|/U2，而后，可以判断第二衰减幅度是否高于第九阈值，若是，则表明滤芯的净化效果衰减明显，净化能力较弱，此时，可以确定滤芯寿命为寿命末期，若否，则确定滤芯寿命非寿命末期。
其中，第八阈值和第九阈值为预先设置的，例如可以为空气净化设备的内置程序预先设置的，或者，还可以由用户进行设置，对此不作限制。
举例而言，假设第九阈值为50％，首次使用滤芯时监测到的浓度C0为400ppm，在单位时间ΔT后获取到的浓度为450ppm，则参考浓度增长系数U2＝(450-400)/400＝0.125，当前时刻检测到的目标物质的浓度C4为420ppm，前一时刻检测得到的目标物质的浓度C3为400ppm，则实时增长系数U1＝(420-400)/400＝0.05，第二衰减幅度D2＝|0.05-0.125|/0.125＝60％>50％，因此，可以确定滤芯除醛效果衰减明显，滤芯寿命为寿命末期，此时，可以提醒用户更换滤芯，以避免寿命末期的滤芯仍然服役而导致净化性能下降的情况，改善用户的使用体验。
需要说明的是，上述第一阈值、第二阈值、…、第八阈值、第九阈值的取值可以相同，也可以不同，对此不作限制。
为了实现上述实施例，本公开还提出一种滤芯寿命监测装置。
图5为本公开实施例五所提供的滤芯寿命监测装置的结构示意图。
本公开实施例中，滤芯用于对污染物质进行分解得到目标物质。
如图5所示，该滤芯寿命监测装置包括：监测模块101和确定模块102。
其中，监测模块101，用于在采用滤芯进行空气净化过程中，监测目标物质的浓度。
作为一种可能的实现方式，滤芯可为除甲醛滤芯，此时，目标物质可为二氧化碳。
确定模块102，用于根据监测到的目标物质的浓度，确定滤芯寿命。
作为第一种可能的实现方式，确定模块102，具体用于：获取空气净化过程开始前目标物质的浓度；计算浓度差值，浓度差值是空气净化过程开始后的预设时间段目标物质的浓度与空气净化过程开始前目标物质的浓度之间的浓度差值；根据浓度差值，确定滤芯寿命。
作为第二种可能的实现方式，确定模块102，具体用于：若浓度差值低于第一阈值，确定滤芯寿命为寿命末期。
作为第三种可能的实现方式，确定模块102，具体用于：根据监测到的目标物质的浓度，确定单位时间内的浓度变化量；根据浓度变化量，确定滤芯寿命。
作为第四种可能的实现方式，确定模块102，具体用于：对浓度变化量，计算与设置的参考浓度变化量之间的浓度变化量差值；根据浓度变化量差值，确定滤芯寿命。
作为第五种可能的实现方式，确定模块102，具体用于：若浓度变化量差值低于第二阈值，确定滤芯寿命为寿命末期。
作为第六种可能的实现方式，确定模块102，还用于：根据首次使用滤芯时监测到的浓度，确定首次使用滤芯时单位时间内的浓度变化量；根据首次使用滤芯时单位时间内的浓度变化量，设置参考浓度变化量。
