背景技术Background technique
随着空气污染越来越严重，雾霾天气越来越多，越来越多的人不喜欢开窗。为了避免空调长时间运行后，室内空气中的氧气含量不能满足人体需求。相关技术中出现了富氧空调，富氧空调可以将室外空气中的氧气输送至室内，以改善室内的空气状况。As air pollution becomes more and more serious, and more and more haze weather, more and more people do not like opening windows. In order to avoid the long-term operation of the air conditioner, the oxygen content in the indoor air cannot meet the needs of the human body. Oxygen-enriched air conditioners have appeared in related technologies, and oxygen-enriched air conditioners can transport oxygen from outdoor air to indoors to improve indoor air conditions.
当前的富氧空调一般是通过氧气传感器检测室内空气中的氧气含量以控制制氧模块的开启。而在空气中存在少量污染物，氧气浓度变化不大时，需要氧气传感器具备非常高的检测精度，才能检测出室内空气中的氧气变化，而高精度的氧气传感器通常价格昂贵且寿命短，这导致富氧空调的成本较高。The current oxygen-enriched air conditioner generally detects the oxygen content in the indoor air through an oxygen sensor to control the opening of the oxygen generation module. When there are a small amount of pollutants in the air and the oxygen concentration does not change much, the oxygen sensor needs to have a very high detection accuracy to detect the oxygen change in the indoor air. High-precision oxygen sensors are usually expensive and have a short life. As a result, the cost of oxygen-enriched air conditioners is higher.

图7示出了根据本发明一实施例的用于富氧空调100的控制方法的流程示意图。如图7所示，本发明由上述实施例的控制器执行的用于富氧空调的控制方法可以至少包括如下步骤：Fig. 7 shows a schematic flowchart of a control method for an oxygen-enriched air conditioner 100 according to an embodiment of the present invention. As shown in FIG. 7, the control method for the oxygen-enriched air conditioner executed by the controller of the above embodiment of the present invention may at least include the following steps:
S102：获取活动状态检测装置检测到的室内人员的活动状态。S102: Acquire the activity state of the indoor personnel detected by the activity state detection device.
S104：获取VOC检测模块检测到的室内空气中的VOC浓度。S104: Acquire the VOC concentration in the indoor air detected by the VOC detection module.
S106：根据VOC浓度和室内人员的活动状态控制制氧模块按照对应的预设运行模式运行。S106: Control the oxygen generation module to operate according to the corresponding preset operating mode according to the VOC concentration and the activity state of indoor personnel.
在本发明实施例中，处理器162通过VOC检测模块直接检测室内空气中的VOC浓度进而控制制氧模块的运行模式，降低了富氧空调的成本。另外，处理器162在获取到室内人员的活动状态及VOC浓度后，会根据VOC浓度和活动状态控制制氧模块按照对应的预设运行模式运行，从而可以快速降低室内的VOC浓度，使室内空气的含氧量快速达到最优含氧量，提高了 用户的体验。In the embodiment of the present invention, the processor 162 directly detects the VOC concentration in the indoor air through the VOC detection module to control the operation mode of the oxygen generation module, thereby reducing the cost of the oxygen-enriched air conditioner. In addition, after the processor 162 obtains the activity status and VOC concentration of the indoor personnel, it will control the oxygen generation module to operate according to the corresponding preset operating mode according to the VOC concentration and activity status, so that the indoor VOC concentration can be quickly reduced and the indoor air The oxygen content quickly reaches the optimal oxygen content, which improves the user experience.
在本发明的一些实施例中，参见图1-4，对于活动状态检测装置是摄像头140的情况，处理器162会配置成获取摄像头140采集到的室内的当前图像并对当前图像进行识别、获取室内人员的姿态信息，从而确定室内人员的活动状态，活动状态包括睡眠状态和非睡眠状态。In some embodiments of the present invention, referring to FIGS. 1-4, for the case where the active state detection device is the camera 140, the processor 162 is configured to obtain the current indoor image collected by the camera 140 and to recognize and obtain the current image. The posture information of the indoor personnel is used to determine the activity state of the indoor personnel. The activity state includes the sleeping state and the non-sleeping state.
在确定活动状态之后，处理器162会判断室内人员是否均处于睡眠状态，若室内人员均处于睡眠状态，处理器162会判断VOC浓度是否达到预设VOC浓度阈值，若VOC浓度达到预设VOC浓度阈值，则控制制氧模块170释放预设氧气浓度的氧气。After determining the active state, the processor 162 will determine whether all the indoor personnel are in a sleep state. If the indoor personnel are all in a sleep state, the processor 162 will determine whether the VOC concentration reaches the preset VOC concentration threshold, and if the VOC concentration reaches the preset VOC concentration Threshold, the oxygen generation module 170 is controlled to release oxygen with a preset oxygen concentration.
其中，预设VOC浓度阈值对应的是一个很大的值，例如10.0mg/m 3，VOC浓度超过预设VOC浓度阈值表明室内的空气质量很差，此时为了降低室内的VOC浓度，处理器162会控制制氧模块170开启并释放预设氧气浓度的氧气，预设氧气浓度是一个很小的值，例如20％氧气浓度，这样不仅可以降低室内VOC浓度也可以尽量避免制氧模块170工作时产生的噪音影响到用户休息。 Among them, the preset VOC concentration threshold corresponds to a very large value, such as 10.0mg/m 3. The VOC concentration exceeding the preset VOC concentration threshold indicates that the indoor air quality is poor. At this time, in order to reduce the indoor VOC concentration, the processor 162 will control the oxygen generation module 170 to turn on and release oxygen with a preset oxygen concentration. The preset oxygen concentration is a very small value, such as 20% oxygen concentration. This can not only reduce the indoor VOC concentration but also avoid the oxygen generation module 170 from working as much as possible. The noise generated at the time affects the rest of the user.
在本发明的一些实施例中，若室内存在人员处于非睡眠状态，处理器162则会根据预设的VOC浓度和氧气浓度关系映射表，确定室内的VOC浓度对应的氧气浓度。In some embodiments of the present invention, if there is a person in a non-sleep state indoors, the processor 162 will determine the oxygen concentration corresponding to the indoor VOC concentration according to a preset VOC concentration and oxygen concentration relationship mapping table.
表1VOC浓度和氧气浓度关系映射表Table 1 Mapping table of the relationship between VOC concentration and oxygen concentration
VOC浓度(mg/m 3) VOC concentration (mg/m 3 ) 氧气浓度Oxygen concentration
0.3-1.00.3-1.0 00
1.0-3.01.0-3.0 40％40%
3.0-10.03.0-10.0 60％60%
>10.0>10.0 90％90%
具体地，参见表1，VOC浓度介于0.3mg/m 3-1.0mg/m 3时，表示室内的空气质量较好，无需开启制氧模块170，对应的氧气浓度为0；VOC浓度介于1.0mg/m 3-3.0mg/m 3时，表示室内的空气质量一般，对应的制氧模块170所要释放的氧气的氧气浓度为40％；VOC浓度介于3.0mg/m 3-10.0mg/m 3时，表示室内的空气质量较差，对应的制氧模块170所要释放的氧气的氧气浓度为60％；VOC浓度>10.0mg/m 3时，表示室内的空气质量很差，对应的制氧模块170所要释放的氧气的氧气浓度为90％。 Specifically, Table 1, VOC concentration of between 0.3mg / m 3 -1.0mg 3 when / m, indicates better indoor air quality, without opening the oxygen module 170, corresponding to an oxygen concentration of 0; VOC concentration of between When 1.0mg/m 3 -3.0mg/m 3 , it means that the indoor air quality is normal. The oxygen concentration of the oxygen released by the corresponding oxygen generating module 170 is 40%; the VOC concentration is between 3.0mg/m 3 -10.0mg/ m 3 , it means that the indoor air quality is poor, and the oxygen concentration of the oxygen to be released by the corresponding oxygen generation module 170 is 60%; when the VOC concentration>10.0mg/m 3 , it means the indoor air quality is very poor, and the corresponding system The oxygen concentration of the oxygen to be released by the oxygen module 170 is 90%.
其中，VOC浓度越大，对应的氧气浓度越大，从而开启制氧模块170后可以快速降低室内的VOC浓度。Among them, the greater the VOC concentration, the greater the corresponding oxygen concentration, so that the indoor VOC concentration can be quickly reduced after the oxygen generation module 170 is turned on.
在根据表1确定VOC浓度对应的氧气浓度后，在本发明的一些实施例中，处理器162会对当前图像识别以获取人脸信息，从而确定室内的当前人数和各个人的年龄估值。其中，人脸信息可以包括人脸轮廓、人脸特征点、多种几何比例数据(如两眼之间的间距)等诸多数据。通过对人脸信息分析可以确定室内的当前人数和各个人的年龄估值。After determining the oxygen concentration corresponding to the VOC concentration according to Table 1, in some embodiments of the present invention, the processor 162 recognizes the current image to obtain face information, thereby determining the current number of people indoors and the age estimate of each person. Among them, the face information may include a lot of data such as face contour, face feature points, various geometric ratio data (such as the distance between two eyes). By analyzing the face information, the current number of people in the room and the age estimate of each person can be determined.
之后，处理器162会判断年龄估值中是否存在超过预设年龄阈值的年龄估值，其中，预设年龄阈值可以是60、70、80等，具体可以依据实际情况设定，本发明对此不做具体的限定。若年龄估值中存在超过预设年龄阈值的年龄估值，处理器162则会在根据表1确定出的氧气浓度的基础上增加预设百分比的氧气浓度作为第一目标氧气浓度，之后开启制氧模块170使其释放第一目标氧气浓度的氧气。其中预设百分比可以是20％，具体可以依据实际情况设定。After that, the processor 162 will determine whether there is an age estimate that exceeds a preset age threshold in the age estimate. The preset age threshold can be 60, 70, 80, etc., which can be set according to actual conditions. Do not make specific restrictions. If there is an age estimate that exceeds the preset age threshold in the age estimate, the processor 162 will increase the oxygen concentration by a preset percentage on the basis of the oxygen concentration determined according to Table 1 as the first target oxygen concentration, and then turn on the control system. The oxygen module 170 causes it to release oxygen at the first target oxygen concentration. The preset percentage can be 20%, which can be set according to actual conditions.
举例来说，预设年龄阈值是70、预设百分比为20％。若根据表1确定VOC浓度对应的氧气浓度为0且室内存在超过70岁的人，则开启制氧模块170并使其释放氧气浓度为20％的氧气；若根据表1确定VOC浓度对应的氧气浓度为40％且室内存在超过70岁的人，则开启制氧模块170并使其释放氧气浓度为60％的氧气；若根据表1确定VOC浓度对应的氧气浓度为90％且室内存在超过70岁的人，则开启制氧模块170并使其释放100％氧气浓度的氧气。在根据VOC浓度对应氧气浓度为90％的情况下，由于最高的氧气浓度为100％，因此控制制氧模块170释放氧气浓度为100％的氧气。For example, the preset age threshold is 70 and the preset percentage is 20%. If it is determined according to Table 1 that the oxygen concentration corresponding to the VOC concentration is 0 and there are people over 70 years old in the room, turn on the oxygen generation module 170 and make it release oxygen with an oxygen concentration of 20%; if the oxygen corresponding to the VOC concentration is determined according to Table 1 If the concentration is 40% and there are people over 70 years old in the room, turn on the oxygen generating module 170 and make it release oxygen with an oxygen concentration of 60%; if it is determined according to Table 1 that the oxygen concentration corresponding to the VOC concentration is 90% and the indoor presence exceeds 70 For a person who is 10 years old, turn on the oxygen generating module 170 and make it release 100% oxygen concentration oxygen. When the oxygen concentration corresponding to the VOC concentration is 90%, since the highest oxygen concentration is 100%, the oxygen generation module 170 is controlled to release oxygen with an oxygen concentration of 100%.
在室内存在人员处于非睡眠状态的情况下，本发明综合VOC浓度和室内人员的年龄来控制制氧模块170所要释放的氧气的氧气浓度，从而可以快速降低室内的VOC浓度，使室内空气的含氧量快速达到最优含氧量。When there are people in a non-sleeping state indoors, the present invention integrates the VOC concentration and the age of the indoor personnel to control the oxygen concentration of the oxygen to be released by the oxygen generating module 170, so that the indoor VOC concentration can be quickly reduced, and the indoor air content The oxygen content quickly reaches the optimal oxygen content.
处理器162在判断年龄估值中是否存在超过预设年龄阈值的年龄估值之后，在本发明的一些实施例中，处理器还162还可以判断室内的当前人数是否超过预设人数阈值。其中，预设人数阈值可以是一人，也可以是多人，本发明对此不限定。若处理器162判断室内的当前人数超过预设人数阈值，处理器162则会在第一目标氧气浓度的基础上增加预设百分比的氧气浓度作为第二目标氧气浓度，使制氧模块170释放第二目标氧气浓度的氧气。After the processor 162 determines whether there is an age estimate that exceeds the preset age threshold in the age estimate, in some embodiments of the present invention, the processor 162 may also determine whether the current number of people in the room exceeds the preset threshold. Wherein, the preset threshold for the number of people may be one person or multiple people, which is not limited in the present invention. If the processor 162 determines that the current number of people in the room exceeds the preset number threshold, the processor 162 will increase the oxygen concentration by a preset percentage on the basis of the first target oxygen concentration as the second target oxygen concentration, so that the oxygen generation module 170 releases the second target oxygen concentration. 2. The oxygen of the target oxygen concentration.
举例来说，预设年龄阈值是70、预设人数阈值为1、预设百分比为20％。若根据表1确定VOC浓度对应的氧气浓度为0且室内多于1人存在，且存在超过70岁的人，则使制氧模块170释放氧气浓度为40％的氧气；若根据表1确定VOC浓度对应的氧气浓度为40％且室内多于1人存在，且存在超过70岁的人，则使制氧模块170并释放氧气浓度为80％的氧气；若根据表1确定VOC浓度对应的氧气浓度为90％且室内多于1人存在，且存在超过70岁的人，则使制氧模块170释放氧气浓度为100％的氧气。其中，在根据根据表1确定VOC浓度对应的氧气浓度为90％的情况下，由于最高的氧气浓度为100％，因此控制制氧模块170释放氧气浓度为100％的氧气。For example, the preset age threshold is 70, the preset number of people threshold is 1, and the preset percentage is 20%. If it is determined according to Table 1 that the oxygen concentration corresponding to the VOC concentration is 0 and there is more than one person in the room, and there are people over 70 years old, the oxygen generating module 170 will release oxygen with an oxygen concentration of 40%; if the VOC is determined according to Table 1 The oxygen concentration corresponding to the concentration is 40% and there is more than one person in the room, and there are people over 70 years old, then the oxygen generating module 170 will release oxygen with an oxygen concentration of 80%; if the oxygen corresponding to the VOC concentration is determined according to Table 1 If the concentration is 90% and there is more than one person in the room, and there are people over 70 years old, the oxygen generating module 170 will release oxygen with an oxygen concentration of 100%. Wherein, when the oxygen concentration corresponding to the VOC concentration is determined to be 90% according to Table 1, since the highest oxygen concentration is 100%, the oxygen generation module 170 is controlled to release oxygen with an oxygen concentration of 100%.
在室内存在人员处于非睡眠状态的情况下，本发明进一步综合VOC浓度和室内人员的年龄和室内的当前人数来控制制氧模块170所要释放的氧气的氧气浓度，从而可以快速降低室内的VOC浓度使室内空气含氧量快速达到最优含氧量。When there are people in a non-sleeping state in the room, the present invention further integrates the VOC concentration and the age of the indoor people and the current number of people in the room to control the oxygen concentration of the oxygen to be released by the oxygen generating module 170, so as to quickly reduce the indoor VOC concentration Make the indoor air oxygen content quickly reach the optimal oxygen content.
在本发明的一些实施例中，参见图1-2、5-6，对于活动状态检测装置是红外检测装置150的情况，处理器162可以配置成通过红外检测装置150检测室内人员在设定时长内动作是否发生变化从而获取室内人员的活动状态。具体地，若检测到室内人员在预设时长内动作未变化，室内人员则处于睡眠状态；若检测到室内人员在预设时长内动作发生变化，室内人员则处于非睡眠状态。In some embodiments of the present invention, referring to FIGS. 1-2 and 5-6, for the case where the activity state detection device is the infrared detection device 150, the processor 162 may be configured to detect that the person in the room is in the set time period through the infrared detection device 150 Whether the internal movement changes so as to obtain the activity status of the indoor personnel. Specifically, if it is detected that the movement of the indoor person has not changed within the preset time period, the indoor person is in a sleep state; if it is detected that the movement of the indoor person has changed within the preset time period, the indoor person is in a non-sleep state.
之后，处理器162会判断室内人员是否均处于睡眠状态，若室内人员均处于睡眠状态，则判断VOC浓度是否达到预设VOC浓度阈值，若VOC浓度达到预设VOC浓度阈值，处理器162则控制制氧模块170开启并释放预设氧气浓度的氧气。After that, the processor 162 will determine whether all the people in the room are in a sleep state. If all the people in the room are in a sleep state, it will determine whether the VOC concentration has reached the preset VOC concentration threshold. If the VOC concentration has reached the preset VOC concentration threshold, the processor 162 will control The oxygen generation module 170 is turned on and releases oxygen with a preset oxygen concentration.
其中，预设VOC浓度阈值对应的是一个很大的值，例如10.0mg/m 3，VOC浓度超过预设VOC浓度阈值表明室内的空气质量很差，此时为了降低室内的VOC浓度，处理器162会控制制氧模块170开启并释放预设氧气浓度的氧气，预设氧气浓度是一个很小的值，例如20％氧气浓度，这样不仅可以降低室内VOC浓度也可以尽量避免制氧模块170工作时产生的噪音影响到用户休息。 Among them, the preset VOC concentration threshold corresponds to a very large value, such as 10.0mg/m 3. The VOC concentration exceeding the preset VOC concentration threshold indicates that the indoor air quality is poor. At this time, in order to reduce the indoor VOC concentration, the processor 162 will control the oxygen generation module 170 to turn on and release oxygen with a preset oxygen concentration. The preset oxygen concentration is a very small value, such as 20% oxygen concentration. This can not only reduce the indoor VOC concentration but also avoid the oxygen generation module 170 from working as much as possible. The noise generated at the time affects the rest of the user.
而若处理器162根据活动状态判断室内存在人员处于非睡眠状态，处理器162则会在根据表1确定VOC浓度对应的氧气浓度之后，获取红外检测 装置150检测到的室内的当前人数，判断当前人数是否超过预设人数阈值，若当前人数超过预设人数阈值，处理器162会在根据表1确定出的氧气浓度的基础上增加预设百分比的氧气浓度作为第一目标氧气浓度，开启制氧模块使其释放第一目标氧气浓度的氧气。If the processor 162 determines that there are people in the room that are not sleeping according to the activity state, the processor 162 will obtain the current number of people in the room detected by the infrared detection device 150 after determining the oxygen concentration corresponding to the VOC concentration according to Table 1, and determine the current number of people in the room. Whether the number of people exceeds the preset number threshold, if the current number of people exceeds the preset number threshold, the processor 162 will increase the oxygen concentration by a preset percentage based on the oxygen concentration determined according to Table 1 as the first target oxygen concentration, and turn on the oxygen production The module causes it to release oxygen at the first target oxygen concentration.
举例来说，预设人数阈值为1、预设百分比为20％。若根据表1确定VOC浓度对应的氧气浓度为0且室内多于1人存在，则开启制氧模块170并使其释放氧气浓度为20％的氧气；若根据表1确定VOC浓度对应的氧气浓度为40％且室内多于1人存在，则开启制氧模块170并使其释放氧气浓度为60％的氧气；若根据表1确定VOC浓度对应的氧气浓度为90％且室内多于1人存在，则开启制氧模块170并使其释放氧气浓度为100％的氧气。在根据表1确定VOC浓度对应的氧气浓度为90％的情况下，由于最高的氧气浓度为100％，因此控制制氧模块170释放氧气浓度为100％的氧气。For example, the preset threshold for the number of people is 1, and the preset percentage is 20%. If it is determined according to Table 1 that the oxygen concentration corresponding to the VOC concentration is 0 and there is more than one person in the room, turn on the oxygen generation module 170 and make it release oxygen with an oxygen concentration of 20%; if the oxygen concentration corresponding to the VOC concentration is determined according to Table 1 If it is 40% and there is more than one person in the room, turn on the oxygen generation module 170 and make it release oxygen with an oxygen concentration of 60%; if it is determined according to Table 1 that the oxygen concentration corresponding to the VOC concentration is 90% and there is more than one person in the room , The oxygen generating module 170 is turned on and it releases oxygen with an oxygen concentration of 100%. When it is determined according to Table 1 that the oxygen concentration corresponding to the VOC concentration is 90%, since the highest oxygen concentration is 100%, the oxygen generation module 170 is controlled to release oxygen with an oxygen concentration of 100%.
在室内机设置红外检测装置150且室内存在人员处于非睡眠状态的情况下，本发明综合VOC浓度和室内的当前人数来控制制氧模块170释放的氧气的氧气浓度，从而可以快速降低室内的VOC浓度，使室内空气的含氧量快速达到最优含氧量。When the infrared detection device 150 is installed in the indoor unit and there are people in a non-sleeping state in the room, the present invention integrates the VOC concentration and the current number of people in the room to control the oxygen concentration of the oxygen released by the oxygen generating module 170, so as to quickly reduce the indoor VOC Concentration, so that the oxygen content of the indoor air quickly reaches the optimal oxygen content.
在制氧模块170开启后，在本发明的一些实施例中，处理器162还可以配置成在第一预设时长内周期性获取VOC检测模块130检测到的室内的VOC浓度并通过智能设备发送室内的当前VOC浓度和空气质量状况。第一预设时长可以为1h，也可以为多小时，本发明对此不做具体限定。智能设备可以包括智能音箱、智能手机、个人数字助理等。若包括智能音箱，则可以通过智能音箱播报当前的VOC浓度以及空气气质量状况；若包括智能手机，则可以通过智能手机上的APP显示当前的VOC浓度以及气质量情况，这便于用户可以更好的感知室内的VOC浓度变化。若在第一预设时长内检测到VOC浓度下降到预设阈值则关闭制氧模块，并通过智能设备发送室内的当前的VOC浓度和空气质量状况，从而可以精确控制室内空气的含氧量并使用户及时获取室内的空气状况。After the oxygen generation module 170 is turned on, in some embodiments of the present invention, the processor 162 may also be configured to periodically obtain the indoor VOC concentration detected by the VOC detection module 130 within a first preset time period and send it through the smart device. The current indoor VOC concentration and air quality status. The first preset duration may be 1 hour or multiple hours, which is not specifically limited in the present invention. Smart devices may include smart speakers, smart phones, personal digital assistants, and so on. If it includes smart speakers, the current VOC concentration and air quality can be reported through the smart speakers; if it includes a smart phone, the current VOC concentration and air quality can be displayed through the APP on the smart phone, which is convenient for users to better Sense of indoor VOC concentration changes. If it is detected that the VOC concentration drops to the preset threshold within the first preset time period, the oxygen generation module will be turned off, and the current indoor VOC concentration and air quality status will be sent through the smart device, so that the oxygen content of the indoor air can be accurately controlled and Allow users to obtain the indoor air condition in time.
而若在第一预设时长后，室内的VOC浓度仍高于预设阈值，则说明可能是制氧模块出现了故障，此时关闭制氧模块并通过智能设备发送室内的当前VOC浓度及空气质量状况，从而提醒用户。If after the first preset time period, the indoor VOC concentration is still higher than the preset threshold, it means that the oxygen generation module may be faulty. At this time, the oxygen generation module is turned off and the current indoor VOC concentration and air are sent through the smart device. Quality status, thereby reminding users.
在本发明一些实施例中，在制氧模块开启后，若在第二预设时长内始终 获取不到VOC检测模块检测到的VOC浓度，第二预设时长小于第一预设时长。则说明可能是VOC检测模块出现了故障，处理器162则在制氧模块的开启时长达到第一预设时长后关闭制氧模块170并向智能设备发送故障报警提醒，从而不仅可以有效降低室内的VOC浓度还可以使用户及时了解故障情况。In some embodiments of the present invention, after the oxygen generation module is turned on, if the VOC concentration detected by the VOC detection module is not always obtained within the second preset time period, the second preset time period is less than the first preset time period. It means that the VOC detection module may be faulty, and the processor 162 will turn off the oxygen generation module 170 after the oxygen generation module has been turned on for the first preset period of time and send a failure alarm reminder to the smart device, which can not only effectively reduce the indoor The VOC concentration can also enable users to understand the fault situation in time.
另外，在本发明的一些实施例中，处理器162还可以配置成接收由智能设备发送的关于制氧模块170的开启时长的指令，并在达到开启时长后，通过智能设备发送室内当前的VOC浓度和空气质量状况。In addition, in some embodiments of the present invention, the processor 162 may also be configured to receive an instruction on the opening duration of the oxygen generating module 170 sent by the smart device, and after the opening duration is reached, send the current indoor VOC through the smart device. Concentration and air quality status.

At this time, in order to reduce the indoor VOC concentration, the processor 162 will control the oxygen generation module 170 to turn on and release oxygen with the preset oxygen concentration. The preset oxygen concentration is a very small value, such as 20% oxygen concentration, which can not only reduce the indoor VOC concentration, but also try to avoid the noise generated by the oxygen generation module 170 from affecting the user's rest.
S25：返回步骤S21。S25: Return to step S21.
S26：根据预设的VOC浓度和氧气浓度关系映射表确定VOC浓度对应的氧气浓度并获取红外检测装置检测到的室内的当前人数。S26: Determine the oxygen concentration corresponding to the VOC concentration according to the preset mapping table of the relationship between the VOC concentration and the oxygen concentration, and obtain the current number of people in the room detected by the infrared detection device.
S27：判断室内的当前人数是否超过预设人数阈值，若否，执行步骤28；若是，执行步骤S29。S27: Determine whether the current number of people in the room exceeds the preset number threshold, if not, go to step 28; if yes, go to step S29.
S28：若当前人数未超过预设人数阈值，控制制氧模块释放所述氧气浓度的氧气并在VOC浓度降低到预设阈值时关闭制氧模块，返回步骤S21，从而快速降低室内的VOC浓度。S28: If the current number of people does not exceed the preset threshold, control the oxygen generation module to release the oxygen with the oxygen concentration and turn off the oxygen generation module when the VOC concentration drops to the preset threshold, and return to step S21 to quickly reduce the indoor VOC concentration.
S29：若当前人数超过预设人数阈值，在所述氧气浓度的基础上增加预设百分比的氧气浓度作为第一目标氧气浓度并控制制氧模块释放第一目标氧气浓度的氧气，在VOC浓度降低到预设阈值时关闭制氧模块，返回步骤S21，从而快速降低室内的VOC浓度。S29: If the current number of people exceeds the preset number threshold, add a preset percentage of oxygen concentration based on the oxygen concentration as the first target oxygen concentration and control the oxygen generation module to release oxygen at the first target oxygen concentration, and the VOC concentration is reduced When the preset threshold is reached, the oxygen generation module is turned off, and step S21 is returned to quickly reduce the indoor VOC concentration.
