Description

Technical Field

[0001] The present application relates to the field of smart home technology, and in particular to an air purification method and an air purifier based on environmental perception. Background Art

[0002] The working principle of an air purifier is to use a fan to draw air through multiple filters, filtering out solid particles in the air, and producing clean air that is almost free of solid particles. If the air passing through is subjected to ultraviolet radiation of sufficient intensity during the solid particle filtering process, sterile clean air can be obtained.

[0003] Air purifiers can be divided into two categories, whole-house air purifiers and single-unit air purifiers. Whole-house air purifiers are similar to fresh air systems and can purify the air entering the house. Single-unit air purifiers are placed directly in the house to purify the air in a certain area.

[0004] The advantage of a whole-house air purifier is its wide coverage, but it can only perform primary filtration and cannot quickly treat a single polluted area; the advantage of a single-unit air purifier is its higher filtration accuracy, but due to its individual size and power, its coverage will be limited.

[0005] Therefore, most families tend to choose single air purifiers. For families with large indoor areas and many family members, they need to configure multiple single air purifiers. Although this solves the air quality problem to a certain extent, it also brings problems such as increased noise, increased maintenance and the need to move, causing certain inconveniences.

[0057] The technical solution in this application is further described in detail below with reference to the accompanying drawings.

[0058] This application discloses an air purification method based on environmental perception, please refer to Figure 1 The air purification method based on environmental perception disclosed in this application includes the following steps:

[0059] S101, obtaining air index values ​​within a coverage area or air index values ​​generated by a sensor within the coverage area;

[0060] S102, determining a purification area based on air index values;

[0061] S103, obtaining objects existing in the environment within the coverage area, including tracked objects and non-tracked objects;

[0062] S104, when there is a tracking object in the environment within the coverage area, analyzing the movement trajectory of the tracking object and purifying the coverage area according to the analysis result;

[0063] S105 , when there are only non-tracked objects in the environment within the coverage area, purify the coverage area according to the air index value within the coverage area or the air index value generated by the sensor within the coverage area.

[0064] Overall, the air purification method based on environmental perception provided in this application needs to be implemented based on a movable air purifier. The movable air purifier mainly consists of a mobile chassis, a purifier housing, a purifier filter element, a sensor and a controller. The purifier housing is installed on the mobile chassis, the purifier filter element is located inside the purifier housing, the sensor and controller are deployed on the purifier housing, and a fan is also installed on the purifier housing to provide power for air flow.

[0065] The execution subject of this application is the controller in the air purifier. For ease of understanding and unified description, the execution subject will be collectively referred to as the air purifier in the following text.

[0066] In step S101, the air purifier first obtains the air index value within the coverage area or the air index value generated by the sensor within the coverage area, see Figure 2 The way to obtain the air index value within the coverage area is that the air purifier cruises within the coverage area and obtains the air index value through its own sensor. Figure 2 The dotted line in the figure indicates the movement path of the air purifier when it is moving. Figure 3 ,Getting the air index value generated by the sensor within the coverage range means that the sensor feeds back the detected air index value to the air purifier. Figure 3 The circle in the figure represents the air purifier, and the rectangle represents the sensor.

[0067] In step S102, the purification area is determined based on the air index value. The purification area here refers to the area that needs to be processed. The specific determination method is based on the air index value. For example, the specified standard value is 50. When the obtained air index value is greater than 50, it means that the area needs to be purified. Otherwise, the area does not need to be purified.

[0068] In step S103 , objects existing in the environment within the coverage area are also obtained. Objects are divided into two categories: tracking objects and non-tracking objects. The environment within the coverage area here refers to the environment within the coverage area of ​​the purification area.

[0069] When there are no objects in the environment within the coverage area, the purification area is determined according to the air index value and each purification area is purified in sequence. The corresponding scenario here is that there are no living objects such as family members and pets in the house.

[0070] When there is a tracking object in the environment within the coverage area, step S104 is executed. In this step, the movement trajectory of the tracking object is analyzed and the coverage area is purified according to the analysis results. The corresponding scenario of this method is that there are family members inside the house, and the air purifier adopts a following strategy to purify the air.

[0071] When there are only non-tracked objects in the environment within the coverage area, step S105 is executed. In this step, the coverage area is purified according to the air index value within the coverage area or the air index value generated by the sensor within the coverage area. This method corresponds to the scenario where there are living things such as pets inside the house. The air purifier purifies each purification area in sequence.

[0072] In some examples, when obtaining the air index value within the coverage area, it also includes determining the type of area to which the air index value corresponds. The purpose of determining the type of area to which the air index value corresponds is that some areas do not need to be processed, such as kitchens and bathrooms. Of course, it also includes areas specially set by users, such as bedrooms. This part involves user-defined content and will not be repeated here.

[0073] The coverage area includes multiple areas. Generally speaking, the coverage area can be divided into bedrooms, dining rooms, living rooms, entertainment rooms, lounges and study rooms, etc.

[0074] In some examples, the specific method for determining the type of area corresponding to the air quality index value is:

[0075] S201, reaching the middle position of the area corresponding to the air index value;

[0076] S202, acquiring environmental content data of an environment within a coverage area at a middle position, where the environmental content data includes image data and / or point cloud data;

[0077] S203, extracting feature objects from the environmental content data;

[0078] S204: Determine the type of the area corresponding to the air index value according to the feature object.

[0079] In steps S201 to S204, the type of area is determined based on the environmental content data in the environment within the coverage area. The specific method is to first determine what objects exist in the environment within the coverage area, and then determine the type of area based on the objects. This judgment method requires the use of a trained judgment model for processing.

[0080] In some examples, the specific method of analyzing the movement trajectory of the tracked object and purifying the coverage area based on the analysis results is:

[0081] S301, when the tracking object moves, determining the target area of ​​the tracking object;

[0082] S302, obtaining an air index value of a target area or an air index value generated by a sensor in the target area;

[0083] S303: Determine whether the target area needs to be purified based on the air index value.

[0084] See also Figure 4 In step S301 to step S303, the target area of ​​the tracking object is first determined. The target area of ​​the tracking object refers to the area that the tracking object wants to reach, such as Figure 4As shown in the figure, the arrow indicates the moving direction of the tracked object, and the dotted line indicates the area that the tracked object wants to reach.

[0085] Then, the air index value of the target area or the air index value generated by the sensor in the target area is obtained. The acquisition method is described in the above content and will not be repeated here.

[0086] Finally, determine whether the target area needs to be purified based on the air index values.

[0087] When there are multiple target areas for the tracking object, obtain the air index values ​​of the target areas respectively or the air index values ​​generated by the sensors in the target areas;

[0088] Determine the target area to be purified according to the air index value, and the number of the target area to be purified can be zero, one, or more;

[0089] When there are multiple target areas to be purified, follow the movement of the tracking object and determine the target area of ​​the tracking object. If the target area of ​​the tracking object is not the target area to be purified, return to the original position. If the target area of ​​the tracking object is the target area to be purified, purify the target area to be purified.

[0090] When there are multiple tracking objects, use the following method to handle it:

[0091] S401, determining the number of target areas to be purified;

[0092] S402, when there are multiple target areas to be purified, obtaining the current air index value of each target area to be purified;

[0093] S403, configuring a purification plan based on the current air index values ​​of each target area to be purified;

[0094] S404: Perform purification processing on the plurality of target areas to be purified using a purification scheme.

[0095] In steps S401 to S404, the number of target areas to be purified is first determined. When the number of target areas to be purified is one, the target area to be purified is directly processed. When the number of target areas to be purified is multiple, the current air index value of each target area to be purified needs to be obtained, and then the purification plan is configured according to the current air index value of each target area to be purified.

[0096] The specific method of configuring the purification plan based on the current air index value of each target area to be purified is as follows:

[0097] Determine the priority of the tracking objects corresponding to the target area to be purified;

[0098] Configure a purification plan for the target area to be purified based on the priority of the tracked object. The purification plan includes continuous purification and intermittent purification.

[0099] When there are multiple tracking objects in a target area to be cleaned, the tracking object with the highest priority is selected as the tracking object corresponding to the target area to be cleaned.

[0100] The priority of the tracking object refers to the classification of the tracking object. Generally, children and the elderly are placed at the priority level, and others are placed at the general level, or the user can customize the settings. The purification scheme includes continuous purification processing and intermittent purification processing. The priority uses continuous purification processing, such as Figure 5 As shown, the general level uses intermittent purification treatment, such as Figure 6 As shown, the air purifier moves back and forth in three positions.

[0106] The second purification processing unit is used to purify the coverage area according to the air index value within the coverage area or the air index value generated by the sensor within the coverage area when only non-tracking objects exist in the environment within the coverage area.

[0107] Furthermore, when obtaining the air index value within the coverage area, it also includes determining the type of area corresponding to the air index value, and the coverage area includes multiple areas.

[0108] Furthermore, determining the type of area corresponding to the air index value includes:

[0109] Arrive at the middle position of the area corresponding to the air index value;

[0110] Acquire environmental content data of an environment within the coverage area at an intermediate position, the environmental content data including image data and / or point cloud data;

[0111] Extracting feature objects from environmental content data;

[0112] Determine the type of area corresponding to the air index value based on the feature object.

[0113] In a possible implementation of the first aspect, analyzing the movement trajectory of the tracked object and purifying the coverage area according to the analysis result includes:

[0114] When the tracked object moves, determine the target area of ​​the tracked object;

[0115] Obtaining air index values ​​in a target area or air index values ​​generated by sensors in the target area;

[0116] Determine whether the target area needs purification based on the air index values.

[0117] Furthermore, when there are multiple target areas for the tracking object, the air index values ​​of the target areas or the air index values ​​generated by the sensors in the target areas are obtained respectively;

[0118] Determine the target area to be purified according to the air index value, and the number of the target area to be purified can be zero, one, or more;

[0119] When there are multiple target areas to be purified, follow the movement of the tracking object and determine the target area of ​​the tracking object. If the target area of ​​the tracking object is not the target area to be purified, return to the original position. If the target area of ​​the tracking object is the target area to be purified, purify the target area to be purified.
