[0024] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.

[0025] This application discloses a method for analyzing the surrounding environment. Figure 1 The surrounding environment analysis method disclosed in this application comprises the following steps: S101, obtaining an air cleanliness value within a coverage area or obtaining an air cleanliness value of a sensor within the coverage area; S102, determining a cruise route according to the air cleanliness value and performing mobile purification within the coverage area according to the cruise route; S103, acquiring image data in the surrounding environment during mobile purification and extracting feature objects in the image data, wherein the feature objects include human objects and non-human objects; S104, judging the behavior of the feature object and determining a purification strategy according to the behavior of the feature object.

[0026] First of all, it needs to be explained that the surrounding environment analysis method disclosed in the present application is based on a movable air sensor. The movable air sensor is mainly composed of four parts: a mobile chassis, an air purifier, a sensor and a controller. The air purifier is installed on the mobile chassis, and the sensor and the controller are installed on the mobile chassis or the air purifier.

[0027] In step S101, the air purifier first obtains the air cleanliness value within the coverage area or obtains the air cleanliness value of the sensor within the coverage area, see Figure 2 The way to obtain the air cleanliness value within the coverage area is to cruise within the coverage area and rely on the sensors carried by the user to obtain data. Please refer to Figure 3 ,The way of acquiring the air cleanliness value of the sensor existing within the ,coverage range is to communicate with the sensor and obtain the air cleanliness value detected by the sensor.

[0028] In step S102, a cruise route is determined according to the air cleanliness value and mobile purification is performed within the coverage area according to the cruise route. Figure 4 As shown by the dotted line in , the method of determining the cruise route according to the air cleanliness value here is to first determine the areas that need to be purified according to the air cleanliness value, and then connect these areas in sequence to obtain the cruise route.

[0029] The corresponding scenario here is that there are no feature objects in the coverage area. In step S103, the air purifier obtains image data of the surrounding environment during the mobile purification process and extracts feature objects in the image data. The feature objects are divided into two categories, namely human objects and non-human objects.

[0030] When there is a characteristic object in the surrounding environment, step S104 is executed, in which the behavior of the characteristic object is judged and a purification strategy is determined according to the behavior of the characteristic object. That is, when the characteristic object appears, the environment in which the characteristic object is located is processed first.

[0031] The specific method of obtaining the air cleanliness value within the coverage area and determining the cruise route according to the air cleanliness value is: S201, dividing the coverage area into regions to obtain multiple independent purification regions; S202, setting at least one first data collection point in each independent purification area; S203, generating a cruise route according to the first data collection points, where each first data collection point is located on the cruise route.

[0032] When the surrounding environment of the first data collection point changes, the first data collection point whose surrounding environment remains unchanged is removed on the cruise route. At this time, the change in the surrounding environment of the first data collection point refers to the appearance of a feature object in the surrounding environment. At this time, the first data collection point whose surrounding environment remains unchanged will be removed on the cruise route. That is, as recorded in the previous article, when a feature object appears, the environment in which the feature object is located will be processed first.

[0033] When the air cleanliness values ​​at the first data collection points on the cruise route are all within the normal range, all the first data collection points of the independent purification area will be re-incorporated into the cruise route.

[0034] In some examples, the specific way to determine the behavior of a feature object is: S301, setting a second data collection point according to the location of the feature object, the number of the second data collection point is at least one; S302, obtaining the behavior of the feature object at each second data collection point, where the behavior includes influencing behavior and non-influencing behavior.

[0035] See also Figure 5 In step 301 and step S302, a second data collection point is set according to the location of the feature object, because the location of the feature object may conflict with the first data collection point at this time, and then the behavior of the feature object at each second data collection point is obtained at the second data collection point, and the behavior includes influencing behavior and non-influencing behavior.

[0036] It should be noted here that the second data collection point will change according to the location of the feature object, that is, when the location of the feature object changes, the second data collection point will also move accordingly.

[0037] When the behavior of the characteristic object includes an influencing behavior, a continuous purification strategy is configured for the location where the influencing behavior is located until the influencing behavior disappears and the air cleanliness value at the location where the influencing behavior is located returns to normal; When the behaviors of the characteristic object include only non-influencing behaviors, an intermittent purification strategy is configured for the location of the non-influencing behaviors.

[0038] The way to determine influencing behavior and non-influencing behavior refers to whether the behavior has a direct impact on the surrounding environment, such as smoking and pets' toileting behavior, etc., and of course it can also be user-defined behavior.

[0039] Of course, when executing the purification strategy, it is also necessary to continuously or intermittently obtain image data at the second data collection point. When an influencing behavior appears in the image data, the intermittent purification strategy at the second data collection point corresponding to the influencing behavior is replaced with a continuous purification strategy.

[0040] The present application also provides a surrounding environment analysis device, comprising: A data acquisition unit, used to acquire the air cleanliness value within the coverage area or acquire the air cleanliness value of the sensor within the coverage area; A purification processing unit is used to determine a cruise route according to the air cleanliness value and to perform mobile purification within the coverage area according to the cruise route; A continuous detection unit, used to obtain image data in the surrounding environment and extract characteristic objects in the image data during the mobile purification process, wherein the characteristic objects include human objects and non-human objects; The strategy allocation unit is used to judge the behavior of the feature object and determine the purification strategy according to the behavior of the feature object.

[0041] Further, obtaining the air cleanliness value within the coverage area and determining the cruise route according to the air cleanliness value includes: Divide the coverage area into multiple independent purification areas; At least one first data collection point is set in each independent purification area; A cruise route is generated according to the first data collection points, and each first data collection point is located on the cruise route.

[0042] Further, when the surrounding environment of the first data collection point changes, the first data collection point whose surrounding environment remains unchanged is removed on the cruise route; The change in the surrounding environment of the first data collection point includes the appearance of a feature object at the first data collection point.

[0043] Furthermore, when the air cleanliness values ​​at the first data collection points on the cruise route are all within a normal range, all the first data collection points of the independent purification area are incorporated into the cruise route.

[0044] Furthermore, the behavior of determining the feature object includes: Setting a second data collection point according to the location of the feature object, wherein the number of the second data collection point is at least one; The behavior of the feature object at each second data collection point is obtained, where the behavior includes influencing behavior and non-influencing behavior.

[0045] Furthermore, it also includes: When the behavior of the characteristic object includes an influencing behavior, a continuous purification strategy is configured for the location where the influencing behavior is located until the influencing behavior disappears and the air cleanliness value at the location where the influencing behavior is located returns to normal; When the behaviors of the characteristic object include only non-influencing behaviors, an intermittent purification strategy is configured for the location of the non-influencing behaviors.

[0046] Furthermore, when executing the purification strategy, image data at the second data collection point is continuously or intermittently acquired, and when an influencing behavior appears in the image data, the intermittent purification strategy at the second data collection point corresponding to the influencing behavior is replaced with a continuous purification strategy.
