All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Referring to fig. 1, fig. 1 is a flowchart of a motor overheat protection method for air purification in the present application.

s3: and acquiring motor data corresponding to the pollution sources according to the overheat protection type, configuring overheat protection data according to the motor data, and controlling the motor to work according to the overheat protection data.
It should be noted that, the environmental data may include image data and gas data, and may be directly obtained by using a conventional monitoring device such as a camera, a gas sensor, and the like. The position information is used for analyzing the relative distance between the pollution source and the air purifier, and the infection information is used for analyzing the severity of the pollution source infecting the atmosphere. And analyzing the working states of motors of the air purifier, which are used for coping with various pollution sources, according to the position distance and the infection degree of the pollution sources so as to generate the current overheat factor. And judging the overheat protection type by comparing the current overheat factor with a preset overheat factor, namely, judging which motor in the air purifier has the risk of overload working phenomenon. The overheat protection data after the motor is reconfigured and down-regulated is used for improving the use safety of the high-risk motor type, meanwhile, the normal use of other motors can not be influenced, and the overheat protection performance of the motor for air purification is improved and meanwhile, the use effect of a user can be guaranteed.
According to the embodiment of the application, the environmental data includes gas data and image data, and the acquiring of the environmental data of the air purifying space is specifically:
acquiring gas data of the air purification space through a gas detection device, and acquiring image data of the air purification space through an image acquisition device;
the gas detection equipment is arranged in an external pollution area and an internal key pollution area of the air purification space, and the image acquisition equipment is arranged in an internal common pollution area of the air purification space.
It should be noted that, the external contamination area refers to an indoor area directly contacting with the external atmosphere, for example, an area adjacent to the window, and the contamination source is generally from the external atmosphere, and the gas detection apparatus may be disposed at the window. An interior heavy pollution area refers to an indoor area in direct contact with an indoor heavy pollution source, such as a kitchen area, where the pollution source may come from kitchen cooking, and where a gas detection device may be disposed at a kitchen doorway. The internal common pollution area refers to an indoor area which is in indirect contact with the external atmosphere or an indoor heavy pollution source and is in direct contact with an indoor conventional pollution source, such as a living room and a bedroom, the pollution source can come from the indoor pollution source, and because of the difference problem between indoor layout and pollution source distribution, image data needs to be adopted for analysis, and at the moment, an image acquisition device can be arranged at the center or each corner of the room.
According to the embodiment of the application, the environmental data is image data, and the analysis of the position information and the infection information of the pollution source in the air purification space according to the environmental data specifically includes:
identifying a characteristic region with a pollution source identifier in the image data and working coordinates with an air purifier identifier;
calculating a barycentric point coordinate according to the distribution condition of the characteristic region, and calculating a linear distance between a working coordinate and the barycentric point coordinate to generate the position information;
and calculating the invasion area according to the area of the characteristic area, and calculating the ratio of the invasion area to the image data area to generate the invasion information.
It should be noted that, because in the working process of the air purifier, the difference of the relative positions among the air purifier, the pollution source and the user is considered, the purifying effect and the overheat protection performance of the air purifier are further enhanced, and whether the running states of the motors generate larger effects or not needs to be known, for example, the situation that the pollution source is closer to the air purifier, but the user is farther from the pollution source is likely to exist, and at the moment, the air purifier has lower effects on the user although adopting higher energy consumption to cope with the pollution source, so that the overheat protection threshold value of the air purifier can be properly reduced to improve the use safety, and meanwhile, the requirement of the user on the air purification is not influenced. The characteristic region and the working coordinates refer to the region and the coordinates of the pollution source and the air purifier in the image data respectively. The location information and the infestation information of the contamination source can be analyzed by identifying the characteristic areas or working coordinates with the identification in the image data using conventional image processing techniques. The center of gravity point coordinates can be generated by taking the center point of each pollution source as a basic origin, taking every three adjacent basic origins as a reference system, and then taking the center of gravity points of each reference system in the image data as a reference system. The infection information can be obtained by firstly obtaining the plane area of the characteristic region by adopting a conventional image processing technology, and then dividing the obtained image data total plane area to generate the plane area ratio of the characteristic region, namely the infection information.
According to the embodiment of the application, the identification of the characteristic area with the pollution source mark in the image data is specifically:
identifying a profile of the pollution source in a pollution form;
and acquiring image data according to a preset interval time, marking the outline in the image data as the pollution source identifier, and marking the occupied area of the outline as the characteristic area.
The contamination source in the image data may be germs released from household garbage, pollen of plants, hair of animals, etc., and the outline of the contamination source in the contamination form may be, for example, the outline of the overflow shape of a garbage can, the outline of the open shape of plant petals, the outline of the movable shape of animals, etc. The profile may be entered by the user himself or derived from a large database. The image data is acquired according to the preset interval time, the current environment change can be analyzed in real time, so that different overheat protection measures can be taken, wherein the preset interval time can be set to be 30 minutes.
According to the embodiment of the application, the environmental data is gas data, and the analysis of the position information and the infection information of the pollution source in the air purification space according to the environmental data is specifically as follows:
acquiring a linear distance of the gas detection device monitoring the gas data relative to the air purifier as the position information;
and acquiring the ratio of the gas data to the preset gas concentration as the infection information.
It should be noted that, in the gas data, the pollution source may be commonly found in kitchen fume and external harmful gas, and the indirect pollution may not need to monitor the position of the pollution source, but the distance between the pollution source and the air purifier needs to be analyzed to determine the working efficiency of the air purifier.
According to the embodiment of the application, the current overheat factor is generated according to the position information and the infection information of the pollution source and compared with the preset overheat factor specifically comprises the following steps:
generating a single overheat factor corresponding to a single pollution source according to the position information and the infection information of the single pollution source;
acquiring a single preset overheat factor of the air purifier for the pollution source;
and comparing the single overheat factor with the single preset overheat factor, and marking the pollution source with the single overheat factor exceeding the single preset overheat factor.
If the environmental data is image data, assuming that the area of the overflow garbage can shot by the intelligent camera accounts for one half of the whole shot picture, setting the distance between the characteristic area and the working area to be 2m, and setting the overheat factor to be 10; then, assuming that the blossom degree of flowers shot by the intelligent camera is the full bloom period, setting the overheat factor to be 4, and setting the overheat factor to be larger along with the fact that the position is closer and the infection degree is higher. If the environmental data is gas data, the gas sensor is assumed to sense that the concentration of cooking fume reaches the preset gas concentration of 30mg/m 3 The distance between the feature area and the working area is 2m, and the overheating factor is set to be 5. The single pollution sources may include harmful gases from external pollution areas, oil smoke gases from internal major pollution areas, and germs, pollen, hair, etc. from internal general pollution areas. Single item of coping with single item pollution sourceThe preset overheat factor is an initial overheat factor calculated according to initial overheat protection data such as the safe output power of the purification equipment motor with the single pollution source, and can be set to be 1-5. Because the positions of the pollution sources and the infection degree sensed by the sensors are different, the working power of each working assembly in the air purifier is inconsistent relative to the respective initial overheat protection data, and therefore the working assemblies with larger current loads can be screened by comparing the single overheat factor with the single preset overheat factor.
According to an embodiment of the present application, further comprising:
acquiring human body data of the air purification space, and judging whether the human body data meets a preset distance condition;
and if the preset distance condition is met, adjusting the preset overheat factor according to the human body data, and comparing the current overheat factor with the adjusted preset overheat factor again.
It should be noted that, the human body data is used to determine whether the user is located in the air purifying space and the position thereof, and may be obtained by using image data or using an infrared sensor. The human body data satisfying the preset distance condition indicates that the user is not within the air purifying range or is far away from the air purifier, for example, may be set to be greater than 5m. The preset overheat factor can be adjusted downwards to reduce the load of the air purifier in time so as to reduce the threshold value for starting overheat protection of the motor.
According to the embodiment of the application, the motor data corresponding to the pollution source is obtained according to the overheat protection type specifically as follows:
if the single overheat factor exceeds the pollution source of the single preset overheat factor, acquiring motor data of the sterilizing equipment and the dust removing equipment;
and if the single overheat factor exceeds the pollution source of the single preset overheat factor, acquiring the motor data of the fume removing equipment and the harmful gas removing equipment.
It should be noted that if the pollution source corresponding to the single overheat factor exceeding the single preset overheat factor comes from the image data, the overheat protection type is judged to be a biological pollution source purifying mode, and the related system corresponding to the pollution source comprises a sterilizing device and a dust removing device. If the single overheat factor exceeds the pollution source corresponding to the single preset overheat factor and comes from the gas data, judging that the overheat protection type is a chemical pollution source purifying mode, and the related system corresponding to the pollution source comprises a fume removing device and a harmful gas removing device. The motor data may be a current value, a voltage value, or a power value of the motor of the relevant system device. The overheat protection data can be configured according to the motor data by directly adjusting the overheat protection data of the corresponding motor down to be lower than the initial overheat protection data, that is, setting the maximum output power of the overheat protection data to be lower than the safe output power, for example, when the system gives an alarm after overheat protection type exists, the overheat protection data=motor operation current value (initial overheat factor/current overheat factor) =0.5×4/7=0.29 < 0.5 is configured, and overheat protection of the high risk motor is achieved. The overheat protection data can be configured according to the motor data, namely, the current overheat level is judged according to the comparison condition of the current overheat factor and the preset overheat factor, the maximum output power of the current overheat level is regulated down in proportion according to the overheat level, the overheat factor of the current degerming equipment and the preset overheat factor are respectively 10 and 2, the overheat factor and the preset overheat factor are divided to obtain a weight value of 5, the current overheat level is judged to be over heat, the overheat protection data=motor working current value is configured, and the overheat level coefficient=0.5x1/2=0.25; then, assuming that the overheat factor of the current oil smoke removing device and the preset overheat factor are respectively 5 and 2, dividing the two to obtain a weight value of 2.5, judging the current overheat level to be middle overheat, and configuring overheat protection data=motor working current value×overheat level coefficient=0.5×3/5=0.3.
