[0034] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0035] According to an embodiment of the present application, a control method embodiment of an air purifier is provided. It should be noted that the steps shown in the flowchart of the drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0036] In this embodiment, a control method of an air purifier is provided, which can be used in an air purifier, Figure 1 is a flowchart of an air purifier control method according to an embodiment of the present application, as Figure 1 shown, the flow includes the following steps:

[0037] Step S101: Obtain the current running mode of the air purifier.

[0038] Specifically, the working mode of the air purifier includes a normal mode without pet guardian function and a guardian mode with pet guardian function. For example, when the pet air purifier does not identify the pet (pet smart collar), the working mode of the air purifier is the normal mode, and when the pet is identified, the working mode of the pet air purifier can be set to the guardian mode.

[0039] Step S102: When the current running mode of the air purifier is the guardian mode, obtain the position information of the pet, wherein the position information is obtained by using ultra-wideband indoor positioning technology according to the positioning tag carried on the pet.

[0040] Specifically, the indoor positioning of the air purifier mainly includes positioning of the intelligent pet air purifier body and different pets, and identification of the pet air purifier for different pets. In order to obtain higher positioning accuracy, an ultra wide band (UWB) indoor positioning technology can be used for indoor positioning. Based on the user's house type and area size, three suitable UWB positioning base stations are selected and reasonably deployed to the appropriate positions of the house. In order to obtain the position information of the pet air purifier and different pets, positioning tags are built in the pet air purifier and the pet smart collar, and different pet collars are worn by different pets. The three positioning base stations obtain the relative position information of different positioning tags, and transmit the relevant data to the data processing center through wireless transmission such as WIFI technology, and then feedback to the application software of the related positioning system. In this way, the specific position information of the pet air purifier and different pets in the indoor can be obtained in real time.

[0041] Step S103: obtaining a map, wherein the map is constructed by using the ultra wide band indoor positioning technology and the laser radar sensor carried in the air purifier.

[0042] Specifically, the map can also be called an indoor high-precision map, which is mainly constructed by UWB technology and laser radar sensors on the pet air purifier, and supports automatic updating of the indoor map to adapt to changes in home layout, and also supports detection of dynamic obstacles and path optimization, thereby realizing dynamic planning of the moving path of the air purifier.

[0043] Step S104: determining whether a preset guardian purification task triggering condition is reached according to the position information and the map.

[0044] Specifically, the guardian purification task includes a pet area purification task and a pet following purification task. Under the pet area purification task, the pet air purifier can move to different pet areas such as pet defecation area and pet play area for purification work; the pet following purification task can be divided into pet return following purification task and pet movement following purification task.

[0045] Step S105: when the guardian purification task triggering condition is reached, performing the guardian purification task.

[0046] The control method of the air purifier provided by the embodiment fuses the ultra-wideband indoor positioning technology and the laser radar sensor to construct a map, and realizes accurate position tracking by combining the positioning label on the pet, thereby improving the targeted purification capability of the air purifier for the pet activity space on the premise of protecting the privacy of the user. Meanwhile, the method can intelligently judge whether the preset guarding and purifying condition is met, so as to automatically execute the corresponding purifying task, thereby not only improving the air purification efficiency, but also enhancing the intelligent level of the air quality management in the human-pet cohabitation environment, and having good application prospect and market promotion value.

[0047] In the embodiment, a control method of an air purifier is provided, which can be used for an air purifier, Figure 2 is a flowchart of another control method of an air purifier according to an embodiment of the present application, as shown in the figure, the flowchart comprises the following steps: Figure 2

[0048] Step S201: Obtain the current running mode of the air purifier.

[0049] Step S202: When the current running mode of the air purifier is the guarding mode, obtain the position information of the pet, wherein the position information is obtained by using the ultra-wideband indoor positioning technology according to the positioning label carried on the pet.

[0050] Step S203: Obtain the map, wherein the map is constructed by using the ultra-wideband indoor positioning technology and the laser radar sensor carried in the air purifier.

[0051] Step S204: Judge whether the preset guarding and purifying task triggering condition is met according to the position information and the map.

[0052] In an optional implementation, the guarding and purifying task comprises a pet area purifying task and a pet following purifying task; judging whether the preset guarding and purifying task triggering condition is met according to the position information and the map comprises the following steps:

[0053] Step S2041: Judge whether the staying duration of the pet in the preset pet activity area reaches a preset first duration threshold according to the position information and the map, when the staying duration of the pet in the pet activity area reaches the first duration threshold, it is determined that the triggering condition of the pet area purifying task is met.

[0054] Step S2042: Judge whether the pet returns from the outdoor or the duration of the pet's intense exercise reaches a preset second duration threshold according to the position information, when the pet returns from the outdoor or the duration of the pet's intense exercise reaches the second duration threshold, it is determined that the triggering condition of the pet following purifying task is met.

[0055] ​Specifically, for pets that often need to go outdoors or specific pets, an additional GPS positioning function can be selected for the pet collar, and for pets that go outdoors, the pet's behavior of going out and coming home can be recognized, and the pet's outdoor trajectory information can be recorded.

[0056] Specifically, the pet's movement space trajectory can be generated according to the pet's position information within a period of time, and the pet's displacement speed can be calculated according to the pet's displacement time and trajectory length. When the preset speed threshold is reached, it can be determined that the pet is in a state of vigorous movement. In addition, the complexity of the pet's displacement trajectory can also be used for auxiliary judgment, such as the pet's frequent displacement direction changes or circle turning within a short period of time.

[0057] Step S205: When the guardian purification task triggering condition is reached, it is determined whether there are other guardian purification tasks in the execution process; when there are other guardian purification tasks in the execution process, step S206 is entered; otherwise, step S209 is entered.

[0058] Step S206: Obtain a preset priority sorting rule.

[0059] This is because, in the guardian mode, since the guardian purification task can be automatically triggered, there are multiple working tasks at the same time. In order to execute multiple working tasks in order, the multiple working tasks existing at the same time need to be sorted according to the priority sorting rule. Specifically, the working tasks are executed according to the priority, and the working tasks with the same priority are executed according to the order of the working task triggering time. For example, when the guardian purification task is triggered, if the pet air purifier is executing a normal purification task, the current normal purification task is interrupted, the guardian purification task is executed preferentially, and after the guardian purification task is completed, the interrupted normal purification task is continued. Step S207: According to the priority sorting rule, it is determined whether the priority of the guardian purification task is higher than that of the other guardian purification tasks in the execution process; when the priority of the guardian purification task is higher than that of the other guardian purification tasks in the execution process, step S209 is entered; otherwise, step S208 is entered.

[0060] Step S208: Continue to execute the other guardian purification task, and after the other guardian purification task is executed, step S209 is entered.

[0061] Step S209: Execute the guardian purification task.

[0062] In an optional implementation, performing the daemon purifying task comprises: when a trigger condition of the pet area purifying task is reached, controlling the air purifier to enter the pet activity area according to the map, performing a first purifying process on the pet activity area until a preset purifying effect is reached; when a trigger condition of the pet following purifying task is reached, controlling the air purifier to perform a second purifying process according to the movement path of the pet until the preset purifying effect is reached.

[0063] Specifically, performing the first purifying process on the pet activity area comprises: determining a purifying type of the first purifying process according to the pet activity area; obtaining a personalized feature of the pet, and determining a first purifying parameter of the purifying type according to the personalized feature, wherein the personalized feature comprises at least one of the following: a kind of the pet, an age of the pet, a health status of the pet, a gender of the pet, and a character of the pet; the first purifying parameter comprises at least one of the following: a purifying wind speed and a purifying duration; and performing the first purifying process on the pet activity area by using the first purifying parameter.

[0064] Specifically, controlling the air purifier to perform the second purifying process according to the movement path of the pet comprises: obtaining a personalized feature of the pet, and determining a second purifying parameter of the second purifying process according to the personalized feature; wherein the personalized feature comprises at least one of the following: a kind of the pet, an age of the pet, a health status of the pet, a gender of the pet, and a character of the pet; and the second purifying parameter comprises at least one of the following: a purifying wind speed, a following distance, a following speed, and a purifying duration.

[0065] For example, the pet area purification task is that the pet air purifier can automatically move to different pet areas such as pet defecation area and pet playing area to perform purification work. The automatic triggering condition is as follows: when it is detected that a pet moves to the pet defecation area and stays for a certain period of time, the area purification task of the pet defecation area will be automatically triggered. The pet air purifier will move to the vicinity of the pet defecation area to perform deodorization and disinfection and sterilization purification. After a certain period of time, the TVOC and other odor sensors are used to detect the odor indicators such as ammonia gas. If it is reduced to below the safety threshold, the current purification task will be automatically ended or the next purification task will be performed. If it is not reduced to below the safety threshold, the pet air purifier will continue to purify for the same period of time and perform odor detection until the odor is reduced to below the safety threshold. When it is detected that a certain number of pets move to the pet playing area and stay for a certain period of time, the area purification task of the pet playing area will be automatically triggered. The pet air purifier will move to the vicinity of the pet playing area to perform purification such as floating hair adsorption. After a certain period of time, it will be automatically detected whether the number of pets in the pet playing area is at a preset value. If it is lower than the preset value, the current purification task will be automatically ended or the next purification task will be performed. If it reaches the preset value, the same purification task will be continued until the task end condition is reached. In addition, the user can also actively control the pet air purifier to perform the pet area purification task including other pet areas.

[0066] The pet following purification task is a task in which the pet air purifier follows the movement track of a specific pet to perform the following purification work. The pet following purification task mainly includes a pet returning following purification task and a pet moving following purification task. For the pet returning following purification task, the automatic triggering condition is as follows: after recognizing the behavior of the pet after returning from the outdoors, the pet returning following purification task is automatically triggered, the moving path of the pet is subjected to purification work such as floating hair adsorption, odor deodorization, and disinfection and sterilization, and a pet following distance is set. When the distance between the pet air purifier and the pet is greater than the pet following distance, the pet air purifier performs high-speed gear purification and can maintain a relatively high moving speed. When the distance between the pet air purifier and the pet is less than the pet following distance, low wind volume gear purification is performed and a relatively low moving speed is maintained. While ensuring a certain purification effect, the pet air purifier avoids greater wind volume and noise stimulation of the pet, stays near the pet to perform the purification work, and after a certain period of time, detects the odor index such as ammonia gas through a TVOC odor sensor. If the odor index is reduced to below a safety threshold, the current purification task is automatically ended or the next purification task is performed. If the odor index is not reduced to below the safety threshold, the pet air purifier continues to perform the same purification task. For the pet moving following purification task, the automatic triggering condition is that the pet air purifier is triggered after recognizing that the pet moves quickly in the house for a certain period of time through the pet collar. The execution strategy of the pet moving following purification task is the same as that of the pet returning following purification task, and only the triggering condition is different. Similarly, the user can also actively control the pet air purifier to perform the pet following purification task on a specific pet.

[0067] In addition to the different pet objects for guarding and purifying tasks, the pet object should also have a corresponding pet personalized purification plan. For example, the pet species, breed, hair type, and activity range will be different, the pet's age, health status, and personality, gender will be different, the pet's hair shedding amount, shedding period, noise tolerance, and respiratory sensitivity will also be different, so the purification parameters of different purification tasks when facing different pet objects can be adjusted, such as purification task duration, purification wind speed gear, pet following distance, etc.; and different pet safety distances can also be set for different pets, when the pet air purifier is within the pet safety distance, the pet air purification will be adjusted to the corresponding wind speed gear to avoid discomfort to older or easily stressed pets. At the same time, users can further edit and optimize related purification parameters, and feedback the purification effect after the completion of the purification task, and the pet air purifier will automatically optimize the purification plan according to the feedback results to achieve the best purification experience and purification effect for each pet. In addition, the pet air purifier can also generate a pet gathering location heat map according to the daily activity trajectory of each pet, so that users can more accurately divide different pet areas; at the same time, it can also prompt the user to perform the corresponding purification task and increase the number of prompts in the spring and other pet allergy seasons, or the shedding period of different pets, to improve the indoor purification effect and improve the comfort of pet life.

[0068] Step S210: determining whether the pet enters a preset pet restricted area according to the position information of the pet and the map, wherein the pet restricted area is determined according to the activity authority of the pet.

[0069] Step S211: when the pet enters the pet restricted area, the guarding and purifying task is suspended, the air purifier enters the pet restricted area, and a preset guiding task is executed to guide the pet to leave the pet restricted area; after the pet leaves the pet restricted area, the guarding and purifying task is continued.

[0070] That is, when there is an alarm task, if the air purifier is executing a purification task, the current purification task is interrupted, the alarm task is executed preferentially, and after the alarm task is removed, the interrupted purification task is continued.

[0071] Specifically, after the indoor high-precision map is constructed, the user can create different regional division schemes for the high-precision house map constructed by the pet air purifier, mainly including user area division and pet area division. The user area can be divided into a living room, a dining room, a bedroom, a balcony, a kitchen, a toilet and the like. The area where the pet is prohibited to enter can be set as a pet prohibited area. The pet area can be divided into a resting area, a defecation area, a feeding area and a playing area, etc. Through the position information of the pet, such as the arrival time and the leaving time of the pet in a certain area, the daily behavior of the pet can be preliminarily determined. Usually, through long-time optimization learning, the recognition and determination of the different daily behaviors of each pet can be further improved, and then the pet air purifier is triggered to perform corresponding purification tasks or alarm tasks.

[0072] In an optional embodiment, after the guardian purification task is performed, the following steps are further included: determining whether the pet goes out according to the position information of the pet and the map; when the pet goes out, determining whether the pet has the permission to go out; when the pet does not have the permission to go out, sending a prompt message.

[0073] For example, different pets can be assigned with corresponding pet collars according to the information such as the name, the species, the breed, the age, the gender, the character, the health condition, the permission to go out and the user area access permission, etc.

[0074] That is, the guardian mode further includes an alarm task, which mainly includes a pet going-out alarm task and a pet prohibited area alarm task. For the pet going-out alarm task, the triggering condition is that the pet without the permission to go out leaves the house. At this time, the user will receive the pet going-out alarm reminder and real-time positioning information of the pet outdoors. Optionally, when the user approaches the pet, the pet collar can be controlled to emit sound and light to help the user quickly find the pet. For the pet prohibited area alarm task, the triggering condition is that the pet without the permission enters the user area, such as the bedroom, the unsealed balcony and the balcony, etc. At this time, the user will receive the pet prohibited area alarm reminder, and the pet air purifier will move to the vicinity of the corresponding user area, attract the pet to approach the pet air purifier by emitting specific sound and light or specific smell such as catmint, and then take the pet away from the prohibited user area.

[0075] In an optional embodiment, the control method of the air purifier further includes the following steps: obtaining the power information of the air purifier; determining whether the air purifier needs to be charged according to the power information; when the air purifier needs to be charged, suspending the execution of the guardian purification task and controlling the air purifier to charge; after the air purifier completes the charging, continuing to execute the guardian purification task.

[0076] That is, the pet air purifier sets the power threshold for charging and powering off in the air purifier. When the air purifier power is lower than the charging threshold, the air purifier automatically interrupts the current purification task and creates a charging task. When the power reaches the power-off threshold, the air purifier automatically ends the charging task and continues the last interrupted purification task. The priority of the charging task is lower than that of the alarm task and higher than that of the purification task.

[0077] The air purifier control method provided in the embodiment introduces a priority judgment and scheduling mechanism for guardian purification tasks, ensuring that the air purifier can dynamically adjust the task execution order according to the preset rules when multiple tasks run in parallel, effectively avoiding task conflicts and improving the coordination and execution efficiency of the system. At the same time, this mechanism can flexibly configure the priority of tasks according to different scenarios, enhancing the intelligent response ability and adaptability of the air purifier in complex human-pet cohabitation environments.

[0078] In the embodiment, a control method of an air purifier is provided, which can be used for an air purifier, Figure 3 is a flowchart of another air purifier control method according to an embodiment of the present application, Figure 4 is a working task schematic diagram according to an embodiment of the present application.

[0079] As Figure 3 shown, the control method of the air purifier includes the following steps:

[0080] Step S301: Obtain the current running mode of the air purifier. When the current running mode of the air purifier is the guardian mode, go to step S302; when the current running mode of the air purifier is the normal purification mode, go to step S306.

[0081] Step S302: When the current running mode of the air purifier is the guardian mode, obtain the position information of the pet, wherein the position information is obtained by using the ultra-wideband indoor positioning technology according to the positioning tag carried on the pet.

[0082] Step S303: Obtain the map, wherein the map is constructed by using the ultra-wideband indoor positioning technology and the laser radar sensor carried in the air purifier.

[0083] Step S304: Determine whether the preset guardian purification task triggering condition is reached according to the position information and the map.

[0084] Step S305: When the guardian purification task triggering condition is reached, execute the guardian purification task.

[0085] As Figure 4As shown, the working tasks of the air purifier are purification tasks and alarm tasks, wherein the purification tasks can be divided into normal purification tasks and guardian purification tasks. The normal purification tasks are invoked and executed by the user, while the guardian purification tasks are mainly triggered and executed automatically by the air purifier, and can also be actively invoked and executed by the user. The guardian purification tasks include pet area purification tasks and pet following purification tasks. Under the pet area purification tasks, the pet air purifier can move to different pet areas such as pet defecation areas and pet play areas to perform purification work. The pet following purification tasks can be divided into pet return following purification tasks and pet exercise following purification tasks, and the execution strategies of the two following purification tasks are the same, and only the triggering conditions are different. The former is triggered when the pet returns after going out is identified through the pet collar, and the latter is triggered when the pet is identified to exercise intensively within a certain time. In addition to the purification tasks, the working tasks of the pet air purifier also include alarm tasks, which can be divided into pet going-out alarm tasks and pet forbidden area alarm tasks. For the pet going-out alarm task, the triggering condition is that the pet without going-out permission leaves the house. For the pet forbidden area alarm task, the triggering condition is that the pet without permission enters the user area, such as the bedroom, the unsealed balcony, and the balcony.

[0086] Step S306: Obtain the user instruction.

[0087] Specifically, in the normal purification mode, the user can manually execute and invoke the normal purification tasks of the air purifier through touch screen operation, mobile phone APP operation, voice operation and the like.

[0088] Step S307: Determine the purification range of the air purifier according to the user instruction.

[0089] As shown, Figure 4 The normal purification tasks include user area purification tasks and patrol purification tasks. Under the user area purification tasks, the pet air purifier can purify in the current position or move to different user areas such as the living room and the bedroom set by the user. Under the patrol purification tasks, the pet air purifier will move around the house to perform purification work and carry out patrol purification in all directions of the house. The local area (for example, the living room and the bedroom) and the whole area of the house belong to the purification range.

[0090] Step S308: Obtain the map, wherein the map is constructed by using the ultra-wideband indoor positioning technology and the laser radar sensor carried in the air purifier.

[0091] Step S309: Control the air purifier to execute the normal purification tasks in the determined purification range according to the map.

[0092] Since the purification tasks of the pet air purifier in the common purification mode are common purification tasks which are executed by the user actively, the priorities of different common purification tasks are the same.

[0093] In conclusion, the control method of the air purifier has the following beneficial effects:

[0094] (1) The active air management is realized through the switching of the common mode and the guardian mode. The common mode supports the user to manually control the conventional purification task, and the guardian mode relies on the UWB indoor positioning system and the laser radar SLAM technology to construct a high-precision map and obtain the pet position information in real time through the intelligent pet collar, combines the pet behavior analysis and the air quality sensor, and automatically triggers the guardian purification task and the alarm task. Meanwhile, the multi-level task priority management is adopted to support the task interruption recovery and the user-defined sorting, and ensure that the emergency event is responded preferentially.

[0095] (2) According to the characteristics of different pets, the personalized purification scheme can be generated, the user can further edit and optimize the related purification parameters on this basis, and the feedback on the purification effect can be made after the completion of the purification task, and the pet air purifier will automatically optimize the purification scheme according to the feedback result, so as to achieve the best purification experience and purification effect of each pet.

[0096] (3) Through the GPS outdoor positioning technology and the UWB indoor positioning technology, the intelligent safety alarm system for pets is innovatively designed. The system contains a double protection mechanism: one is the going-out alarm, which monitors the pets that go out without authorization in real time through the collar, and pushes the positioning information to the user as soon as the pet leaves the house, and can remotely trigger the sound and light prompt of the collar to assist in finding; the other is the forbidden area alarm, when the pet mistakenly enters the bedroom and other forbidden areas, the purifier can actively move to the scene, guide the pet to return to the safe area through the combination of sound and light or release the attractive smell (such as cat mint).
