DETAILED DESCRIPTION

[0021] In order to enable persons skilled in the art to more fully understand the features and technical contents of the embodiments of the present disclosure, the implementation of the embodiments of the present disclosure is described in detail below with reference to the accompanying drawings, which are used only for reference and are not intended to limit the embodiments of the present disclosure. In the following technical description, in order to facilitate explanation, a plurality of details are provided to provide a full understanding of the disclosed embodiments.

It should be understood that the data thus used can be interchanged under appropriate circumstances in order to implement the embodiments of the present disclosure described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0023] Unless otherwise specified, the term "a plurality of" means two or more.

[0024] In the embodiments of the present disclosure, the character " / " represents an "or" relationship between the objects before and after it. For example, A / B represents: A or B.

[0025] The term "and / or" is a description of the association relationship between objects, which means that there can be three relationships. For example, A and / or B means: A or B, or, A and B, the three relationships.

[0026] The term "corresponding" can refer to an association relationship or a binding relationship. A and B correspond to each other means that there is an association relationship or a binding relationship between A and B.

[0027] The current whole-house sterilization technical solutions mainly fall into three categories: 1) single-device independent sterilization solution, in which the air conditioner handles the evaporator surface pollutants through self-cleaning function, and the air purification device achieves air purification through UV-C irradiation, ion generation, etc.; 2) basic linkage solution, in which the air conditioner and the air purification device are time-sequentially linked through the smart home platform; and 3) single disinfection technology deepening solution, in which the ultraviolet disinfection, photocatalyst catalytic oxidation, ozone disinfection, etc. are continuously optimized, and have the convenience functions such as intelligent sensing avoidance and remote control. At present, the problems of low efficiency and complicated operation of traditional manual disinfection have been preliminarily solved, and the automation and basic intelligence of the sterilization process have been realized.

[0028] However, there are still many core bottlenecks to be solved in the prior art. For example, the single-device function limitation leads to a cleaning blind area, the air conditioner self-cleaning can only handle the local evaporator, and the residual microorganisms are easy to spread with the airflow, while the air purification device lacks targeted disinfection strategies when running independently, and the disinfection effect on specific pathogens is limited.

[0029] The present application constructs a deep linkage system of air conditioner and air purification device, takes the completion of air conditioner self-cleaning as the linkage trigger point, obtains the species, concentration and position information of residual microorganisms through the microorganism detection device built-in the air conditioner, breaks through the limitation of traditional single-index linkage. Through the establishment of a space model based on the three-dimensional layout data of the room, the airflow path and the sterilization blind area are accurately calculated to avoid equipment operation conflicts. Through local encrypted calculation, a customized sterilization strategy is generated, which matches the exclusive sterilization mode for different pathogens, and at the same time, the space model is dynamically adjusted to adjust the air outlet angle and operation parameters of the equipment. Finally, through the encrypted communication between the equipment, the strategy is synchronized to be executed, the sterilization effect is monitored in real time, and the closed-loop optimization is realized.

[0030] In combination with Figure 1 The present application provides a sterilization method, which comprises: S101, after the completion of air conditioner self-cleaning, controlling the air conditioner to detect residual microorganisms and obtaining residual microorganism information.

[0031] S102, establishing a room space model according to the layout of the room.

[0032] S103, generating a target sterilization strategy according to the residual microorganism information and the room space model.

[0033] S104, controlling the air purification device to execute the target sterilization strategy.

[0034] The method provided by the embodiments of the present disclosure can trigger the built-in microorganism detection device after the air conditioner completes self-cleaning, detect the residual microorganisms on the surface of the evaporator and the surrounding area, and obtain the residual microorganism information; then, the pre-stored room layout diagram is called, a three-dimensional room space model is constructed through an algorithm, the airflow path in the room, the area prone to forming a dead angle, and the relative action range of the air conditioner and the air purification equipment are determined; then, the residual microorganism information and the room space model are combined to generate a target sterilization strategy. The residual microorganism information can match a special sterilization mode, and the room space model can adjust the air purification equipment air outlet angle, air speed, and operation time, thereby avoiding air flow conflict with the air conditioner. Finally, the strategy is sent to the air purification equipment to control the execution of the sterilization operation, and the indoor microorganism concentration is monitored in real time to ensure that the standard is met. The method can perform more accurate sterilization operation on specific bacteria based on the microorganism detection result, thereby effectively improving the efficiency of whole-house sterilization. Meanwhile, the method can also solve the problem of uneven sterilization caused by single equipment cleaning blind area and air flow conflict, and achieve more thorough whole-house sterilization effect.

[0035] Specifically, the air purification equipment can be an air purifier, an ultraviolet disinfection device, a photocatalyst disinfection device, or an ozone disinfection device.

[0036] Optionally, the residual microorganism information includes the type and concentration of the residual microorganism. After the air conditioner completes self-cleaning, the residual microorganism detection is performed to obtain the residual microorganism information, including: after the air conditioner completes self-cleaning, performing infrared spectrum analysis on the evaporator of the air conditioner; identifying the type of the residual microorganism according to the infrared spectrum analysis result, and estimating the concentration of the residual microorganism.

[0037] In the embodiments of the present disclosure, after the air conditioner completes the self-cleaning program, the system automatically triggers the infrared spectrum detection module built in the air conditioner to perform infrared spectrum scanning on the surface of the evaporator and the surrounding area of the air conditioner, obtains the infrared spectrum characteristics of the substances on the surface of the evaporator by emitting infrared light of a specific wavelength and receiving the reflected signal; then, the collected infrared spectrum data is compared with a pre-set microorganism spectrum database, the specific type of the residual microorganism is accurately identified according to the difference in the spectrum absorption peak of different microorganisms (such as Legionella, Aspergillus, Staphylococcus, etc.), the concentration value of the residual microorganism is estimated based on the corresponding relationship model between the intensity of the spectrum signal and the concentration of the microorganism, and the area parameter of the detection area of the evaporator, and finally the identified type of the microorganism and the estimated concentration value are integrated to form complete residual microorganism information. The embodiments of the present disclosure realize the double-precision detection of the type and concentration of the residual microorganism through infrared spectrum analysis, provide core data support for subsequent customized sterilization strategy, avoid the problem of blind sterilization of the air purification equipment, ensure that the subsequent sterilization operation can be targeted to match the characteristics of the microorganism, greatly improve the precision and effectiveness of sterilization, and provide a quantitative basis for judging whether the sterilization effect meets the standard.

[0038] Optionally, the room space model is established according to the layout map of the room, comprising: calculating the relative positions and spatial volumes of the devices in the room according to the layout map of the room; and establishing the room space model according to the relative positions and spatial volumes.

[0039] In the embodiments of the present disclosure, first, the system calls a pre-stored room layout map, which contains the length, width and height size data of the room, and the position coordinates and size parameters of the devices in the room, including air conditioners, air purification devices, furniture (such as sofas, wardrobes, bed sets) and other objects; then, a three-dimensional coordinate system is established with a fixed point on the floor of the room (such as the position directly below the air conditioner installation) as the coordinate origin, the position coordinates of each object in the layout map are converted into coordinate values in the three-dimensional coordinate system, the relative position relationship between the air outlet of the air conditioner and the air purification device is determined by calculating the straight-line distance and the included angle between them, and the effective space volume of the room in which the air can flow and the range of the airflow obstruction area formed by the furniture are calculated according to the overall size of the room and the volume of each object; finally, based on the above relative position data, effective space volume data and airflow obstruction area data, a room space model containing device positions, spatial structures and potential airflow paths is constructed. By establishing a three-dimensional room space model, the airflow hedging problem is avoided, providing spatial data support for subsequent calculation of the optimal air outlet angle of the air purification device, ensuring that the air purification device killing airflow can form a collaborative convection with the air supply of the air conditioner, covering every corner of the room, effectively eliminating airflow dead angles, improving the uniformity of whole-house sterilization, and solving the problem of excessive concentration of corner bacteria in the traditional scheme.

[0040] Optionally, the target sterilization strategy includes a target sterilization mode, a target wind direction angle or a target irradiation angle, and the target sterilization strategy is generated according to the residual microorganism information and the room space model, comprising: obtaining the target sterilization mode matched with the residual microorganism information from the knowledge base according to the type and concentration of the residual microorganism; and calculating the target wind direction angle or the target irradiation angle of the air purification device according to the room space model.

[0041] In the embodiments of the present disclosure, on the one hand, the system calls a pre-set knowledge base, which stores matching rules of different microorganism types and corresponding sterilization modes (such as matching “UV-C irradiation + high-concentration ion generation” mode for Legionella, and matching “catalytic oxidation + medium-speed wind” mode for Aspergillus), and adjusts the sterilization intensity according to the concentration data of the residual microorganism (such as higher UV-C power and longer ion generation time for high-concentration microorganisms), so as to screen out the target sterilization mode completely matched with the current residual microorganism information.

[0042] In another aspect, in the case of the air purification device being an air purifier, a photocatalyst disinfection device, or an ozone disinfection device, the embodiments of the present disclosure calculate a target wind direction angle of the air purification device according to the room space model. Based on the relative positions of the air conditioner and the air purification device, the room size, and the airflow obstruction area data in the room space model, the airflow diffusion paths under different air outlet angles of the air purification device are calculated through a fluid mechanics simulation algorithm, the angles that will form a head-on collision with the air supply of the air conditioner (such as the air outlets of the two facing each other) or cannot cover the dead angle are excluded, and the target wind direction angle that can make the disinfection airflow efficiently cover the whole house and cooperate with the airflow of the air conditioner (such as the air outlet of the air purification device facing northeast when the air outlet of the air conditioner faces east, forming complementary airflows) is determined.

[0043] In the case of the air purification device being a UV disinfection device, the embodiments of the present disclosure calculate a target irradiation angle of the air purification device according to the room space model. First, key parameters such as the three-dimensional size of the room, the furniture obstruction area, the air outlet position of the air conditioner, and the air supply direction are extracted based on the room space model, the airflow dead angle and the microorganism residual aggregation area are labeled through fluid mechanics simulation, and then the light source irradiation angle required by the air purification device is calculated. The UV device needs to ensure that the light covers the microorganism aggregation area and the evaporator periphery, and the final target irradiation angle is determined. In this way, the problem of UV being blocked is effectively avoided, the disinfection dead angle is eliminated, the uniformity of whole-house disinfection is improved, and the targeting and overall effect of cross-device collaborative sterilization are greatly improved.

[0044] Finally, the determined target disinfection mode, target wind direction angle, or target irradiation angle are integrated to form a complete target disinfection strategy. On the one hand, the problem of ineffective disinfection is solved by matching the exclusive disinfection mode, greatly improving the disinfection rate of specific microorganisms; on the other hand, by optimizing the wind direction angle or the irradiation angle, the disinfection effect is ensured to cover the whole house, further improving the uniformity of sterilization, and reducing the energy waste caused by airflow conflict.

[0045] Optionally, the sterilization method further includes: adjusting the target disinfection strategy according to the current time; and controlling the air purification device to execute the adjusted target disinfection strategy.

[0046] In combination Figure 2 with the above, the embodiments of the present disclosure provide another sterilization method, which includes: S201, after the air conditioner self-cleaning is completed, residual microorganism detection is performed to obtain residual microorganism information.

[0047] S202, a room space model is established according to a layout diagram of the room.

[0048] S203, a target disinfection strategy is generated according to the residual microorganism information and the room space model.

[0049] S204, the target disinfection strategy is adjusted according to the current time.

[0050] S205, controlling the air purification device to execute the adjusted target sterilization strategy.

[0051] In the embodiments of the present disclosure, after the initial target sterilization strategy is generated, the system automatically acquires current time information, adjusts the initial target sterilization strategy according to the scene type to which the current time belongs, and after the adjustment is completed, the system sends the adjusted target sterilization strategy to the air purification device through encrypted communication, and controls the air purification device to execute the sterilization operation according to the adjusted parameters (such as the adjusted wind speed, power, time length, and air outlet angle). This step realizes the time dynamic adaptation of the sterilization strategy, so that the sterilization operation can meet the use requirements of users at different times, improve the user experience, and optimize the operation parameters according to the time scene, thereby further reducing unnecessary energy consumption on the premise of ensuring the sterilization effect.

[0052] Optionally, adjusting the target sterilization strategy according to the current time comprises: determining whether the current time is a power grid peak time; in the case that the current time is the power grid peak time, reducing the operation power corresponding to the target sterilization strategy; and in the case that the current time is not the power grid peak time, maintaining the operation power corresponding to the target sterilization strategy.

[0053] In the embodiments of the present disclosure, first, the system acquires the current time, calls the power grid peak and valley period division data, and determines whether the current time is in the peak time interval; if it is determined that the current time is the power grid peak time (at this time, the electricity price is high and the power grid load is large), the energy consumption optimization adjustment is started, the operation power of the air purification device in the target sterilization strategy is reduced according to the preset peak time adjustment algorithm (for example, from 100% of the rated power to 70%), so as to ensure that the power can be reduced to reduce energy consumption and electricity charges; if it is determined that the current time is not the power grid peak time (i.e., the valley time or the flat section, the electricity price is low and the power grid load is small), the operation power corresponding to the initial target sterilization strategy is maintained unchanged, and the sterilization operation is efficiently executed at the rated power. The embodiments of the present disclosure, on the one hand, effectively reduce the sterilization energy consumption and user electricity charges in the peak time high electricity price period through the peak time power reduction strategy, and on the other hand, ensure the sterilization efficiency by maintaining the rated power in the valley time, thereby avoiding the influence of excessive energy saving on the sterilization effect.

[0054] Optionally, the sterilization method further comprises: after the air purification device executes the target sterilization strategy, collecting real-time air quality data and determining whether the real-time air quality data is lower than a safety threshold; in the case that the real-time air quality data is lower than the safety threshold, generating a sterilization report; wherein the sterilization report comprises residual microorganism information, the target sterilization strategy, and the real-time air quality data; and in the case that the real-time air quality data is higher than or equal to the safety threshold, controlling the air purification device to execute an enhanced sterilization mode.

[0055] In combination with Figure 3As shown, the embodiments of the present disclosure provide another sterilization method, comprising: S301, after the air conditioner self-cleaning is completed, residual microorganism detection is performed to obtain residual microorganism information.

[0056] S302, according to the layout of the room, a room space model is established.

[0057] S303, according to the residual microorganism information and the room space model, a target sterilization strategy is generated.

[0058] S304, the air purification equipment is controlled to execute the target sterilization strategy.

[0059] S305, after the air purification equipment executes the target sterilization strategy, real-time air quality data is collected and it is judged whether the real-time air quality data is lower than a safety threshold.

[0060] S306, in the case that the real-time air quality data is lower than the safety threshold, a sterilization report is generated; wherein the sterilization report includes the residual microorganism information, the target sterilization strategy and the real-time air quality data.

[0061] S307, in the case that the real-time air quality data is higher than or equal to the safety threshold, the air purification equipment is controlled to execute an enhanced sterilization mode.

[0062] In the embodiments of the present disclosure, after the air purification equipment starts to execute the target sterilization strategy, the system controls the air quality detection module (such as PM2.5 sensor, microorganism sensor) built in the air purification equipment to collect indoor air data in real time, including real-time microorganism concentration, PM2.5 value, etc., to form real-time air quality data; then, the collected real-time air quality data is compared with the preset safety threshold; if the real-time data is lower than the safety threshold, it means that the sterilization effect meets the standard, the system automatically integrates the key information in this sterilization process, including the initial residual microorganism information (type, concentration), the executed target sterilization strategy (sterilization mode, air outlet angle, running parameter), the real-time air quality data (standard data), generates a structured sterilization report, and pushes it to the user terminal (such as mobile phone APP) through the smart home platform for the user to view. If the real-time data is higher than or equal to the safety threshold, it means that the current sterilization effect does not meet the standard, the system immediately triggers the enhanced sterilization mode, adjusts the running parameter of the air purification equipment (such as increasing the sterilization power, switching to a more efficient sterilization module combination, prolonging the running time), controls the air purification equipment to continue sterilization in the enhanced mode until the real-time data is lower than the safety threshold.

[0063] On the one hand, by monitoring in real time and judging whether the standard is met, the sterilization effect conforming to the safety standard is ensured, and the problem of incomplete sterilization and disinfection is avoided; on the other hand, by generating a sterilization report, the user's right to know and trust for the sterilization process is improved. At the same time, the triggering mechanism of the sterilization and disinfection mode is enhanced, which can cope with complex pollution scenes that are not covered by the initial strategy, further guarantee the safety of the air in the whole house, and improve the reliability and adaptability of the system.

[0064] Optionally, the sterilization method further comprises: after obtaining the residual microorganism information, performing encryption processing on the residual microorganism information; and before generating the target sterilization and disinfection strategy according to the residual microorganism information and the room space model, performing decryption processing on the encrypted residual microorganism information.

[0065] In combination Figure 4 According to the sterilization method provided in the embodiments of the present disclosure, the residual microorganism information is obtained after the air conditioner self-cleaning is completed, and the residual microorganism information is encrypted, so that the residual microorganism information is protected, and the user's right to know and trust for the sterilization process is improved. S401, after the air conditioner self-cleaning is completed, residual microorganism detection is performed to obtain residual microorganism information.

[0066] S402, after obtaining the residual microorganism information, performing encryption processing on the residual microorganism information.

[0067] S403, according to the layout map of the room, a room space model is established.

[0068] S404, before generating the target sterilization and disinfection strategy according to the residual microorganism information and the room space model, performing decryption processing on the encrypted residual microorganism information.

[0069] S405, according to the residual microorganism information and the room space model, a target sterilization and disinfection strategy is generated.

[0070] S406, controlling the air purification equipment to execute the target sterilization and disinfection strategy.

[0071] In the embodiments of the present disclosure, after the air conditioner obtains the residual microorganism information (type, concentration) by detection, the system immediately calls the built-in encryption algorithm (such as the AES encryption algorithm) to perform encryption processing on the residual microorganism information, converts the plaintext microorganism data into ciphertext data that cannot be directly interpreted, and prevents the data from being stolen or tampered with during transmission or storage. Subsequently, the encrypted residual microorganism information is transmitted through the encrypted communication link (such as encrypted WiFi, Bluetooth) between the air conditioner and the smart home platform (or air purification equipment). After the smart home platform (or air purification equipment) receives the encrypted data, before performing the target sterilization strategy generation step, the system calls the corresponding decryption algorithm, combines the preset key (which is only stored in the local device security area and is not uploaded to the cloud), and performs decryption processing on the encrypted residual microorganism information to restore it to plaintext microorganism data for subsequent matching of sterilization methods and generation of strategies. The entire encryption and decryption process is completed in the security area of the local device and does not rely on cloud processing. The problem of privacy leakage caused by uploading microorganism data and room data to the cloud in the traditional scheme is effectively solved. Through local encryption and decryption, the security of the residual microorganism information during transmission and processing is ensured, preventing hackers from stealing user home air health data or inferring home environment information through data, and protecting user privacy and security.
