[0001] This invention relates to the field of household appliance technology, and in particular to an intelligent health monitoring system and method for air conditioners. Background Technology
[0002] Since its invention in the early 20th century, air conditioners have evolved from simple cooling to comprehensive temperature control, and from manual operation to intelligent interconnection, gradually becoming an indispensable home appliance in modern life. With the increasing demand for healthy living, smart air conditioners have begun to integrate functions that monitor people's health.
[0003] Currently, air conditioners mainly create a healthy and comfortable indoor environment for users by monitoring indoor air quality, temperature, humidity, etc., and some smart air conditioners can also remind users to replace air filters, etc.
[0004] However, this monitoring method mainly relies on the monitoring and regulation of environmental parameters, lacking direct monitoring of individual physiological conditions, and has certain shortcomings in terms of accuracy and personalized health management. Summary of the Invention
[0005] This invention provides an intelligent health monitoring system and method for air conditioning, which addresses the shortcomings of existing technologies that rely on monitoring and adjusting environmental parameters, resulting in a lack of precise health management. By monitoring changes in indoor human body surface temperature, it achieves rapid health detection, providing strong technical support for health and safety.
[0006] This invention provides an intelligent health monitoring system for air conditioning, comprising: a temperature acquisition module for acquiring infrared radiation from the human body surface indoors to obtain a temperature image; a main control processing module for performing health detection based on the temperature image to obtain health detection results; and an early warning feedback module for generating early warning information based on the health detection results indicating the presence of abnormal temperature locations, and sending the early warning information to the user terminal for early warning notification.
[0007] It should be noted that by collecting infrared radiation from the human body surface indoors, changes in body temperature can be monitored. By analyzing the detected temperature images, abnormal temperature changes can be detected in a timely manner, which helps to identify potential health problems early and provides timely warnings when abnormal temperature areas are detected. While achieving rapid health detection, it also allows users to understand their own health status in a timely manner, providing strong technical support for health and safety, and improving people's health management level.
[0008] According to the present invention, an intelligent health monitoring system for air conditioning includes a main control processing module comprising: a feature extraction unit for extracting features from a temperature image to obtain a temperature feature map; an image segmentation unit for separating human body parts from the image background in the temperature image based on the temperature feature map using a preset segmentation algorithm to obtain a human body temperature feature map; a target detection unit for performing target detection on the human body temperature feature map to obtain a body part detection result; and a health detection unit for performing temperature detection on the human body temperature feature map based on the body part detection result to determine whether there is a health risk and obtain a health detection result.
[0009] It should be noted that the feature extraction unit quickly identifies and extracts important features from the temperature image to provide key information for subsequent processing; the image segmentation unit accurately separates human body parts from the background to reduce background interference and improve the accuracy of subsequent analysis; the target detection unit accurately identifies different parts of the human body to provide location information for health detection; and the health detection unit combines the body part detection results with the human body temperature feature map to comprehensively assess the human body's health status.
[0010] According to the present invention, an intelligent health monitoring system for air conditioning includes a health detection unit comprising: a temperature detection subunit, which performs temperature detection on a human body temperature characteristic map based on the detection results of body parts to obtain the temperature distribution characteristics of each body part; and a health detection subunit, which determines whether the temperature distribution characteristics of each body part exceed the corresponding preset temperature threshold based on the temperature distribution characteristics of each body part and the preset temperature threshold for the corresponding body part. If the temperature distribution characteristics exceed the preset temperature threshold, the health detection result is determined to indicate that there is a health risk in the corresponding body part; otherwise, the health detection result is determined to indicate that there is no health risk in the corresponding body part.
[0011] It should be noted that the temperature detection unit performs temperature detection on the human body temperature distribution characteristic map based on the detection results of body parts. This allows the health detection subunit to accurately determine whether the corresponding temperature is abnormal in combination with the body parts, thereby facilitating the timely detection of health problems in body parts and realizing personalized detection of health risks in different parts.
[0012] According to the present invention, an intelligent health monitoring system for air conditioning includes a target detection unit comprising: a key point detection subunit for detecting key points in a human body temperature feature map to obtain key point detection results; a temperature distribution recognition subunit for recognizing local temperatures at key points in the human body temperature feature map based on the key point detection results to obtain local temperature distribution results at key points; a feature matching subunit for matching the local temperature distribution results at key points with local temperature distribution features at key points in a preset template library to obtain matching results; and a target detection subunit for, based on the matching results indicating successful key point matching, using the corresponding key point as a seed point and employing a preset region growing algorithm to divide the human body temperature feature map into body parts to obtain body part detection results.
[0013] It should be noted that key point detection is performed by the key point detection subunit so that the temperature distribution recognition subunit can identify the local temperature distribution of the key points based on the detected key points. This allows for more accurate identification and location of various parts of the human body. Furthermore, by matching the local temperature distribution of key points, the accuracy of part identification is improved. Then, based on the successfully matched key points, the region growing algorithm is used to divide the body parts, thereby effectively expanding from key points to the entire body parts and improving the efficiency and completeness of detection.
[0014] According to the present invention, an intelligent health monitoring system for air conditioning includes an image segmentation unit comprising: a threshold determination subunit, which selects a preset threshold as a segmentation threshold, or obtains an adaptive threshold based on temperature characteristics using the maximum inter-class variance method or the minimum intra-class variance method, and uses this threshold as a segmentation threshold; a pixel classification subunit, which compares the temperature value corresponding to each pixel in the temperature feature map with the segmentation threshold, and if the temperature value corresponding to the pixel is greater than the segmentation threshold, classifies the corresponding pixel as a foreground pixel; otherwise, classifies the corresponding pixel as a background pixel; and an image segmentation subunit, which performs image segmentation on the temperature feature map based on the foreground pixels and background pixels to obtain a human body temperature feature map corresponding to the foreground pixels.
[0015] It should be noted that the threshold determination subunit selects a preset threshold or an adaptive threshold obtained using the maximum inter-class variance method, and the pixel classification subunit quickly classifies all pixels according to the threshold selected by the threshold determination subunit to ensure the efficiency of the entire segmentation process. Thus, the image segmentation subunit generates clear foreground and background separation based on accurate threshold determination and pixel classification, improving the accuracy of subsequent analysis. This allows subsequent target detection and health detection to focus on the analysis of human body parts, reducing computational complexity and processing time.
[0016] According to the present invention, an intelligent health monitoring system for air conditioning includes a threshold determination subunit, comprising: a statistical subunit, which determines the number of pixels corresponding to each temperature value based on a temperature feature map, and obtains a histogram, wherein each element in the histogram represents the number of pixels corresponding to the temperature value in the temperature feature map; a mean determination subunit, which determines the global temperature mean based on the histogram; and an initialization configuration subunit, which initializes the number of background pixels based on the number of pixels in all elements of the histogram, initializes the mean of background pixels based on the global temperature mean, and initializes the number of foreground pixels, the mean of foreground pixels, the variance of foreground pixels, and the variance of background pixels. The initial threshold is 0; the data processing subunit iterates through the temperature values corresponding to each element in the histogram, uses the iterated temperature value as the current threshold, compares the temperature values corresponding to the remaining elements with the current threshold, updates the number of foreground pixels, the mean foreground pixels, the number of background pixels, and the mean background pixels, and determines the intra-class variance or inter-class variance corresponding to the current threshold based on the updated number of foreground pixels, the mean foreground pixels, the number of background pixels, and the mean background pixels; the threshold determination subunit selects the threshold corresponding to the minimum intra-class variance or the maximum inter-class variance based on the intra-class variance or inter-class variance corresponding to the current threshold, and uses it as the adaptive threshold.
[0017] It should be noted that by statistically analyzing and calculating the histogram features of the image, initializing, traversing, and iteratively updating the statistical information of the foreground and background pixels, the adaptive threshold can be automatically adjusted according to the specific features of the temperature feature map. Furthermore, by calculating the intra-class or inter-class variance, the optimal threshold can be selected in the presence of noise, reducing the impact of noise on the segmentation results. This provides an accurate adaptive threshold for image segmentation, achieving effective separation of the foreground and background, improving the accuracy of image segmentation, and thus significantly improving the performance and practicality of the entire health monitoring system.
[0018] According to the present invention, an intelligent health monitoring system for air conditioning includes a temperature acquisition module comprising: an infrared sensor array unit for acquiring infrared radiation from the human body surface in an indoor target area to obtain an infrared temperature signal; a signal conditioning and amplification unit for amplifying and filtering the infrared temperature signal to obtain a conditioned and amplified signal; an analog-to-digital conversion unit for performing analog-to-digital conversion on the conditioned and amplified signal to obtain a digital temperature signal; and an image processing unit for setting the pixels in the corresponding indoor target area to the corresponding grayscale value according to the digital temperature signal and the corresponding indoor target area to obtain a temperature image.
[0019] It should be noted that the infrared sensor array unit accurately captures temperature changes on the human body surface, providing a reliable data foundation for subsequent health monitoring. The signal conditioning and amplification unit amplifies and filters the signal to improve its stability and signal-to-noise ratio, ensuring the accuracy of the temperature data. The analog-to-digital conversion unit converts the analog infrared signal into a digital signal, making the signal easier to store, transmit, and process, and less susceptible to external interference. The temperature image generated by the image processing unit intuitively displays the temperature distribution on the human body surface, facilitating the rapid identification of abnormal temperature areas and laying a solid data foundation for intelligent health monitoring and early warning.
[0020] According to the present invention, an intelligent health monitoring system for air conditioning includes a main control processing module, which further includes a data preprocessing unit for preprocessing the temperature image before performing health detection based on the temperature image. The preprocessing includes at least one of noise filtering and temperature calibration.
[0021] It should be noted that by preprocessing the temperature image to improve the signal-to-noise ratio, the temperature data becomes more accurate, providing a clear and accurate temperature image for subsequent health monitoring. This improves the accuracy of the entire health monitoring process, reduces false alarms caused by image noise or calibration deviations, and enhances the reliability of the system.
[0022] According to the present invention, an intelligent health monitoring system for air conditioning includes an early warning feedback module comprising: an early warning information generation unit, which generates early warning information based on the presence of abnormal temperature locations in a health monitoring result, according to the abnormal temperature locations and corresponding abnormal temperature differences, and in conjunction with preset early warning information generation rules; wherein, the preset early warning information generation rules are used to limit the alarm methods adopted for different body parts and their corresponding abnormal temperature differences; and a feedback unit, which sends the early warning information to the user terminal to remind the user according to the alarm method corresponding to the early warning information.
[0023] It should be noted that the early warning information generation unit generates corresponding early warning information based on the location of abnormal temperature and the corresponding abnormal temperature difference, combined with preset early warning information generation rules, according to the importance of different body parts and the severity of abnormal temperature differences. The user is then notified through the feedback unit, enabling the user to understand their own health status in a timely manner, enhancing the user's attention to and participation in their own health, and promoting the formation of a healthy lifestyle.
[0024] The present invention also provides an intelligent health monitoring method for air conditioners, comprising: collecting infrared radiation from the surface of a human body indoors to obtain a temperature image; performing health detection based on the temperature image to obtain a health detection result; generating early warning information based on the presence of abnormal temperature areas according to the health detection result, and sending the early warning information to the user terminal for early warning notification.
[0025] It should be noted that by collecting infrared radiation from the human body surface indoors, changes in body temperature can be monitored. By analyzing the detected temperature images, abnormal temperature changes can be detected in a timely manner, which helps to identify potential health problems early and provides timely warnings when abnormal temperature areas are detected. While achieving rapid health detection, it also allows users to understand their own health status in a timely manner, providing strong technical support for health and safety, and improving people's health management level.

Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.
[0031] The following is combined Figures 1 to 2 A schematic diagram illustrating the structure of an intelligent health monitoring system for air conditioning according to the present invention is shown below. Figure 1 The system includes: Temperature acquisition module 11 acquires infrared radiation from the human body surface indoors to obtain temperature images; The main control processing module 12 performs health detection based on the temperature image and obtains the health detection results; The early warning feedback module 13 generates early warning information based on the health detection results indicating the presence of abnormal temperature areas, and sends the early warning information to the user terminal for early warning notification.
[0032] In this embodiment, the temperature acquisition module 11 includes: an infrared sensor array unit for acquiring infrared radiation from the human body surface in an indoor target area to obtain an infrared temperature signal; a signal conditioning and amplification unit for amplifying and filtering the infrared temperature signal to obtain a conditioned and amplified signal; an analog-to-digital conversion unit for performing analog-to-digital conversion on the conditioned and amplified signal to obtain a digital temperature signal; and an image processing unit for setting the pixels in the corresponding indoor target area to the corresponding grayscale value according to the digital temperature signal and the corresponding indoor target area to obtain a temperature image.
[0033] It should be noted that the infrared sensor array unit accurately captures temperature changes on the human body surface, providing a reliable data foundation for subsequent health monitoring. The signal conditioning and amplification unit amplifies and filters the signal to improve its stability and signal-to-noise ratio, ensuring the accuracy of the temperature data. The analog-to-digital conversion unit converts the analog infrared signal into a digital signal, making the signal easier to store, transmit, and process, and less susceptible to external interference. The temperature image generated by the image processing unit intuitively displays the temperature distribution on the human body surface, facilitating the rapid identification of abnormal temperature areas and laying a solid data foundation for intelligent health monitoring and early warning.
[0034] It should be added that the temperature acquisition module can take full advantage of the location of the air conditioning unit, being installed inside the indoor unit to capture the body surface temperature of people indoors. Additionally, the infrared sensor array unit includes a high-resolution infrared sensor array to capture body surface temperature, with a resolution accurate to 0.1℃, thereby improving detection accuracy.
[0035] Furthermore, the temperature acquisition module can continuously acquire temperature data according to a preset sampling frequency and transmit the data to the main control processing module at certain time intervals. The preset sampling frequency can be set according to health monitoring needs or user habits, and is not further limited here.
[0036] In one alternative embodiment, reference Figure 2 The temperature acquisition module 11 also includes a power supply regulator unit, which provides power and regulates the voltage for the infrared sensor array unit, the signal conditioning and amplification unit and the analog-to-digital conversion unit.
[0037] In addition, the main control processing module 12 includes: a feature extraction unit, which extracts features from the temperature image to obtain a temperature feature map; an image segmentation unit, which separates the human body parts in the temperature image from the image background using a preset segmentation algorithm based on the temperature feature map to obtain a human body temperature feature map; a target detection unit, which performs target detection on the human body temperature feature map to obtain body part detection results; and a health detection unit, which performs temperature detection on the human body temperature feature map based on the body part detection results to determine whether there is a health risk and obtain health detection results.
[0038] It should be noted that the feature extraction unit quickly identifies and extracts important features from the temperature image to provide key information for subsequent processing; the image segmentation unit accurately separates human body parts from the background to reduce background interference and improve the accuracy of subsequent analysis; the target detection unit accurately identifies different parts of the human body to provide location information for health detection; and the health detection unit combines the body part detection results with the human body temperature feature map to comprehensively assess the human body's health status.
[0039] In addition, the main control processing module can use a microprocessor to integrate data processing and control functions, and connect to the temperature acquisition module through a high-speed data bus, while controlling communication and early warning feedback.
[0040] Specifically, the image segmentation unit includes: a threshold determination subunit, which selects a preset threshold as the segmentation threshold, or obtains an adaptive threshold based on temperature features using the maximum inter-class variance method or the minimum intra-class variance method, and uses it as the segmentation threshold; a pixel classification subunit, which compares the temperature value corresponding to each pixel in the temperature feature map with the segmentation threshold. If the temperature value corresponding to the pixel is greater than the segmentation threshold, the corresponding pixel is classified as a foreground pixel; otherwise, the corresponding pixel is classified as a background pixel; and an image segmentation subunit, which performs image segmentation on the temperature feature map based on the foreground pixels and background pixels to obtain the human body temperature feature map corresponding to the foreground pixels.
[0041] It should be noted that the threshold determination subunit selects a preset threshold or an adaptive threshold obtained using the maximum inter-class variance method, and the pixel classification subunit quickly classifies all pixels based on the threshold selected by the threshold determination subunit. This ensures the efficiency of the entire segmentation process. Thus, by using precise threshold determination and pixel classification, the image segmentation subunit generates clear foreground and background separation, improving the accuracy of subsequent analysis. This allows subsequent target detection and health detection to focus on the analysis of human body parts, reducing computational complexity and processing time. Furthermore, the preset threshold can be configured based on human body temperature distribution characteristics or prior experience; the specific setting can be tailored to actual needs and is not further limited here.
[0042] Further, the threshold determination subunit includes: a statistical subunit, which determines the number of pixels corresponding to each temperature value based on the temperature feature map, and obtains a histogram, where each element in the histogram represents the number of pixels corresponding to the temperature value in the temperature feature map; a mean determination subunit, which determines the global temperature mean based on the histogram; an initialization configuration subunit, which initializes the number of background pixels based on the number of pixels in all elements of the histogram, initializes the mean of background pixels based on the global temperature mean, and initializes the number of foreground pixels, the mean of foreground pixels, the variance of foreground pixels, and the variance of background pixels to 0; and a data processing subunit. The first unit iterates through the temperature values corresponding to each element in the histogram, uses the iterated temperature value as the current threshold, and compares the temperature values corresponding to the remaining elements with the current threshold. It then updates the number of foreground pixels, the mean foreground pixels, the number of background pixels, and the mean background pixels. Based on the updated number of foreground pixels, the mean foreground pixels, the number of background pixels, and the mean background pixels, it determines the intra-class variance or inter-class variance corresponding to the current threshold. The second unit determines the threshold by selecting the threshold corresponding to the minimum intra-class variance or the maximum inter-class variance based on the intra-class variance or inter-class variance corresponding to the current threshold, and using this as the adaptive threshold.
[0043] It should be noted that by statistically analyzing and calculating the histogram features of the image, initializing, traversing, and iteratively updating the statistical information of the foreground and background pixels, the adaptive threshold can be automatically adjusted according to the specific features of the temperature feature map. Furthermore, by calculating the intra-class or inter-class variance, the optimal threshold can be selected in the presence of noise, reducing the impact of noise on the segmentation results. This provides an accurate adaptive threshold for image segmentation, achieving effective separation of the foreground and background, improving the accuracy of image segmentation, and thus significantly improving the performance and practicality of the entire health monitoring system.
[0044] In addition, the target detection unit includes: a key point detection subunit, which performs key point detection on the human body temperature feature map to obtain key point detection results; a temperature distribution recognition subunit, which performs local temperature recognition on key points on the human body temperature feature map based on the key point detection results to obtain local temperature distribution results for key points; a feature matching subunit, which matches the local temperature distribution results of key points with the local temperature distribution features of key points in a preset template library to obtain matching results; and a target detection subunit, which, based on the matching results showing that the key point matching is successful, uses the corresponding key point as a seed point and uses a preset region growing algorithm to divide the human body temperature feature map into body parts to obtain body part detection results.
[0045] It should be noted that key point detection is performed by the key point detection subunit so that the temperature distribution recognition subunit can identify the local temperature distribution of the key points based on the detected key points. This allows for more accurate identification and location of various parts of the human body. Furthermore, by matching the local temperature distribution of key points, the accuracy of part identification is improved. Then, based on the successfully matched key points, the region growing algorithm is used to divide the body parts, thereby effectively expanding from key points to the entire body parts and improving the efficiency and completeness of detection.
[0046] Furthermore, the target detection unit also includes a post-processing subunit, which can either ignore the corresponding key point if the key point is not matched successfully, or mark the corresponding key point for subsequent manual review or other processing. The specific settings can be configured according to actual design requirements, and no further limitations are made here.
[0047] In addition, the health detection unit includes: a temperature detection subunit, which performs temperature detection on the human body temperature characteristic map based on the detection results of body parts to obtain the temperature distribution characteristics of each body part; and a health detection subunit, which determines whether the temperature distribution characteristics of each body part exceed the corresponding preset temperature threshold based on the temperature distribution characteristics of each body part and the preset temperature threshold of the corresponding body part. If it exceeds the preset temperature threshold, the health detection result is determined to be that there is a health risk in the corresponding body part; otherwise, the health detection result is determined to be that there is no health risk in the corresponding body part.
[0048] It should be noted that the temperature detection unit performs temperature detection based on the body part detection results, analyzing the human body temperature distribution characteristic map. This allows the health detection subunit to accurately determine whether the corresponding temperature is abnormal, facilitating the timely detection of health problems in different body parts and enabling personalized health risk detection for different areas. Furthermore, the preset temperature threshold can be set based on the critical values between normal and abnormal temperatures for the corresponding body part; this will not be further elaborated upon here.
[0049] In an optional embodiment, the main control processing module further includes: a data preprocessing unit, which preprocesses the temperature image before performing health detection based on the temperature image, the preprocessing including at least one of noise filtering and temperature calibration.
[0050] It should be noted that by preprocessing the temperature image to improve the signal-to-noise ratio, the temperature data becomes more accurate, providing a clear and accurate temperature image for subsequent health monitoring. This improves the accuracy of the entire health monitoring process, reduces false alarms caused by image noise or calibration deviations, and enhances the reliability of the system.
[0051] In one optional embodiment, the early warning feedback module 13 includes: an early warning information generation unit, which generates early warning information based on the health detection result indicating the presence of an abnormal temperature location, according to the abnormal temperature location and the corresponding abnormal temperature difference, and in conjunction with preset early warning information generation rules; wherein, the preset early warning information generation rules are used to restrict the alarm methods adopted for different body parts and their corresponding abnormal temperature differences; and a feedback unit, which sends the early warning information to the user terminal to remind the user according to the alarm method corresponding to the early warning information.
[0052] It should be noted that the early warning information generation unit generates corresponding early warning information based on the location of abnormal temperature and the corresponding abnormal temperature difference, combined with preset early warning information generation rules, according to the importance of different body parts and the severity of abnormal temperature differences. The user is then notified through the feedback unit, enabling the user to understand their own health status in a timely manner, enhancing the user's attention to and participation in their own health, and promoting the formation of a healthy lifestyle.
[0053] It should be added that the early warning information generation unit is also used to generate a health alert message based on the health detection results indicating that there are no abnormal temperature areas, and send it to the user terminal using the feedback unit.
[0054] Furthermore, the preset warning information generation rules can be customized according to different users' needs and preferences, providing personalized alarm services. For example, if the temperature of a certain part of the body is abnormal, but the abnormal temperature difference is small, only a prompt message can be generated and sent to the user's terminal. If the abnormal temperature difference is large, a voice alarm can also be generated and sent to the user's terminal at the same time. The specific configuration can be based on actual user needs, and no further limitations are made here. In addition, the warning feedback module can initiate the transmission of warning signals within milliseconds, so that users can know about abnormal body temperature as soon as possible, thereby ensuring the real-time nature of message reminders.
[0055] In an optional embodiment, the system can communicate with the user terminal via a wireless network or Bluetooth to facilitate the transmission and feedback of early warning information.
[0056] In an optional embodiment, the system further includes a storage management module that stores temperature images, health detection results, and / or early warning information in local storage or uploads them to a cloud platform to facilitate subsequent statistical analysis of health data.
[0057] In summary, this invention collects infrared radiation from the surface of the human body indoors to monitor changes in body temperature. By detecting the obtained temperature images, abnormal temperature changes can be detected in a timely manner, which helps to identify potential health problems early and provides timely warnings when abnormal temperature areas are detected. This enables rapid health detection and allows users to understand their own health status in a timely manner, providing strong technical support for health and safety and improving people's health management level.
