Description

Technical Field

[0001] The present application relates to the technical field of vehicle air-conditioning control, and in particular to an air-conditioning control method, device, equipment and storage medium based on light tracking and human body recognition. Background Art

[0002] With the development of smart car technology, people have increasingly higher requirements for the comfort of the vehicle's interior environment. In the vehicle air-conditioning system, it is necessary to intelligently adjust the temperature and air volume according to the real-time needs of passengers and changes in the external environment. Especially in the hot summer, direct sunlight can cause uneven temperature inside the car, and passengers feel significant differences in body heat. This not only affects the ride comfort, but also has an impact on the health of passengers. Therefore, how to intelligently adjust the air outlet strategy based on the light and the passenger's body surface heat distribution is a must-do task.

[0003] At present, the existing practice is to calculate and control the air conditioning temperature and air volume based on the data of the temperature sensor arranged on the dashboard. The electric air outlet sweeps air according to a fixed program, and the air conditioning is controlled based on the air temperature detection inside the car.

[0004] However, in addition to the heat from contact with the air inside the car, the human body also experiences heat from direct sunlight. Existing practices do not take into account the impact of direct sunlight on passengers' perceived heat, nor can they adjust the air-conditioning system in real time based on changes in the passengers' body surface temperature. They cannot effectively address the problem of local overheating caused by direct sunlight. Passengers may feel uncomfortable in areas exposed to direct sunlight, for example, seats or backrests may become overheated. When the passenger's body surface temperature changes due to direct sunlight, the existing air-conditioning system cannot make corresponding adjustments, which will cause passengers to feel overheated or too cold in certain areas of the car. Therefore, how to perform intelligent air-conditioning control based on light tracking and human recognition has become an urgent problem to be solved.

[0051] The purpose, features and advantages of this application will be further explained with reference to the accompanying drawings in conjunction with the embodiments. DETAILED DESCRIPTION

[0052] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0053] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0054] The main solution of the embodiment of the present application is: detecting the sunlight-irradiated area to obtain light path information and human body information; calculating the overlap of the illumination area based on the light path information and the human body information to determine the perceived heat of the illumination area; tracking the human body heat distribution based on the perceived heat of the illumination area to control the intelligent air outlet of the air-conditioning outlet to complete the air-conditioning temperature adjustment.

[0055] In this embodiment, for ease of description, the following description is made by taking the identification of an air-conditioning control device based on light tracking and human body recognition as the execution subject.

[0056] Because existing technologies do not take into account the impact of direct sunlight on passengers' perceived heat, and are unable to adjust the air-conditioning system in real time according to changes in the passengers' body surface temperature, they are unable to effectively address the problem of local overheating caused by direct sunlight. Passengers may feel uncomfortable in areas exposed to direct sunlight. For example, the seats or backrests may become overheated. When the passengers' body surface temperature changes due to direct sunlight, the existing air-conditioning system is unable to make corresponding adjustments, which will cause passengers to feel overheated or too cold in certain areas of the car.

[0057] The present application provides a solution, which detects the sunlight-irradiated area to obtain light path information and human body information; calculates the overlap of the illumination area based on the light path information and the human body information to determine the perceived heat of the illumination area; and tracks the heat distribution of the human body based on the perceived heat of the illumination area to control the intelligent air outlet of the air conditioner to complete the air conditioning temperature adjustment.

[0058] It can be seen from the above embodiments that the present application obtains light path information and human body information by detecting the sunlight-irradiated area, and then calculates the overlap between the illumination area and the human body to determine the perceived heat, thereby tracking the heat distribution of the human body, and intelligently adjusts the direction, temperature and wind speed of the air-conditioning outlet to generate heat exchange in the designated area, thereby achieving a balance between energy acquisition and energy release, making the occupants feel comfortable, eliminating the burning sensation of the sun, and ensuring that passengers can enjoy a comfortable in-car experience under different environmental conditions, significantly improving the comfort and satisfaction of riding.

[0059] Based on this, the embodiment of the present application provides an air conditioning control method based on light tracking and human body recognition, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the air conditioning control method based on light tracking and human body recognition of this application.

[0060] In this embodiment, the air conditioning control method based on light tracking and human body recognition includes steps S10 to S30:

[0061] Step S10, detecting the sunlight irradiation area to obtain light path information and human body information;

[0062] It should be noted that the light path information reflects the distribution of sunlight in the vehicle and the characteristics of the illumination characteristics, and the human body information reflects the distribution positions and body shape characteristics of the occupants in the vehicle.

[0063] It is understandable that when booking a car, the light sensing device can be used to accurately obtain light path information, thereby determining the specific sunlight exposure area in the car, and the human body information can be obtained through the infrared camera, thereby determining the overlap between the human body and the sunlight exposure area, and performing personalized temperature adjustment and intelligent adjustment of the air conditioning output, so that passengers can enjoy a comfortable in-car experience under different environmental conditions, significantly improving the comfort and satisfaction of riding.

[0064] For ease of understanding, the acquisition of optical path information and human body information is taken as an example for explanation, wherein the information acquisition device is an information acquisition module, and the storage device is a memory.

[0065] The information acquisition module uses a light sensing device to obtain light brightness information and light angle information, and obtains occupant position information and occupant body shape information through an infrared camera, determines light path information based on the light brightness information and the light angle information, determines human body information based on the occupant position information and the occupant body shape information, stores the light path information and human body information in a memory, and performs subsequent processing based on the light path information and human body information.

[0066] In a feasible implementation, step S10 may include steps A11 to A13:

[0067] Step A11: using a light sensor to obtain light intensity information and light angle information, and using an infrared camera to obtain occupant position information and occupant body shape information;

[0068] It should be noted that the light illuminance information reflects the characteristics of the brightness of sunlight in a specific area inside the vehicle, the light angle information reflects the characteristics of the angle at which sunlight enters the vehicle, the occupant position information reflects the characteristics of the occupant's specific position inside the vehicle, and the occupant body shape information reflects the characteristics of the occupant's body size and shape.

[0069] Step A12, determining light path information based on the light illuminance information and the light angle information;

[0070] It can be understood that the level of the light brightness information directly affects the radiant heat received by the passengers in this area, and the light angle information determines the relative position of the sunlight and the surface inside the vehicle, thereby affecting the reflection, refraction and absorption of sunlight inside the vehicle, thereby evaluating the radiant heat received by the passengers, tracking the body heat distribution and adjusting the air conditioning outlet, thereby improving riding comfort.

[0071] Step A13: determining human body information based on the occupant position information and the occupant body shape information.

[0072] It can be understood that the occupant position information is used to determine whether the occupant is in direct sunlight and how much heat the occupant is exposed to, so as to adjust the air conditioning outlet in a targeted manner to meet the occupant's comfort needs, and the occupant body shape information can calculate the radiant heat received by the occupant and characterize the occupant's heat absorption state. Occupants of different body shapes have different heat absorption and dissipation capabilities, thereby achieving more personalized temperature control.

[0073] Step S20, calculating the overlap of the illuminated area based on the light path information and the human body information to determine the perceived heat of the illuminated area;

[0074] It should be noted that the perceived heat in the illuminated area reflects the characteristics of the total heat generated by the occupants in a specific area inside the vehicle due to direct sunlight.

[0075] It can be understood that the optical path information provides the distribution of sunlight in the car, while the human body information provides the position and body shape of the occupants, so that the intersection of the human body and the optical path can be calculated, that is, the overlap between the occupants and the direct sunlight area is calculated, and the human body light receiving area is obtained, and then the perceived heat of the illuminated area is calculated, so as to intelligently adjust the wind direction, temperature and wind speed of the air-conditioning outlet to adapt to the comfort needs of the occupants, provide a more personalized and comfortable riding environment, and enhance the satisfaction and comfort of the riding experience.

[0076] For ease of understanding, the following description is made by taking the determination of perceived heat in the illuminated area as an example, wherein the information collection device is the information collection module, the storage device is the memory, and the processing device is the processing module.

[0077] The information acquisition module obtains optical path information and human body information, obtains the degree of overlap between the optical path and the human body based on the optical path information and the human body information, calculates the intersection of the human body and the optical path to obtain the human body light spot area, and thus obtains the light wave light energy E, the area S of the photosensitive unit receiving light energy, the photosensitive unit reference resistance R0, the photosensitive unit resistance change standard value K, the brightness reference value I0, the brightness index n and the continuous irradiation time T based on the human body light spot area.

[0078] The brightness value is calculated based on the light wave light energy and the area of ​​the photosensitive unit receiving the light energy, that is, the light intensity per unit area is calculated as:

[0079] Where I is the applied light intensity, measured in lux (Lx), E is the light energy of the light wave, measured in joules (J), and S is the area of ​​the photosensitive unit that receives the light energy, measured in square meters (㎡).

[0080] The change in resistance of the photosensitive unit with light intensity can be obtained from a list of calibrated values ​​of the device. The resistance of the photosensitive unit in ohms is calculated based on the reference resistance of the photosensitive unit, the standard value of resistance change of the photosensitive unit, the brightness value, the brightness reference value, and the brightness index. That is, the resistance of the photosensitive unit is calculated as:

[0081]

[0082] Among them, R is the resistance of the photosensitive unit, the unit is ohm Ω, R0 is the base resistance of the photosensitive unit, the unit is ohm Ω, K is a constant used to indicate the degree of change in the resistance of the photosensitive unit, I is the applied light intensity, the unit is lux (Lx), I0 is the reference brightness value, an appropriate value can be selected as the reference value of the coefficient n, the specific value can be determined by calibration, the unit is lux (Lx), n is the exponential value of the light intensity, usually 2 or 3.

[0083] The heat gained by the human body spot area per unit time is calculated, and the perceived heat of the illuminated area is calculated based on the light wave energy and the continuous irradiation time, that is, the heat gained per unit area is calculated as:

[0084]

[0085] Where P is the energy obtained, i.e., the perceived heat in the illuminated area, in watts (W), E is the light energy of the light wave in joules (J), and T is the duration of exposure in seconds (s).

[0086] In reality, there are still multiple factors that can affect the perceived heat in the illuminated area, such as the skin color of the illuminated surface of the human body, the color of the clothing covering the surface, the thermal conductivity coefficient and the glass insulation coating, all of which can affect the actual perceived heat in the illuminated area obtained by the human body surface. It can be corrected according to the actual calibration results and the software parameters can be adjusted, which will not be elaborated here.

[0087] In a feasible implementation, step S20 may include steps B11 to B14:

[0088] Step B11, obtaining the light wave energy, the area of ​​the photosensitive unit receiving light energy, the photosensitive unit reference resistance, the photosensitive unit resistance change standard value, the brightness reference value, the brightness index and the continuous irradiation time;

[0089] It should be noted that the light wave light energy reflects the characteristics of the energy size carried by the light waves in the sunlight, the light energy receiving area of ​​the photosensitive unit reflects the characteristics of the size of the area where the photosensitive unit can receive light energy, the photosensitive unit reference resistance reflects the characteristics of the resistance value of the photosensitive unit in the absence of light or under standard lighting conditions, the photosensitive unit resistance change standard value reflects the characteristics of the predetermined range of resistance value change of the photosensitive unit under the action of light, the brightness reference value reflects the characteristics of the brightness value under standard lighting or reference lighting, the brightness index reflects the characteristics of the index of light intensity changing with light intensity, and the continuous illumination time reflects the characteristics of the time period when sunlight continuously irradiates the photosensitive unit.

[0090] Step B12, calculating a brightness value based on the light wave light energy and the area of ​​the photosensitive unit receiving light energy;

[0091] It should be noted that the brightness value reflects the intensity of light energy received per unit area.

[0092] It is understandable that the brightness value determines the radiation intensity of sunlight in the car, thereby affecting the passengers' perceived heat and comfort. By calculating the brightness value, the impact of sunlight on the car environment can be more accurately judged and the air-conditioning temperature can be adjusted more precisely.

[0093] Step B13, calculating the photosensitive unit resistance in ohms based on the photosensitive unit reference resistance, the photosensitive unit resistance change standard value, the brightness value, the brightness reference value, and the brightness index;

[0094] It should be noted that the photosensitive unit resistance value in ohms reflects the characteristics of the resistance value of the photosensitive unit under specific lighting conditions.

[0095] It can be understood that the photosensitive unit is a resistor element that is sensitive to light, and its resistance value will change with the change of light intensity. The change in the resistance value of the photosensitive unit can be used to accurately evaluate the light intensity, thereby intelligently adjusting the air conditioning outlet to ensure that passengers can enjoy a comfortable in-car environment under different lighting conditions.

[0096] Step B14: Calculate the perceived heat of the illuminated area based on the light wave energy and the continuous illumination time.

[0097] It can be understood that the perceived heat in the illuminated area can represent the heat actually felt by the occupants, thereby performing more precise temperature adjustment, reducing uneven temperature in the vehicle caused by prolonged sunlight, and providing a more comfortable riding environment.

[0098] Step S30 , based on the perceived heat in the illumination area, the heat distribution of the human body is tracked to control the air outlet of the air conditioner to intelligently discharge air to complete the air conditioner temperature adjustment.

[0099] It can be understood that if the calculated perceived heat of the illuminated area accumulates to the preset comfort threshold, that is, the perceived heat of the target illuminated area, the air outlet will automatically adjust the wind direction to the position where the sunlight directly hits the human body, and set the appropriate air outlet temperature and wind speed based on the real-time calculation of the sunlight energy per unit area per unit time, so that heat exchange occurs in the designated area, thereby achieving a balance between energy acquisition and energy release, making the occupants feel comfortable and eliminating the burning sensation of the sun.

[0100] For ease of understanding, the example of obtaining the perceived heat in the illuminated area is used for explanation, wherein the information collection device is the information collection module, the storage device is the memory, and the processing device is the processing module.

[0101] The information acquisition module obtains the perceived heat of the illuminated area and the perceived heat of the target illuminated area, determines the air conditioning cooling state based on the perceived heat of the illuminated area and the perceived heat of the target illuminated area, uses an infrared camera to obtain heat distribution photos, the heat distribution photos include heat distribution photos of entering the vehicle and seating, heat distribution photos after sun exposure, and heat comparison distribution photos, obtains target heat distribution photos, obtains the air conditioning cooling state and the heat source heat distribution state based on the heat distribution photos and the target heat distribution photos, thereby confirming the air conditioning cooling effect, and when the heat source heat distribution state is unevenly distributed and the air conditioning cooling state is insufficient in cooling effect, controls the air conditioning to lower the temperature, increase the air volume, extend the blowing time, and adjust the sweeping path, and when the heat source heat distribution state is unevenly distributed and the air conditioning cooling state is excessive in cooling effect, controls the air conditioning to increase the temperature, lower the air volume, reduce the blowing time, and adjust the sweeping path, and when the heat source heat distribution state is balanced in distribution, controls the air conditioning to stop cooling.

[0102] The air-conditioning control method based on light tracking and human body recognition proposed in this embodiment detects the sunlight-irradiated area to obtain light path information and human body information; calculates the overlap of the illumination area based on the light path information and the human body information to determine the perceived heat of the illumination area; and tracks the heat distribution of the human body based on the perceived heat of the illumination area to control the intelligent air outlet of the air-conditioning outlet to complete the air-conditioning temperature adjustment. It solves the technical problem of how to intelligently adjust the air conditioner for heat exchange. Compared with the existing technology, this application obtains light path information and human body information by detecting the sunlight-irradiated area, and uses light sensing devices and infrared cameras to accurately capture light intensity, angle, occupant position and body shape, and then calculates the overlap between the illumination area and the human body, determines the perceived heat, and intelligently adjusts the wind direction, temperature and wind speed of the air-conditioning outlet, significantly improving riding comfort and satisfaction. At the same time, it quickly responds to changes in the external environment, so that the air-conditioning system can actively adjust the corresponding blowing direction and blowing temperature according to the ambient light and human body surface heat distribution, bringing an intelligent and comfortable riding experience. According to the current sunlight conditions, targeted cooling is implemented for the parts of the car that are in contact with the human body and are exposed to sunlight, so that the temperature of the areas touched by passengers after getting on the car is suitable, avoiding the feeling of burning buttocks and hot hands, and alleviating the burning sensation of the human body caused by direct sunlight.

[0103] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction and will not be repeated later.

[0104] In this embodiment, refer to Figure 2 , Figure 2 This is a flow chart of the second embodiment of the air conditioning control method based on light tracking and human body recognition of this application. Step S30 specifically includes steps S31 to S33:

[0105] Step S31, obtaining the perceived heat of the target illumination area;

[0106] It should be noted that the perceived heat in the target illumination area reflects the characteristics of an artificially preset comfort threshold.

[0107] It can be understood that if the calculated perceived heat of the illuminated area reaches the perceived heat of the target illuminated area, the air-conditioning outlet position, air outlet temperature and wind speed will be intelligently adjusted. According to the actual perceived heat of the occupants, the air-conditioning outlet will be intelligently adjusted to provide a more personalized and comfortable riding environment.

[0108] For ease of understanding, the example of obtaining the perceived heat of the target illumination area is used for explanation, wherein the information acquisition device is the information acquisition module, the storage device is the memory, and the processing device is the processing module.

[0109] When reserving a car, the perceived heat of the target lighting area is set according to the human body's comfort threshold. The information acquisition module obtains the perceived heat of the target lighting area and stores it in the memory, and performs subsequent processing based on the perceived heat of the target lighting area.

[0110] Step S32, determining the air conditioning cooling state based on the sensible heat of the illumination area and the sensible heat of the target illumination area;

[0111] It should be noted that the air conditioning cooling state reflects the characteristics of the actual operating effect of the air conditioning.

[0112] It is understandable that the air conditioning cooling state represents the occupants' perceived comfort. The air conditioning system can adjust the air conditioning operating parameters based on the difference between the actually measured perceived heat in the illuminated area and the target value, realize intelligent temperature control, provide ideal temperature regulation effects, and ensure that occupants can enjoy a comfortable in-car environment under different external lighting conditions.

[0113] In addition, it should be noted that if Figure 3 As shown, Figure 3 This is a standard human body thermal imaging diagram of the air-conditioning control method based on light tracking and human body recognition in this application. The cooling effect of the air-conditioning can be confirmed by comparing the infrared camera with the heat distribution photos of the human body when entering the car and sitting down, the heat distribution photos of the human body after sun exposure, and the heat changes in the air-conditioning blowing area.

[0114] For ease of understanding, an example of determining the cooling state of an air conditioner is used for explanation, wherein the information collection device is an information collection module, the storage device is a memory, and the processing device is a processing module.

[0115] The information acquisition module obtains the perceived heat of the illuminated area and the perceived heat of the target illuminated area. If the perceived heat of the illuminated area is not lower than the perceived heat of the target illuminated area, the air outlet automatically adjusts the wind direction to the position where the sunlight directly hits the human body. The appropriate air outlet temperature and wind speed are set based on the real-time calculation of the sunlight energy obtained per unit area per unit time to generate heat exchange in the designated area. An infrared camera is used to take photos of the heat distribution of the human body when entering the car and sitting down, the heat distribution of the human body after sun exposure, and the heat changes in the air-conditioning blowing area. The photos are compared with the standard human body heat distribution to confirm the cooling effect of the air conditioner. If there is a difference with the standard human body thermal imaging diagram, it is determined that the cooling effect of the air conditioner cooling state is insufficient or excessive, and the cooling effect is enhanced or weakened. If there is no difference with the standard human body thermal imaging diagram, it is determined that the cooling effect of the air conditioner cooling state is satisfactory. At this time, the heat distribution state of the heat source is balanced, and subsequent processing is performed based on the air conditioner cooling state.

[0116] Step S33: adjusting the wind direction, temperature and wind speed of the air outlet of the air conditioner based on the cooling state of the air conditioner.

[0117] It can be understood that the air-conditioning outlet wind direction, temperature and wind speed can be intelligently adjusted based on the air-conditioning cooling status. The air-conditioning outlet can be intelligently adjusted according to the actual body heat felt by the passengers, providing a personalized comfort experience and improving the response speed and adjustment accuracy of the air-conditioning system.

[0118] For ease of understanding, the example of obtaining the cooling state of the air conditioner is used for explanation, wherein the information collection device is the information collection module, the storage device is the memory, and the processing device is the processing module.

[0119] The information acquisition module uses an infrared camera to obtain heat distribution photos, which include heat distribution photos of entering the vehicle and taking a seat, heat distribution photos after sun exposure, and heat comparison distribution photos. A target heat distribution photo is obtained, and the air conditioning cooling state and the heat source heat distribution state are obtained based on the heat distribution photos and the target heat distribution photos. When the heat source heat distribution state is unevenly distributed and the air conditioning cooling state is insufficient in cooling effect, the air conditioning is controlled to lower the temperature, increase the air volume, extend the blowing time, and adjust the wind sweeping path. When the heat source heat distribution state is unevenly distributed and the air conditioning cooling state is excessive in cooling effect, the air conditioning is controlled to increase the temperature, lower the air volume, reduce the blowing time, and adjust the wind sweeping path. When the heat source heat distribution state is balanced, the air conditioning is controlled to stop cooling.

[0120] In a feasible implementation, step S33 may include steps C11 to C13:

[0121] Step C11, using an infrared camera to obtain heat distribution photos, the heat distribution photos including heat distribution photos before entering the vehicle, heat distribution photos after sun exposure, and heat comparison distribution photos;

[0122] It should be noted that the heat distribution photos reflect the characteristics of the heat energy distribution state of the passengers and objects in the vehicle due to sunlight exposure, the heat distribution photos when entering the vehicle and sitting down reflect the characteristics of the heat distribution state when the passengers enter the vehicle and sit down, the heat distribution photos after sun exposure reflect the characteristics of the heat distribution state of the passengers or objects in the vehicle after direct sunlight exposure, and the heat comparison distribution photos reflect the characteristics of the difference between the heat distribution in the vehicle after air conditioning adjustment and the standard comfort state.

[0123] Step C12, determining the cooling state of the air conditioner and the heat distribution state of the heat source based on the heat distribution photo;

[0124] It can be understood that the air-conditioning system is adjusted based on the cooling state of the air-conditioning to bring the temperature inside the car to a comfortable range, including adjusting the air-conditioning operating mode, wind speed and temperature setting. The heat distribution state of the heat source represents the uniformity of the heat distribution in the car. The cooling intensity of the air-conditioning is adjusted according to the unevenness of the heat distribution state of the heat source. Targeted temperature adjustment is performed according to the actual situation of heat distribution to improve the efficiency of temperature control. It can also respond promptly to changes in the actual thermal environment to achieve more precise temperature control.

[0125] In a feasible implementation, step C12 may include steps D11 to D12:

[0126] Step D11, obtaining a target heat distribution photo;

[0127] It should be noted that the target heat distribution photo reflects the characteristics of the heat energy distribution state generated by the passengers and objects in the vehicle due to sunlight.

[0128] It can be understood that the target heat distribution photo shows the heat distribution actually felt by the occupants, thereby intelligently adjusting the wind direction, temperature and wind speed of the air-conditioning outlet to achieve more precise and personalized temperature control, improve the comfort of the occupants, and adjust the air-conditioning output according to actual needs to avoid unnecessary energy consumption.

[0129] Step D12: obtaining the air conditioning cooling state and the heat source heat distribution state based on the heat distribution photo and the target heat distribution photo.

[0130] It is understandable that the standard human body thermal imaging distribution is usually symmetrical. Sun exposure will cause uneven heat distribution, and the heat in the sun-exposed area will be significantly higher than in other areas. The heat distribution photo is compared with the target heat distribution photo. The air conditioning air outlet strategy is stopped when the heat source heat distribution is balanced. The effect of the air conditioning adjustment strategy is tracked and evaluated to determine the air conditioning cooling status and the heat source heat distribution status, and then adjust the air conditioning air outlet strategy to ensure that the occupants feel comfortable in the direct sunlight area and avoid the discomfort of overheating or overcooling.

[0131] In addition, it should be noted that if there are exogenous heat sources, such as mobile phones and small animals, the heat source map will be unevenly distributed. If the area of ​​the human body exposed to sunlight does not coincide with the abnormal heat source, the air conditioning outlet strategy will not be executed. If the area of ​​the human body exposed to sunlight coincides with the abnormal heat source, the air conditioning outlet strategy will be executed until the preset threshold is reached and then stopped. At this time, if the heat source map is still different from the standard heat source map under the condition of symmetrical distribution, the air conditioning outlet strategy delay will be adjusted to linearly decrease until it is executed according to the conventional air conditioning strategy.

[0132] Step C13: Controlling air conditioning cooling based on the heat distribution state of the heat source and the air conditioning cooling state.

[0133] It can be understood that based on the heat distribution state of the heat source and the cooling state of the air conditioner, adjustments are made according to the preset air conditioning strategy, including enhancing the cooling effect, weakening the cooling effect and stopping the air conditioning, and fine-tuning is made according to actual needs without relying on the preset program for adjustment, so as to quickly respond to changes in the external environment.

[0134] In a feasible implementation, step C13 may include steps E11 to E13:

[0135] Step E11, when the heat source heat distribution state is uneven and the air conditioner cooling state is insufficient cooling effect, controlling the air conditioner to lower the temperature, increase the air volume, extend the blowing time, and adjust the sweeping path;

[0136] It is understandable that when the air-conditioning system detects that the heat distribution of the heat source is uneven and the cooling effect of the air-conditioning is insufficient, it enhances the cooling effect of the air-conditioning by lowering the temperature, increasing the air volume, extending the blowing time and adjusting the wind sweeping path, so as to achieve the best comfort and energy efficiency ratio and reduce the discomfort caused by direct sunlight in hot summer or under long periods of sunshine.

[0137] Step E12: When the heat source heat distribution state is uneven and the air conditioner cooling state is excessive cooling effect, controlling the air conditioner to increase the temperature, reduce the air volume, shorten the blowing time, and adjust the sweeping path;

[0138] It is understandable that when the air-conditioning system detects that the heat distribution state of the heat source is uneven and the cooling state of the air-conditioning is excessive, it reduces the cooling effect of the air-conditioning by increasing the temperature, reducing the air volume, reducing the blowing time and adjusting the wind sweeping path, so as to achieve the best comfort and energy efficiency ratio, provide a more personalized comfort experience, and adjust the temperature in time before the human body feels cold.

[0139] Step E13: When the heat distribution state of the heat source is balanced, the air conditioner is controlled to stop cooling.

[0140] It is understandable that when the heat distribution in the car has reached a uniform state, that is, there are no obvious hot spots or cold spots, it indicates that the current temperature is appropriate, and the air-conditioning system will stop the cooling operation to maintain the temperature in the car, while avoiding unnecessary energy waste, improving energy efficiency, and avoiding temperature differences caused by excessive cooling, thereby providing a stable and comfortable environment.

[0141] The air conditioning control method based on light tracking and human body recognition proposed in this embodiment obtains the perceived heat of the target illuminated area; determines the air conditioning cooling state based on the perceived heat of the illuminated area and the perceived heat of the target illuminated area; and adjusts the air direction, temperature, and wind speed of the air conditioning outlet based on the air conditioning cooling state. This solves the technical problem of how to accurately adjust the air outlet of the air conditioner. Compared with the existing technology, this application accurately obtains the heat distribution generated by direct sunlight in the car, that is, the perceived heat of the target illuminated area, and compares it with the preset perceived heat of the target illuminated area. It intelligently adjusts the air outlet direction, temperature, and wind speed of the automobile air conditioning system to ensure uniform temperature distribution in the car, meet the personalized comfort needs of passengers, and significantly improve the riding experience. Even in hot summer or under long periods of sunshine, passengers can enjoy a cool and comfortable car environment. At the same time, by accurately controlling the air outlet of the air conditioner, energy efficiency is improved and unnecessary energy consumption is reduced.
