Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a method for adjusting comfort and a related device. Background Art

[0002] The user's comfort level is affected by various factors. In order to provide users with a more comfortable experience, the comfort level is generally adjusted through adjustment devices, for example, a temperature adjustment device is used to adjust the temperature, and a wind speed adjustment device is used to adjust the wind speed.

[0003] Adjustment equipment can quickly adjust the comfort level in a space. However, the adjustment equipment generally automatically adjusts the comfort level according to a functional mode preset by the user, which cannot meet the actual needs of the user. Summary of the invention

[0004] The present application provides a comfort adjustment method and related devices, which can improve the user's comfort experience.

[0005] In a first aspect, the present application provides a method for adjusting comfort, which can be applied in the field of electronic technology, and the method comprises:

[0007] Compared to automatically adjusting the comfort level according to the user's preset function mode, the present application adjusts the comfort level by combining environmental information, user information and thermal comfort characterization indicators, thereby achieving adaptive adjustment of the comfort level, eliminating the trouble of manual operation by the user, and further improving the user experience. In addition, compared to adjusting the comfort level using a single device, the present embodiment can jointly adjust multiple devices based on environmental information, user information and thermal comfort characterization indicators, thereby further improving the response speed of comfort adjustment, achieving a more rapid comfort effect, and improving unit energy efficiency, saving energy consumption.

[0120] (4) Receivers, terminals, intelligent terminals, wireless devices, handheld devices, mobile units, vehicle-mounted devices, artificial intelligence devices, machine equipment, household equipment, medical equipment, industrial equipment, etc.;

[0121] (5)Others

[0122] Those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific working process of the device described above can refer to the corresponding process in the aforementioned method embodiment, and will not be repeated here.

[0123] Understandably, Figure 1a and Figure 1b The structure of the adjustment system shown is only an example. The comfort adjustment method provided in the embodiment of the present application can be applied to the structure described above but is not limited to it, and is not limited here.

[0124] The comfort adjustment method provided in the embodiment of the present application can be applied to non-open spaces such as houses, cars, cabins (such as sleeping cabins, submarines, etc.), and any scenario in which the comfort is adjusted in combination with the environment and the user. The space can be a local space, in which devices with different functions are arranged, and the comfort can be jointly adjusted by adjusting different parameters between the devices. The devices can be connected via wired or wireless connections. Alternatively, devices with different functions can also be a device that integrates multiple functions.

[0125] Example Scenario 1: In-car Scenario

[0126] In this scenario, the user is driving or resting in the car, and the thermal environment information in the car, the user's thermal preference differences and metabolic rate, etc. will affect the user's comfort experience in the car. The comfort adjustment method provided in the embodiment of the present application can adjust the comfort by controlling the air conditioner, seat, window glass, etc. For example, by adjusting the wind speed and air volume of the air conditioner, the angle and surface temperature of the seat, the radiation transmittance of the window glass, and the thermal preference differences and metabolic rate of the human body, the comfort in the car is adjusted to meet the user's comfort needs.

[0127] Example Scenario 2: Sleeping Scenario

[0128] In this scenario, the user is preparing to rest for a period of time. The user may have different requirements for the thermal environment at different stages of sleep. The thermal environment information in the space, the user's thermal preference differences during sleep, and the metabolic rate will all affect the user's comfort experience during sleep. The comfort adjustment method provided in the embodiment of the present application can adjust the comfort by controlling the air conditioner, fan, etc. to meet the user's comfort needs.

[0129] The comfort adjustment method provided in the embodiment of the present application can be applied to the adjustment system, and is executed by the control device of the adjustment system to control multiple devices to adjust the comfort in the space. The control device in the adjustment system and each device, and each device can jointly control the devices in the space in a wireless or wired manner to adjust the user comfort in the space.

[0130] At present, the mainstream comfort adjustment method generally adopts a preset automatic adjustment mode, such as the user customizes the temperature and duration in the car through the control system to keep the temperature in the car constant; or, the temperature in the car is automatically adjusted by the control system in the car to keep the room temperature constant; or, by monitoring the temperature at a specific time point, the indoor temperature is adjusted, such as automatically raising (when cooling) or lowering (when heating) the air-conditioning temperature after the nap mode is turned on for 0.5 hours, or the air-conditioning temperature rises by 2°C and remains unchanged (when cooling) or decreases by 2°C and remains unchanged (when heating) within 2 hours.

[0131] However, using the preset automatic adjustment mode to adjust the comfort level in the space will have the following problems:

[0132] (1) The wind speed and direction when the automatic air conditioner is turned on may not be suitable for a specific scene. For example, in the sleeping scene, the user is likely to feel a noticeable draft in a closed environment and be easily woken up by the draft. In addition, excessive wind speed will produce noise, affecting the sleep quality.

[0133] (2) Setting the temperature to a constant value cannot fully meet the thermal comfort needs of the human body during sleep and does not take into account the changes in the human body's demand for the thermal environment during sleep;

[0134] (3) The impact of changes in external environmental radiation is not taken into account. For example, in a car interior, the car body is also greatly affected by changes in the external environment compared to the interior of the car. Current technologies often ignore the impact of the external environment, resulting in unintelligent adjustments.

[0135] In order to solve the above problems, the present application embodiment provides a method for adjusting comfort, which can be applied to the adjustment system described in the above scenario. Figure 1c , Figure 1c A flow chart of a method for adjusting comfort provided in an embodiment of the present application. The method specifically comprises: S1. Acquiring environmental information and user information corresponding to a first space; the first space is a non-open space. S2. Determining a control index of at least one device corresponding to the first space based on the environmental information, the user information and a characterization index of thermal comfort. S3. Controlling the at least one device based on the control index of the at least one device.

[0136] It can be understood that, on the first hand, compared to automatically adjusting the comfort level according to the user's preset functional mode, the present application adjusts the comfort level by combining environmental information, user information and the characterization index of thermal comfort, thereby realizing adaptive adjustment of the comfort level, eliminating the trouble of manual operation by the user, and further improving the user experience. On the second hand, compared to adjusting the comfort level by a single device, the present embodiment can jointly adjust multiple devices based on environmental information, user information and the characterization index of thermal comfort, thereby further improving the response speed of comfort adjustment, achieving a more rapid comfort effect, and improving the unit energy efficiency, saving energy consumption.

[0137] The above introduces the application scenarios of the comfort adjustment method provided in the embodiments of the present application. The following will introduce in detail the implementation process of the comfort adjustment method provided in the embodiments of the present application.

[0138] First of all, in order to better understand the solutions of the embodiments of the present application, the relevant terms and concepts that may be involved in the embodiments of the present application are introduced below.

[0139] (1) Average thermal sensation index

[0140] The Predicted Mean Vote (PMV) is an evaluation index that reflects the human body's perception of heat and cold, and represents people's average perception of heat and cold in the same environment. For example, PMV can be divided into 7 comfort evaluation levels, namely -3 (cold), -2 (cool), -1 (slightly cool), 0 (comfortable), +1 (slightly warm), +2 (warm), and +3 (hot).

[0141] (2) Expected dissatisfaction percentage

[0142] The predicted percentage dissatisfied (PPD) indicates the percentage of people who are dissatisfied with the thermal environment, that is, the percentage of the population who are dissatisfied with the thermal environment.

[0143] See also Figure 2 , Figure 2 Another flowchart of the comfort adjustment method provided in the embodiment of the present application. The comfort adjustment method can be executed by the control device of the adjustment system. Figure 2 As shown, the control device can improve the user's comfort experience by executing the following steps 201 to 205.

[0144] Step 201: A control device obtains environment information and user information corresponding to a first space.

[0145] In the embodiment of the present application, the first space mainly refers to the non-open space as exemplified above. Environmental information mainly refers to the current environment and relevant parameter information of the equipment. Among them, the equipment mainly refers to the relevant equipment for adjusting parameters. For example, equipment such as air conditioners or fans for adjusting air volume, wind speed, wind direction, and air temperature, humidity control equipment for adjusting relative humidity, etc. Corresponding to different application scenarios, for example, in a car, the equipment may include a car air conditioner, a fan, a seat (which can be used to adjust the temperature of the seat surface), a car window glass (which can be used to adjust the transmittance of sunlight), etc. In an optional implementation method, the environmental information includes at least one of air temperature, relative humidity, average radiant temperature, wind speed, wind volume, wind direction, noise, and surface temperature of the equipment.

[0146] In this implementation, air temperature mainly refers to the air temperature inside and outside the space and around the user. It should be understood that the comfort adjustment method provided in the embodiment of the present application is mainly to improve the user's comfort experience. Therefore, it is necessary to consider the temperature, humidity, average radiation temperature, wind speed, wind volume, wind direction, noise, etc. around the user. Wind speed mainly refers to the change in wind speed around the human body. Radiation mainly refers to the sunlight radiation and net long-wave radiation received by the human body, which can be characterized by the average radiation temperature.

[0147] It is understandable that, in actual application, the specific content of the environmental information can be set according to actual needs or experiments. For example, it can also include the direction of the fan blades, etc., which is not limited here.

[0148] In an optional implementation, the user information includes: user behavior information and user thermal comfort information.

[0149] User behavior information includes the stage of the user's behavior activity;

[0150] The user's thermal comfort information includes at least one of the following: the user's clothing, bedding or other body surface covering information, physiological indicators, metabolic rate, age or comfort preference.

[0151] In this implementation, the user's behavior information mainly includes the stage of the user's behavior activity. For the user, the user may have different needs and preferences at different stages of the behavior activity. The control device adjusts the comfort based on the user's behavior information, which helps to improve the user's comfort experience. The user's thermal comfort information mainly refers to information related to the user's thermal sensation.

[0152] The user's behavior and the stage of the behavior can be obtained based on the data set by the user or one or more devices such as wearable devices, cameras, sensors, etc. This includes, for example, the start time and duration of the sleep mode set by the user, the time and duration of the user's sleep determined by the wearable device, the closing of eyes and other actions monitored by the camera, the breathing rate monitored by the microphone, and the pressure sensor detecting the user's pulse, breathing, body movements, staying in bed, etc. to determine the stage of the user's nap.

[0153] It is understandable that the control device can adjust the comfort level in combination with the user's behavior information and the user's thermal comfort information. Among them, the user's comfort preference can be obtained based on the user's pre-set parameters and / or the current environmental parameters, or based on historical data. The user's comfort preference is divided into subjective preference and objective preference. Subjective preference mainly refers to the user's own requirements for comfort, for example, the user is more comfortable at a certain temperature or wind speed. Objective preference mainly refers to relevant information that can improve the user's comfort experience faster or more effectively based on actual experiments or theoretical data.

[0154] Optionally, the user's behavioral activity is taking a nap.

[0155] The user's behavior activities include different stages. For example, assuming that the user is taking a nap, the user may be in one of the three stages: before falling asleep, falling asleep, and the end of sleep / about to wake up.

[0156] Optionally, the at least two stages of the behavioral activity include: at least two of: before falling asleep, during sleep, and at the end of sleep. It should be understood that the user's thermal comfort information and environmental information may be different in different behavioral stages. Taking the sleep scene as an example, the wind speed around the human body before and after falling asleep, the sunlight radiation and net long-wave radiation received by the human body before and after falling asleep, the changes in the human body's metabolic rate before, after and during sleep, and the thermal resistance information of clothing and bedding before and after falling asleep may all be different. The embodiments of the present application are for illustrative purposes only and are not limiting.

[0157] Step 202: The control device adjusts the comfort index according to the user information to obtain an adjusted comfort index.

[0158] In the embodiment of the present application, after obtaining the initial comfort characterization index, the control device can adjust the comfort characterization index based on the user information to meet the user's comfort requirements for different stages of behavioral activities and different scenarios. Among them, the comfort characterization index is mainly used to represent the user's evaluation index of comfort. Since the user has different requirements for comfort at different stages of behavioral activities, the control device mainly adjusts the comfort characterization index based on the user's behavioral information.

[0159] Compared to adjusting the comfort level based on comfort characterization indicators directly set by the user or by default, or only based on comfort characterization indicators at individual time points of different behavioral activities of the user, the embodiment of the present application adjusts the comfort characterization indicators in stages based on the stages of different behavioral activities of the user, and matches them with the actual thermal needs of the user, thereby further improving the user's comfort experience.

[0160] In an optional implementation, the control device may obtain a characterization index of comfort based on historical data and experimental results.

[0161] The control device may obtain a general setting value of the characterization index of comfort based on historical experience data, experimental data or theoretical literature, etc. Optionally, the control device may also set a corresponding change curve based on the characterization index of comfort corresponding to different stages, so as to set the corresponding characterization index of comfort for different stages.

[0162] In an optional implementation, the comfort indicator includes PMV.

[0163] In this implementation, taking sleeping behavior as an example, the comfort index can be determined by the different stages of the user's nap, wherein the different stages of the user's nap can be determined based on the start and end times and duration of sleep set by the user, the state of falling asleep, and behaviors such as staying in bed.

[0164] The PMV value may be different in different stages of sleep. Figure 3 , Figure 3 The distribution curve diagram of the PMV value of the user during sleep provided in the embodiment of the present application. The PMV value can be set according to the following reasons.

[0165] (1) Stage 1 (before falling asleep): A relatively warm environment within the thermal comfort range, which reduces the skin temperature difference between the distal and proximal ends of the user and promotes falling asleep (taking PMV as an example, PMV = 0.5);

[0166] (2) Stage 2 (falling asleep): Maintain thermal comfort, and the quality of sleep is higher in a thermally neutral environment (taking PMV as an example, PMV = 0);

[0167] (3) The third stage (late sleep / about to wake up): a cooler environment within the thermal comfort range, which reduces the probability of sleep inertia (taking PMV as an example, PMV = -0.5).

[0168] The user manually turns on the nap mode, which is the starting point of the first stage (before falling asleep); or the device can determine the starting point, such as when the user lies down, closes his eyes, or changes from dynamic to static. The end point of the first stage is when the user is determined to be asleep, such as by capturing the user's behavior through a camera or other device to determine that the user has fallen asleep.

[0169] The starting point of the second stage (falling asleep) is the end point of the first stage. The end point of the second stage can be determined according to the end point of the nap mode. For example, if the end point of the nap is 3 pm, the end point of the second stage is a fixed time in advance of the end point of the nap (for example, 5 minutes in advance). The end point of the nap mode can be set manually by the user. The end point of the second stage can also be determined based on the user status. For example, if the user wakes up early, the nap mode ends early and there is no need to enter the third stage.

[0170] The third stage (the end of sleep) ends at the nap end by default. The end of the third stage can also be determined based on the user's status. For example, if the user turns off the alarm and continues to sleep, the end of the third stage is adjusted to extend the third stage.

[0171] In actual application, currently, the comfort is generally adjusted according to the default value of PMV, and the comfort cannot be dynamically adjusted in combination with the actual needs of the user and the environment, resulting in a poor user comfort experience. In this embodiment, the control device can adjust the value of PMV according to the stage of the user's behavior activity to more accurately match the user's comfort needs.

[0172] In addition, the stage of the user's behavioral activity can be adjusted according to actual conditions, and does not change in a specified time sequence. The control device can adjust the stage of the user's behavioral activity according to actual needs, so as to determine a more accurate PMV target value. For example, assuming that the user is in the third stage, the user turns off the alarm and continues to sleep for 10 minutes. In order to ensure the user's sleep quality, the control device can set the user's nap stage to the second stage in the first 5 minutes of the set 10 minutes. Correspondingly, the control device sets the PMV target value to the value corresponding to the second stage. In the next 5 minutes, in order to enable the user to overcome sleep inertia, the control device can set the PMV target value to the value corresponding to the third stage to reduce the user's sleep inertia.

[0173] It is understandable that the value of PMV can also be set based on the user's customized hot and cold preferences. If the user frequently adjusts the temperature manually over a period of time, the control device can also collect relevant user data and adapt historical operations to meet the user's preferences. In addition, the values ​​of PMV at different stages are not only related to the user's thermal preferences, usage habits, etc., but may also be related to the user's population type, such as the elderly, children, pregnant women, and patients with diseases. The specific settings can be based on actual needs.

[0174] Optionally, comfort indexes may also include equivalent homogeneous temperature (EHT), dynamic thermal sensation index (DTS), thermal perception index, etc., which are not limited here.

[0175] It is understandable that the control device can select corresponding comfort characterization indicators according to different scenarios and requirements.

[0176] Step 203: The control device determines a functional relationship of a control index of at least one device corresponding to the first space according to the environmental information, the user information and the adjusted characterization index of the comfort level.

[0177] In the embodiment of the present application, the functional relationship of the control index of at least one device corresponding to the first space mainly refers to the functional relationship between the target values ​​or target ranges of the control index corresponding to each of the at least one device.

[0178] The specific composition of each device and the target value or target range of the control index corresponding to each device can be determined based on the environmental information and user information. For example, assuming that the environmental information includes wind speed, relative humidity, and seat surface temperature, the control device can control the air conditioner or fan, humidity control device, and seat heating device to adjust the wind speed, relative humidity, and seat surface temperature to the target value or target range that satisfies the comfort level, based on the user's behavior information at different stages, the user's comfort requirements, and other constraints. In the above example, the device may include an air conditioner or fan, and a humidity control device, and the control index to be adjusted corresponding to each device may include the target value of the wind speed adjusted by the air conditioner or fan, the target value of the relative humidity adjusted by the humidity control device, and the target value of the seat surface temperature adjusted by the seat heating device.

[0179] In addition, at a certain moment, the control device can obtain the functional relationship between the target values ​​of the control indicators corresponding to at least one device at that moment according to the parameter information corresponding to that moment. Within a certain time period, the control device can obtain the functional relationship between the target values ​​of the control indicators corresponding to at least one device within that period according to the average parameter information within that period.

[0180] It is understandable that, in actual applications, each device and its corresponding control indicators can be set according to actual needs or tests. In different application scenarios and under different needs, the types of devices and control indicators are somewhat different. The embodiments of this application are only provided for illustrative purposes and are not limited thereto.

[0181] In an optional implementation, the at least one device includes at least two devices;

[0182] The control device determines the control index of at least one device corresponding to the first space according to the environmental information, the user information and the characterization index of the thermal comfort, including:

[0183] According to the environmental information, the user information and the characterization index of thermal comfort, a functional relationship between control indexes of at least two devices corresponding to the first space is determined.

[0184] In this implementation, the control device jointly adjusts multiple devices based on environmental information, user information and thermal comfort characterization indicators, thereby further improving the response speed of comfort adjustment and achieving a comfortable effect more quickly.

[0185] In an optional implementation, the control device inputs environmental information, user information and an adjusted thermal comfort index into a first model to determine a control index of at least one device corresponding to the first space.

[0186] In this implementation, the control device may input environmental information, user information, and an adjusted thermal comfort index into a pre-set first model to determine a control index of at least one device corresponding to the first space.

[0187] In actual applications, if the control device wants to add a new device to jointly adjust the comfort with other devices, in some cases, the control device may also need to add calculation items about the device in the first model, so as to perform joint calculations in combination with the parameter indicators of other devices included in the first model, and obtain the functional relationship between the control indicators corresponding to each device.

[0188] It should be understood that when calculating the control index of a single device based on the first model, since the unknown quantity is unique, the first model outputs the control index of the single device. When calculating the control index corresponding to each of multiple devices based on the first model, since the calculation items of the specified device are added in the first model, there are multiple unknown quantities and it is impossible to obtain a unique solution. Therefore, the first model outputs the functional relationship based on the control index corresponding to each of the multiple devices. For example, in order to avoid the feeling of blowing and noise, in addition to controlling the air conditioner, if the control device determines that seat heating is needed to adjust the comfort level in conjunction with the air conditioner based on the internal and external environmental information and device information, the control device can measure the size and temperature of the current seat surface in contact with the human body, and add a conductive heat item (corresponding to the calculation item of the seat surface temperature) in the first model based on the measured parameters, so that after the control device inputs the environmental information, user information, the adjusted comfort characterization index and the current temperature of the seat surface into the first model, the functional relationship between the target value of the air temperature under the comfort condition and the target value of the seat surface temperature is output.

[0189] In an optional implementation, the control device may obtain environmental parameters inside and outside the vehicle and device information inside the vehicle to determine the devices involved in comfort adjustment.

[0190] In this implementation, optionally, the first model includes a PMV-PPD thermal comfort model.

[0191] Optionally, the first model includes an EHT equivalent temperature model, a Fiala DTS thermal comfort model, etc.

[0192] For example, taking the first model as the PMV-PPD thermal comfort model, and adding a conductive heat term to the first model, the formula of the first model is:

[0193] PMV=(0.303e -0.036M +0.0275)L=(0.303e -0.036M +0.0275)*(MWCRE)

[0194] Among them, L is the heat load, M is metabolic heat production, W is external work, C is convective heat transfer, R is radiation heat transfer, and E is evaporative respiration heat transfer.

[0195] A heat conduction term related to the seat surface temperature is added to the first model. The formula of the first model is:

[0196] PMV=(0.303e -0.036M +0.0275)L=(0.303*e -0.036M +0.0275)*(MWCREQ)

[0197] Wherein, L is the heat load, Q is the conduction heat transfer term, and is a function of the seat surface temperature T and the temperature difference ΔT between the skin and the seat surface, where the skin refers to the skin of the user in contact with the seat surface.

[0198] Optionally, Q can be expressed as:

[0199]

[0200] Where S is the seat contact area fraction, I cl is the thermal resistance of clothing.

[0201] It should be noted that the above formula is only an example. The specific content of the formula and the content of the newly added calculation items can be set according to actual needs and are not limited here.

[0202] Step 204: The control device obtains a control index corresponding to at least one device according to the functional relationship.

[0203] In an embodiment of the present application, after the control device determines the functional relationship of the control index of at least one device corresponding to the first space by combining environmental information, user information and the characterization index of the user's comfort at different stages, it can further calculate the control index corresponding to at least one device.

[0204] Among them, the control index corresponding to at least one device refers to the target value or target range of the control index corresponding to at least one device. Since the adjustment of comfort needs to be combined with the current actual environmental requirements, user requirements and other information, therefore, in actual application, if any set of solution values ​​in the functional relationship between the control indicators corresponding to at least one device meets the requirements, multiple sets of parameter values ​​that meet the requirements can be directly determined from the functional relationship according to the actual situation.

[0205] Optionally, the control device obtains a control index corresponding to at least one device according to the first constraint and the functional relationship.

[0206] It can be understood that the first constraint refers to constraint information corresponding to the actual environment and user needs. If certain constraint conditions exist, the control device can limit the value range of the control index corresponding to at least one of the multiple devices in combination with the first constraint condition, thereby further obtaining a result that satisfies the condition from the functional relationship between the control indexes corresponding to the at least one device.

[0207] In an optional implementation, the first constraint includes at least one of an environment constraint, a user constraint, a device constraint, and an energy consumption constraint.

[0208] In this implementation, the control device may select a control indicator that meets the requirement from the functional relationship between the control indicators corresponding to at least one device in combination with the first constraint.

[0209] Among them, the first constraint includes constraints of multiple dimensions, and the environmental constraint may include indicators such as temperature and humidity inside and outside the space and around the human body. For example, in order to avoid the feeling of blowing, the blowing index can be calculated based on environmental information such as temperature and wind speed distribution. If the blowing index exceeds the threshold, the wind speed is reduced to below the threshold, and the new wind speed value is substituted into the first model. For example, if the temperature difference between inside and outside is too large, the air conditioner needs to open a larger wind gear (also a device constraint) to ensure that the space can be cooled / heated to a comfortable target temperature in time, but it will cause problems such as excessive wind noise and obvious blowing, and other equipment such as seat ventilation / heating are required to cooperate; or for example, the noise in the car should not exceed 35dB, and the relative humidity should not be higher than 65%. User constraints may include user preferences, for example: different users have different needs or preferences for blowing, relative humidity (for example, asthma patients have requirements for relative humidity), sunlight radiation tolerance, etc. Equipment constraints may include equipment noise level, wind direction level, etc. For example, in order to avoid air conditioning noise, the control device can determine the noise level according to the wind gear. If the noise exceeds the threshold, the wind speed is reduced to below the threshold and the new wind speed value is substituted into the first model. For example, whether the current device is available, the response of the device in the current vehicle interior and exterior environment (whether it will generate noise and excessive wind blowing), etc. Energy consumption constraints are mainly considered from the perspective of energy consumption, and corresponding constraints can be set according to actual energy consumption requirements.

[0210] In an optional implementation, the at least one device includes at least two devices;

[0211] The control device determines the control index of each of the at least two devices according to the functional relationship between the control indexes of the at least two devices corresponding to the first space.

[0212] In this implementation method, after the control device determines the functional relationship between the control indicators of at least two devices corresponding to the first space by combining environmental information, user information and the characterization indicators of the user's comfort at different stages, it can further calculate the control indicators corresponding to the at least two devices.

[0213] In this implementation, optionally, the control device determines the control index of each of the at least two devices according to the functional relationship between the first constraint and the control indexes of the at least two devices corresponding to the first space.

[0214] It is understandable that in actual applications, assuming that the control device jointly controls three devices to adjust the comfort, the control device generally determines the target value ranges of the parameters of two of the devices based on the first constraint, and then determines the target value ranges of the remaining device parameters based on the functional relationship.

[0215] Step 205: The control device controls at least one device according to the control indicator of the at least one device.

[0216] In the embodiment of the present application, after determining the control index of at least one device, the control device can control at least one device according to the control index. For example, the control device adjusts the air conditioner according to the change in the set temperature of the air conditioner, adjusts the seat according to the temperature of the seat surface, the heating gear and time, and adjusts the seat according to the ventilation gear of the seat.

[0217] In an optional implementation, the control index of at least one device includes at least one of the following: air temperature, relative humidity, wind speed, wind direction, device surface temperature or glass transmittance.

[0218] In this implementation, the control index of at least one device may include multiple parameters, and different parameters may correspond to different devices. For example, after determining the control index of at least one device, the control device may control air conditioners and other devices according to the air temperature, may control humidity control devices according to relative humidity, may control air conditioners or electric fans and other devices according to wind speed and wind direction, may adjust seats and other devices according to the surface temperature of the device, and may adjust glass and other devices according to the refractive index of the glass. In addition, the surface temperature of the device includes not only the surface temperature of the seat, but also the surface temperature of other devices with heat radiation functions, such as infrared heat radiators (such as electric heaters, etc.).

[0219] In an optional implementation, the at least one device includes at least two devices;

[0220] The control device controls at least two devices respectively according to respective control indicators of the at least two devices.

[0221] In this implementation, the control device can control at least two devices separately according to the control indicators of the at least two devices, so as to jointly adjust the user's comfort based on multiple devices, further improve the adjustment efficiency, and save energy consumption to a certain extent.

[0222] In order to more clearly understand the comfort adjustment method provided in the embodiment of the present application, it is introduced below with reference to specific examples.

[0223] Example scenario 1

[0224] At lower temperatures, only air conditioning is used to regulate the thermal comfort of a closed environment. Assuming that the temperature is -15℃ on a winter day, in a basement without sunlight radiation and heating, a person wearing winter clothes gets on the car, takes off his coat, and then puts on indoor winter clothes (1clo) for a 45-minute nap. The initial temperature inside the car is similar to the temperature outside the car.

[0225] In this scenario, since the temperature inside and outside the car is low, if the temperature is only raised by air conditioning, it may result in long heating time, too high air speed of the air conditioner, excessive noise and high energy consumption. In order to avoid the problem of blowing wind, noise, duration and energy consumption, the heating of the seat surface can be controlled to quickly achieve the heating of the car to meet the user's heating needs.

[0226] In this regard, the embodiment of the present application provides a method for adjusting comfort, which is mainly performed by a control device in the adjustment system. Figure 4 , Figure 4 Another flowchart of the comfort adjustment method provided in the embodiment of the present application is shown below. Figure 4 As shown, it mainly includes steps 401 to 407.

[0227] Step 401: The control device obtains the environment information and user information in the vehicle.

[0228] Among them, environmental information includes information such as the air temperature inside the car, wind speed around people, relative humidity, sunlight radiation, temperature and size of the seat surface, etc.

[0229] Step 402: The control device adjusts the target value of the PMV according to the user information.

[0230] Optionally, the control device may adjust the target value of the PMV according to the user's behavior information, for example, the stage of the user's behavior activity.

[0231] Optionally, the user information includes historical user usage data (for example, air conditioning temperature for thermal comfort, equipment parameters during past sleep under similar working conditions, etc.), human metabolic rate, thermal resistance of clothing or mattresses, and other information.

[0232] Step 403: The control device determines the device to be adjusted according to the environmental information.

[0233] In this embodiment, the control device can combine the temperature information and other constraint information of the device to add a seat to adjust the comfort.

[0234] It is understandable that due to the low temperature inside and outside the car, if the temperature is only raised by air conditioning, it may lead to long heating time, too high air speed of air conditioning, too much noise and too high energy consumption. In order to avoid the problem of blowing wind, noise, duration and energy consumption, the heating of the seat surface can be controlled to quickly achieve the heating of the car to meet the heating needs of users.

[0235] There is no requirement for the execution order of step 402 and step 403.

[0236] Step 404 : The control device adds a conduction heat item corresponding to the temperature of the seat surface in the PMV-PPD thermal comfort model in combination with the environmental information.

[0237] Among them, step 404 is an optional step. The control device can add a conductive heat item corresponding to the temperature of the calculated seat surface in the PMV-PPD thermal comfort model in advance according to the environmental information. After obtaining information such as the temperature and size of the seat surface, the above information is directly input into the PMV-PPD thermal comfort model with the added conductive heat item, and the functional relationship between the air temperature and the seat surface temperature that meets the thermal comfort target in different sleep stages is output. Alternatively, the control device can also add a conductive heat item corresponding to the temperature of the calculated seat surface in the PMV-PPD thermal comfort model in combination with the current environmental information, and then perform the next step of calculation.

[0238] In step 405, the control device brings the environmental information and the user information into the PMV-PPD thermal comfort model to obtain a functional relationship between the air temperature and the seat surface temperature that meets the thermal comfort target in different sleep stages.

[0239] Step 406 : The control device obtains control indicators corresponding to the air conditioner and the seat respectively according to the constraint conditions and the functional relationship between the air temperature and the seat surface temperature.

[0240] In this step, the control device can set a lower target air temperature (such as 20°C) that makes the wind speed moderate in combination with equipment design principles and energy consumption constraints, and then output the target seat human body contact surface temperature range (30-36°C) based on the functional relationship according to the determined target air temperature range, and turn on the seat heating to switch to the insulation mode after reaching the target temperature range.

[0241] Step 407 : The control device adjusts the air conditioner and the seat respectively according to the control indicators corresponding to the air conditioner and the seat.

[0242] Example Scenario 2

[0243] Thermal comfort is regulated in a closed environment with high relative humidity. Assume that the ambient temperature is 28°C on a rainy day, and the user takes a 45-minute nap in the environment wearing summer clothes. The initial temperature and relative humidity in the environment are equivalent to those of the outside environment.

[0244] In this scenario, due to the high relative humidity in the environment, in addition to adjusting the temperature, it is also necessary to use humidity control equipment to adjust the relative humidity to solve the problem of excessive relative humidity, thereby further improving the user's comfort experience.

[0245] In this regard, the embodiment of the present application provides a method for adjusting comfort, which is mainly performed by a control device in the adjustment system. Figure 5 , Figure 5 Another flowchart of the comfort adjustment method provided in the embodiment of the present application is shown below. Figure 5 The above mainly includes steps 501 to 507.

[0246] Step 501: Control the device to obtain environment information and user information.

[0247] Environmental information includes air temperature, wind speed around people, relative humidity, etc. User information includes historical user usage data (for example, air conditioning temperature when thermally comfortable, equipment parameters during previous sleep under similar working conditions, etc.), human metabolic rate, thermal resistance of clothing or mattresses, etc.

[0248] It is understandable that the thermal resistance information of the user's clothing or mattress will affect the air temperature of the user during sleep.

[0249] For example, see Figure 6a , Figure 6a A schematic diagram of the change in air temperature at different sleep stages when a user is wearing summer clothes provided in an embodiment of the present application. Assuming that the user is wearing summer clothes and the air temperature before falling asleep is T, the user's metabolic heat generation decreases during the user's sleep. In order to ensure the user's thermal comfort needs and prevent the user from catching a cold, the temperature T may continue to rise. At the end of sleep, in order to reduce the user's sleep inertia, the temperature can be lowered to help the user wake up as soon as possible and avoid sleep inertia.

[0250] See also Figure 6b , Figure 6b A schematic diagram of the change in air temperature at different sleep stages when the user covers the quilt provided in the embodiment of the present application. Assuming that the user covers the quilt with a thickness of 0.5clo and the air temperature before falling asleep is T, during the user's sleep, in order to ensure the user's thermal comfort needs and prevent the user from feeling too hot due to reduced heat dissipation after covering the quilt, the temperature T may drop (the change is 0.5°C). At the end of the sleep stage, in order to reduce the user's sleep inertia, the temperature can be further lowered (the change is 1°C) to help the user wake up as soon as possible.

[0251] Step 502: The control device adjusts the target value of the PMV according to the user information.

[0252] Step 503: The control device determines the device to be adjusted according to the environmental information.

[0253] Among them, the control device can combine the temperature information, humidity information and other constraint information of the device, and add a humidity adjustment device to adjust the comfort level.

[0254] It is understandable that, due to the high relative humidity in the environment, in addition to adjusting the temperature, it is also necessary to use humidity adjustment equipment to adjust the relative humidity in order to solve the problem of excessive relative humidity.

[0255] There is no requirement for the execution order of step 502 and step 503.

[0256] Step 504: The control device selects the PMV-PPD thermal comfort model based on environmental information.

[0257] In this step, since the first model includes parameters of relative humidity, the control device does not need to add additional parameters and calculation items related to relative humidity. The control device selects the PMV-PPD thermal comfort model for calculation according to environmental information.

[0258] Step 505 , the control device brings the environmental information and user information into the PMV-PPD thermal comfort model to obtain the functional relationship between the air temperature, wind speed, and relative humidity that meet the thermal comfort target in different sleep stages.

[0259] Step 506: The control device obtains control indicators corresponding to the air temperature, wind speed, and relative humidity according to the functional relationship between the constraint conditions and the air temperature, wind speed, and relative humidity.

[0260] In this step, the control device can set a lower target air temperature (such as 24°C) that makes the wind speed moderate, and a target wind speed range, in combination with equipment design principles and energy consumption constraints. Based on the determined air temperature and wind speed ranges, the control device can further output a target ambient humidity range (40%-60% rh), turn on the ambient dehumidification function, and maintain a constant relative humidity after reaching the target humidity range.

[0261] Step 507: The control device adjusts the air conditioner and the humidity control device respectively according to the control indicators corresponding to the air conditioner and the humidity control device.
