Factors such as temperature, humidity, and light in the external environment can significantly affect the stability of the cabin environment. In addition, traditional cabin environment physical data statically regulates the cabin environment, ignoring the feedback of human physiological data on environmental control needs. The human physiological state will produce different reactions in different environments. Therefore, the introduction of physiological data perception combined with the regulation of multimodal environmental data can achieve more personalized cabin environment management.

The domain control strategy is adaptively generated by screening historical domain control strategy records to make secondary adjustments to the environmental parameters in the cockpit.
[0018] Reference Figure 2 As shown, real-time environmental parameters inside and outside the cockpit are collected, and a dynamic correlation model between the real-time environmental parameter changes outside the cockpit and the expected changes in the environmental parameters inside the cockpit is established. Specifically, it includes: At set time interval Collect the external environment parameters of the cockpit and the real-time environment parameters of the cockpit, and establish a synchronous data sequence of the environment status inside and outside the cockpit; Preprocess and normalize the synchronous data sequence, and use the processed data as the initial input of the dynamic correlation model of the cabin internal and external environmental parameters; The multiple linear regression model is used to associate the changes in the external environment of the cockpit with the response of the internal environment. Through the multiple linear regression model, a dynamic correlation model between the external environment parameters and the internal environment parameters is established. The multiple regression equation is expressed as follows: ; In the formula, is the data of the i-th environmental parameter in the cabin at time t, is the data of the mth environmental parameter outside the cabin at the previous moment of time t, is the regression coefficient of the i-th cabin environment parameter corresponding to the m-th cabin environment parameter; The sliding time window for training the dynamic correlation model of the cabin internal and external environmental parameters is set, and the synchronous data sequence of the cabin internal and external environmental states collected within the sliding time window is brought into the multivariate linear regression model to calculate and adjust the regression coefficient in real time.
[0019] Reference Figure 3 As shown, based on the deviation between the expected environmental parameters in the cabin and the ideal environmental parameters, a pre-adjustment optimization feedback loop is constructed, and a feedback closed-loop adjustment of the environmental parameters in the cabin is performed, specifically including: The system uses a proportional-integral-derivative controller as the core controller of the feedback loop. It dynamically adjusts the cabin's internal environmental parameters based on the real-time deviation between the ideal environmental parameters and the expected environmental parameters in the cabin. Specifically: Set the ideal environment parameters in the cockpit; The current real-time external environment parameters of the cockpit are brought into the multivariate linear regression model to obtain the expected internal environment parameters of the cockpit, which are used to describe the predicted values of the environment parameters at the next moment; By evaluating the immediate response to the real-time deviation between the expected environmental parameters and the ideal environmental parameters inside the cockpit, the cumulative impact of historical deviations, and the changing trend of future deviations, the proportional gain, integral gain, and differential gain corresponding to the feedback adjustment are determined respectively; The gain parameters can be calculated based on the multiple regression model, and the immediate response of the deviation (parameter real-time data) and the cumulative impact of the historical deviation (parameter historical average data) (parameter time series differential) are respectively brought into the multiple regression model to determine the regression parameters.
[0020] Among them, the proportional gain directly reflects the magnitude of the current environmental parameter error and immediately amplifies it to respond quickly. This immediate response can predict the continued trend of the current error in a short period of time.
[0021] The integral gain accumulates environmental parameters over a period of time, identifies steady-state errors, and provides a prediction of long-term trends for future adjustments. By eliminating accumulated errors, the system can achieve stable target parameters in the long term.
[0022] The differential gain amplifies the error change rate, allowing the system to predict future trends in environmental parameters. The differential gain responds before future trends occur, reducing system fluctuations and overshoots through advance control.

[0025] Among them, the situation type classification formula is: ; In the formula, The type of situation to be identified, For situation type The characteristic center, rate the environmental context; Each scenario type represents a specific combination of environmental conditions, for example, “high temperature and high humidity”, “low light and low air quality” and other scenario categories. The scenario matching degree indicates the degree of conformity of the specific parameters of the environmental condition combination to the scenario category.

[0028] Based on historical data analysis, the system deeply establishes the correlation between environmental situation types and human physiological states. By using regression analysis and correlation calculation, the system can quantify the response characteristics of human physiological states under different situation types, thereby providing more precise adaptive support for cabin environment control.
[0029] Reference Figure 6 As shown, based on the prediction of expected environmental parameters in the cockpit, environmental situation recognition, and the relationship between situation type and human physiological state, the human physiological state is predicted, and the domain control strategy is adaptively generated by screening historical domain control strategy records.

A domain control optimization system based on in-cabin environment recognition, used to implement a domain control optimization method based on in-cabin environment recognition as claimed in any one of claims 1 to 6, characterized in that: include: An environmental parameter change prediction module, which establishes a synchronous data sequence of the internal and external environmental states of the cabin, uses a regression model to associate the changes in the external environment of the cabin with the response of the internal environment, and establishes a dynamic correlation model of the internal and external environmental parameters of the cabin through a multivariate linear regression model; A domain control primary adjustment module, wherein the domain control primary adjustment module uses a proportional-integral-differential controller as a core controller of a feedback loop, establishes a feedback formula through proportional gain, integral gain and differential gain to determine the adjustment amplitude of various environmental parameters in the cabin, and adjusts the internal environmental parameters of the cabin once based on the real-time deviation value between the ideal environmental parameters and the expected environmental parameters in the cabin, until the real-time adjustment amplitude of various environmental parameters controlled by the feedback loop is less than the set minimum adjustment amplitude threshold and tends to be stable; An environmental situation type recognition module, which unifies historical multi-source environmental parameters based on a multimodal data fusion model, calculates the cabin environmental situation scores corresponding to the historical multi-source environmental parameters, and establishes an association recognition model corresponding to the environmental situation type of the environmental parameter feature classification based on a clustering algorithm, so as to identify the environmental situation type in the cabin and the situation matching degree; A human physiological state prediction module, which determines the correlation between the environmental situation type and the human physiological state through a regression analysis model based on the environmental situation type recognition result of the historical environmental situation data set; A domain control secondary adjustment module predicts the human physiological state at the next moment based on the prediction of expected environmental parameters in the cabin, environmental situation recognition, and the correlation between situation types and human physiological states. Based on the feedback of historical human physiological state parameter changes, the module dynamically sets weights for the domain control strategies corresponding to the historical human physiological state parameter records and performs secondary adjustments to the cabin environmental parameters corresponding to the domain control strategies.
