[0002] Vehicle-mounted light sources are the core of automotive lighting, including headlights, taillights, and interior lights. They serve both lighting safety and signal warning functions, and in recent years have been developing towards energy conservation and intelligence, improving driving visibility and vehicle recognition.

[0003] Patent application number 202411808724.9 discloses an automatic adjustment and control method for vehicle headlights based on environmental perception. The method includes: collecting vehicle data and surrounding environment data, extracting perception features; constructing embedded features based on the perception features, calculating the classification loss and correlation loss of the embedded features, generating an initial headlight adjustment term based on the perception features, and optimizing the initial headlight adjustment term based on the embedded features to generate a headlight adjustment scheme; acquiring driver driving data, determining the driving state, and adjusting the in-vehicle headlights according to the driving state; collecting driver feedback data on the headlight adjustment scheme, optimizing the headlight adjustment scheme, and generating optimization records for storage. The application aims to address the problem that "most existing light source adjustment systems rely on single or a few environmental features for light source adjustment, failing to effectively integrate vehicle dynamic information and environmental change information, resulting in insufficient system response, inflexible adjustment process, lack of personalized and dynamic optimization functions, and difficulty in updating the light source adjustment strategy in real time based on the driver's driving situation, thus reducing user experience and driving safety."

[0004] However, when entering or exiting underground parking garages, the headlights can easily cause visual interference for drivers due to the difference between outdoor light and underground parking garage lighting, increasing driving risks. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an intelligent control method and system for vehicle-mounted light sources, which can effectively solve the problems of the existing technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions;

[0007] This invention discloses an intelligent control system for vehicle-mounted light sources, comprising:

[0008] The system comprises the following modules: a recognition module for acquiring driving scenario information and recognizing the vehicle light source activation mode; an intelligent control module for receiving the vehicle light source activation mode identified by the recognition module, controlling the on / off state of the vehicle light source based on the activation mode, and dynamically adjusting the vehicle light source under the additional mode when the activation mode includes an additional mode; a calibration module for acquiring historical information on the dynamic adjustment of the vehicle light source and calibrating the dynamic adjustment parameters of the vehicle light source in the intelligent control module based on this historical information; and a reset module for resetting the operation of the calibration module.

[0009] Furthermore, the vehicle light source activation modes identified in the identification module include: on, off, gradually brightening, and gradually dimming;

[0010] The recognition module acquires driving scene information based on its subordinate perception module. The perception module is used to perceive ambient light intensity and driving scene images. The perception module is equipped with an interaction unit, which is used to interact with the vehicle central hub in real time to obtain vehicle navigation information and time.

[0011] The ambient light intensity is sensed by a light sensor. Several groups of light sensors are set up and deployed on the front, rear, left, right and top outer surfaces of the vehicle. The driving scene image is collected from the center of the top of the vehicle and then upwards. The gradual brightening and gradual darkening modes in the vehicle light source activation mode are additional modes that enable or disable the vehicle light source activation mode.

[0012] Furthermore, the sensing module operates continuously based on a preset dynamic frequency logic, which is as follows: the current driving speed of the vehicle is obtained in real time through the interaction unit at the vehicle center, and an initial operating frequency and its matching driving speed are set. The slower the current driving speed is compared with the driving speed matched by the initial operating frequency, the more custom the initial operating frequency is adjusted down or maintained. The faster the current driving speed is compared with the driving speed matched by the initial operating frequency, the more the initial operating frequency is adjusted up.

[0013] The interaction unit runs continuously based on a preset operating frequency each time the vehicle is in motion, and the interaction unit is triggered to run once each time the vehicle's onboard central navigation system switches the navigation destination;

[0014] The initial operating frequency of the perception module is higher than the preset operating frequency of the interaction unit.

[0015] Furthermore, the vehicle-mounted light source activation mode recognition logic in the recognition module is represented as follows:

[0016] Real-time detection of ambient light intensity using a light sensor to identify and apply the vehicle's light source activation mode:

[0017] ;

[0018] In the formula: Considering the overall ambient light intensity; Light sensors are deployed on the front, rear, right, left, and top outer surfaces of the vehicle to detect light intensity information in real time; To configure weights; The threshold for determining ambient light intensity;

[0019] The configuration weight The sum is 1, and all are positive numbers and follow the rules. When equation (2) is true, the vehicle light source starts in the off mode; otherwise, the vehicle light source starts in the on mode.

[0020] Furthermore, by using vehicle navigation information obtained from driving scene images and the interaction unit, and time recognition, an additional mode is activated using the vehicle's onboard light source.

[0021] Mode 1: The driving scene image is the sky, and the vehicle light source activation additional mode is none;

[0022] Mode 2: The driving scene image is the ceiling, the current time is 9:00~17:00, the vehicle navigation information shows that the vehicle is within the preset distance threshold from the destination, and the vehicle light source activation mode is gradually darkening;

[0023] Mode 3: The driving scene image is the ceiling, the current time is 17:00~9:00, the vehicle navigation information shows that the vehicle is within the preset distance threshold from the destination, and the vehicle light source activation mode is gradual brightening;

[0024] Mode 4: The driving scene image is the ceiling, the current time is 9:00~17:00, the vehicle navigation information shows that the vehicle is within the preset distance threshold from the departure point, and the vehicle light source activation additional mode is gradually darkening;

[0025] Mode 5: The driving scene image is the ceiling, the current time is 17:00~9:00, the vehicle navigation information shows that the vehicle is within the preset distance threshold from the departure point, and the vehicle light source activation mode is gradual brightening;

[0026] When the vehicle headlight activation mode is either gradually brightening or gradually dimming, the initial brightness of the vehicle headlight is referenced to the preset brightness A in the on state of the vehicle headlight activation mode. In Mode 2, gradually dimming means gradually changing from the maximum limit brightness to the preset brightness A; in Mode 3, gradually brightening means gradually changing from the preset brightness A to the maximum limit brightness; in Mode 4, gradually dimming means gradually changing from the preset brightness A to the minimum limit brightness; and in Mode 5, gradually brightening means gradually changing from the minimum limit brightness to the preset brightness A.

[0027] The preset distance threshold used to determine when the vehicle light source starts in a gradually brightening mode is less than the preset distance threshold used to determine when the vehicle light source starts in a gradually dimming mode.

[0028] Furthermore, the preset brightness A takes the following values: , These represent the maximum and minimum limiting brightness, respectively.

[0029] In the intelligent control module, the logic for dynamically adjusting the vehicle's lighting in the additional mode follows:

[0030] Gradient brightness:

[0031] ;

[0032] Gradient darkening:

[0033] ;

[0034] In the formula, for Phase target brightness; Initial brightness; For real-time timestamps of the control process; The first image of the driving scene is captured using the ceiling as the timestamp. To regulate the unit time interval; This refers to the brightness value used for each adjustment.

[0035] Among them, Mode2 corresponds to and These represent the maximum brightness and the preset brightness A, respectively, corresponding to Mode 3. and These are the preset brightness A and the maximum limit brightness, corresponding to Mode 4. and These are the preset brightness A and the minimum limit brightness, respectively, corresponding to Mode 5. and These are the minimum limit brightness and the preset brightness A, respectively.

[0036] Furthermore, the control unit time interval The brightness value for each adjustment. The value follows:

[0037] The total duration of the dynamic control process corresponding to Mode 2 and Mode 5 is initially set to 2 minutes, and the total duration of the dynamic control process corresponding to Mode 3 and Mode 4 is initially set to 1 minute.

[0038] The number of dynamic control cycles in the dynamic control process is initially set to 30 for Mode 2 and Mode 5, and 20 for Mode 3 and Mode 4.

[0039] The dynamic control process corresponds to Mode 2 and Mode 5. The dynamic control process is 2 minutes / 30 seconds, corresponding to Mode 3 and Mode 4. It is 1min / 20.

[0040] Furthermore, the historical parameters of vehicle light source dynamic control obtained by the calibration module include: the completeness of each gradual brightening control and the completeness of each gradual darkening control during the historical dynamic control of the vehicle light source. The historical parameters of vehicle light source dynamic control are stored in the recording unit set by the lower level of the calibration module.

[0041] The calibration module's calibration target for the dynamic control parameters of the vehicle-mounted light source in the intelligent control module is the total duration of the dynamic control process:

[0042] ;

[0043] In the formula: This represents the total duration of the dynamic control process after calibration. This refers to the total duration of the dynamic adjustment process before calibration. For overall completeness;

[0044] in, For Mode 2 and Mode 5, the value is 2 minutes. For Mode 3 and Mode 4, the value is 1 minute. , This indicates the total number of times the gradual brightening or gradual darkening adjustment was performed in the recording unit. This represents the total duration of the i-th gradual brightening or darkening adjustment. Indicates 1 minute or 2 minutes; This indicates the completeness of the adjustment for the i-th gradual brightening or darkening.

[0045] The trigger condition for resetting the calibration module is as follows: after the calibration module calibrates and applies the total duration of the dynamic control process, if the next dynamic control process is still incomplete, the calibration module is triggered to reset, and the current incomplete dynamic control process is synchronously updated to the recording unit.

[0046] Furthermore, the identification module is interconnected with the sensing module and the intelligent control module via a wireless network. The sensing module is internally connected to the interaction unit via a wireless network. The intelligent control module is interconnected with the calibration module and the reset module via a wireless network. The calibration module is interconnected with the recording unit via a wireless network.

[0047] On the other hand, an intelligent control method for vehicle-mounted light sources includes:

[0048] The system acquires ambient light intensity, driving scene images, vehicle navigation information, and time in real time, and identifies the activation mode of the vehicle's light source based on this information. It controls the on / off state of the light source according to the identified activation mode, dynamically adjusting the brightness when the activation mode includes gradual brightening or dimming. The system dynamically adjusts the scene information sensing frequency based on vehicle speed; the sensing frequency decreases or remains constant at slower speeds and increases at faster speeds, triggering a sensing event when the navigation destination is switched. It determines the basic on / off state of the light source through comprehensive calculation of light intensity at multiple locations, and identifies additional gradual brightening or dimming modes by combining driving scene images, navigation distance, and time. It records the historical completeness information of the vehicle's light source dynamic control, and calibrates the total duration parameter of the dynamic control process based on the historical completeness information and the comprehensive completeness calculation results. If the calibrated dynamic control process is still incomplete, it triggers a reset mechanism for the control parameter calibration and updates the incomplete control process to the historical record.

[0049] Compared with the known prior art, the technical solution provided by this invention has the following beneficial effects:

[0050] This invention provides an intelligent control method and system for vehicle-mounted light sources. During execution, the method and system automatically adapt the light source state based on ambient light intensity, driving scene images, navigation information, and time, achieving intelligent switching between light source on / off and gradual brightness changes. This ensures that brightness changes align with driving scene requirements, reducing visual abruptness. The sensing frequency dynamically adjusts with driving speed, improving sensing accuracy at high speeds and appropriately reducing the frequency at low speeds, thus reducing energy consumption while ensuring accurate scene recognition. Furthermore, historical control records are used to optimize the total duration of dynamic control, ensuring a complete and smooth brightness transition process and improving the comfort of using the vehicle-mounted light source. When control is incomplete, parameter reset and updates are automatically triggered to continuously optimize the control effect, ensuring that the light source state is always precisely matched with the driving scene, time, and journey stage, effectively improving the visual experience and safety during driving.

[0052] Figure 1 This is a schematic diagram of the structure of an intelligent control system for vehicle-mounted light sources;

[0053] Figure 2 This is a flowchart illustrating an intelligent control method for vehicle-mounted light sources. Detailed Implementation

[0054] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0055] The present invention will be further described below with reference to embodiments. Example

[0056] This embodiment provides an intelligent control system for vehicle-mounted light sources, such as... Figure 1 As shown, it includes:

[0057] The recognition module is used to acquire driving scene information and identify the vehicle light source activation mode based on the driving scene information;

[0058] The vehicle light source activation modes identified by the recognition module include: on, off, gradually brightening, and gradually dimming;

[0059] The recognition module acquires driving scene information based on its subordinate perception module. The perception module is used to perceive ambient light intensity and driving scene images. The perception module has an interaction unit inside, which is used to interact with the vehicle central hub in real time to obtain vehicle navigation information and time.

[0060] Among them, ambient light intensity is sensed by light sensors. Several groups of light sensors are set up and deployed on the front, rear, left, right and top outer surfaces of the vehicle. The driving scene image is collected from the center of the top of the vehicle upwards. Gradual brightening and gradual darkening are additional modes that enable or disable the vehicle light source in the vehicle light source activation mode.

[0061] The perception module operates continuously based on a preset dynamic frequency logic. The dynamic frequency logic is as follows: the current driving speed of the vehicle is obtained in real time through the interaction unit at the vehicle center, and the initial operating frequency and its matching driving speed are set. The slower the current driving speed is compared with the driving speed matched by the initial operating frequency, the initial operating frequency is adjusted down or kept up. The faster the current driving speed is compared with the driving speed matched by the initial operating frequency, the initial operating frequency is adjusted up.

[0062] The interaction unit runs continuously based on a preset operating frequency each time the vehicle is in motion, and is triggered to run once each time the vehicle's onboard central navigation system switches to a new navigation destination;

[0063] Among them, the initial operating frequency of the perception module is higher than the preset operating frequency of the interaction unit;

[0064] The logic for recognizing the vehicle light source activation mode in the recognition module is as follows:

[0065] Real-time detection of ambient light intensity using a light sensor to identify and apply the vehicle's light source activation mode:

[0066] ;

[0067] In the formula: For overall ambient light intensity; Light sensors are deployed on the front, rear, right, left, and top outer surfaces of the vehicle to detect light intensity information in real time; To configure weights; The threshold for determining ambient light intensity;

[0068] Configuration weight The sum is 1, and all are positive numbers and follow the rules. When equation (2) is true, the vehicle light source starts in the off mode; otherwise, the vehicle light source starts in the on mode.

[0069] The above formula assigns configuration weights to the light intensity information collected by the light sensors on the front, rear, right, left and top outer surfaces of the vehicle and sums them to obtain the comprehensive ambient light intensity. Then it compares it with the ambient light intensity judgment threshold to determine the on or off state of the vehicle light source. The setting of the configuration weights takes into account the difference in the impact of ambient light from different directions on the driver's field of vision, so that the judgment result is more in line with the actual driving needs.

[0070] Additional modes are activated by using vehicle navigation information obtained from driving scene images and the interaction unit, along with time recognition and onboard light source activation.

[0071] Mode 1: The driving scene image is the sky, and the vehicle light source activation additional mode is none;

[0072] Mode 2: The driving scene image is the ceiling, the current time is 9:00~17:00, the vehicle navigation information shows that the vehicle is within the preset distance threshold from the destination, and the vehicle light source activation mode is gradually darkening;

[0073] Mode 3: The driving scene image is the ceiling, the current time is 17:00~9:00, the vehicle navigation information shows that the vehicle is within the preset distance threshold from the destination, and the vehicle light source activation mode is gradual brightening;

[0074] Mode 4: The driving scene image is the ceiling, the current time is 9:00~17:00, the vehicle navigation information shows that the vehicle is within the preset distance threshold from the departure point, and the vehicle light source activation additional mode is gradually darkening;

[0075] Mode 5: The driving scene image is the ceiling, the current time is 17:00~9:00, the vehicle navigation information shows that the vehicle is within the preset distance threshold from the departure point, and the vehicle light source activation mode is gradual brightening;

[0076] When the vehicle headlight activation mode is either gradually brightening or gradually dimming, the initial brightness of the vehicle headlight is referenced to the preset brightness A in the on state of the vehicle headlight activation mode. In Mode 2, gradually dimming means gradually changing from the maximum limit brightness to the preset brightness A; in Mode 3, gradually brightening means gradually changing from the preset brightness A to the maximum limit brightness; in Mode 4, gradually dimming means gradually changing from the preset brightness A to the minimum limit brightness; and in Mode 5, gradually brightening means gradually changing from the minimum limit brightness to the preset brightness A.

[0077] The preset distance threshold used to determine that the vehicle light source activation additional mode is gradually brightening is less than the preset distance threshold used to determine that the vehicle light source activation additional mode is gradually dimming.

[0078] The preset brightness A value follows: , These represent the maximum and minimum limiting brightness, respectively.

[0079] In the intelligent control module, the logic for dynamically adjusting the vehicle's lighting in the additional mode follows:

[0080] Gradient brightness:

[0081] ;

[0082] Gradient darkening:

[0083] ;

[0084] In the formula, for Phase target brightness; Initial brightness; For real-time timestamps of the control process; The first image of the driving scene is captured using the ceiling as the timestamp. To regulate the unit time interval; This refers to the brightness value used for each adjustment.

[0085] Among them, Mode2 corresponds to and These represent the maximum brightness and the preset brightness A, respectively, corresponding to Mode 3. and These are the preset brightness A and the maximum limit brightness, corresponding to Mode 4. and These are the preset brightness A and the minimum limit brightness, respectively, corresponding to Mode 5. and These are the minimum limit brightness and the preset brightness A, respectively.

[0086] The above formula is for two additional modes: gradual brightening and gradual darkening. The formula uses the starting timestamp, real-time timestamp, unit time interval, and brightness value adjusted each time as parameters to allow the target brightness to gradually transition from the initial brightness to the target brightness. The setting of the initial brightness and target brightness in different modes, combined with the gradual adjustment in the time dimension, can avoid sudden brightness changes from stimulating the driver's vision and improve driving comfort.

[0087] Adjustment unit time interval The brightness value for each adjustment. The value follows:

[0088] The total duration of the dynamic control process corresponding to Mode 2 and Mode 5 is initially set to 2 minutes, and the total duration of the dynamic control process corresponding to Mode 3 and Mode 4 is initially set to 1 minute.

[0089] The number of dynamic control cycles in the dynamic control process is initially set to 30 for Mode 2 and Mode 5, and 20 for Mode 3 and Mode 4.

[0090] The dynamic control process corresponds to Mode 2 and Mode 5. The dynamic control process is 2 minutes / 30 seconds, corresponding to Mode 3 and Mode 4. 1min / 20;

[0091] The intelligent control module is used to receive the vehicle light source start-up mode identified by the recognition module, control the vehicle light source to turn on and off based on the vehicle light source start-up mode, and dynamically adjust the vehicle light source in the additional mode when the vehicle light source start-up mode includes an additional mode.

[0092] The calibration module is used to acquire historical information on the dynamic control of vehicle light sources and to calibrate the dynamic control parameters of vehicle light sources in the intelligent control module based on the historical information on the dynamic control of vehicle light sources.

[0093] The historical parameters of vehicle light source dynamic control obtained by the calibration module include: the completeness of each gradual brightening control and the completeness of each gradual darkening control during the historical dynamic control process of vehicle light source. The historical parameters of vehicle light source dynamic control are stored in the recording unit set by the lower level of the calibration module.

[0094] The calibration module's calibration target for the dynamic control parameters of the vehicle-mounted light source in the intelligent control module is the total duration of the dynamic control process:

[0095] ;

[0096] In the formula: This represents the total duration of the dynamic control process after calibration. This refers to the total duration of the dynamic adjustment process before calibration. For overall completeness;

[0097] in, For Mode 2 and Mode 5, the value is 2 minutes. For Mode 3 and Mode 4, the value is 1 minute. , This indicates the total number of times the gradual brightening or gradual darkening adjustment was performed in the recording unit. This represents the total duration of the i-th gradual brightening or darkening adjustment. Indicates 1 minute or 2 minutes; This indicates the completeness of the adjustment for the i-th gradual brightening or darkening.

[0098] The above formula is based on the total duration before calibration, combined with the comprehensive integrity calculated from the historical control integrity, to determine the total duration after calibration. The comprehensive integrity is obtained by statistically analyzing the matching degree between the actual duration of each historical control and the set total duration, so that the total duration after calibration can better adapt to the actual control execution and reduce the problem of poor brightness adjustment effect caused by incomplete control.

[0099] The trigger condition for resetting the calibration module is as follows: after the calibration module calibrates and applies the total duration of the dynamic control process, if the next dynamic control process is still incomplete, the calibration module is triggered to reset, and the current incomplete dynamic control process is synchronously updated to the recording unit.

[0100] The reset module is used to reset the calibration module's operation.

[0101] The identification module is interconnected with the sensing module and the intelligent control module via a wireless network. The sensing module is internally connected to the interaction unit via a wireless network. The intelligent control module is interconnected with the calibration module and the reset module via a wireless network. The calibration module is interconnected with the recording unit via a wireless network.

[0102] In this embodiment, the recognition module collects ambient light intensity through multi-directional light sensors and driving scene images from the top. It then obtains navigation information and time through the interaction unit, dynamically adjusting the operating frequency according to vehicle speed (higher frequency for faster speeds). Based on a weighted calculation of ambient light intensity, it determines whether the light source is "on" or "off." Combining scene images, time, and navigation distance, it identifies an additional mode: when the scene is a ceiling, from 9:00 to 17:00, the light gradually dims within a threshold range from the destination / departure point (from maximum brightness to preset brightness A, and from A to minimum brightness), and from 17:00 to 9:00, the light gradually brightens within the corresponding threshold range (from A to maximum brightness, and from A to minimum brightness). The brightness is reduced to A), and the threshold for gradual brightening is even smaller; the intelligent control module controls the opening and closing of the light source according to the recognition result, and dynamically adjusts it according to logic in the additional mode. The initial total duration of Mode 2 / 5 is 2 minutes (30 adjustments, Δt=2min / 30), and the initial duration of Mode 3 / 4 is 1 minute (20 adjustments, Δt=1min / 20); the calibration module calibrates the total duration based on the historical adjustment completeness (actual duration to total duration ratio) stored in the recording unit (calibrated duration = initial duration × average comprehensive completeness); if the next adjustment is still incomplete after calibration, the reset module triggers the calibration module to reset and synchronously updates the incomplete record.

[0103] In the above embodiments, the system can automatically adjust the vehicle's light source based on ambient light, driving scenario, time, and navigation information. It automatically turns on when the light is dim and turns off when the light is bright. In scenarios such as entering and exiting a garage, the brightness will be gradually adjusted to reduce visual impact. With long-term use, the adjustment time will be optimized to make the brightness changes more in line with driving needs, improve driving comfort and safety, and bring a more intelligent and smooth driving experience. Example

[0104] At the implementation level, based on Example 1, this example refers to... Figure 2 A further detailed description of the intelligent control system for an on-board light source in Example 1 is provided below:

[0105] A method for intelligent control of vehicle-mounted light sources, comprising:

[0106] It can acquire ambient light intensity, driving scene images, vehicle navigation information and time in real time, and identify the start-up mode of the vehicle light source based on the information;

[0107] The system controls the opening and closing of the light source based on the identified vehicle light source start-up mode. When the start-up mode includes gradual brightening or dimming, the brightness of the light source is dynamically adjusted.

[0108] The frequency of scene information perception is dynamically adjusted based on the vehicle's driving speed. The slower the driving speed, the lower or constant the perception frequency is, and the faster the driving speed, the higher the frequency is. Information perception is triggered once when the navigation destination is switched.

[0109] The basic on / off state of the light source is determined by comprehensive calculation of light intensity at multiple locations, and additional modes of gradual brightening or darkening are identified by combining driving scene images, navigation distance and time.

[0110] Record the historical integrity information of the dynamic control of the vehicle light source, and calibrate the total duration parameter of the dynamic control process based on the historical integrity information and the comprehensive integrity calculation results;

[0111] If the calibrated dynamic control process is still incomplete, the control parameter calibration mechanism is reset, and the incomplete control process is updated to the historical record.

[0112] In summary, the methods and systems described in the above embodiments automatically adapt the light source status based on ambient light intensity, driving scene images, navigation information, and time during execution. This enables intelligent switching between light source on / off and gradual brightness changes, ensuring that brightness variations align with driving scenario requirements and reducing visual abruptness. The sensing frequency dynamically adjusts with driving speed, improving sensing accuracy at high speeds and appropriately reducing frequency at low speeds. This reduces energy consumption while maintaining scene recognition accuracy. Furthermore, historical control records optimize the total duration of dynamic control, ensuring a complete and smooth brightness transition process and improving the comfort of using in-vehicle light sources. When control is incomplete, parameters are automatically reset and updated to continuously optimize the control effect, ensuring that the light source status always precisely matches the driving scenario, time, and travel stage, effectively improving the visual experience and safety during driving.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
