Description

Technical Field

[0001] This application relates to the field of intelligent control technology, and in particular to a non-sensory channel brightness adjustment method and a non-sensory channel system. Background Technology

[0002] With the widespread application of contactless access control systems in public places such as airports and train stations, facial recognition technology has become a core means of identity verification for access control. These systems install cameras within the access channels to capture passengers' facial features in real time and quickly match them with a database. Facial recognition verifies passenger identity information, enabling passengers to board or pass through security without physical contact, thus significantly improving throughput. However, the system's performance is highly dependent on ambient lighting conditions. Direct sunlight can cause overexposure of the camera image or obstruction by shadows, thereby reducing recognition accuracy.

[0003] To address the issue of excessive sunlight, current solutions largely rely on fixed shading structures, simple light control systems, and passive ventilation designs. For example, fixed sunshades cannot dynamically adjust their angle, causing the shading effect to fluctuate with changes in the sun's position; simple light control systems can only achieve imperceptible opening or closing of the passageway, lacking fine-tuning capabilities; and passive ventilation designs depend on fixed vents or natural wind, and are separate from the shading structure, resulting in a sharp drop in ventilation efficiency when shading is applied. While these designs can alleviate the sunlight problem, the enclosed structure restricts airflow, exacerbating the stuffiness in the passageway, especially during peak hours, leading to user discomfort.

[0004] Current shading solutions are mostly static shading or simple light control systems, such as adjusting sunshades by triggering switches with photosensors. While these solutions can partially solve the lighting problem, they lack dynamic and coordinated adjustment capabilities, making it difficult to reconcile the conflict between shading and ventilation, and they cannot adapt to complex environmental changes, such as the angle of the sun, seasons, and weather conditions.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] In one embodiment, Figure 2 A non-intrusive channel brightness adjustment system is shown. The non-intrusive channel system includes: a channel body 10, including a light-shielding top 11, a support column 12, a first light-shielding component 13, a camera component 14, and a channel gate 15.

It mainly includes at least one evenly distributed first light-shielding plate 131, a first motor 133 corresponding to each other located below the light-shielding plate 131, and a first controller 132, a first light intensity sensor 134, and a first angle sensor 135 installed on the light-shielding top 11. The controller 132, motor 133, light intensity sensor 134, and angle sensor 135 are electrically connected to form a closed-loop control system. The first light intensity sensor 134 is used to monitor the light intensity in the channel in real time. When the light intensity exceeds a preset threshold, the controller 132 calculates the target rotation angle of the light shield 131 based on the current astronomical parameters and drives it to rotate precisely through the motor 133. The angle sensor 135 is used to provide feedback on the current angle of the light shield, realizing closed-loop adjustment of control precision and ensuring that the camera area is under suitable lighting conditions.

[0024] The following describes a method for seamless channel brightness adjustment. In one embodiment, this method is applied to a controller, and the flowchart is shown below. Figure 1 As shown, it includes: S100: Obtain the light intensity value within the sensorless channel.

For example, the light intensity value of the face recognition channel refers to the quantitative data of light intensity measured by the light intensity sensor, which represents the light flux received per unit area and directly affects the imaging quality and accuracy of the face recognition system. The first light intensity sensor 134 refers to the device used to detect the ambient light intensity, which can convert light signals into electrical signals and provide real-time data to the controller.

[0031] S400: Drive the first motor 133 to rotate the corresponding first light-shielding plate 131 according to the angle to be rotated, so as to adjust the light-shielding plate from the current angle to the target angle.

[0032] The target angle refers to the ideal angle of the first light-shielding plate 131 calculated to effectively block excess light and optimize the lighting environment in the channel; the current angle refers to the actual angle position of the first light-shielding plate 131 before adjustment, which is usually recorded by the drive system or the first light intensity sensor 134; the first light-shielding plate 131 refers to a rotatable system installed in the sensorless channel to adjust the intensity of sunlight entering the channel and control the amount of light projection by changing the angle.

[0033] Specifically, the first light intensity sensor 134 monitors the light intensity value within the channel in real time, ensuring that the controller can accurately sense environmental changes and determine whether the lighting is suitable for the normal operation of systems such as facial recognition. When the light intensity is too high, the controller calculates the rotation angle of the first light-shielding plate 131 and precisely adjusts its position, effectively reducing the intensity of direct sunlight and minimizing interference from overexposure or shadows on the accuracy of facial recognition. This dynamic adjustment mechanism can flexibly respond to light fluctuations caused by changes in sunlight angle, time, or weather, overcoming the limitations of static shading or simple light control systems. Simultaneously, it ensures the real-time nature and accuracy of light control, not only improving the operational efficiency of the seamless passage system but also significantly improving user comfort during peak hours by reducing glare and optimizing light uniformity. This comprehensive solution effectively resolves the conflict between light and ventilation, creating a more stable and comfortable passage environment and providing users with a more efficient and convenient experience.

[0034] In one embodiment, determining the adjustment angle based on current astronomical positioning parameters includes: Obtain sensorless channel parameter information and current astronomical positioning parameter information; Determine the sun's azimuth angle based on current astronomical positioning parameters; The projection width of the sunshade is determined based on the parameters of the sensorless channel and the angle of the sun's position. The adjustment angle is determined based on the parameters of the sensorless channel, the projection width, and the sun's azimuth angle.

[0035] Specifically, by driving the first motor 133 to adjust the first light-shielding plate 131 from the current angle to the target angle, the system provides an important guarantee for the stable operation of systems such as face recognition and the optimization of user experience. The system can quickly respond to environmental changes, optimize light uniformity, significantly improve the imaging quality and recognition accuracy of the face recognition system, and reduce false recognition or missed recognition problems caused by improper lighting.

[0038] Specifically, the dynamic adjustment mechanism based on multi-parameter comprehensive calculation can flexibly cope with the light fluctuations caused by changes in sunlight angle, time or weather, and maintain the light in the channel within a range suitable for the operation of the face recognition system, thereby significantly improving the recognition accuracy and reducing misidentification or missed recognition caused by improper lighting (such as glare or shadows).

[0039] In one embodiment, determining the solar azimuth angle based on current astronomical positioning parameters includes: Current astronomical positioning parameters include: solar altitude, latitude of the location without sensory input, and solar declination; according to: Determine the azimuth angle of the sun, where A s Indicates the azimuth angle of the sun.

[0040] Among them, the solar azimuth angle refers to the angle between the projection of the sun's rays onto the ground plane and the due north direction; Specifically, Represented as: In this system, n represents the nth day of the year. Taking a non-leap year (365 days) as an example, n represents the cumulative number of days since January 1st. The system determines which month n falls in by accumulating the number of days in each month (January has 31 days, February has 28 days, March has 31 days, etc.) and then calculates the specific date. For example, if n=32, the system calculates 31 days in January and 1 day remains, therefore corresponding to February 1st. Represented as: ; H represents; ; LST is represented as: LT indicates local time; TC is represented as: EoT represents mean time difference, and Longitude represents longitude. LSTM is represented as: LSTM local standard time meridian: ,in This represents the hour difference between local time (LT) and GMT. EoT is represented as: ,in .

[0041] Suppose a seamless passage is set up in a certain location (longitude: 116.4074°, latitude: 39.9042°), on the date 2024 / 12 / 11 at 13:00; Substituting n=345, we get ; ; .

[0042] get ,get ; ; ; ; ; ; get The angle can be calculated. or .

[0043] The system dynamically calculates the sun's trajectory by combining date and time; latitude information is used to locate the sun's trajectory at the security checkpoint; and date and time are combined with astronomical algorithms to dynamically calculate the sun's declination and hour angle. This allows the system to determine the real-time direction and intensity of incident light.

[0044] In one embodiment, determining the projected width of the sunshade based on the sensorless channel parameter information and the sun's azimuth angle includes: The seamless channel parameter information includes at least one of the following: the installation direction parameter of the seamless channel, the length of the seamless channel, the width of the light shield, and the date and time; according to: Determine the projection width, where, The width is represented by , and W represents the width of the light-shielding plate. , Angle A is the angle between the direction of solar incidence and the direction of the normal to the sunshade. s The azimuth angle represents the sun's position, and D represents the installation direction parameter of the sensorless channel.

[0045] Among them, the width of the light shield refers to its physical lateral dimension; the channel length refers to the size of the security check area that needs to be shielded; the latitude information of the security check channel location refers to the geographical coordinates; and the installation direction parameter of the contactless channel refers to the geographical orientation.

[0046] Specifically, the actual width W of the sunshade is 1.5 meters, the solar azimuth As is 135° southeast (0° due north, calculated clockwise), the direction D of the sunshade is 180° due south, and the passage length L is 1 meter; included angle: ; Projection width: ; ; The projection width then covers the channel, effectively blocking direct light.

[0047] The projected width of the sunshade is further calculated to ensure that it effectively blocks excess light at a specific angle, while avoiding excessive blocking that would result in insufficient light. Based on the channel length, installation direction parameters, projected width, and solar azimuth angle, the controller precisely determines the adjustment angle of the sunshade and converts it into the motor rotation angle, driving the sunshade to quickly adjust to the target position.

[0048] In one embodiment, the adjustment angle is determined based on the channel length, the installation direction parameters of the sensorless channel, and the solar azimuth angle, including: according to Determine the adjustment angle in, The values ​​represent the angle that the sunshade needs to be adjusted, L represents the channel length, W represents the width of the sunshade, As represents the solar azimuth angle, and D represents the installation direction parameter of the sensorless channel.

[0049] Specifically, let the channel length L be 1.2 meters, the width of the sunshade W be 1.5 meters, and the solar azimuth angle A be... s With 150° north as 0° and clockwise as the direction, the installation direction D of the sensorless channel is 180° south.

[0050] Calculate the maximum allowable included angle θ max： ; Calculate the actual deviation angle between the solar azimuth angle and the installation direction: ; Determine the adjustment angle : ; A negative adjustment angle (-6.87°) indicates that the sunshade needs to be adjusted in the opposite direction of the sun's incidence (i.e., east) to reduce the actual angle θ and ensure that the projection width covers the length of the channel. The controller controls the motor to deflect the sunshade eastward by approximately 6.87°, reducing the actual angle between the sunlight and the sunshade from 30° to 23.13° (30°-6.87°).

[0051] In one embodiment, determining the rotation angle of the motor shaft based on the adjustment angle includes: according to: The angle will be adjusted from the geographic coordinate system to the machine coordinate system. Among them, D offset This represents the deviation angle between the mechanical zero point and the geographic reference direction. The current position of the light shield corresponds to the geographic direction, so Doffset=D; according to: The adjustment angle is converted into the angle at which the motor shaft will rotate. Where k represents the transmission ratio.

[0052] Among them, the geographic coordinate system refers to a coordinate system based on the Earth's geographical location, usually expressed in angles (degrees), including the azimuth of the sun (horizontal direction, relative to due north) and the altitude angle (vertical direction, relative to the horizon), used to describe the incident direction of sunlight relative to the channel; the mechanical coordinate system refers to the reference coordinate system of the motor in the drive system, representing the actual rotation angle of the sunshade or the motor, usually in the rotation angle (degrees) of the motor shaft, defined based on the current mechanical position of the sunshade and the physical structure of the drive system.

[0053] Specifically, the channel length L is 1.2 meters, the width of the sunshade W is 1.5 meters, the solar azimuth angle As is 150° and due north is 0°. Calculated clockwise, the installation direction D of the sensorless channel is due south at 180°, the adjustment angle is negative -6.87°, the transmission ratio k is 5 (motor rotates 6 revolutions for 5 turns, sunshade rotates 1 revolution), the stepper motor step angle α is 1.8° / step, and the microstepping subdivision multiple mm is 4.

[0054] Convert geographic coordinate system to machine coordinate system: ; in, (The mechanical zero point corresponds to due south). Adjusting the angle to a negative value indicates that eastward compensation is required. After converting to the mechanical coordinate system, this is 173.13° (173.13° westward deflection). Convert the mechanical angle into the angle to be rotated on the motor shaft: ; Equivalent number of loops: (The motor needs to rotate 2.4 revolutions) Motor angle converted to step pulse count: One pulse; The motor receives 1923 pulses, driving the sunshade to deflect 173.13° to the west. The actual adjustment angle is -6.87° (compensated to the east), reducing the angle between the sunlight and the normal of the sunshade from 30° to 23.13°.

[0055] In one embodiment, such as Figure 3 As shown, the first light-shielding assembly 13 further includes a light strip 136, which is disposed on the inner surface of the first light-shielding plate 131. The inner surface of the first light-shielding plate 131 faces the side of the non-intrusive channel when the first light-shielding plate 131 is closed. The light strip 136 is connected to the first controller 132. The method further includes: In response to the light intensity value being less than the second preset light intensity, the controller turns on the light strip 136; In response to a light intensity value greater than or equal to a first preset light intensity, the first controller 132 turns off the light strip 136.

[0056] The light strip 136 is a lighting device installed on the first light shield 131 to provide an auxiliary light source when there is insufficient light, ensuring visibility within the security checkpoint. Brightness refers to the light intensity inside the contactless channel, typically measured in illuminance (e.g., lux). The first controller 132 is the core component of the contactless channel, responsible for receiving data from the light intensity sensor and controlling the switching of the light strip according to preset logic. The first preset illuminance and the second preset illuminance are illuminance threshold values ​​set in the first controller 132, with the first preset illuminance being greater than the second preset illuminance.

[0057] Specifically, through the coordinated operation of the first light intensity sensor 134 and the light strip 136, combined with the intelligent control of the first controller 132, the lighting environment of the security checkpoint is further optimized, improving work efficiency and user experience. The first light intensity sensor 134 monitors the brightness within the contactless channel in real time. When the brightness is lower than the second preset light intensity, the first controller 132 automatically turns on the light strip to provide sufficient auxiliary lighting, ensuring that security personnel can clearly perform their inspections and reducing facial recognition failures due to insufficient light. When the brightness reaches or exceeds the first preset light intensity, the first controller 132 turns off the light strip 136 to avoid unnecessary energy consumption and prevent excessively bright light from causing glare interference to personnel. This intelligent light management not only improves the environmental adaptability of the contactless channel but also further optimizes the lighting and ventilation effects within the channel by dynamically adjusting the lighting in conjunction with the adjustment of the first light shield 131. In addition, this method reduces the need for manual intervention through automated control, improves the system's response speed and operating efficiency, and provides a stable, comfortable, and energy-saving lighting environment for security checkpoints, thereby significantly improving the efficiency of security checks and the comfort experience of passengers.

[0058] In one embodiment, such as Figure 3 As shown, the first light-shielding assembly 13 further includes an angle sensor 135. At least one first light-shielding plate 131 is provided with a corresponding angle sensor 135. The angle sensor 135 is used to monitor the rotation angle of the first light-shielding plate 131. The angle sensor 135 is connected to the controller 132. The method further includes: Determine the maximum angle of rotation of the first light-shielding plate 131; In response to the angle sensor 135 detecting that the first light-shielding plate 131 rotates at an angle equal to the maximum angle, the first controller 132 controls the motor to stop rotating. In response to the angle sensor 135 corresponding to the first light-shielding plate 131 detecting that the first light-shielding plate 131 has not rotated to the target position, the first controller 132 controls the first motor 133 to rotate a second time, driving the first light-shielding plate 131 to rotate to the target position.

[0059] The angle sensor 135 is a precision detection system used to monitor the rotation angle and position of the drive motor in real time, providing accurate feedback data to ensure that the adjustment of the sunshade meets expectations. The first controller 132 is the intelligent core of the system, connected to the angle sensor 135 and the drive motor. It is responsible for receiving feedback data from the angle sensor and controlling the motor's operation according to preset logic. The rotation angle represents the actual angle of rotation of the drive motor, in degrees. The maximum angle is a preset motor rotation limit value, used to prevent the first sunshade 131 from excessively rotating and damaging the equipment or affecting its function. The target position is the ideal angle of the sunshade calculated based on the solar azimuth angle and channel parameters.

[0060] Specifically, the angle sensor 135 monitors the rotation angle of the drive motor in real time. When the motor reaches its maximum angle, the controller immediately stops the motor, effectively preventing damage to the equipment due to excessive rotation and extending the service life of the contactless passage. Simultaneously, if the angle sensor 135 detects that the light-shielding plate has not reached the target position, the first controller 132 instructs the motor to rotate a second time, ensuring that the first light-shielding plate 131 accurately reaches the calculated ideal angle. This dynamically adapts to changes in sunlight, reduces glare interference, and optimizes the lighting environment within the passage. This precise closed-loop control mechanism not only improves the automation level and response speed of the contactless passage but also reduces energy consumption by avoiding unnecessary motor operation. Furthermore, this method complements the previous adjustments to the first light-shielding plate 131, the light control by the first light intensity sensor 134, and the ventilation optimization functions, further enhancing the environmental adaptability of the security checkpoint.

[0061] It should be understood that, although Figure 1 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figure 1 At least some of the steps in the process may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.

[0062] In one embodiment, such as Figure 2 As shown, a seamless channel system is provided, including: Figure 3 As shown, the seamless passage system includes: a passage body 10, including a light-shielding roof 11, a support column 12, a first light-shielding assembly 13, a camera assembly 14, and a passage gate 15. The first light-shielding assembly 13 includes at least one first light-shielding plate 131, a first controller 132, at least one first motor 133, and a first light intensity sensor 134. The at least one first light-shielding plate 131 is used to reduce the intensity of direct sunlight. The at least one first motor 133 corresponds one-to-one with the at least one first light-shielding plate 131 and is used to drive the corresponding first light-shielding plate 131 to rotate. The first controller 132 is used to determine the rotation angle of the at least one first light-shielding plate 131 and control the at least one first motor 133 to drive the corresponding first light-shielding plate 131 to rotate. The first light intensity sensor 134 is used to monitor the light intensity value within the seamless passage. The first controller 132 is configured as follows: Obtain the light intensity value within the sensorless channel; In response to a light intensity value exceeding a first preset light intensity, the adjustment angle is determined based on current astronomical parameter information; Determine the angle to be rotated of the motor shaft based on the adjustment angle; The drive motor drives the corresponding first light-shielding plate 131 to rotate according to the angle to be rotated, so as to adjust the first light-shielding plate 131 from the current angle to the target angle.

[0063] Specifically, the contactless passage system integrates an adjustable light-shielding component 13 into the passage body 10 to achieve intelligent control of the internal lighting environment. Structurally, the passage body consists of a light-shielding roof 11 and supporting columns 12 forming a basic framework. Camera components 14 and passage gates 15 are positioned at key locations within the passage to achieve contactless recognition and automatic access control. The light-shielding component 13 includes at least one first light-shielding plate 131, a corresponding first motor 133, a first controller 132 for controlling the motor's movement, and a first light intensity sensor 134 for detecting the light intensity within the passage. The light intensity sensor 134 monitors the light intensity within the passage in real time. When the monitored value exceeds a first preset light intensity, the controller 132 calculates the required adjustment angle of the light-shielding plate 131 based on current astronomical parameters, determines the rotation angle of the motor shaft, and controls the corresponding motor 133 to drive the light-shielding plate 131 to rotate, adjusting it from the current angle to the target angle. This reduces interference from direct sunlight on camera recognition, ensuring stable and efficient recognition. The system has a well-defined structure and coordinated functions among its components. It can quickly adjust its light-blocking response, effectively adapt to changes in ambient light, improve recognition accuracy and passage efficiency, and enhance the system's intelligence and practicality.

[0064] In one embodiment, the seamless passage system further includes: a passage light-shielding door 20, which includes a door frame 21 and a second light-shielding assembly 22, wherein the second light-shielding assembly 22 includes at least one second light-shielding plate 221, at least one second motor 223, a light intensity sensor, and a second controller 222; the at least one second light-shielding plate 221 is used to reduce the intensity of direct sunlight; the second controller 222 is used to determine the rotation angle of the at least one second light-shielding plate 221 and control the at least one second motor 223 to drive the corresponding second light-shielding plate 221 to rotate; the second light intensity sensor 224 is used to monitor the light intensity value within the seamless passage; wherein the second controller 222 is configured to: Obtain the light intensity value within the sensorless channel; In response to a light intensity value exceeding a first preset light intensity, the adjustment angle is determined based on current astronomical parameter information; Determine the angle to be rotated of the motor shaft based on the adjustment angle; The second motor 223 drives the corresponding second light-shielding plate 221 to rotate according to the angle to be rotated, so as to adjust the second light-shielding plate 221 from the current angle to the target angle.

[0065] Specifically, this seamless passage system further incorporates a passage light-shielding door 20 on top of the main passage structure to enhance precise control over the lighting environment. The light-shielding door 20 is located at the passage entrance or exit area and is connected to the main passage body 10 via a door frame 21, forming a structurally integrated layout. The door frame 21 integrates a second light-shielding component 22, which includes at least one second light-shielding plate 221, a corresponding second motor 223, a second controller 222 for executing control logic, and a second light intensity sensor 224 for monitoring light intensity. The second light-shielding plate 221 is installed inside or above the door frame 21 and is rotated by the motor 223. Its rotation angle is determined by the second controller 222 based on light intensity data and astronomical parameters, further controlling the motor 223 to perform precise rotation, thereby achieving dynamic switching of the light-shielding plate 221 between different angles.

[0066] The second light intensity sensor 224 monitors the light intensity data inside the channel in real time, forming a multi-point light detection system together with the first light intensity sensor 134 located in the main body of the channel. When the system detects that the light intensity inside the channel exceeds a preset threshold, the second controller 222 calculates the target blocking angle of the second light shield 221 based on astronomical parameters such as the current sun position and time of day, and precisely controls the second motor 223 to complete the adjustment action, so that the second light shield 221 effectively blocks the direct light source and optimizes the light distribution in the camera area inside the channel.

[0067] This structural layout allows for spatially partitioned light-blocking functionality. The first light-blocking component 13 primarily controls illumination in the upper and middle sections of the passage, while the second light-blocking component 22 focuses on intervening in strong light at the entrance or exit. Through the coordinated adjustment of the two light-blocking systems, a continuous, layered, and dynamically responsive light environment control system is formed. This multi-level light-blocking mechanism not only improves light-blocking accuracy but also expands the system's applicability under different ambient light conditions, further ensuring the recognition stability of the camera component 14 and the overall operational efficiency of the passage. It also avoids the failure problem of traditional single-point light-blocking solutions under extreme lighting conditions, thus achieving seamless passage guarantee around the clock.
