[0024] Embodiment 1

[0025] The present invention provides a cabin intelligent lighting adjustment system, including a ship motion sensing module, a human body data collection module, and an environment detection module. The ship motion sensing module, the human body data collection module, and the environment detection module respectively collect corresponding data and perform data integration. Subsequently, the data enters the intelligent control unit 11 and the intelligent lighting adjustment module in sequence, and finally controls the intelligent lamp group 10. The specific process control schematic diagram is as Figure 1 shown, and the layout schematic diagram of each module is as Figure 2 shown.

[0026] As Figure 3As shown, the ship motion sensing module includes a gyroscope 13, an accelerometer 12, a magnetometer sensor 9 and a power sensor 8. The gyroscope 13 detects the angular velocity of the ship in real time to accurately grasp the changes in the ship's heading. The accelerometer 12 is used to measure the acceleration of the ship in three axes and analyze the degree of turbulence and shaking of the ship. The magnetometer sensor 9 is used to sense the changes in the geomagnetic field around the ship and provide data support for the accurate calculation of the heading. The power sensor 8 will be connected to the ship's host system to monitor the operating power of the host in real time, detect the power output of the host, and understand the operating load of the ship. These sensors transmit data to the data acquisition unit 15, and then transmit the processed data to the intelligent control unit 11 through a standard communication protocol. The intelligent control unit 11 performs in-depth analysis and processing on the received data.

[0027] The calculation formula of ship heading angle is as follows:

[0028] θ(t)=θ(t-1)+ωΔt;

[0029] Among them, θ(t) represents the heading angle at the current time t; ω represents the angular velocity output by the gyroscope; Δt represents the time interval;

[0030] The acceleration sensor 12 generally outputs acceleration values ​​of the ship in three directions:

[0031] a x : acceleration along the X axis;

[0032] a y : acceleration along the Y axis;

[0033] a z : acceleration along the Z axis;

[0034] The magnitude of acceleration is used to determine the motion state of the ship. The total amount of acceleration a is calculated using the following formula:

[0035]

[0036] If a exceeds a certain threshold, it means that the ship has undergone violent movements, which may affect the comfort of the cabin and trigger the lighting adjustment system to make adaptive adjustments.

[0037] like Figure 4 As shown, the human body data collection module includes a millimeter wave radar 6, a biosensor 7, a pressure sensor 14, an infrared sensor 1, and a camera 3, which monitor the dynamics of the people in the cabin and the physiological and psychological status of the people in the cabin in all directions. The millimeter wave radar 6 has high broadband characteristics, adopts multi-antenna array technology and intelligent algorithm optimization, and locates the position of the people in real time. By transmitting and receiving millimeter wave signals, analyzing the time difference and phase change of signal reflection, the three-dimensional coordinate position of the people in the cabin is accurately determined.

[0038] The millimeter-wave radar 6 determines the three-dimensional coordinate position of a person through the following formula:

[0039]

[0040] Where d represents the distance to the target; c represents the propagation speed of electromagnetic waves;

[0041] Physiological signal detection: The detection of minute physiological changes such as heartbeat or breathing usually relies on minute phase changes, and the calculation method is as follows:

[0042]

[0043] Where Δφ represents the phase change; ΔR represents the minute displacement of the target; λ represents the wavelength of the millimeter wave.

[0044] Heart rate and breathing rate: Signals obtained through an electromagnetic surface sensor are used to monitor minute changes in heartbeat and breathing. The heart rate HR is usually measured in beats per minute (BPM), and the formula is as follows:

[0045]

[0046] Subsequently, real-time position coordinate output is performed through a centimeter-level positioning algorithm, and then it is judged whether there is someone in the current area to generate the corresponding energy-saving strategy for the current area.

[0047] The light intensity and color temperature are different at different positions where people are located. The color temperature can be adjusted according to people's psychological activities or emotions. When the position where a person is located is a workbench, the light at the workbench is adjusted to cold light of 6000k to help the crew focus and stay calm. When a person is sleeping, the light is adjusted to warm light of 3000k to enhance the drowsiness of the human body and finally weaken or turn off. As Figure 1 、 Figure 2 shown, if a person enters the cabin, the condition for turning off the light is not met, and the intelligent control unit 11 performs data analysis and processing and subsequent operations; if a person leaves the cabin, the condition for turning off the light is met, and then a light adjustment instruction is generated and the instruction is sent for subsequent operations.

[0048] The biosensor 7 uses an electromagnetic metasurface sensor and is installed at positions such as seat belts and seats in the cabin. Even through clothing, it can capture minute heartbeat and breathing signals in a complex dynamic environment.

[0049] The infrared sensor 1 monitors the infrared radiation emitted by the human body and judges the activity state of the person by sensing the intensity and distribution of the infrared radiation. The camera 3 captures the facial expressions, body movements, etc. of the person and assists in identifying the behavior and emotional state of the person through image recognition algorithms.

[0050] The pressure sensor 14 is installed at positions such as seats and beds, and judges the posture and movement of a person by sensing the pressure distribution of the human body on the surface of an object. When a person sits down, the pressure sensor 14 detects the pressure distribution of the human body part on the seat, converts the pressure signal into an electrical signal through the change of resistance or capacitance, and transmits it to the data processing unit.

[0051] The data collected by these sensors is integrated and preprocessed by the data acquisition unit 15. The data acquisition unit 15 processes the signals of different sensors, such as amplification, filtering, analog-to-digital conversion, etc., unifies them into digital signals, and encapsulates them according to a specific data format. Then, the processed data is transmitted to the intelligent control unit 11 through a standard communication protocol. The intelligent control unit 11 deeply analyzes and processes the received data and generates a lighting adjustment instruction.

[0052] As Figure 5 shown, the environmental detection module includes a light intensity sensor 4, a temperature and humidity sensor 5, and a noise sensor 2. Multiple sensors cooperate to monitor the light, temperature, humidity, and noise levels in the cabin in real time. These sensors are all connected to the intelligent control unit 11 through the data acquisition unit 15. The data acquisition unit 15 is responsible for collecting real-time environmental data from each sensor and transmitting this data to the intelligent control unit 11, providing data support for the intelligent control unit 11 to optimize lighting adjustment.

[0053] Each time the light intensity sensor 4 is updated, the newly measured light intensity is added to a window with a length of 5 seconds, and the average value of the data in the window is calculated as the output.

[0054] Let the current light intensity be L(n), the window size be 5, and the filtered light intensity be L filtered (n) then:;

[0055]

[0056] Among them, L(n) represents the light intensity value at the nth moment; L filtered (n) is the filtered light intensity.

[0057] Temperature detection is similar to light intensity detection. First, filtering is performed. Simple moving average filtering is used to smooth the data and remove short-term noise. Subsequently, a calibration factor a is introduced to calibrate and compensate the test results. Specifically:

[0058]

[0059] T true = a × T filtered [n] + b;

[0060] Among them, T[n] represents the temperature value at the nth moment; T filtered [n] is the filtered temperature intensity; T true represents the corrected test result; b represents the offset, which is measured through known standard temperature points.

[0061] Noise detection is similar to temperature and light intensity detection. First, time-domain filtering is performed, and the average value of the past 5 noise values is calculated to output the smoothed noise level. Specifically:

[0062]

[0063] Among them, N[n] represents the noise level at the nth moment; N filtered [n] represents the filtered noise level.

[0064] Subsequently, frequency-domain analysis and processing of the noise are carried out. Specifically:

[0065] The Fourier transform is used to convert the time-domain signal into a frequency-domain signal, and low-pass filtering is performed, that is, a cut-off frequency is set to filter out the frequency components higher than this frequency, so as to retain the low-frequency part. Then, the filtered frequency-domain signal is converted back to the time-domain signal through the inverse Fourier transform to obtain the result after low-pass filtering. Finally, noise reduction processing is performed on the result.

[0066] The intelligent control unit 11 includes multiple data acquisition units 15. The multiple data acquisition units 15 are respectively installed in each cabin and are responsible for real-time acquisition of the environmental, human body, and ship motion data in each cabin, and data transmission with sensor modules such as the environmental detection module, human body data collection module, and ship motion sensing module through the Zigbee standard communication protocol, and transmitting the acquired real-time data to the intelligent control unit 11.

[0067] The control unit preprocesses and integrates these data and extracts key features. Next, the cabin control unit uses fuzzy control algorithms and reinforcement learning algorithms to analyze the acquired data, optimize the light brightness and color temperature, and generate specific adjustment instructions. These instructions are transmitted to the intelligent light adjustment module through the communication protocol to control the brightness and color temperature adjustment of the LED intelligent lights, thereby achieving a balance between comfort and energy efficiency.

[0068] Each cabin control unit also regularly summarizes the processed data and transmits it to the total control unit through an efficient communication protocol. The total control unit comprehensively analyzes the control data of all cabins, optimizes the lighting adjustment strategy of the whole ship to ensure that the lighting management of the whole ship reaches the best effect. At the same time, the total control unit can coordinate the lighting adjustments of different cabins, adjust the lighting settings of each cabin to ensure the maximum energy efficiency of the whole ship and improve the comfort of crew members and passengers. The workflow diagram of the intelligent control unit 11 is as Figure 6 shown.

[0069] The intelligent lighting adjustment module includes a driving circuit and an interface, which are used to receive the instructions sent by the intelligent control unit 11 to accurately adjust the lighting brightness and color temperature. The driving circuit adjusts the current and voltage according to the instructions to precisely control the brightness and color temperature changes of the LED lights, ensuring smooth lighting changes without flicker. This module can also automatically adjust the on / off state of the lights according to human activities, such as automatically turning off the lights when people leave and automatically turning on the lights when people enter.

[0070] The intelligent lamp group 10 uses high-efficiency and energy-saving LED light sources and has a built-in driving circuit, which can precisely adjust the brightness and color temperature to meet the lighting requirements in different cabin environments. The intelligent lamp group 10 supports remote control, can receive the instructions sent by the intelligent control unit 11, and has a flicker-free technology to ensure a comfortable and stable lighting effect. The LED intelligent lamp also supports wireless or wired communication protocols to interact with other intelligent devices, thus improving the intelligence level of the system.

[0071] Therefore, by adopting the above-mentioned cabin intelligent lighting adjustment system, the present invention can intelligently adjust the lighting, improve energy efficiency, reduce energy consumption, be convenient to operate, enhance the user experience, and improve the overall energy-saving effect of the ship cabin.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present invention, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present invention.
