[0035] Example 1

Dynamic lighting is provided by projecting light sources through lights, and fish are attracted by adjusting light sources, helping anglers to accurately observe the floating and water surface dynamics in night environments, while avoiding light pollution from interfering with the field of vision.

[0038] The specific implementation is as follows:

[0039] like Figure 1As shown, it is a schematic diagram of the structure of a night fishing auxiliary control system based on DLP projection lights provided by an embodiment of the present invention.

[0040] As an example, the system includes: a DLP projection headlight 1, a vehicle cockpit domain controller 2, an underwater sensor module 3 and a mobile terminal 4; the underwater sensor module 3 is used to collect underwater fish distribution data, water temperature data and light intensity data, and feed the data back to the vehicle cockpit domain controller 2; the vehicle cockpit domain controller 2 is used to dynamically generate control parameters of the DLP projection headlight 1 according to a built-in fusion algorithm based on the data transmitted by the underwater sensor module 3; the DLP projection headlight 1 is used to control one or a combination of projected light intensity, spot shape, light direction and color temperature based on the control parameters of the vehicle cockpit domain controller 2; the mobile terminal 4 interacts bidirectionally with the vehicle cockpit domain controller 2 to obtain and display the data transmitted by the underwater sensor module 3 in real time; and the mobile terminal 4 is used to send control instructions to the vehicle cockpit domain controller 2, so that the vehicle cockpit domain controller 2 adjusts the lighting mode based on the control instructions.

[0041] In some feasible implementations, the underwater sensor module 3 integrates a sonar 300, a temperature sensor 310, and a light sensor 320; the sonar 300 is used to obtain one or a combination of the position, size, swimming direction, and swimming speed of the fish school; the temperature sensor 310 is used to obtain underwater temperature data; and the light sensor 320 is used to obtain underwater light intensity data. Specifically, the sonar detector continuously emits sound waves and receives reflected waves, and detects the position, number, and movement trend of the fish school by analyzing the time, intensity, and other information of the reflected waves, and transmits these data to the vehicle cabin domain controller 2 in real time. The temperature sensor monitors the underwater temperature in real time and sends the temperature data to the vehicle cabin domain controller 2 in the form of a digital signal. The light sensor continuously senses the underwater light intensity and also feeds back the data to the vehicle cabin domain controller 2, providing comprehensive data support for the system to dynamically adjust the projection mode.

[0042] In some feasible implementations, the vehicle cockpit domain controller 2 is integrated with a fusion algorithm, including a density-based DBSCAN clustering algorithm and a Kalman filter, a water temperature-light coupling model, and a light spot shape adjustment strategy; the density-based DBSCAN clustering algorithm and the Kalman filter are used to spatially cluster the point cloud data of the fish school based on the position, size, swimming direction, and swimming speed data of the fish school transmitted by the received sonar; the water temperature-light coupling model is used to calculate the optimal light wavelength and light intensity based on the underwater temperature data and underwater light data transmitted by the temperature sensor and the light sensor; the light spot shape adjustment strategy is used to generate the light spot shape based on the underwater fish distribution data. Preferably, the density-based DBSCAN clustering algorithm is used to identify effective fish school clusters and obtain the centroid coordinates of the fish school; the Kalman filter is used to predict the movement trajectory of the fish school and obtain the movement velocity vector of the fish school. Specifically, the processing of sonar data includes: noise reduction and filtering: wavelet transform is used to eliminate water disturbance noise; spatial clustering: DBSCAN algorithm is used to identify effective fish clusters, with a minimum density of 5 fish per cubic meter; motion tracking: Kalman filter is used to predict the movement trajectory of fish schools. After processing the sonar data, the coordinates of the fish school's centroid, the moving speed vector and the cluster density heat map are output.

[0043] In some feasible implementations, control parameters for adjusting the illumination direction of the DLP projection vehicle light are generated based on the centroid coordinates of the fish school and the moving speed vector of the fish school, and the illumination direction control parameters include the center coordinates of the light spot and the coverage of the light spot; the center coordinates of the light spot are dynamically offset by a preset offset according to the centroid coordinates of the fish school; the coverage of the light spot is positively correlated with the standard deviation of the fish school distribution. Specifically, the center coordinates of the light spot can be dynamically offset according to the centroid coordinates of the fish school, with a maximum offset of ±2m, and the coverage of the light spot is positively correlated with the standard deviation σ of the fish school distribution, such as 4σ.

[0044] In some feasible implementations, the mathematical formula of the water temperature-light coupling model is:

[0045] λ opt (T) = λ base +k·(TT ref ) 2 ;

[0046]

[0047] In the formula, λ opt (T) represents the optimal wavelength, λ base represents the basic preferred wavelength of the target fish, which is pre-calibrated through experiments, T represents the real-time water temperature, and T ref represents the reference temperature, which is 20℃, k represents the fish sensitivity coefficient, I compIndicates the output light intensity, I base Indicates the reference light intensity, L env Indicates the ambient light intensity, L threshold represents the interference threshold, Υ, δ represents the compensation coefficient. Specifically, taking carp as an example, Υ takes the value of 0.5, δ takes the value of 1.2, and L threshold The value is 50lux, and the k value is 0.8nm / ℃ 2 .

[0048] More specifically, different fish have significant differences in spectral sensitivity, such as carp preferring 590-620nm orange-red light, and perch being sensitive to 480-520nm blue-green light. In addition, changes in water temperature will change the metabolic rate of fish, thereby affecting their phototaxis behavior. For example, experimental data show that within the range of 15-25℃, the intensity of phototaxis response is positively correlated with temperature. Therefore, by establishing a water temperature-light coupling model, the biological characteristics of fish, light propagation attenuation and environmental interference are incorporated into a unified model, achieving precise matching of light parameters with the underwater environment, and providing a scientific and quantitative control basis for night fishing.

[0049] In some feasible embodiments, the light spot shape adjustment strategy includes: judging the aggregation state, swimming direction and swimming speed of the fish school according to the sonar data, and generating the light spot shape adjustment strategy based on the aggregation state, swimming direction and swimming speed of the fish school; and / or formulating the corresponding light spot shape adjustment strategy in combination with the underwater temperature data and the underwater light intensity data; and / or formulating the corresponding light spot shape adjustment strategy based on the preferences and behavioral habits of different fish for light. Specifically, judging the aggregation state, swimming direction and speed of the fish school according to the sonar data. If the fish school is scattered, the light spot shape can be adjusted to a large area of ​​scattering to cover more areas; if the fish school swims linearly, the light spot can be adjusted to a long strip. Combined with the water temperature and light intensity data for comprehensive analysis. When the water temperature is low, some fish may be more inclined to gather in areas with warm light, and the light spot can be adjusted to a more concentrated circle to attract the fish school; when the underwater light is strong, the light spot brightness can be reduced and adjusted to a softer shape to avoid scaring the fish school. Based on the light preferences and behavioral habits of different fish, corresponding light spot shape strategies are formulated. For example, for fish with strong phototropism, bright and regularly shaped light spots can be used; for fish that are more sensitive to light, soft and irregular light spots can be used.

[0050] In some feasible implementations, the database in the mobile terminal stores target fish and the spectral preference, suitable water temperature range and phototropism behavior pattern corresponding to the target fish; the mobile terminal is also used to directly generate control instructions based on the target fish input by the user, and control the DLP projection lamp to project with the lighting parameters stored in the database. Specifically, in the initial stage, the user can manually input the actual fishing situation on the APP, such as the target fish, and the spectral preference, suitable water temperature range and phototropism behavior pattern of the target fish will be directly generated. The vehicle cabin domain controller 2 controls the DLP projection lamp 1 based on the instruction. However, since the fish school is swimming, it is necessary to continuously optimize the control instructions of the vehicle cabin domain controller 2 through the data collected by the underwater sensor module in real time, so that its control over the DLP projection lamp 1 is more intelligent.

[0051] In some feasible implementations, the mobile terminal 4 is integrated with an intelligent recommendation module, and the intelligent recommendation module is used to recommend optimal light intensity-color temperature combination data based on historical data based on data transmitted by the underwater sensor module.

[0052] In some feasible implementations, the different functional modules in the system are summarized as follows:

[0053] Mobile APP (mobile terminal) 4: After the user opens the mobile APP, he can see a variety of lighting mode options on the operation interface, such as strong light mode for initial attraction of fish, soft light mode for simulating natural moonlight to avoid disturbing fish, etc. The user selects the appropriate lighting mode according to the actual fishing scene, and the APP sends the control command to the vehicle cockpit domain controller. At the same time, the APP receives underwater sensor data from the cockpit domain controller in real time, and displays the distribution of fish in the form of charts or maps, so that users can understand the location of fish. For example, when the sonar detects that fish gather in a certain area, the APP will highlight the area on the interface and give suggestions based on the sensor data, such as adjusting the light color to blue to attract certain specific fish species.

[0054] Vehicle cockpit domain controller 2: As the core computing and control unit of the system, once receiving the user's command, it will immediately parse the command and control the DLP projection lights to switch to the corresponding projection mode according to the command content. When processing the data of the underwater sensor module, the cockpit domain controller uses the built-in data analysis algorithm to analyze the location, movement trends and other information of the fish school in real time. For example, when the temperature sensor detects that the water temperature is low and the sonar detects that the fish school has a small range of activity, the cockpit domain controller determines that the fish school is less active and automatically adjusts the light intensity and color of the DLP projection lights, using warm colors and enhancing the light intensity to attract fish. At the same time, the cockpit domain controller synchronously sends the processed fish school information and system status data to the mobile phone APP.

[0055] DLP projection headlight 1: After receiving the control signal from the cockpit domain controller 2, it irradiates the water surface with a specific wavelength of light through high-precision DLP projection technology. According to the sensor data and control instructions, the shape of the light spot is dynamically adjusted, such as adjusting the light spot to a circular shape to cover the fish gathering area, or adjusting it to a long strip shape to guide the fish to move to the fishing spot; adjusting the intensity of the light spot to adjust the intensity according to the distance and activity of the fish school; adjusting the color of the light spot to switch according to the preference of different fish species for light color. In addition, it can also project simulated ripples, moonlight and other effects to make the lighting more natural and enhance the attraction to fish.

[0056] Underwater sensor module 3: The sonar detector continuously emits sound waves and receives reflected waves. By analyzing the time, intensity and other information of the reflected waves, it detects the location, quantity and movement trend of the fish school, and transmits these data to the cockpit domain controller in real time. The temperature sensor monitors the underwater temperature in real time and sends the temperature data to the cockpit domain controller in the form of a digital signal. The light sensor continuously senses the underwater light intensity and also feeds the data back to the cockpit domain controller, providing comprehensive data support for the system to dynamically adjust the projection mode.

[0057] In the above embodiment, the fusion of DLP projection technology and sensor data is used to realize dynamic adjustment of the light source, which can intelligently guide the fish school according to different underwater environments and fish school conditions, effectively improving fishing efficiency; through the mobile phone APP, the user can remotely control the DLP projection car lights without operating in the car, which greatly improves the convenience of use. At the same time, it receives underwater fish information in real time, allowing users to grasp the fishing situation at any time and make more reasonable decisions; DLP headlights can project light sources of specific wavelengths and optimize lighting modes. According to the habits and lighting preferences of different fish species, it adjusts the lighting conditions that are most suitable for attracting target fish, making fish more easily attracted and increasing the success rate of fishing; compared with traditional strong light lighting methods, this system can automatically adjust the brightness and color of the light source according to the underwater environment, avoid excessive lighting from interfering with the aquatic ecosystem, and protect the ecological balance of the water area; the sensor module can monitor the distribution of fish and the underwater environment in real time, and realize linkage with the cockpit domain controller, so that the system can be accurately controlled according to real-time data to ensure that the lighting effect is always in the best state; the light spot shape can be flexibly adjusted according to different environmental requirements and fishing scenes, such as simulating natural light such as water waves and moonlight, to improve adaptability to different types of fish and meet diverse fishing needs.

[0058] It is worth mentioning that all modules involved in this embodiment are logical units. In practical applications, a logical unit can be a physical unit, a part of a physical unit, or a combination of multiple physical units. In addition, in order to highlight the innovative part of the present invention, this embodiment does not introduce units that are not closely related to solving the technical problem proposed by the present invention, but this does not mean that there are no other units in this embodiment.
