[0002] In the operation of grain terminals, illumination is a key factor affecting operating efficiency, personnel safety, and energy consumption costs. Traditional lighting methods cannot flexibly respond to changes in the natural environment, so there are problems such as over-illumination when there is sufficient light and under-illumination when there is insufficient light, which not only wastes energy but also fails to achieve the best lighting effect for the terminal.

[0003] Therefore, it is necessary to propose a method for intelligently controlling the lighting of grain terminals based on natural light illumination, which can capture and analyze the illumination information of different areas of the grain terminal in real time, and automatically adjust the brightness and distribution of lighting equipment based on the external environment to ensure that sufficient and energy-saving lighting conditions can be provided for grain terminal operations in any weather or at any time.

[0024] See also Figure 1 The present invention optimizes the existing lighting control method and system of grain terminals, obtains the lighting information of different grain stacking positions, and applies the illumination prediction model to analyze the natural lighting conditions of different positions, and intelligently adjusts the lighting equipment of different stacking positions based on the natural lighting conditions, ensuring that the grain terminal has a suitable and efficient lighting environment under different times and natural conditions. The present invention provides an intelligent control method for grain terminal lighting, and the above-mentioned intelligent control method for grain terminal lighting includes the following steps:

[0025] S1. Establish a grain storage area marking model based on the grain terminal, and obtain the center coordinate information of different grain stacking locations through the grain storage area marking model. The specific implementation steps and contents are as follows;

[0026] First, conduct a comprehensive field survey of the grain terminal and record the layout of the grain terminal storage area in detail, including but not limited to the distribution of grain yards, warehouse types and sizes, and other key information. At the same time, carefully distinguish and record the types of stored grain and their unique stacking methods. The above actual construction information of the grain terminal will help the subsequent grain storage area marking task.

[0027] Subsequently, a grain terminal yard information database is constructed by combining the field survey information and relevant data from the grain terminal storage management system. At the same time, geographic information system (GIS) technology can be used to accurately mark the area, stacking requirements, and yard conditions of each grain storage area on the digital platform based on the actual construction of the grain terminal. Through real-time data access and processing technology, the timeliness and accuracy of the storage area marking results can be ensured, and the dynamic update of the grain stacking location can be achieved. Finally, integrating all the above information into the grain stacking management module will help realize the digital and visual management of the grain terminal.

[0028] In the grain stack management module, point translation method, spatial coordinate rotation method and world coordinate system are introduced, and the grain storage area marking model is established by combining grain terminal, point translation method, spatial coordinate rotation method and world coordinate system. The specific contents are as follows;

[0029] In order to determine the actual location of different grain piles, the actual lighting information is obtained and analyzed. Combined with the on-site survey information of the grain terminal, each grain pile on the grain terminal is marked, and its geographical location coordinates and relative position relationship are recorded, which will help with the subsequent accurate monitoring and analysis of different grain piles.

[0030] The embodiment adopts a grain stack coordinate calibration strategy based on the regional center. In order to ensure the accuracy of each grain stacking position on the grain terminal, a calibration strategy based on the regional center coordinates is implemented. In an optional embodiment, based on the information in the grain stack management module, the center position of different grain stack areas is identified and determined. The above center position represents the geometric center or core point of the different stack areas. Subsequently, the location information of different grain stacks is obtained around the center position through high-precision measurement methods such as GPS positioning, laser ranging, etc.

[0031] On the basis of obtaining the center coordinates of different stacking areas, the coordinate information of the stacking areas is further improved, including recording the boundary range, shape characteristics, and relative position relationship of different grain stacking areas with respect to other stacking areas or fixed reference objects. Based on this, a detailed and accurate grain stacking area coordinate information database can be constructed, providing a data basis for the subsequent analysis of the lighting conditions at the wharf.

[0032] In addition, in order to ensure the accuracy and timeliness of coordinate information, the grain stack management module will regularly review and update the center coordinates of different grain stacks, including but not limited to using modern technical means to conduct fast and efficient on-site surveys, and monitoring possible minor changes in the stack position through data analysis. Relevant measures can ensure that the location information of each grain stack in the grain terminal is always kept in the most accurate state.

[0033] Since the on-site survey images of grain terminals are mostly obtained based on the pinhole imaging model in the projection model, the principle of lens imaging can be found in Figure 2 ,in Represents the focal length of the lens, Indicates the actual distance value of the center of the grain stacking position. Indicates the image distance value of the center of the grain stacking position.

[0034] Based on the schematic diagram, the ideal pinhole imaging model satisfies the following relationship:

[0035]

[0036] in, Represents the focal length of the lens, Indicates the actual distance value of the center of the grain stacking position. Indicates the image distance value of the center of the grain stacking position. When the grain is stacked far away from the lens, that is, when the object distance is much greater than the focal length of the lens, the refraction of the lens on the light is mainly concentrated near its focus, so that the light from the grain stacking position is almost parallel to the imaging plane or image plane after passing through the lens, and forms a clear image at a position close to the focal length. Since the image distance is very close to the focal length in this case, the imaging process of the lens can be simplified to an idealized model, and the light is directly projected onto the imaging plane through the small hole to form an inverted image of the target object.

[0037] In order to accurately determine the location of each grain pile in the grain terminal, the embodiment uses the grain pile coordinate information database and firstly introduces a point translation method to adjust the geographical coordinates of different grain piles. The above method is based on the translation transformation principle of the coordinate system, that is, on the basis of the original coordinate vector, a specific translation vector is added to realize the position movement of the point, and the target object is moved a certain distance along the specified direction in two-dimensional or three-dimensional space.

[0038] In the actual operation process, multiple coordinate axes are translated, and the corresponding translation vectors can be added to the coordinate components of each axis in any order. Since the translation transformation satisfies the commutative law and the associative law, the order of translation does not affect the final transformation result. Whether the translation is performed on the X-axis first, then on the Y-axis, or the Y-axis translation is performed first and then on the X-axis, the final position coordinates of the pile will be the same. In addition, the position of different grain piles in the coordinate system can be flexibly adjusted to ensure that it is highly consistent with the actual position. At the same time, the point translation method is conducive to analyzing the relative position relationship between different grain piles, providing data support for subsequent natural lighting analysis.

[0039] In an optional embodiment, the coordinates of the center position of any grain pile are:

[0040]

[0041] in, represents the center coordinates of any grain stacking location, The X-axis represents the center coordinate of any grain stacking location. The Y axis represents the center coordinate of any grain stacking location. Represents the Z-axis coordinate of the center of any grain stacking location.

[0042] According to the point translation method, the coordinate translation vector needs to satisfy the following relationship: , so the center coordinates of the grain stacking position after point translation are:

[0043]

[0044] in, Indicates the center coordinates of the grain stacking position after translation, The X-axis represents the center coordinate of any grain stacking location. The Y axis represents the center coordinate of the grain stacking position after translation. Represents the Z-axis coordinate of the center of the grain stacking position after translation.

[0045] Then, the spatial coordinate rotation method is introduced, that is, the combined application of the rotation transformation of the coordinate system and the rotation matrix. In order to rotate the spatial coordinate system, a rotation matrix is ​​used, and the column vector of the rotation matrix represents the axis vectors of the rotated coordinate system in the original coordinate system. Combining the spatial coordinate rotation method and the rotation matrix, the rotation transformation between coordinate systems can be flexibly realized, providing technical support for geometric calculations, graphics processing, and machine navigation in space.

[0046] Based on the center coordinates of the grain stacking position after translation, the center coordinate position of any grain stacking is rotated. In the embodiment, the rotation matrix is ​​S, and the center coordinate position after rotation is as follows:

[0047]

[0048] in, Indicates the center coordinates of the grain stacking position after rotation, represents the rotation matrix, Represents the X-axis of the center coordinate of any grain stacking position after translation, The Y axis represents the center coordinate of the grain stacking position after translation. Represents the Z-axis coordinate of the center of the grain stacking position after translation.

[0049] Finally, the world coordinate system is introduced. In the embodiment, the world coordinate system is used to rotate around the X-axis, Y-axis, and Z-axis respectively. , then the corresponding rotation matrices are , the rotation matrix of different grain stacking positions satisfies the following relationship:

[0050]

[0051] in, represents the rotation matrix of the world coordinate system, represents the rotation matrix of the X axis, represents the rotation matrix of the Y axis, Represents the rotation matrix about the Z axis.

[0052] Based on the above point translation method, space coordinate rotation method and world coordinate system, the grain storage area marking model in the embodiment satisfies the following relationship:

[0053]

[0054] in, The X-axis represents the position of any grain stack after optimization. The Y axis represents the position of any grain stack after optimization. It represents the Z axis of any grain stacking position after optimization. represents the rotation matrix of the X axis, represents the rotation matrix of the Y axis, represents the rotation matrix of the Z axis, Represents the X-axis of the center coordinate of any grain stacking position after translation, The Y axis represents the center coordinate of the grain stacking position after translation. Represents the Z axis of the center coordinate of the grain stacking position after translation, Indicates the influence weight of the camera's external parameters on the X-axis. Indicates the influence weight of the camera's external parameters on the Y axis. Indicates the influence weight of the camera's external parameters on the Z axis. Represents the distortion coefficient of position imaging.

[0055] In this embodiment, the grain storage area marking model established by the point translation and spatial coordinate rotation method can accurately determine the specific locations of different grain storage areas, which is helpful for precise layout design of the lighting system, ensuring that each work area can obtain the appropriate lighting intensity, avoiding energy waste while ensuring the safety of terminal operations.

[0056] Furthermore, the method for locating different grain piles based on the grain pile management module in the present embodiment is merely an optional condition of the present invention. In other embodiments, the grain pile positioning method can be flexibly adjusted according to the actual situation of the grain terminal and the lighting requirements of the terminal. Different grain terminals have different layouts, scales, operating processes and other characteristics, and the requirements for lighting and pile management may also be different. Flexibly adjusting the grain pile positioning method according to the specific circumstances can help optimize the terminal lighting resources and maximize the use of energy.

[0057] S2. Setting a grain yard lighting environment intelligent monitoring module according to the center coordinate information, and obtaining lighting environment information of different grain stacking positions through the grain yard lighting environment intelligent monitoring module. The specific implementation steps and contents are as follows;

[0058] The intelligent control system of grain terminal lighting is equipped with a grain yard lighting environment intelligent monitoring module. The installation of the grain yard lighting environment intelligent monitoring module is debugged and set according to the center coordinate information of the above-mentioned different grain stacks. The specific contents are as follows;

[0059] The intelligent monitoring module for the lighting environment of the grain yard configured in the intelligent control system of the grain terminal lighting can improve the lighting efficiency of the grain terminal, ensure operational safety and optimize energy utilization. In the embodiment, based on the central coordinate information of different grain stacks, the installation status of the intelligent monitoring equipment in different stacking areas is debugged and set, which can ensure the accuracy and effectiveness of the light monitoring data and provide a reliable basis for the intelligent control method of the grain terminal lighting.

[0060] First, the monitoring equipment selection and layout planning should be carried out. According to the actual environment and historical data of different grain storage locations, such as light intensity range, temperature and humidity conditions, dust concentration, etc., appropriate intelligent monitoring equipment for light environment should be selected. The above monitoring equipment should have the characteristics of high precision, high stability, and strong anti-interference ability.

[0061] Based on the central coordinate information of the grain stacking location at the terminal, the installation location of the monitoring equipment is reasonably planned. In the embodiment, the monitoring equipment should be installed at key locations that can fully reflect the lighting environment of the yard, such as the top of the stack, the stack channel, the edge of the yard, etc. At the same time, the spacing and coverage between different monitoring devices must also be considered to ensure that the lighting environment of the entire yard can be effectively monitored.

[0062] Then, the installation and debugging of the lighting environment intelligent monitoring equipment is carried out. According to the layout plan of the grain terminal, the intelligent monitoring equipment is installed at the predetermined location. During the installation process, attention should be paid to factors such as firm fixing, correct wiring, and avoiding obstruction to ensure that the intelligent monitoring equipment can work normally.

[0063] After the installation is completed, the intelligent monitoring equipment in the grain yard lighting environment intelligent monitoring module is debugged. First, check whether the basic functions of the intelligent monitoring equipment are normal, such as data collection and transmission. Then, according to the central coordinate information of the grain stacking position at the terminal, calibrate and adjust the monitoring range of the monitoring module to ensure that the monitoring data can accurately monitor and reflect the lighting environment information of different grain stacking positions. In addition, the intelligent monitoring equipment needs to be tested for performance and stability to ensure that it can operate stably in the long term.

[0064] In the embodiment, the lighting environment information of different grain stacking locations is obtained through the grain yard lighting environment intelligent monitoring module, and the specific content is as follows;

[0065] First, ensure that all grain yard lighting environment intelligent monitoring modules have been correctly installed and powered on, start the module to enter the working state, and set the lighting environment parameters that need to be monitored for each monitoring module according to the actual needs of the grain terminal, such as light intensity, light uniformity, color temperature, etc. At the same time, calibrate the monitoring equipment of the grain terminal to ensure the accuracy of the monitoring information.

[0066] The intelligent monitoring equipment starts to collect the lighting environment data in their respective responsible areas in real time, including but not limited to the light intensity value, timestamp, irradiation range, etc. The grain yard lighting environment intelligent monitoring module transmits the collected data to the intelligent control system or cloud server of the grain terminal lighting via wireless methods such as Wi-Fi, LoRa, NB-IoT, etc. or wired methods such as Ethernet, RS485, etc. The integrity and security of the lighting environment information must be ensured during the transmission process.

[0067] In addition, the grain yard lighting environment intelligent monitoring module can transmit and process the lighting environment information of different grain stacking locations. In an optional embodiment, the grain yard lighting environment intelligent monitoring module collects data packets from various monitoring devices, parses and stores them, and then cleans the lighting environment information in the module, removes abnormal values, duplicate values ​​and other pre-processing to ensure the accuracy of the grain stacking location analysis results, and finally integrates the cleaned lighting environment information according to dimensions such as time and location to form a complete lighting environment data set.

[0068] Furthermore, the method for obtaining lighting environment information of different grain stacking locations in the present embodiment is only an optional condition of the present invention. In one or some other embodiments, the method for obtaining lighting environment information can be optimized according to the specific conditions of the terminal operation and the lighting needs of the terminal. Different terminals have significantly different lighting needs due to factors such as geographical location, climatic conditions, and types of stored grain. The lighting environment information can be used to more accurately control the switching, brightness and other parameters of lighting equipment, thereby avoiding unnecessary energy waste, which helps to improve the energy efficiency of terminal operations and reduce operating costs.

[0069] S3. Based on the above-mentioned illumination environment information and center coordinate information, a grain stacking location illumination prediction mechanism is constructed, and the comprehensive illumination conditions of different grain stacking locations are obtained according to the grain stacking location illumination prediction mechanism. The specific implementation steps and contents are as follows:

[0070] A grain stacking location illumination prediction mechanism is constructed based on the lighting environment information and center coordinate information of different grain stacking locations. The above-mentioned grain stacking location illumination prediction mechanism mainly includes a direct sunlight analysis model for the grain stacking location and a reflected light illumination analysis model for the grain stacking location.

[0071] Relevant information needed to predict illumination is extracted from the lighting environment information, including but not limited to solar altitude angle, azimuth angle, cloud cover, atmospheric transparency, etc.; information based on the center coordinates of different grain stacking locations helps to analyze and calculate the relative relationship between the sun's position and different grain stacking locations at the dock. At the same time, the geometric parameters of the grain stacking locations need to be collected, such as stacking height, width, length, shape, etc. The above parameters will also affect the receiving area and angle of sunlight, thereby making the lighting conditions and lighting equipment different for different grain stacking locations.

[0072] Based on the above-mentioned lighting environment information and center coordinate information, a direct sunlight analysis model for the grain stacking location is established, and its specific contents are as follows:

[0073] The above-mentioned direct sunlight analysis model for the grain stacking location satisfies the following relationship:

[0074]

[0075] in, Indicates the illumination of direct sunlight at different grain stacking locations. represents the atmospheric attenuation coefficient, It represents the average reflection coefficient of the reflective surface at different grain stacking locations. Indicates the direct sunlight brightness at different grain stacking locations. Indicates the comprehensive light transmittance coefficient of different grain stacking positions, Indicates the solar altitude angle at different grain stacking locations.

[0076] The illumination of direct sunlight at different grain stacking locations indicates the direct sunlight energy received by the corresponding area at different grain stacking locations.

[0077] The atmospheric attenuation coefficient reflects the degree to which sunlight is weakened when passing through the atmosphere due to scattering, absorption and other effects. It is usually related to factors such as cloud cover, atmospheric composition, and altitude. The atmospheric attenuation coefficient will change with weather conditions.

[0078] The average reflection coefficient of the reflective surface at different grain stacking locations can describe the reflectivity of the surface materials at different grain stacking locations to sunlight. Different materials such as metal, plastic, soil, etc. have different reflection coefficients. It mainly depends on the properties of the incident light such as wavelength, intensity, angle, etc., the properties of the reflecting surface such as material, roughness, color, etc., and the specific conditions of the light information measurement. The reflection coefficient refers to the ratio of the intensity of the reflected light on the surface to the intensity of the incident light when light or other forms of radiation are projected onto an object. The above ratio can be affected by many factors, so in practical applications, it is necessary to measure the reflection coefficients of multiple points and then calculate the average value to obtain the average reflection coefficient.

[0079] The direct sunlight brightness at different grain stacking locations refers to the brightness of the grain stacking location when the sun directly shines on the grain stacking location without the influence of atmospheric attenuation and reflectors. It is usually related to the altitude angle and azimuth angle of the sun and the brightness of the sun itself. For the solar altitude angles at different stacking locations in the embodiment, please refer to Figure 3 , Indicates the direct sunlight brightness at different grain stacking locations. represents the solar altitude angle at different grain stacking locations, and PM represents the ground plane at different grain stacking locations.

[0080] The comprehensive light transmittance coefficient of different grain stacking positions also comprehensively considers the influence of various factors on light transmission, such as the internal structure of the stacked objects, the light transmittance of the materials, and the obstructions. The light transmittance coefficient can be used to evaluate the shading effect of different stacking positions. It is the ratio of the light spot area formed by direct sunlight on the calculation plane with shading structure to the light spot area formed by direct sunlight on the standard calculation plane without shading structure.

[0081] The comprehensive light transmittance coefficients at different grain stacking positions in the embodiment satisfy the following relationship:

[0082]

[0083] in, Indicates the comprehensive transmittance coefficient of different stacking positions, Indicates the spot area on the calculation plane with sunshade structure at different stacking positions, Indicates the calculation of plane area at different stacking positions.

[0084] The solar altitude angle at different grain stacking locations refers to the angle between the sun's rays and the ground, which determines the angle and intensity of the sun's rays hitting the dock ground. The transmittance coefficient will change with the solar altitude angle and azimuth. Therefore, in this embodiment, the roof shading conditions throughout the year are analyzed, and the transmittance coefficient at noon on the 20th of each month is selected for measurement.

[0085] Based on the above-mentioned lighting environment information and center coordinate information, a reflected light illumination analysis model for the grain stacking location is established, and its specific contents are as follows:

[0086] In the embodiment, relevant parameter information is obtained based on the lighting environment information, including but not limited to the intensity of direct sunlight, sky brightness, reflective characteristics of the surrounding environment, etc.; according to the coordinates of the center position of the grain pile, its position relative to the surrounding reflection sources is determined. In addition, it is also necessary to combine the geometric information of different positions, such as the position, height, shape, etc. of the piled objects, which helps to accurately calculate the direction and intensity of the reflected light.

[0087] It is also possible to further determine the factors that cause different grain stacking areas to significantly reflect the light irradiated to the grain stacking location, including but not limited to the ground, surrounding buildings, other stacked objects, etc.

[0088] The above-mentioned reflected light illumination analysis model at the grain stacking location satisfies the following relationship:

[0089]

[0090] in, Indicates the reflected light intensity at different grain stacking locations. Indicates the comprehensive light transmittance coefficient of different grain stacking positions, Indicates the height of different grain stacking locations, The average characteristic index of the reflective surface at different grain stacking locations is represented by It indicates the illumination of the horizontal surface of different grain stacking positions by direct sunlight. It represents the average reflection coefficient of the reflective surface at different grain stacking locations. Indicates the illumination of sky light on different grain stacking locations, Indicates the area of ​​different grain stacking locations.

[0091] The above-mentioned reflected light illumination analysis model for the grain stacking location takes into account a variety of factors, including comprehensive transmittance, height, characteristics of the reflector surface, direct sunlight illumination, reflection coefficient and sky illumination.

[0092] Among them, the reflected light illuminance at different grain stacking locations refers to the light intensity that is redistributed to various points in the grain stacking area after the light source in a specific grain stacking area shines on the surface of the grain stacking object and is reflected.

[0093] The average characteristic index of the reflective surface at different grain stacking positions is related to the parameters such as the surface roughness and shape of the grain stacking positions, which ultimately affect the scattering and reflection of light.

[0094] The illumination of direct sunlight on the horizontal plane of different grain stacking positions refers to the light intensity generated by the sunlight directly shining on the horizontal plane where the grain is stacked, without interference from other obstructions, accumulations or reflectors. This illumination can be the distribution of solar radiation energy per unit area on the horizontal plane, and can then be expressed by the luminous flux per unit area of ​​the stacking position.

[0095] The illumination of skylight on different grain stacking locations refers to the light intensity generated by the scattered or reflected light from the sky, not the direct sunlight, shining on the grain stacking area. The illumination of skylight on different grain stacking locations is affected by many factors, including but not limited to geographical location, season, time, weather conditions, reflective characteristics of the surrounding environment, etc. Since skylight is scattered light, its directionality is relatively weak, so it can illuminate a wider area and produce more uniform illumination on the grain stacking location.

[0096] In the embodiment, the area of ​​different grain stacking positions can be quickly obtained based on the central coordinate information of different grain stacking positions. The central coordinate information can be used to quickly locate the area requiring lighting, collect information, and monitor the actual situation, which significantly improves work efficiency. It can further realize the automation and intelligent control of grain terminal lighting and improve overall operational efficiency.

[0097] Based on the above-mentioned grain stacking location sunlight direct light analysis model and grain stacking location reflected light illumination analysis model, a grain stacking location illumination prediction mechanism is constructed, and its specific contents are as follows:

[0098] Based on the direct sunlight analysis model of grain stacking position, the direct sunlight illumination of different grain stacking positions is obtained;

[0099] The direct sunlight analysis model for grain stacking locations takes into account factors such as the position of the sun, atmospheric conditions, geographic location, season and time. By detecting and inputting the above parameters into the direct sunlight analysis model through the grain yard lighting environment intelligent monitoring module, the illumination of direct sunlight on the horizontal plane or specific inclined plane of different grain stacking locations at different time points can be calculated. Based on this, the direct sunlight illumination data and actual environmental conditions of different grain stacking locations at different time periods can be obtained.

[0100] Based on the reflected light illumination analysis model of grain stacking position, the reflected light illumination of different grain stacking positions is obtained;

[0101] Next, based on the grain stacking location reflected light illumination analysis model, the reflective characteristics of the grain stacking surface, such as reflection coefficient, surface roughness, illumination of direct sunlight, illumination of sky light, and the geometric shape and layout of the stacking objects, are considered. Incorporating the relevant factors monitored by the grain yard lighting environment intelligent monitoring module into the model can simulate the reflection process of light on the surface of the grain stacking object, and calculate the illumination generated by the reflection effect at different grain stacking locations, thereby obtaining the reflected light illumination data at different grain stacking locations in the wharf.

[0102] Obtaining the illumination of different grain stacking positions by external reflected light according to the lighting environment information and the center coordinate information;

[0103] Finally, in order to more comprehensively understand the lighting environment of different grain stacking positions at the wharf, it is also necessary to consider the lighting effect of external reflected light on different grain stacking positions at the wharf. In this embodiment, the reflected light from surrounding buildings, ground, stacked objects or other objects is mainly analyzed. In order to analyze the illumination of different grain stacking positions by external reflected light, based on the lighting environment information of different grain stacking positions, such as the reflection characteristics of the surrounding environment, the position of the light source, and the central coordinate information of each grain stacking position, the propagation and reflection process of external light in the environment can be simulated, and the illumination contribution of external reflected light to different grain stacking positions can be estimated, and then the total illumination data under the influence of direct sunlight, reflected light and external reflected light at different grain stacking positions can be comprehensively analyzed, so that the illumination of different stacking positions by external reflected light and the illumination of different stacking positions by sky light can be obtained.

[0104] According to the lighting environment information and the central coordinate information of the grain stacking location, the illumination of different grain stacking locations under natural conditions in different seasons or at different times of the wharf can be calculated, and the comprehensive lighting conditions of different grain stacking locations can be comprehensively analyzed by combining multi-dimensional factors such as direct sunlight illumination, reflected light illumination, external reflected light illumination, and sky illumination. Using the lighting data of different grain stacking locations and the specific location information of grain stacking, we can deeply understand and evaluate the lighting conditions of different grain stacking areas. Due to the linear superposition property of illumination, in this embodiment, the total illumination of the external natural environment on different stacking locations needs to satisfy the following relationship:

[0105]

[0106] in, Indicates the total illumination of natural lighting at different stacking positions, Indicates the illumination of direct sunlight at different stacking positions. Indicates the reflected light intensity at different stacking positions. Indicates the illumination of external reflected light at different stacking positions, Indicates the illumination of sky light at different stacking positions.

[0107] Furthermore, in the present embodiment, the method for analyzing the comprehensive lighting conditions of different grain stacking locations is only an optional condition of the present embodiment. In one or some other embodiments, the method for analyzing the comprehensive lighting conditions may be adjusted according to the actual lighting needs and lighting objectives of the wharf. Comprehensive consideration of multiple lighting sources can more comprehensively reflect the lighting conditions of the grain stacking locations, help discover areas where there may be insufficient or excessive lighting, and provide a strong basis for subsequent lighting regulation.

[0108] S4. Combine the comprehensive lighting conditions, lighting environment information and center coordinate information to adjust and control the lighting equipment at different grain stacking locations to achieve intelligent adjustment and control of grain terminal lighting. The specific implementation steps and contents are as follows:

[0109] A grain stack lighting control module is configured in the intelligent control system of grain terminal lighting.

[0110] The above-mentioned grain stack lighting control module integrates advanced data receiving, processing and decision-making technologies, and is capable of receiving and analyzing in real time the comprehensive lighting information, lighting environment parameters and center coordinate information from each grain stacking location.

[0111] By comprehensively using the above information, the grain stack lighting control module first locates the grain stack according to the central coordinate data, and then compares and analyzes the historical data and pre-lighting requirements of different grain stacks with the comprehensive lighting information and lighting environment parameters of different grain stacking locations based on the positioning results, intelligently evaluates the lighting conditions of different grain stacking areas, and formulates the optimal lighting control strategy accordingly. The above strategies include but are not limited to adjusting the brightness, color temperature, switch status of lighting equipment, and optimizing lighting layout, so as to ensure that different grain stacking areas can obtain lighting effects that meet operational needs and are energy-saving and environmentally friendly.

[0112] In addition, the grain stack lighting control module also has powerful adaptive capabilities and dynamic optimization functions. It can dynamically adjust the terminal lighting strategy according to changes in external lighting conditions such as sunrise and sunset, weather changes, etc., to meet the lighting needs of different locations. At the same time, it is necessary to continuously monitor and evaluate the lighting effect, and then continuously optimize the control strategy to ensure the long-term and efficient operation of the lighting system, providing strong technical support for the intelligentization, automation and energy saving of grain terminal lighting methods and systems.

[0113] The grain stack lighting control module is integrated and configured in the intelligent control system of grain terminal lighting. As the core unit of the intelligent control system, the module integrates advanced data processing and decision-making algorithms to provide technical support for the precise control of grain terminal lighting. The grain stack lighting control module can perform dynamic optimization and feedback adjustment. The system can continuously monitor the control effect and dynamically optimize and adjust according to actual lighting changes and operational requirements, forming a closed-loop control mechanism for the grain terminal lighting intelligent control system, and continuously improving the intelligence level and actual application energy efficiency of the lighting system.

[0114] Through the above steps, the grain terminal lighting system of this embodiment can achieve a high degree of intelligence, automation and energy saving, which not only significantly improves the operation efficiency and safety of the terminal, but also effectively reduces energy consumption and operating costs, and contributes to the green and sustainable development of the grain terminal. At the same time, with the continuous advancement of technologies such as the Internet of Things, big data, and artificial intelligence, the intelligent control system of grain terminal lighting will have a broader application prospect and development space in the future.

[0115] In an optional embodiment, if there are three grain stacking areas A, B, and C waiting for lighting adjustment in the grain terminal, each area has different requirements for lighting conditions according to the type of grain stored and the operational needs. First, the grain stack lighting control module in the intelligent control system will collect the comprehensive lighting information of the above three areas based on the central coordinate information of the grain stacking positions A, B, and C, including but not limited to the sky light illumination, direct sunlight illumination, and reflected light illumination of the surrounding environment output by the grain stack illumination information analysis module.

[0116] At the same time, the control module will also receive the actual lighting environment information of different grain storage areas output by the grain yard lighting environment intelligent monitoring module, and judge whether it is day or night according to the current time. The season will affect the duration and intensity of sunshine at the grain terminal, and the weather conditions are sunny, cloudy or rainy. The above actual lighting environment information helps to judge the intensity and changing trend of natural light.

[0117] Based on the above information, the control module of the intelligent control system of the grain terminal lighting will perform the following intelligent control:

[0118] If area A is located at the edge of the dock and it is a clear day with high direct sunlight illumination, and the comprehensive lighting conditions show that the natural lighting in the grain stacking area meets the operational needs, then the control module will automatically reduce the brightness of the artificial lighting in the area, and can even control the shutdown of some lighting equipment to save energy at the dock.

[0119] If area B is located inside the dock and there are many obstructions around it, natural light is insufficient. Even during the day, additional lighting may be needed to achieve the preset lighting conditions and ensure the safety of the grain stacking operations. At this time, the control module will adjust the lighting equipment in this area based on the comprehensive lighting conditions and lighting environment information. It can appropriately increase the brightness of artificial lighting in area B, and accurately adjust the illumination range and angle of the lighting equipment based on the center coordinate information to ensure that the light evenly covers the entire work area.

[0120] If the C operation area is at night, then no matter how the natural light changes, external lighting equipment is needed to ensure the lighting conditions of the work area. The control module will automatically turn on and adjust the relevant lighting equipment in area C to the best working state according to the preset night lighting standards and center coordinate information to ensure the lighting conditions of the above operation area, thereby ensuring the smooth progress of the terminal work.

[0121] Based on the above embodiments, it can be seen that the grain terminal can not only provide a suitable lighting environment according to the specific needs of different grain stacking locations, but also effectively save energy, reduce terminal operating costs, and realize green, efficient and intelligent operation of the grain terminal.

[0122] In the embodiment, the position coordinates of different grain stacking areas are marked and set, and the grain stacking areas at the terminal are divided and located, which helps to customize differentiated lighting strategies to better adapt to the lighting needs of different grain stacking areas; then, based on the central coordinate information of the grain stacking position at the terminal, the light sensor technology and data analysis algorithm are deployed to improve the accuracy and real-time performance of light information collection, thereby further improving the accuracy and efficiency of lighting control results; then, combined with the operating procedures and actual changes in the grain stacking areas at the terminal, the operating parameters of the lighting system are dynamically adjusted to ensure that the lighting effect is highly matched with the operating requirements; this system takes into account the goals of energy management and energy conservation and emission reduction, optimizes the energy consumption management strategy of the lighting system, and realizes a green and sustainable lighting solution.

[0123] Furthermore, in the present embodiment, the intelligent control method of grain terminal lighting is only an optional condition of the present embodiment. In one or some other embodiments, the intelligent control method of lighting can be optimized according to the actual stacking situation at the terminal and the actual lighting needs of the region. The intelligent control method is not fixed. In order to make the system highly flexible and scalable, in actual applications, the intelligent control method of lighting is deeply optimized and adjusted according to the actual stacking situation at the grain terminal, the specific lighting needs of the region and the latest trends in technological development.
