Description

Technical Field

[0001] The present invention relates to the technical field of agricultural intelligent lighting supplementation, and in particular to an intelligent spectrum control lighting supplementation system for rubber forests. Background Art

[0002] As an important tropical cash crop, the latex yield and quality of rubber trees are directly affected by light conditions. Traditional rubber plantations rely on natural sunlight, but tropical regions experience frequent seasonal rainy and foggy weather, resulting in insufficient effective photosynthetic radiation. Furthermore, rubber trees exhibit significant differences in their spectral requirements during different phenological stages (seedling, growing, and tapping). To ensure sustained high yields of rubber trees, artificial lighting technology is required to optimize their photosynthetic environment. Current lighting systems mostly use fixed-spectrum lighting devices, which are difficult to dynamically adapt to the physiological needs of rubber trees and complex environmental changes, thus restricting the improvement of latex synthesis efficiency.

[0003] Existing supplementary lighting systems generally have the following defects: they use a single white light or a fixed red and blue light ratio, and are unable to dynamically adjust the spectral composition according to the phenological stage of the rubber tree (for example, far-red light is needed to promote latex differentiation during the tapping period); they lack the ability to collaboratively perceive the multi-dimensional environmental parameters of the rubber forest (light intensity, temperature and humidity, soil moisture, and leaf reflectance spectrum), and the supplementary lighting strategy does not match the real-time environment; the coverage range of the supplementary lighting device is fixed, making it difficult to adapt to the planting layout of the rubber forest with differentiated crown diameters, which can easily cause energy waste or illumination blind spots; they over-rely on cloud control, are unable to make independent decisions when communication is interrupted, and lack visual interactive means for field management. Summary of the Invention

[0004] The present invention solves the problems of low lighting efficiency, high energy consumption, and difficulty in meeting the precise production requirements of rubber plantations in the existing lighting systems, and provides an intelligent spectrum-controlled lighting system for rubber plantations.

[0005] The technical solution adopted by the present invention is: a rubber forest intelligent spectrum control and supplementary lighting system, including an environmental perception module, a spectrum adjustable supplementary lighting module, a central control module, a power supply and communication module, a cloud data platform, and a mobile inspection terminal.

[0006] The environmental perception module is used to collect rubber forest growth environment parameters in real time; the spectrally adjustable fill light module includes multiple groups of independently controllable LED light source units, each unit can emit spectra of different wavelengths; the central control module connects the environmental perception module and the spectrally adjustable fill light module, and generates a fill light strategy based on environmental parameters and a preset rubber tree spectral demand model; the power supply and communication module supplies power to the system and supports remote data transmission; the cloud data platform receives data uploaded by the central control module, and optimizes the spectral demand model through machine learning before sending it to each terminal; the mobile inspection terminal receives system alarm information through wireless communication and supports manual override of the fill light strategy.

[0007] As a further improvement of the present invention, the environmental perception module includes a light intensity sensor, a multi-spectral sensor, a temperature and humidity sensor, and a soil moisture sensor.

[0008] As a further improvement of the present invention, the multispectral sensor includes a dual-channel detector of visible light (400-700nm) and near infrared (700-1000nm), which monitors the chlorophyll reflectance characteristics of rubber trees in real time with a spectral resolution of 0.5-2nm.

[0009] As a further improvement of the present invention, the LED light source unit of the spectrally adjustable fill light module includes four types of wavelength band light sources: red light (630-660nm), blue light (450-470nm), far red light (730-750nm) and ultraviolet light (380-400nm), and the brightness of each band is independently adjustable.

[0010] As a further improvement of the present invention, the spectrum-adjustable fill light module adopts a modular array layout, a single fill light unit covers an area of ​​≤4 m2, and the spacing between units is adaptively adjusted according to the crown diameter of the rubber tree.

[0011] As a further improvement of the present invention, the central control module has a built-in rubber tree phenological period recognition algorithm, which identifies whether the rubber tree is in the seedling stage, growth stage, and tapping stage based on environmental data and matches the corresponding spectral formula.

[0012] As a further improvement of the present invention, for rubber trees during the tapping period, the proportion of far-infrared light band in the spectral formula is increased to 30%-40%, the proportion of blue light band is reduced to 10%-15%, and the daily lighting period is limited to 2 hours before to 4 hours after the tapping operation.

[0013] As a further improvement of the present invention, the central control module is configured with a local policy cache unit, which automatically switches to a verified fill light policy executed within the last 72 hours when communication is interrupted, and records an abnormal status log.

[0014] As a further improvement of the present invention, the central control module integrates an energy-saving control strategy, which automatically turns off the fill light module when the ambient light intensity is ≥8000 lux, and starts the red light band enhancement mode (red light intensity is increased to 120%-150% of the normal value) in continuous rainy weather.

[0015] As a further improvement of the present invention, the mobile inspection terminal is equipped with an AR augmented reality interface, which can overlay and display the photosynthetic efficiency parameters of the rubber tree and the working status of the fill light module in real time, and supports gesture operation to adjust the spectral ratio.

[0016] The beneficial effects of the present invention are as follows: the present invention significantly improves the accuracy and adaptability of the rubber forest supplementary lighting system by integrating multi-dimensional environmental perception, phenological period self-identification spectral control and cloud-edge collaborative decision-making mechanism: the system can dynamically optimize the spectral composition according to the physiological characteristics of rubber trees in different growth stages, especially enhance the far-red light band during the tapping period to promote latex synthesis; the modular supplementary lighting array combined with light intensity threshold control realizes efficient energy utilization and effectively copes with light stress in rainy weather; the local caching strategy ensures continuous and reliable operation during communication interruption and reduces management risks; at the same time, with the help of AR augmented reality interactive interface, the efficiency of field inspection and regulation is greatly improved, which fundamentally solves the problems of rigid spectral adaptation, delayed environmental response and extensive management of traditional supplementary lighting systems, and provides an intelligent and refined lighting management solution for the rubber planting industry. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the embodiments described herein are only used to explain this application and are not intended to limit this application.

[0019] The present invention provides a rubber forest intelligent spectrum control and supplementary lighting system, which includes an environmental perception module, a spectrum adjustable supplementary lighting module, a central control module, a power supply and communication module, a cloud data platform, and a mobile inspection terminal.

[0020] The environmental perception module is used to collect rubber forest growth environment parameters in real time; the spectrally adjustable fill light module contains multiple groups of independently controllable LED light source units, each unit can emit spectra of different wavelengths; the central control module connects the environmental perception module and the spectrally adjustable fill light module, and generates a fill light strategy based on environmental parameters and a preset rubber tree spectral demand model; the power supply and communication module supplies power to the system and supports remote data transmission; the cloud data platform receives data uploaded by the central control module, and optimizes the spectral demand model through machine learning before sending it to each terminal; the mobile inspection terminal receives system alarm information through wireless communication and supports manual override of the fill light strategy.

[0021] The environmental perception module in the present invention includes a light intensity sensor, a multispectral sensor, a temperature and humidity sensor, and a soil moisture sensor. Among them, the multispectral sensor includes a dual-channel detector of visible light (400-700nm) and near-infrared (700-1000nm), which monitors the chlorophyll reflectance characteristics of rubber trees in real time with a spectral resolution of 0.5-2nm.

[0022] The LED light source units in the spectrally adjustable fill light module of this invention include four wavelength bands: red (630–660nm), blue (450–470nm), far-infrared (730–750nm), and ultraviolet (380–400nm). The brightness of each wavelength band is independently adjustable. The spectrally adjustable fill light module adopts a modular array layout, with a single fill light unit covering an area of ​​≤4 square meters. The spacing between units is adaptively adjusted according to the crown diameter of the rubber tree.

[0023] In the present invention, the central control module has a built-in rubber tree phenological period recognition algorithm, which identifies rubber trees in the seedling stage, growth stage, and tapping stage according to environmental data, and matches the corresponding spectral formula. For rubber trees in the tapping stage, the far-red light band ratio in the spectral formula is increased to 30%-40%, and the blue light band ratio is reduced to 10%-15%, and the daily light filling period is limited to 2 hours before and 4 hours after the tapping operation. The central control module configures a local strategy cache unit, which automatically switches to the verified light filling strategy executed in the last 72 hours when communication is interrupted, and records an abnormal status log. The central control module integrates an energy-saving control strategy, which automatically turns off the light filling module when the ambient light intensity is ≥8000lux, and starts the red light band enhancement mode (red light intensity is increased to 120%-150% of the normal value) in continuous rainy weather.

[0024] The mobile inspection terminal in the present invention is equipped with an AR augmented reality interface, which can overlay and display the photosynthetic efficiency parameters of the rubber tree and the working status of the fill light module in real time, and supports gesture operation to adjust the spectral ratio.

[0025] Example:

[0026] In the rubber tapping season of a rubber plantation in Yunnan (21.9 ° north latitude, 101.2 ° east longitude), the intelligent spectrum control light supplementation system of the present invention was deployed. The rainy season in this region is frequent, and the average daily effective illumination is less than 5 hours. During system installation, according to the characteristics of 3.8 meters of rubber tree average crown diameter, the spectrum adjustable light supplementation module is pressed into the diamond array layout, and each light supplementation unit covers 3.5 square meters of area, and the unit spacing is automatically adjusted to 3.2 meters.

[0027] 1. Environmental Perception and Decision-Making

[0028] At 05:30 in the morning, the environmental perception module detected that the light intensity was only 1800 lux (the second day of continuous rain), the soil moisture content reached 42%, and the multispectral sensor detected an abnormal decrease in chlorophyll reflectance. The central control module confirmed that the rubber trees were in the tapping period through the phenological period recognition algorithm and immediately implemented the following strategies: (1) Start the red light enhancement mode (red light intensity increased to 130% of the normal value); (2) Use a special spectral formula for the tapping period: far red light accounts for 38%, blue light accounts for 12%, red light accounts for 45%, and ultraviolet light accounts for 5%; (3) The supplementary light period is set to 2 hours before the tapping operation (06:00-08:00).

[0029] (2) Exception handling and manual intervention

[0030] At 7:15 AM, the mobile inspection terminal received an alarm about a "spectral deviation in zone 3 fill light unit." A technician wearing AR glasses inspected the area, and the following real-time overlays appeared in their field of view: (1) the photosynthetic efficiency of the target rubber tree was 0.72 (normal range 0.85-1.1); (2) the blue light output of the faulty fill light unit was only 65% ​​of the set value. Using a swipe gesture, the blue light output was temporarily increased to 15%, and the location was marked for inspection.

[0031] (3) Response to Communication Interruptions

[0032] At 2:20 p.m., a sudden strong thunderstorm caused communication interruption, and the system automatically activated the local strategy cache unit: (1) retrieved the effective supplementary lighting strategy under the same meteorological conditions (humidity>90%, temperature 26-28°C) in the past 72 hours; (2) maintained a conservative ratio of 35% far-infrared light and 50% red light; (3) continuously recorded environmental parameters and device status logs.

[0033] (4) Cloud Optimization and Strategy Update

[0034] The next day, after communications were restored, the cloud data platform optimized the spectral demand model based on uploaded abnormality logs and latex production data: (1) the red light enhancement threshold for rainy days was increased from 120% to 135%; and (2) the red light-UV light ratio was increased four hours after tapping. The new strategy was immediately sent to the central control module for execution.

[0035] Implementation Effect

[0036] Compared with traditional fixed-spectrum supplementary lighting systems, this system maintains stable latex production under continuous rainy conditions; the modular layout reduces the ineffective irradiation area by 35%, and combined with the automatic shutdown function when the light intensity is ≥8000lux, the overall energy consumption is reduced by 45%; the AR interactive interface increases fault handling efficiency by 3 times, and the average response time is shortened to within 8 minutes; the local caching strategy during communication interruptions ensures uninterrupted operation for 72 consecutive hours.

[0037] It can be seen from this embodiment that the system achieves accurate spectral regulation, efficient energy utilization and intelligent operation and maintenance management in a changeable field environment, effectively solving the core problem of lighting management in rubber forests.

[0038] In summary, a kind of rubber forest intelligent spectrum control light-filling system of the present invention not only shows excellent performance in this embodiment, but also has broad application prospects in future rubber forest planting by fusing multidimensional environmental perception, phenological period self-identification spectrum control and cloud edge collaborative decision-making mechanism. With the continuous development of technology, cloud data platform can collect more rubber forest growth data in different regions and different climatic conditions, and further optimize spectrum demand model. For example, for rubber forests at different altitudes, there are differences in environmental factors such as its illumination, temperature, humidity, and the cloud can customize exclusive light-filling strategies for rubber forests in different regions according to these data.

[0039] Furthermore, with the continuous advancement of machine learning algorithms, cloud-based data platforms can more accurately analyze the relationship between rubber tree growth and lighting strategies. For example, through deep learning of large amounts of data, they can predict potential problems that may arise in rubber trees at different growth stages and adjust lighting strategies in advance, thereby further improving latex yield and quality.

[0040] In terms of system scalability, more functional modules can be added to the existing modules in the future. For example, a pest and disease monitoring module could be added to detect signs of pests and diseases through image recognition and spectral analysis of rubber trees, and then combined with supplemental lighting strategies to prevent and control them. A fertilizer management module could also be added to provide reasonable fertilization recommendations based on the rubber tree's growth environment and phenological period.

[0041] Furthermore, to better suit the needs of different users, the system offers more personalized settings. Users can fine-tune the supplemental lighting strategy based on their own planting experience and actual needs, making the system more tailored to their actual production conditions.

[0042] With the continuous advancement of science and technology and the deepening of its application, the rubber forest intelligent spectrum control and lighting supplement system of the present invention will continue to be improved and developed, providing stronger support for the sustainable development of the rubber planting industry.
