Description

Technical Field

[0001] This invention belongs to the technical field of plant supplemental lighting systems, and in particular relates to an intelligent plant supplemental lighting system that can perform multi-parameter control based on address and instructions to match plant growth targets. Background Technology

[0002] In the current field of facility agriculture and plant factories, artificial lighting has become a core technology for ensuring crop yield and quality. Traditional lighting systems generally adopt a centralized group control mode: the controller uses analog or simple switching signals to uniformly turn on and off or adjust the brightness of multiple supplementary lights in the same circuit, which cannot achieve fine control at the single-lamp level.

[0003] These traditional systems suffer from the following core technological shortcomings: Homogeneous lighting strategies cannot match the differentiated needs of crops: all lamps in the same power supply circuit can only output the same light intensity and light quality, making it impossible to customize exclusive lighting formulas for crops at different growth stages, different varieties, or different planting areas. This results in some crops receiving excessive or insufficient light, limiting the efficiency of light energy utilization and the growth potential of crops.

[0004] Insufficient communication and control precision makes it difficult to achieve intelligent regulation: Traditional supplementary lighting systems mostly use non-addressable communication methods, making it difficult for the controller to accurately identify and control individual lamps, implement complex time-sequential lighting strategies (such as time-segmented light intensity changes and light quality ratio switching), and also unable to monitor the lamp operating status in real time and locate faults, resulting in a low level of system intelligence.

[0005] Poor system scalability and compatibility: The control loop of traditional supplemental lighting systems is tied to the number of lamps. When adding or adjusting lamps, rewiring and configuration are required. It cannot flexibly adapt to planting scenarios of different scales, and it is difficult to achieve linkage control with environmental control equipment (such as water pumps and ventilation equipment), which limits the level of automation of overall planting management.

[0006] With the development of plant factories and precision agriculture, the market urgently needs an intelligent supplemental lighting system that can achieve single-lamp addressability, differentiated light formula output, and multi-device linkage to solve the technical problems of traditional supplemental lighting systems, such as single lighting strategy, insufficient control precision, and poor scalability, thereby improving the production efficiency and crop quality of facility agriculture.

[0007] To address these issues, we provide an intelligent plant supplemental lighting system that can perform multi-parameter control based on address and instructions to match plant growth targets. Summary of the Invention

[0008] The purpose of this invention is to provide an intelligent plant supplemental lighting system that can perform multi-parameter regulation based on address and instructions to match plant growth targets. Through the cooperation of a power supply module, an intelligent lighting module, and an intelligent control module, it solves the problems of homogenized lighting strategies in existing supplemental lighting systems, inability to match the differentiated needs of crops, insufficient communication and control precision, difficulty in achieving intelligent regulation, and poor system scalability and compatibility.

[0009] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution.

[0010] This invention relates to an intelligent plant supplemental lighting system capable of multi-parameter control based on address and instructions matched to plant growth goals. The system includes a power supply module, an intelligent lighting module, and an intelligent control module. The power supply module provides power to the intelligent lighting module and the intelligent control module. The intelligent control module and the intelligent lighting module establish a communication connection via a digital bus. Each intelligent lighting unit in the intelligent lighting module has a unique address. The intelligent control module can independently control the light quality and light intensity parameters of a specified intelligent lighting unit based on the address. Furthermore, it can edit and output time-varying light quality and light intensity control instructions according to plant growth goals, thereby achieving programmed control of the intelligent lighting units.

[0011] The present invention is further configured such that the power supply module is a high-power switching power supply, which converts three-phase or single-phase mains power into a DC safe voltage isolated from the mains power, and the capacity of the high-power switching power supply is 1.2-1.5 times the total power of all lamps in the intelligent lighting module.

[0012] The present invention is further configured such that the DC safety voltage of the power supply module is 48Vdc; the digital bus adopts the MODBUS bus communication protocol and has A, B, and G communication channels to realize stable data transmission between the intelligent control module and the intelligent lighting module.

[0013] The present invention is further configured such that the intelligent control module includes a human-computer interaction unit, a data storage unit, a parameter parsing unit, and a bus communication unit; the human-computer interaction unit is used to input light quality, light intensity, and time-related parameters required for plant growth; the data storage unit is used to save the input control parameters; the parameter parsing unit is used to parse the control parameters and generate corresponding control commands; and the bus communication unit is used to send the control commands to the digital bus.

[0014] The present invention is further configured such that the control parameters stored in the data storage unit can be automatically read by the intelligent control module after the system is powered on, without the need for resetting, until the control parameters are manually modified.

[0015] The present invention is further configured such that the bus communication unit cyclically sends the generated control commands to the digital bus, and the designated smart lamp in the smart lamp module performs the corresponding light-emitting operation according to the received current control command.

[0016] The present invention is further configured such that the intelligent lamp has at least one light-emitting channel, each light-emitting channel corresponds to a dedicated register address on a digital bus, and the intelligent control module achieves precise control of the light intensity of the corresponding light-emitting channel by writing working parameters to the specified register address.

[0017] The present invention is further configured such that the operating parameters characterize the operating status and power ratio of the light-emitting channel in the form of digital codes, and the adjustment accuracy of the power ratio is 1 / 255, which can realize the continuous adjustment of the light-emitting channel from shutdown to full power operation.

[0018] The present invention is further configured such that when the intelligent lamp is provided with multiple light-emitting channels, each light-emitting channel is independently controlled and combined to form different light qualities, and the number of combinations of light qualities is 2 to the power of 8N, where N is the number of light-emitting channels.

[0019] The present invention is further configured such that the intelligent control module can perform partitioned or single-lamp-level independent addressing control of the intelligent lamps on the digital bus, and the intelligent lamps with different address addresses can be configured with different light quality and light intensity output strategies, and the system can accurately and repeatedly output the configured light quality and light intensity parameters.

[0020] The present invention has the following beneficial effects.

[0021] 1. This invention fundamentally solves the problem of homogenized lighting strategies caused by the unified control of groups in traditional supplemental lighting systems by assigning a unique address to each smart lamp and using a digital bus to achieve independent communication control at the lamp level. Compared with traditional systems where lamps in the same circuit can only output homogenized lighting, this invention can customize and output differentiated light formulas for crops at different growth stages, different varieties, or different planting areas, effectively avoiding the problem of excessive or insufficient light and significantly improving light energy utilization efficiency and crop growth potential.

[0022] 2. This invention solves the defects of traditional supplemental lighting systems, such as low control accuracy, insufficient intelligence, and poor scalability, by using digital bus communication and register-level precise control. Compared with the limitations of traditional systems, such as non-addressable communication, inability to monitor the status of individual lamps, and fixed wiring, this invention achieves precise execution of complex time-sequential lighting strategies and real-time perception of lamp status. Moreover, the system can flexibly adapt to different scale planting scenarios, greatly improving the intelligence level and scenario adaptability of the supplemental lighting system.

[0027] The technical solutions of the present invention will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Example 1 Please see Figures 1-3This invention discloses an intelligent plant supplemental lighting system capable of multi-parameter control based on address and command matching to plant growth targets. It includes a power supply module, an intelligent lighting module, and an intelligent control module. The power supply module provides power to the intelligent lighting module and the intelligent control module. The intelligent control module and the intelligent lighting module establish a communication connection via a digital bus. Each intelligent lighting unit in the intelligent lighting module has a unique address. The intelligent control module can independently adjust the light quality and light intensity parameters of a specified intelligent lighting unit based on the address. Furthermore, it can edit and output time-varying light quality and light intensity control commands according to plant growth targets, thus realizing the programmable control of the intelligent lighting units. The intelligent lighting module features a high-power switching power supply that converts three-phase or single-phase mains power into a safe DC voltage isolated from the mains. The capacity of this high-power switching power supply is 1.2-1.5 times the total power of all lights in the intelligent lighting module, and the DC safe voltage of the power supply module is 48Vdc. The digital bus uses the MODBUS bus communication protocol and has A, B, and G communication channels to achieve stable data transmission between the intelligent control module and the intelligent lighting module. The intelligent control module includes a human-machine interaction unit, a data storage unit, a parameter parsing unit, and a bus communication unit. The human-machine interaction unit is used to input the parameters required for plant growth. The system includes light quality, light intensity, and time-related parameters. A data storage unit stores the input control parameters, a parameter parsing unit parses the parameters and generates corresponding control commands, and a bus communication unit sends these commands to the digital bus. The control parameters stored in the data storage unit can be automatically read by the intelligent control module after system power-on, without needing to be reset until manually modified. The intelligent lighting fixture has at least one light-emitting channel, each corresponding to a dedicated register address on the digital bus. The intelligent control module achieves precise control of the light intensity of the corresponding light-emitting channel by writing operating parameters to the specified register address. The operating status and power ratio of the light-emitting channels are represented by digital codes. The power ratio adjustment accuracy is 1 / 255, which can realize continuous adjustment of the light-emitting channels from power off to full power operation. When the smart lamp has multiple light-emitting channels, each light-emitting channel can be independently controlled and combined to form different light qualities. There are 2 to the power of 8N combinations of light qualities, where N is the number of light-emitting channels. The intelligent control module can perform zoned or single-lamp-level independent addressing control of the smart lamps on the digital bus. Smart lamps with different address addresses can be configured with different light quality and light intensity output strategies, and the system can accurately and repeatedly output the configured light quality and light intensity parameters.

[0029] Example 2: Supplemental lighting for leafy vegetables in a greenhouse This invention's intelligent supplemental lighting system is used when cultivating leafy vegetables such as lettuce and spinach in large-scale multi-span greenhouses. The greenhouse is divided into seedling, growth, and harvesting zones according to crop growth stages, with each zone's LED supplemental lights assigned independent addressing addresses. The intelligent control module configures a low-intensity, high-blue-light formula for the seedling zone based on the light requirements of different growth stages, promoting robust seedling growth; a medium-intensity, balanced red-blue light formula for the growth zone, accelerating leaf growth; and a high-intensity, high-red-light formula for the harvesting zone, improving leaf quality and yield. The system distributes the zoned strategy to each light fixture via the MODBUS bus, enabling differentiated lighting control across different areas of the same greenhouse. Compared to traditional uniform supplemental lighting, leafy vegetable yields are increased by over 15%, and uniformity is improved to 95%.

[0030] Example 3: Precision cultivation scenario of medicinal plants in a plant factory This invention's system is used when cultivating medicinal plants such as Dendrobium officinale and Anoectochilus roxburghii in indoor plant factories. Because medicinal plants are sensitive to light quality ratios (such as the ratio of ultraviolet to red light), each supplemental light lamp is configured with multiple light-emitting channels (red, blue, and ultraviolet light channels), each corresponding to an independent register address. The intelligent control module creates a time-sequential light formula based on the accumulation requirements of secondary metabolites in the medicinal plants: a high red light and medium blue light ratio is configured during the day to promote photosynthesis, while at night, a low light intensity and a specific ultraviolet light ratio are used to stimulate the synthesis of medicinal components. The system precisely controls the channel output of each lamp through single-lamp addressing, ensuring a 20% increase in the content of effective components in medicinal plants, thus solving the problem that traditional supplemental lighting cannot accurately control light quality and cannot meet the special growth needs of medicinal plants.

[0031] Example 4: Scenario of coordinated control in a large-scale seedling factory In an intensive seedling nursery, this invention's supplemental lighting system is linked with irrigation pumps and environmental sensors. The intelligent control module not only controls the supplemental lights above each seedling tray via the MODBUS bus but also synchronously controls the corresponding water pump actuators. When the sensor detects insufficient moisture in the seedling substrate in a certain area, the intelligent control module first issues a command to reduce the light intensity of the supplemental lights in that area to prevent high temperatures from exacerbating moisture evaporation, and then triggers the water pump to start precise irrigation; after irrigation, the original light formula strategy is restored. Compared to the traditional mode of independent control of supplemental lighting and irrigation, this system achieves coordinated regulation of light and water and fertilizer, preventing seedlings from wilting due to high temperature and water shortage, increasing the seedling survival rate to over 98%, while reducing energy and water consumption.

[0032] Example 5: Miniaturized Supplemental Lighting Scenarios for Home Gardening This miniaturized version of the invention is suitable for growing strawberries, herbs, and other gardening crops on home balconies or tabletops. The system is equipped with a small number of LED grow lights, each retaining an independent address. Users input crop growth goals (such as "strawberry fruiting stage") via a mobile app (a simplified smart control module), and the system automatically generates the corresponding light formula, which is then transmitted to the lights via Bluetooth-to-MODBUS bus. Users can adjust the light intensity and quality of individual lights at any time in the app, and even configure different strategies for different potted plants. Compared to traditional household grow lights that can only be switched on / off or have overall dimming, this invention achieves precise supplemental lighting in home gardening scenarios, allowing amateur growers to obtain a lighting environment close to that of professional gardeners, improving the success rate and enjoyment of home gardening.
