[0029] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0030] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0032] like Figures 1 to 5As shown, a plant growth lighting control method according to a first aspect embodiment of the present invention is applied to a maintenance system. The maintenance system includes a petri dish 510, a light sensor 520, a camera assembly 530, a light source assembly 540, and a control module 550. The petri dish 510 is used for planting plants. The light source assembly 540 is located above the petri dish 510. The light sensor 520 is used to detect light information. The camera assembly 530 is used to capture plant images. The control module 550 is connected to the light sensor 520, the camera assembly 530, and the light source assembly 540 respectively. The control module 550 executes the plant growth lighting control method, which includes:

[0033] S110. Acquire plant images and perform feature comparison on the plant images to obtain plant attributes, wherein the plant attributes include at least plant species and growth status.

[0034] S120. Match the corresponding regulation strategy data in the database according to the plant attributes, wherein the regulation strategy data includes one or more of the target brightness value, the target wavelength value, and the target duration value.

[0035] S130. Obtain illumination information and adjust the light emission of the light source component according to the illumination information and control strategy data.

[0036] The petri dish can be a regular planting pot, vase, etc., and the camera component can be selected from regular camera instruments. The camera component can be placed on one side of the petri dish and facing the plant planted on the petri dish.

[0037] Specifically, different types of plants have their own unique feature outlines. By acquiring the feature outlines and some feature points in plant images, they can be classified into plant species with high similarity, and the growth status of plants can be determined based on information such as plant height and width.

[0038] The light sensor is placed on or near the petri dish. It is understood that the light sensor is used to detect the light information of the plant's environment.

[0039] The light source assembly may include at least a first LED group and a second LED group with different wavelengths. Both the first and second LED groups may be composed of LED beads connected in series, in parallel, or in a mixed configuration. The control module may form a first driving branch by connecting a first switching transistor in series with the first LED group, and a second driving branch by connecting a second switching transistor in series with the second LED group. The power supply may be connected to the first and second driving branches respectively. The control module may be connected to the first and second switching transistors respectively. The first and second switching transistors may be transistors or MOSFETs, etc. By controlling the switching frequency of the first and second switching transistors, the current ratio through the first and second LED groups can be adjusted, thereby adjusting the wavelength of the combined light. It can be understood that the wavelength of the combined light varies between the emission wavelength of the first and second LED groups. In addition, by controlling the magnitude of the operating current, the brightness of the light can be controlled.

[0040] This invention relates to a plant growth lighting control method. By extracting features from plant images and analyzing feature points, the method determines the plant type and growth status. Then, based on these plant attributes, it matches corresponding control strategy data from a database. Since indoor environments may also have sunlight or radiation from other light sources, the light sensor detects ambient light information. Based on this information and the control strategy data, the light source component is adjusted to emit light, ensuring that the light intensity of the plant's environment after supplemental lighting approaches the level required by the control strategy data. This intelligent control provides a suitable lighting environment for plant growth, promoting optimal plant development.

[0041] In some embodiments of the present invention, the light sensing device includes a light wavelength sensor, the light wavelength sensor is used to detect the actual value of the light wavelength, the control strategy data includes a target wavelength value, and the plant growth lighting control method includes:

[0042] Obtain the actual value of the illumination wavelength;

[0043] Adjust the emission wavelength of the light source component so that the actual value of the illumination wavelength approaches the target wavelength value.

[0044] It is understandable that shorter wavelengths of light, with a blue tint, are beneficial for plant growth. Therefore, the control strategy data includes the light wavelengths suitable for the growth of different plant species.

[0045] The light wavelength sensor measures the actual light wavelength in the environment. The control module controls the emission wavelength of the light source component. The light emitted by the light source component mixes with the light present in the environment and shines on the plant. The control module provides feedback control based on the actual light wavelength value, thereby making the actual light wavelength value approach the target wavelength value.

[0046] It is understood that different types of plants have their relatively fixed growth patterns. For example, different plants can tolerate different durations of lower wavelength light, or different plants can tolerate different numbers of lower wavelength light exposures per day. In some embodiments of the present invention, the target wavelength value includes at least a first target value and a second target value, wherein the wavelength of the first target value is less than the second target value, and the target duration value includes the total target wavelength duration; such as Figure 2 As shown, the plant growth lighting regulation method includes:

[0047] S210, Record actual clock information;

[0048] S220: Control the light source component to emit light according to the actual value of the illumination wavelength approaching the first target value and record the first time period;

[0049] S230: When the total duration of the wavelength target is reached in the first time period, the light source component is controlled to emit light according to the actual value of the illumination wavelength approaching the second target value.

[0050] S240. When the actual clock information reaches the switching time node, the first time period will be cleared.

[0051] Understandably, light reaching the first target value has a shorter wavelength, which can promote plant growth but cannot be used for prolonged exposure. Light reaching the second target value, however, is closer to ordinary indoor ambient light and can provide long-term illumination for plants. The total duration of the target wavelength is set by the manufacturer or user according to the needs of different plant species. The switching time can be set at midnight, 12:00, or 24:00, or can be set by the manufacturer or user. When the actual clock information reaches the switching time, the first time period is reset to zero. After the first time period is reset, the light source component can be controlled again to emit light according to the first target value, thus compactly meeting the plant's light wavelength requirements, improving plant growth efficiency, and promoting flowering and fruiting.

[0052] In some embodiments of the present invention, the control strategy data includes a time-brightness curve, and the light sensing device includes a brightness sensor, which is used to detect the actual value of the brightness, such as... Figure 3 As shown, the plant growth lighting regulation method includes:

[0053] S310, Record actual clock information;

[0054] S320. Obtain the target brightness value from the time and brightness curve based on the actual clock information;

[0055] S330, Obtain the actual value of light intensity;

[0056] S340. Adjust the brightness of the light source component so that the actual brightness value approaches the target brightness value.

[0057] The time-brightness curve represents the light intensity required by the plant as the real-time clock changes. Therefore, the target brightness value can be obtained from the time-brightness curve based on the real-time clock information. It is understandable that as the real-time clock information changes, the control module needs to continuously adjust the target brightness value based on the time-brightness curve, and then use the actual brightness value to control the light source component to emit light so that the actual brightness value approaches the target brightness value.

[0058] Similarly, different types of plants have their own growth rhythms, and most plants cannot continuously receive light for 24 hours. In some embodiments of the present invention, the target duration value includes the total target duration of light exposure; such as... Figure 4 As shown, the plant growth lighting control method further includes:

[0059] S410, Record the second time period during which the light source component lights up;

[0060] S420: When the cumulative duration of the second time period reaches the target illumination time, the light source component is turned off.

[0061] S430: When the actual clock information reaches the replacement time node, the second time period will be cleared.

[0062] The total duration of the target light exposure is set by the manufacturer or user according to the needs of different types of plants. The replacement time can be set at 24:00, 12:00, or 24:00, etc., which can also be set by the manufacturer or user.

[0063] It is understandable that when calculating the total duration of illumination on the target, the light source component emits light according to the target brightness value from the moment it is turned on, and a second time period is recorded. When the second time period reaches the total duration of illumination on the target, the light source component can be turned off. However, when the actual clock information reaches the replacement time node, the second time period will be reset to zero, and the light source component will be turned on again.

[0064] In some embodiments of the present invention, the plant growth lighting regulation method includes:

[0065] Upon receiving an information retrieval request, the camera module is activated to capture images of the plants.

[0066] Upload plant images, plant attributes, and light information to the server;

[0067] The server provides plant images, plant attributes, and light information to the smart device that sends the information retrieval request.

[0068] Users can send information retrieval requests to the server via smart devices such as mobile phones and tablets. Each petri dish and its corresponding control module, camera component, etc., has its own identification code. The information retrieval request uses the identification code information to obtain the corresponding plant image, as well as plant attributes and light information, to determine the type of plant and the current ambient light.

The server 560 provides plant images, plant attributes and light information to the smart device according to the information retrieval request.
