Description

Technical Field

[0001] This invention relates to the field of laser agricultural lighting equipment, specifically to a laser plant control device, control method, and medium. Background Technology

[0002] Plant grow lights utilize semiconductor lighting principles to assist the growth of crops such as grains, flowers, and vegetables. Generally, greenhouse crops and indoor plants tend to decline in growth over time, primarily due to insufficient light. Illuminating them with light sources that provide the necessary spectrum can promote growth, increase yield, and improve crop quality. Applying plant grow lights to greenhouses and other agricultural facilities can address the problem of insufficient sunlight leading to decreased yield and quality. Furthermore, it allows greenhouse fruits and vegetables to be harvested earlier in winter, achieving the goal of off-season cultivation.

[0003] While existing plant grow lights have light intensity regulation functions, they mainly rely on manual adjustment and cannot adapt to changes in the environment. Environmental temperature, humidity, and light intensity all affect the amount of light absorbed by plants during their growth. Furthermore, there are two key points in plant photosynthesis: the light compensation point and the light saturation point. Once the light compensation point is reached, the photosynthetic rate increases with increasing light intensity. However, once a certain light intensity is reached, the photosynthetic rate no longer increases with increasing light intensity, which is the light saturation phenomenon. At this point, if the external light intensity is greater than the plant's light saturation point, the plant will not absorb more light, resulting in a waste of light.

[0004] Existing research indicates that different laser wavelengths require varying light intensities for laser regulation at different plant growth stages. Therefore, it is necessary to adjust the laser intensity of different wavelengths according to ambient light and the plant's growth stage. While the regulatory effect of lasers on plant physiological cycles is very evident experimentally, to prevent light waste, feedback adjustment of the laser intensity is required, supplementing the light intensity in accordance with the plant's growth stage.

[0022] In the following description, embodiments of the invention will be described with reference to the accompanying drawings. In the description below, the same modules are denoted by the same reference numerals. Where the same reference numerals are used, their names and functions are also the same. Therefore, their detailed description will not be repeated.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not constitute a limitation thereof.

[0024] Please see Figure 1 and Figure 2 In a first aspect, this embodiment provides a laser plant control device 14, including a base 12, a light-diffusing element 1, a control unit 6, a light source, a driving circuit, a communication unit 7, and a sensing component. The base 12 includes a receiving cavity and a light-transmitting port, the light-transmitting port being connected to the receiving cavity; the light-diffusing element 1 is disposed in the light-transmitting port; the light source is disposed in the receiving cavity, with its output end facing the light-diffusing element 1, and the light source is used to output lasers of multiple different wavelengths, preferably including a first-wavelength laser and a second-wavelength laser; the driving circuit is disposed in the receiving cavity and electrically connected to the light source and the control unit 6, respectively, and is used to adjust the relevant parameters of the light source according to the control commands of the control unit 6; the communication unit 7 is disposed in the receiving cavity and electrically connected to the control unit 6, and is used to establish a communication connection with a server to obtain plant-related information; the sensing component is disposed in the receiving cavity and is used to collect environmental parameter information, and is electrically connected to the control unit 6; the control commands of the control unit 6 include the operating parameters of the light source, which are generated based on plant-related information and / or environmental parameter information.

[0025] In this embodiment, the base 12 can be understood as a supporting component for fixing other parts. Specifically, the base 12 can be a shell, frame, or rack. The base 12 includes a receiving cavity, and the control unit 6, light source, drive circuit, and communication unit 7 can all be disposed within the receiving cavity. A light-transmitting port is also provided on the base 12, which communicates with the receiving cavity. A light-diffusing element 1 is disposed at the light-transmitting port. Specifically, the light-diffusing element 1 can be a combination of multiple optical lenses or a single unit. This embodiment does not limit the light-diffusing element 1. The light-diffusing element 1 is used to uniformly disperse the first-band laser and the second-band laser output from the light source into the planting area, where plants 15 are planted.

[0026] The light source is a laser, specifically a dual-frequency laser or a single-frequency laser. The driving circuit is electrically connected to the light source and is a semiconductor laser pulse driving circuit. The driving circuit can drive the light source to generate repetitive pulse laser with a certain amplitude, frequency and pulse width. The repetitive pulse laser can improve the photosynthetic rate of plants and reduce the energy loss of the light source.

[0027] In this embodiment, the first and second wavelength lasers correspond to the light waves required for photosynthesis in plant 15. For example, the first wavelength can be understood as the wavelength range containing red light, and the second wavelength can be understood as the wavelength range containing blue light. Specifically, the specific wavelength ranges of the first and second wavelengths can be further set according to the species of plant 15 to meet the photosynthetic needs of different species of plant 15.

[0028] The communication unit 7 varies depending on the communication connection method used in the actual application. For example, the communication unit 7 can be an NB-IoT Internet of Things communication device, or a Bluetooth communication device, a StarFlash communication device, a WIFI communication device, or a 4G network standard communication device, etc. Optionally, the communication unit 7 can also establish a connection with a preset terminal 13 for communication with the preset terminal 13. The preset terminal 13 can be a mobile phone, tablet, laptop, etc., or an infrared remote control, depending on the actual needs.

[0029] The communication unit 7 is used to collect plant-related information, which refers to the information of the plant 15 planted in the current planting area. Specifically, it includes the plant species, the current growth stage of the plant 15, and the light intensity required by the plant 15 at this growth stage. Specifically, the light intensity refers to the wavelength range and intensity of the light wave corresponding to the highest photosynthetic efficiency of this plant 15.

[0030] The sensing component is used to collect environmental parameter information, including ambient temperature and humidity, and the intensity of light already present in the environment.

[0031] The control commands of the control unit 6 include the operating parameters of the light source. This can be understood as follows: the light source and the drive circuit work together to generate the first and second band lasers; therefore, the operating parameters of the light source correspond to the adjustment of the light source and the drive circuit. The operating parameters are generated based on plant-related information and / or environmental parameters. Specifically, the control unit 6 can obtain the operating parameters of the light source based on the existing light intensity in the environment and the light intensity corresponding to the highest photosynthetic efficiency during the current growth stage of the plant 15. Specifically, by calculating the difference between the light intensity required by the plant 15 and the existing light intensity in the environment, the required light intensities of the first and second band lasers can be obtained, and then the operating parameters of the light source can be calculated.

[0032] Please see Figure 1 In some embodiments, the light source includes a first light source 2 and a second light source 3 arranged in parallel. The first light source 2 is used to output a first band laser, and the second light source 3 is used to output a second band laser. The driving circuit includes a first driving circuit 4 and a second driving circuit 5. The first driving circuit 4 is electrically connected to the first light source 2, and the second driving circuit 5 is electrically connected to the second light source 3.

[0033] In this embodiment, the light source includes a first light source 2 and a second light source 3 arranged side by side. Here, "side by side" means arranged opposite each other to the light-passing port, facilitating simultaneous light homogenization of the first light source 2 and the second light source 3 by the light homogenizer 1. The first light source 2 generates laser light of a first wavelength, denoted as the first-wavelength laser, and the second light source 3 generates laser light of a second wavelength, denoted as the second-wavelength laser. Correspondingly, the driving circuit includes a first driving circuit 4 and a second driving circuit 5. The first driving circuit 4 is connected to the first light source 2, and the second driving circuit 5 is connected to the second light source 3. The control unit 6 controls the first driving circuit 4 and the second driving circuit 5 respectively to adjust the first-wavelength laser and the second-wavelength laser.

[0034] In some embodiments, the sensing components include any one of a temperature sensor, a humidity sensor, a vision sensor, a spectral sensor, and a timer. In this embodiment, the temperature sensor is used to collect ambient temperature information of the current planting area; the humidity sensor is used to collect ambient humidity information of the current planting area; the vision sensor is used to collect image information of the current planting area, and extract image data of the plant 15 in the current planting area based on the image information, and determine the current growth stage of the plant 15 based on the image data of the plant 15; the spectral sensor is used to collect ambient light information of the current planting area, the ambient light information including the light intensity of a first band and the light intensity of a second band in the environment.

[0035] It should be noted that the timer is used to synchronize the current time data. The photosynthetic rate of plant 15 is different during the day and at night, and the light intensity in the environment is also different. Therefore, the addition of the timer makes it easier for control unit 6 to adjust the first band laser and the second band laser according to the time data of the timer.

[0036] In a preferred embodiment, the device may further include a power supply unit 11 and a DC voltage regulator module 10. The laser plant control device of the present invention can be powered by either AC or DC power. When connected to a DC power source, the power supply unit 11 can be a lithium battery, lead-acid battery, solar panel, etc. When powered by AC power, the DC voltage regulator module 10 can be used to convert AC power into DC power for the control unit 6, drive circuit, and light source. Figure 2 The diagram shows one form of the power supply unit 11 as a solar panel. It should be noted that when the power supply unit 11 is a solar panel, the power supply unit 11 should be set outside the base 12 and facing south. Preferably, the angle between the surface of the solar panel and the horizontal plane should correspond to the local latitude.

[0037] As another preferred embodiment, it may also include a first display unit 8 and a second display unit 9. The first display unit 8 and the second display unit 9 are disposed outside the base 12. Both the first display unit 8 and the second display unit 9 are electrically connected to the control unit 6. The first display unit 8 is used to display the information of the current first band laser, including the band range, band amplitude, band frequency, band pulse, etc. of the first band laser. The second display unit 9 is used to display the information of the current second band laser, including the band range, band amplitude, band frequency, band pulse, etc. of the second band laser. This method makes it convenient for users to directly check the supplementary lighting status of the supplementary lighting device.

[0038] Please see Figure 3 In a second aspect, this embodiment also provides a laser plant regulation method, applicable to the laser plant regulation device described in the first aspect, the method comprising:

[0039] S11. Obtain environmental parameter information and plant-related information. The environmental parameter information includes at least one of temperature information, humidity information, light information and time information. The plant-related information includes the growth type, growth habits and growth status of the currently planted plants.

[0040] S12. Generate first reference light intensity information based on environmental parameter information, and generate second reference light intensity information based on plant-related information and environmental parameter information;

[0041] S13. Generate the operating parameters of the light source based on the first reference light intensity information and the second reference light intensity information;

[0042] S14. The control drive circuit adjusts the relevant parameters of multiple light sources of different wavelengths according to the operating parameters.

[0043] In this embodiment, the environmental parameter information refers to the temperature, humidity, light, and time information of the environment in which the current planting area is located. Specifically, the light information includes the light intensity of the first band and the light intensity of the second band in the environment, and the time information is the current time data, such as 8:00 AM or 10:00 PM.

[0044] It should be noted that the current plant species can be understood as the plant category, and growth habits can be understood as various information about this type of plant during its growth process, including its requirements for environmental temperature and humidity, and the light intensity required for maximum photosynthetic efficiency at different growth stages. For ease of understanding, the light flux density of different spectra required for maximum photosynthetic efficiency at different growth stages is denoted as growth light. Growth status can be understood as the real-time growth status of the currently planted plant. For example, growth habits include the temperature and humidity requirements and the light intensity required for photosynthesis corresponding to the seedling stage, seedling stage, growth stage, flowering stage, and fruiting stage. Growth status refers to the current growth stage of the plant, that is, one of the seedling stage, seedling stage, growth stage, flowering stage, and fruiting stage.

[0045] It is important to note that the principle of plant grow lights is as follows: based on the light intensity value required for plant photosynthesis and the light intensity value already existing in the current environment, the light intensity difference between the two is calculated. This light intensity difference is the light intensity value that the plant grow light needs to provide in order to meet the light intensity requirements for plant growth.

[0046] Based on this principle, this embodiment generates first reference light intensity information based on environmental parameter information, and second reference light intensity information based on plant-related information and environmental parameter information; then, it generates operating parameters for the light source based on the first and second reference light intensity information; the control drive circuit adjusts the relevant parameters of multiple light sources of different wavelengths according to the operating parameters. Specifically, the control unit can obtain the operating parameters of the light source based on the existing light intensity in the environment and the light intensity corresponding to the highest photosynthetic efficiency in the current growth stage of the plant. Specifically, by calculating the difference between the light intensity required by the plant and the existing light intensity in the environment, the light intensities of the first and second wavelength lasers required by the light source can be obtained, and then the operating parameters of the light source can be obtained through conversion, and the relevant parameters of the light source can be adjusted according to the operating parameters of the light source.

[0047] This embodiment comprehensively considers plant-related information and environmental parameters to obtain first and second reference light intensity information. Based on this information, the operating parameters of the light source are then determined, ultimately achieving adjustment of the light intensity of the first and second wavelength lasers. Compared to existing methods that directly use ambient light as a reference for adjusting plant supplemental lighting, this embodiment further considers the plant species and the optimal light intensity required for photosynthesis at different growth stages. It also considers the impact of environmental temperature and humidity on plant photosynthetic efficiency and the wavelength loss during transmission of the first and second wavelength lasers. This allows for adjustment of both wavelengths, resulting in a more superior adaptive adjustment of the entire laser plant control device, further optimizing light source control, achieving excellent plant supplemental lighting effects, and reducing energy consumption.

[0048] In some embodiments, the first reference light intensity information includes the intensity change value of ambient light within a preset period range, the second reference light intensity information includes the intensity change value of growth light within a preset period range, and the environmental parameter information includes time information.

[0049] The operating parameters of the light source generated based on the first reference light intensity information and the second reference light intensity information include:

[0050] Based on the current time information, obtain the intensity value of the ambient light in the current first reference light intensity information, and based on the current time information, obtain the intensity value of the growth light in the current second reference light intensity information;

[0051] Calculate the difference between the intensity of ambient light and the intensity of growth light;

[0052] The intensity values ​​of the first band laser and the second band laser are generated based on the difference.

[0053] The operating parameters of the light source are calculated based on the intensity values ​​of the first and second band lasers.

[0054] In this embodiment, the first reference light intensity information can be understood as a discrete point data set, which includes the intensity variation values ​​of ambient light within a preset period range. Similarly, the second reference light intensity information can be understood as another independent discrete point data set, which includes the intensity variation values ​​of growth light within a preset period range.

[0055] In this embodiment, the preset period range is preferably 24 hours, that is, a whole day is used as the smallest unit of measurement. This method is more in line with the growth habits of plants and also conforms to the changing cycle of ambient light in the planting area.

[0056] Specifically, based on the current time information, the intensity value of ambient light in the current first reference light intensity information is obtained; based on the current time information, the intensity value of growth light in the current second reference light intensity information is obtained; the difference between the intensity value of ambient light and the intensity value of growth light corresponding to this time information is calculated; and the intensity values ​​of the first band laser and the second band laser are generated based on the difference. It should be noted that the difference includes the light difference of the first band and the light difference of the second band, which also correspond to the intensity values ​​of the first band laser and the second band laser in the laser plant control device.

[0057] In some embodiments, the environmental parameter information includes temperature information and humidity information;

[0058] The generation of second reference light intensity information based on plant-related information and environmental parameters also includes:

[0059] Obtain plant-related information and generate the first growth light reference value for the current plant at the current growth stage based on the plant-related information;

[0060] Acquire current visual sensor information, timer information, temperature information, and humidity information, and generate a second growth light reference value for the plant at the current growth stage based on the current visual sensor information, current timer information, current temperature information, and current humidity information;

[0061] The second reference light intensity information is generated based on the first growth light reference value and the second growth light reference value.

[0062] It should be noted that temperature information affects the efficiency of photosynthesis, while humidity information affects the energy loss of the first and second wavelengths of light during transmission through the air. Therefore, the generation of the second reference light intensity information needs to comprehensively consider the impact of current temperature on photosynthetic efficiency, as well as the intensity loss of ambient light caused by current humidity.

[0063] In this embodiment, the first growth light reference value refers to the growth light corresponding to the plant's highest photosynthetic efficiency under ideal environmental conditions, and the second growth light reference value refers to the growth light corresponding to the plant's highest photosynthetic efficiency under actual environmental conditions.

[0064] The second reference light intensity information is generated based on the first growth light reference value and the second growth light reference value. Specifically, the first growth light reference value and the second growth light reference value can be weighted and calculated (for example, if a plant needs light with a wavelength of 660nm and light with a wavelength of 450nm for growth, and the weight ratio of the luminous flux density corresponding to the two wavelengths is 3:7, then the second reference light intensity information can be generated based on the corresponding weight ratio of the first growth light reference value and the second growth light reference value), thereby obtaining the second reference light intensity information.

[0065] This embodiment takes into account the influence of current environmental humidity and temperature information on the second reference light intensity information. The calculated second reference light intensity information is more in line with the actual environment, thereby realizing the precise adjustment of the supplementary light intensity of the laser plant control device.

[0066] In some embodiments, calculating the difference between the intensity value of ambient light and the intensity value of growth light includes:

[0067] The intensity value of the ambient light within the first wavelength range is obtained and recorded as the first intensity value. The intensity value of the growth light within the first wavelength range is obtained and recorded as the second intensity value. The first intensity value and the second intensity value are subtracted to obtain the difference in the first wavelength range.

[0068] The intensity value of the ambient light within the second band range is obtained and recorded as the third initial value. The intensity value of the growth light within the second band range is also obtained and recorded as the fourth initial value. The third initial value and the fourth initial value are subtracted to obtain the second band difference.

[0069] The intensity values ​​of the first and second band lasers are generated based on the difference, including:

[0070] The difference in the first band is used as the intensity value of the laser in the first band;

[0071] The difference in the second band is used as the intensity value of the laser in the second band.

[0072] In this embodiment, based on the principle of photosynthesis, plants have the highest photosynthetic efficiency within the first and second wavelength ranges. Therefore, the laser plant control device is mainly used to adjust the light intensity corresponding to the first and second wavelength ranges. Further, the intensity value of the ambient light within the first wavelength range is acquired and recorded as the first intensity value; the intensity value of the growth light within the first wavelength range is acquired and recorded as the second intensity value; the first intensity value and the second intensity value are subtracted to obtain the first wavelength difference. Similarly, the intensity value of the ambient light within the second wavelength range is acquired and recorded as the third initial value; the intensity value of the growth light within the second wavelength range is acquired and recorded as the fourth initial value; the third initial value and the fourth initial value are subtracted to obtain the second wavelength difference. Correspondingly, the first wavelength difference is also the intensity value of the first wavelength laser in the laser plant control device, and the second wavelength difference is also the intensity value of the second wavelength laser in the laser plant control device.

[0073] In some embodiments, the preset period range is 24 hours.

[0074] In some embodiments, the operating parameters of the light source include the laser output power during continuous output, or the peak power, pulse width, and repetition frequency during pulse output.

[0075] In a third aspect, this embodiment also provides a computer-readable storage medium storing computer program instructions thereon, which, when executed by a processor, implement the method described in the second aspect.

[0076] In the above technical solution, the laser plant control device includes a base, a light homogenizer, a control unit, a light source, a driving circuit, a communication unit, and a sensing component. The control unit is electrically connected to the light source, the driving circuit, the communication unit, and the sensing component. The sensing component is used to collect environmental parameter information, the communication unit is used to acquire plant-related information, the driving circuit is electrically connected to the light source, and the control unit is used to generate first reference light intensity information based on the environmental parameter information, and second reference light intensity information based on the plant-related information and environmental parameter information; and to generate operating parameters of the light source based on the first and second reference light intensity information; the control driving circuit adjusts the relevant parameters of multiple light sources of different wavelengths according to the operating parameters. This technical solution realizes the adjustment of the relevant parameters of the light source based on environmental parameter information and plant-related information, thereby achieving the light intensity adjustment effect of the first and second wavelength lasers. It can comprehensively consider the different growth stages of the plant and the environmental factors in the current environment to adjust the output of the light source in the laser plant control device, reduce the energy consumption of the entire laser plant control device, and is more in line with the plant's growth state, thereby improving the plant's growth rate.
