Description

Technical Field

[0001] The present invention relates to the field of laser agricultural lighting equipment, and in particular to an adaptive laser plant fill light lamp, a fill light method and a medium based on spectral analysis. Background Art

[0002] Plant fill lights use the principle of semiconductor lighting and are used to assist the growth of crops, flowers, vegetables and other plants. Generally, greenhouse crops and indoor plants and flowers will grow worse and worse over time. The main reason is the lack of light exposure. By irradiating with light sources suitable for the spectrum required by plants, their growth can be promoted, the yield can be increased, and the quality of crops can be improved. Applying plant fill lights to agricultural facilities such as greenhouses can, on the one hand, solve the problem of insufficient sunlight leading to reduced yield and quality. On the other hand, it can also make greenhouse fruits and vegetables in winter go on the market earlier, thereby achieving the purpose of off-season cultivation.

[0003] Light formula is the key to plant supplementary lighting. The spectral composition and its irradiation intensity largely determine the degree of influence of supplementary lighting on plant growth, and ultimately affect the yield and quality of crops. There are two key points in plant photosynthesis, namely the light compensation point and the light saturation point. When the light compensation point is reached, the photosynthetic rate increases with the increase of light intensity. When a certain light intensity is reached, the photosynthetic rate no longer increases with the increase of light intensity, that is, it reaches the light saturation phenomenon. At this time, if the external light intensity is greater than the light saturation point of the plant, the plant will not absorb more light, which will result in a waste of light. Although the existing plant supplementary lighting has the function of light intensity regulation, it mainly relies on manual adjustment and cannot be adaptively adjusted according to environmental changes, which has limited use.

It should be understood that the specific embodiments described herein are only used to explain the present invention and do not constitute a limitation of the present invention.

[0020] See also Figure 1 and Figure 2 In the first aspect, the present embodiment provides an adaptive laser plant fill light 14 based on spectral analysis, which is arranged in a plant planting area, including a base 12 and a light source component, a homogenizing component, a control component and a spectral analysis component arranged on the base 12; the light source component includes a plurality of light sources arranged in parallel, and the plurality of light sources emit lasers of different bands, one of the light sources is referred to as a first light source 2, and the other light source is referred to as a second light source 3, the first light source 2 and the second light source 3, the first light source 2 is used to emit a first-band laser, and the second light source 3 is used to emit a second-band laser; the homogenizing component includes a homogenizing element 1, the homogenizing element 1 is arranged at the output ends of the first light source 2 and the second light source 3, and the homogenizing element 1 is used to homogenize the first-band laser and the second-band laser and then project them to the plant planting area; the spectral analysis The analysis component includes a spectrum collection end and a spectrum analysis unit, the spectrum collection end is electrically connected to the spectrum analysis unit, the spectrum collection end is set toward the external environment, the spectrum collection end is used to collect the ambient spectrum in the ambient light within a preset band (i.e., the spectrum band that plants can use), the ambient spectrum includes the first band ambient light and the second band ambient light, the spectrum analysis unit is used to calculate the first ratio value of the first band ambient light to the second band ambient light; the control component includes a control unit 6, the control unit 6 is electrically connected to the first light source 2, the second light source 3, the spectrum analysis unit and the spectrum collection end, the control unit 6 is used to calculate the second ratio value of the first band laser and the second band laser according to the first ratio value, and adjust the operating parameters of the first light source 2 and the second light source 3 according to the second ratio value.

[0021] 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, or a frame, a rack, etc. The base 12 includes a housing cavity, and the control unit 6, the light source, the driving circuit and the communication unit 7 can all be arranged in the housing cavity. A light through hole is also provided on the base 12, and the light through hole is connected to the housing cavity. The light homogenizer 1 is arranged at the light through hole. Specifically, the light homogenizer 1 can be a combination of multiple optical lenses, or it can be a whole. This embodiment does not limit the light homogenizer 1. The light homogenizer 1 is used to evenly disperse the first-band laser and the second-band laser output by the light source into the plant planting area, and plants 15 are planted in the plant planting area.

[0022] The light source is a laser. Specifically, since different wavelengths of light have different effects on the photosynthesis of the plant 15, and 400-520nm blue light and 610-720nm red light contribute the most to photosynthesis, this embodiment preferably includes a laser with two wavelengths, red and blue; the first band can be understood as the band interval where the red light is located, and the second band can be understood as the band interval where the blue light band is located. Specifically, the specific band intervals of the first band and the second band can be further set according to the type of plant 15 to meet the photosynthesis requirements of different types of plants 15.

[0023] In this embodiment, the light source includes a first light source 2 and a second light source 3 arranged in parallel, and the parallel arrangement here means that the light homogenizer 1 is arranged in parallel, so that the light homogenizer 1 can homogenize the first light source 2 and the second light source 3 at the same time. The first light source 2 can generate a laser of a first wavelength band, which is recorded as a first wavelength band laser, and the second light source 3 can generate a laser of a second wavelength band, which is recorded as a second wavelength band laser.

[0024] The spectrum analysis component includes a spectrum analysis unit and a spectrum collection end. Preferably, the spectrum analysis component can be a whole, such as a detector, specifically a CCD detector. The spectrum collection end is also the collection end of the detector, and the spectrum analysis unit is also the analysis and calculation module built into the detector. The spectrum analysis unit can calculate a first ratio value of the first band ambient light to the second band ambient light, that is, the first ratio value = the luminous flux density of the first band ambient light: the luminous flux density of the second band ambient light.

[0025] It should be noted that the principle of the plant fill light 14 is: according to the light intensity value required for photosynthesis of the plant 15 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 also the light intensity value that the plant fill light 14 needs to provide, so as to meet the light intensity requirement required for the growth of the plant 15. Based on this, the control unit 6 is used to calculate the second ratio value of the first band laser and the second band laser according to the first ratio value, and adjust the operating parameters of the first light source 2 and the second light source 3 according to the second ratio value. It can be understood that the control unit 6 can pre-acquire the preset ratio value of the first band light and the second band light required by the current plant 15 at this growth stage, and then combine the first ratio value corresponding to the existing ambient light to calculate the second ratio value corresponding to the first band laser and the second band laser, and adjust the operating parameters of the first light source 2 and the second light source 3 according to the second ratio value. For the convenience of description, the light of the first band and the light of the second band are referred to as red and blue light. For example, for a certain crop, the expected intensity ratio of red and blue light irradiation is 5M:1M, where M is the light power per unit area. If the actual measured ratio of red and blue light in the ambient light is 2.5M:0.5M, then the intensity ratio of red and blue light output by the fill light should be 2.5M:0.5M.

[0026] It should be noted that the light formula is the key to the plant fill light 14. The spectral composition and its irradiation intensity largely determine the degree of influence of the fill light on the growth of the plant 15, and ultimately affect the yield and quality of the crop. Monitor the intensity of the red and blue light components in the ambient light, and then dynamically adjust the output intensity of the red and blue light according to a certain algorithm to achieve the purpose of optimizing the fill light. In this embodiment, the spectral analysis component can use the AS7262 six-channel visible light multi-spectral sensor. The six visible channels include 450nm, 500nm, 550nm, 570nm, 600nm, and 650nm, each with a FWHM (full width at halfmaxima) of 40nm; therefore, the first and sixth channels can be used to measure the intensity of blue and red light in the plant fill light 14, respectively.

[0027] The plant fill light 14 shown in this embodiment can be used outdoors as well as in light-transmitting greenhouses and greenhouses. In order to make a single plant fill light 14 evenly cover a large area of ​​crops, the plant fill light 14 needs to be installed at a high position several meters above the ground. The wireless remote control can provide great convenience for turning the device on and off, adjusting parameters, etc.

[0028] Compared with the existing LED plant fill light 14, this embodiment adopts a monochromatic light source (laser) working in a low duty cycle repetitive pulse mode, which can not only more effectively improve the photosynthesis rate of the plant 15 than a continuous wide-spectrum LED fill light, but also greatly reduce the power consumption of the fill light itself. It does not need to be powered by AC power, but can be powered by solar energy (including built-in lithium batteries) for all-weather fill light. It can not only provide day and night fill light on sunny days, but can even work continuously for several days on rainy days. It not only saves AC electricity bills, but also avoids the need to set up a power supply grid.

[0029] See also Figure 1 In some embodiments, the light source assembly further includes a plurality of driving circuits, and the plurality of driving circuits are used to drive different light sources to generate lasers of a plurality of wavelength bands. One of the driving circuits is referred to as a first driving circuit 4, and / or the other driving circuit is referred to as a second driving circuit 5. The first driving circuit 4 is electrically connected to the first light source 2, and the first driving circuit 4 is also electrically connected to the control unit 6. The first driving circuit 4 is used to adjust the operating parameters of the first light source 2 according to a first operating command of the control unit 6 to adjust the pulse amplitude of the laser of the first wavelength band; the second driving circuit 5 is electrically connected to the second light source 3, and the second driving circuit 5 is also electrically connected to the control unit 6. The second driving circuit 5 is used to adjust the operating parameters of the second light source 3 according to a second operating command of the control unit 6 to adjust the pulse amplitude of the laser of the second wavelength band; the first operating command and the second operating command are generated according to the second proportional value.

[0030] Continuous light with a constant amplitude is not the best for promoting photosynthesis in plants 15, but repeated light pulses with a certain frequency can effectively increase the rate of photosynthesis and significantly reduce the power consumption of the plant light 14 device itself. The photosynthesis process of plants 15 is to first perform a light reaction and then a dark reaction. The speed of the light reaction is in the order of microseconds, and the speed of the dark reaction is in the order of milliseconds. Therefore, pulsed lasers can be used to promote photosynthesis in plants 15 and achieve further energy saving.

[0031] Based on this, the present embodiment adds a driving circuit, the driving circuit is electrically connected to the light source, the driving circuit is a semiconductor laser pulse driving circuit, the driving circuit can drive the light source to generate a repetitive pulse laser with a certain amplitude, frequency and pulse width, and the repetitive pulse laser can increase the photosynthesis rate of the plant 15 and reduce the energy loss of the light source. Accordingly, 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. Then the control unit 6 controls the first driving circuit 4 and the second driving circuit 5 respectively to adjust the first band laser and the second band laser.

[0032] See also Figure 1 In some embodiments, the control component also includes a display unit, which includes a first display 8, which is electrically connected to the control unit 6 and is used to display the operating parameters of the first light source 2; and / or includes a second display 9, which is electrically connected to the control unit 6 and is used to display the operating parameters of the second light source 3.

[0033] The first display 8 and the second display 9 are arranged on the outside of the base 12. The first display 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 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 easy for users to directly check the fill light status of the plant fill light 14.

[0034] See also Figure 1 In some embodiments, the control component also includes a communication unit 7, which is electrically connected to the control unit 6 and is used to send the operating parameters of the first light source 2 and the second light source 3 to the preset terminal 13, and / or to receive control instructions issued by the preset terminal 13. The control unit 6 is also used to adjust the operating parameters of the first light source 2 and the second light source 3 according to the control instructions sent by the preset terminal 13.

[0035] The communication unit 7 may be different according to different communication connection modes in actual applications. For example, the communication unit 7 may be an NB-IoT Internet of Things communication device, or a Bluetooth communication device, a Star Flash communication device, a WIFI communication device, or a 4G network standard communication device. The communication unit 7 may also establish a connection with the preset terminal 13 for communicating with the preset terminal 13. For example, when the preset terminal 13 is an infrared remote controller, the communication unit 7 is an infrared sensor unit.

[0036] The communication unit 7 is used to collect plant 15 related data. The plant 15 related data refers to the relevant information of the plants 15 planted in the current plant planting area, including the type of plant 15, the current growth stage of the plant 15 and the light intensity required by the plant 15 in this growth stage. Specifically, the light intensity refers to the band range and light wave intensity of the light wave corresponding to the highest photosynthesis efficiency of this plant 15.

[0037] In some embodiments, the preset terminal 13 is one of a remote controller, a mobile phone, a tablet, and a computer. The preset terminal 13 can be a mobile phone, a tablet, a laptop, etc., or an infrared remote controller, which is adjusted according to actual needs.

[0038] In some embodiments, a timer is further included, and the timer is electrically connected to the control unit 6, and the control unit 6 is used to adjust the operating parameters of the first light source 2 and / or the second light source 3 according to the first time signal output by the timer. It should be noted that the timer is used to output the first time signal, and the first time signal is the current real time. The photosynthesis rate of the plant 15 is different during the day and at night, and the light intensity in the environment is also different. Therefore, adding a timer facilitates the control unit 6 to adjust the first band laser and the second band laser according to the first time signal of the timer.

[0039] As a preferred embodiment, the plant fill light 14 may further include a power supply unit 11 and a DC voltage stabilizing module 10. The power supply unit 11 may be a lithium battery, a lead-acid battery, a solar panel, etc. Preferably, the power supply unit 11 is in the form of a combination of a solar panel and a lithium battery, that is, the solar panel has a built-in lithium battery. The power supply unit 11 shown in this embodiment is combined with the plant fill light 14, and all-weather fill light can be provided by relying on solar power supply (including a built-in lithium battery). Not only can fill light be provided day and night on sunny days, but it can even work continuously for several days on rainy days.

[0040] The adaptive laser plant light based on spectral analysis of the present invention can be powered by an AC power supply or a DC power supply. When connected to an AC power supply, the DC voltage regulator module 10 can be used to convert the AC power into a DC power for use by the control unit 6, the drive circuit and the light source. When a DC power supply is used, Figure 2It is specifically shown that the power supply unit 11 is in the form of 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 arranged outside the base 12 and facing south. Preferably, the angle between the solar panel surface and the horizontal plane should correspond to the local latitude.

[0041] In some embodiments, an insecticidal lamp and / or an insect repellent lamp 16 is also included, and the insecticidal lamp and / or the insect repellent lamp 16 is electrically connected to the control unit 6, and the control unit 6 is used to control the opening and closing of the insecticidal lamp and / or the insect repellent lamp 16 according to the second time signal output by the timer. In this embodiment, the second time signal output by the timer can correspond to the time at night, or to the time in summer when there are more mosquitoes. By adding the insecticidal lamp and / or the insect repellent lamp 16, it is convenient to further maintain the plants 15 in the plant planting area.

[0042] As a preferred embodiment, the control unit 6 is also provided with a power monitoring function. Taking into account the power consumption of the insecticidal lamp and / or the insect repellent lamp 16, the control unit 6 can periodically measure the remaining power of the power supply unit 11. If the remaining power allows, the insecticidal lamp and / or the insect repellent lamp 16 is turned on and continues to work for a certain period of time. This method can further optimize the power control of the entire plant fill light 14 and reduce energy consumption.

[0043] In some embodiments, a sensing component is also included, the sensing component includes a temperature sensor, the temperature sensor is electrically connected to the control unit 6, the temperature sensor is used to collect ambient temperature information, and the control unit 6 is used to adjust the operating parameters of the first light source 2 and / or the second light source 3 according to the ambient temperature information; and / or, the sensing component includes a visual sensor, the visual sensor is electrically connected to the control unit 6, the visual sensor is used to collect growth images of plants 15 in the plant planting area, and the control unit 6 is used to adjust the operating parameters of the first light source 2 and / or the second light source 3 according to the growth images of the plants 15.

[0044] In this embodiment, the temperature sensor is used to collect the ambient temperature information of the current plant planting area, which can be used to add a limiting condition for fill light, that is, to stop the fill light when the ambient temperature is lower than a certain value, so as to avoid the fill light from working ineffectively at low temperatures; the visual sensor is used to collect image information of the current plant planting area, and extract image data of plants 15 in the current plant planting area based on the image information, and determine the growth stage of the current plant 15 based on the image data of the plant 15.

[0045] As a specific embodiment of practical application: the rated voltage and current of the 660nm first light source 2 is 1.9V / 2.1A; the rated voltage and current of the 450nm second light source 3 is 4.9V / 2.1A. The first drive circuit 4 and the second drive circuit 5 are designed for different volt-ampere characteristics, and the operating frequency of both is 300Hz, and the pulse width is 40μs; the intensity of the output power of the first light source 2 and the second light source 3 is adjustable from 0 to 9 levels, with no output at level 0 and increasing intensity from level 1 to 9. The infrared remote control (i.e., the preset terminal 13) includes 5 functions such as red light +, red light -, blue light +, blue light -, on / off, etc. The functions are intuitive and can realize the increase and decrease of the intensity of red and blue light, as well as the standby function. The plant supplementary light 14 is installed on a fixed frame 3 meters above the ground, and the remote control distance of the remote control is not less than 6 meters.

[0046] The power consumption estimation process of the entire plant fill light 14 is as follows: calculated based on the working frequency of 300Hz and the pulse width of 40μs, the cumulative light emission time per second is 300×40μs=12000μs, which is equivalent to 1.2% of the continuous light emission mode, and the power consumption of the whole machine is much lower than that of ordinary LED fill lights. The solar photovoltaic component (that is, the power supply unit 11) used in this embodiment is 140W / 70Ah: the working voltage of the photovoltaic panel is 15-18V, the peak output power is as high as 140W, the built-in lithium battery output voltage is 12V, and the capacity is 70 ampere hours. The average power consumption of the fill light when working is only 4.08W (12V0.34A). In the absence of light, a 70Ah lithium battery can provide a single fill light with 70Ah / 0.34A≈205h, which is about 8.5 days.

[0047] Furthermore, it also includes a 4G network camera for monitoring plant growth.

[0048] See also Figure 3 In a second aspect, the present embodiment further provides an adaptive laser plant fill light method, which is applicable to the adaptive laser plant fill light described in the first aspect, and the method includes: S11, obtaining an ambient spectrum collected by a spectrum collection end, and obtaining a first-band ambient light and a second-band ambient light according to the ambient spectrum; S12, the spectrum analysis unit is used to obtain a first intensity value of the ambient light in the first wavelength band and a second intensity value of the ambient light in the second wavelength band, and calculate a first ratio value according to the first intensity value and the second intensity value; S13, obtaining plant-related data and a preset ratio value of plants in the current plant planting area, where the preset ratio value is the ratio between the light intensity of the first band and the light intensity of the second band required by the plants in the current plant planting area during the growth stage; S14, calculating a second proportional value according to the preset proportional value and the first proportional value, the plant-related data including the current growth cycle of the plant and / or the growth habit of the plant, and the second proportional value is the ratio of the intensity value of the laser of the first wavelength band to the intensity value of the laser of the second wavelength band; S15, generating an adjustment control command according to the second ratio value, and adjusting operating parameters of the first light source and the second light source according to the adjustment control command, wherein the operating parameters of the first light source and the second light source include a third intensity value of the first-band laser and a fourth intensity value of the second-band laser.

[0049] In this embodiment, the ambient spectrum includes a first-band ambient light and a second-band ambient light, the first-band ambient light corresponds to a first intensity value, the second-band ambient light corresponds to a second intensity value, and a first ratio value is calculated based on the first intensity value and the second intensity value. In this embodiment, the first ratio value=first intensity value:second intensity value.

[0050] In this embodiment, the plant-related data includes the growth type, growth habits and growth status of the currently planted plants. The growth type of the currently planted plants can be understood as the category of plants, and the growth habits can be understood as various information of plants of this category during the growth process, including the temperature and humidity requirements of the environment, the light intensity required when the photosynthetic efficiency is the highest in different growth stages, etc. For ease of understanding, the light required when the photosynthetic efficiency is the highest in different growth stages is recorded as growth light; the growth status can be understood as the real-time growth status of the currently planted plants. For example, the growth habits include the temperature and humidity requirements corresponding to the plant in the seedling stage, the seedling pulling stage, the growth period, the flowering period, and the fruiting period, and the light intensity required for photosynthesis, etc. The growth status refers to the growth stage of the current plant, that is, one of the seedling stage, the seedling pulling stage, the growth period, the flowering period, and the fruiting period. Specifically, the preset ratio value is the ratio between the light intensity of the first band and the light intensity of the second band required by the current plant in the growth stage.

[0051] In this embodiment, the third intensity value is the light intensity of the first wavelength laser corresponding to the second proportional value, and the fourth intensity value is the light intensity of the second wavelength laser corresponding to the second proportional value.

[0052] The control unit can pre-acquire the preset ratio value of the first-band light and the second-band light required by the current plant at this growth stage, and then combine the first ratio value corresponding to the existing ambient light to calculate and obtain the second ratio value corresponding to the first-band laser and the second-band laser, and adjust the operating parameters of the first light source and the second light source according to the second ratio value. For ease of expression, the light of the first band and the light of the second band are referred to as red and blue light. For example, for a certain crop, the expected intensity ratio of red and blue light irradiation is 5M:1M, where M is the light power per unit area. If the actual measured ratio of red and blue light in the ambient light is 2.5M:0.5M, the intensity ratio of red and blue light output by the fill light should be 2.5M:0.5M.

[0053] This embodiment adjusts the operating parameters of the first light source and the second light source according to the ambient spectrum within a preset wavelength band in the ambient light collected by the spectrum collection end, thereby achieving intensity adjustment of the first light source and the intensity adjustment of the second light source, and achieving the effect of automatically adjusting the light intensity of the plant fill light according to the ambient light, so that the intensity of the light within the preset wavelength band in the environment where the plant is located can be maintained, which is conducive to the growth of the plant.
