Description

Technical Field

[0001] The present invention relates to the field of laser agricultural lighting equipment, and in particular to a laser plant control device, a control method and a medium. 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] Although the existing plant fill light has the function of light intensity regulation, it mainly relies on manual adjustment and cannot be adaptively adjusted according to environmental changes. The ambient temperature and humidity, ambient light intensity, etc. all affect the absorption of light by plants during their growth process. 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 accordingly 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 light saturation. 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.

[0004] According to existing research, different laser bands require different light intensities for laser regulation of different plant growth cycles, and different bands of laser light intensity need to be controlled according to ambient light and plant growth stages. The regulation of plant physiological cycles by lasers is very obvious in experiments, but in order to prevent light waste, feedback regulation of laser light intensity is required to supplement light intensity in accordance with plant growth stages.

In the following description, the same modules are represented by the same reference numerals. In the case of the same reference numerals, their names and functions are also the same. Therefore, the detailed description thereof will not be repeated.

[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. 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.

[0021] See also Figure 1 and Figure 2 In the first aspect, the present embodiment provides a laser plant control device 14, including a base 12, a light homogenizer 1, a control unit 6, a light source, a driving circuit, a communication unit 7 and a sensor component, wherein the base 12 includes a housing cavity and a light through hole, and the light through hole is connected to the housing cavity; the light homogenizer 1 is arranged at the light through hole; the light source is arranged in the housing cavity, and the output end of the light source is arranged toward the light homogenizer 1, and the light source is used to output lasers of multiple different bands, preferably, the laser includes a first band laser and a second band laser; the driving circuit is arranged in the housing cavity, and is electrically connected to the light source and the control unit 6 respectively, and the driving circuit is used to adjust the relevant parameters of the light source according to the control command of the control unit 6; the communication unit 7 is arranged in the housing cavity, and the communication unit 7 is electrically connected to the control unit 6, and the communication unit 7 is used to establish a communication connection with the server to obtain plant-related information; the sensor component is arranged in the housing cavity, and the sensor component is used to collect environmental parameter information, and the sensor component is electrically connected to the control unit 6; the control command of the control unit 6 includes the operating parameters of the light source, and the operating parameters are generated according to the plant-related information and / or the environmental parameter information.

[0022] 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 planting area, and plants 15 are planted in the planting area.

[0023] The light source is a laser. Specifically, the light source can be a dual-frequency laser or a single-frequency laser. 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 repetitive pulse lasers with a certain amplitude, frequency and pulse width.

[0024] In this embodiment, the first band laser and the second band laser correspond to the light waves of the bands required for photosynthesis of the plant 15. For example, the first band can be understood as the band interval where red light is located, and the second band can be understood as the band interval where blue light 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.

[0025] 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, etc. Optionally, the communication unit 7 may also establish a connection with a preset terminal 13 for communicating with the preset terminal 13. The preset terminal 13 may be a mobile phone, a tablet, a laptop, etc., or an infrared remote controller, which may be adjusted according to actual needs.

[0026] The communication unit 7 is used to collect plant-related information, which refers to the relevant information of the plants 15 planted in the current 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.

[0027] The sensor component is used to collect environmental parameter information, which includes the temperature and humidity information of the environment and the existing light intensity in the environment.

[0028] The control command of the control unit 6 includes the operating parameters of the light source. Here, it can be understood that the light source and the driving circuit work together to generate the first-band laser and the second-band laser, and the operating parameters of the light source correspond to the adjustment of the light source and the adjustment of the driving circuit. The operating parameters are generated according to the plant-related information and / or environmental parameter information. Specifically, the control unit 6 can obtain the operating parameters of the light source according to the existing light intensity in the environment and the light intensity corresponding to the highest photosynthesis efficiency of the plant 15 in the current growth stage. Specifically, the difference between the light intensity required by the plant 15 and the existing light intensity in the environment is calculated, and the light intensity of the first-band laser and the second-band laser required to be output by the light source can be obtained, and then the operating parameters of the light source are obtained by conversion.

[0029] See also 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.

[0030] In this embodiment, the light source includes a first light source 2 and a second light source 3 arranged in parallel. Here, the parallel arrangement refers to the parallel arrangement corresponding to the light port, 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 the first band, which is recorded as the first band laser, and the second light source 3 can generate a laser of the second band, which is recorded as the second band 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. 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.

[0031] In some embodiments, the sensing component includes any one of a temperature sensor, a humidity sensor, a visual sensor, a spectral sensor, and a timer. In this embodiment, the temperature sensor is used to collect the ambient temperature information of the current planting area; the humidity sensor is used to collect the ambient humidity information of the current planting area; the visual sensor is used to collect the image information of the current planting area, and extract the image data of the plant 15 in the current planting area according to the image information, and determine the growth stage of the current plant 15 according to the image data of the plant 15; the spectral sensor is used to collect the ambient light information of the current planting area, and the ambient light information includes the light intensity of the first band and the light intensity of the second band in the environment.

[0032] It should be noted that the timer is used to synchronize the current time data. 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 time data of the timer.

[0033] As a preferred embodiment, a power supply unit 11 and a DC voltage regulator module 10 may also be included. The laser plant control device of the present invention may be powered by an AC power supply or a DC power supply. When a DC power supply is connected, the power supply unit 11 may be a lithium battery, a lead-acid battery, a solar panel, etc. When an AC power supply is used, the DC voltage regulator module 10 may 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. Figure 2 The power supply unit 11 is shown as a 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.

[0034] As another preferred embodiment, it can also include a first display unit 8 and a second display unit 9, which are arranged on the outside of the base 12, and 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, and 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 easy for users to directly check the fill light status of the fill light device.

[0035] See also Figure 3 In a second aspect, this embodiment further provides a laser plant control method, which is applicable to the laser plant control device described in the first aspect, and the method includes: S11, obtaining environmental parameter information and plant-related information, the environmental parameter information including at least one of temperature information, humidity information, light information and time information, and the plant-related information including the growth type, growth habit and growth status of the currently planted plants; S12, generating first reference light intensity information according to the environmental parameter information, and generating second reference light intensity information according to the plant related information and the environmental parameter information; S13, generating operating parameters of the light source according to the first reference light intensity information and the second reference light intensity information; S14, controlling the driving circuit to adjust relevant parameters of a plurality of light sources of different wavelength bands according to the operating parameters.

[0036] In this embodiment, the environmental parameter information refers to the temperature information, humidity information, light information and time information of the environment where 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. The time information is the current time data, for example, the time information is 8 am, 10 pm, etc.

[0037] It should be noted that 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 for the highest photosynthetic efficiency in different growth stages, etc. For ease of understanding, the light flux density of different spectra required for the highest photosynthetic efficiency in different growth stages is recorded as growth light; the growth state can be understood as the real-time growth state of the currently planted plants. For example, the growth habits include the temperature and humidity requirements corresponding to the plants in the seedling period, seedling pulling period, growth period, flowering period, and fruiting period, the light intensity required for photosynthesis, etc. The growth state refers to the current growth stage of the plant, that is, one of the seedling period, seedling pulling period, growth period, flowering period, and fruiting period.

[0038] It should be noted that the principle of plant fill light is: according to 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 also the light intensity value that the plant fill light needs to provide in order to achieve the light intensity requirements for plant growth.

[0039] Based on this principle, this embodiment generates first reference light intensity information according to environmental parameter information, generates second reference light intensity information according to plant-related information and environmental parameter information; then generates operating parameters of the light source according to the first reference light intensity information and the second reference light intensity information; and controls the driving circuit to adjust 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 according to the existing light intensity in the environment and the light intensity corresponding to the highest photosynthesis efficiency in the current growth stage of the plant. Specifically, the difference between the light intensity required by the plant and the existing light intensity in the environment can be calculated to obtain the light intensity of the first-band laser and the second-band laser that the light source needs to output, and then the operating parameters of the light source are obtained by conversion, and then the relevant parameters of the light source are adjusted according to the operating parameters of the light source.

[0040] This embodiment comprehensively considers plant-related information and environmental parameter information, and then obtains first reference light intensity information and second reference light intensity information, and then obtains the operating parameters of the light source based on the first reference light intensity information and the second reference light intensity information, and finally achieves the adjustment of the light intensity of the first-band laser and the second-band laser. Compared with the existing principle of adjusting plant fill light directly based on ambient light as a reference, this embodiment further considers the type of plant and the light intensity required for optimal photosynthesis at different growth stages. At the same time, it also considers the impact of environmental temperature and humidity factors on plant photosynthetic efficiency and the wavelength loss of the first-band laser and the second-band laser during transmission, thereby achieving the adjustment of the first-band laser and the second-band laser, so that the entire laser plant control device has a more superior adaptive adjustment, further optimizes the light source control, achieves a good plant fill light effect, and reduces energy consumption.

[0041] In some embodiments, the first reference light intensity information includes an intensity change value of the ambient light within a preset period range, the second reference light intensity information includes an intensity change value of the growth light within a preset period range, and the environmental parameter information includes time information; Generating the operating parameters of the light source according to the first reference light intensity information and the second reference light intensity information includes: Obtaining the intensity value of the ambient light in the current first reference light intensity information according to the current time information, and obtaining the intensity value of the growth light in the current second reference light intensity information according to the current time information; Calculate the difference between the intensity of the ambient light and the intensity of the growth light; Generate an intensity value of the laser light of the first wavelength band and an intensity value of the laser light of the second wavelength band according to the difference; The operating parameters of the light source are calculated according to the intensity value of the laser in the first wavelength band and the intensity value of the laser in the second wavelength band.

[0042] In this embodiment, the first reference light intensity information can be understood as a discrete point data set, which includes the intensity change value of the ambient light within a preset period range. Similarly, the second reference light intensity information can also be understood as another independent discrete point data set, which includes the intensity change value of the growth light within a preset period range.

[0043] In this embodiment, the preset cycle range is preferably 24 hours, that is, a whole day is used as the minimum measurement unit. This method is more in line with the growth habits of plants and also fits the changing cycle of ambient light in the planting area.

[0044] Specifically, the intensity value of the ambient light in the current first reference light intensity information is obtained according to the current time information, the intensity value of the growth light in the current second reference light intensity information is obtained according to the current time information, the difference between the intensity value of the ambient light and the intensity value of the growth light corresponding to this time information is calculated, and the intensity value of the first band laser and the intensity value of the second band laser are generated according to 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 corresponds to the intensity value of the first band laser and the intensity value of the second band laser in the laser plant control device.

[0045] In some embodiments, the environmental parameter information includes temperature information and humidity information; Generating the second reference light intensity information according to the plant related information and the environmental parameter information also includes: Acquire plant related information, and generate a first growth light reference value of the current plant in the current growth stage according to the plant related information; Acquire current visual sensor information, timer information, temperature information, and humidity information, and generate a second growth light reference value of the plant in the current growth stage according to the current visual sensor information, the current timer information, the current temperature information, and the current humidity information; Second reference light intensity information is generated according to the first growing light reference value and the second growing light reference value.

[0046] It should be noted that temperature information affects the efficiency of photosynthesis, and humidity information affects the energy loss of the light of the first band and the light of the second band when they are transmitted in the air. Based on this, the generation of the second reference light intensity information needs to comprehensively consider the impact of the current temperature on the photosynthetic efficiency and the intensity loss of the ambient light caused by the current humidity.

[0047] In this embodiment, the first growth light reference value refers to the growth light corresponding to the highest photosynthesis efficiency of the plant under ideal environmental conditions, and the second growth light reference value refers to the growth light corresponding to the highest photosynthesis efficiency of the current plant under actual environmental conditions.

[0048] The second reference light intensity information is generated according to 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 weightedly calculated (for example, a certain plant needs light with a wavelength of 660nm and light with a wavelength of 450nm, and the weight ratio of the luminous flux density corresponding to the two wavelengths of light is 3:7, then the second reference light intensity information can be generated according to 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.

[0049] This embodiment comprehensively considers the influence of the humidity information and temperature information of the current environment on the second reference light intensity information, and the calculated second reference light intensity information is more in line with the actual environment, thereby realizing the precise fill light intensity adjustment of the laser plant control device.

[0050] In some embodiments, calculating the difference between the intensity value of the ambient light and the intensity value of the growth light includes: Obtaining the intensity value of the ambient light in the first wavelength range from the ambient light, recorded as the first intensity value, and obtaining the intensity value of the growth light in the first wavelength range from the growth light, recorded as the second intensity value, performing a subtraction operation on the first intensity value and the second intensity value to obtain a first wavelength difference; Obtaining the intensity value of the ambient light in the second wavelength range in the ambient light, recording it as the third initial value, and obtaining the intensity value of the growth light in the second wavelength range in the growth light, recording it as the fourth initial value, performing a subtraction operation on the third initial value and the fourth initial value to obtain a second wavelength difference; Generating the intensity value of the first-band laser and the intensity value of the second-band laser according to the difference includes: The difference value of the first waveband is used as the intensity value of the laser of the first waveband; The second band difference is used as the intensity value of the second band laser.

[0051] In this embodiment, based on the principle of photosynthesis, the photosynthetic efficiency of plants is the highest in the first band range and the second band range, and the laser plant control device is mainly used to adjust the light intensity corresponding to the first band range and the second band range. Further, the intensity value of the ambient light in the first band range in the ambient light is obtained, recorded as the first intensity value, the intensity value of the growth light placed in the first band range in the growth light is obtained, recorded as the second intensity value, and the first intensity value and the second intensity value are subtracted to obtain the first band difference; the intensity value of the ambient light placed in the second band range in the ambient light is obtained, recorded as the third initial value, and the intensity value of the growth light placed in the second band range in the growth light is obtained, recorded as the fourth initial value, and the third initial value and the fourth initial value are subtracted to obtain the second band difference. Correspondingly, the first band difference is also the intensity value of the first band laser in the laser plant control device, and the second band difference is also the intensity value of the second band laser in the laser plant control device.

[0052] In some embodiments, the preset period range is 24 hours.
