Parameters such as the structure size material of the production area can be determined according to the production demands of different animals and plants, for example, small plants planted in the box or cultivated animal hatching eggs can be arranged into a growth area of a multi-layer splicing structure so as to fully utilize the space, and medium-sized and large-sized plants planted indoors or cultivated animals can be arranged into a single-layer tiling structure so as to ensure the growth space. Preferably, a soilless cultivation mode with controllable environment and higher yield can be adopted for the growing area of the plant, so that the growing area can ensure the cultivation environment required by the plant growth without depending on the microbial environment in the soil to provide nutrition for the plant.

According to a preferred embodiment, the illumination section 100 may be provided with at least one illumination unit, wherein each illumination unit can be provided with several monochromatic LED lamps with higher light conversion efficiency, so that more photons can be emitted than the composite light source at the same energy consumption, thereby reducing the energy consumption. Preferably, the illumination unit can be in a narrow-band structure, so that the length of the long side of the illumination unit is far longer than the length of the wide side of the illumination unit, and therefore dead angles of light irradiation of the illumination unit with narrow-band high light intensity are fewer when scanning is performed, more leaves on the macro scale can obtain light, cilia on the surfaces of plant leaves on the micro scale are reduced to be shielded, and light sensing organs on the leaf surfaces and the back sides of the leaves can also obtain more breeding opportunities. Further, the illumination unit of the illumination portion 100 can be driven by the light source moving unit to scan over the growing area to complete dynamic scanning of the light source, wherein the driving speed of the light source moving unit to the illumination unit is related to the species of animals and plants cultivated in the growing area, for example, for plants receiving photons with equal energy, the growth promoting effect of short-time high light intensity on the plants is better than that of long-time low light intensity on the plants. Preferably, the number of the illumination units can be determined based on the types of animals and plants cultivated in the growth area and the growth stages thereof, so as to regulate and control the illumination intensity, illumination time, illumination frequency and the like of the light received by the growth area, wherein plants are used as, for example, different plants have different light saturation points and light compensation points, when the light intensity exceeds the light saturation points, the effect of promoting the growth of the plants is not obvious, but the energy consumption is wasted, and when the light intensity is lower than the light compensation points, the growth speed of the plants is not improved and the growth is slow, so that the quality and the quantity of products are reduced. For example, the tomato may have a light saturation point of about 40000lux, a light compensation point of about 6000lux, and lettuce may have a light saturation point of about 20000lux, and a light compensation point of 2000lux, and the illumination scheme of the illumination unit 100 may be reasonably planned for the case of the growing area being cultivated or mixed.

Further, the illumination control unit 130 can provide various illumination strategies based on the mixing ratio of the light with different wavelengths, the light mixing mode and/or the light source power adjustment, and perform adaptive adjustment according to the ambient light and the animal and plant variety and the animal and plant growth stage. Specifically, the illumination units may be configured with the first illumination unit 110 and the second illumination unit 120 having different ground-leaving heights to avoid collision when the first illumination unit 110 and the second illumination unit 120 are moved under the driving of the light source moving unit, wherein the first illumination unit 110 and the second illumination unit 120 can emit light rays with the same or different wavelengths and intensities to adapt to the light receiving requirements of the growing area. Alternatively, the movement of the first and second illumination units 110 and 120 driven by the light source moving unit can be moved in the same direction or in opposite directions with a fixed or variable movement speed difference so that an optimal illumination scheme is obtained.

Further, the installation position or the moving fixed point position of the collecting part 200 can be determined according to the position of the light-transmitting plate 113 of the illuminating part 100 and the position of the growing area, so that the light emitted by the illuminating unit can be received by the collecting probe unit 220 without being blocked by the illuminating unit after being reflected by the surfaces of animals and plants in the growing area, thereby completing the acquisition of the growth condition information.

When the growing areas are in the shadow period, the illumination part 100 is in a non-working state, and the efficient operation of the device can be realized through the movement of the illumination part 100, so that the utilization rate of the device is improved, and the installation cost is reduced, wherein the illumination part 100 can move among different growing areas through the light source moving unit, the light source moving unit can comprise a light source pulley driven by a motor, and the light source pulley can be movably connected with a light source sliding rail arranged above the growing areas, so that the light source pulley moves on a limited track of the light source sliding rail under the driving of the motor, and the illumination part 100 is driven to move according to a preset track. For example, for a light period of about 8 to 20 hours per day for a plant of the family Solanaceae, a preferable light period is about 12 to 18 hours, i.e. a preferable shade period of about 6 to 12 hours per day for a plant of the family Solanaceae, and when both the light period and the ground shadow period are selected to be 12 hours, the light portion can complete a theoretically seamless alternation between the two growing regions, thereby achieving maximum utilization of the light portion 100. Further, to ensure the service life of the illumination portion 100, the illumination work of all the growing areas can be completed by a plurality of illumination portions 100 alternately, so that the installation cost and the maintenance cost are saved by reasonable arrangement. Further, the light source moving unit and the collecting moving unit 230 may be independently disposed or combined, wherein the independent disposition can more flexibly realize the illumination function and the monitoring function, and the combined disposition can further save the cost.

According to a preferred embodiment, a plurality of phosphor-coated light emitting panels may be disposed at a portion of the growth area, for example, a light reflecting panel that creates a dark environment for the plant roots is disposed above the plant roots in the growth area where the plants are cultivated, so that the phosphor-coated light reflecting side can be disposed toward the illumination portion 100. In the process that the illumination unit 120 of the illumination part 100 irradiates the plant light-receiving surface, part of light can irradiate the light-reflecting side of the light-reflecting plate positioned at the root of the plant through the gaps of the plant leaves, and the fluorescent powder on the light-reflecting side emits light with the wavelength required by the plant backlight surface based on the excitation of the transmitted light, so that the plant backlight surface can acquire certain illumination to supplement the light intensity acquired by the plant leaves, thereby reducing the energy consumption.

Preferably, since the growth area has an alternation of illumination period and shadow period, the light may not be received at some time by the movable or fixed collecting part 200, and thus the storage battery 332 formed by connecting several storage battery cells in series and/or parallel may be disposed in the monitoring body, so that the surplus electric energy converted by the photoelectric conversion element 331 is stored by the storage battery 332, so that the stored electric energy can be released by the storage battery 332 to ensure the normal operation of the collecting probe unit 220 when the energy consumption of the collecting probe unit 220 cannot be satisfied. Further, a plurality of reflective members may be regularly disposed in the growth area, so that a portion of the light emitted from the illumination unit 120 to the growth area can be reflected, and thus, the animal or plant located in the growth area can also receive light through the illumination of the reflected light at a backlight portion where the animal or plant cannot directly receive the illumination, and at the same time, the reflective members at a portion of the light can emit the reflected light to the photoelectric conversion element 331 in a manner of passing through the light-transmitting plate 113 of the illumination portion 100, so as to ensure that the photoelectric conversion element 331 can receive appropriate light to complete photoelectric conversion. The central control unit 310 can make an operation plan and a path of the collecting unit 200 based on factors such as an illumination plan of each illumination unit 100 and/or a residual electric quantity in the storage battery 332, for example, when the collecting unit 200 is in a non-monitoring state, the central control unit 310 can drive the collecting moving unit 230 through the collecting adjusting and controlling unit 250 to drive the monitoring main body to move to a corresponding position of the illumination unit 100 with high illumination intensity, long illumination time and wide illumination wavelength range, so as to store more electric energy for the storage battery 332 in the non-monitoring state; when the collection unit 200 is in the monitoring state, the central control unit 310 can reasonably plan the monitoring path of the collection unit 200 based on the illumination plan and the current state of each illumination unit 100, and the collection mobile unit 230 responds to the control signal to realize the collection of the growth state in a manner matched with each illumination unit 100.

According to a preferred embodiment, the central control unit 310 provided with the agricultural lighting device can number the divided growth areas and the corresponding illumination portions 100 to determine the types of animals and plants correspondingly provided in each growth area; determining standard environmental parameters corresponding to different growth areas based on different animal and plant types according to cloud data in a database, and correspondingly transmitting the standard illumination parameters to corresponding illumination parts 100 according to numbers, so that an illumination regulation and control unit 130 can respond to control signals to determine an appropriate light distribution scheme of the illumination unit, and accordingly light rays with corresponding parameters are emitted to the growth areas; judging the running state of the illumination part 100 based on the relation between the difference value between the real-time environmental parameter and the standard environmental parameter fed back by the sensing unit 320 and the set threshold value, and adjusting the illumination parameter of the illumination part 100 by driving the illumination regulating unit 130 when the difference value caused by the illumination factor exceeds the set threshold value; an operation plan and a path of the acquisition unit 200 are formulated based on factors such as the illumination plan of each illumination unit 100 and/or the residual electric quantity in the storage battery 332, and the acquisition control unit 250 is driven to drive the driving unit to operate according to a preset plan and path; the control signal is transmitted to the acquisition and control unit 250 to drive the acquisition probe unit 220 of the acquisition part 200 to acquire the growth state information of the animals and plants in each growth area, and information storage and analysis are performed in the acquisition main unit 210, so that the central control unit 310 can receive the current growth state of the corresponding detected animals and plants sent by the acquisition and control unit 250; the light collecting unit can be driven to collect the light excited by the fluorescent powder on the reflecting plate for the growing area for cultivating the plants so as to calculate the current growing state and growing stage of the plants by the light quantity passing through the gaps of the blades, and the current growing state of the plants can be sent to the central control unit 310 for correction; based on the collected information in the current growth state of the animals and plants and the historical growth database, the method compares the current growth state of the animals and plants with the information in the historical growth database to judge whether the growth environment of the animals and plants meets the preset condition, and when the difference between the current growth state and the historical data information exceeds the set threshold value, the illumination regulating unit 130 is driven to regulate the illumination parameters of the illumination part 100.
