Description

Technical Field

[0001] The present invention relates to the field of facility agriculture, and in particular to a method, supporting equipment and system for supplementing plant lighting. Background Art

[0002] In facility agriculture, plants usually need additional supplementary lighting in addition to natural light. The plant supplementary lighting technology involved is a modern agricultural technology that uses artificial light sources to compensate for the lack of light received by plants under natural light conditions.

[0003] Existing plant lighting methods and equipment typically utilize continuous fill-light fixtures. Continuing to use fill-light even after the plants have reached saturation can result in a certain degree of resource waste. Furthermore, the fill-light's effectiveness on plants varies due to the varying distances between the fill-light fixture and the plants being lit. When plants closer to the fixture reach saturation, plants farther away have yet to reach saturation, resulting in insufficient light resources. Existing fill-light technologies mostly utilize light with a fixed light-quality ratio, making them unsuitable for different plant types.

[0004] However, in the process of implementing the technical solutions of the embodiments of the present application, the inventors of the present application discovered that the above technology has at least the following technical problems:

[0005] 1. Existing technologies often measure illumination data based on fill light fixtures, ignoring the loss of light from the fill light fixtures to the crops to be filled. As a result, the calculated data also has corresponding errors.

[0006] 2. Existing plant supplementary lighting technologies often enhance crop photosynthesis and accumulation by adjusting supplementary lighting fixtures, which places high demands on the performance of supplementary lighting fixtures. When the performance of the lighting fixtures is limited or the parameters cannot be adjusted, it is difficult to meet the lighting needs of plant photosynthesis;

[0007] 3. Existing lighting technologies often mechanically apply uniform lighting to plants, lacking targeted lighting calculation and control, making it difficult to achieve efficient crop cultivation and production; Summary of the Invention

[0008] The embodiments of the present application aim to solve the problems of insufficient supplementary lighting, energy waste, high performance requirements for supplementary lighting equipment, and lack of targeted control in the prior art caused by optical path loss by providing a method, device, and supporting system for supplementary lighting for plants. By accurately monitoring the actual light received by plants and performing dynamic supplementary lighting based on their needs, efficient and accurate supplementary lighting for plants can be achieved, energy utilization can be improved, and dependence on specific high-performance supplementary lighting equipment can be reduced, thereby promoting plant photosynthesis and nutrient accumulation.

[0009] First, the present application provides a method for supplementing light to plants, comprising the following steps:

[0010] S1: Receive setting data, the console receives the standard data set by the administrator

[0011] DLI value and light threshold conditions for turning on fill lighting;

[0012] S2: Detect natural light. The console controls the light sensor to continuously detect the PPFD value at the plant to be supplemented with light under natural light.

[0013] S3: Monitor and compare the light intensity. The console continuously retrieves the PPFD value of the plant to be supplemented with light under natural light and compares it with the light threshold condition for starting the supplementary light. When the PPFD value of the plant to be supplemented with light under natural light is lower than the light threshold condition for starting the supplementary light, the supplementary light is turned on.

[0014] S4: Calculate the DLI for the day. The console retrieves the PPFD value at the plant to be supplemented with light during all natural light conditions on the day, and integrates the PPFD value at the plant to be supplemented with light during natural light conditions to obtain the DLI value for the day.

[0015] S5: Calculate the DLI difference. The console compares the DLI value of the day with the standard DLI value. When the DLI value of the day is lower than the standard DLI value, the console calculates the difference between the DLI value of the day and the standard DLI value to obtain the DLI difference.

[0016] S6: Detect fill light. The console controls the light sensor to continuously detect the PPFD value at the plant to be filled with light when the fill light is turned on.

[0017] S7: Calculating the target fill light duration. The console generates a target fill light duration value. The target fill light duration is calculated by the console based on the DLI difference divided by the PPFD value at the plant to be filled with light when the fill light is turned on. Specifically, the target fill light duration is calculated by dividing the DLI difference by the PPFD value at the plant to be filled with light when the fill light is turned on.

[0018] S8: Control the fill light fixture. The console controls the on and off status of the fill light according to the target fill light duration. When the plant light is on for the target fill light duration,

[0019] The console controls the fill light to turn off;

[0020] Furthermore, in the step of accepting the setting data, the console also accepts the local sunrise time set by the administrator. In the step of controlling the fill light, if the time reaches the local sunrise time, even if it is not the time for the console to control the fill light to be turned off, the console still controls the fill light to be turned off. That is, the sunrise time setting has a higher priority than the plant fill light duration setting;

[0021] By combining the setting of sunrise time and the setting of fill light duration, the on and off status of plant fill light can be controlled. When there is sufficient light after sunrise or when the fill light is sufficient, the plant fill light can be turned off, avoiding the waste of excess fill light and the inability of plants to utilize light energy. On the other hand, it also enables the plant to be filled with light for a specific duration according to the needs of the plant to meet the growth needs of the plant.

[0022] Furthermore, in the steps of detecting natural light and detecting supplemental light, the light sensor detects around the growth area of ​​the plant to be supplemented with light when the plant is exposed to natural light and when the supplemental light is on.

[0023] By detecting the light data from the plants to be supplemented with light, the error of the detected data is optimized, the real light parameters of the plants are known, and the loss of light in the process from the supplementary light to the plants to be supplemented with light is avoided. This solves the energy waste caused by light leakage in the light path in the existing technology, improves the energy utilization rate, and understands the specific light parameters of the plants, which can better guide the plant supplementary lighting operation, thereby promoting the plants to increase the photosynthesis rate and accelerate plant growth.

[0024] Furthermore, the number of the light sensors can be set arbitrarily according to the situation. When the number of light sensors is ≥1, the average value of the detection values ​​of each light sensor is taken to generate the PPFD value at the plant to be supplemented with light under natural light and the PPFD value at the plant to be supplemented with light when the supplement light is turned on;

[0025] By arranging a plurality of light sensors (1) around the plant to be supplemented with light, it is possible to avoid the influence of the error of a single light sensor on the PPFD value at the plant to be supplemented with light, thereby preventing the supplementary light operation from being affected. This improves the detection accuracy of the actual light parameters of the plant to be supplemented with light, and can better guide the supplementary light operation of the plant, thereby promoting the plant to increase the photosynthesis rate and accelerating the plant growth.

[0026] Furthermore, the data and operation records generated corresponding to each step in the plant light supplementation method are recorded so that the administrator can call the data and check the light supplementation equipment;

[0027] In addition, the present application also provides a device set for supplementing light for plants, which is applicable to any of the above-mentioned methods for supplementing light for plants, including:

[0028] A light sensor, the light sensor is used to continuously detect the natural light PPFD and the supplementary light PPFD at the plant;

[0029] Plant fill-in light, which is used to provide supplementary light to the plants to be filled when natural light is insufficient;

[0030] The console is used to receive data from the light sensor and data input by the administrator, and process and output the received data. Specifically, it includes:

[0031] Interaction desk, used to exchange information and data with administrators;

[0032] Microcomputer, used to process various data and obtain results;

[0033] The communication device is used to receive information and data detected by the light sensor, and send a control signal to the plant light according to the calculation result of the microcomputer to control the operation of the plant light;

[0034] Timing device, used to set and manage the on-time of the plant fill light;

[0035] Furthermore, the console also includes a log hard disk for recording various operations of the equipment set and various data obtained and generated, so as to facilitate manual review or call of data, as well as inspection of the fill light equipment, and strengthen manual management and control of the fill light equipment;

[0036] Furthermore, the light sensors are all arranged around the growth area of ​​the plants to be supplemented with light, and the light parameters are measured from the plants to be supplemented with light, thereby ensuring the accuracy of the detection results and avoiding the situation where light leakage during the illumination process affects the final detection data. This achieves a more accurate measurement of the light parameters of the plants to be supplemented with light, and the obtained accurate data can more accurately guide the supplementary lighting operation.

[0037] Furthermore, the number of the light sensors can be set arbitrarily. When the number of light sensors is ≥1, when generating the PPFD value at the plant to be supplemented with light under natural light and the PPFD value at the plant to be supplemented with light when the supplementary light is on, the data detected by each light sensor is averaged, and the results are used as their respective actual values ​​and sent to the console for data processing;

[0038] In addition, the present application also provides a control system for a device set for supplementary lighting of plants. By using any of the above-mentioned device sets for supplementary lighting of plants, combined with any of the above-mentioned methods for supplementary lighting of plants, sufficient supplementary lighting for plants is achieved, specifically including:

[0039] Fill-in lighting module, used to provide fill-in lighting for plants to be filled with light;

[0040] The information input module obtains the following data from the management personnel: first data and second data, where the first data is the standard DLI value and the second data is the light threshold condition for starting the fill light:

[0041] The sensing detection module continuously detects the ambient light and obtains third data and sixth data, wherein the third data is the PPFD value at the plant to be supplemented with light when the ambient light is natural, and the sixth data is the PPFD value at the plant to be supplemented with light when the supplement light is on;

[0042] The data processing module calls the data from the information input module and the data from the sensor detection module to generate operation control data, specifically:

[0043] The second data and the third data are called and compared. When the value of the second data is higher than the third data, the first operation control data is generated. The operation control data is:

[0044] Turn on the fill light to illuminate the target;

[0045] Retrieving all third data of the day and integrating the third data to obtain fourth data, where the fourth data is the DLI of the day;

[0046] Calling the first data and the fourth data, when the value of the first data is higher than the value of the fourth data, calculating the difference between the first data and the fourth data to obtain the fifth data, wherein the fifth data is the DLI gap value of the plant to be supplemented with light on that day;

[0047] Calling the fifth data and the sixth data, dividing the fifth data by the sixth data, and calculating the seventh data, wherein the seventh data is the target fill light duration of the fill light illumination module;

[0048] a timing module, recording eighth data, wherein the eighth data is the working time of the fill light illumination module;

[0049] The operation control module controls the fill light module to perform fill light according to the data generated by the operation control module, specifically:

[0050] When the operation control data is received, the fill light module is controlled to turn on the fill light to fill light the plants to be filled light;

[0051] When the seventh data is received, the timing module is controlled to be turned on to record the eighth data, and when the eighth data increases to reach the value of the seventh data, the fill light module is controlled to be turned off;

[0052] The information feedback module generates record information data and feeds the record information data back to the administrator. The record information data is the sum of the actual information and control information obtained by each detection module.

[0053] It is characterized by further comprising a storage module for recording control data and detection information, for recording and saving recorded information, so as to facilitate manual control or inspection of the entire set of equipment and method processes, and avoid malfunctions or erroneous fill light;

[0054] Furthermore, the number of the sensor detection modules can be set arbitrarily, and they are set within the range around the plants to be supplemented with light to ensure the accuracy of the monitoring data. By setting any number of sensor detection modules around the plants to be supplemented with light to detect the supplementary light environment around the plants, the measurement error of the actual supplementary light parameters in the existing technology is reduced, and the accuracy and precision of the measurement data are improved, so that the final detection results can more accurately guide the supplementary light operation to be carried out more accurately.

[0055] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0056] 1. Since the light parameters are detected from the plants to be supplemented, it effectively solves the technical problems of insufficient or overflowing supplemented light caused by light leakage or data errors when supplementing light to plants according to the parameters of the supplemented light equipment in the existing technology, thereby achieving more accurate supplemented light for plants;

[0057] 2. Since the fill light time is calculated based on the light parameters detected at the plant to be filled light, it can adapt to a wider range of fill light equipment and fill light the plants according to their lighting capabilities. This effectively solves the technical problem of existing plant fill light technology that often has high requirements on the performance of fill light equipment, thereby achieving adaptation to a wider range of fill light equipment.

[0058] 3. Since the duration of the fill light in this application is calculated based on the light requirements of the plant itself and the specific light data obtained by the plant, it effectively solves the two problems of the existing technology in which large-scale unified fill light for plants often cannot accurately meet the needs of the plants or over-fill light for the plants. It achieves the most accurate fill light operation for the plants within the capabilities of the fill light equipment; BRIEF DESCRIPTION OF THE DRAWINGS

[0071] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0072] Example 1

[0073] like Figure 1 As shown, a method for supplementing light to plants in this embodiment includes the following steps:

[0074] S1: Receive setting data, console 3 receives the standard data set by the administrator

[0075] DLI value and light threshold conditions for turning on fill lighting;

[0076] S2: Detecting natural light, the control console 3 controls the light sensor 1 to continuously detect the PPFD value at the plant to be supplemented with light under natural light;

[0077] S3: Monitoring and comparing light. The control console 3 continuously retrieves the PPFD value of the plant to be supplemented with light under natural light and compares it with the light threshold condition for turning on the supplementary light. When the PPFD value of the plant to be supplemented with light under natural light is lower than the light threshold condition for turning on the supplementary light, the supplementary light is turned on.

[0078] S4: Calculate the DLI for the day. The control console 3 retrieves the PPFD values ​​of the plants to be supplemented with light during all natural light conditions on the day, and integrates the PPFD values ​​of the plants to be supplemented with light during natural light conditions to obtain the DLI value for the day.

[0079] S5: Calculate the DLI difference. The console 3 compares the DLI value of the day with the standard DLI value. When the DLI value of the day is lower than the standard DLI value, the console 3 calculates the difference between the DLI value of the day and the standard DLI value to obtain the DLI difference.

[0080] S6: Detecting the fill light, the light sensor 1 of the control console 3 continuously detects the PPFD value at the plant to be filled with light when the fill light is turned on;

[0081] S7: Calculating the target fill light duration. The console 3 generates a target fill light duration value. The target fill light duration is calculated by the console 3 based on the DLI difference divided by the PPFD value at the plant to be filled with light when the fill light is turned on. Specifically, the target fill light duration is calculated by dividing the DLI difference by the PPFD value at the plant to be filled with light when the fill light is turned on.

[0082] S8: Control the fill light fixture. The console 3 controls the on and off state of the fill light according to the target fill light duration. When the plant light is on for a duration that reaches the target fill light duration,

[0083] Console 3 controls the fill light to turn off;

[0084] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0085] The technical solution of this embodiment is as follows: the PPFD values ​​at the plant are detected during natural light exposure and when the fill light device is used for supplementary lighting, and all the PPFD values ​​at the plant during natural light exposure are integrated to obtain the plant DLI for the day. This actual DLI is compared with the standard DLA value input by the administrator to obtain the difference, and the above difference is then divided by the PPFD value when the fill light device is used for supplementary lighting to obtain the supplementary lighting duration of the supplementary lighting device. The plant fill light 2 is then controlled to provide supplementary lighting to the plant to be supplemented, thereby meeting the plant's lighting needs.

[0086] According to the impact of the supplementary lighting equipment on the plants, the amount of light received by the plants, and the lighting standards of the plants, accurate supplementary lighting is performed on the plants to be supplemented. This solves the technical problem of the existing technology of mechanically and uniformly supplementing the plants and lacking targeted supplementary lighting calculation and control. It achieves the most accurate supplementary lighting within the capabilities of the supplementary lighting equipment, promotes plant photosynthesis, and realizes efficient plant cultivation and production.

[0087] In addition, this embodiment can also solve the technical problem in the existing technology that it is often necessary to use a high-performance or relatively functional fill light for fill lighting, and the demand for fill lighting equipment is high. This embodiment adaptively adjusts the working time of the fill light equipment through the impact of the fill light equipment on the plants when it is working to meet the lighting needs of the plants to be filled light, and achieves the technical effect of using a plant fill light 2 of any performance to fill light the plants, thereby promoting plant growth.

[0088] Example 2

[0089] This embodiment is based on the technical features of the first embodiment, which form a complete technical solution. In the step of accepting the setting data, the console 3 also accepts the setting from the administrator, or retrieves the local sunrise time through the network, and in the step of controlling the fill light, if the time reaches the local sunrise time, even if the console 3 does not control the fill light to be turned off, the console 3 still controls the fill light to be turned off, that is, the sunrise time setting has a higher priority than the plant fill light duration setting;

[0090] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0091] This embodiment adds a local sunrise time to the fill light method, and controls the fill light to turn off when the sunrise time is reached, thereby avoiding energy waste caused by continuing to turn on the fill light device when there is sufficient light, and achieving more efficient utilization of energy such as electricity and light, so that more energy can be absorbed by plants and converted into nutrients.

[0092] Example 3

[0093] This embodiment is based on the technical features of the first embodiment, which form a complete technical solution. In the steps of detecting natural light and detecting supplemental light, the light sensor 1 detects the PPFD value at the plant to be supplemented when the natural light is on and the PPFD value at the plant to be supplemented when the supplemental light is on, both from the area around the plant to be supplemented.

[0094] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0095] This embodiment can solve the problems in the existing technology. By detecting the lighting data from the plants to be supplemented with light, the error of the detected data is optimized, and the real light parameters of the plants are known. This avoids the loss of light from the supplementary light lamp to the plants to be supplemented with light in the existing supplementary light technology. When supplementing light, only the parameters of the supplementary light equipment are considered, while the technical problem of light dispersion and loss in the optical path is ignored. The lighting data at the plants are used to calculate the supplementary light parameters and perform the supplementary light settings, thereby achieving a technical effect of more efficient supplementary light for the plants.

[0096] Example 4

[0097] like Figure 2 As shown, in this embodiment, on the basis of the various technical features of the first embodiment forming a complete technical solution, the number of the light sensors 1 can be arbitrarily set according to the situation. When the number of the light sensors 1 is ≥ 1, the average value of the detection values ​​of the light sensors 1 is taken to generate the PPFD value at the plant to be supplemented with light under natural light and the PPFD value at the plant to be supplemented with light when the supplement light is on.

[0098] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0099] This embodiment sets up multiple light sensors 1 and calculates the average of the monitoring data of multiple sensors, thereby avoiding the situation where a single light sensor 1 fails or the detection accuracy is insufficient, and the result of calculating the filling time of the filling light equipment causes a large error. This also avoids the high-error filling light operation, and improves the detection accuracy of the actual light parameters of the plants to be filled with light. It can better guide the implementation of the plant filling light operation, thereby promoting the plants to increase the photosynthesis rate and accelerate plant growth.

[0100] Example 5

[0103] Plant fill light 2, which is used to provide supplementary light to the plants to be supplemented when natural light is insufficient;

[0104] The console 3 is used to receive data from the light sensor 1 and data input by the administrator, and process and output the received data, specifically including:

[0105] Interaction station 31, used to exchange information and data with the administrator;

[0106] A microcomputer 32 is used to process various data and obtain results;

[0107] The communication device 33 is used to receive information and data detected by the light sensor 1 and send a control signal to the plant light 2 according to the calculation result of the microcomputer 32 to control the operation of the plant light 2;

[0108] The timing device 34 is used to set and manage the on-time of the plant fill light 2;

[0109] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0110] This embodiment provides a device set for supplementary lighting for plants, uses a light sensor 1 to detect the lighting parameters at the plants to be supplemented, and after obtaining the actual lighting parameters at the plants to be supplemented, combines the data entered by the administrator in the console 3 to calculate and generate the supplementary lighting duration of the plant supplementary light 2, and controls the operation of the supplementary lighting device. This solves the technical problem in the prior art that it is difficult to meet the lighting requirements of plant photosynthesis when the performance of the lamp is limited or the parameters cannot be adjusted, and achieves the technical effect of using any performance supplementary lighting device to supplement the plants within the capability range.

[0111] Example 6

[0112] In this embodiment, based on the technical features of the fifth embodiment forming a complete technical solution, the console 3 further includes a log hard disk for recording various operations of the equipment set and various data obtained and generated, so as to facilitate manual review or call of data and inspection of the fill light device, thereby strengthening manual management and control of the fill light device;

[0113] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0114] This embodiment adds a log hard disk to record in detail the various operations of the equipment package and the various data obtained and generated, thereby avoiding data loss and allowing administrators to manually review the data, which can assist in the collection of plant growth light data and enhance the manual management capabilities of the equipment package and the efficiency of data utilization.

[0115] Example 7

[0116] This embodiment is based on the technical features of the fifth embodiment, which form a complete technical solution. The light sensors 1 are all arranged around the growing area of ​​the plants to be supplemented with light, and measure the light parameters from the plants to be supplemented with light.

[0117] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0118] This embodiment ensures the accuracy of the detection results by detecting the lighting parameters from the plants to be supplemented with light, avoids the situation where light leakage during the lighting process affects the final detection data, and achieves more accurate measurement of the light parameters of the plants to be supplemented with light. The obtained accurate data can more accurately guide the supplementary lighting operation.

[0119] Example 8

[0120] like Figure 4 As shown, this embodiment is based on the various technical features of the fifth embodiment forming a complete technical solution, wherein the number of the light sensors 1 can be set arbitrarily. When the number of the light sensors 1 is ≥ 1, when generating the PPFD value at the plant to be supplemented with light under natural light and the PPFD value at the plant to be supplemented with light when the supplement light is turned on, the data detected by each light sensor 1 are averaged, and the results are used as their respective actual values, which are sent to the console 3 for data processing;

[0121] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0122] This embodiment improves the accuracy of measuring light parameters at the plant by flexibly setting the number of light sensors 1, avoids high-error fill light, and achieves improved detection accuracy of the actual light parameters of the plant to be fill light, which can better guide the plant fill light operation, thereby promoting the plant to increase the photosynthesis rate and accelerate plant growth.

[0127] The sensing detection module continuously detects the ambient light and obtains third data and sixth data, wherein the third data is the PPFD value at the plant to be supplemented with light when the ambient light is natural, and the sixth data is the PPFD value at the plant to be supplemented with light when the supplement light is on;

[0128] The data processing module calls the data from the information input module and the data from the sensor detection module to generate operation control data, specifically:

[0129] The second data and the third data are called and compared. When the value of the second data is higher than the third data, the first operation control data is generated. The operation control data is:

[0130] Turn on the fill light to illuminate the target;

[0131] Retrieving all third data of the day and integrating the third data to obtain fourth data, where the fourth data is the DLI of the day;

[0132] Calling the first data and the fourth data, when the value of the first data is higher than the value of the fourth data, calculating the difference between the first data and the fourth data to obtain the fifth data, wherein the fifth data is the DLI gap value of the plant to be supplemented with light on that day;
