Abstract
Description
Technical Field
[0001] This invention relates to the field of plant supplemental lighting, and more particularly to a supplemental lighting lamp and control system for plant factories. Background Technology
[0002] Supplemental lighting technology for plants is a crucial innovation in modern agriculture. It uses artificial light sources to supplement or replace natural light, meeting the light requirements for plant growth. In situations with insufficient natural light, such as winter, cloudy days, or indoor growing environments, supplemental lighting effectively promotes photosynthesis, thereby increasing crop yield and quality. Furthermore, this technology helps extend the growing season, enabling crop production during seasons difficult to achieve with traditional agriculture, which is significant for improving the sustainability of agricultural production. LED light sources are widely used in plant supplemental lighting due to their advantages such as high luminous efficiency, low heat generation, small size, and long lifespan. Compared to traditional high-pressure sodium lamps or fluorescent lamps, LED light sources not only have a longer lifespan and an energy efficiency ratio more than twice that of traditional lamps, but also provide a more precise and controllable spectral distribution, meeting the specific wavelength light requirements of different plant species. For example, blue and red light are the light waves most sensitive to plant growth; LED light sources can adjust the ratio of these two light sources to optimize the efficiency of plant photosynthesis. In addition, LED plant lighting equipment is energy-saving and environmentally friendly, significantly reducing electricity consumption and operating costs.
[0003] With the continuous advancement of LED technology, the intelligent adjustment systems of plant supplemental lighting are also constantly being improved. These intelligent systems can automatically adjust parameters such as light intensity, photoperiod, and light quality according to the plant's growth stage and needs, providing a more optimized growth environment for the plant. For example, by precisely controlling the photoperiod, changes in natural sunlight can be simulated, promoting flowering and fruiting. The introduction of intelligent adjustment systems not only improves the efficiency of plant supplemental lighting but also brings greater flexibility and controllability to agricultural production. Overall, the development of plant supplemental lighting technology, especially in the application of LED plant lighting equipment and the research of intelligent adjustment systems, provides strong support for modern agricultural production. The application of these technologies not only improves crop yield and quality but also helps to realize the automation and intelligence of agricultural production, promoting the progress of agricultural science and technology and the sustainable development of the agricultural industry.
[0004] Existing plant supplemental lighting equipment, regardless of size, will have a heat dissipation problem if the supplemental lighting bulbs are designed to be tightly packed, making it difficult to dissipate the heat generated by the bulbs in a timely manner.

If they are changed to soil cultivation, it is difficult to accurately control the amount of irrigation. Small supplemental lighting equipment simply does not consider the design of irrigation function.

[0063] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:
[0064] 1. Due to the adoption of a three-layer lamp plate design with a first layer, a second layer, and a third layer, the liquid can flow in the cavity formed by the three layers. Therefore, the technical problem of heat dissipation in existing supplementary lighting fixtures is effectively solved, thereby achieving the technical effect of heat dissipation for supplementary lighting fixtures.
[0065] This system can save water resources. Taking traditional flood irrigation as an example, each hectare consumes 1,200-2,000 cubic meters of water per year. If this system adopts small-dose irrigation, it can be approximated as spot irrigation or drip irrigation, saving 60%-70% of water resources compared to traditional flood irrigation. If large-dose irrigation is adopted, it can be approximated as sprinkler irrigation, saving 40% of water resources compared to traditional flood irrigation.
[0066] Secondly, this system absorbs heat through the liquid and utilizes the heated liquid to regulate the temperature of the irrigation liquid, thus recovering some of the electrical resources converted into heat energy. 80% of the electrical energy of an LED is converted into light energy, and the remaining 20% into internal energy. The liquid flowing within this system covers approximately 60% of the LED's surface, and depending on the liquid's flow rate and temperature, it can absorb 70%-95% of the heat generated, which can then be used to regulate the temperature of the irrigation liquid.
[0067] Secondly, this system cools the lamp panel by using flowing liquid. Compared to the operating temperature of LED lamp groups without cooling devices, theoretically, the operating temperature of the lamp group can be controlled at 55%-80% of the operating temperature of LED lamp groups without cooling devices. Factors causing fluctuations include the type of liquid (specific heat capacity), flow rate, flow volume, density of lamp beads, and power of lamp beads.
[0068] 2. Due to the adoption of a three-layer lamp panel design (first, second, and third layers), as well as a watering nozzle and control system, the technical problem of watering that existing small supplemental lighting equipment cannot solve is effectively solved, thus achieving the technical effect of watering while supplementing lighting.
[0069] The control system can control the liquid flow rate, volume, and temperature inside the lamp panel, as well as the liquid entering the container and being mixed to the required liquid conditions before watering operations, including but not limited to: water cooling followed by water ...
[0070] In addition, users can interact with the control system to set control conditions and achieve self-regulation.
[0071] In addition, the control system can interact with a cloud database, automatically obtaining the necessary control conditions data by selecting the corresponding crop type. Attached Figure Description

[0094] This application provides a supplemental light for plant factories and its control system, which solves the technical problems that existing supplemental light bulbs are difficult to dissipate heat when densely arranged, affecting the operation of the bulbs, and that existing small supplemental lighting devices do not have watering capabilities.
[0095] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:
[0096] To address the heat dissipation issues of existing supplementary lighting fixtures, a three-layer lamp panel design is proposed. The lamp panel consists of a first layer, a second layer, and a third layer, with cavities between each layer. Liquid can enter these cavities through pipes and flow out through a pouring port, achieving a liquid-cooling-like effect. The flowing liquid carries away heat to dissipate heat from the supplementary lighting. A flow control device can be installed at the connection between the pipes and the lamp panel to control the liquid flow rate and thus the heat dissipation efficiency. Furthermore, different heat dissipation methods can be implemented by changing the type and temperature of the liquid.
[0097] To address the technical problem of existing small supplemental lighting fixtures being unable to perform irrigation operations, a three-layer lamp plate design is employed. Liquid flows through an internal cavity and exits through the irrigation port into an outdoor storage tank. After being mixed, it is then used for irrigation according to the crop's needs. The liquid can be water, nutrient solution, or other liquids as required, providing options for different user needs. A typical method involves using water as a cooling liquid, flowing through the first cavity formed by the first and second layers into the container of the liquid regulating device, where it mixes with external water to adjust the temperature; or using water as a cooling liquid, mixing it with external nutrient solution in the container to achieve the required temperature and concentration for irrigation; or other mixing operations according to user needs. Simultaneously, the control system's flow control and position control devices can be used in conjunction to control the liquid flow rate, inflow volume, or cavity volume to alter irrigation efficiency. Specifically, the position control device adjusts the size of the first cavity between the first and second layers, and the flow control device controls the amount and flow rate of liquid within the first cavity. Similarly, by adjusting the size of the second cavity between the second and third layers using a position control device, the flow rate of the liquid in the second cavity can be controlled.
[0098] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0099] Example 1
[0100] like Figure 1-16The illustrated grow light for a plant factory includes a light panel 1 and a power cord 2. The light panel 1 has a three-layer design: a first layer 103, a second layer 104, and a third layer 105. The first layer 103 is made of insulating material, with a cylindrical protrusion on one side and an interface 101 at the center of the other side for housing electrical wires. The second layer 104 has an opening corresponding to the protrusion of the first layer 103, allowing the protrusion to pass through, forming a cavity between the two layers. The third layer 105 also has an opening corresponding to the protrusion of the first layer 103, allowing the protrusion to pass through, forming a cavity between the second and third layers. Sealing elements are provided at the connections between the protrusion of the first layer 103 and the corresponding openings of the second and third layers 104 and 105 to prevent liquid leakage. The surfaces of the cavities formed by the first layer plate 103, the second layer plate 104, and the third layer plate 105 are all coated with a waterproof and corrosion-resistant coating. A pipe 102 connects to the cavities formed inside the first layer plate 103 and the second layer plate 104 at the side of the lamp plate 1, allowing liquid to enter through the pipe 102. Another channel pipe at the diagonal connects the cavities formed by the first layer plate 103 and the second layer plate 104 with the cavities formed by the second layer plate 104 and the third layer plate 105. The third layer plate 105 is also provided with several pouring heads 302, which are double-layered cylindrical shell-shaped protrusions. The second cylindrical shell and the first cylindrical shell form rounded corners, and the overall shape is like a drip nozzle with an opening at the top for internal liquid to flow out. Several cylindrical ends from the protrusions of the first layer plate 103 are arranged around the pouring heads 302, with LED beads 301 at their ends. The pouring heads 302 and the surrounding LED beads 301 form a lamp unit 3. Several lamp units 3 are distributed on the lamp plate 1. In use, the interface 101 on the back of the lamp panel 1 can be directly connected to the power supply. Considering the device compatibility of this application example, it can also be connected to the power supply via the power cord 2. The power cord 2 includes an adapter 203, which can be connected to the interface 101 on the back of the lamp panel 1. An electric wire 202 extends from the tail of the adapter 203. The length of the electric wire 202 is not limited, and a plug 201 is provided at the tail for connecting to the power supply. External liquid flows into the cavity formed by the first layer plate 103 and the second layer plate 104 through the pipe 102, and then flows into the cavity formed by the second layer plate 104 and the third layer plate 105 through another channel, finally flowing out from the pouring head 302.
[0101] Specifically, a control system 4 is provided around the lamp panel 1. The control system 4 is divided into a processor 401, a position control device 402, and a flow control device 403.
[0102] The controller 401 is disposed on one side of the lamp panel 1, and includes:
[0103] The information processing module 4011 is used to process the information received by the information receiving module 4013 and generate corresponding instruction information to be issued to the corresponding module and device, as well as generate feedback information;
[0104] The information sending module 4012 is used to send the feedback information generated by the information processing module 4011 to the outside world;
[0105] The information receiving module 4013 is used to receive information from the outside world and transmit it to the information processing module;
[0106] The lighting control module 4014 is used to receive corresponding instruction information from the information processing module 4011 and drive the corresponding device to work.
[0107] The motor drive module 4015 is used to receive corresponding instruction information from the information processing module 4011 and drive the corresponding device to work.
[0108] The valve control module 4016 is used to receive corresponding instruction information from the information processing module 4011 and drive the corresponding device to work.
[0109] Temperature monitoring module 4017 is used to acquire temperature information of the liquid inside the liquid regulating device and transmit it to the information processing module;
[0110] The flow control module 4018 is used to acquire information on the amount of liquid flowing through the module and transmit it to the information processing module.
[0111] The power supply module 4019 is used to supply power to the information processing module 4011, the information sending module 4012, the information receiving module 4013, the lighting control module 4014, the motor drive module 4015, the valve control module 4016, the temperature monitoring module 4017, and the flow control module 4018.
[0112] The position control devices 402 are a pair, arranged in parallel on the adjacent two sides of the side of the lamp panel 1 where the processor 401 is located. The main body is a rectangular strip, and the length is close to the side length of the lamp panel 1.
[0113] The first limiting member 4021 is a cuboid with one long side coupled to the first layer plate 103. A first channel 4026a, which is a cylindrical cavity, is provided on the vertical line of the center of the long side. The first motor 4025a is disposed inside a cuboid, which is positioned corresponding to the first channel 4026a, but is wider than the first channel 4026a and is embedded in the first limiting member 4021. The second limiting member 4022 is mainly a cuboid, forming the first cavity with the first limiting member 4021. The stud 4024 is mainly a cylinder, which passes through the second limiting member 4022, with two cylindrical sections of equal length exposed at both ends. Its size corresponds to the first channel 4023 and is smaller than its volume. It is threaded. The third limiting member 4023 is a cuboid, forming a second cavity with the second limiting member 4022. The second channel 4026b has the same specifications as the first channel 4026a and is provided with another stud 4024 corresponding to the second limiting member 4022. The second motor 4025b is provided inside a cuboid, which is provided with the second channel 4026b, but is wider than the second channel 4026b and is embedded in the third limiting member 4023.
[0114] During operation, motors 4025a and 4025b receive commands and rotate, pulling or pushing stud 4024 and the second connector 4022 toward the first restrictor 4021 via the threads on stud 4024. This causes the second layer plate 104 to move toward the first layer plate 103, thereby contracting or expanding the cavity formed by the two. The stud 4024 moves axially within the corresponding first channel 4026a.
[0115] Alternatively, the third limiting member 4023 can be pulled up or pushed away from the second limiting member 4022 via the thread on the stud 4024, so as to drive the third layer plate 105 to move towards the second layer plate 104, so as to shrink or enlarge the cavity formed by the two, and the stud 4024 moves axially inside the corresponding second channel 4026b.
[0116] In use, the user can interact with the control system 4 to change the size of the first cavity and the second cavity, thereby controlling the flow rate, velocity, and pressure of the liquid in the cavity, and thus indirectly controlling the temperature of the outflowing liquid and the lamp plate temperature.
[0117] The flow control device 403 is a valve, and the pipeline is connected to the cavity formed by the first plate 103 and the second plate 104 via the flow control device 403.
[0118] The liquid regulating device 404 is primarily a container 4041, which can be placed outdoors or in other suitable locations. It is connected to liquid regulating device pipes 4042a-c. One end of pipe 4042a connects to the container 4041, and the other end connects to the first cavity formed by the first and second layer plates 103 and 104. One end of pipe 4042b connects to the container 4041, and the other end connects to the second cavity formed by the second and third layer plates 104 and 105. One end of pipe 4042c connects to the container 4041, and the other end extends out, passing sequentially through a water valve 4045 and a flow meter 4044 to an external liquid source. A faucet 4043 is installed on the container 4041 to release the liquid inside or for other purposes. A stirrer 4046 is located at the center of the bottom of the container 4041, and a temperature sensor 4047 is installed on its surface.
[0119] In use, the user can interact with the plant factory grow light described in this application example through the control system 4 to adjust the light intensity of the grow light, the watering rate, and the temperature of the watering liquid.
[0120] For most crops, the ideal irrigation temperature is 18-25 degrees Celsius, while it is lower for leafy vegetables and higher for fruit vegetables, with a range of 1-3 degrees Celsius.
[0121] The liquid source for container 4041 is via liquid regulating device pipes 4042a and 4042c. Liquid entering through pipe 4042a is the liquid that has cooled the lamp plate 1 after flowing through the first and second plates 103 and 104. Pipe 4042c is an external liquid source, allowing for the manual injection of water, nutrient solution concentrate, or other concentrations of nutrient solution into container 4041. The liquid in container 4041 is directed to pipe 4042b and tap 4043. The prepared liquid can be used to irrigate crops via pipe 4042b or discharged through tap 4043 for other uses.
[0122] Typical methods for preparing liquids include:
[0123] Water is used as the cooling liquid. It enters the cavity formed between the first layer plate 103 and the second layer plate 104 through the pipe 102 on the lamp plate 1 to cool the lamp plate 1. After cooling, it flows into the container 4041 of the liquid regulating device 404 through the liquid regulating device pipe 4042a. At this time, if water is selected as the irrigation liquid, the temperature of the water in the container 4041 is obtained by the temperature sensor 4047. The required amount of external water is calculated, and then it flows into the container 4041 through the liquid regulating device pipe 4042b. After stirring, it is adjusted to the required temperature for irrigation. If nutrient solution is selected as the irrigation liquid, the amount of high-concentration nutrient solution to reach the required nutrient solution concentration is calculated based on the water flow rate recorded by the flow metering device of the flow control device 403, and then added and mixed for irrigation.
[0124] A low-concentration nutrient solution is used as a cooling liquid. It enters the cavity formed between the first layer plate 103 and the second layer plate 104 through the pipe 102 on the lamp plate 1 to cool the lamp plate 1. After cooling, it flows into the container 4041 of the liquid regulating device 404 through the liquid regulating device pipe 4042a. Based on the flow rate of the low-concentration nutrient solution recorded by the flow metering device of the flow control device 403, the amount of high-concentration nutrient solution to achieve the required nutrient solution concentration is calculated, added, and mixed for irrigation.
[0125] A high-concentration nutrient solution is used as a cooling liquid. It enters the cavity formed between the first layer plate 103 and the second layer plate 104 through the pipe 102 on the lamp plate 1 to cool the lamp plate 1. After cooling, it flows into the container 4041 of the liquid regulating device 404 through the liquid regulating device pipe 4042a. Based on the flow rate of the high-concentration nutrient solution recorded by the flow metering device of the flow control device 403, the amount of low-concentration nutrient solution or water required to achieve the desired nutrient solution concentration is calculated, added, and mixed for irrigation.
[0126] A nutrient solution of appropriate concentration is used directly as a cooling liquid, entering the cavity formed between the first layer plate 103 and the second layer plate 104 through the pipe 102 on the lamp plate 1. After cooling the lamp plate 1, the solution flows into the container 4041 of the liquid regulating device 404 through the liquid regulating device pipe 4042a. It can be stirred by the stirrer 4046 and cooled to the required temperature before being poured in.
[0127] The preferred application scenario is that the plant tray below is positioned at the unit 3 position corresponding to the example in this application. The liquid connected to the pipe 102 can be water or other liquids required for irrigation besides nutrient solution. The irrigation rate can be controlled by controlling the pressure of the cooling liquid source connected to the pipe 102, or by controlling the size of the internal cavity of the lamp panel 1 to increase the internal liquid pressure, thereby indirectly increasing the liquid flow rate.
[0128] By controlling the liquid flow rate, part of it can enhance the cooling effect of the lamp panel, and another part can be used to control the flow rate of the irrigation liquid and the amount of liquid poured per unit time.
[0129] Admittedly, distributing several LED beads 301 around a watering inlet 302 to form a light unit 3 is for the convenience of designing supplementary lighting coverage and efficiency. The LED beads 301 can also be arbitrarily placed on it. The double-layered design of the lamp plate 1 almost covers the entire interior of the lamp plate 1, so the LED beads 301 can enjoy the heat dissipation effect brought by the liquid no matter where they are placed on the lamp plate. At the same time, the evenly distributed watering heads 302 in the figure are also designed to facilitate the use with other plant trays on the market. In actual use, the distribution and position can be changed according to actual needs.
[0130] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:
[0131] 1. When the LED beads and the water supply work simultaneously, the LED beads can be cooled, allowing for a more compact LED bead distribution design.
[0132] 2. It can perform irrigation operations and control operations.
[0133] Example 2
[0134] Depend on Figure 1-6The illustrated grow light for a plant factory includes a light panel 1 and a power cord 2. The light panel 1 has a three-layer design: a first layer 103, a second layer 104, and a third layer 105. The first layer 103 is made of insulating material, with a cylindrical protrusion on one side and an interface 101 at the center of the other side for housing electrical wires. The second layer 104 has an opening corresponding to the protrusion of the first layer 103, allowing the protrusion to pass through, forming a cavity between the two layers. The third layer 105 also has an opening corresponding to the protrusion of the first layer 103, allowing the protrusion to pass through, forming a cavity between the second and third layers. Sealing elements are provided at the connections between the protrusion of the first layer 103 and the corresponding openings of the second and third layers 104 and 105 to prevent liquid leakage. The surfaces of the cavities formed by the first layer plate 103, the second layer plate 104, and the third layer plate 105 are all coated with a waterproof and corrosion-resistant coating. A pipe 102 connects to the cavities formed inside the first layer plate 103 and the second layer plate 104 at the side of the lamp plate 1, allowing liquid to enter through the pipe 102. Another channel pipe at the diagonal connects the cavities formed by the first layer plate 103 and the second layer plate 104 with the cavities formed by the second layer plate 104 and the third layer plate 105. The third layer plate 105 is also provided with several pouring heads 302, which are double-layered cylindrical shell-shaped protrusions. The second cylindrical shell and the first cylindrical shell form rounded corners, and the overall shape is like a drip nozzle with an opening at the top for internal liquid to flow out. Several cylindrical ends from the protrusions of the first layer plate 103 are arranged around the pouring heads 302, with LED beads 301 at their ends. The pouring heads 302 and the surrounding LED beads 301 form a lamp unit 3. Several lamp units 3 are distributed on the lamp plate 1. In use, the interface 101 on the back of the lamp board 1 can be directly connected to the power supply. Considering the device compatibility of this application example, it can also be connected to the power supply via the power cord 2. The power cord 2 includes an adapter 203, which can be connected to the interface 101 on the back of the lamp board 1. An electric wire 202 extends from the tail of the adapter 203. The length of the electric wire 202 is not limited, and a plug 201 is provided at the tail for connecting to the power supply. External liquid flows into the cavity formed by the first layer plate 103 and the second layer plate 104 through the pipe 102, and then flows into the cavity formed by the second layer plate 104 and the third layer plate 105 through another channel pipe, finally flowing out from the pouring head 302. When connected to the power supply alone, the lamp bead 301 lights up, and the light cannot be adjusted. When connected to the pipe 102 alone, the liquid enters the cavity and drips down along the pouring head 302 for irrigation. The two functions are independent and do not interfere with each other, but when liquid is connected, the liquid can dissipate heat from the lamp bead 301. The preferred application scenario is where the plant tray below is positioned at the same location as unit 3 in this application example. The liquid connected to pipe 102 can be water, nutrient solution, or other liquids required for irrigation. The irrigation rate depends on the flow rate and pressure of the liquid connected to pipe 102.
[0135] Admittedly, distributing several LED beads 301 around a watering inlet 302 to form a light unit 3 is for the convenience of designing supplementary lighting coverage and efficiency. The LED beads 301 can also be arbitrarily placed on it. The double-layered design of the lamp plate 1 almost covers the entire interior of the lamp plate 1, so the LED beads 301 can enjoy the heat dissipation effect brought by the liquid no matter where they are placed on the lamp plate. At the same time, the evenly distributed watering heads 302 in the figure are also designed to facilitate the use with other plant trays on the market. In actual use, the distribution and position can be changed according to actual needs.
[0136] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:
[0137] 1. When the LED beads and the water supply work simultaneously, the LED beads can be cooled, allowing for a more compact LED bead distribution design.
[0138] 2. Irrigation can be carried out.
[0139] like Figure 17 The example controller diagram shown in this application is as follows:
[0140] The controller includes:
[0141] The information processing module 4011 is used to process the information received by the information receiving module 4013 and generate corresponding instruction information to be issued to the corresponding module and device, as well as generate feedback information;
[0142] The information sending module 4012 is used to send the feedback information generated by the information processing module 4011 to the outside world;
[0143] The information receiving module 4013 is used to receive information from the outside world and transmit it to the information processing module;
[0144] The lighting control module 4014 is used to receive corresponding instruction information from the information processing module 4011 and drive the lamp beads on the lamp board to work or change their lighting parameters.
[0145] The motor drive module 4015 is used to receive corresponding instruction information from the information processing module 4011 and drive the motor to work so as to drive the double-layer lamp board to work.
[0146] The valve control module 4016 is used to receive corresponding instruction information from the information processing module 4011, and drive the flow control device to work and adjust the valve of the container to control the amount of external liquid entering the container.
[0147] Temperature monitoring module 4017 is used to acquire temperature information of the liquid inside the liquid regulating device and transmit it to the information processing module;
[0148] The flow control module 4018 is used to acquire information on the amount of liquid flowing through the module and transmit it to the information processing module.
[0149] The power supply module 4019 is used to supply power to the information processing module 4011, the information sending module 4012, the information receiving module 4013, the lighting control module 4014, the motor drive module 4015, the valve control module 4016, the temperature monitoring module 4017, and the flow control module 4018.
[0150] like Figure 18 The light control operation flowchart of this application example is shown below:
[0151] Once the power is connected, the system begins operation. Users interact with the control system via mobile devices, inputting desired lighting parameters such as light intensity and light quality. The information receiving module of the controller within the control system receives this input information and transmits it to the information processing module. The information processing module processes this information and generates instruction and feedback information. The instruction information is sent to the LED beads for light control, and the feedback information is sent to the information sending module to be sent to the mobile device for user viewing.
[0152] like Figure 19 The following is an example of the operation flowchart of the position control device of this application:
[0153] Once the power is connected and operation begins, the user interacts with the control system via a mobile device, inputting the desired adjustment parameters. The information receiving module within the control system receives this input and transmits it to the information processing module. The information processing module processes this information and generates instruction and feedback information. The instruction information includes first and second distance information. The first distance information is the distance between the first and second layer panels, and the second distance information is the distance between the second and third layer panels. The instruction information is then sent to the motor drive module, which drives the motor to control the retraction and retraction of the first, second, and third limiting components, thereby changing the position of the first, second, and third layer panels to complete the lamp panel position control operation. The feedback information is then sent to the information sending module and transmitted to the mobile device for the user to view.
[0154] like Figure 20 The flowchart of the flow control device of this application example is shown below:
[0155] Once the power is connected, the system begins operation. The user interacts with the control system via a mobile device, inputting the parameters to be adjusted. The information receiving module of the controller within the control system receives this input information and transmits it to the information processing module. The information processing module processes the information and generates instruction and feedback information. The instruction information is then sent to the valve control module to drive the valve to open and close, thereby controlling the amount of liquid entering and completing the flow control operation. The feedback information is then sent to the information sending module to be sent to the mobile device for the user to view.
[0156] like Figure 21 The following is an example of the operation flowchart of the liquid regulating device of this application:
[0157] Once the power is connected, operation begins. The user interacts with the control system, presets the required watering temperature and volume, and the temperature detection module generates container liquid temperature information. The information receiving module receives this information and transmits it to the information processing module. The information processing module processes this information and generates the external liquid volume and valve opening time, then issues these commands to the valve control module and temperature control module, as well as the corresponding devices: flow meter, valve, and stirrer, to perform the corresponding operations to complete the liquid regulation operation. The specific process is as follows:
[0158] Liquid flows through a pipe into the first cavity formed by the first and second layers of the substrate, cooling the lamp panel while simultaneously heating the liquid to achieve a first-temperature liquid. This liquid then enters the container via a liquid regulating device pipe. A temperature sensor on the stirrer measures the liquid temperature and transmits this information to the processor. The processor processes this information along with user-preset parameters and issues commands to the corresponding modules and devices. Based on the processor's calculation of the required external liquid volume, the valve is opened. Simultaneously, the flow meter is zeroed and begins operation. When the flow meter reaches the specified flow rate, the valve closes. After the valve opens, the stirrer continues to operate until the liquid temperature measured by the temperature sensor reaches the preset temperature, at which point it stops. The pouring valve inside the liquid regulating device pipe forming the second cavity between the second and third layers of the container opens for pouring. If the first-temperature liquid meets the preset temperature, the pouring valve inside the liquid regulating device pipe forming the second cavity between the second and third layers of the container is opened directly for pouring.
[0159] like Figure 22 The following is an example of the automatic adjustment operation flowchart of this application:
[0160] This application example can establish a corresponding database. Users can upload the data of the corresponding crop to the database. When using it, they can select the information group of the corresponding crop and call it to adjust the lighting information and the position of each layer. In addition, watering operations are performed on a regular schedule. Users can manually terminate this process.
[0161] The position control device, flow control device, and liquid regulating device can be used together to control the irrigation rate and the temperature of the irrigation liquid in this application example. The position control device can change the cavity volume by adjusting the cavity size, and the flow control device can change the rate, amount, and pressure of the liquid entering the cavity. This coordinated regulation can effectively increase the irrigation rate adjustment range.
[0162] In addition, this application provides examples of Embodiment 1 and Embodiment 2 to adapt to different environmental needs, but the structure of this application is not limited to Embodiment 1 and Embodiment 2.
[0163] The liquid's temperature rises as it passes through the lamp plate and carries away heat. In winter, the incoming liquid is naturally cold; after being heated by the lamp plate, it reaches the suitable temperature range of 18-25 degrees Celsius for crop irrigation, allowing for direct irrigation. However, in summer, the incoming liquid is naturally hot, making it unsuitable for irrigation after being heated by the lamp plate. Therefore, it enters a liquid conditioning device and is thoroughly mixed with liquid from an external source to cool it down and achieve the required irrigation temperature. In winter, an external liquid source can also be used to heat the liquid before irrigation.
[0164] Therefore, Embodiment 1, with its corresponding control system, is applicable to all four seasons. Embodiment 2, lacking a corresponding control system, allows the liquid to pass through the first cavity formed by the first and second layers and directly enter the second cavity formed by the second and third layers, flowing out through the pouring head. This makes it more suitable for winter use. Alternatively, the initial temperature of the liquid entering the lamp plate can be controlled to enable operation in summer.
