[0001] The present invention relates to the technical field of seedling greenhouse systems and methods, and in particular to an intelligent seedling greenhouse system and method for colored rice. Background Art

[0002] Colored rice contains anthocyanins, a natural pigment found primarily in the seed coat, aleurone layer, and embryo of colored rice. They possess rich nutritional value and biological activity. Research has shown that the yield and anthocyanin content of colored rice are not only related to the variety of colored rice, but also to various climatic factors such as temperature, relative humidity, and light intensity in the growing area. Therefore, to explore the optimal growing conditions for colored rice and further understand the impact of various climatic factors on its yield and anthocyanin content, intelligent greenhouse systems that can precisely control temperature, humidity, and light intensity are essential for research and development of colored rice. Existing intelligent greenhouses mostly utilize high-end industrial integrated temperature and humidity control systems. However, these systems fail to integrate light intensity and ventilation window openings into the control process. Furthermore, changes in light intensity, temperature, and humidity within the greenhouse are closely related to outdoor environmental parameters, and these three factors are highly coupled. Therefore, it is necessary to design an intelligent seedling greenhouse system that comprehensively considers shading, ventilation, and outdoor environmental parameters for precise control.

Humidity adjustment: Adjust the indoor relative humidity through humidification and dehumidification mechanisms.

[0012] Furthermore, the humidity adjustment method in step S5 is as follows: S51. Use the trained ventilation temperature and humidity compensation two-layer deep learning model, take the outdoor temperature, absolute humidity, target ventilation window opening V, outdoor wind speed T1, and indoor absolute humidity AH1 as input features, and output the indoor absolute humidity AH2 after ventilation adjustment; S52, calculate the corresponding indoor relative humidity RH based on the indoor absolute humidity AH2 and the indoor target temperature T; and check whether RH2 is within the preset range. If it is, the humidification mechanism and the dehumidification mechanism will not be started; if it is not, the corresponding indoor target absolute humidity AH is calculated according to the indoor target relative humidity RH and the indoor target temperature T; the difference ΔAH between AH and AH2 is calculated, ΔAH=AH-AH2, and ΔAH is sent to the humidification mechanism or the dehumidification mechanism; S53: The humidifying mechanism or the dehumidifying mechanism performs humidification or dehumidification operation according to the received ΔAH.

[0013] Furthermore, the method of step S2 is: S21. If G1 exceeds the upper limit of the interval and the LED fill lights are in operation, first reduce the brightness of the LED fill lights.

If G1 is lower than the lower limit of the interval, first reduce the shading degree of the sunshade mechanism. If the shading degree of the sunshade mechanism is reduced to 0%, and the indoor light intensity G3 is still lower than the lower limit of the interval, calculate the difference ΔG2 between the indoor target light intensity G and G3; and increase the brightness of the LED fill light according to ΔG2 to meet the requirements; and calculate the difference ΔS between the shading degree S1 of the front sunshade mechanism and the shading degree S2 of the rear sunshade mechanism.

[0016] Further, ; ; .

[0017] Beneficial effects of the present invention: The present invention designs an automatically controllable sunshade mechanism. When the degree of shading needs to be adjusted, the motor is controlled to rotate, driving the screw. Under the restraining action of the slide bar, two moving blocks drive the rotating shaft to move along the axis of the screw. The movement of the rotating shaft drives the gear to move. Under the action of the rack, the gear rotates, thereby driving the rotating shaft. As a result, the rotating shaft drives the sunshade net wrapped around the rotating shaft to move and rotate together, expanding or rewinding the sunshade net, thereby achieving the adjustment of the degree of shading.

[0018] The present invention fully considers the complex coupling influence of the shading mechanism, ventilation mechanism and outdoor environment on indoor temperature, relative humidity and light intensity, and is more accurate in regulating indoor temperature and humidity. It also makes full use of the ventilation mechanism to adjust temperature and humidity, with low energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

The sidewalls of the stopper plate 207 have stopper grooves that mate with one end of the pull-out partition 204. The stoppers 206 and the stopper plate 207 limit the pull-out partition 204.

[0025] Specifically, a handle is provided on the pull-out partition 204 ; and a plurality of locking screws can be used to penetrate the outer partition 203 to tighten the pull-out partition 204 .

[0026] Specifically, each planting unit is equipped with a ventilation mechanism, a dehumidification mechanism, a humidification mechanism, a temperature control mechanism, an LED fill light, a light sensor, a temperature and humidity sensor, and a camera; the central controller is also connected to the storage unit and the communication unit; the central controller is used to perform zoning control on the temperature, humidity, and light intensity of each planting unit.

[0027] Specifically, the storage unit is used to adjust the indoor and outdoor relative humidity, temperature, light intensity, outdoor wind speed, shading degree of the shading mechanism, opening degree of the ventilation mechanism, humidification mechanism, dehumidification mechanism, temperature adjustment mechanism, and brightness of the LED fill light before and after the adjustment for each planting unit.

[0028] Specifically, the ventilation mechanism comprises ventilation windows provided on the side walls of the greenhouse body 1, and a switch mechanism mounted on the side walls for controlling the opening and closing of the ventilation windows. The dehumidification mechanism comprises a rotary dehumidifier, the humidification mechanism comprises a high-pressure mist humidifier, and the temperature control mechanism comprises a heat pump air conditioner.

Example

[0029] A colored rice intelligent seedling greenhouse system, such as Figure 7 As shown, compared with Example 1, only the electric telescopic rod 208 is added, and the locking screw and the handle are cancelled; specifically, the electric telescopic rod 208 with a power-off self-locking function is installed on the outer wall of the outer partition 203; the telescopic end of the electric telescopic rod 208 is connected to the side wall of the pull-out partition 204. Example

[0030] A method for raising colored rice seedlings in an intelligent greenhouse comprises the following steps: S1. Data Collection and Collation: Every unit of time, t, the greenhouse system data is collected for each planting unit. The collected data includes indoor and outdoor relative humidity, temperature, light intensity, outdoor wind speed, shading degree of the shading mechanism, ventilation mechanism opening, and LED fill light brightness. Based on the indoor and outdoor temperature and relative humidity, the corresponding indoor and outdoor absolute humidity is calculated. The shading degree of the shading mechanism and the ventilation mechanism opening range are both [0%-100%]. S2, light intensity adjustment: The central controller determines whether the indoor light intensity G1 is within the preset range Inside; S21. If G1 exceeds the upper limit of the interval and the LED fill lights are in operation, first reduce the brightness of the LED fill lights. If the indoor light intensity G2 still exceeds the upper limit of the interval after all the LED fill lights are turned off, calculate the difference ΔG1 between G2 and the indoor target light intensity G; and increase the shading degree of the sunshade mechanism according to ΔG1, so that the indoor light intensity reaches the target light intensity G when the shading degree of the sunshade mechanism is S1; and calculate the difference ΔS between the shading degree S1 of the sunshade mechanism before adjustment and the shading degree S2 of the sunshade mechanism after adjustment; S22. If G1 is lower than the lower limit of the interval, first reduce the shading degree of the sunshade mechanism. If the indoor light intensity G3 is still lower than the lower limit of the interval when the shading degree of the sunshade mechanism is reduced to 0%, calculate the difference ΔG2 between the indoor target light intensity G and G3; and increase the brightness of the LED fill light according to ΔG2 to meet the requirement; and calculate the difference ΔS between the shading degree S1 of the front sunshade mechanism and the shading degree S2 of the rear sunshade mechanism; The sunshade mechanism adjusts based on indoor light intensity, prioritizing outdoor natural light to meet indoor lighting needs. When outdoor natural light is insufficient, LED fill lights are used to enhance lighting. When outdoor natural light is too strong, even without the LED fill lights, the sunshade mechanism will only activate when the indoor light intensity still exceeds the upper limit of the range. When the indoor light intensity falls below the lower limit of the range, the sunshade mechanism first determines whether the shading degree can be reduced. If so, the shading degree is lowered. When the shading degree drops to 0%, and the indoor light intensity still falls below the lower limit of the range, the brightness of the LED fill lights is increased.

[0031] S3. Calculate shading temperature compensation: Use the trained shading temperature compensation deep learning model, take S1, S2, ΔS, outdoor temperature, outdoor light intensity, and indoor temperature T1 before adjustment as input features, and output the indoor temperature T2 after light adjustment; Changes in shading often lead to changes in indoor temperature. Using a deep learning model, we can calculate the impact of shading on indoor temperature and factor this change into the temperature adjustment process, improving temperature regulation accuracy and saving energy. S4. Temperature adjustment: S41: Determine whether the temperature value T2 after sunshade compensation is within a preset range If it exceeds the range, the difference ΔT1 between the indoor target temperature T and T2 is calculated, ΔT1=T-T2; S42. Use the trained ventilation temperature and humidity compensation two-layer deep learning model, take the outdoor temperature, relative humidity, absolute humidity, wind speed, T1, ΔT1, indoor relative humidity, and absolute humidity as input features, and output the corresponding target ventilation window opening V; S43, preset the mapping relationship between the outdoor wind speed and the maximum allowable ventilation window opening; calculate the current maximum allowable ventilation window opening V based on the current outdoor wind speed A ; Determine whether the output target ventilation window opening V exceeds the current maximum allowable ventilation window opening V A ; S44, if v=0%, then take v=0%, outdoor temperature, relative humidity, absolute humidity, wind speed, T1, indoor relative humidity, absolute humidity as input features, and output the indoor temperature T3 after ventilation adjustment; if T3 is within the preset range If T3 exceeds the preset range, the ventilation mechanism will be activated to completely close the ventilation window and the temperature adjustment mechanism will not be activated; if ... , while the ventilation unit is in operation, it calculates the difference ΔT2 between T3 and the indoor target temperature T, and sends ΔT2 to the temperature adjustment mechanism; the temperature adjustment mechanism starts the cooling or heating mode according to the received ΔT2 to adjust the temperature; S45, if V does not exceed V A , and v 0%, the ventilation mechanism adjusts the ventilation window opening according to the received target ventilation window opening V and the current ventilation window opening; and the temperature adjustment mechanism is not activated; S46, if V exceeds V A , then update the target ventilation window opening V, let V=V A ; Then v=V A , outdoor temperature, relative humidity, absolute humidity, wind speed, T1, indoor relative humidity, absolute humidity are input features, and the output is the indoor temperature T3 after ventilation adjustment; if T3 is within the preset range The ventilation mechanism will be activated and the ventilation window opening will be adjusted to V A , and does not start the temperature adjustment mechanism; if T3 exceeds the preset range , while the ventilation unit is in operation, it calculates the difference ΔT2 between T3 and the indoor target temperature T, and sends ΔT2 to the temperature adjustment mechanism; the temperature adjustment mechanism starts the cooling or heating mode according to the received ΔT2 to adjust the temperature; Ventilation is an effective way to regulate temperature and humidity, and can save energy to a great extent. However, the effects of ventilation on temperature, relative humidity, and absolute humidity are strongly coupled, so it is crucial to clarify the effects and relationships between them. In this embodiment, temperature is used as the driving force, and the effect of changes in shading on temperature is taken into account to determine the opening of the ventilation mechanism; the predicted opening of the ventilation mechanism is compared with 0% and the maximum ventilation opening allowed under different outdoor wind speed conditions, and the outdoor temperature corresponding to the ventilation opening under boundary conditions is given, fully considering the situation that relying solely on adjusting the opening of the ventilation mechanism is not enough to adjust the indoor temperature to the indoor target temperature.

[0032] S5. Humidity adjustment: S51. Use the trained ventilation temperature and humidity compensation two-layer deep learning model, take the outdoor temperature, absolute humidity, target ventilation window opening V, outdoor wind speed T1, and indoor absolute humidity AH1 as input features, and output the indoor absolute humidity AH2 after ventilation adjustment; S52, calculate the corresponding indoor relative humidity RH based on the indoor absolute humidity AH2 and the indoor target temperature T; and check whether RH2 is within the preset range. If the humidity is within the range of 0 to 1, the humidification mechanism and the dehumidification mechanism will not be started; if the humidity is not within the range of 0 to 1, the corresponding indoor target absolute humidity AH will be calculated according to the indoor target relative humidity RH and the indoor target temperature T; the difference ΔAH between AH and AH2 will be calculated, ΔAH=AH-AH2, and ΔAH will be sent to the humidification mechanism or the dehumidification mechanism; when ΔAH is a positive number, the humidification mechanism will be turned on; when ΔAH is a negative number, the dehumidification mechanism will be turned on.

[0033] S53: The humidifying mechanism or the dehumidifying mechanism performs humidification or dehumidification operation according to the received ΔAH.

[0034] Since relative humidity is related to both absolute humidity and temperature, even if absolute humidity remains constant, changes in temperature will cause relative humidity to change. Therefore, controlling relative humidity directly is not accurate. In this embodiment, a deep learning model is used to calculate the change in indoor absolute humidity before and after ventilation adjustment, and the absolute humidity is used to control the operation of the humidification mechanism or dehumidification mechanism.

[0035] Specifically, after a unit of time t, the actual indoor temperature, relative humidity, and light intensity are compared with their corresponding ranges. If any of the three exceed the range, an abnormal control warning message is generated. The warning message is then sent to the manager or management platform via the communication unit, allowing management personnel to investigate the abnormal situation.

[0036] Specifically, the indoor target temperature T is taken from Indoor; the indoor target light intensity G is taken from Indoor target relative humidity RH is taken from Inside.

[0037] In this embodiment ; ; In another embodiment, T, G, and RH may also be any values ​​within the range.

[0038] The present invention can also be applied to the cultivation of crops other than colored rice.

[0039] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.

Data Collection and Collation: Every unit of time, t, the greenhouse system data is collected for each planting unit. The collected data includes indoor and outdoor relative humidity, temperature, light intensity, outdoor wind speed, shading degree of the shading mechanism, ventilation mechanism opening, and LED fill light brightness. Based on the indoor and outdoor temperature and relative humidity, the corresponding indoor and outdoor absolute humidity is calculated. The shading degree of the shading mechanism and the ventilation mechanism opening range are both [0%-100%]. S2. Light intensity adjustment: The central controller determines whether the indoor light intensity G1 is within a preset range. If it is outside the range, it adjusts the brightness of the LED fill light or the shading degree of the sunshade mechanism; and calculates the difference ΔS between the shading degree S1 of the front shading mechanism and the shading degree S2 of the rear shading mechanism, where ΔS = S2 - S1; S3. Calculate shading temperature compensation: Use the trained shading temperature compensation deep learning model, take S1, S2, ΔS, outdoor temperature, outdoor light intensity, and indoor temperature T1 before adjustment as input features, and output the indoor temperature T2 after light adjustment; S4. Temperature adjustment: S41, determining whether the temperature value T2 after shading compensation is within a preset range. If it is outside the range, calculating the difference ΔT1 between the indoor target temperature T and T2, where ΔT1 = T - T2; S42. Use the trained ventilation temperature and humidity compensation two-layer deep learning model, take the outdoor temperature, relative humidity, absolute humidity, wind speed, T1, ΔT1, indoor relative humidity, and absolute humidity as input features, and output the corresponding target ventilation window opening V; S43, presetting a mapping relationship between the outdoor wind speed and the maximum allowable ventilation window opening; calculating the current maximum allowable ventilation window opening VA based on the current outdoor wind speed; and determining whether the output target ventilation window opening V exceeds the current maximum allowable ventilation window opening VA; S44. If v = 0%, then using v = 0%, the outdoor temperature, relative humidity, absolute humidity, wind speed, T1, the indoor relative humidity, and absolute humidity as input features, output the indoor temperature T3 after ventilation adjustment; if T3 is within the preset range, the ventilation mechanism is activated to completely close the ventilation window, and the temperature adjustment mechanism is not activated; if T3 exceeds the preset range, the ventilation unit is activated and the difference ΔT2 between T3 and the indoor target temperature T is calculated and sent to the temperature adjustment mechanism; the temperature adjustment mechanism activates the cooling or heating mode based on the received ΔT2 to adjust the temperature; S45.
