Description

Technical Field

[0001] The present invention belongs to the technical field of agriculture, and particularly relates to an automatic control method, a terminal and a storage medium for a thermal insulation quilt of a solar greenhouse. Background Art

[0002] With its excellent heat preservation performance and low-cost advantage, the energy-saving solar greenhouse has become the core carrier of current facility agriculture and plays an important role in the production of crops such as vegetables and fruits. However, the energy-saving solar greenhouse still has significant shortcomings: its structural design relies on traditional experience, the level of environmental regulation automation is low, and the growth of crops is severely restricted by external meteorological conditions. Especially in the context of climate change, the frequency and intensity of extreme weather (such as cold snaps, continuous rainy days, heavy snow, etc.) have increased significantly, resulting in drastic fluctuations in the air temperature and ground temperature inside the greenhouse, which can easily cause problems such as low-temperature cold damage, freezing damage or excessive respiratory consumption of facility crops, directly threatening the stability of yield and quality. For example, covering the thermal insulation quilt too early may cause high temperature at night, increasing the respiratory consumption of crops, while covering it too late will lead to too fast heat dissipation, both of which will reduce economic benefits. Therefore, how to scientifically determine the opening and covering time of the thermal insulation quilt of the solar greenhouse to achieve the efficient utilization of light and heat resources and the scientific prevention and control of disaster risks is the key technology for improving the quality and efficiency of current facility agriculture.

[0003] Currently, the decision-making on the opening, covering and rolling time of the thermal insulation quilt of the solar greenhouse mainly relies on two traditional methods: one is manual observation, that is, producers make subjective judgments based on experience combined with simple meteorological data (such as outdoor temperature, light intensity). It relies on individual experience, lacks a standardized operation process, and is prone to crop freezing damage or energy waste due to misjudgment; the other is to use a preset sunrise and sunset time formula (such as T = T sunrise / T sunset ± X minutes) to control the rolling and unrolling time of the thermal insulation quilt, lacking dynamic environmental response and not considering the impact of weather such as continuous cloudy days and extreme low temperatures on the actual opening and covering time, which may lead to insufficient heat storage in the greenhouse or crop freezing. Summary of the Invention

[0004] Aiming at the defects in the prior art that rely on manual observation to determine the opening and covering time of the thermal insulation quilt, lack a standardized operation process, and are prone to crop freezing damage or energy waste due to misjudgment; or use the sunrise and sunset time formula to control the rolling and unrolling time of the thermal insulation quilt, lack dynamic environmental response, and may lead to insufficient heat storage in the greenhouse or crop freezing, the present invention provides an automatic control method, a terminal and a storage medium for a thermal insulation quilt of a solar greenhouse to solve the above technical problems.

[0005] In the first aspect, the present invention provides an automatic control method for a thermal insulation quilt of a solar greenhouse, including:

[0008] Judge whether the solar greenhouse enters the season of covering the heat preservation quilt according to the photosynthetically active radiation at the same time inside the obtained solar greenhouse; if so, input the photosynthetically active radiation at the same time inside the obtained solar greenhouse into the pre-built second heat preservation quilt state judgment model, and output the state of the heat preservation quilt;

[0009] Compare the state of the heat preservation quilt output by the first heat preservation quilt state judgment model with the state of the heat preservation quilt output by the second heat preservation quilt state judgment model. If the states of the heat preservation quilt output by both are the same, and both are the initial uncovering state of the heat preservation quilt or both are the initial covering state of the heat preservation quilt, then take this moment as the uncovering moment or the covering moment of the heat preservation quilt, and output and save it;

[0014] If both are the case, it is determined that the season of covering the heat preservation quilt has not been entered;

[0015] Judge whether the total radiation outside the solar greenhouse corresponding to any moment during the first preset time period is greater than the first preset total radiation, and judge whether the total radiation inside the solar greenhouse corresponding to the same moment is less than the second preset total radiation, and judge whether the total radiation outside the solar greenhouse corresponding to any moment during the second preset time period in the afternoon of the same day is greater than the first preset total radiation, and judge whether the total radiation inside the solar greenhouse corresponding to the same moment is less than the second preset total radiation; the first preset total radiation is less than the second preset total radiation;

[0020] If the total solar radiation outside the solar greenhouse is the first preset total radiation, output that the heat-insulating quilt is in the covered state;

[0021] If the total solar radiation outside the solar greenhouse is greater than the first preset total radiation, and the total solar radiation inside the solar greenhouse at the same moment is less than the second preset total radiation, output that the heat-insulating quilt is in the covered state;

[0022] If the total solar radiation outside the solar greenhouse is greater than the first preset total radiation, and the total solar radiation inside the solar greenhouse at the same moment is greater than the second preset total radiation, the minute change rate of the air temperature outside the solar greenhouse is greater than the preset first air temperature minute change rate, and the minute change rate of the air temperature inside the solar greenhouse is less than the preset first air temperature minute change rate, output that the heat-insulating quilt is in the initial uncovered state;

[0030] Among them, is the minute change rate of air temperature outside the solar greenhouse; is the air temperature data at the current moment outside the solar greenhouse; is the air temperature data at a preset time interval from the current moment outside the solar greenhouse.

[0031] A further improvement of this technical solution is to determine whether the solar greenhouse enters the season of covering the insulation quilt according to the photosynthetically active radiation at the same moment in the solar greenhouse. The method includes:

[0032] Obtain the sunrise time of the day;

[0033] Calculate the minute change rate of photosynthetically active radiation in the solar greenhouse according to the photosynthetically active radiation at the same moment in the solar greenhouse;

[0034] Judge whether the minute change rate of photosynthetically active radiation in the solar greenhouse is greater than the preset first minute change rate of photosynthetically active radiation, and judge whether the photosynthetically active radiation corresponding to a preset time interval before the current moment in the solar greenhouse is less than the preset first photosynthetically active radiation;

[0035] If both are true, it is determined that the insulation quilt is in the initial uncovered state;

[0036] Judge whether the moment when the insulation quilt is in the initial uncovered state is later than the sunrise time of the day, and calculate the time difference between the two;

[0037] If the moment when the insulation quilt is in the initial uncovered state is later than the sunrise time of the day, and the time difference between the two is greater than the preset first time difference, it is determined that the season of covering the insulation quilt has entered.

[0038] A further improvement of this technical solution is that the formula for calculating the minute change rate of photosynthetically active radiation in the solar greenhouse according to the photosynthetically active radiation at the same moment in the solar greenhouse is:

[0039] ;

[0040] Among them, is the minute variation rate of photosynthetically active radiation in the solar greenhouse; is the photosynthetically active radiation at the current moment in the solar greenhouse; is the photosynthetically active radiation at a preset time interval from the current moment in the solar greenhouse.

[0041] A further improvement of this technical solution is to input the photosynthetically active radiation at the same moment in the solar greenhouse obtained into a pre-built second insulation quilt state judgment model to output the state of the insulation quilt. The method includes:

[0042] Judge the state of the insulation quilt according to the photosynthetically active radiation at the same moment in the solar greenhouse obtained, the photosynthetically active radiation corresponding to the preset time interval from the current moment in the solar greenhouse, and the calculated minute variation rate of photosynthetically active radiation in the solar greenhouse:

[0043] If the photosynthetically active radiation at the same moment in the solar greenhouse is equal to the preset second photosynthetically active radiation, output that the insulation quilt is in the covered state; and the second photosynthetically active radiation is less than the first photosynthetically active radiation;

[0044] If the minute variation rate of photosynthetically active radiation in the solar greenhouse is less than the preset first minute variation rate of photosynthetically active radiation, and the photosynthetically active radiation corresponding to the preset time interval before the current moment in the solar greenhouse is less than the preset first photosynthetically active radiation, output that the insulation quilt is in the covered state;

[0045] If the minute variation rate of photosynthetically active radiation in the solar greenhouse is less than the preset first minute variation rate of photosynthetically active radiation, and the photosynthetically active radiation at the same moment in the solar greenhouse is less than the preset first photosynthetically active radiation, output that the insulation quilt is in the covered state;

[0047] If the minute variation rate of photosynthetically active radiation in the solar greenhouse is greater than the preset first minute variation rate of photosynthetically active radiation, and the photosynthetically active radiation corresponding to the preset time interval before the current moment in the solar greenhouse is greater than the preset first photosynthetically active radiation, output that the insulation quilt is in the uncovered state;

[0048] If the minute variation rate of photosynthetically active radiation in the solar greenhouse is less than the preset second minute variation rate of photosynthetically active radiation, and the photosynthetically active radiation corresponding to the preset time interval after the current moment in the solar greenhouse is less than the preset first photosynthetically active radiation, output that the insulation quilt is in the initial covered state; and the second minute variation rate of photosynthetically active radiation is less than the first minute variation rate of photosynthetically active radiation.

[0049] A further improvement of this technical solution is to compare the state of the insulation quilt output by the first insulation quilt state judgment model with the state of the insulation quilt output by the second insulation quilt state judgment model. If the states of the insulation quilt output by both are the same, and both are the initial uncovering state of the insulation quilt or both are the initial covering state of the insulation quilt, then this moment is taken as the uncovering moment or the covering moment of the insulation quilt, and the output is saved. The method includes:

[0050] When the first insulation quilt state judgment model outputs that the insulation quilt is in the initial uncovering state, and the second insulation quilt state judgment model outputs that the insulation quilt is in the initial uncovering state, then the moment when the insulation quilt is in the initial uncovering state is recorded as the uncovering time of the insulation quilt;

[0051] When the first insulation quilt state judgment model outputs that the insulation quilt is in the initial covering state, and the second insulation quilt state judgment model outputs that the insulation quilt is in the initial covering state, then the moment when the insulation quilt is in the initial covering state is recorded as the covering time of the insulation quilt;

[0052] Output and save the uncovering time and covering time of the insulation quilt.

[0053] [[ID=..]]Thirdly, a terminal is provided, including:

[0058] The beneficial effects of the present invention are as follows. By integrating multi-dimensional meteorological parameters (air temperature, total radiation, photosynthetically active radiation) inside and outside the greenhouse and a dual-model collaborative decision-making mechanism, the present invention effectively breaks through the limitations of traditional methods that rely on single parameters or manual experience to decide the uncovering and covering times of the insulation quilt in a solar greenhouse. That is, a first model based on the collaborative analysis of total radiation and air temperature and a second model based on the dynamic tracking of photosynthetically active radiation are constructed. Through a cross-validation mechanism, the two models ensure that the extraction results of the uncovering and covering times of the insulation quilt have high reliability and high precision.

[0059] In addition, the design principle of the present invention is reliable, the structure is simple, and it has a very wide application prospect. Description of the Drawings

[0065] Figure 1 It is a schematic flowchart of an automatic control method for a solar greenhouse insulation quilt provided by the present invention. According to different requirements, the order of the steps in this flowchart can be changed, and some can be omitted.

[0066] As Figure 1 shown, the method includes:

[0067] Step 110, automatically obtain the meteorological data inside and outside the solar greenhouse at a preset time interval through the climate observation stations installed inside and outside the solar greenhouse. The meteorological data includes air temperature and total radiation, and obtain the photosynthetically active radiation inside the solar greenhouse;

[0068] Step 120, determine whether the solar greenhouse enters the season of covering the insulation quilt according to the total radiation obtained inside and outside the solar greenhouse; if so, input the air temperature and total radiation obtained inside and outside the solar greenhouse into a pre-established first insulation quilt state judgment model, and output the state of the insulation quilt;

[0069] Step 130: Determine whether the solar greenhouse has entered the season for covering the insulation quilt based on the photosynthetically active radiation obtained at the same time in the solar greenhouse; if so, input the photosynthetically active radiation obtained at the same time in the solar greenhouse into the pre-established second insulation quilt state judgment model to output the state of the insulation quilt.

[0070] Step 140: Compare the state of the insulation quilt output by the first insulation quilt state judgment model with the state of the insulation quilt output by the second insulation quilt state judgment model. If the states of the insulation quilt output by both are the same, and both are the initial uncovering state of the insulation quilt or both are the initial covering state of the insulation quilt, then take this moment as the uncovering moment or the covering moment of the insulation quilt, and output and save it.

[0071] Step 150: Control the uncovering of the insulation quilt according to the obtained uncovering moment of the insulation quilt, or control the covering of the insulation quilt according to the obtained covering moment of the insulation quilt.

[0072] For the convenience of understanding the present invention, the principle of the automatic control method for the insulation quilt of the solar greenhouse of the present invention is described below, in combination with the process of automatically extracting the uncovering and covering times of the insulation quilt of the solar greenhouse in the embodiment, to further describe the automatic control method for the insulation quilt of the solar greenhouse provided by the present invention.

[0073] Specifically, determining whether the solar greenhouse has entered the season for covering the insulation quilt according to the total radiation obtained inside and outside the solar greenhouse, the method includes:

[0074] S1211: Obtain the total radiation inside and outside the solar greenhouse during the first preset time period in the early morning and the second preset time period in the afternoon of the same day.

[0075] S1212: Judge whether the total radiation inside and outside the solar greenhouse corresponding to any moment during the first preset time period is greater than the first preset total radiation, and judge whether the total radiation inside and outside the solar greenhouse corresponding to any moment during the second preset time period in the afternoon of the same day is less than the first preset total radiation.

[0076] S1213: If both are the case, it is determined that the season for covering the insulation quilt has not entered.

[0077] S1214: Judge whether the total radiation outside the solar greenhouse corresponding to any moment during the first preset time period is greater than the first preset total radiation, and judge whether the total radiation inside the solar greenhouse corresponding to the same moment is less than the second preset total radiation, and judge whether the total radiation outside the solar greenhouse corresponding to any moment during the second preset time period in the afternoon of the same day is greater than the first preset total radiation, and judge whether the total radiation inside the solar greenhouse corresponding to the same moment is less than the second preset total radiation; the first preset total radiation is less than the second preset total radiation.

[0078] S1215. If the total radiation outside the solar greenhouse corresponding to any moment within the first preset time period is greater than the first preset total radiation, and the total radiation inside the solar greenhouse corresponding to the same moment is less than the second preset total radiation, and the total radiation outside the solar greenhouse corresponding to any moment within the second preset time period in the afternoon of the same day is greater than the first preset total radiation, and the total radiation inside the solar greenhouse corresponding to the same moment is less than the second preset total radiation, it is determined that the heat preservation covering season has begun.

[0079] For example, the total radiation inside and outside the solar greenhouse corresponding to any time in the time period from 4:00 to 8:00 in the morning (the first preset time period) is obtained, and the total radiation inside and outside the solar greenhouse corresponding to any time in the time period from 17:00 to 19:00 in the afternoon of the same day (the second preset time period) is obtained; if the total radiation inside and outside the solar greenhouse corresponding to any time in the time period from 4:00 to 8:00 in the morning is greater than 0W / (m•m), and the total radiation inside and outside the solar greenhouse corresponding to any time in the time period from 17:00 to 19:00 in the afternoon of the same day is less than 0W / (m•m), it is determined that the insulation blanket covering season has not begun (the first insulation blanket status judgment model outputs 0); if it is at 4:00 in the morning, If the total radiation outside the solar greenhouse at any time during the period from 4 a.m. to 8 a.m. is greater than 0 W / (m•m), and the total radiation inside the solar greenhouse at the same time during the period from 4 a.m. to 8 a.m. is less than 5 W / (m•m), and if the total radiation outside the solar greenhouse at any time during the period from 5 p.m. to 7 p.m. is greater than 0 W / (m•m), and the total radiation inside the solar greenhouse at the same time during the period from 5 p.m. to 7 p.m. is less than 5 W / (m•m), it is determined that the thermal insulation blanket covering season has begun (output g of the first thermal insulation blanket status judgment model); and judgment needs to be strengthened in April, October, and November each year.

[0080] Furthermore, the obtained air temperature and total radiation inside and outside the solar greenhouse are input into a pre-built first insulation blanket state judgment model to output the state of the insulation blanket. The method includes:

[0081] S1221. Calculating the corresponding minute temperature variation rate inside and outside the solar greenhouse based on the acquired temperature data inside and outside the solar greenhouse;

[0082] S1222. Determine the state of the insulation blanket based on the minute temperature change rate and total radiation inside and outside the greenhouse at the same time:

[0083] If the total radiation outside the solar greenhouse is the first preset total radiation, the output insulation blanket is in the covering state;

[0084] If the total radiation outside the solar greenhouse is greater than the first preset total radiation, and at the same time the total radiation inside the solar greenhouse is less than the second preset total radiation, the output insulation blanket is in the covering state;

[0085] If the total radiation outside the solar greenhouse is greater than the first preset total radiation, and at the same time the total radiation inside the solar greenhouse is greater than the second preset total radiation, the minute change rate of the air temperature outside the solar greenhouse is greater than the preset first minute change rate of the air temperature, and the minute change rate of the air temperature inside the solar greenhouse is less than the preset first minute change rate of the air temperature, then it is output that the thermal insulation quilt is in the initial uncovered state;

[0086] If the total radiation outside the solar greenhouse is greater than the first preset total radiation, and at the same time the total radiation inside the solar greenhouse is greater than the second preset total radiation, the minute change rate of the air temperature outside the solar greenhouse is greater than the preset first minute change rate of the air temperature, and the minute change rate of the air temperature inside the solar greenhouse is greater than the preset first minute change rate of the air temperature, then it is output that the thermal insulation quilt is in the uncovered state;

[0087] If the total radiation outside the solar greenhouse is greater than the second preset total radiation, and at the same time the total radiation inside the solar greenhouse is equal to the second preset total radiation, the minute change rate of the air temperature outside the solar greenhouse is less than the preset first minute change rate of the air temperature, and the minute change rate of the air temperature inside the solar greenhouse is less than the preset first minute change rate of the air temperature, then it is output that the thermal insulation quilt is in the initial covered state.

[0088] Specifically, the formula for calculating the minute change rate of the air temperature inside the solar greenhouse according to the obtained air temperature data inside the solar greenhouse is:

[0089] ;

[0090] Among them, is the minute change rate of the air temperature inside the solar greenhouse; is the air temperature data at the current moment inside the solar greenhouse; is the air temperature data at a preset time interval from the current moment inside the solar greenhouse;

[0091] The formula for calculating the minute change rate of the air temperature outside the solar greenhouse according to the obtained air temperature data outside the solar greenhouse is:

[0092] ;

[0093] Among them, is the minute change rate of the air temperature outside the solar greenhouse; is the air temperature data at the current moment outside the solar greenhouse; is the air temperature data at a preset time interval from the current moment outside the solar greenhouse.

[0094] For example, if the total solar radiation outside the solar greenhouse is equal to 0 W / (m•m) (the first preset total solar radiation), the pre-established first insulation quilt state judgment model outputs 1 (i.e., the insulation quilt is in the covered state); if the total solar radiation outside the solar greenhouse > 0 W / (m•m) and the total solar radiation inside the solar greenhouse at the same time < 5 W / (m•m) (the second preset total solar radiation), it continues to output 1; if the total solar radiation outside the solar greenhouse > 0 W / (m•m) and the total solar radiation inside the solar greenhouse at the same time > 5 W / (m•m), and at the same time Qt-out (the minute change rate of the air temperature outside the solar greenhouse) > 0 (the first minute change rate of the air temperature) and Qt-in (the minute change rate of the air temperature inside the solar greenhouse) < 0, then output 2, and the moment when the first 2 is output is marked as the initial uncovering state of the insulation quilt, and the time of this moment is recorded; if the total solar radiation outside the solar greenhouse > 0 W / (m•m) and the total solar radiation inside the solar greenhouse > 5 W / (m•m), and Qt-out > 0 and Qt-in > 0, then output 3 (i.e., the insulation quilt is in the uncovered state); if the total solar radiation outside the solar greenhouse > 5 W / (m•m) and the total solar radiation inside the solar greenhouse = 5 W / (m•m), and Qt-out < 0 and Qt-in < 0, then output 4 (i.e., output that the insulation quilt is in the initial covered state).

[0095] The present invention can accurately judge whether the solar greenhouse enters the season of covering the insulation quilt by obtaining the total solar radiation data inside and outside the solar greenhouse and combining with the radiation threshold within a preset time period. Specifically, by analyzing the total solar radiation data in the early morning and afternoon, it can be judged whether the insulation quilt needs to be used in the current season. This method avoids the uncertainty of relying on artificial experience or single parameter judgment in the traditional method, and improves the accuracy and reliability of the judgment (the uncovered time and covered time of the insulation quilt extracted can also be used for subsequent agricultural research). In addition, the present invention can dynamically respond to environmental changes and timely adjust the uncovering and covering time of the insulation quilt through high-frequency data collection (once every 5 minutes) and real-time calculation. For example, when it suddenly becomes sunny after continuous cloudy days, it can quickly capture the change in light intensity and adjust the uncovering time of the insulation quilt, and uncover the insulation quilt in time according to the adjusted uncovering time of the insulation quilt to avoid poor growth of crops due to insufficient light. Similarly, when the temperature drops suddenly, adjust the covering time of the insulation quilt, and cover the insulation quilt in time according to the adjusted covering time of the insulation quilt to reduce heat loss and ensure the temperature stability in the greenhouse.

[0096] In addition, to judge whether the solar greenhouse enters the season of covering the insulation quilt according to the simultaneously obtained photosynthetically active radiation inside the solar greenhouse, the method includes:

[0097] S1311. Obtain the sunrise time of the day;

[0098] S1312. Calculate the minute change rate of the photosynthetically active radiation inside the solar greenhouse according to the simultaneously obtained photosynthetically active radiation inside the solar greenhouse;

[0099] S1313. Determine whether the minute change rate of photosynthetically active radiation in the solar greenhouse is greater than a preset first minute change rate of photosynthetically active radiation, and determine whether the photosynthetically active radiation corresponding to a preset time interval before the current moment in the solar greenhouse is less than a preset first photosynthetically active radiation;

[0100] S1314. If both are true, determine that the thermal insulation quilt is in the initial uncovered state;

[0101] S1315. Determine whether the moment when the thermal insulation quilt is in the initial uncovered state is later than the sunrise time of the current day, and calculate the time difference between the two;

[0102] S1316. If the moment when the thermal insulation quilt is in the initial uncovered state is later than the sunrise time of the current day, and the time difference between the two is greater than a preset first time difference, determine that it enters the thermal insulation quilt covering season.

[0103] Specifically, the formula for calculating the minute change rate of photosynthetically active radiation in the solar greenhouse according to the photosynthetically active radiation at the same moment in the solar greenhouse is:

[0104] ;

[0105] where, is the minute change rate of photosynthetically active radiation in the solar greenhouse; is the photosynthetically active radiation at the current moment in the solar greenhouse; is the photosynthetically active radiation corresponding to a preset time interval from the current moment in the solar greenhouse.

[0106] For example, if for the first time > 1 (preset first minute change rate of photosynthetically active radiation) and the photosynthetically active radiation in the solar greenhouse at 5 minutes from the current moment < 5 μmol / (m²•s) (preset first photosynthetically active radiation), then the second thermal insulation quilt state judgment model outputs 2 (i.e., the thermal insulation quilt is in the initial uncovered state); if the moment of outputting 2 is later than the sunrise moment of the current day, and the time difference between the two is greater than the preset first time difference, then the second thermal insulation quilt state judgment model outputs g (and it is necessary to strengthen the judgment in October, November, and April).

[0107] Furthermore, input the obtained photosynthetically active radiation at the same moment in the solar greenhouse into a pre - established second thermal insulation quilt state judgment model to output the state of the thermal insulation quilt. The method includes:

[0108] S1321. Determine the state of the thermal insulation quilt according to the obtained photosynthetically active radiation at the same moment in the solar greenhouse, the photosynthetically active radiation corresponding to a preset time interval from the current moment in the solar greenhouse, and the calculated minute change rate of photosynthetically active radiation in the solar greenhouse:

[0109] If the photosynthetically active radiation (PAR) in the solar greenhouse at the same time is equal to the preset second PAR, the output is that the thermal insulation quilt is in the covered state; and the second PAR is less than the first PAR.

[0110] If the minute change rate of PAR in the solar greenhouse is less than the preset first minute change rate of PAR, and the PAR corresponding to the preset time interval before the current time in the solar greenhouse is less than the preset first PAR, the output is that the thermal insulation quilt is in the covered state.

[0111] If the minute change rate of PAR in the solar greenhouse is less than the preset first minute change rate of PAR, and the PAR in the solar greenhouse at the same time is less than the preset first PAR, the output is that the thermal insulation quilt is in the covered state.

[0112] If the minute change rate of PAR in the solar greenhouse is greater than the preset first minute change rate of PAR, and the PAR corresponding to the preset time interval before the current time in the solar greenhouse is less than the preset first PAR, the output is that the thermal insulation quilt is in the initial uncovered state.

[0113] If the minute change rate of PAR in the solar greenhouse is greater than the preset first minute change rate of PAR, and the PAR corresponding to the preset time interval before the current time in the solar greenhouse is greater than the preset first PAR, the output is that the thermal insulation quilt is in the uncovered state.

[0114] If the minute change rate of PAR in the solar greenhouse is less than the preset second minute change rate of PAR, and the PAR corresponding to the preset time interval after the current time in the solar greenhouse is less than the preset first PAR, the output is that the thermal insulation quilt is in the initial covered state; and the second minute change rate of PAR is less than the first minute change rate of PAR.

[0115] For example, if the PAR in the solar greenhouse = 0 µmol / (m²•s) (the second PAR), the second thermal insulation quilt state judgment model outputs 1 (i.e., the thermal insulation quilt is in the covered state); if the minute change rate of PAR in the solar greenhouse < 1 (the preset first minute change rate of PAR) and the PAR corresponding to 5 minutes before the current time in the solar greenhouse < 5 µmol / (m²•s) (the preset first PAR), the second thermal insulation quilt state judgment model outputs 1; if the minute change rate of PAR in the solar greenhouse < 1 and the PAR in the solar greenhouse < 5 µmol / (m²•s), the second thermal insulation quilt state judgment model outputs 1 (i.e., the thermal insulation quilt is in the covered state); if > 1 and the photosynthetically active radiation in the solar greenhouse 5 minutes before the current moment < 5 μmol / (m²•s), then the second insulation quilt state judgment model outputs 2 (i.e., the insulation quilt is in the initial uncovered state); if the minute change rate of the photosynthetically active radiation in the solar greenhouse > 1 and the photosynthetically active radiation corresponding to 5 minutes before the current moment in the solar greenhouse > 5 μmol / (m²•s), then the second insulation quilt state judgment model outputs 3 (i.e., the insulation quilt is in the uncovered state); if the minute change rate of the photosynthetically active radiation in the solar greenhouse < -1 (the second minute change rate of photosynthetically active radiation) (last time) and the photosynthetically active radiation corresponding to 5 minutes after the current moment in the solar greenhouse < 5 μmol / (m²•s), the second insulation quilt state judgment model outputs 4 (i.e., the insulation quilt is in the initial covered state).

[0116] The lighting conditions in the greenhouse are dynamically changing, especially during seasonal alternations, sunny and cloudy changes, etc. By calculating the minute change rate of photosynthetically active radiation, the present invention can monitor the changes in lighting conditions in real time and dynamically adjust the uncovering and covering times of the insulation quilt. For example, when it suddenly clears up after a rainy day, it can quickly capture the increase in light intensity and adjust the uncovering time of the insulation quilt, and uncover the insulation quilt in a timely manner according to the adjusted uncovering time of the insulation quilt to ensure that the crops can make full use of light for photosynthesis. This dynamic response ability significantly improves the flexibility and adaptability of greenhouse management.

[0117] Finally, compare the insulation quilt state output by the first insulation quilt state judgment model with the state of the insulation quilt output by the second insulation quilt state judgment model. If the insulation quilt states output by both are the same, and both are the initial uncovered state of the insulation quilt or both are the initial covered state of the insulation quilt, then take this moment as the uncovering moment or the covering moment of the insulation quilt, and output and save it. The method includes:

[0118] S141. When the first insulation quilt state judgment model outputs that the insulation quilt is in the initial uncovered state, and the second insulation quilt state judgment model outputs that the insulation quilt is in the initial uncovered state, then record the moment when the insulation quilt is in the initial uncovered state as the uncovering time of the insulation quilt;

[0119] S142. When the first insulation quilt state judgment model outputs that the insulation quilt is in the initial covered state, and the second insulation quilt state judgment model outputs that the insulation quilt is in the initial covered state, then record the moment when the insulation quilt is in the initial covered state as the covering time of the insulation quilt;

[0120] S143. Output and save the uncovering time and covering time of the insulation quilt.

[0121] Through the minute-level real-time collection of multi-source meteorological parameters (air temperature, total radiation, photosynthetically active radiation) inside and outside the greenhouse and the dual-model collaborative decision-making mechanism, the present invention completely solves the error problem caused by the traditional method of extracting the uncovering time and covering time of the thermal insulation quilt, which depends on a single parameter or manual experience. The first model constructs a state machine logic based on the minute-variation rate of total radiation and air temperature to accurately identify the critical point of uncovering and covering the thermal insulation quilt (triggering the initial uncovering state); the second model dynamically captures sudden changes in light through the minute-variation rate of photosynthetically active radiation (determining the initial uncovering state), effectively overcoming the interference of sudden sunny weather after rain. The output results of the dual models are cross-validated to reduce the misjudgment rate of the uncovering time and covering time of the thermal insulation quilt. In addition, through the full-process automated design from data collection, model calculation to decision execution, the present invention realizes the unmanned and precise management of solar greenhouses. In the technical solution, the climate observation station collects data (such as S air temperature, N radiation, PAR value) at 5-minute intervals and calculates key indicators in real time through a preset algorithm; the model decision result can directly drive the rolling machine of the thermal insulation quilt (drive the rolling machine according to the output time of the decision result to drive the thermal insulation quilt to cover or uncover) (the driving principle of the rolling machine is the prior art and will not be elaborated here) to eliminate manual operation delay.
