It has developed rapidly in northern my country, especially in North China, Northeast China, and Huanghuai region, greatly alleviating the problem of off-season vegetable supply in my country, especially in northern China. Tomato is the main vegetable crop cultivated in Banpo shed solar greenhouse, and it is also one of the fruit and vegetable crops with the largest cultivation area and the highest yield in my country. With the continuous acceleration of urbanization and aging in my country, the problem of insufficient labor supply in the tomato planting industry has become more and more prominent, and the labor cost has continued to rise, seriously affecting the sustainable development of the industry. The existence of the back wall of the Banpo shed solar greenhouse requires a certain distance between the two to reduce the impact of the front Banpo shed solar greenhouse on the daylighting rate of the rear solar greenhouse. At the same time, since the temperature of the greenhouse is mainly affected by light, in order to actively adjust the temperature of the greenhouse, the dependence on heating or cooling devices is relatively high, which increases energy consumption.

[0003] In the process of implementing the technical solution of the invention in the embodiments of the present application, the inventors of the present application found that the above-mentioned technology has at least the following technical problems: the spacing between the semi-slope greenhouses is large. The higher the dimension, the larger the spacing, resulting in a large area occupied. How to improve land utilization and increase economic output value; how to carry out automated mechanized cultivation work, reduce the number of laborers and labor intensity in production, improve production efficiency, and ensure the yield and quality of tomatoes.

[0037] In a second aspect, the present invention further proposes a facility tomato automated cultivation system, the facility comprising a greenhouse shed body, and a translucent plastic covering film and a heat-insulating quilt adapted to the greenhouse shed body to build a yin-yang greenhouse shed, the length direction of the yin-yang greenhouse shed is east-west, a plurality of columns are arranged between the sun shed and the shady shed, the sun shed and the shady shed are connected by the columns, the columns are used to support the yin-yang greenhouse shed, and a rollable ventilation and heat-insulating film is arranged between the columns, the system comprises:

[0038] A monitoring unit is used to monitor the temperature inside the sun-facing shed and the shade-facing shed respectively;

[0039] The analysis unit is used to compare the current high temperature of the sunny shed with the cultivation temperature of the plants in the sunny shed, and the current low temperature of the shady shed with the cultivation temperature of the plants in the shady shed;

[0040] The regulating unit is used to adjust the temperature inside the sun shed and the shady shed by adjusting the rolling height of the insulation film when the current temperature of the sun shed is higher than the cultivation temperature of the plants in the sun shed and the current temperature of the shady shed is lower than the cultivation temperature of the plants in the shady shed.

[0041] In a third aspect, an electronic device comprises: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor is used to implement the steps of the automated cultivation method of facility tomatoes as described in any one of the first aspects above when executing the computer program stored in the memory.

[0042] In a fourth aspect, the present invention further proposes a computer-readable storage medium having a computer program stored thereon, and when the computer program is executed by a processor, the method for automated cultivation of greenhouse tomatoes according to any one of the above items in the first aspect is implemented.

[0043] In summary, the automated cultivation method of facility tomatoes proposed in this application monitors the temperature inside the sun shed and the shade shed respectively; compares the current high temperature of the sun shed with the cultivation temperature of the plants in the sun shed, and the current low temperature of the shade shed with the cultivation temperature of the plants in the shade shed; when the current temperature of the sun shed is higher than the cultivation temperature of the plants in the sun shed and the current temperature of the shade shed is lower than the cultivation temperature of the plants in the shade shed, the temperature inside the sun shed and the shade shed is adjusted by adjusting the rolling height of the insulation film. Thus, by monitoring the temperature inside the sun shed and the shade shed respectively, and comparing the difference between each and the plant cultivation temperature, the situation where the temperature of the sun shed is too high and the temperature of the shade shed is too low can be accurately identified. This precise monitoring and comparison mechanism enables the greenhouse to adjust the temperature in a timely and effective manner to ensure that the crops are in the best growth environment. When the temperature of the sun shed is too high and the temperature of the shade shed is low, the air flow and heat exchange between the two sheds are promoted by adjusting the rolling height of the insulation film, so that the excess heat of the sun shed can be transferred to the shade shed. This method can balance the temperature distribution in the greenhouse, avoid overheating of the sunny shed and overcooling of the shady shed, and improve the heat utilization efficiency of the entire greenhouse. By utilizing natural heat exchange instead of relying on additional heating or cooling equipment, the greenhouse can reduce energy consumption while maintaining a suitable temperature. This method not only reduces the operating cost of the greenhouse, but also meets the requirements of energy conservation and environmental protection. Temperature is one of the important factors affecting the growth of vegetables. Through precise temperature control, ensuring that both the sunny shed and the shady shed are within the appropriate cultivation temperature range, it can promote the healthy growth of crops and improve the quality and yield of crops.

[0044] Enhance the adaptability of the greenhouse system: This method enables the greenhouse to dynamically respond to changes in the external environment (such as sunlight intensity and external temperature changes) by adjusting the rolling height of the insulation film in real time, thereby improving the adaptability and flexibility of the system and ensuring a stable cultivation environment under various weather conditions.

[0045] The automated cultivation method for facility tomatoes of the present invention, and other advantages, objectives and features of the present invention will be partially reflected through the following description, and will also be partially understood by those skilled in the art through research and practice of the present invention.

[0057] To solve the problem that the temperature in the greenhouse is greatly affected by sunlight and has a high dependence on the heating and cooling systems, please refer to Figure 1 , which is a flow chart of an automated cultivation method for facility tomatoes provided in an embodiment of the present application, wherein the facility comprises a greenhouse main body, and a yin-yang greenhouse constructed with a light-transmitting plastic covering film and a heat-insulating quilt adapted to the greenhouse main body, wherein the length direction of the yin-yang greenhouse is east-west, and a plurality of columns are arranged between the sun-side shed and the shady-side shed, and the sun-side shed and the shady-side shed are connected by the columns, and the columns are used to support the yin-yang greenhouse, and a rollable ventilation and heat-insulating film is arranged between the columns, and the method may specifically include: steps S110 to S130.

[0058] S110, monitoring the temperature inside the sun-facing shed and the shade-facing shed respectively.

[0059] S120, respectively comparing the current high temperature of the sunny shed with the cultivation temperature of the plants in the sunny shed, and the current low temperature of the shady shed with the cultivation temperature of the plants in the shady shed.

[0060] S130, when the current temperature of the sunny shed is higher than the cultivation temperature of the plants in the sunny shed and the current temperature of the shady shed is lower than the cultivation temperature of the plants in the shady shed, adjust the temperature inside the sunny shed and the shady shed by adjusting the rolling height of the insulation film.

[0061] In some embodiments, the greenhouse is constructed by a yin-yang greenhouse including a greenhouse shed body, a light-transmitting plastic covering film and a heat-insulating quilt adapted to the greenhouse shed body, wherein the length direction of the yin-yang greenhouse is east-west, and a plurality of columns 3 are arranged between the sun shed 1 and the shade shed 2, and the sun shed 1 and the shade shed 2 are connected by the columns 3, and the columns 3 are used to support the yin-yang greenhouse, and a rollable ventilation and heat-insulating film is arranged on the columns for ventilation or heat preservation between the sun shed and the shade shed;

[0062] Exemplarily, the greenhouse body includes a sun shed body and a shade shed body, and the total span of the sun shed and the shade shed is 17m, of which the span of the sun shed is 10m, the span of the shade shed is 6.5m, the top height of the sun shed is 5.15m, the top height of the shade shed is 4.15m, the height of the columns is 4.15m, and the shade shed top is the same height as the columns. The main body of the sun-facing shed includes a first arch rod, a first pull rod and a first gable. The first gables on both sides are respectively located on both sides of the length of the main body of the sun-facing shed. One end of the first arch rod is installed and connected to the top of the column, and the other end is installed and connected to the foundation of the sun-facing surface of the greenhouse. Multiple first arch rods are evenly spaced to form an arch frame of the main body of the sun-facing shed. The bottom angle 4 of the sun-facing shed formed by the first arch rod and the ground can be 70 to 80 degrees. In this embodiment, it is close to 75 degrees. Multiple first pull rods are transversely fixed to each first arch rod, and the multiple first pull rods are evenly distributed in parallel. The two ends of the first pull rod are respectively arranged on the first gables on both sides, and the height slope of the first gable follows the curvature of the first arch rod. Changes: The main body of the shade shed includes a second arch rod, a second tie rod and a second gable. The second gables on both sides are respectively located on both sides of the length of the main body of the shade shed. One end of the second arch rod is installed and connected to the top of the column, and the other end is installed and connected to the foundation of the shade side of the greenhouse. Multiple second arch rods are evenly spaced to form an arch frame of the main body of the shade shed. The bottom angle of the shade shed formed by the second arch rod and the ground can be 70 to 80 degrees, and this embodiment is close to 75 degrees. Multiple second tie rods are transversely fixed to each first arch rod, and multiple second tie rods are evenly distributed in parallel. The two ends of the second tie rod are respectively arranged on the second gables on both sides, and the height slope of the second gable follows the curvature change of the second arch rod. The first tie rod, the second tie rod, the first arch rod and the second arch rod are metal composite materials with strong pressure resistance and elasticity, light weight, strong, corrosion-resistant and smooth surface.

[0063] Exemplarily, the length of the yin-yang greenhouse is 60m, the thickness of the gable is 0.5m, and the gable is provided with a door. Preferably, the door is a swing door 5, 2m wide and 2.4m high, for agricultural machinery to enter and exit.

[0064] Exemplarily, the light-transmitting plastic covering film is a drip-free, fog-eliminating polyolefin film with a thickness of 0.15 mm and a width of 130 mm; the thermal insulation quilt 6 adopts a polyethylene woven outer shell with thermal insulation material sandwiched inside the outer shell for heat preservation of the greenhouse when the temperature is low.

[0065] Exemplarily, the roof of the sun-side shed near the shady shed is convex and has a rear slope, and the roof of the sun-side shed is connected to the pillars through the rear slope to form an inclined surface. The setting of the inclined surface improves the wind resistance and pressure resistance of the light-transmitting and heat-insulating material of the sun-side shed above the pillars, and enhances the stability of the sun-side shed; the roof of the sun-side shed near the sun-side shed is perpendicular to and connected to the pillars, which is conducive to the rolling up and laying down of the thermal insulation quilt, and is conducive to the discharge of rain and snow water from the roof.

[0066] Exemplarily, the shady shed and the sunny shed are connected by a plurality of columns, the columns are evenly spaced, and the plurality of columns are arranged in a row, and the direction of the row is east-west; the columns are provided with a ventilation and thermal insulation film, which can be rolled up or cover the columns. When the shady shed and the sunny shed need to be ventilated with the outside world, the ventilation and thermal insulation film is rolled up. When the shady shed or the sunny shed needs to be ventilated separately, the ventilation and thermal insulation film covers the columns, and the film rolling machine at the bottom and / or top of the shady shed or the sunny shed is turned on. At the same time, the ventilation and thermal insulation film also plays a role in heat preservation for the shady shed and the sunny shed. In another embodiment, according to the light requirements of the vegetables in the shady shed, a light-transmitting material of the ventilation and thermal insulation film is selected to meet the light requirements of the shade-loving vegetables; the rolling up and laying down of the ventilation and thermal insulation film can be achieved manually or by installing an automatic film rolling machine.

[0067] For example, in order to achieve ventilation between the yin-yang greenhouse and the outside world, automatic film rolling machines are respectively provided at the bottom and top of the shady shed and the sunny shed.

[0068] According to some embodiments, further comprising:

[0069] Initialize the insulation film rolling height H value, starting from a smaller rolling height;

[0070] Calculate the current temperature changes of the sun-facing shed and the shade-facing shed;

[0071] Evaluate the temperature error E y and E i , if the temperature error decreases, continue to increase H until the optimal solution is found. If the temperature error increases, reduce H and try to find the optimal balance point until the minimum temperature error or the set tolerance range is reached.

[0072] In some examples, this also includes:

[0073] The rolling height of the insulation film is calculated by the following formula:

[0074] In the time step Δt, the heat Q transferred from the sun shed to the shade shed can be expressed as:

[0075]

[0076] The temperature change of the sun shed can be expressed as:

[0077]

[0078] The temperature change of the shade shed can be expressed as:

[0079]

[0080] Temperature error calculation:

[0081]

[0082]

[0083] Through the gradient descent method, H is gradually adjusted according to the temperature error feedback to minimize the objective function F(H) and minimize the total temperature error:

[0084] Minimize F(H)=E y +E i

[0085] Among them, T y is the current temperature of the sun shed, is the target temperature of the sun shed, T i is the current temperature of the shaded shed, is the target temperature of the shaded shed, A y is the area of ​​the sun shed, A i is the area of ​​the shaded shed, H is the height of the insulation film when rolled up (m) max is the maximum rolling height of the insulation film, k is the heat transfer coefficient of the insulation film, C y is the heat capacity of the sun shed, C i is the heat capacity of the shaded shed, Δt is the time step, A=min(A y ,A i ) is the minimum effective area of ​​the two sheds, used to calculate heat exchange.

[0086] In some examples, the method further includes:

[0087] Use Bayesian optimization algorithm to optimize the objective function F(H) = E y +E i .

[0088] Exemplarily, Bayesian optimization can learn from historical data and intelligently select the insulation film height H for the next test in each iteration, thereby finding the optimal solution more quickly and accurately than the gradient descent method.

[0089] It is understandable that the temperature regulation only considers the height of the insulation film, without comprehensively considering the impact of multiple variables such as humidity, wind speed, external weather changes, and crop growth stage on the greenhouse environment. This may lead to insufficient regulation accuracy. In addition, the original method uses a linear formula to approximate the heat exchange process, ignoring the nonlinear characteristics in temperature regulation, such as the complexity of air convection and the uneven temperature distribution in different areas of the greenhouse. This approximation may lead to unsatisfactory predicted temperature regulation effects.

[0090] In order to solve the above problems, in some examples, the following is also included:

[0091] The wind volume is generated at the rolling position of the thermal insulation film to increase the rolling height of the thermal insulation film and adjust the adjustment speed of the temperature inside the sun-facing shed and the shade-facing shed.

[0092] In some examples, the step of creating air volume at the rolling-up position of the thermal insulation film to increase the rolling-up height of the thermal insulation film and adjust the adjustment speed of the temperature inside the sun-facing shed and the shade-facing shed includes:

[0093]

[0094] Among them, H is the height of the insulation film, V is the wind speed at the vent, E(t) is the energy consumption, and α, β, and γ are weight coefficients used to balance temperature control and energy consumption;

[0095] Randomly initialize a set of parameter combinations, calculate the objective function value corresponding to each parameter combination, select the parameter combination with better performance as the basis for the next generation according to the evaluation results, generate a new generation of parameter combinations through crossover and mutation operations, repeat the above steps, improve the parameter combination generation by generation, approach the optimal solution, reach the preset objective function value threshold, or reach the maximum number of iterations.

[0096] In some examples, this also includes:

[0097] The parameter combination of each particle is adjusted according to the global optimal and local optimal positions instead of generating a new generation of parameter combinations through crossover and mutation operations.

[0098] Exemplarily, nonlinear optimization algorithms (such as genetic algorithms, particle swarm optimization, etc.) are used to more accurately model and control the complex heat exchange process in the greenhouse, and the control strategy is dynamically adjusted in combination with a real-time feedback system. Genetic algorithms simulate the natural selection process and solve optimization problems through operations such as genetic variation, crossover and selection. It is suitable for high-dimensional, nonlinear and multi-peak optimization problems. It is suitable for optimizing the height of the insulation film, ventilation parameters and thermal management strategies of the greenhouse to minimize temperature deviation, energy consumption and meet the needs of crop growth. Particle swarm optimization simulates the group behavior of flocks of birds or fish, and gradually approaches the global optimal solution through information sharing between individual particles. It is suitable for nonlinear optimization problems in continuous space. In greenhouse control, PSO can be used to optimize temperature adjustment parameters (such as insulation film height, wind speed control) to adapt to dynamic environmental changes. By adopting a combination strategy of nonlinear optimization and real-time feedback control, the regulation of the greenhouse environment will be more refined and intelligent, effectively improving the efficiency and benefits of agricultural production.

Appropriate ventilation can be carried out according to weather conditions and the yin and yang conditions of the greenhouse.

[0156] (3) Flowering and fruiting period

[0157] In a specific embodiment, the amount of watering is moderate, so that the soil is moist, the water content is 35%, and watering is done twice a week. The watering frequency can be adjusted according to the weather, soil moisture and plant growth conditions; water-soluble compound fertilizer containing phosphorus and potassium elements is applied from the beginning of budding to before flowering to promote flower bud differentiation and fruit development, and fertilizer is applied every 12 days, with 15 kilograms per mu each time. The daytime temperature is controlled at 20 to 27 degrees, and the nighttime temperature is controlled at 14 to 17 degrees. The size of the vent is reasonably adjusted according to the weather and the yin and yang conditions of the greenhouse.

[0158] (4) Resulting period

[0159] In a specific embodiment, the amount of watering is moderate to make the soil moist with a water content of 40%. Watering is done once a week, and the frequency of watering can be adjusted according to the weather, soil moisture and plant growth. Phosphorus and potassium fertilizers are applied once every 10 days, with 4.8 kg of diammonium phosphate fertilizer and 3.5 kg of potassium sulfate fertilizer applied per mu. The amount of phosphorus and potassium fertilizers applied is appropriately adjusted according to the soil and plant results. The daytime temperature is controlled at 24 to 27 degrees, and the nighttime temperature is controlled at 12 to 16 degrees. The size of the vents is reasonably adjusted according to the weather and the yin and yang conditions of the greenhouse.

After the plants are planted, water is poured thoroughly on the substrate and surrounding soil around which the roots of the plants are entangled, so that the roots are in close contact with the mud. The seedling-acclimatization period begins after 6 days. During the seedling-acclimatization period, water is properly controlled to promote the roots to grow downward. Water is applied in the morning every 3 days. The amount of water should not be too large, so that the soil is moist with a moisture content of 68%. 0.8 kg of microbial agent per mu is configured in the first seedling-acclimatization water. The microbial agent enables the beneficial bacteria in the roots of tomatoes to actively exert their advantages in niche competition, thereby protecting the roots from infection by harmful bacteria, thereby promoting the healthy growth of tomato plants.

[0188] In a specific embodiment, the daytime temperature is controlled at 23-28 degrees, and the nighttime temperature is controlled at 15-18 degrees.

For example, the ventilation and insulation film between the shade and sun sheds is rolled up, and a film rolling machine rolls up the covering film of the sun shed and another film rolling machine rolls up the covering film of the shade shed to ventilate the entire shade and sun greenhouse. Alternatively, the ventilation and insulation film on the columns between the shade shed and the sun shed is covered on the columns, that is, in an unrolled state, and the shade and sun sheds are ventilated separately. In the above situations, the size of the vents can be adjusted appropriately.

[0190] (2) Seedling growth period

[0191] In a specific embodiment, the tomato seedlings enter the seedling growth period 8 days after being planted and the seedlings begin to bud. When the soil is dry, water is applied appropriately so that the soil moisture content is 52%. The daytime temperature is controlled at 20 to 28 degrees, and the nighttime temperature is 13 to 18 degrees. Appropriate ventilation can be carried out according to weather conditions and the yin and yang conditions of the greenhouse.

[0192] (3) Flowering and fruiting period

[0193] In a specific embodiment, the amount of watering is moderate, so that the soil is moist, the water content is 40%, and watering is done twice a week. The watering frequency can be adjusted according to the weather, soil moisture and plant growth conditions; water-soluble compound fertilizer containing phosphorus and potassium elements is applied from the beginning of budding to before flowering to promote flower bud differentiation and fruit development, and fertilizer is applied every 10 days, with 14.5 kg per mu of fertilizer each time. The daytime temperature is controlled at 20 to 27 degrees, and the nighttime temperature is controlled at 14 to 17 degrees. The size of the vents is reasonably adjusted according to the weather and the yin and yang conditions of the greenhouse.

[0194] (4) Resulting period

[0195] In a specific embodiment, the amount of watering is moderate to make the soil moist with a water content of 35%. Watering is done once a week, and the frequency of watering can be adjusted according to the weather, soil moisture and plant growth. Phosphorus and potassium fertilizers are applied once every 10 days, with 5.2 kg of diammonium phosphate fertilizer and 4.8 kg of potassium sulfate fertilizer applied per mu. The amount of phosphorus and potassium fertilizers applied is appropriately adjusted according to the soil and plant results. The daytime temperature is controlled at 24 to 27 degrees, and the nighttime temperature is controlled at 13 to 17 degrees. The size of the vents is reasonably adjusted according to the weather and the yin and yang conditions of the greenhouse.

[0196] S6: Configure a mobile platform for high-seedling operations to assist manual management of tomato seedlings, including pruning, forking, vine hanging, and fruit picking.

[0197] Embodiment 3

[0198] The parameters and planting methods of Example 3 are basically the same as those of Example 1, except that in Example 3, tomatoes are planted in a yin-yang greenhouse with high fertility soil. When applying base fertilizer, the amount of organic fertilizer applied per mu of high fertility soil is 0.5 to 1.0 tons, and the amount of compound fertilizer applied per mu is 0 to 15 kilograms. Preferably, the amount of organic fertilizer applied in this embodiment is 0.6 tons, and the amount of compound fertilizer applied is 5 kilograms.

[0199] The judgment criteria for soil fertility in Examples 1, 2 and 3 of the present application are based on the soil nutrient classification standards of Beijing.

[0200] The three embodiments provided in this application differ in that the data in the embodiments are adjusted, the production efficiency of the three embodiments is the same, and the tomato yield and quality are also almost the same.

[0201] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0202] (1) A fertilizer spreader is used to apply fertilizer, a rotary tiller is used to till or deep plow the soil, an integrated ridging and film covering machine is used to ridge, lay drip irrigation pipes and lay ground film, and an automatic fruit and vegetable transplanter is used to transplant tomato seedlings. A high-vine plant is managed through a high-seedling operation mobile platform, which effectively solves the technical problem of relying on manual labor and low production efficiency in the existing technology in tomato planting and management, thereby achieving the technical effect of full mechanization of tomato operation management, reducing labor costs, and greatly improving labor and production efficiency.

[0203] (2) The height and width of the greenhouse, the height of the gable and the size of the gable door, the ridge spacing, ridge-ditch spacing, bed width, plant spacing, row spacing, and the ridge spacing, ridge-ditch spacing, bed width, plant spacing, row spacing, watering, fertilization, ventilation and temperature that affect the yield and quality of tomatoes were designed to coordinate with the mechanical facilities. This effectively solved the problem of low mechanization level in the existing technology, thereby realizing the integration of agricultural machinery and agronomy, improving the degree of mechanical automation and production efficiency, and ensuring the technical effect of tomato yield and quality.

[0204] (3) The yin-yang greenhouse structure is adopted to make full use of the shadow area caused by the half-slope greenhouse sunroom. A shade shed is attached to the north side of the original wall. At the same time, the wall is removed and multiple columns are set between the shade shed and the sun shed. The columns are provided with ventilation and heat preservation film. This effectively solves the technical problem of low land utilization rate of the existing half-slope greenhouse. It also realizes staggered planting, staggered market launch or planting of shade-loving vegetables in the shade shed, which greatly improves land utilization efficiency and the economic value of greenhouse output. In addition, the overall cost of the greenhouse is low. The shade shed can reduce the heat loss of the north wall of the sun shed and save energy.

[0205] (4) The shady shed and the sun-side shed are connected by a plurality of columns, which are evenly spaced and arranged in rows in an east-west direction; a ventilation and thermal insulation film is provided on the columns, which can be rolled up or covered. When the shady shed and the sun-side shed need to be ventilated to the outside, the ventilation and thermal insulation film is rolled up; when the shady shed or the sun-side shed needs to be ventilated separately, the ventilation and thermal insulation film covers the columns. At the same time, the ventilation and thermal insulation film also plays a role in heat preservation for the shady shed and the sun-side shed.

[0206] (5) The roof of the sun-side shed near the shady shed is convex and has a rear slope. The sun-side shed roof is connected to the pillars through the rear slope to form an inclined surface. The setting of the inclined surface improves the wind resistance and pressure resistance of the light-transmitting and heat-insulating material above the pillars of the sun-side shed, and enhances the stability of the sun-side shed; the roof of the sun-side shed near the sun-side shed is perpendicular to and connected to the pillars, which is conducive to the rolling up and laying down of the heat-insulating quilt and the discharge of rain and snow water from the roof.

[0207] In order to improve the efficiency of greenhouse mechanization, a simple mobile platform for arranging tall rice seedlings can also be installed in the greenhouse. As long as the vehicle movement and parking state can be controlled manually or intelligently, so that personnel can use the mobile platform to perform operations such as arranging tall rice seedlings, the mobile platform can be applied to this solution, and the specific structure of the mobile platform is not limited here.

[0208] In some examples, with the help of the mobile platform for arranging high-seedling crops, the above-mentioned automated cultivation method for greenhouse tomatoes may also include:

[0209] The action status data of the staff on the mobile platform is obtained, and when the matching degree between the action status data and the standard state of pruning, forking or hanging vines is greater than a preset matching degree, the state of the mobile platform is maintained in a parked state.

[0210] It is understandable that the core principle of this solution is based on the combination of motion recognition technology and automatic control technology. Its basic process includes: Motion recognition: obtain the motion data of the staff on the mobile platform through sensors (such as cameras, accelerometers or force sensors), such as the movement trajectory of the arm, angle changes, force changes, etc. Motion matching calculation: compare the motion data collected in real time with the preset standard operations (pruning, forking, hanging vines, etc.). This standard state can be set manually by experts or defined based on a model trained with historical data. Control the platform's parked state: When the system detects that the match between the staff's actions and standard operations exceeds a certain threshold, it is considered that the staff is performing effective operations. At this time, the mobile platform is kept in a parked state so that the staff can complete the work smoothly. Once the matching degree decreases (such as the operation is completed), the platform resumes the mobile state.

[0211] Specifically, for the configuration of the motion recognition system:

[0212] Sensor placement: Multiple sensors can be installed on the mobile platform to capture the worker's motion status. Commonly used sensors include:

[0213] Image sensor: monitors hand and body movements in the work area. For example, monitors arm position when pruning or the specific operation details when making a cross.

[0214] Accelerometer: Worn on the worker's arm or tool to monitor movement speed, frequency and angle changes.

[0215] Force sensor: Installed on the work tool, it monitors the force applied to ensure that standard forces are met for operations such as pruning or forking.

[0216] For the implementation of action matching:

[0217] Establishment of preset standards: Through multiple tests and expert experience accumulation, the "standard actions" for pruning, forking, vine hanging and other operations are determined in advance, including factors such as hand movement trajectory, applied force, action angle and operation duration. These standards can be stored in the system's database for real-time comparison.

[0218] Real-time comparison and feedback: The system collects the worker's action data in real time and uses algorithms to calculate its matching degree with the standard action. For example, when pruning, the system compares the degree of overlap between the actual hand movement trajectory and the standard trajectory. If the matching degree is greater than the preset threshold (e.g. 90%), it is considered that a valid operation is being performed.

[0219] For automatic control of mobile platforms:

[0220] Platform parking control: When the matching degree exceeds the preset value, the system instructs the platform to remain parked until the operation is completed. Once the action matching degree decreases (such as the operation is completed or the action stops), the system instructs the platform to resume moving.

[0221] Intelligent scheduling: If there are multiple workers working in the same greenhouse, each mobile platform can be independently controlled according to the individual operation situation. If all workers complete the operation, the platforms will resume mobile status at the same time.

[0222] Therefore, through the above principles and implementation methods, the mobile platform can automatically stop according to the real-time status of the operation, reducing the need for frequent manual operation of the platform. The staff does not need to manually control the movement and stop of the platform, and can focus on the sorting operation of high-seedling crops. This will greatly improve work efficiency. Through the precise data collection of various sensors (such as cameras, accelerometers, etc.), and comparison with standard operations, the system can accurately identify the operation status, ensure that the platform stops at the required time point, and avoid misjudgment. In particular, the sorting of high-seedling crops requires staff to frequently operate pedals or buttons to control the mobile platform. This solution greatly reduces the frequency of manual intervention through automated identification and control, allowing staff to focus on core operations and reduce physical exertion. In the process of sorting high-seedling crops, improper actions may cause damage to the plants. Through the judgment of real-time action matching, the system can prompt the staff and correct them in time when the operation does not meet the standards. This function can reduce the probability of misoperation and improve the quality of crop sorting.

[0223] For example, a worker stands on a mobile platform and prepares to prune tomatoes. The system monitors through the camera that his hand movements are highly matched with the standard pruning trajectory (for example, the matching degree reaches 95%). At this time, the system instructs the mobile platform to stop until the pruning is completed. After the pruning is completed, the hand movement stops, the matching degree decreases, and the platform restarts and moves to the next tomato. When the worker performs the cross operation, the acceleration sensor detects that the speed and strength of his arm movement meet the cross standard, and the system keeps the platform stationary. If it is detected that the worker's cross action does not meet the standard (for example, insufficient strength), the system will remind the operator to adjust the action through the prompter to ensure the quality of the operation. By introducing motion recognition and automatic control, the mobile platform for high-stalk crop sorting can greatly improve efficiency, reduce manual intervention and labor intensity in the automated cultivation of facility tomatoes, and at the same time improve the accuracy of crop management. This solution is not only applicable to tomato cultivation, but can also be extended to the management scenarios of other high-stalk crops to achieve further improvement in agricultural mechanization and intelligence.

[0224] For example, if there are multiple mobile platforms in the greenhouse, the system can coordinate control based on the status of each platform to ensure that there is no congestion caused by multiple platforms moving in the same area. At the same time, when all operations in a certain area are completed, the system can dispatch the platforms to the next area.

[0225] In some examples, such as Figures 1c to 1eThe greenhouse is equipped with a simple mobile platform for arranging tall vine crops. Elevation diagram, where 10 is the platform frame for workers to operate, 11 is the operating lever, 12 is the small pulley, 13 is the lifting frame, 14 is the front wheel, and 15 is the rear wheel. In the process of tomato planting, manual pruning, forking, vine hanging and other plant management are required. The greenhouse is equipped with a simple mobile platform for arranging tall vine crops to assist workers in plant management. When workers perform pruning, forking, vine hanging and other operations, they pull the operating lever 11 to change the crop arranging platform mode to a fixed state (such as Figure 1e ), that is, the operating rod 11 pulls the small pulley 12, and the small pulley drives the lifting frame 13 to retract the front wheel 14 and the rear wheel 15 of the simple high seedling crop sorting platform, and the frame 10 of the crop platform falls to the ground, making the working platform more stable and convenient for the staff to manage the plants. When it is necessary to move forward, push the operating rod 11 to change the crop platform mode to the mobile state (such as Figure 1d ), that is, pushing the operating rod 11 to push the small pulley 12 down, the small pulley pushes the lifting frame 13, the front wheels 14 and the rear wheels 15 of the simple high-seedling crop sorting platform are lowered, and the simple high-seedling crop platform is pushed forward. This can effectively solve the problem of high-intensity handling operations caused by the long length of the greenhouse and the lack of suitable logistics equipment, improve the work efficiency of workers, and reduce labor intensity.
