[0049] See also Figure 1-Figure 7 As shown, an embodiment of the present invention provides a mobile leafy vegetable cultivation system, comprising:

[0050] A traction-type cultivation module, which is used to automatically plant leafy vegetables and transport the leafy vegetables from the planting end to the harvesting end within a set growth cycle, comprises a traction-type track transmission mechanism arranged between the planting end and the harvesting end, a cultivation trough arranged on the traction-type track for fixing the leafy vegetables, and a plurality of planting cups placed in the planting holes of the cultivation trough for planting the leafy vegetables;

[0051] A cultivation trough transport module, which is connected to the traction-type cultivation module and is used to place / remove a single cultivation trough on the traction-type track conveying mechanism, and to transport the cultivation trough between the planting end and the harvesting end of the traction-type track conveying mechanism;

[0052] A cultivation tank cleaning module, which is connected to the cultivation tank transport module and is used to clean the cultivation tank after harvesting;

[0053] A water and fertilizer supply module, which is connected to the traction-type cultivation module and is used to supply water and fertilizer to each cultivation tank;

[0054] The mobile cultivation control module is respectively connected to the traction cultivation module, the cultivation trough transport module and the water and fertilizer supply module, and is used to determine the cultivation trough traction speed of the traction track transmission mechanism according to the leafy vegetable growth data, and to determine the water circulation speed according to the utilization of water and fertilizer in each cultivation trough.

[0055] The present invention uses a traction-type mobile transmission for the seedling bed of leafy vegetables, and can automatically harvest the leafy vegetables at the harvesting end according to the growth cycle of the leafy vegetables, thereby avoiding manual transportation and improving the degree of automation of cultivation. In addition, by adopting a cultivation trough transportation module to transport the cultivation trough between the planting end and the harvesting end, the cultivation trough can be utilized to the greatest extent, thereby improving the production efficiency of the cultivation system and further improving the degree of automation of the cultivation system.

[0056] Specifically, the traction type track transmission mechanism includes:

[0057] A seedbed steel frame 1, which is used to carry the cultivation trough;

[0058] The traction track is arranged on the seedling bed steel frame, and includes a plurality of ratchet-type traction chains 2 arranged in parallel on the upper surface of the seedling bed steel frame, a rotating assembly 3 for driving the traction chain to rotate, and a driving motor 4 for driving the rotating assembly to move.

[0059] It can be understood that in the cultivation room, the number of the traction-type track transmission mechanisms can be several, which can be arranged on the same plane or arranged in parallel along the height direction. No specific restrictions on the number and form are made here. Technical personnel in this field can make adaptive layouts according to actual cultivation scenarios. As long as the corresponding functions can be achieved, they will not be elaborated here.

[0060] Specifically, the cultivation trough transport module includes:

[0061] A gantry type movable frame 5, which is arranged above the steel frame of the seedbed and parallel to the cultivation trough, so as to move between the planting end and the harvesting end of the cultivation trough;

[0062] Moving rails 6, which are arranged at both ends of the gantry-type moving frame in contact with the steel frame of the seedling bed, and are used to guide the moving path of the gantry-type moving frame;

[0063] The transport motor 7 is arranged on the gantry type moving frame, and is used to drive the rotating wheels at both ends of the gantry type moving frame to move so that the gantry type moving frame 5 moves on the moving track 6 .

[0064] Specifically, the cultivation trough is a rectangular box-shaped hollow structure 7, a top surface of which is provided with a plurality of through planting holes for placing planting cups, and a bottom thereof is provided with a positioning clamping portion for cooperating with the ratchet-type traction chain to form a fixed connection with the ratchet-type traction chain.

[0065] It is understandable that the present invention does not limit the specific implementation structure of the pawl and the positioning clamping portion, as long as it can enable the pawl and the positioning clamping portion to cooperate to form a detachable fixed connection, and no specific limitation is made here.

[0066] Specifically, the water and fertilizer supply module identifies changes in the level of the water and fertilizer in the cultivation tank after the planting cup is placed and changes in the fertilizer content in the water.

[0067] In implementation, the water-fertilizer supply module may include a liquid level meter and an element content detector. The liquid level meter is used to detect the liquid level of the water-liquid fertilizer in the cultivation trough, and the element content detector is used to detect the fertilizer content in the water-liquid. Through continuous detection, the changes in the liquid level of the water-liquid fertilizer and the changes in the fertilizer content in the water-liquid can be obtained.

[0068] Specifically, the water and fertilizer supply module includes:

[0069] The liquid level sensor is arranged in each cultivation trough to identify the liquid level of the water fertilizer in the cultivation trough; preferably, it can be a liquid level meter.

[0070] A water and fertilizer supply tank, which is used to store liquid fertilizer;

[0071] A liquid supply pump connected to the water-fertilizer supply tank and each of the cultivation tanks, for pumping water-liquid fertilizer into each of the cultivation tanks;

[0072] The recovery tank is connected to each of the cultivation tanks and is used to store the water circulating back in the cultivation tank.

[0073] It can be understood that the liquid supply pump is used to pump the liquid fertilizer in the water and fertilizer supply tank into the cultivation tank, so that the bottom of the planting cup contacts the liquid fertilizer, and the leafy vegetables absorb the water and nutrients in the liquid fertilizer. When the nutrient elements are too low, new liquid fertilizer is continuously extracted through the liquid supply pump for replenishment, replacing the old liquid with too low nutrient elements and recovering it to the recovery tank for storage.

[0074] In another embodiment, the mobile leafy vegetable cultivation system further comprises:

[0075] A visual recognition module connected to the cultivation trough transport module, for determining the location information of the cultivation trough and the first cleanliness of the appearance of the cultivation trough according to the acquired image information of the cultivation trough;

[0076] A cleaning data recognition module, which is connected to the visual recognition module and is used to determine the second cleanliness of the cultivation trough according to the weight data of the cultivation trough;

[0077] A mobile control module is respectively connected to the cultivation trough transport module and the cultivation trough cleaning module, and is used to determine whether the cleanliness of the cultivation trough meets the transportation standard according to the first cleanliness and the second cleanliness, and to determine the transportation position of the cultivation trough based on the judgment result of the transportation standard.

[0078] Specifically, the position information of the cultivation trough is used to locate the current position of the cultivation trough, which can determine the three-dimensional size and specific position data of the cultivation trough by image acquisition, so that the cultivation trough transportation module can obtain the accurate position of each cultivation trough.

[0079] It can be understood that the first cleanliness is determined based on the image features in the image of the inner wall of the cultivation trough collected by the visual recognition module. It can be understood that the area of ​​the residue in the image of the inner wall of the cultivation trough can be obtained by training the image data, and the first cleanliness of the cultivation trough is determined by the ratio of the area of ​​the residue on the inner wall of the cultivation trough after cleaning to the area of ​​the inner wall in the image, that is, the first cleanliness is the ratio of the area of ​​the residue to the area of ​​the inner wall in the image, and the first cleanliness is less than or equal to 1.

[0080] Specifically, a weight detector may be provided in the cleaning data identification module, and the second cleanliness level is the ratio of the initial weight of each cultivation trough to the actual weight after cleaning, and the second cleanliness level is less than or equal to 1.

[0081] In implementation, the mobile control module determines and calculates a cleaning characteristic value according to the first cleanliness and the second cleanliness, and compares the cleaning characteristic value with a preset threshold value, and determines whether the cleanliness of the cultivation tank meets the transportation standard according to the comparison result;

[0082] Specifically, the cleaning characteristic value is the product of the first cleanliness and the second cleanliness, and the preset threshold is set according to actual needs. Usually, the preset threshold is set to 0.8-0.9, and preferably, the preset threshold is set to 0.85;

[0083] If the cleaning characteristic value is less than the preset threshold, it is determined that the cleaning of the cultivation trough does not meet the transportation standard and needs to be cleaned again. At this time, the cultivation trough cleaning module can select a larger cleaning parameter to clean the cultivation trough again.

[0084] If the cleaning characteristic value is greater than or equal to the preset threshold, it is determined that the cleanliness of the cultivation trough meets the transportation standards. The cultivation trough transport module can be controlled to transport the cultivation trough to the planting end and placed at the corresponding ratchet position for positioning and installation through visual recognition.

[0085] In another embodiment, the mobile leafy vegetable cultivation system further comprises:

[0086] A growth detection module, which is connected to the cultivation tank transport module and is used to obtain images of leafy vegetables on the planting cups to determine growth data of the leafy vegetables, wherein the growth data includes growth height, growth speed and health status of the leafy vegetables;

[0087] The mobile cultivation control module is also used to adjust the circulation speed of the liquid water fertilizer based on the growth data.

[0088] Specifically, the mobile cultivation control module determines whether to adjust the circulation speed of the water and fertilizer according to the consistency of the growth speed of the leafy vegetables in each cultivation tank within a preset period;

[0089] If the growth rates of the leafy vegetables in each cultivation tank are in line with or higher than the corresponding growth range, it is determined that there is no need to adjust the circulation rate of the liquid fertilizer, and the liquid fertilizer is pumped at the current liquid supply rate;

[0090] If the growth rate of the leafy vegetables in each cultivation trough is lower than the corresponding growth range, it is determined that the circulation rate of the liquid water fertilizer needs to be adjusted, and the current liquid supply rate is increased to pump the liquid water fertilizer.

[0091] In another implementation, the health status of the leafy vegetables can be determined according to the area of ​​the characteristic region in the image of the leafy vegetables, and the circulation speed of the water-liquid fertilizer can be adjusted according to the health status;

[0092] The characteristic areas include yellowed areas and insect-eaten areas. The corresponding characteristic area is obtained through image training. The health status of leafy vegetables is the ratio of the characteristic area to the image area.

[0093] If the area of ​​the characteristic region accounts for a proportion of the image area that is greater than or equal to the preset area, it is determined that the circulation speed of the water-liquid fertilizer needs to be adjusted, and the current liquid supply speed is increased to pump the water-liquid fertilizer;

[0094] If the area of ​​the feature region accounts for a smaller proportion of the image area than the preset area, it is determined that there is no need to adjust the circulation speed of the liquid fertilizer.

[0095] Specifically, the mobile cultivation control module is used to determine the growth compliance rate according to the growth rate of the leafy vegetables in each cultivation trough and the corresponding preset speed, and determine the traction speed of the cultivation trough based on the growth compliance rate.

[0096] Specifically, the ratio of the growth rate of the leafy vegetables in each cultivation trough to the preset standard rate is calculated respectively, and the growth compliance rate is calculated according to the ratio of the number of ratios greater than 0.9 in the ratios of each cultivation trough to the total number of tractions of each cultivation trough;

[0097] If the growth compliance rate is greater than or equal to the preset growth compliance rate, the traction speed of the cultivation trough does not need to be adjusted and is set at the preset traction speed;

[0098] If the growth compliance rate is less than the preset growth compliance rate, the traction speed of the cultivation trough needs to be adjusted, and the adjusted traction speed is calculated by multiplying the preset traction speed by the growth compliance rate.

[0099] It is understood that the preset traction speed is the speed at which the harvesting end can obtain leafy vegetables that meet the harvesting standards when the cultivation trough is pulled from the planting end to the harvesting end at the preset traction speed. For example, it takes 25 days for leafy vegetables to grow to meet the harvesting standards from planting, and the length of the traction track is 100 meters, then the traction speed is 100 meters / 25 days, that is, 4 meters / day.

[0100] Specifically, the mobile cultivation control module is further used to adjust the cleaning parameters of the cultivation and cleaning module according to the first cleanliness and the second cleanliness.

[0101] In an embodiment, the mobile cultivation control module is further used to calculate a cleaning characteristic value according to the first cleanliness and the second cleanliness, and adjust the cleaning parameters of the cultivation cleaning module according to the cleaning characteristic value;

[0102] Among them, the cleaning characteristic value is negatively correlated with the cleaning intensity parameter.

[0103] It is understandable that the cleaning characteristic value indicates the degree of cleanliness of the cultivation trough. The smaller the cleaning characteristic value, the poorer the degree of cleanliness of the cultivation trough. At this time, the cleaning intensity can be enhanced by increasing the flow rate of cleaning water, increasing the pressure of cleaning water flow, or increasing the brushing intensity and speed of brushing. Those skilled in the art can set it according to the actual cleaning scene, which will not be described in detail here.

[0104] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
