Description

Technical Field

[0001] The invention relates to the field of automatic control, and in particular to a control system and a control method for an agricultural planting shed. Background Art

[0002] With the continuous advancement of agricultural production technology and the growing needs of people, greenhouses (also known as agricultural planting greenhouses) are increasingly widely used in agricultural production. Greenhouses are not only widely used in the cultivation of vegetables and fruits, but also gradually expanded to the cultivation of flowers, plants and trees. The development of this technology enables people to enjoy fresh vegetables and fruits in off-season, greatly breaking the restrictions of seasons and significantly improving people's quality of life.

[0003] At present, agricultural planting has developed from traditional planting to large-scale base planting. However, the development bottleneck of large-scale base planting is high management cost. The daily management of greenhouses is cumbersome. For example, daily operations such as rolling up curtains, ventilating, temperature control, humidity control, and daylight control are required, which leads to high management costs. In addition, some existing smart greenhouses cannot realize automatic fertilization and spraying of plants, and cannot fertilize the leaves or roots of plants according to the actual needs of the plants, which may cause scalding of the leaves due to excessive fertilizer when fertilizing the leaves, causing the plants to wither, etc., and foliar fertilization cannot ensure that the fertilizer falls at the root of the plant, resulting in low fertilizer utilization rate.

[0004] Therefore, how to solve the current problem of automatically adjusting the greenhouse environmental information according to the growth needs of the plants in the greenhouse, and how to reduce management costs and management intensity, is a technical problem that technical personnel in this field urgently need to solve. Summary of the invention

DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described in detail below through specific embodiments and in combination with the accompanying drawings; it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not intended to limit the present invention in any way; the accompanying drawings in the present invention are only used to assist in the description of the embodiments and to facilitate understanding, and are not intended to limit the present invention in any way.

[0022] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification so that people familiar with this technology can understand and read them, and are not used to limit the conditions under which the present invention can be implemented. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical contents disclosed in the present invention without affecting the effects and purposes that can be achieved by the present invention.

[0023] As described in the background technology, currently the greenhouse cannot automatically adjust the temperature, humidity and light according to the growth needs of the plants, and cannot automatically fertilize or spray the roots or leaves of the plants, resulting in high management costs and great management difficulties.

[0024] Based on the above reasons, this embodiment provides a control system for an agricultural planting shed, such as Figure 1 As shown, the system includes: The acquisition module 100 is used to acquire basic information and environmental information of the plants in the planting shed in real time; The plant database 200 is used to store basic information of various plants and basic information of plants at different growth stages and environmental information required by plants at different growth stages to form original plant information; The environmental compensation module 300 automatically adjusts the real-time environmental information in the planting shed to achieve environmental compensation according to the environmental information required by the plants during the growth stage; The analysis control module 400 is used to match and compare the basic plant information obtained by the acquisition module in real time with the original plant information in the plant database, determine the growth environment information required for the basic plant information obtained in real time, and compare and analyze the required growth environment information with the environmental information obtained in real time to control the action of the environmental compensation module.

[0025] The above-mentioned technical features can obtain the basic information of plants and the environmental information in the planting shed in real time through the acquisition module, so that the analysis and control module can match and compare the various information collected by the acquisition module with all the plant information in the plant database, so as to determine whether the plants are suitable for growth in the current environment and control the action of the environmental compensation module to realize automatic adjustment of the environmental information in the shed, thereby providing a better growth environment for the plants.

[0026] Exemplarily, the acquisition module includes: A temperature sensing unit for detecting the air temperature in the growing shed; A humidity sensing unit for detecting the air humidity in the growing shed; A light sensing unit is used to detect the light intensity of sunlight in the planting shed; a distance sensing unit for detecting the growth height of plants in the growing shed, and; The image sensing unit is used to detect images of plants.

[0027] Exemplarily, the control system further includes a temporary storage module for storing plant growth information and warning information; An input and output module is used to manually store basic plant information in a plant database or a temporary storage module, and to display plant growth information and early warning information in real time, and; Power supply module, used to supply power to the entire system.

[0028] In order to solve the problem of insufficient storage capacity in the temporary storage module and the plant database, in one embodiment, a cleaning unit is provided in the plant database and the temporary storage module. The cleaning unit can automatically clean and delete the information stored in the plant database and the temporary storage module according to manually set cleaning conditions or manually clean and delete the information. The cleaning conditions include a cleaning period or basic plant information.

[0029] When a plant is planted, the basic information of the plant is stored in a temporary storage module and a plant database (if the basic information of the plant of the plant is already in the plant database, it is not necessary to store it in the plant database). When the plant grows, the temporary storage module stores the basic growth information and early warning information of the plant collected in real time. The early warning information is convenient for the staff to process in time, so as to ensure that the plant grows in a suitable environment. After the plant is harvested, the staff can clear the basic growth information and early warning information of the currently harvested plant stored in the temporary storage module through the cleaning unit. At the same time, the staff can also use the cleaning unit to clean up the plant information in the plant database that will not be planted later, so as to release space for subsequent use. The cleaning condition is to determine the longest time from the seedling to the harvest of the plant according to the growth stage information required by different plants, so as to determine the cleaning period for automatic cleaning. The plant information in the cleaning condition is based on the name of the plant to be cleaned input by the staff, and the plant information of the plant to be cleaned, the plant image information of the plant at different growth stages and the required environmental information are automatically selected and cleaned.

[0030] Exemplarily, the environmental compensation module provides temperature, humidity and light compensation in the planting shed, and can also fertilize and spray the leaves and / or roots of the plants in the planting shed.

[0031] Exemplarily, the power supply module is powered by photovoltaic power generation or agricultural electricity, and a backup power supply is provided in the power supply module.

[0032] The plant database and temporary storage module can both be configured as computer-readable storage media, the analysis and control module can be configured as a microcontroller, and the input and output module can be configured as a control panel and a display screen.

[0033] In order to implement the control system of the agricultural planting shed, in one embodiment, the agricultural planting shed is as follows: Figure 3-Figure 6As shown, it includes a scaffolding body 1 and side panels 2 and a transparent top panel 3 installed on the outside of the scaffolding body 1, photovoltaic panels 5 are installed on both sides of the top of the transparent top panel 3 through support rods 4, and the photovoltaic panels can correspond to the power supply module in the control system, and a support frame 8 is horizontally arranged above the inside of the scaffolding body 1, and an information acquisition mechanism is arranged on the support frame 8, and a sunshade 9 that can be opened and closed is arranged on the top of the support frame 8, and a spraying, fertilizing and watering mechanism and a fill light that can be automatically turned on and off are arranged at the bottom of the support frame 8 (the fill light is a conventional LED lamp, which is not shown in detail in the accompanying drawings because it is a conventional lamp tube), and a ventilation mechanism for ventilating or closing the inside of the scaffolding body 1 is also arranged on the side panel 2.

[0034] In order to solve the problem that the information acquisition mechanism is not easy to install and detect the internal plant information and the sunshade is not easy to open and close, such as Figure 7 As shown, the support frame 8 is a frame, specifically, it is formed by two support plates 81 and a connecting rod 82 arranged between the two support plates 81. The two ends of the support plate 81 are fixed on the scaffolding body 1, and an intermediate plate 83 is arranged between the two support plates 81. The intermediate plate 83 passes through the connecting rod 82 and is fixed. The information acquisition mechanism is installed on the intermediate plate 83, and a linear telescopic device 12 is arranged between the support plate 81 and the intermediate plate 83. The fixed end of the linear telescopic device 12 is installed between the support plate 81 and the intermediate plate 83, and the movable end thereof passes through the intermediate plate 83 and extends to the outside of the other support plate 81. A limiting plate 13 is arranged at the movable end of the linear telescopic device 12.

[0035] In order to solve the problem that the information acquisition mechanism is not easy to install and detect the internal plant information, such as Figure 7 As shown, the information acquisition mechanism includes a temperature sensor 14 (i.e., corresponding to the temperature sensing unit in the control system), a humidity sensor 15 (i.e., corresponding to the humidity sensing unit in the control system), a distance sensor 16 (i.e., corresponding to the distance sensing unit in the control system), an image sensor 17 (i.e., corresponding to the image sensing unit in the control system) and a light sensor 18 (i.e., corresponding to the light sensing unit in the control system). The temperature sensor 14, the humidity sensor 15, the distance sensor 16 and the image sensor 17 are all installed at the bottom of the middle plate 83 to facilitate the correspondence with the plants below, and the light sensor 18 is arranged at the top of the middle plate 83 to facilitate sunlight exposure so as to detect the light intensity.

[0036] In order to solve the problem that the sunshade is not easy to open and close automatically, such as Figure 8-Figure 11As shown, a soft connector 91 is provided at one end of the sunshade curtain 9, and the connector 91 is sleeved on the outside of the telescopic end of the linear telescopic device 12 and is fixed by a limit plate 13. The other end of the sunshade curtain 9 is wrapped around the outer end of the rotating rod 19, and the rotating rod 19 is arranged above the support plate 81 and rotatably installed between the two side plates 2 and is driven to rotate by the driving motor 10 outside the side plates 2.

[0037] In order to solve the problem that the ventilation mechanism is not easy to automatically control to achieve ventilation and closing, such as Figure 12-16 As shown, the side panel 2 is provided with a vent and an outer frame 6 is installed on the outside of the vent, a fan 7 is arranged at the position corresponding to the vent of the outer frame 6, a wind shield 20 is rotatably arranged in the middle position of the vent, and an electronic push rod 22 is arranged between the outer bottom side of the wind shield 20 and the side panel 2. When the electronic push rod 22 is retracted, the wind shield 20 is pulled to rotate to open the vent, and when the electronic push rod 22 is extended, the wind shield 20 is pushed to rotate to close the vent, thereby realizing automatic control of the ventilation mechanism to achieve ventilation and closing, and a battery 21 is also arranged inside the outer frame 6. The battery 21 can be used to store the electricity generated by the photovoltaic panel 5 under sunlight, and can also be charged by external agricultural electricity (wire outlet holes can be opened on the side and top of the outer frame to facilitate the connection of external lines with external agricultural electricity and photovoltaic panel 5). The battery corresponds to the backup power supply in the control system.

[0038] In order to solve the problem of not being able to evenly spray, fertilize and water the plants in the greenhouse, Fig.17 The spraying fertilization and irrigation mechanism includes a liquid inlet component 11 and several spray components. The liquid inlet component 11 includes a main pipeline 111 and several branch pipelines 114. The main pipeline 111 is in a rectangular frame shape and is fixed to the bottom of the support frame 8. Several branch pipelines 114 are arranged in parallel inside the main pipeline 111 and connected thereto. Several drainage ports are evenly opened at the bottom of the branch pipeline 114. Two liquid inlet pipes 112 are arranged on the outer sides of both ends of the main pipeline 111. An electrically controllable liquid inlet valve 113 is arranged on the liquid inlet pipe 112. Several spray components are connected to the bottom drainage port of the branch pipeline 114 (for the convenience of display in the drawings, only some spray components are shown). The two liquid inlet pipes 112 on the main pipeline 111, one of the liquid inlet pipes 112 is connected to an external water source, and the other liquid inlet pipe 112 is connected to an external mixing barrel, which is convenient for mixing fertilizer or liquid medicine.

[0039] In order to solve the problem that it is impossible to spray fertilizer on the leaves and / or roots of plants, Fig.18 As shown, any one of the spraying assemblies includes a feed pipe 23, which is connected to the discharge port at the bottom of the branch pipeline 114 and is fixed to the branch pipeline 114; A three-way pipe 24, a first end of which is connected to the bottom of the feed pipe 23; The first branch pipe 25 is connected to the second end of the tee pipe 24 at the top and is arranged below the tee pipe 24, and is connected to the atomizing nozzle 26 at the bottom; The second branch pipe 27 is connected to the third end of the tee pipe 24 at the top and is arranged below the tee pipe 24, and is connected to the diverter plate 28 at the bottom; Several drain pipes 29, the tops of which are connected to the bottom of the diverter plate 28, and the bottoms of which are respectively provided with insertion heads 30; The first branch pipe 25 and the second branch pipe 27 are arranged vertically downward and in parallel.

[0040] In the above technical features, the drainage pipe 29 can be set to a hose form, similar to the pipeline for injecting nutrient solution into landscape trees, which makes it convenient to insert the drainage pipe 29 and the insertion head 30 at the bottom near the roots of different plants, thereby realizing root irrigation, fertilization and spraying of all plants, and improving the utilization rate of fertilizer and drug solutions.

[0041] In order to solve the problem that fertilizer or liquid medicine cannot be discharged into the root position of the plant, Fig.19 As shown, the bottom end of the insertion head 30 is conical and keeps the small end at the bottom, the top end of the insertion head 30 is cylindrical and connected to the drainage pipe 29, the outer diameter of the large end part of the conical end 302 of the insertion head 30 is larger than the outer diameter of the cylindrical end 301 of the insertion head 30 to form a step, and a drainage hole 303 is opened near the step position at the cylindrical end 301 of the insertion head 30, and the drainage hole 303 is connected to the drainage pipe 29.

[0042] In the above technical features, when the tapered end 302 of the insertion head 30 is inserted into the soil beside the root system of the plant until the large end is inside the soil, the crushed soil is then pushed back onto the step, and care is taken not to compact the crushed soil to prevent the drainage hole 303 from being blocked. This ensures that during the drainage process, the liquid medicine or fertilizer is discharged from the drainage pipe 29 and then enters the insertion head 30, and finally is discharged into the soil from the drainage hole 303, making it easier for the root system to absorb the liquid medicine or fertilizer. In this way, not only is it possible to achieve targeted irrigation, fertilization or spraying of the plant roots, thereby improving the utilization rate of the fertilizer and liquid medicine, but it also avoids the insertion head 30 from moving randomly due to the impact force of the liquid during the drainage process, resulting in waste of liquid medicine and fertilizer after the position is moved, and it can also prevent the drainage hole 303 from being blocked by soil when inserted into the soil due to being opened on the tapered end 302.

[0043] In order to solve the problem that part of the liquid medicine may enter the first branch or the second branch, causing the leaves to be scalded by the liquid fertilizer when spraying or fertilizing. Figure 20-23As shown, the three-way pipe 24 includes a tube body 241 with three pipe openings distributed in a circle, a control member 242, a rotating shaft 243, a first valve plate 244 and a second valve plate 245. The rotating shaft 243 is rotatably installed at the center position of the three pipe openings inside the tube body 241. The control member 242 is arranged outside the tube body 241 to fix and drive the rotating shaft 243 to rotate. The first valve plate 244 and the second valve plate 245 are both arranged on the outer end of the rotating shaft 243 inside the tube body 241 and maintain the angle between the two valve plates at 120°.

[0044] like Fig.21 As shown, when the control member 242 drives the rotating shaft 243 to rotate to the first position, it is the first working state. At this time, the first valve plate 244 is in the middle position between the two pipe openings at the bottom of the tube body 241, and the second valve plate 245 is in the middle position between the two pipe openings on the left side of the tube body 241. In this way, the top pipe opening of the tube body 241 is kept connected to the right pipe opening, while the top pipe opening is disconnected from the left pipe opening. It can be seen that the first working state is to fertilize, spray and irrigate the roots of the plants.

[0045] like Fig. 22 As shown, when the control member 242 drives the rotating shaft 243 to rotate to the second position, it is the second working state. At this time, the first valve plate 244 is in the middle position between the two pipe openings on the right side of the tube body 241, and the second valve plate 245 is in the middle position between the two pipe openings at the bottom of the tube body 241. In this way, the top pipe opening of the tube body 241 is kept connected to the left pipe opening, while the top pipe opening is disconnected from the right pipe opening. It can be seen that the second working state is to fertilize, spray and irrigate the leaves of the plants.

[0046] like Fig.23 As shown, when the control member 242 drives the rotating shaft 243 to rotate to the third position, it is the third working state. At this time, the first valve plate 244 and the second valve plate 245 are respectively at the two pipe openings at the bottom of the pipe body 241. In this way, the three pipe openings of the pipe body 241 are kept in a connected state. It can be seen that the third working state is to fertilize and spray the leaves and roots of the plant at the same time. The control member 242 can be a micro motor. The appropriate working state of the three-way pipe 24 can be selected according to the different needs of different plants.

[0047] The shed main body 1 of the planting shed can adopt a steel frame structure, and its top is a herringbone shape. The transparent top plate 3 can be made of glass material to ensure light transmittance. The photovoltaic panel 5 can adopt an existing conventional solar panel to convert light energy into electrical energy and store it in a battery. The fan 7 can adopt a conventional axial flow fan to blow positive pressure air into the shed. The sunshade 9 can be made of soft material to ensure that it can be wrapped around the outside of the rotating rod 19. The linear telescopic device 12 can be made of an electric push rod that is easy to automatically control by electric means. The liquid inlet component 1 The liquid inlet valve 113 of 1 can also be set as a commonly used electric water valve, and the temperature sensor 14, humidity sensor 15, distance sensor 16, image sensor 17 and light sensor 18 can all adopt existing conventional sensors, which can realize the detection of temperature, humidity, distance from the highest height of the plant, plant image and sunlight energy. Some other sensors can also be added, such as a CO2 detection sensor, which is used to detect the CO2 concentration in the planting shed and adjust it through the ventilation mechanism. The battery can be a conventional battery, and the atomizing nozzle 26 can also adopt an existing conventional atomizing nozzle.

[0048] In the agricultural planting shed, the ventilation mechanism, fertilization spraying and watering mechanism, sunshade curtain and fill light in the planting shed correspond to the environmental compensation module in the control system.

[0049] In another embodiment, a control method for an agricultural planting shed is also provided. The control method is applied to the above-mentioned planting shed and the control system of the planting shed. Figure 2 As shown, the method comprises the following steps: S100: Obtaining and storing basic information of plants in the planting shed; Exemplarily, the basic information of plants in the planting shed is obtained and stored, which means that plants (including vegetables and fruits) are planted in the planting shed, and then multiple insertion heads 30 are respectively inserted into the sides of the root system of each plant through the conical end 302 according to the position of the plants, and fixed on the steps by covering them with crushed soil, and then the information of the plants (including the planting time information of the plants, the type information of the plants, the current plant images and the image information of the plants at different growth stages, the environmental information required by the plants at different growth stages, etc.) is stored in the plant database through the input and output module; The acquisition of basic information of plants in the planting shed also includes plant image information, plant height information and plant color information acquired in real time by the acquisition module (ie, the distance sensor 16 and the image sensor 17 ).

[0050] S200: determining the growth environment information required for the acquired plant information by matching and comparing the acquired plant basic information with the original plant information in the plant database; Exemplarily, determining the growth environment information required for the acquired plant information by matching and comparing the acquired basic plant information with the original plant information in the plant database refers to matching and comparing the plant image information detected by the acquisition module with the original plant information in the plant database. If the plant image information is not in the plant database, the analysis and control module sends a warning message to the input and output module, indicating that the plant information has not been entered into the plant database by the staff, and the staff needs to supplement it or perform other processing. If the detected plant image information is consistent with any original plant information in the plant database, the environmental information required for the plant is further determined based on the plant image information and plant height information, and at the same time, it is determined whether the plant needs to be fertilized or sprayed based on the plant image information, plant height information and plant color information.

[0051] S300: obtaining real-time environmental information in the planting shed; Exemplarily, the acquisition of real-time environmental information in the planting shed refers to determining the current environmental information in the planting shed through an acquisition module (i.e., temperature sensor 14, humidity sensor 15, light sensor 18), and the environmental information specifically includes air temperature, humidity and light intensity information in the planting shed.

[0052] S400: Automatically adjust the real-time environmental information according to the growth environment information required by the acquired basic information of the plant.

[0053] Exemplarily, in the first aspect, the automatic control of real-time environmental information based on the growth environment information required by the acquired basic information of the plants refers to comparing and analyzing the current environmental information in the planting shed with the environmental information required by the plants to determine whether the air temperature, humidity and light intensity in the planting shed need to be automatically adjusted.

[0054] The automatic adjustment method is to adjust the temperature, humidity and light intensity inside the planting shed through the analysis control module and the environmental compensation module. The specific adjustment method is as follows: When adjusting the temperature, the control module first analyzes the instructions issued by the control module to control the electronic push rod 22 to extend or retract. When extending, it drives the wind shield 20 to flip to coincide with the vent of the side panel 2, thereby blocking the vent and isolating the air inside the planting shed from the outside, thereby increasing the temperature inside the planting shed. When retracting, it drives the wind shield 20 to flip to be perpendicular to the vent of the side panel 2, and the vent is opened to dissipate heat, thereby reducing the air temperature inside the planting shed.

[0055] When adjusting the humidity, the analysis and control module issues a command to open the liquid inlet valve 113 in the liquid inlet assembly 11 that is connected to the external water source, and then drives the rotating shaft 243 to rotate to the second position through the control component 242, so that the three-way pipe 24 is in the second working state to spray the leaf surface, thereby increasing the humidity in the greenhouse, or the analysis and control module issues a command to control the electronic push rod 22 to retract and open the vent, and start the fan 7 to supply air to the greenhouse, thereby reducing the humidity in the greenhouse.

[0056] When adjusting the light, the analysis and control module issues an instruction, first the driving motor 10 is de-energized to make the rotating rod 19 in a free rotation state, and then the linear telescopic device 12 is started to retract, and the limit plate 13 at the end of the linear telescopic device 12 pulls the sunshade 9 to move toward the position of the middle plate 83 to block the sunlight, thereby reducing the light intensity, or the linear telescopic device 12 is started to extend, and then the driving motor 10 is powered to roll up the sunshade 9 until the connector 91 at the end of the sunshade 9 is limited by the limit plate 13, and then the driving motor 10 stops rotating, so that the plant is in direct contact with the sunlight, thereby increasing the light intensity, or an instruction is issued by the analysis and control module to control the fill light to turn on (such as when the light is weak on a cloudy day), thereby increasing the light intensity.

[0057] In the second aspect, the automatic regulation of real-time environmental information based on the growth environment information required by the acquired basic information of the plant refers to determining whether the current plant needs to be sprayed or fertilized based on the real-time acquired plant image information, plant height information and plant color information.

[0058] The spraying fertilization is to spray liquid fertilizer on the leaves and / or roots of the plants through the analysis control module and the environmental compensation module. The specific operation method is as follows: Before fertilizing and spraying, the plant is fertilized and sprayed according to the plant image (for example, if the plant image shows holes on the leaf surface, it means there may be insects and spraying is required; if the plant image is yellowish, it means that fertilizer may need to be added) or the height or plant growth time through the fertilization and spraying module. In this process, an early warning message is sent in advance through the input and output module to prompt the staff to mix medicine or fertilizer in time. The staff mixes medicine or fertilizer in the external mixing barrel. After completion, the liquid inlet pipe 112 is connected to the external mixing barrel through the analysis and control module to carry out fertilization and spraying; Then adjust the state of the three-way pipe 24 according to the fertilization and spraying method required by the plant; If the plant needs foliar fertilization and spraying, the control member 242 drives the rotating shaft 243 to rotate to the second position. At this time, the first valve plate 244 is in the middle position between the two pipe openings on the right side of the tube body 241, and the second valve plate 245 is in the middle position between the two pipe openings at the bottom of the tube body 241. In this way, the top pipe opening of the tube body 241 is kept connected with the left pipe opening, while the top pipe opening is disconnected from the right pipe opening. At this time, the liquid medicine or fertilizer in the mixing barrel enters the main pipeline 111 through the liquid inlet pipe 112 and then flows into each branch pipeline 114, and then enters the three-way pipe 24 through the discharge pipe 23 and flows through the first branch pipe 25, and finally is discharged from the atomizing nozzle 26 in atomization (a pump body can be set on the external pipeline of the mixing barrel to increase the liquid flow rate to achieve atomization), thereby realizing foliar fertilization and spraying.

[0059] If the plant needs root fertilization and spraying, the control member 242 drives the rotating shaft 243 to rotate to the first position, which is the first working state. At this time, the first valve plate 244 is in the middle position between the two pipe openings at the bottom of the tube body 241, and the second valve plate 245 is in the middle position between the two pipe openings on the left side of the tube body 241. In this way, the top pipe opening of the tube body 241 is kept connected with the right pipe opening, while the top pipe opening is disconnected from the left pipe opening. At this time, the medicine liquid or fertilizer liquid in the mixing barrel enters the main pipeline 111 through the liquid inlet pipe 112 and then flows into each branch pipeline 114, and then enters the tee pipe 24 through the feed pipe 23 and flows through the second branch pipe 27 and the diverter plate 28, and finally is discharged into the soil from each drain pipe 29 and the drain hole 303 of the insertion head 30, thereby realizing root fertilization and spraying.

[0060] If the plant needs to be fertilized and sprayed on the leaves and roots at the same time, the control member 242 drives the rotating shaft 243 to rotate to the third position, which is the third working state. At this time, the first valve plate 244 and the second valve plate 245 are respectively at the two pipe openings at the bottom of the tube body 241. In this way, the three pipe openings of the tube body 241 are kept in a connected state. At this time, the liquid medicine or fertilizer liquid in the mixing barrel enters the main pipeline 111 through the liquid inlet pipe 112 and then flows into each branch pipeline 114. Then, after entering the three-way pipe 24 through the discharge pipe 23, a part of the liquid flows through the first branch pipe 25 and is finally discharged from the atomizing nozzle 26 in atomization (a pump body can be set on the external pipeline of the mixing barrel to increase the liquid flow rate to achieve atomization), realizing foliar fertilization and spraying, and the other part of the liquid flows through the second branch pipe 27 and the diverter plate 28, and is finally discharged into the soil from each drainage pipe 29 and the drainage hole 303 of the insertion head 30, realizing foliar and root fertilization and spraying at the same time.

[0061] The above methods all issue control instructions through the analysis control module to activate the control component 242 to adjust the working state of the three-way pipe 24, thereby realizing automatic fertilization and spraying of pesticides to the plants and improving the degree of automation.

[0062] Specifically, the basic information of the plant includes plant image, plant height and plant color. The matching and comparison is to match and compare the acquired basic information of the plant with the original plant information in the plant database. If the plant image in the acquired basic information of the plant is the same as any original plant information in the plant database, the acquired basic information of the plant is further matched and compared with the plant height and plant color of the corresponding original plant information in the plant database, so as to determine the growth environment information required for the acquired basic information of the plant. If the plant image in the acquired basic information of the plant is different from all the original plant information in the plant database, a warning message is issued.

[0063] Specifically, the basic information of the plants also includes the seedling information of the plants and the time information of the plants growing in the planting shed. The methods of obtaining the basic information of the plants in the planting shed include manual acquisition and automatic acquisition. The manual acquisition of the basic information of the plants is the seedling information of the plants and the time information of the plants growing in the planting shed. The manual acquisition of the basic information of the plants is stored in the plant database. The automatic acquisition of the basic information of the plants is the plant image, plant height and plant color. The automatic acquisition of the basic information of the plants is matched and compared with the original plant information in the plant database.

[0064] Specifically, the environmental information includes temperature and humidity information, light intensity information and required fertilizer and pesticide information during plant growth. The automatic control real-time environmental information is: Automatically adjust the temperature and humidity in the planting shed according to the real-time environmental information in the planting shed to within the temperature and humidity information threshold range in the required growth environment information after plant matching and comparison; Automatically adjust the light intensity in the planting shed according to the real-time environmental information in the planting shed to within the light intensity information threshold range in the required growth environment information after plant matching and comparison; Liquid fertilizers and pesticides are automatically applied to the leaves and / or roots of the plants based on the growth environment information required by the acquired basic information of the plants.

[0065] According to the above control method, the automatic adjustment of air temperature, humidity and light in the planting shed can be realized, and the automatic fertilization, spraying and watering of the leaves and / or roots of the plants can be realized at the same time, which effectively improves the efficiency of plant growth. The high degree of automation greatly reduces the intensity and cost of manual management, and is convenient for large-scale promotion in the agricultural field.

All equivalent changes or modified changes completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
