Description

Technical Field

[0001] This invention relates to the field of mushroom spawn cultivation rack technology, and more specifically, to an intelligent integrated mushroom spawn cultivation rack for color change and bud induction, and its collaborative control method. Background Technology

[0002] The intelligent integrated shiitake mushroom spawn cultivation rack and its collaborative control method is a three-dimensional cultivation device that integrates environmental perception, intelligent decision-making, and precise execution. Its core innovation lies in the collaborative control method, which uses an algorithm to simulate and regulate two distinctly different microenvironments most suitable for shiitake mycelial color change and primordia (bud) formation in stages and automatically on the same cultivation rack.

[0003] In the current cultivation of shiitake mushroom spawn, the color-changing stage and the bud-inducing stage are two critical phases with significantly different environmental requirements. The color-changing stage requires a temperature of 18-22℃, humidity of 80-85%, and a low-light environment to promote the mycelium's transformation from white to brown; the bud-inducing stage requires a temperature of 10-15℃, humidity of 85-90%, and diffused light stimulation to induce primordia formation. However, traditional cultivation methods have the following problems:

[0004] 1. Inadequate environmental control: Most culture racks use a single environmental parameter adjustment, which cannot meet the different needs of color change and bud induction in the same culture space at the same time, resulting in uneven color change of the mushroom logs and delayed bud induction, affecting yield and quality.

[0005] 2. Reliance on manual judgment: The identification of the growth stage of the mushroom sticks mainly relies on manual visual inspection, which is inefficient, highly subjective, and makes it difficult to accurately judge the completion of color change, and it is easy to miss the best time for transfer.

[0006] 3. Low transfer efficiency: The transfer of mushroom sticks from the color change area to the bud induction area requires manual handling, which is labor-intensive. In addition, the frequent opening and closing of the cultivation environment can easily cause fluctuations in temperature and humidity, which can interfere with the normal development of the mushroom sticks.

[0007] 4. Lack of closed-loop control: Existing equipment cannot monitor environmental parameters in real time and adjust them automatically. It cannot recover in time after environmental fluctuations, which affects the uniformity of mushroom growth. Summary of the Invention

[0008] In view of the problems in the existing technology, such as extensive environmental control, easy error in manual judgment of the growth stage of the mushroom sticks, low transfer efficiency and lack of closed-loop regulation, the purpose of this invention is to provide an intelligent color change and bud induction integrated shiitake mushroom stick cultivation rack and its collaborative control method.

[0009] To solve the above problems, the present invention adopts the following technical solution;

[0010] The intelligent integrated color-changing and bud-inducing shiitake mushroom spawn cultivation rack includes a box body. A partition is fixedly connected to the inner wall of the box body. Multiple sets of through holes are opened on the left and right sides of the box body and on the partition. A sealing mechanism is provided on the inner wall of each through hole to seal it. A conveyor belt for transporting spawn is installed between adjacent through holes. Two environmental control mechanisms are provided on the back of the box body to control the environment of the areas on the left and right sides of the partition. A status recognition mechanism for identifying the growth status of the spawn is provided above the conveyor belt.

[0011] As a further description of the above technical solution:

[0012] The status recognition mechanism includes a guide rail, both ends of which are fixedly connected to the inner wall of the box. An electric slider is installed on the inner wall of the guide rail, and a camera for collecting image information of the mushroom sticks is fixedly connected to the bottom of the electric slider. A status recognition module for analyzing and judging the growth status of the mushroom sticks is provided on the left side of the box.

[0013] As a further description of the above technical solution:

[0014] The state recognition module includes a controller. The input end of the electric slider is connected to the controller. The controller integrates an image feature extraction module, a feature comparison module, and a feature database. The output end of the camera is connected to the image feature extraction module. The output ends of the image feature extraction module and the feature database are both connected to the feature comparison module. A positioning module is installed on the front of the electric slider. The output ends of the feature comparison module and the positioning module are both connected to the controller.

[0015] As a further description of the above technical solution:

[0016] The environmental control mechanism includes a housing, the front of which is fixedly connected to a box body. An electric heating plate and a cooling element are fixedly connected to the inner wall of the housing. The cold side of the cooling element is located inside the housing, and the hot side extends through and to the outside of the housing. An air inlet duct and a return duct are fixedly connected to the front of the housing and communicate with it. The front of the air inlet duct extends through and into the interior of the box body, and one end of the front of the return duct extends to the front of the box body and communicates with it. A fan and a humidifier are installed on the return duct. A ventilation mechanism is provided on the housing. An environmental data acquisition mechanism is provided inside the housing. A mounting plate is fixedly connected to the inner wall of the housing. LED lights arranged at equal intervals are installed at the bottom of the mounting plate. An environmental adjustment module is integrated inside the controller. The output of the environmental adjustment module is connected to the electric heating plate, the cooling element, the fan, the humidifier, and the LED lights.

[0017] As a further description of the above technical solution:

[0018] The ventilation mechanism includes two ducts, one end of which is connected to the top and front of the housing, respectively. Both ducts are equipped with solenoid valves, and a second fan is installed on the front duct. The input ends of the solenoid valves and the second fan are connected to the environmental control module.

[0019] As a further description of the above technical solution:

[0020] The environmental data acquisition mechanism includes a temperature sensor, a humidity sensor, a carbon dioxide sensor, and a light sensor. One side of each of the temperature sensor, humidity sensor, carbon dioxide sensor, and light sensor is fixedly connected to an electric slider. The output terminals of each of the temperature sensor, humidity sensor, carbon dioxide sensor, and light sensor are connected to the environmental control module.

[0021] As a further description of the above technical solution:

[0022] The bottom of the camera is electroplated with a hydrophobic layer, and the back of the housing has several maintenance ports, the inner wall of which is threaded with a maintenance window.

[0023] The present invention also provides a collaborative control method for an intelligent color-changing and bud-inducing integrated shiitake mushroom spawn culture rack, comprising the following steps;

[0024] S1. The electric slider in the status recognition mechanism moves along the guide rail, driving the camera to scan the mushroom sticks on each conveyor belt in sequence and collect image information of the surface of the mushroom sticks.

[0025] S2. The camera transmits the image signal to the image feature extraction module in the status recognition module to extract feature parameters such as the color of the mushroom stick, mycelial coverage, and proportion of color-changing patches.

[0026] S3. The feature comparison module compares the extracted features with the pre-stored standard features of the color change period (mycelium turns from white to brown and brown patches appear on the surface) and the standard features of the budding period (white primordia protrusions appear on the brown mycelial surface) in the feature database to determine the current growth stage (color change period or budding period) and the degree of color change completion of each mycelium.

[0027] S4. The positioning module records the specific position of the mushroom stick on the conveyor belt and sends the judgment result and position information to the controller.

[0028] S5. Based on the results of S3 and S4, the controller issues zoned environmental parameter commands to the environmental control mechanisms of the left and right sides of the partition through the internally integrated environmental adjustment module.

[0029] S6. For the area on the left side of the partition where the color-changing mushroom sticks are located, the environmental control module controls the heating plate or cooling element to adjust the temperature of the color-changing area to the temperature required by the color-changing mushroom sticks; the environmental control module controls the humidifier and fan one to adjust the humidity of the color-changing area to the humidity required by the color-changing mushroom sticks; the environmental control module adjusts the light intensity of the color-changing area to the light intensity required by the color-changing mushroom sticks by turning off or dimming the LED lights; the environmental control module controls the solenoid valve and fan two in the ventilation mechanism to adjust the carbon dioxide concentration of the color-changing area to the carbon dioxide concentration required by the color-changing mushroom sticks.

[0030] S7. Similarly, for the area where the budding stage mushroom sticks are located on the right side of the partition, the environmental control module can adjust the temperature, humidity, light intensity and carbon dioxide concentration of the area where the budding stage mushroom sticks are located on the right side of the partition to the values ​​required for the budding stage mushroom sticks.

[0031] S8. The temperature sensor, humidity sensor, carbon dioxide sensor, and light sensor in the environmental data acquisition mechanism monitor the environmental parameters of each area in real time and feed the data back to the environmental control module to dynamically adjust the actuators such as the electric heating plate, cooling chip, fan one, humidifier, LED light, solenoid valve, and fan two to form a closed-loop control.

[0032] S9. If the controller determines that a certain mushroom log has completed color change (the feature comparison reaches the color change completion threshold), it controls the electric push rod in the closed mechanism corresponding to the conveyor belt where the mushroom log is located to move, drive the sealing plate to slide along the through hole to open the through hole, start the conveyor belt, and transport the mushroom log from the color change area to the bud induction area.

[0033] S10. After the mushroom stick reaches the budding area, the controller controls the electric push rod of the corresponding sealing mechanism to close the through hole, keeping the left and right sides of the partition isolated. At the same time, the status information of the mushroom stick is updated to the feature database, and steps S1 to S9 are repeated to achieve fully automatic cyclic collaborative control.

[0034] Compared with the prior art, the advantages of this invention are:

[0035] Precise zoned control: The box is divided into independent environmental zones by partitions, and the temperature, humidity, light and carbon dioxide concentration are adjusted separately by the environmental control mechanism. This meets the different needs of the color change period and the bud induction period, avoids environmental interference and improves the uniformity of mushroom growth.

[0036] Intelligent identification and automatic transfer: Utilizing a camera and image feature extraction and comparison module, the system automatically identifies the growth stage and color change completion of the mushroom sticks. Combined with a positioning module and conveyor belt, it realizes the automatic transfer of mushroom sticks from the color change area to the bud induction area without manual intervention, greatly improving efficiency.

[0037] Closed-loop environmental control: Data is collected in real time by temperature, humidity, carbon dioxide and light sensors, and fed back to the environmental regulation module to dynamically adjust the actuators, ensuring that environmental parameters are stable within the set range and reducing the impact of fluctuations on the development of the mushroom sticks.

[0038] Regional isolation and energy saving: The closed mechanism can precisely control the opening and closing of the through holes, which can be opened briefly during transportation and closed immediately after transportation, effectively maintaining the environmental independence of each area and reducing energy consumption and cross-interference.

[0039] On-demand transfer: Since the growth rates of mushroom logs in the same batch vary, logs that have reached the budding stage can be selected and transferred to the budding stage area. This solves the problem of traditionally transferring all logs in the same batch directly to the budding stage area after most of them have reached the budding stage, which may result in some logs that have not reached the budding stage, causing problems for those logs and affecting the quality of the shiitake mushrooms.

[0040] Fully automated operation: From image acquisition, stage judgment, environmental control to mushroom stick transportation, the entire process is completed automatically by the controller, reducing labor costs and improving the standardization and intelligence of the cultivation process.

[0054] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0055] To address the problems of traditional culture rack cultivation methods, such as inefficient environmental control, susceptibility to errors in manually judging the growth stage of the substrate, low transfer efficiency, and lack of closed-loop regulation, this solution provides Example 1:

[0056] Please see Figures 1-11 In this invention: the intelligent color-changing and bud-inducing integrated shiitake mushroom spawn cultivation rack includes a box body 1. A partition 2 is fixedly connected to the inner wall of the box body 1. Multiple sets of through holes 3 are opened on the left and right sides of the box body 1 and on the partition 2. A sealing mechanism 4 is provided on the inner wall of the through holes 3 to seal the through holes 3. A conveyor belt 5 for conveying spawn is installed between two adjacent through holes 3. Two environmental control mechanisms 6 for controlling the environment of the left and right sides of the partition 2 are provided on the back of the box body 1. A status recognition mechanism 7 for identifying the growth status of spawn is provided above the conveyor belt 5. The status recognition mechanism 7 includes a guide rail 71.

A camera 73 for collecting image information of spawn is fixedly connected to the bottom of the electric slider 72.

[0057] On the left side of the housing 1, there is a status recognition module 74 for analyzing and judging the growth status of the mushroom sticks. The status recognition module 74 includes a controller 701. The input end of the electric slider 72 is connected to the controller 701. The controller 701 integrates an image feature extraction module 702, a feature comparison module 703, and a feature database 704. The output end of the camera 73 is connected to the image feature extraction module 702. The output ends of the image feature extraction module 702 and the feature database 704 are both connected to the feature comparison module 703. A positioning module 705 is installed on the front of the electric slider 72. The output ends of the feature comparison module 703 and the positioning module 705 are both connected to the controller 701.

[0058] The environmental control mechanism 6 includes a housing 61, the front of which is fixedly connected to the enclosure 1. An electric heating plate 62 and a cooling element 63 are fixedly connected to the inner wall of the housing 61. The cold side of the cooling element 63 is located inside the housing 61, and the hot side of the cooling element 63 extends through and to the outside of the housing 61. An air inlet duct 64 and a return air duct 65 are fixedly connected to and communicate with the front of the housing 61. The front of the air inlet duct 64 extends through and into the interior of the enclosure 1, and one end of the front of the return air duct 65 extends to and communicates with the front of the enclosure 1. A fan 66 and a humidifier 67 are installed on the return air duct 65. A ventilation mechanism 68 is provided on the housing 1. An environmental data acquisition mechanism 69 is provided inside the housing 1. An installation plate 610 is fixedly connected to the inner wall of the housing 1. LED lights 611 arranged at equal intervals are installed at the bottom of the installation plate 610. An environmental control module 612 is integrated inside the controller 701. The output terminal of the environmental control module 612 is connected to the heating plate 62, the cooling chip 63, the fan 66, the humidifier 67 and the LED lights 611 respectively.

[0059] The ventilation mechanism 68 includes two ducts 81, one end of which is connected to the top and front of the housing 1 respectively. Solenoid valves 82 are installed on both ducts 81. Fan 83 is installed on the front duct 81. The input ends of the solenoid valves 82 and the fan 83 are connected to the environmental control module 612.

[0060] The environmental data acquisition mechanism 69 includes a temperature sensor 91, a humidity sensor 92, a carbon dioxide sensor 93, and a light sensor 94. One side of each of the temperature sensor 91, humidity sensor 92, carbon dioxide sensor 93, and light sensor 94 is fixedly connected to an electric slider 72. The output terminals of each of the temperature sensor 91, humidity sensor 92, carbon dioxide sensor 93, and light sensor 94 are connected to the environmental control module 612.

[0061] The closing mechanism 4 includes a fixed plate 41, the bottom of which is fixedly connected to the inner bottom wall of the through hole 3. An electric push rod 42 is fixedly connected to the inner top wall of the through hole 3. A sealing plate 43 is fixedly connected to the telescopic end of the electric push rod 42. The outer side of the sealing plate 43 is slidably connected to the inner wall of the through hole 3. The input end of the electric push rod 42 is signal-connected to the controller 701.

[0062] In this invention, the partition 2 divides the box 1 into two parts. The box 1 area on the left side of the partition 2 is the area where the color-changing period mushroom sticks are located, and the box 1 area on the right side of the partition 2 is the area where the bud-inducing period mushroom sticks are located. Mushroom sticks can be placed on the top of each conveyor belt 5.

[0063] In actual use, the electric slider 72 moves along the guide rail 71, driving the camera 73 to scan the mushroom sticks on each conveyor belt 5 in sequence and collect image information of the mushroom stick surface.

[0064] The camera 73 transmits the image signal to the image feature extraction module 702 in the status recognition module 74 to extract feature parameters such as the color of the mushroom stick, mycelial coverage, and proportion of color-changing patches;

[0065] The feature comparison module 703 compares the extracted features with the pre-stored standard features of the color change period in the feature database 704, namely, the mycelium turning from white to brown, the appearance of brown patches on the surface, and the standard features of the budding period, namely, the appearance of white primordia protrusions on the surface of the brown mycelium, to determine the current growth stage of each mycelium stick, namely, the color change period or the budding period, and the degree of color change completion.

[0066] The positioning module 705 records the specific position of the mushroom stick on the conveyor belt 5 and sends the judgment result and position information to the controller 701.

[0067] According to the current growth stage of each mushroom stick, namely the color change stage or the bud induction stage, and the color change completion result, the controller 701 issues zoned environmental parameter commands to the environmental control mechanisms 6 on the left and right sides of the partition 2 through the environmental adjustment module 612.

[0068] During the process, for the area where the color-changing mushroom sticks are located on the left side of partition 2, fan 66 operates, and the air in the color-changing area circulates in the box 61 through the air inlet pipe 64 and the air return pipe 65. During the process, the environmental regulation module 612 compares the temperature of the area where the color-changing mushroom sticks are located, collected by the temperature sensor 91, with the temperature value required for the color-changing mushroom sticks. If the temperature is higher than the set value, the cooling plate 63 is activated; if it is lower than the set value, the heating plate 62 is activated. By controlling the heating plate 62 or the cooling plate 63, the temperature in the box 61 is adjusted to a suitable temperature, thereby achieving the effect of adjusting the temperature of the color-changing area to the temperature required for the color-changing mushroom sticks.

[0069] The environmental control module 612 compares the humidity collected by the humidity sensor 92 with the humidity value required for the color-changing period of the mushroom sticks. If the humidity is low, the humidifier 67 is turned on. The humidifier 67 humidifies the circulating air, thereby increasing the air humidity in the area where the color-changing period mushroom sticks are located, and adjusting the humidity of the area to the humidity required for the color-changing period mushroom sticks.

[0070] The environmental control module 612 compares the light intensity detected by the light sensor 94 in the color-changing area with the light intensity required for the color-changing area. If the light is too strong, the LED light 611 is turned off or dimmed to adjust the light intensity in the color-changing area to the light intensity required for the color-changing mushroom sticks.

[0071] The environmental control module 612 compares the carbon dioxide concentration in the color-changing area detected by the carbon dioxide sensor 93 with the carbon dioxide concentration required for the color-changing area, and controls the solenoid valve 82 and the fan 83 in the ventilation mechanism 68 to ventilate the color-changing area and adjust the carbon dioxide concentration in the color-changing area to the carbon dioxide concentration required for the color-changing mushroom sticks.

[0072] Similarly, for the area where the budding stage mushroom sticks are located on the right side of partition 2, the environmental control module 612 can adjust the temperature, humidity, light intensity, and carbon dioxide concentration of the area to the values ​​required for the budding stage mushroom sticks.

[0073] If the controller 701 determines that a certain mushroom stick has completed the color change feature comparison and reached the color change completion threshold, it controls the electric push rod 42 in the sealing mechanism 4 corresponding to the conveyor belt 5 where the mushroom stick is located to move, drive the sealing plate 43 to slide along the through hole 3 to open the through hole 3, start the conveyor belt 5, and transport the mushroom stick from the color change area to the bud induction area.

[0074] After the mushroom stick reaches the budding area, the controller 701 controls the electric push rod 42 of the corresponding sealing mechanism 4 to close the through hole 3, keeping the left and right sides of the partition 2 isolated. At the same time, the status information of the mushroom stick is updated to the feature database 704, and the above operation is repeated to achieve fully automatic cyclic collaborative control.

[0075] In practical use, the camera lens is susceptible to moisture, resulting in condensation, which affects the quality of image acquisition. To address this issue, this solution provides Embodiment Two:

[0076] Please see Figures 3-6 Among them: the bottom of the camera 73 is electroplated with a hydrophobic layer, and the back of the housing 1 has several maintenance ports 8, and the inner wall of the maintenance ports 8 is threaded with a maintenance window 9.

[0077] In this invention, the bottom of the camera 73 is electroplated with a hydrophobic layer, which can effectively prevent condensation on the lens of the camera 73. If condensation occurs, it will affect the image acquisition effect of the camera 73. The worker can open the maintenance port 8 by rotating the maintenance window 9, and the worker can maintain the camera 73. The process is very convenient and quick, which improves the practicality of the device.

[0078] The present invention also provides a collaborative control method for an intelligent color-changing and bud-inducing integrated shiitake mushroom spawn culture rack, comprising the following steps;

[0079] S1. The electric slider 72 in the status recognition mechanism 7 moves along the guide rail 71, driving the camera 73 to scan the mushroom sticks on each conveyor belt 5 in sequence and collect image information of the surface of the mushroom sticks.

[0080] S2, the camera 73 transmits the image signal to the image feature extraction module 702 in the state recognition module 74 to extract feature parameters such as the color of the mushroom stick, mycelial coverage, and the proportion of color-changing patches;

[0081] S3. The feature comparison module 703 compares the extracted features with the pre-stored standard features of color change period mycelium turning from white to brown, brown patches appearing on the surface, and standard features of bud induction period brown mycelium with white primordia protrusions on the surface of the brown mycelium to determine the current growth stage of each mycelium stick, color change period or bud induction period, and the degree of color change completion.

[0082] S4. The positioning module 705 records the specific position of the mushroom stick on the conveyor belt 5 and sends the judgment result and position information to the controller 701.

[0083] S5, based on the results of S3 and S4, controller 701 issues zoned environmental parameter commands to the environmental control mechanisms 6 on the left and right sides of the partition 2 through the internally integrated environmental adjustment module 612.

[0084] S6. For the area on the left side of partition 2 where the color-changing period mushroom sticks are located, the environmental control module 612 controls the heating plate 62 or the cooling element 63 to adjust the temperature of the color-changing period area to the temperature required by the color-changing period mushroom sticks; the environmental control module 612 controls the humidifier 67 and the first fan 66 to adjust the humidity of the color-changing period area to the humidity required by the color-changing period mushroom sticks; the environmental control module 612 adjusts the light intensity of the color-changing period area to the light intensity required by the color-changing period mushroom sticks by turning off or dimming the LED light 611; the environmental control module 612 controls the solenoid valve 82 and the second fan 83 in the ventilation mechanism 68 to adjust the carbon dioxide concentration of the color-changing period area to the carbon dioxide concentration required by the color-changing period mushroom sticks.

[0085] S7. Similarly, for the area where the budding stage mushroom sticks are located on the right side of partition 2, the environmental control module 612 can adjust the temperature, humidity, light intensity and carbon dioxide concentration of the area where the budding stage mushroom sticks are located on the right side of partition 2 to the values ​​required for the budding stage mushroom sticks.

[0086] S8, the temperature sensor 91, humidity sensor 92, carbon dioxide sensor 93, and light sensor 94 in the environmental data acquisition mechanism 69 monitor the environmental parameters of each area in real time and feed the data back to the environmental control module 612, which dynamically adjusts the actuators such as the electric heating plate 62, the cooling chip 63, the first fan 66, the humidifier 67, the LED light 611, the solenoid valve 82, and the second fan 83 to form a closed-loop control.

[0087] S9. If the controller 701 determines that a certain mushroom stick has completed the color change feature comparison and reached the color change completion threshold, it controls the electric push rod 42 in the sealing mechanism 4 corresponding to the conveyor belt 5 where the mushroom stick is located to move, drive the sealing plate 43 to slide along the through hole 3 to open the through hole 3, start the conveyor belt 5, and transport the mushroom stick from the color change area to the bud induction area.

[0088] S10. After the mushroom stick reaches the budding area, the controller 701 controls the electric push rod 42 of the corresponding sealing mechanism 4 to close the through hole 3, keeping the left and right sides of the partition 2 isolated. At the same time, the status information of the mushroom stick is updated to the feature database 704, and steps S1 to S9 are repeated to achieve fully automatic cyclic collaborative control.

[0089] The above are merely preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.

9. A synergistic control method for an integrated intelligent color-changing and bud-inducing shiitake mushroom substrate culture rack, applicable to any one of claims 1-8, comprising the following steps: S1. The electric slider (72) in the status recognition mechanism (7) moves along the guide rail (71) to drive the camera (73) to scan the mushroom sticks on each conveyor belt (5) in sequence and collect the image information of the mushroom stick surface. S2, the camera (73) transmits the image signal to the image feature extraction module (702) in the state recognition module (74) to extract feature parameters such as the color of the mushroom stick, mycelial coverage, and proportion of color-changing patches; S3. The feature comparison module (703) compares the extracted features with the pre-stored color change period standard features (mycelium turns from white to brown and brown spots appear on the surface) and budding period standard features (white primordia protrusions appear on the brown mycelium surface) in the feature database (704) to determine the current growth stage (color change period or budding period) and color change completion of each mycelium stick. S4. The positioning module (705) records the specific position of the mushroom stick on the conveyor belt (5) and sends the judgment result and position information to the controller (701). S5. The controller (701) issues zoned environmental parameter commands to the environmental control mechanisms (6) on the left and right sides of the partition (2) respectively through the internally integrated environmental adjustment module (612) based on the results of S3 and S4. S6. For the area where the color-changing period mushroom sticks are located on the left side of the partition (2), the environmental control module (612) controls the electric heating plate (62) or the cooling plate (63) to adjust the temperature of the color-changing period area to the temperature required by the color-changing period mushroom sticks; the environmental control module (612) controls the humidifier (67) and the first fan (66) to adjust the humidity of the color-changing period area to the humidity required by the color-changing period mushroom sticks; the environmental control module (612) adjusts the light intensity of the color-changing period area to the light intensity required by the color-changing period mushroom sticks by turning off or dimming the LED lights (611); the environmental control module (612) controls the solenoid valve (82) and the second fan (83) in the ventilation mechanism (68) to adjust the carbon dioxide concentration of the color-changing period area to the carbon dioxide concentration required by the color-changing period mushroom sticks; S7. Similarly, for the area where the budding period mushroom sticks are located on the right side of the partition (2), the environmental regulation module (612) can adjust the temperature, humidity, light intensity and carbon dioxide concentration of the area where the budding period mushroom sticks are located on the right side of the partition (2) to the values ​​required for the budding period mushroom sticks. S8, the temperature sensor (91), humidity sensor (92), carbon dioxide sensor (93), and light sensor (94) in the environmental data acquisition mechanism (69) monitor the environmental parameters of each area in real time and feed the data back to the environmental adjustment module (612), dynamically adjusting the actuators such as the electric heating plate (62), cooling chip (63), fan one (66), humidifier (67), LED light (611), solenoid valve (82), and fan two (83) to form a closed-loop control; S9. The controller (701) determines that a certain mushroom stick has completed color change (the feature comparison reaches the color change completion threshold), then controls the electric push rod (42) in the closing mechanism (4) corresponding to the conveyor belt (5) where the mushroom stick is located to move, drive the sealing plate (43) to slide along the through hole (3) to open the through hole (3), so that the conveyor belt (5) starts and transports the mushroom stick from the color change area to the budding area. S10. After the mushroom stick reaches the budding area, the controller (701) controls the electric push rod (42) of the corresponding sealing mechanism (4) to close the through hole (3), keep the left and right sides of the partition (2) isolated, and update the status information of the mushroom stick to the feature database (704). Then, repeat steps S1 to S9 to achieve fully automatic cyclic collaborative control.
