Description

Technical Field

[0001] The present invention relates to the technical field of seed and seedling cultivation, and particularly to a shelf self-propelled intelligent spray humidification device for production. Background Art

[0002] In the cultivation of edible mushroom seeds and seedlings, shelf cultivation is the mainstream mode to improve space utilization rate and achieve intensive production. This mode builds multi-layered three-dimensional cultivation shelves, which greatly increase the carrying capacity of mushroom bags in a limited space and provide a unified physical space for the growth of edible mushrooms.

[0003] At all stages of the growth of edible mushrooms, especially during the primordium differentiation and fruiting body growth stages, it is crucial to maintain a stable and uniform high-humidity environment, which directly affects the yield, appearance and quality of mushrooms. Therefore, configuring an efficient spray humidification system inside the shelf is the core link to achieve precise environmental control.

[0004] Currently, most of the spray humidification devices supporting the shelves adopt a fixed pipeline design, and their control methods mainly rely on a centralized control system based on environmental sensors or simple timing control. For example, the Chinese patent with the authorization announcement number CN109076833B provides an intelligent automatic intermittent sectional spray seedling cultivation device. This technical solution divides the seedling cultivation room into sections, installs water supply pipes in each section of the seedling cultivation room, and connects and communicates them in sequence, and connects them to a water supply pump and water supply equipment. Atomizing nozzles and solenoid valves are installed on the water supply pipes in each section of the seedling cultivation room, and the solenoid valves control the opening and closing of the atomizing nozzles. The solenoid valves in each section of the seedling cultivation room are all communicatively connected to a remote intelligent control system, so as to avoid the occurrence of insufficient water pressure and insufficient water supply.

[0005] However, such fixed spray devices still have the following deficiencies when actually applied to the cultivation of edible mushroom seeds and seedlings:

[0006] Environmental sensors usually can only collect the overall air humidity data of the shelf space, and cannot accurately sense the real-time water content of the culture medium in each independent mushroom bag or mushroom stick. Due to the differences in the position of the mushroom bags in the shelf, the intensity of mycelial respiration and metabolism, and the transpiration of the fruiting body, there is an obvious deviation between the regional environmental parameters obtained by the system and the actual water demand state of the microenvironment of a single mushroom bag, which is likely to cause problems such as insufficient humidification uniformity, local over-wetting or drying, and low water resource utilization efficiency, ultimately affecting the mushroom emergence uniformity and the quality of commercial mushrooms. Summary of the Invention

[0007] In view of the above-mentioned drawbacks of the prior art, the present invention provides a shelf self-propelled intelligent spray humidification device for production, which can effectively solve the problems existing in the prior art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] This invention provides a self-propelled intelligent spray humidification device for production, including a shelf, a ring track fixedly installed on the shelf, a spray device for moving along the track and humidifying is movably installed on the ring track, multiple mushroom bed units are fixedly installed in the shelf, each mushroom bed unit includes a fixed box and a support box for supporting mushroom bag trays, the support box is movably installed in the fixed box, and an elastic arc plate for supporting the support box is fixedly installed in the fixed box;

[0010] The fixed box is equipped with an indicator component for providing a primary visual humidity signal and a detection component for providing a secondary visual humidity signal. The spray device is fixedly installed with a control panel for simultaneously acquiring the primary and secondary visual humidity signals.

[0011] Furthermore, the indicator assembly includes a rack and a winding wheel. One end of the rack is movably connected to an elastic arc plate, and the winding wheel is movably installed in the fixed box. An indicator strip with red and green areas coated on its surface is wound around the winding wheel. The primary visual humidity signal is a visual signal that characterizes the weight change of the carrying box and its contents by the color ratio change of the indicator strip.

[0012] A gear that meshes with a rack is fixedly installed at the bottom of the take-up reel, and a slot for displaying the color of the indicator strip is provided at one end of the fixing box near the take-up reel.

[0013] Furthermore, the detection assembly includes a push rod and a fixed tube. The push rod is movably connected to the end of the elastic arc plate away from the rack. The fixed tube is fixedly installed on the fixed box. A piston rod for extracting environmental gas samples is movably installed in the fixed tube. One end of the piston rod is movably connected to the push rod.

[0014] An air chamber is fixedly installed at the top of the fixed tube. An electromagnetic block and a movable magnetic block driven by the magnetic force of the electromagnetic block are fixedly installed inside the air chamber. A humidity-sensitive resistor is fixedly installed in the fixed tube. The humidity-sensitive resistor is used to change the circuit resistance of the electromagnetic block according to the humidity of the gas inside the fixed tube.

[0015] A movable block is movably installed on one side of the air chamber, and an airbag assembly is fixedly installed in the air chamber to transmit the displacement of the movable magnetic block to the movable block. The secondary visual humidity signal is a visual signal that characterizes the humidity change of the gas sample in the fixed tube by the change in the displacement of the movable block.

[0016] Furthermore, the control panel performs image capture and data fusion calculations on the primary and secondary visual humidity signals;

[0017] When the indicator strip shows that the proportion of red area is greater than that of green, and the displacement of the moving block exceeds the first threshold, the spraying device is activated and performs a spraying operation on the current mushroom bed unit for a first predetermined duration.

[0018] When the indicator strip shows that the proportion of red area is greater than that of green, and the displacement of the moving block exceeds the second threshold but is less than the third threshold, the spraying device is activated and performs a spraying operation on the current mushroom bed unit for a second predetermined duration, wherein the second predetermined duration is greater than the first predetermined duration;

[0019] When the indicator strip shows that the proportion of red area is greater than that of green, and the displacement of the moving block exceeds the third threshold, the spraying device is activated and performs a spraying operation on the current mushroom bed unit for a third predetermined duration, wherein the third predetermined duration is greater than the second predetermined duration.

[0020] Furthermore, a reset mechanism is movably connected to both sides of the elastic arc plate. The reset mechanism is used to assist the elastic arc plate in resetting. The reset mechanism is located on both sides of the push rod. A vertical rod is movably connected to the end of the push rod away from the elastic arc plate. The top of the vertical rod is movably connected to the piston rod.

[0021] Furthermore, the reset mechanism includes a horizontal tube and a reset rod. The horizontal tube is fixedly installed at the bottom of the fixed box, and the reset rod is movably installed in the horizontal tube. One end of the reset rod is movably connected to the elastic arc plate, and a spring for resetting the reset rod is fixedly installed at the end of the reset rod away from the elastic arc plate.

[0022] Furthermore, the specific operating mode of the humidity-sensitive resistor is as follows:

[0023] When the humidity of the gas inside the fixed tube increases, the resistance of the humidity-sensitive resistor decreases, and the current in the electromagnetic block circuit increases.

[0024] The increase in current strengthens the magnetic field generated by the electromagnetic block, which in turn increases the repulsive force on the moving magnetic block. The moving magnetic block then compresses the airbag assembly, causing the airbag assembly to push the moving block to produce a corresponding displacement change.

[0025] The airbag assembly includes a drive airbag and a lifting airbag. The drive airbag is fixedly installed in a fixed tube, and one side of the drive airbag is fixedly connected to a moving magnetic block. A spring for resetting the drive airbag is fixedly installed inside the drive airbag. The lifting airbag is fixedly installed at the bottom of the moving block. The drive airbag is connected to the lifting airbag through a pipeline.

[0026] Furthermore, the control panel includes a data acquisition module, a decision analysis module, and a control execution module;

[0027] The data acquisition module acquires primary and secondary visual humidity signals from each mushroom bed unit through a visual camera. The primary visual humidity signal is the color ratio data of the indicator strip, and the secondary visual humidity signal is the displacement data of the moving block. The acquired color ratio data and displacement data are then sent to the decision analysis module.

[0028] After receiving the data, the decision analysis module compares the proportion of the red area of ​​the indicator strip with the preset color proportion threshold, and at the same time compares the displacement of the moving block with the preset displacement threshold. Based on the comparison results, it generates a spray control command and sends the control command to the control execution module.

[0029] After receiving the control command, the control execution module drives the spray head in the spraying device to perform spraying operations of the corresponding mode and duration.

[0030] Furthermore, the specific working process of the decision analysis module is as follows:

[0031] The color proportion threshold C, the first displacement threshold D1, and the second displacement threshold D2 are pre-set within the system, and D1 < D2;

[0032] When the red area of ​​the indicator strip exceeds the color proportion threshold C, a humidity anomaly signal is triggered, and the displacement of the moving block is further compared:

[0033] If the displacement of the moving block is less than or equal to the first displacement threshold D1, generate the first spray command.

[0034] If the displacement of the moving block is greater than the first displacement threshold D1 and less than or equal to the second displacement threshold D2, a second spray command is generated.

[0035] If the displacement of the moving block is greater than the second displacement threshold D2, a third spray command is generated.

[0036] The preset color percentage threshold C in the decision analysis module is 50% to 70%, the first displacement threshold D1 is 25% to 35% of the total travel of the moving block, and the second displacement threshold D2 is 55% to 65% of the total travel of the moving block.

[0037] Furthermore, the specific working process of the control execution module is as follows:

[0038] When the first spray command is received, the spray device is controlled to perform a spray operation for a first predetermined duration T1;

[0039] When a second spray command is received, the spray device is controlled to perform a spraying operation for a second predetermined duration T2, where T2 > T1;

[0040] When a third spray command is received, the spray device is controlled to perform a spray operation for a third predetermined duration T3, where T3 > T2.

[0041] The technical solution provided by this invention has the following advantages compared with the prior art:

[0042] 1. This invention is equipped with an indicator component, which converts the weight change of the mushroom bag into an intuitive visual signal of the color ratio of the indicator strip through a purely mechanical structure. This enables reliable and low-cost perception of the water requirement status of each individual mushroom bag, fundamentally overcoming the shortcomings of traditional fixed environmental monitoring that cannot reflect individual differences. It also effectively avoids water waste and uneven humidification caused by judging regional averages.

[0043] 2. The present invention is equipped with a detection component, which accurately measures the true humidity of the microenvironment gas around the mushroom bag by combining air sampling with a humidity-sensitive resistor, and uses a magnetic drive mechanism to convert the electrical signal into a mechanical displacement signal of the moving block.

[0044] This structure ensures the accuracy of humidity detection in the microenvironment of the mushroom bags, and avoids the wear and jamming problems that are prone to occur in complex linkage mechanisms under high temperature and high humidity environments through non-contact magnetic force transmission. Finally, it realizes the fusion decision of mushroom bag weight information and microenvironment humidity information through visual recognition, which significantly improves the accuracy of spray humidification and the uniformity of shelf space during the self-propelled equipment's traversal process.

[0066] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0067] The present invention will be further described below with reference to embodiments.

[0068] Example 1

[0069] Reference Figures 1-8This is the first embodiment of the present invention, which provides a self-propelled intelligent spray humidification device for production, including a shelf 1, on which a circular track 11 is fixedly installed, and a spray device 12 for moving along the track and humidifying is movably installed on the circular track 11. The spray device 12 is specifically composed of a movable base, a vision camera and a spray pipe. The movable base is movably connected to the circular track 11, and a drive motor is fixedly installed on the movable base to drive the movable base to move along the circular track 11. The vision camera and the spray pipe are both installed on the movable base. The overall structure and driving method of the spray device 12 are existing mature technologies, and its specific structure and working principle will not be described in detail here.

[0070] Multiple mushroom bed units 2 are fixedly installed in the shelf 1. Each mushroom bed unit 2 includes a fixed box 21 and a support box 22 for supporting mushroom bag trays. The support box 22 is movably installed in the fixed box 21. An elastic arc plate 23 for supporting the support box 22 is fixedly installed in the fixed box 21. The elastic arc plate 23 adopts an arched structure and is made of a metal material with good elastic recovery properties, such as spring steel or stainless steel. In its natural state, the elastic arc plate 23 is an upward arched arc. When the support box 22 is placed on it, the arc plate undergoes elastic deformation due to pressure and tends to flatten. When the support box 22 loses weight due to moisture evaporation, the elastic arc plate 23 rebounds upward and restores its arched shape under its own restoring force.

[0071] It also includes an indicator component 3, which includes a rack 31 and a take-up reel 32. One end of the rack 31 is movably connected to the elastic arc plate 23. The take-up reel 32 is movably installed in the fixed box 21. An indicator strip 33 for providing a primary visual humidity signal is wound on the take-up reel 32. A gear 34 that meshes with the rack 31 is fixedly installed at the bottom of the take-up reel 32. A through groove 35 is opened at one end of the fixed box 21 near the take-up reel 32. The indicator strip 33 is movably installed in the through groove 35. A spring is fixedly installed on the inner wall of the through groove 35. The spring is used to reset the indicator strip 33. One end of the spring is fixed to the inner wall of the through groove 35, and the other end is connected to the end of the indicator strip 33. When the take-up reel 32 rewinds, the spring is stretched. When reset is required, the restoring force of the spring helps to pull the indicator strip 33 back, so that the display returns to its initial state.

[0072] The indicator strip 33 is a two-color flexible strip, the surface of which is divided into continuous red and green areas along its length. In the initial state, the indicator strip 33 is kept taut by the winding wheel 32 and the spring. At this time, the area ratio of the red and green areas exposed in the window of the through groove 35 is a preset initial value. When the weight of the mushroom bag tray is reduced and the elastic arc plate 23 arches upward, the rack 31 moves with the arc plate and drives the gear 34 to rotate, which drives the winding wheel 32 to wind the indicator strip 33, so that the area of ​​the red area in the window of the through groove 35 increases and the green area decreases accordingly, thereby forming a visual signal that can intuitively judge the degree of water shortage.

[0073] Both sides of the elastic arc plate 23 are movably connected to a reset mechanism 7. The reset mechanism 7 is used to assist the elastic arc plate 23 in resetting. The reset mechanism 7 is located on both sides of the push rod 41. The reset mechanism 7 includes a horizontal tube 71 and a reset rod 72. The horizontal tube 71 is fixedly installed at the bottom of the fixed box 21. The reset rod 72 is movably installed in the horizontal tube 71. One end of the reset rod 72 is movably connected to the elastic arc plate 23. A spring for resetting the reset rod 72 is fixedly installed at the end of the reset rod 72 away from the elastic arc plate 23.

[0074] The specific working principle of the reset mechanism 7 is as follows:

[0075] When the weight of the carrier box 22 increases due to humidification, the elastic arc plate 23 deforms under the downward pressure. At this time, the deformation of the elastic arc plate 23 pushes the reset rod 72 to move into the horizontal tube 71 and compresses the spring. When the moisture in the carrier box 22 decreases, the restoring force of the spring pushes the reset rod 72 to extend, assisting the elastic arc plate 23 to return to its initial state.

[0076] The reset mechanism 7 is symmetrically arranged on both sides of the elastic arc plate 23. Its horizontal tube 71 is fixed to the bottom of the fixed box 21 by welding or bolts. One end of the reset rod 72 is movably connected to the elastic arc plate 23 through a hinge, and the other end extends into the horizontal tube 71 and is connected to a spring.

[0077] When the bearing box 22 presses down on the elastic arc plate 23 due to the increased weight caused by humidification, the deformation of the arc plate pushes the reset rod 72 to slide axially along the horizontal tube 71 through the hinge point, causing the spring to be compressed and store energy. When the moisture evaporates and the weight of the bearing box 22 is reduced, the spring releases energy and pushes the reset rod 72 to move in the opposite direction, providing an upward auxiliary restoring force for the elastic arc plate 23, ensuring that it quickly returns to its initial arched state. This symmetrical reset design can effectively avoid the arc plate from jamming on one side and ensure the reliability of the operation.

[0078] The present invention is equipped with an indicator component 3, which converts the weight change of the mushroom bag tray into an intuitive visual signal of the color ratio of the indicator strip 33 through a purely mechanical structure. This design overcomes the defect of electronic sensors being prone to failure in humid and corrosive environments, and realizes reliable and low-cost perception of the water requirement status of each individual mushroom bag tray, thereby avoiding misjudgment and water waste caused by traditional environmental monitoring methods.

[0079] Example 2

[0080] Reference Figures 9-12The second embodiment of the present invention provides a self-propelled intelligent spray humidification device for production, and also includes a detection component 4. The detection component 4 includes a push rod 41 and a fixed tube 42. The push rod 41 is movably connected to the end of the elastic arc plate 23 away from the rack 31. The fixed tube 42 is fixedly installed on the fixed box 21. A piston rod 43 for extracting environmental gas samples is movably installed in the fixed tube 42. One end of the piston rod 43 is movably connected to the push rod 41.

[0081] The piston rod 43 and the push rod 41 are connected as follows: the end of the push rod 41 away from the elastic arc plate 23 is movably connected to a vertical rod, and the top of the vertical rod is movably connected to the piston rod 43. That is, when the elastic arc plate 23 pushes the push rod 41 to move towards the vertical rod, the push rod 41 pushes the bottom of the vertical rod, and the top of the vertical rod pulls the piston rod 43 to move away from the fixed tube 42. When the push rod 41 pulls the bottom of the vertical rod to move, the top of the vertical rod pulls the piston rod 43 to move away from the fixed tube 42.

[0082] The detection assembly 4 also includes an air chamber 44 fixedly installed at the top of the fixed tube 42. An electromagnetic block 45 and a movable magnetic block 46 driven by the magnetic force of the electromagnetic block 45 are fixedly installed inside the air chamber 44. A humidity-sensitive resistor 47 is fixedly installed in the fixed tube 42. The humidity-sensitive resistor 47 is used to change the circuit resistance of the electromagnetic block 45 according to the humidity of the gas in the fixed tube 42. A movable block 48 for providing a secondary visual humidity signal is movably installed on one side of the air chamber 44. An air bladder assembly 6 for transmitting the displacement of the movable magnetic block 46 to the movable block 48 is fixedly installed in the air chamber 44.

[0083] The airbag assembly 6 includes a drive airbag 61 and a lifting airbag 62. The drive airbag 61 is fixedly installed in the fixed tube 42, and one side of the drive airbag 61 is fixedly connected to the movable magnetic block 46. A spring for resetting the drive airbag 61 is fixedly installed inside the drive airbag 61. The lifting airbag 62 is fixedly installed at the bottom of the movable block 48. The drive airbag 61 and the lifting airbag 62 are interconnected through pipelines.

[0084] The humidity-sensitive resistor 47 is an impedance-type humidity sensing element. Its resistance decreases exponentially as the ambient humidity increases. This resistor is connected in series in the power supply circuit of the electromagnetic block 45. When the humidity of the gas inside the fixed tube 42 changes, the resistance of the humidity-sensitive resistor 47 changes accordingly, thereby linearly adjusting the current intensity flowing through the electromagnetic block 45.

[0085] The electromagnetic block 45 adopts a DC excitation coil structure, and the magnetic field strength generated by it is proportional to the current. It drives the moving magnetic block 46 to move through magnetic coupling.

[0086] The humidity-sensitive resistor 47 works as follows: when the humidity of the gas inside the fixed tube 42 increases, the resistance of the humidity-sensitive resistor 47 decreases, the current in the circuit of the electromagnetic block 45 increases, the increased current strengthens the magnetic field generated by the electromagnetic block 45, and increases the repulsive force on the moving magnetic block 46. The moving magnetic block 46 squeezes the airbag assembly 6, causing the airbag assembly 6 to push the moving block 48 to produce a corresponding displacement change.

[0087] It should be noted that in actual use, during the moisture loss process of a single mushroom bed unit 2, the weight of the support box 22 gradually decreases, and the elastic arc plate 23 deforms accordingly. Through the linkage mechanism between the push rod 41 and the vertical rod, the piston rod 43 is driven to be smoothly pulled outward in the fixed tube 42. This extraction process is continuous and coordinated with the moisture evaporation rate of the mushroom bag tray. The movement of the piston rod 43 creates a negative pressure in the fixed tube 42, which causes the external ambient gas to be continuously drawn in through the one-way air inlet valve on one side of the fixed tube 42.

[0088] The bottom of the fixed tube 42 is provided with an air outlet pipe, and a one-way air outlet valve is also fixedly installed in the air outlet pipe. The function of the one-way valve is to control the direction of gas flow. When humidification is completed, the elastic arc plate 23 is reset, and when the piston rod 43 moves towards the fixed tube 42, the one-way air inlet valve is closed and the one-way air outlet valve is opened. Under the squeezing action of the piston rod 43, the gas is discharged through the air outlet pipe.

[0089] Since gas sampling is carried out gradually with the deformation of the elastic arc plate 23, the gas sample finally obtained in the fixed tube 42 represents the cumulative effect of ambient humidity over a period of time from the start of this water demand cycle to the triggering of spray. The inhaled gas sample flows through the humidity-sensitive resistor 47 sensing area on the inner wall of the fixed tube 42 to complete the humidity measurement. The entire gas extraction process terminates when the elastic arc plate 23 reaches the maximum deformation position.

[0090] The displacement distance of the moving block 48 is negatively correlated with the ambient humidity. When the overall ambient humidity is low during the sampling period, the gas sample in the fixed tube 42 is dry, the resistance of the humidity-sensitive resistor 47 is large, the current of the electromagnetic block 45 is weak, and the displacement distance of the moving block 48 decreases. Conversely, the displacement increases. This displacement directly reflects the continuous impact of the degree of dryness of the environment on water evaporation during the water shortage process.

[0091] As the humidity inside the fixed tube 42 changes, the resistance of the humidity-sensitive resistor 47 changes accordingly, causing the current intensity of the electromagnetic block 45 to change. This, in turn, drives the moving magnetic block 46 to move through magnetic force. The airbag assembly 6 forms a closed pneumatic transmission system. When the moving magnetic block 46 moves, it squeezes and drives the airbag 61. The internal air pressure is transmitted to the lifting airbag 62 through the sealed pipeline, which pushes the moving block 48 to move linearly, thus achieving non-contact displacement transmission.

[0092] A control panel 5 is fixedly installed on the spraying device 12. It is used to simultaneously acquire primary and secondary visual humidity signals. The control panel 5 performs image capture and data fusion calculation on the color ratio of the indicator strip 33 and the position of the moving block 48, and executes the spraying operation according to the following rules:

[0093] When the indicator band 33 shows that the proportion of red area is greater than that of green, and the displacement of the moving block 48 exceeds the first threshold, a spraying operation of the first predetermined duration is performed.

[0094] When the indicator band 33 shows that the proportion of red area is greater than that of green, and the displacement of the moving block 48 exceeds the second threshold but is less than the third threshold, a spraying operation of the second predetermined duration is performed.

[0095] When the indicator band 33 shows that the proportion of red area is greater than that of green, and the displacement of the moving block 48 exceeds the third threshold, a spraying operation of the third predetermined duration is performed.

[0096] The second scheduled duration is longer than the first scheduled duration, and the third scheduled duration is longer than the second scheduled duration.

[0097] The control panel 5 includes a data acquisition module, a decision analysis module, and a control execution module. The data acquisition module acquires the color ratio data of the indicator strip 33 and the displacement data of the moving block 48 through the vision camera, and sends the data to the decision analysis module.

[0098] The working principle and process of the vision camera are as follows: When the spraying device 12 moves to the detection position of the mushroom bed unit 2, the vision camera starts image acquisition under the trigger of the control signal. First, it focuses on the window of the through slot 35 of the indicator strip 33 and the indicator area of ​​the moving block 48 to acquire color images simultaneously. Then, the RGB image is converted into the HSV color space to separate the chromaticity and luminance information. The display area of ​​the indicator strip 33 and the outline of the moving block 48 are accurately located through the preset visual marks. Then, the pixel-level analysis of the indicator strip 33 area is performed to count the number ratio of red and green pixels. At the same time, the pixel displacement of the moving block 48 relative to the reference position is calculated based on the edge detection algorithm and converted into the actual physical displacement through the calibration coefficient. Finally, the calculated color ratio data and displacement data are encapsulated and transmitted to the decision analysis module to complete the non-contact vision inspection process.

[0099] After receiving the data, the decision analysis module compares the proportion of red area with the preset color proportion threshold C, and simultaneously compares the displacement of moving block 48 with preset displacement thresholds D1 and D2 (D1 < D2). Based on the comparison results, it generates spray control commands:

[0100] When the proportion of red area is greater than C, further compare the displacement of moving block 48:

[0101] If the displacement is less than or equal to D1, generate the first spray command;

[0102] If D1 < displacement ≤ D2, generate a second spray command;

[0103] If the displacement is greater than D2, generate a third spray command.

[0104] The control execution module drives the spray head to perform spraying operations of corresponding durations according to the received instructions: the first spray instruction corresponds to a duration of T1, the second spray instruction corresponds to a duration of T2 (T2>T1), and the third spray instruction corresponds to a duration of T3 (T3>T2).

[0105] Furthermore, the preset parameter ranges in the decision analysis module are: color proportion threshold C is 50% to 70%, first displacement threshold D1 is 25% to 35% of the total travel of moving block 48, and second displacement threshold D2 is 55% to 65% of the total travel of moving block 48.

[0106] The threshold parameter is set based on the principle of quantitative balance between the physiological needs and environmental impact of edible fungi cultivation. The color proportion threshold C is set to 50% to 70%. This range ensures that the system responds in a timely manner when there are obvious signs of water shortage in the mushroom bag tray, that is, when the red proportion exceeds half, avoiding response delays caused by excessively high thresholds or misjudgments caused by excessively low thresholds.

[0107] The division of displacement thresholds D1 (25%–35%) and D2 (55%–65%) is based on the physical characteristics of the moving block 48 across its full range.

[0108] When the displacement is ≤ D1, it indicates that the environment is significantly dry during the sampling period, and spraying needs to be intensified.

[0109] When the displacement is in the range of D1-D2, it indicates that the ambient humidity is moderate, and standard compensation is used.

[0110] When the displacement is greater than D2, it indicates that the environment is humid, and only basic spraying is required.

[0111] This segmented control strategy directly quantifies the continuous impact of environmental humidity on the evaporation of moisture from the mushroom bag trays by measuring mechanical displacement, thus achieving a precise match between water demand and humidification.

[0112] It should be noted that the working time control mechanism of the spray device 12 is as follows: the control system of the spray device 12 has a preset time threshold parameter. When the continuous running time of the system reaches the preset time threshold, the inspection start signal will be automatically triggered. At this time, the drive motor starts and drives the moving seat to move along the circular track 11, so that the spray device 12 enters the periodic inspection working state.

[0113] During the inspection, when the mobile unit carrying the vision camera moves to the preset detection position directly above a single mushroom bed unit 2, the mobile unit stops moving. The vision camera then acquires and identifies the color ratio of the indicator strip 33 and the displacement of the moving block 48 below, and transmits the identification results to the decision analysis module in real time for data fusion calculation. According to the spray command generated by the calculation, the control execution module controls the spray head to perform a fixed-point spraying operation for the corresponding duration. After the operation at this station is completed, the mobile unit continues to move to the next mushroom bed unit 2 position and repeats the above detection and operation process until the inspection and humidification operation of all mushroom bed units 2 is completed.

[0114] This automatic inspection mechanism, triggered by a time threshold, ensures that the humidity of the edible fungi processing environment is monitored and regulated regularly and comprehensively, effectively avoiding local environmental imbalances caused by omissions in single-point monitoring or response delays.

[0115] In summary, the present invention has a detection component 4, which accurately measures the actual humidity of the microenvironment gas around the mushroom bag tray by combining air sampling with a humidity-sensitive resistor 47, and uses a magnetic drive mechanism to convert the electrical signal into a mechanical displacement signal of the moving block 48.

[0116] This structure ensures the accuracy of environmental humidity detection, avoids wear and jamming problems of complex mechanical linkages through non-contact magnetic force transmission, and finally realizes the fusion decision of disk weight information and environmental humidity information through visual recognition, which significantly improves the accuracy and uniformity of spray humidification.

[0117] The working principle of this invention is as follows:

[0118] First, when the system reaches the preset time threshold or receives the start command, the spraying device 12 starts to move along the circular track 11 and passes over each mushroom bed unit 2 in sequence. While moving, the vision camera simultaneously collects two visual signals: the color ratio of the indicator strip 33 and the displacement of the moving block 48 of the mushroom bed unit 2, and transmits the data to the decision analysis module.

[0119] Furthermore, the decision analysis module fuses and judges the signals. When the proportion of the red area of ​​the indicator band 33 exceeds the set threshold, it is determined that the mushroom bag tray is in a water shortage state. Then, according to the threshold range of the displacement of the moving block 48, a spray command with a corresponding duration is generated. That is, the smaller the displacement, the drier the environment, and the longer the spray duration. The larger the displacement, the more humid the environment, and the shorter the spray duration accordingly.

[0120] Furthermore, the control execution module drives the spray head to perform quantitative spraying according to the instructions. After humidification is completed, the spray device 12 continues to inspect the next station. The weight of the humidified mushroom bag tray increases, driving the elastic arc plate 23 to press down and reset. The reset mechanism 7 and the piston rod 43 work together to discharge the detected gas in the fixed tube 42. The entire system returns to the initial state and waits for the next cycle of detection.

[0121] This invention automatically completes water demand judgment and environmental humidity detection through mechanical structure, and combines visual recognition and intelligent decision-making to achieve independent, precise and adaptive humidification for each mushroom bed unit 2, effectively overcoming the problems of water waste and uneven humidification in traditional methods.
