Description

Technical Field

[0001] This utility model relates to the field of mushroom cultivation technology, and in particular to an automatic drying control system for a mushroom shiitake mushroom growing greenhouse. Background Technology

[0002] Currently, most shiitake mushrooms are grown in greenhouses owned by farmers. Every day, staff need to air out the greenhouse (by hand or electric crank to roll up the heat-insulating and sun-shading side) to ensure the mushrooms have the necessary oxygen and light for growth, while also reducing the growth of unwanted bacteria and insects inside the greenhouse and improving the quality of the mushrooms.

[0003] The current management of shiitake mushroom greenhouses relies on manual operation, which has significant drawbacks: each operator can manage a maximum of 10 greenhouses, requiring frequent inspections and manual adjustment of the roller shutters (hand-cranked or electric), resulting in high labor costs; furthermore, in the event of sudden heavy rain, strong winds, or other weather conditions, the roller shutters may not be closed in time, leading to rain damage and a decline in the quality of the shiitake mushrooms, thus affecting the quality of the mushrooms. Summary of the Invention

[0004] To address the aforementioned problems, the purpose of this utility model is to provide an automatic drying control system for mushroom cultivation greenhouses, which integrates weather forecasts to automatically control the opening and closing of the curtains.

[0005] An automatic drying shed control system for edible mushroom (shiitake) growing greenhouses includes: The greenhouse body includes the frame, and several layers of roller blinds are installed on the top of the frame from the inside out, each layer of roller blinds can be rolled up separately; The winding mechanism is set up one-to-one with the roller shutter, driving each roller shutter to close or open at the target angle; The meteorological monitoring unit is used to collect forecast weather data for a preset time period in real time; The control system is connected to the meteorological monitoring unit and the winding mechanism respectively. The control system controls the operation of the winding mechanism in combination with the weather data returned by the meteorological monitoring unit.

[0006] Preferably, it includes three layers of roller blinds, which are, from the inside out, a shade net, a nylon film, and an insulating blanket.

[0007] Preferably, the winding mechanism includes a roller shutter motor connected to each layer of roller shutter, and the target angle of each roller shutter motor is set independently.

[0008] Preferably, the winding mechanism includes a roller and a support rod, the support rod supporting the roller from both sides, and the lower end of the support rod is hinged to the ground; the end of the roller blind is wound around the roller, and the roller blind motor drives the roller to rotate.

[0009] Preferably, each layer of the roller blind is equipped with two roller blind motors, for a total of six motors, and each motor is connected to an angle sensor; the angle sensor is communicatively connected to the control system and is used to detect the opening angle of the roller blind.

[0010] Preferably, the control system is used to set the drying period and control the operation of the roller shutter motor in conjunction with the predicted weather data during the drying period.

[0011] Preferably, the control system includes a human-machine interaction platform, which includes a drying time setting module and a target angle setting module for each layer of the roller shutter.

[0012] Preferably, the human-computer interaction platform includes a notification module, which is used to send a reminder message to a designated user when severe weather is detected during a set time period in the shade.

[0013] This application, by adopting the above-mentioned solution, has the following effects: 1. Whether it is a shiitake mushroom grower or a shiitake mushroom factory, adopting this system can greatly reduce labor costs. (In the traditional model, one person can manage a maximum of 10 greenhouses, and the person needs to conduct regular inspections and check the weather forecast to take precautions. However, this system allows one person to manage an unlimited number of shiitake mushroom greenhouses.) 2. Integrate meteorological station data to predict future weather conditions, make advance risk responses, and eliminate all losses caused by natural weather (traditional processes are prone to problems such as the greenhouse curtains not closing in time during sudden rain, resulting in shiitake mushrooms getting wet and reducing quality; strong winds can also cause the roof to be blown off, etc.). 3. The drying shed angle is digitalized, which is more reliable than the traditional method that relies on the operator's sense of touch, and can more effectively ensure the stability of the mushroom quality.

[0016] Greenhouse body 1, shade net 11, nylon film 12, thermal insulation quilt 13, roller shutter motor 21, meteorological monitoring unit 3, control system 4. Detailed Implementation

[0017] The embodiments of this utility model are described in detail below. Example 1:

[0018] An automatic drying control system for shiitake mushroom growing greenhouses, such as Figure 1 As shown, it includes: The greenhouse body 1 includes a frame with several layers of roller shutters arranged sequentially from the inside out. Each layer of roller shutters can be rolled up and down. Each layer of roller shutters has a closed state and an open state. When fully closed, each layer of roller shutters can completely cover the top surface of the frame, preventing the crops inside the greenhouse from being exposed. When the roller shutters are open, the crops inside the greenhouse can be exposed. The frame structure in this embodiment can be a conventional mushroom cultivation greenhouse, without any restrictions. In this embodiment, several layers of roller shutters are set according to different functional requirements such as heat preservation, sun protection, and light transmission. The material of each layer of roller shutters is set according to the functions required.

[0019] The winding mechanism is set up one-to-one with each layer of the roller blind, driving each layer of roller blind to close or open at the target angle; the winding mechanism includes a roller blind motor 21, which can realize the automatic opening and closing of the roller blind by controlling the roller blind motor 21.

[0020] A meteorological monitoring unit 3 is installed on one side of the greenhouse body 1 to collect real-time forecast weather data for the location of the greenhouse body 1. In a specific embodiment, the meteorological monitoring unit 3 can directly use existing equipment and be installed on one side of the greenhouse body 1 to monitor local meteorological data; in other optional embodiments, data from a local meteorological station can also be directly obtained. In this embodiment, the meteorological monitoring unit 3 is used to acquire forecast weather data for the next 12 hours and update the forecast weather data in real time. The expected weather data includes weather conditions and wind speed, as well as other weather data related to edible mushroom cultivation.

[0021] The control system 4 is connected to the meteorological monitoring unit 3 and the winding mechanism. The control system 4 controls the operation of the winding mechanism based on the predicted weather data returned by the meteorological monitoring unit 3. The control system 4 presets the daily drying time period and the target angle of each layer of the roller shutter, and dynamically adjusts the state of the roller shutter based on the data returned by the meteorological monitoring unit 3. Specifically, if it is predicted that there will be no rain, strong wind or other severe weather during the drying time period, it controls the roller shutter motor 21 to open the corresponding roller shutter to the target angle for drying; if it is predicted that there will be rain or strong wind, it keeps the roller shutter closed; or it terminates the drying in advance and closes the roller shutter.

[0022] The above solution enables unattended automated operation by controlling the winding mechanism through control system 4. A single person can manage multiple greenhouses through a centralized control platform, significantly reducing labor costs. Controlling the greenhouses based on forecast weather data from meteorological monitoring unit 3 allows for proactive responses to weather conditions, avoiding problems such as mushroom spoilage due to rain and greenhouse roof damage caused by response delays in traditional methods.

[0023] In this embodiment, three layers of roller blinds are included: a shade net 11, a nylon film 12, and an insulation blanket 13, arranged sequentially from the inside out, to meet the needs of shading, light transmission, and heat preservation. All three layers of roller blinds can be closed or opened to a target angle by a winding mechanism. The winding mechanism includes roller blind motors 21 connected to each layer of roller blinds, and the target angle of each motor 21 is independently set. The winding mechanism in this embodiment includes a roller shaft and support rods. The support rods support the roller shaft from both sides, and the lower end of the support rods is hinged to the ground. The end of the roller blind is wound around the roller shaft, and the roller blind motors 21 drive the roller shaft to rotate. For a single layer of roller blind, the end of the blind is wound around the roller shaft, which is driven to rotate by the roller blind motors 21. At this time, the roller shaft winds or unwinds the roller blind, causing the support rods to rotate around the hinge point at its lower end. The support rods are located on both sides of the greenhouse body 1 along its length.

[0024] In this embodiment, each layer of the roller blind is equipped with two roller blind motors 21, for a total of six motors. Each roller blind motor 21 is connected to an angle sensor. The angle sensor is communicatively connected to the control system 4 and is used to detect the opening angle of the roller blind. In this embodiment, the center point of the greenhouse body 1 is O, and the angle between the line a connecting the roller shaft and the center point O and the ground is α. α indicates the opening angle of the roller blind. When α=0°, the roller blind is closed; when α=90°, the roller shaft is at the top of the greenhouse. At 0°, the roller blind is in a closed state. When the angle is greater than 0°, the roller blind opens from the bottom to a certain angle for drying. In this embodiment, each layer of the roller blind is equipped with two roller blind motors 21 and two roller shafts. The left and right ends of the roller blind are wound on the two roller shafts respectively. The two roller shafts are each controlled by one roller blind motor 21. When both roller shafts move to the top of the greenhouse, the roller blind is fully opened. The opening direction of the roller blind can be controlled by the roller blind motors 21 on both sides.

[0025] In this embodiment, the target angle of each roller blind motor 21 is set independently. For example, during the drying period, the target angle of the left half of the thermal insulation quilt 13 roller blind motor 21 is 90 degrees, the target angle of the nylon film 12-layer roller blind motor 21 is 70 degrees, and the target angle of the shade net 11-layer roller blind motor 21 is 45 degrees. The right half of each layer is the same as the left half. The target angle here is α as mentioned above.

[0026] The control system 4 is used to set the drying period and, based on predicted weather data, control the operation of the roller shutter motor 21 during that period. Specifically, it controls whether the rolling mechanism opens the roller shutter according to the predicted weather conditions during the drying period.

[0027] For ease of management, the control system 4 includes a human-machine interface platform, which includes a drying time setting module and a target angle setting module for each layer of roller shutters. This allows users to customize the drying time and the target angle of each roller shutter motor 21. The human-machine interface platform also includes a notification module, used to send reminder messages to designated users when inclement weather is detected during the set drying time period. For example, the reminder message could ask the user whether to change the drying time.

[0028] The above system works as follows: The six roller shutter motors 21 in the mushroom greenhouse are in a 0-degree off state by default. The control system 4 is set to air the greenhouse from 16:00 to 16:30 every day. This time can be set according to different seasons and the needs of technicians. The roller shutter motors 211 and 2 are set to 90 degrees, the roller shutter motors 211 and 2 of the nylon film 12 are set to 70 degrees, and the roller shutter motors 211 and 2 of the shade net 11 are set to 45 degrees. At the same time, the weather station will transmit the predicted weather conditions and wind force for the next 12 hours to the control system 4. If the control system 4 detects rain or strong winds during the set time for the shaded area, it will remind the management personnel through the platform information whether to change the shaded area time. If the time is not changed, the 6 roller shutter motors 21 of the shaded area will not operate after the time point. If the weather is good during the set drying time, the six roller shutter motors 21 will move to the previously set angles after the drying time (16:00). After 16:30, the six roller shutter motors 21 will automatically move to 0 degrees (default state). If the weather station initially predicts good weather within the set drying time, the roller shutter motor 21 will move to the corresponding angle as set. However, if the weather station updates the data and predicts rain in 10 minutes, the control system 4 will automatically issue a command to return the 6 roller shutter motors 21 to their original default state.

[0029] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
