Description

Technical Field

[0001] The present invention relates to the technical field of intelligent fungus cultivation, and in particular to an intelligent movable fungus production cabin and a control method. Background Art

[0002] For a long time, mushroom cultivation has relied on traditional production methods, limited by natural environmental conditions such as temperature, humidity, and light. This has resulted in low-level production technology, making year-round production impossible and ensuring both yield and quality. Utilizing limited human and natural resources to achieve sustainable agricultural development is not only a pressing issue for current agricultural production but also a key direction for future agricultural development.

[0003] The emerging field of facility agriculture is an agricultural production method that uses engineering techniques to create a relatively controlled environment. Its goal is to provide optimal growing conditions for crops, thereby improving agricultural production efficiency and increasing production and income. Based on different investment options and corresponding technological applications, common facility farming practices can be categorized into various implementation methods, including traditional ventilated plastic greenhouses, semi-enclosed glass greenhouses, and fully controlled artificial plant factories.

[0004] Plant factories face significant initial investment costs, high energy consumption for equipment operation, difficulty in securing land, and the immobility of existing facilities. Plastic greenhouses also suffer from low automation levels, reliance on manual labor, small production scales, and difficulty regulating temperature and humidity. In practice, limitations have also gradually emerged, such as uneven air supply or excessive air speeds, uneven temperature and humidity control, and poorly controlled carbon dioxide and oxygen concentrations, all of which affect microbial growth and yield.

[0005] Moreover, due to the uneven technical levels of actual growers, it is difficult to carry out quality control, resulting in uneven quality of fungi.

[0006] The present invention provides an intelligent movable fungus production chamber and control method. Based on the optimal growth parameters of the entire life cycle of fungi, combined with green new energy technologies, heat recovery technologies, data acquisition, analysis and control technologies, it simulates the optimal fungus growth conditions and minimizes energy consumption to create a movable integrated intelligent fungus planting and growth chamber solution. Summary of the Invention

[0007] The present invention aims to solve the problems of uneven temperature, humidity and air supply control in existing growth chambers. At the same time, since the cultivation technology relies on manual labor, it is difficult to control quality, resulting in uneven mushroom quality and yield. The present invention provides an intelligent movable mushroom production chamber and a control method.

[0008] A smart, movable fungus production chamber, comprising a growth chamber and an equipment chamber; an air parameter measurement sensor unit is arranged on a cultivation rack within the growth chamber; micro-ducts are evenly arranged within the walls of the growth chamber; air supply ducts are arranged on both sides of the walls, and a return air duct is arranged on the top;

[0009] The equipment cabin is provided with a kinetic energy host and an air processing unit;

[0010] The air supply duct is connected to the air outlet of the air handler, and the return air duct is connected to the return air outlet of the air handler;

[0011] The kinetic energy host is connected to the micro-pipeline through a micro-pipeline delivery pipeline.

[0012] The present invention also provides a control method for a smart movable fungus production chamber, which is used to control the temperature, humidity, and CO2 concentration of the smart movable fungus production chamber. The specific control process is as follows:

[0013] Temperature control;

[0014] Input the target temperature, target humidity and target CO2 concentration of the production chamber on the external display control screen;

[0015] Based on the difference between the indoor dry-bulb and wet-bulb sensor temperatures and the target temperature, the kinetic energy host determines whether to adopt cooling or heating mode for the production cabin. The temperature adjustment method is determined based on the indoor and outdoor dry-bulb and wet-bulb sensor temperatures, as well as the target temperature:

[0016] When the target temperature is lower than the indoor dry-bulb sensor temperature, and the indoor dry-bulb sensor temperature is lower than the outdoor dry-bulb sensor temperature, the kinetic energy host controls the cooling mode;

[0017] When the target temperature is lower than the indoor dry-bulb sensor temperature and the indoor dry-bulb sensor temperature is higher than the outdoor dry-bulb sensor temperature, the fresh air duct is used to achieve cooling;

[0018] Humidity control;

[0019] The kinetic energy host is used to determine whether to start the humidification system according to the humidity of the indoor dry-bulb and wet-bulb sensors and the target humidity;

[0020] CO2 concentration control;

[0021] According to the CO2 sensor's concentration and the target CO2 concentration, it is determined whether to adopt ventilation to adjust the CO2 concentration. When ventilation is adopted, the kinetic energy host controls the opening of the fresh air valve and the exhaust valve, closes the air mixing valve, and then starts the exhaust fan and the supply fan to deliver fresh air into the growth chamber while exhausting the indoor air.

[0022] Heat recovery equipment is used to preheat or precool the fresh air using indoor exhaust air, and the opening degree of the fresh air valve, exhaust valve and mixed air valve is adjusted according to the value of the supply air temperature sensor.

[0023] Beneficial effects of the present invention:

[0024] The intelligent movable fungus production chamber described in the present invention realizes precise temperature and humidity regulation and gas concentration control; and realizes real-time data monitoring, timely automatic alarm and convenient remote control.

[0025] The intelligent mobile fungus production cabin described in this invention is a dual-system cabin: a wind and temperature control system and a micro-pipeline heat radiation temperature control system. It uses an advanced three-dimensional heat recovery system to reduce energy waste.

[0026] The present invention combines a hardware system with an intelligent control system and remote data monitoring to intelligently control fungus production through the input of optimal growth parameters of the fungus production cycle, thereby avoiding fungus quality problems caused by uneven technical levels of growers and standardizing fungus cultivation.

[0027] Utilizing the intelligent, mobile fungus production chamber described in this invention, actual trials have cultivated high-value-added fungi such as King Oyster Mushroom, White Oyster Mushroom, and Morchella. This provides an optimal growth environment for the fungi, enabling them to maintain healthy growth in all seasons, unaffected by extreme weather conditions such as high temperatures, rain, snow, cold snaps, droughts, and floods. This enables continuous, green production year-round, significantly increasing fungus yields. Thanks to precise environmental control and scientific cultivation management, the fungus growth process is more stable, fully realizing its growth potential and thus improving its quality.

[0028] The intelligent movable fungus production cabin described in the present invention has a movable feature that makes its land use flexible and applicable to wastelands, mountains, deserts, villages, fields, courtyards, islands, cargo ships, etc. It is not restricted by terrain and land properties (unlike traditional planting methods and plant factories, which occupy a large area and are immovable). It can make full use of various idle land resources for fungus cultivation, providing more possibilities and options for the development of the fungus industry.

[0029] The intelligent movable fungus production cabin described in the present invention can grow a variety of fungus varieties, meet different market demands and growers' business choices, and provide support for the diversified development of the fungus industry.

[0030] The intelligent movable fungus production cabin described in the present invention is a smart fungus production cabin covering an area of about 40 square meters. It can grow varieties with high economic benefits and can generate an annual profit of about 150,000 to 300,000 yuan, with a high return on investment. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Specific implementation method 1. Combination Figures 1 to 4 This embodiment describes a smart movable fungus production chamber, the main chamber of which is mainly composed of a growth chamber 1 and an equipment chamber 2;

[0037] Air supply ducts 3 (with holes uniformly opened on the surface of the ducts for air supply) are provided on both sides of the growth chamber 1 and connected to the air outlet of the air processing unit 18; a return air duct 4 is arranged in the center of the top of the growth chamber 1 and connected to the return air outlet of the air processing unit 18 for uniform air return; growth lighting strips 6 and a humidification system 10 are arranged on both sides of the return air duct 4; the humidification system 10 is connected to the humidification equipment 17 in the equipment compartment 2;

[0038] Cultivation racks 5 are evenly arranged inside the growth chamber 1; CO2 sensors 7, indoor dry-bulb and wet-bulb sensors 8, and wind speed sensors 9 are installed on the cultivation racks 5 for measuring air parameters in the growth chamber 1; cameras 16 are located on both sides of the growth chamber 1; and micro-pipes 30 are evenly arranged in the four walls of the entire growth chamber 1 for temperature regulation.

[0039] The equipment cabin 2 is located at the end of the production cabin and is isolated from the growth cabin 1. The lower part is the kinetic energy host 19 (including the control and data processing system); the kinetic energy host 19 is connected to the micro-pipeline 30 through the micro-pipeline delivery pipeline 29, and is connected to the external unit heat exchange module 20 through the refrigerant pipeline and is connected to the double condenser 25 in the air processing unit 18 through the refrigerant pipeline; the kinetic energy host 19 (including the control and data processing system) can adopt a heat pump host.

[0040] like Figure 4 As shown, the air handler 18 is provided with the following components arranged in order according to the air flow direction: an exhaust fan 21, an air mixing valve 24, a filter device 23, a blower 22, and a dual condenser 25; the air handler 18 is connected to the top heat recovery device 26 through the fresh air duct 13 and the exhaust duct 12 for heat exchange between fresh air and exhaust air; the fresh air valve 15, the exhaust valve 14, and the air mixing valve 24 cooperate with each other to adjust the fresh and exhaust air volumes;

[0041] A filtering device 23 is installed on the air inlet side of the exhaust fan 21 and the supply fan 22, the supply air duct 3 is connected to the air outlet of the supply fan 22 in the air handler 18, and the return air duct 4 is connected to the air inlet of the exhaust fan 21 in the air handler 18; a supply air temperature sensor 17 is installed in the supply air duct 3, and a return air temperature sensor 28 is installed in the return air duct 4; an outdoor temperature sensor 11 and an external display control screen 31 are installed outside the equipment compartment 2.

[0042] In this embodiment, the growth chamber 1 and the equipment chamber 2 are separately arranged and do not affect each other. When the system in the equipment chamber is running, the air parameters in the growth chamber 1 are adjusted according to the feedback parameters of the indoor CO2 sensor 7, the indoor dry-bulb sensor 8, and the wind speed sensor 9.

[0043] The intelligent, mobile fungus production chamber described in this embodiment enables full, fully automated intelligent control of the entire process. Based on the optimal growth parameters of the fungus production cycle, intelligent control parameters for the entire fungus cultivation process (such as temperature, humidity, and CO2 parameters on the first day, temperature, humidity, and CO2 parameters on the second day, and so on, on the nth day, etc.) are set.

[0044] In this embodiment, temperature regulation is achieved by using two systems: wind,temperature regulation system and micro-pipeline heat radiation temperature regulation system;

[0045] The air supply duct 3 is arranged in three layers as an air and temperature regulating system, and the air supply surface is evenly opened, so that the air supply is uniform and the wind speed is low, reducing the impact of wind on fungus production.

[0046] The micro-pipeline 30 (capillary network) serves as a micro-pipeline heat radiation temperature regulation system and is arranged in the four walls of the growth chamber 1. The micro-pipeline heat radiation temperature regulation system can avoid the impact of direct air blowing on fungus cultivation, and the temperature fluctuation in the growth chamber 1 is small when the system is in operation.

[0047] In this embodiment, there are two major energy consumptions in the fungus cultivation process: one is the energy consumption in the temperature adjustment process, and the other is the energy waste when adjusting the CO2 concentration.

[0048] Regarding energy consumption during temperature regulation: When the growth chamber 1 needs to be cooled, the indoor and outdoor dry-bulb sensors 8 and 11 determine whether to use fresh air cooling or unit operation. When using fresh air cooling, the kinetic energy host (including the control and data processing system) 19 controls the opening of the fresh air valve 15 and exhaust valve 14, partially closing the mixing valve 24, and then activating the exhaust fan 21 and supply fan 22. Based on the reading from the supply air temperature sensor 27, the opening of the fresh air valve 15, exhaust valve 14, and mixing valve 24 is adjusted to prevent excessive temperature fluctuations that could affect the growth of the fungus. If air exchange alone cannot achieve the target temperature, air exchange is initiated. Once the internal and external temperatures are roughly aligned, the equipment is activated for cooling. The same principle applies when the growth chamber needs to be heated.

[0049] Regarding energy waste during CO2 concentration adjustment: the production cabin uses advanced heat recovery equipment 26 (three-dimensional heat pipe heat recovery equipment), which can effectively reduce energy loss during ventilation.

[0050] Specific embodiment 2: This embodiment is a control method for a smart movable fungus production cabin described in specific embodiment 1. The implementation process of this method is as follows:

[0051] The required parameters (target temperature, target humidity, target CO2 concentration parameters) are inputted on the external display control screen 31 of the production chamber 1, and the kinetic energy host (including the control and data processing system) 19 performs real-time automatic control according to the real-time parameters.

[0052] 1. Temperature control of growth chamber 1:

[0053] The kinetic energy host (including the control and data processing system) 19 determines whether the system adopts the cooling mode or the heating mode according to the temperature parameters of the indoor dry-bulb and wet-bulb sensors 8 and the target temperature parameters;

[0054] Determine the temperature adjustment method based on the temperature parameters of the indoor dry-bulb and wet-bulb sensors 8, the outdoor dry-bulb and wet-bulb sensors 11, and the target temperature parameters:

[0055] When the target temperature is lower than the temperature parameter of the indoor dry-bulb sensor 8 (cooling is required), and the temperature parameter of the indoor dry-bulb sensor 8 is lower than the temperature parameter of the outdoor dry-bulb sensor 11, the kinetic energy host (including the control and data processing system) 19 controls the operation of the corresponding equipment to perform forced cooling (forced cooling can be achieved by using wind, temperature control system or micro-pipeline thermal radiation temperature control system).

[0056] When the target temperature is lower than the temperature parameter of the indoor dry-bulb sensor 8 and higher than the temperature parameter of the outdoor dry-bulb sensor 11, fresh air cooling is implemented to reduce energy consumption. When fresh air cooling is implemented, the kinetic energy host (including the control and data processing system) 19, i.e., the heat pump host, controls the opening of the fresh air valve 15 and the exhaust air valve 14. After partially closing the air mixing valve 24, the exhaust fan 21 and the supply fan 22 are activated to lower the temperature inside the growth chamber 1 by supplying fresh air. The opening degree of the fresh air valve 15, the exhaust air valve 14, and the air mixing valve 24 are adjusted based on the value of the air supply temperature sensor 27 to prevent excessive temperature fluctuations that could affect the growth of the fungi. If air exchange alone cannot achieve the target temperature, air exchange is implemented first. When the internal and external temperatures are roughly equal, the equipment is activated for cooling.

[0057] The same applies when the temperature of the growth chamber 1 needs to be increased after comparing the temperature parameters of the indoor dry-bulb and wet-bulb sensor 8, the temperature parameters of the outdoor dry-bulb and wet-bulb sensor 11, and the target temperature parameters.

[0058] 2. Humidity control of growth chamber 1:

[0059] The kinetic energy host (including the control and data processing system) 19 determines whether to start the humidification system according to the humidity parameters of the indoor dry-bulb and wet-bulb sensors 8 and the target humidity parameters;

[0060] 3.CO2 concentration control;

[0061] The kinetic energy host (including the control and data processing system) 19 determines whether to initiate air exchange to adjust the CO2 concentration based on the CO2 sensor's concentration parameters and the target CO2 concentration parameters. When air exchange is initiated, the heat pump host (including the control and data processing system) 19 controls the opening of the fresh air valve 15 and the exhaust valve 14, partially closes the mixing valve 24, and activates the exhaust fan 21 and the supply fan 22, delivering fresh air into the growth chamber 1 while exhausting some indoor air. Advanced heat recovery equipment 26 is employed to preheat (precool) the fresh air using indoor exhaust air, reducing heat loss and thus saving energy. During the air exchange process, the opening of the fresh air valve 15, the exhaust valve 14, and the mixing valve 24 is adjusted based on the value of the supply air temperature sensor 27 to prevent excessive temperature fluctuations that could affect the growth of the fungus. If necessary, equipment is activated for temperature adjustment (the heat recovery equipment 26 is used to reduce energy loss associated with temperature adjustment during this process).

[0062] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
