[0034] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0035] Figure 1 FIG. 1 shows a flow chart of an environmental control method according to some embodiments of the present disclosure. Figure 1 As shown, the method of this embodiment includes steps S102 to S104.

[0036] In step S102, the environmental parameters in the cultivation room are monitored by monitoring equipment, and monitoring values ​​are obtained.

[0037] The monitoring device includes a sensor. For example, when the environmental parameter includes temperature, a temperature sensor can be used to monitor the temperature in the cultivation room; when the environmental parameter includes humidity, a humidity sensor can be used to monitor the humidity in the cultivation room; when the environmental parameter includes carbon dioxide concentration, a carbon dioxide sensor can be used to monitor the carbon dioxide concentration in the cultivation room.

[0038] In some embodiments, the cultivation room can be divided into zones. Each zone includes a group of monitoring devices, such as temperature sensors, humidity sensors, and carbon dioxide sensors, and the environmental parameters of each zone are adjusted by the environmental adjustment device corresponding to each zone. In this way, by dividing the cultivation room into multiple zones, each zone corresponds to a group of monitoring devices and environmental adjustment devices, and the environmental parameters in the cultivation room are adjusted based on the zones, the accuracy of the adjustment of the environmental parameters of the cultivation room can be improved.

[0039] In addition, by comparing the changes in environmental parameters of the cultures in different zones, the biological density and cultivation speed of the different zones can be analyzed, so that the positions of the culture vessels can be appropriately adjusted to balance the cultivation conditions in each area of ​​the cultivation room, reduce the impact of inconsistent rates of change in the cultivation environment, and affect the survival rate and efficiency of the cultures, so as to ensure the quality of the entire batch.

[0040] In some embodiments, the temperature sensor, humidity sensor, and carbon dioxide sensor may be implemented by an integrated sensor. That is, the temperature, humidity, and carbon dioxide concentration in the cultivation room are monitored by the integrated sensor. Alternatively, any two of the temperature sensor, humidity sensor, and carbon dioxide sensor may be implemented by an integrated sensor, for example, the temperature sensor and humidity sensor may be implemented by a temperature and humidity sensor.

[0041] Integrated sensors can improve the integration of automatic control, thereby improving the simplicity and convenience of automatic control.

[0042] In step S104, the environmental adjustment equipment deployed in the cultivation room is used to control the rate at which the environmental parameters are adjusted from the monitored values ​​to the target values.

[0043] In order to achieve efficient cultivation of the cultured organisms in the cultivation room, it is necessary to intervene in the environmental parameters in the cultivation room, that is, to intervene in the temperature, humidity, and carbon dioxide concentration. Intervention of environmental parameters includes not only adjusting the environmental parameters to the target values, but also controlling the rate at which the environmental parameters are adjusted to the target values.

[0044] This can not only meet the demand of the culture for the quantity of environmental parameters, but also meet the demand of the culture for the quantity of changes in environmental parameters, so as to further control the growth environment of the culture. For example, the cultivation temperature corresponding to the culture may not be constant, and the temperature in the cultivation room needs to be configured to change according to a specified curve, so as to configure a better cultivation environment for the culture.

[0045] In some embodiments, the environmental parameter includes temperature, the monitoring device includes a temperature sensor, the environmental conditioning device includes a refrigerator and a heater, and the rate at which the environmental parameter is adjusted from the monitored value to the target value includes: based on the outdoor environmental conditions outside the cultivation room, using the refrigerator and the heater to control the rate at which the temperature monitored value is adjusted to the temperature target value.

[0046] The refrigerator and heater refer to devices that deliver cold and hot sources to each partition in the cultivation room, and are used to reduce or increase the ambient temperature in the cultivation room, and accelerate or reduce the room temperature increase and decrease rate. The present disclosure does not limit the form of the cold and hot sources of the refrigerator and heater.

[0047] When the cultivation environment requires that the temperature in the cultivation room be controlled to change according to a certain rule within a certain period of time, simply adjusting the refrigerator and heater according to the rule may not meet the demand. This is because the temperature in the cultivation room will be affected by the outdoor environmental conditions. Outdoor environmental conditions include seasons, weather, etc. For example, when the outdoor environmental conditions are low, the rate of temperature increase in the cultivation room will be reduced. Therefore, adjusting the temperature in the cultivation room based on the outdoor environmental conditions outside the cultivation room can improve the accuracy of controlling the temperature change rate in the cultivation room.

[0048] In some embodiments, based on the outdoor environmental conditions outside the cultivation room, the rate at which the temperature monitoring value is adjusted to the temperature target value by using a refrigerator and a heater includes: when the temperature value of the outdoor environment is higher than a first specified value, within the temperature adjustment time, the cooling capacity output by the refrigerator is increased and / or the heating capacity output by the heater is reduced to control the rate at which the temperature monitoring value is adjusted to the temperature target value.

[0049] The outdoor ambient temperature value is higher than the first specified value, that is, when the outdoor ambient temperature value is high, the temperature rise rate in the cultivation room will be increased and the temperature drop rate in the cultivation room will be reduced. Therefore, the cooling capacity output by the refrigerator can be increased and / or the heating capacity output by the heater can be reduced to balance the impact of the higher outdoor ambient temperature value.

[0050] When the outdoor ambient temperature is high, increasing the cooling capacity of the refrigerator output and / or reducing the heating capacity of the heater output can reduce the impact of the high outdoor ambient temperature on the cultivation room, thereby improving the accuracy of controlling the temperature increase rate and / or temperature decrease rate in the cultivation room.

[0051] In some embodiments, based on the outdoor environmental conditions outside the cultivation room, the rate at which the temperature monitoring value is adjusted to the temperature target value by using a refrigerator and a heater includes: when the temperature value of the outdoor environment is lower than a second specified value, within the temperature adjustment time, the heating amount output by the heater is increased and / or the cooling amount output by the refrigerator is reduced to control the rate at which the temperature monitoring value is adjusted to the temperature target value.

[0052] When the outdoor ambient temperature is lower than the second specified value, that is, when the outdoor ambient temperature is low, the temperature rise rate in the cultivation room will be reduced and the temperature drop rate in the cultivation room will be increased. Therefore, the heating capacity output by the heater can be increased and / or the cooling capacity output by the refrigerator can be reduced to balance the impact of the low outdoor ambient temperature.

[0053] When the outdoor ambient temperature is low, increasing the cooling capacity of the refrigerator output and / or reducing the heating capacity of the heater output can reduce the impact of the low outdoor ambient temperature on the cultivation room, thereby improving the accuracy of controlling the temperature increase rate and / or temperature decrease rate in the cultivation room.

[0054] Figure 2 A schematic diagram of a flow chart for controlling the temperature adjustment rate according to some embodiments of the present disclosure is shown.

[0055] like Figure 2 As shown, the natural environment change factor is set according to the outdoor environment conditions outside the cultivation room. , when the natural environment temperature is high, it indicates that the natural environment change factor The cooling factor of the refrigerator decreases, and the cooling capacity of the refrigerator output can be increased and / or the heating capacity of the heater output can be reduced to compensate for the natural environmental change factors. The effect of the decrease in the cooling factor; when the natural environment temperature is low, it indicates that the natural environment change factor The heating factor decreases, which can reduce the cooling capacity of the refrigerator output and / or increase the heating capacity of the heater output to compensate for the natural environmental change factors. The impact of the decrease in heating factor.

[0056] Taking the cultivation of koji as an example, during a certain period of cultivation, the temperature of the cultivation environment needs to be raised from t1 to t2 within the time Ts, and then lowered from t2 to t1 within the time Ts, and repeated in this cycle. In this case, the cultivation environment needs to be cooled and heated.

[0057] like Figure 2As shown, when the natural environment temperature is high, the cooling factor α is set to increase, and the cooling capacity in the cultivation room is increased, including increasing the cooling capacity of the refrigerator and / or reducing the heating capacity of the heater, that is, at this time, the heating rate from t1 to t2 is reduced, and the cooling rate from t2 to t1 is increased. When the natural environment temperature is low, the heating factor β is increased to increase the heating capacity in the cultivation room, including increasing the heating capacity of the heater and / or reducing the cooling capacity of the refrigerator, that is, at this time, the heating rate from t1 to t2 is increased, and the cooling rate from t2 to t1 is reduced.

[0058] Natural environment change factors As the seasons or weather change, the increase and decrease of cooling and heating capacity also change linearly. Based on the dynamic change regulation of the above control logic, the rate of change of the room environment can be kept stable. It can reduce the impact of outdoor climate, seasons and other natural conditions on the indoor cultivation environment and reduce the occurrence of uncontrollable cultivation quality problems.

[0059] The above embodiment describes that when adjusting the temperature in the cultivation room according to the outdoor environmental conditions, the heating amount output by the heater and / or the cooling amount output by the refrigerator are adjusted accordingly to balance the impact of the temperature value of the outdoor environment on the temperature of the cultivation room, thereby achieving accurate control of the temperature change rate in the cultivation room.

[0060] It is also common to maintain the temperature, humidity and carbon dioxide concentration in the cultivation room at target values, in order to provide a relatively stable cultivation environment for the cultivated products.

[0061] In some embodiments, controlling the rate at which the environmental parameter is adjusted from the monitored value to the target value also includes: determining the heating amount output by the heater and / or the cooling amount output by the refrigerator based on the temperature monitoring value, the temperature target value, and the temperature adjustment time.

[0062] Adjusting the temperature in the cultivation room to the target value can provide a stable temperature environment for the cultured plants so that the cultured plants can grow normally. It is understood that during the cultivation of the cultured plants, multiple temperature target values ​​can be set, that is, the temperature in the cultivation room can be adjusted multiple times to meet the needs of different cultivation stages of the cultured plants.

[0063] In some embodiments, the environmental parameters also include humidity, the monitoring device includes a humidity sensor, the environmental condition device includes a dehumidifier and a humidifier, and the rate at which the environmental parameters are adjusted from the monitored value to the target value includes: determining the dehumidification amount performed by the dehumidifier and / or the humidification amount output by the humidifier based on the humidity monitoring value, the humidity target value, and the humidity adjustment time.

[0064] In addition to temperature, humidity is also an important environmental parameter that affects the production of cultured plants. Adjusting the humidity in the cultivation room to the target value can provide a stable humidity environment for the cultured plants so that they can grow normally. Similar to temperature, multiple humidity target values ​​can be set during the cultivation process of the cultured plants, and the humidity in the cultivation room can be adjusted multiple times to meet the needs of different cultivation stages of the cultured plants.

[0065] Figure 3 A schematic diagram of a process for controlling the temperature and humidity in a cultivation room according to some embodiments of the present disclosure is shown.

[0066] like Figure 3 As shown, multiple temperature and humidity sensors are deployed in the cultivation room, and each temperature and humidity sensor corresponds to a humidifier and a circulation fan for controlling the humidity in the cultivation room, and also corresponds to a refrigerator and a circulation fan, and a heater and a circulation fan for controlling the temperature in the cultivation room. The circulation fan corresponding to each temperature and humidity sensor described here may be the same or different.

[0067] For any temperature and humidity sensor, for example, taking temperature and humidity sensor 1 as an example, assuming that the current cultivation environment requires an ambient humidity of H and will continue to consume ambient moisture, the appropriate allowable reduction value is hx. Then, when the humidity monitoring value h1 of humidity sensor 1 is less than H-hx, humidifier 1 is started to humidify the area, and so on, to ensure that the humidity value of each area is maintained within the range of (H-hx)~H, and to maintain the humidity value of the entire room.

[0068] When the humidifier is turned on, the circulation fan in the current area is turned on simultaneously to make the water vapor evenly distributed in every corner of the area.

[0069] Similar to humidity, assuming that the current cultivation environment requires an ambient temperature of T and the moderately allowable temperature fluctuation is ±t, then when the temperature monitoring value of humidity sensor 1 is t1≥T+t, start the cooler 1 in this area and start the circulation fan 1 simultaneously; when the temperature monitoring value of humidity sensor 1 is t1≤T+t, start the heater 1 in this area and start the circulation fan 1 simultaneously; and so on, to ensure that the temperature environment value in the entire cultivation room remains stable.

[0070] In some embodiments, the environmental parameters also include carbon dioxide concentration, the monitoring equipment includes a carbon dioxide sensor, the environmental condition equipment includes a fresh air fan and a window opener, and the rate at which the environmental parameters are adjusted from the monitored value to the target value includes: when windows in the cultivation room are allowed to be opened, the air volume output by the fresh air fan and the air volume input into the cultivation room by opening the window using the window opener are determined based on the carbon dioxide concentration monitoring value, the carbon dioxide concentration value of the outdoor environment, the carbon dioxide concentration target value, and the adjustment time of the carbon dioxide concentration.

[0071] Carbon dioxide concentration is also an important environmental parameter of the cultivation environment. As the culture grows, the carbon dioxide concentration in the cultivation room may gradually increase. At this time, the cultivation room needs to be ventilated to reduce the carbon dioxide concentration and increase the oxygen concentration.

[0072] When the cultivation room allows windows to be opened, that is, when the environment is not necessarily closed, the carbon dioxide concentration in the cultivation room can be adjusted to the target value by opening the windows with a window opener and providing fresh air to the cultivation room with a fresh air blower. The window opener is used to automatically control the windows of the cultivation room. The windows of the cultivation room are distributed according to the building structure. They can be opened oppositely or on all four sides. The number of windows is arranged according to the indoor zoning conditions. The overall function is to ventilate with the outside world and reduce or increase the room temperature, humidity and carbon dioxide concentration.

[0073] Figure 4 A schematic diagram of a process for controlling the carbon dioxide concentration in a growing room according to some embodiments of the present disclosure is shown.

[0074] Assuming that the cultivation environment needs to control the ambient carbon dioxide concentration at a certain value, it is necessary to trigger the window opener to open the window and ventilate the room, such as Figure 4 As shown, when the carbon dioxide sensor monitors the concentration C≥Cx and the current cultivation scene is not a necessary closed environment, the window is opened and the fresh air fan is started until the ambient carbon dioxide value C≤Cy, and the current cultivation scene is determined to be a non-necessary open space, the window is closed and the fresh air fan is stopped.

[0075] Considering that the window of the cultivation room is generally located on one side, that is, it is impossible to ventilate the entire cultivation room, this may cause inconsistency in the cultivation environment of the cultivated plants at different locations in the cultivation room. Therefore, by combining a fresh air fan and matching the air outlet of the fresh air fan with the position of the window, the consistency of the cultivation environment in the cultivation room can be improved, so that the cultivated plants at different locations in the cultivation room can have a similar cultivation environment, thereby improving the growth consistency of the cultivated plants.

[0076] In some embodiments, determining the air volume output by the fresh air fan and the air volume input into the cultivation room by opening the window using a window opener includes: determining the amount of carbon dioxide that needs to be adjusted in the cultivation room based on the carbon dioxide concentration monitoring value, the carbon dioxide concentration value of the outdoor environment, and the volume of the cultivation room; determining the amount of fresh air required for the cultivation room based on the amount of carbon dioxide, the target carbon dioxide concentration value, the carbon dioxide concentration value of the outdoor environment, and the adjustment time of the carbon dioxide concentration; determining the air volume output by the fresh air fan and the air volume input into the cultivation room by opening the window using a window opener based on the fresh air volume, the window opening area of ​​the cultivation room, the wind speed of the outdoor environment, the area of ​​the air outlet of the fresh air fan, and the wind speed of the fresh air fan.

[0077] For example, suppose the volume of the growing room is The target value for carbon dioxide is , the carbon dioxide monitoring value is The outdoor carbon dioxide concentration is , the adjustment time of carbon dioxide concentration is , then the amount of fresh air required for the cultivation room is It can be determined by formula (1).

[0078] (1)

[0079] The amount of fresh air required for the cultivation room Air supply volume for new fan and window air flow The sum of the window opening area (i.e. the window ventilation area) is , the area of ​​the air outlet of the new fan is , the wind speed in the outdoor environment (i.e. natural wind speed) is , the wind speed of the new fan is , then formula (2) can be used to calculate , .

[0080] (2)

[0081] in, , .

[0082] When the amount of fresh air required in the cultivation room is a certain value, the window opening is inversely proportional to the wind speed of the fresh air fan to achieve uniform ventilation in the cultivation room.

[0083] Similar to the fresh air volume, when adjusting the temperature and humidity in the cultivation room, the cooling and heating demand in the cultivation room can also be determined according to some formulas. I will not go into details here.

[0084] By determining the amount of fresh air, cooling and heating required in the cultivation room, it is possible to achieve precise control of the carbon dioxide concentration, temperature and humidity in the cultivation room. This process is not a traditional one that relies on human experience. This can reduce the impact of human operating factors on the cultivated products due to untimely regulation of the cultivation environment, improve the accuracy of automatic control, and reduce labor costs.

[0085] The temperature target value, humidity target value, and carbon dioxide concentration target value in the above-mentioned embodiment can be any value according to their respective target ranges. That is to say, the temperature, humidity, and carbon dioxide concentration in the cultivation room can have a certain error, and the error range is, for example, within 2%. By setting the error range, the difficulty of controlling the environmental parameters in the cultivation room can be reduced, and the automatic control efficiency can be improved.

[0086] The above embodiment uses sensors, hot and cold control, and space condition change actuators (i.e., environmental adjustment devices) to achieve a specific cultivation environment in the cultivation room through linkage control means, thereby improving the quality and efficiency of microbial cultivation. Such automatic control means can also liberate manpower and reduce human interference factors. In addition, it can also provide the cultivation room with stable environmental conditions throughout the year, reduce the interference of geographical environment and climate change on the cultivation environment, and ensure production efficiency throughout the year.

[0087] In addition to the environmental conditioning devices described in the above embodiments, the environmental conditioning devices may also include a circulating fan. That is, the environmental conditioning devices include at least one of a refrigerator, a heater, a dehumidifier, a humidifier, a fresh air blower, a window opener, and a circulating fan. The circulating fan helps to keep the environmental parameters of various locations in the cultivation room at similar values. The number of circulating fans can be set to be consistent with the air outlets of the humidifier and the fresh air blower. The air outlets of the circulating fan and the fresh air blower can both be set to proportional regulation, that is, the amount of cold and heat and the rotation speed can be controlled. Through these environmental conditioning devices, the temperature, humidity, and carbon dioxide concentration in the cultivation room can be adjusted, and the uniformity of the cultivation environment in the cultivation room can be improved.

[0088] In some embodiments, when at least one of the refrigerator, heater, dehumidifier, humidifier, fresh air blower, and window opener is turned on, the circulation fan is turned on. In this way, when controlling the temperature, humidity, and carbon dioxide concentration, the environmental parameters at various locations in the cultivation room can be kept as consistent as possible, so that the cultivation environment of the cultivated products at various locations in the cultivation room can be kept as consistent as possible.

[0089] In some embodiments, the cultivation room includes a first area and a second area. The first area is adjacent to the window controlled by the window opener, and the second area is adjacent to the air outlet of the fresh air fan. The first area is deployed with a temperature and humidity sensor, a heater, a carbon dioxide sensor, and a dehumidifier. The second area is deployed with a temperature and humidity sensor, a refrigerator, a carbon dioxide sensor, and a humidifier. A circulating fan is deployed at the connection between the first area and the second area.

[0090] Figure 5 FIG. 2 shows a schematic diagram of a cultivation room according to some embodiments of the present disclosure. Figure 5As shown in the figure, the cultivation room is divided into an outer area (i.e., the first area) and an inner area (i.e., the second area). The outer area and the inner area are not physically divided, but only spatially divided. Temperature and humidity sensors and carbon dioxide sensors are deployed in both the outer area and the inner area. The equipment configuration of the outer area and the inner area is different as follows: (1) The outer area is equipped with a heater and a dehumidifier. Because the outer area is closer to the doors and windows, when the windows are opened, the cold air outside quickly invades the room. The heater can balance the temperature of the outer area in time; when the external humidity is high, the outer area can stabilize the humidity of the area through the dehumidifier; (2) The inner area is equipped with a fresh air fan, a humidifier and a refrigerator. Because the inner area is far away from the doors and windows, when the windows are opened for ventilation, the inner area may not get enough oxygen and the carbon dioxide content is too high, so oxygen is delivered through the fresh air fan. If the external air is relatively dry and the humidity in the inner area is insufficient, the humidifier in the inner area is turned on to maintain the humidity value of the inner area stable; the inner area is far away from the outdoors, and the temperature rises relatively quickly during the cultivation process. Therefore, the refrigerator delivers cold air to suppress the rate of temperature rise in the inner area. In this way, the changes in environmental temperature, humidity and carbon dioxide in the cultivation room can be accurately adjusted according to the characteristics of the inner and outer areas.

[0091] In some embodiments, the cultivation room is also connected to a small weather station to provide outdoor environmental conditions, including temperature, wind speed, wind direction, air pressure, light intensity, rainfall, etc.

[0092] The present invention regulates and changes the environmental conditions in the cultivation room through sensor monitoring technology and automatic control methods, and can effectively and automatically control the changes in environmental parameters according to different cultivation processes, provide a reliable and stable cultivation environment, and thus improve output efficiency and quality.

[0093] The above-mentioned environmental adjustment method can be executed by various automatic control devices, such as environmental adjustment devices, or by a building automatic control system. That is, the monitoring device and the environmental adjustment device are connected to the building automatic control system. The environmental adjustment method disclosed in the present invention is executed by the building automatic control system, which reuses the existing automatic control system, making the environmental adjustment method disclosed in the present invention easy to implement and also enhancing the control capability of the building automatic control system.
