Description

Technical Field

[0001] This application relates to the field of aquaculture environment control technology, and in particular to a ventilation control method, electronic equipment and storage medium based on aquaculture farms. Background Technology

[0002] To regulate the temperature within the farm and provide a suitable living environment for the livestock, fans are typically installed. However, in northern regions where sandstorms are frequent in winter, farms will take certain windproof measures to prevent wind damage and to avoid pathogens entering the farm with large dust particles.

[0003] In related technologies, given the wind protection measures in farms, the existing environmental control ventilation system is too simple and insufficient to simultaneously meet the ventilation and temperature regulation needs in winter. Furthermore, due to the inconvenience of air circulation in farms, the biosecurity of farms is easily affected, making it difficult to meet the different needs for air quality, temperature, and ventilation. Summary of the Invention

[0004] The main objective of this application is to propose a ventilation regulation method and device, electronic device and storage medium based on aquaculture farms, so as to simultaneously meet the ventilation and temperature regulation needs in winter, improve biosecurity in aquaculture farms, and meet different needs for air quality, temperature and ventilation.

[0005] To achieve the above objectives, one aspect of this application proposes a ventilation control method for aquaculture farms, the method comprising:

[0006] The farm is divided into multiple breeding areas, each of which is equipped with a positive pressure fan and a negative pressure fan.

[0007] In response to the start command of the first air volume mode, the set positive air volume maintenance conditions corresponding to the first air volume mode and the current indoor temperature of the breeding area are obtained.

[0008] Obtain the target temperature corresponding to the breeding target in the current breeding area; determine the current ventilation mode and the required ventilation volume corresponding to the current ventilation mode based on the indoor temperature and the target temperature; and adjust the opening ratio of the positive pressure fan or the negative pressure fan according to the required ventilation volume.

[0009] When the current ventilation status of the current breeding area is negative pressure, obtain the positive pressure ventilation parameters of the positive pressure fan and the negative pressure ventilation parameters of the negative pressure fan in the current breeding area;

[0010] Based on the positive pressure ventilation parameters and the negative pressure ventilation parameters, the current positive air volume is calculated. Based on the current positive air volume and the set positive air volume maintenance conditions, the opening ratio of the positive pressure fan and / or the negative pressure fan is adjusted to meet the set positive air volume maintenance conditions.

[0011] Furthermore, determining the current ventilation mode and the required ventilation volume corresponding to the current ventilation mode based on the indoor temperature and the target temperature includes:

[0012] If the indoor temperature is lower than the target temperature, then determine whether the temperature difference between the indoor temperature and the target temperature is within the set temperature difference range.

[0013] When the temperature difference is not within the set temperature difference range, the current ventilation mode is determined to be the minimum ventilation mode. According to the minimum ventilation mode, the opening ratio of the negative pressure fan is adjusted to the set minimum ratio, and the corresponding ventilation volume of the positive pressure fan is determined to determine the required ventilation volume.

[0014] Furthermore, determining the current ventilation mode and the required ventilation volume corresponding to the current ventilation mode based on the indoor temperature and the target temperature includes:

[0015] Determine whether the temperature difference between the indoor temperature and the target temperature is within the set temperature difference range;

[0016] If so, the current ventilation mode is determined to be linear ventilation mode. Based on the temperature difference, the respiration rate of the breeding target is determined. Based on the respiration rate and the linear ventilation mode, the current ventilation requirement is determined.

[0017] Based on the ventilation requirements and the current positive pressure ventilation parameters, the air volume and air pressure relationship curve of the positive pressure fan are linearly fitted to determine the ventilation volume of the positive pressure fan, thereby determining the required ventilation volume.

[0018] Furthermore, determining the current ventilation mode and the required ventilation volume corresponding to the current ventilation mode based on the indoor temperature and the target temperature includes:

[0019] When the indoor temperature is greater than the target temperature, and the temperature difference between the indoor temperature and the target temperature is not within the set temperature difference range, the opening angle of the air outlet of the positive pressure fan is detected.

[0020] When the opening angle reaches the maximum opening angle, the current ventilation mode is determined to be the auxiliary ventilation mode. Based on the temperature difference, the respiratory volume of the breeding target is determined. Based on the respiratory volume and the auxiliary ventilation mode, the current ventilation requirement is determined.

[0021] Based on the ventilation requirements and the current negative pressure ventilation parameters, the air volume and air pressure relationship curve of the negative pressure fan are linearly fitted to determine the ventilation volume of the negative pressure fan, thereby determining the required ventilation volume.

[0022] Furthermore, determining the current ventilation mode and the required ventilation volume corresponding to the current ventilation mode based on the indoor temperature and the target temperature includes:

[0023] When the indoor temperature is greater than the target temperature, and the temperature difference between the indoor temperature and the target temperature is not within the set temperature difference range, the opening angle of the air outlet of the positive pressure fan is detected.

[0024] When the opening angle reaches the maximum opening angle and the negative pressure fan has been running for the set time, the current ventilation mode is determined to be the maximum ventilation mode. Based on the maximum ventilation mode, the maximum ventilation volume of the negative pressure fan is determined to determine the required ventilation volume.

[0025] Furthermore, the positive pressure ventilation parameters include the total positive pressure air volume and the positive pressure activation ratio, and the negative pressure ventilation parameters include the total negative pressure air volume and the negative pressure activation ratio; the step of calculating the current positive air volume based on the positive pressure ventilation parameters and the negative pressure ventilation parameters includes:

[0026] The current positive air volume is obtained by subtracting the product of the total positive pressure air volume and the positive pressure opening ratio from the product of the total positive pressure air volume and the negative pressure opening ratio.

[0027] Furthermore, when the set positive airflow maintenance condition is to maintain the airflow in the farm according to the set positive airflow, the step of adjusting the opening ratio of the positive pressure fan and / or the negative pressure fan according to the current positive airflow and the set positive airflow maintenance condition includes:

[0028] Based on the air volume difference between the current positive air volume and the set positive air volume, the positive pressure compensation ratio of the positive pressure fan and the negative pressure compensation ratio of the negative pressure fan are determined; wherein, the set positive air volume is greater than zero.

[0029] Based on the set first adjustment step size, the positive pressure compensation ratio, and the negative pressure compensation ratio, the opening ratio of the positive pressure fan and the opening ratio of the negative pressure fan are gradually adjusted.

[0030] Furthermore, when the set positive airflow maintenance condition is to maintain the airflow in the farm according to the set positive airflow, the step of adjusting the opening ratio of the positive pressure fan and / or the negative pressure fan according to the current positive airflow and the set positive airflow maintenance condition includes:

[0031] Based on the air volume difference between the current positive air volume and the set positive air volume, determine the positive pressure compensation ratio of the positive pressure fan or the negative pressure compensation ratio of the negative pressure fan; wherein, the set positive air volume is greater than zero;

[0032] According to the set second adjustment step size, the opening ratio of the positive pressure fan is gradually adjusted according to the positive pressure compensation ratio, or the opening ratio of the negative pressure fan is gradually adjusted according to the negative pressure compensation ratio.

[0033] To achieve the above objectives, another aspect of this application provides an electronic device, which includes a memory and a processor. The memory stores a computer program, and the processor executes the computer program to implement the above-described method.

[0034] To achieve the above objectives, another aspect of the embodiments of this application proposes a computer-readable storage medium storing a computer program that, when executed by a processor, implements the above-described method.

[0035] The embodiments of this application include at least the following beneficial effects: This application provides a ventilation regulation method and device, electronic equipment, and storage medium based on aquaculture farms. This solution divides the aquaculture farm into different breeding areas to raise different breeding targets, thereby achieving diversified breeding and intelligent management. Since the breeding targets in each breeding area are different, the corresponding ventilation mode and the corresponding required ventilation volume are determined based on the temperature difference between the target temperature of the breeding target and the current indoor temperature. The opening ratio of the positive pressure fan or negative pressure fan in the current area is adjusted to meet the temperature regulation requirements. Based on the temperature regulation requirements, according to the ventilation status of the current breeding area and the set positive air volume maintenance conditions, when it is determined that the current breeding area is in a negative pressure state, that is, the aquaculture farm may not meet the set positive air volume maintenance conditions, the opening ratio of the fan and / or negative pressure fan is adjusted again so that the aquaculture farm meets the set positive air volume maintenance conditions and simultaneously meets the temperature regulation and ventilation requirements. By setting the set positive air volume maintenance conditions, the aquaculture farm is kept in a slightly positive pressure state to prevent external dust and pathogens from entering the aquaculture farm, thereby protecting the living environment of the breeding targets and improving biosecurity.

[0043] Figure 1 This is an optional flowchart of a ventilation regulation method for aquaculture farms provided in the embodiments of this application. Figure 1 The methods may include, but are not limited to, S100 to S500.

[0044] S100 divides the farm into multiple feeding areas, each equipped with a positive pressure fan and a negative pressure fan.

[0045] S200, in response to the start command of the first air volume mode, obtains the set positive air volume maintenance conditions corresponding to the first air volume mode and the current indoor temperature of the breeding area.

[0046] S300 detects the target temperature corresponding to the breeding target in the current breeding area, determines the current ventilation mode and the required ventilation volume corresponding to the current ventilation mode based on the indoor temperature and the target temperature, and adjusts the opening ratio of the positive pressure fan or negative pressure fan according to the required ventilation volume.

[0047] S400: When the current ventilation status of the current breeding area is negative pressure, obtain the positive pressure ventilation parameters of the positive pressure fan and the negative pressure ventilation parameters of the negative pressure fan in the current breeding area.

[0048] S500 calculates the current positive air volume based on the positive and negative pressure ventilation parameters, and adjusts the opening ratio of the positive pressure fan and / or negative pressure fan according to the current positive air volume and the set positive air volume maintenance conditions to meet the set positive air volume maintenance conditions.

[0049] S100 to S500, as illustrated in the embodiments of this application, divide the breeding farm into different breeding areas to achieve diversified breeding and intelligent management. Since each breeding area has different breeding targets, the corresponding ventilation mode and required ventilation volume are determined based on the temperature difference between the target temperature of the breeding target and the current indoor temperature. The operating ratio of the positive pressure fan or negative pressure fan in the current area is adjusted to meet temperature regulation requirements. Based on the temperature regulation requirements, and considering the ventilation status of the current breeding area and the set positive airflow maintenance conditions, if it is determined that the current breeding area is in a negative pressure state, meaning the breeding farm may not meet the set positive airflow maintenance conditions, the operating ratio of the fan and / or negative pressure fan is adjusted again to ensure that the breeding farm meets the set positive airflow maintenance conditions, simultaneously satisfying both temperature regulation and ventilation requirements. By setting the set positive airflow maintenance conditions, the breeding farm is kept in a slightly positive pressure state to prevent external dust and pathogens from entering the breeding farm, thereby protecting the living environment of the breeding targets and improving biosecurity.

[0050] In some embodiments, S100, the farm is divided into multiple breeding areas, each capable of breeding a corresponding target species to achieve diversified breeding. Each breeding area is equipped with a positive pressure fan and a negative pressure fan, with the negative pressure fan positioned in the same direction as the positive pressure fan, and the positive and negative pressure fans positioned relative to each other about the breeding area. By setting corresponding fans for multiple breeding areas, intelligent management of ventilation in different breeding areas is achieved.

[0051] The breeding area shall be equipped with a maximum of two negative pressure fans and a minimum of one positive pressure fan.

[0052] In some embodiments, S200 responds to the activation command of the first airflow mode, determining that the current operating first airflow mode is in operation. The first airflow mode uses the positive airflow parameter of the farm as an airflow indicator to maintain a slightly positive pressure state in the farm. This slightly positive pressure state can prevent external dust, bacteria, viruses, and other harmful substances from entering the farm through gaps or vents, thereby protecting the animals' living environment. It also helps to expel polluted air from the farm and introduce fresh air, thereby improving the air quality inside the farm, reducing the probability of cross-infection between farmed animals in different areas, and promoting the healthy growth of the farmed animals.

[0053] This solution also includes a second air volume mode, which uses the total air volume parameter of the farm as an air volume indicator to monitor the ventilation status of the farm.

[0054] For example, turning on the positive pressure protection button generates a start command for the first airflow mode. This start command uses the positive airflow parameter of the farm as the airflow indicator to ensure the farm is in a slightly positive pressure state. Turning off the positive pressure protection button generates a start command for the second airflow mode. The positive airflow parameter is converted into a total airflow parameter, which is then used as the airflow indicator to assess the farm's airflow status.

[0055] By starting the command, the maintenance conditions set in the first air volume mode are obtained, that is, the set positive air volume maintenance conditions. Through subsequent fan adjustments, the positive air volume of the current farm is made to meet the set positive air volume maintenance conditions.

[0056] In addition, the indoor temperature of the current breeding area is monitored, and preliminary temperature difference adjustments are made to meet the temperature regulation requirements.

[0057] It should be noted that the first airflow mode is typically used for the six-month period, during the winter months, to maintain a slightly positive pressure in the farm. This prevents pathogens from entering the farm with large dust particles during the winter months, thus providing a healthier, more stable, and more efficient production environment for the farm. When using negative pressure tunnel ventilation in the summer, the first airflow mode should be turned off, and the second airflow mode should be activated, changing the airflow indicator from positive airflow to total airflow.

[0058] In S300 of some embodiments, the breeding targets in the current breeding area are detected, and the corresponding target temperature is determined based on the breeding targets. Since the breeding targets in each breeding area may be different, and the suitable environmental temperatures for the breeding targets to survive may differ, the opening ratio of the fans in the corresponding breeding area is adjusted by determining the corresponding target temperature, thereby meeting the needs of different breeding targets, realizing personalized environmental control, and satisfying different requirements for temperature and ventilation.

[0059] In this embodiment, the breeding target in the current breeding area can be detected by image detection and matching, and the target temperature can be determined by a preset breeding target-target temperature correspondence table. Alternatively, a search command can be generated based on the breeding target to determine the target temperature, thereby achieving network search to determine the target temperature. Or, the breeding target in the current breeding area can be determined by a pre-input breeding target. In this embodiment, the specific method of obtaining the target temperature is not restricted.

[0060] By comparing the indoor temperature and the target temperature using the S200, the temperature difference between the two is obtained. Based on this temperature difference, the required ventilation mode for the current breeding area is determined, i.e., the current ventilation mode. The required ventilation volume for the current breeding area is then determined based on the current ventilation mode.

[0061] By adjusting the opening ratio of the positive pressure fan or the negative pressure fan according to the required ventilation volume, the indoor temperature in the current breeding area can be regulated so that the indoor temperature can reach the target temperature and meet the temperature regulation requirements of the current breeding area.

[0062] In some embodiments of S400, since the temperature regulation requirement is met by S300, when it is determined by S200 to operate in the first air volume mode, the problem regulation requirement is met, and the set positive air volume maintenance condition is also met in order to maintain the micro-positive pressure state of the farm in winter.

[0063] Detect the current pressure difference in the current feeding area, compare the current pressure difference with the set pressure difference, and determine whether the current feeding area is in a negative pressure state.

[0064] If the current pressure difference is less than the set pressure difference, the current rearing area is considered to be under negative pressure. The positive pressure ventilation parameters of the positive pressure fan and the negative pressure ventilation parameters of the negative pressure fan corresponding to the current rearing area are then measured.

[0065] The positive pressure ventilation parameters include: the positive pressure activation ratio of the positive pressure fan and the total positive pressure air volume of the positive pressure fan; the negative pressure ventilation parameters include: the negative pressure activation ratio of the negative pressure fan and the total negative pressure air volume of the negative pressure fan. The pressure difference can be adjusted according to the environment of the farm and is not specifically limited in this application.

[0066] In other words, the pressure difference is used to determine whether the current breeding area meets the set positive air volume maintenance conditions. If the pressure difference of the current breeding area is less than the set pressure difference, the current breeding area is in a negative pressure state and does not meet the set positive air volume maintenance conditions, so a pressure regulation operation strategy needs to be implemented.

[0067] In S500 of some embodiments, the current positive air volume of the current breeding area is calculated using the positive pressure ventilation parameters and negative pressure ventilation parameters obtained in S400, and the calculation formula corresponding to the first ventilation mode.

[0068] According to the set positive air volume maintenance conditions, the opening ratio of the positive pressure fan and / or the negative pressure fan is adjusted again to adjust the current positive air volume, so that the farm is in a state of slight positive pressure, which meets the set positive air volume maintenance conditions, as well as the degree adjustment and ventilation needs.

[0069] In some embodiments of the present invention, S300 may include, but is not limited to, S310 to S311:

[0070] S310: When the indoor temperature is lower than the target temperature, determine whether the temperature difference between the indoor temperature and the target temperature is within the set temperature difference range.

[0071] S311, when the temperature difference is not within the set temperature difference range, the current ventilation mode is determined to be the minimum ventilation mode. According to the minimum ventilation mode, the opening ratio of the negative pressure fan is adjusted to the set minimum ratio, and the corresponding ventilation volume of the positive pressure fan is determined to determine the required ventilation volume.

[0072] In S310 of one embodiment, the indoor temperature and the target temperature are compared. When the indoor temperature is lower than the target temperature, it is determined whether the temperature difference between the two is within the set temperature difference range.

[0073] The set temperature difference range can be (-5℃, +5℃), or it can be other values ​​according to actual needs. In this embodiment, no restrictions are placed on the set temperature difference range.

[0074] In S311 of one embodiment, when the temperature difference between the two is not within the set temperature difference range and is less than the target temperature, the ventilation mode is confirmed to be the minimum ventilation mode.

[0075] In the minimum ventilation mode, the opening ratio of the negative pressure fan is adjusted to the set minimum ratio. The corresponding ventilation volume required for the positive pressure fan to operate in the minimum ventilation mode is determined. The corresponding ventilation volume is taken as the required ventilation volume, and the opening ratio of the positive pressure fan is adjusted according to the required ventilation volume.

[0076] For example, refer to Figure 2 When the current indoor temperature is 15℃ and the target temperature is 20℃, in the minimum ventilation mode, adjust the opening ratio of the negative pressure fan to 0%. In the minimum ventilation mode, determine the corresponding ventilation volume required for the positive pressure fan to operate, and adjust the opening ratio of the positive pressure fan to 30% based on the corresponding ventilation volume.

[0077] In the above scheme, since the current indoor temperature is lower than the target temperature, there is no need to significantly reduce the temperature. It is necessary to maintain the temperature at present. Therefore, the negative pressure fan should be turned off first, and the opening ratio of the positive pressure fan should be reduced to achieve energy saving and heat preservation.

[0078] In some embodiments of the present invention, S300 may include, but is not limited to, S320 to S322:

[0079] S320 determines whether the temperature difference between the indoor temperature and the target temperature is within the set temperature difference range.

[0080] S321, if so, then determine the current ventilation mode as linear ventilation mode, determine the respiration rate of the breeding target based on the temperature difference, and determine the current ventilation requirement based on the respiration rate and linear ventilation mode.

[0081] S322, based on ventilation requirements and current positive pressure ventilation parameters, performs linear fitting on the relationship curve between air volume and air pressure of the positive pressure fan to determine the ventilation volume of the positive pressure fan, thereby determining the required ventilation volume.

[0082] In S320 of one embodiment, it is determined whether the temperature difference between the current indoor temperature and the target temperature is within the set temperature difference range.

[0083] In S321 of one embodiment, when the temperature difference between the two is within the set temperature difference range, the ventilation mode is confirmed to be linear ventilation mode, and the opening ratio of the fan will automatically change linearly.

[0084] The respiration rate of the breeding targets in the current breeding area is determined by the temperature difference.

[0085] The respiratory volume can be determined by consulting a table showing the correspondence between temperature difference and average respiratory volume per animal head. Alternatively, it can be measured using a respiratory measuring instrument.

[0086] Determine the current ventilation requirements of the current feeding area by measuring respiratory volume and linear ventilation patterns.

[0087] Ventilation requirements can be categorized into the respiratory volume needed for the current aquaculture objectives and the type of fans required to operate.

[0088] In this embodiment, under linear ventilation mode, if the type of fan to be operated is determined to be a positive pressure fan, then the current positive pressure ventilation parameters are obtained.

[0089] In S322 of one embodiment, the ventilation volume of the positive pressure fan is determined by using the positive pressure opening ratio and ventilation demand in the current positive pressure ventilation parameters and by linearly fitting the relationship curve between the air volume and air pressure of the positive pressure fan. This ventilation volume is then used as the required ventilation volume.

[0090] In other words, by using the actual positive pressure opening ratio, current ventilation requirements, and the PQ curve (air volume-pressure curve), the air volume of the positive pressure fan is determined to ensure accurate positive air volume calculation and prevent the room from entering a negative pressure state, which could lead to biosafety risks.

[0091] With the above solution, if the temperature difference between the current indoor temperature and the target temperature is within the set temperature difference range, there is no need to drastically lower the temperature. If it is necessary to maintain the temperature, the negative pressure fan should still be turned off, and the opening ratio of the positive pressure fan should be changed linearly. This makes it easier to control and predict, because in actual operation, a linear relationship makes it easier to achieve precise air volume adjustment through the control system to meet the temperature regulation needs in winter.

[0092] In some embodiments of the present invention, S300 may include, but is not limited to, S330 to S332:

[0093] S330: When the indoor temperature is higher than the target temperature and the temperature difference between the indoor temperature and the target temperature is not within the set temperature difference range, the opening angle of the positive pressure fan outlet will be detected.

[0094] S331, when the opening angle reaches the maximum opening angle, determine the current ventilation mode as auxiliary ventilation mode, determine the respiration rate of the breeding target based on the temperature difference, and determine the current ventilation demand based on the respiration rate and auxiliary ventilation mode.

[0095] S332, based on ventilation requirements and current negative pressure ventilation parameters, performs linear fitting on the air volume and air pressure relationship curve of the negative pressure fan to determine the ventilation volume of the negative pressure fan, thereby determining the required ventilation volume.

[0096] In S330 of one embodiment, the indoor temperature and the target temperature are compared. When the indoor temperature is greater than the target temperature, it is determined whether the temperature difference between the two is within the set temperature difference range.

[0097] If so, then run the linear ventilation mode, that is, run the process steps from S320 to S322.

[0098] If not, the opening angle of the current positive pressure fan outlet is detected to determine the positive pressure fan's operating status.

[0099] In S331 of one embodiment, when the indoor temperature is greater than the target temperature, the temperature difference between the two is not within the set temperature difference range, and the opening angle reaches the maximum opening angle, the positive pressure fan has reached the maximum opening ratio, the air volume has been adjusted to the maximum, and the negative pressure fan needs to be started for auxiliary exhaust, confirming that the ventilation mode is the auxiliary ventilation mode.

[0100] In assisted ventilation mode, the respiration rate of the aquaculture target is determined by the temperature difference between the indoor temperature and the target temperature.

[0101] The respiratory volume can be determined by consulting a table showing the correspondence between temperature difference and average respiratory volume per animal head. Alternatively, it can be measured using a respiratory measuring instrument.

[0102] Determine the current ventilation requirements of the current feeding area by measuring respiratory volume and auxiliary ventilation modes.

[0103] Ventilation requirements can be categorized into the respiratory volume needed for the current aquaculture objectives and the type of fan required to operate.

[0104] In this embodiment, under the auxiliary ventilation mode, if it is determined that the types of fans to be operated include negative pressure fans and positive pressure fans, then the current positive pressure ventilation parameters and the current negative pressure ventilation parameters are obtained.

[0105] In S332 of one embodiment, the ventilation volume of the negative pressure fan is determined by linearly fitting the air volume and air pressure relationship curve of the negative pressure fan according to the negative pressure opening ratio and ventilation demand in the current negative pressure ventilation parameters, and this ventilation volume is taken as the required ventilation volume.

[0106] In other words, the air volume of the negative pressure fan is determined by the actual negative pressure opening ratio, the current ventilation demand, and the PQ curve (air volume-pressure curve).

[0107] With the above scheme, if the temperature difference between the current indoor temperature and the target temperature is not within the set temperature difference range, and the indoor temperature is too high, and the positive pressure fan has reached its maximum operating ratio, then the negative pressure fan will be operated for linear control to assist in exhaust ventilation and meet the temperature regulation needs in winter.

[0108] In some embodiments of the present invention, S300 may include, but is not limited to, S340 to S341:

[0109] S340: When the indoor temperature is greater than the target temperature and the temperature difference between the indoor temperature and the target temperature is not within the set temperature difference range, the opening angle of the positive pressure fan outlet will be detected.

[0110] S341, when the opening angle reaches the maximum opening angle and the negative pressure fan has been running for the set time, the current ventilation mode is determined to be the maximum ventilation mode. Based on the maximum ventilation mode, the maximum ventilation volume of the negative pressure fan is determined to determine the required ventilation volume.

[0111] In S340 of one embodiment, the indoor temperature and the target temperature are compared. When the indoor temperature is greater than the target temperature, it is determined whether the temperature difference between the two is within the set temperature difference range.

[0112] If so, then run the linear ventilation mode, that is, run the process steps from S320 to S322.

[0113] If not, the opening angle of the current positive pressure fan outlet is detected to determine the positive pressure fan's operating status.

[0114] In S340 of one embodiment, when the opening angle of the air outlet of the positive pressure fan reaches the maximum opening angle, the positive pressure fan has reached the maximum opening ratio and the air volume has been adjusted to the maximum. Then, it is detected whether the opening time of the negative pressure fan has reached the set time.

[0115] If not, the negative pressure fan will still be set to the lowest operating ratio, and the process steps from S330 to S332 will be executed to run the auxiliary ventilation mode.

[0116] When the negative pressure fan starts at the set time, the ventilation mode is confirmed to be the maximum ventilation mode.

[0117] The set time can be 2 minutes, 5 minutes, or 10 minutes. No specific limitation is made in this application. By setting the set time, it is possible to determine whether the negative pressure fan has been turned on, thereby distinguishing between auxiliary ventilation mode and maximum ventilation mode.

[0118] In the maximum ventilation mode, determine the maximum ventilation volume required for the negative pressure fan to operate in the maximum ventilation mode, and use the maximum ventilation volume as the required ventilation volume. Then, adjust the opening ratio of the positive pressure fan according to the required ventilation volume.

[0119] For example, refer to Figure 2 When the current indoor temperature is 29℃ and the target temperature is 20℃, maintain the positive pressure fan at 100% operating ratio in the maximum ventilation mode. In the maximum ventilation mode, determine the maximum ventilation volume required for the negative pressure fan to operate. Based on the maximum ventilation volume, adjust the operating ratio of the positive pressure fan to 80%.

[0120] In some embodiments of the present invention, positive pressure ventilation parameters include: total positive pressure air volume and positive pressure activation ratio; negative pressure ventilation parameters include: total negative pressure air volume and negative pressure activation ratio; S500 may include, but is not limited to, S510 to S521:

[0121] S510: Subtract the product of the total positive pressure air volume and the positive pressure opening ratio from the product of the total positive pressure air volume and the negative pressure opening ratio to obtain the current positive air volume.

[0122] S520 determines the positive pressure compensation ratio of the positive pressure fan and the negative pressure compensation ratio of the negative pressure fan based on the air volume difference between the current positive air volume and the set positive air volume; wherein, the set positive air volume is greater than zero.

[0123] S521, based on the set first adjustment step, positive pressure compensation ratio and negative pressure compensation ratio, gradually adjust the opening ratio of the positive pressure fan and the opening ratio of the negative pressure fan.

[0124] In one embodiment S510, under the first air volume mode, the current positive air volume is calculated using the positive pressure total air volume P1, the positive pressure opening ratio R1, the negative pressure total air volume P2, and the negative pressure opening ratio R2, and the positive air volume calculation formula: P1×R1-P2×R2.

[0125] In other words, the current positive air volume is calculated as follows: the product of the total positive pressure air volume P1 and the positive pressure opening ratio R1 minus the product of the total negative pressure air volume P2 and the negative pressure opening ratio R2.

[0126] In the second airflow mode, the formula for calculating the current total airflow is: P1×R1+P2×R2, which is used to calculate the current positive airflow.

[0127] In one embodiment S520, when the set positive air volume maintenance condition is to maintain the air volume in the farm according to the set positive air volume, the air volume difference between the current positive air volume and the set positive air volume is calculated.

[0128] The set positive air volume is greater than zero.

[0129] When selecting a simultaneous compensation strategy for positive and negative pressure fans, the positive pressure compensation ratio of the positive pressure fan and the negative pressure compensation ratio of the negative pressure fan are determined by the air volume difference, so that the current positive air volume can meet the set positive air volume, thereby maintaining a slightly positive pressure state in which the air volume of the farm is always greater than zero.

[0130] In one embodiment S521, since both the positive pressure fan and the negative pressure fan can be variable speed fans, the opening ratio of the positive pressure fan is gradually adjusted by the set first adjustment step size and the positive pressure compensation ratio. At the same time, the opening ratio of the negative pressure fan is gradually adjusted by the set first adjustment step size and the negative pressure compensation ratio, so that the current air volume is always greater than zero, and the current pressure difference is not less than the set pressure difference, thus maintaining a slightly positive pressure state in which the air volume in the farm is always greater than zero.

[0131] The first adjustment step size can be adjusted according to actual needs, and is not specifically limited in this embodiment.

[0132] The above-described solution addresses the issue that temperature regulation can alter the positive airflow within the farm, potentially leading to negative pressure. This would disregard the positive airflow maintenance conditions set in the first ventilation mode. Therefore, the pressure difference is used to determine if the feeding area is under negative pressure. Based on this difference, the operating ratio of the positive and negative pressure fans is adjusted to regulate airflow and pressure, thus meeting winter ventilation requirements. This approach simultaneously addresses both ventilation and temperature regulation needs during winter. By setting the positive airflow maintenance conditions, the farm maintains a slightly positive pressure state with a consistently greater than zero airflow. This prevents external dust and pathogens from entering the farm, improving biosecurity and meeting varying requirements for air quality, temperature, and ventilation.

[0133] In some embodiments of the present invention, S500 may include, but is not limited to, S530 to S531:

[0134] S530 determines the positive pressure compensation ratio of the positive pressure fan or the negative pressure compensation ratio of the negative pressure fan based on the difference between the current positive air volume and the set positive air volume.

[0135] S531, according to the set second adjustment step, the opening ratio of the positive pressure fan is gradually adjusted according to the positive pressure compensation ratio, or the opening ratio of the negative pressure fan is gradually adjusted according to the negative pressure compensation ratio.

[0136] In one embodiment S530, when the set positive air volume maintenance condition is to maintain the air volume in the farm according to the set positive air volume, the air volume difference between the current positive air volume and the set positive air volume is calculated.

[0137] The set positive air volume is greater than zero.

[0138] When choosing between positive and negative pressure fans as a supplementary strategy, the positive pressure compensation ratio of the positive pressure fan or the negative pressure compensation ratio of the negative pressure fan is determined by the air volume difference, so that the current positive air volume can meet the set positive air volume, thereby maintaining a slightly positive pressure state in the farm with the air volume always greater than zero.

[0139] In one embodiment S531, since both the positive pressure fan and the negative pressure fan can be variable speed fans, the opening ratio of the positive pressure fan is gradually adjusted by the set second adjustment step and positive pressure compensation ratio.

[0140] Alternatively, by setting the second adjustment step size and negative pressure compensation ratio, the opening ratio of the negative pressure fan can be gradually adjusted so that the current air volume is always greater than zero, and the current pressure difference is not less than the set pressure difference, thus maintaining a slightly positive pressure state in which the air volume of the farm is always greater than zero.

[0141] The second adjustment step size can be adjusted according to actual needs, and is not specifically limited in this embodiment. Different compensation strategies correspond to different types of fans, and therefore can respond to different compensation commands and use corresponding adjustment step sizes to adjust the fans.

[0142] The above-described solution addresses the issue that temperature regulation can alter the positive airflow within the farm, potentially leading to negative pressure. This would disregard the positive airflow maintenance conditions set in the first ventilation mode. Therefore, the pressure difference is used to determine if the feeding area is under negative pressure. Based on this difference, the operating ratio of the positive or negative pressure fans is adjusted to regulate airflow and pressure, thus meeting winter ventilation requirements. This approach simultaneously addresses both ventilation and temperature regulation needs during winter. By setting the positive airflow maintenance conditions, the farm maintains a slightly positive pressure state with a consistently greater than zero airflow. This prevents external dust and pathogens from entering the farm, improving biosecurity and meeting varying requirements for air quality, temperature, and ventilation.
