Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0072] The technical solutions of the present application will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and some embodiments can not be described again for the same or similar concepts or processes.

[0073] Figure 1 A flow chart of a fossil storage environment monitoring control method according to an embodiment of the present application is shown exemplarily, and the method comprises:

[0074] In step S1, the fossil storage environment is divided into multiple areas, a gas detection device is arranged in each area, and harmful gas concentration and carbon dioxide concentration in the multiple areas are acquired at multiple time points in the current control period;

[0075] In step S2, whether to start the air circulation mode in the next control period is determined according to the harmful gas concentration and the carbon dioxide concentration;

[0076] In step S3, if the air circulation mode is started in the next control period, environment outside data is acquired by a sensor arranged outside the storage environment at the end time point of the current control period, wherein the environment outside data comprises environment outside temperature and environment outside humidity;

[0077] In step S4, environment inside data is acquired by sensors arranged in multiple areas in the storage environment at the end time point of the current control period, wherein the environment inside data comprises environment inside temperature and environment inside humidity;

[0078] In step S5, the next control cycle air circulation mode is determined according to the external environment data, the internal environment data, and the carbon dioxide concentration, wherein the air circulation mode comprises an internal circulation mode and an external circulation mode.

[0079] In step S6, if the next control cycle air circulation mode is the internal circulation mode, the air purification device is started.

[0080] In step S7, if the next control cycle air circulation mode is the external circulation mode, a control scheme is determined according to the external environment data, the internal environment data, the carbon dioxide concentration, and the harmful gas concentration.

[0081] The paleontological fossil storage environment monitoring control method according to the embodiment of the present application divides the paleontological fossil storage environment into multiple regions, can more accurately grasp the environment conditions of different regions, helps to find local environment problems in time, and thus more effectively protects the paleontological fossils. The harmful gas concentration and the carbon dioxide concentration can be monitored, and the air circulation mode can be started, which can improve the air quality of the storage environment. Different air circulation modes are started according to the internal and external environment conditions, and thus the storage environment conditions are monitored and controlled. Through different air circulation modes, the preservation accuracy of the paleontological fossils can be improved, and the personnel comfort and energy consumption economy can be considered.

[0082] According to one embodiment of the present application, in step S1, the interval between adjacent time points can be set to 10 minutes, 20 minutes, etc., and each control cycle can be set to one hour, two hours, etc., and the present application does not limit this. The paleontological fossil storage environment is divided into multiple independent regions, and a gas detection device is installed in each region to accurately measure the harmful gas concentration and the carbon dioxide concentration, for example, a carbon dioxide sensor and a sulfur dioxide sensor. The harmful gas concentration includes sulfur dioxide, nitrogen oxide, etc.

[0083] According to one embodiment of the present application, in step S2, whether to start the air circulation mode in the next control cycle is determined according to the harmful gas concentration and the carbon dioxide concentration.

[0084] Figure 2 An exemplary flowchart for determining whether to start the air circulation mode in the next control cycle according to the embodiment of the present application is shown.

[0085] According to one embodiment of the present application, step S2 comprises: step S21, determining a regional importance weight according to the value of the paleontological fossil; step S22, determining a risk coefficient of the plurality of regions according to the regional importance weight, the harmful gas concentration and the carbon dioxide concentration; step S23, determining to start the air circulation mode in the next control period if the risk coefficient of any one of the plurality of regions is greater than or equal to a risk coefficient threshold value; step S24, determining not to start the air circulation mode in the next control period if the risk coefficient of any one of the plurality of regions is less than the risk coefficient threshold value.

[0086] According to one embodiment of the present application, the regions are classified into grades according to the value of the paleontological fossil, for example, the regional importance weight of a precious type specimen area is 1 and the regional importance weight of a common exhibition area is 0.8. The risk coefficient of the plurality of regions is determined in combination of the regional importance weight, the harmful gas concentration and the carbon dioxide concentration. If the risk coefficient of any one of the plurality of regions is greater than or equal to a risk coefficient threshold value (for example, 0.7), it is determined to start the air circulation mode in the next control period. If the risk coefficient of any one of the plurality of regions is less than the risk coefficient threshold value, it is determined not to start the air circulation mode in the next control period.

[0087] According to one embodiment of the present application, step S22 comprises: step S221, averaging the harmful gas concentration at a plurality of time instants in the current control period in each region to obtain an average harmful gas concentration of the plurality of regions; step S222, averaging the carbon dioxide concentration at a plurality of time instants in the current control period in each region to obtain an average carbon dioxide concentration of the plurality of regions; step S223, obtaining a maximum harmful gas concentration and a maximum carbon dioxide concentration at a plurality of time instants in the current control period in each region according to the harmful gas concentration and the carbon dioxide concentration; step S224, obtaining a harmful gas concentration threshold value and a carbon dioxide concentration threshold value; step S225, determining a risk coefficient of the plurality of regions according to the regional importance weight, the average harmful gas concentration, the average carbon dioxide concentration, the maximum harmful gas concentration, the maximum carbon dioxide concentration, the harmful gas concentration threshold value and the carbon dioxide concentration threshold value.

[0088] According to one embodiment of the present application, the average harmful gas concentration can reflect the average condition of harmful gas concentration of the region in the current control period, and the average carbon dioxide concentration can measure the average condition of carbon dioxide concentration of the region in the current control period. The harmful gas concentration maximum value and the carbon dioxide concentration maximum value can represent the extreme condition of harmful gas concentration and carbon dioxide concentration of the region in the current control period. The harmful gas concentration threshold value (for example, the sulfur dioxide concentration threshold value is 0.50 mg / m³, and the nitrogen oxide concentration threshold value is 0.24 mg / m³) and the carbon dioxide concentration threshold value (for example, 1000 ppm) are obtained. In combination with the region importance weight, the average harmful gas concentration, the average carbon dioxide concentration, the harmful gas concentration maximum value, the carbon dioxide concentration maximum value, the harmful gas concentration threshold value, and the carbon dioxide concentration threshold value, the risk coefficient can be more comprehensively evaluated.

[0089] According to one embodiment of the present application, the risk coefficient of the plurality of regions is determined according to the region importance weight, the average harmful gas concentration, the average carbon dioxide concentration, the harmful gas concentration maximum value, the carbon dioxide concentration maximum value, the harmful gas concentration threshold value, and the carbon dioxide concentration threshold value, comprising: determining the risk coefficient of the i-th region according to formula (1) ,

[0090] (1),

[0091] wherein, is the i-th region importance weight, is the carbon dioxide concentration maximum value of the i-th region, is the carbon dioxide concentration threshold value, is the average carbon dioxide concentration of the i-th region, is the s-th harmful gas concentration maximum value of the i-th region, is the s-th harmful gas concentration threshold value, is the s-th average harmful gas concentration of the i-th region, k is a weight coefficient, M is the number of types of harmful gases, and i, s, and M are all positive integers, and if is a conditional function.

[0092] According to one embodiment of the present application, in formula (1), indicates that the carbon dioxide concentration maximum value of the i-th region is greater than or equal to the carbon dioxide concentration threshold value, and the average carbon dioxide concentration of the i-th region is greater than or equal to k times the carbon dioxide concentration threshold value, the conditional function value is 1, otherwise, the conditional function value is 0, wherein k is 0.8, which is used for early warning, and only when both the instantaneous maximum value and the periodic average concentration exceed the standard, the score is counted, which can reduce the false triggering caused by temporary fluctuations. For example, if the instantaneous value of carbon dioxide concentration of a region exceeds the standard but the average value does not reach the threshold value (such as temporary tourist gathering), it will not be counted in the risk, reducing excessive control.​ The condition function value is 1 when the maximum value of the s-th harmful gas concentration of the i-th region is greater than or equal to the s-th harmful gas concentration threshold value, and the s-th average harmful gas concentration of the i-th region is greater than or equal to k times the s-th harmful gas concentration threshold value, otherwise, the condition function value is 0. The condition functions corresponding to the harmful gas concentrations of the i-th region are summed up. And After averaging, multiply the i-th region importance weight, and the risk coefficient of the i-th region is obtained. The greater the risk coefficient, the worse the air quality of the region, and the higher the risk of endangering the ancient biological fossils.

[0093] In this way, the value difference of the ancient biological fossils stored in different regions can be considered by the region importance weight, which helps to improve the safety of important fossils. Through the weight coefficient, early warning and early intervention can be realized, and by combining the average value and the maximum value, the risk degree of the region can be reduced due to the fluctuation of individual data points, and the comprehensiveness, reliability and stability of the risk coefficient are improved.

[0094] According to an embodiment of the present application, in step S3, at the end of the current control period, the environment outside data, i.e. the environment outside temperature and the environment outside humidity, are collected by the temperature sensor and the humidity sensor arranged outside the storage environment.

[0095] According to an embodiment of the present application, in step S4, at the end of the current control period, the environment inside data, i.e. the environment inside temperature and the environment inside humidity, are collected by the temperature sensor and the humidity sensor arranged in multiple regions inside the storage environment.

[0096] According to an embodiment of the present application, in step S5, the environment outside temperature and the environment inside temperature, and the environment outside humidity and the environment inside humidity are compared and analyzed respectively to evaluate the difference degree of the temperature and humidity inside and outside the environment. At the same time, combined with the carbon dioxide concentration data, the air quality inside the environment is analyzed to identify the next control period air circulation mode, wherein the air circulation mode includes the internal circulation mode and the external circulation mode. The internal circulation mode is to circulate the air inside the ancient biological fossil storage environment without air exchange with the external space, which can reduce the interference of the external environment on the environment inside, maintain the relative stability of the temperature and humidity inside the environment, and reduce energy consumption. The external circulation mode can discharge the dirty air inside the environment and introduce fresh air from the outside, which can effectively improve the air quality inside the environment, but will affect the temperature and humidity inside the environment. At the same time, the temperature difference and the humidity difference between the inside and the outside are too large, which will increase the energy consumption.

[0097] Figure 3 An exemplary flowchart for determining the next control period air circulation mode according to an embodiment of the present application is shown.

[0098] According to one embodiment of the present application, step S5 comprises: step S51, determining a maximum temperature difference value according to the outside temperature and the inside temperature; step S52, determining a temperature identification result according to the maximum temperature difference value and a preset temperature difference range threshold; step S53, determining a maximum humidity difference value according to the outside humidity and the inside humidity; step S54, determining a humidity identification result according to the maximum humidity difference value and a preset humidity difference range threshold; step S55, determining a dynamic carbon dioxide concentration threshold value according to the carbon dioxide concentration, the maximum temperature difference value and the maximum humidity difference value; step S56, determining a carbon dioxide concentration identification result according to the carbon dioxide concentration and the dynamic carbon dioxide concentration threshold value; and step S57, determining a next control cycle air circulation mode according to the temperature identification result, the humidity identification result and the carbon dioxide concentration identification result.

[0099] According to one embodiment of the present application, a maximum temperature difference is determined according to the temperature inside the environment minus the temperature outside the environment, the paleontological fossils are sensitive to temperature changes, for example, too high temperature can accelerate the decomposition of organic matter, too low temperature can cause material embrittlement, therefore, the temperature inside the environment fluctuates preferably no more than ±2℃, the maximum temperature difference is compared with a preset temperature difference range threshold value (for example, [-2℃, 2℃]), if the maximum temperature difference is within the preset temperature difference range threshold value, the temperature identification result is 1, indicating that the temperature difference inside and outside the paleontological fossil storage environment is small, if external fresh air is introduced, the temperature outside the environment will not cause large fluctuations in the temperature inside the environment, that is, will not affect the paleontological fossils, if the maximum temperature difference is not within the preset temperature difference range threshold value, the temperature identification result is 0, indicating that the temperature difference inside and outside the paleontological fossil storage environment is large, if external fresh air is introduced, the temperature outside the environment will cause large fluctuations in the temperature inside the environment, that is, will affect the paleontological fossils. A maximum humidity difference is determined according to the humidity inside the environment minus the humidity outside the environment, the paleontological fossils are sensitive to humidity changes, for example, too high humidity is easy to cause mold breeding, too low humidity causes the fossil to crack, therefore, the humidity inside the environment fluctuates preferably no more than ±5%, the maximum humidity difference is compared with a preset humidity difference range threshold value (for example, [-5%, 5%]), if the maximum humidity difference is within the preset humidity difference range threshold value, the humidity identification result is 1, indicating that the humidity difference inside and outside the paleontological fossil storage environment is small, if external fresh air is introduced, the humidity outside the environment will not cause large fluctuations in the humidity inside the environment, that is, will not affect the paleontological fossils, if the maximum humidity difference is not within the preset humidity difference range threshold value, the humidity identification result is 0, indicating that the humidity difference inside and outside the paleontological fossil storage environment is large, if external fresh air is introduced, the humidity outside the environment will cause large fluctuations in the humidity inside the environment, that is, will affect the paleontological fossils. The carbon dioxide concentration is compared with a dynamic carbon dioxide concentration threshold value, if the carbon dioxide concentration is greater than the dynamic carbon dioxide concentration threshold value, the carbon dioxide concentration identification result is 1, indicating that the carbon dioxide concentration inside the paleontological fossil storage environment is large, external fresh air needs to be introduced, if the carbon dioxide concentration is less than or equal to the dynamic carbon dioxide concentration threshold value, the carbon dioxide concentration identification result is 0, indicating that the carbon dioxide concentration inside the paleontological fossil storage environment is small, external fresh air does not need to be introduced.

[0100] According to one embodiment of the present application, a dynamic carbon dioxide concentration threshold value is determined according to the carbon dioxide concentration, the maximum temperature difference and the maximum humidity difference, including: determining the dynamic carbon dioxide concentration threshold value according to formula (2) ,

[0101] (2),

[0102] wherein, is the carbon dioxide concentration threshold value, is a maximum temperature difference value, is a preset maximum temperature difference value, is a maximum humidity difference value, is a preset maximum humidity difference value, is a preset temperature difference weight, is a preset humidity difference weight.

[0103] According to an embodiment of the present application, in formula (2), is a ratio of an absolute value of the maximum temperature difference value and a preset maximum temperature difference value (for example, 20℃), and the greater the ratio, the greater the temperature difference between the inside and outside of the paleontological fossil storage environment, is a product of a preset temperature difference weight (for example, 100ppm) and , is a ratio of an absolute value of the maximum humidity difference value and a preset maximum humidity difference value (for example, 40%), and the greater the ratio, the greater the humidity difference between the inside and outside of the paleontological fossil storage environment, is a product of a preset humidity difference weight (for example, 50ppm) and , and are summed up to obtain a dynamic carbon dioxide concentration threshold value, if the temperature and humidity difference between the inside and outside of the paleontological fossil storage environment is significant, the external circulation mode can introduce severe temperature and humidity fluctuations, at this time, the carbon dioxide concentration is allowed to be slightly higher, which can reduce the switching frequency of the external circulation mode and reduce energy consumption.

[0104] In this way, the dynamic carbon dioxide concentration threshold value can be determined based on the carbon dioxide concentration threshold value and the temperature and humidity difference between the inside and outside of the storage environment, the dynamic carbon dioxide concentration threshold value can be automatically adjusted according to the temperature and humidity difference between the inside and outside of the environment, which can better adapt to the mode demand under different environmental conditions, reduce the switching frequency of the external circulation mode, and help to maintain the stability of the storage environment and reduce the operating cost.

[0105] According to an embodiment of the present application, step S57 includes: step S571, if the carbon dioxide concentration identification result is less than 1, and any one of the temperature identification result and the humidity identification result is less than 1, determining that the air circulation mode of the next control cycle is the internal circulation mode; step S572, if the temperature identification result and the humidity identification result are both greater than or equal to 1, determining that the air circulation mode of the next control cycle is the external circulation mode; and step S573, if the carbon dioxide concentration identification result is greater than or equal to 1, determining that the air circulation mode of the next control cycle is the external circulation mode.

[0106] According to one embodiment of the present application, if the carbon dioxide concentration identification result is less than 1 (i.e., the carbon dioxide concentration is at a suitable level), and at least one of the temperature identification result and the humidity identification result is less than 1 (i.e., the temperature difference or the humidity difference is out of the acceptable range), the next control cycle air circulation mode is determined to be the internal circulation mode, reducing the adverse effects of external temperature and humidity on the paleontological fossils, maintaining the relative stability of the temperature and humidity in the environment, and reducing energy consumption. If both the temperature identification result and the humidity identification result are greater than or equal to 1 (i.e., the temperature and humidity differences are within the acceptable range), the next control cycle air circulation mode is determined to be the external circulation mode regardless of the carbon dioxide concentration, which not only maintains the relative stability of the temperature and humidity in the environment, but also improves the air quality in the environment, while reducing energy consumption. If the carbon dioxide concentration identification result is greater than or equal to 1 (i.e., the carbon dioxide concentration is high), the next control cycle air circulation mode is determined to be the external circulation mode regardless of whether the temperature and humidity differences are within the acceptable range, introducing external fresh air to reduce the carbon dioxide concentration in the environment, but increasing energy consumption to maintain the relative stability of the temperature and humidity in the environment.

[0107] According to one embodiment of the present application, in step S6, if the next control cycle air circulation mode is the internal circulation mode, an air purification device, such as an activated carbon adsorber, is turned on. The air purification devices are uniformly distributed in the paleontological fossil storage environment and purify the air in the storage environment to maintain or improve the air quality, so that the paleontological fossils can be preserved in a stable and suitable environment, avoiding potential damage to the fossils due to poor air quality.

[0108] According to one embodiment of the present application, in step S7, if the next control cycle air circulation mode is the external circulation mode, a control scheme is determined based on the external environment data, the internal environment data, the carbon dioxide concentration, and the harmful gas concentration.

[0109] Figure 4 An exemplary flowchart of a control scheme according to an embodiment of the present application is shown.

[0110] According to one embodiment of the present application, step S7 comprises: step S71, determining not to start the air conditioner if the maximum temperature difference is within the preset temperature difference range threshold; step S72, determining to start the air conditioner if the maximum temperature difference is not within the preset temperature difference range threshold; step S73, determining not to start the dehumidification or humidification device if the maximum humidity difference is within the preset humidity difference range threshold; step S74, determining to start the dehumidification or humidification device if the maximum humidity difference is not within the preset humidity difference range threshold; step S75, obtaining the maximum ventilation volume and the minimum ventilation volume of the external circulation mode; and step S76, determining the ventilation volume of the external circulation mode in the next control period according to the carbon dioxide concentration, the harmful gas concentration, the maximum ventilation volume and the minimum ventilation volume.

[0111] According to one embodiment of the present application, if the maximum temperature difference is within the preset temperature difference range threshold (for example, [-2℃, 2℃]), it is determined not to start the air conditioner, indicating that the environment outside temperature has little effect on the environment inside temperature, and after introducing the external fresh air, the environment inside temperature fluctuation is within the acceptable range, thus, the air conditioner can be not started, saving energy. If the maximum temperature difference is not within the preset temperature difference range threshold, it is determined to start the air conditioner, when the maximum temperature difference is positive, the heating mode of the air conditioner is started, and when the maximum temperature difference is negative, the cooling mode of the air conditioner is started. If the maximum humidity difference is within the preset humidity difference range threshold (for example, [-5%, 5%]), it is determined not to start the dehumidification or humidification device, indicating that the environment outside humidity has little effect on the environment inside humidity, and after introducing the external fresh air, the environment inside humidity fluctuation is within the acceptable range, thus, the dehumidification or humidification device can be not started, saving energy. If the maximum humidity difference is not within the preset humidity difference range threshold, it is determined to start the dehumidification or humidification device, when the maximum humidity difference is positive, the humidification device is started, and when the maximum humidity difference is negative, the dehumidification device is started. The maximum ventilation volume (for example, 2000m³ / h) and the minimum ventilation volume (for example, 200m³ / h) of the external circulation mode, combined with the carbon dioxide concentration, the harmful gas concentration, the maximum ventilation volume and the minimum ventilation volume, determine the ventilation volume of the external circulation mode in the next control period.

[0112] According to one embodiment of the present application, determining the ventilation volume of the external circulation mode in the next control period according to the carbon dioxide concentration, the harmful gas concentration, the maximum ventilation volume and the minimum ventilation volume comprises: determining the ventilation volume of the external circulation mode in the next control period according to formulas (3) and (4) ,

[0113] (3),

[0114] (4),

[0115] wherein, is a normalized maximum gas concentration, , , are the 1st, 2nd, …, Mth harmful gas concentrations of the i-th zone at the end of the current control period, respectively, is the carbon dioxide concentration of the i-th zone at the end of the current control period, , , are the 1st, 2nd, …, Mth harmful gas concentration thresholds, respectively, is the carbon dioxide concentration threshold, is a maximum ventilation amount, is a minimum ventilation amount, is a first normalized maximum gas concentration threshold, is a second normalized maximum gas concentration threshold, M is the number of harmful gas types, N is the number of zones, and i, s, M and N are all positive integers, if is a conditional function, max is a maximum value function, and min is a minimum value function.

[0116] According to one embodiment of the present application, in formula (3), is the ratio of the maximum value of the 1st harmful gas concentration of the plurality of zones at the end of the current control period to the 1st harmful gas concentration threshold, the larger the ratio, the greater the 1st harmful gas concentration, and similarly, , is the ratio of the maximum value of the 2nd, …, Mth harmful gas concentration of the plurality of zones at the end of the current control period to the 2nd, …, Mth harmful gas concentration threshold, is the ratio of the maximum value of the carbon dioxide concentration of the plurality of zones at the end of the current control period to the carbon dioxide concentration threshold. The maximum value of the ratio of all gas concentration maximum values to concentration thresholds can be obtained as the normalized maximum gas concentration. In formula (4), represents that when the normalized maximum gas concentration is greater than or equal to the first normalized maximum gas concentration threshold (for example, 1), the value of the conditional function is otherwise, the value of the conditional function is 0. is the difference between the normalized maximum gas concentration and the first normalized maximum gas concentration threshold, and the ratio of the difference between the first normalized maximum gas concentration threshold and the second normalized maximum gas concentration threshold (for example, 2), the larger the ratio, the greater the normalized maximum gas concentration, and the more ventilation required, is the difference between the maximum ventilation amount and the minimum ventilation amount, i.e., the adjustable ventilation amount, is the product of the adjustable ventilation amount and the conditional function corresponding to the normalized maximum gas concentration, indicating the ventilation amount required by the normalized maximum gas concentration to adjust, is the sum of the minimum ventilation and the ventilation required for the normalized maximum gas concentration, indicating the ventilation corresponding to the normalized maximum gas concentration, the larger the normalized maximum gas concentration, the more the corresponding ventilation, because the external circulation mode has a maximum ventilation limit, the minimum value of the maximum ventilation and the ventilation corresponding to the normalized maximum gas concentration is selected, that is, the ventilation of the external circulation mode in the next control period, for example, is 2000 m³ / h, is 200 m³ / h, is 1, is 2, when is 1.2, the ventilation corresponding to the normalized maximum gas concentration is 560 m³ / h.

[0117] In this way, the normalized maximum gas concentration can be obtained based on the carbon dioxide concentration and the harmful gas concentration, and by setting the maximum ventilation and the minimum ventilation and dynamically adjusting in combination with the normalized maximum gas concentration, unnecessary ventilation can be reduced as much as possible under the premise of meeting the storage environment requirements, thereby reducing energy consumption.

[0118] The paleontological fossil storage environment monitoring control method according to the embodiment of the present application divides the paleontological fossil storage environment into multiple areas, can more accurately master the environment conditions of different areas, helps to timely find local environment problems, and thus more effectively protects the paleontological fossils. The air circulation mode can be started by monitoring the harmful gas concentration and the carbon dioxide concentration, and the air quality of the storage environment can be improved. Different air circulation modes are started according to the inside and outside conditions of the environment, so as to monitor and control the storage environment conditions. Through different air circulation modes, the preservation accuracy of the paleontological fossils can be improved while the personnel comfort and energy consumption economy are taken into account. When determining the risk coefficients of the multiple areas, the value differences of the paleontological fossils stored in different areas can be considered by the area importance weight, which helps to improve the safety of important fossils. Through the weight coefficient, early warning and early intervention can be realized. By combining the average value and the maximum value, the risk degree of the area can be reduced due to the fluctuation of individual data points, and the comprehensiveness, reliability and stability of the risk coefficient are improved. When determining the dynamic carbon dioxide concentration threshold, the dynamic carbon dioxide concentration threshold can be determined based on the carbon dioxide concentration threshold and the temperature and humidity difference between the inside and outside of the storage environment. The dynamic carbon dioxide concentration threshold can be automatically adjusted according to the temperature and humidity difference between the inside and outside of the environment, which can better adapt to the mode demand under different environmental conditions, reduce the switching frequency of the external circulation mode, help to maintain the stability of the storage environment, and reduce the operating cost. When determining the ventilation volume of the external circulation mode in the next control cycle, the normalized maximum gas concentration can be obtained based on the carbon dioxide concentration and the harmful gas concentration. By setting the maximum ventilation volume and the minimum ventilation volume and dynamically adjusting in combination with the normalized maximum gas concentration, unnecessary ventilation volume can be reduced as much as possible on the premise of meeting the demand of the storage environment, so as to reduce energy consumption.
