[0002] The cabinet room of Mingqian Station adopts a color steel structure, and its heat insulation performance is poor. In summer, the indoor temperature often exceeds 40 °C, seriously threatening the stable operation of equipment.

[0003] Since there is no mains power access in Mingqian Station and it relies on photovoltaic power generation and UPS battery power supply, the traditional air conditioning cooling scheme cannot be adopted, and the existing heat dissipation means mostly use fixed-mode exhaust fans.

[0004] However, the fixed-mode exhaust fan lacks comprehensive regulation of temperature dynamic changes and the power supply system (such as battery temperature), resulting in low energy utilization efficiency and insufficient heat dissipation. In addition, Mingqian Station is in an unattended state, and personnel cannot rush to the scene immediately after an emergency occurs. This requires the heat dissipation means to have high automation and reliability. The existing methods have obvious deficiencies in the collaborative optimization of intelligent regulation and active heat dissipation, and it is difficult to meet the precise temperature control requirements in complex environments.

[0066] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0067] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0068] Please refer to Figure 1 , which is a control method for an exhaust fan used for temperature regulation in the cabinet room of Mingqian Station provided by an embodiment of the present invention, and includes the following steps:

[0069] Step S10: Obtain the temperature value of the cabinet room of Mingqian Station and generate a cabinet room status evaluation index;

[0070] Step S20: Judge the heat dissipation requirement of the cabinet room of Mingqian Station according to the cabinet room status evaluation index;

[0071] Step S30: If the heat dissipation requirement in the cabinet room is high, obtain the environmental data of Mingqian Station and the temperature value of the power supply battery of the exhaust fan, establish an analysis model for the demand for adjusting the exhaust fan mode, and generate an index for the demand for adjusting the heat dissipation mode in the cabinet room; wherein, the environmental data of Mingqian Station includes the environmental temperature value, wind speed value, and wind direction angle;

[0072] Step S40: Adjust the operating mode of the exhaust fan according to the index for the demand for adjusting the heat dissipation mode in the cabinet room.

[0073] Please refer to Figure 2 , as a preferred embodiment of the present invention, the specific steps of step S10 are as follows:

[0074] S11: Set several monitoring periods, and obtain the temperature value in the cabinet room within each monitoring period;

[0075] S12: Generate an average temperature evaluation index for the cabinet room, a temperature change evaluation index for the cabinet room, and an abnormal temperature duration evaluation index for the cabinet room respectively according to the temperature value in the cabinet room within each monitoring period;

[0076] S13: Perform weighted processing on the average temperature evaluation index for the cabinet room, the temperature change evaluation index for the cabinet room, and the abnormal temperature duration evaluation index for the cabinet room to generate a cabinet room status evaluation index.

[0077] As a preferred embodiment of the present invention, the specific method for generating the average temperature evaluation index for the cabinet room is as follows:

[0078] Perform mean processing on the temperature values in the cabinet room within all monitoring periods to generate an average temperature value;

[0079] Perform difference processing on the average temperature value and the temperature warning value to generate a temperature difference;

[0080] Perform ratio processing on the temperature difference and the temperature warning value to generate an average temperature evaluation index for the cabinet room;

[0081] It should be explained that the temperature warning value refers to the maximum temperature value under the standard state of the cabinet room; this standard state means that the equipment in the cabinet room can operate normally;

[0082] In addition, the duration of the monitoring period is set by relevant personnel in the field, and its values include but are not limited to ten minutes, half an hour, one hour, etc.;

[0083] Among them, the specific method for generating the temperature change evaluation index for the cabinet room includes:

[0084] Arrange the temperature values in the cabinet room within all monitoring periods according to time sequence to generate time series temperature data;

[0085] Perform difference processing on adjacent temperature values in the time-series temperature data to generate temperature change values;

[0086] Time series refers to the order in the direction of time flow; in this embodiment, arranging the temperature values according to the time series means arranging the monitoring periods in time order, and each monitoring period has a corresponding temperature value, that is, generating time-series temperature data; this time-series temperature data is the collection of all arranged temperature values; for example, arranging the monitoring periods in time order as 6 am, 7 am, 8 am, and the corresponding temperature values for 6 am, 7 am, 8 am are 15°C, 18°C, 24°C, that is, {15°C, 18°C, 24°C} is the collection of all arranged temperature values, that is, the time-series temperature data;

[0087] In addition, the temperature value in the cabinet room during the monitoring period is the average temperature value of the cabinet room, and this average temperature value refers to the average of the temperature values in all spaces of the cabinet room (such as the left space and the right space of the cabinet, etc.);

[0088] Perform variance processing on all the temperature change values to generate temperature change fluctuation values;

[0089] Perform difference processing on the temperature change fluctuation value and the fluctuation threshold to generate a fluctuation difference;

[0090] Perform ratio processing on the fluctuation difference and the fluctuation threshold to generate an evaluation index for the temperature change in the cabinet room;

[0091] It should be explained that the value of the fluctuation threshold is set by relevant personnel in this field;

[0092] In addition, too large a temperature fluctuation in the cabinet room will cause the equipment to switch repeatedly between high temperature and normal temperature, and the long-term temperature difference change will cause the equipment to have thermal cycle fatigue, which will accelerate the loss of internal solder joints and connections of the equipment and increase the risk of hardware failure of the equipment;

[0093] Among them, the specific generation method of the evaluation index for the continuous abnormal temperature in the cabinet room is as follows:

[0094] Compare the temperature value in the cabinet room during the monitoring period with the temperature warning value;

[0095] If the temperature value in the cabinet room during the monitoring period is greater than or equal to the temperature warning value, then this monitoring period is marked as a temperature abnormal period;

[0096] Obtain the number of temperature abnormal periods, and perform ratio processing on the number of temperature abnormal periods and the total number of monitoring periods to generate an evaluation index for the continuous abnormal temperature in the cabinet room.

[0097] As a preferred embodiment of the present invention, the specific method for judging the heat dissipation requirement of the cabinet room of Mingqian Station is as follows:

[0098] Compare the cabinet room status evaluation index with the cabinet room status evaluation index threshold value;

[0099] The value of the cabinet room status evaluation index threshold is set by relevant personnel in the field themselves;

[0100] When the cabinet room status evaluation index is less than the cabinet room status evaluation index threshold value, it indicates that the heat dissipation demand of the cabinet room is small; the smaller the cabinet room status evaluation index, the smaller the heat dissipation demand of the cabinet room; when the heat dissipation demand of the cabinet room is small, there is no need to adjust the exhaust fan;

[0101] When the cabinet room status evaluation index is greater than or equal to the cabinet room status evaluation index threshold value, it indicates that the heat dissipation demand of the cabinet room is large; the larger the cabinet room status evaluation index, the larger the heat dissipation demand of the cabinet room; when the heat dissipation demand of the cabinet room is large, it is necessary to adjust the exhaust fan to improve the status of the cabinet room;

[0102] In this embodiment, when the cabinet room status evaluation index is greater than the cabinet room status evaluation index threshold value, if the cabinet room status evaluation index is too large (for example, when the cabinet room status evaluation index is x times the cabinet room status evaluation index threshold value and x is greater than 1), certain warning measures can be taken to remind the maintenance personnel to notice this abnormal situation so as to rush to Mingqian Station for maintenance and prevent further losses caused by the heat dissipation of the exhaust fan being unable to handle this abnormal situation.

[0103] Please refer to Figure 3 , as a preferred embodiment of the present invention, the step S30 specifically includes the following steps:

[0104] S31: If the heat dissipation demand of the cabinet room is large, obtain the environmental temperature value, wind speed value and wind direction angle of Mingqian Station;

[0105] S32: Generate an environmental impact evaluation index according to the environmental temperature value, wind speed value and wind direction angle of Mingqian Station;

[0106] S33: Obtain the temperature value of the power supply battery of the exhaust fan and generate a battery temperature factor;

[0107] S34: Establish an exhaust fan mode adjustment demand analysis model, substitute the environmental impact evaluation index, the cabinet room status evaluation index and the battery temperature factor into the exhaust fan mode adjustment demand analysis model, and generate a heat dissipation mode adjustment demand index;

[0108] Among them, the expression of the exhaust fan mode adjustment demand analysis model is:

[0109] ;

[0110] In the expression, K represents the heat dissipation mode adjustment requirement index, CSI represents the cabinet room status evaluation index, EVI represents the environmental impact evaluation index, represents the battery temperature factor.

[0111] As a preferred embodiment of the present invention, the generation method of the environmental impact evaluation index is specifically as follows:

[0112] Perform a difference operation on the environmental temperature value and the temperature value in the cabinet room to generate an indoor-outdoor temperature difference value;

[0113] Perform a ratio operation on the indoor-outdoor temperature difference and the temperature value in the cabinet room to generate an environmental temperature difference evaluation index;

[0114] It should be explained that the indoor-outdoor temperature difference will exacerbate the change rate of the indoor temperature. The greater the temperature difference, the faster the change rate of the indoor temperature, and thus the higher the demand for heat dissipation;

[0115] Furthermore, perform a difference operation on the wind speed value and the minimum wind speed value to generate a wind speed difference;

[0116] Perform a ratio operation on the wind speed difference and the minimum wind speed value to generate a wind speed evaluation index;

[0117] It should be explained that the minimum wind speed value refers to the wind speed that can drive the air flow in the cabinet room and can drive the air in the cabinet room to flow out;

[0118] In this embodiment, the value of the minimum wind speed is set by relevant personnel in the field according to the data of the heat dissipation window in the cabinet room (the opening size of the heat dissipation window, the obstruction of the screen window on the heat dissipation window); the opening size of the heat dissipation window and the screen window on the heat dissipation window will block the wind from entering the cabinet room, and when the wind speed is insufficient, the wind cannot blow into the cabinet room;

[0119] Furthermore, according to the wind direction angle, screen the ventilation angle of the cabinet room to obtain the minimum angle difference; the ventilation angle refers to the angle formed by the straight line between two ventilation windows in the cabinet room and the reference line;

[0120] It should be explained that the wind direction angle is also the angle formed by the straight line of the wind flow path and the reference line; in addition, the reference line can be the longitude and latitude line, the equator line, the meridian line, the straight line formed by the edge of the cabinet room (in the horizontal plane), etc.;

[0121] The specific screening method is as follows:

[0122] Perform a difference operation on the wind direction angle and each ventilation angle of the cabinet room to generate a set of angle differences;

[0123] Arrange each angle difference in the angle difference collection by absolute value, select the smallest angle difference, and mark it as the smallest angle difference;

[0124] The minimum angle difference is compared with the angle difference threshold to generate an air circulation smoothness evaluation index; the angle difference threshold refers to the error value of the wind direction angle;

[0125] It should be explained that the wind direction angle error value refers to the maximum angle deviation value of the wind direction angle that does not affect the smoothness of natural wind passing through the cabinets;

[0126] In this embodiment, when the wind in the Mingqian station passes through the cabinet room (the cabinet room is equipped with a heat dissipation window), the wind direction angle further affects the smoothness of the wind from blowing into the cabinet room to blowing out of the cabinet room (whether there is any obstruction to the movement of the wind between the cabinets);

[0127] If the wind direction angle overlaps with the straight line formed between the two windows, the wind will flow directly into and out of the cabinets, forming a direct airflow path; in this direct airflow path, the airflow direction is consistent with the position of the air outlet (window), and the airflow is smooth and direct. When the gas flows between the cabinets, it can quickly take away the heat and flow out through the windows, thereby achieving a more efficient heat dissipation effect;

[0128] On the contrary, if the direction of the airflow is not completely aligned with the air outlet path of the window, the airflow may need to bypass obstacles between cabinets or be disturbed by some resistance factors (such as walls and equipment). This will result in low airflow efficiency, which may make it difficult for hot air to be discharged quickly and effectively, resulting in poor heat dissipation effect;

[0129] In addition, the error value of the wind direction angle is also related to the size of the window in the cabinet room. The larger the window diameter, the greater the error value. In practical applications, the size of the window cannot be too large. Too large a window will cause substances (dust, rain, etc.) outside the cabinet room to enter the cabinet room and cause damage to the equipment in the cabinet room.

[0130] Furthermore, the environmental temperature difference evaluation index, wind speed evaluation index and air circulation smoothness evaluation index are weighted to generate an environmental impact evaluation index;

[0131] For example, by the formula:

[0132] ;

[0133] Generate environmental impact assessment index EVI;

[0134] In the formula, It represents the environmental temperature difference evaluation index. It represents the wind speed rating index. It represents the evaluation index of air circulation smoothness. , , are all weight coefficients, and + + = 1;

[0135] It should be noted that , , can be obtained by means such as linear regression equation and expert consultation method.

[0136] As a preferred embodiment of the present invention, the acquisition method of the battery temperature factor is specifically as follows:

[0137] Subtract the temperature value of the battery powering the exhaust fan from the maximum value of the standard operating temperature range to generate an operating temperature difference;

[0138] The standard operating temperature range refers to the standard operating temperature range of the battery powering the exhaust fan;

[0139] Divide the operating temperature difference by the maximum value of the standard operating temperature range to generate a battery temperature factor;

[0140] In this embodiment, the temperature of the battery powering the exhaust fan is not only affected by the ambient temperature, but also increases when the exhaust fan operates at high power. When the temperature of the battery powering the exhaust fan is too high, it may cause abnormalities in the battery powering the exhaust fan and even cause irreversible damage; therefore, when adjusting the operating mode of the exhaust fan, it is necessary to consider the temperature state of the battery powering the exhaust fan to prevent the battery powering the exhaust fan from being damaged and unable to supply power to the exhaust fan.

[0141] As a preferred embodiment of the present invention, the adjustment method of the operating mode of the exhaust fan is specifically as follows:

[0142] Compare the adjustment demand index of the cabinet room heat dissipation mode with the demand index range; among them, the demand index range includes a first warning value and a second warning value, and the first threshold is less than the second threshold;

[0143] It should be noted that the values of the demand index range and the first warning value and the second warning value in the demand index range are set by relevant personnel in the field themselves, and the ways of taking values include but are not limited to linear regression, expert consultation method, etc.;

[0144] When the adjustment demand index of the cabinet room heat dissipation mode is less than or equal to the first warning value, the operating mode of the exhaust fan is adjusted to the low power mode; if the adjustment demand index of the cabinet room heat dissipation mode is smaller, it means that the adjustment demand of the cabinet room heat dissipation mode is smaller;

[0145] When the adjustment demand index of the heat dissipation mode in the cabinet room is greater than the first warning value and less than the second warning value, the operation mode of the exhaust fan is adjusted to the normal power mode; if the adjustment demand index of the heat dissipation mode in the cabinet room is larger, it indicates that the adjustment demand for the heat dissipation mode in the cabinet room is greater;

[0146] When the adjustment demand index of the heat dissipation mode in the cabinet room is greater than the second warning value, the operation mode of the exhaust fan is adjusted to the high power mode; if the adjustment demand index of the heat dissipation mode in the cabinet room is larger, it indicates that the adjustment demand for the heat dissipation mode in the cabinet room is greater; when the operation mode of the exhaust fan is adjusted to the high power mode, a warning needs to be given to the maintenance personnel to remind the maintenance personnel to notice the abnormal situation in the cabinet room so that they can rush to the scene for maintenance.
