Description

Technical Field

[0001] The invention relates to the technical field of oil tank cooling control, and in particular to an oil tank spray cooling control method and system. Background Art

[0002] In industrial production, oil tanks are often used to store various liquid fuels or chemical products. In some cases, the temperature inside the oil tank may exceed the safe range, which may cause safety hazards or product quality problems. Therefore, in order to ensure that the temperature inside the oil tank is within the safe range, cooling measures are usually required. Spray cooling is a common cooling method that sprays water or other cooling media on the surface of the oil tank and uses evaporation or heat transfer to reduce the temperature inside the oil tank. In order to achieve effective spray cooling control, it is necessary to monitor and analyze the temperature changes inside the oil tank in real time, and adjust the spray cooling working conditions according to actual conditions.

[0003] However, the traditional method determines the temperature of the oil tank by collecting the temperature at a single location. This method cannot fully understand the overall temperature of the oil tank, and according to this method, it is impossible to set accurate spray cooling conditions to spray and cool the oil tank, resulting in low cooling efficiency. In addition, the traditional method only sets the spray cooling conditions according to the temperature of the oil tank, and does not take into account the influence of the surrounding environment on the spray cooling effect of the oil tank, so that the oil tank cannot be cooled accurately, resulting in poor spray cooling effect of the oil tank. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides an oil tank spray cooling control method and system, comprising:

[0005] Acquire temperature detection data at multiple temperature detection points on the oil tank, and construct a temperature change curve for each temperature detection point based on the temperature detection data;

[0006] Analyze the temperature change curve to determine the temperature change characteristic coefficient of the temperature change curve, and determine the overall temperature change coefficient of the oil tank based on the temperature change characteristic coefficient of the temperature change curve corresponding to each temperature detection point;

[0007] Determine whether the oil tank meets the preset cooling condition according to the overall temperature variation coefficient, and after determining that the oil tank meets the preset cooling condition, determine the initial spray cooling working condition of the oil tank according to the overall temperature variation coefficient;

[0059] In an embodiment of the present application, a method for controlling the spraying and cooling of an oil tank is provided, wherein the temperature change curve is analyzed to determine the temperature change characteristic coefficient of the temperature change curve, including: calculating the average value of the temperature change curve, and determining a first curve segment greater than or equal to the average value and a second curve segment less than the average value from the temperature change curve; calculating the average values ​​of the first curve segment and the second curve segment respectively, obtaining a first mean and a second mean respectively, and determining the proportions of the first curve segment and the second curve segment in the temperature change curve respectively, obtaining a first proportion and a second proportion respectively; calculating the temperature change characteristic coefficient of the temperature change curve according to the first mean and the second mean and the first proportion and the second proportion, and the calculation formula of the temperature change characteristic coefficient is:

[0061] Among them, t is the temperature change characteristic coefficient of the temperature change curve, z1 is the first proportion, p1 is the first mean, z2 is the second proportion, and p2 is the second mean.

[0062] Specifically, the overall average level of the temperature change curve is obtained to provide a benchmark for subsequent curve segment analysis and feature extraction; the temperature change curve is divided into two parts by comparing it with the average value, so that different parts can be analyzed independently in subsequent steps; the average values ​​are calculated for the two curve segments respectively to obtain the average temperature level of each part; the proportion of the first curve segment and the second curve segment in the temperature change curve are determined respectively to obtain the first proportion z1 and the second proportion z2, and by calculating the proportion of each curve segment in the overall curve, the importance of different parts in the overall temperature change can be understood; the characteristic coefficient of the temperature change curve is calculated using the first mean and the second mean as well as the first proportion and the second proportion to quantify the characteristics of the temperature change. This step can provide a more detailed understanding of the different characteristics of temperature changes, such as the average temperature and proportion of high-temperature and low-temperature segments, by performing segmented analysis and feature extraction on the temperature change curve; by calculating the temperature change characteristic coefficient, the temperature change law can be converted into a numerical value, helping engineers and researchers to more accurately understand and compare the characteristics of different temperature change curves; after obtaining the temperature change characteristic coefficient, the oil tank cooling working conditions can be adjusted and optimized based on the data, thereby improving the cooling effect and system stability; through in-depth analysis of the temperature change curve, more actionable data and guidance are provided for engineering practice and decision-making, which helps to optimize the cooling control strategy and improve the accuracy and efficiency of oil tank temperature control.

[0063] In an embodiment of the present application, a method for controlling the spraying and cooling of an oil tank is provided, wherein the overall temperature variation coefficient of the oil tank is determined based on the temperature variation characteristic coefficient of the temperature variation curve corresponding to each temperature detection point, including: obtaining the temperature variation characteristic coefficient of the temperature variation curve corresponding to each temperature detection point, and calculating the overall temperature variation coefficient of the oil tank based on the temperature variation characteristic coefficient of the temperature variation curve corresponding to each temperature detection point.

[0065] Among them, T is the overall temperature change coefficient of the oil tank, αi is the preset position weight coefficient of the i-th temperature detection point, and ti is the temperature change characteristic coefficient of the temperature change curve corresponding to the i-th temperature detection point.

[0066] Specifically, the overall temperature change coefficient T of the oil tank is calculated based on the temperature change characteristic coefficient of the temperature change curve corresponding to each temperature detection point. The calculation process takes into account the preset position weight coefficient αi of each temperature detection point, which is used to measure the importance of different detection points in the overall temperature change. Then the temperature change characteristic coefficient of each point is multiplied by its weight coefficient, and the sum is obtained to obtain the overall temperature change coefficient. This step can comprehensively consider the temperature change law of different positions inside the oil tank by obtaining the temperature change characteristic coefficient corresponding to each temperature detection point, so as to more comprehensively understand the temperature change inside the oil tank; considering the position weight coefficient of each temperature detection point, it can more accurately reflect the contribution of different positions to the overall temperature change, which is helpful for a more accurate overall temperature change assessment; by calculating the overall temperature change coefficient of the oil tank, the overall temperature change of the oil tank can be comprehensively evaluated based on the data, providing a more reliable basis for the formulation and adjustment of the temperature control strategy; by comprehensively considering the data of multiple temperature detection points, more information and basis are provided for the comprehensive evaluation of the temperature change of the oil tank, which is helpful for formulating a more scientific and effective oil tank temperature control strategy and improving the stability and reliability of the system.

[0068] Specifically, an overall temperature variation coefficient threshold is set in advance. This threshold is usually set according to actual conditions and needs, and is used to determine whether the temperature change of the oil tank meets the preset cooling conditions; once the system obtains the overall temperature variation coefficient of the oil tank, it will compare this coefficient with the preset overall temperature variation coefficient threshold; if the overall temperature variation coefficient is greater than or equal to the overall temperature variation coefficient threshold, the system determines that the oil tank meets the preset cooling conditions; if the overall temperature variation coefficient is less than the overall temperature variation coefficient threshold, the system determines that the oil tank does not meet the preset cooling conditions. This step can automatically determine whether the temperature change of the oil tank meets the preset cooling conditions by setting the threshold of the overall temperature change coefficient and comparing it with the actual coefficient, thereby reducing the complexity of manual intervention and judgment; the cooling condition of the oil tank can be judged instantly based on the comparison result of the overall temperature change coefficient, making the assessment and processing of the oil tank status more timely and accurate; through simple comparison operations, the system can quickly and accurately determine whether the oil tank meets the preset cooling conditions, thereby improving work efficiency and the accuracy of cooling control; by setting thresholds and making comparisons, automatic judgment of the cooling condition of the oil tank is realized, the intelligence of the system is improved, human errors are reduced, and work efficiency and the accuracy of cooling control are improved.

[0069] In an embodiment of the present application, a method for controlling spray cooling of an oil tank is provided, wherein after judging that the oil tank meets the preset cooling conditions, the initial spray cooling working conditions of the oil tank are determined according to the overall temperature change coefficient, including: presetting a number of coefficient difference intervals, and each coefficient difference interval corresponds to a corresponding spray cooling working condition, the spray cooling working condition includes the spraying volume per second and the spraying liquid temperature; after judging that the oil tank meets the preset cooling conditions, the difference between the overall temperature change coefficient and the preset temperature change coefficient is calculated to obtain the coefficient difference; judging the coefficient difference interval in which the coefficient difference is located, and determining the spray cooling working conditions set in the coefficient difference interval as the initial spray cooling working conditions of the oil tank.

[0070] Specifically, a plurality of coefficient difference intervals are predetermined, and corresponding spray cooling working conditions are set for each interval, including the spraying volume per second and the spraying liquid temperature; when the overall temperature change coefficient of the oil tank meets the preset cooling conditions, the difference between the actual coefficient and the preset coefficient is calculated; the coefficient difference interval in which the oil tank is located is determined according to the coefficient difference, and then the spray cooling working conditions corresponding to the interval are selected as the initial spray cooling working conditions of the oil tank. This step automatically determines the initial spray cooling working conditions of the oil tank according to the difference between the overall temperature change coefficient and the preset temperature change coefficient, realizes the automatic selection and adjustment of the cooling working conditions, and reduces the burden on operators; by selecting the spray cooling working conditions according to the difference between the actual coefficient and the preset coefficient, it can respond to the temperature change of the oil tank in real time to ensure that the cooling working conditions match the actual situation; by setting multiple coefficient difference intervals and corresponding to different spray cooling working conditions, it realizes the refined control of the cooling working conditions, which can more accurately meet the cooling needs of the oil tank; by automatically selecting the spray cooling working conditions according to the actual situation, it realizes the intelligent and refined cooling control, which helps to improve the cooling effect and the stability of the system, while reducing manual intervention and improving work efficiency.

These data are very important for evaluating the spray cooling effect and adjusting the spray working conditions; calculate the difference between the actual environmental parameters and the preset environmental parameters to obtain the temperature difference, humidity difference and light intensity difference to evaluate the deviation between the actual environment and the expected environment; evaluate the temperature difference, humidity difference and light intensity difference to obtain the corresponding evaluation value to describe the degree of deviation between the actual environmental parameters and the preset environmental parameters; perform weighted addition calculation on the temperature evaluation value, humidity difference evaluation value and light intensity evaluation value according to the preset weights to obtain the final environmental impact assessment value, which can be used to comprehensively evaluate the impact of the actual environment on the spray cooling effect. This step can comprehensively evaluate the impact of the actual environment on the spray cooling effect by calculating the difference between the actual environmental parameters and the preset environmental parameters, and evaluating and weighted calculation of these differences, so as to more accurately adjust the spray working conditions; after obtaining the environmental impact assessment value, the system can automatically adjust the spray cooling working conditions to cope with the impact of the actual environment, improve the cooling effect and ensure the stability of the system; by acquiring and analyzing the environmental parameter data, the system can make decisions based on actual conditions, improve the intelligence and refinement of cooling control, and help improve work efficiency and cooling effect; by comprehensively considering the impact of the actual environment on the cooling effect, the intelligent adjustment of the cooling working conditions is realized, and the stability of the system and the accuracy of the cooling effect are improved.

[0074] Specifically, for each variation interval of each key characteristic parameter, a corresponding correction coefficient-environmental impact assessment value interval correspondence is pre-set, and this correspondence is used to describe the degree of influence of the environmental impact assessment value on the correction coefficient in different intervals; the current environmental impact assessment value is obtained, which is usually obtained through previous environmental parameter data and evaluation methods, and is used to describe the degree of influence of the actual environment on the spray cooling effect; according to the mapping relationship of the environmental impact assessment value in the correction coefficient-environmental impact assessment value interval correspondence, the correction coefficient corresponding to the environmental impact assessment value interval is selected as the corresponding correction coefficient, and this correction coefficient will be used to adjust or correct the working parameters of the system to cope with the influence of the actual environment on the spray cooling effect. In this step, by presetting the correspondence between the correction coefficient and the environmental impact assessment value interval, the system can select the corresponding correction coefficient according to the different intervals of the actual environmental impact assessment value, thereby realizing fine adjustment of the working parameters and improving the adaptability to environmental changes; the corresponding correction coefficient can be automatically selected according to the change of the actual environmental impact assessment value, and the working parameters can be adaptively adjusted in different environments to ensure the stability and accuracy of the spray cooling effect; by analyzing the environmental parameter data and presetting the correspondence between the correction coefficient and the environmental impact assessment value interval, the system can make decisions based on the actual situation, thereby improving the intelligence and refinement of the cooling control and helping to improve the work efficiency and cooling effect; by presetting the interval correspondence and selecting the corresponding correction coefficient according to the actual environmental impact assessment value, the adaptive adjustment of the system working parameters is realized, and the adaptability of the system to environmental changes and the accuracy of the cooling control are improved.

[0076] Specifically, a corresponding correction coefficient is selected according to the interval to which the environmental impact assessment value belongs. The correction coefficient is usually determined according to the different variation ranges of the environmental impact assessment value, and is used to adjust the spray cooling working conditions to cope with the impact of the actual environment; the correction coefficient is multiplied with the spray volume per second and the spray liquid temperature in the initial spray cooling working conditions of the oil tank, respectively, to obtain the final spray volume per second and the final spray liquid temperature after correction; the final spray volume per second and the final spray liquid temperature are combined together to obtain the final spray cooling working conditions of the oil tank, which will be used to guide the actual spray cooling operation to ensure that the oil tank obtains an appropriate cooling effect while taking the correction coefficient into consideration.
