Description

Technical Field

[0001] The present invention relates to the technical field of heat measurement, and in particular to a temperature control method and system of a combustion heat measuring instrument. Background Art

[0002] In the operation of the combustion heat tester, a precision instrument, precise temperature control is undoubtedly the core element to ensure that the test results are accurate, reliable and trustworthy. This view is not only based on theoretical derivation, but also has been fully verified and emphasized in practice.

[0003] In today's highly automated industrial production lines, temperature control is one of the core links, and its importance is self-evident. However, the traditional temperature control strategies that are widely used are often limited to fixed set values ​​and are difficult to flexibly respond to a variety of combustion materials and their complex and changing combustion environments. In-depth analysis of this situation shows that each combustion material has its own unique heat release characteristics and combustion behavior patterns. For example, oil, coal and biofuels show significant differences in combustion efficiency, heat output and emissions. Traditional temperature control methods, which operate only on a single, fixed temperature threshold, are obviously unable to accurately capture and adapt to these subtle and critical changes, resulting in low energy utilization efficiency and may even cause environmental pollution and safety hazards. Furthermore, the ever-changing environmental factors have also brought unprecedented challenges to temperature control. Whether it is the temperature fluctuations caused by the change of seasons, or the slight changes in humidity, airflow speed and other factors in the production site, they may have a profound impact on the combustion process. The traditional control method lacks real-time perception and intelligent adjustment mechanism of environmental parameters, making it particularly clumsy and inefficient in the face of these uncertainties.

[0004] Therefore, it is urgent to invent a control method for a combustion heat measuring instrument to solve the problem that the combustion heat measuring instrument in the prior art is unstable and has a relatively simple control during temperature control, which in turn causes large errors in the detection results. Summary of the invention

[0005] In view of this, the present invention proposes a temperature control method and system for a combustion heat measuring instrument, aiming to solve the problem in the current technology that the combustion heat measuring instrument is unstable and the control is relatively simple during temperature control, which leads to large errors in the detection results.

[0012] Further, matching is performed between the structural information and the ignition temperature set, and determining the constant initial temperature of the outer cabinet of the combustion heat measuring instrument according to the matching result, including:

[0013] The information of each combustion object in the ignition temperature set is obtained, and matching is performed based on the information of each combustion object and the structural information of the combustion object to be detected, wherein:

[0014] If the structural information of the combustible object to be detected is consistent with any of the combustible object information, then determining that the ignition temperature corresponding to the combustible object information is the preset ignition constant temperature of the outer cabinet;

[0015] If the structural information of the combustible object to be detected is inconsistent with the information of each combustible object, the universal ignition temperature of each structure in the ignition temperature set is obtained, and the structural information of the combustible object to be detected is matched with each structure, and the universal ignition temperature of the structure consistent with the structural information of the combustible object to be detected is determined as the preset ignition constant temperature of the outer cabinet.

[0016] Furthermore, when determining the preset ignition constant temperature of the outer cabinet, it also includes:

[0017] Determining the constant initial temperature according to the relationship between the preset ignition constant temperature and the temperature limit of the constant temperature of the outer cabinet (a first preset limit temperature and a second preset limit temperature);

[0018] When the preset ignition constant temperature is lower than or equal to the first preset limit temperature, determining the constant initial temperature as the first preset limit temperature;

[0019] When the preset ignition constant temperature is higher than or equal to the second preset limit temperature, determining the constant initial temperature as the second preset limit temperature;

[0020] When the preset ignition constant temperature is higher than the first preset limit temperature, and the preset ignition constant temperature is lower than the second preset limit temperature, the constant initial temperature is determined according to the temperature difference between the preset ignition constant temperature and the second preset limit temperature;

[0021] Wherein, the first preset limit temperature is lower than the second preset limit temperature.

[0022] Further, when determining the constant initial temperature according to the temperature difference between the preset ignition constant temperature and the second preset limit temperature, it includes:

[0023] The constant initial temperature is determined according to the relationship between the temperature difference and the configured first preset temperature difference and the second preset temperature difference:

[0024] When the temperature difference is less than or equal to the first preset temperature difference, the constant initial temperature is determined to be L3;

[0025] When the temperature difference is greater than the first preset temperature difference, and the temperature difference is less than or equal to the second preset temperature difference, the constant initial temperature is determined to be L2;

[0026] When the temperature difference is greater than the second preset temperature difference, the constant initial temperature is determined to be L1;

[0027] The first preset temperature difference is smaller than the second preset temperature difference, and the first preset limit temperature is < L1 < L2 < L3 < the second preset limit temperature.

[0028] Further, when the constant initial temperature is adjusted according to the real-time temperature, it includes:

[0030] When the ambient temperature difference is greater than the second preset ambient temperature difference, the adjustment coefficient is determined to be M0;

[0031] When the ambient temperature difference is less than or equal to the second preset ambient temperature difference, and the ambient temperature difference is greater than the first preset ambient temperature difference, the adjustment coefficient is determined to be M1;

[0032] When the ambient temperature difference is less than or equal to the first preset ambient temperature difference, the adjustment coefficient is determined to be M2;

[0033] Wherein, the first preset ambient temperature difference is smaller than the second preset ambient temperature difference, and M0<M1<M2.

[0034] Compared with the prior art, the beneficial effect of the present invention is that the ignition temperature of each combustion object and the distance measurement between them are obtained, which is the basis of the entire control process. The ignition temperature is the lowest temperature that the combustion object needs to reach when a chemical reaction occurs. Therefore, understanding the ignition temperatures of different combustion objects and their relationship can help researchers accurately evaluate their combustion characteristics. Next, by constructing a distance matrix, recursive merging is performed based on the distance measurement of the ignition temperature to obtain a universal ignition temperature. This process not only provides a clear view of the relative positions between the combustion objects, but also lays the foundation for the subsequent establishment of a temperature set. The determination of the universal ignition temperature enables an effective reference point to be found between different combustion objects, thereby improving the scientificity and accuracy of temperature control. Subsequently, the ignition temperature of the combustion object of each structure is combined with the universal ignition temperature to establish an ignition temperature set. This integrated information library makes it more efficient and accurate when matching the structural information of the combustion object to be detected with the ignition temperature set. In this way, the constant initial temperature of the outer cabinet of the combustion heat measuring instrument is determined to ensure that it can maintain a stable temperature environment during testing. Finally, real-time monitoring of the temperature of the environment in which the outer cabinet is located and adjusting the constant initial temperature are important innovations of this technical solution. Changes in external ambient temperature may have a significant impact on test results. Therefore, dynamically adjusting the constant initial temperature can effectively offset the interference of external conditions on the experiment. This intelligent, dynamically adjusted temperature control method not only improves the accuracy of combustion heat determination, but also provides more flexible technical support for research in related fields.

[0069] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein.

It should be noted that, in the absence of conflict, the embodiments of the present invention and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0070] like Figure 1 As shown, in some embodiments of the present application, this embodiment provides a temperature control method of a combustion heat measuring instrument, comprising:

[0071] Step S100: obtaining the ignition temperature of each combustion object of each structure, and obtaining the distance measurement of the ignition temperature between the combustion objects of the structure.

[0072] Step S200: establishing a distance matrix according to the distance metric, and recursively merging the ignition temperatures between the combustion objects of the structure according to the distance matrix to obtain a universal ignition temperature of the structure.

[0073] Step S300: establishing an ignition temperature set according to the ignition temperature of each combustion object of each structure and the universal ignition temperature of each structure.

[0074] It can be understood that the ignition temperatures of the combustion materials in each structure are obtained. The ignition temperature refers to the lowest temperature at which the combustion materials spontaneously start to burn under specific conditions. The ignition temperatures of different combustion materials may vary greatly due to factors such as chemical properties and physical forms. After obtaining these ignition temperatures, the ignition temperature differences between the combustion materials are calculated by a certain defined "distance metric". This distance metric can be different methods such as absolute value difference, Euclidean distance, Manhattan distance, etc. The specific choice depends on the distribution of the properties of the combustion materials and the temperature data. Through calculation, the similarity or difference in ignition temperature between different combustion materials can be quantified. Secondly, a distance matrix is ​​constructed based on the distance metric results between the ignition temperatures of the combustion materials. This matrix is ​​symmetrical, in which each element represents the difference in ignition temperature between two combustion materials. The smaller the value in the matrix, the closer the ignition temperatures of the two combustion materials are, and the larger the value, the more obvious the difference in their ignition temperatures. The establishment of the distance matrix provides basic data for the subsequent recursive merging process, which clearly shows the distribution relationship of the ignition temperatures of the combustion materials. Subsequently, based on the distance matrix, the combustibles with similar ignition temperatures are merged by recursive merging. This merging usually follows a clustering algorithm, such as hierarchical clustering or adaptive clustering. In each round of merging, the system selects the combustibles with the smallest ignition temperature difference to combine, and calculates a new ignition temperature for these merged combustibles. The temperature can be the weighted average, geometric mean or other specific method of the ignition temperatures of the two. Through this recursive merging, the system can eventually merge all combustibles into a few groups, or even a unified group, to obtain a universal ignition temperature. This universal temperature represents the reference temperature of the structure in combustion control or safety design, which can simplify the management of complex combustion systems. Finally, after obtaining the universal ignition temperature of each structure, the system further establishes an ignition temperature set based on the ignition temperature of the combustibles in each structure and the universal ignition temperature. This ignition temperature set includes the initial ignition temperature of all combustibles in each structure, as well as the universal ignition temperature formed by their recursive merging. This set not only provides the system with detailed ignition temperature information of all combustibles, but also provides simplified reference data for combustion management in actual operation.

[0075] Step S400, obtaining structural information of the combustion object to be detected, and matching the structural information with the ignition temperature set, and determining the constant initial temperature of the outer cabinet of the combustion heat measuring instrument according to the matching result.

[0076] Specifically, when matching the structural information with the ignition temperature set and determining the constant initial temperature of the outer cabinet of the combustion heat measuring instrument according to the matching result, it includes: obtaining the information of each combustible in the ignition temperature set, and matching each combustible information with the structural information of the combustible to be detected, wherein: if the structural information of the combustible to be detected is consistent with any of the combustible information, then the ignition temperature corresponding to the combustible information is determined to be the preset ignition constant temperature of the outer cabinet. If the structural information of the combustible to be detected is inconsistent with each of the combustible information, then the universal ignition temperature of each structure in the ignition temperature set is obtained, and the structural information of the combustible to be detected is matched with each of the structures, and the universal ignition temperature of the structure consistent with the structural information of the combustible to be detected is determined as the preset ignition constant temperature of the outer cabinet.

[0077] Specifically, when determining the preset ignition constant temperature of the outer cabinet, it also includes: determining the constant initial temperature according to the relationship between the preset ignition constant temperature and the temperature limit of the constant temperature of the outer cabinet (the first preset limit temperature and the second preset limit temperature). When the preset ignition constant temperature is lower than or equal to the first preset limit temperature, the constant initial temperature is determined to be the first preset limit temperature. When the preset ignition constant temperature is higher than or equal to the second preset limit temperature, the constant initial temperature is determined to be the second preset limit temperature. When the preset ignition constant temperature is higher than the first preset limit temperature and the preset ignition constant temperature is lower than the second preset limit temperature, the constant initial temperature is determined according to the temperature difference between the preset ignition constant temperature and the second preset limit temperature. Wherein, the first preset limit temperature is lower than the second preset limit temperature.

[0078] Specifically, when determining the constant initial temperature according to the temperature difference between the preset ignition constant temperature and the second preset limit temperature, it includes: determining the constant initial temperature according to the relationship between the temperature difference and the configured first preset temperature difference and the second preset temperature difference: when the temperature difference is less than or equal to the first preset temperature difference, the constant initial temperature is determined to be L3. When the temperature difference is greater than the first preset temperature difference, and the temperature difference is less than or equal to the second preset temperature difference, the constant initial temperature is determined to be L2. When the temperature difference is greater than the second preset temperature difference, the constant initial temperature is determined to be L1. Among them, the first preset temperature difference is less than the second preset temperature difference, and the first preset limit temperature <L1 <L2 <L3 <second preset limit temperature.

[0079] It can be seen that the preset ignition constant temperature of the outer cabinet of the combustion heat measuring instrument is determined by matching the structural information of the combustible to be detected with the combustible information in the ignition temperature set. Among them, if the structural information of the combustible to be detected is consistent with any combustible information in the ignition temperature set, the ignition temperature corresponding to the combustible is directly used as the constant temperature; if it is inconsistent, the universal ignition temperature is used for matching to ensure that a suitable constant initial temperature can be obtained in a variety of situations. In addition, by setting temperature limits (the first and second preset limit temperatures), the range of the constant initial temperature is further standardized to ensure that it is always within a safe and effective temperature range. This multi-level matching and adjustment mechanism improves the accuracy and adaptability of temperature control and enhances the performance of the combustion heat measuring instrument.

[0080] It is understandable that obtaining the structural information of the combustible to be detected is a key step, which includes the physical properties and chemical composition of the combustible. Subsequently, by matching the information of each combustible in the ignition temperature set, it is possible to quickly determine whether the combustible to be detected is consistent with a known combustible. If consistent, the ignition temperature corresponding to the combustible will be directly used as the constant initial temperature of the outer cabinet. This direct matching method significantly improves the efficiency and accuracy of temperature setting and avoids unnecessary calculations and redundant steps. Among them, if the structural information of the combustible to be detected is inconsistent with all the combustible information in the ignition temperature set, the system will turn to use the universal ignition temperature. This process establishes the concept of universal ignition temperature, so that in the absence of specific matching information, it can still provide a safe and effective temperature reference for a variety of combustibles. This intelligent matching mechanism ensures that the combustion heat measuring instrument can maintain its operational stability under different combustible conditions. In addition, after determining the preset ignition constant temperature, the system also considers the set temperature limit. These limit values ​​(the first preset limit temperature and the second preset limit temperature) provide a safety margin for the setting of the constant initial temperature. Specifically, when the preset ignition constant temperature is lower than or equal to the first preset limit temperature, the constant initial temperature will be fixed at the limit temperature to prevent the influence of too low temperature on the experiment. On the contrary, when the preset ignition constant temperature is higher than or equal to the second preset limit temperature, the constant initial temperature will be set to this higher limit value to ensure the safety and effectiveness of the test conditions. Between these two limits, the setting of the constant initial temperature is further refined by comparing the temperature difference between the preset ignition constant temperature and the second preset limit temperature. When the temperature difference is less than or equal to the configured first preset temperature difference, the system sets the constant initial temperature to L3; when the temperature difference is greater than the first preset temperature difference but less than or equal to the second preset temperature difference, the constant initial temperature will be L2; and when the temperature difference is greater than the second preset temperature difference, the constant initial temperature is set to L1. This subdivision processing mechanism not only ensures the flexibility of temperature control, but also provides a more sophisticated operation mode for the combustion heat tester to adapt to different experimental needs.

[0081] Step S500: obtaining the real-time temperature of the environment in which the outer cabinet is located, and adjusting the constant initial temperature according to the real-time temperature.

[0082] Specifically, when the constant initial temperature is adjusted according to the real-time temperature, it includes: obtaining the ambient temperature difference between the real-time temperature and the first preset limit temperature, determining the adjustment coefficient according to the relationship between the ambient temperature difference and the configured first preset ambient temperature difference and the second preset ambient temperature difference, and adjusting the constant initial temperature according to the adjustment coefficient. When the ambient temperature difference is greater than the second preset ambient temperature difference, the adjustment coefficient is determined to be M0. When the ambient temperature difference is less than or equal to the second preset ambient temperature difference, and the ambient temperature difference is greater than the first preset ambient temperature difference, the adjustment coefficient is determined to be M1. When the ambient temperature difference is less than or equal to the first preset ambient temperature difference, the adjustment coefficient is determined to be M2. Among them, the first preset ambient temperature difference is less than the second preset ambient temperature difference, and M0<M1<M2.

[0083] It can be seen that the adjustment coefficient is determined by calculating the ambient temperature difference and according to the relationship between the difference and the preset first and second ambient temperature differences. This adjustment coefficient is used to adjust the constant initial temperature to ensure that the accuracy and stability of the test can be maintained when the environment changes. When the ambient temperature difference exceeds the set range, different adjustment coefficients (such as M0, M1, M2) are applied to flexibly respond to temperature changes. Such a design not only enhances the dynamic response capability of temperature control, but also ensures the reliability of the experiment under various environmental conditions.

[0084] It is understandable that by obtaining the real-time temperature and calculating the ambient temperature difference, this difference provides the necessary information basis for subsequent adjustments. By comparing the relationship between the real-time temperature and the first preset limit temperature, the current environmental state can be quickly judged and whether temperature adjustment is required. Further, the adjustment coefficient is determined according to the relationship between the ambient temperature difference and the preset first and second ambient temperature differences. This hierarchical adjustment mechanism enables it to adopt different adjustment strategies under different ambient temperature differences. For example, when the ambient temperature difference is greater than the second preset ambient temperature difference, the adjustment coefficient is set to M0, which may indicate a more drastic adjustment requirement to cope with the impact of environmental changes; and when the ambient temperature difference is small (such as less than or equal to the first preset ambient temperature difference), a more moderate adjustment coefficient M2 is used to ensure that the change of the constant initial temperature is not too drastic. This hierarchical adjustment mechanism not only improves the response speed to environmental changes, but also enhances the overall stability. In this way, the constant initial temperature can be kept within a reasonable range under the condition of ambient temperature changes, ensuring the working efficiency and data accuracy of the combustion heat measuring instrument during the test. In addition, this intelligent temperature adjustment also provides more possibilities for future application scenarios, such as being able to quickly adapt to changes under different laboratory conditions, reduce human intervention, and improve the degree of automation of operations.

[0085] In the above embodiment, the ignition temperature of each combustible and the distance measurement between them are obtained, which is the basis of the entire control process. The ignition temperature is the lowest temperature that the combustible needs to reach when a chemical reaction occurs. Therefore, understanding the ignition temperatures of different combustibles and their relationship can help researchers accurately evaluate their combustion characteristics. Next, by constructing a distance matrix, recursive merging is performed based on the distance measurement of the ignition temperature to obtain a universal ignition temperature. This process not only provides a clear view of the relative positions between the combustibles, but also lays the foundation for the subsequent establishment of a temperature set. The determination of the universal ignition temperature enables an effective reference point to be found between different combustibles, thereby improving the scientificity and accuracy of temperature control. Subsequently, the ignition temperature of the combustibles of each structure is combined with the universal ignition temperature to establish an ignition temperature set. This integrated information library makes it more efficient and accurate when matching the structural information of the combustible to be detected with the ignition temperature set. In this way, the constant initial temperature of the outer cabinet of the combustion heat measuring instrument is determined to ensure that it can maintain a stable temperature environment during testing. Finally, real-time monitoring of the temperature of the environment in which the outer cabinet is located and adjusting the constant initial temperature are important innovations of this technical solution. Changes in external ambient temperature may have a significant impact on test results. Therefore, dynamically adjusting the constant initial temperature can effectively offset the interference of external conditions on the experiment. This intelligent, dynamically adjusted temperature control method not only improves the accuracy of combustion heat determination, but also provides more flexible technical support for research in related fields.

[0086] In another preferred embodiment based on the above embodiment, Figure 2 As shown, this embodiment provides a temperature control system of a combustion heat measuring instrument, including: a water tank, an oxygen bomb calorimeter, a reference calorimeter, a thermopile, a data acquisition module, a model generation module, a collection module and a central control module.

[0087] Specifically, the water tank is filled with a constant temperature medium. The oxygen bomb calorimeter and the reference calorimeter are respectively arranged inside the constant temperature medium. At least two groups of thermopiles are provided, and the two groups are respectively arranged on the outside of the oxygen bomb calorimeter and the reference calorimeter. The two groups of thermopiles are used for reverse connection to form a differential calorimetric method. The data acquisition module is used to obtain the ignition temperature of each combustion object of each structure, and obtain the distance measurement of the ignition temperature between each combustion object of the structure. The model generation module is electrically connected to the data acquisition module, and the model generation module is used to establish a distance matrix according to the distance measurement, and recursively merge the ignition temperatures between each combustion object of the structure according to the distance matrix to obtain the universal ignition temperature of the structure. The acquisition module is used to obtain the structural information of the combustion object to be detected, and the acquisition module is also used to obtain the real-time temperature of the environment in which the outer cabinet is located. The central control module is electrically connected to the model generation module and the acquisition module respectively, and the central control module is used to establish an ignition temperature set according to the ignition temperature of each combustion object of each structure and the universal ignition temperature of each structure. The central control module is also used to match the structural information with the ignition temperature set, and determine the constant initial temperature of the water tank according to the matching result. The central control module is also used to adjust the constant initial temperature according to the real-time temperature.

[0088] Specifically, the central control module is also used to match the structural information with the ignition temperature set, and according to the matching result, when determining the constant initial temperature of the water tank, it includes: the central control module is also used to obtain the information of each combustible in the ignition temperature set, and match the information of each combustible with the structural information of the combustible to be detected, wherein: if the structural information of the combustible to be detected is consistent with any combustible information among the combustible information, the central control module determines that the ignition temperature corresponding to the combustible information is the preset ignition constant temperature of the water tank. If the structural information of the combustible to be detected is inconsistent with the information of each combustible, the central control module obtains the universal ignition temperature of each structure in the ignition temperature set, and the central control module is also used to match the structural information of the combustible to be detected with each structure, and determine the universal ignition temperature of the structure consistent with the structural information of the combustible to be detected as the preset ignition constant temperature of the water tank.

[0089] Specifically, when the central control module determines the preset ignition constant temperature of the water tank, it also includes: the central control module is also used to determine the constant initial temperature according to the relationship between the preset ignition constant temperature and the temperature limit of the constant temperature of the water tank (the first preset limit temperature and the second preset limit temperature).
