Description

Technical Field

[0001] This invention belongs to the field of detection technology, specifically relating to a method, device, electronic equipment, and product for measuring physical characteristic parameters. Background Technology

[0002] In the petroleum and chemical industries, it is often necessary to measure the physical properties of the produced chemical substances, such as concentration and viscosity. Some of these physical properties cannot be directly detected by sensors and must be determined experimentally after the chemical substances have been produced.

[0003] Using this method results in a lag in the detection of physical property parameters of chemical substances, making it impossible to achieve real-time detection of physical property parameters during the production process. Consequently, the physical property parameters of the produced chemical substances often differ significantly from actual requirements, making it difficult to guarantee the quality of the chemical substances.

[0004] Therefore, how to provide an effective solution for real-time detection of the physical properties of the produced chemical substances has become a pressing problem to be solved in the existing technology. Summary of the Invention

[0005] The purpose of this invention is to provide a method, apparatus, electronic device, and product for measuring physical characteristic parameters, in order to solve the aforementioned problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides a method for measuring physical property parameters, comprising: Obtain a sample parameter set, wherein the sample parameters in the sample parameter set include detection data of the produced sample chemical substance measured during the production process and related to the physical property parameters of the sample chemical substance; Establish a physical property parameter estimation model for estimating the physical property parameters of sample chemical substances; Based on the physical property parameter estimation model, the estimated values ​​of the physical property parameters of the sample chemical substances corresponding to each sample parameter in the sample parameter set are calculated. With the goal of minimizing the difference between the estimated and measured physical property parameters of the chemical substances corresponding to each sample parameter, the model parameters of the physical property parameter estimation model are iteratively updated through an optimization algorithm, and the latest physical property parameter estimation model is used as the final physical property parameter estimation model when the iteration stopping condition is met. The detection data obtained by the chemical substance to be tested during the production process are used as the input to the final physical property parameter estimation model to obtain the physical property parameters of the chemical substance to be tested, wherein the chemical substance to be tested and the sample chemical substance are the same type of chemical substance.

[0007] Based on the above disclosure, this invention provides a novel scheme for real-time detection of physical property parameters of chemical substances during the production process. Specifically, it involves acquiring a sample parameter set, where the sample parameters include detection data related to the physical property parameters of the produced chemical substances measured during the production process; establishing a physical property parameter estimation model to estimate the physical property parameters of the sample chemical substances; estimating the physical property parameters of the sample chemical substances based on the physical property parameter estimation model; iteratively updating the model parameters of the physical property parameter estimation model using an optimization algorithm, with the objective of minimizing the difference between the estimated physical property parameters and the measured physical property parameters of each sample chemical substance corresponding to each sample parameter; and using the detection data of the chemical substance to be tested measured during the production process as input to the final physical property parameter estimation model to obtain the physical property parameters of the chemical substance to be tested, wherein the chemical substance to be tested and the sample chemical substances are of the same type. Thus, by minimizing the difference between the estimated physical property parameters of the sample chemical substance estimated by the physical property parameter estimation model and the measured physical property parameters, the model parameters of the physical property parameter estimation model are optimized. This ensures that the error between the estimated physical property parameters of the sample chemical substance estimated by the physical property parameter estimation model and the actual measured values ​​is kept within a small range. Consequently, the physical property parameters of the chemical substance to be tested can be accurately calculated using the physical property parameter estimation model and the detection data obtained during the production process. This allows for real-time detection of the physical property parameters of the produced chemical substance during the production process, ensuring the quality of the produced chemical substance.

[0008] In one possible design, the latest physical property parameter estimation model is used as the final physical property parameter estimation model when the iteration stopping condition is met, including: When the number of iterations reaches a preset number or the mean square error between the estimated and measured physical property parameters of the chemical substances corresponding to each sample parameter is lower than a preset threshold, the latest physical property parameter estimation model will be used as the final physical property parameter estimation model.

[0009] In one possible design, the iterative update of the model parameters of the physical property parameter estimation model using an optimization algorithm includes: The model parameters of the physical property parameter estimation model are iteratively updated using the conjugate gradient algorithm or Bayesian optimization algorithm.

[0010] In one possible design, after using the detection data of the chemical substance to be tested obtained during the production process as input to the final physical property parameter estimation model to obtain the physical property parameters of the chemical substance to be tested, the method further includes: The physical property parameters of the chemical substance to be tested are displayed through a display device.

[0011] In one possible design, the physical property parameters of the chemical substance to be tested are the concentration or viscosity of the chemical substance to be tested.

[0012] In one possible design, the detection data related to the physical property parameters of the sample chemical substance include the temperature, pressure, flow rate of the sample chemical substance, and / or the content of a specified class of substances in the reactor.

[0013] In one possible design, the sample chemical substance is petroleum or a chemical material.

[0014] Secondly, the present invention provides a physical characteristic parameter measuring device, comprising: The acquisition unit is used to acquire a sample parameter set, wherein the sample parameters in the sample parameter set include detection data of the produced sample chemical substance measured during the production process and related to the physical property parameters of the sample chemical substance. The model building unit is used to build a physical property parameter estimation model for estimating the physical property parameters of the sample chemical substances. The first calculation unit is used to estimate the physical property parameters of the sample chemical substances corresponding to each sample parameter in the sample parameter set based on the physical property parameter estimation model. The iterative update unit is used to iteratively update the model parameters of the physical property parameter estimation model by means of minimizing the difference between the estimated value and the measured value of the physical property parameter of the sample chemical substance corresponding to each sample parameter, and when the iteration stopping condition is met, the latest physical property parameter estimation model is taken as the final physical property parameter estimation model. The second calculation unit is used to take the detection data of the chemical substance to be tested during the production process as the input of the final physical property parameter estimation model to obtain the physical property parameters of the chemical substance to be tested, wherein the chemical substance to be tested and the sample chemical substance are the same type of chemical substance.

These terms are only used to distinguish one unit from another. For example, a first unit may be referred to as a second unit, and similarly, a second unit may be referred to as a first unit, without departing from the scope of the exemplary embodiments of the invention.

[0022] It should be understood that the term "and / or" that may appear in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, B exists alone, and A and B exist simultaneously.

For example, A / and B can mean: A exists alone, and A and B exist alone. In addition, the character " / " that may appear in this document generally indicates that the related objects before and after it are in an "or" relationship.

[0023] Example like Figure 1 As shown, the physical characteristic parameter measurement method provided in the first aspect of this embodiment can be executed, but is not limited to, by a computer device with certain computing resources, such as a cloud server, an edge computer configured with a GPU, a personal computer (PC, referring to a multi-purpose computer of a size, price, and performance suitable for personal use; desktop computers, laptops, mini-laptops, tablets, and ultrabooks are all personal computers), a smartphone, a personal digital assistant (PDA), or a wearable device. Figure 1 As shown, the method for measuring physical characteristic parameters may include, but is not limited to, the following steps S101 to S105.

[0024] Step S101. Obtain the sample parameter set.

[0025] The sample parameter set includes multiple sample parameters, which include detection data related to the physical property parameters of the produced chemical substances measured during the production process.

[0026] The detection data related to the physical property parameters of the sample chemical substance may include, but is not limited to, the temperature, pressure, flow rate of the sample chemical substance and / or the content of a specified type of substance in the reactor (producing the sample chemical substance) detected by sensors during the production process of the sample chemical substance. The content of the specified type of substance may be, for example, oxygen content, carbon monoxide content, etc., which may vary depending on the type of chemical substance being produced.

[0027] The physical property parameters of the sample chemical substance may include, but are not limited to, its concentration or viscosity. The sample chemical substance may be, but is not limited to, petroleum or chemical materials.

[0028] Step S102. Establish a physical property parameter estimation model for estimating the physical property parameters of the sample chemical substances.

[0029] The physical property parameter estimation model can be a mathematical formula for calculating the physical property parameters provided by a chemical substance production process provider. Alternatively, it can be a mathematical formula for calculating the physical property parameters established by extracting variables, parameters, and calculation steps.

[0030] Step S103. Based on the physical property parameter estimation model, estimate the physical property parameters of the sample chemical substances corresponding to each sample parameter in the sample parameter set.

[0031] Specifically, the sample parameters in the sample parameter set can be substituted into the physical property parameter estimation model to obtain the estimated values ​​of the physical property parameters of the sample chemical substances corresponding to each sample parameter.

[0032] Step S104. With the goal of minimizing the difference between the estimated and measured physical property parameters of the chemical substances corresponding to each sample parameter, the model parameters of the physical property parameter estimation model are iteratively updated using an optimization algorithm. When the iteration stopping condition is met, the latest physical property parameter estimation model is taken as the final physical property parameter estimation model.

[0033] When iteratively updating the model parameters of a physical property parameter estimation model using optimization algorithms, the model parameters can be updated iteratively using, but are not limited to, conjugate gradient algorithms or Bayesian optimization algorithms. During iterative updates, the latest physical property parameter estimation model can be used as the final physical property parameter estimation model when the number of iterations reaches a preset number or when the mean square error between the estimated and measured physical property parameters of the corresponding sample chemical substances is lower than a preset threshold.

[0034] In this embodiment, the difference between the estimated and measured physical property parameters of the corresponding chemical substances for each sample parameter is expressed as mean square error. The difference between the estimated and measured physical property parameters of the corresponding chemical substances for each sample parameter can be represented as follows: Where N represents the total number of sample parameters. This represents the estimated value of the physical property parameters of the chemical substance corresponding to the i-th sample parameter. This represents the measured value of the physical property parameter of the sample chemical substance corresponding to the i-th sample parameter. It is understandable that the difference between the estimated value and the measured value of the physical property parameter of the sample chemical substance corresponding to each sample parameter can also be expressed as average error or root mean square error, etc.

[0035] Step S105. Use the detection data of the chemical substance to be tested during the production process as the input to the final physical property parameter estimation model to obtain the physical property parameters of the chemical substance to be tested.

[0036] The chemical substance to be tested and the chemical substance in the sample are of the same type. The physical property parameters of the chemical substance to be tested may include, but are not limited to, its concentration or viscosity.

[0037] In one or more embodiments, after obtaining the physical property parameters of the chemical substance to be tested, the physical property parameters of the chemical substance to be tested can also be displayed through a display device so that the user can observe the physical property parameters of the chemical substance to be tested in real time.

[0038] The physical property parameter measurement method provided by this invention involves: acquiring a sample parameter set, including detection data related to the physical property parameters of a produced chemical substance during its production process; establishing a physical property parameter estimation model to estimate the physical property parameters of the chemical substance; estimating the physical property parameters of the chemical substance corresponding to each sample parameter in the sample parameter set based on the physical property parameter estimation model; iteratively updating the model parameters of the physical property parameter estimation model using an optimization algorithm, with the objective of minimizing the difference between the estimated physical property parameter values ​​and the measured physical property parameters of the chemical substance corresponding to each sample parameter; and using the detection data of the chemical substance to be tested during its production process as the input to the final physical property parameter estimation model to obtain the physical property parameters of the chemical substance to be tested, wherein the chemical substance to be tested and the sample chemical substance are of the same type of chemical substance. Thus, by minimizing the difference between the estimated and measured physical property parameters of a sample chemical substance obtained through the physical property parameter estimation model, the model parameters of the physical property parameter estimation model are optimized. This ensures that the error between the estimated and measured physical property parameters of the sample chemical substance is kept within a small range. Consequently, the physical property parameters of the chemical substance to be tested can be accurately calculated using the physical property parameter estimation model and the detection data obtained during the production process. This allows for real-time monitoring of the physical property parameters of the produced chemical substance during production, ensuring the quality of the produced chemical substance and facilitating practical application and promotion.

The first calculation unit is used to estimate the physical property parameters of the sample chemical substances corresponding to each sample parameter in the sample parameter set based on the physical property parameter estimation model. The iterative update unit is used to iteratively update the model parameters of the physical property parameter estimation model by means of minimizing the difference between the estimated value and the measured value of the physical property parameter of the sample chemical substance corresponding to each sample parameter, and when the iteration stopping condition is met, the latest physical property parameter estimation model is taken as the final physical property parameter estimation model.
