[0044] In order to better understand the technical solutions provided by the embodiments of this specification, the technical solutions of the embodiments of this specification are described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0045] In this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or equipment. In the absence of more restrictions, the elements limited by the statement "comprise one..." do not exclude the existence of other identical elements in the process, method, article or equipment including the elements. The term "more than two" includes two or more than two situations.

[0046] In order to solve the technical problem of inaccurate temperature control in the heating furnace during the material heating process, the present application provides the following embodiments to solve the above problem:

[0047] The present application provides a vehicle brake system control method, which is executed in a control system of a heating furnace, wherein the heating furnace includes at least one heating section, such as Figure 1 As shown, including:

[0048] Step 101, obtaining target material information of a target material to be processed, and matching corresponding target heating parameters for each heating section according to the target material information, wherein the target heating parameters at least include a target temperature.

[0049] In the steel production process, especially in continuous casting and hot rolling, in order to ensure product quality and production efficiency, precise heating control of materials (such as slabs) is required.

[0050] Since different materials have different heating requirements, the material information records the heating parameters for heating the corresponding materials.

[0051] Therefore, when determining that the material is the material to be processed, the target material information such as the material and size information of the material can be determined by the material number, etc. Since the material needs to be heated by a heating furnace, the heating process of the heating furnace can at least include a heating section and can also include a soaking section.

[0052] The target heating parameters of the target material are further obtained from the target material information to determine the temperature setting value in each heating section. The target heating parameters at least include a target temperature, which may represent at least one temperature value reached when the heating furnace heats the target material.

[0053] In a possible embodiment, during the process of acquiring the target material information, the target material information corresponding to the target material can be acquired from a database. Specifically, the material type of the target material can be queried in the database, and after determining that the database contains the material of the type, the target material information can be acquired directly from the database.

[0054] Step 102, for each heating section, controlling the heating furnace to process the target material according to the target heating parameters.

[0055] Finally, for each heating section, the heating furnace is controlled to process the target material according to the target heating parameters. The technical solution of this embodiment can determine the target material information adapted to the material according to the type of the target material, and match the target heating parameters corresponding to the heating section therein, and control the heating furnace to process the target material in sections through the target heating parameters. Through multi-section heating, the final temperature of the material can be accurately controlled to ensure the final rolling quality of the material.

[0056] In another possible embodiment, when it is determined in the database that the material of this type does not exist, the method further includes:

[0057] Query target material information of target materials to be processed in a database;

[0058] If the target material information does not exist in the database, determining the first material information of the first material in the database, and the material similarity between the first material and the target material is greater than a first threshold;

[0059] The first material information is modified until the target material information is obtained, and the target material information matches the target material.

[0060] When the material stored in the database is not completely consistent with the target material, a first material similar to the target material is selected from the database, and the material similarity between the first material and the target material is greater than a first threshold. The material similarity can be represented by the chemical composition, physical properties, mechanical properties or thermal treatment properties of the material.

[0061] Since the first material is similar to the target material to a certain extent, the first material information of the first material and the target material information of the target material have certain similarities. Therefore, adjustments can be made based on the first material information to finally obtain the target material information that matches the target material.

[0062] Therefore, in an embodiment of the present application, when the target material information corresponding to the target material to be processed cannot be directly obtained, the technical solution in this embodiment proposes to use the first material information with a higher similarity as a reference, and continuously modify the first material information until the modified first material information is adapted to the target material.

[0063] In a possible embodiment, when the first material information is continuously modified until the target material information corresponding to the target material is obtained, the target material information is saved in a database so that after the target material is processed again by a subsequent heating furnace, the target material information can be directly obtained from the database.

[0064] In the process of modifying the first material information, in a possible embodiment, a target demand parameter of the target material is determined;

[0065] Based on the target demand parameters, in the process of controlling the heating furnace to iteratively process the target material according to the first material information, the first material information is modified until the actual parameters of the heating furnace converge to the target demand parameters.

[0066] In the continuous iteration process, each iteration process may execute the following embodiment process:

[0067] During each iteration, the first heating parameters are matched for each heating section according to the first material information; for each heating section, the heating furnace is controlled to process the target material according to the first heating parameters to obtain the actual parameters of the target material; based on the parameter difference between the actual parameters and the target requirement parameters, the first material information is modified; after the iteration is completed, the actual parameters generated by controlling the heating furnace to process the target material converge to the target requirement parameters.

[0068] In the present embodiment, the first heating parameter included in the first material information is used to control the heating furnace, perform heating of the target material, and obtain the actual parameters when the material is finally discharged from the furnace. Exemplarily, the actual parameter may be the discharge temperature. However, the target material has a required discharge temperature as a target demand parameter. Based on the parameters between the target demand parameter and the actual parameter, the first material information is continuously modified, and the modification process may be an iterative modification process until the modified first material information controls the heating furnace to heat the target material, and the final actual parameters of the target material converge to the target demand parameter.

[0069] Since the process of heating the target material by the heater can be divided into at least one heating section, the embodiment of the present application takes two heating sections as an example to specifically illustrate the modification of the first material information, wherein the two heating sections include a first heating section and a second heating section, the first heating parameter includes: a first inlet temperature and a first outlet temperature of the first heating section, a first inlet temperature and a second outlet temperature of the second heating section, the actual parameter includes an actual outlet temperature, and the temperature of the second heating section is higher than the temperature of the first heating section;

[0070] Based on the parameter difference between the actual parameter and the required parameter, the first material information is modified, including:

[0071] determining a first temperature difference between a first inlet temperature and a first outlet temperature;

[0072] determining a second temperature difference between a second inlet temperature and a second outlet temperature;

[0073] determining a third temperature difference between the actual outlet temperature and the second outlet temperature;

[0074] If the third temperature difference is greater than or equal to a third threshold, determining a preset coefficient and a preset parameter;

[0075] Determine a first weight value of the first heating segment and a second weight value of the second heating segment according to a product value of a preset coefficient and a preset parameter;

[0076] The first temperature difference value and the second temperature difference value are modified using the first weight value and the second weight value.

[0077] The content of this embodiment describes the parameters for specific modification of the first material information, that is, the modification is mainly for the temperature difference between the two heating sections. After the temperature difference is modified, the outlet temperature and the inlet temperature of each heating section can be modified synchronously. In a possible embodiment, the first outlet temperature is equal to the second inlet temperature. Since the first heating section and the second heating section are connected heating sections, in the process of modifying the temperature difference, in order to maintain the robustness of the parameters corresponding to the material information, it is necessary to modify the first temperature difference and the second temperature difference synchronously. The modification of the first temperature difference and the second temperature difference is based on the corresponding weight values, respectively, wherein the composition of the weight values ​​is respectively related to the temperature difference between the two sections. In addition, the composition of the weight value is also related to the preset coefficient and the preset parameter, wherein the preset coefficient and the preset parameter can be a fixed value of the heating section or a variable value.

[0078] In a possible embodiment, the preset coefficient includes a first coefficient and a second coefficient, the first coefficient and the second coefficient are normalized functions, and the preset parameter includes a first parameter and a second parameter;

[0079] Determining a first weight value of the first heating segment and a second weight value of the second heating segment according to a product value of a preset coefficient and a preset parameter includes:

[0080] Determining a first weight value of the first heating section according to a product value of the first coefficient and the first parameter;

[0081] A second weight value of the second heating section is determined according to the product value of the second coefficient and the second parameter.

[0082] This embodiment provides a detailed description of the specific calculation process of the first weight value and the second weight value, which can clarify the specific calculation process of the weight value during the modification of the first material information.

[0083] After determining the specific calculation method of the weight value, in a possible embodiment, the specific adjustment method of the heating section may be:

[0084] T 1n =m1a1T 1d +m2a2T 2d (1)

[0085] T 2n =m2b1T 1d +m1b2T 2d (2)

[0086] Among them, T 1n represents the first outlet temperature, T 2n represents the second outlet temperature, m1 and m2 represent preset coefficients, a1, a2, b1 and b2 represent preset parameters, T 1d Represents the first temperature difference, T 2d represents the second temperature difference.

[0087] In a possible embodiment, when modifying the first outlet temperature and the second outlet temperature, the outlet temperature may also be adjusted according to the temperature difference between the actual outlet temperature represented by the actual parameter and the target outlet temperature represented by the target demand parameter.

[0088] Specifically, when the target outlet temperature is greater than the actual outlet temperature, the heating section can be adjusted in the following manner:

[0089] T 1n =0.3a1D 1d +0.7a2T 2d (3)

[0090] T 2n =0.7b1T 1d +0.3b2T 2d (4)

[0091] Among them, T 1n represents the first outlet temperature, T 2n represents the second outlet temperature, 0.3 and 0.7 represent preset coefficients, a1, a2, b1 and b2 represent preset parameters, T 1d Represents the first temperature difference, T 2d represents the second temperature difference.

[0092] When the target outlet temperature is lower than the actual outlet temperature, the heating section can be adjusted in the following ways:

[0093] T 1n =0.7a1T 1d +0.3a2n 2d (5)

[0094] T 2n =0.3b1T 1d +0.7b2T 2d (6)

[0095] Among them, T 1n represents the first outlet temperature, T 2n represents the second outlet temperature, 0.3 and 0.7 represent preset coefficients, a1, a2, b1 and b2 represent preset parameters, T 1d Represents the first temperature difference, T 2d represents the second temperature difference.

[0096] In a possible embodiment, the first heating parameter further includes heating time;

[0097] Based on the parameter difference between the actual parameter and the required parameter, the first material information is modified, including:

[0098] The heating time is modified according to the corresponding relationship between the heating time and the first temperature difference or the second temperature difference.

[0099] For example, in this embodiment, the heating time can be updated synchronously based on the continuous updating of the temperature to maintain the stability of the updated heating parameters. The corresponding relationship between the heating time and the first temperature difference or the second temperature difference can be expressed as:

[0100] t=T i +aT 2 +bT+c (7)

[0101] Among them, a, b, c are model constants, T i is the first inlet temperature or the second inlet temperature, and T is the first temperature difference or the second temperature difference.

[0102] This embodiment provides a heating furnace temperature control device, such as Figure 2 As shown, including:
