Description

Technical Field

[0001] This invention belongs to the field of rolling mill support roll technology, specifically relating to a method, system, terminal, and storage medium for handling the tilted state of rolling mill support rolls. Background Technology

[0002] The existing support roller balancing system consists of four hydraulic cylinders symmetrically positioned on both the operating and transmission sides of the rolling mill, which operate synchronously via hydraulic power. However, due to mechanical wear, internal leakage in the hydraulic cylinders, and the inclusion of iron oxide scale, asynchronous operation of the two sets of balance rollers frequently occurs, severely impacting production rhythm and safety.

[0003] Most rolling mill support rolls are designed as flat beams. However, while this design effectively prevents tilting caused by asynchrony at both ends of the support rolls, it is structurally complex, leading to a significant increase in the mechanical costs of the rolling mill. Furthermore, this method can only prevent tilting, but cannot detect the tilting state. Summary of the Invention

[0004] To address the aforementioned shortcomings of the prior art, this invention provides a method, system, terminal, and storage medium for handling the tilting state of rolling mill support rolls, thereby solving the aforementioned technical problems.

[0005] In a first aspect, the present invention provides a method for handling the tilted state of a rolling mill support roll, comprising: The first distance from the operating side hydraulic cylinder to the upper plane of the support roller bearing seat is detected using a first laser rangefinder, and the second distance from the transmission side of the hydraulic cylinder to the upper plane of the support roller bearing seat is detected using a second laser rangefinder. Calculate the difference between the first distance and the second distance. If the absolute value of the difference reaches a preset error threshold, an adjustment task is generated. The adjustment task is sent to the PID controller, so that the PID controller generates adjustment signals for the speed control valves on both sides of the support roller based on the adjustment task.

[0006] In one optional embodiment, the base of the first laser rangefinder is mounted on the lower surface of the horizontal platform of the operating side hydraulic cylinder, and the detection beam of the first laser rangefinder is perpendicular to the lower surface of the horizontal platform and points to the upper plane of the support roller bearing seat; the base of the second laser rangefinder is mounted on the lower surface of the horizontal platform of the transmission side hydraulic cylinder, and the detection beam of the second laser rangefinder is perpendicular to the lower surface of the horizontal platform and points to the upper plane of the support roller bearing seat.

[0007] In an optional implementation, both the first laser rangefinder and the second laser rangefinder are connected to the controller via a signal amplifier and an analog-to-digital converter.

[0008] In an optional implementation, the difference between a first distance and a second distance is calculated. If the absolute value of the difference reaches a preset error threshold, an adjustment task is generated, including: In an optional implementation, the method by which the PID controller generates the regulation signal includes: The difference, the first difference, and the second difference are extracted through the aforementioned adjustment task; The first coefficient and the second coefficient are calculated based on the ratio of the absolute values ​​of the first difference and the second difference; The first adjustment value is obtained by multiplying the difference by the first coefficient, and the second adjustment value is obtained by multiplying the difference by the second coefficient. An adjustment signal is generated based on the first adjustment value and the second adjustment value.

[0009] In a second aspect, the present invention provides a rolling mill support roll tilting state handling system, comprising: The distance detection module is used to detect the first distance from the operating side hydraulic cylinder to the upper plane of the support roller bearing seat using a first laser rangefinder, and to detect the second distance from the transmission side of the hydraulic cylinder to the upper plane of the support roller bearing seat using a second laser rangefinder. The task generation module is used to calculate the difference between the first distance and the second distance. If the absolute value of the difference reaches a preset error threshold, an adjustment task is generated. The task execution module is used to send the adjustment task to the PID controller, so that the PID controller generates adjustment signals for the speed control valves on both sides of the support roller based on the adjustment task.

[0010] In one optional embodiment, the base of the first laser rangefinder is mounted on the lower surface of the horizontal platform of the operating side hydraulic cylinder, and the detection beam of the first laser rangefinder is perpendicular to the lower surface of the horizontal platform and points to the upper plane of the support roller bearing seat; the base of the second laser rangefinder is mounted on the lower surface of the horizontal platform of the transmission side hydraulic cylinder, and the detection beam of the second laser rangefinder is perpendicular to the lower surface of the horizontal platform and points to the upper plane of the support roller bearing seat.

[0011] In an optional implementation, both the first laser rangefinder and the second laser rangefinder are connected to the controller via a signal amplifier and an analog-to-digital converter.

[0012] Thirdly, a terminal is provided, including: Processor, memory, among which, This memory is used to store computer programs. The processor is used to retrieve and run the computer program from memory, causing the terminal to perform the terminal method described above.

[0013] Fourthly, a computer storage medium is provided, wherein instructions are stored therein, which, when executed on a computer, cause the computer to perform the methods described in the above aspects.

[0023] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0025] The key terms used in this invention will be explained below.

[0026] In process control, the PID controller (also known as a PID regulator), which controls based on the proportional (P), integral (I), and derivative (D) of the deviation, is the most widely used type of automatic controller. It has advantages such as simple principle, ease of implementation, wide applicability, independent control parameters, and relatively simple parameter selection. Furthermore, it can be theoretically proven that for typical process control objects—those with "first-order lag + pure lag" and "second-order lag + pure lag"—the PID controller is an optimal control method.

[0027] The rolling mill support roll tilting state processing method provided in this embodiment of the invention is executed by computer equipment, and correspondingly, the rolling mill support roll tilting state processing system runs in the computer equipment.

[0028] Figure 1 This is a schematic flowchart illustrating a method according to an embodiment of the present invention. Wherein, Figure 1 The executing entity can be a rolling mill support roll tilting state handling system. Depending on different requirements, the order of steps in this flowchart can be changed, and some steps can be omitted.

[0029] like Figure 1 As shown, the method includes: Step 110: Use a first laser rangefinder to detect the first distance from the hydraulic cylinder on the operating side to the upper plane of the support roller bearing seat, and use a second laser rangefinder to detect the second distance from the transmission side of the hydraulic cylinder to the upper plane of the support roller bearing seat. Step 120: Calculate the difference between the first distance and the second distance. If the absolute value of the difference reaches a preset error threshold, an adjustment task is generated. Step 130: The adjustment task is sent to the PID controller so that the PID controller generates adjustment signals for the speed control valves on both sides of the support roller based on the adjustment task.

[0030] To facilitate understanding of the present invention, the following description further illustrates the method for handling the tilted state of the mill support rolls provided by the present invention, based on the principle of the method and the process of handling the tilted state of the mill support rolls in the embodiments.

[0031] Specifically, the methods for handling the tilted state of the rolling mill support rolls include: S1. Use a first laser rangefinder to detect the first distance from the hydraulic cylinder on the operating side to the upper plane of the support roller bearing seat, and use a second laser rangefinder to detect the second distance from the transmission side of the hydraulic cylinder to the upper plane of the support roller bearing seat.

[0032] The base of the first laser rangefinder is mounted on the lower surface of the horizontal platform of the operating side hydraulic cylinder, and the detection beam of the first laser rangefinder is perpendicular to the lower surface of the horizontal platform and points towards the upper plane of the support roller bearing seat. The base of the second laser rangefinder is mounted on the lower surface of the horizontal platform of the transmission side hydraulic cylinder, and the detection beam of the second laser rangefinder is perpendicular to the lower surface of the horizontal platform and points towards the upper plane of the support roller bearing seat. The support roller bearing seat has a symmetrical structure at both ends. Figure 2 This is a schematic diagram of the installation of a rangefinder at one end. In the diagram, the upper surface of the AGC hydraulic cylinder 1 is a horizontally fixed-height plane. The laser rangefinder 3 is vertically installed below the upper plane of the AGC hydraulic cylinder 1. By detecting its position relative to the upper surface of the support roller bearing seat 2, the laser rangefinder 3 can detect the relative position (Hd or Ho) of the support roller in real time. Both the first and second laser rangefinders are connected to the controller via signal amplifiers and analog-to-digital converters.

[0033] S2. Calculate the difference between the first distance and the second distance. If the absolute value of the difference reaches a preset error threshold, an adjustment task is generated.

[0034] The difference between the latest first distance and the second distance is calculated periodically. If the absolute value of the difference reaches a preset error threshold, an adjustment task is generated. The adjustment task includes the difference, the first difference between the latest first distance and the previously acquired first distance, and the second difference between the latest second distance and the previously acquired second distance. If the absolute value of the difference does not reach the preset error threshold, the difference is ignored.

[0035] Specifically, the following steps are included: (1) Data collection and preprocessing: First, the system needs to periodically (e.g., every second, every minute, or as set according to specific needs) collect data on the first and second distances from sensors or data sources.

[0036] The collected data is preprocessed, including but not limited to noise reduction, filtering, outlier detection and removal, to ensure the accuracy and reliability of the data.

[0037] (2) Calculate the latest difference: After each data collection, immediately calculate the difference (denoted as Delta_new) between the latest first distance (D1_new) and the second distance (D2_new), i.e., Delta_new = D1_new - D2_new.

[0038] At the same time, the timestamp of each calculation is recorded for subsequent analysis.

[0039] (3) Error threshold judgment: The absolute value of Delta_new is compared with the preset error threshold (denoted as Threshold).

[0040] If |Delta_new|>= Threshold, it indicates that the difference between the two distances has reached a level that requires attention, and the system should process it further.

[0041] (4) Generate adjustment tasks: When the difference exceeds the error threshold, the system generates an adjustment task. This task contains not only the current difference Delta_new, but also two additional pieces of information: The first difference (denoted as Diff1) is the difference between the latest first distance D1_new and the first distance D1_prev collected previously, i.e., Diff1 = D1_new - D1_prev.

[0042] The second difference (denoted as Diff2) is the difference between the latest second distance D2_new and the previously acquired second distance D2_prev, i.e., Diff2 = D2_new - D2_prev.

[0043] These differences help analyze the causes and trends of distance changes, providing a basis for subsequent adjustment measures.

[0044] S3. The adjustment task is sent to the PID controller so that the PID controller generates adjustment signals for the speed control valves on both sides of the support roller based on the adjustment task.

[0045] The difference, the first difference, and the second difference are extracted from the adjustment task; a first coefficient and a second coefficient are calculated based on the ratio of the absolute values ​​of the first difference and the second difference; the product of the difference and the first coefficient is calculated to obtain a first adjustment value, and the product of the difference and the second coefficient is calculated to obtain a second adjustment value; an adjustment current signal is generated based on the first adjustment value H1 and the second adjustment value H2.

[0046] Methods for generating regulating current signals include: The first adjustment value H1 and the second adjustment value H2 are converted into electrical signals.

[0047] In one specific embodiment, the following steps are included: (1) Extract the difference: Extract the latest difference Delta_new (i.e. the difference between the first distance and the second distance) directly from the adjustment task.

[0048] (2) Calculate the absolute values ​​of the first and second differences: Calculate the absolute values ​​of Diff1 and (the difference between the latest first distance and the first distance collected previously) and Diff2 (the difference between the latest second distance and the second distance collected previously), respectively, because in practical applications, the distance may increase or decrease, and what is needed is the magnitude of the change.

[0049] (3) Calculate the first and second coefficients: Set the first coefficient K1 and the second coefficient K2 based on the ratio of the absolute values ​​of Diff1 and Diff2. This ratio can be set according to the specific needs and design of the system. For example, if the system is more sensitive to changes in the first distance, K1 may be set larger than K2. The calculation method is as follows: ; ; (4) Calculate the first adjustment value and the second adjustment value: Multiply the calculated first coefficient K1 and second coefficient K2 by the difference Delta_new to obtain the first adjustment value H1 and the second adjustment value H2 respectively: H1 = K1 × Delta_new and H2 = K2 × Delta_new; These two adjustment values ​​reflect the result of adjusting the difference based on the relative importance of the two distance changes.

[0050] (5) Applying PID control to generate current signals: In control systems, PID (proportional-integral-derivative) controllers are typically used to adjust current or other control quantities to achieve the desired target. However, for the sake of simplicity, here we assume that some form of "adjustment" or "proportional" control is used directly to generate the current signal. However, in actual industrial applications, PID control is more common and complex.

[0051] Assume Hd and Ho are the target heights (or positions) on the operating side and the transmission side, respectively, while H1 and H2 are the adjustment values ​​we calculated.

[0052] The calculated Id and Io current signals are sent to the corresponding actuators (such as motor drivers) to adjust the position or speed of the operating side and the transmission side, thereby reducing or eliminating the difference between the two distances.

[0053] In another embodiment of the present invention, the error elimination process is simplified, specifically as follows: Figure 3 As shown: Calculate the height difference ΔH between the two sides, where ΔH is a positive number. Generate an adjustment electrical signal based on the height difference between the two sides, including: PID(HDS-△H / 2)=△Id; PID(HOS+△H / 2)=△Io; Where HDS is the actual height on the operating side and HOS is the actual height on the transmission side.

[0054] After the adjustment electrical signal is executed, the height of the operating side of the support roller is updated to △Sd, and the height of the drive side of the support roller is updated to △So.

[0055] In some embodiments, the mill support roll tilt state processing system may include multiple functional modules composed of computer program segments. The computer programs for each program segment in the mill support roll tilt state processing system may be stored in the memory of a computer device and executed by at least one processor to perform (see details). Figure 1 (Description) Function for handling the tilting state of the mill support rolls.

[0056] In this embodiment, the mill support roll tilt state handling system can be divided into multiple functional modules according to its functions, such as... Figure 4 As shown. The functional modules of system 400 may include: a distance detection module 410, a task generation module 420, and a task execution module 430. The module referred to in this invention is a series of computer program segments that can be executed by at least one processor and perform a fixed function, and which are stored in memory. In this embodiment, the functions of each module will be described in detail in subsequent embodiments.

[0057] The distance detection module is used to detect the first distance from the operating side hydraulic cylinder to the upper plane of the support roller bearing seat using a first laser rangefinder, and to detect the second distance from the transmission side of the hydraulic cylinder to the upper plane of the support roller bearing seat using a second laser rangefinder. The task generation module is used to calculate the difference between the first distance and the second distance. If the absolute value of the difference reaches a preset error threshold, an adjustment task is generated. The task execution module is used to send the adjustment task to the PID controller, so that the PID controller generates adjustment signals for the speed control valves on both sides of the support roller based on the adjustment task.

[0058] Optionally, as an embodiment of the present invention, the base of the first laser rangefinder is mounted on the lower surface of the horizontal platform of the operating side hydraulic cylinder, and the detection beam of the first laser rangefinder is perpendicular to the lower surface of the horizontal platform and points to the upper plane of the support roller bearing seat; the base of the second laser rangefinder is mounted on the lower surface of the horizontal platform of the transmission side hydraulic cylinder, and the detection beam of the second laser rangefinder is perpendicular to the lower surface of the horizontal platform and points to the upper plane of the support roller bearing seat.
