[0023] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0025] The key terms appearing in the present invention are explained below.
[0026] In process control, the PID controller (also known as PID regulator) that controls according to the proportion (P), integral (I) and differential (D) of the deviation is the most widely used automatic controller. It has the advantages of simple principle, easy implementation, wide application, independent control parameters, and relatively simple parameter selection. In addition, it can be proved in theory that for the typical objects of process control - "first-order lag + pure lag" and "second-order lag + pure lag" control objects, the PID controller is an optimal control.
[0027] The method for processing the tilt state of a support roller of a rolling mill provided in an embodiment of the present invention is executed by a computer device, and correspondingly, the system for processing the tilt state of a support roller of a rolling mill runs in the computer device.
[0028] Figure 1 is a schematic flow chart of a method according to an embodiment of the present invention. Figure 1 The execution subject may be a rolling mill support roll tilt state processing system. According to different requirements, the order of the steps in the flow chart may be changed, and some may be omitted.
[0029] like Figure 1 As shown, the method includes: Step 110, using a first laser rangefinder to detect a first distance from the hydraulic cylinder on the operating side to the upper plane of the support roller bearing seat, and using a second laser rangefinder to detect a second distance from the transmission side of the hydraulic cylinder to the upper plane of the support roller bearing seat; Step 120, calculating the difference between the first distance and the second distance, and generating an adjustment task if the absolute value of the difference reaches a preset error threshold; Step 130: 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.
[0030] To facilitate understanding of the present invention, the method for processing the inclination state of the support roller of a rolling mill provided by the present invention is further described below based on the principle of the method for processing the inclination state of the support roller of a rolling mill provided by the present invention and in combination with the process of processing the inclination state of the support roller of a rolling mill in the embodiment.
[0031] Specifically, the method for processing the tilt state of the support roll of the rolling mill includes: S1. Use a first laser rangefinder to detect a first distance from the operating side hydraulic cylinder to the upper plane of the support roller bearing seat, and use a second laser rangefinder to detect a 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 installed on the lower surface of the horizontal platform of the hydraulic cylinder on the operating side, 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 installed on the lower surface of the horizontal platform of the hydraulic cylinder on the transmission side, 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. The support roller bearing seat is a symmetrical structure at both ends. Figure 2 The figure is a schematic diagram of the installation of the rangefinder at one end. In the figure, the upper surface of the AGC hydraulic cylinder 1 is a horizontal plane with a fixed height, and the laser rangefinder 3 is vertically installed below the upper plane of the AGC hydraulic cylinder 1. The laser rangefinder 3 can detect the relative position (Hd or Ho) of the support roller in real time by detecting the position of the upper surface of the support roller bearing seat 2. The first laser rangefinder and the second laser rangefinder are connected to the controller through a signal amplifier and an analog-to-digital signal converter.
[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, generate an adjustment task.
[0034] The difference between the latest first distance and the second distance is calculated regularly; if the absolute value of the difference reaches a preset error threshold, an adjustment task is generated, wherein the adjustment task includes the difference, a first difference between the latest first distance and the first distance collected last, and a second difference between the latest second distance and the second distance collected last; if the absolute value of the difference does not reach the preset error threshold, the difference is ignored.
[0035] The specific steps include: (1) Data collection and preprocessing: First, the system needs to collect data of the first distance and the second distance from a sensor or data source at a regular interval (such as every second, every minute, or according to specific requirements).
[0036] The collected data is preprocessed, including but not limited to denoising, filtering, outlier detection and removal, to ensure the accuracy and reliability of the data.
[0037] (2) Calculate the latest difference: After each data collection, the difference (denoted as Delta_new) between the latest first distance (denoted as D1_new) and the second distance (denoted as D2_new) is immediately calculated, that is, 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 a preset error threshold (denoted as Threshold).
[0040] If |Delta_new|>= Threshold, the difference between the two distances has reached a level that requires attention and the system should proceed further.
[0041] (4) Generate adjustment tasks: When the difference exceeds the error threshold, the system generates a reconciliation task. This task contains not only the current difference Delta_new, but also two additional 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, that is, Diff1 = D1_new - D1_prev.
[0042] The second difference (denoted as Diff2) is the difference between the latest second distance D2_new and the second distance D2_prev collected previously, that is, Diff2 = D2_new - D2_prev.
[0043] These differences help analyze the causes and trends of distance changes and provide a basis for subsequent adjustment measures.
[0044] S3. Sending 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.
[0045] The difference, the first difference and the second difference are extracted from the adjustment task; the first coefficient and the second coefficient are calculated based on the absolute value ratio of the first difference and the second difference; the product of the difference and the first coefficient is calculated to obtain the first adjustment value, and the product of the difference and the second coefficient is calculated to obtain the second adjustment value; and the adjustment current signal is generated based on the first adjustment value H1 and the second adjustment value H2.
[0046] Ways to generate a regulated current signal include: The first adjustment value H1 and the second adjustment value H2 are converted into electrical signals.
[0047] In a specific embodiment, the steps include: (1) Extracting the difference: directly extract the latest difference Delta_new (i.e., the difference between the first distance and the second distance) from the adjustment task.
[0048] (2) Calculate the absolute values of the first difference and the second difference: Calculate the absolute values of Diff1 (the difference between the latest first distance and the first distance collected last) and Diff2 (the difference between the latest second distance and the second distance collected last) respectively. In practical applications, the change in distance may be an increase or a decrease, and what is needed is the magnitude of the change.
[0049] (3) Calculate the first coefficient and the second coefficient: The first coefficient K1 and the second coefficient K2 are set based on the absolute value ratio 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: ; ; (4) Calculating the first adjustment value and the second adjustment value: Using the calculated first coefficient K1 and second coefficient K2, multiplying by the difference Delta_new respectively to obtain the first adjustment value H1 and the second adjustment value H2: H1=K1×Delta_new and H2=K2×Delta_new; The two adjustment values reflect the results of adjusting the difference according to the relative importance of the two distance changes.
[0050] (5) Apply PID control to generate current signal: In control systems, PID (proportional-integral-differential) controllers are usually used to adjust current or other control quantities to achieve the desired target. However, here, in order to simplify the explanation, it is assumed that some form of "regulation" or "proportional" control is directly used to generate the current signal. However, in actual industrial applications, PID control is more common and complex.
[0051] Assume that Hd and Ho are the target heights (or positions) of the operating side and the transmission side respectively, and 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 △H on both sides, △H is a positive number. Generate an adjustment electrical signal based on the height difference on both sides, including: PID(HDS-△H / 2)=△Id; PID(HOS+△H / 2)=△Io; Among them, HDS is the actual height of the operating side, and HOS is the actual height of the transmission side.
[0054] After the adjustment electric signal is executed, the operating side height of the support roller is updated to △Sd, and the driving side height of the support roller is updated to △So.
[0055] In some embodiments, the rolling mill support roller tilt state processing system may include a plurality of functional modules composed of computer program segments. The computer program of each program segment in the rolling mill support roller tilt state processing system may be stored in the memory of a computer device and executed by at least one processor to execute (see Figure 1 Description) The function of processing the tilt state of the rolling mill support roll.
[0056] In this embodiment, the rolling mill support roll tilt state processing system can be divided into multiple functional modules according to the functions it performs, such as Figure 4 As shown. The functional modules of the 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 the present invention refers to a series of computer program segments that can be executed by at least one processor and can complete fixed functions, which are stored in a memory. In this embodiment, the functions of each module will be described in detail in subsequent embodiments.
