[0003] Currently, due to limitations in equipment configuration, the existing online detection of slab width mainly relies on manual measurement. Because the temperature of hot-delivered slabs is high, it brings problems such as high safety risks and poor measurement accuracy to the measurement work. Furthermore, manual measurement uses tape measures or self-made calipers, which results in large measurement errors and low efficiency. Summary of the Invention

[0032] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention.

[0033] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention.

In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.

[0034] Please combine Figure 1 As shown, the present invention provides an online width measuring device for slabs.

[0035] In one exemplary embodiment of this application, the online width measuring device for slabs includes:

[0036] Roller conveyor 1 is used to convey slab 2;

[0037] The distance detection module is set on both sides of the roller conveyor 1 along the width direction and is used to detect the distance data between the slab 2 on the roller conveyor 1 and the distance detection module.

[0038] The information processing module is electrically connected to the distance detection module. The information processing module is used to receive distance data and calculate the width of the slab 2 based on the distance data.

[0039] In this embodiment, the slab 2 is conveyed via roller conveyor 1. Distance detection modules positioned on both sides of roller conveyor 1 in the width direction collect distance data of the slab 2 in a non-contact manner. The collected distance data is sent to the information processing module, which analyzes and calculates the collected distance data of the slab 2 to obtain the width of the slab 2. The technical solution proposed in this application eliminates the need for manual intervention during the entire online measurement of the slab 2 width, effectively avoiding the risk of personnel being burned by the high-temperature slab 2. Furthermore, the combined algorithm processing of the distance detection module and the information processing module effectively eliminates manual measurement errors and significantly improves the online detection accuracy of the slab 2 width.

[0040] In an exemplary embodiment of this application, the distance detection module includes a first ranging module 3, a second ranging module 4, and a third ranging module 5. The first ranging module 3 and the second ranging module 4 are symmetrically arranged along the width direction of the roller conveyor 1, and the second ranging module 4 and the third ranging module 5 are located on the same side. The second ranging module 4 and the third ranging module 5 are arranged sequentially along the conveying direction of the roller conveyor 1.

[0041] In this embodiment, during daily production, the slab 2 runs on the roller conveyor 1 and may become skewed. Therefore, the distance detection module uses a three-range meter (i.e., the first range meter module 3, the second range meter module 4, and the third range meter module 5) measurement method, and the three range meters are arranged in a right triangle along the roller conveyor 1. The width of the slab 2 is measured using the principle of similar triangles.

[0042] In an exemplary embodiment of this application, the first ranging module 3, the second ranging module 4, and the third ranging module 5 are located at the same horizontal height.

[0043] In this embodiment, by setting the three ranging modules at the same horizontal height, it is ensured that the distance data collected by each module is on the same reference plane, thereby eliminating the measurement dimensional deviation caused by the height difference.

[0044] In an exemplary embodiment of this application, the distance between the first ranging module 3, the second ranging module 4, and the third ranging module 5 along the height direction of the roller conveyor 1 is 150 mm.

[0045] In this embodiment, when the slab 2 is conveyed on the roller conveyor 1, the installation height of the ranging module is 150mm away from the roller conveyor, which can effectively reduce the impact of the slab 2's jump or slight bending on the measurement, thereby ensuring the measurement accuracy.

[0046] Please combine Figure 1 As shown, the present invention provides an online width measurement method for slab 2.

[0047] In an exemplary embodiment of this application, the online width measurement method for the slab 2 includes at least steps S110 to S140, which are described in detail below:

[0048] In step S110, the first ranging module 3 and the second ranging module 4 are arranged symmetrically along the width direction of the roller conveyor 1.

[0049] In step S120, the second ranging module 4 and the third ranging module 5 are arranged on the same side of the roller conveyor 1 along the width direction and arranged sequentially along the transport direction of the roller conveyor 1, so that the first ranging module 3, the second ranging module 4 and the third ranging module 5 form a right triangle.

[0050] In step S130, the distance detection module is started to acquire the distance data between the distance measuring module and the measured slab 2 in real time.

[0051] In step S140, the information processing module receives the distance data acquired in real time by the ranging module, and performs automated calculations on the data using a preset algorithm to obtain the width value of the slab 2.

[0052] In this embodiment, the first ranging module 3 and the second ranging module 4 are symmetrically arranged along the width direction of the roller conveyor 1 to form a baseline spanning both sides of the slab 2. Then, the second ranging module 4 and the third ranging module 5 are arranged sequentially on the same side along the conveying direction, forming a right-angled triangle with the first ranging module 3. The geometric calculations are simplified by utilizing the right-angled side properties. When the slab 2 passes through, the three ranging modules simultaneously collect the distance data L1, L2, and L3 of the slab 2. The information processing module establishes a mathematical relationship between distance and width based on the distances L0 and L between the ranging modules and the principle of similar triangles. It automatically calculates and eliminates the influence of slab 2 skewness, ultimately obtaining an accurate width value, achieving non-contact online precision measurement.

[0053] In an exemplary embodiment of this application, the real-time acquisition of distance data between the distance measuring module and the slab 2 under test by activating the distance detection module includes: the first distance measuring module 3 acquiring the distance L1 from the slab 2 under test to the first distance measuring module 3; the second distance measuring module 4 acquiring the distance L2 from the slab 2 under test to the second distance measuring module 4; and the third distance measuring module 5 acquiring the distance L3 from the slab 2 under test to the third distance measuring module 5.

[0054] In an exemplary embodiment of this application, the distance between the first ranging module 3 and the second ranging module 4 is L0; the distance between the second ranging module 4 and the third ranging module 5 is L.

[0055] In an exemplary embodiment of this application, the information processing module receives distance data acquired in real time by the ranging module and performs automated calculations on the data using a preset algorithm to obtain the width value of the slab 2, including:

[0056] The formula for the preset algorithm is expressed as follows:

[0057] In this embodiment, based on the distance L0 between the first ranging module 3 and the second ranging module 4, the distance L between the second ranging module 4 and the third ranging module 5, and the distance data L1, L2, and L3 collected by the first ranging module 3, the second ranging module 4, and the third ranging module 5, a right-angled triangle geometric model is constructed. Utilizing the principle that corresponding sides of similar triangles are proportional, the formula for calculating the width to eliminate the skewing effect of the slab 2 is derived through the numerical relationship between L0, L and L1, L2, and L3: W=(LL0-LL1-LL2) / √L 2 -(L2-L3) 2

[0058] The information processing module inputs the collected real-time data into the formula to automatically complete the calculation and finally obtain the actual width value of slab 2, thereby achieving accurate measurement of the width of slab 2 and solving the problem of inaccurate measurement caused by the skewing of slab 2 during transportation.

[0059] The working principle involves conveying slab 2 via roller conveyor 1. Distance detection modules positioned on both sides of roller conveyor 1 collect distance data from slab 2 in a non-contact manner. This collected distance data is then sent to an information processing module, which analyzes and calculates the distance data to determine the width of slab 2. The proposed technical solution eliminates the need for manual intervention during the entire online slab 2 width measurement process, effectively avoiding the risk of burns from the high-temperature slab 2. Furthermore, the combined algorithm processing of the distance detection modules and the information processing module effectively eliminates human measurement errors, significantly improving the online detection accuracy of slab 2 width.

[0060] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
