[0002] Continuous casting is an important link in modern steel manufacturing, and the casting machine is an important equipment in continuous casting. Continuous casting is the link to realize the transformation of steel from "liquid to solid", and it has high requirements on the control difficulty and control accuracy of the casting machine equipment. The roll gap value is an important parameter of the casting machine. In the actual production process, it is necessary to control the roll gap value of the casting machine to remain stable. If the roll gap value fluctuates greatly, it will cause bulging, center porosity, center segregation, liquid level fluctuation and other problems in the steel slab, affecting the quality of the steel slab. Therefore, the roll gap value of the casting machine can be measured in real time by an online roll gap detection device. However, due to problems with the continuous casting operation process, the detection device may repeatedly collect data during the detection inside the casting machine, thereby reducing the effectiveness of the detection data obtained by the detection device. Therefore, how to improve the effectiveness of the detection data of the detection equipment is a technical problem that needs to be solved urgently. Summary of the Invention

[0030] In order to enable those skilled in the art to better understand the present application, the casting machine roll gap and roll gap detection proposed in the present application will first be briefly explained.

[0031] Continuous casting is an important part of modern steel manufacturing, and the casting machine is an important equipment in continuous casting. Continuous casting is the link to achieve the transformation of steel from "liquid to solid", and it has high requirements for the control difficulty and control accuracy of the casting machine equipment. The roll gap value is an important parameter of the casting machine. In the actual production process, it is necessary to control the roll gap value of the casting machine to remain stable. If the roll gap value fluctuates greatly, it will cause bulging, center looseness, center segregation, liquid level fluctuation and other problems in the steel slab, affecting the quality of the steel slab. Therefore, the roll gap value of the casting machine can be measured in real time by an online roll gap detection device. However, due to problems with the continuous casting operation process, the detection device may repeatedly collect data during the detection process inside the casting machine, thereby reducing the effectiveness of the detection data obtained by the detection device. Therefore, how to improve the effectiveness of the detection data of the detection device is a technical problem that needs to be solved urgently. Based on this, the present application proposes a detection data preprocessing method for an online casting machine roll gap detection device to improve the efficiency of the casting machine roll gap value detection.

[0032] Next, we will combine Figure 1 The detection data preprocessing method of the online casting machine roll gap detection equipment proposed in this application is explained in detail.

[0033] See also Figure 1 , shows a flow chart of a method for preprocessing detection data of an online caster roll gap detection device in one embodiment of the present application, which can be executed by a device with a computing and processing function, such as Figure 1 As shown, the method may include at least steps 110 to 130:

[0034] Step 110: Acquire angle data of the detection device, and determine position information and movement information of the detection device in the casting machine based on the angle data.

[0035] Step 120: Based on the position information and the movement information, the detection data acquired by the detection device is divided into redundant data and valid data.

[0036] Step 130: extract the valid data from the detection data to obtain target detection data, and the target detection data is used to calculate the roll gap value of the casting machine roll gap.

[0037] In the present application, the angle data can be obtained by an angle sensor provided inside the detection device.

[0038] In the present application, the position information may specifically include the position of the detection device in the casting machine, and the movement information may specifically include the movement mode of the detection device in the casting machine.

[0039] In the present application, the angle data of the detection equipment is acquired in real time to determine the position information and movement information of the detection equipment in the casting machine, and then the detection data acquired by the detection equipment is divided into valid data and redundant data through the position information and the movement information. In this way, the detection data acquired by the detection equipment when it moves normally in the casting machine can be effectively extracted, thereby improving the validity of the detection data of the detection equipment. In addition, by dividing the detection data into valid data and redundant data, and extracting the valid data for calculating the roll gap value of the casting machine roll gap, the total amount of data in the subsequent data processing process can be reduced, thereby improving the validity of the detection data of the detection equipment to a certain extent, thereby improving the efficiency of data processing.

[0040] In the above step 110, the angle data of the detection device is obtained, which can be specifically performed according to the following step 111:

[0041] Step 111 : When the detection device moves from the casting platform to the inside of the casting machine, angle data of the detection device is acquired at a preset frequency until the detection device returns to the casting platform.

[0042] In a specific embodiment of the present application, the movement process of the detection device in the casting machine can be as follows: Figure 2 As shown, see Figure 2 , shows a schematic diagram of the movement of an online casting machine roll gap detection device in an embodiment of the present application in a casting machine, as shown in FIG. Figure 2 As shown, the detection device first moves from the casting platform to the inside of the casting machine (not shown in the figure). After the detection device enters the inside of the casting machine, it will first move in the vertical section inside the casting machine. After passing the vertical section, the detection device will enter the fan-shaped section inside the casting machine and move. During the movement in the fan-shaped section, due to the operating process of the casting machine, the detection device will perform parking movement, reverse movement and movement in repeated sections in the casting machine. After the detection device leaves the fan-shaped section in the casting machine, the detection device will move in the horizontal section in the casting machine until it leaves the inside of the casting machine. After the detection device leaves the inside of the casting machine, it will return to the casting platform.

[0043] In this application, the detection device can be installed at one end of a dummy chain within the casting machine, so that the movement of the dummy chain can drive the detection device to move within the casting machine. During continuous casting, the end of the dummy chain away from the detection device needs to be connected to the casting machine inlet to achieve a sealed condition for the crystallizer. During the connection between the dummy chain and the casting machine inlet, the dummy chain needs to stop and reverse, which causes the detection device to stop and reverse. In addition, due to the length limit of the dummy chain, the stopping and reversing movement of the detection device occurs within the sector inside the casting machine.

[0044] In the present application, the preset frequency may be specifically a detection every 20 milliseconds, or a detection every 50 milliseconds. Depending on actual needs, the preset frequency may also be other parameters, and the present application does not make any specific limitation on this.

[0045] In the present application, the detection device can obtain the angle data at a preset frequency through the angle sensor, and can also obtain the detection data at the same preset frequency, that is, the detection device can obtain detection data each time it obtains angle data.

[0046] In the present application, the angle data of the detection device during its movement inside the casting machine is obtained at a preset frequency to achieve the purpose of real-time monitoring of the position and movement status of the detection device. In this way, the position information and movement information of the detection device can be judged by the angle data, and the detection data can be classified according to the position information and the movement information, which can ultimately effectively improve the effectiveness of the detection data obtained by the detection device.

[0047] In the above step 120, the position information and movement information of the detection device in the casting machine are determined based on the angle data, which can be specifically performed according to the following step 121:

[0048] Step 121: If the angle data of the detection device gradually increases from the first angle to the second angle, it is determined that the detection device is in the process of turning from the casting platform to the inside of the casting machine.

[0049] In the present application, the angle data of the detection device is a first angle when the detection device is horizontally placed on the casting platform.

[0050] In the present application, the first angle may specifically be any angle between 0° and 0.5°, and the second angle may specifically be any angle between 89.5° and 90.5°.

[0051] In this application, please refer to Figure 3, shows a graph showing the change in angle data of an online caster roll gap detection device over time in one embodiment of the present application, such as Figure 3 As shown, the angle data of the detection device gradually increases from the first angle at time T1. l At time T1, the angle data of the detection device increases to the second angle, indicating that the detection device moves from the casting platform to the inside of the casting machine until T l At the moment, the detection device has just entered the vertical section inside the casting machine. Therefore, it can be judged that the detection device has been in operation from the moment T1 to the moment T l It is always in the process of transferring from the casting platform to the inside of the casting machine.

[0052] In this application, the detection device is from time T1 to T l At time T1, the detection device is in the process of being transferred from the casting platform to the inside of the casting machine. During this process, the detection device is located outside the casting machine and has not yet contacted the casting machine roller of the casting machine. Therefore, the detection device can be moved from time T1 to time T2. l The detection data obtained during the time (ie, when the detection device is in the process of moving from the casting platform to the inside of the casting machine) is divided into redundant data, so that the validity of the detection data obtained by the detection device can be improved.

[0053] In the above step 120, the position information and movement information of the detection device in the casting machine are determined based on the angle data, which can be specifically performed according to the following step 122:

[0054] In step 122, if the angle data of the detection device remains at the second angle, it is determined that the detection device moves within the vertical section of the casting machine.

[0055] Please continue to refer to Figure 3 , in T l Time to T o During the time, the angle data of the detection device maintains the second angle unchanged, indicating that the detection device is always in a state perpendicular to the casting platform, that is, the detection device continues to move in the vertical section inside the casting machine.

[0056] In this application, the detection device is in T l Time to T o During the time, the vertical section inside the casting machine continues to move. There is a casting machine roll gap formed by the casting machine rollers in the vertical section of the casting machine. It is necessary to detect the roll gap value of the casting machine roll gap. Therefore, the detection device is at T l Time to T oThe detection data acquired during a time (ie, the detection device continuously moves in the vertical section inside the casting machine) can be classified as valid data, thereby improving the validity of the detection data acquired by the detection device.

[0057] In the above step 120, the position information and movement information of the detection device in the casting machine are determined based on the angle data, which can be specifically performed according to the following steps 123 to 124:

[0058] Step 123: If the angle data of the detection device increases from the second angle to the third angle, it is determined that the detection device moves within the sector of the casting machine.

[0059] Step 124: During the movement of the detection device within the sector of the casting machine, if the angle data of the detection device remains unchanged, it is determined that the detection device has stopped moving within the sector of the casting machine; if the angle data of the detection device gradually decreases, it is determined that the detection device has reversed within the sector of the casting machine.

[0060] In the present application, the third angle may specifically be any angle between 179.5° and 180.5°.

[0061] In the present application, it can be understood that the angle data of the detection device remains unchanged, and the change value of the angle of the detection device can be less than or equal to the preset angle threshold. If the change value of the angle of the detection device is less than or equal to the preset angle threshold, it is determined that the angle data of the detection device remains unchanged, wherein the preset angle threshold can be 0.1°.

[0062] Please continue to refer to Figure 3 , the angle data of the detection device is from T o The second angle gradually increases from the moment T p At time T, the angle data of the detection device increases to the third angle, indicating that the detection device is at o Time to T p At the time, the sector is in motion inside the casting machine.

[0063] Continue to refer to Figure 3 During the movement of the detection device in the sector of the casting machine, the angle data of the detection device is T o Time to T i The angle data of the detection device increases gradually during the T time, indicating that the detection device moves normally in the fan-shaped segment in the casting machine. i Time to T i+jThe detection device remains unchanged within the sector segment of the casting machine, indicating that the detection device stops moving. The angle data of the detection device is T i+j Time to T m The angle data of the detection device increases gradually during the T time, indicating that the detection device moves normally in the fan-shaped segment in the casting machine. m Time to T m+n The value gradually decreases within a certain time, indicating that the detection device is performing a reverse motion in the sector of the casting machine.

[0064] In this application, in T o Time to T i Time, and T i+j Time to T m During the time period T, the detection device moves normally within the sector. Therefore, the detection device moves normally within the sector. o Time to T i The detection data obtained within time, and the detection data obtained at T i+j Time to T m All the detection data acquired within T can be classified as valid data; i Time to T i+j At the time, the detection device stops moving in the sector of the casting machine, so the detection device stops moving at T i Time to T i+j The detection data acquired within time can be divided into redundant data; m Time to T m+n At this moment, the detection device makes a reverse motion in the sector of the casting machine, that is, the detection device moves backward at T m Time to T m+n The casting machine roll gap is repeatedly detected within the time, so the detection equipment is at T m Time to T m+n The detection data acquired within a time period can be divided into redundant data, thereby effectively improving the validity of the detection data acquired by the detection device.

[0065] In the displacement data preprocessing method of the online casting machine roll gap detection device proposed in this application, the method can also be performed according to the following steps 1231 to 1234:

[0066] Step 1231, while the detection device is moving within the sector of the casting machine, record the angle data of the detection device when it starts to reverse within the sector of the casting machine as the angle data for determining the repeated section, wherein the repeated section is the section that the detection device repeatedly passes through when it continues to move forward after reversing within the sector of the casting machine.

[0067] Step 1232: When the detection device is performing reverse movement in the sector of the casting machine, the angle data of the detection device is reduced to the minimum angle data, and the angle data is used as the starting angle data of the repeated section.

[0068] Step 1233, in the process of the angle data of the detection device gradually increasing from the starting angle data to the third angle, traverse the angle data of the detection device, and determine the angle data that is the same as the judgment angle data as the end angle data of the repeated section.

[0069] Step 1234: If the angle data of the detection device increases from the starting angle data to the ending angle data, the detection device moves within the repeated road section.

[0070] Continue to combine Figure 3 , the angle data of the detection device when it starts to do reverse movement in the sector of the casting machine, that is, the detection device at T m The angle data at the moment can be used as the angle data for determining the repeated section; in the process of the detection device making a reverse movement in the sector of the casting machine, when the angle data of the detection device is reduced to the minimum, that is, T as shown in the figure m+n At this moment, it indicates that the reverse movement of the detection device ends and starts to move in the repeated section. The angle data at this moment can be used as the starting angle data of the repeated section. The angle data of the detection device gradually increases from the starting angle data to the third angle, that is, at T m+n Time to T p In the time, the detection device passes through the repeated section and the remaining fan-shaped section inside the casting machine after completing the reverse movement. Therefore, it can be traversed by T m+n Time to T p The angle data within the time is the same as the angle data of the determination angle data as the ending angle data of the repeated section. Figure 3 It can be concluded that the time corresponding to the end angle data is T m ' moment, that is, at T m+n Time to T m ' time, the detection device moves in a repeated section in the casting machine.

[0071] In this application, in T m+n Time to T m ', the detection device moves in the repeated section in the casting machine. At this time, the detection data obtained by the detection device is the data of repeated measurement. Therefore, the detection device can be moved in the repeated section in T m+n Time to T mThe data acquired during the time ' (ie, the detection device moves within the repeated road section) is divided into redundant data, thereby improving the validity of the detection data acquired by the detection device.

[0072] In the above step 120, the position information and movement information of the detection device in the casting machine are determined based on the angle data, which can be specifically performed according to the following step 125:

[0073] In step 125 , if the angle data of the detection device remains at the third angle, it is determined that the detection device is moving within the horizontal section of the casting machine.

[0074] Continue to refer to Figure 3 , in T p Time to T q During the time, the angle data of the detection device remains unchanged at the third angle, indicating that the detection device always remains horizontal when moving in the casting machine, that is, the detection device moves in the horizontal section in the casting machine.

[0075] In this application, in T p Time to T q During the time period T, the detection device moves normally in the horizontal section of the casting machine. Therefore, the detection device moves normally in the horizontal section of the casting machine. p Time to T q The detection data acquired within a time period can be divided into valid data, thereby improving the validity of the detection data acquired by the detection device.

[0076] In the above step 120, the position information and movement information of the detection device in the casting machine are determined based on the angle data, which can be specifically performed according to the following step 126:

[0077] Step 126: If the angle data of the detection device increases from the third angle to the fourth angle, it is determined that the detection device has left the casting machine and returned to the casting platform.

[0078] In the present application, the fourth angle may specifically be any angle between 359.5° and 360°.

[0079] Continue to combine Figure 3 , the angle data of the detection device is from T q The angle gradually increases from the third moment, indicating that the detection device has left the horizontal section inside the casting machine, moved to the outside of the casting machine, and started to move back to the casting platform until T s At this moment, the angle data of the detection device increases to the fourth angle, indicating that the detection device has returned to the casting platform.

[0080] In this application, in T q Time to T s During the time period T, the detection device is in the process of leaving the casting machine and returning to the casting platform, that is, the detection device is located outside the casting machine. Therefore, the detection device is in the process of leaving the casting machine and returning to the casting platform. q Time to T s The detection data acquired within a time period can be divided into redundant data, thereby significantly improving the effectiveness of the detection data acquired by the detection device.

[0081] Based on the technical solution proposed in this application, the angle data of the detection equipment is acquired in real time to determine the position information and movement information of the detection equipment in the casting machine, and then the detection data acquired by the detection equipment is divided into valid data and redundant data through the position information and the movement information. In this way, the detection data acquired by the detection equipment when it moves normally in the casting machine can be effectively extracted, thereby improving the validity of the detection data of the detection equipment. In addition, by dividing the detection data into valid data and redundant data, and extracting the valid data for calculating the roll gap value of the casting machine roll gap, the total amount of data in the subsequent data processing process can be reduced, thereby improving the validity of the detection data of the detection equipment to a certain extent, thereby improving the efficiency of data processing.
