[0002] In order to obtain the intermediate billet with good temperature in modern advanced hot rolling production line, the coil box is usually used on the delay roller between rough rolling and flying shear. The coil box rolls the intermediate billet from rough rolling into a coil at the coiling station. The coil box is hollow, and the strip steel is tightly fitted together based on the hollow coil diameter, and then uncoiled. The coil box retaining needle is an important part of the uncoiling station equipment. During the uncoiling process, it ensures that the coiled tail is smoothly unfolded and enters the pinch roller without folding without affecting the subsequent flying shear tail cutting.

[0003] In the related art, the holding needle must be opened to the maximum position before uncoiling. This position is measured by a flow position sensor. However, due to the large deviation, a proximity switch installed at the maximum position must be used to correct the deviation and ensure that the initial value of the holding needle is accurate. However, there is no alarm function in this process, which can easily lead to scrap steel during the uncoiling process because of the inability to detect faults in time (large deviation of the flow position sensor or abnormality of the proximity switch).

[0033] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings, but it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present disclosure.

[0034] As described in the background technology, in order to obtain an intermediate billet with good temperature on a modern advanced hot rolling production line, a coil box is usually used on the delayed roller between the rough rolling and the flying shear. The coil box rolls the intermediate billet from the rough rolling into a coil at the coiling station, and then reversely unwinds the steel coil at the unwinding station and sends it to the flying shear and finishing mill. On the one hand, the coil box must handle the data exchange and speed matching between the rough rolling and finishing rolling, and on the other hand, the position matching between the various roller systems when the steel coil is transmitted in the coil box. The coil box is hollow, and the strip steel is tightly fitted together based on the hollow coil diameter.

[0035] Figure 1 A conceptual diagram of a related technology provided by an embodiment of the present invention. Figure 1 As shown in the upper part, during the uncoiling process, when the uncoiling diameter reaches the position close to the hollow coil diameter, the hydraulic cylinder drives the insertion of retaining pins on both sides of the hollow coil diameter of the steel coil to flatten the curled part of the steel coil tail to prevent the uncoiling machine from folding the curled tail to form a double tail, which affects the subsequent flying shear shearing. As an important part of the uncoiling station equipment, the coil box retaining pin ensures that the curled tail is smoothly unfolded and enters the pinch roller without folding during the uncoiling process without affecting the subsequent flying shear tail shearing.

[0036] like Figure 1As shown in the lower part, before the steel is uncoiled, the retaining needle of the coil box should be opened to the maximum position, that is, after the previous steel uncoil, the retaining needle is opened to the maximum position away from the steel to be uncoiled. The measured value of this position can be measured by the flow position sensor. The flow sensor obtains the measured value of the maximum position by detecting the amount of oil flowing through the hydraulic cylinder. Since the measured value has deviations, the proximity switch installed at the maximum position can also be used to correct the deviation and position to ensure the accuracy of the initial value (i.e., the maximum position) of the retaining needle, so as to prepare for the uncoiling of the next piece of steel coil and ensure the accuracy of the insertion of the retaining needle during the uncoiling process. During use, it was found that the relevant technology lacked an alarm function, and could not promptly detect abnormal problems of the retaining needle caused by proximity switches, mechanical jams or hydraulics.

[0037] The present invention provides a fault detection method, device, electronic device and storage medium for steel unwinding processing. Specifically, a first time is obtained, the first time represents the theoretical time for a holding pin to reach a target position from a working position, the working position is the position of the holding pin when assisting steel unwinding processing, and the target position is the waiting position of the holding pin when non-steel unwinding processing is performed; after the holding pin completes the steel unwinding processing, after the first time, it is determined whether there is a target signal, the target signal represents that the target switch senses the holding pin, and the target switch is set at the target position; if there is a target signal, it is considered that the holding pin has reached the target position; if there is no target signal, an alarm signal representing that the steel unwinding processing has failed is output. In this way, the holding pin open position proximity switch signal is compared with the effective simulated holding pin action time, and when the specified time for the signal to arrive is exceeded, an alarm is output, which can solve the problem of scrap steel caused by the lack of alarm function in the related art during the steel unwinding processing (large deviation of the flow position sensor or abnormal proximity switch).

[0038] In addition, in the related art, when the proximity switch signal is abnormal, the holding needle cannot be properly corrected and positioned when it is opened to the maximum position. In the embodiment of the present invention, after the holding needle completes the steel unwinding process and the first time has passed, the current position of the holding needle can be obtained, and the correction and positioning process is performed for the current position of the holding needle. The theoretical time that represents the holding needle reaching the target position from the working position is used to correct and position the maximum position of the holding needle, which can solve the problem that the plate coil box holding needle cannot complete the correction and positioning function when the proximity switch signal is abnormal in the related art to a certain extent.

[0039] Further, in an embodiment of the present invention, if the target switch is not located at the target position, it can be considered that the target switch caused the steel unwinding process to fail, such as the target switch falling or the device's own signal abnormality. After determining that the target switch caused the alarm, while contacting personnel to solve the problem, the normal operation of the next steel unwinding process can be monitored through on-site monitoring as usual (the abnormality of the target switch does not affect the movement of the holding needle, and thus does not affect the next steel unwinding process). Compared with the related art, when the proximity switch signal is abnormal, although the actual position has a deviation, it meets the unwinding condition, but the return value exceeds the range, resulting in the problem of unwinding not meeting the scrap steel condition. The embodiment of the present invention uses whether the first time after the unwinding process is used as the basis for judging whether the unwinding condition is met. When the target switch is abnormal, the steel unwinding can be continued through manual monitoring and other methods, reducing the impact of the proximity switch on the steel unwinding process and improving steel production efficiency.

[0040] It should be understood that the fault detection method for steel uncoiling provided in the embodiment of the present invention can be executed by a target device. The target device can be a programmable logic controller (PLC) capable of driving a holding needle. The target device can be one electronic device or multiple electronic devices that cooperate with each other to execute. The electronic device can be a server, such as an independent physical server, a server cluster composed of multiple servers, and a cloud server capable of cloud computing.

[0041] The technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0042] Figure 2 A flow chart of a method for detecting a fault in steel uncoiling provided by an embodiment of the present invention. Figure 2 As shown, the fault detection method for steel uncoiling provided by the present invention includes steps 210 to 240.

[0043] Step 210, obtaining a first time, wherein the first time represents a theoretical time for the holding needle to reach a target position from a working position, wherein the working position is a position of the holding needle when assisting in steel uncoiling, and the target position is a waiting position of the holding needle when performing non-steel uncoiling.

[0044] In the embodiment of the present invention, the target position may be the "maximum position" mentioned above, that is, the position where the needle is in a waiting state during the non-steel unwinding process (for example, Figure 1The lower part holds the needle in the hydraulic cylinder. The working position can be the position of the needle during the steel uncoiling process (e.g. Figure 1 The upper part, part of the holding needle leaves the hydraulic cylinder and inserts the steel to be uncoiled. Figure 1 The first time may be a theoretical time for the needle to move from the working position to the target position after the steel uncoiling process is completed.

[0045] In an embodiment of the present invention, an implementation method of obtaining the first time in step 210 may include the following steps: obtaining N movement times, where the movement time is the time taken to move the holding needle from the working position to the target position once; and obtaining the first time based on the N movement times.

[0046] In an embodiment of the present invention, the moving time taken for the holding needle to move from the working position to the target position once N times can be observed and recorded in advance. The target can obtain N moving times by external input, and can also record the moving time of the holding needle each time through the target device itself, and automatically organize it. After obtaining N moving times, the first time can be obtained based on the N moving times, for example, the average of the N moving times can be used as the first time, and the median of the N moving times can also be used as the moving time. In addition, the average (or median) of the N moving times can be further processed, such as multiplying by a certain coefficient or adding a certain time, so that the holding needle has enough time to reach the target position from the working position.

[0047] In the embodiment of the present invention, after the first time is obtained, step 220 may be performed to wait for the time length indicated by the first time after the holding needle completes the steel uncoiling process.

[0048] Step 220, after the holding needle completes the steel uncoiling process, it is determined whether there is a target signal after the first time has passed, the target signal indicating that the target switch senses the holding needle and the target switch is set at the target position.

[0049] In the embodiment of the present invention, the target switch may be a proximity switch in the related art, or may be other switches that can sense whether there is an object (a holding pin in the embodiment of the present invention) around and can generate and send relevant sensing signals. The target switch can be set at the target position (such as Figure 1 to confirm whether the holding needle returns to the target position.

[0050] In the embodiment of the present invention, during the steel uncoiling process, real-time monitoring and analysis can be performed through the screen. When there is no steel to be uncoiled on the holding pin, it can be considered that the holding pin has completed the steel uncoiling process. The target device can start timing after the holding pin completes the steel uncoiling process, and after the first time has passed, it can be determined whether there is a target signal. If there is a target signal, step 230 can be executed; if there is no target signal, step 240 can be executed.

[0051] In step 230, if the target signal exists, it is considered that the holding needle reaches the target position.

[0052] In the embodiment of the present invention, if there is a target signal, that is, the target switch at the target position detects the existence of the holding needle, it can be considered that the holding needle has reached the target position and the next steel uncoiling process instruction can be waited.

[0053] Step 240: If the target signal does not exist, an alarm signal indicating that a failure has occurred in the steel uncoiling process is output.

[0054] In the embodiment of the present invention, after the first time has passed, the holding needle should theoretically reach the target position from the working position. If there is no target signal, it is considered that a fault has occurred in the steel uncoiling process, and an alarm signal indicating that the steel uncoiling process has failed is output, so that on-site staff can view the picture through a camera, or confirm on-site, and make timely corrections to minimize the impact on subsequent steel uncoiling processes.

[0055] In the embodiment of the present invention, the alarm signal may be in the form of sound and light, or in the form of text. The content of the alarm signal may be the time difference between the arrival time of the target signal (which may be continuously waited after the first time has passed after the steel uncoiling process is completed) and the first time, or may be the arrival time of the target signal itself, etc., which is not specifically limited in the embodiment of the present invention.

[0056] In the embodiment of the present invention, in order to confirm the fault more quickly, if there is no target signal, it can be determined by monitoring or on-site confirmation by personnel whether the target switch is in the target position. If the target switch is in the target position, it is determined that the holding pin causes the steel unwinding process to fail; if the target switch is not in the target position, it is determined that the target switch causes the steel unwinding process to fail.

[0057] In the embodiment of the present invention, if the target switch is located at the target position, it can be considered that the holding needle itself has a fault, such as mechanical blocking or hydraulic oil leakage, thereby affecting the steel uncoiling process. After determining that the holding needle device itself has a fault, the relevant personnel can be contacted to solve it as soon as possible, and after the problem is solved, step 210 can be re-executed to obtain a new first time, so that the new first time corresponds to the new holding needle device, which is more accurate.

[0058] In the embodiment of the present invention, if the target switch is not located at the target position, it can be considered that the target switch causes the steel uncoiling process to fail, such as the target switch falling off or the device's own signal abnormality. After determining that the target switch causes the alarm, while contacting personnel to resolve the problem, the normal operation of the next steel uncoiling process can be monitored through on-site monitoring as usual (the abnormality of the target switch does not affect the movement of the holding needle, and thus does not affect the next steel uncoiling process).

[0059] In the embodiment of the present invention, after the alarm signal appears, the operation of the coil box can be manually monitored. If it is confirmed that only the proximity switch has fallen, the alarm can be temporarily turned off, and the alarm function can be activated again after the proximity switch is restored after the roll is changed or the machine is stopped. Compared with the related art, when the proximity switch signal is abnormal, although the actual position has a deviation, the unwinding condition is met, but the return value is out of range, resulting in the problem of unwinding not meeting the conditional scrap steel. The embodiment of the present invention uses whether the first time has passed after the unwinding process as the basis for judging whether the unwinding condition is met. When the target switch is abnormal, the steel unwinding can be continued through manual monitoring and other methods, reducing the influence of the proximity switch on the steel unwinding process and improving the steel production efficiency.

[0060] The present invention provides a fault detection method for steel unwinding processing, obtains a first time, the first time represents the theoretical time for the holding needle to reach the target position from the working position, the working position is the position of the holding needle when assisting the steel unwinding processing, and the target position is the waiting position of the holding needle when the non-steel unwinding processing is performed; after the holding needle completes the steel unwinding processing, after the first time, determine whether there is a target signal, the target signal represents that the target switch senses the holding needle, and the target switch is set at the target position; if there is a target signal, it is considered that the holding needle reaches the target position; if there is no target signal, an alarm signal representing that the steel unwinding processing fails is output. In this way, the holding needle opening position proximity switch signal is compared with the effective simulated holding needle action time, and when the specified time of the signal arrival is exceeded, an alarm is output, which can solve the problem of scrap steel caused by the lack of alarm function in the related art during the steel unwinding processing (large deviation of the flow position sensor or abnormal proximity switch).

[0061] In the embodiment of the present invention, Figure 1 As shown, the holding needle is in the hydraulic cylinder and driven by the hydraulic cylinder. Accordingly, the target device may be a programmable logic controller (PLC) capable of driving the hydraulic cylinder. After obtaining the first time in step 210, a target instruction may be issued to the hydraulic cylinder, and the target instruction indicates that the holding needle is in the target position.

[0062] In the embodiment of the present invention, the target device can continuously send target instructions to the hydraulic cylinder, and after receiving the target instructions, the hydraulic cylinder can Figure 1 As shown in the lower part, the needle is kept at the target position (i.e., Figure 1 maximum position on the .

[0063] In the embodiment of the present invention, in order to enable the holding needle to fully return to the target position under the instruction of the target instruction. In the embodiment of the present invention, before determining whether there is a target signal in step 230, after the holding needle completes the steel uncoiling process and the first time has passed, a second time may pass, and the second time is the error time for waiting for the target signal. The second time can be obtained based on the first time, or it can be manually preset in advance.

[0064] In step 220, after the holding needle completes the steel uncoiling process and the first time has passed, the current position of the holding needle can be obtained; and a deviation correction and positioning process is performed on the current position of the holding needle.

[0065] In the embodiment of the present invention, each time the holding needle completes the steel uncoiling process and after the first time (or the first time plus the second time) has passed, the current position of the holding needle can be obtained, and the deviation between the current position of the holding needle and the target position can be determined, and the deviation correction and positioning processing can be performed in time for the current position of the holding needle. If the deviation is too large, the deviation correction and positioning processing can be performed in time for the current position of the holding needle, such as re-obtaining the first time or confirming whether the holding needle itself has a fault. If the deviation is within the preset range, it can be considered that the holding needle is in a normal state.

[0066] In order to better understand the fault detection method for steel uncoiling provided by the embodiment of the present invention, an example is given. It should be understood that the example is not limiting. Figure 3 A conceptual diagram of a fault detection method for steel uncoiling processing provided by an embodiment of the present invention.

[0067] like Figure 3 As shown, in an embodiment of the present invention, the following processing steps may be included:

[0068] 1) Analyze the time taken for the holding needle to open, that is, the time taken for the holding needle to return to the initial position after unwinding is completed (that is, the first time mentioned above, or the sum of the first time and the second time);

[0069] 2) For control optimization, the holding needle opening time is used to simulate the holding needle opening to the full position for the maximum position correction;

[0070] 3) Determine the time difference between the simulation time and the arrival time of the real signal (i.e., the target signal) of the proximity switch (i.e., the target switch) as the alarm value and output an alarm;

[0071] 4) Create corresponding alarm functions on the steel rolling operation screen;

[0072] 5) Simulation test to confirm that the equipment functions meet the requirements of the solution;

[0073] 6) Rolling test and put into use.

[0074] Starting from the role of the proximity switch in the control of the holding needle and the reasons why the holding needle does not meet the unwinding conditions, the curve analysis found that the time taken for the opening process of the holding needle, that is, the time from the holding needle being fully inserted to the maximum position (the limit position of the hydraulic cylinder at the proximity switch), is unchanged. This fixed time is used as the correction and positioning signal for the holding needle to return to the maximum position. If the proximity switch signal returns abnormally beyond this fixed time, it can be used as an alarm information for timely feedback (appropriately adjust the time deviation as the alarm output), and the on-site holding needle action position and proximity switch status are confirmed in time, which solves the problem of not being able to correct the position of the holding needle when it returns to the maximum position only because of the abnormal proximity switch signal, and the accumulation of periodic deviations causing the unwinding conditions to be not met, resulting in scrap steel. On the other hand, this solution can timely and effectively discover the problem of mechanical jamming or hydraulic oil leakage causing the holding needle to fail to return to the initial position normally.

[0075] In the embodiment of the present invention, by simulating the arrival of the opening time of the holding needle and comparing it with the original proximity switch signal, the abnormal output alarm function can timely discover the fault and further determine the proximity switch, mechanical jamming and hydraulic faults. In addition, by simulating the arrival of the opening time point of the plate coil box holding needle to replace the original proximity switch signal to correct the maximum position of the holding needle, the function of not affecting the continuous unwinding production of the plate coil box can be realized if only the proximity switch signal is abnormal.

[0076] The fault detection method for steel uncoiling provided by the embodiment of the present invention adopts the arrival of the plate coil box holding needle opening time point to replace the original proximity switch's correction and positioning function for the holding needle's maximum position, and outputs an alarm function technology by comparing with the original proximity switch signal, which has the following advantages: 1. The correction and positioning function of the holding needle can still be guaranteed when the proximity switch signal is abnormal; 2. The holding needle opening time is compared with the proximity switch signal, and an alarm is output in the event of an abnormality to confirm that normal rolling can still be carried out without affecting the holding needle opening in place, thereby changing the original problem of failure to timely discover the problem in abnormal situations, resulting in scrap steel, and the problem of production suspension caused by the proximity switch problem requiring replacement of the proximity switch.
