[0002] In order to obtain a good temperature intermediate billet on a modern advanced hot continuous rolling production line, a coil box is usually used on the delay roller between rough rolling and flying shears. The coil box winds the intermediate billet from rough rolling into a coil at the coiling station, and the coil box is hollow, and the strip steel is tightly fitted together based on the hollow coil diameter, and then uncoiling is performed.

[0003] In the related art, the retaining needle is opened to the maximum position before uncoiling, and this position is measured by a flow position sensor, but due to a large deviation, a proximity switch installed at the maximum position is used for deviation correction and positioning to ensure the accuracy of the initial value of the retaining needle.

[0033] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. It is to be understood, however, that the description is merely exemplary and is not intended to limit the scope of the present disclosure.

[0034] As described in the background, in order to obtain a good temperature intermediate billet on a modern advanced hot continuous rolling production line, a coil box is usually used on the delay roller between rough rolling and flying shear. The coil box winds the intermediate billet from rough rolling into a coil at the coiling station, and then reversely unwinds the steel coil to send it into the flying shear and finishing rolling unit at the uncoiling station. The coil box needs to handle the data exchange and speed matching between rough rolling and finishing rolling on the one hand, and the position matching between the various roller systems when the steel coil is conveyed in the coil box on the other hand. The coil of 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 for an embodiment of the present application is shown in FIG. 5. Figure 1 As shown in the upper half, during the uncoiling process, when the uncoiling coil diameter reaches a position close to the hollow coil diameter, the holding needles driven by hydraulic cylinders are inserted on both sides of the hollow coil diameter of the steel coil to flatten the coiled tail part of the steel coil, preventing the uncoiler from folding the coiled tail to cause double tails, affecting the subsequent flying shear cutting. The holding needles of the coil box, as an important part of the uncoiling station equipment, ensure that the coiled tail is smoothly unfolded without folding into the pinch roll during the uncoiling process without affecting the subsequent flying shear tail cutting.

[0036] As shown in FIG. 6, the holding needles of the coil box are inserted on both sides of the hollow coil diameter of the steel coil to flatten the coiled tail part of the steel coil, preventing the uncoiler from folding the coiled tail to cause double tails, affecting the subsequent flying shear cutting. Figure 1As shown in the lower half, before the steel uncoiling process, the holding needle of the coil box is opened to the maximum position, that is, after the previous steel uncoiling process, the holding needle is opened to the maximum position away from the steel to be uncoiled, and the measurement value of this position can be measured by the flow position sensor. The flow sensor obtains the measurement value of the maximum position by detecting the oil flow through the hydraulic cylinder, and due to the deviation of the measurement value, the proximity switch installed at the maximum position can also be used for deviation correction to ensure the accuracy of the initial value (that is, the maximum position) of the holding needle, to prepare for the next steel coil taking and ensure the accuracy of the insertion of the holding needle during the uncoiling process. It is found in use that the related art lacks an alarm function and cannot timely discover abnormal problems of the holding needle caused by the proximity switch, mechanical jamming or hydraulic pressure.

[0037] The present application provides a steel uncoiling process fault detection method, device, electronic equipment and storage medium, specifically, a first time is obtained, the first time represents a theoretical time for the holding needle to reach a target position from a working position, the working position is the position of the holding needle during the steel uncoiling process, and the target position is a waiting position of the holding needle during non-steel uncoiling process; after the first time elapses after the holding needle completes the steel uncoiling process, it is determined whether there is a target signal, the target signal represents that the target switch senses the holding needle, and the target switch is arranged at the target position; if the target signal exists, it is considered that the holding needle reaches the target position; if the target signal does not exist, an alarm signal representing that the steel uncoiling process fails is output. In this way, the holding needle opening position proximity switch signal is compared with the effective simulated holding needle action time, when the signal comes beyond the specified time, an alarm is output, which can solve the problem that in the related art, because of the lack of an alarm function, the fault (large flow position sensor deviation or proximity switch abnormality) cannot be timely discovered during the steel uncoiling process, thereby causing the problem of scrap steel.

[0038] In addition, in the related art, when the proximity switch signal is abnormal, the holding needle cannot be normally deviated and positioned to the maximum position, and in the embodiment of the present application, after the holding needle completes the steel uncoiling process and the first time elapses, the position where the holding needle is currently located can be obtained, and deviation and positioning processing is performed on the position where the holding needle is currently located. The maximum position of the holding needle is deviated and positioned by using the theoretical time for the holding needle to reach the target position from the working position, which can solve the problem that in the related art, the holding needle of the coil box cannot complete the deviation and positioning function when the proximity switch signal is abnormal.

[0039] Further, in the embodiment of the present application, if the target switch is not located at the target position, it can be considered that the target switch causes the failure of this time of steel uncoiling processing, such as the target switch falling or the abnormal signal of the equipment itself, etc. After determining that the target switch causes this time of alarm, the personnel can be contacted to solve the problem, and the normal operation of the next steel uncoiling processing can also be monitored as usual through the on-site monitoring (the abnormality of the target switch does not affect the movement of the holding needle, and further does not affect the next steel uncoiling processing). Compared with the related art, when the proximity switch signal is abnormal, the actual position is deviated, but the uncoiling condition is met, but the return value exceeds the range, resulting in the problem that the uncoiled scrap does not meet the condition. The embodiment of the present application can continue the steel uncoiling through manual monitoring and the like when the target switch is abnormal, reduce the influence of the proximity switch on the steel uncoiling processing, and improve the steel production efficiency.

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

[0041] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be 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 can not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0042] Figure 2 A flowchart of a steel uncoiling processing failure detection method provided by an embodiment of the present application is shown in FIG. 1. As shown in FIG. 1, the steel uncoiling processing failure detection method provided by the present application includes steps 210 to 240. Figure 2

[0043] In step 210, a first time is obtained, the first time representing a theoretical time for the holding needle to reach a target position from a working position, the working position being a position of the holding needle when assisting the steel uncoiling processing, and the target position being a waiting position of the holding needle when not in the steel uncoiling processing.

[0044] In the embodiment of the present application, the target position can be the "maximum position" described above, that is, the position of the holding needle in the waiting state when not in the steel uncoiling processing (for example, the position of the holding needle when not in the steel uncoiling processing is shown in FIG. 2). Figure 1 ​the lower half, keeping the needle in the hydraulic cylinder position). The working position can be the position of keeping the needle when the steel is uncoiled (for example Figure 1 the upper half, part of the needle is kept away from the hydraulic cylinder, inserted into the steel to be uncoiled, Figure 1 not shown in the figure). The first time can be the 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 application, one implementation of step 210 for obtaining the first time can include the following steps: obtaining N moving times, the moving time being the time for the needle to move from the working position to the target position once; and obtaining the first time based on the N moving times.

[0046] In an embodiment of the present application, the moving time for the needle to move from the working position to the target position once can be observed and recorded N times in advance. The target can obtain the N moving times through external input, or can record the moving time of the needle each time by the target device itself and automatically arrange. After obtaining the 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 taken as the first time, or the median of the N moving times can be taken as the moving time, in addition, the average (or median) of the N moving times can be further processed, for example, multiplied by a certain coefficient or increased by a certain time, so that the needle has enough time to move from the working position to the target position.

[0047] In an embodiment of the present application, after obtaining the first time, step 220 can be executed, which waits for a time length indicated by the first time after the needle completes the steel uncoiling process.

[0048] Step 220 determines whether there is a target signal after the first time after the needle completes the steel uncoiling process, the target signal representing that the target switch senses the needle, and the target switch being arranged at the target position.

[0049] In an embodiment of the present application, the target switch can be a proximity switch in the related art, or can be other switches capable of sensing whether there is a certain object (the needle in an embodiment of the present application) around and capable of generating and sending related sensing signals. The target switch can be arranged at the target position (as shown in the figure), for confirming whether the needle returns to the target position. Figure 1

[0050] ​In the embodiment of the present application, during the steel uncoiling process, the picture can be used to monitor and analyze in real time. When the holding needle is not holding the steel to be uncoiled, it can be considered that the holding needle has completed the steel uncoiling process. The target device can start timing after the holding needle completes the steel uncoiling process. After further passing the first time, it can be determined whether there is a target signal. If there is a target signal, step 230 can be performed; if there is no target signal, step 240 can be performed.

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

[0052] In the embodiment of the present application, if there is a target signal, that is, the target switch at the target position detects the presence of the holding needle, it is considered that the holding needle reaches the target position, and the next indication of the steel uncoiling process can be waited for.

[0053] In step 240, if there is no target signal, an alarm signal representing that the steel uncoiling process fails is output.

[0054] In the embodiment of the present application, after the first time, the holding needle should theoretically reach the target position from the working position. If there is no target signal, it is considered that a failure occurs in the steel uncoiling process, and an alarm signal representing that the steel uncoiling process fails is output, so that the on-site staff can view the picture through the camera or confirm on site in time to make timely rectification, so as to minimize the impact on the subsequent steel uncoiling process.

[0055] In the embodiment of the present application, the alarm signal can be in the form of sound and light, or in the form of text. The content of the alarm signal can be the time difference between the arrival time of the target signal (after the first time after the steel uncoiling process ends, it can be continuously waited for) and the first time, or the arrival time of the target signal itself, and the like. The embodiment of the present application does not make specific limitation.

[0056] In the embodiment of the present application, in order to make the failure be confirmed faster, if there is no target signal, it can be determined whether the target switch is located at the target position through monitoring or on-site confirmation by personnel. If the target switch is located at the target position, it is determined that the holding needle causes the steel uncoiling process to fail; if the target switch is not located at the target position, it is determined that the target switch causes the steel uncoiling process to fail.

[0057] In the embodiment of the present application, if the target switch is not located at the target position, it can be considered that the target switch causes the failure of this steel uncoiling process, such as the problem of the target switch falling or the abnormal signal of the device itself. After determining that the target switch causes the alarm, relevant personnel can be contacted to solve the problem, and at the same time, 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).

[0058] In the embodiment of the present application, after the alarm signal appears, the operation of the coil box can be monitored by manual mode. If it is confirmed that only the proximity switch falls, the alarm can be temporarily closed, and the alarm function can be put into operation again after the proximity switch is restored during the roll changing or downtime. Compared with the related art, when the proximity switch signal is abnormal, the actual position has a deviation, but the uncoiling condition is met, but the return value exceeds the range, resulting in the problem of scrap steel that does not meet the uncoiling condition. According to whether the first time is passed after the uncoiling process as a basis for judging whether the uncoiling condition is met, the embodiment of the present application can continue the steel uncoiling through manual monitoring and other modes when the target switch is abnormal, reduce the influence of the proximity switch on the steel uncoiling process, and improve the steel production efficiency.

[0059] In the embodiment of the present application, after the alarm signal appears, the operation of the coil box can be monitored by manual mode. If it is confirmed that only the proximity switch falls, the alarm can be temporarily closed, and the alarm function can be put into operation again after the proximity switch is restored during the roll changing or downtime. Compared with the related art, when the proximity switch signal is abnormal, the actual position has a deviation, but the uncoiling condition is met, but the return value exceeds the range, resulting in the problem of scrap steel that does not meet the uncoiling condition. According to whether the first time is passed after the uncoiling process as a basis for judging whether the uncoiling condition is met, the embodiment of the present application can continue the steel uncoiling through manual monitoring and other modes when the target switch is abnormal, reduce the influence of the proximity switch on the steel uncoiling process, and improve the steel production efficiency.

[0060] The present application provides a fault detection method for steel uncoiling process, acquires a first time, the first time represents the theoretical time of the holding needle from the working position to the target position, the working position is the position of the holding needle assisting the steel uncoiling process, and the target position is the waiting position of the holding needle in the non-steel uncoiling process; after the holding needle completes the steel uncoiling process, whether there is a target signal is determined, the target signal represents that the target switch senses the holding needle, and the target switch is arranged 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 uncoiling process fails is output. In this way, the holding needle opening position proximity switch signal is compared with the effective simulation holding needle action time, and when the signal comes out of the specified time, an alarm is output, which can solve the problem of scrap steel caused by the failure to discover the fault (large position sensor deviation or proximity switch abnormality) in time due to the lack of alarm function in the related art during the steel uncoiling process.

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

[0062] In the embodiment of the present application, the target device can continuously issue target instructions to the hydraulic cylinder. After receiving the target instruction, the hydraulic cylinder can make the holding needle reach the target position (i.e., the maximum position on Figure 1 , as shown in the lower half of the figure). Figure 1

[0063] In the embodiment of the present application, in order to make the holding needle fully return to the target position under the indication of the target instruction. In the embodiment of the present application, after the holding needle completes the steel uncoiling process and the first time elapses, a second time, which is an error time for waiting for the target signal, can elapse before it is determined in step 230 whether the target signal exists. The second time can be obtained according to the first time, or it can be a fixed time preset by a person in advance.

[0064] In step 220, after the holding needle completes the steel uncoiling process and the first time elapses, the position where the holding needle currently locates can be obtained; and the position where the holding needle currently locates is subjected to deviation correction and bit setting.

[0065] In the embodiment of the present application, after the holding needle completes the steel uncoiling process and the first time (or the first time plus the second time) elapses each time, the position where the holding needle currently locates can be obtained, and the deviation between the position where the holding needle currently locates and the target position can be determined, and the position where the holding needle currently locates is subjected to deviation correction and bit setting in a timely manner. If the deviation is too large, the position where the holding needle currently locates can be subjected to deviation correction and bit setting in a timely manner, for example, the first time is reacquired or it is determined whether the holding needle itself has a fault. If the deviation is within a preset range, it can be considered that the holding needle is in a normal state.

[0066] In order to better understand the steel uncoiling process fault detection method provided by the embodiment of the present application, examples are given, and it should be understood that the examples are not limiting. Figure 3 A conceptual diagram of a steel uncoiling process fault detection method provided by the embodiment of the present application.

[0067] As shown in Figure 3 , in the embodiment of the present application, the following processing steps can be included:

[0068] ​1) analysis of the time for which the holding pin is open, i.e. the time for which the unwinding is completed and the holding pin returns to the initial position (i.e. the first time described above, or the sum of the first time and the second time);

[0069] 2) control optimization, using the holding pin opening time to simulate the holding pin opening to the maximum position of the correction bias position;

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

[0071] 4) making corresponding alarm functions for the rolling operation screen;

[0072] 5) simulation test, determining that the device function meets the requirements of the scheme;

[0073] 6) rolling test, and putting into use.

[0074] By analyzing the function of the proximity switch in the holding pin control and the fact that the holding pin does not meet the unwinding condition, it is found that the opening process of the holding pin, i.e. the time for the holding pin to completely insert into the opening to the maximum position (i.e. the limit position of the hydraulic cylinder at the proximity switch), is constant. This fixed time is used as the correction bias position signal of the holding pin returning to the maximum position. When the proximity switch signal abnormally returns beyond this fixed time, it can be used as an alarm information for timely feedback (adjusting the time deviation as an alarm output), and the on-site holding pin action position and the proximity switch situation are confirmed in time, which solves the problem that the holding pin cannot be corrected to the bias position due to the abnormal proximity switch signal, and the periodic deviation accumulation causes the holding pin to not meet the unwinding condition and results in scrap steel. On the other hand, through this solution, mechanical jamming or hydraulic oil leakage problems that cause the holding pin to not return to the initial position normally can be found in time and effectively.

[0075] In the embodiment of the present application, by comparing the simulation holding pin opening time with the original proximity switch signal, an abnormal alarm function is outputted, and the proximity switch, mechanical jamming and hydraulic failure, etc. are found in time. In addition, by simulating the arrival of the holding pin opening time point of the coil box to replace the original proximity switch signal for the correction bias position function of the holding pin at the maximum position, the function of not affecting the coil box to continue unwinding production due to only the abnormal proximity switch signal is realized.

[0076] The fault detection method for steel uncoiling processing provided by the embodiment of the present application has the following advantages: 1. The deviation correction bias function of the holding needle can be ensured when the proximity switch signal is abnormal; 2. The alarm output function technology is compared with the original proximity switch signal, and the holding needle opening is in place, and the abnormality is output, and the normal rolling is ensured, the problem of waste steel caused by the original abnormal situation cannot be found in time, and the problem of shutdown caused by the replacement of the proximity switch due to the proximity switch problem is solved.
