Alloy wire drawing refers to the process of gradually thinning a metal material by passing it through a die under the action of a tensile force.

[0003] In the traditional monitoring process of alloy wire drawing, it usually relies on regular inspections or manual monitoring, and cannot make dynamic adjustments based on real-time data (for example, when the aperture of the die becomes larger due to wear, the resistance on the wire decreases, the tension drops, and if not adjusted in time, the diameter of the drawn wire will be too thick), thus affecting the quality of the finished product. Summary of the Invention

[0055] In the related art, an alloy wire is a wire made by combining two or more metal elements and is usually used in various industrial fields, especially in industries such as electrical, electronic, and communication. Alloy wire drawing refers to the process of gradually thinning a metal material by passing it through a die under the action of a tensile force.

[0056] In the traditional monitoring process of alloy wire drawing, it usually relies on regular inspections or manual monitoring and cannot make dynamic adjustments based on real-time data (for example, when the aperture of the die becomes larger due to wear, the resistance on the wire decreases and the tension drops. If not adjusted in time, the diameter of the drawn wire will be too thick), thus affecting the quality of the finished product.

[0057] To solve the above problems, the embodiments of this application provide an online monitoring method and device for the tension of alloy wire drawing.

[0058] In this method, not only the drawing speed information of the alloy wire, the wear degree information of the drawing die, the current tension information, and the current diameter of the alloy wire are obtained, but also the influence degree of the instability of the tension during the alloy wire drawing process on the drawing quality is considered. When it is recognized that the tension fluctuation value exceeds the preset tension fluctuation value, it can actively calculate and send the alloy wire diameter information to the alloy wire drawing device to guide the device to make adjustments to achieve the target diameter, which helps to avoid the problem that the quality of the finished product is affected due to the inability to make dynamic adjustments based on real-time data.

[0059] The online monitoring method for the tension of alloy wire drawing provided by the embodiments of this application can be applied to an online monitoring device for the tension of alloy wire drawing. At this time, the online monitoring device for the tension of alloy wire drawing is the execution subject of the online monitoring method for the tension of alloy wire drawing provided by the embodiments of this application. The embodiments of this application do not impose any restrictions on the specific type of the online monitoring device for the tension of alloy wire drawing.

[0060] For example, an on-line monitoring device for the drawing tension of an alloy wire may include an on-line monitoring device for the drawing tension of an alloy wire (e.g., an integrated on-line monitoring device for drawing tension, an intelligent drawing monitoring device, etc.), and a control device electrically connected to the on-line monitoring device for the drawing tension of the alloy wire. The on-line monitoring device for the drawing tension of the alloy wire may include sensors (such as a tension sensor, a laser speed measurement sensor, a laser measurement sensor), a surface roughness meter (for detecting the roughness of the die surface), etc. The control device may calculate based on the data obtained by the on-line monitoring device for the drawing tension of the alloy wire to determine the alloy wire diameter information, and send the alloy wire diameter information to the alloy wire drawing device.

[0061] For example, the control device may be a single-chip microcomputer, a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a desktop computer, a computing device, or a computer connected to a wireless modem, a laptop computer, a handheld communication device, a handheld computing device, etc.

[0062] To better understand the on-line monitoring method for the drawing tension of an alloy wire provided in the embodiments of the present application, the following provides an exemplary introduction to the specific implementation process of the on-line monitoring method for the drawing tension of an alloy wire provided in the embodiments of the present application.

[0063] Figure 1 The schematic flowchart of the on-line monitoring method for the drawing tension of an alloy wire provided in the embodiments of the present application is shown. The on-line monitoring method for the drawing tension of an alloy wire includes:

[0064] S100, obtaining monitoring information. Among them, the monitoring information includes the drawing speed information of the alloy wire, the wear degree information of the drawing die, the current tension information, and the current diameter of the alloy wire. The current diameter of the alloy wire is the real-time diameter of the alloy wire at the current moment during the drawing process.

[0065] It can be understood that the current tension information may include the tension information at each moment, the average tension information within a period of time.

[0066] Exemplarily, the speed can be calculated by measuring the time when the alloy wire passes through a certain point with a laser speed measurement sensor. The probe of the surface roughness meter can be slid onto the die surface, and the probe measures the surface profile by moving to record the changes in different heights to calculate the surface roughness. For example, on a specific measurement line, the probe records the height of each point, and the surface roughness is calculated by the height of each point, such as Zi is the height value relative to the measurement line (the height of each measurement point), n is the total number of measurement points, and Ra is the roughness. It is also possible to use an industrial camera to take real-time pictures of the mold and analyze the wear condition in combination with image processing algorithms. The tension can be calculated by measuring the force on the roller through a tension sensor, such as a strain gauge type or a magnetic powder type, set on the tension roller or the turning roller of the wire drawing machine. The diameter of the alloy wire can be measured by the laser beam of a laser measurement sensor.

[0067] With such settings, data can be obtained in real time to provide data support for subsequent adjustments.

[0068] S200, obtain the current tension fluctuation value. Among them, the current tension fluctuation value is used to reflect the influence degree of the instability of the tension of the alloy wire during the wire drawing process on the wire drawing quality.

[0069] It can be understood that the current tension fluctuation value can be obtained based on the wire drawing speed information, the wear degree information of the wire drawing die, the current tension information, the current diameter and wear degree information of the alloy wire.

[0070] Exemplarily, the wire drawing tension, wire drawing speed, alloy wire diameter and wear degree can be obtained at time t. Then, calculate the change in tension, average tension and quantization information. For example, the change in tension △T = T(t) - T(t - △t), where T(t - △t) represents the tension value at △t time units (such as seconds, milliseconds, etc.) before time t. The quantization information Q(t) = k1×v(t) + k2×D(t), where k1 and k1 are empirical indicators that can be determined based on historical data or experiments, v(t) is the current wire drawing speed, and D(t) is the current diameter. Calculate the current tension fluctuation value based on the change in tension, average value, quantization information and wear degree. For example, Among them, (1 - W(t)) represents the wear degree, with 0 being no wear and 1 being maximum wear, and k3 is an adjustment coefficient used to adjust the sensitivity of the fluctuation value.

[0071] With such settings, by monitoring the tension fluctuation in real time, potential problems caused by unstable tension during the wire drawing process can be discovered in a timely manner, thereby providing data support for subsequent adjustment measures and helping to improve the wire drawing quality of the alloy wire.

[0072] In a possible implementation manner, S200, obtain the current tension fluctuation value, including:

[0073] S210, obtain quantization information according to the wire drawing speed information and the current diameter of the alloy wire. Among them, the quantization information is used to reflect the influence degree of the wire drawing speed and the diameter of the alloy wire on the tension fluctuation.

[0074] It can be understood that the quantization information can be calculated based on the drawing speed in the drawing speed information and the diameter of the current alloy wire. For example, the quantization information Q(t) = k1×v(t) + k2×D(t), where k1 and k1 are empirical coefficients that can be determined based on historical data or experiments, v(t) is the current drawing speed, and D(t) is the current diameter.

[0075] With such a setting, the influence of the drawing speed and the alloy wire diameter on the tension fluctuation can be quantified, providing data support for subsequent adjustments.

[0076] S220. Obtain the tension change information based on the current tension information, the quantization information, and the first coefficient.

[0077] It can be understood that the tension change information can be calculated based on the change in tension, the average tension, the quantization information, and the first coefficient in the current tension information. For example, the change in tension △T = T(t) - T(t - △t), where T(t - △t) represents the tension value at △t time units (such as seconds, milliseconds, etc.) before time t. Then

[0078] With such a setting, the influence of multiple physical quantities can be integrated, which helps to improve the accuracy of monitoring, avoiding evaluating the tension fluctuation only with △T and ignoring the problems of speed and diameter on the tension stability.

[0079] S230. Obtain the current tension fluctuation value based on the tension change information, the wear degree information, and the second coefficient.

[0080] It can be understood that the current tension fluctuation value can be calculated based on the tension change information, the wear degree information, and the second coefficient. For example, where (1 - W(t)) represents the wear degree, with 0 being no wear and 1 being maximum wear, and k3 is an adjustment coefficient used to adjust the sensitivity of the fluctuation value.

[0081] With such a setting, by monitoring the tension fluctuation in real time, potential problems caused by unstable tension during the drawing process can be detected in a timely manner, thus providing data support for subsequent adjustment measures and helping to improve the drawing quality of the alloy wire.

[0082] S300. In the case where it is determined that the current tension fluctuation value exceeds the preset tension fluctuation value, determine the alloy wire diameter information based on at least one of the drawing speed information, the wear degree information, the current tension fluctuation value, and the current tension information, and the preset tension fluctuation value.

[0083] It can be understood that in the case where it is determined that the current tension fluctuation value exceeds the preset tension fluctuation value, a correction coefficient can be calculated based on the preset tension fluctuation value, the current tension information, the current tension fluctuation value, and the wear degree information. For example, Among them, It is used to balance instantaneous anomalies. Then, according to the correction coefficient and the wire drawing speed, the adjusted diameter is calculated. For example, Among them, k4 is an empirical constant determined through experiments or historical data, v(t) is the current wire drawing speed, and the higher the speed, the smaller △D (to avoid excessive adjustment caused by too high speed leading to secondary fluctuations). The alloy wire diameter information = D preset + △D, where D preset can be the diameter specified in the process document or the stable diameter before the current fluctuation.

[0084] It should be noted that a "range" can be set as the tension range or operating conditions of the alloy wire. When the current tension is lower than the minimum value of this "range", the system will determine that the wire drawing operation cannot be carried out normally. Even if it is determined that the current tension fluctuation value exceeds the preset tension fluctuation value, the wire drawing operation cannot be carried out normally. Therefore, steps S200, S300, S400, and S500 can be carried out when the current tension is within this "range".

[0085] With such settings, when it is recognized that the tension fluctuation value exceeds the preset tension fluctuation value, the alloy wire diameter information can be actively calculated and sent to the alloy wire drawing equipment to guide the equipment to make adjustments to achieve the target diameter, which helps to avoid the problem that the quality of the finished product is affected due to the inability to make dynamic adjustments based on real-time data.

[0086] In a possible implementation manner, in S300, when it is determined that the current tension fluctuation value exceeds the preset tension fluctuation value, according to at least one of the wire drawing speed information, wear degree information, current tension fluctuation value, and current tension information, and the preset tension fluctuation value, the alloy wire diameter information is determined, including:

[0087] In S310, when it is determined that the current tension fluctuation value exceeds the preset tension fluctuation value, according to the preset tension fluctuation value, current tension information, current tension fluctuation value, and wear degree information, a correction coefficient is obtained.

[0088] It can be understood that when it is determined that the current tension fluctuation value exceeds the preset tension fluctuation value, the correction coefficient can be calculated according to the preset tension fluctuation value, current tension information, current tension fluctuation value, and wear degree information. For example, Among them, It is used to balance instantaneous anomalies.

[0089] With such settings, it helps to more accurately reflect the actual working conditions by integrating multiple parameters. Wear compensation can adapt to the aging of the die to reduce the differences under different working conditions and avoid excessive correction in dynamic adjustment.

[0090] S320. Obtain the adjusted diameter information based on the correction coefficient and the wire drawing speed information.

[0091] It can be understood that the adjusted diameter is calculated according to the correction coefficient and the wire drawing speed. For example, where k4 is an empirical constant determined through experiments or historical data, and v(t) is the current wire drawing speed. The higher the speed, the smaller △D (to avoid excessive adjustment caused by too high a speed, which may lead to secondary fluctuations).

[0092] With such a setting, by adjusting the diameter according to the correction coefficient and the wire drawing speed, the alloy wire drawing equipment can dynamically adjust the diameter of the alloy wire according to the real-time production status, which helps to ensure that the diameter of the alloy wire remains within a predetermined range, thus guaranteeing the quality of the product.

[0093] S330. Superimpose the adjusted diameter information and the preset diameter information to obtain the alloy wire diameter information.

[0094] It can be understood that the alloy wire diameter information = D preset + △D, where D preset can be the diameter specified in the process document or the stable diameter before the current fluctuation.

[0095] With such a setting, when it is recognized that the tension fluctuation value exceeds the preset tension fluctuation value, the alloy wire diameter information can be actively calculated and sent to the alloy wire drawing equipment to guide the equipment to make adjustments to reach the target diameter, which helps to avoid the problem that the quality of the finished product is affected due to the inability to make dynamic adjustments according to real-time data.

[0096] S400. Send the alloy wire diameter information to the alloy wire drawing equipment. The alloy wire diameter information is used to instruct the alloy wire drawing equipment to draw the diameter of the alloy wire to the target diameter.

[0097] It can be understood that the alloy wire diameter information can be sent to the alloy wire drawing equipment by wired means (such as wires, cables) or wireless means (such as Wi-Fi, Bluetooth). After the alloy wire drawing equipment receives the target diameter information, it can draw the diameter of the alloy wire to the target diameter. For example, adjust the aperture of the wire drawing die.

[0098] With such a setting, it can guide the equipment to make adjustments to reach the target diameter, which helps to avoid the problem that the quality of the finished product is affected due to the inability to make dynamic adjustments according to real-time data.

[0099] In a possible implementation manner, the online monitoring method for the alloy wire drawing tension further includes:

[0100] When it is determined that the current tension fluctuation value does not exceed the preset tension fluctuation value, drawing information is generated. The drawing information can be sent to the alloy wire drawing equipment and is used to instruct the alloy wire drawing equipment to draw and maintain the diameter of the alloy wire to the current diameter of the alloy wire, or is used to instruct the alloy wire drawing equipment to draw the diameter of the alloy wire to a specified diameter. The specified diameter is the diameter that the alloy wire is frequently produced under normal wire drawing quality requirements and the tension fluctuation meets the preset conditions, or the specified diameter is the diameter of the fastest production speed of the alloy wire drawing equipment and the tension fluctuation meets the requirements.

[0101] It can be understood that by real-time monitoring of the current tension fluctuation value, if this fluctuation value is less than or equal to the preset tension fluctuation value, it means that the current tension fluctuation meets the expectation, and the step of generating drawing information is entered.

[0102] Case 1: If the current tension fluctuation value meets the preset conditions and the diameter of the alloy wire is already under normal production requirements, an instruction can be generated to require the alloy wire drawing equipment to maintain the diameter of the alloy wire as the current diameter.

[0103] Case 2: When the set specified diameter is the diameter that the alloy wire is frequently produced under normal wire drawing quality requirements and the tension fluctuation meets the preset conditions, and it is obtained that the current tension fluctuation value does not exceed the preset tension fluctuation value and the current diameter is not the specified diameter, drawing information can be generated to instruct the alloy wire drawing equipment to draw the diameter of the alloy wire to the specified diameter. Or, when the set specified diameter is the diameter of the fastest production speed of the alloy wire drawing equipment and the tension fluctuation meets the requirements, and it is obtained that the current tension fluctuation value does not exceed the preset tension fluctuation value and the current diameter is not the specified diameter, drawing information can be generated to instruct the alloy wire drawing equipment to draw the diameter of the alloy wire to the specified diameter.

[0104] Case 3: When it is obtained that the current tension fluctuation value does not exceed the preset tension fluctuation value, drawing information can be generated to instruct the alloy wire drawing equipment to draw and maintain the diameter of the alloy wire to the current diameter of the alloy wire.

[0105] With such a setting, when the tension fluctuation does not exceed the preset value, it is possible to real-time monitor and decide whether to maintain the current diameter, avoiding unnecessary adjustments, thereby maintaining the stable operation of the production process. There is no need to frequently adjust the diameter, avoiding quality fluctuations caused by excessive adjustments.

[0106] In a possible implementation manner, before step S100 of obtaining the monitoring information, the online monitoring method for the drawing tension of the alloy wire further includes:

[0107] S500, when a monitoring signal for a target alloy wire is obtained, determine whether the on-line monitoring device for the wire drawing tension of the alloy wire is in the target mode. Herein, the target mode is a mode capable of obtaining information on the alloy wire drawing device during the wire drawing process.

[0108] It can be understood that the monitoring signal can be a signal to start the task of monitoring the alloy wire. The target mode can be a mode capable of obtaining and analyzing information on the alloy wire drawing device monitored by the sensor during the wire drawing process.

[0109] Exemplarily, it can be determined whether the on-line monitoring device for the wire drawing tension of the alloy wire is in the target mode by means of the indicator light, display screen of the on-line monitoring device for the wire drawing tension of the alloy wire or a dedicated status query command. It is also possible to check the data stream from the sensor to determine whether the data is continuous and conforms to the expected format.

[0110] With such a setting, the mode of the on-line monitoring device for the wire drawing tension of the alloy wire can be quickly identified, providing a data basis for subsequent monitoring.

[0111] S600, when it is determined that the on-line monitoring device for the wire drawing tension of the alloy wire is in the target mode, determine whether the type of the target alloy wire is the same as the type of the previous alloy wire.

[0112] It can be understood that the type of the alloy wire can be the model number of the alloy wire, the alloy composition, etc.

[0113] Exemplarily, it can be determined whether the type of the target alloy wire is the same as the type of the previous alloy wire by manually inputting or scanning a label to input the type of the current alloy wire. It is also possible to obtain the type of the previous alloy wire from the system log and database records, compare the type of the target alloy wire with the previous type, and determine whether they are the same.

[0114] With such a setting, it can be determined whether the target alloy wire currently monitored is the same as the previous alloy wire, providing data support for the subsequent flexible output of monitoring information.

[0115] In a possible implementation manner, S600, when it is determined that the on-line monitoring device for the wire drawing tension of the alloy wire is in the target mode, determining whether the type of the target alloy wire is the same as the type of the previous alloy wire includes:

[0116] When it is determined that the on-line monitoring device for the wire drawing tension of the alloy wire is in the target mode, determine whether the type of the target alloy wire is the same as the type of the previous alloy wire according to the specification information. Herein, when the specification information detected in adjacent monitoring tasks is inconsistent, it is determined that the type of the target alloy wire is different from the type of the previous alloy wire. When the specification information detected in adjacent monitoring tasks is consistent, it is determined that the type of the target alloy wire is the same as the type of the previous alloy wire.

[0117] It can be understood that if the specification information is the same in adjacent monitoring tasks, it is considered that the type of the target alloy wire is the same as the type of the previous alloy wire. If the specification information is different in adjacent monitoring tasks, it is considered that the type of the target alloy wire is different from the type of the previous alloy wire.

[0118] With such a setting, it can be determined whether the currently monitored target alloy wire is the same as the previous alloy wire, providing data support for flexibly outputting monitoring information subsequently.

[0119] S700, when it is determined that the type of the target alloy wire is the same as the type of the previous alloy wire, it is judged according to the mark whether the on-line monitoring device for the wire drawing tension of the alloy wire has performed monitoring in the preset mode in the previous monitoring task. Here, the previous monitoring task is the most recently completed monitoring task before the on-line monitoring device for the wire drawing tension of the alloy wire obtains the monitoring signal. The preset mode is a mode in which information during the wire drawing process of the alloy wire drawing device cannot be obtained.

[0120] It can be understood that the preset mode can be a mode in which information during the wire drawing process of the alloy wire drawing device monitored by the sensor cannot be obtained and analyzed. When the on-line monitoring device for the wire drawing tension of the alloy wire has performed monitoring in the preset mode in the previous monitoring task, a target mark is generated. When the on-line monitoring device for the wire drawing tension of the alloy wire has not performed monitoring in the preset mode in the previous monitoring task, a specified mark is generated. Therefore, it can be judged according to the mark whether the on-line monitoring device for the wire drawing tension of the alloy wire has performed monitoring in the preset mode in the previous monitoring task.

[0121] Exemplarily, when the on-line monitoring device for the wire drawing tension of the alloy wire is adjusted from the preset mode to the target mode and the type of the target alloy wire is the same as the type of the previous alloy wire, because information during the wire drawing process of the alloy wire drawing device cannot be obtained in the preset mode, in the case of being adjusted from the preset mode to the target mode, the monitoring information in the previous preset mode (i.e., no information) may be output, so information during the wire drawing process of the alloy wire drawing device cannot be obtained. That is, in Scenario 1, the on-line monitoring device for the wire drawing tension of the alloy wire is adjusted from the preset mode to the target mode, but as long as the type of the target alloy wire is the same as the type of the previous alloy wire, the on-line monitoring device for the wire drawing tension of the alloy wire will output the previous monitoring information. Therefore, in the scenario where the mode of the on-line monitoring device for the wire drawing tension of the alloy wire is continuously adjusted, the output monitoring information may not meet the requirements. The following is a detailed description of this scenario.

[0122] For example, for the first time, a monitoring task is performed on the alloy wire x, and the on-line monitoring device for the wire drawing tension of the alloy wire is in the target mode, and the monitoring information of the alloy wire x is output. Then, the on-line monitoring device for the wire drawing tension of the alloy wire is adjusted from the target mode to the preset mode, and a monitoring task is performed on the alloy wire y. Since the data of the sensor cannot be obtained and analyzed, the monitoring information of the alloy wire y cannot be output. When the on-line monitoring device for the wire drawing tension of the alloy wire is adjusted to the target mode and still performs a monitoring task on the alloy wire y, although the monitoring task will be performed when adjusted to the target mode, because it is the previous alloy wire y, in order to avoid wasting monitoring resources, the previous monitoring information will be output (for example, for the first time, the diameter information of the alloy wire x is obtained during the monitoring task of the alloy wire x, and if the diameter information of the alloy wire x still needs to be obtained the second time, then the monitoring task can be skipped, and the diameter information of the alloy wire x obtained for the first time can be filled into the output information corresponding to the second monitoring task), that is, the monitoring information of the alloy wire x is output (because the monitoring information of the alloy wire y could not be output in the previous preset mode, so the monitoring information output this time is the previous monitoring information of the alloy wire x. As shown in Table 1, although the second time is the previous time of the third time, since the information corresponding to the second time is empty, this second time is skipped, that is, the first time is the previous time of the third time). This will result in the output monitoring information not being the monitoring information corresponding to the actual alloy wire.

[0123] Table 1

[0124] First time Monitoring information of alloy wire x Second time Empty Third time Monitoring information of alloy wire x

[0125] With such a setting, the mode of the on-line monitoring device for the wire drawing tension of the alloy wire can be effectively distinguished by the mark, providing data support for the data flexibly output during subsequent mode switching.

[0126] S800, when it is determined that the type of the target alloy wire is the same as the type of the previous alloy wire, and it is determined that the on-line monitoring device for the wire drawing tension of the alloy wire has performed monitoring in the preset mode during the previous monitoring task, real-time monitoring is performed on the target alloy wire to determine the monitoring information corresponding to the target alloy wire in the current monitoring task. Among them, the monitoring information includes the tension value of the target alloy wire at different stages or the current diameter information of the target alloy wire.

[0127] Exemplarily, the alloy wire x is monitored for the first time, and the on-line monitoring device for the wire drawing tension of the alloy wire is in the target mode, and the monitoring information corresponding to the alloy wire x is output. Then, the on-line monitoring device for the wire drawing tension of the alloy wire is adjusted from the target mode to the preset mode, and a monitoring task is performed on the alloy wire y. Since the data of the sensor cannot be obtained and analyzed, the monitoring information of the alloy wire y cannot be output. When the on-line monitoring device for the wire drawing tension of the alloy wire is adjusted to the target mode and still performs a monitoring task on the alloy wire y, because the type of the target alloy wire is the same as that of the previous alloy wire, but the on-line monitoring device for the wire drawing tension of the alloy wire has performed monitoring in the preset mode, the previous monitoring information will not be output, but the target alloy wire will be monitored in real time to determine the monitoring information corresponding to the target alloy wire in this monitoring task.

[0128] With such a setting, it is possible to avoid the problem that when the mode of the on-line monitoring device for the wire drawing tension of the alloy wire is continuously adjusted and the type of the target alloy wire is the same as that of the previous alloy wire, the output monitoring information is not the monitoring information corresponding to the actual alloy wire.

[0129] In a possible implementation manner, the method for on-line monitoring of the wire drawing tension of the alloy wire further includes:

[0130] S801, when the on-line monitoring device for the wire drawing tension of the alloy wire has performed monitoring in the preset mode in the previous monitoring task, generate a target mark.

[0131] It can be understood that after each task ends, the data will be recorded in a log or a database. For example, the monitoring mode (whether it is the preset mode) and the execution status (whether monitoring has been performed) can be recorded. If it is confirmed that the monitoring task has been performed in the preset mode, the system can generate a target mark to indicate that the monitoring task has been completed in the preset mode.

[0132] With such a setting, by systematically recording the monitoring mode and the execution status, the execution situation of each monitoring task can be conveniently tracked, providing an important basis for subsequent data analysis.

[0133] S802, when the on-line monitoring device for the wire drawing tension of the alloy wire has not performed monitoring in the preset mode in the previous monitoring task, generate a specified mark.

[0134] It can be understood that after each task ends, the data will be recorded in a log or a database. For example, the monitoring mode (whether it is the preset mode) and the execution status (whether monitoring has been performed) can be recorded. If it is confirmed that the monitoring task has not been performed in the preset mode, the system can generate a specified mark to indicate that the monitoring task has been completed in the target mode.

[0135] With such settings, by systematically recording the monitoring mode and execution status, it is convenient to track the execution of each monitoring task, providing an important basis for subsequent data analysis.

[0136] In a possible implementation, the on-line monitoring method for the drawing tension of alloy wires further includes:

[0137] When it is determined that the type of the target alloy wire is inconsistent with the type of the previous alloy wire, real-time monitoring is performed on the target alloy wire to determine the monitoring information corresponding to the target alloy wire in this monitoring task.

[0138] It can be understood that when it is determined that the type of the target alloy wire is inconsistent with the type of the previous alloy wire, it means that the strategy of outputting the previous monitoring information to avoid wasting monitoring resources will not occur. Therefore, real-time monitoring can be performed on the target alloy wire to determine the monitoring information corresponding to the target alloy wire in this monitoring task.

[0139] With such settings, the monitoring information of the target alloy wire can be captured in a timely manner, ensuring that the obtained monitoring data has higher accuracy and reliability.

[0140] In a possible implementation, the on-line monitoring method for the drawing tension of alloy wires further includes:

[0141] When it is determined that the type of the target alloy wire is the same as the type of the previous alloy wire, and it is determined that the on-line monitoring device for the drawing tension of the alloy wire has not performed monitoring in the preset mode in the previous monitoring task, the monitoring information corresponding to the alloy wire in the previous monitoring task is determined as the monitoring information corresponding to the target alloy wire in this monitoring task.

[0142] Exemplarily, for the first time, a monitoring task is performed on alloy wire x, and the on-line monitoring device for the drawing tension of the alloy wire is in the target mode, and the monitoring information of alloy wire x is output. Then, the on-line monitoring device for the drawing tension of the alloy wire is still in the target mode, and a monitoring task is performed on alloy wire y, and the monitoring information of alloy wire y is output. When the on-line monitoring device for the drawing tension of the alloy wire is still in the target mode and still performs a monitoring task on alloy wire y, in order to avoid wasting monitoring resources, the previous monitoring information (i.e., the monitoring information of alloy wire y output in the second task) will be output, that is, the monitoring information corresponding to the alloy wire in the previous monitoring task is determined as the monitoring information corresponding to the target alloy wire in this monitoring task.

[0143] With such settings, avoiding repeated monitoring processes can significantly save time and the monitoring resources used. By outputting the existing monitoring information, the required data can be quickly obtained.
