Description

Technical Field

[0001] The present invention relates to the technical field of equipment monitoring, and particularly to a monitoring system and a monitoring method for metal wire drawing equipment. Background Art

[0002] Metal wire drawing equipment plays an important role in modern industrial production. With the progress of technology and the continuous change of market demand, the monitoring system of metal wire drawing equipment is also constantly developing and innovating. Metal wire drawing equipment is an important part of the metal processing industry and is widely used in many aspects such as wire and cable manufacturing, steel bar processing, electronics industry, automotive industry, aerospace field, hardware processing, petrochemical industry, plastic industry, and machinery manufacturing. Traditional wire drawing machines usually use dry or wet methods for wire drawing, but there are some problems that cannot be ignored in either method, such as large heat generation of the equipment, easy damage of mechanical components, and low production efficiency.

[0003] Wire drawing equipment is mainly divided into two types: dry wire drawing and wet wire drawing. During dry wire drawing, the metal wire and the reel are not immersed in the coolant, so the heat generation is large, which causes the mechanical components such as internal bearings to be damaged more quickly, affecting the equipment life and production efficiency. While during wet wire drawing, although the heat generation is small, due to the need for a large amount of coolant, it increases the production cost and the risk of environmental pollution. In addition, the monitoring means of traditional wire drawing equipment are relatively backward, mainly relying on manual detection and experience judgment, and it is difficult to achieve real-time and accurate control. Summary of the Invention

[0004] The present invention aims at the technical problems existing in the prior art and provides a monitoring system for metal wire drawing equipment.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: A monitoring system for metal wire drawing equipment, comprising:

[0006] An operating status monitoring module: obtaining the operating status of the metal wire drawing equipment and the operating parameters of each component of the equipment in real time;

[0007] A production data monitoring module: monitoring the key data in the production process in real time, analyzing the production data, and displaying the analysis results on the monitoring interface in real time, and triggering an alarm when the standard is not met;

[0008] An anomaly detection module: detecting the operating status of the wire drawing equipment and performing trend analysis, and determining the type of equipment failure based on the trend analysis.

[0009] In a preferred embodiment, the operating status monitoring module establishes a telecommunication connection with the device control terminal. For the operating parameters of different device components, including speed, temperature, and vibration parameters, sensors are used to collect the operating parameters of different components, including speed sensors, temperature sensors, and vibration sensors. By installing the speed sensor on the rotating component of the wire drawing device, the signal of the incremental encoder is output using a shielded cable, and the real-time pulse signal output by the encoder is counted. Substitute the collected pulse number N, encoder circumference C, encoder resolution P, and acquisition time t into the speed calculation formula. The specific calculation formula is as follows:

[0010]

[0011] Among them, v represents the speed, the rotational speed of the rotating component is calculated based on the calculation formula, the temperature T of the motor housing is obtained through the temperature sensor, and the vibration amplitude of the motor is obtained by the vibration amplitude sensor installed on the motor. The data signal output by the vibration amplitude sensor is discretely sampled. Based on the measurement time T, the sampling points a1, a2,..., a within the measurement time T are obtained n , and based on the collected sampling points, the vibration amplitude calculation formula is used for calculation. The specific calculation formula is as follows:

[0012]

[0013] Among them, A RMS represents the vibration amplitude, n represents the number of sampling points, and a i represents the acceleration value of the i-th sampling point.

[0014] In a preferred embodiment, the production data monitoring module monitors the production data during the production process of the metal wire drawing device in real time, including the tension, size, and output of the wire. Based on the production data, the stability during the production process and the consistency of product quality are ensured. The tension signal is collected from the tension sensors installed at the inlet, outlet, and intermediate links of the wire drawing machine, and is converted into a standard signal through a tension transmitter. Based on the analysis of the standard signal, including calculating the average value and standard deviation of the tension, the stability of the tension is evaluated. For n tension measurement values T1, T2,..., T m , the specific calculation formulas for the tension average value and the standard deviation σ T are as follows:

[0015]

[0016] Among them, T iDenote the i-th tension measurement value. The diameter and ovality of the metal wire are measured using a laser dimensional measurement sensor. The laser sensor emits a laser beam towards the wire, and the size information of the wire is calculated based on the time difference of the received reflected light. The deviation of the size is calculated based on the size information, and it is determined whether the size is within the qualified range. Assume that the laser beam emitted by the laser sensor is perpendicularly incident on the surface of the metal wire, and the propagation speed of the laser in the medium is P v , assume the time difference from laser emission to reception is Δt, that is, the distance S traveled by the laser is S = P v ×Δt. This distance is the length of the laser passing through the wire diameter twice, that is, the specific calculation formula for the wire diameter D is as follows:

[0017]

[0018] Based on the diameter D of the wire i and the standard diameter D0 set according to the order, calculate the deviation of the diameter. The specific calculation formula is as follows:

[0019]

[0020] Among them, ΔD represents the diameter deviation. Compare the diameter deviation with the measured value of the standard quality. When the diameter deviation is greater than the measured value of the standard quality, it is determined that the size parameter does not meet the quality requirements. The production data is collected by installing a counter on the take-up device, recording the number of turns H of the take-up, and calculating the production based on the circumference per of the take-up reel and the cross-sectional area cross of the wire. The specific calculation formula is as follows:

[0021] roduction = H × per × cross

[0022] The statistical analysis results of the production data are displayed in real time on the monitoring interface, including the mean value, standard deviation of the tension, the change range of the size, and the trend chart of the production. When it is detected that the data does not meet the quality standard, a quality alarm is triggered to notify the operator to adjust the equipment and process parameters.

[0023] In a preferred embodiment, the anomaly detection module detects the operating state of the wire drawing equipment, performs trend analysis on the operating state, including speed parameters, temperature parameters, and vibration parameters. Based on the trend analysis, the fault type is marked from the wire drawing equipment. For the speed parameter sequence v1, v2,..., v vm , in order to analyze the trend, select a window size of k, and the simple moving average MA v (n) The specific calculation formula is as follows:

[0024]

[0025] Among them, MA v(n) represents the simple moving average of the speed parameter, k represents the window size for calculating the simple moving average, and based on the simple moving average of the speed parameter, the difference between adjacent moving averages is calculated to determine the trend change of the speed parameter. The specific calculation formula is as follows:

[0026] Δv v (n) = MA v (n) - MA v (n - 1)

[0027] Among them, Δv v (n) represents the change amount of the speed parameter trend change, MA v (n - 1) represents the simple moving average of the speed at position n - 1. When Δv(n) > 0, it indicates that the speed is on the rise; when Δv(n) < 0, it indicates that the speed is on the decline. For the temperature parameter sequence T, T2,..., T tm , calculate the simple moving average of the temperature parameter. The specific calculation formula is as follows:

[0028]

[0029] Among them, MA T (n) represents the simple moving average of the temperature parameter. Based on the simple moving average of the temperature parameter, the difference between adjacent moving averages is calculated to determine the trend change of the temperature. The specific calculation formula is as follows:

[0030] ΔT(n) = MA T (n) - MA T (n - 1)

[0031] Among them, ΔT(n) represents the change amount of the temperature trend change, MA T (n - 1) represents the simple moving average of the temperature parameter at position n - 1. When ΔT(n) > 0, it indicates that the temperature is on the rise; when ΔT(n) < 0, it indicates that the temperature is on the decline. For the vibration parameter sequence A RMS1 , A RMS2 ,..., A RMSm , calculate the simple moving average of the vibration parameter The specific calculation formula is as follows:

[0032]

[0033] Based on the simple moving average of the vibration parameter, calculate the difference between the moving averages to determine the trend change of the vibration parameter. The specific calculation formula is as follows:

[0034]

[0035] Among them, ΔA RMS(n) represents the change trend of temperature parameters, represents the simple moving average of the vibration parameters at position n-1. RMS When (n)>0, it means that the vibration amplitude is on the rise. RMS When (n) < 0, it means that the vibration amplitude is decreasing. When the speed continues to decrease and eventually falls below v vmin , it indicates that the device is gradually losing power. If the temperature continues to rise and exceeds T tmax , it indicates that there is a fault inside the equipment that causes continuous accumulation. When the vibration amplitude continues to rise and exceeds A RMSmax , it indicates that the mechanical parts of the equipment are aggravated by wear and the connections between the parts are loose, resulting in abnormal increase in vibration. When the operating parameters are monitored to exceed the normal range threshold, the system quickly triggers the alarm mechanism and notifies relevant personnel by popping up an alarm window, issuing an audible and visual alarm signal, sending text messages or emails, etc.

[0036] The embodiment of the present invention also provides a monitoring method for a metal wire drawing device, comprising the following steps:

[0037] S101, obtaining the operating status of the metal wire drawing equipment and the operating parameters of each component of the equipment in real time;

[0038] S102, real-time monitoring of key data in the production process, and analysis of the production data, displaying the analysis results in real time on the monitoring interface, and triggering an alarm when it does not meet the standards;

[0039] S103, detecting the operating status of the wire drawing equipment, performing trend analysis, and determining the fault type of the equipment based on the trend analysis.

[0040] The beneficial effects of the present invention are as follows: the present invention can collect various aspects of operating data of wire drawing equipment in real time, covering the key operating parameters of the equipment, and realizes all-round and no-dead-angle monitoring of the equipment operating status by establishing a communication connection with the equipment control terminal and deploying various sensors at key positions of the equipment, providing an accurate data basis for subsequent analysis and decision-making. By calculating the statistical quantities such as the mean, standard deviation, and rate of change of parameters such as speed, temperature, and vibration, and performing trend analysis on the operating parameters, the present invention can clearly understand the changing trend of the equipment operating status, promptly discover abnormal fluctuations in the operating parameters, and predict in advance possible problems with the equipment, such as unstable motor speed and transmission component failure.

8. A monitoring system for a metal wire drawing device according to claim 6, characterized in that, For the vibration parameter sequence A RMS1 , A RMS2 ,..., A RMSm , calculate the simple moving average of the vibration parameters The specific calculation formula is as follows: Based on the simple moving average of the vibration parameters, calculate the difference of the moving average to determine the trend change of the vibration parameters. The specific calculation formula is as follows: Among them, ΔA RMS (n) represents the change amount of the change trend of the temperature parameter, represents the simple moving average of the vibration parameter at position n - 1. When ΔA RMS (n)>0, it indicates that the vibration amplitude is on the rise. When ΔA RMS (n)<0, it indicates that the vibration amplitude is on the decline. When the speed is on a continuous downward trend and finally drops below v vmin , it indicates that the device is gradually losing power. If the temperature is on a continuous upward trend and exceeds T tmax , it indicates that there is a fault inside the device leading to continuous accumulation. When the vibration amplitude is on a continuous upward trend and exceeds A RMSmax , it indicates that the mechanical components of the device are worn more severely and the connection between components is loose, resulting in abnormal increase in vibration. When the monitored operating parameters exceed the normal range threshold, the system quickly triggers the alarm mechanism and notifies relevant personnel by means of popping up an alarm window, emitting an audible and visual alarm signal, sending text messages or emails, etc.
