Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0043] The technical solution provided by the embodiments of the present invention is described in detail below with reference to the accompanying drawings.

[0046] Therefore, the management system for the whole life cycle of the straightener of the present invention collects the operating data of the straightener, determines the operating status of the straightener, and issues an early warning for the faulty parts of the straightener. Therefore, the straightener can be repaired or suspended in time, and damage to the straightener during operation can be avoided, thereby reducing the maintenance and replacement costs of the straightener. By evaluating the health of the straightener, on the one hand, the operating accuracy of the straightener is guaranteed, while the use efficiency of the straightener is guaranteed, and the problem of multiple repairs of the straightener due to health problems affecting the work quality and work efficiency is avoided. On the other hand, through the detection of the health status, the straightener can be kept in a healthy working state, thereby ensuring the service time of the straightener and the service life of the straightener, which indirectly achieves the purpose of cost saving. Through the comprehensive management of the management module 3 and the control and visual display of the control module 4, the operating status and use status of the straightener are clearly and intuitively reflected. At the same time, due to real-time detection and data storage, the management of the whole life cycle of the straightener can be realized.

[0047] Specifically, in the full life cycle management system for a straightening machine of the present invention, the equipment operation monitoring module 1 includes: a data acquisition module 11, a data processing module 12 and an early warning module 13, wherein:

[0048] The data acquisition module 11 is used to collect the operating data of the straightening machine; the data processing module 12 is used to clean the data collected by the data acquisition module 11, classify and store the cleaned data, and filter out invalid data for deletion; the early warning module 13 is used to judge the working status of the straightening machine according to the data processed by the data processing module 12, and issue early warnings to the parts with operating faults according to the judgment results.

[0049] It should be noted that the above-mentioned data cleaning includes deleting the data repeatedly collected by the data acquisition module 11, correcting the data with incorrect format and data with incorrect arrangement, so that the acquired data has a unified format and a fixed order, which is used for the early warning module 13 to perform early warning or the management module 3 to perform comprehensive management.

[0050] As an example, the above-mentioned data storage in the present invention includes saving as independent files according to data source and time. A data cache mechanism can be added during the data storage process to improve data collection efficiency; the screened invalid data includes data stored for half a year, and the historical files are cleaned up using the first-in-first-out rule.

[0051] Therefore, through data collection and data cleaning in the equipment operation monitoring module 1, the acquired data are the straightening roller operation and status parameters with consistent format, orderly arrangement and no repeated data.

[0052] In some optional implementations of this embodiment, the control module 4 may be selected as a PLC control system or a host computer. The visual display methods in the control module 4 include radar chart style, star chart and table style. For example, when the radar chart style is used to display the health of each dimension of the straightener, each dimension may correspond to an axis on the radar chart, and the score of the dimension may be represented by the distance from the center to the edge, so that the performance or status of multiple dimensions can be intuitively displayed; at the same time, in order to facilitate the detection and management of other uncommon straightener types or models throughout the life cycle, and to improve the compatibility and scope of use of the full life cycle management system of the present invention, it also supports the import and export of data and supports multiple compatible formats.

[0053] In some optional implementations of this embodiment, the data collected by the data collection module 11 includes main transmission data, hydraulic system data, equipment body data and auxiliary equipment data, wherein:

[0054] The main transmission data includes: main motor operating data and reducer operating data, among which the main motor operating data includes bearing temperature, winding temperature, motor current, speed and motor vibration data, etc.; when obtaining the reducer operating data, if there is a gear box, the temperature and vibration on the input / output side of each shaft are monitored and obtained.

[0055] The hydraulic system data include: servo valve parameters, which mainly monitor whether the servo valve has zero drift, internal leakage, jamming and other faults and issue early warnings in time; hydraulic oil quantity data, which mainly monitors whether the hydraulic oil is leaking. By monitoring the oil temperature, oil level and oil quality parameters in the target hydraulic system, the existing hydraulic system status monitoring model is used to calculate the change in the system hydraulic oil, identify abnormal oil quantity and issue hydraulic system oil leakage early warning; fuel consumption data, which mainly identifies the equipment movement during the refueling process, automatically counts the refueling flow data of the hydraulic station, and obtains the fuel consumption of the hydraulic station in the statistical period, and can compare the fuel consumption of different periods, compare the fuel consumption of different periods and count the number of refuelings, and transmit the abnormal fuel consumption of the straightening machine to the early warning module 13 for early warning.

[0056] The equipment body data includes: reducer lubrication status data and dry oil consumption data, among which the reducer lubrication status data includes continuous monitoring and acquisition of the reducer oil level, and recording the oil level, and timely pushing and alarming when the oil level is abnormal; the dry oil consumption data includes statistically analyzing the refueling flow data of the lubrication station to obtain the oil consumption of the lubrication station in the statistical period, and can compare the oil consumption of different periods, display the oil consumption of different periods, and transmit the abnormal fluctuation data of the oil consumption to the early warning module 13 for alarm; the roller motor status data includes monitoring the changes in the current of each roller motor, judging the operating status of the roller motor under different working conditions by the current change trend, and transmitting the abnormal data to the early warning module 13 for alarm, so as to reduce or avoid batch quality accidents caused by problems such as single roller locking.

[0057] Auxiliary equipment data include: equipment used to perform closed-loop detection on main transmission data, hydraulic system data and equipment body data to ensure the accuracy of the operating data of the above equipment, thereby ensuring that the straightening machine operates in a safe and efficient state.

[0058] In some optional implementations of this embodiment, the above-mentioned data collection can be performed by performing real-time concurrent data collection through the S7 protocol; such as accessing and writing network programming code, listening to designated ports, receiving and parsing data packets, and the collected data sources may include control end data, monitoring systems, separate measurement systems, etc.; at the same time, in order to ensure the continuity of data collection, an automatic reconnection mechanism is added during the data collection process, and when a disconnection is detected, an attempt is automatically made to re-establish the connection; in order to ensure the integrity and accuracy of the data, a data verification mechanism is added during the data transmission process, and the collection frequency can also be controlled to be less than or equal to 500ms during the collection process.

[0059] Exemplarily, in order to realize the above data collection, and at the same time make the structure simple and easy to operate during the data collection process, ensure the collection accuracy, reduce the cost of data collection, and at the same time not affect the normal operation of the straightener during the data collection process, the data collection module 11 may include a plurality of sensors, and the plurality of sensors are arranged at different working parts of the straightener, respectively used to detect the working state of different working parts of the straightener, obtain the operation data of the straightener, and transmit the obtained data. In combination with practical applications, the above-mentioned multiple sensors may at least include: encoders, pressure sensors, temperature sensors, displacement sensors, thermal detectors, pyrometers, level meters, flow meters, etc. according to different functions and usage conditions.

[0060] In some optional implementations of this embodiment, in addition to the data acquisition of the above-mentioned sensors, data detection can also be performed. By continuously monitoring the parameters of various sensors, problems such as sensor jumps and flashes can be discovered and warned, thereby better ensuring the accuracy of multiple detection data and further ensuring the accuracy of the straightening machine's full life cycle management.

[0061] Specifically, in the full life cycle management system for the straightener of the present invention, the health assessed by the health assessment module 2 includes the health of the mechanical part of the straightener, the health of the electrical part, the health of the hydraulic system and the health of the safety protection device, wherein:

[0062] The health of the mechanical part includes the health of the equipment structure integrity, the health of the transmission system, the health of the straightening rollers and the health of the guide device; the health of the equipment structure integrity is determined by regularly checking whether there are cracks, deformations and other problems in the equipment structure; the health of the transmission system is determined by monitoring the vibration and temperature values ​​output by the vibration sensor and temperature sensor of the transmission chain; the health of the straightening roller is determined by detecting the wear condition by the detection sensor and monitoring the temperature and hardness changes of the roller surface; the health of the guide device is determined by monitoring the displacement and deformation of the guide device by the displacement sensor.

[0063] The health of the electrical part includes the health of the motor used to drive the straightening roller of the straightening machine, the health of the control system, the health of the sensor and the health of the electrical circuit; among which:

[0064] The motor health is determined by monitoring the motor's operating status through current, voltage and temperature sensors, and by using vibration sensors to detect the vibration of the motor bearings. The control system health is evaluated by monitoring the controller's input and output signals, operating time and error codes to assess the stability and reliability of the control system. The sensor health is evaluated by comparing the difference between the sensor output value and the expected value or reference value to assess the accuracy and reliability of the sensor. The electrical line health is monitored by using a temperature sensor to monitor the line temperature, and an insulation resistance tester is used to detect the insulation performance of the line. In addition, the health of the equipment energy consumption can also be tested, including: the power transmission circuit collects and analyzes the energy consumption of the same load, and the increase in equipment energy consumption is measured. Less than 5% is evaluated as normal, greater than or equal to 5% and less than 10% is evaluated as abnormal, and greater than or equal to 10% is evaluated as energy consumption failure.

[0065] The health of the hydraulic system includes the health of the oil pump, the health of the hydraulic cylinder, the health of the hydraulic pipeline and the health of the hydraulic oil; among which:

[0066] The health of the oil pump is determined by monitoring the output pressure and flow of the oil pump through pressure sensors and flow sensors, and by monitoring the temperature of the oil pump using temperature sensors; the health of the hydraulic cylinder is determined by monitoring the piston position of the hydraulic cylinder through displacement sensors, and by monitoring the working pressure of the hydraulic cylinder; the health of the hydraulic pipeline is determined by monitoring the pressure and temperature of the hydraulic pipeline using pressure sensors and temperature sensors, and by detecting pipeline leakage using leakage detectors; the health of the hydraulic oil is determined by detecting the cleanliness, viscosity and moisture content of the hydraulic oil using an oil quality analyzer.

[0067] In addition, in order to make a comprehensive inspection of the straightening machine, the health of the safety protection devices on the straightening machine can also be inspected, including the health of the emergency stop device, the health of the protective device and the health of the alarm device, among which:

[0068] The health of the emergency stop device is determined by detecting whether the device is in an activated state and the connectivity of the circuit; the health of the protective device is determined by using a displacement sensor to monitor the position and status of the protective device to ensure that it is always in normal working condition; the health of the alarm device is determined by using professional electrical testers and other equipment to check the power supply system, control system, etc. of the alarm device to ensure that all parameters are normal.

[0069] At the same time, in order to further realize the management of the whole life cycle of the straightening machine, the maintenance of the straightening machine can also be tested, including: maintenance record integrity record and maintenance cycle execution status, among which the maintenance record integrity record is recorded and maintained through the information management system to ensure the integrity and accuracy of the record; the maintenance cycle execution status includes the detection of the execution of the maintenance cycle.

[0070] As a feasible implementation method in this embodiment, in order to improve the detection and early warning of the straightener and facilitate the judgment of the health of the straightener, the health level data of different straighteners stored in the health evaluation module can be divided into three levels of high, medium and low according to the level of health. The evaluated health results are compared with the pre-stored health data to determine the health level. For high health, it means that the straightener is in good operating condition, reliable quality, high operating efficiency, accurate straightening, and no changes are made to the straightener and its auxiliary equipment; for medium health, real-time detection is performed. When the detected value or the health monitored at the next moment is lower than that at the previous moment, the straightener is given an early warning maintenance. For the straightener with low health, the operation is stopped for comprehensive maintenance, so as to ensure the straightening accuracy of the straightener and the service life of the straightener, avoid irreversible damage to the straightener and its auxiliary equipment, thereby saving costs, reducing the accident rate, ensuring the safety of operators, and avoiding unnecessary property losses.

[0071] At the same time, in order to further ensure the straightening accuracy and service life of the straightener, the straightener with medium health can be divided into levels one, two and three. Level one is close to high health, which will not affect the straightener and auxiliary equipment, and will not affect its service life and straightening accuracy. Only detection is required. For the straightener with medium health level three, its health tends to be low health, so it is focused on monitoring and maintenance work; for the straightener with medium health level two, its health is between level one and level three of medium health, and real-time detection is carried out. When level two becomes level one, no processing is done. When level two becomes level three within the preset time, the operation is stopped. When level two maintains the original level within the preset time, continuous detection is carried out, or when level two reaches level three for more than the preset time and maintains it, maintenance work is also carried out.

[0072] Second, as Figure 2 As shown, the present invention also provides a method for managing the whole life cycle of a straightening machine, which is implemented by using the above-mentioned management system for the whole life cycle of a straightening machine, and includes:

[0073] Obtain the operating data of the straightener, determine the operating status of the straightener based on the obtained operating data, and issue early warnings for parts with operating faults; compare the obtained straightener operating data with the preset straightener health data to determine the health of the straightener; use a comprehensive evaluation model to conduct a comprehensive evaluation of the straightener based on the early warning information and health; conduct comprehensive management of the straightener based on the comprehensive evaluation results, and visualize the results of the comprehensive evaluation and the results of the comprehensive management.

[0074] Specifically, the above comprehensive evaluation model includes:

[0075] Score=(Jsω1+Dsω2+Ysω3+Asω4+Wsω5)×10;

[0076] Among them: Score represents the comprehensive evaluation result of the straightener, Js represents the health of the mechanical part of the straightener, Ds represents the health of the electrical part of the straightener, Ys represents the health of the hydraulic system of the straightener, As represents the health of the safety protection device of the straightener, Ws represents the maintenance health, ω1 represents the weight ratio of the health of the mechanical part of the straightener, ω2 represents the weight ratio of the health of the electrical part of the straightener, ω3 represents the weight ratio of the health of the hydraulic system of the straightener, ω4 represents the weight ratio of the health of the safety protection device of the straightener, and ω5 represents the weight ratio of the maintenance health.

[0077] Specifically, the health of the mechanical part, the health of the electrical part, the health of the hydraulic system and the health of the safety protection device of the straightening machine are calculated using the following formulas:

[0078]

[0079] Among them: J1 represents the structural integrity health of the straightening machine equipment, J2 represents the health of the straightening machine transmission system, J3 represents the health of the straightening roller, J4 represents the health of the straightening machine guide device, ε1-ε4 respectively represent the weight ratios of the above J1-J4, D1 represents the motor health, D2 represents the control system health, D3 represents the sensor health, D4 represents the electrical circuit health, α1-α4 respectively represent the weight ratios of the above D1-D4, Y1 represents the oil pump health, Y2 represents the hydraulic Cylinder health, Y3 represents the health of the hydraulic pipeline, Y4 represents the health of the hydraulic oil, β1-β4 respectively represent the weight ratios of the above Y1-Y4, A1 represents the health of the emergency stop device, A2 represents the health of the protection device, A3 represents the health of the alarm device, δ1-δ3 respectively represent the weight ratios of the above A1-A3, W1 represents the actual maintenance ratio of the straightener, W2 represents the execution ratio of the maintenance cycle of the straightener, θ1 and θ2 respectively correspond to the weight ratios of the above W1 and W2.

[0080] Taking the health of the mechanical part of the straightening machine as an example, the weight ratios ε1-ε4 of J1-J4 can be selected as 0.2, 0.25, 0.3 and 0.25 in actual application. For the above weight ratios ω1-ω5, 0.25, 0.2, 0.15 and 0.15 can be selected in actual application. All other weight ratios mentioned above are selected according to relevant industry manuals or prior knowledge.

[0081] Therefore, the above-mentioned method for the whole life cycle management of the straightener of the present invention determines the health of the straightener by obtaining the operating parameters of the straightener, comprehensively evaluates the health of each system and each equipment of the straightener through a comprehensive evaluation model, and performs whole life cycle detection and management of the straightener based on the evaluation results.
