Description

Technical Field

[0001] This invention belongs to the field of production equipment monitoring technology, specifically a high temperature early warning and automatic fire prevention device for electrode plates in annealing and pickling lines. Background Technology

[0002] The electrode plate in the annealing and pickling line is a conductive component installed in the electrolysis section of the annealing and pickling production line. It is connected to the power supply system and conducts current to the electrolyte in the pickling tank, thereby creating an electrochemical reaction environment between the steel strip and the electrolyte to enhance the removal of oxide scale and the surface cleaning effect. The electrode plate is usually connected to the power supply system through conductive structures such as copper busbars and cable connectors. During long-term operation, it plays a role in current conduction and assists in electrochemical reaction, and is a key conductive component in the electrolytic pickling device.

[0003] During the operation of the existing annealing and pickling process section, the electrolysis system consists of multiple electrode plates. The temperature rise of each electrode plate varies due to different operating conditions. The existing high-temperature monitoring equipment for the electrode plates in the annealing and pickling line monitors the temperature status of the electrolysis system in real time, but it is difficult to identify and distinguish a single risky electrode plate, thus making it impossible to provide accurate early warning of abnormal temperature rise of the electrode plate. Therefore, this invention proposes a high-temperature early warning and automatic fire prevention device for the electrode plate of the annealing and pickling line. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a high-temperature early warning and automatic fire prevention device for electrode plates in annealing and pickling lines.

[0005] The technical problem to be solved by this invention is: How to implement high-temperature early warning for electrode plate temperature.

[0006] The objective of this invention can be achieved through the following technical solutions: A high-temperature early warning and automatic fire prevention device for electrode plates in an annealing and pickling line includes a data acquisition module, a data processing module, a temperature analysis module, a risk assessment module, an anomaly location module, a level evaluation module, a decision generation module, a visualization module, and a database module. The data acquisition module is used to collect the monitoring temperature data of the electrode plate under test and send it to the data processing module. The database module is used to store the normal operation data of the electrode plate under test and send it to the data processing module and the risk assessment module. The data processing module is used to detect anomalies in the temperature monitoring data of the electrode plate under test, and sends the detected temperature monitoring data of the electrode plate under test to the temperature analysis module, risk assessment module and visualization module; the temperature analysis module is used to analyze the temperature increase and decrease of the electrode plate under test based on the monitoring temperature data, and sends the analyzed temperature rise signal and high temperature anomaly signal to the risk assessment module. The database module is also used to store the electrode plate serial numbers of all the electrode plates to be tested and send them to the risk assessment module and the anomaly location module; the risk assessment module is used to assess whether the electrode plate to be tested has a high temperature risk based on the temperature rise signal and the high temperature anomaly signal, send the temperature danger signal generated by the assessment to the anomaly location module and the decision generation module, send the temperature warning signal to the decision generation module, send the temperature danger signal and the electrode plate temperature of the risky electrode plate to the level assessment module, and send the risky electrode plate serial number of the risky electrode plate to the anomaly location module; The anomaly location module is used to locate and identify risky electrode plates that are in a dangerous state, and send the resulting set of risky electrode plates to the visualization module; the level assessment module is used to assess the hazard level of the risky electrode plates, and send the resulting hazard information to the decision generation module; the decision generation module is used to generate corresponding control commands based on the temperature hazard signal and hazard information; the visualization module is used to visualize and display the electrode plate temperature and the set of risky electrode plates for all the electrode plates to be tested.

[0007] Furthermore, the monitored temperature data are the plate temperatures at all time points corresponding to the upper end of the corresponding electrode plates of all the tested electrode plates.

[0008] Furthermore, the normal operating data refers to the maximum and minimum temperatures of the electrode plate under normal operating conditions.

[0009] Furthermore, the specific working process of the data processing module is as follows: Determine whether there is a corresponding plate temperature at all time points in the normal operation data; If no corresponding electrode temperature exists at any time point, the corresponding time point is recorded as an abnormal time point. The electrode temperature corresponding to the previous time point and the electrode temperature corresponding to the next time point of the abnormal time point are obtained. Then, the interval between adjacent time points is obtained, the electrode correction temperature corresponding to the abnormal time point is calculated, and the electrode temperature corresponding to the abnormal time point is replaced with the electrode correction temperature. If there is a corresponding plate temperature at all time points, the maximum plate temperature is subtracted from the minimum plate temperature to calculate the maximum temperature difference of the plate to be measured. Then, the minimum plate temperature is subtracted from the plate temperature, and the result is divided by the maximum temperature difference to calculate the normalized plate temperature. The normalized plate temperature is then summarized again into the monitoring temperature data of the electrode plate under test.

[0010] Furthermore, the analysis process of the temperature analysis module is as follows: A fixed number of time points are selected, and the time interval formed by the fixed number of time points is recorded as the monitoring time interval. Then, the plate temperature of the electrode at any time point is subtracted from the plate temperature of the previous time point to calculate the plate temperature difference between adjacent time points. Subtract the previous time node from the next time node to calculate the interval between adjacent time nodes. The rate of temperature change of the electrode plate between adjacent time points is calculated by dividing the temperature difference between adjacent time points by the time interval. The number of temperature change rates greater than zero is recorded as the temperature rise number, and the temperature rise ratio of the electrode plate under test is calculated. The average temperature change rate of the electrode plate under test between adjacent time points is calculated by summing all the temperature change rates and taking the average value. When the average temperature change rate is greater than zero and the temperature rise ratio is greater than the preset ratio, the temperature change of the electrode plate under test within the monitoring time interval is determined to be a temperature rise, and a temperature rise signal is generated. When the average temperature change rate is less than or equal to zero, or the temperature rise ratio is less than or equal to the preset ratio, proceed to the next step. If the temperature of any electrode plate under test is 1, the electrode plate under test is determined to be in a high temperature abnormality, and a high temperature abnormality signal is generated; if the temperature of any electrode plate under test is zero, the electrode plate under test is determined to be in a low temperature abnormality.

[0011] Furthermore, the risk assessment module's assessment process is as follows: When a temperature rise signal is generated, the maximum temperature of the electrode plate under normal operating conditions is obtained, and the warning temperature of the electrode plate is calculated by multiplying the maximum temperature of the electrode plate by the temperature warning value. The plate temperature of the electrode plate under test is compared with the warning temperature and the maximum plate temperature. If the plate temperature is less than the warning temperature, no operation is performed. If the plate temperature is less than the maximum plate temperature but greater than or equal to the warning temperature, the corresponding electrode plate under test is determined to be in a warning state, and a temperature warning signal is generated. If the plate temperature is greater than or equal to the maximum plate temperature, the corresponding electrode plate under test is determined to be in a dangerous state, and a temperature danger signal is generated. When a high temperature anomaly signal is generated, the corresponding electrode plate under test is determined to be in a dangerous state, and the corresponding electrode plate under test is recorded as a risk electrode plate. At the same time, the plate temperature and the sequence number of the risk electrode plate are obtained, and a temperature danger signal is generated.

[0012] Furthermore, the location process of the anomaly location module is as follows: Centered on the risk electrode plate number, obtain the electrode plate temperature of adjacent electrode plates; if the electrode plate temperature of an adjacent electrode plate is greater than or equal to the warning temperature, then mark the corresponding adjacent electrode plate as an associated risk electrode plate; if the electrode plate temperature of an adjacent electrode plate is less than the warning temperature, then no operation is performed. The electrode plate numbers of the risk electrode plates and related risk electrode plates are summarized into a risk electrode plate set.

[0013] Furthermore, the evaluation process of the rating assessment module is as follows: When a temperature danger signal is generated, the plate temperature of the risk electrode plate is obtained, and the maximum plate temperature is subtracted from the plate temperature to calculate the temperature over-limit value of the risk electrode plate. If the temperature exceedance value is less than the first danger temperature, the risk electrode plate is determined to be at level three danger, and level three danger information is generated; if the temperature exceedance value is less than the second danger temperature, but greater than or equal to the first danger temperature, the risk electrode plate is determined to be at level two danger, and level two danger information is generated; if the temperature exceedance value is greater than or equal to the second danger temperature, the risk electrode plate is determined to be at level one danger, and level one danger information is generated. The information on the first-level hazard level, the second-level hazard level, and the third-level hazard level is combined and summarized into the hazard information of the risk electrode plate.

[0014] Furthermore, the second danger temperature is greater than the first danger temperature, and the first danger temperature is greater than zero; The level of danger of a Class I hazard is higher than that of a Class II hazard, and the level of danger of a Class II hazard is higher than that of a Class III hazard.

[0015] Furthermore, the decision generation process of the decision generation module is as follows: Upon receiving a temperature warning signal, a level one control command is generated; When a Level 3 hazard level information is received, a Level 2 control command is generated; Upon receiving information indicating a level 2 hazard, a level 3 control command is generated. When a Level 1 hazard information or a temperature hazard signal is received, a Level 4 control command is generated.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses a data processing module to detect anomalies in the temperature data of the electrode plate under test, thereby obtaining the temperature data of the electrode plate under test. Then, a temperature analysis module is used to analyze the temperature increase or decrease of the electrode plate under test based on the temperature data, and to obtain the temperature rise signal and high temperature anomaly signal. 2. This invention utilizes a risk assessment module to determine whether the electrode plate under test poses a high-temperature risk based on temperature rise signals and high-temperature anomaly signals. The assessment generates temperature hazard signals, temperature warning signals, and temperature danger signals, and obtains the electrode plate temperature and sequence number of the risk electrode plate. Then, an anomaly location module is used to locate and identify the risk electrode plate in a dangerous state. At the same time, a level assessment module evaluates the danger level of the risk electrode plate. The danger information of the risk electrode plate is sent to the decision generation module. Finally, the decision generation module generates corresponding control commands based on the temperature hazard signals and danger information to achieve accurate early warning of abnormal temperature rise of the electrode plate in the annealing and pickling line.

[0017] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0018] Figure 1 This is an overall system block diagram of the present invention; Figure 2 This is a front view of the electrode plate in this invention; Figure 3 This is a top view of the electrode plate in this invention; Figure 4 This is a flowchart of the method of the present invention. Detailed Implementation

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1, please refer to Figures 1-3 As shown, the technical solution provided by this invention is: a high-temperature early warning and automatic fire prevention device for electrode plates in annealing and pickling lines. This system analyzes the temperature increase and decrease of the electrode plates under test by monitoring temperature data, and determines whether a single electrode plate under test has a high-temperature risk based on the analyzed temperature rise signal and high-temperature anomaly signal; generates a temperature early warning signal or temperature danger signal based on the determination result, and simultaneously identifies the risky electrode plates; locates and identifies the risky electrode plates in a dangerous state to determine whether the electrode plates under test adjacent to the risky electrode plates are associated risky electrode plates; generates corresponding danger level information based on the temperature exceeding the limit value of the electrode plates. The system includes a data acquisition module, a data processing module, a temperature analysis module, a risk determination module, an anomaly location module, a level assessment module, a decision generation module, a visualization module, and a database module; in this embodiment, the electrode plates in the annealing and pickling line are referred to as the electrode plates under test. The data acquisition module is used to collect the monitoring temperature data of the electrode plate under test and send the monitoring temperature data to the data processing module. Specifically, the monitored temperature data refers to the temperature of the upper part of the electrode plate at all time points for all the electrode plates under test. It should be noted that the electrode plates under test are divided into the upper part, the middle part, and the lower part. The upper part of the electrode plate is the area that is not immersed in the electrolyte. The middle and lower parts of the electrode plate can dissipate heat through the electrolyte, so only the temperature of the upper part of the electrode plate needs to be collected. Furthermore, the database module is used to store the normal operation data of the electrode plate under test, and to send the normal operation data to the data processing module and the risk assessment module; Specifically, the normal operating data refers to the maximum and minimum temperatures of the electrode plate under normal operating conditions. The data processing module is used to detect anomalies in the temperature monitoring data of the electrode plate under test. The detection process is as follows: Step A101: Determine whether there is a corresponding plate temperature at all time points in the normal operation data; If there is no corresponding plate temperature at any time point, the corresponding time point is recorded as an abnormal time point and proceeds to step A102. If a corresponding plate temperature exists at all time points, proceed to step A103; Step A102: Obtain the plate temperature T corresponding to the time point preceding the abnormal time point. k-1 and the corresponding plate temperature T at the next time node k+1 Where k is the time node number, and the time interval S between adjacent time nodes is obtained, the plate correction temperature T corresponding to the abnormal time node is calculated by the formula. k The corresponding plate temperature at abnormal time points is replaced with the plate correction temperature, and the specific formula is as follows: T k =T k-1 +(T) k+1 -T k-1 ) / 2; If the abnormal time node is the first time node in the monitored temperature data, then the plate temperature corresponding to the next time node after the abnormal time node is taken as the plate temperature corresponding to the previous time node; if the abnormal time node is the last time node in the monitored temperature data, then the plate temperature corresponding to the previous time node is taken as the plate temperature corresponding to the next time node. Step A103: Subtract the minimum temperature of the electrode from the maximum temperature of the electrode to calculate the maximum temperature difference of the electrode plate to be tested. Then, subtract the minimum temperature of the electrode from the electrode temperature and divide the calculation result by the maximum temperature difference to calculate the normalized electrode temperature. It should be noted that if the plate temperature is greater than or equal to the maximum plate temperature, the normalized plate temperature is recorded as one; if the plate temperature is less than or equal to the minimum plate temperature, the normalized plate temperature is recorded as zero. Normalization is used to eliminate the problem of inconsistent temperature dimensions and make subsequent temperature analyses comparable. Step A104: The normalized plate temperature is summarized again into the monitoring temperature data of the plate under test. The data processing module sends the monitored temperature data of the electrode plate under test to the temperature analysis module, risk assessment module, and visualization module.

[0021] Specifically, the temperature analysis module is used to analyze the temperature increase or decrease of the electrode plate under test based on the monitored temperature data. The analysis process is as follows: Step B101: Select a fixed number of time nodes and record the time interval formed by the fixed number of time nodes as the monitoring time interval. Then, subtract the electrode temperature of the previous time node from the electrode temperature of any time node to calculate the electrode temperature difference between adjacent time nodes. If there is no previous time point at any given time point, the temperature difference of the corresponding plate is recorded as zero. Step B102: Subtract the previous time node from the next time node to calculate the interval between adjacent time nodes. Step B103: Divide the temperature difference between adjacent time points by the time interval to obtain the rate of temperature change of the electrode plate under test between adjacent time points. Step B104: Record the number of temperature change rates greater than zero as the temperature rise rate, and calculate the temperature rise ratio of the electrode plate under test using the following formula: Temperature rise ratio = Temperature rise rate / (fixed quantity - 1); Step B105: Sum all the temperature change rates and take the average value to calculate the average temperature change rate of the electrode plate under test between adjacent time points. When the average temperature change rate is greater than zero and the temperature rise ratio is greater than the preset ratio, the temperature change of the electrode plate under test within the monitoring time interval is determined to be a temperature rise, and a temperature rise signal is generated. When the average temperature change rate is less than or equal to zero, or the temperature rise ratio is less than or equal to a preset ratio, proceed to step B106. The preset ratio can be configured through system parameters. In this embodiment, the preset ratio is set to 0.6. Step B106: If the temperature of any electrode plate under test is one, the electrode plate under test is determined to be in high temperature abnormality, and a high temperature abnormality signal is generated. If the temperature of any of the test electrode plates is zero, the test electrode plate is determined to be in a low-temperature abnormality. The temperature analysis module sends the temperature rise signal and high temperature anomaly signal to the risk assessment module.

[0022] As a further embodiment, the database module is also used to store the electrode plate serial numbers of all the electrode plates to be tested, and send the electrode plate serial numbers to the risk assessment module and the anomaly location module. Specifically, the risk assessment module is used to assess whether there is a high-temperature risk on the electrode plate under test based on the temperature rise signal and the high-temperature anomaly signal. The assessment process is as follows: Step C101: When a temperature rise signal is generated, the maximum temperature of the electrode plate under normal operating conditions is obtained, and the maximum temperature of the electrode plate is multiplied by the temperature warning value to calculate the warning temperature of the electrode plate under test. The temperature warning value is preset by technicians based on historical operating data and the properties of the electrode plate material; in practice, the temperature warning value can range from 0.7; the temperature warning coefficient is greater than zero; in practice, the temperature warning coefficient can be 0.7. Step C102: Compare the plate temperature of the electrode plate to be tested with the warning temperature and the maximum plate temperature. If the plate temperature is lower than the warning temperature, no operation will be performed; If the plate temperature is lower than the maximum plate temperature but greater than or equal to the warning temperature, the corresponding plate under test is determined to be in a warning state, and a temperature warning signal is generated. If the temperature of the electrode plate is greater than or equal to the maximum temperature of the electrode plate, the corresponding electrode plate under test is determined to be in a dangerous state, and a temperature danger signal is generated. Step C103: When a high temperature abnormality signal is generated, the corresponding electrode plate to be tested is determined to be in a dangerous state, and the corresponding electrode plate to be tested is recorded as a risk electrode plate. At the same time, the plate temperature and the sequence number of the risk electrode plate are obtained, and a temperature danger signal is generated. The risk determination module sends the temperature hazard signal to the anomaly location module and the decision generation module, sends the temperature warning signal to the decision generation module, sends the temperature hazard signal and the electrode plate temperature of the risk electrode plate to the level assessment module, and sends the risk electrode plate serial number of the risk electrode plate to the anomaly location module.

[0023] Specifically, the anomaly location module is used to locate and identify risk electrode plates that are in a dangerous state. The location process is as follows: Step D101: Using the risk electrode plate number as the center, obtain the plate temperature of the adjacent electrode plates. If the temperature of an adjacent electrode plate is greater than or equal to the warning temperature, the corresponding adjacent electrode plate will be marked as an associated risk electrode plate. If the temperature of the adjacent electrode plates is lower than the warning temperature, no operation will be performed. Step D102: Summarize the electrode plate numbers of the risk electrode plates and associated risk electrode plates into a risk electrode plate set; The anomaly location module sends the risk electrode set to the visualization module.

[0024] Specifically, the hazard assessment module is used to assess the hazard level of the risk electrode plate, and the assessment process is as follows: Step E101: When a temperature danger signal is generated, the plate temperature of the risk electrode plate is obtained, and the maximum plate temperature is subtracted from the plate temperature to calculate the temperature over-limit value of the risk electrode plate. Step E102: If the temperature exceedance value is less than the first danger temperature, the risk electrode plate is determined to be at level three danger, and level three danger information is generated. If the temperature exceedance value is less than the second danger temperature but greater than or equal to the first danger temperature, the risk electrode plate is determined to be at the second danger level, and second danger level information is generated. If the temperature exceeds the limit by more than or equal to the second danger temperature, the risk electrode plate is determined to be at the first danger level, and first danger level information is generated. Among them, the second danger temperature is greater than the first danger temperature, and the first danger temperature is greater than zero; the danger level of the first-level danger level is higher than that of the second-level danger level, and the danger level of the second-level danger level is higher than that of the third-level danger level. Step E103: Combine and summarize the Level 1, Level 2, and Level 3 hazard information into the hazard information of the risk electrode plate; The risk assessment module sends the hazard information of the risk electrode plate to the decision generation module.

[0025] The decision generation module is used to generate corresponding control commands based on temperature hazard signals and hazard information. The decision generation process is as follows: Step F101: When a temperature warning signal is received, a first-level control command is generated; Specifically, the first-level control commands include increasing the electrolyte circulation flow rate in the pickling tank, reducing the input current of the risk electrode plate, and sending early warning information to on-site operators; Step F102: When a Level 3 hazard level information is received, a Level 2 control command is generated; In practice, the secondary control commands include cutting off the power supply to the corresponding risk electrode plate and simultaneously activating the local cooler in the tank. Step F103: When a Level 2 hazard information is received, a Level 3 control command is generated; The Level 3 control commands include cutting off the power supply to all the electrode plates under test, starting the whole-slot cooling system, turning on the exhaust ventilation, and sending a pre-fire notification to the fire control center. Step F104: When a Level 1 hazard information or a temperature hazard signal is received, a Level 4 control command is generated. Furthermore, the Level 4 control commands include activating automatic fire extinguishers, cutting off the main power supply to the annealing and pickling line, activating the emergency smoke exhaust system, sending an automatic alarm signal to the fire control center, and triggering audible and visual alarms.

[0026] Specifically, the visualization module is used to visualize the temperature of all the electrode plates under test and the set of risk electrode plates; The visualization module consists of a WinCC device and a touch screen. It displays the plate temperature of all the electrode plates under test, the corresponding position of the risk electrode plate, and the corresponding position of the associated risk electrode plate adjacent to the risk electrode plate. It can highlight the electrode plate number of the risk electrode plate and the associated risk electrode plate to show the corresponding position of the risk electrode plate and the corresponding position of the associated risk electrode plate adjacent to the risk electrode plate.

[0027] Example 2, please refer to Figure 4 As shown, based on another concept of the same invention, a method for high-temperature early warning and automatic fire prevention of electrode plates in annealing and pickling lines is proposed, including the following steps: Step S100: Obtain the monitoring temperature data of the electrode plate under test, and determine the temperature increase or decrease of the electrode plate under test based on the monitoring temperature data to obtain the temperature rise signal and the high temperature abnormal signal. Step S200: Based on the temperature rise signal and the high temperature anomaly signal, a risk assessment is performed on the electrode plate under test to determine whether there is a high temperature risk, and the electrode plate under test that is not in a dangerous state and the risk electrode plate that is in a dangerous state are determined. Step S300: Locate and identify the associated risk electrode plates and the risk electrode plates that are in a dangerous state, and summarize the electrode plate serial numbers of the associated risk electrode plates and the risk electrode plates into a risk electrode plate set. Step S400: The hazard level of the risk electrode plate is assessed by the plate temperature of the risk electrode plate, the hazard information of the risk electrode plate is obtained by assessment, and corresponding control commands are generated at the same time. Step S500: Visualize the temperature of all the electrode plates to be tested and the set of risk electrode plates.

If the temperature exceedance value is less than the first danger temperature, the risk electrode plate is determined to be at level three danger, and level three danger information is generated; if the temperature exceedance value is less than the second danger temperature, but greater than or equal to the first danger temperature, the risk electrode plate is determined to be at level two danger, and level two danger information is generated. If the temperature exceeds the limit by more than or equal to the second danger temperature, the risk electrode plate is determined to be at the first danger level, and first danger level information is generated. The information on the first-level hazard level, the second-level hazard level, and the third-level hazard level is combined and summarized into the hazard information of the risk electrode plate.
