[0002] In the early stage of the development of chemical production control models, traditional control theories such as PID control were mainly adopted. Specifically, process parameters were measured, compared with set values, and then control variables were adjusted. For example, in some simple chemical production processes, the flow rate of fluids was controlled by adjusting the opening degree of valves to achieve the expected production effect. With the high requirements for the control fineness of chemical production processes, it is necessary to simulate various phenomena in the production process based on physical and chemical principles such as material balance and energy balance to achieve the effect of chemical production control. However, the existing chemical production control technologies fail to measure the production index offset amounts in multiple stages such as synthesis, purification, and drying of chemical product production, and it is difficult to detect abnormal operation conditions of chemical production equipment based on the production index offset amounts, resulting in insufficient accuracy of chemical production control and low production efficiency of chemical products.

[0079] The present invention collects the original data of the production process of chemical products during the chemical production process, preprocesses the data, and obtains standard chemical production data, which can ensure that the data for subsequent analysis and processing has a unified format and quality, provides a reliable data basis for the precise control of chemical production, and avoids production control errors caused by non-standard and inaccurate data. The standard chemical production data is divided into production stages to obtain chemical production stage data, and then the chemical reaction condition indicators are determined and production index deviation detection is carried out to obtain production index deviation data. This process realizes the refined management and monitoring of each stage of chemical production, can timely detect the slight changes in chemical reaction conditions during the production process, provides a basis for subsequent targeted optimization control, and improves the quality and production efficiency of chemical products. The operating parameters of production equipment are extracted from the standard chemical production data to obtain production equipment operation data, the equipment operation status data is generated by mapping according to the production index deviation data, and equipment abnormal operation detection is carried out to obtain equipment abnormal operation data. This makes the operating status of production equipment closely related to production indicators, can accurately locate the impact of equipment abnormalities on production index deviations, facilitates taking measures in advance to prevent equipment failures, ensures the stable operation of production equipment, and reduces production interruptions and defective products caused by equipment problems. According to the production index deviation data, production deviation optimization control is carried out on the chemical production process products to obtain production deviation optimization measures. At the same time, production equipment operation response control is carried out on the equipment abnormal operation data to obtain equipment abnormal operation response measures, and a chemical production control model is generated based on the two. This model comprehensively considers production indicators and equipment operation status, realizes the closed-loop control of chemical production, can adjust process parameters and equipment operation strategies in real time during the production process, keeps the chemical production process in the optimal state all the time, and effectively improves the overall efficiency and safety of chemical production. Therefore, the present invention realizes the detection of production index deviation amounts in each stage of chemical product production through data analysis technology, pattern recognition technology, and automation control technology, and identifies abnormalities in the operation of chemical production equipment based on the production index deviation amounts, thereby improving the accuracy of chemical production control and the production efficiency of chemical products.
[0080] In an embodiment of the present invention, as shown in Figure 1 The method for generating the chemical production control model includes the following steps:
[0081] Step S1: Obtain chemical products during the chemical production process; collect the original data of the production process of chemical products during the chemical production process to obtain chemical production original data; preprocess the chemical production original data to obtain standard chemical production data;
[0082] In the embodiments of the present invention, various sensors deployed at the chemical production site, such as temperature sensors, pressure sensors, flow sensors, etc., are used to obtain the relevant data of the products in different production links during the chemical production process in real time. These sensors convert the collected signals into electrical signals, and then through a data acquisition card or data acquisition module, at a certain sampling frequency, such as 10 times per second, the electrical signals are converted into digital signals, so as to obtain the original production process data of the products in the chemical production process, including data of parameters such as product density, product content, moisture content, acidity, feed flow rate, discharge flow rate, feed pressure, discharge pressure, feed temperature, discharge temperature, reaction temperature, purity, reaction rate, pH value, liquid level, material concentration, etc. Then, the collected original chemical production data is transmitted to a data processing server or a computer system, and data preprocessing software or a data processing library in a programming language, such as the Pandas library of Python, is used to clean the data. Specifically, missing values are identified and processed. For the missing data, methods such as linear interpolation or mean filling can be used to supplement it according to the data at adjacent time points; outliers are screened and removed. By calculating the statistical quantities of the data, such as the average value, standard deviation, etc., a reasonable threshold is set, and the data outside the threshold range is determined as an outlier and deleted; for the product content data, if its average value is 80% and the standard deviation is 2%, then the data with a content lower than 76% or higher than 84% can be regarded as outliers and removed. Then, the cleaned data is standardized. Using the Z-score standardization method, each data point is subtracted by the average value of the data set and then divided by the standard deviation, so that the processed data conforms to a normal distribution with a mean of 0 and a standard deviation of 1.
[0083] Step S2: Divide the standardized chemical production data into production stages to obtain chemical production stage data; determine the chemical reaction condition indicators for the chemical production stage data to generate chemical reaction condition indicators; detect the production index deviation for the chemical reaction condition indicators to obtain production index deviation data;
[0084] In the embodiments of the present invention, the clustering algorithm in data mining technology is used to divide the standard chemical production data into production stages. The specific operation is as follows: The data of parameters such as product density, product content, moisture content, acidity, feed flow rate, discharge flow rate, feed pressure, discharge pressure, feed temperature, discharge temperature, reaction temperature, purity, reaction rate, pH value, liquid level, and material concentration in the standard chemical production data are used as input features. An appropriate number of clustering centers is selected, for example, set to 3. By calculating the distance between each data point and the clustering center, the data points are divided into the production stages represented by the nearest clustering center, thereby obtaining the chemical production stage data. Then, for each chemical production stage data, a statistical analysis method is used to determine the chemical reaction condition indicators. Taking the reaction temperature as an example, statistical quantities such as the average value, maximum value, minimum value, and standard deviation of the reaction temperature data within each production stage are calculated, and these statistical quantities are used as the chemical reaction condition indicators for this stage, generating a chemical reaction condition indicator data set, which contains the chemical reaction condition indicators corresponding to each production stage. Then, production index offset detection is performed on the chemical reaction condition indicator data set. The normal range threshold of each chemical reaction condition indicator is set. For example, the normal range of the reaction temperature is 80°C - 120°C. By comparing the actual chemical reaction condition indicator with the normal range threshold, if the actual indicator exceeds the normal range, the offset value of the indicator is recorded, that is, the difference between the actual value and the normal range threshold, thereby obtaining the production index offset data.
[0085] Step S3: Extract the production equipment operation parameters from the standard chemical production data to obtain the production equipment operation data; map the production equipment operation data according to the production index offset data to generate the equipment operation status data; perform equipment abnormal operation detection on the equipment operation status data to obtain the equipment abnormal operation data;
[0086] In the embodiments of the present invention, production equipment operation parameters are extracted from standardized chemical production data by using data extraction technology. The specific operation is to screen out the operation parameters directly related to the production equipment, such as the vibration frequency of the equipment, the motor current, and the equipment operation duration, from the standardized chemical production data containing parameters such as product density, product content, moisture content, acidity, feed flow rate, discharge flow rate, feed pressure, discharge pressure, feed temperature, discharge temperature, reaction temperature, purity, reaction rate, pH value, liquid level, and material concentration, so as to obtain the production equipment operation data. Then, the equipment operation state mapping is performed on the production equipment operation data according to the production index offset data. The specific operation is to perform correlation analysis on the offset value in the production index offset data and the corresponding parameters in the production equipment operation data. By setting mapping rules, such as when the production index offset value exceeds a certain threshold, the corresponding parameters in the production equipment operation data are marked as abnormal states. For example, if the production index offset value of the reaction temperature exceeds 5°C, the vibration frequency parameter in the production equipment operation data related to the reaction temperature is marked as an abnormal state, which includes information such as equipment ID, parameter name, parameter value, and operation state. The equipment abnormal operation detection is performed on the equipment operation state data. Specifically, machine learning algorithms, such as support vector machines, are used to perform classification analysis on the equipment operation state data. The normal state data in the equipment operation state data is used as the training set, and the abnormal state data is used as the test set to train the machine learning model. The abnormal conditions in the equipment operation state data are predicted through the model. If the model prediction result is abnormal, the data is recorded as equipment abnormal operation data, which includes information such as equipment ID, abnormal parameter name, abnormal parameter value, and abnormal time. The SVM algorithm in the Scikit-learn library of Python is used to train and predict the equipment operation state data to obtain the equipment abnormal operation data.
[0087] Step S4: Perform production offset optimization control on the chemical production process products according to the production index offset data to obtain production offset optimization measures; perform production equipment operation response control on the equipment abnormal operation data to obtain equipment abnormal operation response measures; generate a chemical production control model based on the production offset optimization measures and the equipment abnormal operation response measures to obtain a chemical production control model.
[0088] In the embodiments of the present invention, production offset optimization control is performed on chemical production process products according to production index offset data. The specific operation is to use an association rule mining algorithm, such as the Apriori algorithm, to analyze the production index offset data, calculate the support and confidence between various indicators, and thus generate production offset optimization rules. For example, setting the minimum support to 0.5 and the minimum confidence to 0.6, it is found through calculation that when the reaction temperature offset value exceeds 5°C and the feed flow rate offset value exceeds 10%, adjusting the stirring speed of the reaction kettle can improve the product purity, and corresponding production offset optimization measures are generated, including information such as the parameter name to be adjusted, the adjustment range, and the adjustment time. Then, production equipment operation response control is performed on the equipment abnormal operation data. Specifically, the decision tree algorithm in the machine learning algorithm is used to classify and analyze the equipment abnormal operation data, and according to information such as the equipment ID, abnormal parameter name, abnormal parameter value, and abnormal time in the equipment abnormal operation data, equipment abnormal operation response rules are generated. For example, when the equipment vibration frequency is abnormal and the motor current is abnormal, the equipment operation is immediately stopped and repaired, and equipment abnormal operation response measures are generated, including information such as the response equipment ID, response measure description, and response time. Then, a chemical production control model is generated based on the production offset optimization measures and the equipment abnormal operation response measures. Specifically, the production offset optimization measures and the equipment abnormal operation response measures are integrated into a control strategy table, which contains various parameters in the production process, the corresponding optimization measures or response measures, and the trigger conditions. Through the automated control system, various parameters in the production process are monitored in real time. When the parameters reach the trigger conditions, the corresponding optimization measures or response measures are automatically executed, thereby realizing the automatic control of the chemical production process and obtaining a chemical production control model.

[0092] Step S23: Identify the chemical production stage state of the chemical production stage data to obtain chemical production stage state data; detect the chemical reaction conditions of the chemical products for the chemical production stage state data to generate stage chemical reaction data;
[0093] Step S24: Judge the production stage reaction condition indexes for the stage chemical reaction data to generate chemical reaction condition indexes; determine the production stage chemical reaction index benchmarks according to the chemical reaction condition indexes to obtain the stage chemical reaction index benchmarks;
[0094] Step S25: Detect the anomalies of the stage chemical reaction indexes for the stage chemical reaction data to obtain reaction index anomaly data; measure the production index offset for the reaction index anomaly data according to the stage chemical reaction index benchmarks to obtain production index offset data.
[0095] In the embodiments of the present invention, data processing technology is used to extract production stage timestamps from standardized chemical production data. The specific operation is to screen out time-related fields, such as "production start time", "production end time", etc., from the standardized chemical production data containing parameters such as product density, product content, moisture content, acidity, feed flow rate, discharge flow rate, feed pressure, discharge pressure, feed temperature, discharge temperature, reaction temperature, purity, reaction rate, pH value, liquid level, material concentration, etc. through a data processing script or a database query statement. Then, the standardized chemical production data is marked with production stages according to the production stage timestamps to generate production stage identification data, which includes the start time, end time, and corresponding production data of each production stage. The production stage identification data is classified by stage identification. The specific operation is to use a data classification algorithm, such as the K-Means clustering algorithm, to classify the production stage identification data according to the similarity of timestamps to obtain production stage identification categories. For example, when setting the number of clustering centers to 3, the data points are divided into the production stage categories represented by the nearest clustering centers by calculating the distance between each production stage identification data and the clustering centers. Then, the production stages are divided by the production stage identification categories, and each stage includes all relevant production data within that stage. The state of the chemical production stage data is identified for the chemical production stage. Specifically, the decision tree algorithm in the machine learning algorithm is used to classify and analyze the chemical production stage data, and the state of each production stage is identified according to parameters such as the vibration frequency of the equipment, the motor current, and the equipment operation duration. The chemical reaction conditions of the chemical products are detected for the chemical production stage state data, which includes the chemical reaction conditions of each production stage, such as reaction temperature, reaction pressure, reactant concentration, etc. The reaction conditions indicators of the production stage are judged for the stage chemical reaction data. Specifically, by setting thresholds, such as the normal range of reaction temperature is 80°C - 120°C, it is judged whether the chemical reaction conditions of each production stage are within the normal range. The chemical reaction index benchmarks of the production stage are determined according to the chemical reaction conditions indicators, which includes the chemical reaction index benchmark values of each production stage, such as the reaction temperature benchmark value, the reaction pressure benchmark value, etc. The abnormal detection of the stage chemical reaction index is carried out for the stage chemical reaction data. Specifically, statistical analysis methods, such as standard deviation analysis, are used to calculate the deviation between the chemical reaction index of each production stage and the stage chemical reaction index benchmark value. The production index offset amount is measured for the reaction index abnormal data according to the stage chemical reaction index benchmark, which includes the offset amount of each abnormal data, such as the reaction temperature offset amount, the reaction pressure offset amount, etc.

[0099] Step S33: Identify the operation working mode from the stage equipment operation data to obtain operation working mode data; map the operation working mode data to the equipment operation working state to generate equipment operation state data;
[0100] Step S34: Detect the abnormal operation of the equipment from the equipment operation state data to obtain equipment abnormal operation data.
[0101] In the embodiments of the present invention, image recognition and sensor data fusion technology are used to identify the characteristics of production equipment for standard chemical production data. Specifically, through intelligent cameras and various sensors installed at the production site, such as temperature sensors, pressure sensors, flow sensors, etc., images and operation parameter data of production equipment are collected in real time; using image processing algorithms, such as edge detection, feature extraction, etc., the contours and key components of production equipment are identified from the images collected by the cameras, and at the same time, combined with sensor data, the operation parameters of production equipment are extracted, such as the vibration frequency of the equipment, motor current, equipment operation duration, etc. Then, equipment operation parameters are extracted from these characteristic data, which include information such as equipment ID, parameter name, parameter value, acquisition time, etc. To determine the production stage of production index offset data, specifically through the timestamp matching algorithm, the timestamp in the production index offset data is compared with the production stage timestamp in the standard chemical production data to determine the production stage where each offset data is located; according to the data in the offset stage, the operation characteristics of the equipment in the stage are matched with the operation data of the production equipment. Specifically, the association rule mining algorithm, such as the Apriori algorithm, is used to analyze the association relationship between the data in the offset stage and the operation data of the production equipment; if the reaction temperature offset value exceeds 5°C in a certain production stage, then the operation data of the equipment vibration frequency and motor current in this stage are matched, which includes information such as equipment ID, production stage, matching parameter name, matching parameter value, etc. To identify the operation working mode of the equipment operation data in the stage, specifically using the clustering algorithm in machine learning algorithms, such as the K-Means algorithm, to classify and analyze the equipment operation data in the stage, and according to parameters such as the vibration frequency of the equipment, motor current, equipment operation duration, etc., identify the operation working mode of the equipment in each production stage; for example, set the number of clustering centers to 3, and by calculating the distance between the equipment operation data in each stage and the clustering center, divide the data points into the operation working mode categories represented by the nearest clustering center; map the operation working mode data to the equipment operation working state, specifically by setting mapping rules, such as mapping a certain operation working mode to the normal operation state, and another mode to the standby state, etc., to generate equipment operation state data, which includes information such as equipment ID, production stage, operation working mode, operation working state, etc. To detect abnormal operation of the equipment based on the equipment operation state data. Specifically, statistical analysis methods, such as standard deviation analysis, are used to calculate the deviation between the equipment operation parameters in each production stage and the normal operation parameters to obtain equipment abnormal operation data. For example, if the deviation of the equipment vibration frequency exceeds the set threshold, such as exceeding 10% of the normal value, it is determined that the equipment has abnormal operation in this production stage and is recorded as equipment abnormal operation data.
[0102] Preferably, step S34 includes the following steps:
[0103] Step S341: Classify the device operation status data according to the devices in the operation stage to obtain device type data; Correspond the device type data to the devices in the chemical production stage to generate stage-corresponding device data;

[0106] Step S344: Detect the abnormal centrifugal speed of the device for the rotating centrifugal device parameters to obtain the parts of the device with abnormal speed; Identify the abnormal jitter state of the device for the parts of the device with abnormal speed to generate device abnormal jitter data;
[0107] Step S345: Integrate the abnormal temperature area of the device and the device abnormal jitter data to obtain device abnormal operation data.
[0108] In the embodiments of the present invention, data classification technology is used to classify equipment in the operation stage according to the operation status data of the equipment. Specifically, through the decision tree algorithm in machine learning algorithms, the equipment in the equipment operation status data is classified according to features such as the model, production capacity, and maintenance records of the equipment. For example, the equipment is classified into types such as reaction kettles, centrifuges, and compressors; the equipment type data is corresponded to the equipment in the chemical production stage. Specifically, through the timestamp matching and equipment type matching algorithms, the equipment type data is corresponded to the production stage in the standard chemical production data, which includes information such as equipment ID, equipment type, production stage, and operation status; the equipment data corresponding to the stage is used to determine the chemical production process operations. Specifically, through the process flow analysis algorithm, according to the process steps and equipment functions in the chemical production process, the process operations of each stage corresponding equipment are determined to obtain equipment process operation data. For example, the process operation of a reaction kettle in a certain production stage is heating reaction, and the process operation of a centrifuge is separation and purification. Then, the chemical equipment temperature is identified from the equipment process operation data. The specific operation is to collect the temperature data of the equipment during the process operation through a temperature sensor, and combine the process operation requirements to identify the temperature change of the equipment to obtain chemical equipment temperature data, which includes information such as equipment ID, production stage, process operation, and temperature value. The abnormal temperature area of the chemical equipment is located from the chemical equipment temperature data. Specifically, through thermal imaging technology or temperature distribution analysis algorithm, according to the temperature data of the equipment and the normal operating temperature range, the abnormal temperature area on the surface or inside of the equipment is located to obtain the abnormal temperature area of the equipment; if the temperature of a local area of a reaction kettle rises abnormally, the area can be accurately located through a thermal imaging map. Then, the chemical rotation centrifuge equipment parameters are detected according to the abnormal temperature area of the equipment from the equipment operation status data. The specific operation is that for a rotating centrifuge equipment, through a vibration sensor and a speed sensor, the operation parameters of the equipment in the abnormal temperature area, such as vibration amplitude and speed, are detected to generate rotating centrifuge equipment parameters. The abnormal centrifugal speed of the rotating centrifuge equipment is detected from the rotating centrifuge equipment parameters. By setting a speed threshold, such as the normal speed range is 1000 - 1500 revolutions per minute, it is detected whether the actual speed of the rotating centrifuge equipment exceeds the normal range. For example, if the actual speed of a centrifuge is 1600 revolutions per minute, exceeding the normal range, it is determined that there is a speed abnormality in this equipment part. Then, the abnormal jitter state of the equipment part with abnormal speed is identified. The vibration data of the equipment part with abnormal speed is collected through a vibration sensor, and the vibration frequency and amplitude are analyzed to identify the abnormal jitter state of the equipment to generate equipment abnormal jitter data. Through data fusion technology, the equipment abnormal temperature area data and the equipment abnormal jitter data are integrated to generate equipment abnormal operation data, which includes information such as equipment ID, production stage, abnormal type (temperature abnormality or jitter abnormality), abnormal part, and abnormal parameter value.

Specifically, through the decision tree algorithm in machine learning algorithms, according to features such as indicator names, offsets, and offset times in the production indicator offset data, the offset indicators are classified. For example, the offset indicators are classified into types such as temperature offset, pressure offset, and flow offset. Then, production offset optimization control is performed on the products in the chemical production process according to the offset indicator type data. Specifically, through the PID control algorithm, the corresponding production parameters are adjusted according to the offset indicator type and the offset amount. If the temperature offset exceeds 5°C, the power of the heater is adjusted to bring the temperature back to the normal range, including information such as the parameter name to be adjusted, the adjustment amplitude, and the adjustment time. Equipment temperature anomaly response control is performed on the equipment abnormal temperature area. Specifically, through the temperature control system, according to the data of the equipment abnormal temperature area, such as the location of the abnormal area and the temperature value, the corresponding cooling or heating device is started. For example, if the temperature of a local area of a certain equipment rises abnormally, the cooling water circulation system is started to lower the temperature of this area, and equipment temperature anomaly response measures are generated, including information such as the response equipment ID, the description of the response measure, and the response time. Equipment abnormal vibration response control is performed on the equipment abnormal vibration data. Specifically, through the vibration control system, according to parameters such as the vibration frequency and vibration amplitude in the equipment abnormal vibration data, the operating parameters of the equipment are adjusted, such as adjusting the balance device or shock absorption device of the equipment, and equipment abnormal vibration response measures are obtained. For example, if the vibration amplitude of the equipment exceeds the set threshold, the shock pads of the equipment are adjusted to reduce the vibration amplitude. Chemical production control is performed on the chemical production equipment according to the production offset optimization measures and the equipment abnormal operation response measures. The specific operation is to integrate the production offset optimization measures and the equipment abnormal operation response measures into the control strategy through the automation control system, and monitor various parameters in the production process in real time. When the parameters reach the trigger conditions, the corresponding optimization measures or response measures are automatically executed. Then, a chemical production control model is constructed based on the chemical production control data. The specific operation is to use data modeling technology to take the chemical production control data as input and construct a chemical production control model. The production offset optimization measures and the equipment abnormal operation response measures are used to train the chemical production control pre-model. Specifically, the production offset optimization measures and the equipment abnormal operation response measures are used as training data to train the chemical production control pre-model, and a chemical production control training model is obtained, which contains information such as the weights, biases, and classification surfaces of the model.

For example, by analyzing the labels and value ranges in the data, the reaction conversion rate offset data and product quality offset data are respectively marked out; the reaction catalyst for the reaction conversion rate offset data is determined. The specific operation is to determine the catalyst type related to the reaction conversion rate offset by analyzing the chemical reaction mechanism and combining the catalyst usage records in the production process. Then, the dosage of the reaction catalyst data is detected, and the actual dosage of the catalyst is measured through an on-line analyzer or laboratory analysis method. For example, a spectral analyzer is used to detect the concentration of the catalyst to obtain specific dosage values. The conversion rate offset amount of the reaction conversion rate offset data is determined. Specifically, the actual conversion rate is compared with the target conversion rate, and the offset amount of the conversion rate is calculated to generate the conversion rate offset amount. The addition amount of the chemical production catalyst is determined for the reaction catalyst dosage according to the conversion rate offset amount. Specifically, through the chemical reaction kinetics model and combining the conversion rate offset amount, the addition amount of the catalyst that needs to be adjusted is calculated to obtain the production catalyst addition amount. For example, if the conversion rate offset amount is -5%, it is calculated according to the model that 10% more catalyst dosage is needed. The chemical production process product is controlled for the chemical catalyst dosage according to the production catalyst addition amount. Specifically, through an automated control system, according to the calculated catalyst addition amount, the catalyst supply system is adjusted. For example, the flow rate of the catalyst supply pump is adjusted, and the addition data is recorded. The product impurity type of the product quality offset data is determined. The specific operation is to analyze the impurity components in the product quality offset data through a quality analyzer, such as a chromatograph or a mass spectrometer, to obtain the product impurity type data.

The impurity neutralizer is added to the chemical production process product according to the impurity type content. The specific operation is to select a suitable neutralizer according to the impurity type and content, and through an automated control system, the neutralizer is accurately added to obtain the impurity neutralizer addition data. For example, if it is detected that the product contains excessive acidic impurities, the corresponding alkaline neutralizer is added, and the addition data is recorded.

[0131] In the embodiment of the present invention, thermal imaging processing of the equipment area is performed on the abnormal temperature area of the equipment. The specific operation is to use a thermal imaging camera to scan the abnormal temperature area of the equipment to generate an equipment thermal imaging map. The thermal imaging camera detects the temperature distribution on the surface of the equipment through infrared rays, converts the temperature data into an image form, and obtains the equipment thermal imaging map. Then, the abnormal temperature distribution in the equipment thermal imaging map is identified. The specific operation is to identify the areas with abnormal temperatures in the map through image processing algorithms such as edge detection and region segmentation, and generate abnormal temperature distribution data, which includes information such as the positions and temperature values of the abnormal areas. Equipment detection affected by temperature is performed on the chemical production equipment according to the abnormal temperature distribution data. The specific operation is to determine the equipment affected by temperature through the equipment management system, combining the positions and temperature values in the abnormal temperature distribution data, and obtain the temperature abnormal influence data. For example, if the temperature of a local area of a certain equipment rises abnormally, query the equipment corresponding to this area through the equipment management system and record it as the equipment affected by temperature. Identification of the structural positions of the equipment affected by the temperature abnormal influence data is performed. The specific operation is to determine the specific structural positions of the equipment affected by combining the position information in the temperature abnormal influence data with the three-dimensional model or drawings of the equipment. Then, judgment of the degree of influence of temperature on the structural position data of the equipment affected is performed. The specific operation is to judge the degree of influence of temperature on the equipment through the relationship model between temperature and equipment performance, combining the temperature values in the structural position data of the equipment affected, and obtain the degree of influence of temperature. For example, if the temperature of a certain component of an equipment exceeds 20% of its normal operating temperature range, it is judged that the degree of influence of this component by temperature is severe. Starting of the equipment position cooling system is performed on the chemical production equipment based on the structural position data of the equipment affected. Specifically, through the automatic control system, the corresponding cooling system is started according to the structural position data of the equipment affected. For example, if the temperature of a certain component of an equipment is abnormal, start the cooling fan or cooling water circulation system near this component, and record the start time and status of the cooling system. Control of the gear position of the equipment cooling system is performed on the chemical production equipment based on the degree of influence of temperature. The specific operation is to adjust the gear position of the cooling system according to the degree of influence of temperature. For example, if the degree of influence of the equipment by temperature is severe, adjust the gear position of the cooling system to the highest, and record the adjusted gear position and time. Equipment temperature abnormal response control is performed according to the cooling system start data and the equipment cooling control data. The specific operation is to integrate the cooling system start data and the equipment cooling control data into the control strategy through the automatic control system, and monitor the temperature change of the equipment in real time. When the temperature reaches the set safe range, automatically adjust the operating state of the cooling system to obtain the equipment temperature abnormal response measures. For example, when the equipment temperature drops to the normal range, automatically reduce the gear position of the cooling system or stop the cooling system, and record the execution time and effect of the response measures.
[0132] Preferably, step S43 includes the following steps:
[0133] Step S431: Detect the jitter frequency of the abnormal jitter data of the equipment to obtain the abnormal jitter frequency value; measure the operating speed of the chemical production equipment according to the abnormal jitter frequency value, and generate the operating speed data of the jitter equipment;
[0134] Step S432: Monitor the equipment load condition of the operating speed data of the jitter equipment to obtain the load data of the jitter equipment; record the abnormal load of the load data of the jitter equipment to generate the abnormal load data of the equipment;
[0135] Step S433: Extract the rotational speed load value from the abnormal load data of the equipment to obtain the abnormal rotational speed load value; reduce the rotational speed of the equipment gear transmission of the chemical production equipment based on the abnormal rotational speed load value, and generate the gear rotational speed adjustment data;
[0136] Step S434: Reduce the centrifugal rotational speed of the chemical production equipment based on the abnormal rotational speed load value, and generate the centrifugal rotational speed adjustment data;
[0137] Step S435: Control the abnormal jitter response of the chemical production equipment according to the gear rotational speed adjustment data and the centrifugal rotational speed adjustment data to obtain the abnormal jitter response measures of the equipment.
[0138] In the embodiments of the present invention, for the abnormal jitter data of the device, the jitter frequency is detected. Specifically, a vibration sensor is used to collect the vibration signal of the device, and the time-domain signal is converted into a frequency-domain signal through Fourier transform. For example, a spectrum analyzer is used to analyze the vibration signal to determine the main jitter frequency components. The operating speed of the chemical production equipment is measured according to the abnormal jitter frequency value. Specifically, through a speed sensor or an encoder, the operating speed of the device is measured to generate the operating speed data of the jitter device. For example, for a rotating device, its rotational speed is measured by an encoder and recorded as the operating speed data of the jitter device. The load condition of the jitter device during operation is monitored for the operating speed data of the jitter device. Specifically, through a current sensor or a torque sensor, the load condition of the device during operation is monitored. For example, the current of the motor is measured by a current sensor to estimate the load of the device. Abnormal load records are made for the load data of the jitter device. Specifically, a load threshold is set, and when the device load exceeds the threshold, it is recorded as abnormal load data. If the current during normal operation of the device is 10 A and the set threshold is 12 A, when the current exceeds 12 A, it is recorded as abnormal load data. The rotational speed load value is extracted from the abnormal load data of the device. Specifically, the load value related to the rotational speed is extracted from the abnormal load data to obtain the abnormal rotational speed load value. For example, the rotational speed and the corresponding current value of the device under abnormal load are recorded. Based on the abnormal rotational speed load value, the rotational speed of the gear drive of the chemical production equipment is reduced. The specific operation is to reduce the rotational speed of the gear drive of the device through a frequency converter or a speed governor according to the abnormal rotational speed load value to generate gear rotational speed adjustment data. For example, if the abnormal rotational speed load value indicates that the device rotational speed is too high, the rotational speed is reduced through a frequency converter, and the adjusted rotational speed and time are recorded. Based on the abnormal rotational speed load value, the centrifugal rotational speed of the chemical production equipment is reduced. The specific operation is that for a centrifugal device, by adjusting the control parameters of the centrifuge, such as voltage or frequency, the centrifugal rotational speed is reduced. For example, if the abnormal rotational speed load value of the centrifuge indicates that the rotational speed needs to be reduced, the rotational speed is reduced by adjusting the power supply frequency, and the adjusted rotational speed and time are recorded. According to the gear rotational speed adjustment data and the centrifugal rotational speed adjustment data, the abnormal jitter response control of the chemical production equipment is performed. Specifically, through an automated control system, the gear rotational speed adjustment data and the centrifugal rotational speed adjustment data are integrated into the control strategy to monitor the jitter condition of the device in real time. When the jitter frequency or load returns to normal, the operating state of the device is automatically adjusted to obtain the abnormal jitter response measures of the device. For example, when the jitter frequency of the device drops to the normal range, the rotational speed and load of the device are automatically adjusted, and the execution time and effect of the response measures are recorded.
