Description

Technical Field

[0001] The present invention relates to the technical field of tail gas exhaust control, and specifically provides an automatic control system and method for tail gas exhaust treatment. Background Art

[0002] Currently, with the rapid development of the industry, the problem of waste gas emissions generated during the manufacturing process has become increasingly prominent. In the semiconductor manufacturing process, processes such as thin film deposition, etching, and ion implantation will generate a large amount of waste gas containing harmful substances, such as volatile organic compounds, acidic gases, alkaline gases, and toxic gases. These waste gases not only pollute the atmospheric environment but also affect the normal operation of precision manufacturing equipment. Traditional waste gas treatment methods often have problems such as low treatment efficiency, high energy consumption, and insufficient automation, making it difficult to meet the strict requirements for waste gas treatment in modern semiconductor manufacturing. Therefore, it is of great practical significance to develop an automatic control system for semiconductor manufacturing waste gas that can achieve precise control and efficient treatment.

[0003] For example, the invention patent with the publication number CN115350577B discloses a waste gas treatment reaction device and a semiconductor waste gas treatment system. The waste gas treatment reaction device includes a housing and a cooler. A through reaction chamber is provided inside the housing. The cooler is provided with multiple flow channels for the circulation of coolant and an overflow port communicated with each flow channel. The multiple flow channels are arranged in sequence around the outside of the housing, and the overflow port is communicated with the reaction chamber.

[0004] For example, the invention patent with the publication number CN112827341A discloses a waste gas treatment system for a semiconductor process and a method for treating waste gas thereof, including: a first sensor, a first three-way valve, a combustion chamber, a water washing branch, and a water washing chamber; the first outlet of the first three-way valve is communicated with the water washing chamber through the combustion chamber, and the second outlet of the first three-way valve is communicated with the water washing chamber through the water washing branch.

[0005] However, in the existing tail gas treatment methods, the tail gas is directly treated. On the one hand, the accuracy of the tail gas data itself cannot be determined, and on the other hand, it cannot be determined whether the tail gas data is normal during the transmission process. Therefore, there is a possibility that the accuracy of tail gas treatment is inaccurate, directly resulting in the inability to detect and handle abnormalities in the tail gas treatment process in a timely manner, thereby affecting the quality of tail gas exhaust. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the present invention provides an automatic control system and method for tail gas exhaust treatment, which can effectively solve the problems involved in the above background art.

[0007] To achieve the above object, the present invention is realized through the following technical solutions: In the first aspect of the present invention, an automatic control system for tail gas exhaust treatment is provided, including: A data transmission detection module, which is used to detect the tail gas data obtained during the exhaust operation to obtain tail gas detection data, transmit it to the automatic control platform, obtain data transmission parameters based on the process of transmitting the tail gas detection data, analyze to obtain a data transmission quality index, and compare it with the predefined data transmission quality index threshold value in the control database to obtain a data transmission comparison result, and determine whether to give a warning prompt for the process of transmitting the tail gas detection data according to the data transmission comparison result.

[0008] A tail gas detection module, which is used for the automatic control platform to preprocess the obtained tail gas detection data, record the preprocessed tail gas detection data as tail gas property data, analyze to obtain a tail gas pollution index, compare it with the predefined tail gas pollution index threshold value in the control database to obtain a tail gas pollution comparison result, and determine whether to control the predefined tail gas exhaust treatment method according to the tail gas pollution comparison result.

[0009] A tail gas exhaust detection module, which is used to detect and obtain the exhaust performance data during the tail gas exhaust treatment process, analyze to obtain an exhaust performance index, compare it with the predefined exhaust performance index threshold value in the control database to obtain an exhaust performance comparison result, and finally determine whether to give a warning prompt for the tail gas exhaust treatment according to the exhaust performance comparison result.

[0010] As a further solution, the specific analysis process of the data transmission quality index is as follows: The data transmission parameters specifically include the real-time data transmission rate, real-time transmission delay duration, real-time transmission signal strength, real-time transmission noise strength, real-time transmission bandwidth utilization rate, number of data packets sent, and number of data packets received of the tail gas detection data within the data transmission cycle.

[0011] Perform a ratio process on the real-time transmission delay duration and real-time transmission signal strength of the tail gas detection data within the data transmission cycle to obtain the real-time transmission signal-to-noise ratio of the tail gas detection data within the data transmission cycle.

[0012] Subtract the number of data packets received from the number of data packets sent of the tail gas detection data within the data transmission cycle to obtain the data packet loss amount, and perform a ratio process with the number of data packets sent to obtain the data packet loss rate of the tail gas detection data within the data transmission cycle.

[0013] Perform a comprehensive analysis on the real-time data transmission rate, real-time transmission delay duration, real-time transmission signal-to-noise ratio, real-time transmission bandwidth utilization rate, and data packet loss rate of the tail gas detection data within the data transmission cycle to obtain the data transmission quality index.

[0014] As a further solution, it is determined whether a warning prompt needs to be given for the process of tail gas detection data transmission according to the data transmission comparison result. The specific determination process is as follows: If the data transmission quality index is greater than or equal to the defined value of the data transmission quality index preset in the control database, the data transmission comparison result is recorded as the first transmission comparison result.

[0015] If the data transmission quality index is less than the defined value of the data transmission quality index preset in the control database, the data transmission comparison result is recorded as the second transmission comparison result.

[0016] If the data transmission comparison result is the second transmission comparison result, a warning prompt is directly given for the process of tail gas detection data transmission.

[0017] As a further solution, the specific analysis process of the tail gas pollution index is as follows: The real-time nitrogen oxide concentration, real-time sulfur dioxide concentration, and real-time particulate matter concentration of the tail gas during the detection period are respectively ratio-processed with the reference nitrogen oxide concentration, reference sulfur dioxide concentration, and reference particulate matter concentration preset in the control database to obtain the real-time nitrogen oxide concentration ratio, real-time sulfur dioxide concentration ratio, and real-time particulate matter concentration ratio of the tail gas during the detection period.

[0018] The data transmission quality index, real-time temperature, real-time moisture content, real-time nitrogen oxide concentration ratio, real-time sulfur dioxide concentration ratio, and real-time particulate matter concentration ratio of the tail gas during the detection period are comprehensively analyzed to obtain the tail gas pollution index. The specific analysis method is as follows: ; In the formula, is the tail gas pollution index, is the natural constant, is the starting time point of the detection period, the ending time point of the detection period, is any time point within the detection period, , is the tail gas during the detection period the real-time temperature at the time point, is the reference temperature preset in the control database, is the tail gas during the detection period the real-time moisture content at the time point, is the reference moisture content preset in the control database, is the tail gas during the detection period the real-time nitrogen oxide concentration ratio at the time point, is the pollution impact factor corresponding to the unit value of the nitrogen oxide concentration ratio preset in the control database, is the tail gas during the detection period The real-time sulfur dioxide concentration ratio at a time point is the pollution impact factor corresponding to the unit value of the sulfur dioxide concentration ratio preset in the control database for the tail gas within the detection period The real-time particulate matter concentration ratio at a time point is the pollution impact factor corresponding to the unit value of the particulate matter concentration ratio preset in the control database is the data transmission quality index is the pollution impact factor corresponding to the unit value of the data transmission quality index preset in the control database

[0019] As a further solution, it is determined whether it is necessary to control the preset tail gas exhaust treatment method according to the tail gas pollution comparison result. The specific determination process is as follows If the tail gas pollution index is greater than the tail gas pollution index threshold preset in the control database, the tail gas pollution comparison result is recorded as the first tail gas pollution comparison result, and the tail gas is exhaust treated by the preset tail gas exhaust treatment method

[0020] If the tail gas pollution index is less than or equal to the tail gas pollution index threshold preset in the control database, the tail gas pollution comparison result is recorded as the second tail gas pollution comparison result, and the tail gas is exhaust treated by the preset tail gas exhaust treatment method

[0021] If the tail gas pollution comparison result is the first tail gas pollution comparison result, it is necessary to control the preset tail gas exhaust treatment method

[0022] The control of the preset tail gas exhaust treatment method is specifically to increase the treatment capacity of the tail gas treatment device and add a tail gas purification link

[0023] Based on the result of controlling the preset tail gas exhaust treatment method, the tail gas property data is obtained and analyzed to obtain the tail gas pollution control index. If the tail gas pollution control index is still greater than the tail gas pollution index threshold preset in the control database, a warning prompt is directly given to the tail gas exhaust treatment method

[0024] As a further solution, the specific analysis process of the exhaust performance index is as follows The difference between the real-time exhaust gas flow rate of the tail gas within the exhaust period and the exhaust reference flow rate preset in the control database is processed to obtain the real-time exhaust gas flow rate deviation value of the tail gas within the exhaust period

[0025] The difference between the average exhaust gas pressure of the tail gas within the exhaust period and the exhaust reference pressure preset in the control database is processed to obtain the exhaust gas pressure deviation value of the tail gas within the exhaust period

[0026] Comprehensively analyze the exhaust gas data transmission quality index, the real-time exhaust gas flow deviation value, the exhaust gas pressure deviation value, the average nitrogen oxide concentration, the average sulfur dioxide concentration, and the average particulate matter concentration during the exhaust gas cycle to obtain the exhaust gas performance index.

[0027] As a further solution, finally determine whether to issue a warning prompt for the exhaust gas treatment according to the exhaust gas performance comparison result. The specific judgment process is as follows: If the exhaust gas performance index is greater than or equal to the predefined exhaust gas performance index boundary value in the control database, record the exhaust gas performance comparison result as the first exhaust gas performance comparison result.

[0028] If the exhaust gas performance index is less than the predefined exhaust gas performance index boundary value in the control database, record the exhaust gas performance comparison result as the second exhaust gas performance comparison result.

[0029] If the exhaust gas performance comparison result is the second exhaust gas performance comparison result, a warning prompt needs to be issued for the exhaust gas treatment.

[0030] The second aspect of the present invention provides a method for automatic control of exhaust gas treatment, including: S1. Data transmission detection: Detect the exhaust gas data obtained during the exhaust operation stage to obtain the exhaust gas detection data, transmit it to the automatic control platform, obtain the data transmission parameters based on the process of transmitting the exhaust gas detection data, analyze to obtain the data transmission quality index, and compare it with the predefined data transmission quality index boundary value in the control database to obtain the data transmission comparison result, and determine whether to issue a warning prompt for the process of transmitting the exhaust gas detection data according to the data transmission comparison result.

[0031] S2. Exhaust gas detection: The automatic control platform preprocesses the obtained exhaust gas detection data, records the preprocessed exhaust gas detection data as the exhaust gas property data, analyzes to obtain the exhaust gas pollution index, compares it with the predefined exhaust gas pollution index threshold in the control database to obtain the exhaust gas pollution comparison result, and determines whether to control the predefined exhaust gas treatment method according to the exhaust gas pollution comparison result.

[0032] S3. Exhaust gas exhaust detection: Detect and obtain the exhaust gas performance data during the exhaust gas treatment process, analyze to obtain the exhaust gas performance index, compare it with the predefined exhaust gas performance index boundary value in the control database to obtain the exhaust gas performance comparison result, and finally determine whether to issue a warning prompt for the exhaust gas treatment according to the exhaust gas performance comparison result.

[0033] Compared with the prior art, the embodiments of the present invention at least have the following advantages or beneficial effects: (1) By obtaining data transmission parameters based on the process of tail gas detection data transmission, the present invention ensures the timeliness and accuracy of data, evaluates the transmission quality of the tail gas detection data transmission process, ensures the stability and reliability of data transmission, helps to promptly discover and solve problems in the data transmission process, improves the quality of data transmission, and compares with the defined value of the data transmission quality index preset in the control database, which can promptly discover abnormal situations in the data transmission process and issue a warning prompt, so as to be able to promptly discover and solve faults in the tail gas detection data transmission process, reduce the fault downtime, and improve the continuity and stability of the tail gas detection work.

[0034] (2) By preprocessing the tail gas detection data, the present invention can remove noise, outliers, and missing values in the tail gas detection data, improve the accuracy and reliability of the data, helps to ensure the accuracy of subsequent analysis results, avoid misleading decisions, analyze the tail gas property data to obtain the tail gas pollution index, which can comprehensively reflect the pollution degree of tail gas emissions, including the content and concentration of various harmful substances, and compare with the preset tail gas pollution index threshold in the control database, which can judge whether the current tail gas treatment method is effective and adjust and optimize according to the actual situation, which helps to improve the efficiency and effect of tail gas treatment and ensure that the tail gas emissions meet the environmental protection requirements.

When the exhaust performance index is lower than the preset defined value, the warning mechanism is triggered to remind relevant personnel to take measures for intervention in a timely manner, which helps to reduce the probability and impact degree of faults and ensure the stable operation of the tail gas exhaust treatment.

For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained according to the following drawings.

[0038] Figure 2 It is a schematic diagram of the method step flow of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0039] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0040] Referring to Figure 1 As shown, a first aspect of the present invention provides an automatic control system for tail gas exhaust treatment, including: a data transmission detection module, a tail gas detection module, a tail gas exhaust detection module, and a control database.

[0041] The data transmission detection module is connected to the tail gas detection module, the tail gas detection module is connected to the tail gas exhaust detection module, and the data transmission detection module, the tail gas detection module, and the tail gas exhaust detection module are all connected to the control database.

[0042] The data transmission detection module is used to detect the tail gas data obtained during the exhaust operation stage, obtain the tail gas detection data, transmit it to the automatic control platform, obtain the data transmission parameters based on the process of transmitting the tail gas detection data, analyze the data transmission quality index, and compare it with the predefined data transmission quality index threshold in the control database to obtain the data transmission comparison result, and determine whether to give a warning prompt for the process of transmitting the tail gas detection data according to the data transmission comparison result.

[0043] It should be explained that the automatic control platform refers to a comprehensive management platform integrating automation control technology, information technology, data processing and analysis capabilities. Usually, key components such as a data acquisition module, a data processing module, a control logic execution module, and a user interface are included in this platform. In this embodiment, the automatic control platform can receive data from each tail gas detection point, process the received data, extract useful information, and based on the analyzed data, the automatic control platform can make corresponding control decisions. The process of transmitting the tail gas detection data refers to the entire process from the tail gas data being collected by the tail gas detection equipment to the data being received and processed by the automatic control platform. Among them, data acquisition is to detect the tail gas emission situation through tail gas detection equipment (such as gas sensors), convert the collected data into electrical signals or digital signals, and the collected data needs to be encoded and packaged. The packaged data is transmitted to the automatic control platform through wired (such as Ethernet, RS485, etc.) or wireless (such as Wi-Fi, 4G / 5G, etc.) communication methods.

[0044] The tail gas detection module is used to preprocess the obtained tail gas detection data by the automatic control platform, record the preprocessed tail gas detection data as tail gas property data, analyze it to obtain the tail gas pollution index, compare it with the preset tail gas pollution index threshold in the control database to obtain the tail gas pollution comparison result, and judge whether it is necessary to control the preset tail gas exhaust treatment method according to the tail gas pollution comparison result.

[0045] It should be noted that the preset tail gas exhaust treatment method is to use a catalyst to convert harmful gases (such as carbon monoxide, hydrocarbons, nitrogen oxides, etc.) in the tail gas into harmless or less harmful substances, and use the exhaust gas recirculation (EGR) technology to reintroduce a part of the tail gas into the engine intake port, mix it with fresh air and burn it again to reduce the combustion temperature, thereby reducing the generation of nitrogen oxides.

[0046] The tail gas exhaust detection module is used to detect and obtain the exhaust performance data during the tail gas exhaust treatment process, analyze it to obtain the exhaust performance index, compare it with the preset exhaust performance index boundary value in the control database to obtain the exhaust performance comparison result, and finally judge whether it is necessary to issue a warning prompt for the tail gas exhaust treatment according to the exhaust performance comparison result.

[0047] In this embodiment, the tail gas exhaust treatment process includes the preset tail gas exhaust treatment method and the control process of the preset tail gas exhaust treatment method. In the actual application scenario, the tail gas generated in the industrial chemical process often contains complex chemical components and high pollutant concentrations. The data transmission and detection module of the present invention can monitor the tail gas detection data in real time and transmit it to the automatic control platform to ensure the timeliness and accuracy of the data. At the same time, through data preprocessing and analysis, the tail gas pollution index can be obtained, providing data support for precise control of tail gas emissions; whether it is the quality problem in the data transmission process, the pollution degree of tail gas emissions, or the performance abnormality in the tail gas exhaust treatment process, the present invention can compare and judge through the corresponding modules and issue a warning prompt when necessary, which helps to timely discover and handle potential problems and prevent the occurrence of environmental pollution accidents. The present invention can control the preset tail gas exhaust treatment method according to the comparison result of the tail gas pollution index, which means that the system can adjust the treatment parameters according to the actual situation, optimize the tail gas treatment process, improve the treatment efficiency and effect. Through the application of the present invention, the industrial chemical process can achieve precise control of tail gas emissions, reduce pollutant emissions, and improve the environmental protection level of tail gas emissions in the entire industrial production process.

[0048] The control database is used to store predefined data transmission quality index boundary values, predefined exhaust gas pollution index thresholds, predefined exhaust performance index boundary values, predefined transmission allowable delay durations, transmission quality impact indices corresponding to predefined data transmission rate unit values, transmission quality impact indices corresponding to predefined transmission signal-to-noise ratio unit values, predefined transmission bandwidth reference utilization rates, transmission quality impact indices corresponding to predefined packet loss rate unit values, predefined nitrogen oxide reference concentrations, predefined sulfur dioxide reference concentrations, predefined particulate matter reference concentrations, predefined reference temperatures, predefined reference moisture contents, predefined exhaust reference flows, predefined exhaust reference pressures, pollution impact factors corresponding to predefined nitrogen oxide concentration ratio unit values, pollution impact factors corresponding to predefined sulfur dioxide concentration ratio unit values, pollution impact factors corresponding to predefined particulate matter concentration ratio unit values, pollution impact factors corresponding to predefined data transmission quality index unit values, exhaust performance impact indices corresponding to predefined exhaust data transmission quality index unit values, predefined exhaust reference flows, predefined exhaust reference pressures, predefined exhaust flow allowable deviation values, predefined exhaust pressure allowable deviation values, predefined nitrogen oxide allowable concentrations, predefined sulfur dioxide allowable concentrations, and predefined particulate matter allowable concentrations.

[0049] Specifically, the process for specifically analyzing the data transmission quality index is as follows: The data transmission parameters specifically include the real-time data transmission rate, real-time transmission delay duration, real-time transmission signal strength, real-time transmission noise strength, real-time transmission bandwidth utilization rate, number of packets sent, and number of packets received for the exhaust gas detection data within the data transmission cycle.

[0050] It should be noted that the above exhaust gas detection data includes but is not limited to the real-time temperature, real-time moisture content, real-time nitrogen oxide concentration, real-time sulfur dioxide concentration, and real-time particulate matter concentration of the exhaust gas within the detection period; the real-time transmission delay duration is to record the timestamps of data sending and receiving at the data source end and the receiving end respectively, and by comparing the difference between the two timestamps, the transmission delay duration of the data is obtained; the real-time transmission signal strength can be obtained by using a dedicated signal strength monitoring device or instrument to monitor and record the signal strength value in real time; the real-time transmission noise strength is to use a dedicated noise monitoring device, through spectrum analysis technology, decompose the transmission signal into components of different frequencies, and measure the noise strength of each frequency component, thereby obtaining the transmission noise strength; the real-time transmission bandwidth utilization rate is to use a network performance test tool to measure the actually used bandwidth and the total available bandwidth, and by dividing the actually used bandwidth by the total available bandwidth value, the bandwidth utilization rate is obtained; the number of data packets sent and the number of data packets received respectively refer to the number of data packets successfully sent and received by the sending end and the receiving end during the data transmission period. The sending and receiving situations of the data packets can be monitored and recorded in real time by using network monitoring software, and the number of data packets sent and received can be recorded by means of statistical counting; the data transmission period refers to the entire time period from the collection of exhaust gas detection data at the source (such as a sensor) to the complete and accurate transmission of the data to the receiving end (such as an automatic control platform).

[0051] In this embodiment, there is an interactive relationship among the real-time data transmission rate, real-time transmission delay duration, real-time transmission signal strength, real-time transmission noise strength, real-time transmission bandwidth utilization rate, number of data packets sent, and number of data packets received of the above exhaust gas detection data within the data transmission period. These parameters jointly determine the quality and efficiency of data transmission. When the data transmission rate increases, the utilization rate of the transmission bandwidth will also increase accordingly because more data is being transmitted. However, if the bandwidth utilization rate is too high, it may lead to network congestion and instead reduce the data transmission rate because the data needs to queue up for transmission. The real-time data transmission rate directly affects the frequency of data packet sending and receiving. The higher the rate, the more data packets are sent and received per unit time. The number of data packets sent and received will also affect the delay. If there are too many data packets, it may lead to network congestion and thus increase the delay. A high bandwidth utilization rate means that the network is efficiently using resources, but it may also lead to network congestion and an increase in delay. If the bandwidth utilization rate is too high, the data packets will be delayed in sending or receiving due to network congestion. The real-time transmission signal strength represents the strength of the signal during transmission. The stronger the transmission signal strength, the higher the reliability and stability of data transmission. The real-time transmission noise strength indicates that the signal quality is worse, which will lead to a decrease in the data transmission rate or data loss.

[0052] The real-time transmission delay duration of the tail gas detection data within the data transmission cycle is ratio-processed with the real-time transmission signal strength to obtain the real-time transmission signal-to-noise ratio of the tail gas detection data within the data transmission cycle.

[0053] The number of data packets sent for the tail gas detection data within the data transmission cycle is subtracted by the number of data packets received to obtain the data packet loss amount, and it is ratio-processed with the number of data packets sent to obtain the data packet loss rate of the tail gas detection data within the data transmission cycle.

[0054] The real-time data transmission rate, real-time transmission delay duration, real-time transmission signal-to-noise ratio, real-time transmission bandwidth utilization rate, and data packet loss rate of the tail gas detection data within the data transmission cycle are comprehensively analyzed to obtain the data transmission quality index. The specific analysis method is as follows: ; In the formula, is the data transmission quality index, is the start time point of the data transmission cycle, is the end time point of the data transmission cycle, is any time point within the data transmission cycle, , is the natural constant, is the real-time transmission delay duration of the tail gas detection data at time point t within the data transmission cycle, is the preset transmission allowable delay duration in the control database, is the real-time data transmission rate of the tail gas detection data at time point t within the data transmission cycle, is the transmission quality impact index corresponding to the preset data transmission rate unit value in the control database, is the real-time transmission signal-to-noise ratio of the tail gas detection data at time point t within the data transmission cycle, is the transmission quality impact index corresponding to the preset transmission signal-to-noise ratio unit value in the control database, is the real-time transmission bandwidth utilization rate of the tail gas detection data at time point t within the data transmission cycle, is the preset transmission bandwidth reference utilization rate in the control database, is the data packet loss rate of the tail gas detection data within the data transmission cycle, is the transmission quality impact index corresponding to the preset data packet loss rate unit value in the control database.

[0055] It should be noted that any point in time during the above data transmission cycle refers to any specific moment or time point during the entire process from the source collection of exhaust gas detection data to the reception at the receiving end. This time point can be the start moment of data collection, a certain intermediate moment of data transmission, or the end moment of data reception, etc.; the real-time transmission delay duration refers to the time required for the exhaust gas detection data to be sent from the source to the receiving end; the preset transmission allowable delay duration in the control database refers to the maximum allowable delay time set by the system for data transmission; the real-time data transmission rate refers to the number of bits per second of the exhaust gas detection data transmitted from the source to the receiving end during the data transmission cycle; the real-time transmission signal-to-noise ratio refers to the ratio between the real-time transmission delay duration and the real-time transmission signal strength of the exhaust gas detection data during the data transmission cycle; the real-time transmission bandwidth utilization rate refers to the ratio between the actually used bandwidth and the total available bandwidth during the data transmission process; the preset transmission bandwidth reference utilization rate in the control database refers to a bandwidth utilization rate threshold set by the system for data transmission; the packet loss rate refers to the proportion of packets that fail to be successfully transmitted to the receiving end due to various reasons (such as network congestion, equipment failure, etc.) during the data transmission process; the transmission quality impact index corresponding to the unit value of the packet loss rate preset in the control database represents the degree of influence of the unit value of the packet loss rate on the data transmission quality index. The control database stores the corresponding relationship between the unit value of the packet loss rate and its corresponding transmission quality impact index. For example, when the unit value of the packet loss rate is input into the control database, the control database can match the transmission quality impact index corresponding to the unit value of the packet loss rate; the transmission quality impact index corresponding to the unit value of the data transmission rate preset in the control database represents the degree of influence of the unit value of the data transmission rate on the data transmission quality index. The control database stores the corresponding relationship between the unit value of the data transmission rate and its corresponding transmission quality impact index. For example, when the unit value of the data transmission rate is input into the control database, the control database can match the transmission quality impact index corresponding to the unit value of the data transmission rate; the transmission quality impact index corresponding to the unit value of the transmission signal-to-noise ratio preset in the control database represents the degree of influence of the unit value of the transmission signal-to-noise ratio on the data transmission quality index. The control database stores the corresponding relationship between the unit value of the transmission signal-to-noise ratio and its corresponding transmission quality impact index. For example, when the unit value of the transmission signal-to-noise ratio is input into the control database, the control database can match the transmission quality impact index corresponding to the unit value of the transmission signal-to-noise ratio.

[0056] In this embodiment, when the real-time transmission delay duration is relatively large, even greater than the preset allowable transmission delay duration, it will lead to a decrease in the real-time performance of data transmission, resulting in a weakened timeliness of the exhaust gas detection data, affecting the accuracy of the detection results, and thus being unable to timely reflect the true situation of exhaust gas emissions; a low real-time data transmission rate will lead to low data transmission efficiency and slow data update, directly resulting in a decline in the data transmission quality index; a low real-time transmission signal-to-noise ratio means that the noise component in the signal is relatively high, reducing the clarity of data transmission, leading to an increase in the error rate of data transmission, and further reducing the data transmission quality index; a relatively large or small real-time transmission bandwidth utilization rate, that is, when the deviation from the preset reference utilization rate of the transmission bandwidth is relatively large, indicates that the utilization of network resources is not efficient enough or too crowded, which will lead to an increase in the instability of data transmission, further resulting in the loss or delay of exhaust gas detection data, and reducing the data transmission quality index; a high packet loss rate means that a large number of packets fail to be successfully transmitted during data transmission, resulting in inaccurate detection results, increasing the network burden and transmission time; therefore, through a detailed analysis of the data transmission quality index, problems in the data transmission process can be timely discovered and solved, which helps to ensure the accuracy and real-time performance of the exhaust gas detection data, thereby providing a reliable assessment of the exhaust gas emission situation.

[0057] Specifically, it is determined whether a warning prompt needs to be given for the process of exhaust gas detection data transmission according to the data transmission comparison result. The specific determination process is as follows: If the data transmission quality index is greater than or equal to the defined value of the data transmission quality index preset in the control database, the data transmission comparison result is recorded as the first transmission comparison result.

[0058] If the data transmission quality index is less than the defined value of the data transmission quality index preset in the control database, the data transmission comparison result is recorded as the second transmission comparison result.

[0059] If the data transmission comparison result is the second transmission comparison result, a warning prompt is directly given for the process of exhaust gas detection data transmission.

[0060] It should be noted that when the data transmission quality index is greater than or equal to the defined value of the data transmission quality index preset in the control database, it indicates that the quality of data transmission meets the requirements and there are no obvious quality problems. Therefore, this comparison result is recorded as the first transmission comparison result and no additional warning prompts are required. When the data transmission quality index is less than the defined value of the data transmission quality index preset in the control database, it indicates that the quality of data transmission is lower than the requirements and there may be problems such as data loss, delay, and error. Therefore, this comparison result is recorded as the second transmission comparison result. At this time, the warning prompt mechanism needs to be triggered. The specific warning prompt can be to pop up a specific text prompt box in the automatic control platform, such as "Please note that the quality index of the current exhaust gas detection data transmission has fallen below the defined value preset by the system, and some data may not have been successfully transmitted to the receiving end, resulting in incomplete data." The operator can take relevant measures according to the warning prompt to ensure the accuracy of data transmission, such as confirming whether the network connection is stable, whether there are interruptions or congestion phenomena, and adjusting the data transmission rate, packet size, etc. according to the current network environment. At the same time, the exhaust gas detection data is transmitted again.

[0061] Further, the process of obtaining the exhaust gas property data is as follows: The automatic control platform preprocesses the obtained exhaust gas detection data. The specific preprocessing includes data cleaning, data calibration, and data normalization, and the preprocessed exhaust gas detection data is recorded as the exhaust gas property data.

[0062] It should be noted that after obtaining the original exhaust gas detection data, data cleaning needs to be carried out first. Data cleaning mainly includes steps such as removing outliers, filling in missing values, and filtering noise. This process can effectively improve the accuracy and integrity of the data and ensure the reliability of subsequent analysis results. Data calibration refers to adjusting the data collected by the exhaust gas detection equipment to eliminate systematic errors and random errors. Through calibration, it can be ensured that the data collected by different equipment is comparable, thereby improving the accuracy of data analysis. Data normalization is to convert data with different dimensions or value ranges to a unified scale. Common normalization methods include maximum-minimum normalization, Z-score standardization, etc.

[0063] The exhaust gas property data specifically includes the real-time temperature, real-time moisture content, real-time nitrogen oxide concentration, real-time sulfur dioxide concentration, and real-time particulate matter concentration of the exhaust gas during the detection period.

[0064] It should be noted that the above real-time temperature usually measures the temperature data of the exhaust gas using an industrial temperature recorder (such as TP700, etc.). The moisture content can be measured by a relative humidity sensor. The real-time nitrogen oxide concentration can be measured by a dedicated nitrogen oxide monitoring device to monitor the nitrogen oxide concentration in the exhaust gas in real time. The real-time sulfur dioxide concentration can be measured by a sulfur dioxide sensor to obtain the sulfur dioxide concentration in the exhaust gas. The real-time particulate matter concentration uses a dedicated particulate matter monitoring device to monitor the particulate matter concentration in the exhaust gas in real time. In this embodiment, the detection period refers to the time interval for detecting the exhaust gas, and this period is usually determined according to the actual exhaust gas emission requirements.

[0065] In this embodiment, there are some mutual influence relationships among the real-time temperature, real-time moisture content, real-time nitrogen oxide concentration, real-time sulfur dioxide concentration, and real-time particulate matter concentration of the above exhaust gas during the detection period. Nitrogen oxides are the products of high-temperature combustion. Therefore, the higher the real-time temperature in the exhaust gas, the higher the nitrogen oxide concentration may be. The real-time temperature may also affect the generation of particulate matter. On the one hand, the fuel may burn more fully at high temperatures, reducing the generation of particulate matter. On the other hand, if the combustion conditions are poor, high temperatures may also lead to an increase in particulate matter such as unburned carbon particles. The evaporation of moisture absorbs heat, thereby reducing the temperature of the exhaust gas. The sulfur dioxide concentration will be further converted into sulfate particulate matter in the atmosphere, thereby affecting the particulate matter concentration.

[0066] Specifically, for the exhaust gas pollution index, the specific analysis process is as follows: The real-time nitrogen oxide concentration, real-time sulfur dioxide concentration, and real-time particulate matter concentration of the exhaust gas during the detection period are respectively processed by taking ratios with the preset nitrogen oxide reference concentration, sulfur dioxide reference concentration, and particulate matter reference concentration in the control database to obtain the real-time nitrogen oxide concentration ratio, real-time sulfur dioxide concentration ratio, and real-time particulate matter concentration ratio of the exhaust gas during the detection period.

[0067] The data transmission quality index, the real-time temperature, real-time moisture content, real-time nitrogen oxide concentration ratio, real-time sulfur dioxide concentration ratio, and real-time particulate matter concentration ratio of the exhaust gas during the detection period are comprehensively analyzed to obtain the exhaust gas pollution index. The specific analysis method is as follows: ; In the formula, is the exhaust gas pollution index, is the natural constant, is the start time point of the detection period, is the end time point of the detection period, is any time point within the detection period, , is the exhaust gas during the detection period is the real-time temperature at the time point. To control the reference temperature preset in the database, For the real-time moisture content of the tail gas at a time point within the detection period, To control the reference moisture content preset in the database, For the real-time nitrogen oxide concentration ratio of the tail gas at a time point within the detection period, To control the pollution impact factor corresponding to the unit value of the nitrogen oxide concentration ratio preset in the database, For the real-time sulfur dioxide concentration ratio of the tail gas at a time point within the detection period, To control the pollution impact factor corresponding to the unit value of the sulfur dioxide concentration ratio preset in the database, For the real-time particulate matter concentration ratio of the tail gas at a time point within the detection period, To control the pollution impact factor corresponding to the unit value of the particulate matter concentration ratio preset in the database, For the data transmission quality index, To control the pollution impact factor corresponding to the unit value of the data transmission quality index preset in the database.

[0068] It should be noted that any time point within the above detection period refers to any time point within the detection period, which can be the start, middle, or end, and any time point may be selected as the timing for recording data; the real-time temperature refers to the exhaust gas temperature at the current time point within the exhaust gas detection period; the reference temperature preset in the control database refers to a preset standard temperature value; the real-time moisture content refers to the content of moisture in the exhaust gas at the current time point; the reference moisture content preset in the control database refers to a preset standard moisture content value; the real-time nitrogen oxide concentration ratio refers to the ratio between the real-time nitrogen oxide concentration in the exhaust gas during the detection period and the nitrogen oxide reference concentration preset in the control database; the real-time sulfur dioxide concentration ratio refers to the ratio between the real-time sulfur dioxide concentration and the sulfur dioxide reference concentration; the real-time particulate matter concentration ratio refers to the ratio between the real-time particulate matter concentration and the particulate matter reference concentration; the pollution impact factor corresponding to the unit value of the nitrogen oxide concentration ratio preset in the control database represents the degree of influence of the unit value of the nitrogen oxide concentration ratio on the exhaust gas pollution index. The control database stores the corresponding relationship between the unit value of the nitrogen oxide concentration ratio and its corresponding pollution impact factor. For example, when the unit value of the nitrogen oxide concentration ratio is input into the control database, the control database can match the pollution impact factor corresponding to the unit value of the nitrogen oxide concentration ratio; the pollution impact factor corresponding to the unit value of the sulfur dioxide concentration ratio preset in the control database represents the degree of influence of the unit value of the sulfur dioxide concentration ratio on the exhaust gas pollution index. The control database stores the corresponding relationship between the unit value of the sulfur dioxide concentration ratio and its corresponding pollution impact factor. For example, when the unit value of the sulfur dioxide concentration ratio is input into the control database, the control database can match the pollution impact factor corresponding to the unit value of the sulfur dioxide concentration ratio; the pollution impact factor corresponding to the unit value of the particulate matter concentration ratio preset in the control database represents the degree of influence of the unit value of the particulate matter concentration ratio on the exhaust gas pollution index. The control database stores the corresponding relationship between the unit value of the particulate matter concentration ratio and its corresponding pollution impact factor. For example, when the unit value of the particulate matter concentration ratio is input into the control database, the control database can match the pollution impact factor corresponding to the unit value of the particulate matter concentration ratio.

[0069] In this embodiment, when the real-time temperature is too high or too low, that is, when the deviation from the preset reference temperature is large, it means that the combustion process is unstable, resulting in an increase in the content of harmful substances in the tail gas, thus pushing up the tail gas pollution index; when the real-time moisture content is too high or too low, that is, when the deviation from the preset reference moisture content is large, it will affect the chemical balance and physical state of the tail gas, leading to changes in the concentration of harmful substances in the tail gas, and further affecting the increase of the tail gas pollution index; a high real-time nitrogen oxide concentration ratio indicates that too much nitrogen oxide is generated during the combustion process, causing aggravated air pollution and at the same time pushing up the tail gas pollution index; a high real-time sulfur dioxide concentration ratio also indicates incomplete combustion or too high sulfur content in the fuel, resulting in the formation of acid rain and air pollution, and at the same time increasing the tail gas pollution index; a high real-time particulate matter concentration ratio indicates that a large amount of tiny particulate matter in the tail gas will cause serious air pollution and also increase the tail gas pollution index; a low data transmission quality index may lead to inaccurate or delayed real-time data, and the negative impacts include the inability to evaluate the tail gas pollution situation in a timely and accurate manner, resulting in the failure of emission control strategies, and further promoting the increase of the tail gas pollution index; therefore, through a detailed analysis of each parameter in the tail gas pollution index, tail gas emission problems can be discovered and diagnosed in a timely manner, which helps to optimize the combustion process, improve the tail gas treatment efficiency, reduce the emission of harmful substances. At the same time, more precise emission control strategies can be formulated to ensure that the tail gas emissions meet the environmental protection standards.

[0070] Specifically, it is determined whether to control the preset tail gas exhaust treatment method according to the tail gas pollution comparison result. The specific determination process is as follows: If the tail gas pollution index is greater than the tail gas pollution index threshold preset in the control database, the tail gas pollution comparison result is recorded as the first tail gas pollution comparison result, and the tail gas is exhaust-treated by the preset tail gas exhaust treatment method.

[0071] It should be explained that when the tail gas pollution index is greater than the tail gas pollution index threshold preset in the control database, it means that the pollutant concentration in the tail gas exceeds the tail gas pollution index threshold standard. In this case, it usually indicates that the preset tail gas exhaust treatment method cannot meet the current tail gas emission requirements.

[0072] If the tail gas pollution index is less than or equal to the tail gas pollution index threshold preset in the control database, the tail gas pollution comparison result is recorded as the second tail gas pollution comparison result, and the tail gas is exhaust-treated by the preset tail gas exhaust treatment method.

[0073] It should be explained that when the tail gas pollution index is less than or equal to the tail gas pollution index threshold preset in the control database, it means that the current tail gas can meet the preset environmental protection standards through the preset tail gas exhaust treatment method.

[0074] If the tail gas pollution comparison result is the first tail gas pollution comparison result, it is necessary to control the preset tail gas exhaust treatment method.

[0075] The control of the preset tail gas exhaust treatment method specifically includes increasing the treatment capacity of the tail gas treatment device and adding a tail gas purification link.

[0076] In this embodiment, when the tail gas pollution comparison result is the first tail gas pollution comparison result, that is, when the tail gas pollution index exceeds the preset tail gas pollution index threshold in the control database, control measures of increasing the treatment capacity of the tail gas treatment device and adding a tail gas purification link are taken. By increasing the treatment capacity of the tail gas treatment device, pollutants in the tail gas can be removed more effectively, ensuring that the tail gas emissions meet or are lower than the specified standards. At the same time, adding a tail gas purification link can further reduce the content of harmful substances in the tail gas and improve the purification effect.

[0077] Based on the result of controlling the preset tail gas exhaust treatment method, obtain and analyze the controlled tail gas property data to obtain a tail gas pollution control index. If the tail gas pollution control index is still greater than the preset tail gas pollution index threshold in the control database, directly give a warning prompt for the tail gas exhaust treatment method.

[0078] It should be explained that for the above control result of the preset tail gas exhaust treatment method, obtain and analyze the controlled tail gas property data to obtain a tail gas pollution control index. The controlled tail gas property data is the tail gas property data collected after implementing the control measures, and its data content is the same as the above-mentioned tail gas property data. Therefore, the analysis method corresponding to the tail gas pollution index obtained by analyzing the tail gas property data can be used to analyze the controlled tail gas property data to obtain a tail gas pollution control index; in this embodiment, the tail gas pollution control index obtained after controlling the preset tail gas exhaust treatment method is compared with the preset tail gas pollution index threshold in the control database again. If the tail gas pollution control index is still greater than the preset tail gas pollution index threshold in the control database, it means that even after taking control measures, the pollution degree of the tail gas emissions still exceeds the established environmental protection standards. This situation may indicate that the control measures are not effective enough, or there are relatively serious pollution problems in the tail gas emission source itself. Therefore, it is necessary to directly give a warning prompt for the tail gas exhaust treatment method. The specific warning prompt can directly remind the operator to pay attention to the pollution situation of the tail gas emissions by emitting an alarm sound.

[0079] Furthermore, the exhaust performance data specifically includes the real-time exhaust flow rate, average exhaust pressure, average nitrogen oxide concentration, average sulfur dioxide concentration, and average particulate matter concentration of the tail gas during the exhaust cycle.

[0080] It should be noted that the above real-time exhaust gas flow rate can be directly measured by installing a flow sensor in the exhaust system. The average exhaust gas pressure can be obtained by measuring it multiple times through a pressure sensor during the exhaust cycle and calculating the average value. The average nitrogen oxide concentration is obtained by using a chemical sensor to measure it multiple times during the exhaust cycle and averaging the measurement data. The measurement method of the average sulfur dioxide concentration is similar to that of nitrogen oxides, which is also obtained by using a chemical sensor to measure it multiple times during the exhaust cycle and averaging the measurement data. The measurement of the average particulate matter concentration usually uses a particulate matter sensor to measure it multiple times during the exhaust cycle and calculates the average value of the measured data to obtain the average particulate matter concentration. In this embodiment, the exhaust cycle refers to the time period for monitoring and evaluating the tail gas emissions, which is randomly set according to the specific tail gas emission situation.

[0081] Transmit the exhaust performance data to the automatic control platform. Based on the process of transmitting the exhaust performance data, obtain the exhaust data transmission parameters and analyze the exhaust data transmission quality index.

[0082] It should be noted that the process of transmitting the above exhaust performance data is the same as the process of transmitting the above tail gas detection data. Based on the process of transmitting the exhaust performance data, the obtained exhaust data transmission parameters are also the same as the above data transmission parameters. The analysis method corresponding to the data transmission quality index obtained by analyzing the data transmission parameters can also be used to analyze the exhaust data transmission quality index.

[0083] Specifically, the specific analysis process of the exhaust performance index is as follows: Perform a difference operation on the real-time exhaust gas flow rate of the tail gas during the exhaust cycle and the preset exhaust reference flow rate in the control database to obtain the real-time exhaust gas flow rate deviation value of the tail gas during the exhaust cycle.

[0084] Perform a difference operation on the average exhaust gas pressure of the tail gas during the exhaust cycle and the preset exhaust reference pressure in the control database to obtain the exhaust gas pressure deviation value of the tail gas during the exhaust cycle.

[0085] Comprehensively analyze the exhaust data transmission quality index, the real-time exhaust gas flow rate deviation value of the tail gas during the exhaust cycle, the exhaust gas pressure deviation value, the average nitrogen oxide concentration, the average sulfur dioxide concentration, and the average particulate matter concentration to obtain the exhaust performance index.

[0086] In this embodiment, there is an interaction relationship among parameters such as the real-time exhaust gas flow deviation value, exhaust gas pressure deviation value, average nitrogen oxide concentration, average sulfur dioxide concentration, and average particulate matter concentration during the exhaust period. When the exhaust gas flow is too large, it may cause the exhaust gas pressure to drop. When the exhaust gas flow increases, the pollutant emissions in the exhaust gas may also increase accordingly. The decrease in exhaust gas pressure is conducive to the diffusion and dilution of pollutants, thereby reducing the emission concentration. When the exhaust gas pressure is too low, it will cause poor exhaust gas discharge and instead increase the pollutant emission concentration. Some chemical reactions in exhaust gas purification may simultaneously involve the conversion of pollutants such as nitrogen oxides, sulfur dioxide, and particulate matter. For example, some catalysts can simultaneously reduce the emission concentrations of nitrogen oxides and particulate matter. The particulate matter in the exhaust gas may adsorb or condense other pollutants, such as sulfur dioxide and nitrogen oxides, thereby changing their emission concentrations. It should be noted that the exhaust data transmission quality index is an important parameter for measuring the accuracy and reliability of exhaust data. In exhaust performance analysis, accurate and reliable exhaust data is the basis for drawing correct conclusions. If the exhaust data transmission quality is poor, it may lead to data distortion and increased errors, thereby affecting the accuracy and reliability of exhaust performance analysis. Therefore, by considering the exhaust data transmission quality index, the accuracy and reliability of exhaust data can be ensured, thereby improving the accuracy and reliability of exhaust performance analysis, reducing data errors and distortion, and more accurately reflecting the performance and state of the exhaust system.

[0087] The specific analysis method for the exhaust performance index is as follows: ; In the formula, is the exhaust performance index, is the natural constant, is the start time point of the exhaust period, is the end time point of the exhaust period, is any time point during the exhaust period, , is the exhaust data transmission quality index, is the exhaust performance influence index corresponding to the unit value of the exhaust data transmission quality index preset in the control database, is the exhaust gas during the exhaust period the real-time exhaust gas flow deviation value at the time point, is the allowable exhaust gas flow deviation value preset in the control database, is the exhaust gas pressure deviation value of the exhaust gas during the exhaust period, is the allowable exhaust gas pressure deviation value preset in the control database, is the average nitrogen oxide concentration of the exhaust gas during the exhaust period, is the allowable nitrogen oxide concentration preset in the control database, is the average sulfur dioxide concentration of the tail gas during the exhaust cycle, is the allowable sulfur dioxide concentration preset in the control database, is the average particulate matter concentration of the tail gas during the exhaust cycle, is the allowable particulate matter concentration preset in the control database.

[0088] It should be noted that any time point during the above exhaust cycle refers to any instant during the exhaust cycle, which can be the start, end, or any moment in the middle; the real-time exhaust flow deviation value refers to the difference between the real-time exhaust flow of the tail gas during the exhaust cycle and the exhaust reference flow preset in the control database; the allowable exhaust flow deviation value preset in the control database refers to the maximum difference between the allowable exhaust flow and the exhaust reference flow under normal operating conditions; the exhaust pressure deviation value refers to the difference between the average exhaust pressure of the tail gas during the exhaust cycle and the exhaust reference pressure preset in the control database; the allowable exhaust pressure deviation value preset in the control database refers to the maximum difference between the allowable exhaust pressure and the exhaust reference pressure under normal operating conditions; the average nitrogen oxide concentration refers to the average value of the measured nitrogen oxide concentration during the exhaust cycle; the allowable nitrogen oxide concentration preset in the control database refers to the maximum allowable value of the nitrogen oxide concentration in the tail gas under normal operating conditions; the average sulfur dioxide concentration refers to the average value of the measured sulfur dioxide concentration during the exhaust cycle; the allowable sulfur dioxide concentration preset in the control database refers to the maximum allowable value of the sulfur dioxide concentration in the tail gas under normal operating conditions; the average particulate matter concentration refers to the average value of the measured particulate matter concentration during the exhaust cycle; the allowable particulate matter concentration preset in the control database refers to the maximum allowable value of the particulate matter concentration in the tail gas under normal operating conditions; the exhaust performance impact index corresponding to the unit value of the exhaust data transmission quality index preset in the control database indicates the degree of influence of the unit value of the exhaust data transmission quality index on the exhaust performance index. The control database stores the corresponding relationship between the unit value of the exhaust data transmission quality index and its corresponding exhaust performance impact index. For example, when the unit value of the exhaust data transmission quality index is input into the control database, the control database can match the exhaust performance impact index corresponding to the unit value of the exhaust data transmission quality index.

[0089] In this embodiment, a lower exhaust gas data transmission quality index will result in inaccurate or incomplete exhaust gas data, thus affecting the accurate evaluation of exhaust gas performance; when the exhaust gas flow deviation value is large, even greater than the preset allowable exhaust gas flow deviation value, it will directly lead to poor exhaust gas flow or excessive emissions, causing a decline in the exhaust gas performance index; when the exhaust gas pressure deviation value is large, even greater than the preset allowable exhaust gas pressure deviation value, it indicates that there may be blockage or leakage during the exhaust gas process, resulting in a reduction in the exhaust gas performance index; when the average nitrogen oxide concentration is high, even higher than the preset allowable nitrogen oxide concentration, it indicates incomplete combustion or too high combustion temperature, resulting in a reduction in the exhaust gas performance index; when the average sulfur dioxide concentration is high, even higher than the preset allowable sulfur dioxide concentration, it also indicates incomplete combustion or too high sulfur content in the fuel, directly leading to a reduction in the exhaust gas performance index; when the average particulate matter concentration is high, even higher than the preset allowable particulate matter concentration, it indicates incomplete combustion of the exhaust gas or poor exhaust gas filtration effect, resulting in a reduction in the exhaust gas performance index; therefore, by analyzing the parameters in the exhaust gas performance index in detail, problems in the exhaust gas process can be discovered and diagnosed in a timely manner, which helps to take maintenance measures in advance to prevent the problems from deteriorating and ensure the normal operation of the exhaust gas function.

[0090] Specifically, it is finally determined whether a warning prompt needs to be issued for the exhaust gas treatment according to the exhaust gas performance comparison result. The specific determination process is as follows: If the exhaust gas performance index is greater than or equal to the preset exhaust gas performance index boundary value in the control database, the exhaust gas performance comparison result is recorded as the first exhaust gas performance comparison result.

[0091] If the exhaust gas performance index is less than the preset exhaust gas performance index boundary value in the control database, the exhaust gas performance comparison result is recorded as the second exhaust gas performance comparison result.

[0092] If the exhaust gas performance comparison result is the second exhaust gas performance comparison result, a warning prompt needs to be issued for the exhaust gas treatment.

[0093] In this embodiment, the exhaust performance index is compared with the predefined exhaust performance index threshold value in the control database. When the exhaust performance index is greater than or equal to the predefined exhaust performance index threshold value in the control database, it means that the performance of the tail gas emission has reached or exceeded the predefined standard, and it is considered to meet or be better than the expected emission performance. Therefore, the exhaust performance comparison result is recorded as the first exhaust performance comparison result, indicating that the emission performance is good or meets the standard. When the exhaust performance index is less than the predefined exhaust performance index threshold value in the control database, it means that the performance of the tail gas emission is lower than the predefined standard, which may indicate problems with the equipment, poor fuel quality, or the need to adjust the emission control strategy. Therefore, the exhaust performance comparison result is recorded as the second exhaust performance comparison result, indicating that the emission performance does not meet the standard or there are potential problems. If the exhaust performance comparison result is the second exhaust performance comparison result, that is, the emission performance does not meet the standard or there are potential problems, a warning prompt needs to be issued for the tail gas exhaust treatment. The specific warning prompt can display reminder text on the automatic control platform, such as "Warning: The tail gas emission performance does not meet the standard. Please check whether the exhaust pipe is blocked or leaking!".

[0094] Referring to Figure 2 As shown, the second aspect of the present invention provides a method, including: S1. Data transmission detection: Detect the tail gas data obtained during the exhaust operation stage to obtain tail gas detection data, and transmit it to the automatic control platform.

[0095] S2. Tail gas detection: The automatic control platform preprocesses the obtained tail gas detection data, records the preprocessed tail gas detection data as tail gas property data, and analyzes to obtain the tail gas pollution index, compares it with the predefined tail gas pollution index threshold value in the control database to obtain the tail gas pollution comparison result, and determines whether it is necessary to control the predefined tail gas exhaust treatment method according to the tail gas pollution comparison result.

[0096] S3. Tail gas exhaust detection: Detect and obtain the exhaust performance data during the tail gas exhaust treatment process, analyze to obtain the exhaust performance index, and compare it with the predefined exhaust performance index threshold value in the control database to obtain the exhaust performance comparison result, and finally determine whether a warning prompt needs to be issued for the tail gas exhaust treatment according to the exhaust performance comparison result.
