Abstract
Description
Technical Field
[0001] This invention relates to the field of industrial waste gas treatment and environmental monitoring technology, and in particular to a method and system for intelligent monitoring and early warning of VOCs incinerator operating conditions based on reinforcement learning and ant colony algorithm. Background Technology
[0002] Volatile organic compound (VOCs) incinerators are crucial equipment for industrial waste gas treatment, widely used in industries such as chemical, pharmaceutical, coating, and electronics manufacturing. Their operational stability and treatment effectiveness directly impact pollutant emission compliance and production safety. Existing VOCs incinerators typically monitor basic operations through parameters such as combustion chamber temperature, pressure, and inlet / outlet concentrations, triggering alarms when these parameters exceed limits to prompt maintenance personnel for intervention. However, these methods generally suffer from the following shortcomings: First, existing monitoring methods mostly rely on fixed thresholds or single-parameter alarm mechanisms, which have limited adaptability to fluctuations in operating conditions, load changes, and seasonal differences. They are prone to false alarms under normal fluctuation conditions or missed alarms in complex scenarios such as hidden degradation and bypassing, making it difficult to identify potential violations or abnormal operating states in a timely manner. Second, existing systems mostly process multi-source operating data at the level of "real-time display or simple storage," lacking systematic analysis of the inherent logical consistency between data, making it difficult to determine whether the incinerator is in a truly effective governance state from the perspective of the overall operating mechanism.
[0003] Therefore, we propose an intelligent monitoring and early warning method and system for the operating conditions of VOCs incinerators. The information disclosed in the background section is only for enhancing the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a method and system for intelligent monitoring and early warning of VOCs incinerator operating conditions, thereby solving the technical problems mentioned in the background section.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A method for intelligent monitoring and early warning of VOCs incinerator operating conditions includes the following steps: S1. The edge monitoring node collects operating condition data from the VOCs incinerator operating system in real time. The operating condition data includes at least: incinerator combustion chamber temperature data, system pressure data, inlet and outlet VOCs concentration data, operating status data of key actuators and bypass valve status data. A unified timestamp is added to the collected operating condition data to form a time-ordered original operating condition data stream. S2. In the original operating condition data stream, select key operating data that reflects the effectiveness of VOCs incinerator pollution control and operational compliance, and generate data integrity identification information for the key operating data in chronological order, so that the key operating data at each moment and its corresponding data integrity identification information form a one-to-one correspondence. S3. Based on key operational data and its corresponding data integrity identification information, construct a continuous and related anti-tampering evidence chain in chronological order, so that the key operational data at the current moment and the key operational data at the previous moment form an irreversible logical relationship, thereby achieving anti-tampering protection for the continuity of key operational data. S4. Utilize the tamper-proof evidence chain to verify the consistency of key operating data. By analyzing the logical consistency between inlet and outlet VOCs concentration data, bypass valve status data, and operating status data of key actuators, identify abnormal operating states that are inconsistent with the normal operating mechanism and determine the abnormal operating states as potential violations or abnormal working conditions. S5. When an abnormal operating state is detected, the abnormal operating condition evidence solidification process is triggered. The tamper-proof evidence chain fragment corresponding to the abnormal operating state is encrypted, encapsulated, and stored as abnormal operating condition evidence data. At the same time, the corresponding level of operating condition warning information is generated according to the degree of abnormality. S6. Output the operating condition warning information locally and report it remotely. During the reporting process, upload the integrity verification information of the abnormal operating condition evidence data simultaneously, so that the receiving end can perform consistency verification and traceability review of the operating condition warning information and its corresponding abnormal operating condition evidence data.
[0006] S1 specifically involves: establishing data acquisition connections with the incinerator control system and field sensors through edge monitoring nodes deployed at the VOCs incinerator site to acquire operational condition data acquisition channels reflecting the incinerator's operating status; collecting in real-time data from the operational condition data acquisition channels, including incinerator combustion chamber temperature, system pressure, inlet and outlet VOCs concentration, operational status data of key actuators, and bypass valve status data, according to a unified sampling period, to form raw operational condition data; assigning a timestamp to each raw operational condition data point under a unified time reference to ensure sequential consistency of the raw operational condition data in the time dimension; and combining the raw operational condition data with the added timestamps into a time-ordered raw operational condition data stream according to the acquisition time sequence, which serves as input data for subsequent key operational data filtering.
[0007] S2 specifically involves: based on the pollution control mechanism of VOCs incinerators, selecting key operational data from the original operating condition data stream to characterize the compliance and effectiveness of incinerator operation; key operational data includes at least inlet and outlet VOCs concentration data directly related to pollutant removal, bypass valve status data directly related to the operating status of the treatment facilities, and combustion chamber temperature data related to the combustion process; for each selected key operational data, generating data integrity identification information according to its corresponding timestamp, so that the key operational data and data integrity identification information form a one-to-one correspondence; and outputting the key operational data and its data integrity identification information that form a correspondence as the basic data unit for constructing an anti-tampering evidence chain.
[0008] S3 specifically involves: arranging the basic data units sequentially according to timestamp order to determine the temporal relationship between key operational data at adjacent times; associating the key operational data at the current time and its data integrity identifier with the integrity identifier of the key operational data at the previous time to generate a continuous association relationship; based on the continuous association relationship, constructing an anti-tampering evidence chain covering a continuous time period, so that the key operational data form an irreversible time sequence association in logical structure; and using the constructed anti-tampering evidence chain as a trusted data foundation for subsequent operational consistency verification and anomaly identification.
[0009] S4 specifically involves: based on an anti-tampering evidence chain, performing operational consistency verification on key operational data over a continuous time period, and analyzing the logical relationships between inlet and outlet VOCs concentration data, bypass valve status data, and key actuator operational status data; during the operational consistency verification process, an ant colony algorithm is introduced to construct a multi-path consistency evaluation model, which comprehensively evaluates the consistency matching degree of the current key operational data under different paths by simulating various possible normal operation paths; combined with a reinforcement learning mechanism, the parameters of the consistency evaluation model are adaptively updated, enabling the model to continuously strengthen its ability to identify normal operation modes based on historical operational results; when the matching degree of the current key operational data in the consistency evaluation model is continuously lower than the preset consistency threshold, the corresponding operational status is identified as an abnormal operational status, and an abnormal operational status identifier is output.
[0010] S5 specifically involves: upon identifying an abnormal operating state, triggering the abnormal operating condition evidence solidification process; extracting evidence chain fragments corresponding to the abnormal operating state from the tamper-proof evidence chain; encrypting and encapsulating the evidence chain fragments to form abnormal operating condition evidence data; storing the abnormal operating condition evidence data in the protected storage area of the edge monitoring node; determining the warning level of the abnormal operating state based on its duration, frequency, and consistency deviation, combined with the risk assessment results obtained from reinforcement learning; generating operating condition warning information corresponding to the warning level; and associating and marking the operating condition warning information with the abnormal operating condition evidence data.
[0011] Specifically, S6 involves: outputting operational condition warning information locally at the VOCs incinerator site in a visual manner to alert on-site maintenance personnel to the current abnormal operating status; sending operational condition warning information to a remote monitoring or management platform via remote communication; simultaneously uploading integrity verification information of associated abnormal operating condition evidence data to support remote verification of the authenticity of the abnormal operating condition evidence data; and enabling the remote receiving end to perform consistency verification and traceability review of the operational condition warning information and its corresponding abnormal operating condition evidence data based on the integrity verification information, thus forming a complete closed loop of warning and evidence collection.
[0012] A VOCs incinerator operating condition intelligent monitoring and early warning system includes: Edge monitoring nodes are deployed at the VOCs incinerator site to establish data acquisition connections with the incinerator control system and on-site sensors, and are configured with multiple operating condition data acquisition channels. The key operational data processing module, located in the edge monitoring node, is used to filter key operational data that characterizes the effectiveness of VOCs incinerator treatment and operational compliance from the time-ordered raw operational data stream; The data integrity identifier generation module is set in the edge monitoring node and is used to generate data integrity identifier information that corresponds to each key running data frame. The tamper-proof evidence chain construction module is set in the edge monitoring node and is used to perform sequential consistency verification on key operational data frames at consecutive times based on the timestamp field and sequence number field of key operational data frames. The consistency assessment and anomaly identification module is set up in the edge monitoring node to construct a feature vector reflecting the consistency of the operating mechanism, provided that the consistency verification of the anti-tampering evidence chain is passed. The abnormal operating condition evidence solidification and early warning generation module is set in the edge monitoring node. It is used to extract evidence chain fragments containing data before and after the occurrence of the abnormal operating state from the anti-tamper evidence chain when an abnormal operating state is identified. The early warning output and remote reporting module is set in the edge monitoring node and is used to output local early warning information at the VOCs incinerator site, including abnormal event identifier, early warning level, risk score and evidence time range; The remote consistency verification module is set up in a remote monitoring or management platform to establish a one-to-one correspondence between early warning information and abnormal operating condition evidence data based on abnormal event identifiers and evidence package summaries.
[0013] The beneficial effects of this invention are as follows: This invention aligns the sampling periods and timestamps multi-source operational data to form a time-ordered operational data stream, effectively avoiding misjudgments caused by asynchronous multi-source data. This ensures the comparability and analytical accuracy of different parameters at the same time scale, providing a reliable foundation for subsequent consistency assessments. By generating data integrity identifiers for key operational data and constructing a chain-like summary of tamper-proof evidence, any operational data at any given time is irreversibly linked to preceding and following data. Any data tampering can be detected, thus achieving integrity protection and traceability verification of operational data, significantly enhancing regulatory evidence collection and accountability capabilities.
[0014] This invention constructs a consistency feature vector encompassing inlet and outlet VOCs concentrations, purification efficiency, bypass valve status, combustion chamber temperature, and actuator status, and calculates the consistency deviation. This allows for a holistic assessment of the incinerator's operating status from an operational mechanism perspective, identifying hidden anomalies where individual parameters have not exceeded limits but the overall system has deviated from normal operating conditions. The invention utilizes an ant colony algorithm for multi-path consistency evaluation on the operating mode diagram, avoiding the limitations of single rules or fixed models. Furthermore, reinforcement learning is combined to adaptively update the consistency evaluation parameters, enabling the system to continuously optimize early warning criteria under different loads, operating conditions, and long-term operation, thereby reducing false alarm rates and improving the stability of anomaly identification.
[0015] This invention achieves real-time solidification of abnormal data by simultaneously capturing fragments of the evidence chain before and after the anomaly occurs and constructing encrypted abnormal operating condition evidence data packets when identifying abnormal operating states. Simultaneously, it generates tiered early warning information based on risk scores, enabling maintenance personnel and regulatory departments to take differentiated measures according to risk levels, thus improving emergency response and management efficiency. By binding early warning information to abnormal operating condition evidence data one-to-one and employing a hierarchical reporting, receipt confirmation, and remote consistency recalculation verification mechanism, data is guaranteed not to be lost or confused even under network fluctuations or interruptions. This achieves a complete closed loop of operating condition early warning and evidence review, enhancing the system's reliability and practicality in real-world industrial environments.

Detailed Implementation
[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Example 1: As Figure 1 As shown in the figure, this embodiment provides a method for intelligent monitoring and early warning of the operating conditions of a VOCs incinerator, including the following steps: S1. Operational condition data acquisition steps: The edge monitoring node collects operational condition data in real time from the VOCs incinerator's operating system. The operational condition data includes at least: incinerator combustion chamber temperature data, system pressure data, inlet and outlet VOCs concentration data, operating status data of key actuators, and bypass valve status data. A unified timestamp is added to the collected operational condition data to form a time-ordered original operational condition data stream. S2. Key Operational Data Screening and Integrity Identification Steps: In the original operational data stream, select key operational data that reflects the effectiveness of VOCs incinerator pollution control and operational compliance, and generate data integrity identification information for the key operational data in chronological order, so that the key operational data at each moment and its corresponding data integrity identification information form a one-to-one correspondence. S3. Steps for constructing an anti-tampering evidence chain: Based on key operational data and its corresponding data integrity identification information, construct a continuous and related anti-tampering evidence chain in chronological order, so that the key operational data at the current moment and the key operational data at the previous moment form an irreversible logical relationship, thereby achieving anti-tampering protection for the continuity of key operational data. S4. Operational Consistency Verification and Anomaly Identification Steps: Using the anti-tampering evidence chain, the operational consistency of key operational data is verified. By analyzing the logical consistency relationship between inlet and outlet VOCs concentration data, bypass valve status data, and operational status data of key actuators, abnormal operational states that are inconsistent with the normal operation mechanism are identified, and the abnormal operational states are judged as potential violations or abnormal working conditions. S5. Abnormal operating condition evidence solidification and graded early warning steps: When an abnormal operating state is identified, the abnormal operating condition evidence solidification process is triggered. The tamper-proof evidence chain fragments corresponding to the abnormal operating state are encrypted, encapsulated, and stored as abnormal operating condition evidence data. At the same time, operating condition early warning information of the corresponding level is generated according to the degree of abnormality. S6. Early warning output and traceable reporting steps: Output the operating condition early warning information locally and report it remotely. During the reporting process, upload the integrity verification information of the abnormal operating condition evidence data simultaneously, so that the receiving end can perform consistency verification and traceability review on the operating condition early warning information and its corresponding abnormal operating condition evidence data.
[0019] S1 specifically includes the following sub-steps: S110. Steps for establishing and mapping operating condition data acquisition channels: By deploying edge monitoring nodes at the VOCs incinerator site, data acquisition connections are established with the incinerator control system and field sensors to form operating condition data acquisition channels for acquiring operating condition data. The operating condition data acquisition channels include at least temperature acquisition channels, pressure acquisition channels, concentration acquisition channels, status acquisition channels, and valve position acquisition channels. Among them, the edge monitoring nodes configure corresponding operating condition data acquisition channels for each type of operating condition data and establish channel-data item mapping relationships so that each operating condition data acquisition channel can uniquely correspond to its output data type and data item name. The data acquisition connection can adopt any one or more of the following implementation methods: fieldbus, industrial Ethernet, serial communication, or analog acquisition modules, to ensure that the edge monitoring nodes can stably acquire the data sources required for subsequent acquisition.
[0020] S120. Unified Sampling Period Acquisition and Time Grid Alignment Steps: Based on the channel-data item mapping relationship, the edge monitoring node performs polling or synchronous sampling of the operating condition data acquisition channels according to the unified sampling period, acquiring and forming raw operating condition data in real time. The raw operating condition data includes at least: incinerator combustion chamber temperature data, system pressure data, inlet and outlet VOCs concentration data, operating status data of key actuators, and bypass valve status data. When different operating condition data acquisition channels have asynchronous outputs, the edge monitoring node aligns the asynchronously output data to a unified time grid. The unified time grid satisfies the following: in, To standardize the sampling period, To align the start time, For the first Each aligned sampling time, It is a non-negative integer; by aligning the original operating condition data to a unified time grid, the data processed in subsequent steps remains comparable and consistent on the time scale.
[0021] S130, Unified Time Base Timestamp Generation and Synchronization Error Constraint Steps: The edge monitoring node generates timestamp information for each piece of original operating condition data based on the unified time base, and binds the timestamp information with the corresponding original operating condition data; the edge monitoring node performs periodic time synchronization with the unified time base to suppress clock drift, ensuring that the synchronization error of the timestamp information relative to the unified time base meets the following requirements: in, For synchronization error, The maximum allowable synchronization error threshold is set; by constraining the synchronization error, the original operating condition data is made consistent and traceable in the time dimension; in an optional implementation, periodic time synchronization can be achieved through network time synchronization or satellite time synchronization to further improve the stability of the unified time reference.
[0022] S140, Standard Data Frame Encapsulation, Quality Flag Marking, and Ordered Buffer Output Steps: The edge monitoring node encapsulates the raw operating condition data with added timestamp information into a standard data frame. The standard data frame includes at least a timestamp field, a data type field, a data value field, a data unit field, and a data quality flag field. The data quality flag field is used to indicate abnormal sampling states such as over-range, missing, and jump. The edge monitoring node writes the standard data frame into a time-ordered buffer queue according to the timestamp information and outputs it in chronological order to form a time-ordered raw operating condition data stream. When missing or abnormal sampling occurs, the edge monitoring node marks the corresponding standard data frame according to the data quality flag field, thereby ensuring the availability and interpretability of the input data for subsequent key operating data filtering steps.
[0023] S2 specifically includes the following sub-steps: S210, Determination and Extraction of the Minimum Set of Key Operating Data: The edge monitoring node takes the time-ordered raw operating condition data stream output by S140 as input. Based on the requirements for judging the effectiveness of VOCs incinerator pollution control and operational compliance, it determines and extracts key operating data from the time-ordered raw operating condition data stream. The key operating data is the minimum data set used to characterize the effectiveness and compliance of the control. The minimum data set includes at least: inlet VOCs concentration data, outlet VOCs concentration data, bypass valve status data, combustion chamber temperature data, and operating status data of key actuators. Among them, each data item uses the data value field and data unit field of the standard data frame to ensure that the same data item has a consistent unit caliber at different sampling times, and to enable subsequent steps to perform comparable analysis on the same data item.
[0024] S220, Key Operational Data Frame Encapsulation and Purification Efficiency Derived Data Calculation Steps: Following the same encapsulation rules as S140, the edge monitoring node encapsulates the key operational data corresponding to each aligned sampling time into a key operational data frame. The key operational data frame includes at least: a timestamp field, a data type field, a data value field, a data unit field, a data quality flag field, and a sequence number field. The sequence number field indicates the position of the key operational data frame in the time series. Based on this, the edge monitoring node calculates the purification efficiency data based on the influent VOCs concentration data and effluent VOCs concentration data within the same key operational data frame. It satisfies: in, For the first VOCs concentration data at each aligned sampling time point For the first VOCs concentration data at each aligned sampling time point To prevent the minimum concentration lower limit constant from having a denominator of zero, For the first Purification efficiency data at each aligned sampling time; To maximize the function; the purification efficiency data is written into the key operation data frame as a derived data item of the key operation data, and is associated with the bypass valve status data, combustion chamber temperature data and the operation status data of the key actuators at the same time with a timestamp consistent relationship.
[0025] S230. Data Integrity Identifier Generation Steps: The edge monitoring node generates a one-to-one data integrity identifier for each critical operational data frame. The data integrity identifier is a hash digest obtained by performing digest calculation on the critical operational data frame. The hash digest satisfies: in, For the preset hash function, For the first The key running data frames at each aligned sampling moment; For hash digest; Sampling sequence number; key running data frame The hash digest is obtained by concatenating at least the timestamp field, data type field, data value field, data unit field, data quality flag field, and sequence number field in a preset order. With critical runtime data frames This establishes a one-to-one correspondence and enables key operational data frames at different sampling times to be uniquely located through the sequence number field and the timestamp field.
[0026] S240, Key Operational Data and Integrity Identifier Output and Abnormal Continuity Assurance Steps: The edge monitoring node outputs each key operational data frame with its corresponding hash digest. The binding process creates a one-to-one correspondence between "critical runtime data frame - data integrity identification information" output unit, which is then continuously output in timestamp order to subsequent steps in constructing the anti-tampering evidence chain. When the data quality flag field of the critical runtime data frame indicates a missing, abrupt, or out-of-range condition, the edge monitoring node still generates a hash digest corresponding to that moment. Furthermore, the data quality flag field and placeholder data values are retained in the critical runtime data frames to ensure the accuracy of the critical runtime data frames and their corresponding hash digests. Continuous output in time series prevents subsequent steps in building the anti-tampering evidence chain from being broken due to data gaps, thereby improving the integrity and traceability of the evidence chain construction.
[0027] S3 specifically includes the following sub-steps: S310, Key Operational Data Frame Sequence Consistency Verification and Evidence Chain Segmentation Determination Steps: The edge monitoring node takes the "Key Operational Data Frame - Data Integrity Identification Information" output from S240 as input, determines the temporal sequence relationship between adjacent key operational data frames according to the sequence number field and timestamp field of the key operational data frame, and performs a sequence consistency verification to ensure that the sequence number field monotonically increases and the timestamp field does not go backward; when a discontinuous sequence number, a backward timestamp, or a timestamp interval between adjacent key operational data frames is detected, the node will perform a sequence consistency verification. At that time, the edge monitoring node will determine the current key running data frame as the starting point of the new evidence chain segment and generate new chain segment header information to ensure the continuity and verifiability of the subsequent anti-tampering evidence chain in the time dimension.
[0028] S320, Chained Digest Association Calculation and Continuous Association Generation Steps: Edge monitoring nodes generate hash digests based on S230. Correlation calculations are performed between key operational data at adjacent time points to generate a chain-like summary representing continuous correlations. Chained summary By hashing the current time Chained summary from the previous time step By concatenating and summarizing again, the chained summary is obtained, which satisfies the following: in, For the preset hash function, This indicates a concatenation operation performed in a preset order. This refers to the timestamp information corresponding to the timestamp field in the critical runtime data frame. This refers to the sampling sequence number corresponding to the sequence number field in the key running data frame; through chained summaries Also depends on the hash digest at the current time. Chained summary from the previous time step This ensures that any change in key operational data at any given time will affect subsequent chained summaries, thus achieving an irreversible continuous association.
[0029] S330, Segment Start Chain Summary Generation and Segment Header Information Construction Steps: For the initial key running data frame of each evidence chain segment, the edge monitoring node generates a random start amount for the chain segment. And based on the hash digest corresponding to the starting key running data frame. Random starting quantity of chain segment Generate a starting chained digest The initial chained digest satisfies: in, This is the random starting value for the chain segment; A hash digest of the critical running data frame at the beginning of the chain segment; This is a chained digest starting with a segment; the random starting amount for the segment. With the starting chain summary Together, they constitute the head information of the evidence segment and, together with the subsequent chain summary of that evidence segment, form the chain header information. Maintain associated storage to ensure that each piece of evidence has a verifiable starting point and that the summary calculation caliber is consistent with the continuous associations generated by S320.
[0030] S340. The steps for solidifying, outputting, and verifying the consistency of the tamper-proof evidence chain node structure are as follows: The edge monitoring node binds the chained digests generated in chronological order with the corresponding key operational data frames, constructing a tamper-proof evidence chain formed by connecting multiple evidence chain nodes in chronological order; wherein each evidence chain node includes at least one key operational data frame. Corresponding hash digest Corresponding chained summary and chained summaries for characterizing forward associations When outputting a tamper-proof evidence chain, the edge monitoring node must output at least the key runtime data frame. Hash digest With chained summaries It supports traceable verification according to the following consistency verification rules: based on key runtime data frames. Recalculate the hash digest and compare it with the output hash digest. Compare, and then use hash digest Chained summary from the previous time step Recalculate to obtain the chain digest and compare it with the output chain digest. Comparison; when any comparison is inconsistent, it is determined that the corresponding evidence chain node or its forward associated node is at risk of being tampered with, thereby achieving tamper-proof protection and traceability verification of the continuity of key operational data.

With purification efficiency data The combined features are used to define the actions used to adjust the consistency evaluation parameters as reinforcement learning actions. Edge monitoring nodes generate rewards based on the early warning output and post-verification results. False positives and false negatives correspond to negative rewards, while correct identification corresponds to positive rewards; edge monitoring nodes update the action value function according to the Q-learning update rule. : in, For learning rate, The discount factor is used; through reinforcement learning updates, the consistency assessment parameters adaptively converge under different seasonal loads and VOCs fluctuation conditions, thereby reducing false alarms and improving the ability to identify hidden abnormal operating states. This represents a candidate action in the action space.
[0034] S440. Consistency matching degree calculation and anti-jitter abnormal operation status judgment steps: The edge monitoring node will select the optimal consistency path. Path cost Mapped to consistency matching degree The consistency matching degree satisfies: in, A larger value indicates a higher degree of matching between the current critical operational data and the normal operational path; edge monitoring nodes set matching degree thresholds. And set the sliding window length Number of consecutive judgments When the sliding window length Next continuum Each sliding window satisfies When the corresponding operating status is identified as an abnormal operating status, an abnormal operating status identifier is output, so that the abnormal operating status determination has anti-jitter capability and avoids false alarms caused by single-point noise.

Multiple operational data acquisition channels are configured to collect real-time data on incinerator combustion chamber temperature, system pressure, inlet and outlet VOCs concentrations, operational status of key actuators, and bypass valve status. Edge monitoring nodes also perform time-aligned processing on the collected operational data according to a unified sampling period, generating a time-ordered raw operational data stream with an appended unified timestamp. The critical operation data processing module is located in the edge monitoring node. It is used to filter key operation data that characterize the effectiveness of VOCs incinerator treatment and operation compliance from the time-ordered raw operation data stream, and encapsulate the key operation data into key operation data frames. The critical operation data processing module is also used to calculate purification efficiency data based on inlet and outlet VOCs concentration data, and write the purification efficiency data as derived data items into the corresponding key operation data frames. The data integrity identifier generation module is set in the edge monitoring node. It is used to generate data integrity identifier information that corresponds to each key running data frame and to bind the key running data frame with the data integrity identifier information for output. The tamper-proof evidence chain construction module is set in the edge monitoring node. It is used to perform sequential consistency verification on key running data frames at consecutive times based on the timestamp field and sequence number field of key running data frames, and generate a chain digest based on the data integrity identification information at the current time and the chain digest at the previous time, thereby constructing an tamper-proof evidence chain formed by connecting multiple evidence chain nodes in chronological order.

The module also introduces an ant colony algorithm onto a preset operational mode graph to perform multi-path consistency assessment on the consistency deviation within a sliding time window, obtain the optimal consistency path, and calculate the consistency matching degree based on the optimal consistency path. Furthermore, the module introduces a reinforcement learning mechanism to adaptively update the consistency assessment parameters and identify abnormal operational states based on the consistency matching degree and preset judgment rules.
