Description

Technical Field

[0001] The present application relates to the field of chemical technology, and in particular to a chemical safety detection method, system, terminal equipment and storage medium. Background Art

[0002] Toxic and hazardous gases in coal mines and chemical workplaces pose a fatal threat to workers. These gases can not only cause pneumoconiosis and even poisoning, but are also flammable and explosive, potentially leading to serious accidents. Therefore, research into toxic and flammable gas detection and alarm systems has garnered widespread attention worldwide.

[0003] In practice, toxic or flammable gas detection in China primarily relies on toxic or flammable gas detectors and alarms, which generate alarm signals to achieve safety management goals. However, sometimes localized gas concentrations are too high or the alarm system is left unused for extended periods, which can easily lead to false alarms and poor chemical safety detection results. Summary of the Invention

[0004] In order to improve the detection effect of chemical safety, the present application provides a chemical safety detection method, system, terminal equipment and storage medium.

[0005] In a first aspect, the present application provides a chemical safety detection method, comprising the following steps:

[0006] Perform sensitivity detection on the corresponding gas monitoring points in the target chemical area according to the sensitivity detection strategy, and generate corresponding sensitivity detection results;

[0007] If the sensitivity detection result does not meet the preset sensitivity standard, the corresponding abnormal gas monitoring point is obtained as sensitivity abnormality feedback information;

[0008] If the sensitivity detection result meets the preset sensitivity standard, obtaining gas detection data corresponding to the gas monitoring point;

[0009] If the gas detection data meets the corresponding hazardous gas alarm standard in the target chemical area, generating a corresponding first-level alarm signal according to the gas monitoring point, and obtaining the number of the first-level alarm signals;

[0010] If the number of the first-level alarm signal is single, determining the corresponding target gas monitoring point according to the first-level alarm signal, and obtaining the associated gas monitoring point corresponding to the target gas monitoring point;

[0011] If the associated gas monitoring point does not output the corresponding secondary alarm signal within the preset time interval, it is determined to be a false alarm;

[0012] If the associated gas monitoring point outputs the corresponding secondary alarm signal within the preset time interval, determining target associated gas monitoring points among the associated gas monitoring points according to the secondary alarm signal, and obtaining the number of the target associated gas monitoring points;

[0013] If the number of the target associated gas monitoring points exceeds a preset associated number threshold, the target gas monitoring points and the serial numbers and gas analysis data corresponding to the target associated gas monitoring points are obtained, and the corresponding hazardous gas distribution locations in the target chemical area are determined according to the serial numbers;

[0014] In combination with the hazardous gas distribution position and the gas analysis data, hazardous gas alarm indication information corresponding to the target chemical area is generated, and a corresponding rescue signal is generated according to the hazardous gas alarm indication information.

[0015] By adopting the above technical solution, before detecting the gas in the target chemical area, the sensitivity detection of the corresponding gas monitoring points in the target chemical area is first performed according to the sensitivity detection strategy, and the above sensitivity detection results are judged according to the preset sensitivity standard, which can reduce the occurrence of false alarms caused by long-term non-use of the gas monitoring system. Further, the gas detection data of each gas monitoring point in the gas monitoring system is analyzed according to the hazardous gas alarm standard. If a single gas monitoring point sends a first-level alarm signal, in order to reduce the occurrence of false alarms caused by excessive local gas concentration, it is obtained and judged whether the associated gas monitoring point corresponding to the target gas monitoring point is within the preset time interval Output the corresponding secondary alarm signal. If it is not output, the system determines that the above-mentioned primary alarm signal is a false alarm. If it is output, the target associated gas monitoring point in the associated gas monitoring point is further obtained and confirmed based on the above-mentioned secondary alarm signal. If the number of current target associated gas monitoring points exceeds the preset associated number threshold, it means that the hazardous gas has actually exceeded the standard. Then, combined with the target gas monitoring point and the serial number and gas analysis data corresponding to the target associated gas monitoring point, the specific hazardous gas distribution location and gas analysis data of the hazardous gas leak in the target chemical area are generated, and the corresponding hazardous gas alarm indication information is generated. Then the system automatically matches the corresponding rescue signal according to the hazardous gas alarm indication information. Due to the periodic sensitivity detection of each gas monitoring point in the gas monitoring system, and the analysis of the specific response of the target gas monitoring point and its corresponding target associated gas monitoring point in different target chemical areas, a comprehensive judgment is made as to whether the hazardous gas exceeds the standard, thereby improving the detection effect of chemical safety.

[0016] Optionally, performing sensitivity detection on corresponding gas monitoring points in the target chemical area according to the sensitivity detection strategy and generating corresponding sensitivity detection results includes the following steps:

[0017] Constructing a simulation environment corresponding to the gas monitoring point in the target chemical area according to the virtual reality technology in the sensitivity detection strategy;

[0018] Integrating the gas detection data corresponding to the gas monitoring point with the simulation environment to generate a sensitivity evaluation result corresponding to the gas monitoring point;

[0019] According to the sensitivity evaluation result, a sensitivity evaluation score corresponding to the gas monitoring point is set.

[0020] By adopting the above technical solution and constructing a corresponding simulation environment for the target chemical area based on virtual reality technology, the situation in the chemical area can be simulated more realistically, which can improve the detection accuracy of gas monitoring points. Secondly, by performing sensitivity evaluation on each gas monitoring point and generating its sensitivity evaluation score, sensitivity anomalies in the gas monitoring point can be discovered in a timely and effective manner, thereby reducing the occurrence of missed detection or false detection due to sensitivity problems and improving the detection effect of chemical safety.

[0021] Optionally, after obtaining the corresponding abnormal gas monitoring point as sensitivity abnormality feedback information if the sensitivity detection result does not meet the preset sensitivity standard, the following steps are further included:

[0023] Establishing an abnormal sensitivity analysis model corresponding to the abnormal gas monitoring point according to the abnormal features corresponding to the abnormal sensitivity detection data, and outputting a corresponding sensitive abnormal pattern;

[0024] In combination with the abnormal sensitivity pattern and the sensitivity adjustment parameter corresponding to the abnormal sensitivity pattern, a dynamic sensitivity adjustment mechanism corresponding to the abnormal gas monitoring point is established.

[0025] By adopting the above technical solution, the sensitivity of the gas monitoring point is adjusted in time according to the abnormal mode and adjustment parameters, and a corresponding dynamic sensitivity adjustment mechanism is established to adapt it to the gas detection needs under different conditions, thereby reducing false detections and missed detections, ensuring the timely discovery and treatment of potential hazardous gases, and thus improving the safety detection effect in the chemical industry.

[0026] Optionally, if the associated gas monitoring point outputs the corresponding secondary alarm signal within the preset time interval, then after determining target associated gas monitoring points among the associated gas monitoring points according to the secondary alarm signal and obtaining the number of the target associated gas monitoring points, the method further includes the following steps:

[0027] If there are multiple target-associated gas monitoring points, obtaining a response time interval for each target-associated gas monitoring point to output the corresponding secondary alarm signal within the preset time interval;

[0028] The hazardous gas safety assessment level corresponding to the target chemical area is set in combination with the gas detection data, the number of target associated gas monitoring points, and the response time interval.

[0029] By adopting the above technical solution, the degree of danger of the chemical area can be assessed according to the alarm signal triggering situation and the response time interval, and the corresponding safety level can be set. Then, the degree of diffusion of hazardous gases in the target chemical area can be analyzed and judged more accurately, thereby improving the detection effect of chemical safety.

[0030] Optionally, combining the gas detection data, the number of target-associated gas monitoring points, and the response time interval to set a hazardous gas safety assessment level corresponding to the target chemical area includes the following steps:

[0031] Obtaining the type of hazardous gas corresponding to the target chemical area in the gas detection data;

[0032] Evaluate the hazardous gas type according to the preset hazardous gas assessment standard and generate a corresponding first-level hazardous gas assessment result;

[0033] Evaluate the number of target-associated gas monitoring points and the response time interval according to a preset hazardous gas dispersion standard to generate a corresponding secondary hazardous gas assessment result;

[0034] The hazardous gas safety assessment level corresponding to the target chemical area is set in combination with the first-level hazardous gas assessment result and the second-level hazardous gas assessment result.

[0035] By adopting the above technical solution and setting the hazardous gas safety assessment level, a systematic safety assessment can be conducted on the target chemical area according to the actual situation and safety requirements, which will help improve the detection effect of chemical safety, timely discover and deal with potential hazardous gases, reduce the risk of accidents, and take corresponding preventive measures to ensure the safety of personnel and the environment.

[0039] The hazardous gas alarm indication information corresponding to the target chemical area is generated by combining the gas analysis data and the target selected leakage point, and the corresponding rescue signal is generated according to the hazardous gas alarm indication information.

[0040] By adopting the above technical solution, based on the density, flammability, toxicity and other characteristics of the hazardous gases in the target chemical area, and combined with the chemical equipment layout diagram of the target chemical area, the specific target selected leakage points in the initial verification leakage points are determined, and then based on the gas characteristics of the hazardous gases and the layout of the chemical equipment, the specific leakage location of the hazardous gases can be obtained more accurately, thereby improving the detection effect of chemical safety.

[0041] Optionally, after obtaining the physical and chemical properties of the hazardous gas corresponding to the gas analysis data and determining the target selected leakage point in the initial verification leakage point in combination with the chemical equipment layout diagram corresponding to the target chemical area, the following steps are further included:

[0042] If there is a historical gas leakage record at the target selected leakage point, combining the historical gas leakage record corresponding to the target selected leakage point and the gas analysis data to establish a hazardous gas leakage time series analysis model corresponding to the target selected leakage point;

[0043] Outputting an abnormal hazardous gas leakage pattern corresponding to the target selected leakage point according to the hazardous gas leakage time series analysis model;

[0044] Match the leakage event safety assessment level corresponding to the abnormal leakage pattern of hazardous gas, and generate a hazardous gas abnormal leakage analysis report corresponding to the target selected leakage point by combining the abnormal leakage pattern of hazardous gas and the leakage event safety assessment level.

[0045] By adopting the above technical solution, combined with the historical leakage records and gas analysis data of the target selected leakage point, a corresponding hazardous gas leakage time series analysis model is established, and a specific abnormal leakage pattern is output. The above abnormal leakage pattern is used to easily obtain the leakage characteristics and laws of the target selected leakage point in different time periods. At the same time, the corresponding safety assessment level is set to match the above different abnormal leakage patterns, which can further improve the detection level of chemical safety.

[0046] In a second aspect, the present application provides a chemical safety detection system, comprising:

[0047] The sensitivity detection module is used to perform sensitivity detection on the corresponding gas monitoring points in the target chemical area according to the sensitivity detection strategy and generate corresponding sensitivity detection results;

[0055] The rescue indication module is used to generate hazardous gas alarm indication information corresponding to the target chemical area in combination with the hazardous gas distribution location and the gas analysis data, and to generate a corresponding rescue signal according to the hazardous gas alarm indication information.

[0056] By adopting the above technical solution, before detecting the gas in the target chemical area, the sensitivity detection of the corresponding gas monitoring points in the target chemical area is first performed according to the sensitivity detection strategy in the sensitivity detection module, and the above sensitivity detection results are judged according to the preset sensitivity standard, which can reduce the occurrence of false alarms caused by long-term non-use of the gas monitoring system. Further, according to the hazardous gas alarm standard in the gas data acquisition module, the gas detection data of each gas monitoring point in the gas monitoring system is analyzed. If the first-level alarm module retrieves a single gas monitoring point and sends a first-level alarm signal, in order to reduce the occurrence of false alarms caused by excessive local gas concentration, the associated monitoring point acquisition module is used to obtain and judge whether the associated gas monitoring point corresponding to the target gas monitoring point is within the preset time interval. Output the corresponding secondary alarm signal. If no output is given, the system determines that the above-mentioned primary alarm signal is a false alarm through the false alarm identification module. If output is given, the target associated gas monitoring point in the associated gas monitoring point is further obtained and confirmed based on the secondary alarm signal output by the secondary alarm module. If the number of current target associated gas monitoring points exceeds the preset associated number threshold, it means that the hazardous gas has actually exceeded the standard. Then, the hazardous gas location determination module combines the target gas monitoring point and the target associated gas monitoring point’s corresponding serial number and gas analysis data to generate the specific hazardous gas distribution location and gas analysis data of the hazardous gas leak in the target chemical area, and generates the corresponding hazardous gas alarm indication information through the rescue indication module. Then, the system automatically matches the corresponding rescue signal according to the hazardous gas alarm indication information. Due to the periodic sensitivity detection of each gas monitoring point in the gas monitoring system, and the analysis of the specific response of the target gas monitoring point and its corresponding target associated gas monitoring point in different target chemical areas, a comprehensive judgment is made as to whether the hazardous gas exceeds the standard, thereby improving the detection effect of chemical safety.

Further, the gas detection data of each gas monitoring point in the gas monitoring system is analyzed according to the hazardous gas alarm standard. If a single gas monitoring point sends a first-level alarm signal, in order to reduce the occurrence of false alarms caused by excessive local gas concentration, it is obtained and judged whether the associated gas monitoring point corresponding to the target gas monitoring point is within the preset Assume that the corresponding secondary alarm signal is output within the time interval. If it is not output, the system determines that the above-mentioned primary alarm signal is a false alarm. If it is output, the target associated gas monitoring point in the associated gas monitoring point is further obtained and confirmed based on the above-mentioned secondary alarm signal. If the number of current target associated gas monitoring points exceeds the preset associated number threshold, it means that the hazardous gas has actually exceeded the standard. Then, the specific hazardous gas distribution location and gas analysis data of the hazardous gas leak in the target chemical area are generated by combining the target gas monitoring point and the serial number and gas analysis data corresponding to the target associated gas monitoring point, and the corresponding hazardous gas alarm indication information is generated.

[0074] The following is combined with Figure 1-8 This application is described in further detail.

[0075] The present application discloses a chemical safety detection method, such as Figure 1 As shown, the following steps are included:

[0076] S101. Perform sensitivity detection on the corresponding gas monitoring points in the target chemical area according to the sensitivity detection strategy, and generate corresponding sensitivity detection results;

[0077] S102. If the sensitivity detection result does not meet the preset sensitivity standard, the corresponding abnormal gas monitoring point is obtained as the abnormal sensitivity feedback information;

[0078] S103. If the sensitivity test result meets the preset sensitivity standard, the gas detection data corresponding to the gas monitoring point is obtained;

[0079] S104. If the gas detection data meets the corresponding hazardous gas alarm standard in the target chemical area, a corresponding first-level alarm signal is generated according to the gas monitoring point, and the number of first-level alarm signals is obtained;

[0080] S105. If the number of primary alarm signals is single, determine the corresponding target gas monitoring point according to the primary alarm signal, and obtain the associated gas monitoring point corresponding to the target gas monitoring point;

[0081] S106. If the associated gas monitoring point does not output the corresponding secondary alarm signal within the preset time interval, it is determined to be a false alarm;

[0082] S107. If the associated gas monitoring point outputs the corresponding secondary alarm signal within the preset time interval, the target associated gas monitoring point in the associated gas monitoring point is determined according to the secondary alarm signal, and the number of target associated gas monitoring points is obtained;

[0083] S108. If the number of target associated gas monitoring points exceeds the preset associated number threshold, the target gas monitoring points and the serial numbers and gas analysis data corresponding to the target associated gas monitoring points are obtained, and the corresponding hazardous gas distribution locations in the target chemical area are determined according to the serial numbers;

[0084] S109. Based on the hazardous gas distribution location and gas analysis data, generate hazardous gas alarm indication information corresponding to the target chemical area, and generate a corresponding rescue signal based on the hazardous gas alarm indication information.

[0085] In step S101, the target chemical area is an area within a chemical plant where hazardous gases are generated, including toxic, flammable, and explosive gases. For example, the target chemical area is the production area within a chemical plant. Various chemical reactions, gas separation, and gas purification processes are often involved in the production of chemical plants, which may generate hazardous gases such as toxic, flammable, or corrosive gases. Alternatively, the target chemical area is the waste liquid treatment area within a chemical plant, which processes wastewater and waste liquids, which may contain toxic substances or hazardous gases.

[0086] Secondly, to improve safety detection of hazardous gases in the target chemical plant area, gas monitoring points, or gas detection alarms, are deployed at regular intervals within the target chemical plant. Gas detection alarms are used to monitor the concentration of toxic, flammable, and explosive liquids and gases on the ground in the chemical plant. These alarms collect real-time concentration data of the relevant gases and generate judgments and alarms based on preset thresholds.

[0087] Specifically, the data from the gas detection alarm can be represented by n1, n2, n3, etc. These data represent the gas concentration values at different detection points. By continuously collecting data, the monitoring alarm can reflect the changes in gas at each detection point in real time. By deploying corresponding detection alarms in the target chemical area, the ground area of the chemical plant can be fully covered and changes in gas concentration at different locations can be monitored. This helps to provide early warning and timely response to possible dangerous situations, ensuring the safe operation of the chemical plant. In addition, the timely alarm system can also prompt staff to take emergency measures, reduce the possibility of accidents, and ensure the safety of people and the environment.

[0088] Furthermore, gas detection alarms can be deployed based on the three-dimensional space corresponding to the target chemical area. This refers to the area above the chemical plant building, including areas at different heights. For example, if the building is 4 meters high, multiple detection alarms can be deployed at different heights. The placement of these alarms can be determined based on specific safety requirements and risk assessments.

[0089] Specifically, in the area 1 meter above the factory building, a series of gas detection alarms marked a1, a2, a3... can be arranged to monitor and alarm about exhaust emissions, harmful gas concentrations or other possible dangerous situations; in the area 2 meters above the factory building, a series of gas detection alarms marked b1, b2, b3... can be arranged. These alarms may be used to monitor and alarm about fire risks, explosion risks or other possible dangerous situations; in the area 3 meters above the factory building, a series of gas detection alarms marked c1, c2, c3... can be arranged. These alarms are used to monitor and alarm about toxic gas leaks, chemical leaks or other possible dangerous situations; in the area 4 meters above the factory building, a series of gas detection alarms marked d1, d2, d3... can be arranged. These alarms may be used to monitor and alarm about oxygen concentration, poor ventilation or other possible dangerous situations.

[0090] Furthermore, the sensitivity detection strategy is primarily based on the aforementioned distribution of multiple detection alarms at different heights, covering the three-dimensional space of the chemical plant. The goal is to use the detection alarms to monitor the presence of potentially dangerous gases, fires, or other hazardous conditions, thereby identifying problems in advance and implementing appropriate emergency measures in a timely manner.

[0091] Specifically, sensitivity detection strategies rely primarily on sensitivity, or how sensitive the alarm is to a specific gas or event. Different alarms can utilize different sensors or detection technologies to detect and identify different types of hazardous situations. For example, smoke detectors might be used to detect fire risks, while gas or chemical sensors might be used to detect toxic gas leaks.

[0092] According to the sensitivity detection strategy described above, sensitivity detection can be performed on the gas monitoring points corresponding to each target chemical area in the chemical plant, and corresponding sensitivity detection results can be generated. The background monitoring system will occasionally drop data packets to the gas monitoring points to verify the sensitivity of the alarm and remotely control the switch.

[0093] It should be noted that the sensitivity test results described above primarily evaluate and describe the performance of gas detectors. Sensitivity testing provides data on the detector's response time to target gases, accuracy, and stability. These include: response time, which refers to the time it takes for the detector to sense the presence of the target gas and issue an alarm signal (or other form of warning); accuracy, which indicates how closely the detector's measurement matches the actual gas concentration; and stability, which refers to how well the detector maintains its performance over long-term operation.

[0094] In step S102, if the sensitivity test result does not meet the preset sensitivity standard, the corresponding abnormal gas monitoring point, i.e., the abnormal gas detection alarm, can be obtained and used as feedback information of sensitivity abnormality. This means that the detector at the gas monitoring point has shown performance or function that does not meet the requirements in the sensitivity test.

[0095] Preset sensitivity standards refer to indicators or requirements set in advance during sensitivity testing to evaluate the performance of gas detection alarms. These standards can be formulated based on factors such as specific application scenarios, the type of target gas being monitored, and its concentration range.

[0096] In step S103, if the sensitivity test result meets the preset sensitivity standard, gas detection data corresponding to the gas monitoring point can be further obtained, which means that the detector at the gas monitoring point has demonstrated performance or function that meets the requirements in the sensitivity test.

[0097] Gas detection data includes: gas concentration, which is the concentration of the target gas collected at the gas monitoring point; timestamps, which include a timestamp for each acquired gas detection data, recording the time of data collection; and data visualization, which allows for graphical or digital presentation of gas detection data for more intuitive understanding and analysis. Data visualization allows us to see the changing trends of gas concentrations over time, helping us determine whether the distribution or concentration levels of the target gas meet expectations.

[0098] In step S104, if the gas detection data meets the corresponding hazardous gas alarm standard for the target chemical area, it means that the detected gas concentration exceeds the preset gas safety threshold for the target chemical area. Different target chemical areas correspond to different hazardous gas alarm standards. This is because different chemical areas may have different hazardous gas types and concentration limits. Based on different working environments and safety requirements, corresponding alarm standards are set to ensure workplace safety.

[0099] Specifically, the corresponding hazardous gas alarm standards in the target chemical area include: hazardous gas types, that is, the standards will clearly stipulate the types of hazardous gases that need to be monitored in the area, such as combustible gases (such as methane, ethane), toxic gases (such as hydrogen sulfide, chlorine), etc.; alarm thresholds, that is, for different hazardous gases, the standards will set corresponding alarm thresholds. When the gas concentration exceeds or equals these thresholds, the corresponding level of alarm signal is triggered; alarm level, that is, according to the severity of the hazardous gas and its impact on the human body, the alarm is divided into different levels, such as level one alarm, level two alarm, etc., and each level corresponds to a different degree of danger.

[0100] Secondly, if the monitoring system determines that the gas detection data meets the corresponding hazardous gas alarm standards in the target chemical area, the corresponding gas monitoring point generates a corresponding level 1 alarm signal. To reduce the occurrence of false alarms caused by local high gas concentrations, the number of level 1 alarm signals is further obtained.

[0101] In step S105, if the number of the first-level alarm signal is only one, it means that only one target gas monitoring point has triggered the first-level alarm. According to this signal, the corresponding target gas monitoring point can be determined.

[0102] Secondly, if only one target gas monitoring point currently triggers a level 1 alarm, this could be a false alarm caused by excessively high local gas concentrations within the target chemical area. To mitigate this, the associated gas monitoring points corresponding to the target gas monitoring point are further acquired. Associated gas monitoring points are other gas monitoring points associated with the target gas monitoring point. These monitoring points can be located at the same or nearby locations as the target gas monitoring point and are used to monitor and verify whether the hazardous gases detected by the target gas monitoring point have reached the corresponding alarm level.

[0103] In steps S106 and S107, the preset time interval refers to a pre-set time range within the gas monitoring system for monitoring and evaluating the output results of the associated gas monitoring points. Specifically, when the target gas monitoring point triggers a level 1 alarm signal, the associated gas monitoring points begin monitoring and output corresponding level 2 alarm signals within the preset time interval.

[0104] The preset time interval can be determined based on specific application requirements and safety standards. This time interval typically consists of two points: the triggering time of the first-level alarm and the end time of the second-level alarm. The length of this time interval is adjusted based on factors such as the characteristics of the gas, the degree of hazard, and the speed of response.

[0105] It should be noted that within a preset time interval, the associated gas monitoring points will continuously monitor the detected gas concentrations and determine whether the level 2 alarm threshold has been reached. If a corresponding level 2 alarm signal is output during this period, it indicates that the concentration of the associated gas has reached or exceeded a dangerous level and is not a false alarm. If no level 2 alarm signal is output, or if the conditions for triggering a level 2 alarm are not met during this period, it can be considered a false alarm, resulting from excessively high local gas concentrations within the target chemical area.

[0106] Furthermore, if the associated gas monitoring point outputs a corresponding secondary alarm signal within a preset time interval, the corresponding target associated gas monitoring point can be determined based on the output secondary alarm signal. In order to further improve the accuracy of hazardous gas safety detection, the number of target associated gas monitoring points at this time is obtained to determine whether the number of target associated gas monitoring points exceeds the expected alarm number standard.

[0107] In step S108, the preset associated quantity threshold refers to a threshold set in advance in the gas monitoring system, which is used to determine whether the number of target associated gas monitoring points exceeds the expected associated quantity range. If it exceeds this threshold, it means that the number of associated gas monitoring points exceeds the expected or predetermined range, indicating that the current target chemical area actually has corresponding hazardous gas leakage and diffusion or exceeds the standard.

[0108] Secondly, the serial number is a unique identifier set to distinguish different monitoring points or devices. Each target gas monitoring point and target associated gas monitoring point has a unique serial number. Serial numbers can be set through hardware devices, software systems, or manual records.

[0109] Furthermore, based on the serial numbers of the target gas monitoring points and target-related gas monitoring points, combined with the chemical area's floor plan or monitoring point distribution map, the corresponding hazardous gas distribution locations within the target chemical area can be determined, thereby understanding the distribution of hazardous gases. Hazardous gas distribution locations refer to the distribution and spatial location of hazardous gases within a specific target chemical area. The gas analysis data corresponding to the target gas monitoring points and target-related gas monitoring points includes analysis results of the measured gas concentration values, timestamps, and other detection data.

[0110] Specifically, obtaining the distribution location of hazardous gases can be roughly divided into the following steps: obtaining the serial number of each target gas monitoring point and target associated gas monitoring point, as well as their specific location information. This information can be recorded and managed through equipment documentation, location tags, or databases; establishing a correlation model between the corresponding location and gas concentration based on the known location information and hazardous gas concentration data. This can be achieved through statistical analysis, mathematical modeling, or machine learning. The correlation model can consider factors such as gas diffusion, wind direction and speed, thereby inferring the possible hazardous gas concentrations at different locations; based on the above serial number and correlation model, the serial numbers of the target gas monitoring point and the target associated gas monitoring point are input into the model to infer the corresponding hazardous gas distribution location within the target chemical area. The model can provide a predicted value or probability distribution representing the possible hazardous gas concentration at each location.

[0111] In step S109, the determined hazardous gas distribution locations and real-time monitored gas concentration data are analyzed using techniques such as mathematical algorithms or rule engines. This analysis may include comparing actual measured values with preset safety limits or warning values, or comparing concentration values with historical data or models to determine whether potential hazards exist. Based on the hazardous gas analysis results, hazardous gas alarm indication information is generated for the target chemical area. This hazardous gas alarm indication information may include issuing a warning signal, triggering an alarm device, or displaying relevant warning information.

[0112] The warning information includes relevant information about the hazardous gas, such as gas type, concentration, hazardous characteristics, and emergency measures to be taken. This information helps workers understand the extent and nature of the danger and take appropriate protective measures.

[0113] Furthermore, based on the hazardous gas alarm indication information, a corresponding rescue signal can be further generated to notify relevant personnel or rescue agencies. The rescue signal can be sent through sound alarms, text message notifications, network message push, etc., to ensure that appropriate and necessary rescue actions are taken in a timely manner.

[0114] The chemical safety detection method provided in this embodiment first performs sensitivity detection on the corresponding gas monitoring points in the target chemical area according to the sensitivity detection strategy before detecting the gas in the target chemical area, and judges the above sensitivity detection results according to the preset sensitivity standard, which can reduce the occurrence of false alarms caused by the gas monitoring system not being used for a long time. The gas detection data of each gas monitoring point in the gas monitoring system is further analyzed according to the hazardous gas alarm standard. If a single gas monitoring point sends a first-level alarm signal, in order to reduce the occurrence of false alarms caused by excessive local gas concentration, it is obtained and judged whether the associated gas monitoring point corresponding to the target gas monitoring point is within the preset time. The corresponding secondary alarm signal is output within the interval. If it is not output, the system determines that the above-mentioned primary alarm signal is a false alarm. If it is output, the target associated gas monitoring point in the associated gas monitoring point is further obtained and confirmed based on the above-mentioned secondary alarm signal. If the number of current target associated gas monitoring points exceeds the preset associated number threshold, it means that the hazardous gas has actually exceeded the standard. Then, the specific hazardous gas distribution location and gas analysis data of the hazardous gas leak in the target chemical area are generated by combining the target gas monitoring point and the serial number and gas analysis data corresponding to the target associated gas monitoring point, and the corresponding hazardous gas alarm indication information is generated. Then, the system automatically matches the corresponding rescue signal according to the hazardous gas alarm indication information. Due to the periodic sensitivity detection of each gas monitoring point in the gas monitoring system, and the analysis of the specific response of the target gas monitoring point and its corresponding target associated gas monitoring point in different target chemical areas, a comprehensive judgment is made as to whether the hazardous gas exceeds the standard, thereby improving the detection effect of chemical safety.

[0115] In one implementation of this embodiment, Figure 2 As shown, step S101 is to perform sensitivity detection on the corresponding gas monitoring points in the target chemical area according to the sensitivity detection strategy, and generate the corresponding sensitivity detection results, which includes the following steps:

[0116] S201. Based on the virtual reality technology in the sensitivity detection strategy, a simulated environment corresponding to the gas monitoring point in the target chemical area is constructed;

[0117] S202. Integrate the gas detection data corresponding to the gas monitoring point with the simulation environment to generate a sensitivity evaluation result corresponding to the gas monitoring point;

[0118] S203. According to the sensitivity evaluation result, set the sensitivity evaluation score of the corresponding gas monitoring point.

[0119] In step S201, virtual reality technology can be applied to the sensitivity detection strategy to construct a simulated environment within the target chemical area. Specifically, virtual reality technology can be used to create a digital three-dimensional environment that simulates the actual scene of the target chemical area, including the location of gas monitoring points, equipment layout, and staff positions.

[0120] Specifically, VR technology includes: simulating gas concentrations, which uses VR to simulate and display the distribution of gas concentrations at different locations in real time. Based on actual measurement data or model input, the virtual environment displays the colors, textures, and concentration values of different gas concentrations, allowing operators to intuitively observe and experience the distribution of these gases; and simulating detection equipment, which simulates and presents real-world gas detection equipment such as sensors and instruments in a virtual environment. Operators can interact with VR equipment to simulate processes such as gas measurement, calibration, and alarms.

[0121] In steps S202 and S203, the collected gas detection data is integrated with the simulated environment. The data at the corresponding moment can be matched to the corresponding location in the simulated environment based on the data's timestamp. The gas concentration information at that monitoring point is displayed in the simulated environment for easy evaluation.

[0122] Next, sensitivity assessment is performed based on the gas concentrations in the simulated environment and the measured data at the monitoring point. The sensitivity of the monitoring point can be determined by comparing the difference between the actual concentration values and the measured data. If the measured data accurately reflects the changes in gas concentration in the simulated environment, the sensitivity of the monitoring point is high; otherwise, the sensitivity is low.

[0123] Furthermore, based on the sensitivity evaluation results obtained above, a sensitivity evaluation score is assigned to the gas monitoring point. For example, a scoring system with a full score of 100 can be used, with the weighting and criteria for the scores set based on the actual situation. Monitoring points with higher sensitivity can receive higher evaluation scores, while monitoring points with lower sensitivity can receive lower scores.

[0124] The chemical safety detection method provided in this embodiment constructs a simulation environment corresponding to the target chemical area based on virtual reality technology, which can more realistically simulate the situation in the chemical area and improve the detection accuracy of gas monitoring points. Secondly, by performing sensitivity evaluation on each gas monitoring point and generating its sensitivity evaluation score, the sensitivity abnormality of the gas monitoring point can be discovered in a timely and effective manner, thereby reducing the occurrence of missed detection or false detection due to sensitivity problems and improving the detection effect of chemical safety.

[0125] In one implementation of this embodiment, Figure 3As shown, in step S102, if the sensitivity detection result does not meet the preset sensitivity standard, the corresponding abnormal gas monitoring point is obtained as the sensitivity abnormality feedback information, and the following steps are also included:

[0126] S301. According to the abnormal sensitivity feedback information, obtain the abnormal sensitivity detection data corresponding to the abnormal gas monitoring point;

[0127] S302. According to the abnormal characteristics corresponding to the abnormal sensitivity detection data, establish an abnormal sensitivity analysis model corresponding to the abnormal gas monitoring point, and output the corresponding sensitive abnormal pattern;

[0128] S303. Combine the sensitivity abnormality mode and the sensitivity adjustment parameter corresponding to the sensitivity abnormality mode to establish a dynamic sensitivity adjustment mechanism for the corresponding abnormal gas monitoring point.

[0129] In step S301, when a gas monitoring point detects an abnormality, the abnormality information can be fed back to the user or relevant personnel through an alarm system, a data analysis system, etc. Such abnormal information may include gas concentration exceeding a preset threshold, detection equipment failure, environmental changes, etc.

[0130] Secondly, after receiving the abnormal sensitivity feedback information, the abnormal gas monitoring point can be tested for sensitivity and generate corresponding abnormal sensitivity detection data. The specific operations can be carried out in the following ways: detection point reset, that is, after confirming that the abnormal information is a false alarm or a fault, the abnormal monitoring point can be reset to restore it to normal. At this time, the gas detection data before and after the reset can be recorded for analyzing the change in sensitivity; manual intervention, that is, for monitoring points with large sensitivity abnormalities, manual intervention can be used to observe their sensitivity performance, such as increasing or decreasing the gas concentration, and observing whether the detection results of the monitoring point can accurately reflect the changes. At the same time, the detection data before and after the intervention are recorded for sensitivity evaluation; comparative analysis, that is, the abnormal monitoring point is compared and analyzed with other normally working monitoring points. By comparing the detection data of different monitoring points under the same environmental conditions, it can be determined whether there is a problem with the sensitivity of the abnormal point.

[0131] In steps S302 and S303, by analyzing and processing the abnormal sensitivity detection data, features or patterns in the abnormal data can be found. These features or patterns facilitate the determination of sensitivity issues at abnormal points. By establishing an abnormal sensitivity analysis model, abnormal features can be associated with sensitivity issues at monitoring points.

[0132] Secondly, after establishing the abnormal sensitivity analysis model, the corresponding sensitivity anomaly patterns can be output. Sensitivity anomaly patterns are patterns or regularities that describe the abnormal sensitivity characteristics of the outlier points. These patterns or regularities help better analyze the sensitivity issues of the outliers and provide a basis for subsequent sensitivity adjustment mechanisms.

[0133] Furthermore, by combining sensitivity anomaly patterns and sensitivity adjustment parameters, a dynamic sensitivity adjustment mechanism can be established for each abnormal gas monitoring point. This mechanism can adjust sensitivity based on real-time monitoring data and sensitivity anomaly patterns. By adjusting the sensitivity parameters, the sensitivity of the monitoring point can be dynamically increased or decreased to meet monitoring needs under different conditions.

[0134] The chemical safety detection method provided in this embodiment timely adjusts the sensitivity of the gas monitoring point and establishes a corresponding dynamic sensitivity adjustment mechanism according to the abnormal pattern and adjustment parameters, so that it can adapt to the gas detection needs under different conditions, thereby reducing false detections and missed detections, ensuring the timely discovery and treatment of potential hazardous gases, and thus improving the safety detection effect in the chemical field.

[0135] In one implementation of this embodiment, Figure 4 As shown, in step S107, i.e., if the associated gas monitoring point outputs a corresponding secondary alarm signal within a preset time interval, then the target associated gas monitoring point among the associated gas monitoring points is determined according to the secondary alarm signal, and the number of the target associated gas monitoring points is obtained, the following steps are further included:

[0136] S401. If the number of target associated gas monitoring points is multiple, then obtain the response time interval of each target associated gas monitoring point outputting the corresponding secondary alarm signal within a preset time interval;

[0137] S402. Based on the gas detection data and the corresponding number of target-associated gas monitoring points and the response time interval, set the hazardous gas safety assessment level corresponding to the target chemical area.

[0138] In steps S401 and S402, if the target is associated with a large number of gas monitoring points, the response time interval for each target-associated gas monitoring point to output a Level 2 alarm signal within a preset time interval can be further obtained. The response time interval is defined as the time difference between when the gas concentration reaches the Level 2 alarm threshold and when the corresponding gas monitoring point issues a Level 2 alarm signal within the preset time interval.

[0139] By determining the number of target-related gas monitoring points and comparing the response time intervals between different target-related gas monitoring points, we can determine the differences in the diffusion rate and range of hazardous gases at different locations. For example, a shorter response time interval between target-related gas monitoring points indicates a faster diffusion rate of hazardous gases near that monitoring point; a shorter response time interval indicates a slower diffusion rate of hazardous gases near that monitoring point.

[0140] It should be noted that in order to accurately assess the diffusion rate of hazardous gases, it is necessary to combine professional gas diffusion models with monitoring and analysis of on-site data in the target chemical area in actual use.

[0141] Furthermore, based on the number of target-associated gas monitoring points and the response time intervals for these monitoring points to output secondary alarm signals within a preset time interval, a comprehensive assessment of the hazardous gas safety level of the target chemical area can be performed. Depending on the degree of hazard, the target chemical area can be divided into different hazardous gas safety assessment levels. The gas detection data in this embodiment includes the properties and concentrations of the different monitored hazardous gases, as well as any instances where the secondary alarm threshold has been exceeded.

[0142] For example, if the gas concentration exceeds the second-level alarm standard and is explosive, or the monitoring point response time interval is short and the gas concentration is high, it may pose a serious threat to personnel and facilities in a short period of time. In this case, the hazardous gas safety assessment level of the corresponding target chemical area will be set to level one, that is, high-risk level.

[0143] For example, if the gas concentration exceeds the second-level alarm standard but is not explosive, or the response time interval of the monitoring point is moderate, and the gas concentration is within a certain range, it may pose a certain threat to personnel and facilities. In this case, the hazardous gas safety assessment level of the corresponding target chemical area is set to level two, which is a higher risk level.

[0144] For example, if gas concentrations are close to or slightly below the Level 2 alarm threshold, or if the response interval at a monitoring point is long but the gas concentration is high, potentially posing a risk to personnel and facilities, the corresponding target chemical area's hazardous gas safety assessment level will be set to Level 3, or medium hazard. Alternatively, if gas concentrations are below the Level 2 alarm threshold and stable, the response interval at a monitoring point is long, and the gas concentration is low, indicating a relatively low risk, the corresponding target chemical area's hazardous gas safety assessment level will be set to Level 4, or low hazard.

[0145] The chemical safety detection method provided in this embodiment can conduct a systematic safety assessment of the target chemical area according to the actual situation and safety requirements based on the set hazardous gas safety assessment level, thereby helping to improve the chemical safety detection effect, timely discover and deal with potential hazardous gases, reduce accident risks, and take corresponding preventive measures to ensure the safety of personnel and the environment.

[0146] In one implementation of this embodiment, Figure 5 As shown, step S402, that is, combining the gas detection data and the number of target-associated gas monitoring points and the response time interval, sets the hazardous gas safety assessment level of the corresponding target chemical area, including the following steps:

[0147] S501. Obtain the type of hazardous gas corresponding to the target chemical area in the gas detection data;

[0148] S502. Evaluate the hazardous gas type according to the preset hazardous gas assessment standard and generate the corresponding first-level hazardous gas assessment result;

[0149] S503. Evaluate the number of target-associated gas monitoring points and the response time interval according to the preset hazardous gas dispersion standard to generate the corresponding secondary hazardous gas assessment results;

[0150] S504. Combine the first-level hazardous gas assessment results and the second-level hazardous gas assessment results to set the hazardous gas safety assessment level for the corresponding target chemical area.

[0151] In step S501 to step S502, to obtain the type of hazardous gas in the target chemical area, it is first necessary to check the records of the monitoring points in the gas detection data. Based on this data, the type of hazardous gas present in the target chemical area can be determined.

[0152] Pre-set hazardous gas assessment standards are developed based on relevant safety regulations and technical specifications. These standards typically include indicators such as hazardous gas concentration and toxicity. Based on these standards, the type of hazardous gas detected can be assessed.

[0153] Next, each detected hazardous gas type is evaluated based on the pre-defined assessment criteria, resulting in a corresponding Level 1 Hazardous Gas Assessment result. This Level 1 Hazardous Gas Assessment result identifies which gas types within the target chemical area are classified as Level 1 Hazards. This Level 1 Hazardous Gas Assessment result indicates the potential threats posed by these gases to personnel and facilities.

[0154] In steps S503 and S504, the preset hazardous gas dispersion standards are established based on relevant safety regulations and technical specifications. These standards typically include indicators such as hazardous gas concentration, toxicity, and dispersion range. Based on these standards, the number of target-linked gas monitoring points and the response time interval can be evaluated.

[0155] The secondary hazardous gas assessment evaluates the type and concentration of monitored hazardous gases based on preset hazardous gas dispersion standards. Based on the secondary hazardous gas assessment results, hazardous gases can be classified into different hazard levels. Combining the primary and secondary hazardous gas assessment results, a comprehensive hazardous gas safety assessment level can be established for the target chemical area. Based on the specific assessment results, the hazardous gases in the target chemical area are classified into different levels, such as high risk, medium risk, and low risk, to facilitate appropriate management and control measures.

[0156] In one implementation of this embodiment, Figure 6 As shown, step S109 is to generate hazardous gas alarm indication information corresponding to the target chemical area by combining the hazardous gas distribution location and gas analysis data, and generate a corresponding rescue signal according to the hazardous gas alarm indication information, including the following steps:

[0157] S601. Determine the initial leakage point corresponding to the target chemical area based on the distribution location of hazardous gases;

[0158] S602. Obtain the physical and chemical properties of the corresponding hazardous gases in the gas analysis data, and determine the target selected leak point in the initial verification leak point in combination with the chemical equipment layout corresponding to the target chemical area;

[0159] S603. Combine the gas analysis data and the target selected leakage point to generate hazardous gas alarm indication information corresponding to the target chemical area, and generate a corresponding rescue signal based on the hazardous gas alarm indication information.

[0160] In step S601, the initial leakage points of the target chemical area are determined based on the distribution of hazardous gases in order to preliminarily determine areas where leakage risks may exist so as to facilitate further monitoring and preventive measures.

[0161] Based on the distribution of hazardous gases, areas with potential leakage risks are initially identified, potentially serving as potential leak points. By comparing the distribution of hazardous gases with relevant information on equipment, pipelines, and containers, potential leak points can be preliminarily determined. This initial identification of leak points aims to proactively identify potential leak risks and enable the implementation of appropriate preventative measures. This helps avoid potential accidents and dangerous situations, ensuring the safety of the target chemical area. This initial identification of leak points requires comprehensive analysis and assessment, including consideration of factors such as the characteristics of the hazardous gases, potential leakage pathways, and the safety of the equipment and processes.

[0162] In step S602, the physical and chemical properties of the corresponding hazardous gas can be obtained by referring to relevant chemical databases, safety data sheets, and laboratory test results. These data can provide important information about the hazardous gas's flash point, explosion limit, vapor density, and the effects of gas concentration on the human body.

[0163] Secondly, a chemical equipment layout diagram of the target chemical area is a drawing that shows the spatial distribution and locational relationships of the various chemical equipment, pipelines, and storage facilities within the area. It typically includes annotations and labels to accurately illustrate the location and function of the equipment. By combining the physical and chemical properties of hazardous gases with the chemical equipment layout diagram of the target chemical area, equipment or areas with potential leakage risks can be identified. By analyzing the design, operation, and maintenance of the equipment and pipelines, the location of potential leaks can be preliminarily determined.

[0164] Furthermore, when finalizing the target leak points, combining the physical and chemical properties of hazardous gases with the chemical equipment layout of the target chemical area for analysis can more accurately identify potential leak points. A detailed analysis of the equipment and pipeline layout, materials, and connection methods can determine which equipment and areas may pose a leak risk.

[0165] It should be noted that target leak points refer to specific equipment or areas with potential leak risks identified during the initial leak point identification process based on the distribution of hazardous gases and the chemical equipment layout. This is the result of screening and confirming the initial leak points, combining the physical and chemical properties of the corresponding hazardous gases from gas analysis data with the chemical equipment layout corresponding to the target chemical area. This serves to guide subsequent leak monitoring, risk assessment, and the development of protective measures.

[0166] In step S603, the monitoring system generates hazardous gas alarm information for the target chemical area based on the identified target leak point and gas analysis data. This information includes alarm notification methods, such as sound, light, and display screen, as well as alarm content, including the specific location of the target chemical area, the specific equipment and location where the hazardous gas leak occurred, the type of hazardous gas generated, and its extent of spread.

[0167] Secondly, based on the specific alarm indication information of the hazardous gas, the corresponding rescue signal type is determined and issued. The rescue signal type is determined by factors such as the severity of the hazardous gas and the distance, such as an emergency distress signal or an evacuation signal.

[0168] The chemical safety detection method provided in this embodiment determines the specific target selected leakage points in the initial verification leakage points based on the density, flammability, toxicity and other characteristics of the hazardous gases in the target chemical area, combined with the chemical equipment layout diagram of the target chemical area. Then, based on the gas characteristics of the hazardous gases and the layout of the chemical equipment, the specific leakage location of the hazardous gases can be obtained more accurately, thereby improving the chemical safety detection effect.

[0169] In one implementation of this embodiment, Figure 7 As shown, after obtaining the physical and chemical properties of the hazardous gas corresponding to the gas analysis data in step S602 and determining the target selected leakage point in the initial verification leakage point in combination with the chemical equipment layout diagram corresponding to the target chemical area, the following steps are also included:

[0170] S701. If the target selected leakage point has a historical gas leakage record, then the target selected leakage point corresponding to the historical gas leakage record and gas analysis data, establish the corresponding target selected leakage point hazardous gas leakage time series analysis model;

[0171] S702. Output the abnormal leakage pattern of hazardous gas corresponding to the target selected leakage point according to the hazardous gas leakage time series analysis model;

[0172] S703. Match the leakage event safety assessment level corresponding to the abnormal leakage pattern of hazardous gas, and generate a hazardous gas abnormal leakage analysis report corresponding to the target selected leakage point by combining the abnormal leakage pattern of hazardous gas and the leakage event safety assessment level.

[0173] In steps S701 and S702, if a historical gas leakage record exists for the target leakage point, it indicates that the target leakage point has experienced a gas leakage event in the past. Historical gas leakage records refer to the historical data recorded and archived for gas leakage events that occurred in the specific location, equipment, or process corresponding to the target leakage point. These records may include the time, location, leakage volume, leakage duration, and related monitoring data.

[0174] The Hazardous Gas Leak Time Series Analysis Model is a model for analyzing and predicting hazardous gas leaks. Based on historical gas leak records and related gas analysis data at a targeted leak point, it establishes a time series pattern of leak events to reveal the patterns and characteristics of leaks and predict future leaks.

[0175] Specifically, by using the aforementioned hazardous gas leakage time series analysis model to learn and analyze historical leakage records of a target leakage point, we can obtain the time series pattern corresponding to the leakage event, that is, the abnormal leakage pattern of hazardous gas. For example, periodic leakage, seasonal leakage, and gradually increasing or decreasing trends can be obtained.

[0176] Secondly, in addition to the temporal pattern of the leak event itself, the model can also analyze environmental and operational factors that may affect the leak, such as temperature, humidity, pressure, equipment operating status, etc. These factors may affect the frequency and scale of leak events.

[0177] It should be noted that, based on the temporal patterns and related factors of leak events, statistical methods, time series analysis methods, or machine learning techniques can be used to establish a corresponding leak time series analysis model. The model can include functions such as parameter estimation, trend prediction, periodicity analysis, and anomaly detection to reveal and predict changes and trends in hazardous gas leak events.

[0178] In step S703, the abnormal leakage pattern of hazardous gas may be classified into different safety assessment levels according to factors such as the scale, frequency, duration, and impact range of the leakage event. The specific matching and assessment level may be determined according to specific standards and guidelines.

[0179] For example, the first level safety assessment level corresponds to leakage incidents with smaller scale, lower frequency and shorter duration. The leaked gas can be quickly controlled or spread over a limited range, with less impact on personnel and the environment. The second level safety assessment level corresponds to leakage incidents with medium scale, medium frequency and longer duration. The leaked gas may take some time to control or spread over a wide range, and the impact on personnel and the environment is relatively controllable. The third level safety assessment level corresponds to leakage incidents with larger scale, higher frequency and longer duration. The leaked gas is difficult to control quickly, spreads over a wider range, and has a greater impact on personnel and the environment. Emergency response measures may be required.

[0180] Next, based on the identified target leak points and related historical data, combined with the hazardous gas leakage patterns and safety assessment levels, a comprehensive analysis of the hazardous gas leakage at the target leak points is conducted. This includes the potential impact of the leakage incident, the potential degree of personal injury and environmental pollution, as well as possible emergency response and preventive measures. A hazardous gas leakage analysis report for the target leak point is then generated, detailing all of the aforementioned data. This provides accurate analysis results and assessments to relevant personnel and decision-makers, supporting the development of appropriate safety measures and management strategies.

[0181] The chemical safety detection method provided in this embodiment combines the historical leakage records and gas analysis data of the target selected leakage point to establish a corresponding hazardous gas leakage time series analysis model and output a specific abnormal leakage pattern. The above abnormal leakage pattern is used to facilitate the acquisition of the leakage characteristics and regularities of the target selected leakage point in different time periods. At the same time, the corresponding safety assessment levels are set and matched for the above different abnormal leakage patterns, which can further improve the detection level of chemical safety.

[0182] The present application embodiment discloses a chemical safety detection system, such as Figure 8 Shown, including:

[0183] Sensitivity detection module 1, used to perform sensitivity detection on the corresponding gas monitoring points in the target chemical area according to the sensitivity detection strategy, and generate corresponding sensitivity detection results;

[0184] Abnormal sensitivity feedback module 2, if the sensitivity detection result does not meet the preset sensitivity standard, then the abnormal sensitivity feedback module 2 is used to obtain the corresponding abnormal gas monitoring point as abnormal sensitivity feedback information;

[0185] Gas data acquisition module 3, if the sensitivity detection result meets the preset sensitivity standard, then the gas data acquisition module 3 is used to obtain the gas detection data corresponding to the gas monitoring point;

[0186] The first-level alarm module 4 is used to generate a corresponding first-level alarm signal according to the gas monitoring point if the gas detection data meets the corresponding hazardous gas alarm standard in the target chemical area, and obtain the number of first-level alarm signals;

[0187] The associated monitoring point acquisition module 5 is used to determine the corresponding target gas monitoring point according to the first-level alarm signal if the number of the first-level alarm signal is single, and to obtain the associated gas monitoring point corresponding to the target gas monitoring point;

[0188] The false alarm identification module 6 is used to determine that the alarm is a false alarm if the associated gas monitoring point does not output the corresponding secondary alarm signal within a preset time interval;

[0189] Secondary alarm module 7, if the associated gas monitoring point outputs a corresponding secondary alarm signal within a preset time interval, the secondary alarm module 7 is used to determine the target associated gas monitoring point among the associated gas monitoring points according to the secondary alarm signal, and obtain the number of the target associated gas monitoring points;

[0190] The hazardous gas location determination module 8 is configured to obtain the serial numbers and gas analysis data corresponding to the target gas monitoring points and the target associated gas monitoring points if the number of the target associated gas monitoring points exceeds a preset associated number threshold, and determine the corresponding hazardous gas distribution location in the target chemical area based on the serial numbers;

[0191] The rescue indication module 9 is used to generate hazardous gas alarm indication information corresponding to the target chemical area in combination with the hazardous gas distribution location and gas analysis data, and to generate a corresponding rescue signal according to the hazardous gas alarm indication information.

[0192] The chemical safety detection system provided in this embodiment, before detecting the gas in the target chemical area, first performs sensitivity detection on the corresponding gas monitoring points in the target chemical area according to the sensitivity detection strategy in the sensitivity detection module 1, and judges the above sensitivity detection results according to the preset sensitivity standard, which can reduce the occurrence of false alarms caused by long-term non-use of the gas monitoring system. Further, according to the hazardous gas alarm standard in the gas data acquisition module 3, the gas detection data in each gas monitoring point in the gas monitoring system is analyzed. If the first-level alarm module 4 retrieves a single gas monitoring point to send a first-level alarm signal, in order to reduce the occurrence of false alarms caused by excessive local gas concentration, the associated monitoring point acquisition module 5 is used to obtain and judge whether the associated gas monitoring point corresponding to the target gas monitoring point is within the preset time zone. The corresponding secondary alarm signal is output within a certain period of time. If it is not output, the system determines that the above-mentioned primary alarm signal is a false alarm through the false alarm identification module 6. If it is output, the target associated gas monitoring point in the associated gas monitoring point is further obtained and confirmed according to the secondary alarm signal output by the secondary alarm module 7. If the number of current target associated gas monitoring points exceeds the preset associated number threshold, it means that the hazardous gas has actually exceeded the standard. Then, the hazardous gas location determination module 8 combines the target gas monitoring point and the target associated gas monitoring point with the serial number and gas analysis data corresponding to the target gas monitoring point to generate the specific hazardous gas distribution location and gas analysis data of the hazardous gas leak in the target chemical area, and generates the corresponding hazardous gas alarm indication information through the rescue indication module 9. Then, the system automatically matches the corresponding rescue signal according to the hazardous gas alarm indication information. Due to the periodic sensitivity detection of each gas monitoring point in the gas monitoring system, and the analysis of the specific response of the target gas monitoring point and its corresponding target associated gas monitoring point in different target chemical areas, a comprehensive judgment is made as to whether the hazardous gas exceeds the standard, thereby improving the detection effect of chemical safety.
