Description

Technical Field

[0001] The present application relates to the technical field of operation management, and in particular to a special operation management method and system based on personnel positioning. Background Art

[0002] With the rapid development of industrialization, special operation management has become an important part of enterprise safety production. Special operations often involve high-risk and high-complexity operations, such as chemical handling, high-altitude operations, and confined space operations. These operations have extremely high requirements for personnel safety, environmental protection, and operation efficiency.

[0003] Traditional special operation management methods rely on manual inspection and paper records, and often lack a complete and systematic basic operation database as data support. They are not only inefficient, but also have obvious limitations in risk assessment, operation monitoring and emergency response. Traditional methods often roughly divide the operation area and lack detailed assessment of each sub-area. This leads to inaccurate judgments on the safety of the operating environment, and it is impossible to provide targeted safety measures for operators. It also makes it difficult to carry out risk assessment and environmental analysis in depth, and can only rely on limited experience and manual operations, resulting in inaccurate and subjective assessment results. Therefore, it is particularly important to develop a method that can effectively assess and manage the risks of special operations. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0063] Figure 1 It is a schematic diagram of a special operation management method based on personnel positioning provided in an embodiment of the present application. DETAILED DESCRIPTION

[0064] Below, the present application is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0065] Some embodiments of the present application provide a special operation management method based on personnel positioning, the method comprising:

[0066] S1. Configure a basic operation library; the basic operation library at least includes a gas analysis library and an operation ticket sample library;

[0067] S2. Divide the first area and obtain a first score for the first area;

[0068] S3, obtaining target operation elements, wherein the target operation elements include an operation area, and dividing a first area into a first sub-area according to the operation area; performing risk assessment on the target operation based on the risk assessment model according to the target operation elements; obtaining a comprehensive score of the target operation, and determining a work ticket and a first risk score of the first sub-area according to the comprehensive score of the target operation; and generating an operation permit according to the on-site assessment result and the comprehensive score of the target operation;

[0069] S4, obtaining the working environment information in the first area, analyzing the working environment information based on the basic operation database, obtaining the environmental coefficient, and performing environmental control according to the environmental analysis result;

[0070] S5. Divide the dangerous sub-areas according to the first risk score, and adjust the dangerous sub-areas according to the environmental coefficient; obtain the real-time displacement of personnel and moving objects, determine whether the personnel have violated the regulations and / or entered the dangerous sub-areas; and issue an early warning based on the determination result.

[0071] The working principle of the above technical solution is as follows: the system will establish a basic operation library, which contains at least a gas analysis library and an operation ticket sample library, to provide basic data and reference for subsequent operation management and risk assessment; divide a first area, and give a first score based on the specific situation in the area, which may be based on historical data, environmental conditions, operation complexity and other factors; obtain the target operation elements; these elements include the operation area, etc.; based on these elements, the system will use the risk assessment model to conduct a risk assessment on the target operation and obtain a comprehensive score for the target operation; this score reflects the overall risk level of the operation; determine the specific operation ticket based on this score, and conduct a risk score for the sub-area within the first area (i.e., the first risk score). In addition, the system will generate an operation permit based on the on-site assessment results and the comprehensive score of the target operation to ensure the safe conduct of the operation.

[0072] During the operation, the operating environment information in the first area will be obtained, and the gas analysis library in the basic operation library will be used to analyze the environmental information; the analysis result will be converted into an environmental coefficient, which reflects the current working environment status; based on this environmental coefficient, the system will perform corresponding environmental control to ensure the safety of the working environment.

[0073] Finally, the system will divide the first area into dangerous sub-areas based on the first risk score and adjust the dangerous sub-areas based on the environmental factor; at the same time, the system will obtain the displacement information of personnel and moving objects in real time, and use this information to determine whether the personnel are performing illegal operations or have entered the dangerous sub-areas. If the system detects any unsafe behavior, it will immediately issue an early warning to ensure the safety of the operators.

[0074] Overall, this working method provides an effective special operations management method through comprehensive risk assessment, environmental monitoring and real-time displacement tracking, aiming to maximize the safety of operators and improve operation efficiency.

[0075] The effects of the above technical solutions are as follows: by conducting risk assessment on the target operation through the risk assessment model, the potential risks in the operation can be accurately identified, so as to take corresponding preventive measures; by obtaining the operation environment information in real time and performing environmental control based on this information, the operation environment can be ensured to be always in a safe state. Dividing dangerous sub-areas and conducting real-time warnings can prevent personnel from entering dangerous areas or performing illegal operations, thereby avoiding accidents; configuring the basic operation library, including the gas analysis library and the operation ticket sample library, provides standardized guidance and reference for the operation, reducing unnecessary preparation work and repetitive work; automatically generating operation permits based on the risk assessment results simplifies the operation approval process and improves work efficiency. Real-time acquisition of the displacement information of personnel and moving objects can timely discover and solve bottleneck problems in the operation and ensure the smooth progress of the operation; through automation and intelligent means of operation management and environmental monitoring, manpower input and material consumption are reduced; accurate risk assessment and warning can reduce losses and compensation caused by accidents and reduce the operating costs of enterprises; risk assessment results and warning information can help managers to timely discover and solve potential problems, improving the timeliness and accuracy of decision-making.

[0076] In summary, the special operation management method based on personnel positioning can significantly improve the safety, efficiency and decision-making support capabilities of the operation and reduce management costs. This has important practical application value for enterprises that need to carry out high-risk operations or special operations.

[0077] In some embodiments, the S1 includes:

[0078] The gas analysis library includes gas type, gas name and safety threshold;

[0079] The operation ticket sample library includes historical operation names, operation types, operation times, operation areas, operation personnel, and safety protection measures.

[0080] The principle and effect of the above technical solution are as follows: the basic operation library provides basic data and information support for the entire operation management process, of which the gas analysis library and the operation ticket sample library are two important components. The gas analysis library first contains various gas types that may exist in the operating environment and their corresponding names; this is the basis for gas detection and analysis.

[0081] For each type of gas, there will be one or more safety thresholds; these thresholds are set based on the nature of the gas, the impact of the concentration on human health or equipment safety; once the concentration of a certain gas in the working environment exceeds these thresholds, corresponding safety measures need to be taken; the safety thresholds in the gas analysis library can provide a clear reference standard for gas detection in the working environment. Once it is found that the gas concentration exceeds or falls below the safety threshold, timely response measures can be taken to avoid accidents.

[0082] The sample database of operation tickets contains relevant information of historical operations, such as the name, type, time, area and operators involved in the operation. This information provides a reference for new operations and helps to identify the risks and hidden dangers that may arise in similar operations. The sample database of operation tickets also records the safety protection measures taken for various operations. These measures are based on historical experience and professional judgment and are designed to ensure the safety of the operation.

[0083] The safety thresholds in the gas analysis library can provide a clear reference standard for gas detection in the working environment. Once the gas concentration is found to exceed or fall below the safety threshold, timely countermeasures can be taken to avoid accidents. The historical operation information and safety protection measures in the work ticket sample library provide rich experience and guidance for new operations, which helps to reduce the risks and uncertainties in the operation. By referring to the historical information in the work ticket sample library, operation managers can formulate operation plans and safety protection measures more quickly and accurately, further improving operation efficiency.

[0084] In some embodiments, the S2 includes:

[0085] Obtain a 3D model of the area; the 3D model can be obtained through a variety of methods, such as using laser scanning technology, drone aerial photography combined with image processing technology, or 3D modeling based on existing architectural design drawings; ensure that the 3D model can accurately reflect the actual conditions of the working environment, including terrain, buildings, equipment layout, etc.;

[0086] Divide the first area according to the regional functions and the regional three-dimensional model; analyze the regional functions, including understanding the purpose of each area, basic operation types, possible sources of danger, etc.;

[0087] Scoring the first area and obtaining a first score;

[0088] The first rating is:

[0089] C i =a×Z i +b×GD i

[0090] Z i =w1×GI i +w2×GRS i

[0091]

[0092] I i =L i +E i

[0093]

[0094] Among them, C i is the first score of the ith region, GD i The hazard coefficient score D of the i-th area i The normalized result of Z i is the importance score of the i-th region, a and b are coefficients, 0 <a<1,0<b<1,a+b=1;GI i For I i Normalized result of GRS i RS i The normalized result of , w1, w2 are weight coefficients; I i is the correlation frequency between the ith region and other regions; RS i Score the importance of resources in the i-th region; L i is the number of material flows in the i-th area within the preset time; E i is the total number of times the i-th region collaborates with devices in other regions within the preset time; pij is the weight coefficient of the j-th resource in the i-th region; Sij is the importance score of the j-th resource in the i-th region, and n is the number of resources in the i-th region.

[0095] The risk factor score D i It is determined based on the complexity of the terrain, the density of equipment layout, the number of hazardous materials in the area, and the score of hazardous materials; the hazard scoring factors include the complexity of the terrain, the density of equipment layout, the number of hazardous materials and the score; each factor has a score range, for example, from 1 (lowest) to 10 (highest).

[0096] Assume that there are g types of dangerous goods in the first area. Each dangerous goods has a score based on its toxicity, flammability, explosiveness and other characteristics. The total score of dangerous goods can be calculated as the sum of the product of each dangerous goods score and its quantity, and normalized:

[0097] The three factors are combined to calculate the risk factor score; each factor can be weighted averaged to obtain the final risk factor score D i .

[0098] The working principle of the above technical solution is: an accurate three-dimensional model of the working environment can be constructed through laser scanning technology, drone aerial photography combined with image processing technology, or based on existing architectural design drawings; this model should accurately reflect the actual situation of terrain, buildings, equipment layout, etc.; the functions of the working area are analyzed in detail to understand the purpose of each area, the basic operation type and possible sources of danger. Combined with the three-dimensional model of the area, the working environment is divided into several first areas, each of which is defined according to its functional characteristics and operation requirements.

[0099] For each first area, a comprehensive scoring method is used to quantify its importance and degree of danger.

[0100] The scoring model consists of two main parts: importance score and risk factor score.

[0101] The importance score consists of two parts: the frequency of inter-regional connections and the resource importance score.

[0102] The frequency of inter-regional associations reflects the frequency of interaction between a region and other regions, including the number of material flows and the total number of equipment collaborations. The higher these interaction frequencies are, the greater the importance of the region. The preset time can be set as needed. It can be a phased cycle of a single operation in the region, or it can be preset for one week, two weeks, one month, etc. There is no specific limitation here.

[0103] The resource importance score takes into account the importance of resources in the region, including resource weight coefficients and resource importance ratings. These resources may be equipment, materials, or other important assets.

[0104] The first score is a weighted sum of the importance score and the criticality score, where a and b are coefficients used to adjust the relative weights of importance and criticality.

[0105] The hazard factor score is determined based on the complexity of the terrain, the density of equipment layout, the number of hazardous materials in the area, and the score of the hazardous materials. Factors such as terrain complexity, equipment layout density, and the number of hazardous materials directly affect the safety of the area; the score of hazardous materials may be based on their toxicity, flammability, explosiveness, and other characteristics.

[0106] For example, hazard rating factors include terrain complexity, equipment layout density, and the number and rating of hazardous materials; each factor has a rating range, such as from 1 (lowest) to 10 (highest).

[0107] Assume that there are g types of dangerous goods in the first area. Each dangerous goods has a score based on its toxicity, flammability, explosiveness and other characteristics. The total score of dangerous goods can be calculated as the sum of the product of each dangerous goods score and its quantity, and normalized:

[0108] The three factors are combined to calculate the risk factor score; each factor can be weighted averaged to obtain the final risk factor score D i .

[0109] Through the scoring mechanism, each area in the operating environment can be quantitatively evaluated, providing a scientific basis for subsequent operation management, resource allocation and risk control. At the same time, this also enables managers to more intuitively understand the importance and risk level of each area, so as to make more reasonable decisions.

[0110] The effect of the above technical solution is: by combining the three-dimensional model and functional analysis of the area, the potential risks in the area can be identified and understood more accurately; not only physical factors such as terrain and equipment layout are taken into account, but also the function of the area, operation type and hazard source, thereby improving the accuracy of risk assessment.

[0111] The first scoring takes into account the normalized processing results of the importance score and the risk factor score of the region, making resource allocation more reasonable; based on the scoring results, managers can focus on monitoring areas with high importance and high risk; through detailed scoring and evaluation of the region, potential risk points can be discovered in a timely manner and corresponding preventive measures can be taken. This helps to reduce the occurrence of accidents and ensure the safety of personnel and property; the scoring results can be used as a basis for continuous improvement; based on the scoring results, the weak links of the region can be analyzed, improvement measures can be formulated, and the improvement effects can be continuously monitored and evaluated to achieve continuous improvement of safety management.

[0112] In summary, using the above steps can improve the accuracy of risk assessment, optimize resource allocation, improve decision-making efficiency, prevent potential risks, and provide a basis for continuous improvement.

[0113] In some embodiments, the S3 includes:

[0114] Acquire multiple elements of the target operation, wherein the multiple elements include operation type, operation area, operation date, operation content, operation method, and safety protection measures;

[0115] Determine the specific location of the operation area within the first area, including the target operation boundary and scope;

[0116] Obtaining a safe distance between the first area and the target operation area;

[0117] The first sub-area is divided based on the specific location of the target operation in the first area and the safety distance.

[0118] In some embodiments, a comprehensive score of the target operation is obtained based on a risk assessment model according to multiple elements of the target operation;

[0119] Determine whether there is a cross operation of the target operation in the same area;

[0120] If not, determining a first risk score for the first sub-region according to the comprehensive score of the target operation and the score of the first region; wherein the risk score of the first sub-region may be a weighted sum of the first region score and the comprehensive score of the target operation;

[0121] If so, a first risk score for the first sub-region is determined based on the comprehensive score of the target operation and the first region score in combination with the cross-operation.

[0122] The working principle of the above technical solution is: first, collect detailed information about the target operation, including the type of operation (such as maintenance, installation, cleaning, etc.), operation area, operation date, operation content, operation method and planned safety protection measures; these elements are the basis for evaluating the safety of the operation and determining the scope of the operation impact.

[0123] Based on the 3D model or the actual situation on site, the system determines the specific location of the target operation in the first area, including the boundaries and scope of the operation; this helps to understand how the operation will affect the surrounding area. Based on the type of operation, the content of the operation, and the possible risks, the system obtains or calculates the requirements for maintaining a safe distance from the target operation area. The safe distance is a key parameter to ensure that no unnecessary risks are caused to the surrounding area during the operation; combined with the specific location of the target operation in the first area and the safety distance requirements, the system divides one or more first sub-areas; these sub-areas represent areas that are affected by the target operation or require special attention. Based on multiple elements of the target operation, a risk assessment model is used to calculate the comprehensive score of the target operation. This score reflects the overall risk level of the operation, taking into account multiple risk factors and protective measures; check whether there are cross-operations in the same area that occur in time or space with the target operation. Cross-operations may increase risks because different operations may affect each other or conflict. If there is no cross-operation, the system directly calculates the first risk score of the first sub-area based on the comprehensive score of the target operation and the score of the first area; this score reflects the risk level of the sub-area under the influence of the target operation.

[0124] If there is cross-operation, the system needs to additionally consider the impact of the cross-operation. This may include assessing the risk of the cross-operation, determining the degree of impact of the cross-operation on the target operation, etc. Then, the system combines this information to calculate the first risk score for the first sub-area.

[0125] The core of the whole working principle is to determine the scope of influence and risk level of the operation by collecting and analyzing multiple elements of the target operation in detail, combined with the 3D model or the actual situation on site. Then, by dividing the sub-areas and calculating the risk score, accurate decision support is provided for safety management. This method helps to identify and prevent potential risks in advance, ensuring the safety and smooth progress of the operation process.

[0126] The effects of the above technical solutions are as follows: by collecting multiple elements of the target operation in detail, a more comprehensive understanding of the operation situation can be obtained, thereby more accurately conducting risk assessment and prediction; determining the specific location and safety distance of the operation area helps to ensure that no unnecessary risks or impacts are caused to the surrounding areas during the operation; based on the comprehensive score and risk score of the operation, a more accurate risk score can be obtained, and sufficient support and attention can be ensured for key areas and key operations; identifying and handling cross-operations helps prevent safety accidents caused by the mutual influence of different operations, thereby improving the overall safety of the operation process.

[0127] In some embodiments, the risk assessment model comprises:

[0128] Performing a first scoring on the elements of each target job to obtain a plurality of first scoring results;

[0129] According to the multiple first scoring results, a comprehensive score of the target task is obtained.

[0130] The working principle and effect of the above technical solution are as follows: First, the model needs to identify all the key elements included in the target operation. These elements may include personnel, equipment, environment, management and other aspects, each of which may have an impact on the safety and success rate of the operation; formulate scoring criteria for each element, which can be quantitative (such as the service life of the equipment, the training time of the personnel, etc.) or qualitative (such as the complexity of the operation, the uncertainty of the environment, etc.); score each element according to the defined scoring criteria; assign a weight value to each element according to the degree of influence of each element on the risk of the target operation. This weight value reflects the importance of the element in the risk assessment, and the weight values ​​of different elements may be different; multiply the first score of each element by its corresponding weight value to obtain a weighted score. Then add up the weighted scores of all elements to obtain the comprehensive score of the target operation; in order to make the comprehensive scores between different target operations comparable, the comprehensive score can be standardized and converted into a relative value. The results of the risk assessment are output to relevant personnel or systems so that they can make corresponding decisions or take corresponding measures based on the assessment results. At the same time, the model can also adjust and optimize the scoring criteria and weight values ​​according to actual work results and feedback to improve the accuracy and effectiveness of risk assessment.

[0131] Through this process, the risk assessment model can comprehensively and systematically evaluate the risk level of the target operation and provide decision support and guidance to relevant personnel.

[0132] In some embodiments, determining the first risk score of the first sub-region according to the comprehensive score of the target operation and the first score of the first region in combination with the cross-operation includes:

[0133] The first risk score is obtained in the following manner:

[0134]

[0135] Among them, F ik is the first risk score of the kth first sub-region of the i-th first region, C i is the first score of the i-th first region; T ik Y is the comprehensive score of the target task in the kth first sub-area of ​​the i-th first area; i The impact score of each cross operation in the first area of ​​ith, 0 <Y i <1; α, β, γ are weight coefficients; Z v is the comprehensive score of the vth cross-operation in the first area; T ik is the comprehensive score of the target operation; m is the number of cross-operations in the i-th first area.

[0136] The working principle of the above technical solution is: determine the first risk score of the first sub-area by comprehensively considering the comprehensive score of the target operation, the first score of the first area, the impact score of the cross-operation and the total number of cross-operations.

[0137] For the kth first sub-area in the ith first area, the comprehensive score of the target operation in the sub-area is first evaluated; this score involves evaluation of multiple aspects such as operation elements, operation environment, operation process, etc., and a comprehensive quantitative score is given based on these evaluation results.

[0138] Cross-operation refers to multiple operations carried out simultaneously in the same area, which may affect each other and increase risks. i It represents the risk impact score of cross-operation in the i-th first area. It is a value between 0 and 1, which is used to quantify the degree of increased risk caused by cross-operation. It is determined based on factors such as the type, frequency, and degree of mutual influence of cross-operation.

[0139] Z v is the comprehensive score of the vth cross-operation in the first area; and m refers to the number of cross-operations in the ith first area; the average comprehensive score of all cross-operations in the first area is calculated. This average value reflects the overall risk level of cross-operations and provides another important reference factor for risk scoring.

[0140] A comprehensive risk score is obtained by combining three factors (first area score, cross-operation impact and target operation comprehensive score) in a weighted manner to quantitatively assess the risk level of the first sub-area.

[0141] The calculated first risk score can be used as decision support information to guide relevant managers in making decisions on risk prevention and control, resource allocation, and job scheduling.

[0142] The effect of the above technical solution is that the formula comprehensively considers the overall risk of the first area, the comprehensive risk of the target operation, the impact of the cross-operation and the specific risk of each cross-operation, so as to more comprehensively evaluate the risk level of the first sub-area. By converting various risk factors into specific scores, the risk assessment results are more intuitive, easy to understand and compare. This helps managers to grasp the risk status more accurately and make more reasonable decisions.

[0143] In some embodiments, the S4 includes:

[0144] Obtaining the working environment information in the first area, including the gas properties and contents of the working environment information;

[0145] Determining whether the first area contains combustible gas and / or toxic gas;

[0146] If yes, then the corresponding gas concentration is compared with the corresponding gas concentration threshold in the basic operation library to obtain a first comparison result;

[0147] The gas concentration threshold comprises a first threshold and a second threshold;

[0148] Determine the environmental coefficient and / or issue an early warning based on the first comparison result; if the concentration threshold of any gas exceeds the corresponding first threshold and is less than the second threshold, issue a first early warning and perform ventilation;

[0149] If the concentration threshold of any gas exceeds the corresponding second threshold, a second warning is issued and personnel are evacuated; the warning may include sound alarms, light signals, and notifications sent to managers' mobile devices to remind them of the current environmental risks;

[0150] The environmental factor is:

[0151]

[0152] Among them, N tiC is the current concentration of the tth gas in the i-th first region; N ty is the first threshold value of the concentration of the tth gas.

[0153] The working principle of the above technical solution is as follows: first, collect the working environment information in the first area, which mainly includes the properties and contents of various gases. This information may be obtained through gas detectors, sensors or other monitoring equipment.

[0154] The collected gas information is analyzed to determine whether the first area contains combustible gas and / or toxic gas; this is based on the identification of gas properties in the basic operation library, and each gas has its own unique chemical and physical properties.

[0155] If flammable or toxic gases are detected, the system will compare the current concentration of these gases with the corresponding gas concentration thresholds in the basic operation library; the basic operation library is a pre-set database that contains the safe concentration thresholds of various gases in different operating environments. The result of the comparison is called the first comparison result. This result indicates whether the current gas concentration exceeds the safety threshold. Here, each gas has two concentration thresholds: the first threshold and the second threshold. The first threshold is usually a lower safety threshold, while the second threshold is a higher danger threshold.

[0156] If the environmental factor exceeds a preset warning threshold, or the concentration of any gas detected exceeds its safety threshold, the system will trigger the warning mechanism.

[0157] If the gas concentration exceeds the safety threshold, the system will calculate an environmental factor. This environmental factor is used to quantify the risk level of the current environment. The calculation formula is:

[0158] The formula calculates the relative difference between the current concentration and the threshold, and takes the maximum value of all detected gases as the environmental coefficient; if the concentration of all gases is below the safety threshold, the environmental coefficient is 0.

[0159] The effect of the above technical solution is: by real-time monitoring and comparing the gas concentration with the preset threshold, it is possible to quickly identify whether there is accumulation of flammable gas or toxic gas in the working environment, so that corresponding measures can be taken in time.

[0160] Setting the first threshold and the second threshold, as well as the corresponding first warning and second warning, ensures that different levels of response measures are taken according to different levels of gas concentration, making the warning more accurate and effective; through timely warning and response, the gas concentration can be prevented from exceeding the safe range, thereby reducing the risk of accidents such as fire, explosion or poisoning, and protecting the life safety and health of operators; through the automated monitoring and early warning system, the danger information can be quickly conveyed to the management personnel, reducing the time for manual monitoring and judgment, and improving the efficiency and accuracy of the response; providing a variety of early warning methods such as sound alarms, light signals, and sending notifications to the management personnel's mobile devices, ensuring the timely transmission and reception of warning information and enhancing the warning effect; when it is found that the concentration of dangerous gases exceeds the threshold, timely ventilation or evacuation and other response measures can be taken, reducing the time of interruption of operations due to the influence of dangerous gases and improving work efficiency.

[0161] In some embodiments, the S5 includes:

[0162] Divide the dangerous sub-areas according to the first risk score combined with multiple danger thresholds, display them through a three-dimensional system, and set safety gratings at the boundaries of the dangerous sub-areas;

[0163] The first risk score is adjusted according to the environmental factor. If the concentration of harmful or toxic gases in any first area is greater than the corresponding gas concentration threshold, the adjusted first risk score is:

[0164] Fad ik =(1+H i )×F ik

[0165] Among them, Fad ik is the adjusted first risk score of the kth sub-region of the ith first region; H i is the environmental coefficient in the first region of the ith region; F ik The first scoring risk score of the kth first sub-region of the i-th first region is calculated;

[0166] The hazardous sub-areas are adjusted according to the adjusted first risk score.

[0167] The working principle of the above technical solution is: first, according to the first risk score calculated in the previous step, combined with multiple preset danger thresholds, the first area is divided into different danger sub-areas; these danger sub-areas are displayed through a three-dimensional system (such as virtual reality, augmented reality or three-dimensional visualization software), so that managers can intuitively understand the risk status of each area.

[0168] A safety light barrier is set up at the boundary of a hazardous sub-area. This is a physical or virtual boundary marker that alerts personnel to the risks in the area and may trigger an alarm or prevent unauthorized personnel from entering.

[0169] When harmful or toxic gas is detected, an environmental coefficient is calculated based on the current concentration of the gas and the corresponding first threshold value. The environmental coefficient reflects the relative difference between the current gas concentration and the first threshold value and is used to quantify the increase in environmental risk.

[0170] If the concentration of harmful or toxic gas in any first area is greater than the corresponding gas concentration threshold (whether the first threshold or the second threshold), the first risk score is adjusted according to the environmental factor. The adjusted first risk score is the product of the original risk score and the environmental factor plus the original risk score itself. This adjustment method makes the risk score of the corresponding area increase accordingly when the environmental risk increases.

[0171] Based on the adjusted first risk score, the system re-evaluates the division of dangerous sub-areas; if the risk score of a sub-area exceeds the new danger threshold, it may be reclassified as a sub-area with a higher risk; finally, the system updates the display in the 3D system to reflect the new division of dangerous sub-areas and the corresponding risk score. This helps managers understand the risk status of the working environment in real time and make corresponding decisions and countermeasures accordingly.

[0172] In this way, step S5 can achieve dynamic assessment and monitoring of working environment risks, ensuring that the division of dangerous sub-areas is always consistent with the actual situation, thereby improving the safety and management efficiency of the working environment.

[0173] The effect of the above technical solution is: by displaying the dangerous sub-areas through the three-dimensional system, managers can intuitively understand the risk status of each area in the working environment, which is convenient for making decisions quickly. Adjusting the first risk score in real time according to the changes in the environmental coefficient can dynamically reflect the risk changes in the working environment and ensure the accuracy and timeliness of the risk assessment; setting a safety grating at the boundary of the dangerous sub-area, when a person approaches or enters the dangerous area, it can trigger an early warning in time to remind the person to pay attention to safety; according to the adjusted first risk score, the system can flexibly adjust the division of dangerous sub-areas to ensure that the division of dangerous areas is always consistent with the actual situation. Through automated risk assessment and sub-area adjustment, the need for manual intervention is reduced and the efficiency of safety management is improved. Through real-time risk assessment and early warning mechanisms, potential safety risks can be discovered and responded to in a timely manner, thereby effectively reducing the possibility of accidents and ensuring the safety of operators. Based on the adjustment of risk scores, security resources can be reasonably allocated, such as adding security monitoring equipment, strengthening patrols, etc., to ensure that high-risk areas receive more attention and protection; intuitive three-dimensional display and dynamic risk assessment provide managers with rich information support, which helps to make quick and accurate decisions and improve management efficiency; by continuously collecting and analyzing operating environment data, the system can continuously optimize risk assessment models and sub-area division strategies to improve the accuracy and reliability of risk assessment.
