Obviously, the drawings described below are only some embodiments recorded in the present invention. For ordinary technicians in this field, other drawings can also be obtained based on these drawings.

[0027] Figure 1 The system module diagram of the present invention is DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figure 1 As shown, the present invention is an accident prevention control system in enterprise safety consulting services, including a source extraction module, a standard specification module, a risk identification module, and an expected control module;

[0030] The information source extraction module is used to collect engineering risk information and employee review information, and pre-process the engineering risk information and employee review information before transmitting them to the standard specification module;

[0031] The standard specification module is used to conduct standardized evaluation of the operating procedures in the safety consultation process and verify the differences between actual operations and standard operations;

[0032] The risk identification module is used to conduct risk assessment on risk points in security consulting services and establish a risk assessment model to grade the risk level;

[0033] The expected control module is used to perform expected risk control management based on risk levels.

[0034] In the enterprise safety consulting service, it is crucial to carry out accident prevention and control. Preventive management can effectively reduce the occurrence of accidents in the workplace, protect the lives and health of employees, and enhance employees' sense of security and job satisfaction. Engineering inspection work usually involves complex instruments and equipment, high-altitude operations, chemical handling and other high-risk operations. Through effective accident prevention and control, the occurrence of work-related injuries and occupational diseases can be reduced, and the health and safety of employees can be guaranteed; accidents often lead to direct economic losses, such as medical expenses, compensation costs, and production stagnation. Through preventive management, these unnecessary expenses can be reduced and the economic interests of the enterprise can be protected. A safe working environment can reduce the shutdown and production interruption caused by accidents, ensure the continuity and stability of the inspection work, and thus improve the overall work efficiency and productivity. Accidents often bring direct and indirect economic losses, including medical expenses, compensation costs, equipment maintenance costs, and economic losses caused by production delays. Through effective preventive control measures, these economic losses can be greatly reduced. A safe working environment helps to improve the work efficiency of employees, reduce shutdowns and equipment damage caused by accidents, thereby improving the production efficiency and capacity of enterprises. At the same time, effective safety management and low accident rates can enable enterprises to obtain lower insurance premiums and save operating costs. All regions have strict legal and regulatory requirements for workplace safety. Accident prevention management can help companies comply with these regulations and avoid legal sanctions and fines for violations. The company's safety record will affect its public image and market competitiveness. Good accident prevention management can enhance the company's sense of social responsibility and reputation, enhance the trust of customers and partners, and further expand market opportunities. A corporate culture that emphasizes safety can improve employee morale, enhance team cohesion, reduce employee turnover, and attract and retain outstanding talents. Safety is the cornerstone of a company's long-term development. Through systematic accident prevention management, companies can establish a scientific safety management system to support their long-term healthy and sustainable development.

[0035] In the enterprise safety consulting service, the source extraction module of the accident prevention and control system is used to collect engineering risk information and employee review information, and pre-process the engineering risk information and employee review information before transmitting them to the standard specification module;

[0036] Engineering risk information refers to the safety hazard elements of the work site obtained through the enterprise safety consulting service process, including physical risks, chemical risks and biological risks. Physical risks include high-altitude operations and mechanical equipment factors, chemical risks include harmful chemicals, and biological risks include toxic gases. Through the analysis of historical safety risk data and existing accident and hazard records, the risk sources are extracted and identified, and the risk level is evaluated by combining fault tree analysis and event tree analysis.

[0037] Fault tree analysis is a top-down deductive analysis method that determines the potential risk sources and critical failure paths of the system by analyzing various basic events in the system that may lead to specific top events.

[0038] It should be noted that the top event is a system failure or accident, and the basic events include component failure or operational error.

[0039] The analysis process is to determine the top event to be analyzed. Starting from the top event, it is decomposed layer by layer to identify the direct and indirect causes of the top event. The basic events are connected using logic gates to form a tree structure. The contribution of each basic event to the top event is determined through qualitative or quantitative analysis, and the basic event and path that has the greatest impact on the top event are found.

[0040] For logic gates such as AND gates and OR gates, common quantitative analysis methods include minimum cut sets and failure probability calculation.

[0041] The employee review information is the length of time employees entering the work site receive in safety risk training courses. Through safety risk training for employees, employees can identify potential risks in their work, take preventive measures, and reduce the occurrence of accidents. If employees understand the correct operating procedures and protective measures, they can effectively reduce injuries and occupational diseases at work. At the same time, accident prevention can avoid production interruptions caused by accidents and ensure the continuity and stability of the production process. After employees master safe operating skills, they can improve work efficiency and quality, and reduce production delays, customer churn, and reputation damage caused by accidents. Through training, employees understand emergency plans and emergency handling procedures, improve their emergency response capabilities in emergencies, and reduce the impact of accidents. The length of time employees receive education in safety risk training courses is directly related to the degree of operational safety risk. The more fully they understand safety risks, the lower the probability of non-procedural operations and the higher the level of safety.

[0042] The standard specification module is used to conduct standardized evaluation of the operating procedures in the safety consultation process and verify the differences between actual operations and standard operations;

[0043] Check whether the company has formulated complete operating procedures, including all testing and operating steps, ensure that there are detailed guidance documents for each link, confirm whether the company has established a systematic and standardized document system, covering operating procedures, maintenance procedures, safety manuals, etc., evaluate the consistency between actual operations and standard procedures, ensure that all employees strictly follow standardized procedures when performing operations, regularly evaluate the implementation of procedures through internal audits and third-party inspections, discover and correct deviations, measure the proportion of employees who have received training on operating procedures and standardized procedures, including training for new employees and regular training for in-service employees, evaluate the effectiveness of training through examinations, practical exercises, etc., and ensure that employees have mastered and can correctly implement standardized operating procedures;

[0044] During the actual operation, check the record and traceability system in the operation process to ensure that each operation step has detailed records and can be traced back to the specific executor and operation time. Determine and monitor key operation links and control points to ensure that key links are strictly implemented in accordance with standardized procedures. Evaluate whether the operation procedures include identification and assessment of potential risks, ensure that all operation steps take into account possible safety risks, check the implementation of risk control measures, and ensure that each risk control point is effectively managed and monitored.

[0045] The risk identification module is used to conduct risk assessment on risk points in security consulting services and establish a risk assessment model to grade the risk level;

[0046] The risk assessment model is constructed as follows:

[0047] The calibrated height of high-altitude work is Wh, the actual maintenance cycle of mechanical equipment is Mc, the saturated vapor concentration of harmful chemicals at 0°C is Sa, the predicted environmental concentration of toxic gases is Pe, the duration of employee safety risk training courses is Ed, and the guidance probability of combining fault tree analysis and event tree analysis is Gp. The calculation expression of the risk index Re of the risk assessment model is: In the formula, e is the number of the risk index oriented to different accident results, and e= { 1,2,3…Q } , Nu is the number of operating staff, α and β are and The weight coefficient of , and α and β are both positive numbers.

[0048] It should be noted that predicted environmental concentration refers to the concentration of chemical substances in specific environmental media predicted by models during the environmental risk assessment process based on factors such as the release characteristics, usage patterns, and environmental behaviors of chemical substances. Specific environmental media such as water, soil, and air can be obtained by using mathematical models or actual environmental measurements. Mathematical model calculations use mathematical equations to describe the behavior of chemical substances in the environment, including processes such as diffusion, adsorption, and degradation. Actual environmental measurements directly use the measured concentrations from environmental monitoring data.

[0049] Comprehensively evaluate the risk index oriented to different accident results and calculate the composite safety risk index Cr. The calculation method is: In the formula, Q is the total number of accident result types, Re is the risk index, e is the number of the risk index oriented to different accident results, and e= { 1,2,3…Q }, Cy is the security consulting service cycle, a first risk threshold and a second risk threshold are preset, and the first risk threshold is less than the second risk threshold. When the calculated composite security risk index is less than the first risk threshold, the security level is rated as level one; when the calculated composite security risk index is greater than or equal to the first risk threshold and less than or equal to the second risk threshold, the security level is rated as level two; when the calculated composite security risk index is greater than the second risk threshold, the security risk level is rated as level three.

[0050] The expected control module is used to manage expected risk control according to risk levels;

[0051] If the safety risk level is level 1, there is a risk of causing minor consequences, including minor personal injury and minor equipment damage. All minor risk events should be recorded and reported, and the operating procedures should be optimized based on the analysis results of the records and reports.

[0052] If the safety risk level is level 2, there is a risk of moderate consequences, including personal injury and equipment failure within a relatively small range. A detailed emergency plan should be developed, an emergency response team should be established, and emergency rescue should be organized in a timely manner.

[0053] If the safety risk level is level three, there is a danger of serious consequences, including serious personal injury, equipment damage, and environmental pollution. Real-time surveillance cameras are used to continuously monitor high-risk areas and operations, abnormal situations are discovered and handled in a timely manner, and risk audits and assessments are conducted regularly.

[0054] Embodiment 2: In a specific embodiment, the risk state is evaluated by using fault tree analysis, with serious personal injury occurring during the safety detection process as the top event, and logic gates are used to connect the top event with each basic event, and the logical relationship is:

[0055] A1 high altitude fall

[0056] B1 No safety protection equipment is used (AND gate)

[0057] C1 Not wearing a seat belt

[0058] C2 has no guardrail

[0059] B2 protection device failure (AND gate)

[0060] C3 seat belt aging or damage

[0061] C4 guardrail is loose or damaged

[0062] A2 Electric shock accident

[0063] B3 device leakage (AND gate)

[0064] C5 Improper equipment maintenance

[0065] C6 Insulation material aging

[0066] B4 does not operate as specified (AND gate)

[0067] C7 The operator did not operate according to the specification

[0068] C8 lacks operational training

[0069] A3 Chemical Leak

[0070] B5 Improper storage of chemicals (AND gate)

[0071] C9 storage container damaged

[0072] C10 Chemical storage environment is not compliant

[0073] B6 operation error (AND gate)

[0074] C11 Operator misoperation

[0075] C12 Not wearing protective equipment

[0076] A4 Mechanical damage

[0077] B7 device failure (AND gate)

[0078] C13 Equipment aging

[0079] C14 maintenance is not timely

[0080] B8 device failure (AND gate)

[0081] C15 Operators are unskilled

[0082] C16 lacks operating procedures

[0083] Conduct qualitative and quantitative analysis on each basic event to assess its probability of occurrence and contribution to the top event. Qualitative analysis is to find the key path in each branch and determine the main risk sources and weak links. Quantitative analysis is to assign a probability value to each basic event, calculate the overall probability of each branch, and determine the overall risk level of the top event.

[0084] Use the minimum cut set method to find the minimum set of events that lead to the top event and calculate the probability of occurrence of the minimum set of events.

[0085] Event tree analysis is a bottom-up inductive analysis method that evaluates the potential risks and accident consequences of the system by analyzing the possible development paths and consequences after the initial event. The process of event tree analysis is as follows:

[0086] Determine the initial event for analysis. The initial event is usually a system failure or external event with failure potential. Starting from the initial event, gradually analyze its possible subsequent events and system responses. Each branch represents a possible path or event development process. Assign a probability of occurrence to each branch, calculate the probability of occurrence of each final event, evaluate the consequences and impact of each final event, and determine the most likely and most serious accident path.

[0087] Combine fault tree analysis and event tree analysis to determine the final accident result. Guided by the accident result, build the development path through the preset initial events, use the minimum cut set method to calculate the probability of the determined accident result, and define the probability of the accident result combined with fault tree analysis and event tree analysis as the guided probability.

[0088] This application visualizes the probability of risk events by combining fault tree analysis and event tree analysis, establishes a risk assessment model for potential accident risks, evaluates and judges different types of accident risks, and conducts a comprehensive analysis based on human factors and non-human factors in the safety operation process. It can effectively solve potential risk problems in enterprise safety consulting services, effectively classify the risk levels of different safety issues, reduce hidden crises in enterprise safety consulting, and improve the effectiveness of risk control.
