[0021] In order to improve the verification efficiency of on-site equipment, the present application provides a verification method for on-site equipment. The verification method for on-site equipment provided by the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Please refer to the attached Figure 1 , Figure 1 A flowchart of a method for verifying an on-site device provided in an embodiment of the present application. The method may include the following steps: Step S101: In response to a verification request for verifying an on-site device, equipment information of the on-site device is obtained, the equipment information including a probabilistic safety assessment report, a three-dimensional layout diagram of the equipment, and a system design manual.

[0023] In this application, in response to a verification request for verification of an on-site device, comprehensive and detailed device information related to the on-site device is first obtained. This information is the basis of the verification process and helps to evaluate whether the safety, functionality, maintainability, and human-computer interaction of the device meet the expected standards. The mentioned device information mainly includes probabilistic safety assessment reports, three-dimensional equipment layout drawings, and system design manuals, and may also include equipment operating instructions.

[0024] It should be noted that the probabilistic safety assessment report usually includes a quantitative assessment of the probability of equipment failure, the severity of the consequences of the incident, and the overall safety of the system.

[0025] The 3D layout of equipment is a drawing that uses 3D modeling technology to show the location, layout and relationship of equipment in a specific space. It not only provides basic information such as the physical size, installation location and orientation of the equipment, but also shows the relative position and connection relationship between the equipment and other systems and structures.

[0026] The system design manual describes the system's functions, system design, descriptions of each local device involved in the system, and general operating principles.

[0027] The equipment instruction manual is a guiding document that introduces the equipment functions, operating methods, safety precautions, maintenance, etc. to users.

[0028] Step S102: Based on the probabilistic safety assessment report, determine the target on-site equipment from various on-site equipment.

[0029] To ensure safety and reliability, rigorous verification of on-site equipment is required, but considering the design iteration time, design schedule and limited human resources, target on-site equipment with higher risks can be identified and prioritized.

[0030] Firstly, based on the probabilistic safety assessment report, the risk importance of each local equipment is evaluated using the fault tree and event tree to obtain the risk importance of each local equipment. Then, based on the risk importance of each local equipment, the local equipment is determined as the target local equipment that needs priority attention and processing.

[0031] Step S103: Based on the equipment three-dimensional layout diagram, the system design manual and the preset human factors engineering design guidelines, the target on-site equipment is verified to obtain the verification result.

[0032] It should be noted that the preset human factors engineering design guidelines include the first human factors engineering verification indicator, the second human factors engineering verification indicator, the third human factors engineering verification indicator, the fourth human factors engineering verification indicator, the fifth human factors engineering verification indicator, the sixth human factors engineering verification indicator, the seventh human factors engineering verification indicator and the eighth human factors engineering verification indicator. The first human factors engineering verification indicator is used to indicate accessibility, the second human factors engineering verification indicator is used to indicate operability, the third human factors engineering verification indicator is used to indicate the first human factors trap, and the fourth human factors engineering verification indicator is used to indicate the working environment; the fifth human factors engineering verification indicator is used to indicate hazard protection, the sixth human factors engineering verification indicator is used to indicate the isolability of equipment, the seventh human factors engineering verification indicator is used to indicate human capabilities, and the eighth human factors engineering verification indicator is used to indicate the second human factors trap. The verification results include the first verification results and the second verification results, among which there are target on-site equipment that has passed the verification and target on-site equipment that has not passed the verification.

[0033] In this application, based on the system design manual, the three-dimensional layout of the equipment, the first ergonomics verification index, the second ergonomics verification index and the third ergonomics verification index, the three-dimensional design software is used to verify the target on-site equipment to obtain the first verification result. Based on the system design manual, the fourth ergonomics verification index, the fifth ergonomics verification index, the sixth ergonomics verification index, the seventh ergonomics verification index and the eighth ergonomics verification index, the digital verification platform is used to verify the target on-site equipment to obtain the second verification result.

[0034] Among them, the system design manual includes the system process flow, plant, floor, room, equipment type, equipment function, operation requirements, etc. When verifying the on-site equipment, you first need to know what type of equipment it is, and verify whether its position in the 3D design software is correct according to the system process flow, plant, floor, room, etc. where the equipment is located as specified in the system design manual.

[0035] Use 3D design software to open the 3D layout drawing, and according to the system design manual, the first ergonomics verification index, the second ergonomics verification index and the third ergonomics verification index, verify the target on-site equipment from the three ergonomics aspects of "accessibility", "operability" and "ergonomics trap (usual habit one)" to obtain the first verification result.

[0036] Specifically, use the "measurement" function of the 3D design software and the personnel observation method (the observation method is a method in which researchers use their own senses and auxiliary tools to directly observe the research object according to certain research purposes, research outlines and observation tables to obtain data) to verify whether the accessibility of the on-site equipment meets the verification index requirements: use the "measurement" function to measure whether the passageway in the room where the equipment is located is wide and deep enough to accommodate the necessary personnel and equipment / tools, whether the size of the inspection port meets the requirements, whether the observation port is large enough and can be observed by both eyes, whether the height from the ground to the grasped object is too high, whether it meets the requirements of the single-person passage width and the double-person passage width, whether the equipment is inaccessible, whether there is no need to overextend the body or tiptoe when working on-site, whether it is necessary to carry heavy objects over long distances, etc.; use the observation method (if necessary, in combination with the equipment / component instruction manual) to verify whether there are obstacles on the path, whether there is permanent or temporary equipment obstruction to the on-site operator's line of sight, whether the operator needs to observe the display from an inclined direction, whether the on-site operator can see all task-related information, and whether the personnel passage should avoid dangerous areas.

[0037] Use the "measurement" function of the 3D design software and the personnel observation method to verify whether the operability of the on-site equipment meets the verification index requirements: whether the operating position is too high or too low, whether the equipment layout has enough operating and maintenance space, the correlation between the equipment, whether the maintenance affects other equipment, whether the distance of the on-site working environment is large enough to prevent adjacent controllers from being triggered by mistake, etc.; use the observation method combined with the equipment / component instruction manual to verify, observe whether the maintenance of such equipment requires disassembly / is easy to disassemble, whether the designed anti-accidental collision facilities require auxiliary equipment or special tools, etc.

[0038] Use 3D design software and personnel observation method to verify whether the human factors trap (usual habit 1) of the on-site equipment meets the verification index requirements: Use the personnel observation method on the 3D design software to verify: whether the operation direction of the equipment layout conforms to the usual habits (for example, the inverted installation of the valve does not conform to the usual habits of the operation direction), whether the working position conforms to the usual habits, etc. Among them, the usual habits 1 include the operation direction and the working position.

[0039] A digital verification platform was used to verify the target on-site equipment from five human factors engineering aspects, namely, "working environment", "hazard protection", "equipment isolability", "human capabilities" and "human traps (logos, colors, alarms and common habits 2)" according to the system design manual, the fourth human factors engineering verification indicator, the fifth human factors engineering verification indicator, the sixth human factors engineering verification indicator, the seventh human factors engineering verification indicator and the eighth human factors engineering verification indicator, to obtain the second verification result.

[0040] Specifically, the working environment includes the climate environment, visual environment and auditory environment. Working environment: whether maintenance personnel may be exposed to toxic / harmful, over-cold / over-heated substances, working area temperature, working area humidity, and air flow speed in the working area; Visual environment: whether the illumination in the working area meets the work requirements, whether there are additional light sources, and whether the emergency lighting system provides appropriate light in all operating areas; Auditory environment: whether the fixed background noise level in the on-site working area meets the requirements, and whether corresponding protection is provided in areas where it exceeds the requirements.

[0041] Hazard protection includes general hazard protection and radiation protection. General hazard protection includes: whether the equipment has irregular protrusions, whether the operating object has a dangerous energy level, whether it is placed in a position that personnel cannot touch, whether the equipment may cause danger to personnel when the operator performs equipment maintenance according to the procedures, etc.; Radiation protection includes: whether working in a radiation environment can be avoided or minimized, whether rapid shielding devices are provided for working in high radiation fields, as well as the installation space and transportation channels for the shielding devices, etc.

[0042] Isolatability of equipment: whether reliable isolation means are provided for maintenance, whether means for draining residual media or energy in the working area are provided, whether the isolation boundary affects the operation of key functions of the system, etc.

[0043] Human capabilities: whether the operation requires unusual / extreme body postures, whether frequent or sustained physical effort is required, whether the object can be held close to the center of the body by the operator (pushing, lifting, pulling, supporting, or holding an object in an uncomfortable / unsustainable posture), whether there are special skill requirements for operating this type of equipment, etc.

[0044] Human traps include signs, colors, alarms, and common habits 2. Signs: whether there are unclear signs / insufficient information, whether the signs are clear / unambiguous, whether the status of the equipment (switch, locked) can be easily distinguished, whether the location of the signs / indications can be easily seen, whether there are warning signs for dangers, whether the functional grouping of the equipment can be accurately marked, etc.; Colors: colors are not easy to confuse, the color coding system should be used consistently on all controllers and displays, the same color cannot represent contradictory meanings, and different meanings cannot use the same color, etc.; Alarms: whether alarm signals are set for necessary information, whether there are nuisance alarms, etc.; Common habits 2: whether it conforms to traditional habits and conventional habits (such as valve indications, the use of color codes should conform to conventional habits, such as: valve indication direction perpendicular to the pipeline flow direction is closed, parallel to the pipeline flow direction is open, etc.).

[0045] In summary, the present application provides a verification method for on-site equipment. In response to a verification request for verification of on-site equipment, the equipment information of the on-site equipment is obtained, and the equipment information includes a probabilistic safety evaluation report, a three-dimensional layout diagram of the equipment, and a system design manual. By using the probabilistic safety evaluation report as the basis for screening target on-site equipment, it is possible to scientifically identify which equipment has the greatest impact on overall safety in potential accidents or abnormal situations. Targeted verification enables resources (such as time, manpower, and funds) to be allocated more effectively, which is beneficial to the efficiency of the overall verification work. Verification is carried out in combination with the three-dimensional layout diagram of the equipment, the system design manual, and the preset human factors engineering design guidelines. It not only focuses on the physical characteristics and technical specifications of the equipment itself, but also fully considers the challenges and limitations that operators may encounter in actual operations, and the verification of on-site equipment is more complete.

[0046] Furthermore, based on the above method, the following steps may be included: Step S104: The target on-site equipment that has not passed the verification is regarded as a human factor deviation item, and the human factor deviation items are graded to form a list of human factor deviation items.

[0047] In this application, the verification process can accurately identify the human deviation items in the design, that is, the design elements that may cause human errors or increase the complexity of operation. The equipment information of the human deviation items, the human factors engineering design guidelines violated by the human deviation items, and the priority of the human deviation items are obtained, and the above-obtained contents are formed into a list of human deviation items.

[0048] Among them, for the nuclear industry, the priority of human error items can be divided into Level I, Level II and Level III. Level I involves safety-level functions; Level II is non-safety-level functions, and human error items directly lead to the inability to perform a certain task; Level III, non-safety-level functions, human error items can be compensated by existing information.

[0049] Step S105: Return the list of human factors deviation items to the designer of the on-site equipment.

[0050] In this application, after receiving the list of human error items, the designers conducted an in-depth analysis of the list of human error items, found out the design deficiencies, and took corresponding improvement measures to optimize the corresponding on-site equipment to form a closed loop. A closed-loop mechanism from design to verification to feedback was established to identify and correct deviations, which helps to continuously improve product design, continuously improve product safety and reliability, and further reduce the risk of accidents caused by human errors.

[0051] On the basis of the above-mentioned embodiment disclosed in the present application, in another embodiment of the present application, a specific implementation method of determining a target on-site device from various on-site devices based on a probabilistic safety evaluation report is described in detail.

[0052] As an example of an implementation method, please see the attached Figure 2 , is a schematic diagram of a process of determining a target on-site device from various on-site devices based on a probabilistic safety evaluation report disclosed in this application. The method may include the following steps: Step S201: Based on the probabilistic safety assessment report, the risk importance of each on-site equipment is evaluated using the fault tree and event tree to obtain the risk importance, risk increase value and risk reduction value of each on-site equipment.

[0053] It should be noted that risk importance can include risk importance, risk increase value and risk reduction value. Risk importance: measures the direct contribution of equipment failure to the overall risk of the system, reflecting the probability of equipment failure and the severity of the consequences that may result from failure. Risk increase value: evaluates the degree to which the overall risk of the system increases when the probability of equipment-related operational errors increases, reflecting the risk amplification effect of the equipment in the context of human error. Risk reduction value: evaluates the degree to which the overall risk of the system is reduced when operational errors are reduced by improving equipment design or operating procedures, reflecting the risk reduction effect that can be brought about by reducing human errors by improving equipment design.

[0054] In this application, the fault tree can identify and analyze various failure modes and their logical relationships that lead to equipment failure or accidents. Specifically, first determine the undesirable risk events as "top events", then analyze the various direct factors that lead to the "top events" as "intermediate events", and then conduct in-depth recursive analysis of the causes of the intermediate events until the bottom-level factors that do not need to be investigated are "basic events or bottom events", and finally use logic gate symbols to connect the upper and lower events to form an inverted tree-like logical relationship diagram, namely the fault tree diagram. Through fault tree analysis, the contribution of each basic event to the probability of occurrence of the top event can be quantitatively evaluated, thereby obtaining the risk importance.

[0055] Event tree analysis can simulate the complete sequence from equipment failure to accident occurrence and evaluate the consequences of accidents in different scenarios. Specifically, it starts with equipment failure (or initial event), alternately considers the two possibilities of success and failure, and then uses these two possibilities as new initial events, continues to analyze until the final result, and finally forms an inductive logic tree diagram to show the consequences under different development paths. Through event tree analysis, the consequences of accidents under different combinations of operating errors or equipment failures can be evaluated, thereby obtaining risk increase and risk reduction values.

[0056] Step S202: For each on-site equipment, determine whether the risk importance of the on-site equipment is not less than the preset risk importance criterion value, whether the risk increase value of the on-site equipment is not less than the preset risk increase value criterion value, and whether the risk reduction value of the on-site equipment is not less than the preset risk reduction value criterion value.

[0057] In this application, the preset guideline values ​​are usually determined based on a combination of factors such as safety requirements, industry standards and historical experience.

[0058] For ease of understanding, an example is given below: For a large nuclear power plant, the risk importance criterion value, risk increase value criterion value, and risk reduction value criterion value are used as indicators of the safety and reliability of the nuclear power plant. The risk importance criterion value is used to evaluate the contribution of each on-site equipment to the overall risk of the nuclear power plant. The risk importance criterion value can be 1×10^-3. The risk importance criterion value is used to measure the degree to which the overall risk of the nuclear power plant increases when the probability of human action errors related to a certain on-site equipment increases to 1. The risk increase value criterion value can be 2. The risk reduction value criterion value is used to measure the degree to which the overall risk of the nuclear power plant is reduced when human action errors related to a certain on-site equipment are completely avoided (probability is 0). The risk reduction value criterion value can be 1.1.

[0059] Step S203: If the risk importance of the on-site equipment is not less than the preset risk importance criterion value, the risk increase value of the on-site equipment is not less than the preset risk increase value criterion value, or the risk reduction value of the on-site equipment is not less than the preset risk reduction value criterion value, then the on-site equipment is determined to be the target on-site equipment.

[0060] In the present application, when at least one of the risk importance, the increased risk value and the risk reduction value of the on-site equipment does not meet the requirements, the on-site equipment can be determined as the target on-site equipment.

[0061] For ease of understanding, an example is given below: the risk importance of the "electric valve" is 1.5×10^-3, the risk increase value is 3, and the risk reduction value is 1.2. This electric valve is determined as the target on-site equipment. Therefore, in the subsequent verification, it is given priority to be verified and optimized to ensure that it can be reliably used by the operator in an emergency, thereby effectively reducing the overall risk of the nuclear power plant.

[0062] In summary, the embodiments of the present application disclose a probabilistic safety assessment report, which can clarify which equipment or equipment combinations have the greatest impact on the overall risk of the system by evaluating the risk importance of on-site equipment, which helps enterprises quickly locate high-risk areas. The risk increase value assessment can reveal which equipment failures increase system risk most significantly, which helps enterprises identify key weak links. The risk reduction value assessment can reveal which equipment improvements or upgrades are most effective in reducing system risk, which helps enterprises identify priority improvement items. By comparing these three risk importances with the preset importance criterion values, it is possible to objectively determine which equipment's risk contribution exceeds an acceptable range, thereby accurately locating high-risk equipment.
