[0030] See also Figure 1 , Figure 1 A method for checking human factors compliance of equipment layout in a nuclear power plant provided in one embodiment of the present invention includes steps S100 to S400.

[0031] Step S100: Obtain attribute information of each device in the nuclear power plant according to the three-dimensional model of the nuclear power plant. There are many devices in the nuclear power plant, and the three-dimensional model will be designed in advance during the design process. The three-dimensional model is a technology that uses three-dimensional geometric shapes to represent objects. It is widely used in engineering, architecture, design, manufacturing and other fields. The three-dimensional model generally contains the geometric size, position, direction and posture, material properties, connection and assembly information, performance parameters, safety characteristics and other information of the equipment. Therefore, the attribute information of each device can be obtained through the three-dimensional model. The attribute information is mainly used for the subsequent classification of the equipment, and the appropriate attribute information can be selected according to the preset classification rules.

[0032] Step S200: Get the category of each device according to the attribute information of each device and the preset classification rules. The preset classification rules define the categories of devices and the device attribute information corresponding to each category from the beginning. After the definition, the device can be classified according to the attribute information of the device obtained in step S100.

[0033] See also Figure 2In a specific embodiment of the present invention, step S200 includes: S201, preliminarily classifying each device according to the attribute information of each device and the preset device type; S202, secondary classifying each device according to the attribute information of each device and the preset device characteristics. Taking common devices as an example, in step S201, for example, the devices can be divided into instruments, valves, panels and cabinets, etc. In addition, there can be other classifications, which can be set according to the actual usage scenarios. For step S202, the following uses instruments and valves as examples to illustrate how to perform secondary classification.

[0034] Instruments are devices used to measure, monitor and control physical quantities (such as temperature, pressure, flow, liquid level, etc.) in industrial processes. They can be simple mechanical devices or complex electronic or computer systems. Instruments can be secondary classified according to the way the readings are read, resulting in local display instruments and remote transmission instruments. Local display instruments are installed directly near the equipment and are used to display the measured values ​​on site, such as pressure gauges, thermometers, etc. In addition to normal maintenance work such as instrument calibration, these instruments also involve on-site readings during normal operation, so it is necessary to pay attention to the needs of instrument readings. The measured values ​​of remote transmission instruments are transmitted to remote locations such as control rooms or monitoring centers through electrical or wireless signals for recording, analysis or control. These instruments do not need to be read on site, and their readings are displayed remotely such as in the main control room, so the main focus is on instrument maintenance requirements.

[0035] A valve is a device used to control the flow of fluids (such as liquids, gases, and steam). It can open, close, or regulate the flow of fluids to meet the needs of industrial processes. Valves can be secondary classified according to the way they are operated, resulting in manual valves and non-manual valves. Manual valves control the opening and closing of valves through manual operation (such as a wheel, lever, or handle). In addition to normal maintenance work, such valves also involve manual operation during normal operation, so the operability of manual valves needs to be considered. Non-manual valves control the opening and closing of valves through electric, pneumatic, hydraulic, or other automated means. Such equipment is remotely operated in the main control room or other places during normal operation, and does not require manual operation on site. It mainly involves valve maintenance work, so the main focus is on the maintenance requirements of valves.

[0036] Panel cabinets, also known as distribution cabinets, control cabinets or switch cabinets, are closed metal boxes used to install, protect and maintain electrical equipment and components. They are usually used in power distribution systems, control systems and automation systems. For panel cabinets, secondary classification is not required.

[0037] In this embodiment, the preset equipment types and preset equipment features are preset classification rules, which are set in advance. The above-mentioned preliminary classification (instruments, valves, panels and cabinets) and secondary classification are only for illustration. The actual classification is much more complicated, and more detailed classifications can be performed as needed. When specifying the classification rules, it should be noted that the classification should be combined with the ergonomic requirements of the equipment. The original intention of classification is to put the equipment with the same ergonomic requirements in the same group so that the ergonomic compliance check can be automatically performed with the same tool later.

[0038] Step S300, according to the category of each device and the preset human factors engineering criteria library, obtain the human factors engineering requirements of each device. The human factors engineering criteria library is usually preset based on the theory and practice of human factors engineering, as well as the standards and specifications of a specific industry. These criteria libraries contain a series of design principles and standards for guiding the design of products, equipment or environments to ensure that they can adapt to the body size, ability, behavior and psychological characteristics of human users. In this step, the human factors engineering criteria library is the mapping relationship between the category of the device and the human factors engineering requirements. With this mapping relationship, the corresponding human factors engineering requirements can be obtained according to the category of the device.

[0039] In the plan for human factors compliance inspection of nuclear power plant equipment layout, the preset human factors engineering criteria library may include the following aspects: (1) Human size and ability: Consider the operator's body size, strength, flexibility, etc. to ensure that the location, height and operation method of the equipment are suitable for most operators; (2) Vision and perception: Ensure that the display instruments, indicator lights and control buttons on the equipment are easy to identify and read, while considering factors such as light, color and contrast; (3) Operation and control: The operation method of the equipment should be intuitive and easy to understand, and the location of control buttons and switches should be convenient for operation to reduce the possibility of operating errors; (4) Repair and maintenance: Ensure that there is sufficient space and conditions for operation when the equipment needs repair or maintenance, reducing repair time and cost; (5) Safety and health: The design should take into account the safety of the operator to avoid accidents or occupational diseases caused by improper design; (6) Environmental factors: Consider the special environmental conditions of the nuclear power plant, such as radiation, temperature, humidity, etc., and ensure that the equipment layout meets these environmental requirements.

[0040] In actual applications, human factors engineering criteria libraries may be customized and adjusted according to different application scenarios and requirements to ensure that they can meet the specific requirements of a specific project or environment. In the human factors compliance inspection platform for nuclear power plant equipment layout, these criteria libraries will be used to guide the operation of automatic inspection tools to ensure the human factors compliance of equipment layout.

[0041] Each type of equipment corresponds to multiple ergonomic requirements. If an automatic inspection tool is configured for each ergonomic requirement of each type of equipment, then a lot of automatic inspection tools need to be set up. In a specific embodiment of the present invention, step S300 includes: according to the category of each equipment and the preset ergonomic criteria library, obtaining the general ergonomic requirements and special ergonomic requirements of each equipment. The reason why ergonomic requirements are divided into general ergonomic requirements and special ergonomic requirements is to refine the similarities and differences of the ergonomic requirements of each equipment, thereby reducing the setting of automatic inspection tools in subsequent steps.

[0042] In a specific embodiment of the present invention, the general ergonomic requirements include maintenance space requirements, installation height requirements, passage requirements, and accessibility requirements.

[0043] Maintenance space requirements refer to the space required by maintenance personnel when performing equipment maintenance, inspection or replacing parts when they are designed and arranged. These requirements ensure that maintenance personnel can access key parts of the equipment safely and efficiently while reducing maintenance time and costs.

[0044] Installation height requirements refer to the height of the equipment installation location, which is regulated by taking into account the operator's body size and operating convenience when designing and arranging the equipment. These requirements ensure that the equipment is easy to operate, maintain and inspect, while reducing the risk of injury to operators due to improper posture (such as excessive bending or reaching).

[0045] Access requirements focus primarily on ensuring that there is adequate space and passageways so that personnel can move safely and efficiently between equipment or between equipment and work areas. This includes ensuring that the width, height and layout of the passageways can accommodate the movement of personnel and equipment.

[0046] Accessibility requirements focus on ensuring that the location, height, and layout of equipment, control panels, instruments, and other operating elements can be operated and accessed by people of varying sizes and abilities.

[0047] For the above five types of equipment (local display instruments, remote transmission instruments, panel cabinets, manual valves, and non-manual valves), their ergonomic requirements include maintenance space requirements, installation height requirements, channel requirements, and accessibility requirements. Therefore, these ergonomic requirements are classified as general ergonomic requirements.

[0048] In a specific embodiment of the present invention, special ergonomic requirements include visibility requirements or equipment component accessibility requirements. Special ergonomic requirements are unique to certain types of equipment. For the above-mentioned on-site display instrument, since the instrument readings need to be read on-site, the ergonomic requirements for the on-site display instrument also include visibility requirements (i.e., instrument display orientation); for the above-mentioned manual valve, since the valve stem needs to be operated on-site, the ergonomic requirements for the manual valve also include equipment component accessibility requirements (i.e., valve stem accessibility requirements).

[0049] Step S400: Perform a human factors compliance check on each device according to the human factors engineering requirements of each device and the preset human factors compliance check tool library to obtain the inspection results. The human factors compliance check tool library refers to a collection of a series of tools and resources that are used to evaluate and verify whether the working environment, equipment, system or product design meets the requirements of human factors engineering. In this step, the preset human factors compliance check tool library not only stores these tools and resources, but also stores the human factors engineering requirements and their corresponding mapping relationships. In this way, when the human factors engineering requirements of each device are obtained according to step S300, an automatic inspection can be performed according to the preset human factors compliance check tool library to obtain the inspection results.

[0050] See also Figure 3 In a specific embodiment of the present invention, according to the human factors engineering requirements of each device and the preset human factors compliance inspection tool library, the human factors compliance inspection of each device is performed, including: S411, according to the maintenance space requirements of each device and the preset human factors compliance inspection tool library, the maintenance space virtual body of each device is obtained; S412, the maintenance space virtual body of each device is loaded into the location of the device in the three-dimensional model, and the maintenance space virtual body is checked for collision with the surrounding devices. If there is a collision, it means that the inspection of the maintenance space requirements of the device is not in compliance; if there is no collision, it means that the inspection of the maintenance space requirements of the device is in compliance.

[0051] The maintenance space virtual body is a concept used in computer-aided design and human factors engineering assessment. It is used to simulate the space required by maintenance personnel when performing equipment maintenance, inspection or replacing parts. This virtual body is usually created based on anthropometric data to ensure that the design meets the operational needs of most maintenance personnel. It is a virtual three-dimensional human model that represents the spatial range required by maintenance personnel when performing tasks. This model includes factors such as human size, limb motion range and operating posture.

[0052] The virtual body of the maintenance space is usually constructed through the following methods: (1) 3D modeling software: Use CAD software to create a virtual human model and simulate maintenance tasks; (2) Anthropometric data: Define the parameters of the virtual body based on anthropometric data, such as human size distribution, limb motion range, etc.; (3) Motion capture technology: Use motion capture technology to record the movements of actual maintenance personnel to obtain more accurate data; (4) Virtual reality: Simulate maintenance tasks in a virtual reality environment to evaluate and optimize the maintenance space. For each type of equipment, a corresponding virtual body of the maintenance space should be preset.

[0053] See also Figure 4 In a specific embodiment of the present invention, according to the human factors engineering requirements of each device and the preset human factors compliance inspection tool library, the human factors compliance inspection of each device is performed, including: S421, according to the channel requirements of each device and the preset human factors compliance inspection tool library, the human channel virtual body of each device is obtained; S422, the human channel virtual body of each device is loaded into the door of the room where the device is located in the three-dimensional model, and the path of the human channel virtual body from the door to the device is simulated, and whether there is a collision between the human channel virtual body and the surrounding equipment during the walking process. If there is a collision, it means that the channel requirement inspection of the device is not in compliance; if there is no collision, it means that the channel requirement inspection of the device is in compliance.

[0054] The human channel virtual body can be, for example, the "95th percentile male virtual body", which is a concept used in human factors engineering and industrial design, which creates a virtual human model based on anthropometric data. This model represents that in a specific population, 95% of the individuals have a body width (usually the width between the two shoulder peaks) that is less than or equal to the width of this virtual body. In other words, the width of this virtual body is a statistically defined value that ensures that at least 95% of the population can pass through or operate within the design space.

[0055] See also Figure 5 In a specific embodiment of the present invention, according to the human factors engineering requirements of each device and the preset human factors compliance inspection tool library, a human factors compliance inspection of each device is performed, including: S431, according to the accessibility requirements of each device and the preset human factors compliance inspection tool library, the virtual body of the personnel reachable domain of each device is obtained; S432, the virtual body of the personnel reachable domain of each device is loaded into the personnel reserved space of the location of the device in the three-dimensional model, and the device is checked whether it is in the reachable domain. If the device is in the reachable domain, it means that the check of the accessibility requirements of the device is in compliance; if the device is not in the reachable domain, it means that the check of the accessibility requirements of the device is not in compliance.

[0056] The virtual body of the reachable area of ​​personnel is a concept used in human factors engineering and industrial design to evaluate and design workspaces to ensure that operators can reach and operate equipment or control panels comfortably and safely. This virtual body is based on anthropometric data and simulates the spatial range that personnel can reach in a specific posture. It is a virtual three-dimensional human model that represents the spatial range that personnel arms, hands and tools can reach in a specific posture (such as standing, sitting, squatting, etc.). This model includes factors such as human size, limb motion range and operating posture.

[0057] See also Figure 6 In a specific embodiment of the present invention, according to the human factors engineering requirements of each device and the preset human factors compliance inspection tool library, the human factors compliance inspection of each device is performed, including: S441, according to the visibility requirements of each device and the preset human factors compliance inspection tool library, the personnel visual field virtual body of each device is obtained; S442, the personnel visual field virtual body of each device is loaded into the personnel reserved space of the location of the device in the three-dimensional model, and the device that needs to be read is checked whether it is in the visual field. If the device is in the visual field, it means that the inspection of the visibility requirements of the device is in compliance; if the device is not in the visual field, it means that the inspection of the visibility requirements of the device is not in compliance.

[0058] The virtual body of the human visual field is a concept used in human factors engineering and industrial design to evaluate and design the work environment to ensure that operators can clearly see the equipment, instruments or control panels they need to monitor or operate. This virtual body simulates the spatial range that a person can see in a specific posture based on human visual characteristics and anthropometry data. It is also a virtual three-dimensional human model that represents the spatial range that a person's eyes can observe in a specific posture (such as standing, sitting, etc.). This model includes factors such as a person's field of view, perspective and line of sight.

[0059] By constructing the above virtual bodies, automatic inspection of different ergonomic requirements can be achieved. For some other requirements, such as installation height requirements, there is no need to construct a virtual body. Instead, the height data of the equipment can be directly compared with some height data related to the human body to obtain the automatic inspection results of the installation height requirements. The above only lists some common automatic inspection processes for ergonomic requirements. For some other ergonomic requirements, the inspection process can be preset according to the actual situation.

[0060] After obtaining the inspection results, the inspection results can be displayed and exported, and iterative inspection can be performed after the non-conformities are rectified. By classifying the equipment in the 3D model and calling different inspection tools based on the equipment classification for automatic inspection, the inspection results and the non-conformity list can be automatically exported with one click after the inspection is completed. Improvement plans can be formulated for the non-conformity list, or it can be clarified that no modification is required. For the improved plan, iterative inspection can be performed again only for the improved part to obtain new inspection results.

[0061] It should be noted that the steps of the above methods are divided only for the purpose of clear description. When implementing, they can be combined into one step or some steps can be split and decomposed into multiple steps. As long as they contain the same logical relationship, they are all within the protection scope of this patent; adding insignificant modifications or introducing insignificant designs to the algorithm or process, but not changing the core design of the algorithm and process are all within the protection scope of this patent. Figure 7 The diagram shows a complete inspection flow chart in a real scenario.
