Description

Technical Field

[0001] The embodiments of the present application belong to the technical field of nuclear power emergency, and particularly relate to a method, device, electronic device, and computer program product for judging the leakage of a pressure boundary of a habitability space. Background Art

[0002] When a radioactive release accident occurs in a reactor or nuclear facility of a nuclear power plant, the reactor or faulty nuclear facility will generate radioactive air pollutants, and the generated radioactive air pollutants will diffuse into the surrounding environment. Therefore, during the construction of a nuclear power plant, a habitability area needs to be set within the area where the nuclear power plant is located, which is used for accident command, coordination, handling, and resettlement of personnel in case of a radioactive release accident. In order to prevent the habitability area from being affected by radioactive air pollutants, a pressure boundary needs to be set for the habitability area. The pressure boundary can serve as a barrier to prevent external radioactive air pollutants from entering the habitability area and maintain the cleanliness of the air inside the habitability area. At the same time, the emergency ventilation system in the habitability area provides fresh air filtered by radioactivity to pressurize the habitability area and jointly maintain the positive pressure margin and pressure stability inside the habitability area with the pressure boundary. The pressure boundary can be jointly composed of infrastructure such as physical barriers set around the habitability area, various ventilation systems passing through the physical barriers on the periphery of the habitability area, and various process pipelines passing through the physical barriers on the periphery of the habitability area.

[0003] However, due to the extremely strong diffusivity of gas molecules, even if a pressure boundary is set for the habitability area, air leakage or air ingress may still occur at the boundary of the habitability area, resulting in component exchange of the air inside and outside the habitability area, and a decrease in the air pressure inside the habitability area, thereby increasing the amount of radioactive air pollutants in the air inside the habitability area. In view of this, the staff of the nuclear power plant need to accurately identify the pressure boundary of the habitability area, confirm the leakage nature and danger degree of the pressure boundary, so as to monitor and control the leakage degree of the pressure boundary. Thus, it can be seen that pressure boundary management is an important means for a nuclear power plant to establish and maintain the actual habitability ability of a habitability area.

[0004] Due to historical reasons, domestic second-generation nuclear power plants lack a systematic identification method for pressure boundaries, resulting in difficulties for the staff to carry out precise and effective design, construction, and operation and maintenance management of pressure boundaries. If the same degree of reinforcement or sealing design and management is carried out for the entire habitability area, it may greatly increase the construction and operation and maintenance costs.

[0072] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. However, those skilled in the art should clearly understand that the present application can also be implemented in other embodiments without these specific details. In other cases, the detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present application.

[0073] When a radioactive release accident occurs in the reactor or nuclear facility of a nuclear power plant, the reactor or the faulty nuclear facility will generate radioactive air pollutants, and the generated radioactive air pollutants will diffuse into the surrounding environment. Therefore, an inhabitable area is set up in the nuclear power plant to be used as an emergency place in case of a radioactive release accident, such as places like the main control room and the emergency center. The inhabitable area can be physically isolated from the radioactive air pollutants through geotechnical construction to reduce the direct radiation exposure dose in the inhabitable area. In addition, an emergency ventilation system can also be installed in the inhabitable area. The emergency ventilation system can be used to filter the radioactive air pollutants outside the inhabitable area and provide air without radioactive air pollutants for the personnel in the inhabitable area; in addition, the emergency ventilation system can also pressurize the inhabitable area to prevent radioactive air pollutants from entering the inhabitable area.

[0074] Exemplarily, an emergency ventilation system of a nuclear power plant includes an air storage tank, in which uncontaminated compressed air is stored. After a radioactive release accident occurs in the nuclear power plant, the nuclear power plant can supply compressed air without radioactive air pollutants to the inhabitable area in the nuclear power plant through the air storage tank in the emergency ventilation system to maintain the breathing use of the personnel in the inhabitable area. After the compressed air in the air storage tank is exhausted, the nuclear power plant can restart the emergency ventilation system to continue to maintain the habitability of the inhabitable area. Among them, the inhabitable area of the nuclear power plant can be composed of various systems such as buildings, ventilation systems, air conditioning systems, radiation monitoring systems, etc. The inhabitable area can ensure the survival of the personnel in the inhabitable area and ensure that the radioactive exposure dose received by the personnel in the inhabitable area is lower than the preset dose threshold.

[0075] In order to prevent the inhabitable area from being affected by radioactive air pollutants, the inhabitable area should have a clear pressure boundary to prevent external radioactive air pollutants from entering the inhabitable area and serve as a clear demarcation between the inside and outside of the inhabitable area. When a radiation accident occurs outside the inhabitable area, the radioactive exposure dose received by the personnel in the inhabitable area should be controlled and meet the design requirements. Among them, the pressure boundary corresponding to the inhabitable area can be composed of the walls, floors, roofs, doors, penetrations, air ducts, valves of the inhabitable area, and the sum of the specific systems, subsystems and equipment that actually constitute the shielding boundary of the inhabitable area. When a radiation accident occurs outside the inhabitable area, the outside of the inhabitable area will be filled with radioactive air pollutants. Due to the strong diffusion ability of radioactive air pollutants, internal leakage events and / or external leakage events may occur in the pressure boundary of the inhabitable area.

[0076] Specifically, when radioactive air pollutants outside the inhabitable area diffuse into the inhabitable area through the pressure boundary in various unfiltered internal leakage ways, that is, an internal leakage event occurs in the pressure boundary of the inhabitable area. Among them, the pressure boundary where the internal leakage event occurs can be called the internal leakage boundary or the negative pressure boundary. When an internal leakage event occurs in the pressure boundary, radioactive air pollutants will enter the inhabitable area in the event of an accident, resulting in an increase in the concentration of radioactive air pollutants in the inhabitable area and an increase in the exposure dose of the personnel in the inhabitable area. When the air in the inhabitable area diffuses outside the inhabitable area through the pressure boundary, that is, an external leakage event occurs in the pressure boundary of the inhabitable area. The pressure boundary where the external leakage event occurs can be called the external leakage boundary or the positive pressure boundary. When an external leakage event occurs in the pressure boundary, the amount of air in the inhabitable area will decrease, resulting in a decrease in the air pressure in the inhabitable area and ultimately reducing the ability of the inhabitable area to resist radioactive air pollutants outside the area.

[0077] In the actual operation process, there is no pressure boundary that will never experience external leakage or internal leakage events. The air inside and outside the pressure boundary will leak externally or internally through a certain boundary object in the pressure boundary, resulting in the exchange of air components or the loss of air quality. Therefore, accurately identifying the boundary objects that constitute the pressure boundary in the habitable area and determining the leakage level corresponding to each boundary object is of practical significance and is the basis for all relevant technical and administrative control work. However, currently, the industry has insufficient understanding of the definition of the pressure boundary and lacks specific methods for identifying and dividing the pressure boundary. Relevant research, tests, and actual operation conditions show that: without a full and comprehensive understanding and reasonable design of the habitable area pressure boundary in the design stage, problems such as incomplete pressure boundaries, numerous boundary systems and equipment will occur, leading to situations such as many pressure boundaries and a high leakage probability of the pressure boundary, bringing insurmountable difficulties to operation and maintenance; during the operation of the habitability system, if there is no identification and lack of operation and maintenance in terms of the pressure boundary, the leakage probability of the pressure boundary will also increase, the habitability system cannot achieve the designed function, and the actual safety function will decline.

[0078] Since the habitable area in a nuclear power plant can be composed of multiple habitable spaces, the staff in the nuclear power plant need to conduct full-process control over the pressure boundaries of each habitable space in the habitable area: 1. The design department needs to reasonably and effectively design the habitable space from the perspective of the principle of the habitable space; 2. The construction department needs to improve the construction quality of the pressure boundary and verify the effectiveness and tightness of the constructed pressure boundary; 3. The operation and maintenance department needs to conduct effective operation and maintenance management of the habitable space.

[0079] Due to historical reasons, domestic second-generation nuclear power plants have not carried out the above-mentioned operations of effective design, construction verification, and operation and maintenance management for the habitable space. In view of this, the embodiments of this application propose a method for identifying boundary objects of the pressure boundary and a method for judging the leakage level of boundary objects, so as to accurately identify each boundary object that constitutes the pressure boundary in the habitable area and automatically determine the leakage level corresponding to each boundary object. Therefore, in the design stage of the habitable area, through the method provided in this embodiment, designers can accurately know the integrity of the pressure boundary of the designed habitable area and the leakage risk of the pressure boundary, so as to further adjust and optimize the design scheme of the habitable area. In the system installation stage, the construction process and sealing acceptance standards can be determined according to the leakage levels of each boundary object. In the operation stage of the habitable area, through the method provided in this embodiment, operation and maintenance personnel can determine and adjust the inspection frequency corresponding to each boundary object according to the leakage levels of each boundary object, and conduct targeted inspections on each boundary object according to the leakage levels, so as to reduce the inspection cost while reducing the leakage probability of the boundary object.

[0080] The technical solutions of this application will be described below through specific embodiments.

[0081] Refer to Figure 1 , which shows a schematic diagram of a method for judging leakage of a pressure boundary of a habitable space provided by an embodiment of the present application. This method can be applied to electronic devices such as computers, tablets, mobile terminals, large servers, etc. The above method may specifically include the following steps:

[0082] S101. Based on the space identifiers corresponding to each identifiable space in the area to be identified, determine at least one habitable space in the area to be identified.

[0083] In this embodiment, when a technician needs to obtain the pressure boundary corresponding to a certain area to be identified in a nuclear power plant and the leakage levels corresponding to each boundary object constituting the pressure boundary, the technician can input the building information corresponding to the area to be identified into the electronic device and issue a judgment instruction to the electronic device. Among them, the area to be identified can be a certain building in the nuclear power plant, or a certain floor in a certain building, or a certain area in a certain building. Exemplarily, the building information input by the technician can be the building drawing corresponding to the area to be identified, and the building drawing can include the space identifiers corresponding to each space in the area to be identified, the structural information of the ventilation system in the area to be identified, the structural information of the pipelines in the area to be identified, the positions, types, sizes, etc. of each building in the area to be identified, such as the positions, types, sizes of the walls.

[0084] After the electronic device obtains the building information input by the user, it can, in response to the judgment instruction, obtain the space identifiers corresponding to each identifiable space in the area to be identified from the building information, and determine at least one habitable space from the area to be identified according to the space identifiers corresponding to each identifiable space. Exemplarily, when the area to be identified is a certain building inside a nuclear power plant, the user can input the building information corresponding to the building into the electronic device. Among them, the building information can include the space identifiers corresponding to each room in the building. The electronic device can determine at least one habitable space from the building according to the space identifiers corresponding to each room. Specifically, for rooms such as control rooms, communication rooms, computer rooms, restrooms, kitchens, dining rooms, etc. in the building where the staff need to take shelter in the event of a radioactive leakage accident, the electronic device can determine the above rooms as habitable spaces.

[0085] S102. According to the object types of each target object in the area to be identified and the relative position relationship between the target object and the habitable space, determine the boundary objects corresponding to the habitable space from all the target objects.

[0086] In this embodiment, after the electronic device determines the inhabitable space in the area to be recognized, for each target object in the area to be recognized, the electronic device can determine the boundary object corresponding to the inhabitable space from all the target objects according to the object type corresponding to the target object and the relative position relationship between the target object and the inhabitable space. Among them, the target object in the area to be recognized can be an object that may exchange gas with the non-inhabitable space in the inhabitable space. Specifically, there can be at least three types of target objects in the area to be recognized. Specifically, the target objects in the area to be recognized can include target objects of the soil engineering type, target objects of the pipeline type, and target objects of the ventilation system type. Among them, the target objects of the soil engineering type can include, but are not limited to, various building components such as walls, floors, ceilings, doors, floor drains, various holes, expansion joints, etc. The target objects of the pipeline type can include, but are not limited to, sewage pipes, chilled water pipes, drinking water pipes, fire water pipes, compressed air pipes, etc. The target objects of the ventilation system type can include, but are not limited to, pipes, flanges, valves, sampling pipes, sampling ports, and instrument pipes in the ventilation system.

[0087] After the electronic device determines the object type corresponding to each target object, it can determine whether the target object is a boundary object according to the relative position relationship between the target object and the inhabitable space and the boundary object determination condition corresponding to the object type of the target object. Specifically, for a target object whose relative position relationship satisfies the boundary object determination condition corresponding to the object type, the electronic device can determine the target object as a boundary object. For a target object whose relative position relationship does not satisfy the boundary object determination condition corresponding to the object type, the electronic device can determine that the target object is not a boundary object.

[0088] S103. Obtain the index data corresponding to the leakage determination condition through the leakage determination condition corresponding to the boundary object, and determine the leakage level corresponding to the boundary object according to the index data and the leakage determination condition.

[0089] In this embodiment, for any inhabitable space in the area to be recognized, after the electronic device determines the boundary object corresponding to the inhabitable space, it can obtain the index data related to the leakage determination condition of the boundary object through the leakage determination condition corresponding to the boundary object. The electronic device can determine the leakage level corresponding to the boundary object according to the index data and the leakage determination condition. Specifically, the electronic device can determine the leakage determination condition corresponding to the boundary object according to the object type corresponding to the boundary object, and obtain the index data related to the leakage determination condition of the boundary object.

[0090] S104. Generate a leakage prompt message based on the leakage levels corresponding to each boundary object.

[0091] In this embodiment, after the electronic device determines the leakage levels corresponding to each boundary object, it can generate leakage prompt information corresponding to the boundary object according to the leakage levels corresponding to each boundary object, and send the leakage prompt information to the target device to inform the user of the leakage level and treatment method corresponding to the boundary object.

[0092] Through the method provided in this embodiment, since the electronic device can automatically identify each boundary object constituting the pressure boundary of the inhabitable space, and automatically determine the leakage level corresponding to the boundary object according to the leakage judgment conditions and index data corresponding to each boundary object. Compared with the prior art, the method provided in this embodiment enables the electronic device to accurately identify each boundary object corresponding to the inhabitable space, so that the staff of the nuclear power plant can perform accurate design, management and maintenance based on the boundary objects identified by the electronic device. In addition, since the electronic device can automatically determine the leakage level corresponding to the boundary object after identifying the boundary object, the staff of the nuclear power plant can perform targeted and accurate management on the boundary object according to the leakage level, improve the accuracy of boundary object management, and reduce the speed of diffusion of radioactive air pollutants into the inhabitable space.

[0093] In a possible implementation manner, after the electronic device determines the leakage level corresponding to the boundary object, it can determine the leakage prompt information corresponding to the boundary object according to the type of the area to be recognized. Exemplarily, after the electronic device determines the leakage level corresponding to the boundary object, it can judge whether the current area to be recognized is a built area or an area to be built according to the construction status in the building information corresponding to the area to be recognized.

[0094] When the construction status corresponding to the area to be recognized is the built status, that is, when the area to be recognized is a built area, the electronic device can query the frequency mapping relationship preset by the R & D personnel according to the leakage levels corresponding to each boundary object to determine the maintenance frequency information corresponding to the leakage level of each boundary object, and generate leakage prompt information including the maintenance frequency information. Specifically, the frequency mapping relationship may include multiple leakage levels and the maintenance frequency information corresponding to each leakage level respectively. Exemplarily, the leakage levels may include three levels: high risk level, medium risk level and low risk level. The maintenance frequency information corresponding to the high risk level in the frequency mapping relationship may be once every two days; the maintenance frequency information corresponding to the medium risk level may be once a week; the maintenance frequency information corresponding to the low risk level may be once every two weeks.

[0095] In the case where the construction state corresponding to the area to be identified is a state to be constructed, that is, in the case where the area to be identified is an area to be constructed, the electronic device can determine whether the boundary object meets the preset adjustment conditions according to the leakage level corresponding to the boundary object. Specifically, the leakage level corresponding to the boundary object can include three levels: high risk level, medium risk level and low risk level. When the leakage level corresponding to a certain boundary object is a high risk level, the electronic device can determine that the boundary object meets the adjustment conditions. When the leakage level corresponding to a certain boundary object is a medium risk level or a low risk level, the electronic device can determine that the boundary object does not meet the adjustment conditions. For any boundary object that meets the adjustment conditions, the electronic device can generate the position adjustment information corresponding to the boundary object according to the relative position relationship between the boundary object and the habitable space, and generate leakage prompt information according to the position adjustment information of the boundary object and the leakage level. Among them, the position adjustment information generated by the electronic device may include the target position corresponding to the boundary object, and the corresponding leakage level when the boundary object is adjusted to the target position. For any boundary object that does not meet the adjustment conditions, the electronic device can generate leakage prompt information according to the leakage level corresponding to the boundary object.

[0096] Through the method provided in this embodiment, since the electronic device can generate different leakage prompt information for the built area or the area to be built according to the area to be identified, the method provided in this embodiment can improve the effectiveness of the leakage prompt information generated by the electronic device. In addition, the method provided in this embodiment can significantly reduce the identification and classification of pressure boundaries through the habitable area, so the method provided in this embodiment can provide clear guidance and help for the design, construction and operation and maintenance of the habitable space from the perspective of radiation control.

[0097] In order to accurately identify the habitable space in the area to be identified, an embodiment of the present application provides a method for identifying the habitable space. Figure 2 FIG. 1 shows a specific implementation flow chart of a method S101 for determining leakage of a pressure boundary of a habitable space provided in the second embodiment of the present application. Figure 2 , compared to Figure 1 In the embodiment, the present embodiment provides a method for determining leakage of a pressure boundary of a habitable space, wherein S101 includes: S1011 to S1013, which are described in detail as follows:

[0098] S1011. For any space to be identified, if there is a space identifier corresponding to any space to be identified in the preset occupancy list, then any space to be identified is determined as an actual habitable space.

[0099] In this embodiment, the area to be identified may include at least one space to be identified. Figure 3 , showing a schematic diagram of a habitable space provided in an embodiment of the present application. Figure 3As shown in the figure, the inhabitable space in the area to be recognized may include the actual inhabitable space and the buffer space. Among them, the actual inhabitable space may be the space where ventilation is carried out by the emergency ventilation system under nuclear emergency conditions. Specifically, the actual inhabitable space may include the emergency space and the non-emergency space. The emergency space may be a room in the actual inhabitable space where emergency personnel need to stay or the entry frequency of emergency personnel is greater than or equal to the frequency threshold. The non-emergency space may be a room required for the ventilation system to perform the ventilation function in the actual inhabitable space and a room where the entry frequency of emergency personnel is less than the frequency threshold. The buffer space may be a space used to reduce the air exchange volume between the actual inhabitable space and the non-inhabitable space. The buffer space may include the buffer space of the room type and the buffer space of the passage type. In a possible implementation, when the area to be recognized is a certain floor of a certain building in a nuclear power plant, the electronic device may regard a certain room or a certain passage on this floor as a space to be recognized. For a certain space to be recognized in the area to be recognized, the electronic device may query whether there is a space identifier corresponding to this space to be recognized in the preset residence list. If there is a space identifier corresponding to a certain space to be recognized in the residence list, the electronic device may determine that this space to be recognized is the actual inhabitable space. Exemplarily, for the space to be recognized with the room number L543 in the area to be recognized, its corresponding room identifier may be the technical support room. The electronic device may query whether the technical support room exists in the residence list. If the technical support room exists in the residence list, the electronic device may determine the space to be recognized with the room number L543 as the actual inhabitable space.

[0100] Specifically, the residence list may include the space identifiers corresponding to the spaces where emergency personnel need to live and / or work in the case of a radioactive release accident, such as emergency spaces like the control room, communication room, computer room, meeting room, restroom, kitchen, dining room, and lounge. The residence list may also include the space identifiers corresponding to the spaces required for the ventilation system to perform the ventilation function in the case of a radioactive release accident, such as the return air room and the supply fan room. The residence list may also include non-emergency spaces such as the control cabinet room and the protection cabinet room for servicing the nuclear power unit where the entry frequency of the staff is less than the frequency threshold in case of an emergency. It should be noted that when technicians divide the actual inhabitable space, they should not use whether personnel need to enter or stay as the judgment criterion in the case of a radioactive release accident, but should use whether it meets the ventilation operation of the emergency ventilation system as the judgment criterion. Exemplarily, in the case of a radioactive release accident, for the control cabinet room, even if emergency personnel rarely enter or stay in the control cabinet room, but because the control cabinet room is also ventilated by the emergency ventilation system, it also needs to be recognized as the actual inhabitable space.

[0101] In a possible implementation, for any to-be-identified space in the to-be-identified area, the electronic device can determine whether the to-be-identified space is a space where ventilation operations are performed through the emergency ventilation system in a nuclear emergency state according to the floor plan of the building and the flow chart of the emergency ventilation system. For any to-be-identified space, if the electronic device determines that the to-be-identified space is a space where ventilation operations are performed through the emergency ventilation system in a nuclear emergency state, the electronic device can determine that the to-be-identified space is an actually habitable space. If the electronic device determines that the to-be-identified space is not a space where ventilation operations are performed through the emergency ventilation system in a nuclear emergency state, the electronic device can determine that the to-be-identified space is not an actually habitable space. Among them, the emergency ventilation system refers to a ventilation system that can provide ventilation for the habitable area to control the diffusion of airborne radioactive substances into the habitable area when an accident occurs in a nuclear power plant.

[0102] S1012. If there is no space identifier corresponding to any to-be-identified space in the residence list, determine whether any to-be-identified space meets the buffer condition based on the connectivity relationship between any to-be-identified space and the actually habitable space.

[0103] In this embodiment, for a certain to-be-identified space in the to-be-identified area, if there is no space identifier corresponding to the to-be-identified space in the residence list, the electronic device can determine whether the to-be-identified space meets the buffer condition based on the connectivity relationship between the to-be-identified space and the actually habitable space. Specifically, for a to-be-identified space for which there is no corresponding space identifier in the residence list, if there is a passage door connecting the to-be-identified space and any actually habitable space, the electronic device can determine that the connectivity relationship between the to-be-identified space and the actually habitable space meets the buffer condition, and the electronic device can identify the to-be-identified space as a buffer space. For a to-be-identified space for which there is no corresponding space identifier in the residence list, if there is no passage door connecting the to-be-identified space and any actually habitable space, the electronic device can determine that the connectivity relationship between the to-be-identified space and the actually habitable space does not meet the buffer condition, and the electronic device can not identify the to-be-identified space as a buffer space.

[0104] In a possible implementation, after the electronic device identifies the buffer space, it can determine the type corresponding to the buffer space according to the connectivity relationship between the buffer space and the non-habitable space. Specifically, for any buffer space, if there is a passage door connecting the buffer space and the non-habitable space, the electronic device can identify the buffer space as a passage-type buffer space. For any buffer space, if there is no passage door connecting the buffer space and the non-habitable space, the electronic device can identify the buffer space as a room-type buffer space.

[0105] S1013. If the connectivity relationship between any space to be recognized and the actual habitable space meets the buffer condition, then determine any space to be recognized as a buffer space.

[0106] In this embodiment, for a space to be recognized for which there is no corresponding space identifier in the residence list, if the electronic device determines that the connectivity relationship between the area to be recognized and the actual habitable space meets the buffer condition, then the electronic device can determine the space to be recognized as a buffer space, that is, the space to be recognized is a habitable space. For a space to be recognized for which there is no corresponding space identifier in the residence list, if the electronic device determines that the connectivity relationship between the area to be recognized and the actual habitable space does not meet the buffer condition, then the electronic device can determine the space to be recognized as a non-habitable space.

[0107] In this embodiment, since the electronic device can first identify the actual habitable space in the area to be recognized, and then determine a space to be recognized whose connectivity relationship with the actual habitable space meets the buffer condition as a buffer space, therefore, the method provided in this embodiment can improve the accuracy of the habitable space recognized by the electronic device.

[0108] In order to further accurately identify each boundary object corresponding to the habitable space, the embodiment of the present application provides a specific method for determining whether a target object is a boundary object according to the object type of the target object and the relative position relationship between the target object and the habitable space. Figure 4 FIG. shows a specific implementation flowchart of a method S102 for judging leakage of a pressure boundary of a habitable space provided in the second embodiment of the present application. Refer to Figure 4 , compared with Figure 4 the embodiment described above, in a method S102 for judging leakage of a pressure boundary of a habitable space provided in this embodiment, S102 includes: S1021 to S1023, which are specifically described in detail as follows:

[0109] S1021. If the object type of the target object is a geotechnical type and the target object is located at the connection between the habitable space and the non-habitable space, then recognize the target object as a boundary object.

[0110] In this embodiment, after the electronic device determines any inhabitable space in the area to be recognized, for a certain inhabitable space in the area to be recognized, the electronic device may first obtain the target objects of the soil engineering type in this inhabitable space. For the target objects of the soil engineering type, if the target object is located at the connection between the inhabitable space and the non-inhabitable space, the electronic device may recognize the target object as a boundary object. For the target objects of the soil engineering type, if the target object is not located at the connection between the inhabitable space and the non-inhabitable space, the electronic device determines that the target object is not a boundary object. Among them, the target objects of the soil engineering type in a certain inhabitable space may include the indoor interfaces in this inhabitable space, building components installed on any indoor interface, holes on any indoor interface, etc.

[0111] Exemplarily, the indoor interfaces in the inhabitable space may include interfaces such as walls, floors, and ceilings in the inhabitable space. The building components installed on any indoor interface may be building components such as doors, windows, and expansion joints on a certain wall. Among them, the expansion joint may be located on any indoor interface and is a structural joint pre-set to reduce cracks in the indoor interface due to reasons such as climate and temperature changes (thermal expansion and contraction), and is usually filled with flexible materials such as waterstops and sealing strips. A door on a certain wall may be composed of components such as door leaves, hinges, sealing strips, and lock tongues. The holes on any indoor interface are various holes that penetrate the interface on the indoor interface, and the holes can be used to provide channels for various mechanical pipelines, electrical and instrument equipment, and cables that pass through the inhabitable space, such as cable holes on a certain wall in the inhabitable space, wire holes of a certain electrical and instrument equipment, etc. Specifically, the holes on the wall may include the hole opening and the sealing material on the hole opening. The floor drain may be a floor drainage outlet and / or sewage outlet provided on the ground of the inhabitable space, and may be composed of components such as a floor drain cover plate, a floor drain groove, and floor drain liquid.

[0112] In a possible implementation manner, the boundary objects of the soil engineering type may include boundary surfaces, boundary components, boundary holes, and floor drains. For all the floor drains inside the inhabitable space, since all the floor drains are connected to the drainage pipes and / or sewage pipes that communicate with the outside of the building, the electronic device may recognize all the floor drains inside the inhabitable space as boundary objects. Refer to Table 1 below, which shows a schematic table of floor drain statistics provided in the embodiments of the present application.

[0113]

[0114]

[0115] Table 1 Schematic Table of Floor Drain Statistics

[0116] For other target objects of the geotechnical type other than floor drains, since target objects such as holes and building components are all installed on the indoor interface, the electronic device can first perform boundary object recognition on the indoor interface to determine the boundary surface that serves as a boundary object in the indoor interface, and then determine other boundary objects of the geotechnical type based on the boundary surface. For any indoor interface of the geotechnical type, if the indoor interface is at the connection between the inhabitable space and the non-inhabitable space, the electronic device can determine that the indoor interface is the boundary surface between the inhabitable space and the non-inhabitable space, that is, the electronic device can determine the indoor interface as a boundary object.

[0117] Furthermore, after the electronic device determines that it is the boundary surface between the inhabitable space and the non-inhabitable space, it can determine all the holes and building components installed on this boundary surface as the boundary objects corresponding to the inhabitable space. Exemplarily, after determining a certain boundary surface, the electronic device can determine the doors, windows, and expansion joints installed on this boundary surface as boundary components on this boundary surface, and determine the holes on this boundary surface as boundary holes. After the electronic device determines all the boundary objects of the geotechnical type in the inhabitable space, it can determine the boundary formed by all the boundary objects of the geotechnical type as the pressure boundary of the geotechnical type corresponding to the inhabitable space, that is, determine the boundary formed by all the boundary objects of the geotechnical type as the geotechnical boundary.

[0118] See Figure 5 , which shows a building plan schematic diagram of a region to be recognized provided by an embodiment of the present application. Figure 5 All the rooms inside the black frame in are the inhabitable spaces corresponding to the region to be recognized. Among them, Figure 5 All the floor drains in the inhabitable space in are boundary objects. All the indoor interfaces at the connection between the inhabitable space and the non-inhabitable space are boundary surfaces. All the holes on any boundary surface are boundary holes. All the building components on any boundary surface are boundary components. Specifically, Figure 5 The rooms with room numbers L502, L505, L507, L511, L543, L545, L547, and W505 in can all be inhabitable spaces. When a radioactive release accident occurs, the emergency ventilation system in the inhabitable space can provide uncontaminated air for the above rooms.

[0119] Exemplarily, for Room L545, its left wall, right wall, and rear wall are all connected to non - habitable spaces. That is, the left wall, right wall, and rear wall of Room L545 are all located at the connection between the habitable space and the non - habitable space. Therefore, the above - mentioned three walls are all the boundary surfaces corresponding to Room L545. The front wall of Room L545 is connected to Room L547 which belongs to the habitable space. That is, the front wall of Room L545 is located at the connection between habitable spaces. Therefore, this wall does not belong to the boundary surface. Regarding whether the floor of Room L545 is a boundary surface, the electronic device needs to judge according to the nature of the space under the floor of Room L545. Specifically, if the space under the floor of Room L545 is a non - habitable space, the electronic device can determine that the floor of Room L545 is a boundary surface; if the space under the floor of Room L545 is a habitable space, the electronic device can determine that the floor of Room L545 is not a boundary surface. Regarding whether the ceiling of Room L545 is a boundary surface, the electronic device needs to judge according to the nature of the space above the ceiling of Room L545. Specifically, if the space above the ceiling of Room L545 is a non - habitable space, the electronic device can determine that the ceiling of Room L545 is a boundary surface; if the space above the ceiling of Room L545 is a habitable space, the electronic device can determine that the ceiling of Room L545 is not a boundary surface. For Room L543, after identification, all the interior interfaces in this room are in contact with non - habitable spaces. Therefore, all the interior interfaces in Room L543 are boundary surfaces.

[0120] See Table 2 below, which is a Figure 5 schematic table of the interior interfaces of the main rooms in a habitable space provided by an embodiment of the present application.

[0121]

[0122]

[0123] Table 2 Schematic table of the interior interfaces of the main rooms in a habitable area S1022. If the object type of the target object is a ventilation system type and there is a connection relationship between the target object and any habitable space, then the target object is identified as the boundary object corresponding to the habitable space.

[0124] In this embodiment, for a target object of the ventilation system type, if there is a connection relationship between the target object and any inhabitable space, the electronic device can identify the target object as a boundary object corresponding to the inhabitable space. If there is no connection relationship between the target object of the ventilation system type and any inhabitable space, the electronic device can determine that the target object is not a boundary object. If a target object of a certain ventilation system type is installed on the boundary surface of an inhabitable space, or a target object of a certain ventilation system type is installed on a pipeline having a connection relationship with the boundary surface of the inhabitable space, the electronic device can determine that the target object is a boundary object of the ventilation system type. Specifically, the boundary objects of a certain ventilation system type may include, but are not limited to, all ventilation system pipelines, flanges, valves, sampling pipes / ports, instrument pipes, mufflers, electrical instrument cable perforations, maintenance holes, and measurement holes, etc., of the ventilation system passing through the inhabitable space. Among them, the pipelines of the ventilation system may include, but are not limited to, pipelines of types such as fresh air pipeline type and air circulation pipeline type in the ventilation system.

[0125] It should be noted that the boundary objects of the ventilation system type corresponding to a certain inhabitable space are not judged by whether the ventilation system serves the inhabitable space. Therefore, when the electronic device judges the boundary objects of the target objects of the ventilation system type, it can be divided into two cases: judging the boundary objects of the ventilation system serving non-inhabitable spaces and judging the boundary objects of the emergency ventilation system serving inhabitable spaces.

[0126] 1. Judging the boundary objects of the ventilation system serving non-inhabitable spaces.

[0127] For a ventilation system serving a non - habitable space, that is, for such a ventilation system, the electronic device can determine that the ventilation system is a non - emergency ventilation system. For a non - emergency ventilation system, if some of the equipment of the non - emergency ventilation system crosses the boundary surface of the habitable space and there is a connection relationship between some parts of the non - emergency ventilation system and the habitable space, then the electronic device can determine all the equipment located in the habitable space in the non - emergency ventilation system, such as all the ventilation ducts and components located in the habitable space in the non - emergency ventilation system, as boundary objects corresponding to the habitable space. For example, in the main control room of the M310 reactor type unit, in addition to the emergency ventilation system serving the habitable area of the main control room, there are also fans and ducts of the ventilation system serving the cable layer and ducts of the ventilation system serving the electrical compartment. Among them, the habitable area of the main control room is the habitable space, while the cable layer and the electrical compartment are non - habitable spaces. For the ventilation system serving the cable layer and the ventilation system serving the electrical compartment, the ventilation equipment, such as ventilation ducts and fans, arranged in the habitable area of the main control room in the above - mentioned two non - emergency ventilation systems, are boundary objects of the ventilation system type of the habitable space and can be described as "D1DVE013ZV supply air circuit pipeline boundary" or "D1DVL intake air 405VA circuit pipeline boundary".

[0128] 2. Determine the boundary objects for the emergency ventilation system serving the habitable space.

[0129] For a ventilation system serving a habitable space, the electronic device can determine that the ventilation system is an emergency ventilation system. Since there are often multiple connection relationships between the emergency ventilation system serving the habitable space and the habitable space, the electronic device can identify the boundary objects corresponding to the habitable space according to the positional relationship between each device in the emergency ventilation system and the habitable space. For example, in the main control room of an AP1000 nuclear power unit, there is also a specially - arranged independent ventilation system that can provide compressed air, which is used to give priority to supplying fresh air and cold source to the main control room and maintaining the positive pressure state of the main control room in case of an accident. Among them, some of the equipment of this ventilation system may be arranged in the non - habitable space, but because this ventilation system serves the habitable area of the main control room and there are multiple connection relationships with the habitable area of the main control room, the electronic device can identify this part of the equipment in the ventilation system as a pressure boundary.

[0130] In a possible implementation, refer to Figure 6 , which shows a schematic diagram of an emergency ventilation system serving a habitable space provided by an embodiment of the present application. As Figure 6As shown, the emergency ventilation system may include a purification unit and a main ventilation unit. Among them, ventilation ducts may be respectively connected between the emergency space and the return air chamber, the supply air chamber, and the fresh air inlet chamber. Specifically, the ventilation duct pointing from the emergency space to the return air chamber may be a return air duct, the ventilation duct pointing from the supply air chamber to any space that needs to perform ventilation operations may be a supply air duct, and the ventilation duct pointing from the space that needs to perform ventilation operations to the fresh air inlet chamber may be a return air purification duct. Among them, the space that needs to perform ventilation operations may include the emergency space, as well as the rooms in the non-emergency space where the control cabinets are placed and the rooms where the protection cabinets are placed. A purification loop supply fan may be connected between the purification unit and the return air chamber, for transporting the air filtered by the purification unit to the return air chamber. A main ventilation loop supply fan may be connected between the return air chamber and the supply air chamber, for transporting the air in the return air chamber to the supply air chamber.

[0131] In the case of no radioactive release accident, the isolation valve of the fresh air inlet duct of the main ventilation unit may be in the open state, and the purification unit may be in the shutdown state. At this time, the outside air may enter the return air chamber through the fresh air inlet duct of the main ventilation unit, and then reach each space that needs to perform ventilation operations in the actually habitable space via the main ventilation loop supply fan, the supply air chamber, and the supply air duct. At the same time, the air in each space that needs to perform ventilation operations may converge into the return air chamber through the return air duct, and return to the emergency space via the supply fan of the main ventilation unit, the supply air chamber, and the supply air duct to achieve air circulation.

[0132] In the event of a radioactive release accident, the staff can close the isolation valve of the fresh air inlet pipeline of the main ventilation unit to stop obtaining outside air through the fresh air inlet pipeline of the main ventilation unit. At the same time, the purification unit can be in an operating state. At this time, outside air can enter the air inlet chamber through the purification unit via the fresh air inlet pipeline of the purification unit and reach the purification unit for filtration. Meanwhile, the isolation valve of the return air purification pipeline is opened, and part of the return air in the space where ventilation operation needs to be performed enters the air inlet chamber through this pipeline, realizing the filtration function of part of the return air. The purification circuit blower can transmit the filtered air to the return air chamber. The air in the return air chamber can reach each space where ventilation operation needs to be performed in the actual habitable space via the main ventilation circuit blower, the air supply chamber, and the air supply pipeline. At the same time, the air in each space where ventilation operation needs to be performed can achieve air circulation through two different paths. Specifically, part of the air in the space where ventilation operation needs to be performed can converge into the return air chamber through the return air pipeline and then reach the space where ventilation operation needs to be performed again through the blower of the main ventilation unit, the air supply chamber, and the air supply pipeline, realizing air circulation; another part of the air can reach the purification unit for filtration through the return air purification pipeline via the air inlet chamber, and then the filtered air can return to the space where ventilation operation needs to be performed through the purification circuit blower, the return air chamber, the main ventilation circuit blower, the air supply chamber, and the air supply pipeline to achieve air circulation.

[0133] Among them, the main ventilation unit (mainly composed of a return air chamber, a blower, an air supply chamber, etc.) of the emergency ventilation system serving the habitable space should be arranged within the habitable space. Because the air in the ventilation system serving the habitable space is completely connected to the air in the habitable space, if the main ventilation unit is arranged outside the habitable space, it will cause the boundary of the ventilation system of the habitable space to extend to the non-habitable space, resulting in a more complex boundary of the ventilation system of the habitable space, a higher leakage level of the ventilation system boundary, and more difficult operation and maintenance after a radioactive release accident.

[0134] In a possible implementation manner, according to the equipment type of the target object in the emergency ventilation system, the electronic device can specifically divide the boundary object judgment of the target object corresponding to the emergency ventilation system type into three cases. Among them, the equipment type of the target object in the ventilation system can include the fresh air pipeline type, the air circulation pipeline type, and the purification component type.

[0135] 2.1. Perform boundary object judgment on the target object of the fresh air pipeline type.

[0136] In a possible implementation manner, for the target object of the air circulation pipeline type, the electronic device can identify the pipeline part of the target object located within the habitable space as a boundary object.

[0137] In a possible implementation, for a target object of the fresh air duct type, the electronic device can determine the boundary object of the fresh air duct type from the target object according to the number of isolation valves included in the target object and the first positional relationship between each isolation valve and the inhabitable space. When the device type of the target object is the fresh air duct type and there is only one isolation valve in the target object, the electronic device can perform boundary object recognition according to the first positional relationship between the isolation valve and the inhabitable space. Specifically, according to the number of isolation valves in the fresh air duct, the electronic device's determination of the boundary object for the target object of the fresh air duct type can be specifically divided into two cases: determining the boundary object for the target object of the single-valve fresh air duct type and determining the boundary object for the target object of the double-valve fresh air duct type.

[0138] 2.1.1. Determine the boundary object for the target object of the single-valve fresh air duct type.

[0139] See Figure 7 , which shows a schematic diagram of the boundary object of a single-valve fresh air duct type provided by an embodiment of the present application. As Figure 7 shown, when there is only one isolation valve on the fresh air duct and the isolation valve in the boundary object is located outside the inhabitable space, the electronic device can identify the isolation valve and the pipe section starting from the pipe where the isolation valve is located until the soil boundary of the inhabitable space as the boundary object of the ventilation system type corresponding to the inhabitable space. As Figure 7 shown, the black line part is used to represent the pressure boundary corresponding to the inhabitable space. The gray line part is used to represent the pressure boundary corresponding to the inhabitable space. Among them, the pressure boundary corresponding to the inhabitable space can include the soil boundary formed by the boundary object of the soil type and the ventilation system boundary formed by the boundary object of the ventilation system type.

[0140] See Figure 8 , which shows another schematic diagram of the boundary object of the single-valve fresh air duct type provided by an embodiment of the present application. As Figure 8 shown, when there is only one isolation valve in the target object of the fresh air duct type and the isolation valve in the boundary object is located inside the inhabitable space, the electronic device can identify the isolation valve and the pipe section located inside the inhabitable space as the boundary object.

[0141] 2.1.2. Determine the boundary object for the target object of the double-valve fresh air duct type.

[0142] When the device type of the target object is the fresh air duct type and the target object contains multiple isolation valves, the electronic device can identify boundary objects according to the first positional relationship between each isolation valve and the inhabitable space. Among them, when the electronic device judges the boundary objects of the target object of the double-valve fresh air duct type, it can be divided into two cases according to whether the pressure pipeline is included in the target object.

[0143] 2.1.2.1. The target object of the double-valve fresh air duct type that does not contain a pressure pipeline.

[0144] See Figure 9 , which shows a schematic diagram of the boundary object of a double-valve fresh air duct type provided by an embodiment of the present application. As Figure 9 shown, since the target object of the double-valve fresh air duct type contains two isolation valves, the first isolation valve can be the first isolation valve that the gas needs to pass through on the way into the inhabitable space through the fresh air duct. The second isolation valve can be the second isolation valve that the gas needs to pass through on the way into the inhabitable space through the fresh air duct. Since Figure 9 in the shown target object, all isolation valves are located outside the inhabitable space, so the electronic device can identify the pipeline and isolation valves between the start of the first isolation valve and the connection to the geotechnical boundary as the boundary object of the ventilation system type corresponding to the inhabitable space.

[0145] See Figure 10 , which shows a schematic diagram of another boundary object of the double-valve fresh air duct type provided by an embodiment of the present application. As Figure 10 shown, at this time, the first isolation valve in the target object is located inside the inhabitable space, and the second isolation valve is located outside the inhabitable space. At this time, since the two isolation valves in the boundary object are respectively located on both sides of the geotechnical boundary of the inhabitable space, the electronic device can identify the pipeline between the second isolation valve and the geotechnical boundary as the boundary object of the ventilation system type.

[0146] See Figure 11 , which shows a schematic diagram of another boundary object of the double-valve fresh air duct type provided by an embodiment of the present application. As Figure 11 shown, at this time, the isolation valves in the target object are all located inside the inhabitable space. In the case where the isolation valves are all located inside the inhabitable space, the electronic device can identify the two isolation valves and the part of the pipeline where the two isolation valves are located that is inside the inhabitable space as the boundary object of the ventilation system type corresponding to the inhabitable space.

[0147] 2.1.2.2. The target object of the double-valve fresh air duct type that contains a pressure pipeline.

[0148] 2.1.2.2.1. The pressure pipeline is located outside the inhabitable space.

[0149] SeeFigure 12 , showing a schematic diagram of another boundary object of the double - channel valve fresh - air duct type provided by the embodiments of the present application. As Figure 12 shown, all isolation valves and pressurized pipelines in the target object of the double - channel valve fresh - air duct type are located outside the geotechnical boundary of the habitable space. In this case, the electronic device can identify the second isolation valve and the pipeline section from the location of the second isolation valve to the geotechnical boundary of the habitable space as the boundary object of the ventilation system type corresponding to the habitable space. The electronic device can also determine whether the pressurized pipeline belongs to a part of the boundary object according to the gas source in the pressurized pipeline. Specifically, if the gas source in the pressurized pipeline is filtered compressed air, the pressurized pipeline does not belong to a part of the boundary object. If the gas source in the pressurized pipeline is the air in the air supply chamber, the pressurized pipeline is a part of the boundary object. In summary, in the case where the gas source in the pressurized pipeline is filtered compressed air, the electronic device can Figure 12 in the target object shown, identify the second isolation valve and the pipeline section from the location of the second isolation valve to the geotechnical boundary of the habitable space as the boundary object. In the case where the gas source in the pressurized pipeline is the air in the return air chamber, the electronic device can Figure 12 in the target object shown, identify the pressurized pipeline, the second isolation valve, and the pipeline section from the location of the second isolation valve to the geotechnical boundary of the habitable space as the boundary object.

[0150] Refer to Figure 13 , showing a schematic diagram of another boundary object of the double - channel valve fresh - air duct type provided by the embodiments of the present application. As Figure 13 shown, in the target object of the double - channel valve fresh - air duct type, the second isolation valve is located inside the habitable space, while the first isolation valve and the pressurized pipeline are located outside the habitable space. In this case, the electronic device can perform boundary object identification on the target object according to the gas source in the pressurized pipeline. Specifically, if the gas source in the pressurized pipeline is filtered compressed air, the electronic device can identify the second isolation valve in the target object and the pipeline section between the second isolation valve and the geotechnical boundary as the boundary object. If the gas source in the pressurized pipeline is the air in the air supply chamber, the electronic device can identify the pressurized pipeline, the second isolation valve, and the pipeline section between the pressurized pipeline and the first and second isolation valves as the boundary object.

[0151] 2.1.2.2.2. The pressurized pipeline is located inside the habitable space.

[0152] Refer to Figure 14 , showing a schematic diagram of another boundary object of the double - channel valve fresh - air duct type provided by the embodiments of the present application. As Figure 14As shown, in the target object of the double - channel valve fresh - air duct type, part of the second isolation valve and the pressure - charging pipeline is located within the habitable space, while the first isolation valve is located outside the habitable space. In this case, the electronic device can identify the pipeline part of the pressure - charging pipeline located within the habitable space, the second isolation valve, and the pipeline part between the first isolation valve and the geotechnical boundary as boundary objects.

[0153] See Figure 15 , which shows a schematic diagram of another boundary object of the double - channel valve fresh - air duct type provided by the embodiment of the present application. As Figure 15 shown, in the target object of the double - channel valve fresh - air duct type, the second isolation valve, the first isolation valve, and the pressure - charging pipeline are located within the habitable space. In this case, the electronic device can identify the devices of the target object located within the habitable space as boundary objects. Specifically, the electronic device can identify the part of the pressure - charging pipeline located within the habitable space, the second isolation valve, the first isolation valve, and the pipeline part between the second isolation valve and the geotechnical boundary as boundary objects.

[0154] Through the method provided by this embodiment, for the target object of the fresh - air duct type, since the electronic device can determine the boundary objects of the fresh - air duct type from the target object according to the number of isolation valves included in the target object and the first positional relationship between each isolation valve and the habitable space, the method provided by this embodiment can improve the recognition accuracy of the boundary objects of the fresh - air duct type.

[0155] 2.2. Judge the boundary objects for the target object of the purification unit assembly type.

[0156] In a possible implementation manner, for the target object of the purification unit assembly type, the electronic device can determine the boundary objects from the target object according to the second positional relationship between the purification unit and the purification fan, the third positional relationship between the purification unit and the habitable space, and the fourth positional relationship between the purification fan and the habitable space. Specifically, when the electronic device judges the boundary objects for the target object of the purification unit assembly type, it can be divided into two cases according to whether both the purification unit and the purification fan are located within the habitable space.

[0157] 2.2.1. Both the purification unit and the purification fan are located within the habitable space.

[0158] See Figure 16 , which shows a schematic diagram of a boundary object of a purification unit assembly type provided by the embodiment of the present application. As Figure 16As shown, the target objects of the purifier component type may include the fresh air pipeline of the purification unit, the purification unit, the purification fan, the test exhaust circuit, and the exhaust circuit isolation valve. Among them, the purification unit is equipped with a high-efficiency filter and an iodine filter, which are used to filter the radioactive aerosol and radioactive iodine released during a radioactive air pollution accident. To maintain the availability of the purification unit, technicians need to regularly conduct availability tests on the purification unit. When conducting the availability test, technicians usually inject various tracers into the pipeline upstream of the purification unit to test the functions of the purification unit through the tracers. During the functional test, to prevent the gas downstream of the purification unit from being discharged into the habitable area, technicians can close the valve between the downstream of the purification unit and the return air chamber during the test and open the exhaust circuit isolation valve to discharge the gas downstream of the purification unit to the atmosphere outside the habitable area through the test exhaust circuit. Technicians can close the test exhaust circuit isolation valve during the period when the functional test is not being performed.

[0159] In Figure 16 Among the target objects of the purifier component type shown, the exhaust circuit isolation valve, the purification unit, and the purification fan are all located in the habitable space, and there are also some pipelines of the fresh air pipeline of the purification unit and the test exhaust circuit located in the habitable space. Further, the air transmitted by this target object will first pass through the purification unit and then reach the purification fan, that is, the purification fan is arranged downstream of the purification unit. Thus, it can be seen that in Figure 16 Among the target objects shown, the purification fan is not directly connected to the geotechnical boundary, and the air in the purification fan is all pollution-free air filtered by the purification unit. Therefore, the probability of the purification fan leaking radioactive air pollutants is relatively low, and the electronic device can identify the purification unit, the exhaust circuit isolation valve, the pipeline section between the purification unit and the geotechnical boundary, and the pipeline section between the exhaust circuit isolation valve and the geotechnical boundary in the target object as boundary objects.

[0160] Since the return air chamber in a building is also a type of habitable space, when the target object is deployed in the habitable space, there can be two different deployment methods. Among them, Figure 16 Figure a in Figure 16 shows a schematic diagram of deploying the purifier component in the return air chamber provided by an embodiment of the present application. As shown in Figure 16 Figure a, the exhaust circuit isolation valve, the purification unit, and the purification fan are all located in the return air chamber, and there are also some pipelines of the fresh air pipeline of the purification unit and the test exhaust circuit located in the return air chamber. Among them, Figure 16 Figure b in

[0161] SeeFigure 17 , showing a schematic diagram of the boundary objects of another type of purifier assembly provided by the embodiments of the present application. Compared with Figure 16 b in Figure 17 In the shown target object, the air transmitted by the target object will first pass through the purification fan and then reach the purification unit, that is, the purification fan of the target object is arranged upstream of the purification unit. In this case, the air inside the purification fan is the air that may be contaminated without being filtered by the purification unit, that is, there is also a certain probability of radioactive leakage in the purification fan. Therefore, for Figure 17 the shown target object, the electronic device can identify the purification fan, purification unit, exhaust circuit isolation valve, the pipeline part between the purification unit and the geotechnical boundary, and the pipeline part between the exhaust circuit isolation valve and the geotechnical boundary in the target object as boundary objects.

[0162] 2.2.2. Both the purification unit and the purification fan are located outside the habitable space.

[0163] See Figure 18 , showing a schematic diagram of the boundary objects of another type of purifier unit assembly provided by the embodiments of the present application. In Figure 18 In the shown target object of the purifier unit assembly type, each purifier unit assembly such as the exhaust circuit isolation valve, purification unit, and purification fan is located outside the habitable space. In addition, since all the purifier unit assemblies are located outside the habitable space, and the purification fan is arranged upstream of the purification unit. In addition, an isolation valve is arranged in the pipeline part between the purification unit and the geotechnical boundary, and a return air filter pipeline is connected between the geotechnical boundary and the upstream of the purification fan. For Figure 18 the shown target object, the electronic device can identify the pipeline part between the purification unit and the geotechnical boundary, the isolation valve on the pipeline part between the purification unit and the geotechnical boundary, and the pipeline part between the purification unit and the exhaust circuit isolation valve.

[0164] See Figure 19 , showing a schematic diagram of the boundary objects of another type of purifier assembly provided by the embodiments of the present application. Compared with Figure 18 , Figure 19 In the shown target object, the purification fan is arranged downstream of the purification unit. Therefore, the electronic device can identify the pipeline part between the purification unit and the geotechnical boundary, the isolation valve on the pipeline part between the purification unit and the geotechnical boundary, the pipeline part between the fresh air pipeline and the exhaust circuit isolation valve, the exhaust circuit isolation valve, and the purification fan, etc. as boundary objects.

[0165] Through the method provided in this embodiment, for a target object of the purification machine component type, since the electronic device can determine a boundary object from the target object based on the second positional relationship between the purification unit and the purification fan, the third positional relationship between the purification unit and the inhabitable space, and the fourth positional relationship between the purification fan and the inhabitable space, the method provided in this embodiment can improve the recognition accuracy of the boundary object of the purification machine component type by the electronic device.

[0166] 2.3. Perform boundary object determination on the target object of the compressed air supply equipment type.

[0167] In a possible implementation, the target object of the ventilation system type may further include a target object of the compressed air supply equipment type. Since the target object of the compressed air supply equipment type is usually arranged outside the inhabitable space, the electronic device can identify the pipeline part between the compressed air tank in the target object and the geotechnical boundary of any inhabitable space as the boundary object of the ventilation system type corresponding to the inhabitable space.

[0168] 2.4. Perform boundary object determination on the target object of the air circulation pipeline type.

[0169] In a possible implementation, the target object of the emergency ventilation system type may further include a target object of the air circulation pipeline type. Specifically, for the target object of the air circulation pipeline type, if the number of times the target object crosses the geotechnical boundary is greater than or equal to the number threshold, that is, the inhabitable spaces connected by the target object are distributed at different positions in the building, the electronic device can identify the pipeline part of the air circulation pipeline type target object outside the geotechnical boundary as the boundary object of the ventilation system type corresponding to the inhabitable space.

[0170] S1023. If the object type of the target object is the pipeline type and the target object has a connection relationship with any inhabitable space, then identify the target object as the boundary object corresponding to the inhabitable space.

[0171] In this embodiment, for a target object of the pipeline type, if there is a connection relationship between the target object and any inhabitable space, the electronic device can identify the target object as the boundary object corresponding to the inhabitable space. If there is no connection relationship between the target object of the pipeline type and any inhabitable space, the electronic device can determine that the target object is not a boundary object. Among them, the boundary objects of the pipeline type may include boundary objects of the high-pressure pipeline type and boundary objects of the normal-pressure pipeline type. Specifically, the boundary objects of the high-pressure pipeline type may include, but are not limited to, chilled water pipelines, drinking water pipelines, fire water pipelines, compressed air pipelines, etc. that have a connection relationship with any inhabitable space. The boundary objects of the normal-pressure pipeline type include, but are not limited to, sewage pipelines that have a connection relationship with any inhabitable space.

[0172] Figure 20 The figure shows a specific implementation flowchart of a leakage judgment method S103 for the pressure boundary of a habitable space provided in the third embodiment of the present application. Refer to Figure 20 compared with Figure 1 the above embodiment, in the leakage judgment method S103 for the pressure boundary of a habitable space provided in this embodiment, S103 includes: S1031 to S1033, which are specifically described in detail as follows:

[0173] S1031. If the object type of the boundary object is a ventilation system type, determine the leakage judgment conditions and index data corresponding to the boundary object based on the equipment type to which the boundary object belongs in the ventilation system, and determine the leakage level corresponding to the boundary object according to the index data and the leakage judgment conditions.

[0174] In this embodiment, after the electronic device determines the boundary object corresponding to the habitable space, for the boundary object of the ventilation system type, the electronic device can first determine whether the ventilation system to which the boundary object belongs is a ventilation system serving the habitable space. Specifically, if a ventilation system is used to perform ventilation operations on the habitable space, then the ventilation system is an emergency ventilation system serving the habitable space; if a ventilation system is used to perform ventilation operations on a non-habitable space, then the ventilation system is a ventilation system serving the non-habitable space.

[0175] For the boundary object of the emergency ventilation system type serving the habitable space, the electronic device can determine the leakage judgment conditions and index data corresponding to the boundary object based on the equipment type to which the boundary object belongs in the ventilation system, and determine the leakage level corresponding to the boundary object according to the index data and the leakage judgment conditions. Specifically, the equipment types in the emergency ventilation system serving the habitable space can include a fresh air duct type, an air circulation duct type, a purifier component type, and a compressed air supply equipment type. For the boundary object with the equipment type of the fresh air duct type, the index data corresponding to the boundary object can be the number of isolation valves and the first positional relationship between each isolation valve and the habitable space. For the boundary object with the equipment type of the air circulation duct type, the index data corresponding to the boundary object can be the pipe length. For the boundary object with the equipment type of the purifier component type, the index data corresponding to the boundary object can be the second positional relationship between the purification unit and the purification fan, the third positional relationship between the purification unit and the habitable space, and the fourth positional relationship between the purification fan and the habitable space.

[0176] Among them, for the boundary objects of the compressed air supply equipment type, since the boundary objects are mainly the pipeline parts between the compressed air tank and the geotechnical boundary of any inhabitable space, and the medium pressure value in this pipeline part is often greater than the environmental pressure value of the surrounding environment, that is, this pipeline part is usually in a positive pressure state and is a positive pressure boundary object. Therefore, the electronic device can determine that the leakage level corresponding to this boundary object is a low-risk level. For the boundary objects of the fresh air pipeline type, the air circulation pipeline type, and the purifier component type, since the situation involved is relatively complex and it is necessary to judge in combination with the positional relationship of each component in the boundary object, please refer to the content in the fourth embodiment of this application.

[0177] For the boundary objects of the ventilation system type serving non-inhabitable spaces, since this part of the boundary objects is mainly composed of the equipment located in the inhabitable space in the ventilation system, such as all the ventilation pipelines and components located in the inhabitable space in this ventilation system. Therefore, for the boundary objects of the ventilation system type serving non-inhabitable spaces, the electronic device can determine the leakage level corresponding to the boundary object according to the magnitude relationship between the medium pressure value inside the pipeline part of the boundary object and the environmental pressure value of the inhabitable area where it is located. Specifically, when the medium pressure value inside the pipeline part of the boundary object is less than the environmental pressure value of the inhabitable area where it is located, that is, the boundary object is in a positive pressure state and is a positive pressure boundary object, the electronic device can determine that the leakage level corresponding to this boundary object is a low-risk level; when the medium pressure value inside the pipeline part of the boundary object is greater than or equal to the environmental pressure value of the inhabitable area where it is located, that is, the boundary object is in a negative pressure state and is a negative pressure boundary object, the electronic device can determine that the leakage level corresponding to this boundary object is a medium-risk level or a high-risk level.

[0178] Taking the ventilation system serving the cable layer in the M310 unit as an example, this ventilation system can provide appropriate ventilation services for the cables, storage batteries, reactor protection system equipment, and other related equipment installed in the cable layer. Therefore, this ventilation system needs to operate continuously to provide appropriate ventilation conditions and environmental temperature for the cable layer. Refer to Figure 21 , which shows a schematic diagram of a ventilation system for a cable layer provided by an embodiment of the present application. As Figure 21 shown, the ventilation fan of this ventilation system can be arranged in the first room of the inhabitable area to perform ventilation operations for the first room. Further, since the ventilation pipeline of this ventilation system needs to pass through the first room and the second room to reach the cable layer, and both the first room and the second room are inhabitable spaces, the ventilation fan and the ventilation pipeline located in the first room in this ventilation system both belong to the boundary objects of the ventilation system type of the first room; the ventilation pipeline located in the second room in this ventilation system belongs to the boundary objects of the ventilation system type of the second room.

[0179] For the ventilation duct in the first room, since this part of the duct is connected to the inlet of the air change fan, due to the suction of the fan, the medium pressure value in the ventilation duct before the air change fan in the first room is less than the environmental pressure value in the habitable area of the main control room, that is, this part of the boundary object is in a positive pressure state and is a positive pressure boundary object. Therefore, the leakage level of the ventilation duct before the air change fan can be a low-risk level. The medium pressure in the ventilation duct after the air change fan is greater than the environmental pressure value in the habitable area of the main control room, and this part of the boundary object is in a negative pressure state and is a negative pressure boundary object, and the negative pressure value is relatively large. Therefore, the leakage level of the ventilation duct after the air change fan is a high-risk level. The ventilation duct in the second room is connected to the outlet of the air change fan. Therefore, the medium pressure value in the ventilation duct in the second room is greater than the environmental pressure value in the main control room, that is, this boundary object is in a negative pressure state and is a negative pressure boundary object, and the negative pressure value is relatively large. Therefore, the leakage level of the ventilation duct in the second room can be a high-risk level.

[0180] S1032. If the object type of the boundary object is a pipe type, then based on the pressure difference between the medium pressure value inside the boundary object and the environmental pressure value of the environment where the boundary object is located, determine the leakage level corresponding to the boundary object.

[0181] In this embodiment, for the object type of the boundary object being a pipe type, the electronic device can determine the leakage level corresponding to the boundary object according to the pressure difference between the medium pressure value inside the boundary object and the environmental pressure value of the environment where the boundary object is located. Among them, the boundary object of the pipe type can include the boundary object of the high-pressure pipe type and the boundary object of the normal-pressure pipe type.

[0182] A high-pressure pipe refers to a pipe whose internal medium pressure value is much greater than 0.1 MPa. High-pressure pipes can be used to transport high-pressure fluid media. For the boundary object of the high-pressure pipe type, since its internal medium pressure value is much greater than 0.1 MPa, and the standard atmospheric pressure value is 0.1 MPa, the pressure difference between the internal medium pressure value of the boundary object of the high-pressure pipe type and the environmental pressure value of the environment where the boundary object is located is relatively large, much greater than the preset pressure difference. Further, since the boundary object of the high-pressure pipe type is usually a pressure-bearing pipe with relatively strict design and manufacturing standards, the leakage probability of the internal medium is relatively low. To put it another way, even if the boundary object of the high-pressure pipe type leaks, due to the relatively large internal medium pressure value, the medium pressure value at the leakage point will drop rapidly or there will be an obvious leakage sound when the boundary object of the high-pressure pipe type leaks, which is easily detected by technicians. Therefore, the electronic device can determine that the leakage level of the boundary object of the high-pressure pipe type is a low-risk level.

[0183] An atmospheric pressure pipeline refers to a pipeline that operates under atmospheric pressure. Therefore, the pressure difference between the medium pressure value inside the atmospheric pressure pipeline and the ambient pressure value of the environment where it is located is easily affected by changes in the ambient pressure of the boundary object. For example, if the ambient pressure value in a habitable space is greater than the standard atmospheric pressure value, then the medium pressure value inside the sewage pipe in this habitable space is less than the ambient pressure value of the environment where it is located, that is, the pressure difference between the medium pressure value and the ambient pressure value in the habitable area is less than 0, and the sewage pipe is a positive pressure boundary. At this time, the electronic device can determine that this sewage pipeline is of a low risk level. However, when the door of this habitable space is opened for a long time, a short-term pressure loss may occur in this habitable space. At this time, the ambient pressure value in the habitable space drops suddenly, which may cause the medium pressure value inside the sewage pipe to be greater than the ambient pressure value of the environment where it is located, that is, the pressure difference between the medium pressure value and the ambient pressure value is greater than 0, and the sewage pipe is a negative pressure boundary. At this time, the electronic device can determine that this sewage pipeline is of a medium risk level.

[0184] Therefore, for boundary objects of the atmospheric pressure pipeline type, the electronic device can continuously obtain the medium pressure value inside the boundary object and the ambient pressure value of the environment where the boundary object is located, and continuously update the pressure difference between the boundary object and the environment where it is located based on the latest obtained medium pressure value and ambient pressure value, and continuously update the leakage level corresponding to the boundary object of the atmospheric pressure pipeline type according to the pressure difference. Specifically, for boundary objects of the atmospheric pressure pipeline type, when the pressure difference between the medium pressure value and the ambient pressure value in the habitable area is greater than 0 and the boundary object is in a positive pressure state, the electronic device can determine that this boundary object is of a low risk level. For boundary objects of the atmospheric pressure pipeline type, when the pressure difference between the medium pressure value and the ambient pressure value is less than or equal to 0 and the boundary object is in a negative pressure state, the electronic device can determine that this boundary object is of a medium risk level.

[0185] S1033. If the object type of the boundary object is of the geotechnical type, then query the preset grade mapping relationship based on the object identifier of the boundary object to determine the leakage grade corresponding to the boundary object.

[0186] In this embodiment, for boundary objects of the geotechnical type, the electronic device can query the preset grade mapping relationship according to the object identifier of the boundary object to determine the basic grade corresponding to this geotechnical type of boundary object. Then, the electronic device can also adjust the basic grade according to information such as the leakage nature, pressure difference magnitude, sealing parameters, sealing ability, sealing failure probability, and the number of components included in the boundary object to determine the leakage grade corresponding to this boundary object. Among them, the grade mapping relationship may include the object identifiers of multiple different geotechnical type boundary objects and the basic grades respectively corresponding to each object identifier. Refer to Table 3 below, which is a grade mapping relationship table provided by an embodiment of the present application.

[0187]

[0188]

[0189] Table 3 Hierarchical Mapping Relationship Table

[0190] Specifically, if an object of a certain geotechnical type usually has an internal leakage property or its pressure difference state is usually a negative pressure state, since unfiltered internal leakage is the main reason for the increase in the internal radiation dose of the inhabitable space, the leakage level of the object of this geotechnical type can be medium risk level or above. If the pressure difference between the internal medium pressure value and the environmental pressure value of the external environment of an object of a certain geotechnical type is greater than the difference threshold, the leakage level of the object of this geotechnical type can be medium risk level or above.

[0191] If an object of a certain geotechnical type has one or more of the following three situations: the sealing surface area is greater than the area threshold, the number of leakage points where leakage may occur is greater than the leakage point threshold, and the complexity of the process is above high complexity, the electronic device can raise one level on its basic level. When the sealing ability of the object of the geotechnical type is relatively high, the electronic device can lower one level on its basic level; correspondingly, when its sealing ability is relatively low, the electronic device can raise one level on its basic level. When the probability of sealing failure of the object of the geotechnical type is relatively high, the electronic device can raise one level on its basic level; correspondingly, when its probability of sealing failure is relatively low, the electronic device can lower one level on its basic level. When the number of components included in the object of the geotechnical type is relatively large, the electronic device can raise one level on its basic level; when the number of components included is relatively small, the electronic device can lower one level on its basic level. When the boundary object is a boundary object located in the buffer space, the electronic device can lower one level on its basic level.

[0192] Taking the floor drain in the return air chamber or the air supply fan room in the inhabitable space as an example, the electronic device can determine that the basic level of the floor drain is the medium risk level by querying the level mapping table. Since the environmental pressure value in the return air chamber or the air supply fan room is usually much smaller than the standard atmospheric pressure value, that is, the return air chamber or the air supply fan room is always in a large negative pressure state, and the floor drain usually relies on the water seal to achieve sealing isolation. It is very easy to cause the sealing to fail due to liquid evaporation or lack of timely liquid addition. The electronic device can raise one level on its basic level. In summary, the final leakage level of this floor drain can be the high risk level. Therefore, for this floor drain, the measure that the technician needs to take is to ensure and maintain the water seal height. After the electronic device determines the leakage level corresponding to this floor drain, if the area to be identified where the floor drain is located is an area to be built, the leakage prompt information generated by the electronic device can include the water seal height that needs to be met in the design link and the specific operations that need to confirm the water seal effectiveness in the construction link. If the area to be identified where the floor drain is located is an existing area, the leakage prompt information generated by the electronic device can include the frequency of the technician's inspection of this floor drain and the frequency of the liquid addition operation for this floor drain to maintain the water seal height of this floor drain.

[0193] Through the method provided in this embodiment, since the electronic device determines the leakage level corresponding to the boundary object according to the leakage judgment condition corresponding to the object type of the boundary object, therefore, the method provided in this embodiment enables the electronic device to specifically judge the leakage level of each boundary object, thereby improving the accuracy of the leakage level determined by the electronic device.

[0194] Figure 22 The specific implementation flowchart of a leakage judgment method S1031 for the pressure boundary of an inhabitable space provided in the fourth embodiment of the present application is shown. Refer to Figure 22 , compared with Figure 20 In the embodiment described above, S1031 in a leakage judgment method for the pressure boundary of an inhabitable space provided in this embodiment includes: S10311 to S10313, which are specifically described in detail as follows:

[0195] S10311. If the device type of the boundary object is the fresh air duct type, determine the leakage level corresponding to the fresh air duct assembly according to the number of valves included in the boundary object and the first positional relationship between each isolation valve and the inhabitable space.

[0196] In this embodiment, for the boundary objects of the ventilation system type, the electronic device can determine the leakage judgment conditions and index data corresponding to the boundary objects according to the device type to which the boundary objects belong in the ventilation system. Among them, the device types in the ventilation system can include, but are not limited to, fresh air duct types, air circulation duct types, and purifier component types. For the boundary objects of the fresh air duct type, the electronic device can determine the leakage level corresponding to the fresh air duct component according to the number of valves of the isolation valves included in the boundary objects and the first positional relationship between each isolation valve and the inhabitable space.

[0197] In a possible implementation manner, for the boundary objects of the fresh air duct type in the ventilation system, according to the number of valves of the isolation valves they contain, they can be divided into boundary objects of the single-valve fresh air duct type and boundary objects of the double-valve fresh air duct type. Therefore, for the boundary objects of the fresh air duct type, the electronic device can first determine their corresponding types according to the number of valves of the isolation valves included in the boundary objects. Among them, when there is only one isolation valve in the boundary objects of the fresh air duct type, the electronic device can determine that the current boundary object is a boundary object of the single-valve fresh air duct type. The boundary objects of the single-valve fresh air duct type can include isolation valves and the ducts starting from the location of the isolation valves until the connection with the boundary surface. When there are multiple isolation valves in the boundary objects of the fresh air duct type, the electronic device can determine that the current boundary object is a boundary object of the double-valve fresh air duct type. And the boundary objects of the double-valve fresh air duct type need to be determined according to the positional relationship between each isolation valve and the inhabitable space, that is, when the positional relationship between the isolation valve and the inhabitable space is different, the boundary objects of the double-valve fresh air duct type may be different. Therefore, when the electronic device determines the leakage level corresponding to the boundary objects of the fresh air duct type, it can be divided into two cases: boundary objects of the single-valve fresh air duct type and boundary objects of the double-valve fresh air duct type.

[0198] 1. Determine the leakage level of the boundary objects of the single-valve fresh air duct type.

[0199] In a possible implementation manner, for the boundary objects of the single-valve fresh air duct type, the electronic device can determine the leakage level corresponding to the boundary objects according to the first positional relationship between the isolation valve and the inhabitable space. Refer to Figure 7 , which shows a schematic diagram of a boundary object of the single-valve fresh air duct type provided by an embodiment of the present application. Among them, Figure 7Among the boundary objects of the fresh air duct type shown, there is exactly one isolation valve, and the isolation valve in the boundary object is located outside the habitable space. For the boundary object of the single-duct fresh air duct type, since this fresh air duct is connected to the return air chamber in the habitable space, the medium pressure value in the duct between the isolation valve of this boundary object and the boundary surface is usually lower than the ambient pressure value of the surrounding environment, that is, the duct at this location is in a negative pressure state, and the pressure difference between the medium pressure value in the duct at this location and the external ambient pressure value can reach -500 Pa. Therefore, this boundary object belongs to an internal leakage boundary and there is a risk of leakage into the interior of the habitable area. Further, due to the large pressure difference of this boundary object, as long as there is a very small leakage point, a large leakage volume may occur in this boundary object. To sum up, for the boundary object of the single-duct fresh air duct type, when the isolation valve is located outside the habitable space, the electronic device can identify the leakage level of this boundary object as a high-risk level, and the electronic device can also classify the importance of this boundary object as a critical category.

[0200] See Figure 8 , which shows a schematic diagram of another boundary object of the single-duct fresh air duct type provided by the embodiment of the present application. As Figure 8 shown, similarly, the dark line part around the habitable space is used to represent the pressure boundary corresponding to the habitable space. Among the boundary objects of this fresh air duct type, there is exactly one isolation valve, and the isolation valve in the boundary object is located inside the habitable space, that is, this boundary object is a boundary object of the single-duct fresh air duct type and the isolation valve is located inside the habitable space. For the boundary object of the single-duct fresh air duct type, when the isolation valve is located inside the habitable space, the pressure difference between the medium pressure value inside the fresh air duct between the isolation valve and the boundary surface and the ambient pressure value of the environment where this fresh air duct is located mainly depends on the pressure distribution in the habitable space. Therefore, for this boundary object, since the duct part of this boundary object is located outside the habitable space and the isolation valve of this boundary object is located inside the habitable space, that is, the duct part and the isolation valve of this boundary object are located at different positions, the electronic device can respectively determine the leakage level of the duct part of this boundary object and the leakage level of the isolation valve.

[0201] Specifically, for Figure 8 the duct part of the boundary object shown, when the ambient pressure value in the habitable space where this boundary object is located is greater than the atmospheric pressure value outside the geotechnical boundary of the habitable space, further, as Figure 8As the pipeline part of the boundary object is connected to the pipeline located outside the habitable space, the medium pressure value of the pipeline part of the boundary object is less than the environmental pressure value in the habitable space, that is, the pipeline part of the boundary object is in a positive pressure state. At this time, the leakage level of the pipeline part of the boundary object can be a low-risk level. When the environmental pressure value in the habitable space where the boundary object is located is less than or equal to the atmospheric pressure value outside the geotechnical boundary of the habitable space, since the pipeline part of the boundary object is located outside the habitable space, the medium pressure value of the pipeline part of the boundary object is greater than or equal to the environmental pressure value in the habitable space, that is, the pipeline part of the boundary object is in a negative pressure state. At this time, the leakage level of the pipeline part of the boundary object can be a medium-risk level.

[0202] For Figure 8 Regarding the isolation valve of the boundary object shown, since one side of the isolation valve is the pipeline outside the habitable space and the other side is connected to the return air chamber in the habitable space, the pressure difference between the two sides of the isolation valve is large. Therefore, the electronic device can identify the leakage level of the isolation valve as a high-risk level. To sum up, since Figure 8 the boundary object shown contains an isolation valve with a high-risk leakage level, therefore, Figure 8 the overall leakage level of the boundary object of the single-channel valve fresh air pipeline type shown can be a high-risk level.

[0203] In a possible implementation, when there are multiple isolation valves in the boundary object, that is, when the boundary object is of the double-channel valve fresh air pipeline type, the electronic device determines the leakage level corresponding to the boundary object according to the pressurized pipeline distribution information between the isolation valves and the first positional relationship between each isolation valve and the habitable space.

[0204] In a possible implementation, when there are two isolation valves in the boundary object and there is no pressurized pipeline between the two isolation valves, the electronic device can determine the leakage level corresponding to the boundary object according to the first positional relationship between each isolation valve and the habitable space.

[0205] 2. Determine the leakage level of the boundary object of the double-channel valve fresh air pipeline type.

[0206] When determining the leakage level corresponding to the boundary object of the double-channel valve fresh air pipeline type, the electronic device can divide the boundary object of the double-channel valve fresh air pipeline type into two cases according to whether the target object contains a pressurized pipeline.

[0207] 2.1. The target object does not contain a pressurized pipeline.

[0208] In Figure 9Among the boundary objects shown, since multiple series-connected isolation valves only reduce the probability of air leakage from the fresh air duct outside the first isolation valve into the habitable space, but the duct between the second isolation valve and the geotechnical boundary communicates with the return air chamber in the habitable space, there is still a relatively high risk of internal leakage, and the leakage level can be a high-risk level. Therefore, the electronic device can identify the leakage level of this boundary object as a high-risk level. When the electronic device determines that there is a Figure 9 boundary object shown in the area to be identified, if the area to be identified is an area to be built, the electronic device can generate leakage prompt information including position adjustment information. Among them, Figure 9 the position adjustment information corresponding to the boundary object shown can be used to indicate that it is recommended that the technician adjust the second isolation valve into the habitable space.

[0209] In Figure 10 the boundary object shown, since the two isolation valves are respectively located on both sides of the geotechnical boundary of the habitable space, the probability of both isolation valves failing simultaneously is relatively low. Therefore, the leakage level of the second isolation valve can be a medium-risk level. Further, since the leakage risk of the duct part in this boundary object is relatively low whether it is in a positive pressure state or a negative pressure state, it can be identified as a medium-risk level or a low-risk level. Therefore, the electronic device can identify the overall leakage level of this boundary object as a medium-risk level.

[0210] In Figure 11 the boundary object shown, the two series-connected isolation valves are both located in the habitable space, and the probability of both isolation valves failing simultaneously when they are connected in series is relatively low. Thus, the electronic device can identify the leakage levels of both isolation valves as medium-risk levels. Whether the duct part in the boundary object is in a positive pressure state or a negative pressure state depends on the pressure difference between the medium pressure value inside the duct part and the ambient pressure value of the environment where the duct is located, and it can be a medium-risk level or a low-risk level. Therefore, the electronic device can identify the leakage level of the duct part of this boundary object as a medium-risk level. To sum up, since Figure 11 in the boundary object shown, the leakage levels of the isolation valve and the duct part can be a medium-risk level or a low-risk level, the leakage level of this boundary object is a medium-risk level.

[0211] In a possible implementation, when there are two isolation valves at the boundary object and there is a pressurization pipeline between the two isolation valves, the electronic device can determine the leakage level corresponding to the boundary object according to the first positional relationship between each isolation valve and the inhabitable space, and the third positional relationship between the pressurization pipeline and the inhabitable space. In the actual use process, it is found that when the gas source in the pressurization pipeline is unfiltered compressed air, since the compressed air is the air outside the inhabitable space, the compressed air may also be contaminated after a radioactive contamination accident. Further, filling compressed air through the pressurization pipeline will increase the pressure difference on both sides of the second isolation valve in the boundary object, thereby increasing the internal leakage of the second isolation valve, and further increasing the risk of contamination of the inhabitable space. Therefore, in the actual use process, it is not recommended to directly use compressed air as the gas source of the pressurization pipeline of the ventilation system. In contrast, after a radioactive contamination accident, using filtered compressed air or the air in the air supply chamber as the pressurization gas source can avoid the above risks, thereby improving the isolation effect of the double isolation valve in the ventilation system. Therefore, the gas source in the pressurization pipeline in the embodiment of the present application can be filtered compressed air or the air in the air supply chamber.

[0212] 2.2. The target object includes a pressurization pipeline.

[0213] 2.2.1. The pressurization pipeline is located outside the inhabitable space.

[0214] Figure 12 In the shown boundary object, regardless of whether the boundary object includes a pressurization pipeline, since the space between the first isolation valve and the second isolation valve is connected to the pressurization pipeline and filled with clean air at a relatively high pressure, when the first isolation valve leaks outward, it prevents external contaminated air from entering the chamber. Although the second isolation valve is always in a negative pressure state, the leaked air is clean air, so the leakage level is a low-risk level. However, the pipeline between the second isolation valve and the geotechnical boundary is connected to the return air chamber in the inhabitable space, so there is still a relatively large internal leakage risk, and the leakage level can be identified as a high-risk level. To sum up, the electronic device can identify the leakage level of this boundary object as a high-risk level. Further, since the positive pressure state of this boundary object is mainly achieved by filling air through the pressurization pipeline, the electronic device can set the importance level of this boundary object as an important level. When the electronic device determines that there is a Figure 12 shown boundary object in the area to be recognized, if the area to be recognized is an area to be built, the electronic device can generate a leakage prompt message including position adjustment information. Among them, Figure 12 the position adjustment information corresponding to the shown boundary object can be used to indicate that it is recommended that the technician adjust the second isolation valve into the inhabitable space, or adjust all three of the first isolation valve, the pressurization pipeline, and the second isolation valve into the inhabitable space to reduce the leakage level of the boundary object.

[0215] Figure 13 Among the boundary objects shown, regardless of whether the boundary object contains a pressurization pipeline, since the boundary object is connected to a pressurization pipeline, the medium pressure value inside the boundary object is greater than the ambient pressure value of the inhabitable space. That is, when the boundary object leaks, clean air usually leaks into the inhabitable space. Therefore, the boundary object is a low-risk negative-pressure boundary object or an internal-leak boundary object. In summary, the electronic device can identify the leakage level of the boundary object as a low-risk level. In addition, since the negative-pressure state of the boundary object is mainly achieved by injecting air through the pressurization pipeline, the electronic device can identify the importance level of the boundary object as an important level and needs to pay attention to the effectiveness of pressurization.

[0216] Furthermore, in Figure 13 Among the boundary objects shown, even though the first isolation valve and the pipeline section between the first isolation valve and the geotechnical boundary are not boundary objects, when the first isolation valve and / or the pipeline section between the first isolation valve and the geotechnical boundary leaks, it will affect the pressure value of pressurization. Therefore, in order to reduce the leakage risk, the electronic device can generate maintenance frequency information. Among them, the maintenance frequency information can be used to prompt technicians to manage the first isolation valve, the second isolation valve, the pipeline section between the first isolation valve and the geotechnical boundary, and the pressurization circuit in the management mode corresponding to the low-risk-level boundary object.

[0217] 2.2.2. The pressurization pipeline is located in the inhabitable space.

[0218] Figure 14 Among the boundary objects shown, since the boundary object consists of three parts: the pipeline section of the pressurization pipeline located in the inhabitable space, the second isolation valve, and the pipeline section between the second isolation valve and the geotechnical boundary, the electronic device can respectively determine the leakage levels corresponding to each part in the boundary object and determine the overall leakage level of the boundary object according to the leakage levels corresponding to each part in the boundary object. For the second isolation valve and the pipeline section between the second isolation valve and the geotechnical boundary in the boundary object, although they are negative-pressure boundaries because they are filled with filtered air at a relatively high pressure, they are of low-risk level, and the electronic device can identify their leakage levels as low-risk levels.

[0219] For Figure 14 Regarding the part of the pressurization pipeline in the boundary object shown, when the air source of the pressurization pipeline is the air in the air supply chamber, since the air in the air supply chamber has undergone a filtration operation through the purification unit, at this time, the air in the pressurization pipeline is all filtered air, and the electronic device can identify the leakage level corresponding to the part of the pressurization pipeline in the boundary object as a low-risk level. In summary, in the case where the boundary object does not contain a filter on the pressurization pipeline, since the leakage levels of all parts of the boundary object are low-risk levels, the electronic device can identify the overall leakage level corresponding to the boundary object as a low-risk level.

[0220] When the gas source of the pressurization pipeline is compressed air and the filter on the pressurization pipeline is located in the habitable space, since the medium inside the pipeline section from the geotechnical boundary to the filter in the pressurization pipeline is unfiltered air and there may be radioactive air pollutants, the electronic device can identify the leakage level of the pressurization pipeline section from the geotechnical boundary to the filter in the pressurization pipeline as a high-risk level and the leakage level of the pressurization pipeline after the filter as a low-risk level. In summary, when the boundary object includes the filter on the pressurization pipeline, since there is a part of the pressurization pipeline in the boundary object with a high-risk leakage level, the electronic device can identify the leakage level corresponding to the entire boundary object as a high-risk level.

[0221] When the filter on the pressurization pipeline is located outside the habitable space, that is, when the boundary object does not include the filter on the pressurization pipeline, since the internal medium in the pressurization pipeline in the habitable space is filtered air at this time, the electronic device can identify the leakage level corresponding to the part of the pressurization pipeline in the boundary object as a low-risk level. In summary, when the boundary object does not include the filter on the pressurization pipeline, since the leakage levels of all parts of the boundary object are low-risk levels, the electronic device can identify the leakage level corresponding to the entire boundary object as a low-risk level.

[0222] Figure 15 The shown boundary object is composed of the part of the pressurization pipeline located in the habitable space, the second isolation valve, the first isolation valve, and the pipeline section between the second isolation valve and the geotechnical boundary. Since both the second isolation valve and the first isolation valve in the boundary object are located within the geotechnical boundary surface, and the pressurization pipeline between the second isolation valve and the first isolation valve can perform a pressurization operation on the boundary object, thereby reducing the probability of external air leaking into the habitable space through the fresh air pipeline, the leakage levels of the second isolation valve, the first isolation valve, and the pipeline section between the first isolation valve and the geotechnical boundary in this boundary object are all low-risk levels. Among them, the first isolation valve can be a positive-pressure boundary object. For the pipeline section between the primary isolation valve and the geotechnical boundary, the electronic device can judge whether this pipeline section is a positive-pressure boundary object or a negative-pressure boundary object according to the pressure difference between the medium pressure value inside this pipeline section and the environmental pressure value of the environment where this pipeline section is located.

[0223] For Figure 15 the part of the pressurization pipeline in the shown boundary object, the specific method for the electronic device to judge the leakage level is the same as Figure 14 the method for judging the leakage level of the pressurization pipeline in the shown boundary object. Please refer to the content in Figure 14 this embodiment, and details will not be repeated here. In summary, for Figure 15For the boundary object shown, when the air source of the pressurized pipeline is the air in the air supply chamber, the electronic device can identify the leakage level corresponding to the entire boundary object as a low-risk level; when the air source of the pressurized pipeline is compressed air and the filter is located within the habitable space, the electronic device can identify the leakage level corresponding to the entire boundary object as a high-risk level; when the air source of the pressurized pipeline is compressed air and the filter is located outside the habitable space, the electronic device can identify the leakage level corresponding to the entire boundary object as a low-risk level.

[0224] Through the method provided in this embodiment, for the target object of the fresh air duct type, since the electronic device can determine the leakage level corresponding to the boundary object according to the number of valves of the isolation valve included in the boundary object and the first positional relationship between each isolation valve and the habitable space, the method provided in this embodiment can improve the recognition accuracy of the leakage level of the boundary object of the fresh air duct type.

[0225] S10312. If the device type of the boundary object is the air circulation duct type, determine the leakage level corresponding to the boundary object based on the pipeline length corresponding to the boundary object of the air circulation duct type.

[0226] In this embodiment, for the boundary object of the air circulation duct type in the ventilation system, since the pipeline length is one of the important factors affecting the leakage probability of the pipeline, the electronic device can determine the leakage level corresponding to the boundary object according to the pipeline length corresponding to the boundary object of the air circulation duct type. Among them, the air circulation ducts in the ventilation system can include the supply air duct and the return air duct.

[0227] In a possible implementation manner, since the habitable spaces in the nuclear power plant may be distributed at different positions in the building, for example, each habitable space is distributed on different floors or there is a certain habitable space independently distributed in a remote location. In this case, if the air supply operation is still performed by the main ventilation unit in the same ventilation system between each habitable space, it may occur that the supply air duct and / or the return air duct cross the geotechnical boundary of different habitable spaces, and the supply air duct and / or the return air duct are relatively long. Therefore, for the boundary object of the air circulation duct type in the ventilation system, the electronic device can determine the leakage level corresponding to the boundary object according to the pipeline length.

[0228] Specifically, for the air supply duct corresponding to a certain habitable space, if the number of times the air supply duct crosses the geotechnical boundary is greater than or equal to the threshold number of times, and the duct length corresponding to the air supply duct is greater than or equal to the first length threshold, the electronic device can identify the leakage level corresponding to the air supply duct as a medium risk level; if the number of times the air supply duct crosses the geotechnical boundary is less than the threshold number of times, and / or the duct length corresponding to the air supply duct is less than the first length threshold, the electronic device can identify the leakage level corresponding to the air supply duct as a low risk level. Among them, since the medium pressure value inside the air supply duct is large, that is, compared with the environment where the air supply duct is located, the medium inside the air supply duct is in a positive pressure state, and the air supply duct is a positive pressure boundary object. Therefore, for the air supply duct, its highest leakage level can be a medium risk level, and the lowest can be a low risk level.

[0229] For the return air duct corresponding to a certain habitable space, if the number of times the return air duct crosses the geotechnical boundary is greater than or equal to the threshold number of times, and the duct length corresponding to the return air duct is greater than or equal to the second length threshold, the electronic device can identify the leakage level corresponding to the return air duct as a high risk level; if the number of times the return air duct crosses the geotechnical boundary is less than the threshold number of times, and / or the duct length corresponding to the return air duct is less than the second length threshold, the electronic device can identify the leakage level corresponding to the return air duct as a medium risk level. Among them, since the medium pressure value inside the return air duct is small, that is, compared with the environment where the return air duct is located, the medium inside the return air duct is in a negative pressure state, and the return air duct is a negative pressure boundary object. Therefore, for the return air duct, its highest leakage level can be a high risk level, and the lowest can be a medium risk level.

[0230] Taking Room L543 in the technical support room of the M310 / CPR1000 nuclear power unit as an example, this room is located alone on the 11.5-meter floor of the plant, while other habitable spaces in the plant are mainly concentrated on the 15.5-meter and 19.4-meter floors. Therefore, the main ventilation unit and the return air chamber of the ventilation system in this plant can be deployed on the 19.4-meter floor. The main ventilation unit in the ventilation system needs to transmit the air at the air supply chamber to Room L543 through the air supply duct, and transmit the air in Room L543 to the return air chamber through the return air duct. Since Room L543 is on the 11.5-meter floor, while the main ventilation unit and the return air chamber are on the 19.4-meter floor, the duct length of the return air duct and the air supply duct of Room L543 can both be greater than 50 meters.

[0231] For the air supply duct of Room L543, since the number of times the air supply duct crosses the geotechnical boundary is at least two, and the duct length is greater than 50 meters and is relatively long. Further, since the air supply duct needs to pass through a non-habitable space to reach Room L543, the electronic device can identify the leakage level of the air supply duct of Room L543 as a medium risk level.

[0232] For the return air duct of Room L543, since the return air duct crosses the geotechnical boundary at least twice and the duct length is greater than 50 meters, which is relatively long. Further, since the return air duct needs to pass through a non - habitable space to reach Room L543, the electronic device can identify the leakage level of the return air duct of Room L543 as a high - risk level.

[0233] When the electronic device determines that there are boundary objects in the area to be built as return air ducts and / or supply air ducts, the electronic device can generate third - position adjustment information. Among them, the third - position adjustment information is used to prompt the technician to arrange the habitable spaces together as much as possible and avoid and reduce the situation that the ventilation system of the habitable space crosses the geotechnical boundary. In addition, the third - position adjustment information can also be used to prompt the technician to shorten the length of the return air duct and / or supply air duct outside the geotechnical boundary, and take measures to enhance the sealing of the return air duct and / or supply air duct outside the habitable space, such as using low - leakage ducts, reducing pipeline leakage components, and hermetically wrapping the air ducts. When the electronic device determines that there are boundary objects in the built - up area as return air ducts and / or supply air ducts, the electronic device can generate inspection frequency information to prompt the staff to regularly check their sealing performance.

[0234] S10313: If the equipment type of the boundary object is a purification machine component type, then based on the second position relationship between the purification unit and the purification fan in the boundary object, the third position relationship between the purification unit and the habitable space, and the fourth position relationship between the purification fan and the habitable space, determine the leakage level corresponding to the boundary object.

[0235] In this embodiment, for the boundary object of the purification machine component type, the electronic device can obtain the second position relationship between the purification unit and the purification fan in the boundary object, the third position relationship between the purification unit and the habitable space, and the fourth position relationship between the purification fan and the habitable space. Then, the electronic device can determine the leakage level corresponding to the boundary object according to the second position relationship, the third position relationship, and the fourth position relationship. Among them, when the electronic device determines the leakage level corresponding to the boundary object of the purification machine component type, it can be divided into two cases according to whether the purification unit and the purification fan are in the habitable space.

[0236] 1. Both the purification unit and the purification fan are located in the habitable space.

[0237] In a possible implementation, Figure 16Among the boundary objects of the purification machine component type shown, the boundary object is mainly composed of a purification unit, an exhaust circuit isolation valve, the pipeline section between the purification unit and the geotechnical boundary, and the pipeline section between the exhaust circuit isolation valve and the geotechnical boundary, and each part constituting the boundary object is located in the inhabitable space. In the event of a radioactive contamination accident, since the purification circuit supply fan in the emergency ventilation system starts, the pressure value inside the exhaust circuit isolation valve is greater than the ambient pressure value of its environment, that is, the exhaust circuit isolation valve is in a positive pressure state, and the exhaust circuit isolation valve is a positive pressure boundary. Therefore, the leakage grade corresponding to the exhaust circuit isolation valve in the boundary object can be a low-risk grade.

[0238] The leakage grades of the pipeline section between the purification unit and the geotechnical boundary and the pipeline section of the test exhaust circuit located in the inhabitable space depend on the magnitude relationship between the internal pressure of the pipeline and the ambient pressure value of the environment where the pipeline is located. For this type of boundary object, the boundary object can be arranged in the return air chamber of the inhabitable space or in other places in the inhabitable space except the return air chamber. Since the ambient pressure value inside the return air chamber is lower than that inside other rooms, the electronic device can determine the leakage grades corresponding to the pipeline section between the purification unit and the geotechnical boundary and the pipeline section of the test exhaust circuit located in the inhabitable space according to whether the boundary object is arranged in the return air chamber.

[0239] Among them, Figure 16 a shown in Figure 16 shows the case where the boundary object is arranged in the return air chamber. In the case shown by a in Figure 16 , the pipeline section between the purification unit and the geotechnical boundary in the boundary object and the pipeline section of the test exhaust circuit located in the return air chamber of the inhabitable space will be in a large negative pressure state, that is, the pipeline section between the purification unit and the geotechnical boundary and the pipeline section of the test exhaust circuit located in the return air chamber of the inhabitable space are negative pressure boundary objects, and the leakage grade corresponding to the geotechnical is a high-risk grade. At this time, since there is a part with a high-risk leakage grade in the boundary object, the overall leakage grade of the boundary object shown in

[0240] can also be a high-risk grade. Figure 16 As shown by b in Figure 16The leakage level of the overall boundary object shown as b in can be a low-risk level or a medium-risk level.

[0241] See Figure 17 , compared with Figure 16 the boundary object shown, because Figure 17 in the boundary object shown, the purification fan is arranged in front of the purification unit, so Figure 17 the boundary object shown also includes a purification fan. Among them, the pipeline part between the purification fan in the boundary object and the geotechnical boundary is in a positive pressure state, which is a positive pressure boundary. Therefore, the leakage level of the pipeline part between the purification fan and the geotechnical boundary is a low-risk level. The pipeline part between the purification fan and the purification unit is in a negative pressure state and the pressure is relatively large, which is a negative pressure boundary with a high-risk level. Therefore, the geotechnical leakage level is a high-risk level.

[0242] Among them, for Figure 17 the exhaust air circuit isolation valve in the boundary object and the pipeline part between the exhaust air circuit isolation valve and the geotechnical boundary, the determination method of the leakage levels of these two parts is the same as that of Figure 16 . Please refer to Figure 16 the specific content in for details and will not be elaborated here.

[0243] In summary, because Figure 17 in the boundary object shown, there is a pipeline part between the purification fan and the purification unit with a high-risk leakage level. Therefore, Figure 17 the overall leakage level of the boundary object shown is a high-risk level.

[0244] In a possible implementation manner, when the electronic device determines that there is Figure 17 the boundary object shown in the area to be built, the electronic device can generate fourth position adjustment information. Among them, the fourth position adjustment information is used to prompt the technician to adjust the purification unit to the upstream of the purification fan to reduce the leakage level of the boundary object. When the electronic device determines that there is Figure 17 the boundary object shown in the built area, the electronic device can generate detection frequency information to prompt the staff to regularly check its sealing performance.

[0245] 2. Both the purification unit and the purification fan are located outside the habitable space.

[0246] In a possible implementation manner, in Figure 18Among the boundary objects of the purification machine component type shown, the boundary object mainly consists of four parts: the pipeline part between the purification unit and the geotechnical boundary, the isolation valve on the pipeline part between the purification unit and the geotechnical boundary, the pipeline part between the purification unit and the exhaust circuit isolation valve, and the exhaust circuit isolation valve. Among them, the pipeline part between the purification unit and the geotechnical boundary, the isolation valve on the pipeline part between the purification unit and the geotechnical boundary, the pipeline part between the purification unit and the exhaust circuit isolation valve, and the exhaust circuit isolation valve are all in a positive pressure state and are positive pressure boundary objects. Therefore, the leakage levels of the four parts, namely the pipeline part between the purification unit and the geotechnical boundary, the isolation valve on the pipeline part between the purification unit and the geotechnical boundary, the pipeline part between the purification unit and the exhaust circuit isolation valve, and the exhaust circuit isolation valve, are all of low risk level. To sum up, in Figure 18 the overall leakage level of the boundary object shown can be of low risk level.

[0247] In Figure 19 Among the boundary objects of the purification machine component type shown, the boundary object mainly consists of five parts: the pipeline part between the purification unit and the geotechnical boundary, the purification fan, the isolation valve on the pipeline part between the purification fan and the geotechnical boundary, the pipeline part between the purification fan and the exhaust circuit isolation valve, and the exhaust circuit isolation valve. Among them, the pipeline part between the purification fan and the geotechnical boundary, the isolation valve on the pipeline part between the purification fan and the geotechnical boundary, the pipeline part between the purification fan and the exhaust circuit isolation valve, and the exhaust circuit isolation valve are all in a positive pressure state and are positive pressure boundary objects. Therefore, the electronic device can identify the leakage levels of the above-mentioned devices as low risk levels. However, the pipeline between the purification unit and the purification fan is a negative pressure boundary with a very large negative pressure. Therefore, the electronic device can identify the leakage level of this part of the pipeline as a high risk level. To sum up, the electronic device can Figure 19 identify the overall leakage level of the boundary object shown as a high risk level.

[0248] In a possible implementation manner, when the electronic device determines that there is a Figure 19 boundary object shown in the area to be built, the electronic device can generate fourth position adjustment information. Among them, the fourth position adjustment information is used to prompt the technician to adjust the purification fan to the upstream of the purification unit to reduce the leakage level of the boundary object. When the electronic device determines that there is a Figure 19 boundary object shown in the built area, the electronic device can generate detection frequency information to prompt the staff to regularly check its sealing performance.

[0249] Through the method provided in this embodiment, for the boundary objects of the purifier component type, since the electronic device can determine the leakage level corresponding to the boundary object according to the second positional relationship between the purification unit and the purification fan, the third positional relationship between the purification unit and the inhabitable space, and the fourth positional relationship between the purification fan and the inhabitable space, the method provided in this embodiment can improve the determination accuracy of the leakage level by the electronic device.

[0250] S10314. If the device type of the boundary object is a compressed air supply device type, identify the leakage level corresponding to the boundary object as a low-risk level.

[0251] In this embodiment, for the boundary object of the compressed air supply device type, since the pipeline part of this boundary object is in a positive pressure state, the electronic device can identify the leakage level corresponding to the boundary object of the compressed air supply device type as a low-risk level.

[0252] It should be noted that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution. The execution order of each process should be determined according to its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of this application.

[0253] Refer to Figure 23 , which shows a schematic diagram of a leakage judgment device for the pressure boundary of an inhabitable space provided by an embodiment of this application. Specifically, it may include a space recognition module 2301, a boundary object recognition module 2302, a level determination module 2303, and an information generation module 2304, where:

[0254] The space recognition module 2301 is used to determine at least one inhabitable space in the area to be recognized based on the space identifiers corresponding to each space to be recognized in the area to be recognized;

[0255] The boundary object recognition module 2302 is used to determine the boundary object corresponding to the inhabitable space from all target objects according to the object type of each target object in the area to be recognized and the relative positional relationship between the target object and the inhabitable space;

[0256] The level determination module 2303 is used to obtain the index data corresponding to the leakage judgment condition through the leakage judgment condition corresponding to the boundary object, and determine the leakage level corresponding to the boundary object according to the index data and the leakage judgment condition;

[0257] The information generation module 2304 is used to generate leakage prompt information based on the leakage levels corresponding to each boundary object.

[0258] The level determination module can also be used to, if the object type of the boundary object is of the ventilation system type, determine the leakage judgment condition and index data corresponding to the boundary object based on the equipment type to which the boundary object belongs in the ventilation system, and determine the leakage level corresponding to the boundary object according to the index data and the leakage judgment condition; if the object type of the boundary object is of the pipeline type, determine the leakage level corresponding to the boundary object based on the pressure difference between the medium pressure value inside the boundary object and the environmental pressure value of the environment where the boundary object is located; if the object type of the boundary object is of the geotechnical type, query the preset level mapping relationship based on the object identifier of the boundary object to determine the leakage level corresponding to the boundary object.
