[0002] As an important part of urban public transportation, the underground rail transit station has extremely significant characteristics of being enclosed and densely populated, which poses extremely high requirements for the environmental control room. The environmental control room is not only directly related to the comfort and health of passengers in the station, but also deeply affects the stable operation of various equipment in the station and the safety guarantee in case of emergencies. A well-designed environmental control room can accurately maintain the appropriate temperature, humidity and air quality in the station, provide a comfortable waiting environment for passengers, and at the same time ensure the normal operation of the station equipment and extend its service life.

[0003] However, in the design of the existing environmental control room of the underground rail transit station, there are the following problems: To ensure the efficient operation of the system and the flexibility of equipment layout, and to ensure that there is enough space for equipment layout, designers usually reserve enough space for area redundancy design. However, this approach inevitably increases the construction area of the station, thereby driving up the construction cost. This not only poses a challenge to the economic feasibility of the rail transit project, but also may waste precious urban underground resources due to improper space utilization.

Specific Embodiments

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope protected by the present invention.

[0022] When designing the environmental control rooms in the rail transit underground station, due to the space redundancy design, the construction cost of the rail transit underground station is increased. Therefore, this application provides a design method for the environmental control rooms in the rail transit underground station based on the equipment layout. Refer to Figure 1 , and the method specifically includes: S1: Obtain the site range of the environmental control rooms in the rail transit underground station; the site range is used to represent the outer contour of the environmental control rooms; it includes the location information, area, shape, height of the environmental control rooms, and the location information of obstacles, etc.

[0023] Among them, the obstacles refer to the objects that cannot be used for the layout of the environmental control rooms, such as beams, slabs, columns, walls, etc., which are spaces that cannot be used for the layout of environmental control rooms.

[0024] S2: Obtain the schematic diagram of the equipment of the environmental control system, and convert the association relationship between the equipment from the schematic diagram form to the bubble chart form, so as to prepare for determining the final positions and association relationships of the equipment through mechanical simulation later.

[0025] In some embodiments, in S2, the method of converting the association relationship between the equipment from the schematic diagram form to the bubble chart form is as follows: S21: According to the system annotation information in the schematic diagram, disassemble the schematic diagram of the equipment of the environmental control system into the schematic diagrams of the equipment of the subsystems; The system annotation information includes the subordination relationship of each subsystem to the system. The entire environmental control system includes four subsystems, namely the tunnel ventilation system, the exhaust system, the smoke exhaust system, and the fresh air system. According to this standard, the schematic diagram of the equipment of the environmental control system can be disassembled into the schematic diagrams of the equipment of the tunnel ventilation system, the exhaust system, the smoke exhaust system, and the fresh air system.

[0026] S22: Based on the equipment element information in the schematic diagram, disassemble the schematic diagrams of the equipment of the subsystems respectively to obtain the element information in each subsystem; the element information in the subsystem includes equipment, ventilation paths, and the ventilation areas corresponding to the ventilation paths; the ventilation area corresponding to the ventilation path refers to the minimum area of the cross-section of the ventilation path.

[0027] The equipment element information in the schematic diagram includes: equipment such as fans, air ducts, air valves, mufflers, etc. and the equipment areas; ventilation paths, the ventilation areas corresponding to the ventilation paths, etc. information, as well as the subordination information of each element information to the subsystem. Based on this, disassemble the schematic diagrams of the equipment of the subsystems to obtain the element information in each subsystem.

[0028] S23: According to the element information in each subsystem, create the topological relationship diagrams in the form of bubble charts for each subsystem respectively, and complete the conversion of the association relationship between the equipment from the schematic diagram form to the bubble chart form.

[0029] A bubble chart can be understood as a data visualization tool, a variant of a scatter plot, which can display the relationships between multiple variables and the distribution of data points at the same time.

[0030] In some embodiments, when creating the topological relationship diagrams in the form of bubble charts for each subsystem according to the element information in each subsystem, the position of the equipment proxy point is represented by the center of the bubble, and the bubble area is equal to the area of the floor plan of each equipment (the product of the length and width of the equipment is equal to the area of the circular bubble); the ventilation path is represented by the bubble connection line, and the ventilation area is marked as the attribute of the corresponding bubble connection line.

[0031] Exemplarily, taking the "combined air handling unit" as an example, its representation form of the position and connection relationship in the schematic diagram is as Figure 2 shown, and its representation form of the position and association relationship in the form of a bubble diagram is as Figure 3 shown.

[0032] S3: According to the association relationship between devices in the form of a bubble diagram, within the site scope, by means of mechanical simulation, determine the final association relationship between devices; from the final association relationship between devices, the final positions of each bubble, the connection relationship between bubbles, etc. can be determined.

[0033] S31: Construct a mechanical simulation system, which takes the initial positions of device proxy points, the areas of devices, ventilation paths, and the ventilation areas corresponding to the ventilation paths as inputs, and takes the final positions of device proxy points as outputs; By using device proxy points to represent the centers of bubbles, construct constraints between device proxy points such as elastic forces and collision forces according to the association relationship between devices in the form of a bubble diagram, add the initial velocities of device proxy points and system damping, model the corresponding mechanical simulation system, use the head and tail devices of each subsystem as fixed bubbles, and let other bubbles in the system collide to determine the final positions.

[0034] The parameters input into the mechanical simulation system include the initial positions of device proxy points, mass attributes, topological relationship parameters, initial velocity vectors, and system damping coefficients.

[0035] Initial positions of device proxy points: Clearly define their spatial positions in the environmental control room with three-dimensional coordinates. For example, the coordinates of device proxy point A are (x1, y1, z1), and determine the head and tail devices of each subsystem from the association relationship between devices as fixed bubbles, and obtain the positions of the corresponding bubbles.

[0036] Mass attributes: Reflect the device mass by the device area, with the unit of kilograms.

[0037] Topological relationship parameters: The topological relationship parameters include the connection method (i.e., the ventilation path) and the strength coefficient (i.e., the ventilation area corresponding to the ventilation path). Among them, the connection method reflects the connectivity between device proxy points, and the strength coefficient characterizes the tightness of the connection between devices. This coefficient is closely related to the ventilation area. Specifically, the larger the ventilation area, the larger the strength coefficient, indicating that the connection between devices is closer; conversely, the smaller the ventilation area, the smaller the strength coefficient, meaning that the connection between devices is looser.

[0038] Initial velocity vector: Set the initial velocity magnitude and direction of the device proxy point, which determines the initial motion state of the simulation. The initial velocity vector is usually set by the user according to the specific simulation scenario and the expected motion state. When constructing a mechanical simulation system, the user inputs the initial velocity magnitude and direction of the device proxy point based on the prior knowledge of the environmental control room and the simulation purpose. The magnitude and direction of the initial velocity depend on the pulling conditions of the fixed bubble positions of the first and last devices in each subsystem determined based on different schemes.

[0039] System damping coefficient: Reflects the comprehensive factors that impede the motion of the device proxy point, making the simulation more realistic. During the operation of a similar environmental control room or other related systems, estimate the system damping coefficient based on the velocity decay of the moving devices. Exemplarily, an object can be allowed to perform free vibration under an initial perturbation, and the system damping coefficient can be determined by measuring the decay of the vibration.

[0040] The parameter output by the mechanical simulation system is the final position of the device proxy point. As time changes, the position coordinates of the device proxy point change, showing the new positions of each device proxy point after each time step, forming a motion trajectory, and determining the final position of the device proxy point at the end of the collision.

[0041] S32: Obtain the initial positions, device areas, ventilation paths, and ventilation areas corresponding to the ventilation paths of the device proxy points in each subsystem, and input them into the constructed mechanical simulation system for collision to obtain the final positions of the device proxy points in each subsystem, thereby determining the final association relationship between the devices.

[0042] Initialization of the device proxy point: According to the input initial positions of the device proxy points, accurately place the device proxy points in the three-dimensional space of the environmental control room. The positions of these proxy points serve as the basis for subsequent mechanical simulations, and their coordinates are determined based on the device proxy point position input items.

[0043] Construct force constraints: Simulate the elastic force and collision force constraints between devices according to the connection method and strength coefficient in the topological relationship parameters. For the elastic force, when the position of the device proxy point changes, calculate the elastic force according to Hooke's law F = k×△x, making the relevant devices tend to approach each other. The changes in position and force are presented through the output items of "position coordinates changing with time" and "force condition", where F represents the elastic force, k represents the strength system, and △x represents the change in position. For the collision force, when the distance between device proxy points approaches or reaches the set threshold, calculate and apply the collision force based on the collision setting and mass attribute in the topological relationship. This force will change the motion state of the device proxy point and is reflected through the output items of "velocity and acceleration" and "force condition".

[0044] Initial velocity assignment: Set the initial velocity for the device proxy point according to the initial velocity vector input item, which determines the motion state at the start of the simulation. Calculate the initial kinetic energy according to the kinetic energy formula Ek = 1 / 2mv². This energy is part of the initial energy of the system. The position change caused by the initial velocity is recorded in the "Position coordinates changing with time", where Ek represents kinetic energy, m represents the mass attribute, indicated by the device area, and v represents the velocity of the device proxy point.

[0045] Apply system damping: According to the system damping coefficient, considering comprehensive factors such as air resistance and mechanical friction, calculate the damping force using F_d = b×v, where F_d represents the resistance force, b is the damping coefficient, and v represents the velocity of the device proxy point. This force will cause a change in the velocity of the device proxy point, and this change is reflected in the "Velocity and acceleration" output item. The situation of the conversion of the system's mechanical energy into heat energy is reflected in the "System energy change" output item.

[0046] Determine device positioning: As the mechanical simulation system runs, after the collision is completed and the system energy is stable (affected by damping), take the midpoint of each bubble (device proxy point) as the final position of the device proxy point to complete the device positioning. During the simulation process, provide system information to the user through multiple parameters ("Position coordinates changing with time", "Velocity and acceleration", "Force situation", and "System energy change") to assist in optimizing the device layout.

[0047] When running the mechanical simulation system, the above steps will be integrated, using the input parameters, and based on the corresponding physical laws, to ensure that the system converges within the environmental control room site, achieve accurate device positioning, optimize the device layout and performance of the environmental control room in the rail transit underground station, improve the design accuracy, optimize the layout of the environmental control room in the rail transit underground station, and further reduce the construction economic cost.

[0048] In some embodiments, in S4, based on the final association relationship between devices, divide the partition walls to complete the design of the environmental control room in the rail transit underground station, including the following steps: S41: Based on the final association relationship between devices, divide each subsystem to determine the position of the subsystem partition wall; S42: According to the positions of the bubbles with parallel air flow channels, determine the positions of each branch partition wall in each subsystem; S43: According to the positions of the interactive air flow channels of each subsystem, determine the interactive partition walls of each subsystem; S44: Determine the devices that need to be separated by partition walls and determine the positions of the device partition walls; S45: According to the positions of the subsystem partition walls, the positions of the branch partition walls, the interactive partition walls of the subsystems, and the positions of the device partition walls, complete the design of the environmental control room in the rail transit underground station.

[0049] In some embodiments, in S41, according to the final association relationship between devices, each subsystem is partitioned to determine the position of the subsystem partition wall, specifically as follows: S411: Obtain the positions of the bubbles at the head and tail ends of each subsystem from the final association relationship between devices; S412: Based on the positions of the bubbles at the head and tail ends of each subsystem, connect the bubbles at each end of the subsystem to the corresponding bubbles at the adjacent ends of the adjacent subsystems to obtain the inter-system connection lines, and determine the midpoints of each inter-system connection line; S413: Connect the midpoints of the inter-system connection lines of adjacent subsystems in sequence to form the initial center line of the subsystem partition wall.

[0050] S414: Determine the center line of the subsystem partition wall by judging whether the initial center line of the subsystem partition wall intersects with the bubbles. The judgment method is as follows: If there is no intersection, use the initial center line of the subsystem partition wall as the center line of the subsystem partition wall; If there is an intersection, determine the crossed bubble and the adjacent bubble in the adjacent subsystem; Connect the crossed bubble and the adjacent bubble, and determine the midpoint of this connection line as the inflection point of the center line of the subsystem partition wall; Connect the midpoints of the inter-system connection lines at the head ends of adjacent subsystems, the inflection points of the center line, and the midpoints of the inter-system connection lines at the tail ends in sequence as the center line of the subsystem partition wall; S415: Determine the position of the subsystem partition wall based on the center line of the subsystem partition wall.

[0051] Exemplarily, as Figure 4 the subsystem partition wall shown in separates each subsystem.

[0052] In some embodiments, S42: Determine the positions of the branch partition walls in each subsystem according to the positions of the bubbles with parallel air flow channels, including the following sub-steps: S421: Obtain the positions of the bubbles with parallel air flow channels between the branches in each subsystem from the final association relationship between devices; the bubbles with parallel air flow channels are the bubbles with a connection relationship between the branches; S422: Connect the bubbles with parallel air flow channels of adjacent branches in the same subsystem to obtain the inter-branch connection lines, and determine the midpoints of each inter-branch connection line; S423: Connect the midpoints of the inter-branch connection lines of adjacent branches in the same subsystem in sequence to form the center line of the branch partition wall; S424: Determine the positions of the branch partition walls in each subsystem based on the center line of the branch partition wall.

[0053] Exemplarily, as Figure 4The subsystem branch partition walls shown in the figure divide the branches in the same subsystem.

[0054] In some embodiments, S43: Determine the interactive partition walls of each subsystem according to the positions of the interactive air flow channels of each subsystem; S431: Obtain the positions of the interactive air flow channels of each subsystem from the final associated relationship between devices; for the final associated relationship between devices, the position where each subsystem is connected is the position of the interactive air flow channel.

[0055] S432: Obtain the minimum volume required for the interactive air flow channel from the device schematic diagram of the environmental control system; S433: Determine the interactive partition walls of each subsystem based on the positions of the interactive air flow channels of each subsystem and the minimum volume required for the interactive air flow channel.

[0056] Exemplarily, as Figure 4 The interactive partition walls of the subsystems shown in the figure establish interactive channels between each subsystem.

[0057] In some embodiments, S44: Determine the devices that need to be separated by partition walls and determine the positions of the device partition walls, specifically: S441: Determine the devices that need to be separated by partition walls through the device installation information; S442: Determine the bubble positions corresponding to the devices that need to be separated by partition walls in the final associated relationship between devices; S443: Select the partition wall closest to the bubble corresponding to the device that needs to be separated by partition walls among the partition walls of each subsystem and the branch partition walls; set a connection line in the vertical direction of the closest partition wall and tangent to the bubble corresponding to the device that needs to be separated by partition walls as the center line of the fixed device partition wall; S444: Determine the positions of the device partition walls based on the center line of the fixed device partition wall.

[0058] Exemplarily, as Figure 4 The device partition walls shown in the figure isolate the devices.

[0059] This application first converts the associated relationship of the devices in the environmental control system from the schematic diagram form to the bubble diagram form, then determines the final associated relationship between devices through the method of mechanical simulation, and then determines the positions of various partition walls according to the final associated relationship between devices to complete the design of the environmental control room. It overcomes the redundant design problem caused by first selecting the space and then arranging the devices in the traditional design, and reduces the construction economic cost of the underground vehicle in rail transit.

[0060] In some embodiments, after S4, it further includes S5: Verify the ventilation area of each channel formed by the partition walls.

[0061] Exemplarily, after the partition walls are determined, multiple channels are formed, and it is verified whether the cross-sectional areas of the channels meet the preset requirements.

[0062] Traditional designs for subway environmental control rooms usually adopt a relatively extensive layout method, that is, directly setting air ducts under the existing civil engineering conditions and then arranging equipment inside the air ducts. This design method often does not actively optimize the equipment layout. Even if there is spare space in a single air duct, little consideration is given to further compressing the channel size. This design concept directly leads to an increase in the civil engineering area and thus raises the overall project cost.

[0063] In contrast, the innovative design method proposed in this application first separates the equipment system from the air ducts. By precisely analyzing the functional associations and mechanical interference relationships between equipment rooms, all equipment is optimally arranged in the smallest achievable space. On this basis, the air duct system is then divided and designed, thereby maximizing the space utilization rate and effectively avoiding waste of project cost.

[0064] Taking the fresh air and exhaust air systems of a certain station as an example, Figure 5 is a schematic diagram of the building area of the second basement floor using the traditional design method provided by the embodiment of the present invention, Figure 6 is a schematic diagram of the building area of the first basement floor using the traditional design method provided by the embodiment of the present invention. The building area required by the traditional design method is approximately 574 + 918 = 1492 square meters. Figure 7 is a schematic diagram of the building area of the second basement floor using the design method of this application provided by the embodiment of the present invention; Figure 8 is a schematic diagram of the building area of the first basement floor using the design method of this application provided by the embodiment of the present invention. The building area required by using the design method of this application can be reduced to 210 + 166 + 788 = 1164 square meters, and the project cost can be reduced by approximately 22%.

[0065] It can be seen from this that the design method for environmental control rooms in rail transit underground stations based on equipment layout provided by the present invention significantly improves the space utilization efficiency and greatly reduces the project cost.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of the present invention.
