Description

Technical Field

[0001] The present invention relates to the field of rail transit technology, and in particular to a design method for an environmental control room in an underground rail transit station based on equipment layout. Background Art

[0002] As a vital component of urban public transportation, underground rail transit stations are characterized by their enclosed and densely populated environment, placing extremely high demands on environmental control rooms. These rooms not only directly impact the comfort and health of passengers within the station but also profoundly influence the stable operation of various equipment within the station and its safety in emergency situations. A well-designed environmental control room can precisely maintain optimal temperature, humidity, and air quality within the station, providing a comfortable waiting environment for passengers while ensuring the proper operation and extended service life of station equipment.

[0003] However, the design of environmental control rooms in existing underground rail transit stations presents the following challenges: To ensure efficient system operation and flexible equipment layout, designers often reserve sufficient space for equipment layout. This inevitably increases the station's floor area, driving up construction costs. This not only poses a challenge to the economic viability of rail transit projects but also risks wasting precious urban underground resources due to improper space utilization.

[0004] Therefore, there is an urgent need for a design method for environmental control rooms in underground rail transit stations based on equipment layout to improve design accuracy, optimize the layout of environmental control rooms in underground rail transit stations, and reduce economic costs.

[0061] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention are described clearly and completely below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0062] In the existing design of the environmental control room of the underground railway station, the construction economic cost of the underground railway station is improved due to the space redundancy design. Therefore, this application provides a design method of the environmental control room of the underground railway station based on the equipment layout. Figure 1 , the method specifically includes:

[0063] S1: Obtain the site scope of the environmental control room of the underground rail transit station; the site scope is used to represent the outer contour of the environmental control room; including the location information, area, shape, height and location information of obstacles of the environmental control room.

[0064] Among them, obstacles are objects that cannot be used to arrange the environmental control room, such as beams, plates, columns, walls, and other spaces that are not suitable for arranging the environmental control room.

[0065] S2: Obtain the equipment schematic diagram of the environmental control system and convert the relationship between the equipment from the schematic diagram form to the bubble diagram form, in preparation for the subsequent determination of the final position and relationship of the equipment through mechanical simulation.

[0066] In some embodiments, in S2, the method for converting the association relationship between devices from a schematic diagram to a bubble diagram is:

[0067] S21: Based on the system annotation information in the schematic diagram, the equipment schematic diagram of the environmental control system is disassembled into equipment schematic diagrams of the subsystems;

[0068] The system annotation information includes the affiliation of each subsystem to the system. The entire environmental control system consists of four subsystems, namely the tunnel ventilation system, the exhaust system, the smoke exhaust system and the fresh air system. Based on this standard, the equipment principle of the environmental control system can be disassembled into the tunnel ventilation system equipment schematic diagram, the exhaust system equipment schematic diagram, the smoke exhaust system equipment schematic diagram and the fresh air system equipment schematic diagram.

[0069] S22: Using the device element information in the schematic diagram, the device schematic diagram of the subsystem is disassembled respectively to obtain the element information in each subsystem; the element information in the subsystem includes the equipment, the ventilation path and the ventilation area corresponding to the ventilation path; wherein the ventilation area corresponding to the ventilation path refers to the minimum area of ​​the cross section of the ventilation path.

[0070] The equipment element information in the schematic diagram includes: fans, air ducts, dampers, mufflers, and other equipment and their area; ventilation paths, corresponding ventilation areas, and other information; as well as the subsystem affiliation of each element information. Based on this, the subsystem equipment schematic diagram is disassembled to obtain the element information within each subsystem.

[0071] S23: Based on the element information in each subsystem, a topological relationship diagram in the form of a bubble diagram is created for each subsystem, and the relationship between the devices is converted from the schematic diagram form to the bubble diagram form.

[0072] A bubble chart can be understood as a data visualization tool, a variant of a scatter plot, which can simultaneously display the relationship between multiple variables and the distribution of data points.

[0073] In some embodiments, when creating a topological relationship diagram in the form of a bubble diagram for each subsystem based on the element information in each subsystem, the center of the bubble represents the location of the device proxy point, and the bubble area is equal to the area of ​​the plan view of each device (the product of the length and width of the device is equal to the area of ​​the circular bubble); the bubble connecting line represents the ventilation path, and the ventilation area is marked as the attribute of the corresponding bubble connecting line.

[0074] For example, taking the “combined air conditioning unit” as an example, its position and connection relationship are represented in the schematic diagram as follows: Figure 2 As shown, the representation of their positions and association relationships in the bubble chart is as follows Figure 3 shown.

[0075] S3: Based on the relationship between devices in the form of a bubble diagram, the final relationship between devices is determined within the site through mechanical simulation. The final position of each bubble, the connection relationship between bubbles, etc. can be determined based on the final relationship between devices.

[0076] S31: constructing a mechanical simulation system, which takes the initial position of the device proxy point, the device area, the ventilation path, and the ventilation area corresponding to the ventilation path as input, and takes the final position of the device proxy point as output;

[0077] By using device proxy points to represent the bubble center, constraints between device proxy points such as elastic force and collision force are constructed according to the association relationship between devices in the form of a bubble diagram. The initial velocity of the device proxy points and the system damping are added to model the corresponding mechanical simulation system. The first and last devices of each subsystem are used as fixed bubbles, and other bubbles in the system collide to determine the final position.

[0078] The input parameters of the mechanical simulation system include the initial position of the device proxy point, mass properties, topological relationship parameters, initial velocity vector and system damping coefficient.

[0079] Initial position of the device proxy point: Use three-dimensional coordinates to determine its spatial position in the environmental control room, such as the coordinates of device proxy point A (x1, y1, z1). From the relationship between devices, determine the head-end and tail-end devices of each subsystem as fixed bubbles and obtain the position of the corresponding bubbles.

[0080] Mass attribute: The mass of the equipment is expressed as the area of ​​the equipment, and the unit is kilogram.

[0081] Topology parameters: Topology parameters include the connection method (i.e., ventilation path) and the strength coefficient (i.e., the ventilation area corresponding to the ventilation path). The connection method reflects the connectivity between device proxy points, while the strength coefficient characterizes the tightness of the connection between devices and is closely related to the ventilation area. Specifically, a larger ventilation area indicates a larger strength coefficient, indicating a tighter connection between devices. Conversely, a smaller ventilation area indicates a smaller strength coefficient, indicating a looser connection between devices.

[0082] Initial Velocity Vector: This sets the initial velocity magnitude and direction of the device proxy, determining the starting motion state of the simulation. The initial velocity vector is typically set by the user based on the specific simulation scenario and the desired motion state. When building a mechanical simulation system, the user enters the initial velocity magnitude and direction of the device proxy based on prior knowledge of the environmental control room and the simulation objectives. The magnitude and direction of the initial velocity are determined by the pull conditions of the fixed bubble positions of the first and last devices in each subsystem, as determined by different schemes.

[0083] System Damping Coefficient: This reflects the comprehensive factors that hinder the motion of a device's proxy point, making the simulation more realistic. The system damping coefficient is estimated based on the velocity decay of the moving device during the operation of a similar environmentally controlled room or other related system. For example, the system damping coefficient can be determined by allowing the object to vibrate freely under an initial disturbance and measuring the vibration decay.

[0084] The output parameter of the mechanical simulation system is the final position of the device proxy. The coordinates of the device proxy points change over time, displaying the new position of each device proxy point after each time step. This forms a motion trajectory and determines the final position of the device proxy point at the end of the collision.

[0085] S32: Obtain the initial position of the device proxy point in each subsystem, the device area, the ventilation path, and the ventilation area corresponding to the ventilation path, and input them into the constructed mechanical simulation system for collision to obtain the final position of the device proxy point in each subsystem, thereby determining the final association relationship between the devices.

[0086] Initialization of device proxy points: Based on the input device proxy initial positions, the device proxy points are accurately placed in the 3D 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.

[0087] Construct force constraints: Based on the connection method and strength coefficient in the topological relationship parameters, simulate the elastic force and collision force constraints between devices. For elastic force, when the position of the device proxy point changes, the elastic force is calculated according to Hooke's law F=k×△x, so that the related devices tend to move closer together. The changes in position and force are presented through the "Position coordinates changing over time" and "Force conditions" output items, where F represents the elastic force, k represents the strength system, and △x represents the change in position. For collision force, when the distance between device proxy points approaches or reaches the set threshold, the collision force is calculated and applied based on the collision settings and mass properties in the topological relationship. This force will change the motion state of the device proxy point, which is reflected through the "Velocity and Acceleration" and "Force conditions" output items.

[0088] Assign Initial Velocity: Use the Initial Velocity Vector input to set the initial velocity for the device proxy, which determines the motion state at the start of the simulation. The initial kinetic energy is calculated using the kinetic energy formula Ek = 1 / 2mv². This energy is part of the system's initial energy. The position change caused by the initial velocity is recorded in the "Position Coordinates Over Time" column, where Ek represents kinetic energy, m represents mass (illustrated by the device area), and v represents the velocity of the device proxy.

[0089] Applying system damping: Based on the system damping coefficient, taking into account factors such as air resistance and mechanical friction, the damping force is calculated using the formula F_d = b × v, where F_d represents the resistance, b is the damping coefficient, and v represents the velocity of the device proxy. This force changes the velocity of the device proxy, which is reflected in the "Velocity and Acceleration" output. The conversion of the system's mechanical energy into heat is reflected in the "System Energy Change" output.

[0090] Determine device positioning: As the mechanical simulation system runs, after the collision is complete and the system energy stabilizes (due to damping), the midpoint of each bubble (device proxy point) is used as the final device proxy position, completing device positioning. During the simulation, multiple parameters ("position coordinates over time," "velocity and acceleration," "force conditions," and "system energy changes") are used to provide users with system information to assist in optimizing device layout.

[0091] When running the mechanical simulation system, the above steps will be integrated, and the input parameters will be used according to the corresponding physical laws to ensure that the system converges within the environmental control room site and achieve precise equipment positioning. This will optimize the equipment layout and performance of the environmental control room of the underground rail transit station, improve design accuracy, optimize the layout of the environmental control room of the underground rail transit station, and further reduce the economic cost of construction.

[0092] In some embodiments, in S4, based on the final association relationship between the devices, partition walls are divided to complete the design of the environmental control room of the underground rail transit station, including the following steps:

[0093] S41: Based on the final relationship between the devices, each subsystem is divided and the location of the subsystem partition wall is determined;

[0094] S42: Determine the position of each branch partition wall in each subsystem according to the position of the bubbles in the parallel airflow channel;

[0095] S43: Determine the interactive partition walls of each subsystem according to the positions of the interactive airflow channels of each subsystem;

[0096] S44: Determine whether a partition wall is required to separate the equipment and determine the location of the equipment partition wall;

[0097] S45: Complete the design of the environmental control room of the underground rail transit station based on the location of the subsystem partition walls, branch partition walls, subsystem interaction partition walls and equipment partition walls.

[0098] In some embodiments, in S41, each subsystem is divided according to the final association relationship between the devices, and the position of the subsystem partition wall is determined, specifically:

[0099] S411: Obtain the position of the bubbles at the head and tail ends of each subsystem from the final association relationship between the devices;

[0100] S412: Based on the positions of the bubbles at the head and tail ends of each subsystem, the bubbles at each end of the subsystem are connected to the bubbles at the corresponding ends of the adjacent subsystems to obtain connecting lines between the systems, and the midpoints of the connecting lines between the systems are determined;

[0101] 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.

[0102] S414: Determine the center line of the subsystem partition wall by judging whether the initial center line of the subsystem partition wall intersects the bubble. The judgment method is:

[0103] If there is no intersection, the initial center line of the subsystem partition wall shall be used as the center line of the subsystem partition wall;

[0104] If there is intersection, determine the adjacent bubbles in the crossed bubble and the adjacent subsystem;

[0105] Connect the crossed bubble and the adjacent bubble, and determine the midpoint of the connecting line as the centerline inflection point of the subsystem partition wall;

[0106] Connect the midpoints of the connecting lines between the head and tail ends of adjacent subsystems, the inflection points of the center lines, and the midpoints of the connecting lines between the tail ends to serve as the center lines of the subsystem partition walls.

[0107] S415: Determine the position of the subsystem partition wall based on the center line of the subsystem partition wall.

[0108] For example, Figure 4 The subsystem partition walls shown in the figure separate the subsystems.

[0109] In some embodiments, S42: determining the position of each branch partition wall in each subsystem according to the position of the bubbles in the parallel airflow channel includes the following sub-steps:

[0110] S421: Obtaining, from the final association relationship between the devices, the locations of bubbles having parallel airflow channels between the branches in each subsystem; the bubbles having parallel airflow channels are bubbles having a connection relationship between the branches;

[0111] S422: connecting bubbles with parallel airflow channels in adjacent branches of the same subsystem to obtain connecting lines between branches, and determining the midpoint of each connecting line between branches;

[0112] S423: Connect the midpoints of the connecting lines between adjacent branches of the same subsystem in sequence to form the center line of the branch partition wall;

[0113] S424: Determine the position of each branch partition wall in each subsystem using the center line of the branch partition wall.

[0114] For example, Figure 4 The subsystem branch partition wall shown in the figure separates the branches in the same subsystem.

[0115] In some embodiments, S43: determining the interactive partition walls of each subsystem according to the positions of the interactive airflow channels of each subsystem;

[0116] S431: Obtain the location of the interactive airflow channel of each subsystem from the final association relationship between the devices; the location where each subsystem is connected in the final association relationship between the devices is the location of the interactive airflow channel.

[0117] S432: Obtain the minimum volume required for the interactive airflow channel from the equipment schematic diagram of the environmental control system;

[0118] S433: Determine the interactive partition walls of each subsystem based on the positions of the interactive airflow channels of each subsystem and the minimum volumes required for the interactive airflow channels.

[0119] For example, Figure 4 The subsystem interaction walls shown in the figure establish interaction channels between the subsystems.

[0120] In some embodiments, S44: determining that a partition wall is required to separate the equipment and determining the location of the equipment partition wall is specifically as follows:

[0121] S441: Determine through equipment installation information that a partition wall is required to separate the equipment;

[0122] S442: In the final association relationship between the devices, determine the bubble position corresponding to the device that needs to be separated by a partition wall;

[0123] S443: Among the subsystem partitions and branch partitions, select the partition closest to the bubble corresponding to the equipment to be separated by the partition wall; set a connecting line in the vertical direction of the closest partition wall, tangent to the bubble corresponding to the equipment to be separated by the partition wall, and use it as the center line of the fixed equipment partition wall;

[0124] S444: Determine the position of the equipment partition wall by fixing the center line of the equipment partition wall.

[0125] For example, Figure 4 The equipment partition wall shown in the figure is used to isolate the equipment.

[0126] This application first converts the equipment relationships of the environmental control system from a schematic diagram to a bubble diagram. Then, through mechanical simulation, the final equipment relationships are determined. Based on these final equipment relationships, the positions of various partition walls are determined to complete the environmental control room design. This overcomes the redundant design issues caused by traditional design methods, which first select the space and then arrange the equipment, and reduces the economic cost of underground rail transit construction.

[0127] In some embodiments, after S4, the step further includes S5: verifying the ventilation area of ​​each channel formed by the partition wall.

[0128] For example, after the partition wall is determined, multiple channels will be formed to verify whether the cross-sectional area of ​​each channel meets the preset requirements.

[0129] Traditional subway environmental control room designs typically employ a relatively extensive layout approach, directly constructing air ducts within existing civil engineering conditions and then placing equipment within them. This approach often fails to proactively optimize equipment layout. Even if excess space exists within a single duct, further reducing its size is rarely considered. This design approach directly increases the civil engineering area, which in turn drives up the overall project cost.

[0130] In contrast, the innovative design approach proposed in this application first separates the equipment system from the air duct. By precisely analyzing the functional relationships and mechanical interference between the equipment, all equipment is optimally arranged within the smallest achievable space. Based on this foundation, the duct system is then divided and designed, maximizing space utilization and effectively avoiding wasteful construction costs.

[0131] Take the fresh air and exhaust system of a station as an example. Figure 5 This is a schematic diagram of the building area of ​​the second underground floor using a traditional design method provided by an embodiment of the present invention. Figure 6 This is a schematic diagram of the building area of ​​the underground floor using the traditional design method provided by an embodiment of the present invention. The building area required by the traditional design method is approximately 574+918=1492 square meters. Figure 7 This is a schematic diagram of the area of ​​the underground second floor provided by an embodiment of the present invention using the design method of the present application; Figure 8 This is a schematic diagram of the building area of ​​the underground first floor provided by an embodiment of the present invention using the design method of the present application. The building area required by the design method of the present application can be reduced to 210+166+788=1164 square meters, and the project cost can be reduced by about 22%.

[0132] It can be seen that the design method of the environmental control room of the rail transit underground station based on equipment layout provided by the present invention significantly improves the space utilization efficiency and greatly reduces the project cost.

[0133] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the technical solutions of the embodiments of the present invention.
