[0045] 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.

[0046] This paper proposes a subway room location design method based on a mechanical simulation system. Figure 1This is a flow chart of a method for designing subway room locations based on a mechanical simulation system provided by an embodiment of the present invention. Figure 1 , specifically including:

[0047] S1. Obtain the connection relationship between the rooms in the subway station, and determine the topological relationship between the rooms in the subway station based on the connection relationship.

[0048] S11. Determine the preliminary connection relationship between the rooms in the subway station based on expert experience.

[0049] S12. Complete the preliminary connection relationship according to the subway station design specifications and the known subway station design drawings to obtain the completed connection relationship between the subway station rooms.

[0050] S13. Obtain the connection relationship between the rooms in the subway station according to the preliminary connection relationship and the completed connection relationship.

[0051] The connection relationships include adjacent, non-adjacent, and unknown.

[0052] Specifically, preliminary connection relationships between subway station rooms are determined based on expert experience, and the preliminary connection relationships determined by expert experience are used as the basis. For connection relationships not determined by the experts, the preliminary connection relationships are supplemented based on subway station design specifications and known subway station design drawings to determine the connection relationships between subway station rooms. When the connection relationships in the subway station design specifications and known subway station design drawings conflict with the connection relationships determined by expert experience, the connection relationships determined by expert experience are used as the basis. For connection relationships not determined by expert experience or subway station design specifications, since the connection relationships between subway station rooms of type x and type y may differ in different drawings in known subway design drawings, the situations in which the connection relationships between subway station rooms cannot be determined are defined as unknown connection relationships.

[0053] S14. Use the adjacency matrix L to represent the topological relationship between the rooms in the subway station.

[0054] Specifically, Figure 2 This is a schematic diagram of the topological relationship between rooms in a subway station provided by an embodiment of the present invention. Figure 3 is a schematic diagram of an adjacency matrix provided by an embodiment of the present invention, see Figure 2 and Figure 3 :

[0055] Adjacency matrix L={n xy}, where x represents a subway station room of type x, y represents a subway station room of type y, and n xy Indicates the connection relationship between subway station rooms of type x and subway station rooms of type y.

[0056] S141. If, according to the connection relationship, the connection relationship between the subway station room of type x and the subway station room of type y is adjacent, and the topological relationship between the subway station room of type x and the subway station room of type y is adjacent, then n xy =1;

[0057] S142. If, according to the connection relationship, the connection relationship between the subway station room of type x and the subway station room of type y is non-adjacent, then the topological relationship between the subway station room of type x and the subway station room of type y is non-adjacent, then n xy =0;

[0058] S143. If the connection relationship between the room at the subway station of type x and the room at the subway station of type y is unknown, then calculate and determine n by sampling from the probability distribution of the connection relationship between the room at the subway station of type x and the room at the subway station of type y. xy The value of .

[0059] Specifically, n is determined by sampling and calculating the probability distribution of the connection relationship between the subway station room of type x and the subway station room of type y. xy The probability distribution is expressed as N(μ,σ), μ represents the expected value, which can be given by expert experience or obtained from drawings, σ represents the standard deviation, and n xy Any number between 0 and 1.

[0060] S2. Determine the proxy points of each subway station room, set the constraints of each proxy point based on the topological relationship, and build a mechanical simulation system.

[0061] S21. Determine the proxy point of each subway station room and the area of ​​each subway station room, and use the proxy point as the center of the circle to represent the subway station room with circles of different radii according to the area.

[0062] Among them, the proxy point of the room is the center point of each subway station room, and the area of ​​each subway station room can be determined according to the design specifications.

[0063] S22. Set the spring force between the proxy points according to the topological relationship.

[0064] Specifically, Figure 4 is a schematic diagram of a spring force constraint between proxy points provided by an embodiment of the present invention, see Figure 4 For two adjacent subway station rooms, they are subject to the spring force exerted by each other. For two non-adjacent subway station rooms, there is no spring force between them. The closer the distance between the two adjacent subway station rooms is, the stronger the spring force exerted on each other is. For example, for the i-th proxy point S i , which is related to the proxy point S jand agent point S k are adjacent, then for the proxy point S i , which is affected by the agent point S j Applied spring force F ij and agent point S k Applied spring force F ik The resultant force F 合 , for the proxy point S k , which is only related to the proxy point S i Adjacent, then for the proxy point S k , which is only affected by the proxy point S i Applied spring force F ki .

[0065] S23. Setting a collision force between each proxy point and the boundary of the subway station so that each proxy point moves within the boundary of the subway station.

[0066] The subway station boundary is the boundary of the area where the subway station room layout needs to be designed.

[0067] S24. Setting the collision force between the proxy points so that the circles to which the proxy points belong do not overlap.

[0068] Specifically, Figure 5 is a schematic diagram of a collision force constraint between proxy points provided by an embodiment of the present invention, see Figure 5 , using circles to represent the area of ​​each subway station room. Since the areas of each subway station room cannot overlap, it is necessary to make the proxy point S i The circle and the proxy point S j The circles they belong to cannot overlap, so the collision force needs to be set so that the proxy point S i The circle and the proxy point S j When the circle they belong to comes into contact, a collision force is generated, which moves the proxy point S i The circle and the proxy point S j The circle to which it belongs bounces off, thus avoiding the proxy point S i The circle and the proxy point S j The circles overlap.

[0069] Furthermore, before constructing the mechanical simulation system, the process also includes setting parameters of each proxy point and system parameters.

[0070] Among them, the parameters of each proxy point include mass, initial velocity, initial position, movement direction, etc., and the system parameters include system initial energy and system damping, etc.

[0071] For example, the mass of each proxy point can be set to 1, the initial velocity of each proxy point is determined by looking up a table based on different room types, and the initial position and movement direction of each proxy point can be set according to actual conditions. The initial energy of the system can be calculated based on the mass and initial velocity of each proxy point using the following formula:

[0072] ;

[0073] Where E represents the initial energy of the system, i represents the i-th agent point, l represents the total number of agent points, m i represents the quality of the i-th proxy point, v i represents the initial velocity of the i-th proxy point. The system damping can be set according to the actual situation. For example, it can be set to 0.2. The system damping affects the convergence speed of the mechanical simulation system. The larger the system damping, the faster the convergence speed of the mechanical simulation system.

[0074] S3. Run the mechanical simulation system to obtain the final position coordinates of each proxy point.

[0075] Specifically, Figure 6 is a schematic diagram of the movement of each proxy point in a mechanical simulation system provided by an embodiment of the present invention. Figure 7 This is a heat map of the final position coordinates of each proxy point provided by an embodiment of the present invention, see Figure 6 and Figure 7 , run the mechanical simulation system, obtain the final position coordinates of each proxy point, and import the final position coordinates of each proxy point into Excel for storage.

[0076] Furthermore, each time the above method is executed once, a set of layout solutions can be obtained. By repeatedly executing the above steps, multiple sets of layout solutions can be obtained. Based on the multiple sets of layout solutions, unreasonable solutions can be eliminated and the optimal solution can be screened out.

[0077] The present invention determines the connection relationships between subway station rooms and constructs a mechanical simulation system based on these connections. The final position coordinates of each proxy point are obtained through the mechanical simulation system, which can automatically and quickly generate multiple layout plans, thereby quickly finding the optimal solution and significantly shortening the design cycle. Furthermore, the data output by the mechanical simulation system can be stored, providing important reference information for subsequent maintenance and renovation work.

[0078] In addition, when project requirements change, the subway room location design method based on the mechanical simulation system can quickly recalculate and provide new layout plans, making it easier to modify the room location layout and improving the adaptability of the design plan.
