DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0017] The present invention proposes a subway room location design method based on a mechanical simulation system. Figure 1 is a flow chart of a subway room location design method based on a mechanical simulation system provided by an embodiment of the present invention, see Figure 1 , specifically including: S1. Obtain the connection relationship between the rooms in the subway station, and determine the topological relationship between the rooms in the subway station according to the connection relationship.

[0018] S11. Determine the preliminary connection relationship between the rooms in the subway station based on expert experience.

[0019] S12. According to the subway station design specifications and the known subway station design drawings, the preliminary connection relationship is completed to obtain the completed connection relationship between the subway station rooms.

[0020] S13. Obtain the connection relationship between the rooms in the subway station according to the preliminary connection relationship and the completed connection relationship.

[0021] The connection relationships include adjacent, non-adjacent and unknown.

[0022] Specifically, the preliminary connection relationship between the rooms in the subway station is determined based on expert experience, and the preliminary connection relationship given by the expert experience shall prevail. For the connection relationship not given by the expert, the preliminary connection relationship is completed according to the subway station design specification and the known subway station design drawings to obtain the connection relationship between the rooms in the subway station. When there is a conflict between the connection relationship in the subway station design specification and the known subway station design drawings and the connection relationship given by expert experience, the connection relationship given by expert experience shall prevail. For the connection relationship not given by expert experience and subway station design specifications, since in the known subway design drawings, the connection relationship between the subway station room of type x and the subway station room of type y may be different in different drawings, therefore, the situation where the connection relationship between the subway station rooms cannot be determined is defined as an unknown connection relationship.

[0023] S14. Use the adjacency matrix L to represent the topological relationship between the rooms in the subway station.

[0024] Specifically, Figure 2 is a schematic diagram of a 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 : 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.

[0025] 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; 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 not adjacent, then the topological relationship between the subway station room of type x and the subway station room of type y is not adjacent, then n xy =0; 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 according to the connection relationship, 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 .

[0026] Specifically, n is determined by sampling and calculating in 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.

[0027] S2. Determine the proxy points of each subway station room, set the constraints of each proxy point according to the topological relationship, and build a mechanical simulation system.

[0028] S21. Determine the proxy point of each subway station room and the area of ​​each subway station room, and use circles of different radii to represent the subway station rooms according to the area, taking the proxy point as the center of the circle.

[0029] 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.

[0030] S22. Setting the spring force between the proxy points according to the topological relationship.

[0031] 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, each is subject to the spring force applied by the other, for two non-adjacent subway station rooms, there is no spring force between them, and the closer the distance between the two adjacent subway station rooms, the stronger the spring force applied to each other. For example, for the i-th proxy point S i , which is related to the proxy point S j and proxy point S k are adjacent, then for the proxy point S i , which is affected by the proxy point S j Applied spring force F ij And the 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 .

[0032] 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.

[0033] The subway station boundary is the boundary of the area where the subway station room layout needs to be designed.

[0034] S24. Setting collision forces between proxy points so that circles to which proxy points belong do not overlap.

[0035] 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 circles they belong to come into contact, a collision force is generated, thereby moving the proxy point S i The circle and the proxy point S j The circle to which it belongs bounces away, thus avoiding the proxy point S i The circle and the proxy point S j The circles overlap.

[0036] Furthermore, before constructing the mechanical simulation system, it also includes: setting parameters of each proxy point and system parameters.

[0037] 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.

[0038] For example, the mass of each proxy point can be set to 1, the initial velocity of each proxy point can be 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 based on actual conditions. The initial energy of the system can be calculated based on the mass and initial velocity of each proxy point, and the calculation formula is as follows: ; Where E represents the initial energy of the system, i represents the i-th proxy point, l represents the total number of proxy points, and m i represents the quality of the i-th proxy point, v i Represents the initial velocity of the ith 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.

[0039] S3. Run the mechanical simulation system to obtain the final position coordinates of each proxy point.

[0040] Specifically, Figure 6 is a schematic diagram of the movement of proxy points in a mechanical simulation system provided by an embodiment of the present invention, Figure 7 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.

[0041] 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.

[0042] The present invention determines the connection relationship between the rooms in the subway station, and constructs a mechanical simulation system according to the connection relationship between the rooms in the subway station. The final position coordinates of each proxy point are obtained through the mechanical simulation system, and multiple layout plans can be automatically and quickly generated, so as to quickly find the optimal solution, which greatly shortens the design cycle. In addition, the data output by the mechanical simulation system can be stored, providing important reference information for subsequent maintenance and renovation work. In addition, when project requirements change, the subway room location design method based on the mechanical simulation system can also quickly recalculate and provide new layout plans, which facilitates the modification of room location layout and improves the adaptability of the design plan.
