In the traditional design process, designers use computer equipment to arrange and adjust pipelines of the MEP system one by one according to the design experience of the designers, so that the design of the MEP system is completed. However, the design of the MEP system using the method in the conventional art is inefficient. The embodiment of the invention provides a method and a device for generating an MEP system, computer equipment and a storage medium, and aims to solve the technical problems in the prior art.

The following describes the technical solution of the present invention and how to solve the above technical problems with specific examples.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

Fig. 2 is a schematic flow chart of a method for generating an MEP system according to an embodiment. The embodiment relates to a specific process of generating an MEP system by computer equipment according to a currently input design model and a beat unconstrained rule. As shown in fig. 2, the method includes:

Specifically, the computer device may receive a currently input design model, optionally, the design model may be input by a user through mouse click, or an identifier of the design model may be input by the user, and the computer device searches and imports the design model according to the identifier of the design model, which is not limited in this embodiment. The computer device may be based on a design instruction input by a user, optionally, the design instruction may be an icon corresponding to a certain MEP system type clicked by the user through a mouse, or an instruction for completing a previous design task, so as to determine the MEP type to be designed currently by the design model; and the computer equipment reads the input attribute of the design model, so as to obtain the attribute information of each equipment point corresponding to the MEP type to be designed in the design model.

Specifically, the computer device obtains a target configuration constraint rule of a target MEP topology corresponding to the MEP type according to the MEP type, wherein the target configuration constraint rule enables the target MEP topology to meet design requirements. It should be noted that each type of MEP system has its corresponding arrangement constraint rule according to its own characteristics. Optionally, the target arrangement constraint rule may include design criteria of the MEP system in industry design experience, for example, the arrangement constraint rule of the water path includes rules that the water pipe does not top when walking on the ground, and needs to be vertically arranged but cannot be horizontally arranged when walking on the wall.

Specifically, the computer device determines the positions of the starting point and the end point of the target MEP topology and the channel direction according to the pose of the device to be communicated and the type of the device point, wherein the channel direction can represent the wind direction in the pipeline of the wind-water-electricity system, the flow direction of water and the direction from the electricity taking end of the circuit to the electricity using end, for example, the computer device can calculate the target MEP topology meeting the distribution of the current device point by adopting a routing algorithm according to the type of the device to be communicated, the position and the posture orientation of the air conditioner, the end point of the circuit of the air conditioner, the type of the device as a distribution box, the position and the posture orientation of the distribution box and the starting point of the circuit of the distribution box, and combining the space environment of the design model, namely the space size and the specific orientations of the wall, the roof and the ground, and adopting a routing algorithm according to the target arrangement constraint rule, the chessboard-like rule and the obstacle avoidance rule of, the target MEP topology is the shortest path capable of meeting design requirements, and can effectively avoid obstacles for pipeline arrangement, for example, a bearing wall can be avoided when a circuit is arranged, so that slotting on the bearing wall is avoided. The chessboard-like rule may include at least one of a right-angle connection rule and a specific angle connection rule, and the chessboard-like rule does not accept connection according to any angle.

S104, generating an MEP system corresponding to each MEP type according to the target MEP topology corresponding to each MEP type and the bearing capacity requirement of each device to be communicated on the target MEP topology.

Specifically, the computer device can determine the bearing capacity requirement of the MEP pipeline where the to-be-communicated device is located according to the specification of each to-be-communicated device, for example, when the to-be-communicated device is a bedroom air conditioner, the specification of the air conditioner is 1P, and therefore the bearing capacity requirement of the to-be-communicated device is determined to be the minimum according to the specification that the air conditioner is 1P, and 1 ampere current work can be met; optionally, the computer device may further obtain the carrying capacity requirement of each device to be communicated according to information input by a designer, and the computer device determines the carrying capacity of each segment of pipeline according to the generated target MEP topology and the connection relation of each device to be communicated and by combining the carrying capacity requirement of each device to be communicated, thereby generating an MEP system corresponding to each MEP type meeting each device to be communicated.

In this embodiment, a computer device generates a target MEP topology corresponding to each MEP type in a design model according to a target arrangement constraint rule, a type of a device to be connected, a pose of the device to be connected, a type of the device point, a space environment of the design model, and a preset topology generation rule by obtaining an MEP type in a current design model and attribute information of each device point corresponding to the MEP type, and obtaining a target arrangement constraint rule of a target MEP topology corresponding to the MEP type, and generates an MEP system corresponding to each MEP type according to the target MEP topology corresponding to each MEP type and a load capacity requirement of each device to be connected on the target MEP topology, where the attribute information includes the type of the device to be connected at the device point, the pose of the device to be connected, and the type of the device point includes a start point and an end point, and the topology generation rules comprise chessboard-like rules and obstacle avoidance rules which meet the shortest path constraint. According to the method adopted by the implementation, the computer equipment can automatically generate the target MEP topology corresponding to each MEP type in the design model according to the MEP type in the current design model and the attribute information of each equipment point corresponding to the MEP type, the target arrangement constraint rule of the target MEP topology corresponding to the MEP type and the space environment of the current design model and the preset topology forming rule, and the computer equipment can also automatically generate the corresponding MEP system according to the target MEP topology corresponding to each MEP type and the bearing capacity requirement of each device to be communicated on the target MEP topology. Therefore, according to the method provided by the embodiment, a designer does not need to design the MEP system through a mouse or a keyboard and other manual operation modes, for example, the complicated operations such as manually setting the pipeline distribution trend one by one are performed, the MEP system corresponding to each MEP type can be automatically generated through a computer, the design efficiency is greatly improved, and design errors and design deviations caused by insufficient experience of the designer can be avoided, so that the design quality is greatly improved.

Optionally, on the basis of the foregoing embodiment, the computer device obtains the target configuration constraint rule of the target MEP topology corresponding to the MEP type, where one possible implementation manner may include: and searching the target configuration constraint rule from a preset first mapping relation according to the MEP type.

In this implementation manner, the computer device searches in the preset first mapping relationship according to the current MEP type to obtain a target configuration constraint rule corresponding to the current MEP type, where the target configuration constraint rule enables the MEP type corresponding to the target configuration constraint rule to meet the design criteria of the target configuration constraint rule, and for example, the target constraint rule may include the design criteria of an MEP system in national standards, international standards, enterprise standards, and industry design experience.

Optionally, on the basis of the above embodiment, the computer device obtains the target configuration constraint rule of the target MEP topology corresponding to the MEP type, and another possible implementation manner may include: and receiving the target arrangement constraint rule input by a user.

In this implementation, the target arrangement constraint rule may further include an arrangement constraint rule that the computer device receives user input, for example, a designer may select a target arrangement range through mouse click or the like, and set that the target MEP topology can cover the target arrangement range, and then the computer device sets the target arrangement range that is manually input as the required area of the target MEP topology as the target arrangement constraint rule.

Fig. 3 is a schematic flow chart of a method for generating an MEP system according to another embodiment. The embodiment relates to a specific process of generating a target MEP topology corresponding to each MEP type in a design model by computer equipment according to the design model and a preset topology forming rule. Optionally, on the basis of the foregoing embodiment, the foregoing S103 may include:

s201, generating a first communication topology set capable of enabling a plurality of equipment points to be communicated by adopting the chessboard-like rule and the obstacle avoidance rule according to the target arrangement constraint rule, the type of the equipment to be communicated, the pose of the equipment to be communicated, the type of the equipment points and the space environment of the design model, wherein the first communication topology set comprises a plurality of first communication topologies.

Specifically, according to the pose of the device to be connected and the type of the device point, the computer device firstly determines the position and the orientation of each device point to be connected in the MEP system and the type of the device point, namely, each device point is used as a starting point or a terminal point, secondly, the computer device adopts a shortest path algorithm meeting a chessboard-like rule in combination with the arrangement obstacles in the design model, and generates a plurality of first connection topologies in combination with a target arrangement constraint rule and the space environment of the design model, such as the distribution of walls, tops and ground, and the plurality of first connection topologies form a first connection topology set. For example, as shown in fig. 3a, the first topology set from point a to point B may include path 31, path 32, path 33, and so on. It should be noted that the arrangement obstacle is an area where the target MEP topology cannot be arranged, and the area may be an existing model area that cannot pass through the target MEP topology without meeting design requirements, or may be a space area that needs to be reserved, which is not limited in this embodiment.

S202, calculating the primary topology cost of each first connection topology in the first connection topology set; wherein the primary topology cost comprises: the cost of topology length and the cost of the number of topology inflection points.

Specifically, the computer device obtains the topology length and the number of topology inflection points of each first connection topology in the first connection topology set, so as to calculate the topology length cost and the topology inflection point cost respectively, and the topology length cost and the topology inflection point cost can represent the primary topology cost of each first connection topology. For example, in fig. 3a, the topology length of each of the path 31 and the path 32 is a + b, the number of topology inflection points is 1, the topology length of the path 3 is a + b1+ b2, and the number of topology inflection points is 2.

S203, selecting the target MEP topology from the first connection topology set according to the primary topology cost and a preset pipeline cost screening rule.

Specifically, the computer device selects one first connection topology which meets the design requirement and the design target from the first connection topology set as the target MEP topology according to the primary topology cost of each first connection topology and a preset pipeline cost screening rule. Alternatively, the design goal may be to minimize the out-of-turn or minimize the path length, which is not limited in this embodiment. The pipeline cost screening rule can comprise different material costs corresponding to different pipeline specifications and a cost proportional relation between pipelines with different specifications, for example, the cost of a three-meter water pipe is equal to that of a connecting piece; the method can also comprise corresponding relations between different pipeline topologies and work types and between the pipeline topologies and construction complexity, and the pipeline cost screening rule can combine the material cost and the work type of the different pipeline topologies and the construction complexity caused by the related work types, and calculate the primary topology cost according to preset weight.

For example, in fig. 3a, the topology lengths of the path 31 and the path 32 are a + b, the topology length of the path 33 is a + b1+ b2, and as can be seen from fig. 3a, b1+ b2 is b, so that the topology lengths of the path 31, the path 32 and the path 33 are the same, and since the number of topology inflection points of the path 31 and the path 32 is 1 and the number of topology inflection points of the path 33 is 2, it can be seen that the number of inflection points of the path 33 is greater than that of the path 31 and the path 32, so that the primary topology cost of the path 33 is higher than that of the path 31 and the path 32, and the primary topology costs of the path 31 and the path 32 are the same, and therefore, the computer device can optionally select the path 31 or the path 32 as the target MEP topology.

In this embodiment, the computer device generates a first communication topology set capable of communicating a plurality of device points by using a chessboard-like rule and an obstacle avoidance rule according to a target arrangement constraint rule, a type of a device to be communicated, a pose of the device to be communicated, a type of the device point, and a spatial environment of a design model, and calculates a primary topology cost of each first communication topology in the first communication topology set, thereby selecting a target MEP topology from the first communication topology set according to the primary topology cost and a preset pipeline cost screening rule. According to the method provided by the embodiment, the computer equipment can automatically generate a first communication topology set capable of communicating a plurality of equipment points according to a target arrangement constraint rule, the type of the equipment to be communicated, the pose of the equipment to be communicated, the type of the equipment points and the space environment of a design model by adopting a chessboard-like rule and an obstacle avoidance rule, and calculate the primary topology cost of each first communication topology in the first communication topology set, so that the target MEP topology is automatically selected from the first communication topology set according to the primary topology cost and a preset pipeline cost screening rule, the cost of the determined target MEP topology can meet the design requirement while the communication requirement is met, and the design quality of a design result is improved.

Optionally, as a possible implementation manner of S203, refer to the steps shown in fig. 4. Optionally, on the basis of the foregoing embodiment, the S203 may include:

S301A, determining the first connection topology with the lowest primary topology cost in the first connection topology set as the target MEP topology.

Specifically, the computer device ranks the plurality of first connection topologies in the first connection topology set according to a primary topology cost, and if the primary topology cost is the lowest single first connection topology, takes the first connection topology with the lowest primary topology cost as the target MEP topology. For example, in fig. 4a, the first connection topology set from point C to point D includes a path 41, a path 42, a path 43, and a path 44, and if an area E in the drawing is an obstacle, it is determined that the path 44 is the first connection topology with the lowest primary topology cost according to the primary topology cost of each path, and therefore, the path 44 is taken as the target MEP topology.

In this implementation, the computer device can use the first connection topology with the lowest primary topology cost as the target MEP topology according to the primary topology cost of each first connection topology in the first connection topology set, so that the target MEP topology meets the design requirement and has the lowest design cost, and further the cost of the MEP system is reduced.

Optionally, as another possible implementation manner of S203, refer to the steps shown in fig. 4. Optionally, on the basis of the foregoing embodiment, the S203 may include:

S301B, determining a second connection topology set from the first connection topology set according to the primary topology cost of each first connection topology; the second set of connected topologies comprises: the primary topology is the same cost and least costly part of the first connectivity topology.

Specifically, the computer device may rank, according to a primary topology cost of each first connection topology, each first connection topology in the first connection topology set, and select, as the second connection topology set, a part of the first connection topology with the smallest primary topology cost if the number of the first connection topologies with the smallest primary topology cost is more than one. For example, in fig. 3a, the path 31 and the path 32 are the first connected topology with the smallest cost of the primary topology, and therefore the path 31 and the path 32 are set as the second connected topology.

S302, determining the bearing capacity levels of different pipelines on each first communication topology in the second communication topology set according to the type of each equipment point on each first communication topology in the second communication topology set and the channel direction of each first communication topology in the second communication topology set.

Specifically, the computer device obtains a type of each device point on each first connection topology in the second connection topology set, and the computer device may further obtain a channel direction of each first connection topology in the second connection topology set, where the channel direction may represent a carrier flow direction in a corresponding pipeline, for example, in a circuit system, the channel direction may represent a direction from a power taking point to an electrical appliance; in the waterway system, the direction of the water in the water pipe flowing from the water taking point to the water using point can be represented. Generally, for an MEP system, carriers are input from a main input point and flow to each device to be connected in a design model step by step through a main pipeline and a plurality of pipelines erected layer by layer, and it can be understood that the carrying capacity of the MEP system changes correspondingly every time the MEP system passes through a device to be connected, and the carrying capacity level is reduced by one step. For example, as shown in fig. 3b, fig. 3b is a schematic diagram of a model of an air-path system of a room model, where 1 is an air inlet of a room, 2 is an air outlet, and the model of the air-path system has a plurality of air outlets. It should be noted that, in the air duct system, the air output of the air outlet can be subtracted from the air carrying capacity of the air duct every time the air outlet passes through one air outlet, and therefore, the carrying capacity level changes. Therefore, the computer device can determine the carrying capacity levels of different pipelines on each first communication topology in the second communication topology set, that is, which pipeline needs a large carrying capacity according to the type of each device point on each first communication topology and the acquired channel direction of each first communication topology in the second communication topology set.

It should be noted that, because the load bearing levels of different pipelines correspond to different load bearing costs, generally, the pipeline with a higher load bearing level has more equipment points at the rear end thereof and has a higher load bearing capacity, and the corresponding load bearing cost is also higher, whereas the pipeline with a lower load bearing level has fewer equipment points at the rear end thereof and has a lower load bearing capacity and a lower load bearing cost. Optionally, the bearing capacity levels of different pipelines may determine their corresponding bearing capacity levels through a corresponding relationship between the bearing capacity levels and the bearing capacity costs. Optionally, the correspondence between the load bearing level and the load bearing cost may be a one-to-one correspondence, a many-to-one correspondence, or a many-to-many correspondence; optionally, the list may correspond to the index, and the list may also correspond to the link, which is not limited in this embodiment.

For example, the computer device searches for a positional relationship with adjacent corners starting from each corner, determines whether the position of the corner can be adjusted if it is not on a horizontal or vertical line (relative to a local coordinate system, e.g., the coordinate system of a local network of pipes) based on the coordinate error of the corner, adjusts the alignment if it is adjustable, i.e., has no obstacle in the adjustment direction within the adjustment range, and the process may be repeated until all corners are adjusted in place or cannot be adjusted further. The preset topological adjustment rules comprise a material cost minimum rule and a pipeline construction cost minimum rule. Optionally, the computer device may calculate the bearing capacity cost comprehensively according to the preset weight on the basis of the material cost and the construction cost.
