Description

Technical Field

[0001] The present invention relates to the technical field of engineering data management, and in particular to a mechanical and electrical pipeline data processing system and method based on a BIM model. Background Art

[0002] With the development of digital information systems, the management of electromechanical pipeline information has gradually developed into management through digital information systems. For example, the electromechanical pipeline drawings are digitally stored, and the digital model of the electromechanical pipeline is established through data simulation. Usually, the model of the electromechanical pipeline is related to the actual proportion of the pipeline during the design process, while the connection model between electromechanical equipment adopts a logical model, in which the actual parameters only appear as annotations, so it is difficult to match the two models one by one. In the process of matching the connection model between electromechanical equipment to the pipeline model, the connection result will be different from the actual due to insufficient information. For example, the pipeline through which the cable passes does not comply with the relevant regulations in the project or the cables in the pipeline exceed the capacity of the pipeline. Therefore, relevant staff need to invest a lot of time to correct the generated cable path. Summary of the invention

[0003] The purpose of the present invention is to provide a BIM model-based electromechanical pipeline data processing system and method to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a method for processing electromechanical pipeline data based on a BIM model:

[0006] Step S200: During the pipe threading operation, the cable attributes of the electromechanical cables that have passed through the pipe are recorded to obtain the pipe state set of the pipe, and the pipe threading operation records of the relevant staff at the bifurcation of the pipe are obtained. By comparing the pipe state sets of the pipes selected by the relevant staff and the pipes not selected, the conflict judgment conditions of the cable attributes are obtained;

[0007] Step S300: taking the currently ongoing electromechanical cable laying project as the target project, obtaining the correspondence between the topological map of the electromechanical equipment in the target project and the operation position in the pipeline map of the pipeline, taking a certain electromechanical cable in the target project as the first target cable, collecting the pipelines that meet the first target cable passing conditions, and obtaining the first target path;

[0008] Step S400: obtaining the operation sequence of the target project, obtaining the electromechanical cable that is passed through the pipe after the first target cable as the second target cable, obtaining the overlapping area of ​​the first target path and the second target path, and judging whether the second target cable conflicts with the existing cable in the overlapping area according to the cable attributes, and collecting the conflicting segments into a conflict pipeline sequence;

[0009] Step S500: According to the order of pipeline segments in the conflicting pipeline sequence, several segments are obtained to form a first conflicting section and a second conflicting section respectively, and the cable detour paths and the overall detour paths of the first conflicting section and the second conflicting section are obtained respectively, and the detour path with the shortest distance is selected as the detour plan for the conflicting section.

[0010] Furthermore, step S100 includes:

[0011] Step S101: obtaining a certain electromechanical device from the electromechanical cable laying operation record, obtaining the electromechanical cable corresponding to the certain electromechanical device, and obtaining the cable properties of the electromechanical cable, wherein the cable properties include the physical properties and specification properties of the cable;

[0012] Step S102: Obtain a pipe threading operation record of a certain electromechanical equipment in the electromechanical cable laying operation record, arrange the pipes through which the corresponding cables of the certain electromechanical equipment have passed through according to the sequence of the pipe threading operations, and obtain a pipe threading operation sequence corresponding to the certain electromechanical equipment: (La1, La2, La3, ..., Lan), wherein La1, La2, La3, ... and Lan respectively represent the first section, the second section, the third section, ... and the nth section of the pipe that the corresponding cable of the certain electromechanical equipment has passed through in a certain pipe threading operation record;

[0013] Step S103: Obtain the pipeline attributes of each section of the pipeline in the pipeline threading operation sequence. The pipeline attributes include the physical attributes and specification attributes of the pipeline. The pipeline attributes of any section of the pipeline and the cable attributes of the electromechanical cable passing through any section of the pipeline are combined into a line-pipe relationship pair. The pipeline attributes corresponding to the n1th section of the pipeline in the pipeline threading operation sequence form a set AT. p n1, the cable attribute set AT of the electromechanical cables passing through the n1th pipe c n1, the cable attributes of the electromechanical cable form a line-pipe relationship pair (AT p n1, AT c n1);

[0014] Step S104: In the electromechanical cable laying operation record, collect the wire-pipe relationship pairs corresponding to all electromechanical equipment, and collect the wire-pipe relationship pairs with the same pipeline attributes, where the pipeline attribute of the kth pipeline is recorded as AT p k, AT p The line-pipe relationship pairs corresponding to k are recorded as (ATp k, AT c k1), (AT p k, AT c k2), (AT p k, AT c k3), ... and (AT p k, AT c km), AT c k1, AT c k2, AT c k3, ... and AT c km represents AT p k corresponds to the 1st, 2nd, 3rd, … and mth cable properties;

[0015] Step S105: Obtain AT p The set AT of all cable attributes corresponding to k Ck , forming AT p k corresponding attribute relationship pair (AT p k, AT Ck ), where AT Ck =AT c k1∪AT c k2∪AT c k3∪……∪AT c km;

[0016] Pipes are classified according to their attributes, and historical data of pipe penetration of the same category of pipelines are collected. For a certain type of pipeline, which electromechanical cables are allowed to pass through and which are not allowed to pass through, the cable attributes of the electromechanical cables allowed to pass through are matched with the pipeline attributes to form a discrimination model for cables allowed to pass through a certain type of pipeline. When the cable attributes of the electromechanical cable are included in the cable attributes of the pipeline that meet the passing conditions, the corresponding electromechanical cable is allowed to pass through the pipeline;

[0017] Step S106: Obtain the cable attribute AT of any electromechanical cable c* , when AT c* It is AT Ck When a subset of is found, it is determined that any electromechanical cable meets the passing condition of the kth pipeline.

[0018] Further, step S200 includes:

[0019] Step S201: Set the pipeline state set of each pipeline section, collect the cable properties of the electromechanical cables passing through the pipeline into the pipeline state set corresponding to each pipeline section, and when the newly added electromechanical cables pass through any pipeline section, obtain the cable properties of the newly added electromechanical cables, collect them into the pipeline state set of any pipeline section, and complete the update of the pipeline state set of any pipeline section;

[0020] Step S202: obtaining an operation record of a certain bifurcation connection from the electromechanical cable laying operation record, the bifurcation connection includes 1 inlet pipe and d1 outlet pipes, obtaining the cable attributes of the electromechanical cable passing through the branch connection in the operation record, obtaining the outlet pipe that meets the cable attribute passing condition according to the pipe attributes of the outlet pipe, and gathering the outlet pipes into the candidate pipe set;

[0021] Step S203: obtaining a pipeline state set corresponding to each outlet pipeline in the candidate pipeline set before the operation record, obtaining the outlet pipeline selected by the relevant staff in the operation record, setting the outlet pipeline as the first target pipeline, and setting the pipeline in the candidate pipeline set that is not selected by the relevant staff as the second target pipeline. Before the operation record, obtaining the pipeline state set of the first target pipeline, recorded as ST1, and the pipeline state set of the second target pipeline, recorded as ST2;

[0022] Step S204: Calculate the conflict attribute set CF, CF = ST1-ST2, collect the cable attributes of the electromechanical cables passing through the branch connection in the action record to form a target attribute set, recorded as STc, record STc and CF as a conflict judgment condition, recorded as (STc, CF), collect all conflict judgment conditions to form a conflict judgment condition library;

[0023] For the multi-connected nodes of the pipeline, there are many possibilities for the laying of electromechanical cables. By capturing the historical records of pipeline selection by relevant staff, the pipelines selected by relevant staff are compared with those not selected, and the additional features of the unselected pipeline compared to the selected pipeline are used as conditions for determining that the cable cannot pass through the pipeline. Because the relevant personnel checked the additional features of the pipeline, they made the judgment not to select the pipeline.

[0024] Furthermore, step S300 includes:

[0025] Step S301: Obtain a pipeline diagram of pipelines in a target project and a topological diagram of connected electromechanical devices, take a certain electromechanical device in the target project as a first target device, and take an electromechanical cable corresponding to the first target device as a first target cable;

[0026] Step S302: In the topology diagram, the position where the first target cable enters the pipeline is taken as the first target starting point, and the position where the first target cable exits the pipeline is taken as the first target end point, and the first target starting point and the first target end point are marked in the pipeline diagram;

[0027] Step S303: Obtain the cable properties of the first target cable, record the path from the first target starting point to the first target end point in the pipeline diagram as the first target path, the first target path passes through the r1 section of the pipeline, wherein any section of the pipeline satisfies the passing condition of the first target cable, and the pipeline state set of the r1 section of the pipeline is updated through the cable properties of the first target cable.

[0028] Furthermore, step S400 includes:

[0029] Step S401: In the topology diagram, the position where the second target cable enters the pipeline is taken as the second target starting point, and the position where the second target cable exits the pipeline is taken as the second target end point, and steps S301 to S303 are repeated to obtain the second target path;

[0030] Step S402: Obtain all pipes that the second target path passes through, obtain the cable properties of the second target cable, perform conflict judgment on all pipes that the second target path passes through, and arrange the i-section pipes with conflicts in sequence according to the pipe threading order of the second target cable to obtain a conflicting pipe sequence.

[0031] Furthermore, step S500 includes:

[0032] Step S501: Obtain the first j sections of pipelines in the conflicting pipeline sequence to form the first conflicting section, j<i, obtain the pipeline starting point Ps1 of the first section of pipeline, and the pipeline end point Pe1 of the jth section of pipeline, in the second target path, record the path of all electromechanical cables between Ps1 and Pe1 as the first conflicting path, obtain the first detour path from Ps1 to Pe1, the first detour path does not include any section of pipeline in the conflicting pipeline sequence, and any section of pipeline passed by the first detour path meets the passing condition of the second target cable, obtain the length of the pipeline passed by the first detour path, recorded as G1;

[0033] Step S502: Obtain the first j+e sections of the conflicting pipeline sequence to form the second conflicting section, j+e≤i, e is a positive integer, the pipeline end point Pe2 of the j+e-th section of the pipeline, in the second target path, record the path of all electromechanical cables between Ps1 and Pe2 as the second conflicting path, obtain the second detour path from Ps1 to Pe2, the second detour path does not include any section of the pipeline in the conflicting pipeline sequence, and any section of the pipeline passed by the second detour path meets the passing condition of the second target cable, obtain the length of the pipeline passed by the second detour path, recorded as G2;

[0034] Step S503: when G1≥G2, using the second detour path as the detour path for detour around the second conflicting section;

[0035] Due to the design of the pipeline itself, which is affected by the engineering design and construction specifications, the detour distance of the electromechanical cables is not necessarily positively correlated with the length of the conflict range. It is possible that the detour distance generated by the overall rerouting of a longer section is smaller than that of a shorter area. The second conflict range includes the first conflict range;

[0036] When the detour distance of the shorter conflict range is greater than the detour distance of the longer conflict range, the detour solution corresponding to the longer conflict range is used as the adjustment path;

[0037] When G1<G2, obtain the pipeline starting point Ps3 of the j+1th pipeline section in the second conflict section, record the path of all electromechanical cables between Ps3 and Pe2 as the third conflict section in the second target path, obtain the third bypass path from Ps3 to Pe2, the third bypass path does not include any pipeline section in the conflict pipeline sequence, and any pipeline section passed by the third bypass path meets the passing condition of the third target cable, obtain the length of the pipeline passed by the third bypass path, and record it as G3;

[0038] Step S503: when G1+G3>G2, the second detour path is used as the detour path for detouring the second conflicting section; when G1+G3<G2, the first detour path is used as the detour path for detouring the first conflicting section;

[0039] The second conflict section includes the first conflict section and the third conflict section. When the first conflict section and the third conflict section are detoured respectively, the detour paths respectively detoured are summed. When the sum of the detour paths respectively detoured is greater than the length of the detour path of the same detour, the detour path of the same detour is used as the adjustment path.

[0040] When the sum of the detour paths of the respective detours is less than the length of the detour path of the same detour, it indicates that the detour solution of the first conflicting section is more reasonable. At this time, the first conflicting section obtains a detour path according to the first detour path, and the third conflicting section is used as a new first conflicting section. The process returns to step S501 and loops until there are no remaining pipelines in the conflicting pipeline sequence.

[0041] Step S504: After selecting the detour path, remove the detour pipes from the conflicting pipe sequence, update the conflicting pipe sequence, repeat steps S501 to S503, and when there are no remaining pipes in the conflicting pipe sequence, mark the pipe passage route of the second target cable in the pipe map as the pipe passage path.
