Description

Method and system for solving problems found in pipeline integrated design

Technical Field

The present disclosure relates to the field of integrated design of underground pipelines, and more particularly to a solution to the problems found when integrated design of pipelines is performed.

Background

In recent years, with the progress of society, urban construction and reconstruction projects are increasing across the country. And the comprehensive design of municipal pipelines is an indispensable content in the overall planning construction of cities. Urban underground exists in a variety of engineering and municipal pipelines, such as water, gas, communication, electricity, rain, sewage, and the like. The pipelines are distributed in all corners of a city in a star-chess way, the performances and the purposes of the pipelines are different, the pipelines are not the same department in design and construction, and the construction time is usually prior and later. Therefore, when planning and designing before construction, the comprehensive design of the space positions of various municipal pipelines is very necessary, which can prevent and solve the problems possibly occurring between new pipelines and old pipelines, between new pipelines and between pipelines and buildings in urban construction, and also facilitates the subsequent management and maintenance of the built pipelines in the future.

In the conventional pipeline integrated design scheme, a few software which can be used for the pipeline integrated design has been developed, and the software also provides a certain means for detecting and solving the pipeline problems (such as collision, non-compliance with specifications and the like), but the means for solving the problems in the conventional pipeline integrated design scheme is relatively single, and usually only one collision factor is considered or several factors are considered separately, so that the problems cannot be automatically solved through comprehensive and comprehensive analysis. For example, for a pipe collision problem at a point in the pipe design, the solution may simply suggest raising a pipe in the collision to avoid the collision, but the raising may cause many new problems to be raised, such as non-compliance, new collision problems with other previously non-colliding pipes, etc. Therefore, in the conventional pipeline integrated design scheme, various problems in pipeline design are still required to be finely adjusted step by relying on the manual experience of a designer until the pipeline adjustment overcomes the original problems and does not generate new troubles. This places considerable demands on the designer, requires significant effort and time from the designer, and is also a number of hazards. If the design is found to be problematic only by the field laying stage, a number of difficulties are presented to the construction.

For this reason, it would be desirable for a technician to provide a mechanism that quickly and automatically solves the problems found during the pipeline design stage.

Detailed Description

The present disclosure relates to a solution to the problem found in the integrated design of pipelines, which can quickly and automatically solve the problem (especially the collision problem) in the pipeline design that originally needs manual adjustment for many times, improve the reliability and accuracy of the pipeline design diagram, save the cost of construction and maintenance, and greatly improve the safety of the pipeline.

First, it will be appreciated that, when problems are found in the integrated design of pipes, such as collision problems between pipes, the most common solution is to solve the problems by adjusting one of the pipes so that the minimum spacing between the pipes meets the specifications. The pipe that needs to be tuned can be generally referred to as a "bypass pipe". And the adjustment of the conduit may include: lifting, lowering, installing curved tubes around the collided pipe, etc. It should be noted, however, that not all types of tubing can be bent. Many pipes, due to their nature, can only be lifted or lowered in their entirety, but cannot bypass other pipes that collide by bending. Therefore, before solving the pipeline design problem, it is necessary to classify various pipelines involved in the pipeline design drawing.

In particular, the current urban pipeline laying mainly involves six municipal pipelines in the municipal industry, namely water supply, gas, communication, electric power, rainwater and sewage pipelines.

Of these pipes, the water and gas supply pipe is typically a pressure pipe, which is bent by a bend, and thus belongs to a bendable pipe.

The communication and power pipelines are paved with cables rather than fluid, so that in order to avoid bending of the cables to influence signal transmission under a certain bending angle, the cables are generally paved in a direct-buried paving mode. However, the electrical and communication pipes may be laid through in some cases by means of parabolic pipes, so that these pipes belong to a pipe which is not easily bendable (but may also be conditionally bendable, for example by means of parabolic bent pipes, instead of right angle bends).

Whereas rainwater and sewage pipes belong to gravity flow pipes which cannot be bent due to gravity flow direction, otherwise fluid flow direction will be affected to cause rainwater and sewage to pool, and thus they belong to pipes which cannot be bent.

In the above case, the level of the rainwater, sewer pipes may be set to a high level, for example the first level. This level of tubing belongs to the inflexible tubing, and therefore, adjustment of this level of tubing can only take an overall lifting or lowering action. It is also generally not recommended to adjust this level of piping.

The power, communication pipe level is rated as a medium level, such as a second level. The level of tubing is typically only raised or lowered, but may be bend adjusted in some cases. For example, if the entire lifting or lowering of the pipe would hit an adjacent higher level pipe, such as a first level rain or sewage pipe, the course of the pipe at the point of impact could also be altered by adding, for example, a parabolic pipe, thereby bypassing the originally impacted pipe to avoid the impact.

Whereas the power cable, gas, water supply line are rated as low, for example third. When the pipeline of the level has problems, the measures of lifting, descending, bending and the like can be flexibly selected according to actual conditions so as to be adjusted as conveniently as possible.

It should be understood that the three-stage classification scheme described above is shown for illustrative purposes only and is not intended to be limited to only these three stages. The developer can further subdivide the various types of pipelines according to actual situations and requirements. For example, in some embodiments, in addition to the above-described classification levels of pipes, special types of pipes, such as avionics pipes, military communication pipes, etc., may be included in the pipe design diagram to be constructed, which are rarely found in conventional urban pipe complex designs, but their layout is generally not permitted to move due to the particularities of the pipes, and thus adjustments to this type of special pipe are not considered in the complex design of the pipe. They are set directly immovable and do not allow any adjustment thereof. The non-movable pipe for this type may be set to the highest level of non-movement, e.g. a "special" level.

In addition to the classification according to the pipe type as described above, the classification may be further performed by taking into consideration factors such as pipe diameter and properties. For example, a water supply pipeline which should be classified into a third class according to the type may be used in some cases as a main pipeline for a city, and thus, large-caliber pipelines such as 1 meter or more are used for these pipelines. At this time, it is particularly difficult to bend and bypass the pipeline (due to the increased difficulty of construction and hidden danger of damage to the valve and the joint at the bent port). Thus, it is possible to grade the pipe to the first or second level to avoid bending operations as much as possible. While small diameter water mains is not so problematic, it can be classified as a third class to allow for curved bypass laying.

In addition, if the types of the two collided pipelines are the same, the newly-built pipeline is preferentially selected as the avoidance pipe to be adjusted.

The classification of the pipeline is the basis for automatically adjusting the pipeline design. The subsequent adjustments are all raised, lowered and bent following the principles described above to solve the problem found.

After describing the pipeline classification, a block diagram of an example pipeline design system having functionality to automatically address the discovered design issues according to an embodiment of the present disclosure is described below.

As shown in fig. 1, the pipeline design system 100 includes: a data input module 102, a pipeline design module 104, a problem investigation module 106, a pipeline adjustment module 108, a user input module 110, and a design output module 112. The pipeline design system 100 may be implemented using existing personal computers, servers, notebooks, tablets, and specially designed computing devices, etc. The modules may be implemented by a processor, an ASIC, firmware, and software code stored therein, respectively, and will not be described in detail herein.

The data input module 102 is configured to receive data related to a pipeline design from various data sources. For example, a geophysical report of the current underground piping may be received from the project responsible party and a preliminary plan view for the corresponding type of piping received from each of the specialty companies (e.g., six municipal specialty companies, water, gas, communications, electricity, rain, sewage). These data relating to the pipe lay project are centrally output to the pipe design module 104.

The pipeline design module 104 is configured to process the received data to generate an original pipeline three-dimensional design map. The processing may include converting the geophysical reported pipeline data into a three-dimensional pipe network map, merging and triangulating the preliminary planning maps from each specialized company into an integrated three-dimensional planning map. And finally, combining the three-dimensional pipe network diagram and the integrated three-dimensional planning diagram into an original three-dimensional planning diagram. In this original three-dimensional design, not only the layout of the planned pipelines of the professional company is included, but also the survey status of the on-site pipelines provided by the geophysical prospecting report. Moreover, in the original three-dimensional design drawing, not only the pipeline designs provided by the respective specialized companies may have problems with each other after integration (since the newly built pipelines provided by the respective companies are generally the same trend, the problem of collision between them may be solved by slightly translating or moving up and down, which is not the focus of the present disclosure), but also the layout of the newly designed pipelines by the specialized companies and the existing pipelines in the geophysical prospecting report may have problems (particularly, there may be a problem of a few collisions with the current pipeline in the vertical direction when the newly built pipeline passes through the intersection). The original three-dimensional design is then output to the problem-solving module 106.

The problem-solving module 106 is configured to solve problems that may exist in the original three-dimensional design drawing according to certain policies, rules, standards, specifications. The problems can include two broad categories, collision problems and non-canonical problems. The collision problem may include: collision problems between the current pipeline and the newly laid pipeline, between the newly laid pipeline and surrounding buildings or obstacles, etc. Whereas non-canonical problems can include: pipeline laying is not in accordance with industry specifications, pipeline materials are not in accordance with surrounding environment requirements, pipelines and other various types of problems. Among these problems, the most difficult problem is the collision between the existing pipeline and the newly laid pipeline because it involves selecting which pipeline to adjust and how to adjust to solve the existing collision problem without creating a new problem. While the problem of collisions between the newly laid pipes, between the newly laid pipes and surrounding buildings or obstacles is much simpler. Accordingly, the collision problem to be solved described below is generally referred to as a collision problem between the existing pipeline and the newly laid pipeline. Each time the problem-solving module 106 finds a pipe-crash problem from the original three-dimensional design drawing, it generates a problem-solving report containing the pipe concerned, in which data associated with the found-crash problem, such as the pipe concerned, the type of crash, the location of the crash, etc., are recorded. After the issue troubleshooting report is generated, the issue troubleshooting report and the three-dimensional design drawing are submitted to a subsequent pipeline adjustment module 108. Alternatively, it is within the scope of the present disclosure that after all collision problems have been discovered by troubleshooting the entire design drawing, a comprehensive problem troubleshooting report containing all the problems may be generated.

At the pipeline adjustment module 108, after receiving the issue troubleshooting report, first, the type of pipeline involved in the issue troubleshooting report is identified using the pipeline classification module and classified according to the classification rules described above, thereby determining which of the involved pipelines is to be adjusted, i.e., which is the "bypass pipe". In some embodiments, the staged ducts may be identified in different colors in later designs, so that the stage of the duct may be more easily understood.

The path adjustment module of the pipeline adjustment module 108 starts to adjust the related pipeline according to the pipeline classification, and the path adjustment can adjust the path of the avoidance pipe according to a path diagram algorithm, wherein the path adjustment comprises lifting the pipeline as a whole, lowering the pipeline as a whole, or bending the pipeline around other collided pipelines at the collision position by adding bent pipes, valves and joints. Under the condition that the underground pipe network to be constructed is not dense, the problem of collision can be effectively solved by integrally lifting or descending, so that the underground pipe network to be constructed can be preferentially used. When underground pipe networks are dense, new collision problems are likely to be caused by overall lifting or descending, so that in this case, measures for locally bending and bypassing low-grade pipelines are preferably selected instead of overall movement, and the new problems caused by adjustment can be avoided to the greatest extent. The adjustment may be performed automatically according to the hierarchical adjustment rules and industry specifications described above, or semi-automatically with the intervention of a user (typically a designer). For example, when a variety of alternative adjustment schemes are available that are difficult to separate, the designer may manually select one of the various schemes provided by the system or fine tune the automatically selected scheme via the user input module 110. It should be understood that the user input module 110 and input from the user are not required. In most cases, there are no many alternative tuning schemes that are difficult to decide, and the pipeline tuning module 108 can automatically select the best tuning scheme to automatically tune the three-dimensional design drawing based entirely on the hierarchical tuning rules, industry specification requirements, and tuning path diagram algorithms described above. The specific tuning process will be described in further detail below in connection with specific examples. After the current collision problem is resolved by automatic adjustment, the pipeline adjustment module 108 notifies the problem-solving module 104 to continue to solve the next collision problem or to select the next collision problem from the comprehensive problem-solving report, and after the problem is found, continues to execute the steps of classification and adjustment described above until the problem-solving module 104 can not find a new collision problem in the three-dimensional design drawing or all problems in the comprehensive problem-solving report.

In some embodiments, the pipeline adjustment module 108 may also place the adjustment step after the optimal path adjustment scheme has been generated for all collision issues. By integrating and optimizing these optimal path adjustment schemes for individual problems.

After no new problem is inspected in the three-dimensional design, the problem inspection module 106 notifies the pipeline adjustment module 108 that the problem inspection is completed. The pipeline adjustment module 108 provides the adjusted pipeline three-dimensional design map to the design output module 112.

At the design output module 112, the system may present the adjusted three-dimensional design drawing to a user, i.e., designer, in various forms for modification or adoption by the designer, using devices such as a display, printer, plotter, etc. connected thereto. So far, the operation flow of the whole pipeline design system is ended.

It will be appreciated that in some cases, the input module 102 and the pipeline design module 104 may be omitted if a designer or enterprise has designed a pipeline design drawing, but has not yet been troubleshooted. After troubleshooting the pipeline design with the troubleshooting module 106 and generating an troubleshooting report, the troubleshooting report is input to the pipeline adjustment module 108 for subsequent adjustment to solve the problem without going through the comprehensive design phase. Also, in other embodiments, the input module 102, the pipeline design module 104, and the troubleshooting module 106 that collect pipeline data may be omitted. Because the designer can directly retrieve the pipeline design drawing from the system where the problem has been resolved to perform the adjustment without having to troubleshoot from scratch as described above. The pipeline design drawings that have been troubleshooted may be from other designers or provided by other design enterprises. Thus, in this case, the pipeline design system 100 need only read each collision issue in turn from the provided ready troubleshooting report and input it directly to the pipeline adjustment module 108 for subsequent adjustment to address the issue without going through the comprehensive design and issue troubleshooting phase.

Accordingly, the present disclosure focuses on how the pipeline adjustment module 108 performs pipeline adjustments to the pipeline design map. While the implementation of the pipeline design module 104 and the problem investigation module 106 may be accomplished using various urban pipeline design software that has been developed in the prior art, such as CAD software, civil 3D planning software, and the like.

For ease of understanding, the following description of several embodiments is provided for simplicity and brevity of disclosure of how the present disclosure may be implemented to automatically address the problems identified in the integrated design of pipelines.

First, taking the simplest case as an example, for a pipeline to be newly built (also referred to as a "new pipeline") under a road intersection and an existing laid pipeline (also referred to as a "current pipeline") have a collision problem (such as a cross collision, an indirect collision that does not meet a safe minimum distance, etc.), the following measures may be taken to solve the collision problem:

when the newly built pipeline grade is the first grade and the current pipeline is the second grade, the conclusion that the current pipeline of the second grade should be adjusted and moved is deduced according to the pipeline grading rule.

When the newly built pipeline grade is the first grade and the current pipeline is the third grade, the current pipeline of the third grade can be obtained according to the pipeline grading rule and is adjusted and moved.

When the newly-built pipeline is at the second level and the current pipeline is at the first level, a conclusion that the current pipeline at the first level is kept still and is adjusted by the newly-built pipeline at the second level can be obtained according to the pipeline classification rule;

when the newly built pipeline is of the second level and the current pipeline is of the third level, the current pipeline of the third level is generally adjusted according to the pipeline classification rule, but the judgment can be made manually as the case may be.

When the new pipeline is at the third level, and the current pipeline is at the first or second level, the design adjustment of the new pipeline corresponding to the third level can be judged according to the pipeline classification rule.

When the new pipeline and the current pipeline are the same in level, the collision problem is usually solved by mainly adjusting the design of the new pipeline according to construction experience.

These adjustment strategies described above are the basic criteria for a pipeline automatic adjustment scheme, on which the subsequent series of adjustments are based.

The following is an example of how the pipe adjustment may be performed in case of collision of the simplest two intersecting pipes, in order to facilitate a better understanding of the present invention by the skilled person.

As shown in fig. 2, it is assumed that a newly built pipe a collides with a current pipe B originally laid underground (e.g., a direct collision or both do not directly collide but the minimum distance is smaller than a prescribed threshold in industry specifications). According to the above procedure, first, the type of the pipe a and the type of the pipe B are identified based on, for example, data in the collision report, and it is determined which pipe needs to be adjusted (i.e., the "avoiding pipe") based on the identified types (see the adjustment policy above) with respect to each other. After judging the pipelines to be adjusted, the pipelines to be adjusted and the corresponding pipelines colliding with the pipelines to be adjusted can be respectively marked by special colors or legends in the design drawing so as to be convenient for the designer to distinguish.

Then, after the pipe to be adjusted is determined, the range (also referred to as "adjustment section") to which the pipe to be adjusted is to be adjusted, i.e. which section of the avoiding pipe to be adjusted is to be adjusted, is defined according to parameters such as the type, pipe diameter, type and attribute of the bent pipe, valve or joint to be used, and the like of the pipe a. This adjustment range can also be given automatically by the system based on previous experience of the length involved in adjusting the pipe in combination with the parameters described above. Of course, in some cases, the designer may also manually select the particular segment length to be adjusted based on system prompts.

After the adjustment range of the pipeline to be adjusted is selected, path calculation is performed according to the data in the minimum horizontal distance between engineering pipelines and between the engineering pipelines and building objects in the urban engineering pipeline comprehensive planning and the minimum vertical clear distance when the engineering pipelines cross, and the adjustment scheme of local bending up (bending lifting) or wearing down (bending descending) is performed on the pipeline part in the adjustment range of the pipeline to be adjusted, and the scheme is displayed on the design diagram in a mode such as a dotted line, a highlight or a shadow and the like which are easy to distinguish. The adjustment scheme may also include the height of the kick-up or the pull-down, the type of bend, valve, joint used, material and dimensions, etc. And the adjustment scheme need not be an exact value, but may comprise a suggested adjustable range within which the collision problem is solved as long as the adjustment section of the pipe that needs to be adjusted is placed.

In this way, the collision problem, which would otherwise require the designer to be able to be solved empirically through manual adjustment on the design drawing, can be automatically achieved with the solution of the present disclosure, and is greatly improved in both speed and accuracy.

The following describes the flow of a path diagram algorithm for adjusting the pipeline to solve the collision problem in detail in connection with the actual pipeline design diagram.

In fig. 3a, a plan view of a new pipeline K57-K70 is shown through three existing pipelines K90-K91, K71-K33, K100-K101. In fig. 3b, a three-dimensional perspective view of the four pipes of fig. 3a is shown to facilitate a more visual understanding of the spatial relationship between them.

For ease of illustration, among these pipes, the newly built pipes K57-K70 may be, for example, third-level water supply pipes, while the current pipes K90-K91, K71-K33, K100-K101 may be, for example, electric power, communication pipes, gas or sewage pipes. The type of the pipe is not limited thereto, and it may be determined which pipe is to be adjusted for different pipe types according to the above-described basic adjustment policy.

As shown in fig. 3b, the outside of both the dark newly built water supply pipe (K57-K70) and the light current pipe (K90-K91, K71-K33, K100-K101) are surrounded by a translucent cube area representing a detection area meeting the pipe clearance design requirements based on industry specifications. If other pipes are found in the detection area, it is also determined that a collision has occurred. Thus, it is also desirable to avoid any of the tuned conduits from entering the detection area of the other conduits during tuning.

Thus, as long as there is a conduit entering the detection zone of the other conduit, both conduits can be considered to have collision problems. In this example, K57-K70 and K100-K101 are detected as having a collision via a collision detection algorithm. It needs to be adjusted to avoid collisions.

First, the adjustment procedure knows the type of the crashed pipeline from, for example, a crash problem report or a three-dimensional design artwork, for example, K57-K70 is the third level of the water supply pipeline, and K100-K101 can be, for example, the second level of the communication pipeline. According to the foregoing adjustment strategy, the water supply pipe K57-K70 as a bendable pipe should be preferentially adjusted to avoid collision, and thus, the flow automatically selects K57-K70 as a pipe (i.e., an "avoiding pipe") to be adjusted.

After the avoidance tube is determined, the specific data of the other tubes (i.e., K90-K91, K71-K33, K100-K101) on the path through which the tube K57-K70 passes are then read from the three-dimensional design artwork or file, and the tubes K90-K91, K71-K33, K100-K101 are set as fixed tubes.

The critical path nodes on the paths of pipes K57-K70 are then analyzed. The critical path nodes refer to the points (such as points 1, 2 and 3 shown in fig. 3 c) with the minimum distance allowed by the avoidance pipes (K57-K70) between every two peripheral pipelines to pass (meet the clearance check requirement), and can also be remote free area points (such as point 4). Thus, by calculating the minimum spacing between the individual pipes in FIG. 3b, these critical nodes can be identified as shown in FIG. 3 c.

Next, a pipe path graph algorithm is started, which mainly selects the best path scheme as the adjustment scheme by analyzing various path schemes of pipes K57-K70 passing through four key path nodes 1, 2, 3, 4 from one endpoint x and reaching the other endpoint y. The length of the segment formed by the end point x and the end point y is the adjustment range of the segment required to be adjusted of the avoidance pipe according to the type, the pipe diameter, the type and the attribute of the bend pipe, the valve or the joint to be used and the like of the avoidance pipe, namely the length range of the segment required to be adjusted. The segment length (i.e., the positions of endpoints x and y) may be given automatically from an empirical library containing the parameters described above, or may be adjusted manually by the designer.

The specific path diagram is shown in fig. 3d, in fig. 3d various paths are drawn from endpoint x of the avoidance tube K57-K70 through one or more of the critical nodes 1, 2, 3, 4 to endpoint y. The adjusted avoidance pipe passes through the key nodes, so that the avoidance pipe is ensured to be outside the pipe clearance detection areas of other pipes, namely, the avoidance pipe after adjustment is ensured not to fall into the clearance detection areas of other pipes. As shown, there are 2 parameters on each path, which represent the number of bends and the length of the tube that need to be increased after selecting this path. It should be understood that the parameters on each of the paths are shown for illustration only and are not limited thereto. The bending number and the pipe length to be increased can be given according to the industry experience, i.e. a designer can formulate a path parameter table containing parameters of pipe type, pipe diameter, material, burial depth, minimum distance between other pipes, bending degree and the like according to the past pipe design avoidance experience, so that when the path diagram is generated by the flow, the path parameter table can be searched to give corresponding bending number and pipe length parameters for each path.

In combination with the above-mentioned path diagram, a description will be given of how to automatically select the adjustment scheme of the avoiding tube by the path diagram algorithm.

1) Starting from node x as a starting point, extending toward the next level node centered at the starting point, then extending toward the next level node centered at the next level node, and so on until extending to end point y. Then, the number of bends and the pipe length parameters are determined for each path by accessing the path parameter table. Thus, a path diagram as shown in fig. 3d is constructed. Note that in this figure, the path from endpoint x directly to endpoint y is actually the unregulated pipe itself, and therefore, this path is not considered in the calculation.

2) Subsequently, the algorithm introduces three sets S, U and a. The function of S is to record the nodes that have found the optimal path (not yet completed) and can save, for example, 3 paths with optimal scores. Multiple paths are recorded in the set S because the process setpoint for one optimal path may not be optimal. Also, it is to be understood that the three are for illustrative purposes only and are not limiting. And U is the node set of the optimal scheme for recording all the optional path nodes, and A is the node set of the optimal scheme for the path which is completed currently. The path selection flow includes: the last node of each optimal path in the set S is taken as a starting point to find out the next node which is optional from the last node from the set U (the next node must not appear in the current path, i.e. it is not possible to pass through the same node twice in a calandria scheme). Then, selecting the optimal three paths according to the score of each path in a plurality of paths from the last node to the optional next node, if the obtained path does not reach the node y, storing the optimal three paths into the set S, and if the completed path is obtained, comparing with the current optimal solution in the set A and updating the optimal solution in the set A. And then, taking the last node of each optimal path in the set S as a starting point, continuously obtaining the next node from the set U, and repeatedly executing the flow until the scores of the optimal paths in the set S are all larger than those of the optimal schemes in the set A, and ending the algorithm. At this time, the path reserved in the set a is the optimal path adjustment scheme.

Wherein, the main factors of the score of the path include:

(1) Shortest path: the sum of paths of the scheme passing through the nodes is shortest;

(2) Minimal distortion: the scheme passes as few path points as possible;

to calculate the shortest path and the least skew, the present approach may employ a weighted formula to calculate the path score, for example: (path score = number of path bends 5+ path pipe length). The formula is merely an example of calculating a path score and is not limited in this regard. According to this formula, the algorithm provides several relatively optimal paths for both nodes. For each path, a path score between two nodes is calculated according to the weighting formula, the smaller the score of the whole path is, the better the calandria path is represented, and the node and the path thereof can be preferably selected. Each time the next node is selected is an accumulated update of the path scores involved. Finally, during traversal, the scores are compared to discard some non-optimal paths, leaving the path with the lowest score as the best adjustment path.

The following is one example of calculating the best path adjustment scheme from the example path diagram of fig. 3 d:

initially, only the starting point x is in S; u is other nodes than x (e.g., nodes 1,2,3,4, y). Thus, the path from x as the starting point to each node in the set U and its score are as follows (where the score of the path = number of bends in the path 5+ path pipe length, light grey indicates the eliminated path):

The three optimal paths obtained after eliminating the paths (x- > 3) with high scores are x- >1; x- >2; x- >4, recording these nodes 1, 2 and 4 and their paths and scores into set S, and continuing the algorithm;

second, starting from the optimal paths in the set S, selecting the next possible node from the set U and calculating the score of the path (the score of the path containing the plurality of nodes = accumulation of the scores of each segment of the path, light gray represents the eliminated path, dark gray represents the selected optimal path):

the optimal path obtained after eliminating the path with high score is x- >1- >2; x- >1- >3; x- >4- >3, these nodes and paths are updated into set S. On the other hand, the optimal solution of the currently obtained completion path scheme is x- >2- > y, and the score of the optimal solution is smaller than that of x- >1- > y, so that the optimal solution is updated to the set A, and the algorithm is continued.

Third, starting from the last node of the optimal path in the set S, selecting the next possible node and calculating the score of the path (the score of the path containing multiple nodes = accumulation of the scores of each segment of path, light gray represents the eliminated path, dark gray represents the selected optimal path):

/>

the optimal path x- >1- >2- >3 is obtained after the paths with high scores are eliminated; x- >1- >3- >4; x- >4- >3- >1; updating the nodes and paths into a set S; the optimal solution x- >1- >2- > y of the completion scheme that has been obtained currently is better than the x- >2- > y saved in set a, so it is updated into set a. In addition, the score of the optimal path in the set S is higher than the score of the current optimal solution x- >1- >2- > y, and the score is only larger (less optimal) when the user continues to go on. Thus, the algorithm ends up with the resulting optimal adjustment path being the x- >1- >2- > y scheme. According to the path adjustment scheme, a three-dimensional spatial perspective view of the four pipes adjusted as shown in fig. 3e can be generated. It can be seen from the figure that the adjustment not only solves the original collision problem, but also causes the adjusted pipes K57-K70 to be outside the detection area of the other pipes without causing a new collision.

However, in most cases (e.g., where a new pipeline is to be laid at an intersection), the point of impact of the new pipeline with the current pipeline is likely not more than one. That is, in other embodiments, the conduit K57-K70 may collide with not only the conduit K100-K101, but also, for example, the conduit K90-K91 or the conduit K71-K33, and even with all three of the present conduits. Therefore, each time the newly built pipe collides with the current pipe crossing it, the collision needs to be analyzed according to the path diagram algorithm flow to generate an adjustment scheme as shown in fig. 3 e. After analyzing all the collision problems and generating corresponding adjustment schemes respectively, the system can integrate and optimize all the analyzed adjustment schemes, for example, reduce construction difficulty and improve safety of the pipeline by combining similar adjustment operations (for example, combining several adjacent sections of the same pipeline into a long section lifting operation), move the end points of the sections to be adjusted of the pipeline (for the adjustment operation of the adjacent pipeline, the length of the section to be adjusted of the current pipeline is prolonged or shortened), properly adjust pipeline objects to be adjusted (for example, if only a slight adjustment is needed for the second-level pipeline, a series of adjustment operations originally needed for the third-level pipeline is simplified, and corresponding adjustment can be selected for the second-level pipeline). The integrated optimization can be automatically performed by the system through comprehensive analysis of several adjustment schemes, and can also be realized by a designer manually combining, canceling, splitting and moving pipeline adjustment operations in one or some adjustment schemes through a user input module.

To facilitate an understanding of the aspects of the present disclosure, a conventional set of municipal plumbing planning schemes are shown in fig. 4. Although the plan is shown in a plan-like form in fig. 4, it should be understood that three-dimensional the plan is already a well-established technique in the field of pipeline design. The design used in the present application is also based on three-dimensional design. The design is shown here again in plan view for the sake of clarity and brevity only.

In this figure, it is assumed that it is necessary to lay a planned water supply pipe DN500 through an intersection (a borrelia road and a lisan road intersection), and the pipes intersecting the borrelia road are six kinds of pipes, i.e., a current power grid 21 hole, a current gas pipe DN200, a current sewage pipe DN300, a current rainwater pipe DN1000, a current water supply pipe DN500, and a current communication pipe, from left to right. In practical construction, since the rain water pipe and the sewage pipe are generally much deeper than the buried depths of other types of pipelines, the water supply pipe DN500 to be planned in theory can generally only generate no more than 4 collision points with other four current pipelines when the intersection passes through. But in the present disclosure, collision analysis was performed on all intersecting pipes for clarity. Between newly built pipes, however, there is generally no collision, since they are substantially parallel to each other.

According to the scheme of the present disclosure, after the original three-dimensional design drawing is obtained, first, it is necessary to detect a collision that may exist therein. For example, the collision detection function of the troubleshooting module 106 may read and identify burial depth data (mainly, a "vertical clearance" field) from a design drawing or a pipeline data table, and determine whether a collision exists according to the burial depth. Of course, the collision detection function can also detect non-contact indirect collision problems according to industry specifications. The following is an analysis of the planning water supply pipe and each current pipeline in the planning chart to illustrate how the present disclosure automatically adjusts the pipelines in the planning chart to solve the collision problem therein.

1. The collision is as follows:

1. water supply line DN500 and current situation communication pipe

As shown in an attribute table associated with the three-dimensional design drawing, newly built a water supply pipe DN500 (GS 14-GS 15) pipeline with a central burial depth of 1.4 meters and a pipe diameter of 0.5 meter, the burial depth of the top of the water supply pipe is known to be 1.15 meters; the current communication pipe (TX 5-TX 6) has a pipe center burial depth of about 1.0 m and a pipe height of 0.4 m, and the current communication pipe bottom burial depth is 1.2 m. Therefore, the collision of the bottom of the current communication pipe with the top of the newly-built water supply pipe can be deduced.

After the troubleshooting module 106 finds the collision, the troubleshooting report is provided to the pipeline adjustment module 108. Because the water supply pipe belongs to the third-level bendable pipe, and the communication pipe belongs to the second-level difficult-to-bend pipe and is laid in a direct-buried laying mode, when the new pipeline level is the third level, and the current collision pipeline is the second level, the pipeline classification module judges that the design adjustment is carried out on the third-level pipeline, namely the new water supply pipe, according to the adjustment strategy, namely the new water supply pipe DN500 (GS 14-GS 15) is used as the avoiding pipe.

Then, the path adjustment module automatically generates an adjustment area (which section is to be adjusted) to be adjusted on both sides of the collision point of the newly created water supply line DN500 (GS 14-GS 15), or let the designer select two nodes, such as GS14.1 and GS15.1, respectively, i.e., the endpoint x and the endpoint y in the path diagram algorithm. And then determining key nodes in the three-dimensional space of the pipeline related to the key nodes according to the path diagram algorithm, and constructing a corresponding path diagram based on the end points and the key nodes. Then, traversing the path graph, calculating and accumulating the scores of the paths according to a weighted formula, and finally, automatically selecting the path with the lowest score as the optimal path adjustment scheme. In this example, newly built water up pipe section DN500 (GS 14.1-GS 15.1) automatically curves up by selecting the path of the smallest distance according to the pipeline path score. The system may then automatically make corresponding adjustments to the design drawings and display them to the designer. Alternatively, when there are a plurality of path schemes with equal or similar scores, the designer is requested to select one path therefrom as a final adjustment scheme through the user input module 110. Still alternatively, the system may present the path adjustment scheme to the designer waiting for the designer to make fine adjustments or confirmation via the user input module 110 before making the corresponding automatic adjustments to the design drawing. So far, the problem of collision between the newly-built water supply pipe DN500 and the current communication pipe is solved.

2. New construction upper water pipe DN500 and current situation power grid 21 holes

The embedded depth of the center of a newly built water supply pipe DN500 (GS 14-GS 15) pipeline is 1.4 m, and the pipe diameter is 0.5 m, so that the embedded depth of the top of the water supply pipe is 1.15 m. The current power grid (DL 6-DL 7) has a pipe depth of about 0.8 m and a pipe height of 0.9 m, and the current power grid has a pipe bottom depth of 1.25 m. Therefore, the current situation that the bottom of the power grid tube collides with the top of the newly-built water supply tube can be deduced.

Because the water supply pipe belongs to the third-stage bendable pipe. The power grid is laid in a direct-buried laying mode, belongs to the second level and belongs to a pipe which is not easy to bend. Therefore, when the new pipeline level is the third level and the current pipeline is the first or the second level, the pipeline classification module judges that design adjustment should be performed by the new water supply pipeline DN500 (GS 14-GS 15) of the third level.

As described above, the adjustment is also to first determine the adjustment areas to be adjusted on both sides of the collision point, that is, two nodes GS14.2 and GS15.2 are selected on both sides of the collision point (that is, the end point x and the end point y in the path diagram algorithm). And then determining key nodes in the three-dimensional space of the pipeline related to the key nodes according to the path diagram algorithm, and constructing a corresponding path diagram based on the end points and the key nodes. Then, traversing the path graph, calculating and accumulating the scores of the paths according to a weighted formula, and finally, automatically selecting the path with the lowest score as the optimal adjustment scheme. In this example, newly created header DN500 (GS 14.2-GS 15.2) automatically rolls down the path selecting the minimum spacing according to the calculated path score. The design drawings are then automatically adjusted or presented to the designer for reference according to the adjustment scheme as described above.

2. No collision:

1. newly-built water supply pipe DN500 and current sewage pipe DN300

The embedded depth of the center of a newly built water supply pipe DN500 (GS 14-GS 15) pipeline is 1.4 m, and the pipe diameter is 0.5 m, so that the embedded depth of the top of the water supply pipe is 1.15 m. The current sewage pipe DN300 (WS 6-WS 7) has a central burial depth of about 0.65 m and a pipe height of 0.3 m, and the current sewage pipe bottom burial depth is 0.8 m. Since there is a sufficient distance (1.15-0.8=0.35 meters) between the bottom of the current sewage pipe and the top of the newly built water supply pipe, there is no collision between them and no avoidance is required.

2. New construction of upper water pipe DN500 and current rainwater pipe DN1000

The embedded depth of the center of a newly built water supply pipe DN500 (GS 14-GS 15) pipeline is 1.4 m, and the pipe diameter is 0.5 m, so that the embedded depth of the top of the water supply pipe is 1.15 m. The current dip pipe DN1000 (YS 23-YS 24) has a central burial depth of about 0.6 m and a pipe height of 1 m, and the current dip pipe has a pipe bottom burial depth of 1.1 m. Because the existing rainwater pipe bottom and the newly-built water supply pipe top have a sufficient distance (1.15-1.1=0.05 m), the rainwater pipe bottom and the newly-built water supply pipe top have no collision and do not need to avoid.

3. New up-flow pipe DN500 and current gas pipe DN200

The embedded depth of the center of a newly built water supply pipe DN500 (GS 14-GS 15) pipeline is 1.4 m, and the pipe diameter is 0.5 m, so that the embedded depth of the top of the water supply pipe is 1.15 m. The current gas pipe DN200 (RQ 2-RQ 3) has a pipe center burial depth of about 0.9 m and a pipe height of 0.2 m, and the current gas pipe bottom burial depth is 1 m. Because the existing gas pipe bottom and the newly-built water supply pipe top have a sufficient distance (1.15-1=0.15 m), the gas pipe bottom and the newly-built water supply pipe top have no collision and do not need to avoid.

4. New up-flow pipe DN500 and current up-flow pipe DN500

/>

The embedded depth of the center of a newly built water supply pipe DN500 (GS 14-GS 15) pipeline is 1.4 m, and the pipe diameter is 0.5 m, so that the embedded depth of the top of the water supply pipe is 1.15 m. The current water supply pipe DN500 (GS 55-GS 56) has a pipe center burial depth of about 0.95 m and a pipe height of 0.5 m, and the current water supply pipe bottom burial depth is 1.2 m. Although in theory, the problem of collision should exist due to collision between the bottom of the current water supply pipe and the top of the newly-built water supply pipe, in the design, the newly-built water supply pipe and the current water supply pipe are originally designed to be connected so as to be convenient for water supply, and therefore, the pipelines at the collision point part can be mutually connected through the joint and the valve, so that avoidance is not needed.

It should be noted that, although in this example, no collision of the same-level pipes occurs (the connection relationship between the water supply pipes is not the collision relationship), if such a collision occurs, the principle of moving the new and old pipes for the same-level pipes is generally followed, i.e., if the new pipe level of the collision is equal to the current pipe level, it is preferable to adjust the new pipe while maintaining the old pipe unchanged.

It is also noted that although in the above examples the detection of collisions is in terms of the burial depth spacing between the top and bottom of the pipe, this is for clarity of illustration only, as well as ease of understanding. Indeed, many more factors may be considered to determine whether a collision exists, such as industry specifications, materials used, geology, environment, and other factors. However, detecting a collision is not an issue in the present disclosure, and thus, is not described in further detail. Conventional methods, devices, software, programs, techniques and means for troubleshooting collision problems may be used to implement the problem-troubleshooting modules described in this disclosure.

In addition, special piping, such as military piping and critical piping, is not involved in the above examples. Although there is little chance of encountering these specialty pipes, once encountered, all other types of pipes should avoid the specialty pipe because the specialty pipe is the highest grade. The avoidance adjustment is similar to the avoidance adjustment scheme described above for these pipes and will not be described in detail herein.

In some embodiments, when an optimal path adjustment scheme for a collision is selected based on the path weighting score, the scheme need not be used for modification of the design drawing immediately. Instead, after analyzing all collision problems and generating corresponding path adjustment schemes, the system may integrate and optimize all analyzed adjustment schemes, for example, by merging similar adjustment operations (e.g., merging several adjacent sections of the same pipeline into a long lifting operation), to reduce construction difficulty and improve pipeline safety, moving the end points of the pipeline in the range of sections to be adjusted, properly adjusting the pipeline objects to be adjusted, and so on. The integration optimization can be automatically performed by the system through analysis of several adjustment schemes, or can be realized by a designer manually merging, undoing, splitting, and moving pipeline adjustment operations in one or some adjustment schemes through a user input module. For example, assuming that in the above example municipal pipeline planning and design diagram, for the collision problem of the water supply pipe DN500 and the current communication pipe and the collision problem of the newly built water supply pipe DN500 and the current power grid 21 hole, the two obtained final path solutions are both avoided by bending up the water supply pipe adjusting sections with partial overlapping (or no overlapping but very adjacent) to a similar height, the two path solutions can be finally combined to directly bend up all the involved water supply pipe adjusting sections integrally, i.e. bending up once to replace the original bending up twice. Therefore, the construction difficulty can be reduced, the materials can be saved, and the safety can be improved.

While in the specific example above, path adjustments are performed once every time a collision problem in the design is found, it should be appreciated that in some embodiments, the path map algorithm described above may be performed sequentially for all of the collision problems in the design after they are first discovered, and finally, the path adjustment schemes may be integrated and optimized to generate the final adjusted three-dimensional design of the pipeline. This is not essentially different from the embodiments described above.

Having described the basic principles and specific embodiments of the pipeline tuning scheme of the present disclosure, in FIG. 5, a method for solving problems found in pipeline integrated designs is illustrated in accordance with one embodiment of the present disclosure. According to the method, the pipeline paths in the three-dimensional pipeline design drawing can be automatically adjusted to solve the problem of the checked collision without manual participation. Furthermore, a quick, efficient and low-cost comprehensive design and adjustment scheme for the pipeline is provided.

In step 510, an original three-dimensional design of the pipeline is obtained from each source. The sources may include three-dimensional design drawings provided by the construction party, provided by the design company, or generated by the pipeline design module 104 of the system from geophysical reports and professional company planning drawings received by the data input module 102. There are many pipe collision problems in the original pipe three-dimensional design that need to be addressed.

Next, at step 520, the issue investigation module 106 begins to investigate the pipe-to-pipe collision issue that exists in the three-dimensional design drawing, which may be a direct collision issue between pipes, or an indirect collision issue between pipes that is not collided but the spacing does not meet industry specifications. If a collision problem between pipes is detected from the design drawing, it proceeds to step 530. If no new collision problem is found in the troubleshooting plan, proceed to step 560. See in particular the foregoing

At step 530, the pipeline classification module of the pipeline adjustment module 108 begins classifying and comparing pipeline types involved in the identified collision problem according to a basic pipeline adjustment strategy and selects a pipeline with a lower level as the avoidance pipe that needs to be adjusted. The path adjustment module of the pipeline adjustment module 108 then generates a path graph containing keypoints and end points based on the specific data of the pipeline concerned, and selects the optimal path adjustment scheme for the avoidance pipe based on the path graph adjustment algorithm as described above. As mentioned above, the optimal path adjustment scheme may be automatically selected according to the path score calculated by the path parameter-based weighting algorithm in the path diagram (please refer to the content related to the path diagram algorithm), or one of the various alternatives provided by the system may be manually selected or fine-tuned by the user (designer) through the user input module 110 in step 550, but step 550 is not required. After generating the optimal path adjustment scheme for the current collision problem, the pipeline adjustment module 108 may adjust the three-dimensional design drawing based on the path adjustment scheme, or may also leave the path adjustment schemes for all the problems to be generated and adjust together. Subsequently, the flow returns to step 520 to check for the next collision problem.

If a new collision problem is found at step 520, the above steps 530, 540 and 550 are continued to be performed to generate a corresponding path adjustment scheme to solve the new problem. This loops until no new problems are detected in step 520.

As previously described, when no new collision problem is found in step 520, flow proceeds to step 560. At this step, the respective path adjustment schemes generated for the respective collision problems may be aggregated, integrated, and optimized. The integrated optimization may include merging homogeneous operations, optimizing the adjustment range of the pipeline, properly adjusting the pipeline objects that need to be adjusted, and so on. The integrated optimization can be automatically performed by the system through comprehensive analysis of several adjustment schemes, and can also be realized by a designer manually combining, canceling, splitting and moving pipeline adjustment operations in one or some adjustment schemes through a user input module.

After the integration optimization is completed, the final adjusted three-dimensional pipeline design drawing is provided to the user (designer) through the design output module at step 570. After auditing and adjusting the final design drawing, the designer can send the final design drawing to constructors for project construction.

Compared with the existing scheme which mainly relies on manual adjustment of the problems in the pipeline design, the pipeline design adjustment scheme fully utilizes the processing capacity of computing resources to replace manual labor, improves efficiency, saves resources, improves safety, and avoids omission and errors which are easy to occur during manual adjustment. Thus, the integrated pipeline design scheme of the present disclosure is more flexible and efficient.

The foregoing has described certain embodiments of the present disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims can be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results.

Furthermore, it will be appreciated by persons skilled in the relevant art that various modifications in form and detail can be made to the described embodiments without departing from the spirit and scope of the disclosure as defined by the appended claims. Thus, the breadth and scope of the present disclosure should not be limited by any of the above-described exemplary embodiments, but should be defined only in accordance with the following claims and their equivalents.
