Alternatively, a number of critical inflection points in the pipeline may be automatically generated by the a-algorithm. The A-algorithm is a search method for solving obstacle avoidance and searching a shortest path in a static road network. Specifically, the evaluation function expression of the a-algorithm is as follows: (n) ═ g (n) + h (n); f (n) is an estimate of the cost of reaching the target state from the initial state via state n; g (n) is the actual cost in state space from the initial state to state n; h (n) is the best path estimation cost from state n to the target state. By using the a-algorithm evaluation expression, a series of path key points (i.e., key inflection points in the pipeline layout path required by the embodiment of the present invention) can be calculated.
Further, after the inflection points in the pipeline layout path are determined, the inflection point information of the inflection points is found from the obtained modeling data. Wherein, the inflection point information includes, but is not limited to, inflection point coordinates, inflection point direction, inflection point pipe diameter, etc.
And S204, generating a pipeline primary model according to the information of the pipeline head, the pipeline tail and the pipeline key point and by combining a pipeline selection rule.
Optionally, the pipeline selection rule is: pipe guidance pipeline rules and end-to-end connection rules.
In some embodiments, generating a pipeline preliminary model based on pipeline head, pipeline tail, and pipeline keypoint information in combination with pipeline selection rules comprises: extracting key points in the pipeline layout path according to the pipeline key point information; calculating a key point angle in a pipeline arrangement path; determining the type of the pipe fitting according to the key point angle; setting the inlet and outlet directions of the pipe fittings according to the connection rules of the head part, the tail part and the head and the tail of the pipeline; after the arrangement of the inlet and outlet directions of the pipe fittings is finished, the pipeline modeling is finished according to the pipe fitting guide pipeline rule, and a pipeline primary model is generated.
It should be noted that each pipe has its characteristic points, including: the origin (PO) of the pipe, the arrival point (ARRIVE point, also defined as point P1) of the pipe, and the departure point (LEAVE point, also defined as point P2) of the pipe, the origin being the reference point of the pipe, the arrival and departure points defining the connection point and determining the direction of flow of the pipe medium through the pipe. Therefore, in order to ensure the correctness of the medium flowing direction in the pipeline, the embodiment of the invention adopts an end-to-end connection mode to define the connection of the pipe fittings, and the connection of the pipe fittings and the pipe fittings is the connection of an ARRIVE point and a LEAVE point. Furthermore, the data management of the pipeline adopts a tree structure hierarchy, and the pipe fittings under the pipeline are arranged in sequence according to the flow direction of the pipeline.
Based on the above principle, the embodiment of the present invention can perform automatic pipe modeling after determining the pipeline head, the pipeline tail, and the key points in the pipeline layout path. It should be noted that the critical point in the pipeline layout path is the aforementioned inflection point in the pipeline layout path.
Specifically, first, the keypoint angle is calculated. The key point angle is an included angle formed by a straight line where the current key point and the previous key point adjacent to the current key point are located and a straight line where the current key point and the next key point adjacent to the current key point are located. Wherein, the current key point is any one key point of all key points in the pipeline layout path.
Secondly, according to the pipe diameter size of pipeline, consider key point angle size simultaneously, select different pipe fitting types. The pipe types include, but are not limited to, welds, bends, elbows, and the like.
As shown in fig. 3 to 5, schematic diagrams are selected for the pipe type.
Wherein, when the pipe diameter is less than or equal to 10, the bent pipe fitting under the same grade can be directly selected.
Referring to fig. 3, fig. 3 is a schematic view of an alternative type of pipe having a pipe diameter greater than 15 and less than 50.
As shown in fig. 3, in the pipe diameter range, when the key point angle is 0-2 degrees, the type of the pipe fitting is a welding point; when the angle of the key point is 43-45 degrees, the selectable type of the pipe fitting is a 45-degree elbow; when the key point angle is 88-90 degrees, the selectable pipe fitting type is a 90-degree elbow; when the key point angle is other angles, the tube type of choice is a bent tube.
Referring to fig. 4, fig. 4 is a schematic view of an alternative type of pipe having a pipe diameter greater than 50 a and less than 100 a.
As shown in fig. 4, in the pipe diameter range, when the key point angle is 0-2 degrees, the selectable pipe type is a welding point; when the angle of the key point is 2-45 degrees, the selectable type of the pipe fitting is an elbow; when the key point angle is other angles, the tube type of choice is a 90 degree bend.
Referring to fig. 5, fig. 5 is a schematic view of an alternative type of pipe having a pipe diameter greater than 100 a.
As shown in fig. 5, in the pipe diameter range, when the key point angle is 0-2 degrees, the selectable pipe type is a welding point; when the angle of the key point is 2-30 degrees, the selectable type of the pipe fitting is a bent pipe; when the angle of the key point is 30-45 degrees, the selectable type of the pipe fitting is a 45-degree elbow; when the key point angle is 45-120 degrees, the selectable pipe fitting type is a 120-degree elbow.
And then, after the type of the pipe fitting is determined, the inlet and outlet directions of the pipe fitting are set according to the head-tail connection rule. Specifically, the direction of the ARRIVE point of the first key point is consistent with the direction of the head of the pipeline, and the direction of the LEAVE point of the first key point is consistent with the PO direction from the LEAVE point to the second key point; the direction of the ARRIVE point of the second key point is consistent with the direction of the LEAVE point of the first key point, and the rest is repeated until the arrangement of the inlet and outlet directions of all the pipe fittings is finished.
And finally, automatically creating and generating a pipeline preliminary model according to the pipeline guiding principle after the arrangement of the inlet and outlet directions of all the pipe fittings is finished.
And S205, acquiring the online equipment according to the modeling data.
Specifically, the online device list is included in the obtained modeling data, so that the online device and the related information thereof can be extracted according to the modeling data. In-line devices include, but are not limited to, valves, tees, manifold seats, and the like. The related information of the online devices includes, but is not limited to, the sequential logic order of the online devices in the pipeline, etc.
Step S206, the position of the online equipment is determined in the pipeline preliminary model.
In some embodiments, determining the location of the online device in the preliminary model of the pipeline includes: acquiring the logic relation of the online equipment in the pipeline according to the modeling data; determining the position of the online equipment according to the logical relation of the online equipment in the pipeline; the position of the online equipment is the position of a key point of the online equipment in the pipeline preliminary model.
In some embodiments, after determining the online equipment, distance information is set for the online equipment from the pipe in the preliminary model of the pipeline, e.g., the distance from the bend to the online equipment is set to 300; the online device to online device distance is set to 500. Further, the on-line equipment is sequentially placed into the straight pipe section according to the sequential logic sequence of the on-line equipment in the pipeline, wherein the distance of placement is not only required to meet the set basic distance, but also the distance included by the heat preservation thickness is required to be added to the on-line equipment with the heat preservation thickness, and if the current straight pipe section cannot be placed, the next straight pipe section is sequentially placed, and the like is carried out until all the on-line equipment are placed into the corresponding pipe sections according to the selected logic relationship. The heat preservation thickness is that some need keep warm or keep cold according to the medium difference in the pipeline, and the medium that needs the heat preservation needs to increase the heat preservation in the pipeline I, and the thickness of this heat preservation is heat preservation thickness promptly.
And step S207, generating a three-dimensional pipeline design model.
Specifically, after the position of the in-line device is determined in the pipeline preliminary model, a three-dimensional pipeline design model can be generated.
And S208, carrying out pipeline gradient setting on the three-dimensional pipeline design vinegar.
In some embodiments, performing the pipeline grade setting on the three-dimensional pipeline design model comprises: setting the gradient of the placing slope; defining the direction of the pipeline head according to the gradient; and determining the direction of slope releasing of each pipeline according to the defined direction of the pipeline head, and finishing the slope setting of the pipelines. Wherein the release slope may be set manually.
In some embodiments, determining the direction in which each pipe is to ramp, based on the defined direction of the pipe head, comprises: acquiring inflection point information of all inflection points of all pipelines in the pipeline arrangement path; comparing the elevation information of all inflection points; determining a key inflection point according to the comparison result of the elevation information; comparing elevation information of the key inflection points; and determining the direction of each pipeline slope according to the comparison result of the elevation information of the key inflection point.
Specifically, after inflection point information of all inflection points of all pipelines is collected, the elevation information of all inflection points is compared, the inflection points with the front and back elevation changes are extracted according to the comparison, the inflection points with the front and back elevation changes are defined as key inflection points, and then the elevation information of the key inflection points is compared one by one. If the elevation of the current pipeline inflection point is higher than the elevation of the next pipeline inflection point, the slope releasing direction between the two key inflection points is from high to low; if the elevation of the inflection point of the current pipeline is lower than that of the next pipeline inflection point, the slope releasing direction between the two key inflection points is from low to high.
