Embodiment
Be that example describes in detail to the present invention with a certain heavy construction below, its threedimensional model and construction plan all design and formulate based on this project.
Fig. 1 shows the process flow diagram of setting up the method for the four-dimensional model of engineering according to the embodiment of the invention.At first, the three-dimensional engineering model that utilizes design side design to accomplish is divided into the minimum unit of constructing with three-dimensional engineering model, and I is divided into object.The foundation of three-dimensional model can be used existing software PDS/Microstation to wait with the division of minimum construction unit to carry out.The construction unit can be regarded the set of a plurality of objects as; Simultaneously, according to the construction actual conditions of this project civil engineering, installation, the construction plan of establishment engineering; Set up the construction plan clauses and subclauses inventory (i.e. database) of engineering, be reflected in the database these plan clauses and subclauses corresponding information such as time.This construction schedule can be used existing software Primavera Project Planner (P3) to wait and formulate.
Utilization imports the 3D model that has been divided into each minimum construction unit through the three-dimensional browsing software SmartPlant Review (SPR) of applicant's secondary development.SmartPlantReview5.0 software is a visual software that is used for the large complicated three-dimensional model of interactive browse, be widely used in the heavy construction, but it does not possess the modification model, increases the plan associate field, thereby generates the function of 4D engineering model.The applicant has carried out secondary development to it, makes object and construction plan clauses and subclauses that it can related three-dimensional model, is able to set up the 4D engineering model.
Below; With combining Fig. 2 and Fig. 3 to be described in detail in through how object being increased attribute and according to the construction plan clauses and subclauses it carried out assignment among the SPR of secondary development; Thereby realize the related step of construction unit and construction plan; In Fig. 1, this step corresponding " related plan clauses and subclauses with 3D model construct unit ".
It is the process flow diagram that object increases attribute that Fig. 2 shows according to the embodiment of the invention.The new attribute of object increase to the 3D model is to accomplish through the database of 3D model is operated.This database comprises the labels table, label_names table, label_values table and linkage table or the like.Lables table is the summary table that has comprised each entry index of each object of three-dimensional model, and the delegation in this table has comprised these three of linkage_index (index of object names), label_name_index (the attribute-name index of this object) and label_value_index (the property value index of this object) at least; The title that has comprised attribute in the label_names table; The label_values table has comprised the value of attribute, and has comprised the value of indication three-dimensional model construction unit in the linkage table.
At first, in the labels of 3D model database table, select an object, the index label_name_index of this object of inquiry in lables shows, this index of inquiry is worth accordingly in the label_names table then, judges to be somebody's turn to do whether existence value sequence in the table.If do not have value sequence in the label_names table, then in this table, increase sequence, and return the label_name_index of this value sequence.If exist, then directly return the label_name_index of this value sequence.Through top step, added an attribute sequence just for an object of 3D model.Below, judge in the label_values table whether have the Noseq value, if do not have the Noseq value in the label_values table, then increase Noseq therein, and return the label_value_index of this value Noseq.If exist, then directly return the label_value_index of this value Noseq.Through top step, enclosed initial value Noseq just for an attribute sequence that object added of 3D model.Be reflected in the database, with regard to in the labels table being that the object of code name has increased attribute-name index label_name_index and property value index label_value_index with linkage_index.Each object is repeated top interpolation attribute sequence and the step of attaching initial value, up to accomplishing all objects.
Fig. 3 shows the process flow diagram of the value of attribute sequence being made amendment according to the embodiment of the invention.At first will import to through among the SPR of secondary development by the plan clauses and subclauses of construction schedule software P3 establishment; Be about to plan clauses and subclauses and copy among the p3taskname.txt under the SPR, make and when giving the attribute sequence assignment of object, from a drop-down list box, to select to plan clauses and subclauses.The user according to actual needs, the edit selection condition is screened a plurality of objects that needs are revised the value of attribute sequence according to this condition, the editor of this alternative condition can be realized by common alternative condition mode.Select the corresponding plan clauses and subclauses of these objects then, this selection step need be carried out artificial selection and accomplished from the drop-down list box of plan clauses and subclauses.Then, select an object in a plurality of objects that filter out from above and carry out the modification of Sequence value.In the linkage of database table, find the linkage_index of the object that is selected through DMRSLlinkage (value of representing object in the linkage table).According to this index, in the lable_names table, search the corresponding label_name_index of sequence, according to linkage_index and these two index of the label_name_index definite row that will revise in the labels table.In the label_values table, search the pairing index of selected entry values; Be label_value_index; Judge then whether the plan clauses and subclauses of choosing are arranged in this table; If do not have, then in the label_values table, increase the value of these plan clauses and subclauses of choosing, and return this 1abel_value_index.In the labels table, will be revised as the above-mentioned label_value_index that returns thus by the label_value_index of linkage_index and the determined row of label_name_index.To the step of each modification property value above object repetition, up to accomplishing all objects.
Like this; Accomplished to the increase of all objects attribute sequence in the three-dimensional model and according to the construction plan clauses and subclauses and accomplished modification property value; Through these steps; Object in the three-dimensional model and construction plan clauses and subclauses have been accomplished related because the property value that the construction unit uses comes from the plan clauses and subclauses, so can guarantee good association.
Return among Fig. 1; The construction plan clauses and subclauses related with the object of 3D model good after; SPR through secondary development classifies the object in the 3D model according to the value of its attribute sequence; And show successively according to property value time corresponding (according to time scale), to simulate engineering project and construction speed.
System notes the model picture of presentation process with picture format when the 3D model being carried out the progress demonstration.Through animation soft these pictures are organized, generated video file (the for example file of AVI form).
Play this video file, demonstrated the evolution process of the 3D model of this project along with construction speed, promptly visual 4D model has been realized the visualized management of schedule.
Can find out that the method that present embodiment is described has been utilized existing three-dimensional model and construction plan,, the two carried out association well, realize the making of four-dimensional engineering model simply, at low cost through Computer Interface Technology cleverly.
In the association process of schedule and 3D model or after having generated the 4D model; May find the corresponding construction unit of many schedules; By analysis; Find that it is reasonably that the schedule clauses and subclauses are divided, then be the to construct division of unit of its reason is thin inadequately, and reply 3D model is made amendment; Its construction unit is divided again; Meeting the requirement of logical relation of constructing, and then repeat above-mentioned associated steps, generate new 4D model; Also maybe be by analysis, discovery is because the schedule clauses and subclauses are meticulous, then need adjust the plan clauses and subclauses, and then repeat above-mentioned associated steps, generates new 4D model.In this process that schedule clauses and subclauses are readjusted, also be the process that the construction arrangement of reality is adjusted, have the effect of optimizing project construction.
In addition; Other that can also find that construction schedule possibly occur through visual 4D model are unreasonable; After for example generating the 4D model, find that these can come into plain view because unreasonable model object collision or the sequence of construction of causing of the front and back logical relation of schedule is unreasonable in visual 4D model; Can in time adjust as required the logical relation of schedule; To meet the construction technology logical order, avoided the unreasonable heavy losses that cause owing to schedule in the practice of construction stage, this also is another remarkable result of the present invention.
