Embodiment 1
[0049] see Figure 1-Figure 4 As shown, this embodiment provides a BIM-based engineering construction schedule management system, including a schedule compilation unit 100, a BIM schedule tracking unit 200, and a model comparison unit 300;
[0050] The progress plan preparation unit 100 is used for pre-designing the project construction plan, and preparing the three-dimensional model diagram of the project construction plan;
[0051] In this embodiment, the schedule preparation unit 100 includes a construction scheme setting module, a model preparation module and a construction material recording module;
[0052] The construction plan setting module is used to design the construction plan of the engineering construction;
[0053] The model compilation module is used to construct the renderings according to the construction plan, and generate the three-dimensional model diagram of the plan, so as to facilitate a more intuitive understanding of the construction plan;
[0054] ...
Embodiment 2
[0082] Considering that when the project construction exceeds the expected plan, the materials and construction period cannot be updated in time, which will affect the subsequent normal construction progress. The difference between this embodiment and Embodiment 1 is that:
[0083] The schedule preparation unit 100 also includes a plan optimization module, the plan optimization module is used to receive the signal reminding the staff from the remote interaction module, and adjust the content of the remote interaction module according to the on-site three-dimensional model;
[0084]The plan optimization module can realize the modification of the content recorded in the construction material recording module, and use Transact-SQL statements such as INSERT, DELETE and UPDATE to add, delete or change information in the database of the construction material recording module, so that according to the actual project The construction is carried out to adjust the construction materials,...
Embodiment 3
[0087] Considering that the data scanned by the 3D laser scanner is redundant and takes up a large space, resulting in unsmooth modeling, which is not conducive to the accuracy of the modeling of the model building module, so cloud processing is performed before the model is built. This embodiment and implementation Example 1 differs in that:
[0088] The model building model also includes cloud processing redundancy elimination algorithm, including the following steps:
[0089] Point cloud splicing, unifies the coordinates of the data points scanned by the 3D laser scanner, takes the scanning station as the benchmark, and unifies the scanned images of other stations into the coordinate system of the reference station through the forced addition of points with the same name;
[0090] Data redundancy is used to uniformly identify building characteristic range values through data point coordinates, reduce the amount of data points on the basis of maintaining model accuracy, an...
