Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] Embodiment 1

[0062] Among them, the CIM data platform includes the currently completed building data, namely the built data, wherein the built data is the built building size data and the coordinate point data of the built building;

[0063] First, a horizontal plane coordinate system is constructed in the CIM platform with the center point of the first building model under construction as the coordinate origin; wherein the horizontal plane coordinate system is constructed based on the horizontal plane in the CIM data platform;

[0064] Randomly select n edge points of the BIM building model under construction, and obtain the distance values ​​from the n edge points to any two adjacent feature points of the completed buildings; where n≥2, when determining the location of the BIM building model under construction, the location of the model can be determined by locating the two edge points; the more edge points there are, the more accurate the location of the BIM building model under construction;

[0065] It should be noted that the built building feature points are special points on the built building, such as the endpoints of the built building;

[0066] Therefore, the position of the BIM under-construction building model can be realized based on the distance between any two or more edge points and adjacent feature points of the built model;

[0067] Then, based on the distance value between the edge point of the BIM building under construction and the feature point of the completed building, the edge point of the BIM building under construction model is located; thus, the relative position of the BIM building under construction model between other completed building models in the CIM platform can be confirmed;

[0071] At the same time, based on the vertex coordinates, the model coordinate length value MLz and the model coordinate width value MKz of the BIM building under construction in the CIM data platform are calculated;

[0072] Then, the plane length deviation value lcp of the BIM building model under construction is calculated by lcp=|MLz-LZ|;

[0073] Then, the plane width deviation value kcp of the BIM building model under construction is calculated by kcp=|MKz-KZ|;

[0074] Then, based on the BIM building model under construction and the horizontal plane in the CIM data platform, the vertex angle value on the horizontal plane of the building under construction is marked as ω i ; Where i is 1, 2, 3, ...;

[0076] Compare the plane qualified characterization value Pass with the model deviation threshold Pmax;

[0077] If the plane qualified representation value Pass is less than or equal to the model deviation threshold Pmax; a BIM model positioning qualified signal is obtained;

[0078] If the plane qualified representation value Pass is greater than the model deviation threshold Pmax, a BIM model positioning deviation signal is obtained, and the BIM building model under construction needs to be repositioned;

[0079] By verifying and calculating the size data of the BIM building model under construction in the CIM platform, the data matching positioning deviation of the BIM building model under construction can be measured to ensure the accuracy of the BIM building model under construction in the CIM platform, so as to ensure the accuracy of data calculation during the inspection process of the inspection batch;

[0080] Construction inspection module: obtains the construction inspection batch and BIM model data, and inspects the buildings under construction in the inspection batch;

[0085] pass Calculate the construction height progress deviation rate Hcp at construction time t t ;

[0086] Determine the construction height progress deviation rate Hcp at construction time t t Is it greater than zero?

[0087] If the construction height progress deviation rate Hcp t If it is greater than or equal to zero, a qualified construction progress signal is generated;

[0088] If the construction height progress Hcp t If it is less than zero, a slow construction progress signal is generated; at this time, the construction process should be reminded to ensure that the construction is completed on time;

[0089] With the construction progress qualified signal, through CNL t =a×HZ t + b Calculate the expected progress rate CNL of materials used in the BIM building model at time t within the construction cycle time value T t ; Among them, a is the material coefficient of the building height, and b is the correction value of the building height impact;

[0090] Get the actual progress rate CL of materials used in the BIM building model under construction at time t within the construction cycle time value T t ;

[0091] Then through Calculate the construction material progress deviation rate Ccp at construction time t t ;

[0094] If the progress material is stable value ylh t If it is less than or equal to the progress material deviation value Jhy, a qualified signal for construction materials will be generated, and subsequent construction can continue;

[0095] If the progress material is stable value ylh t If the value is greater than or equal to the progress material deviation value Jhy, an abnormal signal of construction materials is generated, indicating that there are deviations in building height and construction materials during the construction process. At this time, it is necessary to measure and calculate the construction building or construction materials to ensure that the building reaches the safety and stability standards at the time t.

[0096] Inspection and positioning module: Based on the slow construction progress signal or abnormal construction material signal obtained by the construction building inspection in the inspection batch, the BIM under-construction building model corresponding to the construction building is obtained, and then the coordinate point data of the BIM under-construction building model in the CIM data platform is obtained, so as to obtain the positioning under the slow construction progress signal or abnormal construction material signal in the inspection batch.

[0097] Combining the BIM model with the CIM platform, locating the coordinate points of the BIM model in the CIM platform, ensuring the accuracy of the coordinate points of the BIM model, can better ensure the positioning accuracy of the inspection batch during inspection;

[0098] By inspecting the inspection batches, quality problems in the production process can be discovered and corrected in a timely manner to ensure that the project quality meets the standards. Random inspections of construction buildings within the inspection batch can reduce the number of inspections and inspection time, improve inspection efficiency, and build models of buildings through the BIM model and conduct inspections of inspection batches to ensure the standardization and uniformity of construction buildings, facilitating unified management and control of project quality.
