Example 1:
referring to fig. 1, the invention discloses a Building Information Modeling (BIM) -based stair surface clearance inspection system, which comprises:
the building module 1 receives a civil model input from the outside by using Revit software, and the BIM technology can build a building information model according to the civil model, store and output the building information model.
And the screening module 2 is used for responding to the building information model, picking up all information marked as the floor in the building information model to form a comparison information group, picking up information of the stair surface layer in the building information model to form an analysis information group, and outputting the comparison information group and the analysis information group.

And the threshold setting module 6 is used for responding to the distance data set, calling a preset range value, generating threshold data and outputting the threshold data set by taking the data in the distance data set as a basis and the range value as a boundary.
The essence of the threshold data is that the result of the allowable error set by the operator is added on the basis of the calculation result, namely the maximum error which can be allowed during construction, and the operator can compare the actual distance with the threshold data during construction to judge whether the construction is qualified.
The comparison module 7 receives actual value data input from the outside, responds to the threshold value data set, compares the actual value data with the threshold value data, judges whether the actual value data meets requirements or not, judges whether the actual value data falls in the threshold value data range according to a judgment standard, picks up the actual value data meeting the judgment standard to generate a qualified data set, picks up the actual value data not meeting the judgment standard to generate an abnormal data set, and outputs the qualified data set and the abnormal data set.
And the alarm module responds to the qualified data set and the abnormal data set, stores the qualified data set and outputs the abnormal data set.
Data in the qualified data set is that the distance between the stair surface layer and the floor slab is within the maximum error range during actual construction, and only the data need be stored and recorded, the data in the abnormal data set represents that the actual value of construction is greater than the maximum allowable error, and the alarm module can give an alarm to constructors for the data, and reminds the operators to carry out secondary processing on the stair surface layers.
And the recording module 9 receives actual value data input from the outside, responds to the distance data group, stores the actual value data and the distance data which correspond to each other, and supports the output of the actual value data and the distance data.
The recording module 9 allows an operator to call corresponding actual value data and distance data group data for comparison when sampling inspection or adjustment is performed on the system, so that data acquisition when the operator debugs the system is facilitated.
