An embodiment of the present invention provides a BIM-based hazard source early warning method, please refer to fig. 1, where fig. 1 is a schematic flow chart of the BIM-based hazard source early warning method provided in the embodiment of the present invention, and the method includes:
and S11, acquiring a real-time BIM corresponding to the construction site.
In an optional embodiment, in the construction of the construction site, the real-time BIM model can be acquired based on the construction site, so that the linkage between the construction site and the real-time BIM model is realized, and the monitoring and management of the construction site are conveniently realized.
Optionally, the construction site may be a commercial building, a residential building, a stadium, or the like, which is not limited herein.
For components (such as precast slabs, beams, walls and the like) of a construction site, corresponding components are arranged in the real-time BIM, and the components are used for expressing the components of the construction site by setting different parameters (such as length, width, height, coordinates and other characteristic parameters).

For example, in a specific scenario, when a building needs to be built, a corresponding basic BIM model can be designed through BIM software, and the basic BIM model is used as a construction reference drawing, so that the building can be constructed according to the basic BIM model.
In other scenarios, the BIM model may also be updated according to a preset period, and for example, every other week or three days, the BIM model before updating may be used as the basic model.

In an alternative embodiment, corresponding second component information in the base BIM model may be looked up based on the identification of the first component information in the real-time site data. Specifically, the first component information may include information of a plurality of components (i.e., components), each component having a corresponding identifier, and the identifiers of the components are different whether the components are of the same type or different types. But the same or corresponding reference numbers are used for the same components.

Thus, for each component in the first component information, the corresponding component may be found in the base BIM model, and the second component information may then be updated with the first component information.
The method specifically comprises the following three conditions:
if a component in the first component information has a corresponding component in the second component information, but a parameter (such as a length and a width) of the component in the first component information is changed, the parameter of the corresponding component in the basic BIM model is changed by the synchronization.
If a member in the first member information does not have a corresponding member in the second member information, a new second member can be generated in the base BIM model based on the first member information in the second member information.
And thirdly, if a certain component in the first component information is deleted (namely the component is removed), the component is correspondingly deleted in the basic BIM model synchronously.
After the second component information is updated by using the first component information, the basic BIM model can be updated to the real-time BIM model.

In one embodiment, the member information includes hole information, and first, whether a hole corresponding to the hole information is covered with a grid may be determined based on the hole information, and if not, it may be further determined whether a shortest inner distance of the hole is greater than a preset threshold, where the shortest inner distance is an inner distance of the hole, and if the hole is a circle, the shortest inner distance is an inner diameter of the hole, and if the hole is a rectangle, the shortest inner distance is a length of a short side. If the shortest inner distance of the hole is greater than a preset threshold, indicating that the hole may cause the user to fall, the hole may be marked as a source of danger.
In another specific embodiment, the member information further includes boundary information, and then whether a space envelope or a wall is arranged on a boundary corresponding to the boundary information can be judged based on the boundary information; if not, marking the boundary as a danger source. That is, if the boundary has no corresponding enclosure or wall, it indicates that the boundary is unobstructed, that is, there may be a danger, and the boundary may be labeled as a danger source.
S123, generating a danger source area based on coordinate information of a danger source, wherein the danger source area comprises at least a first area and a second area, the first area is an area where the danger source is located, the second area is an annular area surrounding the first area, and the distance between the boundary of the second area and the danger source is larger than a preset distance threshold.

Optionally, the hazard source region specifically includes a first region and a second region, the first region is a region where the hazard source is located, for example, when the hazard source is a hole, the first region is a region where the hole is located, the second region is an annular region surrounding the first region, and a distance between a boundary of the second region and the hazard source is greater than a preset distance threshold.
In an alternative embodiment, the outer contour of the second area and the outer contour (border) of the first area are similar figures, i.e. enlarged by a predetermined factor compared to the first area, e.g. the first area is a circle, then the second area is also a circle. And the distance between the boundary of the second area and the hazard source is larger than a preset distance threshold value, so that the safety distance between the second area and the hazard source is ensured.
In other embodiments, the outline of the second region (boundary) can be a standard figure, such as a circle, a square, a rectangle, or other regular polygon, regardless of the shape of the outline of the first region.
