Technical Field
The invention relates to the technical field of fire fighting, in particular to a BIM-based fire fighting drill method.
Background
The BIM (building Information modeling) technology is firstly proposed by Autodesk company in 2002, has been widely recognized in the world, can help to realize the integration of building Information, and all kinds of Information are always integrated in a three-dimensional model Information database from the design, construction and operation of a building to the end of the whole life cycle of the building, and personnel of design teams, construction units, facility operation departments, owners and the like can perform cooperative work based on the BIM, thereby effectively improving the working efficiency, saving resources, reducing the cost and realizing sustainable development. The core of BIM is to provide a complete building engineering information base consistent with the actual situation for a virtual building engineering three-dimensional model by establishing the model and utilizing the digital technology. The information base not only contains geometrical information, professional attributes and state information describing building components, but also contains state information of non-component objects (such as space and motion behaviors). By means of the three-dimensional model containing the construction engineering information, the information integration degree of the construction engineering is greatly improved, and therefore a platform for engineering information exchange and sharing is provided for related interest parties of the construction engineering project. BIM has the following characteristics: the method can be applied to design and can also be applied to the whole life cycle of construction engineering projects; the design by BIM belongs to digital design; the BIM database is dynamically changed and is continuously updated, enriched and enriched in the application process; and a collaborative platform is provided for all parties participating in the project. In the research and development of the BIM standard in China, a research group has already obtained staged results.
In recent years, the field of BIM application is increasing, but the application to the field of fire drill has not been substantially developed, and building information of buildings is collected by using the BIM, and then a fire prevention and execution scheme is designed, so that an important way for executing an actual operation scheme of an actual fire site is provided.
