Embodiment 1

[0100] Embodiment 1: After the two-dimensional model building unit establishes the two-dimensional model of the construction site, the coordinate value assignment unit takes a top angle of the two-dimensional model as the center to establish a plane Cartesian coordinate system, so that the entire two-dimensional model is located at the center of the plane Cartesian coordinate system. In the first quadrant, the coordinate values ​​assigned by the coordinate value assigning unit to the two-dimensional model are all positive, which is convenient for later analysis and calculation. The dangerous area division unit divides the dangerous areas in the two-dimensional model, and the coordinate value assigning unit assigns each The coordinate values ​​of the top corners are (10,10), (10,60), (60,10), (60,60);

[0101] The coordinate value assigning unit performs real-time positioning on the position of the construction personnel in the plane Cartesian coordinate system. The real-time po...

Embodiment 2

[0118] Embodiment two: the tower crane trajectory input unit is based on the two-dimensional model after the establishment and the plane Cartesian coordinate system, and inputs the trajectory coordinates in the tower crane operation process to form the tower crane operation trajectory coordinate value set Q={(M 1 , N 1 ),(M 2 , N 2 ),(M 3 , N 3 ),…,(M q , N q )}, where, q means that t is the time unit in the running track of the tower crane, and q coordinate values ​​have been experienced, and the dangerous area division unit is based on the coordinate value of the running track of the tower crane (M i , N i ) as the center of the circle, and R as the radius, establish the dangerous area on the running track of the tower crane, and the radius R is determined according to the following formula:

[0119]

[0120] Wherein, R=3 represents the distance between two adjacent coordinate values.

[0121] Tower crane construction time unit input tower crane construction time ...

Abstract

The invention discloses a building construction safety early warning protection system based on BIM, and belongs to the technical field of BIM building construction. An information input module is used for inputting various data information on a construction site into the system. A model establishing module is used for establishing a construction site model. A central control module is used for intelligently controlling the whole system. An analysis and early warning module is used for establishing a construction site model, and analyzing various dangerous behaviors in the construction process. According to the invention, a two-dimensional model and a rectangular plane coordinate system are established, according to a dangerous area dividing unit and a travel track prediction unit, the prediction of the advancing track of the construction personnel is effectively realized. Whether a constructor enters a dangerous area or not is judged according to the predicted advancing track, the face information of the constructor capable of entering the dangerous area for construction is determined according to the face recognition and face information input unit, irrelevant personnel can be effectively prevented from entering the dangerous area, and the personal safety of the constructor can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of BIM building construction, in particular to a BIM-based building construction safety early warning and protection system. Background technique [0002] Building Information Modeling is a new tool in architecture, engineering and civil engineering. It is used to describe those computer-aided designs that are based on three-dimensional graphics, object-oriented, and related to architecture; [0003] With the rapid development of the information age, the safety of building construction has also been transformed into information data for calculation and storage. The existing BIM building construction can only design and construct building models, but cannot guarantee the personal safety of construction workers. , has the following disadvantages: [0004] 1. During the construction process, the wearing of safety helmets for construction workers can only be worn by manual reminders. It is easy for construction...
