Ped4Bim is a people flow and evacuation software which works closely together with BIM tools (Building Information Modeling) like Autodesk® Revit® or Allplan®. Ped4Bim can directly import different CAD/GIS/BIM formats like DXF, DWG, SVG, HPGL and CGM. Files in IFC format (Industry Foundation Classes) are converted into 2D layouts in advance via a web service. The simulation results are then read back into the BIM model in the form of density or load plots and displayed. Within the BIM workflow Ped4Bim can be used in different planning and construction phases as well as in later operation and maintenance phases.
This Autodesk® Revit® Add-in (DLL) is written in C# and is based on the .NET API of Revit®. It allows the export of individual floors from the 3D BIM model (Building Information Modeling) and saves them as a 2D floor plan in an XML file. This file can be imported by Ped4Bim and used as a layout for person simulation.
This project, realized with an Arduino Nano BLE, serves the wireless, multi-channel acquisition, management and analysis of sensor data. The output voltage of the angle sensors used in this case, are fed to the ADC inputs of the Arduino after signal processing, where they are averaged (low-pass) and sent at regular intervals via a Bluetooth module from uBlox to a computer. There the data can be received, saved and displayed both numerically and graphically. Stored data can be reloaded, shown and analyzed in more detail. The cleaned data is also used for the Trinamic Motion Control, which is later used to control the stepper motors.
