Visualization and supervision system of railway engineering construction process based on BIM technology

In the process of railway engineering construction, it is easy to appear great hidden trouble, and the management effect is poor, which can not solve the construction problem in real time. A visual supervision system for railway construction process based on BIM technology is designed. The Nano Pi 2Fire chip and GPS locator are designed in hardware. In the software, the visual data of railway construction is collected, the supervision database of railway construction is constructed based on BIM technology, and the visual supervision of railway construction is realized. Using the way of system test, the visual supervision effect is good, which can adapt to the construction supervision of railway engineering and is worth popularizing.
