A collision avoidance system for dam concrete construction based on GPS and GIS

It is necessary for dam concrete construction to take some measures to avoid large haulage equipment collision accident. A collision avoidance system based on GPS and GIS is established in order to reduce this accident with providing accurately monitoring and controlling in real time. In this paper, the function design of collision avoidance is detailed discussed, and the integrity of the system is verified through application used in Dagan Mountain dam concreting construction.
