Safety Monitoring for Dam Construction Crane System withSingle Frequency GPS Receiver

The construction site for large dam is very complex. Many huge construction cranes forms the key part for the construction. These huge cranes may move in some common working areas. The 3-dimensional movements of these machines are very complicated and the speed is relatively high. It’s very dangerous and disastrous if these machines collide each other with huge inertia. Therefore, dynamic and real time monitoring the movements of the machines and ensuring their safety running are very important.
