PURPOSE: A crane collision prevention system using a hybrid collision detecting technique is provided to accurate predict the collision between cranes since the position of each crane, the rotating angle and the slope of a crane boom are monitored in real time. CONSTITUTION: A crane collision prevention system obtains the GPS coordinate of a crane using one or more GPS receivers(110) on the crane, transfers the obtained GPS coordinate information to a main manager(200), collision signal information are transferred from the crane, moved objects(40) and a collision sensor(150) on a fixed obstacle(50) on a working field to the main manager. The main manager predicts the collision possibility of the cranes on the working field based on the GPS coordinate information and the collision signal information through a communications network comprising a communication unit. |
