System for preventing collision of crane and monitoring of crane work

According to the present invention, a plurality of GPS receivers installed for each Golias crane, jib crane or tower crane, which acquire and transmit GPS coordinates for each crane; GPS coordinates of each crane received from the GPS receiver, the rotation angle and tilt information of the jib crane boom received from the tilt sensor and the first rotation sensor installed on the jib crane boom, and the second rotation sensor installed on the tower crane boom. Provided is a crane collision prevention and monitoring system including a main management unit for predicting collisions between cranes using rotation angle information of the tower crane boom, respectively. According to the crane collision prevention and monitoring system according to the present invention, by monitoring in real time not only the position of each crane but also the rotation angle and the inclination of the crane boom more accurately predict the collision between cranes and the risk of various accidents by real time notification of the collision risk And the resulting damages to human and physical property.
