Abstract
The invention provides a tower-type crane control system. The tower-type crane control system comprises a first camera arranged at a lower side of the top end of a long arm of a tower crane and second and third cameras respectively arranged at left and right sides of a high-altitude console. The three cameras respectively output image signals of a front arm and two sides of the tower crane to an image processing module. The image processing module transmits the image signals to three ground displays by corresponding first, second and third optical-fiber lines. The three ground displays comprise a first display for displaying tower crane front-arm images acquired by the first camera, a second display for displaying high-altitude console left-side images acquired by the second camera and a third display for displaying high-altitude console right-side images acquired by the third camera. The first display is centered and the second display and the third display are respectively arranged at the left and right sides. A ground console comprises the displays and a simulation operation platform.
