The quantity of chart display is three, the first telltale shows the tower crane forearm image of the first camera collection, second display shows the high-altitude control desk left-side images that second camera gathers, the 3rd telltale shows the high-altitude control desk image right of the 3rd camera collection, the first telltale is placed between two parties, and second display and the 3rd telltale are placed on respectively position, left and right;
Ground control cabinet comprises telltale and simulation operations platform, simulation operations platform and practical operation platform 1:1 copy design, simulation operations platform comprises sensor, move by sensor sensing operating personal, the analog signal of sensor output is converted to digital signal by AD converter, the first controller is connected to described AD converter, actuating signal is transcoded into tower crane control signal, and deliver to high-altitude, tower crane top control desk by optical fiber transmission, high-altitude control desk comprises second controller and control box, second controller receives tower crane control signal decoding, output decoded signal is to control box, the each electrical motor work of control box control tower crane.
Alternatively, described controller is dsp processor.
Alternatively, described controller is TMS320F2812 dsp processor.
The invention has the beneficial effects as follows:
(1) realize the multidimensional image collection of camp site by being arranged on the camera of multiple positions, on multiple read-outs, realize scene and reduce in real time;
(2) build on the ground the simulation operations platform identical with actual platform, send instruction by network to the control box at tower crane top, control tower crane action, realize tower crane Long-distance Control.
