Step (c), ground control cabinet comprises telltale and handles hand lever, handles hand lever and actual hand lever 1:1 Proportionality design, by handling hand lever inductive operation personnel's action;
Step (d), by being arranged on the travel switch in each action slot of handling hand lever, the position of inductive control hand lever, output switching signal;
Step (e), is converted to electric signal by the pressure sensor being connected with described manipulation hand lever by the pressure signal of handling hand lever; Described travel switch is complete corresponding setting with pressure sensor;
Step (f), is connected respectively to described pressure sensor and AD converter by electronic switch passage two ends, and its control end is connected to described travel switch;
Step (g), is connected to described AD converter by dsp processor, by pressure signal coding, by the first gateway, pressure code signal is transferred to the control box of a tower crane high position;
Step (h), described control box comprises the second gateway, receives described pressure code signal, PLC controller is controlled startup and the rotating speed of respective electrical motivation in motor unit according to described pressure signal.
Alternatively, described travel switch is photoelectricity correlation switch.
Alternatively, described controller is dsp processor.
Alternatively, described controller is TMS320F2812DSP treater.
The invention has the beneficial effects as follows:
(1) multidimensional image of realizing camp site by being arranged on the camera of a plurality of positions gathers, and realizes scene and reduce in real time on a plurality of read-outs;
(2) build on the ground the simulation operations platform identical with actual platform, the control box transmission instruction by gateway to tower crane top, controls tower crane action, realizes tower crane Long-distance Control.
