Abstract
The invention provides a tower crane ground control method. The method comprises the following steps: inducing the actions of operators by virtue of operating hand levers designed in a proportion of 1 to 1 with an actual hand lever; inducing the positions of the operating hand levers and outputting a switch signal by virtue of a travel switch arranged in an action groove of each operating hand lever; converting pressure signals of the operating hand levers into electrical signals by virtue of a pressure sensor connected with the operating hand levers; respectively connecting two ends of an electronic switch channel to the pressure sensor and an AD convertor, and connecting the control end of the electronic switch channel to the travel switch; encoding the pressure signals by connecting a DSP processor to the AD convertor; through a first gateway, transmitting the encoded pressure signals to a control box at the high position of a tower crane; through a second gateway of the control box, receiving the encoded pressure signals; controlling the start and rotation speed of a corresponding electromotor in an electromotor group by a PLC according to the pressure signals.
Description
Technical field
The present invention relates to automation field, refer to especially a kind of tower crane ground controlled approach.
Background technology
Tower crane is a kind of weight-lifting equipment the most frequently used on building ground, has another name called tower crane, with a section spreading, is used for hanging the raw MAT'L of the constructions such as working reinforcing bar, wood are stupefied, cement concrete, steel pipe.
By having or not traveling gear can be divided into portable tower tower crane and fixed type tower crane.
Portable tower tower crane can be divided into again four kinds of rail mounteds, rubber-tyred, truck mounted, crawler type according to the difference of running gear.The tower tower crane tower body of rail mounted is fixed on walking underframe, can on ad hoc track, move, and good stability, can walk by on-load, and work efficiency is high, thereby is widely used in building installation engineering.The tower tower crane rail-free of rubber-tyred, truck mounted and crawler type device, conveniently moving, but can not on-load walking, less stable.
The tower tower crane of fixed type is according to the difference of installation position, is divided into again and adheres to two kinds of jack up and inner climbing types, adheres to from rising tower tower crane and can raise with building, be applicable to skyscraper, the horizontal load being transmitted by tower crane is only born in building structure, convenient attachment, but it is many to take structural steel; Inner climbing crane tower, at interior of building (elevator, stair case), climbs by a set of bracket and elevator system, and jacking is more loaded down with trivial details, but it is few to take structural steel, does not need installing basis, and all deadweight and load are born by building.
No matter be movable tower crane or fixed type tower crane, all need operating personal voluntarily or arrive by elevator between the control at top and operate, stand the working environment of high temperature and heating summer or low temperature severe cold, and tower crane is higher, danger coefficient is also higher, and tower crane accident also happens occasionally, therefore, how realizing the Long-distance Control of high-order tower crane, is current problem demanding prompt solution.
Summary of the invention
The present invention proposes a kind of tower crane ground controlled approach, has realized the Long-distance Control to high-order tower crane.
Technical scheme of the present invention is achieved in that
A kind of tower crane ground controlled approach, comprises the following steps:
Step (a), by with the manipulation hand lever of actual hand lever 1:1 Proportionality design, inductive operation personnel's action;
Step (b), by being arranged on the travel switch in the action slot of each manipulation hand lever, the position of inductive control hand lever, output switching signal;
Step (c), by the pressure sensor being connected with described manipulation hand lever, is converted to electric signal by the pressure signal of handling hand lever;
Step (d), 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 (e), is connected to described AD converter by dsp processor, and pressure signal is encoded;
Step (f), by the first gateway, is transferred to pressure code signal the control box of a tower crane high position;
Step (g), by the second gateway of described control box, receives described pressure code signal;
Step (h), by PLC controller according to startup and the rotating speed of respective electrical motivation in described pressure signal control motor unit.
Alternatively, described travel switch is complete corresponding setting with pressure sensor.
Alternatively, described dsp processor is TMS320F2812 dsp processor.
The invention has the beneficial effects as follows:
Build on the ground the simulation operations platform identical with actual platform, send instruction by gateway to the control box at tower crane top, control tower crane action, realize tower crane Long-distance Control.
Brief description of the drawings
