Background technology
Tower crane is that 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.
Portable tower tower crane and fixed type tower crane can be divided into by with or without traveling gear.
Portable tower tower crane can be divided into again rail mounted, rubber-tyred, truck mounted, crawler type four kinds according to the difference of running gear.Rail-mounted tower tower crane tower body is fixed on walking underframe, can run, good stability on ad hoc track, and can walk by on-load, work efficiency is high, is thus widely used in building installation engineering.Rubber-tyred, truck mounted and crawler-mounted tower tower crane rail-free device, conveniently moving, but can not on-load walking, less stable.
The tower tower crane of fixed type, according to the difference of installation position, is divided into again attachment jack up and inner climbing type two kinds, adheres to and can raise with building from the tower tower crane of liter and raise, be applicable to skyscraper, the horizontal load transmitted by tower crane is only born in building structure, convenient attachment, but it is many to take structural steel; Inner climbing crane tower is at interior of building (elevator, stair case), and climb by a set of bracket and elevator system, jacking is more loaded down with trivial details, but it is few to take structural steel, and do not need installing basis, 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 by elevator arrive top control between 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 high-altitude tower crane control method, achieves the Long-distance Control to high-order tower crane.
Technical scheme of the present invention is achieved in that
A kind of high-altitude tower crane control method, comprises the following steps:
On the downside of the long-armed top of tower crane and the overhead console left and right sides camera is set, export tower crane forearm and both sides picture signal to image processing module by described camera, picture signal is sent to the ground control cabinet built on ground by image processing module by optical fiber;
Build ground control cabinet on the ground, comprise telltale and simulation operations platform, simulation operations platform and practical operation platform 1:1 Mimetic design, simulation operations platform comprises sensor, by the action of sensor sensing operating personal;
By AD converter, the analog signal that sensor exports is converted to digital signal, the first controller is connected to described AD converter, actuating signal is transcoded into tower crane control signal;
By optical fiber, tower crane control signal is sent to tower crane top overhead console, overhead console comprises second controller and control box, receive tower crane control signal by second controller and decode, export decoded signal to control box, control box controls each electrical motor work of tower crane.
Alternatively, described controller is dsp processor.
Alternatively, described controller is TMS320F2812 dsp processor.
The invention has the beneficial effects as follows:
(1) camera by being arranged on multiple position realizes the multidimensional image collection of camp site, multiple read-out realizes construction scene and reduces in real time;
(2) build the simulation operations platform identical with actual platform on the ground, by the control box transmission instruction of network to tower crane top, control tower crane action, realize tower crane Long-distance Control.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the diagram of circuit of high-altitude of the present invention tower crane control method.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, high-altitude of the present invention tower crane control method, comprises the following steps:
Step (a), on the downside of the long-armed top of tower crane and the overhead console left and right sides camera is set, export tower crane forearm and both sides picture signal to image processing module by described camera, picture signal is sent to the ground control cabinet built on ground by image processing module by optical fiber;
Step (b), builds ground control cabinet on the ground, comprises telltale and simulation operations platform, simulation operations platform and practical operation platform 1:1 Mimetic design, and simulation operations platform comprises sensor, by the action of sensor sensing operating personal;
Step (c), is converted to digital signal by AD converter by the analog signal that sensor exports, and the first controller is connected to described AD converter, actuating signal is transcoded into tower crane control signal;
Step (d), by optical fiber, tower crane control signal is sent to tower crane top overhead console, overhead console comprises second controller and control box, receive tower crane control signal by second controller and decode, export decoded signal to control box, control box controls each electrical motor work of tower crane.
Preferably, described controller is dsp processor.
