Abstract
The invention provides a multidimensional acquisition system for a construction site. The system comprises a first camera, a second camera and a third camera, wherein the first camera is arranged at the lower side of the top end of a long arm of a tower crane; the second camera and the third camera are respectively arranged at the left side and the right side of a high-altitude control console; the three cameras are respectively used for outputting the image signals of a front arm and the two sides of the tower crane to a first image processing module, a second image processing module and a third image processing module; the image processing modules are used for transmitting image signals to a ground display device by a first optical fiber circuit, a second optical fiber circuit and a third optical fiber circuit correspondingly.
Description
Technical field
The present invention relates to automation field, refer to especially a kind of camp site multidimensional acquisition system.
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.
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 camp site multidimensional acquisition system, has realized the remote image collection to high-order tower crane.
Technical scheme of the present invention is achieved in that
A kind of camp site multidimensional acquisition system, comprise: be arranged on the first camera of the long-armed top of tower crane downside and be arranged on second camera and the 3rd camera of the control desk left and right sides, high-altitude, above-mentioned three cameras are exported respectively tower crane forearm and both sides picture signal to the first image processing module, the second image processing module and the 3rd image processing module, and described image processing module is sent to picture signal at chart display by corresponding the first fibre circuit, the second fibre circuit and the 3rd fibre circuit;
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.
Alternatively, described image processing module is dsp processor.
Alternatively, described image processing module is TMS320F2812DSP treater.
The invention has the beneficial effects as follows:
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.
Brief description of the drawings
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the control block diagram of camp site of the present invention multidimensional acquisition system.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, camp site of the present invention multidimensional acquisition system comprises: the first camera 10 that is arranged on the long-armed top of tower crane downside, and be arranged on second camera 11 and the 3rd camera 12 of the control desk left and right sides, high-altitude, above-mentioned three cameras are exported respectively tower crane forearm and both sides picture signal to the first image processing module 20, the second image processing module 21 and the 3rd image processing module 22, described image processing module is by corresponding the first fibre circuit 30, the second fibre circuit 31 and the 3rd fibre circuit 32 are sent to picture signal at chart display, article three, fibre circuit twisted wire is wound around.
The quantity of chart display is three, the first telltale 40 shows the tower crane forearm image of the first camera collection, second display 41 shows the high-altitude control desk left-side images that second camera gathers, the 3rd telltale 42 shows the high-altitude control desk image right of the 3rd camera collection, the first telltale 40 is placed between two parties, and second display 41 and the 3rd telltale 42 are placed on respectively position, left and right.
Preferably, described image processing module is dsp processor.
Preferably, described image processing module is TMS320F2812DSP treater.Realize the transcoding of signal by TMS320F2812DSP treater, transmit in real time tower crane picture signal.
TMS320F2812DSP, is 32 fixed DSPs, and the AD data acquisition that it has EVA, EVB task manager and supporting 12 16 passages, has abundant Peripheral Interface, as CAN, SCI etc.The ADC module of TMS320F2812 is 12 bit resolutions, has the A and D converter of pipeline organization, the built-in dual-sampling hold circuit of TMS320F2812, and while keeping data acquisition, window has independently pre-calibration to control.And permission system is to same Channel-shifted repeatedly, allow user to carry out over-sampling algorithm, this more traditional single transformation result has increased more solution, is conducive to improve the precision of sampling.There are multiple trigger sources can start ADC conversion.Fast speed transfer time, ADC clock can be configured to 25MHz, and the highest sampling bandwidth is 12.5MSPS.While building data acquisition system with TMS320F2812, needn't external ADC, avoid complicated hardware design.
