Description

The invention relates to a flying drone comprising at least one data processing unit with a memory for optical assistance in construction projects and an associated method.

In building projects building material and / or components are usually spent according to a blueprint, building sketches or the like provided according to the blueprint bodies, for example, that at the intended place with stones, a wall is built or a floor slab is poured concrete.

Here is a well-known basic problem that a structure does not follow the blueprint or at least faulty, such as that a wall is built too long and thus a passage is too narrow. Furthermore, the sequence of the construction can lead to problems when technically a certain order is required and this is not adhered to in the execution. An example would be the laying of lines, in which lines that would be covered in the final state by other lines, preferably, of course, should be installed first.

There are no technical innovations to minimize these sources of error. The standard is still two-dimensional drawings, partly also in electronic form and then also shown in part three-dimensional, by means of which the construction staff by measuring and visual alignment with the site repeatedly during the construction process checks whether everything is provided in the right place and in the right order , However, this is extremely error prone.

Although remote-controlled aircraft drones are used in construction in the prior art, but not directed to the solution of this basic problem.

This is how the pamphlets show DE 10 2016 004 250 A1 and DE 10 20154 218 749 A1 the use of aircraft drones in construction projects, but only for the purpose of using a mounted on the drone camera to improve the field of view, for example, for the operator of a crane.

The corresponding drones each have sensors for their position determination and a corresponding feedback motion control, so that, for example, always the camera is directed to the goods transported by the crane and does not collide with the crane or other objects.

The publication DE 10 2016 004 250 A1 also discloses light generating means, which are used for transit time measurements for the purpose of position determination. This drone also stores construction site model data and / or blueprints to avoid collisions.

Although the better overview of the construction site by means of the cameras on the drones reduces the risk of collisions, it does not help much with regard to incorrect placement or the wrong sequence of building materials or components. Because it remains the case that the building staff must provide in appropriate knowledge of the blueprints by means of their own visual inspection of building materials and components in the right places in the correct order.

From the publication DE 10 2014 009 165 A1 For example, a technology is known according to which a camera drone picks up a building area from above, so that it is displayed in color on a screen after appropriate calculation or selection, in which area ideally a large manipulator, such as a crane, is to be placed, in order accordingly all desired locations be able to reach with the non-mobile large manipulator in use.

This thus helps to place the implement in an optimal location for construction, but still does not solve the problem of frequent errors in placement of building material and / or components.

The publication DE 20 2016 002 295 U1 also shows the use of a camera drone, but is concerned with the problem, as in the context of remote control of a crane the operator can be given appropriate feedback on deformations of the crane or the like.

Also, the use of drones for load transport in the context of construction activities is known, for example from the document DE 102 51 280 A1 ,

The problem of the correct order and placement of components and / or building material with only visual control by the construction staff based on the knowledge of the blueprints remains unresolved. However, this problem is becoming significantly more important due to the increasing complexity of the building technology and the cost minimization through appropriate prefabrication, as well as due to the now available thanks to available computing power possible detailed architectural planning for the purpose of space and space optimization.

As a result, this boils down to the fact that already calculated in detail during planning and It is determined where, which components or which building material of which size or quantity should be arranged, how exactly the lines for electricity, water and the like should run therein, etc.

This means, for example, that at a particular floor section, construction workers have to arrange elements such as steel grid support, piping for pipes, underfloor heating pipes, aqueducts, placeholders for openings and other elements in the right order at the right place, and then the whole structure with concrete or other Material must shed, whereby a total of the bottom element is formed. A placement error can cause the entire floor element to be replaced and rebuilt.

Furthermore, prefabricated components are used in which steel beams and gratings and concrete or the like are already connected to an element. At these and / or in these but then often still lines to place properly, holes properly positioned to drill and / or these are still to plaster, of course, only after z.b. Lines were placed correctly.

Similar problems also arise in wall and ceiling and roof elements, especially when using solar cells or solar thermal on the roof, because for solar cells / -thermy additional lines in wall and ceiling and roof elements are required.

The invention is therefore based on the object to minimize the error rate in the arrangement and construction of components and building material, especially in the case of complex and pre-planned wall, floor and ceiling elements.

This object is achieved by a flight drone according to claim 1, a construction support equipment according to claim 10 and by a method according to claim 11. Advantageous embodiments are the subject of the dependent claims.

The aircraft drone according to the invention is characterized in that it comprises an optical projection device which is designed to project optical patterns, and in that the data processing unit is designed to control the projection device in accordance with a blueprint provided in particular by the memory, to project a construction scheme as an optical pattern in which some work patterns correspond to positions of construction elements to be placed according to the construction plan and / or to building material to be placed.

For example, this could mean for the previously outlined case that the drone floats above the location at which the corresponding floor element is to be built. For example, positions of conduits that must be positioned before the supporting steel girder construction is placed and concrete poured are then projected.

As a result, the construction staff can immediately see visually where lines have to be laid before the steel grid is used and the concrete is poured. As a result, the risk is minimized that a line is forgotten and thus the floor element is built faulty and then expensive to correct or even replaced.

The same applies to prefabricated elements with existing steel girders / grids. In this case, if necessary, the lines must also be arranged in multiple layers without colliding with the steel girders / steel grid, in or through the finished element. Furthermore, the finished element must generally be plastered and the corresponding elements should be placed in the right places before plastering.

Furthermore, working time can be saved, since the next steps are always clearly visible, a review based on the blueprints is much less necessary and the work steps can be projected in an optimized order and thus done.

In addition, the requirements for the qualifications of the construction staff are lower, in particular with regard to skills for reading the building plans and transferring them to the concrete construction project.

Preferably, the data processing unit is further adapted to control the projection device to project as an optical pattern preferably provided in the memory positioning scheme in which some position patterns are designed according to the blueprint so that when the position pattern coincides with points or areas of a building area, the aircraft drone in a is for projecting the building structure on the construction area suitable position.

Basically, the projection of a building structure, which visually illustrates the construction staff at which point which element is to be placed, makes sense only if the drone or the camera is aligned in a suitable position and suitable.

A simple solution is the mentioned projection of a positioning scheme. This may simply consist of four points relative to the above-described example of the construction of a floor slab, in which, in accordance with the corresponding floor or wall elements defining the corners of the floor slab, it is immediately apparent to the building personnel that the projection apparatus and drone are properly aligned. to then subsequently or simultaneously project the building scheme for the use of the lines.

If the four points of the positioning scheme do not coincide with the intended corner points of the base plate, it is immediately apparent that the positioning of the drone and / or orientation of the projection device is not correct and accordingly a construction scheme projected by the drone, for example for the laying of lines, is not correct at present is positioned. Then, the position of the drone and / or orientation of the projection device can be corrected accordingly and / or the lines are positioned offset by the optically apparent shortfall offset to the working pattern, which comes into question when the vertices of the positioning scheme differ only slightly from the actual vertices of the bottom plate ,

Of course, a positioning scheme may be of a different nature than four points corresponding to the vertices of a floor slab to be built. Thus, for example, the edges of the future floor slab can be projected, which must then match corresponding with the floor or wall elements supporting structures. However, any other positioning scheme is conceivable in which the construction staff can visually recognize on the construction site whether the drone is correctly positioned. The choice of the positioning scheme depends on the subsequently or simultaneously to be projected Bauschemata and after the elements that were already placed in previous building steps, such as floor or wall elements supporting structures that are placed in front of floor or wall panels.

The latter is also the reason why the positioning schemes or the position patterns are to be selected according to the blueprint, because of these is indeed dependent on what is already built on the site, before the next step, which is supported by the projected building scheme should.

In the case of an already positioned prefabricated component, the use of the positioning scheme is particularly simple, because then the positioning scheme can be selected according to the finished element and the correct positioning of the positioning scheme is consistent with corresponding areas of the finished element, z.b. four corner points of the positioning scheme with the corners of the finished element. But also a positioning scheme for matching with other optically unique areas / parts of the finished element is conceivable. It is also conceivable to provide a marking on the finished element itself for compliance with the positioning scheme.

Preferably, the flying drone also comprises transmitting and / or receiving means for transmitting or receiving position signals which serve to determine the position of the aerial drone and / or alignment of the projection device, relative to a construction area. This can be done additionally or alternatively to the use of position schemes.

In particular, it is possible to place one or more position transmitters and / or position receivers at defined locations of the construction area which have been selected in accordance with the construction plan. The position of the drone and / or orientation of the projection device relative to the construction area can then be calculated automatically in accordance with the position signals received by the drone or according to the position signals received by the drone so that the drone is correctly aligned in the correct position and / or the projection device is to project the construction process that supports the next work step.

However, an existing positioning system, such as mobile phone masts or GPS, could also be used if this is sufficiently precise; In this case, a lack of precision of this positioning by signal can also be corrected or made verifiable by means of the aforementioned positional schemes.

The data processing unit of a corresponding drone with transmitting and / or receiving means for position signals is preferably designed to regularly move the drone according to the position signals, so that their position and / or the orientation of the projection device remains the same relative to the building area.

Such an automatic position correction is particularly useful with appropriate wind conditions and / or long work processes, since with time and / or due to a strong wind, the position of the drone can move and without automatic correction would have to be nachkorrigiert regularly by hand, so the drone and thus the structural design supporting the work process remains in the right place.

Preferably, a flight drone with corresponding transmitting and / or receiving means for position signals further comprises means for measuring transit time in order to determine the transit time of an emitted and / or received signal. Such a transit time measurement allows a high precision in the position determination by means of position signals.

Preferably, the projection device comprises a laser, since lasers are particularly suitable for projecting a construction scheme even at high altitude of the drone with sufficient resolution and sharpness. Furthermore, a laser is also more suitable for projecting corresponding construction patterns or working patterns through dust, fog or the like in sufficient strength. Especially dust often occurs on construction sites.

Preferably, the projection device or the flying drone is designed so that a projection direction of the projection device can be changed. Likewise, the projection device or the flying drone can be designed so that optical properties of the projection device or the projection can be changed, such as, for example, focal length, focus, sharpness, color intensity, etc.

Preferably, the projection device is designed to project optical patterns of different colors or multiple patterns of different colors simultaneously.

Thus, the corresponding colors can be used to encode order, element types or the like.

This would mean, for example, projecting the position of steel beams in one color while projecting the position of water pipes in another and the position of electrical wires or blanks therefor in a different color. Alternatively or additionally, the colors may also each still stand in which order elements or materials are to be arranged.

Or, in the case of prefabricated elements, in one color, the position of parts of the finished element could be projected as an alignment / positioning aid (e.g., the integral steel mesh / beams of the finished element), while in other colors, operations / positions to be performed on the finished element and / or or positions of it to be installed on or installed as conduits.

With a correspondingly clear specification by means of the construction plan and appropriately instructed construction personnel, it is thus possible to project the complex structure of a modern wall, floor or ceiling element at once. Then, for example, the first lines to be installed or placed are projected in red, while later to be placed elements such as covers are projected in green color at the same time. This makes it clear to the construction staff at all times which and how many elements are already positioned in the concrete floor slab to be built and which and how many elements are still missing and in which order the missing elements are to be built up or to be arranged.

Preferably, the projection device is designed to also project text, numbers and / or symbols. In this way, additional information can be projected, which causes a further reduction in the susceptibility to error. For example, indicating which component is to be built at this point, at which point of the site or the shell this is to take place, which elements / materials / order is associated with which color and the like.

Thus, for example, if in addition to the work patterns or the layouts of a base plate to be built is still textually projected that this floor plate, for example, on the second floor in the northeastern building corner is to minimize the risk that the corresponding floor panel on the first floor in the southwestern building corner is built.

In particular, the sequence and material can be coded by projecting the corresponding elements textually and / or numbered in their color of the working pattern. So for example, that in a free area of the bottom plate in red the lettering "1. Electrical cables "and in green the lettering" 2. Water pipe for floor heating "is projected, with a red working pattern of the Bauschemas indicates the places of here, for example, first to be placed electrical lines and a green working pattern of Bauschemas the places of the latter to be placed lines of floor heating. Equally, this is also possible for work steps and also in combination with elements, eg. "1. Drilling holes for water pipes "and" 2. Water pipes "for example in red and green. Of course, other colors are conceivable and / or another color coding of the order.

In addition to coding by means of colors, coding by patterns, hatching or other intensity fluctuations is also conceivable. Also, color changes, changing patterns or moving ones may be provided to encode something, e.g. an arrow that moves to a point where a specific element needs to be inserted.

Thus, in particular for the system accustomed personnel immediately and at every moment of the work process, the entire work process and what is still missing to almost complete with a single glance completely detectable, which in particular misalignments almost always immediately and in good time.

In principle, further information could also be projected, such as concrete work instructions or safety instructions, in particular also information that establishes a correlation or reference to the construction plans, for example a position or a page within a construction plan to which the construction scheme belongs.

A construction support equipment according to the invention comprises a flight drone according to the invention and a remote control for controlling the aerial drone, wherein the construction support equipment preferably further positioning elements such as markers, means for generating and / or reflecting optical signals or light, means for generating markers, mirrors, transmitter, receiver , Cameras and / or lamps, preferably each with means for positioning and / or fastening.

In this case, the other elements are selected in addition to the remote control, especially after what properties has the flight drone. For example, if positioning is only based on position patterns that are visually matched by construction personnel, markers such as pegs for impacting the ground and / or markers such as suitable pegs may be used. These then serve to have appropriate markings on the construction site, whose proper match with the projected position patterns indicates to the construction crew that the drone is in the correct position.

Mirrors are suitable for variants in which the position signals used by the drone are optical and the drone has, for example, a camera and / or light sensors. Then, the mirrors are placed in appropriate locations on the construction site, and upon reflection of the drone's position signals, usually just light, back to the drone in a suitable manner, the drone is correctly positioned. This may in particular also include an automatic feedback position feedback in the manner described above.

In addition to mirrors, other transmitters and / or receivers are also conceivable, for example transmitters for radio signals, which in turn are arranged in suitable positions on the construction site. A drone or its data processing unit equipped to receive corresponding signals can then determine the position of the drone, for example on the basis of the transit time and / or strength of the radio signals, wherein in turn automatic post-correction is conceivable.

Cameras and / or bulbs may also be provided to ensure the positioning of a suitably equipped drone. For example, the drone may have a light sensor or a camera, and with a correspondingly suitable detection of the bulbs positioned in the construction site, the correct positioning of the aerial drone is again ensured.

When using stationary cameras, for example, on the ground, the reverse is conceivable, namely that the drone has appropriate bulbs for position determination, the correct and appropriate detection by the stationary cameras ensures just the correct positioning of the drone. When using cameras, however, it is also possible to determine the position of drones without any separate means for determining the position when the camera image is checked electronically and the position of the drone within this image is determined.

The position of the drone can then be determined by several cameras on the construction site with the appropriate electronic determination of the drone.

With all these different variants for determining the position of the drone, it is basically possible to have both the entire required calculations for position determination carried out by the data processing unit of the drone and also by other systems not connected to the drone and, for example, located on the ground. A corresponding automatic position correction can then take place by transmission of the position by radio signals to the drone or by direct transmission of corresponding control commands to the drone.

For more complex or larger construction projects, the use of several drones is also conceivable at the same time. For this purpose, a drone according to the invention can also be equipped in each case with all those systems or properties which in the previous description have been referred to as elements which are located on the ground in order to enable relative positioning to other drones. For example, drones may have special color markers that capture other drones with cameras and determine their relative position to the other drone.

Positioning elements are preferably arranged stationary with respect to the construction site, preferably usually on the ground.

Such a relative positioning of the drones with each other can additionally reduce the risk of mispositioning, since then also incorrect position calculations / determinations of a drone will be noticed, because in general such a false position determination would result in an incorrect relative position to other properly positioned drones.

With several drones, it is also possible that some drones simultaneously project work patterns or building patterns in an overlapping area.

In principle, it is also technically possible to provide the projection device of the aircraft drone rotatable, movable and / or with optical elements that allow a change in the direction of projection, the focus or other optical properties to alternatively or additionally to the change of the projection location or target by means of Flight movement of the drone to effect a change of projection location or target. This can be technically advantageous if an obstacle is above a projection location and / or if the construction scheme is substantially or completely vertical, such as in the case of a wall element.

In principle, however, the projection device can also have a fixed orientation with respect to the drone and a corresponding change of the projection location or the projection direction is completely effected by a change in the position of the drone and / or the orientation of the drone.
