Definitions
- the invention relates to a method for controlling unmanned flying objects.
- gas and oil pipelines are used by train users and / or regular
- mountain subsidence areas are regions such as the northern Ruhr area, where intensive, ground-level mining has taken place, and now the soil gives way over a large area and slowly (but sometimes jerkily) and sinks.
- a pipeline lying in the ground is of course pulled along, it hangs in a row and can be damaged.
- Other ground movements can also lead to a compression of the line.
- Some pipeline operators therefore employ surveyors to continuously monitor such critical areas. If a certain amount is exceeded, the pipe must be dug up and cut through and then a corresponding piece inserted or cut out.
- drones used in the monitoring of gas and oil pipelines, but also of electrical cables from the air increasingly unmanned Flying objects. These are less expensive than the use of a helicopter, smaller and thus manoeuvrable and in an accident usually no people are at risk.
- flight altitude is often crucial in terms of data volume and data quality. Greater altitude provides an overview and reduces the risk of collisions with obstacles, which is particularly important for the automatic or semi-automatic flying of unmanned aerial vehicles based on predetermined routes.
- some of the sensors used in the surveying and inspection tasks benefit from the shortest possible recording or measuring distance, since the data quality decreases with the distance.
- an oblique view is required for inspection tasks, ideally in the flatest possible viewing angle.
- the invention is therefore based on the object of specifying a method for controlling unmanned aerial vehicles that meets these requirements.
- the invention enables the automated monitoring and measurement of equipment by autonomously flying unmanned Kliobj ekte.
- Fig. 1 shows the flow of Befliegung a storage area for detecting assemblies or components of inventories.
- Fig. 2 shows the flow of the Befliegung a high voltage power line.
- FIG 3 shows the survey survey of an aboveground pipeline mounted on uprights.
- Fig. 1 shows schematically a storage area BR with different components Bl, B2, B3, B4.
- This storage area may be located outdoors or in a closed space such as a garage. a warehouse.
- the components Bl, B2, B3, B4 can not only be located and identified, but also measured with high precision and checked for compliance with manufacturing tolerances, which often represents the condition for subsequent processing.
- the measurement accuracy of the altitude and, in particular, components Bl, B2, B3, B4 with a complex surface also depends on the recording angle and the number of measurement points, so that recordings or measuring operations from different positions are required for good measurement results.
- an unmanned flying object used for detecting and measuring objects in a storage area is now controlled in such a way that a largely obstacle-free overflight zone UZ is defined in advance for the area to be detected and measured, in which the unmanned flying object UAV Performs an overview of the storage area BR with suitable sensors and recording techniques.
- This obstacle-free overflow zone UZ is preferably provided at a height in which the highest expected objects Bl, B2, B3, B4 are flown over. If the storage area is roofed over, the overflow zone UZ will be provided below the roof or underneath roof-mounted elements, such as lighting fixtures.
- a first aerial survey and survey survey of the storage area BR takes place.
- an overview model of the storage area together with the objects contained therein is then determined.
- this is a three-dimensional digital surface model DOM, which for example by means of photogrammetric method from overlapping photographs with different positions, or by laser measurement (LiDAR) can be created.
- DOM three-dimensional digital surface model DOM
- a sequence of positions for detailed measurements and an obstacle-free flight route FR for an unmanned aerial model UAV for taking the sequence of positions is determined. This route is based on the control of the unmanned aerial model UAV.
- the measurement time which is particularly in applications in which the components Bl, B2, B3, B4 have only a short storage time, ie the lead time of the components through the camp is relatively low, represents a further significant advantage.
- the route FR can be optimized with known routing algorithms with respect to different parameters such as the time required, the energy consumption or the collision risk. Another preferred application of the method according to the invention will be explained with reference to FIG. 2.
- the illustration according to FIG. 2 shows the region around two electrical high-voltage lines HL designed as an overhead line. Due to its dimensions of many kilometers in length and a height of about 60 meters, the monitoring of these overhead lines is a task that is usually performed by helicopters.
- unmanned aerial vehicles UA can significantly reduce the cost of airborne flights, thus increasing the frequency of surveillance flights and increasing the quality of surveillance.
- the terrain in question is overflown in obstacle-free height and, for example, photographed or scanned by LiDAR.
- near infrared with a wavelength of 780 nm to 3 ym (spectral ranges IR-A and IR-B) is particularly well suited for the detection of vegetation, since in the near infrared range chlorophyll has a reflectivity about 6 times higher than in the visible spectrum. For the detection of vegetation, this effect can be exploited by taking a picture in the preferably red spectrum of the visible region, and a further recording in the near infrared.
- Utility buildings have approximately the same reflectivity in the visible as well as in the near infrared range, whereas chlorophyll-containing vegetation in the near infrared has a significantly higher reflectivity.
- z. B. green utility objects are distinguished by equally green vegetation.
- thermal infrared can be used to detect leaks in pipelines that contain liquids or gases with higher ambient temperature compared to the environment.
- the temperature of the conductors can be an indication of a defect and provide a thermal infrared image therefore valuable data.
- a three-dimensional digital surface model DOM is subsequently generated as an overview model.
- points of interests such as, for example, thermally conspicuous points or predefined fault-prone line elements, such as isolators, are determined and appropriate positions for detailed measurements are determined.
- the measuring method used and the resulting distances and angles to the object to be measured, as well as safety regulations must be taken into account so that on the one hand the quality of the determined data is optimum and, on the other hand, the probability of collision or endangerment of the unmanned aerial object UAV during takeoff and landing Position is a minimum.
- the electric field strengths and magnetic fields which possibly influence or disturb the measuring devices or the electronics of the unmanned flying object UAV must also be taken into account.
- the vegetation in the form of trees or shrubs forms obstacles and hazards for the aerial survey.
- a sequence of positions for detailed measurements and an obstacle-free flight route FR for an unmanned aerial model UAV for taking the sequence of positions is determined using known routing methods.
- the positions for detailed measurements may be determined by the geometry of the object.
- the unmanned flying objects UAV can also be equipped with different measuring devices.
- each unmanned aerial object UAV is assigned a specific section of a high-voltage pipeline SL.
- This assignment can also be made dynamically, for example as a function of the wind conditions and the respective ranges of the unmanned aerial objects UAV.
