JP7042238B2 - Configuration and method for inspecting objects, especially buildings - Google Patents

Description

The invention relates to a configuration and a method for inspecting an object, particularly a building, according to an introductory part of an independent claim.

Buildings require regular and detailed inspections by qualified professional inspectors to detect the condition of the building. This is true for many other objects as well. The test may provide information, for example, whether the structural integrity of the object is guaranteed. Buildings, especially buildings, warehouses, bridges, towers, tunnels, roads and shelters, need to be inspected regularly to ensure adequate suitability and load-bearing safety for use. Inspections are carried out at the time of manufacture and use, with diversion and possible withdrawal of the building.

Such tests may have to consider a large number of data and parameters. As an example, when inspecting a building, it is possible to consider the material properties of the part, operating parameters, specifications and recommendations from possible standards and guidelines, as well as specific requirements consisting of the part in the context of the entire building, for example. is necessary. Therefore, it is necessary to provide an inspection system that can integrate a large number of data as high as possible and make the data available to professional inspectors in an obvious manner.

Building inspection typically involves a comprehensive survey of the building in which inspection-related conditions such as defects and / or failures in the building or individual parts are visually identified and detected. Hereinafter, defects will be described as an example without limiting the generality of inspection-related situations. Professional inspectors analyze these defects in further steps and, based on them, derive, for example, a diagnosis of defect type or defect topology. Diagnosis is seen, for example, as the basis for making further inspection steps and / or decisions on measures to eliminate defects. This carries the risk that defects and their potential impact on the building will be overlooked and / or inaccurately assessed by professional inspectors.

Defect registration usually involves entering defects into a diagram by a professional inspector at the time of inspection, for example a building construction plan. The registered defects are then generally detected electronically and entered into a database, for example, or in a CAD-based construction plan for the building, or for example, a building made using an essentially known 3D scanner. Included in the model of. This procedure has the disadvantage, first of all, that the detection of defects depends solely on the perception and attention of the professional inspector. However, defect detection forms the basis of all further measures and should have increased redundancy, for example, which can reduce the risk of erroneous input or undiscovered defects. Second, transferring graphically detected defects to electronic data acquisition carries the risk of transfer errors, for example as a result of incorrect numerical input. Moreover, thus, it is not possible to later track where the error occurred during the inspection. In addition, repeated transfer of data is inefficient and requires a great deal of effort. As an example, it is not possible to track whether a defect was actually detected by a professional inspector or was lost only afterwards, for example during data transfer.

An integrated system that attempts to overcome at least some of the existing disadvantages is described in US Pat. No. 6,725,097. The system allows visually recognizable defects to be input to a mobile input device carried by a professional inspector during inspection. Defects can, for example, be categorized based on their visible structure according to default choices and depicted on the construction plan. In this case, the defect can be manually drawn in the construction plan, for example using a graphical input program, or photographed on site. The input device may further include a programmed algorithm for analyzing the input defect.

This system has improved interactivity and data integration, but as with previous systems, inspection data detection is performed only by professional inspectors, so it has no or low redundancy. As a result, advantageously automated defect analysis is also based solely on the detected defects, i.e., the perception and attention of the expert inspector at the time of their detection. This system does not provide protection against defects that were missed during inspection, nor can it be later determined whether the defect was missed or did not occur until after detection.

Therefore, the task addressed by the invention is to overcome the disadvantages of the prior art. In particular, the challenges addressed by the invention are broadly applicable configurations and widely applicable methods for inspecting objects, especially buildings, that enable reliable detection of real-world and even structural defects. Is to provide. In addition, the configurations and methods are intended to be convenient to operate and implement, and to ensure a high degree of safety. In addition, the configurations and methods are intended to ensure that it is possible to later track where inspection-related conditions were detected on the object, especially on the building.

These issues are solved by configurations and methods that have the characteristics of independent claims.

An independent claim comprises a mobile measuring unit for inspecting an object, in particular a building, for identifying a measurement assigned to the object in the first aspect, wherein the measuring unit is: It relates to a configuration having an interface for exchanging data with additional units of the configuration, particularly the base unit. Further, the configuration specifically includes a mobile base unit, in which the data set communicated by the measurement unit can be stored and preferably visually represented, the base unit being configured. It has an interface for exchanging data with additional units, especially at least mobile measurement units. Preferably, the base unit further has an interface for exchanging data with a proprietary or public network. The configuration further includes detection means for detecting the measurement position where the measured value is specified and / or for detecting the measurement time when the measured value is specified. In this case, the measured value identified by the measuring unit is preferably able to communicate to the base unit as a data set, preferably automatically, with at least the measured position detected by the detection means. In this case, the mobile measurement unit is designed to non-destructively identify measurements with respect to the internal structure and / or internal state of particularly inaccessible elements of the object, especially parts of the building. The identification of the measured values may be performed, for example, by a field user operating the measuring unit. In this case, the on-site user refers to a user who is present at the location of the object at the time of inspection, for example, a specialized inspector who is entrusted with the inspection. Alternatively, the measuring unit may be further designed to be remotely controllable, eg, via a base unit.

Here and below, building is understood to mean a structure built by humans that is in static contact with the foundation. A building can be, for example, a human dwelling, an animal containment facility, a plant growing facility, or, for example, a building that is useful for storing items or operating machinery. The building can further be a transportation structure such as a bridge, road, tunnel or corridor. Alternatively, the structure may further include, for example, wells, water pipes and / or sewage pipes, sewage treatment plants, embankments, reservoir dams, masonry dams, dams, chimneys, towers (eg wind towers or transmission towers), transmission masts or fictitious transmissions. It can be a supply and / or waste structure, such as a wire tower. In addition, the structure can be a security structure, such as a nuclear power plant or security well, a security dam, a system for distributing avalanches, a road shield or shelter. The structure can further be a weir facility and / or a fortress facility, such as a fortress or a fortress tower. In addition, the term "building" includes mines and open pit mines, as well as temporary structures such as temporary structures, tents, trade fair exhibition halls, auxiliary structures, container structures and storage.

In addition to buildings, the term "object" as used herein and below refers, for example, to devices, machines, vehicles, aircraft, furniture, works of art (eg, the truth of which is the composition and / or invention of the invention. It also includes, for example, movable objects, such as (which can be confirmed using such methods), but also organisms such as plants, animals or humans.

Here and below, "internal structure" and "internal state" refer to the respective states of structures and objects that are purely visually unrecognizable, as is possible, for example, with the naked eye or with a camera. It is understood to mean. The terms "internal structure" and "internal state" therefore include, on the other hand, the internal structure and state of the object. However, they also include structures and states that are actually present on the surface of an object that is essentially visible to the user, or within areas of such a surface, but are purely visually unrecognizable. As an example, in the context of the invention, the elasticity of an object in the region of the visible surface is also considered an internal state because such elasticity is purely unrecognizable.

The base unit and / or measurement unit preferably include means for storing, processing, inputting and outputting, and receiving and communicating data. There may be storage and compute units for storing and processing data. In particular, the base unit may be designed so that data structures, programs, datasets (original and / or derived datasets) and / or instructions, also described in more detail below, can be stored on the base unit.

Means for input may include, for example, a touch-sensitive area and / or a keypad and / or a microphone. For example, a diagram may be registered by the user via the touch-sensitive area. The keypad allows the user to enter text containing numbers. Voice input can be performed via a microphone. These data thus entered are then communicated to the base unit as a dataset, along with the relevant measurements identified by the measurement unit and the associated measurement position and / or measurement time detected by the detection means. There it can be stored and / or processed at will. Thus, there may be some sort of logbook that can be used to record which user performed which measurement at what time, where, how, and for what.

The means for output may include, for example, a printer, through which, for example, a measurement log may be output. However, the means for output are preferably designed so that object-specific, especially building-specific data or data structures can be visually represented. Combined means for input and output may be provided, for example, by a touch-sensitive screen.

As a visual representation, a particularly three-dimensional virtual model of the object to be inspected may be visually representable to the user in the field on the base unit and / or the measurement unit. Assuming a preferred means of input, field users can interact with the virtual model where appropriate, for example, selecting a view or marking a measurement position. Instructions to the field user, such as a measurement command to the field user, for example indicating the measurement position and / or the measurement time and / or the type of measurement, may be expressed as well.

In certain embodiments, the configuration may only include a single base unit. As a result, it is possible to reduce the expenditure on the device side. However, the configuration may further include multiple base units, especially for the inspection of relatively large and / or relatively complex objects. Then, each of the base units may have an interface for exchanging data with each other.

The measuring unit is advantageously designed so that the user in the field can carry the measuring unit. In particular, the measuring unit may be correspondingly dimensioned and have a corresponding weight for this purpose. Alternatively, the measuring unit may, for example, be positioned or may be positioned specifically in or on a vehicle that is remotely controllable.

The base unit is preferably accessible by a user in the field, for example, inside an object, especially inside a building, or specifically built outside an object, such as inside or on a vehicle. Designed as a mobile unit that can be positioned outside an object. The base unit is advantageously designed so that the user can carry the base unit. In particular, the base unit may be correspondingly dimensioned and have a corresponding weight for this purpose. Preferably, the base unit is implemented, for example, in a carrying case or in the form of a laptop or tablet computer. The base unit preferably has a protective housing that provides protection from mechanical damage, for example in a hazardous environment at a construction site. Alternatively, the base unit may, for example, be positioned or may be positioned specifically in or on a vehicle that is remotely controllable. However, in principle, the base unit can also be further configured, for example, as a maintenance or inspection terminal fixed on an object, especially on a building.

The base unit may have an interface for exchanging data with a wired or wireless, proprietary or public external network. In this way, the base unit can be linked to a local (eg, server unit) or non-local (so-called "cloud") network service unit. Correspondingly, data can be communicated to or obtained from the network service unit, especially in real time. As an example, the Internet (public) or mobile wireless network (proprietary) can be used as an external network.

The base unit itself can be designed as a server or can include a server, which is within the scope of the present invention. Data exchange between the interface of the measurement unit and the server can be performed via proprietary or public network. In this embodiment, the data set communicated by the measurement unit can be stored in the server, and the server includes an interface for exchanging data with additional units in the configuration.

In other embodiments, the measuring unit and the base unit may both form an integrated device, and may be encapsulated, for example, in a common housing.

The mobile measurement unit can be designed as a portable handheld device that can be positioned at the measurement position, for example by a field user. The measuring unit includes at least one measuring device for identifying the internal structure or internal state of the component. As an example, the state of the stiffener in the reinforced concrete element can be identified by measurements of induced eddy currents and / or conductivity. The mobile measurement unit has an interface for exchanging data with additional units in the configuration, particularly the base unit. The measurement unit may thus be linked to a base unit or an additional unit in the configuration via, for example, a wireless local area network (WLAN). Of course, wired links are also possible. In this way, the identified measurement data of the measurement unit and, where appropriate, the location data of the detection means may be automatically communicated to the base unit, for example. Communication may occur directly upon detection of the measured value, or at predetermined or adapted time intervals. For this purpose, the measurement data may be stored in a buffer within the measurement unit. It goes without saying that a manual initiation of the transfer may also be necessary, or that the transfer will only occur after the measuring unit has been linked to the base unit, for example by a cable connection.

In this case, the "measurement position" may refer to a position designated with respect to a global coordinate system such as GPS coordinates. The measurement position can also be specified, for example, for the object itself, or for a local reference system of a positioning system specially designed for inspection of the object. Determination of the measurement position is, in particular, by photographic or film-based detection of the measurement position, for example in the measurement process, or for additional features of an object having a known position, as described in more detail below. , Can be done visually or specified.

The detection means may be designed to manually enter the measurement position, for example a sequence. The measurement position can also be realized, for example, by manually marking the measurement position on a virtual model of the object represented on the measurement unit. For this purpose, the detection means may be integrated into the measurement unit, for example as a keypad and / or as a touch-sensitive screen. It goes without saying that the detection means may further include a receiver for signals of satellite-based (eg GPS) or Global Positioning System on the ground, the receiver being implemented, for example, within a measurement unit. The receiver can also be similarly set up, for example, in the field at an object to establish a coordinate system and designed to receive signals from one or more radio beacons that allow, for example, triangulation of measurement positions. .. Identification of the measurement position can be started automatically when the measured value is detected.

The required functionality of the individual units or means may be achieved via hardware and / or software, depending on the requirements. Dialogue between field users may also be necessary depending on the requirements.

The separate base unit allows, for example, additional users in the field, but not necessarily in the measurement position, to monitor the detection of measurements. In particular, in the base unit, the detected measurements can be assured that they are achieved at the exact measurement position given, for example, in the inspection plan. In particular, whether or not the measured position and measured value were entered in the correct position, for example, in the planning of the object stored in the base unit, especially in the construction plan of the building stored in the base unit, at the site of the object. It is also possible to check directly with. If there is an indication of false or incomplete detection, the expert inspector can influence the progress of the inspection in the base unit, for example, to carry out procedures for updated or additional performance of the measurement. Further users in the field at the base unit can now be monitored in an environment where inspection is convenient, with access to various additional information that the above additional users can obtain, for example, over the network. Has advantages.

Thanks to the fact that measurements are made non-destructively according to the invention, for example an overview of the internal state or structure of a concrete part, for static or construction engineering reasons (eg lack of space, inaccessible places). ), Can be obtained quickly even in places where it is not possible to take core samples for laboratory analysis. Thus, the configuration allows for direct measurement of internal structural defects and / or failures, for example due to externally identifiable defects, rather than just assumptions. In particular, defects that are invisible from the outside can be identified regardless of the perception of the user in the field. Thus, the composition is particularly broad and can also be used, for example, to approve newly created objects. As an example, a measuring unit of this configuration, designed as a reinforcement tester, can be used to test whether the reinforcements in the concrete elements of a building are consistent with structural specifications. Such structural defects are not visually recognizable.

For the base unit, these data identified directly in the field at the object can be integrated and visualized, for example, into a data model or data structure. As a result, it may be recognizable that further measurements and / or visual inspections must be performed directly in the field, eg, due to internal defects identified near the measurement location. The data identified by different measuring units can be centrally acquired by the base unit, thanks to the fact that the measuring units, in particular even multiple, preferably different measuring units, can be linked to the base unit. In this case, the base unit can, for example, integrate the different identified data into an existing data structure that reproduces the internal state of the measurement elements of the object, especially the measurement parts of the building. The data structure may be storable within the base unit. In particular, the data structures as a whole may provide a comprehensive virtual model of the object that reliably reproduces the current state of the object, as well as planning and further information about the object, especially construction planning for buildings. And may contain more information. Therefore, all linked measurement units have access to the updated central data structure without excessive synchronization expenditure.

In this case, the data structure may further include the measurement data of the previous inspection so that the history of the element or object, especially the part or building, can be detected. Data structures that are supplemented with data about the internal structure of the element, especially the part, can be visualized or output by the base unit, for example as a virtual model or otherwise. Alternatively or additionally, for example, data structures and / or visual representations may be stored or generated on the server, and the base unit is linked to the server (see below). It goes without saying that the base unit is further designed to collect and transfer the data set obtained by the configuration according to the invention, if necessary. The data structure of the data and, for example, visual conditioning can be implemented in this case on the server.

Ultrasonic measurement is, in principle, based on pulse velocity measurement of ultrasonic pulses. Waveform analysis can be used to draw conclusions about the properties of building materials. In this way, it is possible to both check the homogeneity of the building material and demonstrate defects. Pulses or velocities are related to the density and elasticity of the building material under test, allowing statements such as quality and compressive strength.

In transmission radar measurements, the internal structure of the component is measured by the reflection of electromagnetic radiation at the defect. In this case, a generally very short electromagnetic pulse with a length of a few picoseconds to a few nanoseconds is emitted inside the component and the reflection is captured. In this case, the propagation of the electromagnetic waves inside depends on the structure located inside the component that causes the reflection, scattering, diffraction and transmission of the signal radiated inside. The flight time, phase and amplitude of the reflected signal are usually recorded.

In eddy current measurements, an alternating magnetic field is generated, for example by a coil, to induce eddy currents in a conductive building material. At the time of measurement, the eddy current density as a result of the magnetic field generated by the eddy current is usually detected using a sensor that also includes an excitation coil. Measurement parameters generally include amplitude and phase shift with respect to the excitation signal. They are usually measured using a second coil in the sensor. Occasionally, other magnetic field sensors such as GMR sensors (giant reluctances) or so-called SQUIDs (superconducting quantum interference devices) are also used. Eddy current testing takes advantage of the fact that most impurities and damage examples in conductive materials also have different conductivity or different magnetic permeability than the actual material.

Measuring electrical resistivity provides information about the condition of parts, such as reinforced concrete elements. Resistivity is closely related to the potential for corrosion and the rate of corrosion. Similarly, resistivity can directly correlate with chloride diffusion rate. At the time of measurement, the first electrode pair is generally brought into contact with the building material. A voltage is applied between the electrodes. Then, the potential difference between additional pairs of electrodes is measured. From there and from the configuration of the electrodes, the resistivity can be calculated.

The potential field measurement may involve confirmation, for example, whether or not a corrosive effect is present in the reinforcing material in reinforced concrete. In this case, the electrochemical potential between the steel and the concrete, or more precisely between the steel and the half-cell placed on the concrete (eg copper / copper sulphate reference electrode), is constant over the entire concrete range. Measured at intervals. From the potential field thus identified, the anode and cathode regions can be identified. If the region has an anodic potential, the steel is corroded, or at least in particular at risk of corrosion.

In the rebound measurement, the strike pin is basically accelerated in the measurement unit, and the strike pin hits the building material and rebounds. The harder the building material, the more the pins will rebound. The rebound distance is, for example, shown on the scale or automatically detected and is a measure of rebound energy. From this, the strength of the building material can be read. A series of measurements can identify the internal structure of the building material based on different compressive strengths.

It goes without saying that the configuration may include a plurality of measurement units based on different measurement principles. Similarly, an individual measuring unit may further include measuring devices for multiple measuring methods. It goes without saying that it is also possible to utilize a measurement unit suitable for other non-destructive measurement principles to measure the internal structure or state of the component. However, this choice of measurement method has been found to be economically feasible and suitable for everyday use.

In one preferred embodiment of the configuration, the detection means specifically comprises a mobile capture unit, which is capable of identifying measurements using the mobile measurement unit, especially by a user in the field, on a photograph and / or on film. Designed to be captureable by a capture device, it can be positioned or positioned prior to a particular measurement at a measurement location. In this case, the capture unit is designed to be preferably mobile and as a separate, freely positionable unit. The unit is advantageously designed so that the user in the field can carry the unit. In particular, the unit may be correspondingly dimensioned and have a corresponding weight for this purpose. In one advantageous embodiment, the capture unit is placed on a helmet worn by a user in the field. This makes it possible to capture at least substantially the user's field of view, especially while the user is performing measurements using the measurement unit. The capture unit is preferably linked or linkable to the base unit via an interface, which may be wired or wireless. Where appropriate, the capture unit may be further linked to the measurement unit, which may also be wired or wireless.

In this case, the capture unit can simultaneously detect, for example, an area of an object whose measured value is specified at different measurement positions, especially in a fixed field of view. The field of view preferably includes at least a mobile measurement unit and / or a field user at the time of identifying the environment of the measured value and the measured position. For this purpose, the capture unit may be positioned by the user in the field prior to the specific measurement. Thanks to the fact that the capture unit records measurement identifications, for example in photographs and / or on film, which measurements were identified at which location on the object and, where appropriate, which in the field they were. It is undoubtedly possible to prove later that it was identified by the user.

The capture unit may include a buffer storage device (buffer memory) that stores shots captured in a limited time (eg, 5 seconds) according to the FIFO principle (first in, first out). In this way, it is possible to store capture shots before, during, and after a particular measurement at any measurement time. The capture time can be automatically initiated by the measurement performance, for example, by the measurement unit. In this case, the capture unit, eg, its field of view, can serve as a reference system for identifying the measurement position. The capture unit may also include, for example, a radio beacon for locating the measuring unit by radio waves.

Preferably, at least one field of view including at least the user at the time of specifying the measured value and the environment of the measured position can be detected by the capture unit. In this way, the size relationship and the position of the user in the field when performing the measurement can be recognized on the capture shot. For this purpose, the capture unit may include, for example, a wide-angle or panoramic camera. It goes without saying that conventional cameras can also be used, assuming a suitable design.

The configuration may include a triangulation system. In this case, a triangulation system refers to a system in which the position of a measuring unit, in particular the measuring position, can be identified by the system during the measuring process, for example based on ground and / or satellite signals. As an example, a radio beacon or a field antenna system on an object can be used as a ground triangulation system. As an example, a global positioning system such as GPS, which can be used free of charge, can be used as a triangulation system using satellites.

The configuration, in particular the mobile measurement unit, may optionally or additionally include a displacement capture system, which can be used to identify the movement of the mobile measurement unit. The displacement capture system may include, for example, a wheel that rolls along the surface of the object to be inspected during measurement. The movement of the mobile measuring unit can be inferred from the rotation of the wheel. For this purpose, the wheel may include a magnet and its movement is inductively confirmed.

Needless to say, the detection means in the deformation may further include the coordinate grid, and the coordinate grid is projected by, for example, a laser, and the measurement position can be specified by the coordinate grid.

The configuration may further include a marking unit, which allows the measurement position to be marked on the object. In this way, the measurement position can be directly and visually marked on the object for later reference. As an example, marking may be made using a separate marking gun (eg, in the form of a paintball marker). However, preferably, the marking unit is integrated into the measurement unit so that the measurement position can be marked at the time of specifying the measured value.

The marking may include color marking, or fluorescent marking that becomes visible only with special light, eg, if the area to be marked is not visually impaired. The marking unit may function in the form of an inkjet printer. In this way, it is possible not only to mark the measurement position, but also to record additional indications such as the type and time of measurement. The marking data may be communicated to the base unit in exactly the same way so that the data structure assigned to the object and the object itself contain the same marking indication.

The configuration may further include a macro capture unit, which allows the direct environment of the measurement location to be captured in photographs and / or on film. In this case, the macro capture unit should be distinguished from the capture unit described above in the sense that the macro capture unit is provided to capture a detailed view of the measurement location. The macrograph serves to record the state of the component at the measurement position in detail. For this purpose, the macro capture unit may include a camera and / or a microscope camera suitable for macrographs. Preferably, the macro capture unit is integrated into the measurement unit so that the direct environment of the measurement location can be captured while identifying the measurement value. In this way, the macro capture unit ensures that the exact measurement position is captured during, immediately before, or immediately after the measurement.

Similarly, alternative or additionally, the configuration may include an inertial navigation system. The inertial navigation system allows the current position to be determined by integrating data from accelerometers, for example, from a known starting point on the object. Such systems generally have a total of 6 degrees of freedom in kinematics, 3 of which are translational and 3 of which are rotational, which are oriented at similarly three unit vectors located orthogonal to each other. Attached. This sensor assembly allows the body coordinate system to be identified in real time and compared with a fixed, previously known spatial coordinate system by kinematic transformations, allowing application as a navigation system.

In the first variant, the inertial navigation system can be integrated into the capture unit of the detection means. The direction in which the capture shot is captured by the capture unit can thereby be identified in a particularly simple manner. However, in the second variant, the inertial navigation system can also be integrated into the macro capture unit. The direction in which the captured shot is captured by the macro capture unit can thereby be identified in a particularly simple manner. This is especially advantageous when the macro capture unit is integrated into the mobile measurement unit and the direct environment of the measurement location is captured.

The configuration may include a monitoring unit temporarily or permanently attached to the object to repeatedly identify the measured value at the selected measurement position, the monitoring unit being described in more detail below. It has an interface for exchanging data with additional units, especially the base unit and / or the server. The monitoring unit may be designed, for example, to perform at least one or more of the following measurements:
-Ultrasound measurement,
-Radography,
-Eddy current measurement,
-Electrical resistance measurement,
-Potential field measurement,
-Rebound measurement,
-Acoustic resonance analysis,
-Inductive reinforcement position detection,
-Capacity type reinforcement position detection,
-Underground detection radar,

In terms of measurement, the monitoring unit can be designed very similar to the measurement unit as described above. However, in the case of a monitoring unit, in principle, it is also possible to apply other measurement principles outside the component, such as for visual inspection, especially for pure visual inspection. However, in principle, the surveillance unit does not have to be mobile and may omit input and output means. The monitoring unit may include an interface for linking to an external network such that the measurement data can communicate directly with the network service unit without bypassing, for example, through the base unit.

The configuration, in particular the measuring unit, may further include a recording device, which may include at least one acceleration value and / or moisture value and / or temperature value and / or specific radiation value of one of these values. When at least one predetermined threshold is exceeded, it is preferably detected with the measurement time and / or the measurement position. Such a recording device may be aware of possible damage to the measuring unit that may affect the measured value. The recording device may be located within the measuring unit or within the base unit. As an example, the high acceleration of a measuring unit may indicate that the measuring unit may have been inadvertently dropped by the user and thus no longer yield reliable measurement results. The recording device can therefore have the function of a "black box".

In addition to the measured values identified by the measuring unit, as well as the measured position and / or measured time detected by the detection means, the data sets communicable to and storable in the base unit may be, for example, distortion values and / or measurement times. / Or moisture and / or temperature and / or specific radiation and / or acceleration and / or further include at least one additional measurement, such as the measurement specified by the monitoring unit as described above. obtain.

The interface of the base unit is advantageously designed to link to a public or proprietary network, while the configuration includes a server to which the base unit is linked to exchange data over a public or proprietary external network. It is linkable and the server is preferably accessible to authorized users over a public network. In this case, the server may be a specific embodiment of the network service unit described above, whereby the service may be provided or realized via the network.

In this case, the server is designed to receive data from the base unit and store the data. The data can be conditioned by the server as well. The server could make the identified data available to third parties who are only allowed access to the server, regardless of the base unit, but could be used in the configuration of the invention for inspection. It has the advantage over the base unit that it does not. Such authorized users may be, for example, a customer of the provider of the configuration described in this case, or a member of a building authorization authority, which may thus have direct access to inspection data. In particular, authorized users can virtually directly track the inspection of an object and, where appropriate, can influence the inspection, for example by instructions described in more detail below.

Preferably, the server comprises at least one stored data structure assigned to the object to be inspected. In this case, the server is designed to supplement the data structure with the data communicated by the base unit and to provide the supplemented data structure to authorized users, especially in real time. In this case, the data structure forms a uniform format for data from different sources. On the other hand, the data structure may include external data about the object, in particular external data about the building, such as historical inspection data and / or technical specification or reference data about the construction plan, elements, especially parts of the building. On the other hand, the data structure can be supplemented by the server with the data or dataset of the base unit, including the measurements of the measurement unit or, where appropriate, the measurements of the monitoring unit. Similarly, capture shots, especially of mobile capture units and / or macro capture units, can be integrated into the data structure. The server therefore forms a so-called data warehouse where data about objects from different sources can be combined (information integration) and provided, for example, in a uniform format. This improves the convenience of accessing the data of the object.

The data structure is preferably configured such that the data structure can provide a virtual accessible 3D model of the object to be inspected, especially the building to be inspected, to authorized users and / or field users by the server. Will be done. In this context, "accessible" refers to the ability of an authorized user to move predominantly within a virtual model, for example as a so-called avatar. In this case, field users can be represented simultaneously as avatars in the same model, allowing dialogue between authorized users and field users, for example, through a server, and some sort of "field" team meeting. Can be brought. Assuming a corresponding design, the virtual model is, for example, on a base unit and / or on a measurement unit and / or on a head-up display, especially on a head-up display of eyeglasses that can be worn by field users or authorized users. It can be expressive.

The data structure and the virtual model based on it are preferably continuously scalable by the server with the data communicated by the base unit with respect to the internal structure and / or internal state of the parts of the measurement unit. In this way, it is guaranteed that the model given by the server is up-to-date and that the inspection can be monitored in real time, for example by an authorized user.

In the above virtual model, the data structure and / or the original and / or derived dataset and / or the measurement and / or capture instructions and / or at least one additional so that a "virtual magnifying reality" model occurs. It is possible to superimpose instructions for specifying the measured value in real time. As an example, the measurement location is marked and referenced in the virtual model so that the desired information about the internal state and / or internal structure can be retrieved, assuming the behavior of the user's response (Internet page reference (hyper). It can be realized as (link) as well. In the virtual model, the internal structure can be visually represented, for example, through a translucent wall, and additional information can be inserted, such as setpoint values or computationally simulated values for reinforcement corrosion. In this case, critical measurements for internal defects or defect areas can be highlighted, for example, in color.

Preferably, the server comprises a library of programs that allow the dataset of data structures selected in the manner targeted by the authorized user to be conditioned and / or retrieved. Thus, for example, a three-dimensional view can be generated first, and then an object report, in particular a building report, from the data structure. In this case, the program in the library can first extract the corresponding relevant data from the data structure and then condition it to the desired form.

Advantageously, the instructions may be communicated by authorized users via the server. As an example, measurement instructions may be able to communicate with the base unit and, where appropriate, from the base unit to the monitoring unit and / or the mobile measurement unit and / or field users. Measurement instructions are preferably communicated directly to the measurement unit, especially if the measurement unit is remotely controllable. The measurement instruction may include, for example, the measurement position and / or the measurement time and / or the type of measurement intended to be performed by the user in the field. Communication of one or more measurement instructions can take place in real time. However, alternative or additionally, the one or more measurement instructions may be further precompiled and then made available as a collection to users in the field. The measurement instruction or multiple measurement instructions may be compiled prior to inspection of the server, for example in the form of an inspection plan for users in the field. Where appropriate, the desired measurement position may be represented within the virtual model. However, preferably, the measurement instructions are communicated to the field user in real time so that the inspection can be directly influenced, for example, by an authorized user. Authorized users do not need to be in the field of the object for this purpose.

Alternative or additional, at least one additional measurement, such as strain and / or moisture and / or temperature and / or specific radiation and / or accelerometer-specified accelerometer. It is possible to communicate an instruction for identifying the detection means to the detection means. Communication of additional measurements is preferably done in real time.

Similarly, alternative or additional, the capture instructions may be communicated specifically to the mobile capture unit and / or to the macro capture unit, preferably in real time.

The measurement instruction and / or the instruction and / or the capture instruction for identifying at least one additional measurement value may include an indication about the measurement position where the measurement or capture is intended to take place. In this case, it is conceivable that the measurement or capture will be performed automatically when the predetermined measurement position is reached. The configuration, in particular the measurement unit or macro capture unit, may or may not be programmed correspondingly for this purpose so that the measurement or capture is subsequently performed automatically.

The server may be designed as a local server unit, for example in the provider of the configuration for building inspection described in this case. However, preferably, the server is provided as an information technology infrastructure that can dynamically adapt to demand, especially as a cloud-based server. In this way, the capacity of the server can be expanded as needed without any problems. As an example, the server can be scaled accordingly if the data structure is particularly comprehensive due to the high complexity of the object, or if there are special requirements on the part of the authorized user regarding the quality of the visual representation. .. As demand diminishes, unnecessary resources can be cost-effectively eliminated.

The nonlocal server structure of cloud-based servers further ensures that the data available on the server or the services provided by the server remain available in the event of an individual area of the server failure. .. The scope of services offered in the context of cloud computing in this case covers the entire spectrum of information technology, including, among other things, infrastructure such as computing power, storage capacity, platforms and software.

A further aspect of the invention relates to a method for inspecting an object, in particular a building, which is realized, in particular using a configuration as described in this case. The method consists of the following steps, ie
-Steps to non-destructively identify measurements with respect to the internal structure and / or internal state of a particularly inaccessible element of an object, especially a part of a building, by a mobile measurement unit.
-The step of detecting the measurement position where the measured value is specified and / or the measurement time when the measured value is specified by the detection means, and
-In particular, the step of automatically communicating the measured value identified by the measuring unit to the base unit via the data interface as a data set, together with at least the measured position detected by the detection means.
-Includes steps to store the dataset in the base unit.

The measuring unit can be operated by a user in the field. However, it is considered that the measurement unit can be remotely controlled and no operation by the user is required, which is within the scope of the present invention.

The advantages of this method are directly evident from the configuration for inspecting objects, especially buildings, as described in this case.

The method further includes the following steps, i.e.
-The server includes a step of communicating from the base unit to the server, preferably via a public or proprietary network, a data set that specifically contains measurements regarding the internal structure and / or internal state of particularly inaccessible components. Contains at least one stored data structure assigned to the object of interest, and further
-Steps to supplement the data structure with the dataset communicated by the base unit,
-It may include steps to give the data structure to authorized users and / or field users, especially in real time, as a virtual accessible 3D model of the object to be inspected, especially on the server.

As an alternative to the embodiments described above, the data structure may further be provided on the base unit or heads-up display.

In non-destructively identifying measurements relating to the internal structure and / or internal state of the component, preferably at least one of the measurement methods already described above is used. Similarly, the method may include positioning a detection means specifically designed as a mobile capture unit at the measurement position, in particular the mobile capture unit may be photographed by the capture device and / or the identification of the measured value by the user in the field. Positioned prior to a particular measurement so that it can be captured on film. In this case, in particular, the mobile capture unit preferably detects a field of view including at least the user at the time of specifying the measured value and the environment of the measured position.

It may be advantageous to make the server accessible to these people in order to train people about the configuration of the invention and / or the use of the method according to the invention. Permission may be limited temporarily and / or to certain rights. As an example, permissions may be restricted to read access so that, for example, the person does not have the right to supplement and / or modify the data structure stored by the server. However, the person may be allowed to receive data from the server, for example, to represent the object to be inspected as a virtually accessible 3D model.

Further modifications of the method are evident from the configuration for inspecting objects as described in this case.

The invention will be described in more detail with reference to the drawings of exemplary embodiments.

It is a block diagram of the structure which concerns on the invention including a server. It is a figure which shows the exemplary embodiment of the base unit of the structure which concerns on invention, the detection means designed as a capture unit, and a measurement unit. It is a figure which shows the measurement by the user in the field. It is a diagram showing various views that can be generated, for example, from a data structure assigned to a building or from a virtual model, for example, by a program routine. It is a block diagram with various views of how a supplementary data structure can be represented as a supplementary virtual model after the inspection is performed. It is a figure which shows the visual reproduction expressed on the screen using a timeline.

FIG. 1 shows a block diagram of a configuration 1 according to an invention for inspecting an object designed as a building 2, wherein the configuration includes a server 3. FIG. 1 shows a functional unit as a separate block that can be embodied separately or combined as part within a single device in a particular embodiment. In this case, the server 3 may be designed as a local server unit, for example, in the provider of configuration 1. The server 3 can also be embodied as a nonlocal cloud-based server 3.

The server 3 includes a library of different applications 4, whereby the data or data structures stored on the server 3 can be analyzed, processed and / or managed, for example. Depending on the situation, the application 4 may be provided, for example, by the authorized user 7 itself to enable personalized data processing. In this case, the program library 5 of the server 3 having, for example, standardized program routines for 2 and / or 3D output of data, text output and / or other data conditioning is accessible.

The server 3 includes a database 6 in which data can be stored. The data is preferably stored in a defaulted or dynamically adaptable, standardized data structure that allows uniform access to a wide variety of data. In particular, as an example, image files, audio files and data files or individual data points can be combined within a uniform data structure. In this case, the data structure may be assigned, for example, to the building 2 that has been inspected or is inspected. Thus, for each building 2 inspected by configuration 1, a comprehensive collection of information can simply be provided in a widely accessible data format. The data structure preferably has at least the data of the 3D construction plan of the building 2 to be allocated. The above data may be expanded, for example, with historical data from previous examinations. Similarly, for example, the processed building material of individual parts may be stored.

It goes without saying that the server 3 has, for example, a computing unit and an interface for exchanging data in order to provide the required functionality. A server 3 is further designed or a program routine corresponding to the program library 5 to map the data or data structures stored in the database to the visually representable 3D virtual model 9 of the building 2. including. The conversion to visual representation may be performed, for example, by a client-side application on the personal computer of authorized user 7. Similarly, the visual representation may be further implemented on the server 3 and transferred as an image or film file to the authorized user's computer.

The virtual model 9 is preferably realized as an accessible interactive virtual model 9. The authorized user 7 or the field user 10 engaged in the inspection of the building 2 can therefore "enter" the virtual model 9. In this case, the user may exist purely as an observer in the virtual model 9 or may be represented by a so-called avatar. For this purpose, the model 9 may have input possibility through which the authorized user 7 and / or the field user 10 or its avatar may interact with the model 9. As an example, the identification location in the virtual model 9 can be embodied as an bootable reference (similar to an internet page reference-hyperlink-) that references additional data. In this case, for example construction data such as the type of concrete used, the planned number of reinforcements in the concrete, or historical data of previous inspections can be retrieved by dialogue.

Preferably, the data can be further input via model 9. In particular, identification locations where measurements are intended to be performed, for example by field user 10, may be marked in model 9 by authorized users or their avatars. The stored data and / or data structure can be modified in this way and specifically supplemented in this way by dialogue with model 9. Further possibilities for such accessible 3D virtual model 9 of the building 2 to be inspected can be given directly in connection with test configuration 11, as described below.

The test configuration 11 includes at least one base unit 12 and one or more measurement units 13. Along with the measurement unit 13, the test configuration 11 may include a detection means 14 for detecting the measurement position and / or the measurement time at which the measurement is performed by the measurement unit 13. Further, there may be a marking unit 15, which allows the measurement position of the measurement to be marked on the building 2. In addition, a macro capture unit 16 may be present, which may create a visual macrograph of the measurement position with its direct environment. The capture is preferably performed immediately before, during, and / or immediately after the measurement by the measuring unit 13.

The detection means 14 may include a capture unit capable of visually detecting a portion of the building 2 in which the measurement is performed together with the user 10 in the field. Such a capture unit may be further designed as a separate capture unit 17, for example as an additional detection means. As an example, the detection means 14 may be integrated into the measurement unit 13 and include a triangulation system, whereas the separate capture unit 17 serves for additional visual detection of the measurement position. The capture unit 17 will be described in more detail with reference to, for example, FIG.

The measuring unit 13, the detecting means 14, the marking unit 15, the macro capture unit 16, and the separate capture unit 17, if necessary, are preferably linked to the base unit 12 for data exchange over the network. In this case, the data exchange can be automatic and, for example, directly if there is a change in the data structure. It goes without saying that the data being inspected can also be stored in the individual units 13 to 17 and cannot be transferred to the base unit 12 until later. The network may be wired or wireless, and proprietary or public networks may be used in each case.

The base unit 12 is linked to the server 3 via additional or identical networks. The data from units 13 to 17 can therefore be transferred to the server 3 via the base unit 12. The server 3 supplements the data structure assigned to the building 2 with communication data. Supplements can be accepted, for example, in real time within a data structure. The virtual model 9 generated from the data structure can also be supplemented in real time. In this way, the user 7 or 10 may be notified in real time, for example, about the measurements made. It goes without saying that the data can be transferred via the base unit 12, for example, from the server 3 to, for example, the measurement unit 13. Such data may include, for example, a measurement instruction generated by the authorized user 7, which is displayed to the field user 10 on the display of the base unit 12 and / or the measurement unit 13.

One exemplary sequence is:
The user 10 in the field performs the measurement for the measurement instruction, and the user is detected by, for example, the capture unit 17. The data thus obtained, for example, the measured value of the measuring unit 13, the detection position detected by the detection means 14, and the captured overview shot of the capture unit 17 including the user 10 in the field when performing the measurement. , And / or the macrograph of the macro capture unit 16 may be communicated to the server 3. The server 3 supplements the data structure and, if appropriate, generates a supplementary virtual model 9. The authorized user 7 is therefore accessible to the supplementary data and can check the data, for example for quality and / or integrity.

The test configuration 11 may further include, for example, at least one monitoring unit 18 fixedly placed in the building 2. The monitoring unit 18 is linked to the server 3 and / or the base unit 12. The monitoring unit 18 may capture the measured values of the parts of the building 2 in the same manner as the measuring unit 13. However, in contrast to the measurement unit 13, the monitoring unit 18 in this exemplary embodiment is designed as a static unit for continuously communicating measurements.

FIG. 2 shows an exemplary embodiment of a detection unit designed as a base unit 12 and a separate capture unit 17, and a measurement unit 13. The measuring unit 13 is described below as an example with reference to a reinforcing material testing device based on eddy current technology.

The base unit 12 has a screen 20, which in this case is designed as a touch sensor type for inputting data. The base unit 12 has a protective housing 21 with a cover 22, whereby the screen 20 may be protected. Further, means 23 for positioning the base unit 12 in a desired position may be implemented on the protective housing 21. The base unit 12 can be designed substantially similar to a robust laptop or tablet computer, such as those used in the art. The base unit 12 may further have a keypad 24, which may be used for input.

The measuring unit 13 has a measuring device (which cannot be discriminated here) designed to execute each of the measured methods used. In this case, these are, for example, coils for performing reinforcement tests using eddy currents in reinforced concrete, for example. The measurement unit 13 includes a similar touch-sensitive screen 26 for expressing and inputting data.

Further, the measuring unit 13 includes four wheels 25, which may roll along the surface of the object to be inspected at the time of measurement. One of the wheels 25 includes a magnet (which is indistinguishable here) and its movement can be inductively confirmed. The trajectory along the measurement unit 13 as it is guided over the surface of the object can be specified with particular precision in this way.

The capture unit 17 has a camera 27 with a relatively large field of view so that the area of the building 2 can be detected within the overview 35 (see, eg, FIG. 4). If desired, the camera 27 may include a wide-angle lens or fisheye. The camera 27 may be further designed as a panoramic camera.

FIG. 3 schematically shows how a user 10 in the field can make a measurement. The user can specify the measured value of the object 2 by using the mobile measuring unit 13. Since the measured values are affected by the defect 42, it may provide information about the presence of the defect 42. The measurement unit 13 is connected to the base unit 12 via an interface for exchanging data, and the data set communicated by the measurement unit 13 can be stored in the base unit. The base unit 12 further has an interface for exchanging data with the proprietary or public network 3. Alternatively, the interface of the base unit 12 may be further designed to exchange data directly with the server. A macro capture unit in the form of a camera 16 is arranged on the measurement unit 13, and an accurate measurement position can be recorded by using the macro capture unit. An additional camera 44 placed on the helmet of the user 10 in the field substantially detects the field of view of the user 10 in the field. Further, the field of view of the camera 17 detects the user 10 in the field at the time of measurement. The monitoring unit 18 is fixed to the object 2, and the monitoring unit can be designed, for example, as a humidity sensor or a temperature sensor. The monitoring unit 18 further has an interface for exchanging data with the network 3.

FIG. 4 shows view 30 which can be generated from the data structure assigned to building 2 or from virtual model 9 by, for example, the program routine of program library 5. View 30 shows a two-dimensional plan view of a part of the building 2. The desired position of the capture unit 17 and the desired viewing direction and viewing angle 31 are displayed in the view 30. Further, the measurement position 32 is marked on a different part 8 of the structure 2 in the field of view of the capture unit 17. The view 30 can therefore be regarded as a measurement command to the user 10 in the field. It goes without saying that the view 30 also indicates the situation in this region after the measurement has been made, in which case the marked measurement position 32 can be designed, for example, as an bootable reference, through which, for example, the measurement. Measurements can be accessed.

View 35 of FIG. 4 shows the field of view of the capture unit 17 along with the inserted measurement position 32 of the component 8. In this case, the view 35 can be understood as, for example, a three-dimensional view of the virtual model 9 already supplemented. The view 35 can also be viewed as a three-dimensional view of the measurement instructions to the user 10 in the field, which may be represented, for example, on the base unit 12 or the measurement unit 13. In this case, the user 10 in the field is notified of the place where the user must perform the measurement. In this case, the color of the marked measurement position 32 may indicate, for example, the desired measurement type.

View 36 shows a macrograph of the direct environment of one of the measurement positions 32, as captured by the macro capture unit 16. The macrograph can be called, for example, by mouse click or by another dialogue with the corresponding measurement position 32 in the virtual model 9.

View 37 shows a visual representation of the identified measurement. The measuring unit 13 identifies the position and state of the reinforcing material 38 in the component 8 by, for example, one or a plurality of measurements. The measured values are processed by the base unit 12 or the server 3 into a visual representation of the raw data. The visual representation may be recalled, for example, by a mouse click or by another dialogue on the corresponding measurement position 32 within the virtual model 9.

View 39 shows detailed information about an excerpt from view 37. The information represented may include, for example, additional information from a library of construction materials to be used, or may be calculated, for example, from the measurements of measurement unit 13.

Finally, view 40 shows a superposed view according to views 36, 37 and 39, as can be represented within virtual model 9. Further, for example, accurate spatial coordinates of the measurement position specified by the detection means 14 can be inserted (X, Y, Z).

FIG. 5 shows a schematic diagram of how the supplementary virtual model 9 can be represented after the inspection has been performed by the user 10 in the field. The identified measurements and additional data are included in Supplemental Model 9 (arrows). The three-dimensional representation 35'of the supplemental model 9 can be retrieved onto the server 3 by the authorized user 7. In this case, the authorized user 7 is, for example, a professional service person 7
It can be a, the owner 7b of the building 2, or the employee 7c of the inspection company.

View 35', which corresponds to the field of view of the capture unit 17 in view 35, indicates the user 10 in the field when performing the measurement. The measurement position 32 is marked and can be realized as an interactive reference 41. Information on a large number of items linked to it may be retrieved via reference 41. As an example, view 36 of the macro capture unit 16 may be retrieved. The composite view 40 can be called as well. It goes without saying that the measurement position 32 of the view 35'can be directly represented as, for example, the composite view 40.

It goes without saying that all views can be supplemented with text fields 40'where details about the measurement, such as the time or type of measurement, may be displayed. The result of the analysis of the measured values may be similarly displayed, for example "corrosion 10%". Needless to say, supplementary data such as a viewing angle 31 of the capture unit 17 in view 35 and / or a two-dimensional representation according to view 30 can also be collected from model 9. Further data in the data structure is accessible as well, which provides information, for example, about the standards to be compiled for component 8 or about previous inspection data.

FIG. 6 shows a visual reproduction represented on the screen and including the timeline 45. The history of many measurements is represented along the timeline 45. As shown in FIG. 6 as an example of an eddy current measurement performed on the same day, the individual can retrieve the desired information about the internal state and / or internal structure, assuming a user-responsive operation. The measurement is marked and realized as a reference.
