Description

Arrangement and method for inspecting an object, in particular a building

The invention relates to an arrangement and a method for inspecting an object, in particular a building, according to the preambles of the independent claims.

Structures require regular and detailed inspections by qualified inspection specialists to record a condition of the structure. This also applies to many other objects. The inspections can provide information as to whether e.g. the structural integrity of the object

is guaranteed. Structures - especially buildings,

Deposits, bridges, towers, tunnels, roads and

Guards - must to ensure a

adequate usability and wear safety

be checked regularly. The verification takes place during the creation, during the use, a conversion and a possible dismantling of the buildings.

Such inspections sometimes require consideration of a variety of data and parameters. For example, in the inspection of structures material characteristics of

Components, operating parameters, regulations and recommendations from any standards and guidelines and, for. to consider special requirements for a component in the context of the entire structure. It is therefore a need

Inspection system to create the highest possible

Integration of a variety of data allows and this provides the inspection specialist clear.

Typically, the inspections of a building include a comprehensive survey of the structure in which Inspection-relevant situations such as defects and / or

Disturbances of the building or individual components are visually identified and recorded. The following will be without

Restriction of generality for inspection-relevant

Situations refer to defects exemplarily. A person skilled in the inspection analyzes these defects in a further step and, on the basis of this, derives a diagnosis, e.g. a type of defect or a topology of the defect. Due to the diagnosis, e.g. decided on further inspection steps and / or measures for the removal of the defects. This entails the risk that defects and their possible effects on the structure are overlooked and / or misjudged by the inspection expert.

The registration of the defects usually involves registering the defects on a diagram such as e.g. a blueprint of a building during the inspection by the inspection specialist. As a result, the registered defects are usually detected electronically, e.g. entered into a database or recorded in a CAD-based blueprint of the building or a model of the building created, for example, using a known 3D scanner. This approach has on the one hand

Disadvantage that the detection of defects only by the

Perception and care of the inspection specialist. However, the detection of the defects forms the basis for all further measures and should therefore have increased redundancy with which, e.g. the danger of faulty

Lessen entries or undetected defects. On the other hand, the transmission involves the diagrammatic capture

Defects in an electronic data collection the risk of transmission errors, eg due to incorrect input of numerical values. In addition, in hindsight it is not comprehensible at which point of the inspection a mistake occured. Furthermore, the multiple transmission of data is inefficient and labor intensive. For example, it can not be understood whether a defect was detected by the inspection expert at all or, for example, only later

Time, e.g. lost in the transfer of data.

An integrated system, which at least some of the

Attempts to fix existing disadvantages is in the US

6,725,097 Bl. This system allows the entry of visually detectable defects into a mobile input device, which the inspection expert carries with him during the inspection. The defects may be e.g. because of their visible

Structure classified according to a given selection and drawn on plans of the building. The defect may be e.g. manually via a graphical input program

Blueprint can be drawn or a photograph can be made on site. The input device can also

programmed algorithms include to analyze the entered defects.

While this system has improved interactivity and

Data integration, the detection of the

Inspection data as in previous systems only through the

Inspection specialist and thus has little or no redundancy. Thus, the advantageously automated analysis of the defects is based solely on the detected defects, ie the perception and care of the inspection expert in their detection. The system does not provide protection against defects which are overlooked upon detection, nor does it allow to subsequently determine whether a defect has been overlooked or occurred after the inspection. It is therefore an object of the invention to overcome the disadvantages of

Prior art overcome. In particular, it is an object of the invention to provide a versatile applicable arrangement as well as a versatile method for the inspection of an object, in particular a building, which enables a reliable detection of the actual state but also of structural defects. In addition, the arrangement and the method should be comfortable to use or execute and ensure high security. The arrangement and the method should also ensure that it is comprehensible at a later point in time at which point on the object, in particular on the structure, an inspection-relevant situation has been detected.

These objects are achieved by an arrangement and a method having the features of the independent claims.

These concern in a first aspect an arrangement for

Inspecting an object, in particular a building, comprising a mobile measuring unit for determining an object

associated measuring value, wherein the measuring unit has an interface for data exchange with other units of the arrangement, in particular a base unit. Furthermore, the arrangement comprises a, in particular mobile, base unit in which data sets transmitted by the measuring unit are storable and preferably visually representable and which has an interface for data exchange with further units of the arrangement, in particular at least the mobile measuring unit.

Preferably, the base unit also has an interface for exchanging data with a proprietary or public network. The arrangement also comprises a detection means for

Detecting a measurement position at which the measured value is determined, and / or for detecting a measurement time at which the measured value is determined. It is one of the measuring unit determined measured value at least together with a detected by the detection means measuring position, preferably

automatically, as a record to the base unit can be transmitted. The mobile measuring unit is non-destructive

Determination of measured values for an internal structure and / or an internal state of, in particular inaccessible,

Elements of the object, in particular structural elements of the building formed. The determination of the measured value can be carried out, for example, by a user on site who operates the measuring unit. As a user in the field, there is a user present on the object during the inspection, e.g. an inspection expert entrusted with the inspection,

designated. Alternatively, the measuring unit may also be such

be trained that they, for example, over the

Base unit, remotely controllable.

Under a building here and below is understood to be a construction constructed by humans with resting contact with the ground. The building may be, for example, a building, which is used for example for the residence of humans, the accommodation of animals, the cultivation of plants or the storage of things or the operation of machines. The building can also be a traffic structure, such as a bridge, a road, a tunnel or a tunnel. Alternatively, the building may also be a supply and / or disposal structure, such as a well, a water and / or sewer, a sewage treatment plant, a dyke, a dam, a dam, a weir, a chimney, a tower (such as a wind tower or a transmission tower), a mast or a transmission tower. Furthermore, the building may be a protective structure, such as a nuclear power plant or a protective wall, a protective dam, an avalanche barrier, a street gallery or a shelter. The building can also be a weir and / or

Fortification, such as a fixture or a Defense tower. In addition, the term "building" also includes mountain and Tagbauminen as well as temporary structures, such as flying buildings, tents, pavilions, auxiliary buildings, container buildings and

Deposits.

In addition to buildings, the term "object" used here and hereinafter also includes, in particular, movable objects, such as devices, machines, vehicles, aircraft, pieces of furniture, works of art (using the arrangement according to the invention and / or the method according to the invention

For example, their authenticity can be determined), but also living objects, such as plants, animals or humans.

An "internal structure" and an "internal state" are understood here and below as meaning a structure or a state of the object that is not visually recognizable, as is possible, for example, by a user with the naked eye or with the aid of a camera would. The terms "internal structure" and "internal state" thus include on the one hand

Structures and states inside the object. However, they also include structures and states which are present on a user-visible surface of the object or in the region of such a surface, but which are not visually recognizable. For example, in the context of the invention, an elasticity of the object in the region of a visible

Surface considered as an internal condition, as such

Elasticity is not visually recognizable.

The base unit and / or the measuring unit preferably comprise means for storing, processing, inputting and outputting and receiving and transmitting data. For storage and processing of the data, a memory unit and a computing unit may be present. In particular, the base unit be designed such that the data structures, programs, data records (original and / or derived data sets) and / or instructions described in detail below can be stored on the base unit.

The means for input may e.g. a touch-sensitive surface and / or a keypad and / or a microphone. About a touch-sensitive surface can be through a

Users, for example, drawings are recorded. One

Keypad allows a user to enter text

including numbers. About a microphone can a

Voice input. These data thus entered can then be used together with the / m, from the measuring unit

determined measured value and a / m, from

Acquisition detected detected measuring position and / or measurement time as a data set to the base unit and optionally stored there and / or further processed. In this way, a kind of logbook can emerge, in which it can be recorded, which user at which time and at which place has performed which measurement as and for what occasion.

The means for dispensing may e.g. comprise a printer via which, for example, a measurement protocol can be output. However, the means for dispensing are preferred

trained that object-specific, in particular

building-specific, data or data structures visually

are representable. A combined means for input and output may e.g. through a touch-sensitive screen

be provided.

As a visual representation can, in particular

three-dimensional, virtual model of the to be inspected

Object for the user on site on the base unit and / or the measuring unit visually present. With appropriate means for input, the user may optionally interact with the virtual model on-site, such as selecting views or marking measurement positions. Likewise, instructions may be presented to the user on site, such as

Measurement instructions for the user in the field, which e.g. a

Specify measuring position and / or a measuring time and / or a type of measurement.

In some embodiments, it may be sufficient if the arrangement contains only a single base unit. As a result, the expenditure on equipment can be reduced. Especially for the

Inspection of larger and / or more complex objects can be done

Arrangement but also contain several base units. These can then each have interfaces for data exchange

have one another.

The measuring unit is advantageously designed such that it can be worn by the user on site; In particular, it can be dimensioned accordingly for this purpose and a

have appropriate weight. Alternatively, the measuring unit may for example be placed or placed in or on a particular remotely controllable vehicle.

The base unit is preferably designed as a mobile unit which can be used by a user in the field, e.g. in the object,

in particular in a building, taken or outside the object, in particular outside a building, e.g. in or on a vehicle. The base unit is advantageously designed such that it can be worn by the user; In particular, it can be dimensioned accordingly for this purpose and have a corresponding weight.

Preferably, the base unit is eg in a suitcase or after Kind of a laptop or tablet computer trained. The

Base unit preferably has a protective housing which provides protection against mechanical damage, e.g. in the endangered environment of a construction site. Alternatively, the base unit

be placed or placed for example in or on a particular remotely controllable vehicle. The basic unit can basically also be used e.g. as maintenance or

Inspection terminal firmly on the object, in particular on the building, be arranged.

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 may be attached to a localized (e.g., server unit) or delocalized (so-called "cloud") network service unit. Accordingly, in particular in real time, data can be transmitted to or obtained from the network service unit. As external networks, for example, the Internet (public) or a mobile network (proprietary) can be used.

It is also possible and within the scope of the invention that the base unit itself is designed as a server or contains a server. A data exchange between the interface of

Measurement unit and the server can then be done via a proprietary or public network. In this embodiment, the data sets transmitted by the measuring unit are in this

Server storable, and the server includes an interface for data exchange with other units of the arrangement.

In other embodiments, it is also conceivable that the

Measuring unit and the base unit together an integrated device form and are enclosed for example in a common housing.

The mobile measuring unit may be designed as a portable hand-held device, which may be e.g. can be placed by the user on site at the measuring position. The measuring unit comprises at least one measuring device for determining internal structures or an internal state of the components. For example, the condition of reinforcements in reinforced concrete elements can be determined by measuring induced eddy currents and / or conductivity measurements. The mobile measuring unit has an interface for exchanging data with further units of the arrangement, in particular the base unit. The measuring unit can be in this way e.g. be connected via a wireless local area network (WLAN) to the base unit or other units of the arrangement. Likewise, of course, cable-based connections are conceivable. The determined measuring data of the measuring unit and

If necessary, position data of the detection means can be obtained in this way e.g. automatically transmitted to the base unit. The transmission can take place immediately upon detection of the measured values or at predetermined or adapted time intervals. For this purpose, the measured data can be temporarily stored in the measuring unit. Of course, a manual triggering of the transmission may be required, or a transmission will take place only after a connection of the measuring unit to the base unit, e.g. by connecting a cable.

In this case, "measuring position" can denote a position which, with regard to a, e.g. global coordinate system such as GPS coordinates. Likewise, the measurement position may also be relative to a local reference system, such as e.g. of the object itself or one specific to the inspection of the object

specified positioning system. A Determination of the measuring position can in particular also be carried out visually or indicated, for example by means of photographic or cinematic recording of the measuring process or of the measuring position in relation to other features of the object with known

Position, as more detailed below

is described.

The detection means may be used to manually enter the measurement position e.g. be designed as a number sequences. Likewise, the

Measuring position e.g. via a manual marking of the measuring position on a virtual model of the object displayed on the measuring unit. The detecting means may be used for this purpose e.g. be integrated as a keypad and / or as a touch-sensitive screen in the measuring unit. Of course, the detection means may also be a receiver for a signal

satellite-based (e.g., GPS) or terrestrial global positioning system, e.g. is formed in the measuring unit. Likewise, the recipient may e.g. be configured to receive signals of one or more beacons, which are set up locally at the object to create a coordinate system, and e.g. allow a triangulation of the measurement position. A determination of the measuring position can be triggered automatically when the measured value is acquired.

The required functionalities of the individual units or means may be implemented as required via hardware and / or software. Depending on the requirement, too

User interaction may be required on-site.

Due to the separate base unit, e.g. another

User on site, but not necessary at the measuring position, to monitor the acquisition of measured values. In particular, it can be ensured at the base unit that the acquired measured values at the correct measuring positions have taken place, as they are provided for example in an inspection plan. In particular, it is also possible to check directly on site for the object, whether the

Measuring positions and measured values, e.g. at the correct position in a plan stored in the base unit plan of the object, in particular in a stored in the base unit

Construction plan of a building, have been registered. If there are signs of faulty or incomplete detection, the inspection specialist at the base unit can influence the

Take the course of the inspection and, e.g. a renewed or

arrange additional execution of a measurement. The additional user on site at the base unit has the advantage that a monitoring of the inspection can be done in a comfortable environment and with access to various additional information that he can relate, for example, over the network.

By a measurement according to the invention takes place non-destructive, can also be found in places where static or

For structural reasons (e.g., lack of space, hard-to-reach locations), no core samples can be taken for laboratory analysis, a quick overview of the internal condition or internal structure, e.g. a concrete component can be obtained. In this way the arrangement allows a direct measurement of e.g. internal structural defects

and / or disturbances and not just their acceptance due to externally detectable defects. In particular, regardless of the perception of the user on site, invisible defects can be determined from the outside. In this way, the

Apply arrangement particularly versatile, eg also for the acceptance of a newly created object. For example, it can be checked with a designed as a reinforcement test unit measuring unit of the present arrangement, whether the reinforcements in a Concrete element of a building comply with the structural specifications. Such structural defects are not visually recognizable.

Due to the base unit, this determined data can be directly on-site at the object e.g. into a data model or a

Data structure integrated and visualized. Thus, it can be seen on the spot that e.g. due to a detected internal defect in an environment of the measuring position further measurements and / or visual inspections must be made. By the measuring unit, in particular a plurality, preferably different measuring units, are connectable to the base unit, which of the different

Measurement units determined data from the base unit are detected centrally. The base unit allows e.g. a

Integration of the different determined data in an existing data structure, which reflects an internal state of the measured elements of the object, in particular the measured components of the building. The data structure can be stored in the base unit. In particular, this can

Data structure also plans and other information about the object, in particular construction plans and other information about the building, include, so that a total of a comprehensive virtual model of the object can be created, which reliably reflects a current state of the object. All

connected measuring units can thus without excessive

Synchronization effort on an updated central

Access data structure.

The data structure can also measure data of earlier

Include inspections, so that a history of the elements or of the object, in particular the components or the structure, can be detected. The data with the internal structure of the

Elements, in particular of the components, supplemented data structure can for example be visualized or output as a virtual model or otherwise by the base unit. It is understood that alternatively or additionally, for example, the data structure and / or the visual representation can be stored or generated on a server to which the base unit is connected (see below). Likewise, it is understood that the base unit is, if necessary, also designed only for collecting and forwarding data records obtained with the arrangement according to the invention. The data structure as well as, for example, a visual preparation of the data can be done in this case on the server.

An ultrasound measurement is basically based on a

Pulse velocity measurement of an ultrasonic pulse. With a waveform analysis conclusions about the properties of the building material can be drawn. In this way both the homogeneity of the building material and defects can be checked

be shown. The momentum or speed depends on the density and elasticity of the building material to be tested

together, which is e.g. a statement regarding quality and

Compressive strength allows.

In a penetrating radar measurement, the internal structure of the device is measured by reflection of electromagnetic radiation at impurities. As a rule, very short electromagnetic pulses of a few picoseconds to a few nanoseconds in length are introduced into the interior of the component

radiated and the reflection recorded. The propagation of the electromagnetic waves in the interior is dependent on the structures located in the component, which cause reflection, scattering, diffraction and transmission of the irradiated signal. Usually recorded are the duration, the phase and the

Amplitude of the reflected signal.

In eddy current measurement, e.g. generates a changing magnetic field through a coil, which induces eddy currents in a conductive building material. In the measurement, the eddy current density is detected by the magnetic field generated by the eddy current by means of a sensor, which usually also includes the exciter coil. The measured parameters usually include the amplitude and the phase shift to the excitation signal. For their measurement is usually used a second coil in the sensor. Occasionally, other magnetic field sensors, such as GMR sensors (Giant Magnetoresistance - GMR) or so-called SQUIDs (Superconducting Quantum Interference Device - SQUID)

used. In the eddy current test, the effect becomes

exploited that most impurities and damage in an electrically conductive material also have a different electrical conductivity or a different permeability than the actual material.

The measurement of the specific electrical resistance gives

Information about the state of a device such. a reinforced concrete element. The specific resistance is closely related to the probability of corrosion and the

Corrosion rate. Likewise, the specific

Resistance correlate directly with a chloride diffusion rate. In the measurement, a first pair of electrodes is usually brought into contact with the building material. A voltage is applied between the electrodes. Subsequently, the potential difference between a further electrode pair is measured. From this as well as from the arrangement of the electrodes, the specific resistance can be calculated. In the potential field measurement, it can be determined whether a corrosion activity is present, for example, at a reinforcement in the reinforced concrete. In this case, an electrochemical potential between steel and concrete, more precisely between the steel and a set on the concrete half-cell (eg copper / copper sulfate reference electrode) measured at intervals over the entire concrete surface. Anodic and cathodic areas can be determined from the potential field determined in this way. In areas with anodic potential, the steel corrodes or is at least particularly susceptible to corrosion.

In the rebound measurement basically a firing pin is accelerated in the measuring unit, which on the building material

hits and rebounds. The harder the building material is, the further the bolt rebounds. The rebound distance is e.g. displayed on a scale or automatically recorded and is a measure of the rebound energy. From this, a strength of the building material can be read off. With a series of measurements, an internal structure of the building material can be determined due to different compressive strengths.

Of course, the arrangement may comprise several measuring units based on different measuring principles. Likewise, individual measuring units may also comprise measuring devices for a plurality of measuring methods. Of course you can too

Measurement units come into use, which on others

non-destructive measuring principles for the measurement of internal

Structures or an internal state of the device are suitable. However, the present selection of measuring methods has proven to be economically feasible and proven in daily use. In a preferred embodiment of the arrangement, the detection means comprises a particularly mobile receiving unit, which is designed and positioned or positionable at a measuring position before the determination of the measured value, that the determination of the measured value, in particular by the

User on site, by means of the mobile measuring unit by the recording device is photographically and / or cinematically recordable. The receiving unit is preferably mobile and designed as a separate and freely positionable unit.

Advantageously, it is designed such that it can be worn by a user on site; In particular, it can be dimensioned accordingly for this purpose and a

have appropriate weight. In an advantageous

Embodiment is the receiving unit on a helmet

arranged that a user carries on site; this is allowed

at least essentially the inclusion of the field of vision of the

User, in particular while he performs a measurement using the measuring unit. The recording unit is preferably connected via an interface to the base unit or

connectable, whereby the interface can be wired or wireless. Optionally, the receiving unit can also be connected to the measuring unit, with this connection

can be wired or wireless.

The recording unit thereby allows a region of the object in which measured values are recorded, e.g. be determined at different measuring positions, to capture simultaneously with a particular fixed field of view. The field of vision preferably comprises

at least the mobile measuring unit and / or the user on site in determining the measured value and an environment of

Measuring position. For this purpose, the recording unit can be positioned by the user on site in advance of the determination of the measured values. By the recording unit, the determination of the measured values, for example recorded photographically and / or cinematically, it can undoubtedly be demonstrated at a later date at which points of the object which measured values were determined and, where appropriate, by which user on site they were determined.

The recording unit may comprise a buffer memory (buffer memory) which stores recordings for a limited period of time (for example 5 seconds) according to a first-in-first-out (FIFO) principle. That way, everyone can

Measurement time recordings before, during and after the determination of the measured values are stored. The recording time may e.g. automatically triggered by making the measurement with the measuring unit. The receiving unit, e.g. their field of vision, may e.g. as a reference system for the determination of

Serve measuring positions. Likewise, the receiving unit may e.g.

Beacon for determining the position of the measuring units via

Radio waves include.

Preferably, at least one field of view can be detected by the recording unit, which captures at least the user when determining the measured value and an environment of the measuring position. In this way are proportions and a position of the

User on site when making measurements on the recordings recognizable. The receiving unit can for this purpose e.g. a wide-angle or panoramic camera. Of course, with appropriate training, a conventional camera can be used.

The arrangement may comprise a triangulation system. A triangulation system here denotes a system with which, for example, due to e.g. ground- and / or satellite-based

Signals a position of the measuring unit, in particular a Measuring position, can be determined during the measuring process. When

Ground-based triangulation system can e.g. a beacon or an antenna system on site at the object are used. As a satellite-based triangulation system, e.g. a global positioning system such as the freely available GPS are used.

The arrangement, in particular the mobile measuring unit, may alternatively or additionally include a travel recording system with the aid of which the movement of the mobile measuring unit can be determined. The position sensing system may, for example, comprise a wheel which is mounted on a surface of the body during measurement

is rolled along the inspected object. From the rotation of the wheel can be concluded that the movement of the mobile measuring unit. For this purpose, the wheel may include a magnet whose motion is detected inductively.

Of course, the detection means in variants may also include e.g. comprise a laser-projected coordinate network with which a measuring position can be determined.

The arrangement may further comprise a marking unit with which the measuring position can be marked on the object. In this way, the measurement positions can be visibly marked for later reference directly on the object. It is conceivable

for example, applying the mark by means of a separate marking gun (e.g., a paintball gun, as in the art). However, the marking unit is preferably integrated in the measuring unit, so that the measuring position in the

Determination of the measured value can be marked.

The marking may include a color marking or, for example, in the event that the area to be marked does not visually is to be impaired, a fluorescent label, which is visible only in a specific light. The

Marking unit may function in the manner of an inkjet printer. In this way not only the measuring position can be marked, but also additional information such as e.g. Type and time of measurement are noted. The tag data can be identical to the base unit

so that one associated with the object

Data structure and the object itself comprises the same marking information.

The arrangement may further comprise a macro acquisition unit, with which an immediate environment of the measurement position

photographically and / or cinematically recordable. The macro-recording unit is to be distinguished from the above-mentioned recording unit to the effect that the macro-recording unit is provided for receiving a detailed view of the measuring position. The macro image serves to document the condition of the component at the measuring position in detail. For this purpose, the macro recording unit can comprise a camera suitable for macro photography and / or a microscope camera. The macro recording unit is preferably integrated in the measuring unit, so that the immediate surroundings of the measuring position can be recorded when determining the measured value. In this way, it is ensured that the correct measuring position of the macro recording unit in the state during or shortly before or shortly after the measurement

is recorded.

Also alternatively or additionally, the arrangement may comprise an inertial navigation system. With a

Inertial navigation system is, starting from a known starting point, e.g. on the object, a current position per

Integration of data from acceleration sensors can be determined. Such a system generally has a total of six kinematic degrees of freedom, of which three translational and three rotational, which are also based on three mutually orthogonal unit vectors. With this sensor system, the body coordinate system can be determined in real time and via a kinematic transformation with a fixed, previously known, spatial coordinate system

allows.

The inertial navigation system can be integrated in a first variant in the receiving unit of the detection means.

In this way, it can be determined particularly easily in which direction the recordings are taken by the recording unit. In a second variant, the

Inertial navigation but also be integrated into a macro recording unit. As a result, it can be determined particularly easily in which direction the recordings are taken by the macro recording unit. This is particularly advantageous if the macro recording unit is integrated in the mobile measuring unit and the immediate surroundings of the measuring position are recorded.

For repeated determination of a measured value at a selected measuring position, the arrangement may comprise a monitoring unit temporarily or permanently attached to the object, which has an interface for data exchange with further units of the arrangement, in particular the base unit and / or a server to be described in more detail below. The

Monitoring unit may, for example, to perform at least one or more of the following measurements

be trained:

- ultrasonic measurement,

- Radiography, - eddy current measurement,

With regard to the measurements, the monitoring unit

Inspection, an outside of the device are used. However, the monitoring unit does not need to be mobile, and it can basically be applied to input and output

Dispensing means are dispensed with. The monitoring unit may comprise an interface for connection to an external network, so that measurement data without going through the base unit, e.g. directly to a network service unit can be transmitted.

The arrangement, in particular the measuring unit, may further comprise a recording device which comprises at least one

Acceleration value and / or a humidity value and / or a temperature value and / or a specific radiation value preferably together with the measurement time and / or Measurement position detected when at least one predefined threshold of one of these values has been exceeded. By such a recording device possible damage to the measuring unit can be detected, which could affect the measured values. The recording device may be arranged in the measuring unit or in the base unit. For example, a high acceleration of the measuring unit may indicate that the

Unit was accidentally dropped by the user and may therefore no longer provide reliable measurement results. The recording device can thus have the function of a "black box".

The data record which can be transmitted to the base unit and stored there can contain, in addition to the measurement value determined by the measurement unit and the measurement position and / or measurement time detected by the detection means, at least one additional measurement value, such as a strain value and / or a moisture value and / or or a temperature value and / or a specific radiation value and / or an acceleration value and / or a measured value which has been determined by a monitoring unit as described above.

Advantageously, the interface of the base unit is designed for connection to a public or proprietary network, the arrangement comprising a server to which the

Base unit for data exchange via the public or proprietary external network is connected or attachable, the server is accessible to an authorized user via a, preferably public, network. The server can be a concrete implementation of the above

Netwerkserviceeinheit be, with which services over the

Network can be provided or executed. The server is trained to collect data from the

Base unit to receive and save. Similarly, the data from the server can be edited. A server has the advantage over a base unit that the determined data can be made available to third parties independently of the base unit, which are only authorized to access the server but not to the arrangement according to the invention for inspection. Such authorized users may e.g.

Customers of a provider of the arrangement described herein or members of a construction inspection authority, which in this way can access the inspection data first hand. In particular, the authorized users can

Directly track the inspection of the object in a virtual way and, where appropriate, influence it,

for example, by instructions described in more detail below.

Preferably, the server comprises at least one stored data structure which is assigned to the object to be inspected. The server is designed to supplement the data structure with data transmitted by the base unit and to the authorized user, in particular in real time.

provide. The data structure forms one

uniform format for data from different sources. On the one hand, external data about the object, in particular external data on the building, such as Construction plans of the building, historical inspection data and / or technical specifications or

Standard data for the elements, in particular the components, be included in the data structure. On the other hand, the

Data structure from the server with data or records of

Basic unit comprising measured values of the measuring units or

if necessary, the monitoring units are supplemented. Likewise, for example, recordings of the particular mobile recording unit and / or the macro acquisition unit can be integrated into the data structure. The server thus forms a so-called data warehouse ("Data Warehouse"), in which data about the object from different sources, for example, in a single format summarized (information integration) and can be provided. This improves the convenience of accessing the data of the object.

The data structure is preferably such that the authorized user and / or the user locally from the data structure, a virtually accessible three-dimensional model of the object to be inspected, in particular the

inspecting building, can be provided by the server. "Accessible" in this context means that the

authorized users e.g. as a so-called avatar can move in the virtual model largely free. In this case, an on-site user can be simultaneously represented in the same model as an avatar, so that e.g. Interaction between the authorized user and the user on-site via the server is possible, which may result in some sort of "on-site" team meeting

Training e.g. on the base unit and / or on the

Measuring unit and / or on a head-up display, in particular a head-up display of glasses, be presentable, which can carry the user on site or the authorized user.

The data structure and the virtual model based thereon can preferably be continuously enriched by the server with the data transmitted by the base unit to internal structures and / or an internal state of the components of the measurement units. This ensures that the server

provided model is up to date and the Inspection can be monitored by the authorized user in real time.

In this virtual model, a data structure and / or original and / or derived data sets and / or

Measurement instructions and / or recording instructions and / or

Instructions for determining at least one additional measured value are superimposed in real time, so that a "Virtual Augmented

Reality "model is created, for example, the

Measurement positions marked in the virtual model and as a reference (similar to a hyperlink)

be formed so that the desired information about an internal state and / or an internal structure can be retrieved with appropriate action of the user. In the virtual model, the internal structures may e.g. by

semitransparent walls may be visualized, with additional information such as nominal values or computationally simulated values e.g. a corrosion of a reinforcement

can be displayed. In this case, critical measured values for internal defects or defective range, e.g. color

be highlighted.

The server preferably comprises a library of programs with which data records of the data structure that are selectively selected by the authorized user can be prepared and / or retrieved. In this way, on the one hand, for example, three-dimensional views and, on the other hand, object reports, in particular building reports, can be generated from the data structure. On the one hand, the programs of the library allow the relevant relevant data to be extracted from the data structure and, on the other hand, to be prepared in the desired form. Advantageously, an instruction can be transmitted by an authorized user via the server. For example, to the base unit, and optionally from this, to the

Monitoring unit and / or to the mobile measuring unit and / or to the user on site a measurement instruction be transmitted. In particular, if the measuring unit is remotely controllable, the measuring instruction is preferably transmitted directly to the measuring unit. The measurement instruction may e.g. a measurement position and / or a measurement time and / or a type of measurement to be performed by the user on site. The transmission of one or more measurement instructions can be done in real time. Alternatively or additionally, one or more

Messanweisungen but also pre-compiled and the

Users can be made available locally then collected. The measurement instruction or multiple measurement instructions may e.g. prior to inspection on the server in the form of an inspection plan for the user on site. If necessary, the desired measurement positions can be displayed in the virtual model. Preferably, however, the measurement instruction is transmitted in real time to the user in the field, so that e.g. directly influence the inspection by the authorized user

can be taken. The authorized user does not have to be on site for this purpose.

Alternatively or additionally, an instruction for determining at least one additional measured value, for example an expansion value and / or a moisture value and / or a temperature value and / or a specific radiation value and / or an acceleration value determined by an acceleration sensor, can be transmitted to the detection means. Preferably, the transmission of the additional measured value takes place in real time. Also alternatively or additionally, a recording instruction can be transmitted to the particular mobile recording unit and / or to the macro recording unit, preferably in

Real time.

The measurement statement and / or the instruction to determine

At least one additional measured value and / or the recording instruction can contain information on which measuring position the measurement or recording should take place. It is conceivable that the measurement or recording takes place automatically when the predetermined measuring position is reached. The arrangement, in particular the

Measuring unit or the macro-recording unit, may be programmed for this purpose or be that the measurement or recording then takes place automatically.

The server may act as a localized server unit e.g. at a provider of the presently described arrangement for

Construction inspection be trained. However, the server is preferably as dynamically customizable to a need

Information technology infrastructure, in particular as a cloud-based server provided. In this way, the capacity of the server can be easily expanded if necessary. For example, in the case of a particularly large data structure, the server may be due to a high complexity of the object or to special requirements on the part of a server

authorized user to the quality of the visual presentation. If need arises, unnecessary resources can be cheaply rejected.

The delocalized server structure of a cloud-based server also ensures that the data available on the server or that provided by the server

Services remain available, even if individual areas of the server fail. The range of services offered in the context of cloud computing encompasses the entire spectrum of information technology and includes infrastructure such as computing power, storage space,

Platforms and software.

Another aspect of the invention relates to a method for inspecting an object, in particular a building,

in particular for implementation with an arrangement as described herein. The method comprises the steps:

Nondestructive determination of a measured value to an internal structure and / or an internal state of, in particular inaccessible, element of the object, in particular

Structural elements of the structure through a mobile measuring unit,

- Detecting a measuring position at which the measured value

is determined, and / or a measurement time at which the measured value is determined with a detection means,

- In particular, automatic transmission of the of

Measuring unit determined at least together with the measurement position detected by the detection means as a data set via a data interface to a base unit,

- Save the record in the base unit.

The measuring unit can be operated by a user on site. However, it is also conceivable and within the scope of the invention that the measuring unit is remotely controllable and it requires no operation by a user.

The advantages of this method are directly apparent from the arrangement described here for inspecting an object, in particular a building.

The method may further comprise the steps of: - Transmitting a record from the base unit to a server, in particular comprising measured values for an internal structure and / or an internal state of, in particular inaccessible, components, preferably via a

public or proprietary network, wherein the server comprises at least one stored data structure which is assigned to the object to be inspected,

- supplement the data structure with the data set transmitted by the base unit,

Provide, in particular in real time, the data structure, in particular on the server, in particular as a virtually walk-in three-dimensional model of the object to be inspected, for an authorized user and / or a user on site.

Alternatively to the above embodiment, the

Data structure can also be provided on the base unit or a head-up display.

In the non-destructive determination of a measured value to an internal structure and / or an internal state of the

Component is preferably at least one of the above-mentioned measurement method is used. Likewise, the method may include positioning one as particularly mobile

In particular mobile recording unit preferably detects a field of view, which detects at least the user in determining the measured value and an environment of the measuring position. In order to train persons for the use of the arrangement according to the invention and / or the method according to the invention, it may be advantageous to make the server accessible to these persons. The authorization can be limited in time and / or to certain rights. For example, it may be limited to read access, such that, for example, these persons have no right to supplement and / or modify the data structure stored by the server. However, the persons may be entitled to receive data from the server, for example, the object to be inspected as virtual

Further modifications of the method emerge from the arrangement described here for the inspection of an object.

The invention will become more apparent from the illustrations

FIG. 1 shows a block diagram of an inventive device

Arrangement 1 for inspection of a building 2 designed as an object, which includes a server 3. In Fig. 1, the functional units are shown as separate blocks, which may be executed separately in concrete implementations or may be partially combined in one device. The server 3 can serve as a localized server unit, e.g. at a provider of

Arrangement 1 may be formed. The server 3 may also be implemented as a delocalized, cloud-based server 3.

The server 3 comprises a library of different ones

Applications 4, with which stored data or data structures on the server 3, e.g. analyzed, edited and / or managed. As the case may be, e.g. Authorized users 7 themselves create applications 4, e.g. to enable an individualized data processing. In this case, a program library 5 of the server 3 can be accessed, which, e.g. have standardized program routines for two- and / or three-dimensional output of data, text output and / or other data processing.

The server 3 comprises a database 6 in which data can be stored. The data is preferably stored in a predetermined or dynamically adaptable, unified data structure, which has a uniform access to

different types of data. In particular, for example, image files, sound files as well as data files or individual data points in the uniform data structure be summarized. In this case, the data structure can be associated, for example, with a building 2 inspected or to be inspected. In this way, for each building 2 inspected with the arrangement 1, a comprehensive collection of information in a simple and versatile data format can be provided. The data structure preferably has at least data from

three-dimensional blueprints of the associated structure 2. This data may e.g. with historical data of earlier

Enriched inspections. Likewise, e.g. the

processed building materials of the individual components can be stored.

Of course, the server 3 has e.g. Processing units and interfaces for data exchange in order to provide the necessary functionalities. The server 3 is also designed for this purpose or the program library 5 includes corresponding program routines for converting the data stored in the database or the data structure into a visually representable,

depict three-dimensional virtual model 9 of the structure 2. The conversion into the visual representation may e.g. by a client-side application on a personal computer of the

authorized user 7 done. Likewise, the implementation of the visual representation can also be done on the server 3 and as image or movie files to the computer of the authorized

User be transferred.

The virtual model 9 is preferred as walk-in and

implemented interactive virtual model 9. The authorized user 7 or a local user 10 who is involved in the inspection of the building 2 can thus "enter" the virtual model 9. The user can be present as a pure observer in the virtual model 9 or be represented by a so-called avatar. The model 9 can do this Have input options, via which the authorized user 7 and / or the user on site 10 or its

Avatar (s) can interact with the Model 9. For example, excellent digits on virtual model 9 can be considered

activatable references (similar to the links - hyperlinks - a website), which refer to further data. Thereby, e.g. Construction data like type of

used concrete, planned number of reinforcements in the concrete or historical data of past inspections can be called by interaction.

Preferably, data can also be entered via the model 9. In particular, e.g. Excellent locations in the model 9 can be marked by the authorized user or his avatar, to which e.g. 10 measurements should be made by the user on site. The stored data and / or the data structure can or can thus be changed by interaction with the model 9, in particular supplemented.

Further possibilities of such a walk-in

Three-dimensional virtual model 9 of the structure 2 to be inspected are directly accessible, in particular in the

Connection with a test arrangement 11, as described below.

The test arrangement 11 comprises at least one base unit 12 and one or more measuring units 13. In addition to the measuring unit 13, the test arrangement 11 can comprise a detection means 14 for the

Detecting a measurement position and / or a measurement time point at which a measurement with the measuring unit 13th

is carried out. Furthermore, a marking unit 15 can be present with which the measuring position of a measurement on the building 2 can be marked. In addition, a macro recording unit 16 may be present, which has a visual interface. It is possible to create a measuring position with its immediate surroundings. The recording preferably takes place shortly before, during and / or shortly after the measurement with the measuring unit 13.

The detection means 14 may comprise a receiving unit which can visually detect a portion of the structure 2 in which measurements are taken together with the user on site 10. Such a receiving unit may also be, e.g. be formed as a further detection means, as a separate receiving unit 17. For example, the detection means 14 may be integrated in the measuring unit 13 and a

Triangulation system include while the separate

Recording unit 17 for additional visual detection of the measurement positions is used. The receiving unit 17 is e.g. described in more detail with reference to FIG. 4.

The measuring unit 13, the detecting means 14, the

Marking unit 15, the macro receiving unit 16 as well

if necessary, the separate receiving unit 17 are for

Data exchange preferably connected via a network to the base unit 12. The data exchange can be automatic and e.g. immediately upon changes to the data structure.

Of course, data can also be stored in the individual units 13 to 17 during the inspection and can only be transferred to the base unit 12 at a later time. The network can be wired or wireless, with either a proprietary or public network being used.

The base unit 12 is connected to the server 3 via another or the same network. The data of the units 13 to 17 are thus via the base unit 12 to the server. 3

transferable. The server 3 complements the building 2 associated Data structure with the transmitted data. The additions can, for example, be transferred to the data structure in real time. Likewise, the virtual model 9 generated from the data structure can be provided with the additions in real time. In this way, a user 7 or 10 can be informed in real time, for example, about a measurement made. Of course, for example, data can also be transmitted to the measuring unit 13 by the server 3 via the bass unit 12, for example. Such data may eg be generated by an authorized user 7

Measuring instruction, which the user on site 10 on a display of the base unit 12 and / or the measuring unit 13th

are displayed.

An example flow is as follows:

The local user 10 performs the measurement as a result of the measurement instruction, using e.g. is detected by the receiving unit 17. The data thus obtained - e.g. Measured values of the measuring unit 13, measuring positions detected by the detecting means 14,

Overview shots of the recording unit 17 with the user on site 10 when performing the measurement and / or macro shooting of the macro-recording unit 16 - can to the server. 3

be transmitted. This complements the data structure and creates a supplemented virtual model 9 if necessary

authorized user 7 can thus access the supplemented data and store it e.g. for quality and / or completeness.

The test arrangement 11 can also be at least one

Monitoring unit 18 include, which is for example fixed to the structure 2. The monitoring unit 18 is connected to the server 3 and / or the base unit 12. The monitoring unit 18, like the measuring unit 13, can measure measured values of components of the Include building 2. In contrast to the measuring unit 13, however, the monitoring unit 18 is designed in this embodiment as a stationary unit for the continuous transmission of measured values.

FIG. 2 shows exemplary embodiments of the base unit 12 and of a detection means embodied as a separate receiving unit 17 and of a measuring unit 13. The measuring unit 13 will be described below by way of example on the basis of a rebar testing apparatus based on an eddy current technology.

The base unit 12 has a screen 20, which in the present case is touch-sensitive for inputting data

is trained. The base unit 12 has a protective housing 21 with a cover 22 with which the screen 20 can be protected. In addition, means 23 for positioning the base unit 12 in a desired position can be formed on the protective housing 21. The base unit 12 may be substantially like a rugged laptop or tablet computer as it is used in the field. The

Base unit 12 may also include a keypad 24 with which inputs may be made.

The measuring unit 13 has a not recognizable here

Measuring device, which are designed to carry out the respectively used for measuring method. In the present case, these are exemplary coils for carrying out a

Eddy current based reinforcement testing in e.g. Reinforced concrete. The measuring unit 13 includes a likewise touch-sensitive screen 26 for displaying and inputting data.

Further, the measuring unit 13 includes four wheels 25, which during measurement on a surface of the inspected object can be rolled along. One of the wheels 25 contains a magnet, which can not be recognized here, whose movement can be detected inductively. In this way, the trajectory along which the measuring unit 13 is guided over the surface of the object can be determined particularly precisely.

The receiving unit 17 has a camera 27, which has a comparatively large field of view, so that a region of the building 2 can be detected in an overview view 35

(see, e.g., Fig. 4). If necessary, the camera 27 may include a wide-angle lens or a fish-eye. The camera 27 can also be designed as a panoramic camera.

FIG. 3 shows schematically how a user can make a measurement on site 10. With the help of a mobile

Measuring unit 13, he can determine a measured value of the object 2. This measured value is influenced by a defect 42 and can thus provide information about the presence of the defect 42. The measuring unit 13 is connected via an interface to

Data exchange with a base unit 12 connected, in which of the measuring unit 13 transmitted data records can be stored. The base unit 12 also has an interface to the

Data exchange with a proprietary or public

Network 3 on. Alternatively, the interface of the

Base unit 12 also for direct data exchange with a

Server be trained. At the measuring unit 13, a macro recording unit is arranged in the form of a camera 16, with the help of which the exact measuring position can be recorded. Another camera 44 arranged on the helmet of the user 10 essentially captures the field of view of the user 10 on site. The field of vision of another camera 17 captures the user on site 10 during the measurement. At object 2 is a

Monitor unit 18 attached, for example, as Moisture sensor or can be configured as a temperature sensor. The monitoring unit 18 also has an interface for exchanging data with the network 3.

Figure 4 shows a view 30, e.g. with a

Program routine of the program library 5 from the building 2 associated data structure or from the virtual model 9 can be generated. The view 30 shows a two-dimensional

Top view of a portion of the structure 2. In the view 30 are a desired position and a desired

Of course, view 30 may also show a situation of this area after measurement, with the marked measurement positions 32 in this case e.g. may be formed as activatable references via which e.g. the measured values of the measurements can be accessed.
