Description

[0001] The present invention relates to a method for monitoring a rising speed of a filling material according to patent claim 1, a sensor device according to patent claim 9, a computer program product according to patent claim 13, a computer-readable medium according to patent claim 14 and a sensor control system comprising the sensor device according to patent claim 15. Technological background

[0002] The construction industry is under enormous time pressure to complete buildings and requires ever faster manufacturing processes with which a structure can be constructed. One tried and tested method is to set up formwork and fill the formwork with the building substance. A formwork comprises many individual components, for example several formwork walls, which are mounted next to and on top of each other, adjacent to and opposite each other, and which, when joined together, typically form the formwork. The fill material, also known as the building substance, for example fresh concrete, is then poured into the formwork opening. Typically, a formwork is filled with the fill material in sections at different times, so that several layers of fill material are arranged one above the other in the formwork. After a certain amount of time, the formwork only needs to be dismantled so that the finished building components orBuilding walls and ceilings remain. Increasingly higher and more massive formwork is being used. The higher and more complex the formwork, the more difficult it becomes to ensure a reasonable quality of the building components.

[0003] DE 10 2019 108 781 A1 is known from the prior art. This discloses a computer-assisted method and a device for the optimized control of the delivery rate of a concrete pump for filling a formwork arrangement with a pumpable filler compound. A permissible rate of ascent for filling the formwork arrangement with the filler compound is determined based on material and environmental parameters, the static filler pressure is measured, and a permissible delivery rate of the concrete pump is calculated based on the determined permissible rate of ascent and the measured static filler pressure at the formwork arrangement. A similar device is disclosed in FR 27 20 826 A1.

[0004] A disadvantage of these known solutions is that the pressure sensors for measuring the static fill pressure are only mounted at individual points in the formwork arrangement, making the measurement of the static fill pressure very inaccurate. Furthermore, for large-area components in the formwork arrangements, a large number of pressure sensors are required, making pressure data acquisition complex.

[0005] JP 2013 019 202 A is known from the prior art. It discloses a method for measuring the height distribution during road concreting. Laser distance measuring devices are used to measure the concrete height of the road to be concreted, and the measured data is transmitted to a display device. In the method, a previously poured concrete height is compared with a current concrete height, and various concrete heights on the road are displayed on a display device with color-coded animations.

[0006] The disadvantage of this known solution is that it requires complex three-dimensional parameterization of the road volume to be concreted to avoid unevenness in the road surface. Furthermore, multiple laser distance measuring devices are required, making the measuring system very expensive.

[0007] JP 2018 059 329 A is known from the prior art. It discloses a method for determining the height during concrete pouring using reference points and a communication device arranged on the pouring tool. Additionally, coordinates are determined using GPS or laser distance measurements and compared with the reference points. This is intended to accelerate the concrete pouring process and collect data on the concrete pouring. A similar method is disclosed in JP 2009 083353 A.

[0008] The disadvantage of these known solutions is that no information about the concrete quality is incorporated into the filling process during concrete pouring.

[0009] CN 114 151 299 A is known from the prior art. It discloses a speed control system for a concrete pump for steel shells, comprising a concrete pump, a pump PLC for controlling the concrete pump, a laser rangefinder, a PC control terminal, a communication interaction unit, and a PLC main control unit. The laser rangefinder detects the height difference between the concrete liquid level and the laser rangefinder during the monitoring process and transmits information to the PLC main control unit. The PLC main control unit controls the pumping speed of the concrete pump according to the height difference.Through the cooperation of the concrete delivery pump, the delivery pump PLC unit used to control the concrete delivery pump, the laser rangefinder and the PLC main control unit, the height information of the concrete liquid level can be fed back through the laser rangefinder, the pumping speed can be adjusted according to the height information, precise speed changes can be made in different pouring sections, precise speed control is achieved in the whole pouring process and the pouring speed is controlled. Description of the invention

[0010] An object of the invention is to avoid at least one of the disadvantages of the prior art, and in particular to provide an improved method for monitoring the rise rate of a fill material in a formwork, so that quality defects in the building structure can be identified as soon as the fill material is being poured in. Furthermore, an improved sensor device for monitoring the rise rate, an improved computer program product, a computer-readable medium, and an improved sensor control system are to be created, which enable quality defects in the building structure to be identified as soon as the fill material is being poured in.

[0011] This problem is solved by the features of the independent patent claims. Advantageous further developments are set forth in the figures and in the dependent patent claims.

[0012] A method according to the invention for monitoring a rising speed of a filling material in a vertically fillable formwork with at least one optical sensor device and at least one computing device comprises at least the following steps: a) Providing at least one limit value for the rate of rise of the filling material in the at least one computing device, wherein the at least one limit value is based at least on one parameter of the ambient conditions, in particular the air temperature, a reference temperature and / or an installation temperature; b) Providing at least one measuring interval for an optical measurement with the optical sensor device in the at least one computing device, wherein in particular the at least one measuring interval is dependent on consistency information of the filling material; c) Filling the formwork with the filling material; d) Carrying out optical measurements with the at least one optical sensor device for at least one current fill layer height of the filling material in the formwork during the filling of the formwork with the filling material;e) Calculating the current rate of rise of the filling material when filling the formwork with the filling material at least with the aid of the measured values ​​of the optical measurements of the at least one current fill layer height, the at least one parameter of the ambient conditions, and at least one time measurement in the at least one measuring interval in the at least one computing device, wherein a time stamp is set for this purpose in the at least one computing device or a time measuring device is used to determine the time measurement;; f) Outputting at least one warning signal when the at least one current rate of rise of the filling material reaches the at least one provided limit value of the rate of rise of the filling material.

[0013] Exceeding the limit value for the rate of rise or filling the formwork too quickly will result in excessive formwork deformation and the specified formwork evenness will no longer be maintained. If the limit value for the rate of rise is exceeded, defects in the structural fabric of the completed building can be expected. At least the location and time of the potential defect can now be identified at a fill layer height, making subsequent inspection of the structural fabric easier. If the current rate of rise is below the limit value, this prevents construction and element joints between the formwork components from opening and thus causing the formwork to fail. Failure of the components would endanger the safety of the workers on the construction site.By issuing at least one warning signal, workers on the construction site are warned early in real time. This means that if the limit value for the current rate of ascent is exceeded, workers can react quickly and take action directly on the construction site before the formwork is damaged. The fill material can be poured into the formwork from above through a formwork opening, or it can be pressed into the formwork through an opening in a component of the formwork. It is essential to know the consistency information of the fill material, such as the consistency class, and to take this into account directly during the filling process. This increases the quality of the surface of the building structure immediately after completion of the structure and significantly improves occupational safety.Reworking the surfaces of the building wall is no longer necessary, as improved color uniformity, flatness, and uniformity of the building wall is guaranteed. Workers can rely on at least one warning signal, thus reducing stress on the construction site. To prevent the errors described above, including all their adverse consequences, the method presented here monitors compliance with the current rate of ascent during the filling process, thereby increasing occupational safety and the quality of the surfaces of the building components, i.e., the building walls and ceilings. This method enables the formwork to be filled with fill material with millimeter accuracy. Furthermore, follow-up costs are minimized by avoiding expensive improvements to the building.

[0014] In particular, the filling material is fresh concrete. The consistency of fresh concrete is a measure of its stiffness and defines its workability. The consistency is divided into slump classes and compaction classes, which are measured by the slump test and, for stiffer consistencies, the Walz compaction test. The slump test can be carried out according to the DIN 12350-5 Testing of fresh concrete be defined and the compaction test can be carried out according to the DIN EN 12350-4 Testing of fresh concretebe defined. The consistency classes range from stiff to plastic, soft, very soft, flowable to very flowable consistency class for fresh concrete. Particularly in the production process of exposed concrete components, excessively rapid concreting and uneven fill layer heights or fresh concrete layer heights reduce the quality of the exposed concrete surface. The resulting defects, for example with regard to the color uniformity or surface texture of the exposed concrete layers, subsequently require costly repair. The method described above identifies the defects and prevents subsequent repair of the surfaces. Alternative fill materials are mortar, screed, or asphalt, although their consistency information may differ from that of fresh concrete. The consistency of these fill materials is also a measure of the stiffness of the fill material and defines its workability.

[0015] The type of formwork can be crucial during filling. A vertically fillable formwork can also accommodate inclined and / or curved components, allowing the surfaces of the building components or building walls to be predefined during construction. Depending on the component, a permissible formwork pressure, for example, from literature, can be used for the formwork.

[0016] Using the optical measurements of the at least one optical sensor device regarding the current level of the pile, a time measurement of the change in the current level of the pile can be determined, either directly or indirectly, in order to monitor the provided measurement interval. Thus, a time stamp is set in the at least one computing device in order to determine the current rate of ascent with high precision and in real time. Alternatively or additionally, a time measurement device can be used to determine the time measurement, thus providing a redundant measuring device to further improve the time measurement and thus improve the accuracy in calculating the current rate of ascent.

[0017] It is advantageous to calculate the current rate of climb using the measured values ​​from the optical measurements, using the mean or median of the last 5 to 20 measured values. This enables a reliable calculation of the current rate of climb, improving comparison with the provided limit value. The measured values, at least from the optical measurement, can be assigned to a specific component, allowing the formwork component to be easily parameterized. Alternatively, a mathematical filter, such as a Kalman filter, is used to calculate the current rate of climb; this filter is used to estimate the measured values ​​from the optical measurement. This allows system variables that are not directly measured or measurable to be estimated, while the errors in the optical measurements are optimally reduced.

[0018] In particular, various predefined bandwidths are used in the calculation of the current climb rate to eliminate outliers in the measured values. This significantly improves the calculation, preventing unnecessary warnings with at least one warning signal.

[0019] The provided limit value for the rate of rise can either be entered manually into the at least one computing device or determined based on individual parameters. These parameters include, but are not limited to, a raw density of the fill material, a consistency class of the fill material, a fill material temperature (e.g. fresh concrete temperature), an air temperature, a setting time, a type of compaction of the fill material, a reference temperature, an end of setting at the reference temperature, an installation temperature, a type of formwork, a surface quality of the formwork skin, possible exposed concrete requirements such as color, a height of the component in the formwork, and a composition of the fill material. If these parameters are not available, a fixed, defined limit value is used in the at least one computing device. This limit value can vary depending on the component of the formwork or the type of concrete.The height of the filling layer must be stored in a table in at least one computing device and is therefore immediately available.

[0020] The at least one measuring interval can be entered manually into the at least one computing device or determined based on the consistency class of the filling material. Alternatively or additionally, the at least one measuring interval is determined based on the number of optical sensor devices on the component to be filled. If the at least one measuring interval is missing, the at least one computing device can set a predetermined value for the at least one measuring interval. The at least one measuring interval is, in particular, between 0 and 50 seconds. This provides a proven filling quantity in the formwork so that a sufficient final fill layer height is achieved.

[0021] In particular, multiple measurement intervals are provided, which are controlled depending on the consistency information of the filling material. Furthermore, the multiple measurement intervals can be maintained dynamically and stored in the at least one computing device, with the multiple measurement intervals being extended or shortened depending on the properties of the filling material. This takes dynamic processes in the filling process into account. This can mean that the duration of the at least one measurement interval or the multiple measurement intervals increases if no filling material is poured into the formwork.

[0022] Preferably, the optical measurements comprise a current distance from the at least one current filling layer height of the filling material in the formwork to the at least one optical sensor device during the filling of the filling material. This makes it easy to determine the current rate of ascent. Furthermore, it can be taken into account that, in the event of an error message from the optical sensor device, a further optical measurement of the current distance from the at least one current filling layer height of the filling material in the formwork to the at least one optical sensor device is immediately performed during the filling of the filling material, so that error dependency in the method described here is minimized.

[0023] In particular, a sudden increase in the current climbing speed, which may be caused, for example, by incorrect measurements with the at least one optical sensor device, is computationally compensated in the at least one computing device. This allows, for example, a filler material bulge to be detected if it occurs when filling the formwork with the filler material. This prevents the unnecessary output of at least one warning signal.

[0024] In addition, in particular depending on the type of formwork or the components of the formwork, individually predefined fill level limit heights are set in at least one component and made available in the at least one computing device for the at least one component. This allows the at least one component to be parameterized and the filling with the fill material to be controlled more effectively. In particular, the at least one component of the formwork has several predefined fill level limit heights. This allows the at least one component to be matched to the fill material during filling and a fill level limit height suitable for the fill material to be predefined. A fill level limit height can depend on the consistency information of the fill material, so that different fill level limit heights exist in the component depending on the fill material used.During filling, multiple fill level limit heights can be assigned to the at least one component, with a different current rise rate being permitted depending on the fill level limit height. Accordingly, each fill level limit height in the at least one component can have its own predefined rise rate limit. The predefined fill level limit heights can be stored, for example, in a table in a memory device.

[0025] In particular, the at least one measurement interval correlates with at least one predefined fill layer limit height in the at least one component. This makes the entire process highly dynamic and particularly suitable for highly efficient formwork filling, providing increased occupational safety and significantly improving the quality of the building structure.

[0026] Preferably, the current climb rate is calculated interval-related. The at least one computing device calculates the current climb rate for the at least one measuring interval, so that, if several measuring intervals are arranged one above the other, each measuring interval can be individually monitored and an individual warning signal can be issued.

[0027] Alternatively or additionally, the current rate of ascent is calculated on average. At least one computing device calculates the current rate of ascent on average over several measurement intervals, so that the total load, for example, the total pressure load, on the formwork can be determined.

[0028] Preferably, at least one first parameter of the formwork is provided prior to step a), which can be taken into account in the calculation of the current climbing speed. This improves the calculation of the current climbing speed in the provided formwork.

[0029] In particular, at least one formwork height is provided. The height of the formwork or the height of a formwork component can be an important parameter for calculating the climbing rate, since higher components have different predefined limit values ​​than lower components.

[0030] Alternatively or additionally, at least one material parameter of the fill material is provided. The at least one first parameter may include, but is not limited to, at least one parameter from the bulk density of the fill material, a consistency class, a fill material temperature (e.g., fresh concrete temperature), a setting time, a type of compaction of the fill material, a setting end at a reference temperature, possible exposed concrete requirements, or a composition of the fill material (e.g., concrete composition).

[0031] Alternatively or additionally, at least one further parameter can be provided which can be taken into account in the calculation of a maximum permissible rise rate. The at least one further parameter can include, but is not limited to, at least one parameter from an air temperature, a reference temperature, an installation temperature, a type of formwork or a surface condition of the formwork skin. The ambient conditions can therefore also contribute to the calculation of the maximum rise rate of the filling material. In particular, the at least one limit value provided is based on at least one further parameter. The maximum permissible rise rate depends on the filling boundary conditions during the filling process. The value of the current rise rate can depend on the shape of the formwork and the filling quantity of the filling material.The current climb rate should not reach the maximum climb rate, with the provided limit value being defined such that the current climb rate value is always below the maximum climb rate value. Furthermore, the provided limit value can be sufficiently far away from the maximum climb rate value so that the current climb rate never reaches the maximum climb rate value.

[0032] Preferably, a fill layer height development is calculated. The fill layer height development comprises the temporal progression of the current fill layer height in the formwork, with particular consideration given to the multiple measurement intervals. This allows for improved monitoring of the overall load in the formwork, allowing a forecast of the filling process and increased occupational safety.

[0033] In particular, the development of the fill layer height is assigned to at least one structural component. This allows a historical schedule for the construction of the structural components to be created, ensuring sufficiently detailed documentation. The number of individual schedules for each structural component results in comprehensive documentation of the construction of the structure. This allows, after the construction has been completed, the rise rate used for each structural component and for each fill layer within the component to be verified. The individual schedules can be stored on a storage medium or storage device for reusable use.

[0034] In particular, the fill layer height development is assigned to at least one component of the formwork. This allows a historical schedule for filling the formwork with the fill material to be created, ensuring sufficiently detailed documentation. The number of individual schedules for each formwork provides comprehensive documentation of the filling of all formwork in the structure. The individual schedules can be stored on a storage medium or storage device for reuse.

[0035] Preferably, the compaction phase of the fill material is determined. A compaction phase during the filling process may be necessary to ensure sufficient compaction of the fill material. Typically, a vibrating device is inserted into the fill material to enable compaction of the fill material through vibration. During the compaction phase, it may be advisable not to add new fill material to the formwork. Detecting the compaction phase improves the quality of the structure, as otherwise defects in the building fabric may occur due to air pockets in the building fabric.

[0036] Alternatively or additionally, the degree of compaction of the fill material is determined. During compaction, for example, air bubbles are released in the fill material, causing the fill material to adhere more tightly to one another. Determining the degree of compaction in a single layer allows for the optimization of the time required to fill the formwork with the fill material, thus reducing the compaction phases and completing the filling process quickly without causing any quality defects in the building structure.

[0037] Preferably, at least one temperature is measured on the formwork. The temperature on the formwork can affect the maximum rise rate of the fill material, so measuring it and then incorporating the temperature measurement into the calculation improves the accuracy of the calculation of the maximum rise rate. The surface temperature of the fill material, the surface temperature of the inside of the formwork, i.e. the formwork skin, or the surface temperature on the outside of the formwork can be used individually or in combination with several measurements. The more temperature parameters are measured and included in the calculation, the more accurately the maximum rise rate of the fill material can be calculated, so that the workers on the construction site are warned, if necessary in real time, using at least one warning signal.

[0038] Alternatively or additionally, at least the ambient humidity is measured. Ambient humidity can affect the maximum rise rate of the fill material, so measuring it and then incorporating the humidity measurement into the calculation improves the accuracy of the calculated current rise rate.

[0039] Alternatively or additionally, the ambient temperature is measured. The ambient temperature can affect the maximum rise rate of the fill material, so measuring it and then incorporating the temperature measurement into the calculation further improves the accuracy of the calculated actual rise rate.

[0040] Preferably, an interruption in filling is identified using at least some of the measured values ​​from the optical measurements. The measured values ​​from the optical measurements indicate an unchanged current fill layer height across multiple measuring points, thus concluding that filling has been interrupted. The interruption in filling can be triggered, for example, by a failure of the conveying means for conveying the filling material or a shortage of the filling material for the conveying means. These measured values ​​can be processed in the at least one computing device and output as a further warning signal.

[0041] Preferably, at least measured values ​​from the optical measurements are transmitted to an electronic terminal. The electronic terminal can comprise at least one computing device to process the measured values ​​and at least calculate the current climb rate. Furthermore, error messages relating to the optical sensor device or incorrect measurements from the optical measurements can be processed in the at least one computing device and displayed on the electronic terminal.

[0042] In particular, at least measured values ​​from the optical measurement are output to an output device on the electronic device. This gives the electronic device direct access to the measured values ​​and allows it to process or store them in real time and transmit the measured values, for example, to a worker.

[0043] The electronic terminal advantageously comprises at least one computing device and a storage device for calculating the current rate of rise of the filling material. This allows the calculations to be carried out at a distance from the at least one sensor device. Further advantageously, the electronic terminal is a portable device, such as a laptop or a tablet, so that it can be easily moved by the user on the construction site. The at least one computing device can have a software application (app) that controls the sensor device, thus providing a compact and simple solution that can be easily implemented on the construction site. Advantageously, the electronic terminal has an output device with which the at least one warning signal is output.Having at least one warning signal allows for rapid action, which on the one hand increases work safety and also improves the quality of the concrete surfaces.

[0044] In particular, the electronic terminal is designed as a mobile phone, such as a smartphone. Typical mobile devices have an app store, so that the app can be easily downloaded from the app store and easily installed on the mobile phone, thus making it easily available to the user on the construction site. The mobile phone then has the software application (app). Advantageously, the at least one optical sensor device is connected to a control device. The mobile phone is connected to the control device for exchanging data, wherein the app controls the at least one optical sensor device using the control device. Controlling the sensor device via an app on a mobile phone represents a highly practical element of the described system.For example, the app can first query the height of the formwork and the consistency information of the fill material, then automatically control the sensor device for determining the fill layer height on the formwork, and sends the command to continuously measure the distance from the at least one current fill layer height of the fill material, or the floor in the formwork, to the at least one optical sensor device. The at least one measurement interval specified using the app is based on the consistency information. In addition, the app can transmit the measured values ​​to a documentation platform via a mobile network, where they can be processed accordingly with regard to documentation requirements. The mobile phone thus represents a compact link with simultaneous data processing between the optical sensor device and a documentation platform.

[0045] In particular, the limit value for the climbing speed can either be provided manually in the app or specified based on the initial parameters described above or additional parameters that are requested when creating a new virtual component in the app. The virtual component in the app then corresponds to the real component in the formwork. After implementation, a new component can be easily selected in the app, so that individual parameters for the new component are already available to the user.

[0046] In particular, the multiple measurement intervals are adjusted depending on the consistency information of the filling material in the app. The current rate of ascent can be taken into account, enabling a dynamic filling process.

[0047] Alternatively or additionally, at least the measured values ​​from the optical measurements and at least one measurement interval are transmitted to a storage device. This allows the filling of the formwork with the filling material to be documented and subsequently traced.

[0048] In particular, at least the measured values ​​from the optical measurements are transmitted to a cloud. This ensures that at least the measured values ​​are accessible to multiple people and stored securely. In particular, at least the measured values ​​are stored using a checksum or blockchain technology, ensuring that at least the measured values ​​are stored decentrally and tamper-proof.

[0049] In particular, at least the measured values ​​from the optical measurements are transmitted to a server so that at least the measured values ​​are stored centrally and securely.

[0050] Preferably, a filling system for filling the formwork with the filling material is controlled when the at least one current rate of rise of the filling material reaches the at least one provided limit value of the rate of rise of the filling material. The filling system comprises at least one conveyor for conveying the filling material and for determining the filling quantity of the filling material. The at least one computing device or the app can be connected to the control device of the filling system so that, if the limit value is imminently exceeded, easy intervention is possible and the filling quantity of the filling material can be easily reduced. In particular, the at least one computing device or the app can include a safety level query so that the conveying capacity of the conveyor can be throttled based on the safety level query.For example, a safety level query includes the current climbing speed, with the conveying capacity of the conveyor being reduced to at least 90% of the current conveying capacity. The safety level can be variably set in the at least one computing device or the app.

[0051] The method according to the invention is preferably a computer-implemented method that is executed on the at least one computing device or in the app. Command data is generated in the at least one computing device or in the app and sent to the control device, wherein the control device causes an output device to output at least the at least one warning signal to the output device when the at least one current rate of rise of the fill material reaches the at least one provided limit value of the rate of rise of the fill material. Thus, the method described here is easy to implement, and the optical sensor device is adjustable and controllable.The described methods can thus also be used on multiple different end devices, where, for example, multiple workers or users have access to a portable end device to access the measured values, measurement data, calculated data, command data, and / or parameters and receive these acoustically and / or visually using at least one warning signal on the portable end device. In particular, this creates a network of end devices and computing devices or apps that communicate with each other to exchange the measured values, measurement data, calculated data, command data, and / or parameters.

[0052] Advantageously, the command data is used to graphically display the development of the fill layer height on a display of the output device. Advantageously, the command data is used to display the current rate of ascent on the display at intervals, and in particular, to display it as an average. This allows these parameters to be easily monitored in real time.

[0053] It is advantageous to display the calculated current climbing rates for each pile height graphically. This allows for simplified visualization and quick comparison of different pile heights. For example, the climbing rate limit is graphically displayed in a diagram and compared with the calculated climbing rates for each pile height. The diagram is then displayed on the output device. This allows the user to see at a glance which climbing rates were above and below the maximum permitted climbing rate.

[0054] It is advantageous to display at least parts of the measured data, individual parameters, and calculated data using a dashboard view on the display device. In addition to tabular and graphical display formats, dashboards are available. The dashboards provide a quick overview of highly relevant measured values ​​and calculations from the aforementioned process. For example, the interval-related and average current climbing speed can be displayed as dashboard views, making them easy to read and understandable for employees.

[0055] In particular, several optical sensor devices are provided, which are connected to the at least one computing device or to the app, so that the previously described method can be carried out at multiple positions on the formwork and the formwork can be monitored more effectively. This further improves occupational safety on the construction site and facilitates the identification of quality defects during the filling material filling process.

[0056] A sensor device according to the invention for monitoring a rising speed of a filling material comprises at least a first optical sensor and a fastening device for fastening at least the first optical sensor to a formwork, so that at least the first optical sensor can be positioned above a formwork opening.The optical sensor device is connected to at least one computing device, wherein the at least one computing device is designed to calculate the current rate of rise of the filling material when filling the formwork with the filling material at least with the aid of the measured values ​​of the optical measurements of the at least one current fill layer height, at least one parameter of the ambient conditions, in particular the air temperature, a reference temperature and / or an installation temperature, and based on a time stamp of at least one time measurement in at least one measuring interval or a time measuring device for determining the time measurement, wherein at least one limit value for the current rate of rise (vB) of the filling material is provided in the at least one computing device (41), wherein the at least one limit value is based on the at least one parameter of the ambient conditions.Together with the optical measurements of the current level of the pile from the first optical sensor, a time measurement of the change in the pile height can be determined simultaneously, either directly or indirectly, to monitor the provided measurement interval. Thus, a time stamp can be set in the at least one computing device to determine the current rate of ascent with high precision and in real time. Alternatively or additionally, a time measurement device can be used to determine the time measurement, thus providing a redundant measuring device to further improve the time measurement and thus improve the accuracy in calculating the current rate of ascent.

[0057] The at least one optical sensor is in particular a laser distance sensor, so that the fill layer height can be measured without contact. The laser sends a laser beam through the formwork opening into the formwork and down to the bottom of the formwork when there is no fill material in the formwork. When the formwork is filled with fill material, the laser only reaches approximately to the surface of the fill material, with the laser's range shortening further as the fill layer height in the formwork increases. The laser thus measures the distance from the at least one current fill layer height of the fill material in the formwork to the at least one optical sensor device during the filling of the fill material.

[0058] Advantageously, a camera is provided, which is arranged on the optical sensor device or is part of the optical sensor device. The camera visually records the current fill level, creating images of the current fill level. Such images can be transmitted wirelessly from the camera, for example via Bluetooth LE ®<, or using a data cable, to the at least one computing device or the app, and subsequently to a display device, and thus made available to a user or worker in real time.

[0059] Preferably, at least one vibration sensor is present. The vibration sensor can detect a compaction phase during the filling process and also detect external forces acting on the optical sensor device. For this purpose, the vibration sensor is connected to the control device or to the at least one computing device for exchanging vibration data, so that the control device can control the at least one optical sensor using command data based on the vibration data. This allows the measurement behavior of the at least one optical sensor to be optimized.

[0060] Alternatively or additionally, at least one vibration sensor is provided, which easily detects the vibrations of the optical sensor device and / or vibration of the formwork. The at least one vibration sensor can be connected to the at least one computing device for data exchange. Based on the vibration data collected, conclusions can be drawn about the degree of compaction in the filling material. In particular, the at least one vibration sensor is an acceleration sensor, which can detect vibrations particularly easily.

[0061] In particular, the vibration sensor determines at least one position parameter of the optical sensor device. This allows the inclination or orientation of at least the first sensor to be determined, so that the distance from the at least one current filling layer height of the fill material in the formwork to the at least one optical sensor device can be reliably determined during the filling of the fill material. For example, this makes it possible to determine whether external environmental influences, such as wind, are causing the optical sensor device to vibrate.

[0062] Alternatively or additionally, at least one microphone is provided to measure airborne or structure-borne sound on at least one component of the formwork. The at least one microphone can be connected to the at least one computer for data exchange. Based on the recorded sound waves, conclusions can be drawn about the degree of compaction and the current compressive load on the formwork.

[0063] In particular, an AI module is provided so that the measured values ​​at least from the vibration sensor, and in particular from the microphone, can be evaluated using artificial intelligence (AI). The AI ​​module is at least configured to determine a degree of compaction in the filling material. The AI ​​module can comprise at least one neural network as a computing unit or a support vector machine or a transformer computing unit.

[0064] Alternatively or additionally, at least one temperature sensor is provided, which is connected to the at least one computing device. The at least one temperature sensor measures the temperature at the formwork. The temperature at the formwork can affect the maximum rise rate of the filling material, so that measuring and subsequently incorporating the temperature measurement into the calculation improves the accuracy of the calculation of the maximum rise rate. The surface temperature of the filling material, the surface temperature of the formwork skin, or the surface temperature on the outside of the formwork (for example, on the reinforcement) can be used individually or in combination with several measurements to calculate the maximum rise rate.The more temperature parameters are measured and included in the calculation, the more accurately the maximum rise rate of the fill material can be calculated, so that workers on site can be warned in real time, if necessary, via at least one warning signal. Furthermore, this can ensure that a uniform color scheme is maintained throughout the finished structure.

[0065] Alternatively or additionally, at least one further temperature sensor is provided, which is connected to the at least one computing device. The at least one further temperature sensor measures the ambient temperature. The ambient temperature can affect the maximum rise rate of the filling material, so that measuring and subsequently incorporating the temperature measurement into the calculation further improves the accuracy of the calculation of the current rise rate. Measuring the ambient temperature can also provide information about the temperature of the filling material before filling the formwork, thus allowing for a more accurate calculation of the current rise rate.

[0066] Alternatively or additionally, at least one humidity sensor is provided, which is connected to the at least one computing device. The at least one humidity sensor measures the ambient humidity. The ambient humidity can affect the maximum rise rate of the filling material, so measuring and subsequently incorporating the humidity measurement into the calculation improves the accuracy of the calculation of the current rise rate.

[0067] Preferably, a control device is provided which is connected to the at least one computing device and which is connected to at least the at least one first optical sensor for exchanging sensor data and command data. The at least one optical sensor can be easily controlled with the control device, as described herein.

[0068] Preferably, the at least one computing device is configured to calculate a maximum climbing speed based on the measured values ​​from at least one of the aforementioned sensors. This ensures that the formwork is filled as quickly as possible, ensuring occupational safety on the construction site and sufficient quality of the building wall.

[0069] In particular, a storage device is provided, which is connected to the at least one computing device via data lines or wirelessly for the exchange of data. The storage device can comprise a server and a cloud where the measured values, measurement data, command data, parameters, or calculated data can be securely stored centrally or decentrally.

[0070] Specifically, the control device is a microcontroller. Microcontrollers are typically very small computers mounted on a single chip, forming a completely self-contained system. A microcontroller is a compact integrated circuit designed to control a specific operation in an embedded system. A typical microcontroller includes a processor, memory, and input / output (I / O) peripherals on a single chip. A microcontroller is an on-chip CPU and includes additional peripherals such as memory, ports, timers, etc. This allows the control device to be kept very small, allowing the sensor device to be easily constructed.

[0071] The control device preferably causes an output device to acoustically output the at least one warning signal at the output device, in particular when the at least one current rate of rise of the fill material reaches the at least one provided limit value of the rate of rise of the fill material. This provides an acoustic warning in real time to the persons present on the construction site (workers, users, suppliers, etc.). An output device for the acoustic warning signal can be a horn or a loudspeaker. The acoustic warning signal enables rapid action, thereby improving the quality of the building surfaces. The output device can be arranged on a construction site facility, such as the formwork or a construction site crane, and can output the acoustic warning signal via a loudspeaker or a horn.

[0072] Alternatively or additionally, the control device causes an output device to visually output the at least one warning signal at the output device, in particular when the at least one current rate of rise of the fill material reaches the at least one provided limit value of the rate of rise of the fill material. This provides a real-time visual warning to the persons present on the construction site (workers, users, suppliers). The output device can comprise a display device, wherein the visual warning signal can be a light signal. The visual warning signal can be displayed as a simple flashing warning signal or as a warning element in a graphic. The visual warning signal enables rapid action, thereby improving the quality of the building surfaces.The output device can be arranged on a construction site device, such as on the formwork or on a construction site crane, and output the visual warning signal as a light signal.

[0073] Alternatively or additionally, the output device can also be designed as a vibrating wristband, which is worn on the user's wrist. This allows the user to be directly informed via vibrations when the current climbing rate reaches the specified limit.

[0074] A computer program product according to the invention comprises program instructions configured to execute at least one of the aforementioned methods. The computer program product may comprise instruction data, calculated data, and parameters as described above.

[0075] A computer-readable medium according to the invention comprises at least one computer program product which, when executed by at least one computing device, causes the device to perform at least one of the aforementioned methods. The computer-readable medium can comprise command data, measurement data, calculated data, measured values, and parameters as described above.

[0076] A sensor control system according to the invention comprises at least one sensor device as described above and at least one electrical terminal with a computer program product as described above. The at least one electrical terminal can be a portable electrical terminal, as described above. The sensor control system can also comprise a plurality of electrical terminals, as well as a storage device, as described above.

[0077] The use of the described sensor control system in the construction of buildings leads to a significantly higher quality of the final product because it is possible to react in real time to excessively rapid filling of the formwork or uneven fill layer heights. In this way, the construction company improves occupational safety and subsequently reduces the proportion of costly improvement measures, which in the worst case scenario even involve the demolition of the component and its subsequent re-production. The described process and the sensor control system thus also support the conservation of resources and contribute to the avoidance of unnecessary CO2 emissions. Furthermore, higher quality is delivered with the same worker performance, thus increasing worker satisfaction and making the job more attractive due to the digitalization of the filling process, making it easier to find new workers in the future.This counteracts a shortage of skilled workers in the construction industry.

Implementation of the invention

[0083] The Figures 1 to 3 show a first embodiment of a method according to the invention for monitoring the rising rate of fresh concrete 20 as filling material in a vertically fillable formwork 21 in a sensor control system 25, comprising a plurality of optical sensor devices 30 arranged horizontally along the formwork 20 in the region of the formwork opening 22. Furthermore, a mobile phone 40 is shown, which has a computing device 41 and an app 42. The method comprises at least the following steps: a) Providing at least one limit value GW for the rising rate of the fresh concrete in the computing device 41; b) Providing measuring intervals for optical measurements with the optical sensor devices 30 in the computing device 41, wherein the measuring intervals are dependent on consistency information of the fresh concrete 20; c) Filling the formwork with the fresh concrete 20; d) Carrying out optical measurements with the optical sensor devices 30 for at least one current fill layer height HS of the fresh concrete 20 in the formwork 21 during the filling of the formwork 21 with the fresh concrete 20; e) Calculating the current rising rate v B of the fresh concrete 20 during the filling of the formwork 21 with the fresh concrete 20 at least with the aid of the measured values ​​of the optical measurements of the current fill layer height HS and at least one time measurement t in at least one measuring interval in the computing device 41;f) issuing at least one acoustic and / or visual warning signal WS when the current climbing speed v B of the fresh concrete 20 reaches the at least one provided limit value GW of the climbing speed of the fresh concrete 20. ;

[0084] As consistency information, the user selects the consistency class of fresh concrete 20 in App 42. The consistency of fresh concrete 20 is a measure of the stiffness of fresh concrete 20 and defines its workability. For example, the consistency class for flowable fresh concrete 20 is selected in App 42. As an alternative to fresh concrete 20, App 42 also includes consistency classes for mortar, screed, or asphalt as fill material.

[0085] The limit value GW of the rise rate provided in step a) is set using individual parameters in the app 42 and includes the bulk density of the fresh concrete 20, the consistency class, the fresh concrete temperature, the type of formwork 21, exposed concrete requirements, such as color, the height of the components 23 in the formwork 21, and the composition of the fresh concrete 20.

[0086] The measurement intervals in step b) are determined based on the consistency class of the fresh concrete 20 and the number of optical sensor devices 30 in the component 23 to be filled and entered into the computing device 41. The measurement intervals are between 0 and 50 seconds, thereby determining different fill layer heights HS in the formwork 20, which are arranged one above the other - see Figure 3a. The measurement intervals correlate with predefined fill layer limit heights for each desired fill layer height HS in the components 23 of the formwork 21. This allows the components 23 to be parameterized and the filling with the fresh concrete 20 to be controlled more effectively.During filling, several filling level limit heights can be assigned to a component 23, whereby a different current rate of rise v B is permitted depending on the filling level limit height in the measuring intervals and whereby each filling level limit height in the component 23 has a specified limit value GW of the rate of rise.

[0087] The control devices 35 of the sensor devices 30 are wirelessly connected to the mobile phone 40 for the exchange of sensor data and control data, with the app 42 controlling the optical sensor devices 30 using the control devices 35. The measured values ​​of the optical measurements are transmitted from the control devices 35 to the mobile phone 40 and displayed on an output device, for example, the display 46. The mobile phone 40 also has a storage device 43 in which the sensor data and control data are stored. The app 42 transmits the measured values, control data, measurement intervals, etc. via a mobile network 44 to a documentation platform 50. The documentation platform 50 is stored in a cloud 51.

[0088] The filling of the fresh concrete 20 in step c) is usually carried out using a filling system and a conveyor which is stationary positioned on a construction site, or the fresh concrete 20 is delivered using a truck and conveyed by the truck into the formwork opening 22 of the formwork 21 - not shown.

[0089] The optical measurements in step d) comprise the continuous measurement of a current distance from the at least one current fill layer height HS of the fresh concrete 20 in the formwork 21 to the optical sensor devices 30 during filling. With the aid of the optical sensor devices 30, a time measurement t of the change in the current fill layer height HS is simultaneously determined while measuring the distance in order to monitor the provided measurement intervals. Thus, a time stamp is set in the at least one computing device 41 in order to determine the current rise rate v B with high precision and in real time.

[0090] In this embodiment of the method according to the invention, the calculation of the current rate of rise v B is carried out in step e) using the measured values ​​from the optical measurement and the time measurement t, whereby the mean value of the last 5 to 20 optical measured values ​​is used. Various predefined bandwidths are used in the calculation to eliminate outliers in the measured values. The current rate of rise v B is calculated on an interval-related and average basis and is graphically displayed in the app 42 as a dashboard view 47, 48 - see Figure 2e). The temporal fill layer height development 49 is also calculated and graphically displayed in the app 42 - see Figures 2d) and 3b). The filling time of the fresh concrete 20 is shown on the abscissa and the current fill layer height HS is shown on the ordinate. The fill layer height development 49 shows the fill layers during the filling process as individual constant plateaus.The fill layer height development 49 is assigned to at least one component of the structure. This allows a historical schedule of the filling process for the structural component to be created, thus providing sufficiently detailed documentation.

[0091] In additional embodiments of the method according to the Figures 1 to 3 is in Figure 4a further sensor control system 125 is shown, in which the additional method can be implemented. The sensor control system 125 essentially has the same functional and structural features as the sensor control system 25, wherein a further terminal device 45 is located in the sensor control system 125. Before step a), several parameters of the formwork 21 and the ambient conditions are provided in the app 42, which can be taken into account in the calculation of the current climbing speed v B . These include at least a height of the formwork 21 as well as at least one material parameter of the fresh concrete 20 and individual further parameters, such as the bulk density of the fresh concrete 20, a fresh concrete temperature, a setting time, a type of compaction of the fresh concrete 20, and an end of setting at a reference temperature.In addition, the app also provides the air temperature, a reference temperature, an installation temperature, a formwork type 21, or a surface condition of the formwork skin 24. The app 42 transmits the measured values ​​via a mobile network 44 to a documentation platform 50 in order to prepare them there according to documentation requirements - see . Figure 4 . The documentation data as well as the measurement data and calculated data can be provided to the additional terminal 45 to another user by connecting the additional terminal 45 to the documentation platform 50.

[0092] In a supplementary embodiment of the above-mentioned methods according to the Figures 1 to 3 or Figure 4the compaction phase of the fresh concrete 20 and the degree of compaction of the fresh concrete 20 are determined. In addition, the temperature at the formwork 21, the ambient humidity and the ambient temperature are measured before calculating the current climbing speed v B.

[0093] In a supplementary embodiment of the above-mentioned methods according to the Figures 1 to 3 or Figure 4 An interruption in filling is identified using at least some of the measured values ​​from the optical measurement. The measured values ​​from the optical measurement indicate an unchanged current filling layer height v B across several measuring points, so that an interruption in filling can be concluded.

[0094] In a supplementary embodiment of the above-mentioned methods according to the Figures 1 to 3 or Figure 4the measuring behavior of the optical sensor device 30 is adjusted taking into account the charge state of the energy supply for the optical sensor device 30.

[0095] In a supplementary embodiment of the above-mentioned methods according to the Figures 1 to 3 or Figure 4A filling system for filling the formwork 21 with the fresh concrete 20 is controlled when the at least one current rising speed v B of the fresh concrete 20 reaches the at least one provided limit value GW of the rising speed. The filling system comprises at least one conveyor for conveying the fresh concrete 20. The at least one computing device 41 or the app 42 can be connected to a control device of the filling system, so that if the limit value GW of the rising speed is imminently exceeded, simple intervention is carried out and the filling quantity of the fresh concrete 20 can be reduced. The app 42 comprises a safety level query, so that the conveying capacity of the conveyor can be throttled based on the safety level query.The safety level of the safety level query includes the current rate of climb v B , whereby the conveying capacity of the conveying means is reduced to at least 90% of the current conveying capacity.

[0096] In a supplementary embodiment of the aforementioned methods, these are designed as computer-implemented methods which are executed on the at least one computing device 41 or in the app 42. In this case, command data is created in the computing devices 41 or in the app 42 and sent to the control device 35, wherein the control device 35 causes a display device of an output device, such as the display 46, to output at least the warning signal WS on the display device when the at least one current climbing speed v B of the fill concrete 20 reaches the at least one provided limit value GW of the climbing speed of the fill concrete 20.

[0097] Figure 5shows a diagram with the current rate of rise v B of a fill layer, where the abscissa AGW represents the fill layer height HS and the ordinate OGW represents the duration of the filling process when filling the formwork 21 with the fresh concrete 20. The two arrows in the diagram show the current rate of rise v B , which is at the specified limit value GW. The specified limit value GW for the rate of rise is shown as a dashed line. Other possible limit values ​​GW1, GW2 for other rate of rise v B1 , v B2 are shown in the lines above or below and can be stored in the app 42 or in the computing device 41 for selection by the user. Another rate of rise v B can be shown with additional arrows in the same diagram.

[0098] Figure 6 and Figure 7show an embodiment of the optical sensor device 30 for monitoring the rising speed of fresh concrete 20, comprising at least one laser distance sensor 33 and a fastening device 31 for fastening at least the laser distance sensor 33 to a formwork 21, such that at least the laser distance sensor 33 can be positioned above the formwork opening 22. The optical sensor device 30 is wirelessly connected to the computing device 41, wherein the computing device 41 is designed to calculate a current rising speed v B of the fresh concrete 20 when filling the formwork 21 with the fresh concrete 20 at least with the aid of the measured values ​​of the optical measurements of the at least one current fill layer height HS and at least one time measurement t in at least one measuring interval, as previously described in the methods. The laser distance sensor 33 measures the fill layer height HS without contact.The laser 34 transmits a laser beam through the formwork opening 22 into the formwork 21 to the bottom of the formwork 21 when there is no fresh concrete 20 in the formwork 21. When the formwork 21 is filled with the fresh concrete 20, the laser beam only reaches approximately to the surface of the fresh concrete 20, with the range of the laser beam further shortening with increasing fill layer height in the formwork 20. Thus, the laser 34 measures the distance from the at least one current fill layer height HS of the fresh concrete 20 in the formwork 21 to the laser distance sensor 33 during the filling of the fresh concrete 20.

[0099] The control device 35 is designed as a microcontroller 36, which is connected to the computing device 41 or the app 42 to ensure the exchange of sensor data and command data at least with the laser distance sensor 33. The microcontroller 36 comprises a processor, a memory, and input / output (I / O) peripherals on a single chip.

[0100] The microcontroller 35 causes the output device on the mobile phone 41 to acoustically and visually display the warning signal WS when the at least one current climbing speed v B of the fresh concrete 20 reaches the at least one provided limit value GW of the climbing speed of the fresh concrete 20. A loudspeaker is provided on the mobile phone 40 as the output device for the acoustic warning signal WS, and a light signal is provided as the display device for the visual warning signal WS.

[0101] In addition, a storage device 37 is present in the optical sensor device 30, which is connected to the computing device 41 and / or to the app 42 by means of data lines or wirelessly for the exchange of data.

[0102] In addition to the laser distance sensor 33, a camera 32 is arranged on the fastening device 31. The camera 32 visually detects the current filling layer height v B , thus creating images of the current filling layer height v B . Such images can be transmitted wirelessly from the camera 32, for example via Bluetooth LE ®< , to the app 42 and thus to a display device, such as the display 46.

[0103] Additionally, a vibration sensor 38 is provided. The vibration sensor 38 is arranged in the optical sensor device 30 and detects, on the one hand, a compaction phase during the filling process and, on the other hand, also detects external forces acting on the optical sensor device 30. For this purpose, the vibration sensor 38 is connected to the control device 35 for the exchange of vibration data.

[0104] Furthermore, an acceleration sensor 39 is arranged in the optical sensor device 30 as a vibration sensor, which simply detects vibration of the optical sensor device 30 and / or vibration of the formwork 21. The at least one vibration sensor is connected to the app 42 for data exchange. Furthermore, at least one position parameter of the optical sensor device 30 is determined using the vibration sensor. This allows the inclination or orientation of at least the laser distance sensor 33 to be determined. Furthermore, a microphone 39a is arranged in the optical sensor device 30 to receive acoustic sound waves.

[0105] In a supplementary embodiment of the aforementioned optical sensor device according to the Figure 6An AI module is present, which is connected to the computing device 41 and the app 42, so that the measured values ​​from at least the vibration sensor and the microphone 39a can be evaluated using artificial intelligence (AI).

[0106] In a further additional embodiment of the aforementioned optical sensor device according to the Figure 6 A temperature sensor is provided for measuring the temperature at the formwork 21. The temperature sensor is an infrared temperature sensor and measures the temperature of the fresh concrete surface, the formwork skin 23, and the reinforcement surface. In addition, an ambient temperature sensor and a humidity sensor are provided for measuring the relative humidity.
