Description

Embodiments of the present invention provide an apparatus and method for compaction control. Further embodiments provide a road or Bodenverdichtungsmaschine with appropriate control.

In general, the present invention relates to the field of rollers, for example, road rollers for compacting a road or road surface. A preferred embodiment of the invention relates to a method for controlling the compression of a material layer to be compacted by a roller, such as earth or asphalt layer.

As a result of the compaction work of a roller, a homogeneous and sufficiently compacted field is generally desirable because this is the prerequisite for highly loadable floors and durable road surfaces.

In road construction, it is important that the road surface applied by road pavers, such as asphalt material, is subsequently compacted by road rollers. For this purpose, move one or more road rollers during the labor input in a specified by one or more road pavers area in which asphalt material was applied. To densify the asphalt material sufficiently, each area of the road is run over several times by a road roller. For this purpose, the road roller drives off the road surface in several tracks, as this is usually wider than the roller drum. After the road roller has run over the road surface in individual lanes for a first time, this then begins with another crossing at the first track already crossed over.

In the known systems, compaction values of the area to be compacted during rolling (compacting) are measured and displayed to the driver on a monitor or display. For example, are from the DE 20 2009 008 592 U1 and the DE 694 34 631 T2 Devices for measuring the degree of compaction of a ground surface known with a monitor or display, which in the cab of the compacting machine is placed and used to display measured and / or calculated values such as compaction values. Based on these values, the driver can then recognize which areas have already been sufficiently compacted and which areas must be further compressed.

Furthermore, the describes EP 1 985 761 A2 a method for determining a degree of compaction of a surface area of a traffic area to be compacted, a system for carrying out this method and a compacting machine with this system. During a passage over the area to be compacted, position data of the compacting machine are determined and parameters are measured which are suitable for determining the compaction effect. These parameters are assigned to previously defined subareas and a current degree of compaction for the subareas is calculated from these parameters. In the case of repeated passage of the partial surfaces, the previously measured parameters are included in the calculation.

In this case, a determination of the degree of compaction is usually carried out at each crossing of the roller on the surface to be compacted by the introduced into the ground or acting in the underground forces are measured by means of a compaction meter. From the measured values, a degree of compaction of the subsurface can then be calculated. Thus, by repeatedly driving over the area to be compacted, a change in the compaction of the subsurface can be determined. Such a measuring system is for example in the EP 3 147 406 A1 described.

However, a repeated crossing of the roller over a substrate can also quickly lead to over-compression or even damage to the ground, for example, if this has different substructures or run in supply or disposal lines. Thus, a substructure, for example, various materials such as earth, sand, stone or rock, or even laid wastewater or sewer pipes, manholes or the like, and thus have a compression in this area influence. D. h., An optimal compaction of the substructure is, for example, reached earlier in such places than at other locations in the substructure no pipes or the like run. Are in the substructure already introduced supply or disposal lines and / or pipes, manholes or the like, so over-compression in these areas can damage them, which can sometimes lead to high repair costs.

Since it is incumbent on the driver in the known systems essentially to adjust the corresponding parameters (compaction performance) of the machine during the compaction process, optimum compaction can not always be achieved, in particular for the described substrates with different substructures, since the driver has different materials in the substructure or pipes or the like extending therethrough may not be apparent. Therefore, there is a need for an improved approach.

The object of the present invention is to provide a concept for compaction control with increased accuracy.

The object is solved by the subject matter of the independent patent claims.

Embodiments of the present invention provide a compacting control apparatus for compacting a portion of a subsurface by means of a road or soil compaction machine. The device comprises an interface, a calculation unit and a controller. Actual compression values, namely a first actual compression value for a first portion of the range and a second actual compression value for a second portion of the range, are determined via the interface. The calculation unit is configured to compare the first actual compression value with a first target compression value for the first portion to determine a first plan compression value (i.e., a compression value for, for example, a next iteration) for that first range. Further, the calculation unit compares a second actual compression value with a second target compression value for the second portion to determine a second plan compression value for that range (again, for example, for the next iteration). The control of the compaction control now determines a first machine control parameter based on a first plan compaction value for the road or compaction machine, wherein the compaction of the first section takes place or should take place as a function of the first machine control parameter. Analogously, starting from the second plan compression value, a second machine control parameter for the road or soil compaction machine is determined, starting from which the compaction of the second section takes place or is to take place.

According to embodiments, the compression takes place in several iterations, so that the first and the second section are run over several times. In the first Crossing (first iteration), the first and second actual compression value for a first and second area is determined. According to exemplary embodiments, this first and second actual compression value can then be temporarily stored, so that then, during and before the second iteration, the first and second actual compression values from the first iteration are compared with the first and second desired compression values for the first and second sections and then obtain the first and second plan compression values for the second iteration. Similarly, for a third iteration, starting from the actual compression values of the second iteration, the corresponding plan compression values for the third iteration, e.g. By adjusting the plan compression values from the second iteration.

Embodiments of the present invention are therefore based on the finding that a size which can be used to control or regulate the compression in the relevant section can be determined by adjusting the actual compression values in relation to the target compression values in sections. According to embodiments, for example, the compaction power of the machine (for example, vibration frequency and / or amplitude) or even a crossing speed can be regulated. The advantage of this approach is that even before another crossing over an already pre-compressed area, the compression capacity can be reduced and thus any over-compaction of the subsurface is avoided. In other words, this means that in comparison to the prior art, the compression capacity can be regulated back before another crossing in order to avoid a possible error (over-compression). Furthermore, the above-described concept also reduces the wear of the machine (eg the road / ground compressor or the roller) as well as the fuel consumption, since the compaction power introduced into the material is adjusted taking into account the precompression on the basis of the already specified compaction values of the ground ,

The disadvantages listed above are thus overcome, since it is no longer up to the driver to adjust or change the compaction performance of the machine accordingly. Accordingly, a more uniform compaction is achieved over the area to be compacted, since the compaction performance of the machine is adapted to the condition of the subsoil from the second pass. In addition, any damage to eg. Already laid in the ground pipes, channels or the like are thereby avoided.

According to embodiments, a position value is assigned to each actual compression value, target compression value and plan compression value. In this case, according to further exemplary embodiments, the device may comprise a position sensor which is designed to associate a position value with the actual compression value and / or the plan compression value. According to exemplary embodiments, the sections of the area may comprise a continuous or a varying lateral extent, so that, depending on requirements, a finely divellable subdivision of the area to be compacted is also possible.

To determine the actual compression values, there are in principle two different approaches. According to a first approach, the device may include a compression degree sensor which, in a previous iteration, determines the actual compression to allow the plan compression value for the current iteration to be calculated by the comparison discussed above. According to a second variant, according to embodiments, the device may comprise a radio interface which receives, for example, from another road or ground compressor an actual compression value via a sensor arranged there. This variant is particularly advantageous if the compression is to take place with a plurality of road / ground compressors driving one behind the other, so that the downstream road compressor (corresponding to the second iteration or the second compression) its compression power starting from the current / measured actual compression for the still overrunning area, wherein the actual compression value is determined by the preceding compacting machine.

According to further embodiments, when calculating the plan-compression values, an actual temperature value, which is determined, for example, together with the actual compression value, can also be taken into account. In this case, for example, a so-called simulation of the cooling behavior with the input parameters of the actual temperature values for the respective area can be used.

Another embodiment relates to a road or Bodenverdichtungsmaschine such. B. a roller with a corresponding device. According to one embodiment, this road compaction machine is configured to provide the compaction power (eg, the amplitude or frequency of a vibrating bandage) in response to the first and second machine control parameters to adapt or to choose. In this case, according to an exemplary embodiment, the compression power can be varied in sections, ie, so that the first section is compressed with a different additive compression than the second section. This can also reduce the power to zero. According to a further embodiment, it is also possible to lock an area for another crossing. Alternatively or in addition to the variation of the compaction performance, the speed of movement of the road compaction machine can be adapted in accordance with embodiments according to the first and second machine control parameters.

A further embodiment relates to a method for compression control comprising the steps of receiving the actual compression values, comparing the actual compression values with the target compression values for the respective sections, and determining at least the first and second engine control parameters based on the plan compression values. The method can be carried out computer-implemented according to further embodiments, i. H. Thus, according to one exemplary embodiment, a computer program with a program code for carrying out the method is created.

Before explaining embodiments of the present invention with reference to the accompanying drawings, it should be noted that like and equivalent elements and structures are provided with the same reference numerals, so that the description of which is mutually applicable or interchangeable.

Fig. 1 Fig. a shows a device 1 for compaction control of a region 21 of a subsurface. The area 21 is in Fig. 1b and here comprises a first section A1 and a second section A2. The area 21 of the ground may be, for example, a road or a ground that is connected to a road or soil compaction machine, such. B. a roll to be compacted. For both areas A1 and A2, a desired target compression is known. The target compression for the first region A1 is stored as the first target compression value, while the target compression for the second region A2 is stored as the second target compression value. The two target compression values may be the same or different. Reasons for different Zielverdichtungen are, for example, that in the subsurface additional elements such as pipes are provided.

The device 1 comprises, for example, an interface 1S for receiving current compression values, such. B. measured compression values for the areas A1 and A2, a calculation unit 1 B and a controller 1C.

The interface 1S receives actual compression values for the sections A1 and A2, ie at least the first and second actual compression values. It should be noted here that the subdivision of the area 21 into any number of sections is possible so that further compression values can also be received via the interface 1S. The first and second actual compression values are made available to the downstream calculation unit 1B. The calculation unit 1 B receives externally, z. B. from a planning office with the aid of a radio interface, the corresponding target compression values, ie, the first target compression value for a first section A1 and the second target compression value for the second section A2. Other target compression values can of course also be obtained depending on the subdivision of the area 21. The authorization unit now compares the obtained actual compression values with the target compression values for the respective sections, in sections So-called plan compression values, ie to obtain a first plan compression value for the section A1 and a second plan compression value for the section A2.

Based on these plan compression values for the different sections A1 and A2, the control of the road or soil compaction machine is now carried out by means of a controller 1C, which may also be part of the road or soil compaction machine (not shown), for example. For this purpose, the control determines, based on the plan compression values, the respective machine control parameters, as a function of which the compression of sections A1 and A2 is to take place. The assignment of a first machine control parameter to the section A1 and a second machine control parameter to the section A2 continues.

These machine control parameters can, for example, influence the compaction performance, for example by adjusting the frequency and / or amplitude of the vibrations as a function of the machine control parameter.

According to an alternative, a machine control parameter may be used to regulate a speed of travel of the individual sections A1 and A2.

It should be noted at this point that the compaction of the lining 21 with the sections A1 and A2 generally takes place in a plurality of iterations. Furthermore, it is also frequently the case that the device 1 is arranged on a road / soil compaction machine, so that the sensor for determining the actual compaction values is also arranged on the same machine. This has the consequence that, when measuring the first actual compression value, the compression of the section A1 already takes place by means of a predetermined compression rate or speed. The same applies to the compression of section A2. The background to this is, in addition to the arrangement, also the measurement principle frequently used in the compaction measurement, according to which the frequency response of the background in section A1 or A2 is evaluated for the introduced vibration energy.

According to embodiments, the actual compression values for the sections A1 and A2 obtained in the first iteration are used to calculate the plan compression values for the respective sections A1 / A2, starting from which the compression power is adjusted in the second iteration.

It should also be noted at this point that, according to exemplary embodiments, the compression capacity can vary from section to section, so that, for example, the still required compression at section A1 is smaller than the compression still required than at section A2.

3. (c) Bestimmen von mindestens einem Verdichtungswert der Materialschicht während des Verdichtungsvorgangs;
4. (d) Abspeichern der Positionsdaten

dadurch gekennzeichnet, dass (e) vor jeder weiteren Überfahrt der Walze über den Abschnitt der bereits vorverdichteten Materialschicht die Verdichtungsleistung der Walze anhand der gespeicherten Werte aus Schritt (d) an den zu erreichenden Endverdichtungswert von der Vorrichtung zur Regelung der Verdichtungsleistung angepasst wird.According to further embodiments, a method for compaction control may be as follows: Method for compaction control of a to be compacted by a roll of material layer 21, such as earth or asphalt layer, wherein the roller is a device 1 for controlling the compaction performance, a measuring system for determining a compression value of Material layer and an optional position determining system (GNSS / GPS), and with a predetermined Endverdichtungswert the material layer to be compacted, comprising the following steps:

1. (a) determining position data at the beginning of a portion of the material layer to be compacted;
2. (b) passing the roller over the section at a first compaction power;
3. (c) determining at least one compaction value of the material layer during the compaction process;
4. (d) storing the position data

characterized in that (e) prior to each further passage of the roller over the portion of the already precompressed material layer, the compaction performance of the roller is adjusted from the device for controlling the compaction power to the final compaction value to be reached from the stored values from step (d).

In the above-described approach is also conceivable that the actual compression values by means of another machine, eg. B. another compaction machine are determined and then transmitted to the compaction machine with the device 1 by radio, so that the device 1 determines the first direct crossing the plan compression values from the obtained actual compression values. So that means. that the data obtained during the first crossing according to step (d) are transferable to other rollers (either directly by radio connection or indirectly by "storage" on a server), As in road construction usually several rollers are in use (so-called. Roll Association). On the basis of this data, other rollers can adjust the compaction power of the machine from a further passage (from the second crossing) over an already precompressed section accordingly.

According to a further embodiment, alternatively or in addition to the compaction performance, the driving speed can also be adjusted. In addition to the compaction performance, the speed of the roller also influences the compaction of the ground. When rolling asphalt surfaces, a constant travel speed of the roller is aimed at for an optimum and homogeneously compacted surface. However, it may be necessary that some of the above-mentioned sections in which, for example, the substructure has different materials or in which already sewage or sewer pipes, manholes or the like were laid, the roller should go faster or slower to damage the To avoid subsurface. Another example in this context are bridges, which usually have a concrete surface as a base. Here it is particularly important that the bridge structure after rolling of the asphalt has no damage due to the vibration of the roller drum.

Subsequently, reference will be made to Fig. 2a and 2 B another embodiment of the compression control explained. Here, it is assumed that the compression takes place with a roller 10.

In Fig. 2a a roller 10 with a vibrating bandage 12 and a non-vibrating bandage 13 is shown on a substrate 20. By the bandage 12 corresponding vibrations 25 are introduced into the substrate 20, that is, the substrate 20 is additionally compressed by the bandage 12. On the roof of the roller 10, a position determining system 30 (GNSS / GPS) is arranged. The positioning system 30 receives satellite signals 65 from a satellite system 60 which is in Fig. 1 is represented by three satellites 61 to 63. On the basis of the satellite signals 65, the exact position of the roller 10 can be determined continuously. Alternatively, other positioning systems may be used, such as a Local Positioning Radar (LPR) in which a base station transmits signals received from transponders located in known locations in space, a geodetic positioning system consisting of a total station (tachymeter) and one on the roller arranged prism (retroreflective triple prism or triple mirror), or other known positioning systems used in the field of construction machinery. Also, a combination of different positioning systems is conceivable, for example, a combination of a satellite-based and a geodetic positioning system in the area of bridges or underpasses, since there the satellite reception is poor or not available. The roller 10 further comprises a device for controlling the compaction performance and a measuring system for determining a compaction value of the material layer 20 (both not shown).

As in Fig. 2b illustrated, the roller 10 moves during the compression process in the direction of travel F over a surface 21 of the substrate 20. The compacting surface 21 and the substrate to be compacted 20 is divided into four different sections A to D, the nature of the substrate in each of the four sections A to D is different. Thus, for example, the section A directly below the roller 10 made of earth or gravel, whereas in the sections B and D, the lower portion of the substrate 20 consists of one or more stone layers 27. In section C, a pipe 28 is laid in the substrate 20, for example a sewer pipe. Here it is possible that the substrate 20 consists of earth and sand. In this respect, it can be assumed that the ground 20 in the four sections A to D is compressed to different degrees during the passage with a roller, ie, after the first crossing of the roller no uniform and homogeneous compression occurs.

Fig. 2b shows a plan view of the area to be compacted 21 Fig. 2a ie with a view from above. The roller 10 is located in a section A1 and moves in the direction of travel F in the subsequent section B1 on the first track 1. The individual sections and tracks are indicated by dashed lines 40 and 41. In order to sufficiently compact the surface 21, the roller 10 repeatedly passes over the surface 21 in a plurality of webs 1 to 3. The texture of the ground is different in each of the four sections A to D. However, this is not readily apparent to the roller driver. For example, he will not be able to see the wastewater pipe 28 running in the ground transversely to the direction of travel F of the roll 10 in section C.

The method provides that first, ie at the beginning or when entering a section A1... D3 of the material layer 20 to be compacted, position data of the roller 10 are determined. The roller 10 passes over each section A1... D3 in the first pass with a first compaction power and it is measured by means of the measuring system in each section A1 ... D3 determined at least one compression value of the material layer 20 during the compression process. The position data are stored together with the compaction values. Before each further passage of the roller 10 over the sections A1 ... D3 of the already precompressed material layer 20, the compaction power of the roller 10 is adjusted from the device for controlling the compaction performance based on the stored position and compaction values to a predetermined and to be reached Endverdichtungswert. In this case, for example, the vibration frequency and / or the amplitude of the vibration of the vibrating drum bandage 12 can be reduced if the corresponding section has already been sufficiently compacted or if a further pass of the roller 10 with an unchanged compaction power would lead to overcompaction of the corresponding section.

As in Fig. 2a shown, it may be arranged on the roller 10, a temperature sensor 14. In particular, when rolling asphalt material so temperature data can be included with each crossing and, for example, a cooling behavior of the asphalt material can be calculated, which is included in the calculation of the compaction performance of the roller to be set.

Fig. 3 shows two rollers 10 and 11, which drive over a surface to be compacted 21 while compacting the substrate 20. Such a roll dressing is used for example in road construction, since the applied asphalt material cools down very quickly and the surface can not be compacted quickly enough with a roller. In this case, it is conceivable that the determined data, such as positions and compaction values, are exchanged between the rollers 10 and 11 via communication units (not shown) arranged on the rollers and antennas 31 and 33 via a communication connection 81. Also, all recorded and calculated data, such as positions and compression values, can be logged on the server 70 in order to subsequently evaluate the performed compaction work.

If other rollers are still in use at the construction site, it would also be conceivable to exchange data via a server 70 with which the individual rollers communicate via a network 50. For this purpose, communication links 82 and 83 are established between the rollers 10 and 11 and the network 50, the server 70 being connected to the network 50 via a connection 84.

Fig. 4 shows that the determined data such as positions and compression values can also be transmitted to a mobile device 90 via the communication unit (not shown) arranged on the roller 10 and the antennas 31 via a communication connection 85. Such a device 90 may be, for example, a laptop 91, a smartphone 92 or a tablet PC 93. However, it is also conceivable that a smartwatch or a data glasses or the like (in FIG. 4 not shown) can receive the signals emitted by the antenna 31 signals 85. Each of the mobile devices 90 has a corresponding interface 88 for receiving the data.

An installed and executable on said mobile devices 90 software (eg App) is able to display based on the received data, for example, the compaction values of the substrate or machine parameters of the roller graphically on a display of the mobile device or in the data glasses d. H. to visualize for the driver of the roller or also for the construction site personnel working on the construction site or in a construction site office. Also, all recorded and calculated data, such as positions and compression values, may be logged on the mobile terminal 90, i. H. be stored in order to be able to subsequently evaluate the compaction work carried out.

Furthermore, it is possible that a software installed and executable on the server 70 or on the mobile terminal 90 can perform a classification of the rollers on the basis of the data which were determined on the first passage of one or more rollers over the road surface. Thus, for example, in places or in sections where greater compression is necessary, heavy rollers are used with a greater compaction performance and in places or in sections where only slightly or no longer needs to be compressed, only smaller or lighter rollers are used. A division of sections may also be used to prohibit further driving over certain sections / areas, ie. H. Zones are defined in which the rollers are not allowed to retract. The software installed and executable on the server 70 or on the mobile terminal 90 performs calculations for this purpose and transmits the corresponding data to the individual rollers, so that there is, for example, a corresponding message or a message / alarm on an on-board computer for the driver of the roller.

Also, according to embodiments, it is possible to use the above-mentioned server 70 not only to exchange data of the actual compression data, but also to Logging purposes. In this case, preferably all recorded calculated data are logged in order to be able to subsequently prove and evaluate the compaction work that has been carried out.

According to further embodiments, the adjustment of the compaction performance takes place in such a way that, in addition to the machine control parameter, a selection of the machine type also takes place for a further iteration. The background to this is that different machines can perform different compaction work, for example due to different impressed performances or different weights. For example, assuming that in the first iteration a very heavy compaction machine is compacted and the actual compaction values are taken, a different machine may be used for the second iteration where appropriate machine control parameters are adjusted. A possible scenario would therefore be that a heavy compaction roller is used at points or paths where a large compaction is necessary, while in other places where only slightly compacted, a lighter compaction roller is used.

According to embodiments, it may also be that individual sections do not have to be compressed at all, so that these sections or even whole zones are blocked for further passage, so that individual sections are provided with a blocking instruction, so that the rollers no longer retract here allowed.

As already indicated above, the compression or the individual compaction performance often depends on a surface temperature or a material temperature of the material to be incorporated, such. B. from the street to be installed. Therefore, according to embodiments temperature sensors may be provided, the z. B. are connected via the above-explained interface 1 S with the device 1 to the temperature, for. B. on the roller to monitor the asphalt compaction.

Asphalt cools continuously after application by the paver. During the first crossing, the temperature data is recorded and a cooling behavior is calculated, which is included in the calculation of the compaction power of the roller to be set. Depending on the temperature drop, a compression capacity must be reduced more or less. Note: After the first crossing of a roller over a freshly applied asphalt layer, its surface becomes Smoothed, so that the cooling behavior of the asphalt changed by the changed heat transfer between asphalt and the environment.
