Definitions

  • the present invention relates to a method for dynamically controlling a paving speed of at least one road finisher for a paving process according to claim 1. Furthermore, the invention relates to a road construction system for a dynamic paving process according to claim 14.
  • EP 2 514 871 A1 discloses a road construction system comprising a material supply chain, a road paver supplied with paving material from the material supply chain for pre-compacting a newly produced paving layer, and a compactor vehicle following the road paver for final compaction of the newly produced paving layer.
  • the road construction system also has an electronic material density module which is designed to detect the pre-compaction achieved by the road paver and to communicate it to the compaction vehicle, which adapts its final compaction performance based on the received data depicting the pre-compaction in order to produce a desired final compaction of the newly produced paving layer.
  • DE 10 2019 116 853 A1 discloses a system and a method for controlling the speed of a road paver. For this purpose, a feed rate of the paving material that is delivered from an asphalt mixing plant to a construction site is determined, wherein the paving speed of at least one road paver used on the construction site is adjusted depending on the determined feed rate. Alternatively, the speed of the road paver, in particular its maximum paving speed, can be varied on the basis of a detected maximum compaction rate of the compaction machines following the road paver.
  • EP 2 325 392 A2 discloses a road finisher with a compaction unit whose stroke can be automatically adjusted to the paving speed, so that even if the speed of the road finisher changes, a largely constant pre-compaction results.
  • the automatic adjustment of the stroke is carried out by means of a speed-dependent characteristic curve control. Comparable characteristic curve controls are available in EP 3 138 961 A1 , EP 2 366 831 A1 and EP 2 366 832 A1 revealed.
  • the invention is based on the object of providing an installation process with improved installation quality and improved installation performance.
  • the invention relates to a method for dynamically controlling a paving speed of at least one road paver for a paving process, wherein a paving speed for the road paver adapted to the determined material delivery performance is determined using a control system functionally connected to the road paver as a function of a variable material delivery performance of a material supply chain supplying the road paver with paving material.
  • a pre-compaction performance of at least one pre-compaction element of a paving screed of the road paver is adjusted depending on the paving speed adjusted to the material delivery performance in order to keep a constant pre-compaction achieved by means of the pre-compaction element.
  • the pre-compaction performance performed directly on the road paver is thus varied depending on the speed for the road paver determined dynamically on the basis of the determined material delivery performance in order to obtain a constant pre-compaction in the paving layer laid by the road paver.
  • the pre-compaction can therefore remain constant even if the paving speed of the road paver changes due to a varying material delivery performance.
  • this allows the speed of the road paver to be optimized taking into account the feed rate or the material delivery capacity in order to achieve an improved paving performance.
  • this optimization can be combined with a constant pre-compaction using the paving screed, i.e. the road paver is able to produce a paving layer with constant pre-compaction despite the paving speed being adjusted in terms of the material delivery capacity. This creates an improved paving quality.
  • the invention also promotes a continuous material supply through the material supply chain, since the operation of the road paver is adapted to the determined material delivery performance, i.e. no over- or undersupply of paving material on the construction site.
  • the invention allows a continuous paving process, since the paving layer can be produced using the road finisher without interruptions, taking into account the material delivery capacity. Fluctuations in the material supply can be easily compensated for using the invention, without changing the pre-compaction quality.
  • the installation process can be slower as the material delivery rate decreases and faster as the material delivery rate increases, without this dynamic leading to a change in the pre-compaction. This results in a continuous, i.e. uninterrupted, installation process on the construction site that leads to constant pre-compaction, beyond the material supply chain.
  • the invention derives the pre-compaction performance of the paving screed of the road finisher from the material delivery performance of the material supply chain, in that the material delivery performance determines the paving speed of the road finisher, on which the pre-compaction performance depends. This leads to a homogeneous, consistent pre-compaction result with uninterrupted paving.
  • the inventive idea of relating the material delivery performance to the pre-compaction performance via the adjusted paving speed enables an overall more powerful and higher quality paving process.
  • a user enters a maximum paving speed for the paving process of the road paver in the control system as a limit condition. This allows limits to be set on the speed control of the road paver on the construction site using expert knowledge.
  • the user can make the input in the control system dependent on the type of paving screed of the road finisher on the construction site, especially on its maximum pre-compaction performance. This means that the paving speed of the road finisher can only be accelerated to the extent that constant pre-compaction is still possible.
  • control system is functionally connected to the paving screed and, when the paving screed of the road paver is changed, which may change a possible maximum pre-compaction performance, prompts the user to confirm or update the maximum paving speed stored by the user as a limit condition in the control system.
  • the control system determines the maximum possible paving performance by the road finisher, taking into account the determined material delivery performance, and thus calculates a separate, maximum paving speed for the road finisher depending on the layer thickness and layer width to be produced using the paving screed.
  • the control system is thus able to calculate a separate, maximum paving speed for the road finisher for any construction specification, which is adapted to the material delivery performance.
  • This separately determined, maximum paving speed can in principle be less than, equal to or greater than the maximum paving speed stored by the user in the control system.
  • the maximum paving speed calculated using the control system is stored as the paving speed target value in a vehicle control of the road finisher that is functionally connected to the control system if this is less than or equal to the maximum paving speed entered by the user.
  • the maximum paving speed entered by the user it would be possible for the maximum paving speed entered by the user to be stored as the paving speed target value in the vehicle control of the road finisher that is functionally connected to the control system if the maximum paving speed calculated using the control system is greater than the maximum paving speed entered by the user.
  • the first alternative described above results in a paving process that is accelerated as much as possible depending on the determined material delivery rate, without risking an interruption in paving.
  • the second alternative mentioned above sets limits on the speed of the paving process through specialist knowledge, for example with regard to the maximum pre-compaction performance that can be achieved by the paving screed, in order to determine the maximum paving speed even with a very high material delivery rate in such a way that the pre-compaction performance can be adjusted to maintain a constant pre-compaction, even if the determined material delivery rate would actually allow a higher maximum paving speed. In both alternatives, the pre-compaction therefore remains constant.
  • the control system calculates a correspondingly adjusted, new maximum paving speed for the road finisher by detecting a changing material delivery rate and determines a time at which the new maximum paving speed is stored in the vehicle control system of the road finisher. This ensures that the speed adjustment of the paving process is only carried out on the road finisher when a corresponding recorded, increased or reduced material delivery performance of the material supply chain is noticeable on the construction site. This means that the road paver only reacts to an increased or reduced material delivery performance when it actually arrives at the construction site, i.e. when it affects the amount of material stored there.
  • control system can vary the time at which the new maximum paving speed is stored in the vehicle control of the road paver depending on the magnitude of the required paving speed change in such a way that, in principle, with a small change in paving speed with regard to a changing material delivery rate, the new maximum paving speed in the vehicle control of the road paver tends to be stored or controlled later than with a large change in paving speed with regard to a changing material delivery rate.
  • This principle can mean that only short-term, minor changes in the material delivery rate can be ignored, i.e. cannot be unnecessarily transferred to the operation of the road paver. This promotes energy-efficient operation of the road paver.
  • the new maximum paving speed calculated using the control system is stored as the new paving speed target value in the vehicle control of the road paver that is functionally connected to the control system if this is less than or equal to the maximum paving speed entered by the user.
  • the maximum paving speed entered by the user it would be possible for the maximum paving speed entered by the user to be stored as the paving speed target value in the vehicle control of the road paver that is functionally connected to the control system, or for this to remain set if the new maximum paving speed calculated using the control system is (still) greater than the maximum paving speed entered by the user. In both alternatives, it can be ensured that a maximum paving performance combined with consistent pre-compaction is possible on the basis of the determined material delivery performance.
  • the first alternative takes into account that the maximum paving speed is set in relation to the material delivery capacity in such a way that the road finisher only accelerates the paving process to the extent that it can carry out the paving process continuously when the material supply is low, i.e. disadvantages associated with a material supply bottleneck and a resulting stopping of the road finisher, such as the screed sinking during the stop and/or impairments of the layer thickness surface quality, for example due to imprints, can be avoided.
  • the control system therefore only causes the road paver to accelerate the paving process in such a way that the road paver does not stop on the construction site and paving is always carried out with a constant pre-compaction.
  • the control system adjusts the paving speed setpoint, in particular the new paving speed setpoint, depending on a preselected minimum material supply and/or depending on a preselected maximum material supply of paving material present in the immediate vicinity of the road paver, i.e. on the construction site, in such a way that the minimum material supply is not under- and/or the maximum material supply is not exceeded during the paving process.
  • This provides additional security that there is always a sufficient material buffer for the road paver on the construction site, i.e. there is never too little or too much paving material. This promotes a continuous paving process by preventing the road paver from having to stop during the paving process due to insufficient or insufficient material supply.
  • an initial paving speed of the road finisher were defined before the start of the paving process and a target layer thickness and target pre-compaction were stored as process parameters in the control system for the initial paving speed, for example by user input.
  • the initial paving speed can be selected, for example, so that the road finisher can start slowly at the start of the paving process, i.e. the road finisher temporarily carries out the paving process at a "warm-up speed" at least at the start of the paving process, i.e. is not immediately controlled at maximum paving speed.
  • These basic settings selected on the road finisher before the start of the paving process can be transferred from the road finisher to the Control system, preferably when they are detected at the start of the paving process on the road finisher and/or in the paving result, whereby this initiates the operation according to the invention on the control system to keep the pre-compaction constant at maximum paving speed. It would be conceivable that the activation of the operation according to the invention to keep the pre-compaction constant at maximum paving speed only takes place after a predetermined warm-up time has elapsed, for example 5 minutes after the start of the paving process, so that the drives and units installed on the road finisher reach a desired operating temperature before the road finisher adapts its speed to the changing material delivery capacity of the material supply chain supplying it.
  • the initial paving speed of the road paver could be brought to a maximum paving speed adjusted to the material delivery rate or to the maximum paving speed set by the user by means of its vehicle control using a ramp function, so that the working units of the road paver, which are still cold at the beginning of the paving process in particular, including in particular the speed-dependent pre-compaction device, can slowly start up.
  • the initial paving speed is stored in the vehicle control system as a paving speed target value at the start of the paving process, whereby a speed change recorded on the road paver or determined by means of the control system, in particular a speed change from the initial paving speed to the maximum paving speed entered by the operator or to the maximum paving speed calculated on the basis of the material delivery performance, causes the control system to calculate a correction factor for adjusting the pre-compaction performance for the natural change in pre-compaction that is predictable due to the speed change and to store this in a screed control system of the road paver, which uses the correction factor to adjust the operation of the compaction element in such a way, in particular at a specific time, that a pre-compaction achieved with the speed change essentially corresponds to the target pre-compaction defined for the initial paving speed.
  • the speed change initiated by the control system therefore determines the extent of the resulting correction factor, by which the pre-compaction performance is adjusted to compensate for the natural change in pre-compaction. This means that, despite a material supply-dependent target paving speed of the road paver changing compared to the initial paving speed, an adjustment of the pre-compaction performance can be controlled using the correction factor to compensate for the changed target paving speed, so that constant pre-compaction is guaranteed.
  • the correction factor is used by means of the screed control to vary a stroke of the compaction element, to vary an executable contact force by the compaction element and/or to vary a speed of the compaction element.
  • the variation of these process parameters can be combined as desired in order to enable a pre-compaction performance adapted to the change in speed using the screed.
  • a layer thickness deviation from the target layer thickness is calculated by real-time measurement of the layer thickness produced, on the basis of which a layer thickness correction factor is determined and used by the screed control system to control the height of the paving screed.
  • a layer thickness correction factor is determined and used by the screed control system to control the height of the paving screed.
  • a pre-compaction deviation from the target pre-compaction is determined by real-time measurement, whereby a system used for post-compaction, for example a roller following the road paver, compensates for the pre-compaction deviation by means of dynamic post-compaction modulation so that the overall residual compaction deviation is minimal.
  • the invention means that the pre-compaction result can be produced essentially consistently along the paving section, i.e. is constant, deviations from the target pre-compaction that are determined in exceptional cases can be easily compensated by means of the subsequent post-compaction system.
  • the post-compaction system benefits from a constant pre-compaction created essentially along the entire paving section by the road paver, so that it can compensate for any isolated, detected deviations from the target pre-compaction without great effort.
  • At least part of the control system can, as a cloud-based application, record predetermined construction planning values, e.g. from a control center connected to it, and/or dynamic paver and screed process data of the road paver determined during the paving process and, based on this, at least one target process value for the paving process, in particular the paving speed adapted to the varying material delivery performance and/or at least one correction factor, in particular Calculate the correction factor for adjusting the pre-compaction performance and transmit it to another part of the control system, which stores the calculated target and correction values for the vehicle control and/or the screed control.
  • the part of the control system configured as a cloud-based application can record dynamic material delivery process data determined during the material delivery process carried out on the basis of the material delivery chain and, based on this, calculate the material delivery performance of the material delivery chain, in particular in real time, as well as the paving speed to be adjusted thereto and transmit this to the other part of the control system, which maintains the adjusted paving speed of the vehicle control of the road paver.
  • IT resources can be outsourced as a web application. This makes it possible to connect several installation processes carried out on different construction sites with the part configured as a cloud-based application.
  • the cloud-based part of the control system could thus be used universally for many construction site projects at the same time.
  • control system is not only partially but entirely available as a cloud-based application and calculates all target process values and correction values for the paving process at least as a function of the variable material delivery rate and makes these available directly to the vehicle control and/or the screed control of the road paver in order to achieve constant pre-compaction.
  • the invention further relates to a road construction system for a paving process.
  • the road construction system comprises a control system, at least one road paver functionally connected to the control system, at least one logistics system functionally connected to the control system and at least one material supply chain that supplies the road paver with paving material, the variable material delivery performance of which can be recorded using the logistics system and made available to the control system.
  • the control system is designed to determine a paving speed for the road paver that is adapted to the determined material delivery performance.
  • a pre-compaction performance of at least one pre-compaction element of a paving screed of the road paver can be adapted depending on the paving speed that is adapted to the determined material delivery performance.
  • the control system is designed to determine a maximum paving performance that the road paver can achieve, taking into account the material delivery performance displayed to it by the logistics system, in order to calculate a maximum paving speed for the road paver depending on the layer thickness and layer width to be produced using the paving screed, and to store the maximum paving speed calculated using the control system as the paving speed target value in a vehicle control of the road paver that is functionally connected to the control system if this is less than or equal to a maximum paving speed entered by a user on the control system as a limit condition.
  • control system is designed to store the maximum paving speed entered by the user as a limit condition in the vehicle control of the road paver that is functionally connected to the control system if the maximum paving speed calculated using the control system is greater than the maximum paving speed entered by the user.
  • control system it would be useful for the control system to be set up to determine a changing material delivery rate and to calculate a correspondingly adjusted (new) maximum paving speed for the road paver and to determine a time at which the (new) maximum paving speed is to be stored in the vehicle control system of the road paver.
  • This variant therefore makes it possible to ignore only short-term, negligible changes in the material supply, so that the road paver travels at as constant a paving speed as possible.
  • control system can be configured to determine the time at which the new maximum paving speed is stored in the vehicle control system of the road paver. to vary depending on the magnitude of the required paving speed change.

  • the road paver only accelerates the paving process in such a way that there is no under- or oversupply of material on the construction site. An undersupply of material would in fact lead to the risk that the road paver would have to interrupt the paving process.
