Definitions

  • the present invention relates to a system according to the preamble of claim 1, as well as to a method according to the preamble of claim 5.
  • the laying and paving of roads, paths or squares is an extremely complex process.
  • the work result i. H. the quality of the pavement produced, determined not only by the setting of the machines, but also, for example, by the properties of the built-in (eg asphalt) and by environmental conditions. All of these parameters determine together what quality, for example, what smoothness, the road pavement actually has.
  • the machine operator sets the adjustment parameters of the machines. In doing so, he orientates himself to the existing or changing boundary or installation conditions - and to his experience. The more skill and experience the machine operator has in dealing with the work machine concerned, the higher the quality of the road surface produced. Conversely, this quality can also be very low if the machine operator has little experience or is faced with previously unknown boundary conditions.
  • Known system and method for applying a road surface by means of a paver are measured variables such as the Einbauarbeitsfahr für and the actual speed of a tamper supplied to the control unit for a given target size of a certain number of tamper strokes per unit length via the control unit each adapted to the driving speed of the paver tamper speed can be set.
  • the control unit transmits an electrical or electronic adjustment parameter to the magnet of a hydraulic variable displacement pump, which regulates the amount conveyed by the variable displacement pump and thus the speed of the hydraulic motor of the tamper.
  • US 2009/0142133 A1 such as DE 10 2008 058 481 A
  • the known system and method for applying a paving is used to optimize the quality of the applied paving a temperature-position model of the road surface on the site, compared with acquired actual temperature data at certain points of the construction site, and are working machines such as paver and rollers so to speak temperature dependent navigated at the construction site.
  • external influences such as the weather and cooling rates of the built-in material are taken into account, and a control unit and a control unit is used, wherein the control unit works self-learning and with a closed loop is operated.
  • Local actual temperature data are compared with those of the temperature-position model, mainly to steer rolls and control so that too hot spots are not rolled first and all through the rolling as uniform as possible degree of compaction and optimum flatness of the road surface can be achieved.
  • the DE 40 40 029 C1 proposes to set the frequency of the drive of a compacting unit in a road construction machine in dependence on a predetermined Einbaufahr für technik für arithmetic processing unit (PE) and predetermined parameters of the layer to be installed.
  • a setpoint curve for the time course of Einbaufahr nie is specified.
  • the WO 00/70150 A1 proposes to measure the temperature of a pavement just made with a sensor and to control a paver or a subsequent compaction machine according to the measured temperature.
  • a multi-channel control system for a road construction machine is further from the DE 195 37 691 C5 known.
  • this control only relates to measuring the temperature of a screed and keeping it constant even if one heating element fails. There is no feedback with other setting or installation parameters.
  • the object of the invention is to improve a known system and method for applying a road surface to the effect that with greater certainty, a higher quality of the pavement produced is achieved.
  • the system according to the invention for applying a road surface has a control unit which is designed to determine, taking into account measured variables, the optimal setting parameter for achieving at least one predetermined target variable, to generate a command data set representing a plurality of optimum setting parameters, and to send this command data set to a control unit to transfer.
  • the control unit comprises a controller block and a simulation block connected thereto.
  • the controller block can make a suggestion for a new set of setting parameters, which is then fed to the simulation block.
  • the simulation block simulates which work result is achieved with the adjustment parameters proposed by the controller block. This simulated work result can then be compared with the specified, targeted work result. If necessary, the proposed adjustment parameters are adjusted again.
  • a neural network for simulating the values of the at least one target variable resulting from a group of setting parameters.
  • a neural network is particularly well-suited to the complex work environment of applying a pavement in which nearly all adjustment parameters are in a complex, interdependent relationship so that changing one adjustment parameter can cause a change in several other quantities.
  • other comparable algorithms can be used.
  • a simulation is carried out to determine optimal setting parameters with the set of setting parameters, which values of the at least one target variable result with these setting parameters. This simulation of the target values or of the process result enables a statement as to how well the specified target values can be achieved. From this it can be deduced which setting parameters could possibly be improved.
  • Setting parameters are defined as "optimal" if the values of the at least one target variable resulting from the simulation lie within a predefined tolerance of the at least one target variable. For example, it can be specified that the width of the pavement to be produced with the road paver may differ by + / two centimeters from the specified target size.
  • the setting parameters already determined to be "optimal” may be recorded, or a suggestion may be made for a new set of set parameters, including those already defined as “optimal.” Setting parameters are checked and changed if necessary.
  • the main advantage of the system is that it no longer has to adjust the individual setting parameters of the working components of a working machine based on its experience, for example the slope and temperature of a screed on a paver or the frequency of a tamper strip.
  • the user enters into the system, via a terminal, a data interface or a data carrier, target values for the road surface to be applied.
  • These target values are a description of the work result to be achieved, ie the road surface to be produced.
  • These target variables can therefore include, for example, construction site data such as the length, the width, the gradient or the course of the road surface to be produced, or information about the sequence of layers of the road surface, including the thickness of the individual layers.
  • the user can now specify the work result and then trust that the system determines the optimal setting parameters and readjust if necessary.
  • the input of the target variables can be faster than the setting of the individual adjustment parameters if the latter had to be performed by the user.
  • the labor required for adjusting the setting parameters to changing environmental conditions. Both of these factors reduce the work required to operate the system and thus save costs.
  • the system provides for separation of the control unit from the control unit.
  • the control unit has the task of implementing the specified commands or manipulated variables in such a way that the corresponding setting parameters are taken up by the working components of the system.
  • the control unit serves to find out the optimal control values or setting parameters. This separation has the advantage that an adjustment of the setting parameters by the control unit must be made only when the setting parameters have been optimized and possibly tested. As a result, the adjustment of the working components of the system is changed less frequently, resulting in a more even work result.
  • a plurality of setting parameters are summarized by the control unit and transmitted together in a vector or command data set to the control unit. This summary of the instruction data into a block or vector serves to reduce the energy required to transmit the instruction data.
  • a set of optimum setting parameters for reaching this at least one target variable are determined in the control unit from measured quantities and from at least one predetermined target size, and the group of setting parameters is in a common Command data sent from the control unit to the control unit.
  • the system itself may preferably have a mixing plant, a construction site center and / or a plurality of relatively movable work machines, such as trucks, milling, feeder, paver and / or rollers, which in turn may each have one or more working components.
  • sensors are provided for detecting the measured variables, and if these sensors provide the measured variables detected by them to the control unit.
  • the determination of the optimal setting parameter for achieving the at least one target variable is carried out repeatedly in the operation of the paver.
  • a constant or at least repeatedly carried out verification of the setting parameters and, if necessary, an adjustment of the settings to changing environmental conditions can be carried out in order to achieve an optimal work result.
  • Optimal is the work result when it comes as close as possible to the specifications given by the target sizes.
  • the re-determination of the optimum setting parameters for achieving the at least one target variable could be carried out in the operation of the device whenever a measured variable deviates from a target variable by a predetermined amount, and / or after a predetermined time interval has elapsed.
  • the latter has the advantage that the renewed execution of the optimization is independent of the determination of individual parameters and thus, for example, the failure of individual sensors.
  • control unit it is possible to iteratively set a group of changed setting parameters and to use these changed setting parameters to perform a simulation of the values of the at least one target variable resulting from the changed setting parameters.
  • This iterative simulation has the advantage that the adjustment parameters can be constantly adapted and optimized during operation of the device. It is conceivable to carry out the iterative process until the values of the at least one target variable resulting from the simulation lie within a predetermined tolerance of this at least one target variable. If all the target values in the simulation are within a specified tolerance can be reached, the whole set of setting parameters can be considered as "optimal" and recorded.
  • a group of setting parameters is recognized as "optimal"
  • that group may be communicated in a common vector or command record from the control unit to the control unit, whereupon the control unit will adjust the individual working components to the predetermined setting parameters. It is conceivable to always transmit the entire command data set of all possible adjustment parameters to the control unit. However, the effort for the transmission of the command data set can be reduced if only the changing setting parameters are transmitted to the control unit.
  • the command data record then signals the control unit which setting parameters are to be changed.
