Definitions

  • the invention relates to a method for operating a self-propelled road construction machine according to the preambles of claims 1 and 2. Furthermore, the invention relates to a road construction machine for producing a road surface according to the preambles of claims 9 and 10.
  • Road construction machines such as road pavers, feeders, but also road milling machines, are used to manufacture and remove road surfaces from preferably asphalt, but also concrete.
  • Such normally self-propelled road construction machines have various working components, which are permanently assigned to them or can be attached or removed.
  • a paver has a screed with a sliding plate, a tamper knife, a auger, a scraper conveyor with slatted frames and chains and the like.
  • a feeder on the other hand, has a scraper conveyor and a belt conveyor.
  • a road milling machine on the other hand, has a milling drum or a planer.
  • the road construction machines mentioned can have a storage container for receiving road construction material, a material conveyor and a chassis which is driven by a drive unit, such as a diesel engine.
  • a drive unit such as a diesel engine.
  • these road construction machines also have an operating station, from which an operator controls or controls the road construction machine together with its components, if necessary via a control unit.
  • the operator is tied to the control stand in order to control or monitor the construction machine and the individual components via the control unit.
  • vapors are released which make a longer stay in the control station uncomfortable or can be harmful to health in the long term. Because the operator is bound to the control station, he can only work within a limited action area. A flexible control of the installation process is not possible due to this connection to the control station.
  • the object of the present invention is to provide a method for operating a road construction machine and a road construction machine in which the health risks of the operator during operation are reduced without the installation quality of the road construction material being reduced.
  • the undercarriage and / or at least one further component or working component of the road construction machine are remotely controlled by an operator who is located outside of the control station via a transmitter module.
  • the data for controlling the undercarriage and / or the at least one further component are exchanged between the transmitter module and a receiving module, in particular a control unit, or between the transmitting module and in each case one receiving module of the undercarriage or the at least one further component.
  • the person can also be outside the control station, far from the road construction machine and is therefore at least not directly exposed to the health-damaging influences of the road construction machine.
  • the transmission module can be designed as a handheld device with an integrated processor and suitable transmission and reception means and input means.
  • an undercarriage and / or at least one further component of the road construction machine are remotely controlled by an operator who is located away from the road construction machine via a transmitter module, with data for control between the transmitter module and a receiver module or be exchanged between the transmitter module and a receiver module of the chassis or the at least one further component.
  • the data for controlling the undercarriage and / or the at least one further component are exchanged between the transmitter module and a receiving module, in particular a control unit, or between the transmitting module and in each case one receiving module of the undercarriage or the at least one further component.
  • the transmission module can be designed as a handheld device with an integrated processor and suitable transmission and reception means and input means.
  • a further advantageous exemplary embodiment of the present invention can consist in that a CAN bus system, in particular a control unit, of the road construction machine, preferably a CAN, is used directly by the transmitter module for exchanging data for controlling the chassis and / or at least one further component -Bus system of the chassis or the at least one other component is controlled.
  • This direct control of the CAN bus system enables the operator to directly access the function of the individual components or the chassis for the control. It is also conceivable that the connection between the transmitter module and the receiver module is reprogrammed as required, so that the transmitter module can also communicate with other CAN bus protocols of individual components or the road construction machine.
  • the transmission module is identified, in particular verified, by the reception module, in particular a control unit, or by the reception module of the chassis or the at least one further component, before the execution of a control command.
  • the reception module in particular a control unit
  • the reception module of the chassis or the at least one further component before the execution of a control command.
  • the transmission module is identified, in particular verified, by the reception module, in particular a control unit, or by the reception module of the chassis or the at least one further component, before the execution of a control command.
  • the transmission module is identified, in particular verified, by the reception module, in particular a control unit, or by the reception module of the chassis or the at least one further component, before the execution of a control command.
  • the transmitter module has not been successfully identified or verified, this can be announced by an acoustic or an optical signal.
  • Corresponding signal means for generating this signal can be assigned to the transmitter module, for example, so that the person equipped with this transmitter module is informed directly about the unsuccessful verification.
  • the invention can also provide that individual control commands from the transmission module to the reception module, in particular a control unit, or to the reception module of the undercarriage or the at least one further component are collected or that groups of several control commands are transmitted, whereby the group of Control commands several commands are executed automatically, preferably in a defined order.
  • groups of control commands can be compiled by a planning office, for example, before the road construction machine is started up. In this way, several individual commands can be put together to form a routine or group for the execution of a specific work step, such as leveling the screed. With this programming of command groups, a complete work step can be initiated or executed with a single command.
  • a preferred development of the device of the present invention can consist in that the data is exchanged wirelessly between the receiving module and the transmitting module.
  • the wireless exchange can take place in particular via radio, laser, WLAN or the like. This wireless transmission of commands makes the operator even more flexible, since the radius of his action is not restricted by the length of a cable.
  • the transmitter module is connected to the receiver module via a cable. Such a wired connection offers the advantage that the connection is particularly secure and the transmitter module can also be supplied with electrical energy in addition to the rapid exchange of data.
  • the transmitter module for direct data transmission with the receiver module and / or for charging an energy store of the transmitter module in a receiving device on the road construction machine, in particular the control station, is stored.
  • the transmitter module can also be used as a conventional control device from that of the road construction machine or the control station. If the situation requires or allows it, the road construction machine can also be controlled or checked conventionally directly from the road construction machine or the control station. If the control permits, the operator can then remove the transmitter module from the receiving device and move from the road construction machine or the control station into the immediate vicinity of the road construction machine, without giving up the possibility of checking or controlling the road construction machine.
  • the energy store, in particular the battery, of the transmitter module is charged.
  • the operator can be asked by the transmitter module to put the same back into the holding device on the control station.
  • the batteries are also charged with electrical energy.
  • the present invention can provide that the commands transmitted by the transmitter module are categorized into travel commands, work commands and special commands.
  • Various commands can be assigned to these individual command categories.
  • the "Driving commands” category includes commands related to the acceleration and steering of the construction machine and the choice of speed.
  • the category of "work commands” includes commands regarding the material feed rate, the pave width, the pave thickness, the pave speed and the like.
  • the category of "special commands” includes commands for transporting or driving the construction machine and the like.
  • a further advantageous exemplary embodiment of the present invention can consist in that feedback signals are sent from the reception module to the transmission module if a command is incompatible with a previous command or the state of the road construction machine, in particular the chassis and / or the at least one Another component that does not allow the command to be executed. If, for example, it is determined that the paver of the road paver is empty, no road building material - viewed in the direction of installation - can be transported in front of the screed. Rather, the transport of the road building material in front of the screed can only be initiated if there is enough road building material in the storage container. This generation of a feedback signal prevents malfunctions in the remote control of the road construction machine.
  • the construction machine is assigned a transmitter module and a receiver module, in particular a control unit, or the undercarriage or the at least one further component.
  • the undercarriage or the at least one other component can be remotely controlled by an operator who is located outside the control station via the transmitter module.
  • the transmitter module can be designed as a box-like hand-held device.
  • the functions that can be carried out by means of the transmitter module can also be transferred as software or app to a mobile radio device or a tablet computer, so that these devices can be used as a transmitter module for remote control of the road construction machine.
  • the construction machine is assigned a transmitter module and a receiver module, in particular a control unit, or the undercarriage or the at least one further component.
  • the undercarriage or the at least one further component can be remotely controlled by an operator located away from or next to the road construction machine via the transmitter module.
  • the transmitter module can be designed as a box-like hand-held device.
  • the functions that can be carried out by means of the transmitter module can also be transferred as software or app to a mobile radio device or a tablet computer, so that these devices can be used as a transmitter module for remote control of the road construction machine.
  • the transmission module or the corresponding electrical device can communicate with the reception module of the road construction machine by means of radio, laser, WLAN or the like.
  • This communication is preferably one encrypted communication, in particular to prevent unauthorized interference in the operation of the road construction machine.
  • communication between the transmitter module and the receiver module is only possible if a corresponding identifier or the exchange of verification codes has been carried out beforehand.
  • the transmitter module is intended to be used as a type of remote control for the remote control of the road construction machine, the same can also be docked into a corresponding receptacle on the road construction machine or the control stand of the road construction machine in order to operate the road construction machine in a conventional manner.
  • the transmitter module In the state docked on the road construction machine or on the control station, the transmitter module can be operated like a known control unit. A retraining of the operator is therefore not necessary for the operation of the transmitter module.
  • Rechargeable batteries of the transmitter module can be charged while the transmitter module is docked in the holder.
  • the data exchange between the transmitter module and the receiver unit can also take place wirelessly in this state. However, it is preferred that the data transfer is wired in the docked state.
  • the transmitter module can have a control means for displaying entered commands and / or for displaying an identifier of a selected road construction machine.
  • This control means can be a display or a means for generating an acoustic, visual or vibratory or haptic signal.
  • Such a display can also be used to show the addressed feedback signals of the receiving module. If a command transmitted by the transmitting module to the receiving module has not been agreed, with a previous command or the state of the road construction machine does not permit the execution of the command, this can also be shown on the display. In addition, it can be provided that states or operating parameters or manufacturing parameters can be shown on the display at any time. Thus, regardless of the location relative to the road construction machine, the operator has access to all information that is necessary for operating the road construction machine.
  • a road paver 10 is shown by way of example with the figure. At this point, however, it should be expressly pointed out that the present invention is not restricted to use for a road paver, but rather can also be seen in connection with other road construction machines, such as a feeder, a road milling machine or the like.
  • the road paver 10 shown as an example in the figure has a chassis 11, which in the exemplary embodiment shown is designed as a crawler chassis.
  • the undercarriage 11 of the road finisher 10 can also be designed as a wheel undercarriage.
  • the paver 10 is self-propelled.

  • the road paver 10 can also be driven in a self-energizing manner in such a way that a movement takes place counter to the production direction 13.
  • a trough-like or trough-like storage container 14 is arranged in front of the drive unit 12.
  • the storage container 14 serves to hold a supply of the material used to produce the road surface, in particular an asphalt mixture.
  • a conveyor not shown in the figure
  • the distributor screw 15 is arranged behind the drive unit 12.
  • the distributor screw 15 extends transversely to the direction of production 13 and serves to evenly distribute the material over the entire working width of the paver 10.

  • the screed 16 is attached to support arms 17 so that it can move up and down.
  • the support arms 17 are pivotally mounted on the chassis 11.
  • the screed 16 can be a one-piece screed 16, the width of which cannot be changed, or a multi-part screed made up of a main screed and lateral shifting screeds, as a result of which the width of the screed and thus the pave width can be changed.
  • the screed 16 has a screed base body 18 with a slide plate 19 arranged underneath.
  • the screed 16 lies with the underside of its sliding plate 19 on the material to be installed.
  • the drive unit 12 of the paver 10 has an internal combustion engine. It is preferably a diesel engine. However, the drive unit 12 can also have other motors, possibly also several motors.
  • the drive unit 12 also has at least one hydraulic pump driven by the internal combustion engine. Hydraulic drives, in particular hydraulic motors, are thus supplied with the required energy. It is also conceivable that the internal combustion engine additionally or alternatively drives at least one generator that generates electricity for electric drives, in particular electric motors.
  • the operation of the paver 10 and the control and monitoring of the listed components, such as the chassis 11, the drive unit 12, the reservoir 14, the auger 15, the screed 16, the support arms 17, and the like can be done by an operator 20 from one Control station 21 can be controlled or checked.

It can be provided that this receiving module 24 is connected directly to the control unit 22 and communicates via this control unit 22 with the individual components via the CAN bus system. Equally, however, it can also be provided that each of the components of the paver 10 mentioned has a corresponding own reception module 24 for communication with the transmission module 23. The communication between the reception module 24 and the transmission module 23 can take place wirelessly. This creates the advantage that the operator 20 is not bound to the control station 21, but rather rather can control the operation of the road paver 10 almost anywhere. Via the transmitter module 23, the operator 20 can either control the individual components via the control unit 22 or access the individual components directly.

  • the range for wireless communication between the transmitter module 23 and the receiver module 24 can be set.
  • An encrypted transmission of the data between the transmitter module 23 and the receiver module 24 can rule out that the data transfer is disrupted or confused with other construction machines.
  • control unit 22 Before starting up the paver 10, the control unit 22 must verify that the transmitter module 23 used is authorized to communicate with the receiver module 24. This can be done, for example, by exchanging an identifier.
  • various command routines or command sequences or groups of commands can be stored on the transmitter module 23 and on the receiver module 24.
  • protocols or operating sequences can be prepared for the work to be carried out, which can be initiated by a simple key combination and was preferably remote-controlled.
  • the operating process is simplified and, on the other hand, the ease of use for the operator 20 can be improved since the person 20 does not have to be constantly on the paver 10 or in the control station 21. As a result, the time that the operator 20 must be directly on the paver 10 can also be reduced.
