Definitions

  • the invention relates to a construction machine, in particular a civil engineering device, with at least one actuator and a sensor for determining a geographic position. Furthermore, the invention relates to a system in which a construction machine is used and a method for determining operating parameters for operating at least one actuator of the construction machine.
  • a construction machine has a control and evaluation device for determining operating parameters for the at least one actuator, depending on the geographic position.
  • the control and evaluation device is set up to query a database to determine the operating parameters depending on the geographic position and to limit the operation of the at least one actuator to the determined operating parameters depending on the geographic position.
  • the permissible operating parameters can also have a larger range than in standard operation. Accordingly, one can also speak of unlocking additional functions.
  • the construction machine can also be a stationary construction machine that can be transported to other geographical areas using appropriate external means of transport.
  • the construction machine is designed as a mobile civil engineering device with a chassis. It is precisely in such a case that the advantages of the invention come into play, since the manufacturer himself can hardly influence where the construction machine is used or which methods are carried out where with the construction machine.
  • the sensor for determining a geographic position can be designed for satellite-based position determination.
  • the position can be determined according to the GPS, Galileo, Glonass and/or Beidou standard, for example. To increase the accuracy, it can be provided that several of these standards are used at the same time. In principle, however, other options for determining the geographic position are also conceivable. For example, when starting the machine it may be necessary to enter the relevant country or region, or determining the country or the position of the machine is achieved by recognizing the existing country-specific mobile phone networks or the exact location area by determining surrounding radio masts.
  • the satellite-supported position determination which is ideally carried out independently by the construction machine or by means of the control and evaluation device, makes it possible to ensure in a particularly simple manner that no misuse takes place.
  • the senor for determining a geographic position can be designed to determine the position by determining surrounding transmitter stations of a mobile radio network.
  • the sensor recognizes, for example, in which country the construction machine is based on the existing radio networks. It is also possible that, based on specific transmission stations, it can be determined in which area the construction machine is located.
  • the operating parameters for the at least one actuator can be, for example, the driving speed, the traction, the speed, the torque, a Act pressure, a volume flow, a motor speed, a temperature, a voltage or a current. It can also z. B. noise emissions from a drive motor or noise emissions to be expected when operating an attachment such as a vibrator can be controlled accordingly. It is thus possible to carry out certain construction processes in inhabited areas in a noise-reduced mode, while outside of town it is possible to switch to a more noisy but faster mode. Another example is the use of devices or controls to assist equipment drivers, to automate processes or to comply with country-specific regulations and laws. Of course, other operating parameters are also possible, such as limiting the radius of action of the construction machine on the construction site or on the construction site itself depending on the existing construction site facilities.
  • the construction machine according to the invention is preferably used in a system for determining operating parameters for at least one actuator of the construction machine.
  • the system has a database that contains different operating parameters for different actuators depending on different geographical positions. With such a system, it is possible for the construction machine to independently search the database for permissible operating parameters, depending on the geographic position determined, and to take these operating parameters into account during operation.
  • operating parameters can represent a range of permissible parameters and define a minimum or maximum parameter. This can also be understood to mean the combination of different operating parameters with one another, for example to prevent the execution of certain patent-protected methods.
  • the database can be provided locally in, on or in the vicinity of the construction machine or it can also be arranged remotely from the construction machine. In the second case, it can be queried via a data connection that can be set up directly or indirectly by the construction machine.
  • the database can be updated regularly during maintenance work by the manufacturer. For example, it is possible to react to the expiry of a patent or to adapt operating parameters to new legal requirements.
  • This version offers the advantage that it is not absolutely necessary to wait for a local database to be updated in order to take current patent specifications into account.
  • the database can also be stored on a cloud service and thus be available on several servers. This ensures higher availability.
  • the database has different operating parameters for different actuators depending on a national territory, a region, a local area and/or a freely definable area.
  • the database can also have different operating parameters for different actuators depending on patent law, legal, safety-related, company-specific and/or manufacturer-specific specifications.
  • An application example is the operation of a civil engineering machine in a nature reserve or water protection area. In this case, it must be ensured that the internal pressure of a machine operated underground is lower than the external pressure, so that gear oil, for example, cannot enter the groundwater if the housing leaks.
  • time limit Another possibility is a time limit. This means that certain operating modes are not permitted by law during a certain time, for example at night, but are possible during the day. As with the temporal limitation, this can also be a seasonal or date-based limitation.
  • the construction machine can determine the exact geographic coordinates, ie its position, by means of the control and evaluation device.
  • a query of the database reveals that although the location is in Germany, the local area, in this case the water protection area, has even stricter regulations.
  • the control and evaluation device uses the narrowest or strictest operating parameter when querying the permissible operating parameters if there are several operating parameters for the same actuator.
  • the invention relates to a method for determining operating parameters for operating at least one actuator of a construction machine, a geographical position of the construction machine being determined by means of a sensor. At least one additional operating parameter for the at least one actuator of the construction machine is determined by means of a control and evaluation device, depending on the geographic position. The operation of the at least one actuator is then limited by means of the at least one permissible operating parameter determined as a function of the geographic position.
  • the at least one permissible operating parameter for the at least one actuator of the construction machine is preferably determined in a database as a function of the geographic position. This can either be available locally on the construction machine or can be queried via a data connection.
  • the database can be located, for example, on a construction site or can also be queried via a data network on the Internet.
  • the database includes allowable operating parameters for the at least one actuator at a state, regional, territory, or designated area level, where the respective lowest common allowable operating parameter is retrieved and used to limit the operation of the at least one actuator.
  • allowable operating parameters for the at least one actuator at a state, regional, territory, or designated area level, where the respective lowest common allowable operating parameter is retrieved and used to limit the operation of the at least one actuator.
  • the exhaust emission can also be regulated in a similar way.
  • different permissible exhaust emissions may be specified.
  • the use of AdBlue may be necessary to reduce exhaust emissions, but this is not necessary in all areas of application.
  • the construction machine 10 is located in an area 52 in a country 51.
  • a country 53 is shown adjoining the country 51.
  • the control and evaluation device 16 causes the sensor 14 to determine the geographic position to determine the latter. This can be a GPS sensor, for example. Based on the geographic position and with the knowledge of which actuators 12 are present in the construction machine 10 , the control and evaluation device 16 now queries a database 20 for corresponding operating parameters for the actuators 12 . In the embodiment shown here, two databases 20 are provided. One is inside the construction machine 10. The other is provided remote from the construction machine on the Internet 21.
  • Corresponding operating parameters for example for the country 51 and for the country 53, are stored in the database.
  • control and evaluation device 16 can, under certain circumstances, query different operating parameters for the same actuator 12 . However, the smallest or narrowest operating parameter is used to limit the operation of the actuator 12 . In a similar way, it is also possible for the database 20, based on a query by the control and evaluation device 16, to supply only one operating parameter that already meets this specification.
  • operating parameters can also be understood to mean a range of permitted operation and a maximum or minimum value.
