Abstract

The self-propelled construction machine I according to the present invention has a DGNSS rover unit 14 for receiving satellite signals of the global navigation satellite system and correction signals of a reference station 15 arranged in the vicinity of the self-propelled construction machine. The DGNSS rover unit 14 includes a calculation and evaluation unit 18 configured to determine construction machine position data describing the position of a construction machine reference point R on the construction machine based on the satellite signals and the correction signals of the reference station. The calculation and evaluation unit 18 is further configured to generate at least one machine readable dataset, in particular a QR code, for the reference station position dataset stored in the reference station position data memory device 23, which dataset is displayed on the display 8A. The QR code may be scanned by the smart phone 26 installed with the map service having the navigation function so that the set point for setting the reference station may be easily found at the construction site. In alternative embodiments, the data may also be scanned using an NFC receiving unit (NFC reader) based on RFID technology.

Description

Self-propelled construction machine, and apparatus comprising a self-propelled construction machine and a mobile terminal, and method for locating a reference station setpoint of a reference station arranged in the vicinity of a self-propelled construction machine Technical Field The invention relates to a self-propelled construction machine having a frame supported by a travelling mechanism and a working device for working or building a structure on a work site, wherein the self-propelled construction machine comprises a DGNSS rover unit for receiving satellite signals from a global navigation satellite system and correction signals from a reference station arranged in the vicinity of the self-propelled construction machine, and the DGNSS rover unit has a calculation and evaluation unit configured to determine construction machine position data describing the position of a construction machine reference point on the construction machine in a coordinate system independent of the construction machine based on the satellite signals and the correction signals from the reference station. The invention also relates to a device comprising a self-propelled construction machine having a frame supported by a travelling mechanism, and a working device for working or building a structure on a site, and a mobile terminal. Furthermore, the invention relates to a method for locating a reference station setpoint of a reference station arranged in the vicinity of a self-propelled construction machine. Background A self-propelled construction machine is understood to mean all construction machines on which a working device is arranged on a frame for building a structure at a worksite or for retrofitting a worksite. Well known self-propelled construction machines include, for example, road milling machines, stabilizers, recyclers, slipform pavers and road pavers. In road milling machines or recyclers, the working device comprises a milling/cutting drum equipped with a milling or cutting tool, by means of which material can be removed from the work site within a specified working width. The working device of a slipform paver is a device for shaping flowable materials, in particular concrete, by means of which structures of different designs, such as guide walls or traffic islands, can be produced. Known road pavers comprise a paving screed for paving the road material. Soil compactors, such as road rollers, have at least one compacting device for compacting the subsoil. During construction of structures on the ground or during reconstruction of a worksite, high demands are placed on the accuracy of the construction work. Accordingly, in the control of self-propelled construction machines, the goal has increasingly been to relieve the burden on the machine operator, who is burdened with a number of tasks during the construction work. Thus, known self-propelled construction machines use a position determination system that determines the position of a reference point on the self-propelled construction machine in a coordinate system independent of the construction machine. The term GPS (global positioning system) is used to describe a position determination system based on the evaluation of signal propagation times of signals from a plurality of satellites. The abbreviation GPS is nowadays used in spoken language and even sometimes in technical language as a generic term or in partial substitution as a whole for all satellite navigation systems which are correctly categorized under the abbreviation GNSS (global navigation satellite system) (wikipedia: GPS). The terms DGPS (differential global positioning system) or DGNSS are used to describe a method for improving the accuracy of GNSS position determination by transmitting correction signals (orbit and time system). DGNSS may also use a fixed reference station, called a base station, which can very accurately determine the actual propagation time of each satellite signal from the deviation between the actual position and the received position. The difference between the theoretical signal propagation time and the actual signal propagation time is transmitted to a DGNSS receiver, which uses these correction signals to correct their position (wikipedia: DGPS). Hereinafter, a GPS rover unit or a GNSS rover unit is also understood to refer to a DGPS or DGNSS rover unit or vice versa, wherein the terms (D) GPS and (D) GNSS are used as synonyms in this context. DE 197 56 676 C1 describes a road milling machine with DGNSS for position determination. The construction machine has a DGNSS rover unit for receiving satellite signals of a global navigation satellite system and correction signals of a reference station, wherein the DGNSS rover unit is configured to determine position data describing a reference point on the construction machine in a coordinate system independent of the construction machine based on the satellite signals and the correction signals.
