System used for improving automatic control of machine operations of construction site machinery

A system configured for confirming a cooperative target being automatically tracked and measured in order to automatically control a machine operation of a construction site machine, comprising:

• at least one total station or theodolite having:
• a tracking unit configured for tracking and continuously measuring the cooperative target within a tracking field of view, wherein measuring relates to the determination of a distance to the cooperative target and of a horizontal and vertical angles to the cooperative target within a coordinate system, an optical distance meter for measuring an optical distance to the cooperative target, wherein the cooperative target is mobile, and
• an ultra-wide band signal transceiver (UWBST) anchor-module, being referenced to the coordinate system, and having an anchor-identifier (anchor-ID),
• the cooperative target being associated with a UWBST tag-module having a tag-identifier (tag-ID) and being used for automatically controlling the machine operation of the construction site machine,
• a machine control unit associated with the construction site machine configured for controlling a plurality of machine operations based on tracking and continuously measuring a plurality of cooperative targets wherein tracking and continuously measuring is carried out by the total station or theodolite, and
• an ultra-wide band (UWB) distance meter associated with the UWBST anchor-module configured for measuring a distance (UWB-distance) between the UWBST anchor-module and the UWBST tag-module and providing the measured UWB-distance with the assigned tag- and anchor-IDs to the machine control unit,
• wherein the machine control unit is configured for matching measured optical distances to measured UWB-distances and using the matching as confirmation that the cooperative target being tracked and continuously measured by the total station or theodolite is the cooperative target being used for automatically controlling the machine operation,
• the system further comprising:
• a further UWBST anchor-module being referenced to the coordinate system and having a further anchor-identifier (anchor-ID), and
• a further UWB-distance meter associated with the further UWBST anchor-module configured for measuring a further UWB-distance between the further UWBST anchor-module and the UWBST tag-module and providing the measured further UWB-distance with the assigned tag- and anchor-IDs to the machine control unit,
• wherein the machine control unit is further configured for:
• determining and assigning a horizontal angle (UWB-angle) to the measured further UWB-distance, under which UWB-angle the UWBST tag-module is located in view of the total station or theodolite and in relation to the further UWBST anchor-module, and
• matching the horizontal angle under which the optical distance is measured and which is determined by the tracking unit to the UWB-angle.
