Abstract
The invention relates to a method for operating a plurality of construction machines, in particular in the form of cranes, the movements of which are monitored for imminent collisions by an anti-collision device, wherein ultra-wideband transmitting/receiving devices mounted on the plurality of construction machines exchange ultra-wideband signals, wherein the propagation times of the ultra-wideband signals between the construction machines are determined and imminent collisions are determined from the propagation times of the ultra-wideband signals.
Claims20
A method for operating a plurality of construction machines, the method comprising:
- monitoring the movements of cranes for an imminent collision by an anti-collision device wherein ultra-wideband transmitting/receiving devices mounted on the plurality of construction machines exchange ultra-wideband signals, wherein the propagation times of the ultra-wideband signals between the construction machines are determined and imminent collisions are determined from the propagation times of the ultra-wideband signals.
An anti-collision device for monitoring and avoiding imminent collisions between two construction machines comprising cranes, the device comprising:
- a plurality of ultra-wideband transmitting/receiving devices on each of the construction machines for exchanging ultra-wideband signals,
- a propagation time determination device for determining the propagation times of the ultra-wideband signals exchanged between the construction machines, and
- a position and/or proximity determination device for determining the position of the construction machines relative to each other and/or the proximity of the construction machines to each other by the determined propagation times of the ultra-wideband signals.
A construction machine comprising a crane, comprising:
- an anti-collision device for monitoring and avoiding imminent collisions with another construction machine, wherein the anti-collision device has a plurality of ultra-wideband transmitting/receiving devices spaced apart from one another, and wherein the a plurality of ultra-wideband transmitting/receiving devices are configured to exchange ultra-wideband signals with ultra-wideband transmitting/receiving devices on another construction machine.
