Problems solved by technology

[0002] In particular, there will always be collisions in environments with containers in the stack area, which can lead to death in some cases
Previous collision avoidance solutions are only suitable to a limited extent, since they can only play an auxiliary role (the crane operator and correspondingly trained operators are responsible) and, on the other hand, have a relatively high error rate

Embodiment Construction

[0034] figure 1 A schematic view of a crane 2 is shown, which is implemented in the figure as a gantry crane (for example as an RTG, "Rubber Tyred Gantry"). A load 1 , in the figure a container, is secured to a container spreader 15 ("Spreader") which can be moved from left to right by means of a trolley 14 ("Trolley") in the figure. The load 1 will move along a trajectory 4 , wherein a height profile 6 (“container hill”) is determined at least along the trajectory 4 by at least two sensors 5 for distance measurement. Along the trajectory 4 there are obstacles 3 such that the loads cannot be transported to their destination in a direct path (shown in dashed lines). By means of the method according to the invention, the trajectory 4 is adapted to a parabolic movement, which passes the obstacle 3 safely.

[0035] figure 2 A diagram of at least two sensors 5 for distance measurement is shown, each connected to a controller 8 via a channel 7 . The controller 8 has at least tw...

Abstract

The invention relates to a method and to a system for preventing a collision of a load of a crane (2) with an obstacle (2) and to a crane (2) having such a system, to a program for carrying out such amethod, and to a computer-readable medium having such a program. The aim of the invention is to provide a solution for collision avoidance which meets a safety level. This aim is achieved by a solution, in which the load is moved along a trajectory (4), wherein a height profile is captured at least along the trajectory (4) by means of at least two sensors (5) for distance measurement, wherein signals of the sensors (5) are transmitted via at least two communication channels (7) to a controller (8) having at least two operating systems (9, 10), of which at least one has a safety program in a secure area, wherein an obstacle (2) is identified along the trajectory (4) by means of the height profile. The controller (8) also has a secure communications interface (13) for transmitting signals from the controller (8) to a crane control.

Description

technical field [0001] The present invention relates to a method and a system for avoiding collisions of a load of a crane with obstacles as well as a crane having such a system, a program for performing such a method and a computer readable medium having such a program. Background technique [0002] In particular, in environments with containers in the stack area there will always be collisions, which can lead to death in some cases. Previous collision avoidance solutions are only suitable to a limited extent, since they can only play an auxiliary role (the crane operator and correspondingly trained operators are responsible) and, on the other hand, have a relatively high error rate. In crane types in which the crane driver travels together with the trolley, obstacles cannot be directly observed when reversing. Contents of the invention [0003] The object of the present invention is to provide a solution for collision avoidance that meets a certain level of safety. [...
