Anti-collision method, device and computer-readable storage medium

Abstract

The invention discloses a collision prevention method and device and a computer-readable storage medium. The distance between two mechanical shafts and the actual motion status of the two mechanical shafts can be determined by monitoring the position and motion parameters of the first and second mechanical shafts sharing the same rail, according to the corresponding relationship between the presetminimum safety distance and the state of the motion, the minimum safety distance corresponding to the actual motion status of the two mechanical shafts is determined and used as the target safety distance, and the fact that when one mechanical shaft suddenly stops, the other mechanical shaft cannot collide with the stopped mechanical shaft can be ensured by the minimum safety distance. Accordingto the collision prevention method, when the difference between the distance between the two mechanical shafts and the target safety distance is not in the preset range, the motion parameters of at least one shaft of the two mechanical shafts can be adjusted so as to avoid the fact that the distance between the two mechanical shafts is lower than the target safety distance, therefore, even if themechanical shaft is stopped in the moving process due to the fault and power loss, the shaft collision cannot happen, and the loss of the property due to the collision and the adverse influence on theproduction progress are avoided accordingly.

Description

technical field [0001] The present application relates to the field of industrial automation production, in particular to an anti-collision method, device and computer-readable storage medium. Background technique [0002] At present, during the processing of the two-axis machine tool with common guide rails, one or two mechanical axes may stop due to factors such as self-fault, peripheral alarms, or sudden power failure of the external power grid. When this situation occurs , Interference events such as collisions between mechanical axes are likely to occur, resulting in damage to the mechanical axes and even the machine tool, not only causing property losses, but also delaying the processing process and affecting production. Contents of the invention [0003] Embodiments of the present application provide an anti-collision method, device, and computer-readable storage medium, which can reduce the probability of an interference event occurring on a mechanical axis of a co...
