Method and system for predicating collision possibility as well as anti-collision control method and system

Abstract

The invention discloses a method and a system for predicating the collision possibility of a plurality of stackers-reclaimers in a stack yard as well as anti-collision control method and system. The method for predicating the collision possibility of the plurality of stackers-reclaimers in the stack yard comprises the following steps of: detecting the position information of a mobile station arranged in the large-machine rotary centre of each stacker-reclaimer and the large-arm head centre of the stacker-reclaimer based on a reference station; determining the minimum distance between the large arms of any two stackers-reclaimers in the plurality of stackers-reclaimers according to the detected position information of each stacker-reclaimer; and judging the collision possibility of the large arms of two stackers-reclaimers according to the minimum distance. Therefore, the invention can judge the collision possibility between the stackers-reclaimers so that operators can further process according to the possibility.

Description

technical field [0001] The present invention relates to the field of control engineering, in particular to a method and system for predicting the collision possibility of multiple stackers and reclaimers in a stockyard, and an anti-collision control method and system. Background technique [0002] During stacking and reclaiming operations, it is often necessary to use multiple reclaimers for operations in a storage yard, for example, figure 1 It is a schematic diagram of the operation of the stacker-reclaimer in the stockyard, wherein there may be more than one reclaimer 20 walking along a walking track 30 in a stockyard 10, and in the process of walking, the size of a plurality of reclaimers 20 There is a possibility of a collision between the arms. [0003] At present, there is no effective way to make the staff know in advance that a collision may occur between the stackers and reclaimers 20 before the collision will occur, but only through manual observation, which wast...
