Embodiment Construction

[0056]The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0057] Such as figure 1 As shown, two or more stackers and reclaimers will be set in the large-scale stockyard, the first stacker and reclaimer 1 and the second stacker and reclaimer 2 on the adjacent two tracks 3 and 4, their booms The sum of the distances from the front end point to the center of rotation is greater than the distance between the two tracks 3 and 4 where the two stackers and reclaimers are located, so there is a risk of collision between two adjacent stackers and reclaimers during the working process.

[0058] In the technical solution provided by this embodiment, the anti-collision control process of the stockyard stacker-reclaimer obtains the position information of the first stacker-reclaimer 1 and the second stacker-reclaimer 2 through the GPS positioning device, and obtains the first position information through the rotary angle encoder....

Abstract

The invention provides an anti-collision control method for stock yard stacker-reclaimers. Position information, rotary angle information and pitching angle information of the stacker-reclaimers are transmitted to an industrial personal computer through a network, anti-collision control calculation is conducted in the industrial personal computer, the shortest distance between the stacker-reclaimers is compared with a set range value, and corresponding control information is sent to PLCs of the two stacker-reclaimers of adjacent rails according to a comparison result. The PLCs of the two stacker-reclaimers conduct corresponding control and alarm reminding according to the received control information, so that the two stacker-reclaimers are prevented from colliding with each other. Spheres can be virtualized to surround objects or part of the objects so as to judge whether the object collides with another object or not, if the distance between the sphere centers of the surrounding spheres of the two objects is larger than the sum of the radiuses of the two spheres, the two objects do not collide with each other, or else the two objects probably collide with each other. The industrial personal computer calculates the shortest distance between the two stacker-reclaimers by arranging the two-level surrounding spheres of the stacker-reclaimers.

Description

technical field [0001] The invention relates to the technical field of operation control of bulk material stacking and reclaiming operation equipment, in particular to an anti-collision control method for a stockyard stacking and reclaiming machine. Background technique [0002] With the development of technology, bulk material (coal, ore, etc.) stockyards are becoming larger and larger, and there are multiple stacker-reclaimers operating in large-scale bulk material stockyards, and the stacker-reclaimer With long booms, there is a high potential for collisions between stackers and reclaimers. Once a collision occurs, it will cause damage to the stacker-reclaimer, seriously causing casualties and economic losses. The reasons for the collision of the stacker-reclaimer include personnel operation factors, weather factors, and surrounding environmental factors. Therefore, to overcome the influence of these external factors, it is of great significance to invent an automatic a...
