Unmanned control system for stacker reclaimers in stockyard

Abstract

The invention provides an unmanned control system for stacker reclaimers in a stockyard. The unmanned control system comprises a three-dimensional laser scanner unit, a central control machine, a stacker reclaimer automatic control system, a safety protection system and a video monitoring system, wherein the three-dimensional laser scanner unit is used for acquiring stockyard stockpile three-dimensional models; the central control machine is used for obtaining stacking and reclaiming positioning data of the stacker reclaimers according to the stockyard stockpile three-dimensional models and stacking and reclaiming strategies; the stacker reclaimer automatic control system is used for controlling the stacker reclaimers to perform automatic positioning and automatic stacking and reclaiming operation according to the stacking and reclaiming positioning data of the stacker reclaimers, operation parameters of the stacker reclaimers and the stacking and reclaiming strategies; the safety protection system is used for performing active anti-collision calculation according to data of the stockpile three-dimensional models, equipment positioning detection signals and equipment action state information so as to ensure safe operation of equipment; the video monitoring system comprises a plurality of high-definition cameras mounted on each of the stacker reclaimers; and the video monitoring system is used for observing the action of key equipment of the stacker reclaimers and collecting stockyard video information to the central control machine for centralized monitoring. The unmanned control system for the stacker reclaimers in the stockyard achieves the automatic stacking and reclaiming operation of the stacker reclaimers, and is safe, efficient and unmanned.

Description

technical field [0001] The invention belongs to the field of control engineering, and in particular relates to an unmanned control system for a stacker and reclaimer in a raw material yard. Background technique [0002] At present, the level of automation and intelligence in my country's iron and steel enterprises is not enough, and there is a large number of manual interventions in production, resulting in unstable product quality and low production efficiency. As the first process before iron and steel production, the raw material yard plays an important role and is the reprint interface for the connection between iron and steel enterprises and social logistics. The main task of the raw material plant is to be responsible for the unloading, storage, granulation, mixing, etc. of bulk bulk raw materials and fuels in the whole plant, and to deliver the processed materials to users such as ironmaking, sintering, pelletizing, coking, etc. , to ensure normal and continuous prod...

AI Technical Summary

Problems solved by technology

Compared with the three-dimensional stockyard map, the three-dimensional effect of the two-dimensional stockyard map is worse, and the display accuracy is lowered, which is not conducive to the automatic operation of the stacker and reclaimer

At the same time, many domestic iron and steel enterprises have also proposed the construction goal of unmanned stockyards in response to this problem, but the efficiency of the stacker-reclaimer operation is low, which will affect the subsequent operations of iron and steel production.
