Method for accurate positioning and control of coal stacking and reclaiming

Abstract

The invention relates to a method for precise positioning and control of stacking and taking coal. The coal stacking operation is based on incoming coal information and the cargo location of the raw material yard, and a stacking operation plan is compiled. When the plan is executed, the planned cargo location is compared with the actual operation cargo location. When the two do not match, an alarm will be given to the stacking operation to avoid the mixed quality of coal washing caused by misoperation. Coal fetching operation is based on the material information of the bucket chute and the location of the raw material yard, and the material picking operation plan is compiled. When the plan is executed, the actual operation location is compared with the planned location and the location of the hopper for the coal in the bucket chute. The three do not match. When the reclaiming operation is carried out, the alarm will be given, and the reclaiming operation will be stopped to avoid the mixed quality of coal washing caused by misoperation.

Description

technical field [0001] The invention relates to a method for accurately positioning and controlling coal stacking in a raw material yard. Background technique [0002] The raw material yard has multiple storage positions. Different coal types are stored in different cargo positions, and the stacker puts the washed coal transported by train or sea into corresponding cargo positions according to the coal type and origin. The reclaimer takes the washed coal and sends it to the coal preparation hopper according to the coal use plan of the hopper every day according to different coal types and demand. [0003] The incoming coal and stockpiling information of the original stacker operation, and the operation information of the reclaimer are all transmitted by manual intercom, and manually recorded after operation, which is prone to accidents of coal washing and mixed quality stored in raw material places caused by information transmission or misoperation. Mixed quality accident ...

Problems solved by technology

[0003] The incoming coal and stockpiling information of the original stacker operation, and the operation information of the reclaimer are all transmitted by manual intercom, and manually recorded after operation, which is prone to accidents of coal washing and mixed quality stored in raw material places caused by information transmission or misoperation. Mixed quality accident of coal washing in tank storage

When the quality of coal washing fluctuates, the stacking process cannot be traced, resulting in unclear analysis of the cause of the accident
